Clinicopathologic Features of Therapy-Related Myeloid Neoplasms in Patients with Myeloma in the Era of Novel Therapies.
    Modern pathology : an official journal of the United States and Canadian Academy of Pathology, Inc, 2023, Volume: 36, Issue:6

    The development of therapy-related myeloid neoplasms (t-MN) is a rare complication that can occur in myeloma patients treated primarily with novel therapies. To better understand t-MNs in this context, we reviewed 66 such patients and compared them with a control group of patients who developed t-MN after cytotoxic therapies for other malignancies. The study group included 50 men and 16 women, with a median age of 68 years (range, 48-86 years). Therapies included proteasome inhibitors, immunomodulatory agents, and high-dose melphalan-based autologous stem cell transplantation (HDM-ASCT) in 64 (97%), 65 (98.5%), and 64 (97%) patients, respectively; 29 (43.9%) patients were exposed to other cytotoxic drugs besides HDM. The latency interval from therapy to t-MN was 4.9 years (range, 0.6-21.9 years). Patients who received HDM-ASCT in addition to other cytotoxic therapies had a longer latency period to t-MN compared with patients who only received HDM-ASCT (6.1 vs 4.7 years, P = .009). Notably, 11 patients developed t-MN within 2 years. Therapy-related myelodysplastic syndrome was the most common type of neoplasm (n = 60), followed by therapy-related acute myeloid leukemia (n = 4) and myelodysplastic syndrome/myeloproliferative neoplasm (n = 2). The most common cytogenetic aberrations included complex karyotypes (48.5%), del7q/-7 (43.9%), and/or del5q/-5 (40.9%). The most frequent molecular alteration was TP53 mutation, in 43 (67.2%) patients and the sole mutation in 20 patients. Other mutations included DNMT3A, 26.6%; TET2, 14.1%; RUNX1, 10.9%; ASXL1, 7.8%; and U2AF1, 7.8%. Other mutations in less than 5% of cases included SRSF2, EZH2, STAG2, NRAS, SETBP, SF3B1, SF3A1, and ASXL2. After a median follow-up of 15.3 months, 18 patients were alive and 48 died. The median overall survival after the diagnosis of t-MN in the study group was 18.4 months. Although the overall features are comparable to the control group, the short interval to t-MN (<2 years) underscores the unique vulnerable status of myeloma patients.

[Updated treatment strategy for transplant-eligible multiple myeloma: current status and future perspectives].
    [Rinsho ketsueki] The Japanese journal of clinical hematology, 2023, Volume: 64, Issue:9

    Treatment outcomes of multiple myeloma (MM) have dramatically improved in the past 20 years. The IFM/DFCI group reported that triplet induction (bortezomib, lenalidomide, and dexamethasone), followed by up-front high-dose melphalan and autologous stem cell transplantation (HDM/ASCT) and maintenance therapy, demonstrated a median progression-free survival (PFS) of 50 months. Therefore, up-front HDM/ASCT is considered standard care even in the era of novel agents. Daratumumab, lenalidomide, and dexamethasone have also been reported to prolong PFS for newly diagnosed transplant-ineligible MM. Quadruplet induction, including anti-CD38 antibody, will be approved even for transplant-eligible MM soon. Conversely, the success of chimeric antigen receptor T-cell therapy revealed that cellular immunotherapy may play an important role in treating MM. This review discussed the current standard of care and future perspectives for transplant-eligible MM.

Melphalan: Recent insights on synthetic, analytical and medicinal aspects.
    European journal of medicinal chemistry, 2022, Aug-05, Volume: 238

    Cancer is an uncontrolled expansion of atypical cells in the body. These unusual cells are labelled as cancerous or malignant cells. Melphalan, an anticancer drug which is imperatively recognized under the class of alkylating agents. It exhibits broad spectrum antitumor activity, as observed in ovarian cancer, breast cancer, etc. However, it is mainly utilized in the management of multiple myeloma. Several studies across the globe suggest that resistance to melphalan is the major concern that leads to relapsed myeloma. In the present paper, several pivotal approaches to compensate resistance associated with melphalan have been discussed. Numerous chemical and formulation developments concerning melphalan to enhance its salient characteristics and targeted profile have also been portrayed. The rationale of the current article also summarizes the recent analytical methods, structure-activity relationship, pharmacokinetics, interactions, potential adverse effects along with medicinal updates of melphalan. Special attention is also laid on their synthetic developments viz. melphalan derivatives, conjugates and prodrugs along with encouraging insights and research findings.

How I treat frontline transplantation-eligible multiple myeloma.
    Blood, 2022, 05-12, Volume: 139, Issue:19

    High-dose melphalan supported by autologous transplantation has been the standard of care for eligible patients with newly diagnosed multiple myeloma (MM) for >25 years. Several randomized clinical trials have recently reaffirmed the strong position of transplantation in the era of proteasome inhibitors and immunomodulatory drugs combinations, demonstrating a significant reduction of progression or death in comparison with strategies without transplantation. Immunotherapy is currently changing the paradigm of MM management, and daratumumab is the first-in-class human monoclonal antibody targeting CD38 approved in the setting of newly diagnosed MM. Quadruplets have become the new standard in transplantation programs, but outcomes remain heterogeneous, with various response depth and duration. The development of sensitive and specific tools for disease prognostication allows the consideration of strategies adaptive to dynamic risk. This review discusses the different options available for the treatment of transplantation-eligible patients with MM in frontline setting.

Pepaxto: A New Peptide-Drug Conjugate for Heavily Pretreated Relapsed and Refractory Multiple Myeloma.
    The Annals of pharmacotherapy, 2022, Volume: 56, Issue:8

    The objective of this article was to review existing data of melflufen (Pepaxto) as an additional treatment option for heavily pretreated relapsed and refractory multiple myeloma.. A PubMed search was completed using the search terms melphalan flufenamide; melflufen; melflufen AND relapsed refractory multiple myeloma; melphalan flufenamide and relapsed refractory multiple myeloma between January 1, 2013, and October 18, 2021. Additional information was obtained from the National Institutes of Health Clinical Trial Registry, Federal Drug Administration (FDA) web updates, and Pepaxto prescribing information.. Clinical trials including melflufen in relapsed refractory multiple myeloma and trials related to safety and clinical pharmacology were included.. The findings of this review show melflufen in combination with dexamethasone can be used as a treatment option for patients with relapsed and refractory multiple myeloma who have previously received greater than 4 previous lines of therapy, and documented resistance to a proteosome inhibitor, an anti-CD38 monoclonal antibody, and an immunomodulator.. Melflufen in combination with dexamethasone is a reasonable option for patients with relapsed and refractory multiple myeloma who have received at least 4 previous lines of therapy and considered ineligible for autologous stem cell transplant. Further clinical utilization in earlier lines of therapy is under review, pending the in-depth safety analysis by the FDA.. The FDA approval of melflufen in combination with dexamethasone provides an additional therapy option for patients with heavily pretreated relapsed and refractory multiple myeloma.

The era of lenalidomide maintenance therapy in multiple myeloma: settings for achieving best outcomes.
    Expert review of clinical pharmacology, 2022, Volume: 15, Issue:1

    For patients with multiple myeloma who are eligible for high-dose melphalan therapy and autologous stem cell transplant (ASCT), the strategy of maintenance with low-dose lenalidomide therapy has become the current standard of care. However, this strategy is not curative, and many unanswered questions remain regarding the optimization of lenalidomide-based maintenance therapy.. In this review, we evaluate the current data supporting the use of lenalidomide maintenance, either alone or in combination, following ASCT. We provide an overview of the management of lenalidomide-associated toxicities as well as address the unresolved topics of optimal treatment duration and use of minimal residual disease assessment.. While single-agent lenalidomide maintenance is a current standard of care, a one-size-fits-all approach to maintenance therapy is not optimal. The rapidly evolving landscape of multiple myeloma therapy in conjunction with ongoing clinical trials should enable a future where an individualized approach based on disease characteristics, response to induction and ASCT (or even non-ASCT consolidation approaches such as CAR T-cell therapy or bispecific antibodies), as well as patient preferences will influence the use of lenalidomide maintenance.

High dose (conditioning) regimens used prior to autologous stem cell transplantation in multiple myeloma.
    Transplantation and cellular therapy, 2022, Volume: 28, Issue:9

    The use of autologous stem cell transplantation (ASCT) in multiple myeloma (MM) is the standard of care in patients who are deemed transplantation eligible. Novel therapies, namely immunomodulatory drugs, proteasome inhibitors, and monoclonal antibodies, have revolutionized the treatment algorithm for MM but have not yet resulted in a cure. To achieve long-lasting disease control in MM, a high-dose conditioning regimen followed by ASCT continues to be an essential part of the management of transplantation-eligible patients with MM. High-dose (or conditioning) regimens are preparative chemotherapy-based regimens used before ASCT. High-dose melphalan is the most commonly used regimen in MM treatment. This clinical review provides an evidence-based summary to guide practicing hematologists/oncologists in the various high-dose regimens used before ASCT in MM treatment. We highlight the use of single-agent melphalan along with various combination-based high-dose regimens with their clinical efficacy. Various dosing schedules and modifications, timing of administration, and novel drugs-based combination regimens are discussed.

Real World Adherence to and Persistence With Oral Oncolytics in Multiple Myeloma: A Systematic Review and Meta-analysis.
    Clinical lymphoma, myeloma & leukemia, 2022, Volume: 22, Issue:10

    Oral oncolytic treatments (OOTs) have improved the prognosis of patients with multiple myeloma (MM). However, the effectiveness of these therapies is undermined by poor adherence. We aimed to characterize the real-world adherence to, and persistence with, OOTs for MM.. MEDLINE, EMBASE, and the International Pharmaceutical abstracts databases were searched for relevant observational studies published in English up to November 21, 2021. This was supplemented by manual searches of abstracts from the annual meetings of the American Society of Hematology, the American Society for Clinical Oncology, and the European Hematology Association as well as screening the references of included articles. Random-effects meta-analysis was performed.. Following screening of 11,557 articles, 19 studies involving 27,129 patients in 8 countries (France, the US, Germany, Italy, the UK, Brazil, South Korea, and Belgium) prescribed OOTs (lenalidomide, thalidomide, pomalidomide, panobinostat, ixazomib, and melphalan) for MM were included. The overall pooled proportion of adherent patients was 67.9% (95% confidence interval [CI]: 57.1%-77.8%). The pooled proportion of adherent patients was higher in self-reported questionnaire-based studies compared to those using prescription/dispensing data (81.6% vs. 61.0%; P-value for difference = .08). Across 5 studies involving 15,363 patients, a pooled proportion of 35.8% (95% CI: 22.0-50.9) discontinued treatment. Factors reported to be associated with nonadherence included increasing age, higher comorbidity, polypharmacy, and a lack of social support.. In patients with MM, adherence to and persistence with OOTs remains suboptimal. To achieve desired clinical outcomes, interventions to improve adherence and minimize discontinuation may be warranted.

Melphalan flufenamide for relapsed/refractory multiple myeloma.
    Drugs of today (Barcelona, Spain : 1998), 2022, Volume: 58, Issue:8

    Despite therapeutic advances and improved patient outcomes in recent years, multiple myeloma (MM) remains a mostly incurable hematologic malignancy. Patients with relapsed/refractory MM (RRMM), especially those with triple-class-refractory disease or poor-prognostic features, have substantially unmet needs for new therapies with novel mechanisms of action. Melphalan flufenamide (melflufen) is the first alkylating peptide-drug conjugate that targets aminopeptidases to show efficacy and manageable safety, in combination with dexamethasone, in patients with RRMM who had received at least 4 prior lines of therapy, including at least 1 immunomodulatory drug, at least 1 proteasome inhibitor and at least 1 anti-CD38 monoclonal antibody, and received accelerated approval by the U.S. Food and Drug Administration (FDA) in early 2021 for use in this patient population. Initial analyses of the phase III OCEAN study data led to melflufen being voluntarily withdrawn from the U.S. market in late 2021, but subsequent analyses have prompted the manufacturer to rescind its voluntary withdrawal to allow further discussions with the U.S. FDA and the regulatory review with the European Medicines Agency (EMA) is also ongoing. Here, we provide a review of the novel mechanism of action and pharmacokinetics of melflufen, as well as key efficacy and safety from clinical studies that supported its initial approval, and discuss the nuances of the OCEAN study data. Melflufen demonstrates the potential of novel peptide-drug conjugates to positively impact the treatment landscape in RRMM.

The mutagenic impact of melphalan in multiple myeloma.
    Leukemia, 2021, Volume: 35, Issue:8

    The introduction of whole genome and exome sequencing partnered with advanced bioinformatic pipelines has allowed the comprehensive characterization of mutational processes (i.e., mutational signatures) in individual cancer patients. Studies focusing on multiple myeloma have defined several mutational processes, including a recently identified mutational signature (called "SBS-MM1") directly caused by exposure to high-dose melphalan (i.e., autologous stem cell transplant). High-dose melphalan exposure increases both the overall and nonsynonymous mutational burden detected between diagnosis and relapse by ~10-20%. Nevertheless, most of these mutations are acquired within the heterochromatin and late-replicating regions, rarely involving key myeloma driver genes. In this review, we summarize key studies that made this discovery possible, and we discuss potential clinical implications.

Spotlight on Melphalan Flufenamide: An Up-and-Coming Therapy for the Treatment of Myeloma.
    Drug design, development and therapy, 2021, Volume: 15

    Despite recent therapeutic advances, multiple myeloma (MM) patients experience relapses as they become resistant to various classes and combinations of treatment. Melphalan (L-PAM) is an ageless drug. However, its use in the autologous stem cell transplantation (ASCT) setting and the innovative quadruplet regimen as well as daratumumab, bortezomib, and prednisone make this old drug current yet. Melflufen is a peptide-conjugated alkylator belonging to a novel class of compounds, representing an overcoming of L-PAM in terms of mechanism of action and effectiveness. The improved melflufen cytotoxicity is related to aminopeptidase activity, notably present in normal and neoplastic cells and remarkably heavily overexpressed in MM cells. Upon entering a cell, melflufen is cleaved by aminopeptidases, ultimately releasing the L-PAM payload and eliciting further the inflow and cleavage of the conjugated peptide. This virtuous loop persists until all extracellular melflufen has been utilized. The aminopeptidase-driven accumulation results in a 50-fold increase in L-PAM cell enrichment as compared with free alkylator. This condition produces selective cytotoxicity, increased on-target cell potency, and decreased off-target cell toxicity, ultimately overcoming resistance pathways triggered by previous treatments, including alkylators. Due to its distinct mechanism of action, melflufen plus dexamethasone as a doublet, and in combination with other novel drugs, has the potential to be beneficial for a broad range of patients with relapsed/refractory (RR) MM in third- or even in second-line therapy. The safety profile of melflufen has been consistent across studies, and no new safety concerns have been identified when melflufen was administered in doublet and triplet combinations. Based on growing clinical evidence, melflufen could be not only a good addition in the fight against RRMM but also a drug with a very favorable tolerability profile.

The role of autologous stem-cell transplantation in multiple myeloma in 2021.
    Current opinion in oncology, 2021, 11-01, Volume: 33, Issue:6

    In this review, we discuss the most important aspects of the role of high-dose melphalan (HDM) and autologous stem-cell transplantation (ASCT) in the treatment of multiple myeloma (MM).. Almost 40 years after the publication of the first study on safety and efficacy of HDM and ASCT in MM patients, and despite the introduction of several drugs and combinations with various targets on the plasma cell and the surrounding microenvironment, HDM-ASCT still stands as a standard of care for the upfront treatment of newly diagnosed MM patients. Indeed, all attempts to replace HDM-ASCT with novel-agent-based, non-transplant strategies have failed to demonstrate their efficacy, at least in terms of progression-free survival.. Despite such a long history in MM, a number of open issues regarding HDM-ASCT still exist, from the choice between using transplant in first-line therapy or at relapse to the use of tandem HDM-ASCT in high-risk patients. With the introduction of more and more effective multidrug regimens and of novel immunotherapeutic approaches, the challenge between transplant and non-transplant is not over yet.

The effects of different schedules of bortezomib, melphalan, and prednisone for patients with newly diagnosed multiple myeloma who are transplant ineligible: a matching-adjusted indirect comparison.
    Leukemia & lymphoma, 2020, Volume: 61, Issue:3

    For patients with newly diagnosed multiple myeloma (NDMM) who are transplant ineligible, bortezomib-melphalan-prednisone (VMP) demonstrated superior efficacy based on the VISTA trial. In subsequent trials, twice-weekly bortezomib was limited to the first cycle or completely replaced with once-weekly bortezomib to reduce toxicity. Following a systematic literature review, the efficacy and safety of modified VMP schedules (pooled data from the once-weekly bortezomib VMP arm of the GIMEMA trial and the VMP arm of the ALCYONE trial) were compared to the VISTA schedule using naïve and unanchored matching-adjusted indirect comparison (MAIC). Median progression-free survival was similar between VISTA and modified VMP (20.7 months [95% CI, 18.4-24.3] vs 19.6 months [95% CI, 18.8-21.0]). Peripheral neuropathy was significantly reduced with modified VMP versus VISTA VMP (all grades: naïve, 32.1% vs 46.8% and MAIC, 32.1% vs 46.7%; both

Relative efficacy of treatment options in transplant-ineligible newly diagnosed multiple myeloma: results from a systematic literature review and network meta-analysis.
    Leukemia & lymphoma, 2020, Volume: 61, Issue:3

    Established treatments for transplant-ineligible (TNE) patients with newly diagnosed multiple myeloma (NDMM) include melphalan and prednisone (MP) combined with either bortezomib (VMP) or thalidomide (MPT), or lenalidomide plus low-dose dexamethasone (Rd). New treatments for TNE NDMM include Rd plus bortezomib (RVd) and daratumumab plus VMP (VMP + D), daratumumab plus lenalidomide and dexamethasone (D + Rd). Relative efficacy of these treatments was compared using a network meta-analysis. Eight trials identified by a systematic literature review were included in the primary analysis; hazard ratios (HRs) for overall survival (OS) and progression-free survival (PFS) were used. Rd was superior to other MP-based regimens for OS and PFS. There was strong evidence that, compared with Rd, both D + Rd and RVd improved PFS (HR 0.57; 95% credible interval (CrI) 0.43, 0.73 and HR 0.72; 95% CrI 0.56, 0.91, respectively). However, there was strong evidence only for RVd in respect to OS (HR 0.72; 95% CrI 0.52, 0.96).

Second malignancies in multiple myeloma; emerging patterns and future directions.
    Best practice & research. Clinical haematology, 2020, Volume: 33, Issue:1

    The changing landscape of treatment options for multiple myeloma has led to a higher proportion of patients achieving deep, long-lasting responses to therapy. With the associated improvement in overall survival, the development of subsequent second malignancies has become of increased significance. The risk of second malignancy after multiple myeloma is affected by a combination of patient-, disease- and therapy-related risk factors. This review discusses recent data refining our knowledge of these contributing factors, including current treatment modalities which increase risk (i.e. high-dose melphalan with autologous stem cell transplant and lenalidomide maintenance therapy). We highlight emerging data towards individualized risk- and response-adapted treatment strategies and discuss key areas requiring future research.

The changing role of high dose melphalan with stem cell rescue in the treatment of newly diagnosed multiple myeloma in the era of modern therapies-back to the future!
    Best practice & research. Clinical haematology, 2020, Volume: 33, Issue:1

    State of the art treatment for myeloma involves using 3-drug combinations incorporating immunomodulatory drugs (IMiDs) and proteasome inhibitors (PIs). Clinical trials for 4-drug combinations incorporating monoclonal antibodies added to IMiD and PI based backbones are underway. Recent retrospective analyses show that patients who attain MRD negativity have similar long term outcomes regardless of early or delayed high dose melphalan with autologous stem cell support (HDM-ASCT). Given HDM-ASCT toxicity, not "overtreating" would be beneficial. Short of data from future prospective clinical trials addressing the question of the role of HDM-ASCT in MRD negative patients, varying expert opinions inherently arise. In this paper, we present the historical context of HDM-ASCT and data supporting 3-drug combinations. We then propose that a viable option for patients who reach MRD negativity is to transition to maintenance therapy directly without early HDM-ASCT, and reserving stem cell harvest to cases where HDM-ASCT is a possibility at relapse.

Modern treatments and future directions for newly diagnosed multiple myeloma patients.
    Best practice & research. Clinical haematology, 2020, Volume: 33, Issue:1

    Over the course of the past decade-plus, the therapy of newly diagnosed multiple myeloma has seen incredible advances in the domains of diagnostic evaluation, active medical therapy, and response evaluation. This manuscript reviews the evaluation and management of newly diagnosed active multiple myeloma, with a focus on major clinical trials and IMWG recommendations. The paper describes a current approach for the initial evaluation and workup for patients with putative active myeloma, with consideration towards potential MRD-directed therapeutic approaches and future clinical trials, and then discusses management with a focus on induction regimens with attention primarily to modern three and four-drug combinations for transplant-eligible and transplant-ineligible patients, and those with organ dysfunction. Finally, this article briefly reviews minimal residual disease directed therapy approaches, primarily in the context of whether eligible patients should be referred for high dose chemotherapy and autologous stem cell rescue. Maintenance therapy for both transplant eligible and ineligible patients is discussed elsewhere in this issue.

The role of high-dose melphalan with autologous stem-cell transplant in multiple myeloma: is it time for a paradigm shift?
    British journal of haematology, 2020, Volume: 191, Issue:5

    Recent advances in multiple myeloma include numerous approvals of novel therapies with unprecedented efficacy, a rapid and sustained tempo of new drug development, and further refinements to prognostication to include minimal residual disease (MRD) testing and improved risk stratification. The upfront use of immunomodulatory drug and proteasome inhibitor combinations followed by maintenance has resulted in transformative clinical benefit. Four-drug regimens incorporating monoclonal antibodies are reporting unprecedented rates of complete response and MRD negativity in the absence of intensification. In the context of these advances, the added value of high-dose melphalan with autologous stem-cell transplant (HDM-ASCT) is a key question. From a safety standpoint, HDM-ASCT is associated with both acute toxicities that reduce quality of life and long-term toxicities that may limit life expectancy for some patients. The present review discusses the recent advances in induction therapy, the impact of these advances on HDM-ASCT, the evolving role of MRD testing and the short- and long-term risks of HDM-ASCT. Recognising that prospective data remains limited, we suggest that HDM-ASCT not be considered mandatory for eligible newly diagnosed patients who are treated with highly efficacious regimens and achieve deep responses, but rather be held in reserve without early exposure to the clinical and genomic toxicity inherent to this approach.

Management of newly diagnosed transplant ineligible multiple myeloma.
    Leukemia & lymphoma, 2020, Volume: 61, Issue:11

    Multiple myeloma (MM) is a chronically managed blood cancer with a median age of 69 years at the time of diagnosis. Although high dose melphalan and autologous stem cell transplantation (ASCT) remains a standard of care for eligible patients, more than half of the newly diagnosed MM patients are deemed ineligible due to comorbidities or complications of the disease by itself. In this setting, where ASCT is deemed inappropriate, patients could still achieve durable and deep responses if given the appropriate treatment plan. The key concepts of optimizing induction and maintenance strategies while minimizing side-effects are discussed in this review, especially in the context of employing novel agent combinations. It is important to understand the balance between safety and efficacy for each regimen, utilizing maintenance strategy and the best supportive care measures (bone health, infection prevention, and treatment, pain management, etc.). Here, we examine the evidence behind each of those principles and review results from clinical trials for transplant-ineligible (TI) MM.

Melflufen for relapsed and refractory multiple myeloma.
    Expert opinion on investigational drugs, 2020, Volume: 29, Issue:10

    The overall survival of patients with multiple myeloma has improved with the advent of novel agents; however, multiple myeloma remains incurable. Combinations of standard-of-care agents such as immunomodulators, proteasome inhibitors, and anti-CD38 monoclonal antibodies are increasingly used in earlier lines of therapy. Patients with disease that is refractory to multiple novel agents represent a population with high unmet medical need and for whom therapies with new mechanisms of action could be beneficial. Melphalan flufenamide (melflufen) has demonstrated encouraging activity in patients with relapsed and refractory multiple myeloma.. This review provides an overview of the mechanism of action of melflufen, a first-in-class peptide-drug conjugate that targets aminopeptidases and rapidly delivers alkylating agents into tumor cells. It reviews key Phase I and II clinical trial data for melflufen in combination with dexamethasone as well as in triplet combinations with daratumumab or bortezomib. The safety profile of melflufen, which is characterized primarily by clinically manageable hematologic adverse events, is described.. Melflufen has potential to fill a gap in the myeloma treatment landscape by providing a new mechanism of action with clinically meaningful efficacy and a favorable safety profile in patients refractory to multiple novel agents.

    CD38 antibodies were first evaluated in extensively pretreated patients with multiple myeloma (MM). Currently, there are 3 CD38 antibody-based regimens approved for the treatment of both transplant-eligible (daratumumab plus bortezomib-thalidomide-dexamethasone [D-VTd]) and transplant-ineligible (daratumumab plus lenalidomide-dexamethasone [D-Rd] or daratumumab plus bortezomib-melphalan-prednisone [D-VMP]) patients with newly diagnosed MM (NDMM). The phase 3 studies that evaluated these regimens uniformly showed that the addition of daratumumab to backbone regimens improved the depth of response, which translated into improved progression-free survival and also overall survival in 2 of the studies. Importantly, elderly patients age 75 years or older benefit from these regimens, indicating that these regimens have an acceptable safety profile. Although the number of patients with high-risk cytogenetics was relatively small, these patients also experienced benefit from the addition of daratumumab to standard-of-care regimens, but poor risk conferred by the cytogenetic aberrations is not completely abrogated. Altogether, daratumumab-based regimens have high anti-MM activity and a favorable toxicity profile and therefore represent new standards of care for patients with NDMM.

Delaying the use of high-dose melphalan with stem cell rescue in multiple myeloma is ready for prime time.
    Clinical advances in hematology & oncology : H&O, 2019, Volume: 17, Issue:10

    The significant advances made in the treatment of multiple myeloma (MM) have allowed for a paradigm shift away from the early use of high-dose melphalan with autologous stem cell transplant (HDM-ASCT). In 2015 alone, the US Food and Drug Administration (FDA) approved 4 novel drugs for MM. Novel drugs and regimens have shown unprecedented efficacy, which has increased the tempo of new drug development. Furthermore, the FDA recently approved a diagnostic test to detect minimal residual disease (MRD) that will allow community clinicians to conduct real-time testing of MRD. Most importantly, frontline regimens based on immunomodulatory drugs (IMiDs) and proteasome inhibitors (PIs) have shown a large clinical benefit. The next era has begun, as several 4-drug combinations that include monoclonal antibodies are being evaluated in clinical trials in the attempt to replace HDM-ASCT in the treatment of MM. We and others have therefore questioned the need for early HDM-ASCT, especially in light of the possible complications. HDM-ASCT is associated not only with acute toxicities-cytopenia, infection, and even death-but also an increased risk of developing secondary cancers. This article discusses the historic context of HDM-ASCT, the modern role of HDM-ASCT given the availability of highly sensitive MRD testing, and the likely future of quadruplet treatment. In summary, patients who attain deep responses using IMiD- and PI-based regimens may not require early HDM-ASCT. A delayed approach to this treatment is acceptable, and might be preferred by patients.

A meta-analysis of autologous transplantation for newly diagnosed multiple myeloma in the era of novel agents.
    Leukemia & lymphoma, 2019, Volume: 60, Issue:6

    To evaluate the role of high-dose melphalan plus autologous stem-cell transplantation (ASCT) as consolidation therapy for patients with newly diagnosed multiple myeloma (NDMM) in the era of novel agents, we undertook this meta-analysis. Medline, Embase, the Cochrane controlled trials register, the SCI, ASH, EHA, and ASCO were searched for clinical trials including high-dose chemotherapy plus ASCT for patients with NDMM. Finally, we identified four RCTs of ASCT versus novel agents based consolidations, and 10 single-arm prospective trials of ASCT alone. Pooled analysis indicated that response quality improved further after ASCT in the era of novel agents (≥CR rates of 13% pre-ASCT versus 29% post-ASCT,

Prevention of chemotherapy-induced nausea and vomiting after high-dose melphalan and stem cell transplantation: review of the evidence and suggestions.
    Supportive care in cancer : official journal of the Multinational Association of Supportive Care in Cancer, 2019, Volume: 27, Issue:3

    High-dose melphalan (HDMel) is the most common conditioning chemotherapy regimen for autologous stem cell transplantation (SCT) in patients affected by multiple myeloma (MM). No consensus exists for the emetogenicity or prophylaxis of chemotherapy-induced nausea and vomiting (CINV) in this regimen.. Data on the incidence and efficacy/safety of CINV prophylaxis among patients affected by MM undergoing autologous SCT with the HDMel regimen was extracted from electronic databases and analyzed.. Eleven studies involving multiple CINV prophylaxis regimens were identified and included. No consensus on HDMel emetogenicity was reached, but most studies summarized the emetogenicity as moderate-high risk. An aprepitant-based three-drug regimen (aprepitant + serotonin receptor antagonist (5HT3RA) + dexamethasone) showed better efficacy than a two-drug regimen (5HT3RA + dexamethasone) for CINV prevention without increasing the frequency in adverse events.. The aprepitant-based three-drug regimen should be the regimen of choice for CINV prophylaxis for MM patients undergoing autologous SCT with HDMel conditioning.

Efficacy of first-line treatments for multiple myeloma patients not eligible for stem cell transplantation: a network meta-analysis.
    Haematologica, 2019, Volume: 104, Issue:5

    Decision making for patients with multiple myeloma (MM) not transplant eligible (NTE) is complicated by a lack of head-to-head comparisons of standards of care, the increase in the choice of treatment modalities, and the promising results that are rapidly evolving from studies with novel regimens. To support evidence-based decision making, we performed a network meta-analysis for NTE MM patients that synthesizes direct and indirect evidence and enables a comparison of all treatments. Relevant randomized clinical trials were identified by a systematic literature review in EMBASE®, MEDLINE®, MEDLINE®-in-Process and the Cochrane Central Register of Controlled Trials for January 1999 to March 2016. Efficacy outcomes [i.e. the hazard ratio (HR) and 95% confidence interval (95%CI) for progression-free survival] were extracted and synthesized in a random effects network-meta analysis. In total, 24 studies were identified including 21 treatments. According to the network-meta analysis, the HR for progression-free survival was favorable for all NTE MM treatments compared to dexamethasone (HR: 0.19-0.90). Daratumumab-bortezomib-melphalan-prednisone and bortezomib-melphalan-prednisone-thalidomide with bortezomib-thalidomide maintenance were identified as the most effective treatments (HR: 0.19, 95%CI: 0.08-0.45 and HR: 0.22, 95%CI: 0.10-0.51, respectively). HR and 95%CI for currently recommended treatments, bortezomib-lenalidomide-dexamethasone, bortezomib-melphalan-prednisone, and lenalidomide-dexamethasone compared to dexamethasone, were 0.31 (0.16-0.59), 0.39 (0.20-0.75), and 0.44 (0.29-0.65), respectively. In addition to identifying the most effective treatment options, we illustrate the additional value and evidence of network meta-analysis in clinical practice. In the current treatment landscape, the results of network meta-analysis may support evidence-based decisions and ultimately help to optimize treatment and outcomes of NTE MM patients.

Therapy-related myeloid neoplasms after treatment for plasma-cell disorders.
    Best practice & research. Clinical haematology, 2019, Volume: 32, Issue:1

    Therapy-related myeloid neoplasms (t-MN), including therapy-related acute myeloid leukaemia and myelodysplastic syndrome, are second primary malignancies (SPM) that are of growing importance as patients with plasma cell disorders (PCD) such as multiple myeloma (MM) are living longer with more effective therapies. Both patient-specific and treatment-specific factors likely impact the risk of t-MN development after diagnosis and treatment of PCD. Alkylating chemotherapy, especially melphalan, has been strongly tied to the risk of t-MN. More recently, there has been a shift away from long-term alkylating therapies to immunomodulatory agents and high-dose therapy with autologous stem cell transplant (HD-ASCT). This shift has led to improved survival and long-term outcomes for most MM patients. However, the risks of t-MN remain despite the improved efficacy of these treatments, and patients who develop t-MN have a poor prognosis. Understanding the risk factors predisposing MM patients to t-MN can thus help to tailor individualized therapy to maximize anti-myeloma efficacy and minimize the risks of t-MN.

Treatment Outcomes in Patients With Newly Diagnosed Multiple Myeloma Who Are Ineligible for Stem-Cell Transplantation: Systematic Review and Network Meta-analysis.
    Clinical lymphoma, myeloma & leukemia, 2019, Volume: 19, Issue:8

    Many new regimens have been applied to newly diagnosed transplant-ineligible multiple myeloma, but no head-to-head research has been performed to compare the efficacy of these treatments. Currently lenalidomide plus dexamethasone (Rd) is one of the standard treatments. Our aim was to make a comparison of these treatments to Rd by a network meta-analysis. We performed a systematic review and network meta-analysis. We searched PubMed, Embase, and the Cochrane Library for articles published from January 1, 1988, to April 26, 2018, as well as research presented at 5 international conferences (American Society of Clinical Oncology, American Society of Hematology, European Hematology Association, European Society of Medical Oncology, and International Myeloma Working Group) between January 2015 and December 2018. Our interest outcomes were hazard ratios (HRs) for progression-free survival (PFS) and overall survival (OS). Bayesian fixed-effects mixed-treatment comparisons were used for this study. A total of 23 articles describing 10,401 participants were included for this network meta-analysis. Lenalidomide and dexamethasone plus daratumumab (HR, 0.57; 95% credible interval [CrI], 0.43-0.73), daratumumab plus bortezomib, melphalan, and prednisone (HR, 0.59; 95% CrI, 0.36-0.91), and the combination of bortezomib with lenalidomide and dexamethasone (RVd) (HR, 0.72, 95% CrI, 0.56-0.90) all showed significant effect compared to Rd for PFS. RVd demonstrated significant benefit compared to Rd (HR, 0.72; 95% CrI, 0.53-0.96) for OS. Our study results suggested that lenalidomide and dexamethasone plus daratumumab; daratumumab plus bortezomib, melphalan, and prednisone; and RVd showed better efficacy than Rd in PFS; and RVd showed better efficacy than Rd in OS in patients with newly diagnosed transplant-ineligible multiple myeloma in the absence of head-to-head research.

Melphalan hydrochloride for the treatment of multiple myeloma.
    Expert opinion on pharmacotherapy, 2017, Volume: 18, Issue:11

    Multiple myeloma (MM) is an incurable disease characterized by clonal plasma cell proliferation and overproduction of monoclonal paraprotein, hypercalcemia, renal failure, anemia, osteolytic bone lesions, and infections. Melphalan, a nitrogen mustard, is an alkylating agent synthesized in 1953, and it has been used in multiple myeloma therapy for fifty years. Although novel agents have been introduced in the past few decades improving prognosis of the disease, melphalan still maintains a crucial role in the treatment of MM acting both as cytotoxic agent through damage to DNA, and as immunostimulatory drug by inhibiting Interleukin-6, as well as interaction with dendritic cells, and immunogenic effects in tumor microenvironment. Areas covered: This review focuses on available data about melphalan pharmacology and its role in clinical practice. Expert opinion: Melphalan remains crucial in therapy of multiple myeloma because of its good manageability, safety profile, efficacy, and economic sustainability. These characteristics make it pivotal also for new regimens in combination with novel agents.

Fixed duration vs continuous therapy in multiple myeloma.
    Hematology. American Society of Hematology. Education Program, 2017, 12-08, Volume: 2017, Issue:1

    The introduction of new drugs with less severe toxicity profiles than those of conventional antimyeloma agents allowed the evaluation of continuous therapy compared with fixed duration therapy. In transplant-eligible patients, consolidation therapy with bortezomib or bortezomib-based regimens showed significant progression-free survival (PFS) benefit in cytogenetic standard-risk patients and to a lesser extent, high-risk patients. Continuous therapy with lenalidomide maintenance treatment after autologous stem cell transplantation resulted in a significant survival gain. In transplant noneligible patients, continuous lenalidomide-dexamethasone therapy improved survival over fixed duration melphalan-prednisone-thalidomide. The concept of prolonged treatment in elderly patients is supported by some other studies, but most of them revealed a gain in PFS only. Young patients with unfavorable prognosis show a greater willingness to accept long-term treatment, whereas the readiness to undergo such treatments and the benefits therefrom decline with increasing age and decreasing fitness, rendering fixed duration therapy a suitable option in elderly frail patients.

Management of multiple myeloma in the newly diagnosed patient.
    Hematology. American Society of Hematology. Education Program, 2017, 12-08, Volume: 2017, Issue:1

    Multiple myeloma is the second most frequent hematological disease. The introduction of melphalan as high-dose therapy followed by autologous hematopoietic cell transplantation (HDT/ASCT) for young patients and the availability of novel agents for young and elderly patients with multiple myeloma have dramatically changed the perspective of treatment. However, further research is necessary if we want definitively to cure the disease. Treatment goals for transplant-eligible and non-transplant-eligible patients should be to prolong survival by achieving the best possible response while ensuring quality of life. For young patients, HDT-ASCT is a standard of care for treatment, and its efficacy has been enhanced and challenged by the new drugs. For elderly patients, treatment options were once limited to alkylators, but new upfront treatment combinations based on novel agents (proteasome inhibitors and immunomodulatory drugs) combined or not with alkylators have significantly improved outcomes. Extended treatment of young and elderly patients improves the quality and duration of clinical responses; however, the optimal scheme, appropriate doses, and duration of long-term therapy have not yet been fully determined. This review summarizes progress in the treatment of patients with newly diagnosed multiple myeloma, addressing critical questions such as the optimal induction, early vs late ASCT, consolidation and/or maintenance for young patients, and how we can choose the best treatment option for non-transplant-eligible patients.

Better therapy requires better response evaluation: Paving the way for minimal residual disease testing for every myeloma patient.
    Cytometry. Part B, Clinical cytometry, 2016, Volume: 90, Issue:1

    In 2015, there is a large body of evidence demonstrating that minimal residual disease (MRD) negativity after therapy is a powerful predictor of progression-free survival and overall survival in multiple myeloma. On the basis of available data, we believe MRD provides a meaningful endpoint for regulatory purposes, academic studies, and a valuable prognostic evaluation of individual patients in the clinical setting. Similar to what has been shown in acute and chronic lymphocytic leukemia, based on emerging data, the prognostic impact of MRD in multiple myeloma appears to be independent of induction therapy received. This fact raises fundamental questions regarding best possible treatment strategies (e.g., fixed number of cycles versus response adapted number of cycles) as well as optimal treatment modalities (e.g., newer effective but less intense combination therapies versus high dose melphalan followed by autologous stem cell transplantation), in particular for patients newly diagnosed with multiple myeloma.

First-line therapy for non-transplant eligible patients with multiple myeloma: direct and adjusted indirect comparison of treatment regimens on the existing market in Germany.
    European journal of clinical pharmacology, 2016, Volume: 72, Issue:3

    The purpose of this study was to compare approved first-line therapies for patients with multiple myeloma.. A systematic literature search for phase III randomized controlled trials (RCTs) comparing first-line chemotherapies approved in Germany and recommended by guidelines at the time of study design was conducted. Random-effects meta-analysis (MA) was used for direct and the Bucher method for adjusted indirect treatment comparison.. One RCT comparing melphalan and prednisone plus bortezomib (VMP) vs. melphalan and prednisone (MP) and six RCTs comparing MP plus thalidomide (MPT) vs. MP were analysed. For MPT vs. MP, an individual patient data (IPD) MA was used for sensitivity analyses. VMP and MPT were superior to MP regarding efficacy endpoints (VMP vs. MP, overall survival (OS): hazard ratio (HR) 0.70, 95 % confidence interval (CI) 0.57-0.86; progression-free survival (PFS): HR 0.56, 0.39-0.79; complete response (CR), risk-ratio (RR) for non-response: 0.70, 0.65-0.75; MPT vs.. HR 0.83, 0.66-1.03; PFS: HR 0.67, 0.56-0.81; CR, RR for non-response 0.92, 0.88-0.95); but had a higher risk of developing any grade 3-4 adverse events (AEs) (VMP vs. MP: RR 1.13, 1.06-1.20; MPT vs. MP: RR 2.06, 1.43-2.98). The indirect comparison of VMP vs. MPT via MP showed a statistically not significant advantage for VMP regarding survival outcomes (OS: HR 0.85, 0.63-1.14; PFS: HR 0.83, 0.56-1.23) and a significant advantage regarding CR (RR for non-response 0.76, 0.70-0.83) and AEs (RR 0.55, 0.38-0.80). Treatment comparisons using results of IPD MA yielded similar effect sizes.. VMP and MPT seem more effective than MP, VMP was superior to MPT regarding response criteria and AEs. Our results may best be confirmed by a head-to-head trial of VMP vs. MPT.

Thalidomide-based Regimens for Elderly and/or Transplant Ineligible Patients with Multiple Myeloma: A Meta-analysis.
    Chinese medical journal, 2016, Feb-05, Volume: 129, Issue:3

    Thalidomide is an immunomodulatory and anti-angiogenic drug that has shown promise in patients with myeloma. Trials comparing efficacy of standard melphalan and prednisone (MP) therapy with MP plus thalidomide (MPT) in transplant-ineligible or elderly patients with multiple myeloma (MM) have provided conflicting evidence. This meta-analysis aimed to determine the efficacy and toxicity of thalidomide in previously untreated elderly patients with myeloma.. Medline, the Cochrane Controlled Trials register, conference proceedings of the American Society of Hematology (1995-2014), the American Society of Clinical Oncology (1995-2014), and CBM, VIP, and CNKI databases were searched for randomized control trials with the use of the medical subject headings "MM " and "thalidomide ". Trials were assessed by two reviewers for eligibility. Meta-analysis was conducted using a fixed effects model. Sensitivity analysis was performed to test the robustness of the findings.. Overall, seven trials were identified, covering a total of 1821 subjects. The summary hazard ratio (thalidomide vs. control) was 0.82 (95% confidence interval [CI]: 0.72-0.94) for overall survival (OS), and 0.65 (95% CI: 0.58-0.73) for progression-free survival, in favor of thalidomide treated group. The risk ratio of complete response with induction thalidomide was 3.48 (95% CI: 2.24-5.41). A higher rate of III/IV adverse events were observed in MPT arm compared with the MP arm. However, analysis of sub-groups administering anticoagulation as venous thromboembolism prophylaxis suggested no difference in relative risk of thrombotic events between two arms (RR = 1.47, 95% CI: 0.43-5.07, P = 0.54). Further analysis of trials on the treatment effects of MPT versus MP on adverse events-related mortality showed no statistical difference between two arms (RR = 1.24, 95% CI: [0.95-1.63], P = 0.120).. Thalidomide appears to improve the OS of elderly and/or transplant-ineligible patients with MM when it is added to standard MP therapy.

The role of high-dose melphalan and autologous stem cell transplant in the rapidly evolving era of modern multiple myeloma therapy.
    Clinical advances in hematology & oncology : H&O, 2016, Volume: 14, Issue:9

    The advent of the immunomodulatory drugs thalido-mide, lenalidomide, and pomalidomide; the proteasome inhib-itors bortezomib, carfilzomib, and ixazomib; the histone deacet-ylase inhibitor panobinostat; and the monoclonal antibodies elotuzumab and daratumumab has led to dramatic improvements in outcomes for patients with multiple myeloma. Along with progress in nontransplant therapy have come questions regarding the continued role of high-dose melphalan (HDM) supported by autologous stem cell transplant (ASCT) in the treatment of multiple myeloma. Emerging evidence from phase 3 studies demonstrates that consolidation therapy with HDM/ASCT further improves depth of response and progression-free survival in the context of modern therapy for multiple myeloma. Moreover, unprecedented survival data from ongoing phase 3 studies of patients treated with modern myeloma therapy followed by HDM/ASCT in first-line or second-line therapy reaffirm single and tandem HDM/ASCT as important standards of care for eligible patients. Herein, we review the evolving role of HDM/ASCT for the treatment of patients with newly diagnosed or relapsed multiple myeloma.

Myeloma: management of the newly diagnosed high-risk patient.
    Hematology. American Society of Hematology. Education Program, 2016, Dec-02, Volume: 2016, Issue:1

    Although there have been many definitions for high-risk (HR) myeloma, most recent consensus for classifying risk in patients with newly diagnosed multiple myeloma (NMM) comes from the International Myeloma Working Group. This recently published revised International Staging System includes del(17p) or t(4;14) by fluorescence in situ hybridization, β-2 microglobulin, albumin, and lactate dehydrogenase. These elements should be captured in all NMM patients. The optimal treatments for HR myeloma have not been fully worked out; therefore, these patients should be considered for clinical trials. Outside of the trial setting for those patients who are not eligible for autologous stem cell transplantation (ASCT), a regimen with bortezomib, but not thalidomide, should be considered, with a duration of therapy of at least 1 year. The regimen with the best results to date is bortezomib, melphalan, and predisone. A nonthalidomide maintenance could also be considered. In patients who are eligible for ASCT, an induction regimen with bortezomib and an immunomodulatory drug should be administered for 3 to 6 months followed by 2 ASCTs. Finally, a consolidation/maintenance regimen containing at least 1 year of bortezomib should be administered followed by maintenance thereafter. For patient convenience, an oral agent that is not thalidomide could be prescribed as maintenance. Finally, in patients with HR myeloma, allogeneic SCT may be associated with reasonable outcomes, but this too will require further research.

Managing multiple myeloma in the over 70s: a review.
    Maturitas, 2015, Volume: 80, Issue:2

    Multiple myeloma (MM) remains an incurable malignancy. Approximately 37% of patients with plasma cell myeloma are over the age of 75 and the median age of diagnosis is 70. The management approach to over 70s differs from younger patients, as treatment goals may vary and underlying co-morbidities and expected treatment related toxicities have to be taken into account. Individualisation of management is important, aiming to achieve the best response whilst minimising adverse events. A proportion of patients will be unable to tolerate any treatment with palliation being appropriate. Age alone should not be a barrier to treatment however, with some fit patients over the age of 70 potentially benefitting from intensive treatment options including high dose chemotherapy with autologous stem cell rescue. Comprehensive geriatric assessment is indicated in the over 70s; this should be employable in a clinic outpatient setting to make it feasible. Outcomes of this assessment potentially help physicians' choice of therapy. For decades the combination of Melphalan and prednisolone was the standard of care for older MM patients. Over the last ten years, newer drugs and combinations have improved therapeutic options for patients but are yet to demonstrate vast improvement in overall survival in this cohort.

Front-line lenalidomide therapy in patients with newly diagnosed multiple myeloma.
    Future oncology (London, England), 2015, Volume: 11, Issue:11

    The availability of novel drugs with different and innovative mechanisms of action such as proteasome inhibitors such as bortezomib and immunomdulatory agents as thalidomide and lenalidomide have changed the landscape of the treatment of patients with newly diagnosed multiple myeloma, allowing the development of several new therapeutic regimens both for transplant-eligible and -ineligible patients. Among these new agents, lenalidomide has become one of the most commonly used in these patients. In this article, we review the current state-of-the-art of different induction and maintenance lenalidomide-containing regimens administered in transplant-eligible and -ineligible patients with newly diagnosed multiple myeloma. We also discuss the safety profile and potential long-term side effects of this drug and analyze its utility in certain subgroups of patients like those with high-risk disease or different degrees of renal impairment.

Lenalidomide: a review of its continuous use in patients with newly diagnosed multiple myeloma not eligible for stem-cell transplantation.
    Drugs & aging, 2015, Volume: 32, Issue:5

    Lenalidomide (Revlimid(®)) is a second-generation immunomodulatory drug structurally related to thalidomide, with improved efficacy and tolerability, for which the label in the EU was recently expanded to include continuous therapy in patients with previously untreated multiple myeloma not eligible for stem-cell transplantation. In randomized, controlled clinical trials, continuous lenalidomide therapy, either in combination with dexamethasone (FIRST trial) or as maintenance monotherapy following induction with melphalan/prednisone/lenalidomide (MM-015 trial), significantly improved progression-free survival (PFS) compared with induction therapy alone (with non-lenalidomide- or lenalidomide-containing regimens) in patients with newly diagnosed multiple myeloma not eligible for stem-cell transplantation. The improvements in PFS with continuous lenalidomide were reflected in improved health-related quality-of-life measures. An overall survival benefit was observed in the FIRST trial, but not in the MM-015 trial. Continuous lenalidomide and continuous thalidomide regimens displayed similar efficacy, but lenalidomide was associated with significantly less toxicity than thalidomide. Continuous use of lenalidomide did not appear to negatively impact on the drug's tolerability and did not increase the incidence of neutropenia or second primary malignancy compared with shorter-term use. The incidence of most adverse events began to reduce after about 18 months of therapy. In conclusion, continuous lenalidomide regimens provide an effective longer-term treatment option in patients with newly diagnosed multiple myeloma ineligible for stem-cell transplantation.

[Successful treatment of relapsed and refractory multiple myeloma by using clarithromycin-lenalidomide, low-dose dexamethasone(BiRd), and melphalan-prednisolone(MP)].
    Gan to kagaku ryoho. Cancer & chemotherapy, 2015, Volume: 42, Issue:5

    The development of novel agents has markedly improved the prognosis of multiple myeloma(MM). However, salvage therapies for patients with MM that is refractory to novel agents and conventional chemotherapies have not been established. Herein, we describe successful treatments for such patients with the combination of clarithromycin, lenalidomide, and lowdose dexamethasone(BiRd)with or without melphalan and prednisolone(MP). Although its duration was relatively short, the remission is important in terms of the salvage strategy until the second generation of novel agents becomes available.

Treatment for patients with newly diagnosed multiple myeloma in 2015.
    Blood reviews, 2015, Volume: 29, Issue:6

    Multiple myeloma is the second most frequent haematological disease. The introduction of high-dose melphalan followed by autologous haematopoietic cell transplant (HDT/ASCT) for young patients and the availability of novel agents for young and elderly patients with multiple myeloma have dramatically changed the perspective of treatment. However, further research is necessary if we want to definitively cure the disease. Treatment goals for transplant-eligible and non-transplant-eligible patients should be to prolong survival by achieving the best possible response, while ensuring quality of life. The treatment should be individualized on the basis of host and disease features and better monitoring of the response upon use of high-sensitivity techniques for evaluating residual disease. For young patients, HDT/ASCT is a standard of care for treatment and its efficacy has been enhanced and challenged by the new drugs. For elderly patients, treatment options were limited to alkylators, but new upfront treatment combinations based on novel agents (proteasome inhibitors and immunomodulatory drugs) combined or not with alkylators have significantly improved outcomes.Extended treatment for young and elderly patients improves the quality and duration of clinical responses; however,the optimal scheme, appropriate doses and duration of long-term therapy have not yet been fully determined.This review summarises the progress in the treatment of patients with newly diagnosed multiple myeloma, addressing critical questions such as the optimal induction, early versus late ASCT, consolidation and/or maintenance for young patients, and how we can choose the best option for non-transplant-eligible patients.

Autologous haematopoietic cell transplantation in elderly patients with multiple myeloma.
    British journal of haematology, 2015, Volume: 171, Issue:4

    High-dose chemotherapy with melphalan followed by autologous haematopoietic cell transplantation (AHCT) is a standard of care in young patients (<65 years) with multiple myeloma. Most myeloma patients, however, are older than 65 years at the time of diagnosis, and the findings of numerous single-centre and registry studies provide evidence that AHCT can be a feasible and effective treatment option in these patients. Nevertheless, AHCT is not generally recommended as standard treatment in the elderly, due to the fact that a benefit of AHCT over conventional-dose therapy has not been demonstrated by prospective randomized trials. Yet, the use of AHCT has increased substantially in older patients in recent years, and an increasing number of reports suggest comparable outcomes for older and younger patients after AHCT. In this review we summarize the results of AHCT for elderly patients with multiple myeloma.

Maintenance therapy for multiple myeloma in the era of novel agents.
    Hematology. American Society of Hematology. Education Program, 2015, Volume: 2015

    Despite many recent advances in the treatment of multiple myeloma, the course of the disease is characterized by a repeating pattern of periods of remission and relapse as patients cycle through the available treatment options. Evidence is mounting that long-term maintenance therapy may help suppress residual disease after definitive therapy, prolonging remission and delaying relapse. For patients undergoing autologous stem cell transplantation (ASCT), lenalidomide maintenance therapy has been shown to improve progression-free survival (PFS); however, it is still unclear whether this translates into extended overall survival (OS). For patients ineligible for ASCT, continuous therapy with lenalidomide and low-dose dexamethasone was shown to improve PFS and OS (interim analysis) compared with a standard, fixed-duration regimen of melphalan, prednisone, and thalidomide in a large phase 3 trial. Other trials have also investigated thalidomide and bortezomib maintenance for ASCT patients, and both agents have been evaluated as continuous therapy for those who are ASCT ineligible. However, some important questions regarding the optimal regimen and duration of therapy must be answered by prospective clinical trials before maintenance therapy, and continuous therapy should be considered routine practice. This article reviews the available data on the use of maintenance or continuous therapy strategies and highlights ongoing trials that will help to further define the role of these strategies in the management of patients with newly diagnosed multiple myeloma.

Second primary malignancies with lenalidomide therapy for newly diagnosed myeloma: a meta-analysis of individual patient data.
    The Lancet. Oncology, 2014, Volume: 15, Issue:3

    Lenalidomide has been linked to second primary malignancies in myeloma. We aimed to pool and analyse available data to compare the incidence of second primary malignancies in patients with and without lenalidomide exposure.. We identified relevant studies through a search of PubMed and abstracts from the American Society of Clinical Oncology, American Society of Hematology, and the International Myeloma Workshop. Randomised, controlled, phase 3 trials that recruited patients with newly diagnosed multiple myeloma between Jan 1, 2000, and Dec 15, 2012, and in which at least one group received lenalidomide were eligible for inclusion. We obtained individual patient data (age, sex, date of diagnosis, allocated treatment and received treatment, duration of treatment and cause of discontinuation, maintenance treatment, date of first relapse, date of second primary malignancy diagnosis, type of second primary malignancy, date of death or last contact, and cause of death) by direct collaboration with the principal investigators of eligible trials. Primary outcomes of interest were cumulative incidence of all second primary malignancies, solid second primary malignancies, and haematological second primary malignancies, and were analysed by a one-step meta-analysis.. We found nine eligible trials, of which seven had available data for 3254 patients. 3218 of these patients received treatment (2620 had received lenalidomide and 598 had not), and were included in our analyses. Cumulative incidences of all second primary malignancies at 5 years were 6·9% (95% CI 5·3-8·5) in patients who received lenalidomide and 4·8% (2·0-7·6) in those who did not (hazard ratio [HR] 1·55 [95% CI 1·03-2·34]; p=0·037). Cumulative 5-year incidences of solid second primary malignancies were 3·8% (95% CI 2·7-4·9) in patients who received lenalidomide and 3·4% (1·6-5·2) in those that did not (HR 1·1 [95% CI 0·62-2·00]; p=0·72), and of haematological second primary malignancies were 3·1% (95% CI 1·9-4·3) and 1·4% (0·0-3·6), respectively (HR 3·8 [95% CI 1·15-12·62]; p=0·029). Exposure to lenalidomide plus oral melphalan significantly increased haematological second primary malignancy risk versus melphalan alone (HR 4·86 [95% CI 2·79-8·46]; p<0·0001). Exposure to lenalidomide plus cyclophosphamide (HR 1·26 [95% CI 0·30-5·38]; p=0·75) or lenalidomide plus dexamethasone (HR 0·86 [95% CI 0·33-2·24]; p=0·76) did not increase haematological second primary malignancy risk versus melphalan alone.. Patients with newly diagnosed myeloma who received lenalidomide had an increased risk of developing haematological second primary malignancies, driven mainly by treatment strategies that included a combination of lenalidomide and oral melphalan. These results suggest that alternatives, such as cyclophosphamide or alkylating-free combinations, should be considered instead of oral melphalan in combination with lenalidomide for myeloma..

Human B-cell cancer cell lines as a preclinical model for studies of drug effect in diffuse large B-cell lymphoma and multiple myeloma.
    Experimental hematology, 2014, Volume: 42, Issue:11

    Drug resistance in cancer refers to recurrent or primary refractory disease following drug therapy. At the cellular level, it is a consequence of molecular functions that ultimately enable the cell to resist cell death-one of the classical hallmarks of cancer. Thus, drug resistance is a fundamental aspect of the cancer cell phenotype, in parallel with sustained proliferation, immortality, angiogenesis, invasion, and metastasis. Here we present a preclinical model of human B-cell cancer cell lines used to identify genes involved in specific drug resistance. This process includes a standardized technical setup for specific drug screening, analysis of global gene expression, and the statistical considerations required to develop resistance gene signatures. The state of the art is illustrated by the first-step classical drug screen (including the CD20 antibody rituximab, the DNA intercalating topoisomerase II inhibitor doxorubicin, the mitotic inhibitor vincristine, and the alkylating agents cyclophosphamide and melphalan) along with the generation of gene lists predicting the chemotherapeutic outcome as validated retrospectively in clinical trial datasets. This B-cell lineage-specific preclinical model will allow us to initiate a range of laboratory studies, with focus on specific gene functions involved in molecular resistance mechanisms.

Not too little, not too much-just right! (Better ways to give high dose melphalan).
    Bone marrow transplantation, 2014, Volume: 49, Issue:12

    Of the 13 286 autologous haematopoietic cell transplant procedures reported in the US in 2010-2012 for plasma cell disorders, 10 557 used single agent, high-dose melphalan. Despite 30 years of clinical and pharmacokinetic (PK) experience with high-dose melphalan, and its continuing central role as cytoreductive therapy for large numbers of patients with myeloma, the pharmacodynamics and pharmacogenomics of melphalan are still in their infancy. The addition of protectant agents such as amifostine and palifermin allows dose escalation to 280 mg/m(2), but at these doses it is cardiac, rather than gut, toxicity that is dose-limiting. Although combination with additional alkylating agents is feasible, the additional TRM may not be justified when so many post-consolidation therapies are available for myeloma patients. Current research should optimise the delivery of this single-agent chemotherapy. This includes the use of newer formulations and real-time PKs. These strategies may allow a safe and effective platform for adding synergistic novel therapies and provide a window of lymphodepletion for the addition of immunotherapies.

Frontline Therapy for Patients with Multiple Myeloma not Eligible for Stem Cell Transplantation.
    Hematology/oncology clinics of North America, 2014, Volume: 28, Issue:5

    Considerable progress has been recently made in the treatment of elderly patients with multiple myeloma (MM). In Europe the combination of thalidomide with melphalan and prednisone and of bortezomib with melphalan and prednisone are 2 standards of care for frontline therapy for elderly patients. In United States the combination of lenalidomide and dexamethasone is the preferred option in this setting. This article focuses on more recent therapeutic approaches in older MM patients, not eligible for high-dose therapy and autologous stem cell transplantation.

Multiple myeloma.
    Hematology/oncology clinics of North America, 2014, Volume: 28, Issue:6

    Autologous stem cell transplant (ASCT) remains an integral part of the treatment strategy for many myeloma patients. The role of allogeneic stem cell transplant continues to be defined. There is increasing evidence that posttransplant maintenance therapy can significantly improve outcomes. It is predicted that with more routine use of cytogenetic and gene expression profiling in the future, we will be better able to identify those subgroups of patients who are expected to benefit most from early versus late versus no ASCT and those who will benefit from allogeneic stem cell transplant.

[Autopsy case of light chain deposition disease presented by nephrotic syndrome].
    Nihon Jinzo Gakkai shi, 2013, Volume: 55, Issue:1

    An eighty-one-year-old male with lower leg edema and proteinuria was diagnosed as having nephrotic syndrome and was hospitalized for a detailed examination. Kidney biopsy and immunostaining revealed nodular glomerulosclerosis and deposition of lambda chains, respectively. Because these findings indicate the occurrence of light chain deposition disease (LCDD), the underlying disease was found to be multiple myeloma BJ-lambda. After the administration of melphalan and prednisolone, followed by further addition of zoledronic acid, the patient's nephrosis remitted. However, renal dysfunction gradually deteriorated further and hemodialysis was instituted. He eventually died of gastrointestinal bleeding and biliary infection. The period of time from the initial diagnosis to death was thirty months. Autopsy revealed pervasive infiltration of plasma cells and light chain deposition in multiple organs. The uncontrollable gastrointestinal bleeding appears to have been caused by light chain deposition in the vascular walls of a bile duct. Although medical treatment for elderly LCDD cases depends on chemotherapy alone, it is difficult to obtain a complete remission with melphalan and prednisolone, according to the literature. Reports on the validities of biological agents, such as bortezomib, are beginning to appear, and accumulation of further therapeutic experience is eagerly awaited.

Addressing the questions of tomorrow: melphalan and new combinations as conditioning regimens before autologous hematopoietic progenitor cell transplantation in multiple myeloma.
    Expert opinion on investigational drugs, 2013, Volume: 22, Issue:5

    The role of high-dose chemotherapy (HDC) followed by autologous-progenitor cell transplantation (auto-HPCT) in the treatment of multiple myeloma (MM) continues to evolve in the novel agent era. Administration of high-dose melphalan (HDM) is considered the standard conditioning regimen. Nevertheless, several attempts have recently been made to improve the conditioning phase of the HDC procedure.. We reviewed all the reported experiences and illustrated current knowledge in the field of conditioning regimens.. For fit MM patients, HDC followed by auto-HPCT remains the standard of care. The available data confirm that melphalan (MEL) 200 mg/m(2) should continue to be considered the gold standard conditioning regimen, with dose reduction based on age and renal function. Targeting exposure to MEL by using area under the curve is a particularly appealing approach that could be explored to maximize efficacy and minimize toxicity of this drug. Other strategies are currently being evaluated in different trials, and the most interesting areas of research involve the incorporation of newer agents like bortezomib (BOR) into conditioning regimens. Moreover, intravenous busulfan has become available and this formulation may reduce toxicity and result in greater efficacy in association with MEL-based conditioning.

Efficacy and safety of busulfan-based conditioning regimens for multiple myeloma.
    The oncologist, 2013, Volume: 18, Issue:5

    Multiple myeloma is a malignancy of B cells characterized by accumulation of abnormal plasma cells in the bone marrow. In the past 20 years, the use of high-dose therapies and novel agents has resulted in significant and meaningful improvements in survival. Autologous stem cell transplantation (auto-SCT) following a high-dose melphalan-conditioning regimen represents the standard of care for younger patients as well as older patients with a good performance status. A number of strategies have been proposed to improve the outcome of auto-SCTs, including the incorporation of new agents such as thalidomide, lenalidomide, and bortezomib into the induction regimen administered before auto-SCT; the administration of maintenance therapy after auto-SCT; the incorporation of novel agents into chemotherapeutic regimens after transplantation as consolidation therapy; and the use of reduced-intensity allogeneic transplantation after an initial autograft. Although these approaches have demonstrated some success in improving responses after auto-SCT, none of these strategies are curative. An additional strategy to improve outcomes after auto-SCT is to enhance the immediate pretransplant conditioning regimens by either increasing the dose of melphalan or by incorporating novel agents, such as busulfan. This literature review focuses on the efficacy and safety of busulfan-based conditioning regimens for auto-SCT in patients with multiple myeloma.

Strategies for induction, autologous hematopoietic stem cell transplantation, consolidation, and maintenance for transplantation-eligible multiple myeloma patients.
    Hematology. American Society of Hematology. Education Program, 2013, Volume: 2013

    There have been major advances in the past decade in the continuum of therapy for transplantation-eligible multiple myeloma patients. For patients requiring therapy, recommended induction treatment consists of triple drug regimens followed by the collection of hematopoietic stem cells. The question of early versus delayed transplantation is under investigation and may identify patients for whom early transplantation is optimal therapy and those for whom it may be delayed. For transplantation-eligible patients, high-dose melphalan remains the standard regimen. After transplantation, consolidation can be considered for patients with less than a complete remission. Maintenance therapy with bortezomib or lenalidomide (or both in very-high-risk patients) is a reasonable option for long-term disease control and improvement in overall survival. Incorporation of new agents into the continuum of multiple myeloma care should result in improved outcomes and long-term disease control.

Evolving therapeutic paradigms for multiple myeloma: back to the future.
    Leukemia & lymphoma, 2013, Volume: 54, Issue:3

    Multiple myeloma (MM) is an ancient disease, but until the alkylating agent melphalan was found to have anti-myeloma properties in the 1950s there was virtually no effective therapy. By the late 1960s, extended dosing with melphalan and prednisone tripled survival from diagnosis and became the standard of care for newly diagnosed MM. "Maintenance therapy" to prolong survival through sustained disease control following induction chemotherapy was sought by 1970, but early strategies were ineffective and toxic. Subsequent applications of high-dose therapy (HDT)/autologous stem cell transplant (ASCT) changed the treatment paradigm for MM from extended dosing to an intensive strategy designed to eradicate the malignant cells in a single course of treatment. Although HDT-ASCT resulted in prolonged duration of remission and improved survival, the vast majority of patients still relapsed. Interferon (IFN) and glucocorticoid maintenance therapies demonstrated marginal improvements in outcomes but significant adverse effects. Novel agents introduced over the last decade have prolonged survival when given for maintenance following HDT-ASCT, but have also challenged the HDT-ASCT paradigm by achieving comparable remission rates when used alone as extended frontline therapy. This article reviews the evolution of therapeutic strategies for MM and discusses future questions facing MM investigators.

Fifty years of melphalan use in hematopoietic stem cell transplantation.
    Biology of blood and marrow transplantation : journal of the American Society for Blood and Marrow Transplantation, 2013, Volume: 19, Issue:3

    Melphalan remains the most widely used agent in preparative regimens for hematopoietic stem cell transplantation (SCT). From its initial discovery more than 50 years ago, it has been gradually incorporated in the conditioning regimens for both autologous and allogeneic transplantations because of its myeloablative properties and broad antitumor effects as a DNA alkylating agent. Melphalan remains the mainstay conditioning for multiple myeloma and lymphomas, and it has been used successfully in preparative regimens of a variety of other hematological and nonhematological malignancies. The addition of newer agents to conditioning, such as bortezomib or lenalidomide for myeloma or clofarabine for myeloid malignancies, may improve antitumor effects for transplantation, whereas melphalan in combination with alemtuzumab may represent a backbone for future cellular therapy because of reliable engraftment and low toxicity profile. This review summarizes the development and the current use of this remarkable drug in hematopoietic SCT.

Current therapeutic strategy for multiple myeloma.
    Japanese journal of clinical oncology, 2013, Volume: 43, Issue:2

    This is a review regarding the current therapeutic strategies in the management of multiple myeloma. Due to the introduction of several new effective therapeutic agents, multiple myeloma is one of the most active and changing fields in clinical oncology. Multiple myeloma is caused by the expansion of monoclonal plasma cells and secretion of M-protein (immunoglobulins, Bence Jones protein and free light chain). High-dose chemotherapy supported with autologous peripheral blood stem cells is an effective treatment for the disease. However, multiple myelomas are still difficult to cure and require long-term disease control. In recent years, the introduction of novel drugs (bortezomib, lenalidomide and thalidomide) has improved treatment.

Induction therapy for newly diagnosed multiple myeloma.
    Journal of the National Comprehensive Cancer Network : JNCCN, 2013, Jan-01, Volume: 11, Issue:1

    Treatment options for patients with newly diagnosed myeloma have evolved significantly over the past 10 years. Although response rates after induction for older or younger patients were limited, with few patients achieving complete remission, more recent combinations have cleared the way for major response and even complete remissions after induction therapy. As a consequence of these changes, patients are now achieving more durable and longer remissions, which have ultimately improved overall survival for patients with myeloma. The age-appropriate use of induction therapy, autologous transplant, and maintenance therapy, all keeping in mind the specific genetic risk group of a given patient, requires a long-term treatment plan for each patient defined early in the treatment course.

Part II: role of maintenance therapy in transplant-ineligible patients.
    Journal of the National Comprehensive Cancer Network : JNCCN, 2013, Jan-01, Volume: 11, Issue:1

    Many advances were made in the treatment of multiple myeloma since the introduction of the immunomodulatory drugs thalidomide and lenalidomide and the proteasome inhibitor bortezomib. An increasing number of clinical trials have examined consolidation/maintenance therapy as part of a sequential approach after induction therapy and demonstrated benefit in patients eligible and ineligible for transplantation. This outcome improvement reported with consolidation/maintenance therapy should be balanced against the toxicity profile, and prompt management of adverse events is necessary. This article provides an overview of the main trials including consolidation/maintenance therapy after induction for transplant-ineligible patients. Recommendations on how to manage treatment-related toxicities are also provided.

Multiple myeloma preparative regimens for high-dose therapy and autologous transplantation: what's new?
    Journal of comparative effectiveness research, 2012, Volume: 1, Issue:1

    High-dose chemotherapy and autologous stem cell transplantation remains a standard procedure in relatively young and selected older patients with multiple myeloma. High-dose melphalan has remained the chemotherapeutic agent of choice based on earlier prospective randomized trials. Despite investigations involving different combinations of chemotherapeutics, radiation and novel agents with and without melphalan, none of these alternative preparative regimens have demonstrated superiority to high-dose melphalan used as a single agent in multiple published studies. In this article, we review the published literature regarding preparative regimens used in patients with multiple myeloma undergoing autologous stem cell transplantation.

    Light-chain (AL) amyloidosis may present with features suggesting vasculitis, including giant-cell arteritis (GCA). We describe a case of an 80-year-old man, who initially presented with bilateral jaw claudication, bi-temporal headache and arthralgia, however a temporal-artery biopsy then revealed AL amyloidosis. A diagnosis of AL amyloidosis complicating multiple myelome simulates GCA and polymyalgia rheumatica was established. The patient was successfully treated with melphalan and dexamethasone: the free kappa light chains decreased, the patient's jaw claudication and headache disappeared. Then we discuss similarities between GCA and AL amyloidosis and potential confusion in diagnosis. We suggest that, in patients with clinical features of GCA without any temporal-artery typical findings, specimens are stained with Congo red, which then results in a different diagnosis and treatment.

Low dose cepharanthine ameliorates immune thrombocytopenic purpura associated with multiple myeloma.
    International immunopharmacology, 2012, Volume: 13, Issue:3

    Immune thrombocytopenic purpura associated with multiple myeloma is extremely rare. Here, we present the successful management of an elderly Japanese patient with multiple myeloma complicated by immune thrombocytopenia with low dose cepharanthine - a plant derived alkaloid. A 78-year-old male patient with IgGκ multiple myeloma was repetitively treated with melpharan and prednisolone. In each chemotherapy course, we demonstrated a close relationship between platelet recovery and administration of high dose prednisolone. When further chemotherapy was avoided because of the patient's poor general condition, administration of cepharanthine was effective in halting progressive thrombocytopenia due to abnormal immune mechanisms. We propose the usefulness of cepharanthine in management of this rare disease.

    Gastroenterologia y hepatologia, 2012, Volume: 35, Issue:8

    Drug-induced liver injury (DILI) is a leading cause of liver failure and an important safety issue in drug development. Thalidomide is nowadays used for the treatment of several conditions including multiple myeloma (MM). Several adverse effects have been described but liver toxicity was seldom reported. We describe a case of thalidomide-induced hepatitis in a man treated for MM. The clinical setting and temporal association between the start of the drug and liver injury allowed the assumption of the causative role of thalidomide. As its clinical indications expand we wish to increase awareness of a new potential side effect of thalidomide. A short review on thalidomide-induced liver injury is also presented.

Allogeneic hematopoietic stem cell transplantation for multiple myeloma: curative but not the standard of care.
    Current opinion in oncology, 2012, Volume: 24, Issue:6

    Despite the curative potential of allogeneic hematopoietic stem cell transplantation (allo HSCT) for patients with multiple myeloma, and reduction of transplant-related mortality with nonmyeloablative transplant approaches, rates of acute and chronic graft-versus-host disease and disease progression remain high. It is unclear if nonmyeloablative transplants are more effective than autologous (auto). Novel promising drugs and maintenance treatment strategies following auto SCT may also delay allo transplantation. In this review, we summarize the emerging data on allo HSCT and provide suggestions for its optimal role in the treatment of myeloma.. Large cooperative group studies comparing allo HSCT with auto SCT as frontline therapy have been performed with reduced intensity conditioning regimens using unmanipulated peripheral blood stem cells from human leukocyte antigen (HLA)-compatible donors and standard calcineurin inhibitor graft-versus-host disease prophylaxis. Two recent reports show conflicting data. Although the Blood and Marrow Transplant Clinical Trials Network 0102 study demonstrated no progression-free or overall survival advantage at 3 years, a European study demonstrated superior 5-year outcome after auto/HLA-matched sibling allo HSCT compared with tandem auto SCT in previously untreated multiple myeloma patients. The advent of maintenance therapy could potentially improve outcomes of both transplant types.. High rates of acute and chronic graft-versus-host disease currently limit the implementation of nonmyeloablative allo HSCT. Novel approaches are required so that patients with myeloma can undergo allo HSCT before resistance develops to standard drug combinations.

Diagnosis and treatment of multiple myeloma and AL amyloidosis with focus on improvement of renal lesion.
    Clinical and experimental nephrology, 2012, Volume: 16, Issue:5

    Multiple myeloma (MM) and AL amyloidosis are caused by the expansion of monoclonal plasma cells and secretion of dysproteinemia (Bence Jones protein and free light chain) and some patients require the hemodialysis. Myeloma kidney is mainly caused by the cast nephropathy of the distal tubuli, whereas, AL amyloid-protein is mainly deposited in glomeruli with massive fibrillar involvement. Therefore, almost MM patients presents a symptom of renal insufficiency, whereas, almost patients of AL amyloidosis present a nephrotic syndrome with severe hypoalbuminemia. These two diseases have some similar characteristics such as up-regulation of cyclin D1 gene by 11:14 chromosomal translocation. High-dose chemotherapy supported with autologous peripheral blood stem cells is effective for these two diseases. However, they are still difficult to be cured and require long-term disease control. In recent years, introduction of novel agents has changed their treatment strategies from the palliation therapy to the clinical cure.

Role of autologous bone marrow transplant in multiple myeloma.
    Current opinion in oncology, 2012, Volume: 24, Issue:6

    The treatment of newly diagnosed multiple myeloma has evolved rapidly over the recent years. In younger patients, autologous stem cell transplantation (ASCT) is still considered the standard of care, but the availability of new effective drugs with novel mechanisms of action in the last decade has resulted in a new scenario that has caused the role of transplantation itself to be currently undergoing scrutiny.. Maintaining the response of first-line therapy is an important objective in multiple myeloma, where despite intensive therapy followed by ASCT the majority of patients will relapse. In this field, the recent results of different consolidation and maintenance therapies after transplant are very encouraging. These strategies have come to stay and will play an essential role in the next future to improve the prognosis of young patients with newly diagnosed multiple myeloma. Finally, new conditioning regimens will also be tested in the forthcoming years in an attempt to further improve posttransplant responses.. Multiple myeloma ASCT must be integrated within a more global therapeutic approach including new and more effective induction, consolidation, and maintenance approaches. Efforts aimed in the development of more effective and less toxic preparative regimens to further augment disease control are also warranted.

Doublets, triplets, or quadruplets of novel agents in newly diagnosed myeloma?
    Hematology. American Society of Hematology. Education Program, 2012, Volume: 2012

    The treatment of multiple myeloma is evolving rapidly. A plethora of doublet, triplet, and quadruplet combinations have been studied for the treatment of newly diagnosed myeloma. Although randomized trials have been conducted comparing older regimens such as melphalan-prednisone with newer regimens containing drugs such as thalidomide, lenalidomide, or bortezomib, there are few if any randomized trials that have compared modern combinations with each other. Even in the few trials that have done so, definitive overall survival or patient-reported quality-of-life differences have not been demonstrated. Therefore, there is marked heterogeneity in how newly diagnosed patients with myeloma are treated around the world. The choice of initial therapy is often dictated by availability of drugs, age and comorbidities of the patient, and assessment of prognosis and disease aggressiveness. This chapter reviews the current data on the most commonly used and tested doublet, triplet, and quadruplet combinations for the treatment of newly diagnosed myeloma and provides guidance on choosing the optimal initial treatment regimen.

Multiple myeloma : recent progress in diagnosis and treatment.
    Journal of clinical and experimental hematopathology : JCEH, 2012, Volume: 52, Issue:3

    Multiple myeloma (MM) has been the most intractable hematological disease for many years. Recently, basic and clinical research has advanced remarkably and a new therapeutic strategy has been established. The introduction of high-dose melphalan with autologous stem-cell transplantation and the availability of molecular-targeted novel agents such as immunomodulatory drugs and proteasome inhibitors have dramatically changed the treatment strategies for MM. Achievement of a high response rate resulted in the extension of overall survival, but further research and the development of more multimodality therapeutic approaches is warranted to cure this disease.

Thalidomide versus bortezomib based regimens as first-line therapy for patients with multiple myeloma: a systematic review.
    American journal of hematology, 2011, Volume: 86, Issue:1

    Thalidomide (T) or bortezomib (B) in combination with melphalan plus prednisone (MP) is superior to MP as first line therapy for previously untreated myeloma. However, direct head-to-head comparison of Melphalan, Prednisone plus Bortezomib (MPB) versus Melphalan, Prednisone plus Thalidomide (MPT) is lacking. We performed an indirect meta-analysis to assess the treatment effects of MPB versus MPT via common comparator MP using the systematic review and meta-analytical techniques. A comprehensive literature search (MEDLINE and gray literature) was undertaken. Systematic review was performed as per the Cochrane Collaboration recommendations. Initial search yielded 1,013 citations, of which six randomized controlled trials (RCTs) enrolling 2,798 patients met the inclusion criteria. Comparison of MPT versus MP (five RCTs) showed no survival difference [hazard ratio (HR) 0.82, 95% confidence interval (CI) 0.64-1.05] but a statistically significant difference in event-free survival favoring MPT (HR 0.66, 95% CI 0.56-0.77) without excessive treatment-related mortality [risk ratio (RR) 1.11, 95% CI 0.64-1.92]. Comparison of MPB vs. MP (one RCT) showed a statistically significant benefit for survival (HR 0.65, 95% CI 0.51-0.84) and event-free survival (HR 0.48, 95% CI 0.37-0.63) without difference in treatment-related mortality (RR 0.42, 95% CI 0.11-1.63) with MPB. The indirect comparison of MPB versus MPT showed no difference between MPB versus MPT for all outcomes but a significant benefit for complete response (RR 2.34, 95% CI 1.12-4.90), and grade III/IV adverse events (RR 0.53, 95% CI 0.38-0.73) favoring MPB. There is an uncertainty about definitive superiority of one type of regimen over the other. Therefore, direct head-to-head comparison between these competing regimens is warranted.

Melphalan and prednisone versus melphalan, prednisone and thalidomide for elderly and/or transplant ineligible patients with multiple myeloma: a meta-analysis.
    Leukemia, 2011, Volume: 25, Issue:4

    Trials comparing efficacy of melphalan prednisone (MP) with MP plus thalidomide in transplant ineligible, elderly patients with multiple myeloma have provided conflicting evidence. Although there is agreement regarding improved response rates (RRs) and higher toxicity with the addition of thalidomide to MP, the impact on progression free survival (PFS) and overall survival (OS) is less clear. We performed a meta-analysis comparing efficacy of melphalan, prednisone and thalidomide (MPT) and MP by pooling results on RR, PFS and OS reported in all the identified randomized controlled trials (RCTs) under a random effects model. Overall, six prospective RCTs, with data extractable from five published trials (n=1571) [corrected] were identified. The pooled odds ratio of responding to therapy with MPT vs MP was 3.39 (P<0.001, 95% CI: 2.24-5.12). The pooled hazard ratios for PFS and OS were and 0.68 (P<0.001; 95% CI: 0.55-0.82) and 0.80 (P=0.07; 95% CI: 0.63-1.02), respectively, in favor of MPT. The odds ratios for high grade peripheral neuropathy and deep venous thrombosis were 6.6 and 2.4, respectively, in favour of MP. There was significant heterogeneity among the RCTs. Our meta-analysis demonstrates that in previously untreated, transplant ineligible, elderly myeloma patients, the addition of T to MP results in significantly improved RR and PFS with a trend towards improvement in OS compared with MP alone, but at a cost of significantly greater toxicity.

Treatment of newly diagnosed myeloma in patients not eligible for transplantation.
    Current hematologic malignancy reports, 2011, Volume: 6, Issue:2

    Melphalan plus prednisone (MP) has long been considered the gold-standard treatment for elderly patients with newly diagnosed myeloma, and it still forms the backbone for combinations based on novel agents. MP plus thalidomide (MPT), bortezomib (VMP), or lenalidomide (MPR), as induction plus maintenance, have proved to be superior to MP and are currently the treatment of choice for this population. Low-dose dexamethasone in combination with thalidomide and cyclophosphamide (CTDa) or with lenalidomide can be an alternative option for these patients. The benefit of these novel agents in terms of prolonged survival is accompanied by increases in treatment-related adverse events, however, which may be particularly pronounced in older individuals. In managing these patients, efficacy and toxicity should be balanced, and thus prophylactic measures to avoid adverse effects are mandatory. Moreover, reduced-intensity regimens are recommended for fragile or very elderly patients. Finally, the wide array of new treatment options will facilitate individualized treatment approaches, based on characteristics of the disease, patient comorbidities, and personal and social circumstances.

New developments in conditioning regimens before auto-SCT in multiple myeloma.
    Bone marrow transplantation, 2011, Volume: 46, Issue:7

    The current standard conditioning regimen before auto-SCT in patients with multiple myeloma is melphalan 200 mg/m(2). Several attempts have recently been made to improve this aspect of the high-dose therapy procedure. The scope of this review article is to summarize current knowledge on conditioning regimens in this setting.

Firstline treatment and maintenance in newly diagnosed multiple myeloma patients.

    High dose therapy (HDT) with autologous stem cell transplantation (ASCT) is the standard of care for eligible newly diagnosed MM patients. Several randomized studies demonstrated a survival advantage for patients undergoing transplantation, compared with conventional chemotherapy. Introduction of new drugs in this setting have markedly increased survival rates within the last 10 years. Efforts to further improve response rates and survival in those patients are still needed, mainly by increasing the depth of tumor reduction and the duration of response through more effective induction, consolidation and maintenance therapies. Nevertheless, this approach is currently challenged by the promising results of long-term treatment with novel agents. Recent data suggest that the upfront combination of a proteasome inhibitor plus one immunomodulatory drug (IMiD) is highly effective. The most promising 3-drug association might be Bortezomib, Lenalidomide and dexamethasone (VRD). Adjunction of a 4th drug is not proven to be more efficient. Consolidation and maintenance therapies are emerging in all trials with great results. For elderly patients, or not eligible for ASCT, the introduction of novel agents has also changed the management of the disease. Melphalan-prednisone-thalidomide and bortezomib-melphalan-prednisone are the two standards of care. Current trials are challenging the role of alkylators in the frontline setting. Maintenance therapy is also undergoing evaluation.

[New insights in the treatment of myeloma with renal failure].
    Nephrologie & therapeutique, 2011, Volume: 7, Issue:6

    Renal failure, mostly related to myeloma cast nephropathy (MCN), is a frequent complication of multiple myeloma (MM), which occurs in up to 50% of patients during the course of the disease. Persistent renal failure in MM is associated with poor survival. Treatment of MCN relies on urgent symptomatic measures (alkalinisation, rehydration, correction of hypercalcemia, and withdrawal of nephrotoxic drugs), with rapid introduction of chemotherapy to efficiently reduce the production of monoclonal light chains (LC). Recent studies suggest that, in patients with MM and severe renal failure due to MCN, rapid removal of circulating LC, through intensive hemodialysis sessions using a new generation high cut-off dialysis membrane, might result in dialysis withdrawal in most patients. If the development of intensive therapy and new efficient chemotherapy agents (thalidomide, bortezomib, lenalidomide) has transformed the care and prognosis of MM, the modalities and safety of these therapeutic regimens in patients with renal failure remain to be defined. The association of bortezomib with dexamethasone should be considered currently as first-line treatment in patients with MM and impaired renal function.

Thalidomide for previously untreated elderly patients with multiple myeloma: meta-analysis of 1685 individual patient data from 6 randomized clinical trials.
    Blood, 2011, Aug-04, Volume: 118, Issue:5

    The role of thalidomide for previously untreated elderly patients with multiple myeloma remains unclear. Six randomized controlled trials, launched in or after 2000, compared melphalan and prednisone alone (MP) and with thalidomide (MPT). The effect on overall survival (OS) varied across trials. We carried out a meta-analysis of the 1685 individual patients in these trials. The primary endpoint was OS, and progression-free survival (PFS) and 1-year response rates were secondary endpoints. There was a highly significant benefit to OS from adding thalidomide to MP (hazard ratio = 0.83; 95% confidence interval 0.73-0.94, P = .004), representing increased median OS time of 6.6 months, from 32.7 months (MP) to 39.3 months (MPT). The thalidomide regimen was also associated with superior PFS (hazard ratio = 0.68, 95% confidence interval 0.61-0.76, P < .0001) and better 1-year response rates (partial response or better was 59% on MPT and 37% on MP). Although the trials differed in terms of patient baseline characteristics and thalidomide regimens, there was no evidence that treatment affected OS differently according to levels of the prognostic factors. We conclude that thalidomide added to MP improves OS and PFS in previously untreated elderly patients with multiple myeloma, extending the median survival time by on average 20%.

The clinical effectiveness and cost-effectiveness of bortezomib and thalidomide in combination regimens with an alkylating agent and a corticosteroid for the first-line treatment of multiple myeloma: a systematic review and economic evaluation.
    Health technology assessment (Winchester, England), 2011, Volume: 15, Issue:41

    Multiple myeloma (MM) is the second most common haematological cancer in the UK. MM is not curable but can be treated with a combination of supportive measures and chemotherapy that aim to extend the duration and quality of survival. The majority of patients are not able to withstand intensive treatment, such as high-dose chemotherapy with autologous stem cell transplantation (SCT), and so they are offered single-agent or combination chemotherapy. Combination therapies typically include chemotherapy with an alkylating agent and a corticosteroid. More recently, combination therapies have incorporated drugs such as thalidomide (Thalidomide Celgene®, Celgene) and bortezomib (Velcade®, Janssen-Cilag).. To assess the clinical effectiveness and cost-effectiveness of bortezomib or thalidomide in combination chemotherapy regimens with an alkylating agent and a corticosteroid for the first-line treatment of MM.. Electronic bibliographic databases, including MEDLINE, EMBASE and The Cochrane Library, were searched from 1999 to 2009 for English-language articles. Bibliographies of articles, grey literature sources and manufacturers' submissions were also searched. Experts in the field were asked to identify additional published and unpublished references.. Titles and abstracts were screened for eligibility by two reviewers independently. The inclusion criteria specified in the protocol were applied to the full text of retrieved papers by one reviewer and checked independently by a second reviewer. Data extraction and quality assessment were undertaken by one reviewer and checked by a second reviewer. Differences in opinion were resolved through discussion at each stage. A cost-utility decision-analytic model was used to compare the cost-effectiveness estimates of bortezomib in combination with melphalan and prednisolone/prednisone (VMP), thalidomide in combination with cyclophosphamide and attenuated dexamethasone (CTDa), and thalidomide in combination with melphalan and prednisolone/prednisone (MPT) versus melphalan and prednisolone/prednisone (MP).. A total of 1436 records were screened and 40 references were retrieved for the systematic review of clinical effectiveness. Five randomised controlled trials (RCTs) met the inclusion criteria for the review: one RCT evaluated VMP, three evaluated MPT and one evaluated CTDa. The comparator in all of the included trials was MP. The review found that VMP and MPT can both be considered more clinically effective than MP for the first-line treatment of MM in people for whom high-dose therapy and SCT would not be appropriate. CTDa was more effective than MP in terms of complete response but data on survival outcomes did not meet the inclusion criteria. Cost-effectiveness analysis indicated that MPT has a greater probability of being cost-effective than either VMP or CTDa.. For most RCTs, details needed to judge study quality were incompletely reported. All studies stated that the analyses followed intention-to-treat principles but none adequately reported data censoring. Only one RCT contributed data on VMP and the published peer-reviewed follow-up data were immature. For MPT, overall survival data from two trials were eligible for inclusion but the doses of thalidomide differed between the trials and the treatment period was not reflective of current UK practice so the generalisability of the findings was uncertain. Two RCTs had a maintenance phase with thalidomide that did not meet the inclusion criteria so some of these results were not eligible for the review. Limited evidence on health-related quality of life (HRQoL) was provided by the single trial of VMP versus MP.. Service provision is unlikely to change greatly. As uncertainties remain, further research is needed regarding the use of bortezomib- and thalidomide-containing combination regimens. Head-to-head trials of bortezomib- and thalidomide-containing combination regimes are required, including assessments of patient HRQoL in response to treatment..

New treatments for myeloma.
    Joint bone spine, 2010, Volume: 77, Issue:1

    The management of multiple myeloma has benefited substantially from the introduction of three new drugs, namely, the proteasome inhibitor bortezomib and the immunomodulators thalidomide and lenalidomide. These drugs were initially shown to improve the outcome of advanced myeloma and were subsequently found to transform the treatment of patients with previously untreated myeloma. Melphalan and prednisone combined with thalidomide or bortezomib is the new treatment of reference for patients who are elderly or ineligible for intensification. The introduction of these new drugs into induction regimens, intensified conditioning regimens, and posttransplantation regimens may improve overall survival among young patients by increasing the rate and quality of the treatment responses. Although myeloma remains incurable, prolonged survival is now a reasonable objective.

New developments in the treatment of patients with multiple myeloma.
    The Netherlands journal of medicine, 2010, Volume: 68, Issue:1

    Much progress has been made in the treatment of patients with multiple myeloma (MM). The introduction of new drugs such as thalidomide, bortezomib and lenalidomide has created more possibilities for patients than many years before. In addition, autologous peripheral blood stem cell transplantation after high-dose melphalan has become the standard of care for younger patients. Allogeneic stem cell transplantation is an experimental option for those younger patients with a human leucocyte antigen identical donor. Because of these rapid developments and many treatment options we need good quality clinical studies that can guide us in what to do in everyday practice. This review will focus on those studies that have changed the treatment guidelines for patients with MM.

    A 67-year-old woman with refractory multiple myeloma was admitted to our hospital for salvage therapy. She developed fever several days after chemotherapy was initiated and complained of chest pain. Since abnormal electrocardiogram was demonstrated. Emergency coronary angiography was performed, but the coronary artery did not demonstrate stenosis. Thereafter, the patient was diagnosed as having takotsubo cardiomyopathy. Hydragogue and nitric acid preparation transiently improved chest symptoms, but high fever persisted despite antibiotic and antifungal agents. She died on the 9th day after the initiation of chemotherapy. Physicians need to be aware that cardiomyopathy may develop as a severe side effect of chemotherapy.

Renal impairment in patients with multiple myeloma: a consensus statement on behalf of the International Myeloma Working Group.
    Journal of clinical oncology : official journal of the American Society of Clinical Oncology, 2010, Nov-20, Volume: 28, Issue:33

    Renal impairment is a common complication of multiple myeloma (MM). The estimated glomerular filtration rate (eGFR) using the Modification of Diet in Renal Disease formula is the recommended method for the assessment of renal function in patients with MM with stabilized serum creatinine. In acute renal injury, the RIFLE (risk, injury, failure, loss and end-stage kidney disease) and Acute Renal Injury Network criteria seem to be appropriate to define the severity of renal impairment. Novel criteria based on eGFR measurements are recommended for the definition of the reversibility of renal impairment. Rapid intervention to reverse renal dysfunction is critical for the management of these patients, especially for those with light chain cast nephropathy. Bortezomib with high-dose dexamethasone is considered as the treatment of choice for such patients. There is limited experience with thalidomide in patients with myeloma with renal impairment. Thus, thalidomide can be carefully administered, mainly in the context of well-designed clinical trials, to evaluate if it can improve the rapidity and probability of response that is produced by the combination with bortezomib and high-dose dexamethasone. Lenalidomide is effective in this setting and can reverse renal insufficiency in a significant subset of patients, when it is given at reduced doses, according to renal function. The role of plasma exchange in patients with suspected light chain cast nephropathy and renal impairment is controversial. High-dose melphalan (140 mg/m(2)) and autologous stem-cell transplantation should be limited to younger patients with chemosensitive disease.

Multiple myeloma in the elderly: when to treat, when to go to transplant.
    Oncology (Williston Park, N.Y.), 2010, Volume: 24, Issue:11

    Until recently, standard treatment of multiple myeloma (MM) in elderly patients who were not candidates for autologous stem cell transplantation was with the combination of melphalan plus prednisone (MP). Novel agents (thalidomide, lenalidomide, bortezomib) are dramatically changing frontline therapy of MM. Randomized studies have shown the superiority of adding one novel agent to MP, either thalidomide (MPT) or bortezomib (MPV). The combination of lenalidomide with low doses of dexamethasone is another attractive alternative. Recent results show that maintenance therapy with low-dose lenalidomide may prolong progression-free survival. The objective of these improved treatment regimens should be to achieve complete response, as in younger patients. However, toxicity is a significant concern, and doses of thalidomide and of myelotoxic agents should be reduced in patients who are older than 75 years or who have poor performance status. Weekly bortezomib appears to induce severe peripheral neuropathy less frequently than the same agent administered twice weekly. Autologous stem cell transplantation is feasible in selected fit patients over 65 years of age, and its results are improved by the addition of novel agents before and after high-dose therapy. However, considering the progress in non-intensive therapy, autologous transplantation should not currently be offered to elderly patients outside of a clinical trial.

Treatment of multiple myeloma in the targeted therapy era.
    The Annals of pharmacotherapy, 2009, Volume: 43, Issue:2

    To review the clinical trials that have impacted treatment standards of multiple myeloma (MM).. A PubMed search (1980-June 2008) restricted to English-language publications was conducted using the key words multiple myeloma, clinical trials, targeted therapy, thalidomide, lenalidomide, bortezomib, dexamethasone, melphalan, autologous stem-cell transplantation, and tumor biology. Abstracts emanating from the meetings of the American Society of Clinical Oncology and American Society of Hematology from June 2002 to June 2008 were also reviewed.. Although hematopoietic stem-cell transplantation has improved the response rate and duration of overall survival, MM remains an incurable disease. However, focused research aimed at the molecular basis of the disease has led to a number of new treatment strategies. Evidence from clinical trials indicates that each of the 3 novel agents, thalidomide, lenalidomide, and bortezomib, is remarkably effective as first-line therapy. The data also suggest that clinicians may need to reevaluate the role of stem-cell transplantation in the disease.. Thalidomide, lenalidomide, or bortezomib in combination with dexamethasone have replaced traditional chemotherapy such as melphalan, doxorubicin, and vincristine as initial therapy of patients with MM who are eligible for stem-cell transplantation. Furthermore, these novel drugs can be incorporated into regimens used to treat transplant-ineligible patients or those with relapsing disease.

Multiple myeloma.
    Lancet (London, England), 2009, Jul-25, Volume: 374, Issue:9686

    Multiple myeloma is characterised by clonal proliferation of malignant plasma cells, and mounting evidence indicates that the bone marrow microenvironment of tumour cells has a pivotal role in myeloma pathogenesis. This knowledge has already expanded treatment options for patients with multiple myeloma. Prototypic drugs thalidomide, bortezomib, and lenalidomide have each been approved for the treatment of this disease by targeting both multiple myeloma cells and the bone marrow microenvironment. Although benefit was first shown in relapsed and refractory disease, improved overall response, duration of response, and progression-free and overall survival can be achieved when these drugs are part of first-line regimens. This treatment framework promises to improve outcome not only for patients with multiple myeloma, but also with other haematological malignancies and solid tumours.

First-line treatment of multiple myeloma in elderly patients: the GIMEMA (Gruppo Italiano Malattie EMatologiche dell'Adulto) multiple myeloma working party perspective.
    Current drug targets, 2009, Volume: 10, Issue:10

    Multiple myeloma (MM) is a neoplastic disorder affecting elderly people. The treatment for all patients with MM was, for about 40 years, based on the combination of melphalan plus prednisone, with a very low rate of complete remissions and a survival that remained unacceptably low (about 36 months). Diverse factors, including comorbidity, performance status, decreased physiologic reserve, and potential undertreatment, contribute to these poor outcomes. Recently, however, the reduced treatment-related morbidity and mortality associated with autologous stem-cell transplantation and the availability of effective new drugs with acceptable toxicity, such as thalidomide, lenalidomide and bortezomib, have greatly modified the traditional treatment paradigms in older patients with MM, challenging, in some cases, the definition of elderly and rapidly transforming the traditional palliative treatments to a new global therapeutic strategy, with the final objective of significantly improving the quality and the duration of life for elderly people with this disease. In this review, we report updated data for the front-line treatment of MM in the elderly population, examining the role of new drugs combined with melphalan or their incorporation within more complex combinations, including other so-called conventional drugs such as (pegylated)-doxorubicin, cyclophosphamide, and dexamethasone. We also assess the role of autologous and allogeneic stem-cell transplantation with adjusted conditioning regimens in selected elderly patients.

[Complete remission of nephrotic syndrome and improvement of renal function in a patient with light chain deposition disease following high dose chemotherapy with transplantation of autologous haematopoietic stem cells. A case study and review of literatu
    Vnitrni lekarstvi, 2009, Volume: 55, Issue:11

    Light chain deposition disease (LCDD) damages most frequently kidneys, and less frequently other organs. The incidence of LCDD is lower than the incidence of AL-amyloidosis. Symmetric swelling of both legs was the first sign of nephrotic syndrome with renal insufficiency in our female patient. Renal biopsy specimen revealed the diagnosis of LCDD. Bone marrow biopsy contained 40% of plasma cells. Bone survey showed no osteolytic changes. These findings confirmed the diagnosis of multiple myeloma (MM) Durie Salmon stage IB with LCDD. The patient was initially treated with 4 cycles of VAD (vinkristine, adriamycine, dexamethasone) chemotherapy with no response. Followed collection of peripheral haematopoietic stem cells and later high dose chemotherapy with reduced dose of melphalan 140 mg/sqm and autologous peripheral haematopoietic stem cells transplantation. Melphalan dose was reduced because of renal insufficiency (serum creatinine 290 micromol/l) before application of conditioning regimen. High dose therapy was complicated by with deterioration of renal function, creatinine increased to 600 micromol/l. Worsening of renal function was most likely caused by nephrotoxicity of melphalan in nephrotic syndrome. This has been previously described in patients with AL-amyloidosis, and nephrotic syndrome who were treated with high dose melphalan. This phenomenon was entitled "post conditioning renal insufficiency". Hypoalbuminemia hypoproteinemia and reduced intravascular volume and renal damage caused by amyloid deposits as well as probably, amorphous non-amyloid deposits of monoclonal immunoglobulin are likely to have contributed to nephrotoxicity of the high dose of melphalan. However, worsening of renal insufficiency was facilitated by the mucositis-associated sepsis. Follow-up examination one month after high dose chemotherapy showed complete remission, that was confirmed by further examinations. In the course of the first year after high dose chemotherapy renal function gradually improved and nephrotic syndrome completely disappeared (complete kidney remission). Proteinuria declined to 2-3 g/24 hours and glomerular filtration slowly improved. Three years after high dose chemotherapy the patient is still in complete remission of multiple myeloma and free of nephrotic syndrome, with slightly increased creatinine (160 micromol/l) that, nevertheless, has had an improving tendency over last 3 years. The present case study illustrates accomplishment of complete ha

Auer rod-like intracytoplasmic inclusions in multiple myeloma. A case report and review of the literature.
    International journal of laboratory hematology, 2009, Volume: 31, Issue:2

    Several intracytoplasmic morphological changes in the plasma cells of multiple myeloma have been described previously. However, Auer rod-like inclusions are rarely found in these types of cells. Here, we report a case of multiple myeloma with Auer rod-like, needle-shaped intracytoplasmic inclusions in plasma cells. A review of all published cases revealed that this phenomenon is exclusively found in myeloma with kappa-type paraprotein. The nature of these intracellular inclusions and the relationship to prognostic implications and concomitant illnesses are discussed.

Frontline treatment of multiple myeloma in elderly patients.
    Blood reviews, 2008, Volume: 22, Issue:6

    Until 2007, frontline chemotherapy with melphalan and prednisone (MP) was considered as the standard of care in the treatment of elderly patients with multiple myeloma (MM). Recently, several prospective randomized studies comparing MP with the same combination plus new agents such as thalidomide (MPT) or bortezomib (MPV) clearly showed that MPT and MPV were superior to MP in terms of progression-free and overall survival. Melphalan-prednisone-lenalidomide (MPR) is currently compared to MP in one prospective trial and will also probably be superior to MP. Lenalidomide plus low-dose dexamethasone is a promising combination. Thus, at least four highly active new treatment options are now available to treat elderly patients with MM. The goal of future trials will be to determine the best treatment strategy in this group of patients.

Advances in therapy of multiple myeloma.
    Current opinion in oncology, 2008, Volume: 20, Issue:6

    To summarize the results of treatment of multiple myeloma in the era of novel agents.. Recent publications comparing autologous stem cell transplantation (ASCT) with conventional chemotherapy in the era of 'old' drugs have shown that the contribution of ASCT in the treatment of multiple myeloma has been modest. Five trials comparing single vs. double ASCT showed an increased progression-free survival in three of them, whereas the overall survival was significantly prolonged in one. The benefit would be only for patients failing to achieve very good partial response with the first transplant. The results of allogeneic transplantation with reduced-intensity conditioning, particularly after debulking with an ASCT, are encouraging. On the contrary, the impact of pretransplant induction regimens with novel agents (thalidomide, bortezomib and lenalidomide) on the posttransplant outcome is being investigated in several large phase III trials. For elderly patients, the combination of 'old' therapies with thalidomide, bortezomib or lenalidomide has resulted in the melphalan-prednisone-thalidomide, melphalan-prednisone-Velcade, melphalan-prednisone-Revlimid and lenalidomide/dexamethasone regimens, which are highly effective.. ASCT has resulted in a modest contribution in the treatment of multiple myeloma. Hopefully, its impact will be increased with the incorporation of novel agents in the pretransplant induction regimens. The combination of thalidomide, bortezomib or lenalidomide with melphalan-prednisone or with dexamethasone has resulted in highly effective regimens for patients not eligible for high-dose therapy/stem cell transplantation.

Role of thalidomide in previously untreated patients with multiple myeloma.
    Expert review of anticancer therapy, 2008, Volume: 8, Issue:10

    Thalidomide represents one of the most relevant therapeutic advances for patients with multiple myeloma over the last 10 years. Despite some toxicities, it has demonstrated significant efficacy in elderly patients, as well as in the setting of younger subjects receiving autologous stem cell transplantation. Here, we report and discuss the clinical results achieved with thalidomide alone or in combination with dexamethasone or other drugs, such as melphalan, cyclophosphamide, doxorubicin and bortezomib, in previously untreated myeloma patients.

High-dose therapy in patients with plasma cell dyscrasias and renal dysfunction.
    Contributions to nephrology, 2007, Volume: 153

    Multiple mycloma causes a disproportionate amount of the malignancy-related renal insufficiency. Acute renal insufficiency in myeloma patients can occur due to dehydration, hypercalcemia, side effects of medications (NSAIDs) or tumor lysis syndrome in addition to cast nephropathy, amyloidosis and light chain deposition disease. Patients on hemodialysis have traditionally been excluded from antineoplastic therapy due to fear of side effects and lack of studies addressing benefit. Melphalan is the most effective chemotherapeutic agent in myeloma and its PK (pharmacokinetics) are not adversely affected by impaired renal function. Because of more pronounced toxicity of Melphalan 200 mg/m2 conditioning regimen, Melphalan 140 mg/m2 has become the standard of care. 24% of patients become dialysis-independent at a median of 4 months after autotransplantation. Favorable factors for becoming dialysis independent were duration of dialysis 10 ml/min. While no good data are available on the use of thalidomide in the presence of renal failure, it is our experience that severe neuropathy, constipation, lethargy and bradycardia are more frequent in patients with creatinine >or=3 mg/dl. It has become apparent that bisphosphanates-zoledronic acid more than pamidronate-cause renal dysfunction. If patients remain dialysis-dependent after autotransplantation, we recommend to delay considering a renal transplant until at least 3 years after the first transplant.

    After decades of minimal progress, two new classes of drugs with novels mechanisms of action: immunomodulatory drugs (thalidomide and lenalidomide) and proteasome inhibitors (bortezomib) have shown great activity for the treatment of multiple myeloma.. Thalidomide acts by a variety of mechanisms; its efficacy is well known in disease relapse especially associated with dexamethasone. Recent results prove that combination of thalidomide with melphalan and prednisone should be considered as the first line standard of care in elderly patient. The main side effects are peripheral neuropathy and deep-vein thrombosis. Bortezomib is the first proteasome inhibitor. It is approved for the treatment in first disease relapse. The combination with glucocorticoids is synergistic. This combination in induction treatment before autologous stem cell transplantation is promising, as well as the combination with melphalan and prednisone in elderly patient. The main toxicities are fatigue and peripheral neuropathy. Lenalidomide is a structural analogue of thalidomide. Its efficacy in combination with dexamethasone has been proved in relapsing patients. The main toxicity is hematologic. Utilisation as first line treatment is also promising.. These three drugs have toxicities predictable and manageable and can be used successively or in combination for greater effectiveness. They have an impact on the multiple myeloma treatment strategies and on the disease course itself.

Individualizing therapy using molecular markers in multiple myeloma.
    Clinical lymphoma & myeloma, 2007, Volume: 7 Suppl 4

    Multiple myeloma is a heterogeneous disease with complex genetics, including a variety of primary and secondary genetic events that contribute to disease pathogenesis. Good risk genetics include hyperdiploidy (approximately 40%) and cyclin D translocations (t[11;14] and t[6;14]; approximately 18%). Poor risk genetics include t(4;14), approximately 15%; MAF translocations (t[14;16]) and t[14;20]; approximately 8%); secondary genetic events such as deletion p53, and abnormal cytogenetics (deletion 13 or hypodiploidy). Proliferation is the other poor risk feature, as measured by either plasma cell labeling index, beta(2)-microglobulin, or gene expression profiling; it is identified in all genetic subtypes and not yet captured by any genetic marker. Altogether, approximately 75% of patients are good risk and if eligible, do well with high-dose melphalan and autologous stem cell transplantation. In contrast, about 25% of the patients have poor risk features and receive only transient benefit from this approach. We propose the Mayo Stratified Myeloma and Risk-Adapted Therapy. Stem cell transplantation is deferred in patients with high-risk molecular markers, and in all patients, response is followed closely and determines the individual timing and sequence of therapeutic regimens.

Melphalan and its role in the management of patients with multiple myeloma.
    Expert review of anticancer therapy, 2007, Volume: 7, Issue:7

    Melphalan is an alkylating agent approved for the treatment of multiple myeloma and ovarian cancer. The combination of oral melphalan and prednisone was first introduced in the 1960s and remains the standard therapy for elderly multiple myeloma patients. High-dose melphalan followed by autologous stem cell support became the standard treatment for younger patients since the 1990s. The occurrence of drug resistance is the major limiting factor for the long-term success of this therapy, and relapse always occurs. In recent years, advances in the understanding of the pathogenesis of myeloma and the mechanism of drug resistance have led to the development of novel targeted therapies that are able to overcome resistance and show additive or synergistic effects with melphalan. Thalidomide, its immunomodulatory derivative lenalidomide and the proteasome inhibitor bortezomib, in combination with oral melphalan in the elderly and with intravenous melphalan in younger patients, are changing the traditional treatment paradigm of multiple myeloma.

Melphalan: old and new uses of a still master drug for multiple myeloma.
    Expert opinion on investigational drugs, 2007, Volume: 16, Issue:9

    The treatment of multiple myeloma has seen significant changes from the initial use of melphalan to the introduction of stem cell transplantation and, most recently, to the era of novel targeted agents. Melphalan still remains as a reference drug for combination regimens, including emerging newer therapeutic options, either used at a standard dose for initial or salvage treatments in patients who are not eligible for more intensive therapies, or in conjunction with new molecules within high-dose chemotherapy programs. In this review, the authors analyze old and novel regimens, including melphalan for the treatment of newly diagnosed or relapsed/resistant patients with multiple myeloma in the clinical settings of standard chemotherapy, as well as autologous or allogeneic stem cell transplantation.

    Many changes have been incorporated into the approach to multiple myeloma over the last few years, due to improvements in our understanding of the disease biology. New diagnostic and prognostic criteria from the International Myeloma Working Group have clarified the initial clinical approach to this disease. The prognostic impact of chromosomal abnormalities is now recognized, and the detection of specific abnormal cytogenetics is beginning to influence therapeutic decisions. The introduction of the novel agents thalidomide, bortezomib and lenalidomide has expanded treatment options at different points in the disease course; these agents are being evaluated in conjunction with conventional chemotherapy and stem cell transplantation. This report highlights some of the key recent findings in multiple myeloma, and describes areas for future research.

    The multiple myeloma (MM) has an incidence of 3-4/100,000 in the Caucasian population. MM has to be distinguished from smouldering MM and monoclonal gammopathy of uncertain significance (MGUS). In younger patients (<65 years) a good long-term remission is the aim of therapy, while in the elderly patients with comorbidities the aim is a good partial remission with good quality of life. In the elderly this can be achieved with a combination of melphalan and prednisone. High-dose chemotherapy, often as a tandem transplantation, is part of standard therapy of MM patients <65 years. However, allogeneic stem cell transplantation is the only curative approach. New substances approved for treatment of relapsed MM include bortezomib, thalidomide, and lenalidomide.

High-dose treatment with autologous stem cell transplantation in multiple myeloma: past, present, and future.
    Seminars in hematology, 2007, Volume: 44, Issue:4

    High-dose chemotherapy (HDT) with autologous stem cell transplantation (ASCT) has been used in the treatment of multiple myeloma since the early 1980s. Its present position as the backbone of first-line treatment in patients up to 60 to 65 years of age is the result of several controlled randomized trials, where its superiority over standard chemotherapy has been demonstrated. However, the method is not considered to have curative potential, with the possible exception of a small proportion of about 5% to 10% of patients with very long-standing complete remissions (CRs) of more than 8 years. Over the years, there have been several attempts to improve the technique, where, for example, tandem transplants and post-transplant maintenance treatment have been successful, at least in certain subgroups of patients, while others, such as graft purging, have been of no value. Treatment results need further improvement, particularly in poor-prognosis disease--based on abnormal karyotype and high beta2-microglobulin--and the future will show if the introduction of novel drugs like bortezomib, thalidomide, and lenalidomide will lead to longer survival and prolongation of disease control in multiple myeloma.

Clinical updates and nursing considerations for patients with multiple myeloma.
    Clinical journal of oncology nursing, 2007, Volume: 11, Issue:6

    Multiple myeloma accounts for approximately 1% of all new cancers and is characterized by abnormal plasma cell proliferation in the bone marrow. As a result, many patients develop bone lesions, hypercalcemia, anemia, and renal impairment. Although no cure exists for multiple myeloma, current treatments, such as oral melphalan and prednisone, can slow disease progression and prolong overall survival. Several new therapeutic options show promise: lenalidomide, thalidomide, liposomal doxorubicin, and bortezomib. Clinical research presented at the 2006 meeting of the American Society of Hematology, the 2007 meeting of the American Society of Clinical Oncology, and the 11th International Myeloma Workshop showed that newer therapeutic combinations were well tolerated and effective in patients with multiple myeloma. Oncology nurses, with their specialized knowledge of treatment administration and monitoring and their expertise in patient education, have an important role in the management of patients with multiple myeloma to help improve overall survival and quality of life. As newer regimens become available, oncology nurses must be aware of factors that optimize outcomes to help patients understand the benefits of treatment, how to manage side effects, and the importance of treatment adherence.

    Renal involvement is common in multiple myeloma. Although several types of renal disease are observed, most of them are considered to be specifically related to monoclonal immunoglobulin light chains. Myeloma cast nephropathy is the most frequent and sometimes associated with acute renal failure. AL amyloidosis and monoclonal immunoglobulin deposit disease are often presented as a nephrotic syndrome. In this review, we describe the pathogenesis and diagnosis of these three renal diseases. We also focus on the treatment of renal disease in multiple myeloma, in the view points of the chemotherapy to reduce M-protein and the prevention to reduce the risks of promoting renal injury.

    The combination of the melphalan and prednisolone (MP) can induce objective responses in about 50% of patients with multiple myeloma (MM) since its introduction in 1960. Since then many combination chemotherapy regimens have been used, but a large metaanalysis showed that the combination of oral MP is as effective as combination regimens including intravenous drugs. In recent years, many novel agents (including bortezomib, thalidomide, and liposomal doxorubicin) have been developed for the MM treatment. More recently, MP has been used in combination with these novel agents. The combination treatment of MP and thalidomide, overall survival was significantly better than seen in the MP treatment. In the near future, primary induction therapy will be changed.

    The proteasome inhibitor bortezomib is approved for the treatment of patients with relapsed/refractory multiple myeloma. Botezomib represents a new generation of treatments for multiple myeloma that affects both specific intracellular signaling pathways and the tumor microenvironment. There is a growing body of clinical evidence showing its effectiveness alone and in combination not only in relapsed/refractory cases but also in the front line setting. Regimens incorporating bortezomib and other novel agents such as immunomodulatory derivatives of thalidomide together with commonly used conventional drugs show considerable high response rates including complete response that resulting in improving survival, with or without following stem cell transplantation. Thus these approaches represent a promising future direction in myeloma treatment.

Frontline treatment in multiple myeloma patients not eligible for stem-cell transplantation.

    Melphalan-prednisone-thalidomide (MPT) currently appears to be the treatment of choice for a large proportion of elderly patients ineligible for autologous stem-cell transplantation (ASCT). It seems certain that in the near future melphalan-prednisone-Velcade (MPV) and melphalan-prednisone-lenalidomide (MPR) will also be proved superior to melphalan-prednisone (MP), thus providing three therapeutic options (MPT, MPV and MPR) in this patient group with multiple myeloma (MM). These therapeutic options could lead to more personalized treatment approaches, based on patient comorbidities, as the three novel therapies have somewhat different toxicity profiles. MP would be appropriate for only a minority of patients with poor performance status and/or significant comorbidities, such as severe neuropathy or a contraindication to anticoagulants. Questions regarding the relative efficacy of melphalan-based regimens versus dexamethasone-based regimens (preferably with low-dose dexamethasone) will require randomized phase-III trials. More intensive approaches with new drug combinations or with the incorporation of polyethylene glycolated (PEGylated) liposomal doxorubicin will also require additional studies. Additionally, the important issue of maintenance treatment needs to be further investigated, especially in elderly patients.

    La Revue du praticien, 2006, Jan-15, Volume: 56, Issue:1

    Multiple myeloma is a blood disease that is often easy to diagnose, relying on a combination of an excessive medullary plasmacytosis, a serum and/or urinary monoclonal immunoglobulin and one or several signs of organ involvement (anemia, renal failure, bone lesions, hypercalcaemia, infections). The beta2m, serum albumin, and certain chromosomal anomalies of the malignant clone are the essential prognostic factors. Intensive treatment with auto-transplantation of stem cells of peripheral blood is a significant development from which patients less than or equal to 65 years of age have benefited. The diphosphonates are combined with chemotherapy in order to limit the effect on bones, and recombinant erythropoietin is used in certain patients. Above all, therapeutic progress has been made thanks to thalidomide, bortezomib and lenalidomide, even if the optimal utilisation of these molecules is still to be determined.

Treatment of multiple myeloma: an emphasis on new developments.
    Annals of medicine, 2006, Volume: 38, Issue:2

    Not all patients who fulfill the minimal criteria for diagnosis of multiple myeloma should be treated. If doubt exists about beginning therapy, one should wait and re-evaluate the patient in 2 or 3 months. There is no evidence that early treatment of multiple myeloma is advantageous. All patients should be considered possible candidates for an autologous stem cell transplantation. If they are deemed to be eligible, they should be treated for 3 to 4 months with therapy that does not damage the hematopoietic stem cells. Currently, most physicians use thalidomide plus dexamethasone or dexamethasone alone for induction. Vincristine, doxorubicin (Adriamycin), and dexamethasone (VAD) have been used in the past. Autologous stem cell transplantation prolongs disease-free survival and overall survival. The treatment-related mortality rate is 1% to 2%. Melphalan, 200 mg/m2, is the most widely used preparative regimen. Although allogeneic transplantation is attractive, the mortality rate (about 20%) is too high to recommend conventional allogeneic transplantation. Non-myeloablative transplantation is currently under investigation. If the patient is not a candidate for autologous stem cell transplantation, therapy with melphalan and prednisone is a good choice. Patients with relapsed or refractory disease may be treated with dexamethasone, thalidomide and dexamethasone, bortezomib (Velcade, PS-341), or lenalidomide (Revlimid, not yet approved by the Food and Drug Administration).

Management of multiple myeloma with bortezomib: experts review the data and debate the issues.
    Oncology, 2006, Volume: 70, Issue:6

    Cure for multiple myeloma is rare; the success of treatment is measured by response, and length of remissions and survival. Initial treatment for patients young and fit enough is high-dose chemotherapy with autologous stem cell transplantation. Various chemotherapy regimens are employed as initial therapy in patients who cannot withstand the autologous stem cell transplantation regimen, and for treatment of refractory or relapsed disease. Commonly used agents either alone or in combination have included dexamethasone, vincristine, doxorubicin, melphalan, cyclophosphamide, etoposide, cisplatin and, more recently, thalidomide. Within the past few years, the first-in-class proteasome inhibitor bortezomib has been introduced for the treatment of relapsed multiple myeloma with data demonstrating efficacy and safety. Throughout Europe, a faculty of experts conducted a series of debates with over 450 clinicians to discuss the efficacy of bortezomib vis-à-vis other available therapies. Of primary concern was the place of bortezomib in maximizing efficacy throughout the course of the disease and treatment by increasing response rates and improving duration of response, while maintaining an acceptable level of toxicity. The experts concluded that bortezomib, with its unique mechanism of action and demonstrated clinical efficacy and safety, should be considered as standard, early treatment in patients with relapsed multiple myeloma, especially after first relapse.

Treatment of myeloma in patients not eligible for transplantation.
    Current treatment options in oncology, 2005, Volume: 6, Issue:3

    Multiple myeloma (MM) remains an incurable disease for most patients, with a median survival of 4 to 5 years. High-dose chemotherapy followed by transplantation has resulted in improvement in response rates and survival compared with conventional therapy, but relapse is nearly universal and not all patients are candidates for this option of aggressive treatment. Standard therapeutic strategies for newly diagnosed patients not eligible for transplantation include pulsed high-dose dexamethasone, melphalan with prednisone, and vincristine in combination with doxorubicin and dexamethasone, as well as other combinations of alkylating agents. Emerging therapies under clinical investigation for first-line therapy include thalidomide, the thalidomide analog lenalidomide, and the proteasome inhibitor bortezomib alone and in combination with other agents, particularly dexamethasone. At an interim analysis, thalidomide combined with melphalan and prednisone was shown to induce a complete or near complete remission (CR) rate of 28% and overall (complete+partial) response rate of 77% in elderly patients generally not eligible for transplantation. These results are comparable to those obtained with high-dose therapy and may obviate transplantation in these patients. Induction therapy with bortezomib-based combinations induces complete and near complete remissions in a similar proportion of patients. These regimens include bortezomib and dexamethasone alone and in combination with doxorubicin, thalidomide, or melphalan. Use of thalidomide or bortezomib does not preclude stem cell harvest. Survival benefits need to be firmly established before these novel regimens emerge as the new standard of care for newly diagnosed disease. However, front-line treatment with combinations involving these agents is a promising strategy that may improve the standard of care for patients both eligible and ineligible for stem cell transplantation.

Current treatment options for myeloma.
    Expert opinion on pharmacotherapy, 2005, Volume: 6, Issue:7

    In most cases multiple myeloma is an incurable plasma cell malignancy. Despite the use of conventional therapy or high-dose chemotherapy with autologous stem cell transplantation (ASCT), patients continue to relapse at a constant rate. A small minority of patients are cured by allogeneic transplantation. Novel drugs targeting not only the myeloma cell but also its interactions with the malignant microenvironment have recently been used in patients with relapsed/refractory disease. So far, ASCT has been the treatment of choice for eligible myeloma patients. However, many questions regarding the management of myeloma patients remain unanswered. How safe is ASCT in elderly patients? Is there a role for non-myeloablative allogeneic transplantation in multiple myeloma? What is the role of novel agents, such as thalidomide, its analogues and bortezomib, in the treatment of newly diagnosed patients or as maintenance post-ASCT? This review summarises all available data for the current treatment options for myeloma providing a useful algorithm for its management.

Focal and segmental glomerulosclerosis and plasma cell proliferative disorders.
    American journal of kidney diseases : the official journal of the National Kidney Foundation, 2005, Volume: 46, Issue:2

    Focal and segmental glomerulosclerosis (FSGS) is a common histological finding in patients with proteinuria. The natural history of the condition varies, and although it may be responsive to therapy, FSGS is an important cause of end-stage renal disease. FSGS can be caused by a variety of conditions, but it has been reported rarely in association with a plasma cell disorder.. Mayo Clinic databases were queried and cross-referenced for FSGS and plasma cell disorders. The diagnoses were confirmed, and relevant clinical and laboratory data were abstracted.. A cohort of 13 patients with "idiopathic" FSGS and a monoclonal plasma cell disorder were identified. Four patients had myeloma, and 9 patients had monoclonal gammopathy of undetermined significance. Patients treated for myeloma experienced improvement in their renal lesion, and the latter relapsed when the myeloma relapsed.. We show that FSGS and plasma cell disorders are temporally and epidemiologically linked. Therapy for the underlying plasma cell disorder can lead to resolution of FSGS. The emerging molecular pathogenesis of both FSGS and myeloma also provides potential mechanisms that link the 2 conditions together. Thus, physicians must rule out a plasma cell proliferative disorder in patients with FSGS before concluding that the renal lesion is idiopathic. Moreover, FSGS may respond favorably after the underlying plasma cell disorder is controlled.

Multiple myeloma: diagnosis and treatment.
    Mayo Clinic proceedings, 2005, Volume: 80, Issue:10

    Major advances have occurred in our understanding of the biology of multiple myeloma (MM) and in its treatment in the past decade. New diagnostic criteria have been developed, and an international Staging System has replaced the Durle-Salmon Staging System. It is now possible to classify MM as standard risk or high risk on the basis of specific Independent prognostic factors. The role of single and double autologous stem cell transplantation has been clarified by randomized trials. Most importantly, thalidomide, bortezomib, and lenalidomide have emerged as new active agents and are being incorporated rapidly into the treatment of both newly diagnosed and relapsed MM. The current approach to the diagnosis, prognosis, and management of MM is reviewed.

New treatments for multiple myeloma.
    Oncology (Williston Park, N.Y.), 2005, Volume: 19, Issue:14

    In 2004, multiple myeloma was diagnosed in more than 15,000 people in the United States and will account for approximately 20% of deaths due to hematologic malignancies. Although traditional therapies such as melphalan (Alkeran)/prednisone, combination chemotherapy with VAD (vincristine, doxorubicin [Adriamycin], and dexamethasone), and high-dose chemotherapy with stem cell transplantation have shown some success, median survival remains between 3 to 5 years. Treatment options for patients with multiple myeloma have increased in recent years, with the promise of improvement in survival. New agents, such as the proteasome inhibitor bortezomib (Velcade), the antiangiogenic and immunomodulator thalidomide (Thalomid) and its analogs, such as lenalidomide (Revlimid), together with other small molecules, including arsenic trioxide (Trisenox), and other targeted therapies, have been studied alone and in combination with other antineoplastic therapies, either as induction therapy prior to stem cell transplantation or in patients with relapsed disease. Bortezomib recently was approved in the United States for the treatment of multiple myeloma in patients who have received at least one prior therapy. The use of bortezomib-based regimens as front-line therapy as well as the use of other agents in multiple myeloma remain under investigation, and approvals for both thalidomide and lenalidomide are hoped for soon, with the overall prospect of patient outcome continuing to be increasingly positive.

Treatment of multiple myeloma.
    Blood, 2004, Jan-01, Volume: 103, Issue:1

    Autologous peripheral blood stem cell (PBSC)-supported high-dose melphalan is now considered standard therapy for myeloma, at least for younger patients. The markedly reduced toxicity of allotransplants using nonmyeloablative regimens (mini-allotransplantations) may hold promise for more widely exploiting the well-documented graft-versus-myeloma (GVM) effect. New active drugs include immunomodulatory agents, such as thalidomide and CC-5013 (Revimid; Celgene, Warren, NJ), and the proteasome inhibitor, PS 341 (Velcade; Millenium, Cambridge, MA), all of which not only target myeloma cells directly but also exert an indirect effect by suppressing growth and survival signals elaborated by the bone marrow microenvironment's interaction with myeloma cells. Among the prognostic factors evaluated, cytogenetic abnormalities (CAs), which are present in one third of patients with newly diagnosed disease, identify a particularly poor prognosis subgroup with a median survival not exceeding 2 to 3 years. By contrast, in the absence of CAs, 4-year survival rates of 80% to 90% can be obtained with tandem autotransplantations. Fundamental and clinical research should, therefore, focus on the molecular and biologic mechanisms of treatment failure in the high-risk subgroup.

Multiple myeloma.
    Lancet (London, England), 2004, Mar-13, Volume: 363, Issue:9412

    Multiple myeloma is a malignant disease of plasma cells that manifests as one or more of lytic bone lesions, monoclonal protein in the blood or urine, and disease in the bone marrow. Treatment for myeloma has changed beyond recognition in the past decade, and now includes state of the art supportive treatment and infusional chemotherapy courses, followed for younger patients by high-dose melphalan and an autologous transplant. Patients younger than 70 years can now expect a doubling of median survival to 5 years, a 20% chance of surviving longer than 10 years, and a 50% chance of attaining complete morphological and biochemical remission. Bisphosphonate control of bone disease is essential. Exploitation of the understanding of the biology of myeloma has led to the development of biological treatments, such as thalidomide, CC-5013, and bortezomib, which target the myeloma cell and the bone-marrow microenvironment, which plays a crucial part in the disease's pathogenesis. These treatments will hold the key to future success.

[Granulocyte-colony stimulating factor-producing myeloma with clinical manifestations mimicking chronic neutrophilic leukemia].
    [Rinsho ketsueki] The Japanese journal of clinical hematology, 2004, Volume: 45, Issue:3

    A 68-year-old man was diagnosed as having bronchial asthma in November 1996. He presented with leukocytosis in June 2002. The WBC count was 29,900/microliter with 82% mature neutrophils showing toxic granules. The neutrophil alkaline phosphatase score and serum level of vitamin B12 were elevated. Bone marrow demonstrated myeloid hyperplasia and plasmacytosis. Cytogenetic and molecular analyses were negative for Philadelphia chromosome and BCR/ABL fusion gene. Lambda-type Bence-Jones protein was detected on the serum and urinary immunoelectrophoresis. The coexistence of chronic neutrophilic leukemia and myeloma was suspected based on the clinical features. The serum level of granulocyte-colony stimulating factor (G-CSF) was elevated. Immunohistochemically, atypical plasma cells were positive for anti G-CSF antibody. Finally, we diagnosed this patient as having a G-CSF-producing myeloma. Treatment with melphalan and prednisolone was initiated without beneficial response. He was then admitted to our hospital for ROAD therapy (ranimustine, vincristine, melphalan, and dexamethasone). The neutrophil count decreased in parallel with the serum G-CSF level. These observations indicated that the neutrophilia in this case was probably caused by a reactive response to G-CSF secreted from the myeloma cells.

Changing concepts in multiple myeloma: from conventional chemotherapy to high-dose treatment.
    European journal of cancer (Oxford, England : 1990), 2003, Volume: 39, Issue:1

    The treatment of Multiple Myeloma (MM), a malignant plasma cell disorder has changed considerably over the past decade. It has been convincingly shown that intensive treatment supported by autologous stem cell reinfusion is superior to conventional chemotherapy with alkylating agents or vincristine, doxorubicin and dexamethasone (VAD) alone in terms of a more rapid response and a longer disease-free survival. However, cure is not achieved in the majority of patients. Several trials have therefore focussed on repeated intensive treatments in order to improve the survival of these patients. Other approaches are aimed at identifying patients on the basis of prognostic factors, who may benefit from high-dose therapy. This review discusses the recent developments in intensive therapy for multiple myeloma.

Pharmacotherapy of multiple myeloma: an economic perspective.
    Expert opinion on pharmacotherapy, 2003, Volume: 4, Issue:4

    Since new treatments have recently been proposed for patients with multiple myeloma, the aim of this article is to review the main innovations in this therapeutic area and to examine the cost-effectiveness ratio. Innovative approaches include autologous transplantation and thalidomide, which are both utilised as induction or salvage treatments. According to a randomised trial conducted in 1996, the survival after autologous transplantation seems to be better than that following standard therapy; however, this result has not been confirmed by a recent study. Thalidomide has been found to be effective for relapsed or refractory myeloma and, more recently, also as induction therapy. Preliminary cost-effectiveness assessments about autologous transplantation and thalidomide have given promising results; yet one regulatory problem with thalidomide is that, both in Europe and in the US, the drug has not yet been approved for this indication.

Management of multiple myeloma: a systematic review and critical appraisal of published studies.
    The Lancet. Oncology, 2003, Volume: 4, Issue:5

    We have done a systematic review of all randomised studies in myeloma, identified through a comprehensive search. Our aim was to investigate and critically examine the effects of various treatment modalities on outcome in patients with multiple myeloma and address 22 specific clinical questions in the management of this disease. As a result of our analysis we identified two therapeutic advances in the management of myeloma that, according to the evidence, are most important for improving outcome. These advances were: introduction of high dose chemotherapy, which appears to be superior to conventional chemotherapy, and the use of bisphosphonates, which decrease the probability of pathological vertebral fractures. However, the overall quality of the body of evidence for myeloma management was poor. Many trials were done with small sample sizes, and did not include reporting power analysis. The majority of studies had inadequate allocation concealment, and few were analysed according to intention to treat principle. We conclude that the quality of total evidence supporting treatment recommendations in myeloma is modest at best and has an ample scope for improvement.

Breakthroughs in the management of multiple myeloma.
    Drugs, 2003, Volume: 63, Issue:16

    Although multiple myeloma remains a terminal illness, the past four decades have seen a dramatic change in the outlook for a newly diagnosed patient in terms of therapies available, supportive care and insight into the pathogenesis of this disease. Among the newer agents available for treatment, thalidomide has been resurrected and discovered to be a valuable therapy for myeloma. Thalidomide appears to work, at least in part, through its anti-angiogenic properties, but much remains to be learned about its mechanism of action as well as optimal administration regimens. With the development of increasingly more potent bisphosphonates it has become possible to diminish the painful skeletal complications of myeloma, one of the most devastating problems of this disease. The most recent generation of bisphosphonates, pamidronic acid and zoledronic acid, have provided a statistically significant decrease in the skeletal complications of myeloma when used in a prophylactic manner. These agents appear to work by inhibiting osteoclast function. Progressive improvement in cytogenetic techniques has now demonstrated that almost all patients with myeloma have chromosomal abnormalities, some of which appear to confer varying degrees of prognostic significance. In particular, the changes in chromosome 13 are associated with an unusually poor outcome. These findings are serving as a guide toward learning more about the pathogenesis of myeloma as well as in identifying potential targets for therapy. Stem cell transplantation has emerged as the standard treatment for the large majority of patients with myeloma following the demonstration of superior complete remission and survival, both disease-free and overall, in a French randomised trial. Unfortunately, virtually all patients will eventually relapse following autologous stem cell transplantation, prompting continuing efforts such as tandem transplants, CD34+ selection, as well as modifications in the conditioning regimen to improve outcomes. Allogeneic bone marrow transplants appear to offer a better chance for a possible cure of myeloma but have been associated with an unusually high mortality. However, this approach is being revived with the advent of the less toxic non-myeloablative transplant that has provided an 81% short-term survival in a trial combining this approach with an initial conventional autologous bone marrow transplant. Immunotherapy with dendritic cells appears now to be a feasible way to enhance inna

High intensity regimens with autologous hematopoietic stem cell transplantation as treatment of multiple myeloma.
    Annals of transplantation, 2002, Volume: 7, Issue:2

    The treatment of multiple myeloma still remains under investigation. Conventional chemotherapy with currently used agents (i.e., Melphalan) effects complete remission in no more than 5% of patients. High dose chemotherapy followed by hematopoietic stem cells transplantation results in complete remission rates between 25% and 75% and a 3-year probability of event-free survival between 40% and 60% but is not curative since most patients relapse after 1.5 to 3 years. Therefore, it becomes the treatment of choice for multiple myeloma. The drugs used in high dose therapy include: high dose melphalan (200 mg/m2) as single agent., melphalan (140 mg/m2) and total body irradiation (TBI), Busulfan and melphalan... etc. The use of the peripheral blood stem cell transplantation has allowed a reduction in the toxicity of high-dose regimens, but has not led to an increase in the overall response rate or survival. Hematopoietic stem cells from peripheral blood are preferred for transplantation because they restore hematopoiesis more rapidly than do bone marrow cells and the numbers of tumor cells are lower in peripheral blood than bone marrow cells. Peripheral blood stem cell transplantation was associated with significant reduction in the duration of aplasia and transfusion requirements. Several regimens have been proposed for stem cells mobilization including: High-dose cyclophosphamide and G or GM-CSF, G-CSF alone, and cyclophosphamide and etoposide with G-CSF... ect.. Further attempts to improve the results of autotransplantation have included intensification with tandem transplantations (double transplants) and reduction of tumor cells in stem cell infusion. The aim of this review is to summarize the current knowledge about the treatment of multiple myeloma with high dose chemotherapy with autologous hematopoietic stem cell transplantation.

High-dose therapy and immunomodulatory drugs in multiple myeloma.
    Seminars in oncology, 2002, Volume: 29, Issue:6 Suppl 17

    The principle of alkylating agent dose intensity, especially with melphalan-based tandem autotransplants, has been effective in increasing the rate of complete remission beyond 40% and effecting 10-year survivorship in about 40% of the three fourths of patients presenting without cytogenetic abnormalities (Total Therapy I). Further dose escalation and post-transplant consolidation therapy, as practiced with Total Therapy II, seems to further improve results in these patients, but not in those with chromosome 13 abnormalities or lactate dehydrogenase elevation. Phase III trials for post-transplant relapse indicate higher complete remission and near-complete remission rates among patients randomized to thalidomide added to dexamethasone versus dexamethasone alone. In a phase I/II study, thalidomide derivative CC-5013, with less sedative and neurotoxic effects, promoted responses in eight of 15 patients with post-transplant relapse, refractory to other salvage therapies, at dose levels of > or = 25 mg daily. Based on a profound graft-vs-myeloma effect with allografts, mini-allotransplants were evaluated in 31 high-risk patients with cytogenetic abnormalities and prior autotransplants; all nine with responsive disease and only one prior autotransplant remain disease-free and alive. Such mini-allotransplants are now offered as consolidation after one standard autotransplant to patients with cytogenetic abnormalities. The systematic application of gene expression profiling attempts to classify multiple myeloma (MM) patients according to molecular features and to dissect the genetic basis for drug sensitivity or resistance. Given the availability of an expanding treatment armamentarium (eg, thalidomide, CC-5013, the proteasome inhibitor PS-341, farnesyltransferase inhibitors, IL-6 receptor antibody, endothelial receptor inhibitor), gene expression profiling is anticipated to help in the selection of agents with the greatest probability of activity toward individualized treatment. Careful scrutiny of gene expression will also help in the identification of unrecognized targets for therapeutic intervention.

Multiple myeloma in association with sarcoidosis.
    Archives of pathology & laboratory medicine, 2002, Volume: 126, Issue:3

    The association of sarcoidosis with Hodgkin disease and non-Hodgkin lymphoma is well known. However, multiple myeloma also can occur rarely in association with sarcoidosis. We describe a patient with sarcoidosis who subsequently developed multiple myeloma. The patient was a 49-year-old woman with a 4-year history of severe, chronic, active sarcoidosis involving her lungs, lymph nodes, eyes, and bone marrow. During the initial clinical workup, a serum monoclonal paraprotein was detected and bone marrow examination revealed a slight increase in plasma cells (4%), in addition to noncaseating granulomas. Thus, the diagnoses of monoclonal gammopathy of undetermined significance and sarcoidosis were established simultaneously. She sought medical attention for her current illness when she developed low back pain and weakness of her lower extremities. Serum protein electrophoresis and immunofixation revealed a monoclonal paraprotein, immunoglobulin (Ig) G kappa type, and quantification revealed an IgG level of 46.67 g/L (normal, 5.88--15.73 g/L). Bone marrow aspiration and biopsy revealed multiple myeloma and sarcoidosis. Including this patient, 11 cases of sarcoidosis and multiple myeloma have been reported to date, including 3 patients with monoclonal gammopathy of undetermined significance preceding the onset of multiple myeloma. In this case, as in most of the cases reported previously, sarcoidosis preceded the development of multiple myeloma.

Treatment of myeloma: recent developments.

    Melphalan was the first described treatment for patients with multiple myeloma in the 1960s and is still being used in clinical practice. However, the use of melphalan in combination with prednisone resulted in a median survival of only 2-3 years. Therefore, the dose of melphalan has been intensified since then (140-200 mg/m(2)). In order to diminish treatment-related morbidity and mortality due to severe myelosuppression induced by these regimens, high-dose melphalan is currently supported with autologous stem cells. Indications for high-dose therapy and the role of further intensification by performing second or allogeneic transplantations are discussed. Furthermore, new therapeutic modalities, such as inhibitors of angiogenesis, also showing direct antiproliferative, cytokine-related and immunomodulatory effects on plasma cells (thalidomide and its newer derivatives), inhibitors of the transcription factor NF-kappa B (proteasome inhibitors) and immunotherapy are described.

Leptomeningeal relapse of multiple myeloma following allogeneic stem cell transplantation.
    Leukemia research, 2002, Volume: 26, Issue:7

    Progressive multiple myeloma may manifest features of 'de-differentiation', including a plasmablastic appearance, failure to secrete paraprotein, extramedullary involvement, and resistance to treatment. A 44-year-old woman with kappa-light chain myeloma underwent allogeneic stem cell transplantation (SCT). Twenty months later she developed paraspinal plasmablastic myeloma in the absence of paraprotein in urine or myeloma in the marrow. The paraspinal masses responded to chemotherapy. At 30 months she developed myelomatous meningitis, which proved resistant to intrathecal chemotherapy, irradiation, and donor lymphocyte infusion (DLI). The leptomeningeal disease led to death at 38 months. This is the first report of leptomeningeal relapse of myeloma after allografting.

Multiple myeloma in elderly patients: presenting features and outcome.
    European journal of haematology, 2001, Volume: 66, Issue:1

    Few studies have been performed regarding multiple myeloma (MM) in elderly patients. We report a retrospective series of 130 unselected patients with MM aged 75 yr or more at diagnosis. Presenting features were identical to those reported in younger patients, except for a higher rate of infection. Heavy comorbidity was characteristic of unselected geriatric patients. Ninety-four patients received conventional chemotherapy. The response rate was 62%. Treatment toxicity was mild. Median survival was 22 months. Durie-Salmon (DS) clinical stages II and III MM were severe and often led to death, while significantly more patients with DS stage I MM died from unrelated causes (p<0.0001). Univariate analysis showed that age > or = 85 yr, performance status > or = 2, creatinine level > or = 120 micromol/l, beta 2 microglobulin level > 4 mg/l, C-reactive protein level > 6 mg/l, platelet count < 100 x 10(9)/l, presence of infection and lack of response to chemotherapy were adverse prognostic factors for survival. In Cox multivariate regression analysis, age > or = 85 yr (p<0.0001), performance status > or = 2 (p<0.0001) and creatinine level > or = 120 micromol/l (p<0.0001) were independent factors in predicting short survival. This study provides evidence that in patients with symptomatic MM age should not be considered as a major obstacle to active treatment. Prospective clinical trials are needed in this population of patients and should include an assessment of quality of life.

Immunomodulating anticancer alkylating drugs: targets and mechanisms of activity.
    Current drug targets, 2001, Volume: 2, Issue:2

    CY and L-PAM potentiated specific anti-tumor response in addition to their killing effect. The immunomodulating effect of a low dose of either CY or L-PAM was expressed in mice bearing large s.c. MOPC-315 plasmacytoma tumors. Cured mice were resistant to a challenge dose of the syngeneic tumor and their spleens contained specific cytotoxic T cells. Induction of specific anti-tumor response by a low dose of alkylating drugs was due to expression of "latent anti-tumor" capability. This fitted with the conception that "suppressed concomitant immunity" occurring in tumor-bearing animals can be activated. The immunomodulating activity of alkylating drugs was related to enhancement of T-cell functions:impairment of suppressor T-cell activity,enhancement of effector T-cell activity and increase in production of cytokines at the tumor site. The target tumor killing activity of a low dose alkylating drug was dissociated from its immunomodulating activity by treating mice bearing a tumor resistant to an alkylating drug. A low dose of CY had an immunomodulating effect in human cancer such as reduction of ConA-induced suppressor cell activity in melanoma, some improvement in addition to use of melanoma vaccine, and potentiation of DTH in cancer patients. The immunomodulating effect of alkylating drugs suggest that their use might be beneficial not only for killing tumor cells but also for promoting specific anti-tumor immune response.

Standard-dose therapy for multiple myeloma: The Southwest Oncology Group experience.
    Seminars in hematology, 2001, Volume: 38, Issue:3

    We summarize the Southwest Oncology Group (SWOG) experience with standard therapy for multiple myeloma by reviewing and updating data from seven consecutive SWOG trials. Some modest progress has been made since the introduction of melphalan and prednisone (MP) for induction therapy, using regimens that involve vincristine and doxorubicin, and which save alkylating agents for possible later high-dose therapy. For maintenance, it appears that prednisone plays a useful role. We demonstrate the use of the data collected in these trials with a proposed new staging system.

    This article summarizes clinical results of the Intergroupe Francophone du Myélome (IFM) trials: high-dose therapy (HDT) supported with autologous stem cells improves survival, melphalan 200 mg/m(2) is the best preparative regimen, unpurged peripheral blood stem cells (PBSC) are the recommended source of stem cells to support HDT, and tandem transplants significantly improve survival. Although these results are encouraging, the current IFM 99 protocol will evaluate innovative strategies with the goal to improve long-term survival.

[Treatment of multiple myeloma in elderly patients: consensus of the Geriatric Oncology Working Group of the German Society of Hematologic Oncology and the German Society of Geriatrics].
    Onkologie, 2001, Volume: 24, Issue:4

    Treatment of Multiple Myeloma in the Elderly: Consensus of the Cooperative Group of Geriatric Oncology of the DGHO and DGG Multiple myeloma is an illness of old age. Often, in elderly people the diagnosis is delayed by the fact that bone pain, which is the most frequently presenting symptom, is not correctly interpreted because this is a common complaint in the elderly. In contrast to younger patients with multiple myeloma, elderly patients often present with infections at diagnosis. After the diagnosis is established, careful observation is very important. This applies both to patients who require still no therapy and to patients under treatment. In order to optimize the care of older patients, apart from tumor-specific investigations multidimensional geriatric assessment is helpful. This specifically applies for multiple myeloma which predisposes the patient to 'instability' and 'immobility', both belonging to the typical geriatric symptoms. Geriatric assessment may also be helpful in the selection of those elderly patients who are candidates for a possible prognosis-improving experimental intense chemotherapy. For the majority of the elderly patients in need of treatment the standard is melphalan/prednisone accompanied by one of the biphosphonates. Nevertheless, in order to improve prospects also for this group of patients, as many elderly patients as possible should be included into studies. This is the only way to compile valid recommendations for the treatment of elderly patients with multiple myeloma.

Management of patients with multiple myeloma: emphasizing the role of high-dose therapy.
    Clinical lymphoma, 2001, Volume: 2, Issue:1

    Treatment for multiple myeloma should not be given until the patient is symptomatic or at risk for the occurrence of complications of the disease. If the patient is younger than 70 years, the physician should seriously consider an autologous peripheral blood stem cell transplant. Most physicians initially administer vincristine/doxorubicin/dexamethasone (VAD) for 3 to 4 months and then collect the stem cells before exposure to alkylating agents. Following stem cell collection, one may proceed with high-dose chemotherapy and then infusion of the stem cells, or one can administer alkylating agents until a plateau is reached and delay transplantation until progressive disease occurs. There is no difference in overall survival between early and late transplantation, but the former avoids the cost and inconvenience of alkylating agent therapy. Double or tandem autologous stem cell transplants may produce better results, but the evidence is not strong. Almost all patients have a relapse after an autologous stem cell transplant, so efforts are being made to prolong the response with a2-interferon or dendritic cell therapy. Allogeneic bone marrow transplantation is feasible for only 5%-10% of patients, but the mortality is high and it is curative in only a small fraction of patients. Treatment with melphalan and prednisone results in an objective response in 50%-60% of patients. Combinations of alkylating agents produce a higher response rate, but there is no survival benefit. Thalidomide produces an objective response in about one third of patients with refractory disease. It currently is being studied in conjunction with dexamethasone for conventional initial therapy.

Allogeneic transplantation for multiple myeloma: further evidence for a GVHD-associated graft-versus-myeloma effect.
    Bone marrow transplantation, 2001, Volume: 28, Issue:9

    We report a series of 37 consecutive patients with multiple myeloma (MM) who received an allograft between 1990 and 2000 at our institution. Median age was 47 years, and nearly 70% of patients were Durie-Salmon stage III. A median of five cycles of chemotherapy were given before transplant, with a median interval between diagnosis and transplant of 9.3 months. We report a nonrelapse mortality rate of 22% with a median follow-up period of 40 months, whereas complete remission (CR) rate at 12 months is estimated at 57%. Treatment failure rate and overall survival at 40 months are estimated at 52% and 32%, respectively. The number of chemotherapy cycles prior to allotransplantation achieved borderline statistical significance as a poor prognosis factor for overall survival (P = 0.05), while the presence of chronic graft-versus-host disease (cGVHD) was significantly correlated with CR achievement (P = 0.036). Our study confirms that early allografting in MM can yield toxicity rates significantly lower than those associated with historical cohorts, and supports the hypothesis that cumulative chemotoxicity has a negative influence on mortality and survival rates. More importantly, our study clearly demonstrates an association between cGVHD and CR and brings further evidence in favor of a graft-versus-myeloma effect.

Myeloma-associated systemic amyloidosis presenting as chronic paronychia and palmodigital erythematous swelling and induration of the hands.
    Journal of the American Academy of Dermatology, 2000, Volume: 42, Issue:2 Pt 2

    Mucocutaneous involvement occurs predominantly in primary systemic amyloidosis as well as in myeloma-associated systemic amyloidosis. It is rarely observed in other types of amyloidoses. Signs of such involvement may aid in the early diagnosis of the disease process. Herein, we describe a 64-year-old white male patient with myeloma-associated systemic amyloidosis in whom the disease presented with unique cutaneous lesions consisting of chronic paronychia and palmodigital erythematous swelling and induration of the hands. Following weekly regimens with prednisone (20 mg/day) and melphalan (2 mg/day) administered every 16 weeks, almost complete resolution of the cutaneous lesions was observed after 1 year of therapy. Also, in response to chemotherapy, modest regression of the myelomatous bone lesions and complete resolution of the underlying gammopathy occurred.

Autologous and allogeneic stem cell transplantation in multiple myeloma.
    Bone marrow transplantation, 2000, Volume: 25 Suppl 2

    Multiple myeloma is still an incurable disease. The standard conventional chemotherapy comprises melphalan and prednisone (MP). Combination chemotherapy regimens could not improve the median survival of 36 months observed with MP. In the French IFM90 study, HD therapy with TBI plus melphalan 140 mg/m2 was shown to prolong overall survival and progression-free survival compared to conventional treatment. Nonetheless, most patients eventually succumb due to disease progression. Allogeneic transplantation may induce long-term remissions and even cure, but is hampered by a high transplantation-related mortality (TRM). Currently, efforts are made to reduce this TRM and to evaluate the graft-versus-myeloma effect.

Treatment of multiple myeloma.
    Haematologica, 1999, Volume: 84, Issue:1

    Multiple myeloma (MM) accounts for about 10% of all hematologic malignancies. The standard treatment with intermittent courses of melphalan and prednisone (MP) was introduced more than 30 years ago and, since then there has been little improvement in event-free and overall survival (EFS & OS). The aim of this article is to review: 1) the role of initial chemotherapy (ChT), maintenance treatment with alpha-interferon and salvage ChT, 2) the results of high-dose therapy (HDT) followed by allogeneic or autologous stem cell transplantation (allo-SCT and auto-SCT), and 3) the most important supportive measures.. The authors of this review have been actively working and contributing with original investigations on the treatment of MM during the last 15 years. In addition, the most relevant articles and recent abstracts published in journals covered by the Science Citation Index and Medline are also reviewed.. The importance of avoiding ChT in asymptomatic patients (smoldering MM) is emphasized. The criteria and patterns of response are reviewed. MP is still the standard initial ChT with a response rate of 50-60% and an OS of 2-3 years. Combination ChT usually increases the response rate but does not significantly influence survival when compared with MP. Exposure to melphalan should be avoided in patients in whom HDT followed by auto-SCT is planned, in order to not preclude the stem cell collection. The median response duration to initial ChT is 18 months. Interferon maintenance usually prolongs response duration but in most studies does not significantly influence survival (a large meta-analysis by the Myeloma Trialists' Collaborative Group in Oxford is being finished). In alkylating-resistant patients, the best rescue regimens are VBAD or VAD. In patients already resistant to VBAD or VAD and in those in whom these treatments are not feasible we recommend a conservative approach with alternate day prednisone and pulse cyclophosphamide. While HDT followed by autotransplantation is not recommended for patients with resistant relapse, patients with primary refractory disease seem to benefit from early myeloablative therapy. Although results from large randomized trials are still pending in order to establish whether early HDT intensification followed by auto-SCT is superior to continuing standard ChT in responding patients, the favorable experience with autotransplantation of the French Myeloma Intergroup supports this approach. However, although the complete response rate is higher with intensive therapy, the median duration of response is relatively short (median, 16 to 36 months), with no survival plateau. There are several ongoing trials comparing conventional ChT with HDT/autoSCT in order to identify the patients who are likely to benefit from one or another approach. With allo-SCT there is a transplant-related mortality ranging from 30 to 50% and also a high relapse rate in patients achieving CR. However, 10 to 20% of patients undergoing allo-SCT are long-term survivors (> 5 years) with no evidence of disease and, consequently, probably cured. The use of allogeneic peripheral blood stem cells (PBSC) in order to speed the engraftment and also the use of partially T-cell depleted PBSC which can decrease the incidence of graft-versus-host disease are promising approaches. In the setting of allo-SCT, donor lymphocyte infusion is an encouraging strategy in orde

    Since 1983 an increasing number of clinical trials have used high-dose melphalan with or without autologous stem cell support in patients with multiple myeloma. It has been shown that high-dose therapy including high-dose melphalan may be considered as the treatment of choice in newly diagnosed patients. The purpose of this report is to review and summarize the clinical information on IV high-dose melphalan in patients with multiple myeloma and to examine potential areas of future investigation.

Effect of high-dose melphalan and peripheral blood stem cell transplantation on renal function in patients with multiple myeloma and renal insufficiency: a case report and review of the literature.
    Annals of hematology, 1999, Volume: 78, Issue:4

    Multiple myeloma with IgG-lambda monoclonal gammopathy and severe renal impairment with light-chain deposit disease was diagnosed in a 51-year-old man. Following conventional therapy with VAD (vincristine, adriamycin, dexamethasone) a partial remission was achieved. Peripheral blood stem cells (PBSC) were then collected following mobilization with cyclophosphamide and recombinant human granulocyte colony-stimulating factor and enriched for CD34-positive cells by immunoaffinity column. Fourteen months after diagnosis high-dose melphalan was given, followed by infusion of CD34-positive PBSC. Aside from mild oral mucositis and trigonitis, high-dose therapy was tolerated well. After he underwent PBSC transplantation his renal function improved, and the patient has been in in continuous complete remission for 1 year. Thus, high-dose chemotherapy can be safely administered to patients with multiple myeloma and severe renal impairment. Our findings confirm previous reports summarized in the current presentation.

Patients with multiple myeloma may safely undergo autologous transplantation despite ongoing RSV infection and no ribavirin therapy.
    Bone marrow transplantation, 1999, Volume: 24, Issue:5

    Respiratory syncytial virus (RSV) has been reported as a cause of death among autologous peripheral blood stem cell (ASCT) and marrow recipients and recommendations for therapy with aerosolized ribavirin plus intravenous immunoglobulin (IVIG) made. This therapy is expensive, may be toxic, and causes a significant disruption of patient care. The purpose of this study was to evaluate the morbidity and mortality of RSV infections in patients with multiple myeloma undergoing ASCT without ribavirin therapy. During the months of February-April 1997, 10 consecutive patients (median age 57 years, seven males) with advanced and heavily pretreated myeloma underwent ASCT while having active RSV upper respiratory tract infection. After melphalan (200 mg/m2), all patients became neutropenic (<1000 cells/mm3) for a median of 7 days. Ribavirin was not given to any patient. No patient developed lower respiratory tract infection, required transfer to intensive care or died at a median follow-up of 8 months. One patient developed tracheobronchitis requiring oxygenation by nasal cannula. No delay in the treatment of the underlying myeloma was incurred. RSV infection may not necessarily be a contraindication for ASCT or an indication for therapy with aerosolized ribavirin. Additional studies are needed to confirm our preliminary findings.

Therapeutic management of hematological malignancies in elderly patients. Biological and clinical considerations. Part IV: Multiple myeloma and Waldenström's macroglobulinemia.
    Aging (Milan, Italy), 1998, Volume: 10, Issue:1

    Following recent data on multiple myeloma (MM) in the literature, a possible model of myeloma development, involving different cytokine signals, is advanced, and the prognostic significance of two principle staging systems is evaluated. Different therapeutic approaches to MM have been employed, consisting of either treatment with only melphalan and prednisone, or combination chemotherapy, especially in patients with a poor prognosis. However, for the initial therapy, melphalan plus prednisone in doses that compensate for individual variation in drug absorption still appears the best choice in the vast majority of MM patients. The main clinical and hematological features which distinguish Waldenström's macroglobulinemia from MM are described, as are the criteria which should be used in choosing the most appropriate treatment based, when necessary, on chemotherapy with standard alkylating agents, as well as on the new nucleoside analogues, and repeated courses of plasmapheresis.

Combination chemotherapy versus melphalan plus prednisone as treatment for multiple myeloma: an overview of 6,633 patients from 27 randomized trials. Myeloma Trialists' Collaborative Group.
    Journal of clinical oncology : official journal of the American Society of Clinical Oncology, 1998, Volume: 16, Issue:12

    To compare combination chemotherapy (CCT) versus melphalan plus prednisone (MP) as treatment for multiple myeloma.. In a collaborative worldwide overview of randomized trials of CCT versus MP, individual patient data on 4,930 patients from 20 trials were analyzed, with the addition of published data on a further 1,703 patients from seven trials. The main outcome measure was mortality, with response and recurrence rates being subsidiary end points.. Taking all of the trials together, response rates were significantly higher with CCT than with MP (60.0% v 53.2%; P < .00001, two-tailed). There was no evidence of any difference in mortality between CCT and MP, with a nonsignificant 1.5% reduction in death rate in favor of CCT (P = .6, two-tailed). There is heterogeneity of design between the trials, but subgroup analyses by type of CCT or by dose-intensities of CCT, of melphalan, or of prednisone did not identify any particular forms of therapy that were either clearly beneficial or clearly adverse. Similarly, analysis of the presentation features of the patients did not find any categories in which CCT differed significantly from MP in its effects on mortality; in particular, there was no evidence that poor-risk patients benefited more from CCT.. This overview found no difference, either overall or within any subgroup, in mortality between CCT and MP. In terms of survival, these therapeutic options, as tested in the trials considered, are approximately equivalent.

Diagnosis, prognosis, and standard treatment of multiple myeloma.
    Hematology/oncology clinics of North America, 1997, Volume: 11, Issue:1

    The diagnosis of multiple myeloma (MM) is often difficult; most patients present with asymptomatic gammopathy. The only findings that confirm a diagnosis of MM are an elevation in the M-component or extension of the lytic bone lesions that are the hallmark of the disease. Tests that delineate plasma cell biology, such as plasma cell proliferation rate, are helpful; magnetic resonance imaging can disclose bone marrow lesions leading to subsequent osteolytic disease. After the diagnosis of MM has been established and prognostic factors identified, the appropriate therapy can be determined. Melphalan and prednisone are no longer considered to be the "gold standard" of therapy. In fact, this approach is suitable for less than half of patients with myeloma. This article presents guidelines for standard treatment options and examines the efficacy of new high-dose chemotherapy approaches.

    Since the introduction of melphalan, little progress has be obtained in the treatment of multiple myeloma. Complete remission is rarely achieved with classical single-drug or combined chemotherapy protocols: median survival remains low at 2 to 3 years. A NEW APPROACH: High-dose melphalan therapy with hemopoietic stem cell support it a new approach providing promising results. There is a dose effect and 70 to 80% of naive patients, at the cost of severe prolonged aplasia, respond to high-dose melphalan. HEMATOPOIETIC SUPPORT: Allogeneic or autologous bone marrow or blood stem cell grafts are used. Peripheral blood autographs can be used in most patients; contamination with tumoural cells is generally lower. The period of aplasia after chemotherapy and hematopoietic autograft is relatively short. MAIN INDICATIONS: For most authors, high-dose melphalan should be reserved for younger patients with active myeloma: complete remission is achieved in 20 to 30% of cases although relapse still occurs. Other techniques under study (several sequences of high-dose sessions, reduction of graft contamination) should help improve results.

A case of primary hyperparathyroidism accompanying multiple myeloma.
    Endocrine journal, 1997, Volume: 44, Issue:1

    We report a case of 77-year-old woman who presented with lumbago and hypercalcemia. Multiple myeloma (MM) was first diagnosed by serum protein electrophoresis and bone marrow aspiration, but intact parathyroid hormone (intactPTH) was also found to be high in the presence of persistent hypercalcemia with anorexia and nausea. After lowering serum calcium with bisphosphonate administration, parathyroidectomy was performed. Upon histologic examination, the tumor was determined to be parathyroidal chief-cell hyperplasia and the patient was treated with melphalan and prednisolone. The relationship between MM and primary hyperparathyroidism (I degree HPT) remains unknown. Although the co-existence of MM and I degree HPT was reported in 12 reports from various parts of the world, there was only 1 report in Japan. The present case is an example of successful treatment for a complicated disorder, and suggests that patients suffering from bone pain or hypercalcemia need to be examined both endocrinologically and hematologically.

    The association of melphalan and prednisone, introduced in the sixties, allowed a dramatic improvement in the prognosis of multiple myeloma. The subsequent evaluation of different polychemotherapeutic schedules did not ameliorate the results with respect to the melphalan-prednisone association, which remains the treatment of choice in patients older than 60-65 years. In younger patients high dose therapy allowed, in the recent years, significant improvement in terms of reduction of tumor mass and survival. The use of interferon as maintenance treatment allowed a prolongation of the response phase obtained after induction treatment. In this paper we discuss current trends in the management of multiple myeloma and related complication.

Systemic lupus erythematosus and multiple myeloma: a rare association.
    Seminars in arthritis and rheumatism, 1997, Volume: 26, Issue:6

    The association of systemic lupus erythematosus (SLE) and multiple myeloma (MM) is an uncommon event. We report the relapse of SLE in a patient with a previous history of MM, treated with chemotherapy and, subsequently, with alpha-2b interferon (alpha-2b IFN) as a maintenance therapy. The case is discussed in light of past relevant literature.. The history and clinical, laboratory and radiographic findings of the patient, as well as the subsequent therapeutic approach are discussed. In our review of the literature, journal articles are identified by Medline search.. We describe the case of a woman who developed a multiple myeloma 14 years after a diagnosis of SLE. A careful literature review confirms that the association of these two diseases has been reported only in a few cases. When the plasma cell neoplasia occurred, SLE had been quiescent for several years; the patient was treated with prednisone-melphalan and, subsequently, with alpha-2b IFN as a maintenance therapy. On admission to our department, SLE was in a relapse phase, probably because of IFN treatment. The disease was poorly responsive to steroid therapy and required the use of cytotoxic drugs.. The coexistence of SLE and MM is very rare and the possible pathogenetic mechanisms underlying this association remain unclear. The use of interferon in a patient with an autoimmune disease always invites caution.

[Progress in the treatment of multiple myeloma].
    Gan to kagaku ryoho. Cancer & chemotherapy, 1997, Volume: 24, Issue:9

    Melphalan and prednisolone (MP) have been the standard therapy for multiple myeloma for more than 25 years. Although they produce an objective response in 50-60% of patients, complete remission (CR) is rare and the median survival period is generally 24 to 30 months. Many combination chemotherapeutic agents have been used and resulted in approximately 70% objective response, but the median duration of survival has not significantly been improved. VAD regimen is effective for many patients with myeloma resistant to MP therapy. Furthermore, VAD-cyclosporin combination induces responses in approximately 40% of patients with VAD-resistant myeloma, with increased expression of the multi-drug resistant gene (MDR). Intravenous administration of high dose-melphalan also produces responses in approximately 30% of patients with myeloma resistant to VAD. Interferon-alpha therapy with an alkylating agent-glucocorticoid regimen, shows a higher response rate but similar survival time, compared with those obtained with the MP therapy alone. High-dose therapy with transplantation is promising. High-dose therapy combined with autologous bone marrow transplantation improves the response rate, event-free survival (EFS), and overall survival (OS) in patients with myeloma, demonstrated in the prospective, randomized trial by Attal et al. Total therapy by Barlogie et al. consisted of non-cross-resistant induction regimens, followed by a double autotransplantation (AT) procedure. Compared with the outcome of patients receiving standard therapy, dose intensification with double AT produces not only higher CR rates but also significantly extends EFS and OS in previously untreated patients with myeloma. The reduced mortality rate associated with transplantation, and development of new chemotherapeutic agents will lead to future improvements of the therapy for multiple myeloma.

Rationale for adjuvant idiotypic vaccination after high-dose therapy for multiple myeloma.
    Biology of blood and marrow transplantation : journal of the American Society for Blood and Marrow Transplantation, 1997, Volume: 3, Issue:3

    With conventional therapy, multiple myeloma (MM) has a poor prognosis. During the last few years, it has become clear that high-dose chemotherapy with autologous stem cell support can increase overall survival of MM patients, but further improvement in outcome is desperately needed. The monoclonal immunoglobulin (Ig) produced by the MM cells called idiotypes (Id) is a tumor-specific antigen due to unique antigenic determinants that are localized in the variable regions of the Ig molecule. Conceivably, Id immunization of MM patients in complete remission could further increase survival. Here we review the scientific basis for such Id immunization.

High-dose chemotherapy in multiple myeloma.
    Leukemia, 1997, Volume: 11 Suppl 5

    The median survival of conventionally treated patients with multiple myeloma is 3 years. Modifications of conventional chemotherapy have failed to show an improved survival rate in most randomized trials. Therapy regimens with dose-escalated alkylating agents (ie melphalan) have induced higher remission rates in comparison to conventional treatment modalities. With the support of autologous or allogeneic hematopoietic progenitor cells, it has been possible to reduce the hematoxicity of these dose-escalated treatments. The transplantation of autologous peripheral blood progenitor cells results in faster hematopoietic reconstitution with decreased high-dose therapy-related morbidity compared to autologous bone marrow. The randomized French myeloma trial and the pair-mate analysis of the results of the 'total therapy' including double autografting of the Barlogie group with data from the South Western Oncology Group (SWOG) showed a significant survival advantage for patients following autologous transplantation. Although a graft-versus-myeloma effect was described, the benefit of high-dose treatment with allogeneic transplantation is less clear, mainly due to the high transplantation-related mortality rate. In this paper, results of transplantation trials are summarized. Prognostic factors and future treatment modalities for myeloma are discussed.

    Previous reports have stressed the association between autoimmune disease and lympho-proliferative neoplasm. Here we report a patient in whom multiple myeloma developed about 30 years after the onset of rheumatoid arthritis. A 79 year-old woman with an about 30-year history of rheumatoid arthritis was admitted because of lumbago in December, 1993. Laboratory findings revealed M-proteinemia (IgA 2,380 mg/dl, IgG 728 mg/dl, IgM 51 mg/dl) and serum immunoelectrophoresis showed monoclonal IgA with lambda type light chain. Bone marrow aspirate contained 66.0% plasma cells. Serological tests of rheumatoid factor were positive. X-ray findings revealed radiolucent myelomatous foci in the skull and typical destructive changes of rheumatoid arthritis in multiple joint. From these findings, IgA lambda-type multiple myeloma with rheumatoid arthritis was diagnosed. Although the pathogenesis of the association between rheumatoid arthritis and multiple myeloma is unknown, prolonged antigenic stimulation manifested by rheumatoid arthritis is considered to be a possible pathogenetic factor in the development of multiple myeloma.

[Treatment of multiple myeloma--melphalan monotherapy after bone marrow transplantation].
    Vnitrni lekarstvi, 1996, Volume: 42, Issue:4

    Melphalan has brought the first improvement in the therapy of multiple myeloma at the beginning of the sixties. The median of survival was prolonged from several months to three years. In the following three decades new drugs were tested, but no other drug brought better results than melphalan. The comparative studies have proved, that therapy response has been reached more rapidly after polychemotherapy than monotherapy, but none of the treatment modalities differed in the survival parameters. The significance of interferon alpha for the treatment of multiple myeloma has been tested since the beginning of the eighties. Many clinical trials have brought contraverse results. The latest metaanalysis and data published by Ludwig support the indication of interferon alpha for the multiple myeloma maintenance treatment. Important progress in the therapy of multiple myeloma has been done in the nineties. High doses of alkylating cytostatics with the support of autologous peripheral blood stem cells transplantation or bone marrow transplantation enhanced the number of therapy-responses and prolonged the survival. The results of autologous transplantations are so favourable, that this procedure can be recommended as the first line treatment in suitable patients. Allogenic bone marrow transplantation is linked with many complications and therefore this method will be performed only in a limited number of patients. Trials dealing with this new therapy-trend are reviewed in this paper.

Hematopoietic stem cell transplants for multiple myeloma.
    Leukemia & lymphoma, 1996, Volume: 22, Issue:1-2

    Standard chemotherapy with melphalan-prednisone or a combination of alkylating agents has not extended the overall survival of patients with multiple myeloma during the last 30 years and strictly defined complete remissions (CR) are exceedingly rare. The early mortality with conventional therapy varies between 2 and 10 percent. A substantial increase in the dose of melphalan (100-140 mg/m2) has resulted in a 30-45% CR rate in newly diagnosed patients and an overall survival advantage of approximately 1 year. However, treatment related morbidity and mortality, due to prolonged cytopenia was unacceptably high. Based on these findings the dose intensity was further increased by either escalating melphalan to 200 mg/m2 or by adding total body irradiation, while at the same time providing stem cell support to shorten the duration of cytopenia. Autologous transplants, especially with peripheral blood stem cells and hematopoietic growth factors, can now be performed safely up to the age of 70 with a low transplant-related mortality (2-10%). A CR is attained in approximately 50% of previously untreated patients and 10-20% of refractory cases. Overall survival of newly diagnosed and refractory patients treated with autotransplants appears superior to that of patients receiving conventional chemotherapy. Therefore, autotransplantation should be considered as a treatment option in all patients with multiple myeloma at least up to the age of 65. Despite these encouraging findings, most myeloma patients ultimately relapse and the survival curves do not suggest that autotransplantation as currently performed is a curative approach in a substantial proportion of patients. Further improvement with autotransplants should be achieved by providing tumor-free grafts and by introducing post-transplantation manipulations, aimed at eradicating minimal residual disease.

Peripheral blood stem cell transplants for multiple myeloma: identification of favorable variables for rapid engraftment in 225 patients.
    Blood, 1995, Jan-15, Volume: 85, Issue:2

    Transfusion of autologous peripheral blood stem cells (PBSCs) of good quality ensures fast hematopoietic engraftment after myeloablative therapy with a decrease in procedure-related morbidity and mortality. We have analyzed variables influencing the kinetics of engraftment, and therefore reflecting the quality of PBSC collections, in 225 patients with newly diagnosed or refractory multiple myeloma (MM) who received an autotransplant in support of high dose melphalan (200 mg/m2); 132 of these patients also completed a second transplant. All PBSCs were collected before the first transplant after high-dose cyclophosphamide (6 g/m2) and hematopoietic growth factors, mainly granulocyte-macrophage colony-stimulating factor. PBSCs were administered either alone (91 patients) or with bone marrow (134 patients). A highly significant correlation was observed between the number of CD34+ cells per kilogram infused and prompt recovery of both granulocytes (P = .0001) and platelets (P = .0001). After correction for the proportion of patients with > or = 2 x 10(6)/kg CD34 PBSCs infused and with < or = 12 months of prior therapy, no difference in engraftment kinetics was seen between patients receiving PBSCs only and those also receiving bone marrow. Exposure to chemotherapy, even to < or = 6 months of alkylating agents, significantly delayed hematopoietic recovery posttransplantation. The threshold dose of CD34 cells necessary for prompt engraftment was > or = 2.0 x 10(6)/kg for patients with < or = 24 months of chemotherapy before the first transplant, whereas greater than 5 x 10(6)/kg CD34 cells were required to assure rapid recovery also in those with longer exposure. Such quantities, easily collected in the large majority of patients with shorter exposure (91%), were obtained in only 28% of patients with more than 24 months of prior chemotherapy. Rapid platelet recovery within a narrow range of time (before day 14) was almost invariably seen (94%) when greater than 5 x 10(6)/kg CD34 cells were infused, irrespective of the duration of prior therapy, whereas the range widened progressively when less CD34 cells were infused. In the absence of CD34 measurements, fast recovery of platelets to greater than 50 x 10(9)/L within 14 days after high-dose cyclophosphamide and < or = 12 months of prior chemotherapy were the best predictors of early engraftment. Prudent use of stem cell-damaging agents, such as melphalan and nitrosoureas, is recommended in MM patients who might b

High-dose intravenous melphalan: a review.
    Journal of clinical oncology : official journal of the American Society of Clinical Oncology, 1995, Volume: 13, Issue:7

    To review the clinical pharmacology and clinical trials that have used intravenous (IV) high-dose melphalan (HDM).. We reviewed the mechanism of action, clinical pharmacology, and clinical studies of HDM with and without autologous bone marrow support (ABMT) or peripheral-blood progenitor cells (PBPCs) in the following disease areas: myeloma, ovarian cancer, malignant lymphoma, breast cancer, neuroblastoma, Ewing's sarcoma, and acute leukemia.. HDM has a distribution half-life (t1/2 alpha) of 5 to 15 minutes and an elimination half-life (t1/2 beta) of 17 to 75 minutes at doses of 140 to 180 mg/m2, with significant intrapatient variability. At these doses, a wide range of areas under the concentration/time curve (AUC) have been reported, ie, 146 to 1,515 mg/min/mL. HDM has significant clinical activity in patients with multiple myeloma in relapse or when used as consolidative therapy in relapsed ovarian cancer, relapsed Hodgkin's disease, breast cancer, and relapsed neuroblastoma. Additional studies are required to determine the activity of HDM in Ewing's sarcoma or acute leukemia. Toxicities of HDM include myelosuppression, moderate nausea and vomiting, moderate to severe mucositis and diarrhea, and, infrequently, hepatic venoocclusive disease.. HDM has become an established and effective salvage regimen for children with relapsed neuroblastoma, as well as an effective consolidative treatment for children with high-risk disease (stage IV). HDM is emerging as an active and effective mode of treatment in patients with stage II and III myeloma. The favorable toxicity profile of HDM and the availability of PBPCs allows for repetitive therapy.

[Diagnosis and therapy of multiple myeloma: current aspects].
    Schweizerische medizinische Wochenschrift, 1995, Mar-18, Volume: 125, Issue:11

    The crucial first step in management of multiple myeloma is to be certain regarding the diagnosis. Multiple myeloma must be distinguished from monoclonal gammopathy of undetermined significance (MGUS) and smoldering multiple myeloma. Therapy should be administered to patients with advanced and active myeloma involving anemia, osteolysis or renal failure. Chemotherapy with a single agent (melphalan) is the preferred initial treatment for overt, symptomatic multiple myeloma. Cytostatic drug combinations produce a higher response rate, but survival and remission during are the same compared with melphalan/prednisone therapy. However, in patients with renal failure and/or poor prognostic factors (advanced stage, elevated beta 2-microglobulin, high bone marrow plasma cell labeling index, high levels of C-reactive protein and lactate dehydrogenase and/or nodular pattern of bone marrow infiltration), combined treatment with adriamycin, vincristine and prednisone should be administered to prevent nephrotoxicity and attain a rapid paraprotein decrease. Alpha interferon treatment as maintenance seems to prolong the duration of the plateau state after response to chemotherapy, but apparently does not prolong survival. Allogeneic bone marrow transplantation involves significant early mortality (50%); the risk of graft versus host disease, infections and renal failure is a problem, and relapse is common. High dose chemotherapy followed by autologous bone marrow transplantation or peripheral blood stem cell reinfusion may prolong survival and free time to progression, but, to date, there are no indications of cure. This therapeutic procedure, therefore, should be considered for randomized trials for young patients with poor prognostic factors.

Plasma cell dyscrasia with marrow fibrosis. A reversible syndrome mimicking agnogenic myeloid metaplasia.
    Cancer, 1994, Feb-01, Volume: 73, Issue:3

    The interrelation between plasma cell dyscrasia and myelofibrosis or agnogenic myeloid metaplasia (AMM) is unclear. The existence of two distinct syndromes has been proposed: (1) plasma cell dyscrasia associated with simple marrow fibrosis caused by the secretion of lymphokines and (2) myeloma coexisting with AMM representing two distinct clonal diseases.. The authors report the case of a 68 year-old man seen initially with severe anemia, massive splenomegaly, a leuko-erythroblastic blood morphology, and myelofibrosis coexisting with massive bone marrow infiltration with IgA lambda-producing plasmacytoid cells.. Cyclic therapy with vincristine, carmustine, cyclophosphamide, melphalan, and prednisone resulted in clinical remission of the myeloma lasting for 2 years and complete resolution of all the clinical features resembling AMM.. The authors' observations and the report of two other patients in whom remission of AMM has been observed after myeloma treatment underline the broad spectrum of secondary abnormalities ranging from moderate bone marrow fibrosis to the full clinical expression of a syndrome closely mimicking AMM. These secondary abnormalities are potentially reversible even in the presence of advanced bone marrow fibrosis and massive splenomegaly.

    The author presents part II of his review on the treatment of refractory myeloma. Treatment with large doses of melphalane, 140 mg/m2, was associated with a high death rate and therefore it is used nowadays only in combination with autologous transplantation or treatment with leucocytic growth factors (GM-CSF and G-CSF). Medium doses of melphalane (25 mg/m2 to 70 mg/m2) are tolerated better and are one of the possible approaches. Another possible therapeutic procedure is whole-body irradiation. The advantage of extensive irradiation is rapid regression of pain. Interferon-alpha achieves a therapeutic response in some 20% of refractory patients. Finally the author presents some data on transplantation of bone marrow in patients with multiple myeloma.

Multiple myeloma. New treatment options.
    Drugs, 1992, Volume: 44, Issue:2

    Before proceeding to treatment selection for multiple myeloma, it is important to exclude monoclonal gammopathy of unknown significance or any similar smouldering or indolent type of myeloma not requiring immediate chemotherapy. In patients with active myeloma, pretreatment prognostic classification is important for appropriate balancing of the risks and benefits of particular treatment options. For example, conventional chemotherapy such as melphalan/prednisone may be appropriate for an elderly patient with active stage III myeloma, whereas high dose chemotherapy with or without bone marrow transplantation or cytokine support may be considered for the patient under age 45 with even earlier stage disease. A variety of options are now available for patients with relapsing or resistant disease, particularly using agents with potential for reversal of multi-drug resistance. The use of interferon-alpha as maintenance following initial response to chemotherapy is important for prolongation of remission, duration and potentially survival. A variety of supportive measures are also helpful including the use of epoetin (erythropoietin) to improve refractory anaemia and bisphosphonates for the inhibition of ongoing bone resorption. With the availability of various treatment options, it has become important for patients to be evaluated by a specialist in the field.

    Recenti progressi in medicina, 1992, Volume: 83, Issue:9

    Multiple myeloma still remains a fatal disease. However, in the last months new biological and clinical informations have been provided about this disease. In particular, the immunophenotype of myeloma cells seems indicate, in some patients, a clonal involvement of a stem cell in the pathogenesis of mieloma. Moreover, new biological insights concerning the cytokine network, have revealed a probable effect of some cytokines, such as IL6, IL3, IL4. Finally, new insights in the biology of multiple myeloma have been provided by studies of molecular biology and flow cytometry. As for therapy, the best conventional induction treatment still remains to be defined. In the last years, the increased use of alpha Interferon and new therapeutic modalities, such as transplantation procedures in multiple myeloma, open new hopes toward a cure of this disease. Therefore, in the future a better knowledge of the multiple myeloma biology, associated with a wider use of new effective therapeutic approaches will certainly improve the natural course of this disease.

Multiple myeloma complicated by congestive heart failure following first administration of recombinant alpha-interferon.
    Internal medicine (Tokyo, Japan), 1992, Volume: 31, Issue:7

    A 59-year-old female was admitted to Tsukuba University Hospital and diagnosed as IgA-lambda multiple myeloma (stage IIIA). No cardiovascular disorder with the exception of minor ischemic changes in ECG was revealed before treatment. Recombinant human alpha-interferon (IFN) at a dose of 3 million units combined with melphalan and prednisolone was administrated. Sixteen hours after the first administration of IFN, IFN was suspended by the symptoms of congestive heart failure (CHF). Treatment with diuretics and catecholamine products showed almost complete recovery from CHF in 3 weeks. An adverse reaction to IFN was strongly suspected as the cause of CHF.

Combination chemotherapy versus melphalan and prednisolone in the treatment of multiple myeloma: an overview of published trials.
    Journal of clinical oncology : official journal of the American Society of Clinical Oncology, 1992, Volume: 10, Issue:2

    A meta-analysis was performed to compare survival after treatment with melphalan and prednisolone (M + P) with that after combination chemotherapy (CCT) in patients with multiple myeloma.. Meta-analysis was performed on 18 published trials comprising 3,814 patients comparing M + P with CCT. Two-year survival percentages with observed and expected deaths at 2 years were calculated for each trial, and the overview methodology was applied to these figures.. Overall results from the 18 trials suggest that there is no difference in efficacy between the two treatments. This finding, however, masks a highly significant correlation between 2-year survival rates for M + P-treated patients in individual studies and the difference between the M + P and CCT 2-year survival rates for that study (r = .69; P = .0008). In separate overviews, those studies with a high M + P 2-year survival rate showed a survival difference in favor of M + P (P = .02), whereas those with a low rate suggested a difference in favor of CCT (P V .07). Comparison of the 2-year survival rates in the M + P treatment arms of each of the studies with available data showed an inverse correlation between survival and the proportion of patients with either poor performance status (P less than .001) or immunoglobulin A (IgA) M band (P = .02).. These results imply that M + P is superior for patients with an intrinsically good prognosis and inferior for those patients with a poor prognosis. If reliable prognostic factors can be established for this disease, they could be used to select therapy for individual patients.

Standard chemotherapy for myelomatosis: an area of great controversy.
    Hematology/oncology clinics of North America, 1992, Volume: 6, Issue:2

    L-PAM and prednisone (MP) has been challenged, almost from the start, by combination chemotherapy (CT) with its strong theoretic backing, as the standard chemotherapy for multiple myeloma. In effect, the two contestants were really evenly matched. Unfortunately, neither of them has been able to provide a satisfactory weapon against this remarkably resistant disease. This lack of an effective therapy has stimulated both the search for new strategies and an ongoing controversy. MP remains the standard induction chemotherapy for MM. Nevertheless, in several clinical conditions CT is preferable. The 18% of MM patients who show at presentation acute or chronic renal failure may be safely treated with regimens including cytotoxic drugs with a nonrenal excretion, such as doxorubin. Moreover, low-dose oral melphalan is not recommended for young patients in the event of their enrollment in high-dose programs. The standard chemotherapy for MM will continue to be an area of great controversy until a new treatment strategy proves to be clearly superior in large randomized studies.

Drug resistance in myeloma: mechanisms and approaches to circumvention.
    Hematology/oncology clinics of North America, 1992, Volume: 6, Issue:2

    Chemotherapy remains the mainstay in the treatment of multiple myeloma today. Despite improvements in survival and quality of life that can be attributed to advances in chemotherapeutic treatment, multiple myeloma remains an incurable disease. The development of drug resistance accounts for most treatment failures. Mechanisms of resistance for chemotherapeutic agents occur at the cellular level. Some of these mechanisms are unique for a given individual drug, whereas other mechanisms may confer resistance to a wide variety of agents. Important steps for improving treatment include investigating the resistance mechanisms, developing methods to identify drug-resistant cells, and preventing or circumventing drug resistance once it occurs.

New treatment strategies for multiple myeloma.
    American journal of hematology, 1990, Volume: 35, Issue:3

    During the past 5 years, several new treatments and strategies have been developed for patients with multiple myeloma. For patients with disease resistant to standard therapies, these include the VAD regimen, dexamethasone alone, high-dose melphalan, and intensive chemoradiotherapy with bone marrow transplantation. Alpha interferon appears to have its greatest potential as part of early induction therapy or during remission maintenance. The role of hemopoietic growth factors or blood stem cells in support of high-dose therapy and drugs that may overcome multiple drug resistance continues under study. A sequence of non-cross resistant therapies early in the disease course seems worthy of investigation, especially in patients at high risk for early relapse.

[Therapy of multiple myeloma and its complications].
    Recenti progressi in medicina, 1990, Volume: 81, Issue:10

    A dramatic improvement in the prognosis of multiple myeloma has been obtained since treatment with alkylating agents was introduced in the sixties. In recent years much effort has been made to ameliorate the obtained results by employing polychemotherapy schedules of treatment. However, no significant improvements with respect to the conventional melphalan-prednisone treatment, in terms of survival duration, have been observed. New therapeutic approaches, such as the use of biological response modifiers and the autologous or allogeneic bone marrow transplantation offer new perspectives for multiple myeloma patients. In this paper we discuss current trends in the therapy of multiple myeloma and of related complications.

Melphalan/prednisone versus drug combinations for plasma cell myeloma.
    European journal of haematology. Supplementum, 1989, Volume: 51

    Reports of 13 prospective, randomized clinical trials comparing standard treatment with melphalan and prednisone (MP) versus various drug combinations in the treatment of myeloma patients are presented. These studies reveal that patients with Durie-Salmon Stage III disease respond significantly more frequently to MP and drug combinations than those with Stage I and II. Drug combinations may be more effective in inducing objective responses. The response rates were significantly better for the drug combinations in 3 of the 13 comparisons. There was little evidence that either form of treatment was superior in prolonging survival, for in one study the patients treated with a drug combination lived significantly longer than those treated with MP, while in another the reverse was true, and there was no difference in the survival of the two groups in the remaining 11 studies. In the Vth MRC myelomatosis trial, patients treated with a combination of adriamycin, carmustine, cyclophosphamide and melphalan are living significantly longer than those treated with melphalan alone, and this survival advantage persists after correction for the most important prognostic factor, beta 2 microglobulin. Attempts to increase the intensity of treatment by using syngeneic, allogeneic or autologous marrow transplantation to rescue patients following otherwise lethal chemoradiotherapeutic treatments, have not yet demonstrated conclusively that the myeloma clone can be eliminated by this form of treatment.

High-dose chemotherapy and autologous bone marrow transplantation for myeloma.
    European journal of haematology. Supplementum, 1989, Volume: 51

    In three studies we have attempted to increase the complete remission rate in a series of patients with multiple myeloma under the age of 69. A CR rate of 27% was seen in 63 patients treated with intravenous high-dose melphalan 140 m/m2 with or without the addition of high-dose methyl prednisolone 1 g/m2 for 5 days (in 22 patients). In a third study a CR rate of 50% was seen in 50 patients treated in a programme in which vincristine, adriamycin and methyl prednisolone was first given and patients then received high-dose melphalan 140-200 mg/m2 with an autologous bone marrow transplant where possible. Median remission duration in the first two studies was 19 months with a median survival of 5 years. A definition of complete remission in myeloma is proposed.

    A 37-year-old male patient with advanced refractory plasma cell myeloma underwent T-cell depleted bone marrow transplantation (BMT) after 7 years of active disease previously treated with combination chemotherapy and irradiation. After the BMT there was marked clinical improvement and the patient is currently in good clinical condition two years after the BMT was performed. However, residual myeloma cells are still seen in the marrow and stable levels of paraprotein are still present in the serum. No GVHD was encountered after BMT. The problems of BMT in myeloma are discussed with a review of the current pertinent literature.

High-dose chemoradiotherapy with syngeneic bone marrow transplantation for multiple myeloma: a case report and literature review.
    American journal of hematology, 1987, Volume: 26, Issue:2

    We had the opportunity to treat a patient with progressive heavily pretreated multiple myeloma with high-dose chemoradiotherapy with hematopoietic rescue by syngeneic bone marrow transplantation. The patient was a 53-year-old male who had previously received melphalan, prednisone, 1,3-bis (2-chloroethyl)-l-nitrosourea (BCNU), vincristine, and standard radiation therapy. At the time of bone marrow transplantation, he had increasing bone pain, increasing M-protein (IgG kappa), and a bone marrow diagnostic of myeloma. The transplant regimen consisted of cyclophosphamide, 60 mg/kg intravenously for 2 days, and total body irradiation--1,200 rads given as 200-rad fractions, twice daily for three days. The transplant course was complicated by confusion, herpes simplex mucositis, fever, and two episodes of idiopathic diffuse interstitial pneumonia. Over the next 2 years the patient did well and was in immunologic and bone marrow complete remission. Unfortunately, 3 years after treatment, the myeloma relapsed with detectable M-protein. Three and one-half years after transplant, clinical relapse occurred with bone pain and lytic lesions necessitating additional radiation and chemotherapy. Salvage therapy has produced clinical improvement and the patient is alive almost 4 years from transplant and almost 7 years from diagnosis. Although intense chemoradiotherapy did not cure this patient, substantial control of a refractory tumor was observed. This case, together with other cases of intense therapy for myeloma which are reviewed in this paper, support the concept of high-dose therapy and should foster further investigation of high-dose therapy.

Multiple myeloma: current therapy and a glimpse of the future.
    Scandinavian journal of haematology, 1985, Volume: 35, Issue:1

    Patients with benign monoclonal gammopathy or smouldering multiple myeloma should not be treated. The plasma cell labelling index utilizing tritiated thymidine or a monoclonal antibody to 5-bromo-2-deoxyuridine is helpful in differentiating patients with benign monoclonal gammopathy or smouldering myeloma from those with overt myeloma. Although combinations of chemotherapeutic agents seem to produce a greater number of objective responses than does melphalan-prednisone, a significant difference in survival has not been proved. Possibilities for future treatment include chemotherapy with large intravenous doses of melphalan, very small doses of cyclophosphamide or melphalan, the administration of hydroxyurea before chemotherapy, combination of interferon with alkylating agents, autologous bone marrow transplantation, and improvement of the soft-agar colony-forming assay for myeloma cells. The therapeutic use of monoclonal antibodies to plasma cell antigens may be possible in the future. Much more needs to be learned about the biologic basis of myeloma before real progress can be made.

Immunoglobulin E (IgE) multiple myeloma: a case report and review of the literature.
    The American journal of medicine, 1981, Volume: 70, Issue:5

    A case of immunoglobulin E (IgE) myeloma with clinical features of "classic" myeloma is presented. Skeletal roentgenograms showed osteoporosis and compression fractures of the vertebrae but no osteosclerosis. Protein analyses revealed an M component of the IgE kappa type with a concentration of 3.1 g/dl. Although morphologic examination revealed that the plasma cells were not so differentiated, well-developed Golgi apparatus and abundant rough-surfaced endoplasmic reticulum were observed. An indirect immunofluorescence technique showed characteristic apple green fluorescence. The E myeloma protein of our patient had no antibody activity. Treatment with melphalan or cyclophosphamide resulted in a decrease in the serum IgE level and in the level of Bence Jones protein in the urine. The clinical and laboratory features of IgE myeloma were summarized and compared with those of other classes of myeloma.

    The basic pathologic process in multiple myeloma is the neoplastic proliferation of a single clone of plasma cells. Although the events which trigger autonomous cell growth are not well understood, the secretion of an M component, a serum or urinary immunoglobulin molecule or a light chain fragment by the vast majority of myeloma cells has provided a biologic marker which has greatly facilitated the study of this disease Some of the more recent clinical concepts which have evolved from studies on the plasma cell and the immunoglobulin molecule are discussed.

    Klinische Wochenschrift, 1979, Aug-01, Volume: 57, Issue:15

    The results of a follow-up study of 112 patients with multiple myeloma are presented. Three of these patients developed acute leukaemia during the respective period of clinical observation (maximum: 11 years)--one case of acute myeloblastic leukaemia, myelomonocytic leukaemia and erythroleukaemia, respectively. For estimating the incidence of acute leukaemia in the presence of multiple myeloma an extended life table method was applied. On the basis of our data this method gave a probability of 5.9% for a patient to develop acute leukaemia at any time after the diagnosis of multiple myeloma. In a statistical discussion this result is considered to confirm the assumption of a highly increased AL-risk in patients with multiple myeloma. In a survey of the literature some important data of 100 cases with the association acute leukaemia--multiple myeloma are reported.

    A case of fatal pulmonary fibrosis and atypical epithelial proliferation (AEP) in a patient with multiple myeloma treated with melphalan is presented. Review of 10 other autopsied patients with myeloma treated with melphalan but no thoracic radiation, other cytotoxic agents, or highdose oxygen therapy revealed one other patient who died with extensive pulmonary fibrosis and AEP. Four other patients with AEP not associated with pneumonitis or fibrosis were also found, while no such changes were found in 11 autopsy controls or 11 patients with myeloma who did not receive cytotoxic agents. Melphalan should be added to the growing list of agents capable of causing severe fibrotic pulmonary reactions.

The action of antitumor agents: a double-edged sword?
    Medical and pediatric oncology, 1977, Volume: 3, Issue:2

    Although cytotoxic immunosuppressive agents play an unquestionably useful role in treating many neoplastic and non-neoplastic disorders, there is accumulating evidence that the toxicity associated with their use is considerable. The therapeutic successes obtained with antitumor agents have led to increases in the life span of cancer patients, but have also provided the opportunity for this toxicity to become manifest. A search of the available literature was carried out, with emphasis on cases in which a malignancy developed in patients following chemotherapy for either neoplastic or non-neoplastic (e.g., renal transplantation, psoriasis) conditions; particular focus was given to the incidence of acute myelogenous leukemia in various groups of Hodgkin's disease and multiple myeloma patients. That patients with nonmalignant conditions treated with cytotoxic immunosuppressive agents are also at increased risk of developing a malignancy raises the possibility that these agents may have oncogenic potential. Therefore, one may be faced with the paradox that the patients benefiting most from chemotherapy may be at highest risk of suffering its consequences.

Phase 1 Study of the Combination of Escalated Total Marrow Irradiation Using Helical Tomotherapy and Fixed High-Dose Melphalan (140 mg/m²) Followed by Autologous Stem Cell Transplantation at First Relapse in Multiple Myeloma.
    International journal of radiation oncology, biology, physics, 2023, 03-01, Volume: 115, Issue:3

    A second intensification is an option at first relapse in multiple myeloma (MM) after more than 36 months of initial remission. Many conditioning regimens have been tested, with or without total body irradiation (TBI). Recently, it was found that TBI could be replaced by total marrow irradiation (TMI) using helical tomotherapy, with promising results.. This study was a prospective multicenter phase 1 trial that aimed to determine the maximum tolerated dose (MTD) of TMI administered in association with melphalan 140 mg/m², followed by autologous stem cell transplantation as consolidation at first relapse in MM. Four dose levels were explored: 8 Gy, 10 Gy, 12 Gy, and 14 Gy. The dose-limiting toxicity (DLT) was defined as grade 4 neutropenia >15 days, grade 4 thrombopenia >28 days, and all other grade 4 nonhematologic toxic effects except nausea, vomiting, alopecia, mucositis, and reaction to autologous stem cell infusion.. Thirteen patients were included; only 1 DLT at the third escalated dose level (12 Gy) was observed, whereas 1 patient was treated at 14 Gy with no adverse events. The MTD was not reached. The rate of acute toxicity was low: 38% of grade 3-4 diarrhea, mucositis, or unexplained fever. Regarding the lungs, the mean dose administered was systematically less than 8 Gy. After a median follow-up of 55 months, 70% of participants were alive. Of these 13 patients, 38.5% were in very good partial response and 30.8% were in complete response. Three of them were progression-free. Six patients were long survivors, still alive after 55 months of follow-up.. Total marrow irradiation provides good results with a good tolerance profile at first relapse in MM and makes it possible to increase the dose delivered to the planning target volume while sparing organs at risk. This technique could be discussed for all regimens before auto- or allo-stem cell rescue when TBI is required.

Patient-reported outcomes in relapsed/refractory multiple myeloma treated with melflufen plus dexamethasone: analyses from the Phase II HORIZON study.
    British journal of haematology, 2022, Volume: 196, Issue:3

    Relapsed/refractory multiple myeloma (RRMM) is known to have a high burden of disease and complications associated with refractoriness to prior lines of therapy. Severe pain and fatigue symptoms and impairments in physical and emotional functioning have been strongly linked to reduced health-related quality of life (HRQoL) in patients with RRMM. Assessment of patient reported-outcome measures from the pivotal, Phase II HORIZON study (OP-106; NCT02963493) in patients with RRMM (n = 64) demonstrated that melphalan flufenamide (melflufen) plus dexamethasone treatment preserved HRQoL. Patients had clinically meaningful improvements, even after eight treatment cycles, in relevant scales such as global health status/QoL, physical functioning, emotional functioning, pain, and fatigue. Patients with triple-class-refractory disease (n = 50) displayed similar improvements. Patient-reported outcome deterioration was delayed for a substantial amount of time in patients who experienced a response to melflufen plus dexamethasone treatment relative to patients who did not experience a response. These findings support the notion that treatment with melflufen plus dexamethasone may sustain or improve HRQoL over time in patients with RRMM, including in patients with triple-class-refractory disease for whom outcomes are generally worse. The clinical benefits observed in patients from the HORIZON trial are encouraging and supportive of translation into real-world practice.

Melflufen or pomalidomide plus dexamethasone for patients with multiple myeloma refractory to lenalidomide (OCEAN): a randomised, head-to-head, open-label, phase 3 study.
    The Lancet. Haematology, 2022, Volume: 9, Issue:2

    Melphalan flufenamide (melflufen), an alkylating peptide-drug conjugate, plus dexamethasone showed clinical activity and manageable safety in the phase 2 HORIZON study. We aimed to determine whether melflufen plus dexamethasone would provide a progression-free survival benefit compared with pomalidomide plus dexamethasone in patients with previously treated multiple myeloma.. In this randomised, open-label, head-to-head, phase 3 study (OCEAN), adult patients (aged ≥18 years) were recruited from 108 university hospitals, specialist hospitals, and community-based centres in 21 countries across Europe, North America, and Asia. Eligible patients had an ECOG performance status of 0-2; must have had relapsed or refractory multiple myeloma, refractory to lenalidomide (within 18 months of randomisation) and to the last line of therapy; and have received two to four previous lines of therapy (including lenalidomide and a proteasome inhibitor). Patients were randomly assigned (1:1), stratified by age, number of previous lines of therapy, and International Staging System score, to either 28-day cycles of melflufen and dexamethasone (melflufen group) or pomalidomide and dexamethasone (pomalidomide group). All patients received dexamethasone 40 mg orally on days 1, 8, 15, and 22 of each cycle. In the melflufen group, patients received melflufen 40 mg intravenously over 30 min on day 1 of each cycle and in the pomalidomide group, patients received pomalidomide 4 mg orally daily on days 1 to 21 of each cycle. The primary endpoint was progression-free survival assessed by an independent review committee in the intention-to-treat (ITT) population. Safety was assessed in patients who received at least one dose of study medication. This study is registered with ClinicalTrials.gov, NCT03151811, and is ongoing.. Between June 12, 2017, and Sept 3, 2020, 246 patients were randomly assigned to the melflufen group (median age 68 years [IQR 60-72]; 107 [43%] were female) and 249 to the pomalidomide group (median age 68 years [IQR 61-72]; 109 [44%] were female). 474 patients received at least one dose of study drug (melflufen group n=228; pomalidomide group n=246; safety population). Data cutoff was Feb 3, 2021. Median progression-free survival was 6·8 months (95% CI 5·0-8·5; 165 [67%] of 246 patients had an event) in the melflufen group and 4·9 months (4·2-5·7; 190 [76%] of 249 patients had an event) in the pomalidomide group (hazard ratio [HR] 0·79, [95% CI 0·64-0·98]; p=0·032), at a median follow-up of 15·5 months (IQR 9·4-22·8) in the melflufen group and 16·3 months (10·1-23·2) in the pomalidomide group. Median overall survival was 19·8 months (95% CI 15·1-25·6) at a median follow-up of 19·8 months (IQR 12·0-25·0) in the melflufen group and 25·0 months (95% CI 18·1-31·9) in the pomalidomide group at a median follow-up of 18·6 months (IQR 11·8-23·7; HR 1·10 [95% CI 0·85-1·44]; p=0·47). The most common grade 3 or 4 treatment-emergent adverse events were thrombocytopenia (143 [63%] of 228 in the melflufen group vs 26 [11%] of 246 in the pomalidomide group), neutropenia (123 [54%] vs 102 [41%]), and anaemia (97 [43%] vs 44 [18%]). Serious treatment-emergent adverse events occurred in 95 (42%) patients in the melflufen group and 113 (46%) in the pomalidomide group, the most common of which were pneumonia (13 [6%] vs 21 [9%]), COVID-19 pneumonia (11 [5%] vs nine [4%]), and thrombocytopenia (nine [4%] vs three [1%]). 27 [12%] patients in the melflufen group and 32 [13%] in the pomalidomide group had fatal treatment-emergent adverse events. Fatal treatment-emergent adverse events were considered possibly treatment related in two patients in the melflufen group (one with acute myeloid leukaemia, one with pancytopenia and acute cardiac failure) and four patients in the pomalidomide group (two patients with pneumonia, one with myelodysplastic syndromes, one with COVID-19 pneumonia).. Melflufen plus dexamethasone showed superior progression-free survival than pomalidomide plus dexamethasone in patients with relapsed or refractory multiple myeloma.. Oncopeptides AB.

Bortezomib and high-dose melphalan conditioning regimen in frontline multiple myeloma: an IFM randomized phase 3 study.
    Blood, 2022, 05-05, Volume: 139, Issue:18

    High-dose melphalan (HDM) and transplantation are recommended for eligible patients with multiple myeloma. No other conditioning regimen has proven to be more effective and/or safer. We previously reported in a phase 2 study that bortezomib can safely and effectively be combined with HDM (Bor-HDM), with a 32% complete response (CR) rate after transplantation. These data supported a randomized phase 3 trial. Randomization was stratified according to risk and response to induction: 300 patients were enrolled, and 154 were allocated to the experimental arm (ie, arm A) with bortezomib (1 mg/m2 intravenously [IV]) on days -6, -3, +1, and +4 and melphalan (200 mg/m2 IV) on day -2. The control arm (ie, arm B) consisted of HDM alone (200 mg/m2 IV). There were no differences in stringent CR + CR rates at day 60 posttransplant (primary end point): 22.1% in arm A vs 20.5% in arm B (P = .844). There were also no differences in undetectable minimum residual disease rates: 41.3% vs 39.4% (P = .864). Median progression-free survival was 34.0 months for arm A vs 29.6 months for arm B (adjusted HR, 0.82; 95% CI, 0.61-1.13; P = .244). The estimated 3-year overall survival was 89.5% in both arms (hazard ratio, 1.28; 95% CI, 0.62-2.64; P = .374). Sixty-nine serious adverse events occurred in 18.7% of Bor-HDM-treated patients (vs 13.1% in HDM-treated patients). The proportion of grade 3/4 AEs was similar within the 2 groups (72.0% vs 73.1%), mainly (as expected) blood and gastrointestinal disorders; 4% of patients reported grade 3/4 or painful peripheral neuropathy in arm A (vs 1.5% in arm B). In this randomized phase 3 study, a conditioning regimen with Bor-HDM did not improve efficacy end points or outcomes compared with HDM alone. The original trial was registered at www.clinicaltrials.gov as #NCT02197221.

Long-Term Follow-Up of Multiple Myeloma Patients Treated with Tandem Autologous Transplantation Following Melphalan and Upon Recovery, Total Marrow Irradiation.
    Transplantation and cellular therapy, 2022, Volume: 28, Issue:7

    Total body irradiation in combination with melphalan for multiple myeloma (MM) has been shown to be prohibitively toxic. To ameliorate toxicity, total marrow irradiation (TMI) has been administered as the sole ablative modality during the second cycle of tandem autologous stem cell transplantation (TASCT) for MM patients on a phase I-II trial. Patients with MM in response or with stable disease and ≤18 months from diagnosis received melphalan 200 mg/m

Supporting the gastrointestinal microenvironment during high-dose chemotherapy and stem cell transplantation by inhibiting IL-1 signaling with anakinra.
    Scientific reports, 2022, 05-11, Volume: 12, Issue:1

    High-dose chemotherapy causes intestinal inflammation and subsequent breakdown of the mucosal barrier, permitting translocation of enteric pathogens, clinically manifesting as fever. Antibiotics are mainstay for controlling these complications, however, they are increasingly recognized for their detrimental effects, including antimicrobial resistance and dysbiosis. Here, we show that mucosal barrier injury induced by the mucotoxic chemotherapeutic agent, high-dose melphalan (HDM), is characterized by hyper-active IL-1b/CXCL1/neutrophil signaling. Inhibition of this pathway with IL-1RA, anakinra, minimized the duration and intensity of mucosal barrier injury and accompanying clinical symptoms, including diarrhea, weight loss and fever in rats. 16S analysis of fecal microbiome demonstrated a more stable composition in rats receiving anakinra, with reduced pathogen expansion. In parallel, we report through Phase IIA investigation that anakinra is safe in stem cell transplant patients with multiple myeloma after HDM. Ramping-up anakinra (100-300 mg administered intravenously for 15 days) did not cause any adverse events or dose limiting toxicities, nor did it change time to neutrophil recovery. Our results reinforce that strengthening the mucosal barrier may be an effective supportive care strategy to mitigate local and systemic clinical consequences of HDM. We are now conducting a Phase IIB multicenter, placebo-controlled, double-blinded trial to assess clinical efficacy of anakinra (AFFECT-2).Trial registration: ClinicalTrials.gov identifier: NCT03233776.

High-Dose Bendamustine, Etoposide, Cytarabine, and Melphalan (BeEAM) Conditioning Before Autologous Transplantation for Patients With Multiple Myeloma.
    Transplantation and cellular therapy, 2022, Volume: 28, Issue:8

    Single-agent high-dose melphalan (Mel) followed by autologous stem cell transplantation (ASCT) remains a standard of care in eligible patients with multiple myeloma (MM), and efforts to improve transplant outcomes by intensifying transplant conditioning have mostly failed. Bendamustine combines both alkylating and antimetabolite properties, can induce responses in MM resistant to other alkylators and represents a promising agent to combine with Mel prior to ASCT. We performed a phase II study to test the safety and efficacy of the high-dose chemotherapy combination of bendamustine, etoposide, cytarabine, and melphalan (BeEAM) in newly diagnosed MM patients up to 70 years of age. The primary study endpoint was the day 100 complete response rate. Sixty-five patients with a median (range) age of 59 (40-69) years underwent transplantation from 2015 to 2020. Other characteristics included Karnofsky performance status <80%, hematopoietic cell transplantation-comorbidity index ≥3, International Staging System III, and high-risk fluorescein in situ hybridization (FISH) in 35%, 46%, 26%, and 44%, respectively. ASCT after BeEAM was well tolerated, and there were no non-relapse deaths through 1 year after transplantation. Although at least 1 nonhematologic grade 3 toxicity was reported in 58 (89%) patients (including grade 3 febrile neutropenia in 48% and stomatitis/esophagitis in 28%), there were no grade ≥3 renal or hepatic toxicity and no grade ≥4 non-hematologic toxicity. The day 100 response rate was ≥CR1 and ≥ very good partial response (VGPR1) in 40% and 89%, respectively. With a median follow-up of 44 (13-70) months, the 3-year overall survival was 92%, 96%, and 90% for all patients and those with standard- and high-risk FISH, respectively. The corresponding values for 3-year progression-free survival was 57%, 72%, and 40%, respectively. When BeEAM-conditioned patients were compared to historical Mel-conditioned cohort, no significant differences were noted in relapse or survival outcomes in univariate or multivariable analysis. In summary, BeEAM was shown to be a safe and effective conditioning regimen before up-front autologous transplant for MM. Although the BeEAM regimen does not appear to offer a significant advantage over single-agent Mel, further studies combining bendamustine and melphalan in the front-line setting may be warranted.

Triplet Therapy, Transplantation, and Maintenance until Progression in Myeloma.
    The New England journal of medicine, 2022, 07-14, Volume: 387, Issue:2

    In patients with newly diagnosed multiple myeloma, the effect of adding autologous stem-cell transplantation (ASCT) to triplet therapy (lenalidomide, bortezomib, and dexamethasone [RVD]), followed by lenalidomide maintenance therapy until disease progression, is unknown.. In this phase 3 trial, adults (18 to 65 years of age) with symptomatic myeloma received one cycle of RVD. We randomly assigned these patients, in a 1:1 ratio, to receive two additional RVD cycles plus stem-cell mobilization, followed by either five additional RVD cycles (the RVD-alone group) or high-dose melphalan plus ASCT followed by two additional RVD cycles (the transplantation group). Both groups received lenalidomide until disease progression, unacceptable side effects, or both. The primary end point was progression-free survival.. Among 357 patients in the RVD-alone group and 365 in the transplantation group, at a median follow-up of 76.0 months, 328 events of disease progression or death occurred; the risk was 53% higher in the RVD-alone group than in the transplantation group (hazard ratio, 1.53; 95% confidence interval [CI], 1.23 to 1.91; P<0.001); median progression-free survival was 46.2 months and 67.5 months. The percentage of patients with a partial response or better was 95.0% in the RVD-alone group and 97.5% in the transplantation group (P = 0.55); 42.0% and 46.8%, respectively, had a complete response or better (P = 0.99). Treatment-related adverse events of grade 3 or higher occurred in 78.2% and 94.2%, respectively; 5-year survival was 79.2% and 80.7% (hazard ratio for death, 1.10; 95% CI, 0.73 to 1.65).. Among adults with multiple myeloma, RVD plus ASCT was associated with longer progression-free survival than RVD alone. No overall survival benefit was observed.

Matching-Adjusted Indirect Treatment Comparison to Assess the Comparative Efficacy of Ciltacabtagene Autoleucel in CARTITUDE-1 Versus Belantamab Mafodotin in DREAMM-2, Selinexor-Dexamethasone in STORM Part 2, and Melphalan Flufenamide-Dexamethasone in HOR
    Clinical lymphoma, myeloma & leukemia, 2022, Volume: 22, Issue:9

    This study estimated the comparative efficacy of ciltacabtagene autoleucel (cilta-cel; CARTITUDE-1), a chimeric antigen receptor (CAR)-T-cell therapy, versus 3 non-CAR-T therapies (belantamab mafodotin [DREAMM-2], selinexor plus dexamethasone [STORM Part 2], and melphalan flufenamide plus dexamethasone [HORIZON]), each with distinct mechanisms of action, for the treatment of patients with relapsed or refractory multiple myeloma (RRMM) who were triple-class exposed to an immunomodulatory drug, proteasome inhibitor, and an anti-CD38 monoclonal antibody.. Pairwise matching-adjusted indirect treatment comparisons (MAICs) were conducted using patient-level data for cilta-cel from CARTITUDE-1 and summary level data for each comparator (2.5 mg/kg cohort in DREAMM-2, modified intention-to-treat population in STORM Part 2, and triple-class refractory patients in HORIZON). Treated patients from CARTITUDE-1 who satisfied the eligibility of the comparator trial were included. MAICs adjusted for imbalances in important prognostic factors between CARTITUDE-1 and the comparator populations. Comparative efficacy of cilta-cel versus each therapy was estimated for overall response rate, complete response or better rate, progression-free survival, and overall survival.. After adjustment, patients treated with cilta-cel demonstrated at least a 3.1-fold and at least a 10.3-fold increase in the likelihood of achieving an overall response or complete response or better, respectively, at least a 74% reduction in the risk of disease progression or death, and at least a 47% reduction in the risk of death. These results were statistically significant.. Cilta-cel showed improved efficacy over each comparator for all outcomes, demonstrating its potential as an efficacious treatment for patients with triple-class exposed RRMM.

HLA genotyping in Japanese patients with multiple myeloma receiving bortezomib: An exploratory biomarker study of JCOG1105 (JCOG1105A1).
    Cancer science, 2021, Volume: 112, Issue:12

    Bortezomib (Btz) shows robust efficacy in patients with multiple myeloma (MM); however, some patients experience suboptimal responses and show specific toxicities. Therefore, we attempted to identify specific HLA alleles associated with Btz-related toxicities and response to treatment. Eighty-two transplant-ineligible patients with newly diagnosed MM enrolled in a phase II study (JCOG1105) comparing two less intensive melphalan, prednisolone, plus Btz (MPB) regimens were subjected to HLA typing. The frequency of each allele was compared between the groups, categorized based on toxicity grades and responses to MPB therapy. Among 82 patients, the numbers of patients with severe peripheral neuropathy (PN; grade 2 or higher), skin disorders (SD; grade 2 or higher), and pneumonitis were 16 (19.5%), 15 (18.3%), and 6 (7.3%), respectively. Complete response was achieved in 10 (12.2%) patients. Although no significant HLA allele was identified by multiple comparisons, several candidates were identified. HLA-B*40:06 was more prevalent in patients with severe PN than in those with less severe PN (odds ratio [OR] = 6.76). HLA-B*40:06 and HLA-DRB1*12:01 were more prevalent in patients with SD than in those with less severe SD (OR = 7.47 and OR = 5.55, respectively). HLA-DRB1*08:02 clustered in the group of patients with pneumonitis (OR = 11.34). Complete response was achieved in patients carrying HLA-DQB1*03:02, HLA-DQB1*05:01, and HLA-DRB1*01:01 class II alleles. HLA genotyping could help predict Btz-induced toxicity and treatment efficacy in patients with MM, although this needs further validation.

Early relapse after high-dose melphalan autologous stem cell transplant predicts inferior survival and is associated with high disease burden and genetically high-risk disease in multiple myeloma.
    British journal of haematology, 2021, Volume: 193, Issue:3

    Predicting patient outcome in multiple myeloma remains challenging despite the availability of standard prognostic biomarkers. We investigated outcome for patients relapsing early from intensive therapy on NCRI Myeloma XI. Relapse within 12 months of autologous stem cell transplant was associated with markedly worse median progression-free survival 2 (PFS2) of 18 months and overall survival (OS) of 26 months, compared to median PFS2 of 85 months and OS of 91 months for later relapsing patients despite equal access to and use of subsequent therapies, highlighting the urgent need for improved outcome prediction and early intervention strategies for myeloma patients.

    Journal of clinical oncology : official journal of the American Society of Clinical Oncology, 2021, 03-01, Volume: 39, Issue:7

    Melphalan flufenamide (melflufen) is a first-in-class peptide-drug conjugate that targets aminopeptidases and rapidly and selectively releases alkylating agents into tumor cells. The phase II HORIZON trial evaluated the efficacy of melflufen plus dexamethasone in relapsed and refractory multiple myeloma (RRMM), a population with an important unmet medical need.. Patients with RRMM refractory to pomalidomide and/or an anti-CD38 monoclonal antibody received melflufen 40 mg intravenously on day 1 of each 28-day cycle plus once weekly oral dexamethasone at a dose of 40 mg (20 mg in patients older than 75 years). The primary end point was overall response rate (partial response or better) assessed by the investigator and confirmed by independent review. Secondary end points included duration of response, progression-free survival, overall survival, and safety. The primary analysis is complete with long-term follow-up ongoing.. Of 157 patients (median age 65 years; median five prior lines of therapy) enrolled and treated, 119 patients (76%) had triple-class-refractory disease, 55 (35%) had extramedullary disease, and 92 (59%) were refractory to previous alkylator therapy. The overall response rate was 29% in the all-treated population, with 26% in the triple-class-refractory population. In the all-treated population, median duration of response was 5.5 months, median progression-free survival was 4.2 months, and median overall survival was 11.6 months at a median follow-up of 14 months. Grade ≥ 3 treatment-emergent adverse events occurred in 96% of patients, most commonly neutropenia (79%), thrombocytopenia (76%), and anemia (43%). Pneumonia (10%) was the most common grade 3/4 nonhematologic event. Thrombocytopenia and bleeding (both grade 3/4 but fully reversible) occurred concomitantly in four patients. GI events, reported in 97 patients (62%), were predominantly grade 1/2 (93%); none were grade 4.. Melflufen plus dexamethasone showed clinically meaningful efficacy and a manageable safety profile in patients with heavily pretreated RRMM, including those with triple-class-refractory and extramedullary disease.

Tandem autologous hematopoietic cell transplantation with sequential use of total marrow irradiation and high-dose melphalan in multiple myeloma.
    Bone marrow transplantation, 2021, Volume: 56, Issue:6

    The goal of this phase II trial was to evaluate safety and efficacy of a tandem autologous hematopoietic cell transplantation (auto-HCT) using sequentially total marrow irradiation (TMI) at the dose of 12 Gy (4 Gy on days -3, -2, and -1) and melphalan 200 mg/m

Melflufen plus dexamethasone in relapsed/refractory multiple myeloma: long-term survival follow-up from the Phase II study O-12-M1.
    British journal of haematology, 2021, Volume: 193, Issue:6

    An updated survival analysis was conducted for the Phase II study O-12-M1 of melphalan flufenamide (melflufen) plus dexamethasone in patients with relapsed/refractory multiple myeloma (RRMM) with two or more prior lines of therapy (including bortezomib and lenalidomide). Partial response or better was seen in 31%. After a 46-month median overall survival (OS) follow-up, melflufen plus dexamethasone had a median OS of 20·7 months (75th percentile OS, 47·5 months). The median time-to-next treatment for melflufen plus dexamethasone was 7·9 months. In summary, melflufen plus dexamethasone resulted in sustained long-term clinical benefit in patients with RRMM.

Single response assessment of transplant-ineligible multiple myeloma: a supplementary analysis of JCOG1105 (JCOG1105S1).
    Japanese journal of clinical oncology, 2021, Jul-01, Volume: 51, Issue:7

    The International Myeloma Working Group response criteria require two consecutive assessments of paraprotein levels. We conducted an exploratory analysis to evaluate whether a single response assessment could be a substitute for the International Myeloma Working Group criteria using data from JCOG1105, a randomized phase II study on melphalan, prednisolone and bortezomib.. Of 91 patients with transplant-ineligible newly diagnosed multiple myeloma, 79 patients were included. We calculated the kappa coefficient to evaluate the degree of agreement between the International Myeloma Working Group criteria and the single response assessment.. Based on the International Myeloma Working Group criteria, 11 (13.9%), 20 (25.3%), 36 (45.6%) and 12 (15.2%) patients had stringent complete response/complete response, very good partial response, partial response and stable disease, respectively. Based on the single response assessment, 17 (21.5%), 19 (24.1%), 35 (44.3%) and 8 (10.1%) patients had stringent complete response/complete response, very good partial response, partial response and stable disease, respectively. The kappa coefficient was 0.76 (95% confidence interval, 0.65-0.88), demonstrating good agreement. The single response assessment was not inferior to the International Myeloma Working Group criteria in the median progression-free survival (3.8 and 2.9 years) in stringent complete response/complete response patients, suggesting that the single response assessment was not an overestimation.. The single response assessment could be a substitute for the current International Myeloma Working Group criteria for transplant-ineligible newly diagnosed multiple myeloma.

Health-related quality of life in patients with newly diagnosed multiple myeloma ineligible for stem cell transplantation: results from the randomized phase III ALCYONE trial.
    BMC cancer, 2021, Jun-02, Volume: 21, Issue:1

    In the phase III ALCYONE trial, daratumumab plus bortezomib/melphalan/prednisone (D-VMP) significantly improved overall response rate and progression-free status compared with VMP alone in transplant-ineligible patients with newly diagnosed multiple myeloma (NDMM). Here, we present patient-reported outcomes (PROs) from ALCYONE.. The European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire Core 30-item (EORTC QLQ-C30) and EuroQol 5-dimensional descriptive system (EQ-5D-5L) questionnaire were administered at baseline, every 3 months (year 1) and every 6 months (until progression). Treatment effects were assessed using a repeated-measures, mixed-effects model.. Compliance with PRO assessments was comparable at baseline (> 90%) and throughout study (> 76%) for both treatment groups. Improvements from baseline were observed in both groups for EORTC QLQ-C30 Global Health Status (GHS), most functional scales, symptom scales and EQ-5D-5L visual analog scale (VAS). Between-group differences were significant for GHS (p = 0.0240) and VAS (p = 0.0160) at month 3. Improvements in pain were clinically meaningful in both groups at all assessment time points. Cognitive function declined in both groups, but the magnitude of the decline was not clinically meaningful.. Patients with transplant-ineligible NDMM demonstrated early and continuous improvements in health-related quality of life, including improvements in functioning and symptoms, following treatment with D-VMP or VMP..

A simplified frailty scale predicts outcomes in transplant-ineligible patients with newly diagnosed multiple myeloma treated in the FIRST (MM-020) trial.
    Leukemia, 2020, Volume: 34, Issue:1

    Patients with multiple myeloma are generally older and vary in fitness levels, which may influence the clinical benefit of treatment. Patients from the large, phase 3 FIRST trial in newly diagnosed multiple myeloma (NDMM) were retrospectively investigated to determine outcomes based on frailty using scores for age, Charlson Comorbidity Index (CCI), and Eastern Cooperative Oncology Group performance status (ECOG PS), instead of the EQ-5D quality-of-life questionnaire, as previously reported. ECOG PS (n = 1618) was investigated in frailty groups: frail (49%) and nonfrail (51%). Frail patients experienced worse progression-free and overall survival vs nonfrail patients. Prognostic assessment was improved when combining frailty and International Staging System stage (I/II vs III). Frail patients had a higher risk of developing grade 3/4 treatment-emergent adverse events. Treatment effects observed in the FIRST trial were confirmed per frailty group and per frailty and ISS group. The use of this ECOG PS-containing frailty scale as a predictive measure of clinical outcomes in patients with transplant-ineligible NDMM is supported by data from the FIRST trial. This score, based on age, CCI, and ECOG PS, can be easily replicated and may help design future myeloma studies in frail or nonfrail elderly patients.

Health-related quality of life in transplant ineligible newly diagnosed multiple myeloma patients treated with either thalidomide or lenalidomide-based regimen until progression: a prospective, open-label, multicenter, randomized, phase 3 study.
    Haematologica, 2020, Volume: 105, Issue:6

    Data on the impact of long term treatment with immunomodulatory drugs (IMiD) on health-related quality of life (HRQoL) is limited. The HOVON-87/NMSG18 study was a randomized, phase 3 study in newly diagnosed transplant ineligible patients with multiple myeloma, comparing melphalan-prednisolone in combination with thalidomide or lenalidomide, followed by maintenance therapy until progression (MPT-T or MPR-R). The EORTC QLQ-C30 and MY20 questionnaires were completed at baseline, after three and nine induction cycles and six and 12 months of maintenance therapy. Linear mixed models and minimal important differences were used for evaluation. 596 patients participated in HRQoL reporting. Patients reported clinically relevant improvement in global quality of life (QoL), future perspective and role and emotional functioning, and less fatigue and pain in both arms. The latter being of large effect size. In general, improvement occurred after 6-12 months of maintenance only and was independent of the World Health Organisation performance at baseline. Patients treated with MPR-R reported clinically relevant worsening of diarrhea, and patients treated with MPT-T reported a higher incidence of neuropathy. Patients who remained on lenalidomide maintenance therapy for at least three months reported clinically meaningful improvement in global QoL and role functioning at six months, remaining stable thereafter. There were no clinically meaningful deteriorations, but patients on thalidomide reported clinically relevant worsening in neuropathy. In general, HRQoL improves both during induction and maintenance therapy with immunomodulatory drugs. The side effect profile of treatment did not negatively affect global QoL, but it was, however, clinically relevant for the patients. (

Lenalidomide-based induction and maintenance in elderly newly diagnosed multiple myeloma patients: updated results of the EMN01 randomized trial.
    Haematologica, 2020, Volume: 105, Issue:7

    n the EMN01 trial, the addition of an alkylator (melphalan or cyclophosphamide) to lenalidomide-steroid induction therapy was prospectively evaluated in transplant-ineligible patients with multiple myeloma. After induction, patients were randomly assigned to maintenance treatment with lenalidomide alone or with prednisone continuously. The analysis presented here (median follow-up of 71 months) is focused on maintenance treatment and on subgroup analyses defined according to the International Myeloma Working Group Frailty Score. Of the 654 evaluable patients, 217 were in the lenalidomide-dexamethasone arm, 217 in the melphalan-prednisone-lenalidomide arm and 220 in the cyclophosphamide-prednisone-lenalidomide arm. With regards to the Frailty Score, 284 (43%) patients were fit, 205 (31%) were intermediate-fit and 165 (25%) were frail. After induction, 402 patients were eligible for maintenance therapy (lenalidomide arm, n=204; lenalidomide-prednisone arm, n=198). After a median duration of maintenance of 22.0 months, progression-free survival from the start of maintenance was 22.2 months with lenalidomide-prednisone

Frailty impairs the feasibility of induction therapy but not of maintenance therapy in elderly myeloma patients: final results of the German Maintenance Study (GERMAIN).
    Journal of cancer research and clinical oncology, 2020, Volume: 146, Issue:3

    The German Maintenance Study (GERMAIN) was designed to evaluate the impact of lenalidomide maintenance after induction therapy with bortezomib, melphalan and prednisolone (VMP) in transplant-ineligible newly diagnosed multiple myeloma (MM) patients.. Due to poor accrual and high dropout rate, only 85 patients (planned 286) entered the trial and 40 (planned 200) were randomized to lenalidomide maintenance (n = 19) vs. observation (n = 21).. The primary endpoint, improved progression-free survival, was not met (p = 0.3572). After a median follow-up of 12.9 months, median progression-free survival in the lenalidomide arm was 14.4 months and 11.4 months with placebo. The hazard ratio 0.621 (95% confidence interval: [0.224, 1.725]) was about the same as expected (0.625). However, with only 40 patients randomized, the actual power to detect a difference was 11%. Of patients receiving at least one dose of induction, 54% were frail according to a modified International Myeloma Working Group frailty score. Discontinuations were high during induction (47%), and affected mainly frail patients (54%). Despite a higher rate of adverse events in the lenalidomide arm (p = 0.0061), only 2 patients discontinued lenalidomide due to toxicity.. A frailty assessment with appropriate dose modification for induction therapy should be mandatory for all elderly non-transplant-eligible myeloma patients.

A comparative effectiveness study of lipegfilgrastim in multiple myeloma patients after high dose melphalan and autologous stem cell transplant.
    Annals of hematology, 2020, Volume: 99, Issue:2

    G-CSF administration after high-dose chemotherapy and autologous stem cell transplantation (ASCT) has been shown to expedite neutrophil recovery. Several studies comparing filgrastim and pegfilgrastim in the post-ASCT setting concluded that the two are at least equally effective. Lipegfilgrastim (LIP) is a new long-acting, once-per-cycle G-CSF. This multicentric, prospective study aimed to describe the use of LIP in multiple myeloma patients receiving high-dose melphalan and autologous stem cell transplantation (ASCT) and compare LIP with historic controls of patients who received short-acting agent (filgrastim [FIL]). Overall, 125 patients with a median age of 60 years received G-CSF after ASCT (80 patients LIP on day 1 post-ASCT and 45 patients FIL on day 5 post-ASCT). The median duration of grade 4 neutropenia (absolute neutrophil count [ANC] < 0.5 × 10 [9]/L) was 5 days in both LIP and FIL groups, whereas the median number of days to reach ANC ≥ 0.5 × 10 [9]/L was 10% lower in the LIP than in the FIL group (10 vs 11 days), respectively. Male sex was significantly associated with a faster ANC ≥ 0.5 × 10 [9] L response (p = 0.015). The incidence of FN was significantly lower in the LIP than in the FIL group (29% vs 49%, respectively, p = 0.024). The days to discharge after ASCT infusion were greater in patients with FN (p < 0.001). The study indicates that LIP had a shorter time to ANC recovery and is more effective than FIL for the prevention of FN in the ASCT setting.

Pomalidomide, cyclophosphamide, and dexamethasone for elderly patients with relapsed and refractory multiple myeloma: A study of the Korean Multiple Myeloma Working Party (KMMWP-164 study).
    American journal of hematology, 2020, Volume: 95, Issue:4

    Patients with transplant-ineligible relapsed and refractory multiple myeloma (RRMM) have a short life expectancy, especially when they have failed both the proteasome inhibitor and immunomodulator therapies. This study aimed to assess the efficacy and safety of pomalidomide, cyclophosphamide, and dexamethasone (PCd) in elderly patients with RRMM. This phase 2 clinical trial recruited 55 elderly patients with RRMM. The patients underwent a 28-day treatment cycle: pomalidomide (4 mg/day on days 1-21, administered orally) and cyclophosphamide (400 mg/day on days 1, 8, and 15; administered orally) plus dexamethasone. The median (range) age of the patients was 73.3 (64-86) years, and 8 (14.5%) patients who were ≥ 80 years old. Eight (14.5%) and 31 (56.4%) patients exhibited stage III (revised international staging system) and frail status (simplified frailty scale), respectively. The overall response rate (ORR) and clinical benefit rate (CBR) of PCd therapy were 58.2% and 72.7%, respectively. The median PFS and median overall survival (OS) were 6.90 months (95% CI, 4.7-9.0) and 18.48 months (95% CI, 9.4-27.6), respectively. The incidence rate of grade ≥ 3 non-hematological toxicities was 70.8%. In particular, the incidence rate of primary infection was 45.4%, including 21.8% for pneumonia, 9.0% for sepsis, and 14.6% for febrile neutropenia. In conclusion, PCd is an effective regimen for elderly patients with RRMM who had failed both bortezomib and lenalidomide treatments, but in whom the treatment-associated infection is the main cause of morbidity and mortality.

Response-adapted lenalidomide maintenance in newly diagnosed myeloma: results from the phase III GMMG-MM5 trial.
    Leukemia, 2020, Volume: 34, Issue:7

    The MM5 trial aimed at demonstrating a progression-free survival (PFS) difference in continued vs. response-adapted (in case of complete response, CR) lenalidomide (LEN) maintenance therapy (MT) in newly diagnosed, transplant-eligible multiple myeloma (MM). Patients were equally randomized to receive induction therapy with PAd (bortezomib/doxorubicin/dexamethasone) or VCD (bortezomib/cyclophosphamide/dexamethasone), high-dose melphalan and autologous blood stem cell transplantation, and LEN consolidation, followed by either LEN MT for a fixed duration of 2 years (LEN-2Y) or until achievement of CR (LEN-CR, intention-to-treat population n = 502): arms A1:PAd + LEN-2Y (n = 125), B1:PAd + LEN-CR (n = 126), A2:VCD + LEN-2Y (n = 126), B2:VCD + LEN-CR (n = 125). In the LEN-CR group (B1 + B2), n = 88/17.5% patients did not start or discontinued LEN MT due to CR. There was no PFS (p = 0.60, primary endpoint) nor overall survival (OS) (p = 0.15) difference between the four study arms. On pooled LEN MT strategies, OS (hazard ratio, hazard ratio [HR] = 1.42, p = 0.03) but not PFS (HR = 1.15, p = 0.20) was shorter in LEN-CR (B1 + B2) vs. LEN-2Y (A1 + A2) groups. PFS was shortened on landmark analyses from the start of LEN MT in patients being in CR in the LEN-CR group (LEN-CR vs. LEN-2Y, HR = 1.84, p = 0.02). OS from first progression was shortened in the LEN-CR vs. LEN-2Y group (HR = 1.60, p = 0.01). LEN MT should be applied beyond CR for at least 2 years.

OCEAN: a randomized Phase III study of melflufen + dexamethasone to treat relapsed refractory multiple myeloma.
    Future oncology (London, England), 2020, Volume: 16, Issue:11

    Melflufen is a novel peptide-drug conjugate that rapidly delivers a cytotoxic payload into tumor cells. It has emerged as a potential new multiple myeloma treatment, particularly for late-stage forms of the disease. Here we describe the rationale and design of OCEAN (NCT03151811), a randomized, head-to-head, superiority, open-label, global, Phase III study evaluating the efficacy and safety of melflufen + dexamethasone versus pomalidomide + dexamethasone. Eligible patients with relapsed refractory multiple myeloma have received 2-4 previous treatments and are refractory to both lenalidomide and their last treatment. Patients are excluded if they have previously received pomalidomide. The primary endpoint is progression-free survival, and key secondary endpoints include overall response rate, duration of response and overall survival.

Impact of the Conditioning Regimen Dose Intensity Before Autologous Stem Cell Transplantation on the Pulmonary Function Test Abnormalities in Patients With Lymphoma and Multiple Myeloma: Single Center Experience.
    Clinical lymphoma, myeloma & leukemia, 2020, Volume: 20, Issue:6

    Most studies addressing the impact of hematopoietic stem cell transplantation (SCT) on pulmonary function test (PFT), and the various factors affecting that impact have been performed on the allogenic type. Few have addressed PFT changes in autologous SCT. This study describes PFT changes seen in autologous SCT recipients and addresses the various factors impacting these changes.. We reviewed the medical records of 223 consecutive adult autologous SCT recipients. We collected pre-transplant and post-transplant data, as well as PFT data and long-term mortality.. A total of 123 patients with lymphoma receiving the BEAM (carmustine, etoposide, aracytin, and melphalan) conditioning regimen had a significant 5% drop in mean forced vital capacity and total lung capacity but no significant change in forced expiratory volume in one second/forced vital capacity ratio nor in diffusion lung capacity of carbon monoxide adjusted to volume. Fifteen percent of the patients with lymphoma had a clinically significant drop of 15% in their lung volume parameters. The patients with multiple myeloma receiving the melphalan conditioning regimen had no significant change in any of the PFT parameters. Smoking, baseline PFT parameters, and radiation did not affect lung function or mortality.. Autologous SCT impact on lung function depends on the disease and conditioning regimen. It leads to a drop in lung volumes but no obstruction or decrease in diffusion in patients with lymphoma receiving the BEAM regimen. Autologous SCT did not affect lung functions in patients with multiple myeloma, and these patients may not need screening PFTs.

Melflufen plus dexamethasone in relapsed and refractory multiple myeloma (O-12-M1): a multicentre, international, open-label, phase 1-2 study.
    The Lancet. Haematology, 2020, Volume: 7, Issue:5

    Multiple myeloma is an incurable haematological malignancy, representing over 10% of haematological cancers in the USA. We did a phase 1-2 study of melflufen and dexamethasone in patients with relapsed and refractory multiple myeloma to determine the maximum tolerated dose of melflufen and to investigate its safety and efficacy.. We did a multicentre, international, dose-confirmation and dose-expansion, open-label, phase 1-2 study in seven centres in the USA and Europe. Eligible patients were aged 18 years or older, had relapsed and refractory multiple myeloma, had received two or more previous lines of therapy (including lenalidomide and bortezomib), were refractory to their last line of therapy, and had an Eastern Cooperative Oncology Group performance status of 2 or less. In phase 1, patients received an intravenous infusion of melflufen at 15 mg, 25 mg, 40 mg, or 55 mg for 30 min on day 1 in 21-day cycles plus oral dexamethasone 40 mg weekly and did not receive melflufen as a single agent. Melflufen was also tested in a single-agent cohort late in phase 2 in a small number of patients at the maximum tolerated dose identified in phase 1. In phase 2, patients were enrolled at the maximum tolerated dose in the melflufen plus dexamethasone in the combination cohort.. The phase 1 primary objective was to determine the maximum tolerated dose. The phase 2 primary objective was to evaluate overall response rate and clinical benefit rate. This primary analysis was done per protocol, in the all-treated and efficacy-evaluable population (defined as patients who received at least two doses of melflufen and who had a response assessment after baseline). The single-agent melflufen cohort was closed on October 6, 2016, as per the recommendation by the data safety monitoring committee on the basis of interim data suggesting greater activity in the melflufen plus dexamethasone cohort. The study is completed but survival follow-up is ongoing. This study is registered with ClinicalTrials.gov, NCT01897714.. Patients were enrolled between July 4, 2013, and Dec 31, 2016: 23 patients in phase 1 and 58 in phase 2, including six patients from phase 1 treated at the maximum tolerated dose of melflufen 40 mg plus weekly dexamethasone. In phase 2, 45 patients were given a combination of melflufen plus dexamethasone and 13 patients were given single-agent melflufen. In phase 1, the established maximum tolerated dose was 40 mg of melflufen in combination with dexamethasone. No dose-limiting toxicities were observed in the first three dose cohorts (15 mg, 25 mg, and 40 mg). The highest dose cohort tested (55 mg) exceeded the maximum tolerated dose because four of six patients experienced grade 4 neutropenia with grade 4 thrombocytopenia also occurring in three of these patients; therefore, the planned highest dose of 70 mg was not tested. In phase 2, patients treated with combination therapy achieved an overall response rate of 31% (14 of 45 patients; 95% CI 18-47) and clinical benefit rate of 49% (22 of 45; 34-64) in the all-treated population, and 41% (14 of 34; 25-59) and 65% (22 of 34; 47-80) in the efficacy-evaluable population. In the phase 2 single-agent cohort, the overall response rate was 8% (one of 13 patients; 0·2-36·0) and the clinical benefit rate was 23% (three of 13; 5-54). Among the 45 patients given melflufen plus dexamethasone during phase 2, the most common grade 3-4 adverse events were clinically manageable thrombocytopenia (28 [62%] patients) and neutropenia (26 [58%]), and non-haematological toxicity was infrequent. 24 serious adverse events were reported in 17 (38%) of 45 patients, most commonly pneumonia (five [11%]). The most common grade 3-4 adverse events that occurred in the phase 2 single-agent cohort of 13 patients were neutropenia (nine [69%]) and thrombocytopenia (eight [62%]). Nine patients experienced serious adverse events in the single-agent cohort, most commonly thrombocytopenia (two [15%]). There were three deaths from adverse events within 30 days of treatment that were possibly related to treatment: one in the 25 mg cohort in phase 1 (due to bacteraemia) and two in the phase 2 combination cohort (one due to neutropenic sepsis and one due to Escherichia coli sepsis), each in the setting of progressive disease.. These data show that melflufen is active in patients with relapsed and refractory multiple myeloma and tolerable in most patients.

Continuous lenalidomide treatment after bortezomib-melphalan-prednisolone therapy for newly diagnosed multiple myeloma.
    Annals of hematology, 2020, Volume: 99, Issue:5

    These are the results of phase II study of bortezomib-melphalan-prednisolone (VMP) induction therapy followed by lenalidomide-dexamethasone (Rd) consolidation and lenalidomide maintenance in transplant-ineligible patients with newly diagnosed multiple myeloma (NDMM). The primary end point was progression-free survival (PFS). Secondary end points included overall survival (OS), overall response rates (ORRs), and safety. Eighty-three eligible patients were enrolled between October 2012 and August 2014. The median PFS was 28.0 months (95% CI 19.6-36.7) and the median OS was 55.3 months (95% CI 51.6-NA). Among the patients who received lenalidomide maintenance therapy, median PFS was significantly improved in patients who had achieved a very good partial response (VGPR) or better (41.8 vs 20.7 months, p = 0.0070). As the best response, the rates of partial response or better were 85.5% comprising stringent complete response (sCR, 21.7%), complete response (CR, 10.8%), VGPR (18.1%), and partial response (PR, 34.9%). The most frequently observed grade 3 or higher adverse events during the VMP therapy were anemia (28.9%), neutropenia (15.6%), thrombocytopenia (6.0%), and peripheral neuropathy (2.4%). The most frequently observed grade 3 or higher adverse events during the Rd therapy were anemia (3.5%), neutropenia (1.8%), and skin rush (5.3%). The most frequently observed grade 3 or higher adverse events during lenalidomide maintenance therapy were anemia (7.4%) and neutropenia (24.1%). Thus, VMP induction therapy followed by Rd consolidation and lenalidomide maintenance is considered a well-tolerated and effective regimen in transplant-ineligible NDMM. This trial is registered with UMIN-CTR with the identification number UMIN000009042.

Comparative Efficacy of Bortezomib, Melphalan, and Prednisone (VMP) With or Without Daratumumab Versus VMP Alone in the Treatment of Newly Diagnosed Multiple Myeloma: Propensity Score Matching of ALCYONE and VISTA Phase III Studies.
    Clinical lymphoma, myeloma & leukemia, 2020, Volume: 20, Issue:7

    Bortezomib, melphalan, and prednisone (VMP) is the standard of care for transplant-ineligible newly diagnosed multiple myeloma. The phase III VISTA trial established the bortezomib dosing schedule for VMP. To mitigate bortezomib-associated toxicity, the phase III ALCYONE study of daratumumab plus VMP (D-VMP) versus VMP used modified bortezomib dosing. D-VMP demonstrated improved progression-free survival and overall response rate. Propensity score matching enables indirect comparisons by controlling for differences in baseline covariates.. The efficacy and safety of both arms of ALCYONE were compared with VISTA VMP using propensity score matching. ALCYONE D-VMP and VMP patients were matched on selected baseline characteristics to VISTA VMP patients, reducing or eliminating systematic differences between treatment groups.. After matching, median progression-free survival and overall response rate were comparable for ALCYONE VMP and VISTA VMP, and were significantly improved with ALCYONE D-VMP versus VISTA VMP. Rates of grade 3/4 peripheral sensory neuropathy were significantly lower for both arms of ALCYONE versus VISTA VMP, with or without matching.. This propensity score matching analysis demonstrates significant improvements in efficacy with ALCYONE D-VMP versus VISTA VMP and a significantly lower incidence of peripheral sensory neuropathy in both arms of ALCYONE versus VISTA VMP, although safety improvements may be due to different bortezomib administration routes (ALCYONE, subcutaneous; VISTA, intravenous).

Thrombosis in patients with myeloma treated in the Myeloma IX and Myeloma XI phase 3 randomized controlled trials.
    Blood, 2020, 08-27, Volume: 136, Issue:9

    Newly diagnosed multiple myeloma (NDMM) patients treated with immunomodulatory drugs are at high risk of venous thromboembolism (VTE), but data are lacking from large prospective cohorts. We present thrombosis outcome data from Myeloma IX (n = 1936) and Myeloma XI (n = 4358) phase 3 randomized controlled trials for NDMM that treated transplant-eligible and transplant-ineligible patients before and after publication of thrombosis prevention guidelines. In Myeloma IX, transplant-eligible patients randomly assigned to cyclophosphamide, vincristine, doxorubicin, and dexamethasone (CVAD) induction had higher risk of VTE compared with patients treated with cyclophosphamide, thalidomide, and dexamethasone (CTD) (22.5% [n = 121 of 538] vs 16.1% [n = 89 of 554]; adjusted hazard ratio [aHR],1.46; 95% confidence interval [95% CI], 1.11-1.93). For transplant-ineligible patients, those randomly assigned to attenuated CTD (CTDa) induction had a higher risk of VTE compared with those treated with melphalan and prednisolone (MP) (16.0% [n = 68 of 425] vs 4.1% [n = 17 of 419]; aHR, 4.25; 95% CI, 2.50-7.20). In Myeloma XI, there was no difference in risk of VTE (12.2% [n = 124 of 1014] vs 13.2% [n = 133 of 1008]; aHR, 0.92; 95% CI, 0.72-1.18) or arterial thrombosis (1.2% [n = 12 of 1014] vs 1.5% [n = 15 of 1008]; aHR, 0.80; 95% CI, 0.37-1.70) between transplant-eligible pathways for patients treated with cyclophosphamide, lenalidomide, and dexamethasone (CRD) or CTD. For transplant-ineligible patients, there was no difference in VTEs between attenuated CRD (CRDa) and CTDa (10.4% [n = 95 of 916] vs 10.7% [n = 97 of 910]; aHR, 0.97; 95% CI, 0.73-1.29). However, arterial risk was higher with CRDa than with CTDa (3.1% [n = 28 of 916] vs 1.6% [n = 15 of 910]; aHR, 1.91; 95% CI, 1.02-3.57). Thrombotic events occurred almost entirely within 6 months of treatment initiation. Thrombosis was not associated with inferior progression-free survival (PFS) or overall survival (OS), apart from inferior OS for patients with arterial events (aHR, 1.53; 95% CI, 1.12-2.08) in Myeloma XI. The Myeloma XI trial protocol incorporated International Myeloma Working Group (IMWG) thrombosis prevention recommendations and compared with Myeloma IX, more patients received thromboprophylaxis (80.5% vs 22.3%) with lower rates of VTE for identical regimens (CTD, 13.2% vs 16.1%; CTDa, 10.7% vs 16.0%). However, thrombosis remained frequent in spite of IMWG-guided thromboprophylaxis, suggesting that new appro

Low-dose lenalidomide and dexamethasone therapy after melphalan-prednisolone induction in elderly patients with newly diagnosed multiple myeloma.
    Annals of hematology, 2020, Volume: 99, Issue:10

    Lenalidomide (Len) and dexamethasone (dex) therapy is a standard therapy in patients with multiple myeloma. Elderly or unfit patients may reduce Len or dex doses to prevent toxicities that lead to treatment discontinuation. However, there have been few studies evaluating the efficacy and safety of lower doses of Len and dex. We conducted a phase II study of 1.5-year low-dose Len and dex therapy following melphalan and prednisolone (MP), the number of which cycles was determined by a response within 9 cycles. The Len dose was 10 mg daily and the dex dose was 20 mg weekly, which were continued for 1.5 years. Twenty-one patients were enrolled. The median number of cycles of MP was 3 (range, 2-9). The overall response rate was 81% and a very good partial response or better was achieved in 33.3% of patients. The median follow-up time for survivors was 70.5 months (range, 42-83 months), the median progression-free survival (PFS) was 27 months (95% CI, 21-33 months), and the median overall survival was not reached. Grade 3 or 4 adverse events were observed in 28.6% of patients. In conclusion, the low-dose Len and dex therapy safely achieved comparable efficacies to the standard-dose regimen in elderly patients with newly diagnosed multiple myeloma. UMIN000007889.

Propylene Glycol-Free Melphalan versus PG-Melphalan as Conditioning for Autologous Hematopoietic Cell Transplantation for Myeloma.
    Biology of blood and marrow transplantation : journal of the American Society for Blood and Marrow Transplantation, 2020, Volume: 26, Issue:12

    High-dose melphalan (Mel) conditioning before autologous hematopoietic cell transplantation (autoHCT) is standard of care for patients with transplantation-eligible multiple myeloma. The traditional lyophilized Mel formulation has inadequate solubility and stability after reconstitution, leading to the use of propylene glycol (PG) as a solubilizing agent. A newer PG-free Mel preparation (Evomela) uses beta cyclodextrin captisol as a solubilizing agent and was approved by the United States Food and Drug Administration as a conditioning agent based on a single-phase IIb study showing bioequivalence. We compared the outcomes of consecutive patients with myeloma undergoing autoHCT using the 2 formulations of Mel for conditioning as our center switched from using the older formulation (PG-Mel) to the newer one (PGF-Mel). Of 294 autoHCT recipients, 162 received PG-Mel conditioning and 132 received PGF-Mel conditioning. The PGF-Mel group was older and had a lower average Karnofsky Performance Status score. PGF-Mel was associated with faster neutrophil recovery (median, 12 days versus 13 days; P < .001), fewer grade 3-4 infections within 30 days of autoHCT (1.5% versus 8.0%; P = .048), and a lower 30-day rehospitalization rate (6.8% versus 17.9%; P = .04), as confirmed by propensity-weighted analysis. No significant between-group differences were detected in mucositis, organ toxicity, myeloma response, or 100-day mortality.

Continuous lenalidomide and low-dose dexamethasone in patients with transplant-ineligible newly diagnosed MM: FIRST trial subanalysis of Canadian/US patients.
    Cancer medicine, 2020, Volume: 9, Issue:23

    The phase 3 FIRST trial demonstrated significant improvement in progression-free survival (PFS) and overall survival (OS) with an immune-stimulatory agent, lenalidomide, in combination with low-dose dexamethasone until disease progression (Rd continuous) vs melphalan +prednisone + thalidomide (MPT) in transplant-ineligible patients with newly diagnosed multiple myeloma (NDMM). Rd continuous similarly extended PFS vs fixed-duration Rd for 18 cycles (Rd18). Outcomes in the Canadian/US subgroup (104 patients per arm) are reported in this analysis. Rd continuous demonstrated a significant improvement in PFS vs MPT (median, 29.3 vs 20.2 months; HR, 0.69 [95% CI, 0.49-0.97]; p = 0.03326) and an improvement vs Rd18 (median, 21.9 months). Median OS was 56.9 vs 46.8 months with Rd continuous vs MPT (p = 0.15346) and 59.5 months with Rd18. The overall response rate was higher with Rd continuous and Rd18 (78.8% and 79.8%) vs MPT (65.4%). In the 49.0%, 52.9%, and 29.8% of patients with at least very good partial response in the Rd continuous, Rd18, and MPT arms, respectively, the median PFS was 56.0, 30.9, and 40.2 months, respectively. The most common grade 3/4 treatment-emergent adverse events were neutropenia (28.4%, 30.1%, and 52.0%), anemia (23.5%, 21.4%, and 23.5%), and infections (37.3%, 30.1%, and 24.5%) with Rd continuous, Rd18, and MPT, respectively. These results were consistent with those in the intent-to-treat population, confirming the benefit of Rd continuous vs MPT in the Canadian/US subgroup and supporting the role of Rd continuous as a standard of care for transplant-ineligible patients with NDMM.

Daratumumab Plus Bortezomib, Melphalan, and Prednisone Versus Standard of Care in Latin America for Transplant-Ineligible Newly Diagnosed Multiple Myeloma: Propensity Score Matching Analysis.
    Advances in therapy, 2020, Volume: 37, Issue:12

    The phase 3 ALCYONE study demonstrated significantly longer progression-free and overall survival (PFS/OS) and higher overall response rates (ORR) with daratumumab plus bortezomib, melphalan, and prednisone (D-VMP) versus VMP alone in transplant-ineligible patients with newly diagnosed multiple myeloma (NDMM). In Latin America, bortezomib- or thalidomide-based regimens remain standard of care (SoC) for this population. No head-to-head trials have compared D-VMP with SoC regimens used in Latin America.. Propensity score matching (PSM) was used to control for baseline differences between patient populations and compare outcomes for D-VMP versus SoC regimens used in Latin America. Data for the D-VMP cohort were from the D-VMP arm of the ALCYONE trial (n = 350). Data for the SoC cohort were from the retrospective, observational Hemato-Oncology Latin America (HOLA) study, which included patients with NDMM who did not receive a transplant (n = 729). Propensity scores were estimated using logistic regression. Exact, optimal, and nearest-neighbor PSM were applied to pick the best-performing method. Doubly robust estimation was the base case, since some baseline imbalances persisted.. All 350 patients from the D-VMP arm of ALCYONE were included in OS/PFS analyses and 338 in ORR analysis; 478 and 324 patients, respectively, from HOLA were included in these analyses. Naïve comparison revealed important differences in baseline characteristics (age, chronic kidney disease, hypercalcemia, and International Staging System [ISS] stage). After nearest-neighbor matching, baseline characteristics, except ISS stage, were well balanced; comparisons favored D-VMP over SoC for OS (hazard ratio = 0.41; 95% confidence interval [CI] 0.25-0.66; P = 0.002) and PFS (hazard ratio = 0.48; 95% CI 0.35-0.67; P < 0.001). After exact matching, imbalances remained in age and ISS stage; comparisons favored D-VMP over SoC for ORR (odds ratio = 5.44; 95% CI 2.65-11.82; P < 0.001).. In transplant-ineligible patients with NDMM, D-VMP showed superior effectiveness versus bortezomib- and thalidomide-based regimens, supporting adoption of daratumumab-containing regimens in Latin America.

First-line therapy with either bortezomib-melphalan-prednisone or lenalidomide-dexamethasone followed by lenalidomide for transplant-ineligible multiple myeloma patients: a pooled analysis of two randomized trials.
    Haematologica, 2020, Volume: 105, Issue:4

    Bortezomib-melphalan-prednisone (VMP) and continuous lenalidomide-dexamethasone (Rd) represent the standard treatment of transplant-ineligible patients with newly diagnosed multiple myeloma (MM). To date, no randomized trial has compared VMP to Rd, and there is no evidence of the optimal treatment for newly diagnosed MM, particularly in patients with high-risk cytogenetics [del(17p), t(4;14) or t(14;16)]. We pooled together data from patients with newly diagnosed MM treated with VMP or Rd induction followed by lenalidomide maintenance 10 mg (Rd-R) enrolled in the GIMEMA-MM-03-05 and EMN01 trials, to evaluate the efficacy of these treatments in different subgroups of patients, focusing on those with standard- and high-risk cytogenetics. Overall, 474 patients were analyzed (VMP: 257 patients; Rd-R: 217 patients). No differences in progression-free survival (hazard ratio=0.96) and overall survival (hazard ratio=1.08) were observed between standard-risk patients treated with VMP or Rd-R, whereas among the high-risk patients, the probabilities of progression (hazard ratio=0.54) and death (hazard ratio=0.73) were lower in the patients treated with VMP than in those treated with Rd-R. In particular, standard-risk patients >75 years benefited less from VMP than from Rd-R (hazard ratio for progression-free survival=0.96; hazard ratio for overall survival=1.81). In this non-randomized analysis, VMP and Rd-R were equally effective in younger (≤75 years), standard-risk patients, while older ones (>75 years) benefited more from Rd-R. In high-risk patients, VMP improved progression-free survival and overall survival irrespective of age. The source trials are registered at ClinicalTrials.gov (NCT01063179 and NCT01093196).

A phase II study of lenalidomide consolidation and maintenance therapy after autologous PBSCT in patients with multiple myeloma.
    International journal of hematology, 2019, Volume: 109, Issue:1

    The efficacy and safety of lenalidomide (LEN) consolidation therapy and subsequent LEN maintenance therapy after high-dose therapy with autologous peripheral blood stem cell transplantation (auto-PBSCT) were evaluated in patients with newly diagnosed symptomatic multiple myeloma (MM). Forty-one patients were enrolled and received high-dose dexamethasone (DEX) therapy as an initial induction. The patients who did not respond to the DEX therapy were further treated with four cycles of bortezomib plus DEX (BD) induction therapy. For patients who responded to BD, PBSC harvesting was scheduled following high-dose cyclophosphamide and filgrastim administration. After PBSC harvesting, high-dose chemotherapy of melphalan with auto-PBSCT was performed. One hundred days after auto-PBSCT, patients received consolidation therapy consisting two cycles of LEN plus low-dose DEX (Ld) and LEN maintenance therapy. Only one death occurred during mobilization therapy, but the protocol developed in this study was considered generally safe to provide. Overall response rates after consolidation and maintenance therapies were 73.7% and 81.6%, respectively. Two-year progression-free survival and overall survival were 76.3% and 92.1%, respectively. These observations suggest that LEN consolidation and maintenance therapy are effective and safe, and provide favorable response rates in patients with MM.

    Patients with symptomatic MM within 12 months from starting therapy and without progression who were age 70 years or younger were randomly assigned to AHCT/AHCT + len (n = 247), AHCT + RVD + len (n = 254), or AHCT + len (n = 257). The primary end point was 38-month PFS.. The study population had a median age of 56 years (range, 20 to 70 years); 24% of patients had high-risk MM, 73% had a triple-drug regimen as initial therapy, and 18% were in complete response at enrollment. The 38-month PFS rate was 58.5% (95% CI, 51.7% to 64.6%) for AHCT/AHCT + len, 57.8% (95% CI, 51.4% to 63.7%) for AHCT + RVD + len, and 53.9% (95% CI, 47.4% to 60%) for AHCT + len. For AHCT/AHCT + len, AHCT + RVD + len, and AHCT + len, the OS rates were 81.8% (95% CI, 76.2% to 86.2%), 85.4% (95% CI, 80.4% to 89.3%), and 83.7% (95% CI, 78.4% to 87.8%), respectively, and the complete response rates at 1 year were 50.5% (n = 192), 58.4% (n = 209), and 47.1% (n = 208), respectively. Toxicity profiles and development of second primary malignancies were similar across treatment arms.. Second AHCT or RVD consolidation as post-AHCT interventions for the up-front treatment of transplantation-eligible patients with MM did not improve PFS or OS. Single AHCT and len should remain as the standard approach for this population.

Cryotherapy as prophylaxis against oral mucositis after high-dose melphalan and autologous stem cell transplantation for myeloma: a randomised, open-label, phase 3, non-inferiority trial.
    Bone marrow transplantation, 2019, Volume: 54, Issue:9

    The conditioning therapy used in connection with haematopoietic stem cell transplantation (HSCT) can induce painful oral mucositis, which has negative impacts on patient quality of life and survival, as well as on health-care costs. While cooling of the oral mucosa (cryotherapy) is regarded as standard prophylaxis against oral mucositis, the long duration of the treatment affects compliance owing to side effects. In this prospective, randomised trial, 94 patients (62 males/32 females; median age 59 years, range 34-69) with a diagnosis of myeloma who were undergoing autologous HSCT were randomised 1:1 to receive cryotherapy for 7 h (N = 46) or 2 h (N = 48). Oral mucositis was evaluated prospectively. No significant difference was observed with respect to the proportion of patients who showed grades 3 and 4 toxicity according to the WHO scale (2.1 and 4.3% for 2 and 7 h, respectively; 95% CI -0.09 to 0.049; p = 0.98) as between the groups. Two hours of cryotherapy was as effective as 7 h in terms of protecting against severe oral mucositis in connection with autologous HSCT for myeloma. This trial is registered with ClinicalTrials.gov (NCT03704597).

Apixaban for the prevention of thromboembolism in immunomodulatory-treated myeloma patients: Myelaxat, a phase 2 pilot study.
    American journal of hematology, 2019, Volume: 94, Issue:6

    The risk of venous thromboembolism (VTE) is higher in myeloma patients receiving immunomodulatory compounds. A VTE prophylaxis using low-molecular-weight heparin or aspirin is therefore proposed. Apixaban is an oral direct anti-Xa. Several studies have shown the efficacy and safety of apixaban in VTE prophylaxis compared to enoxaparin. The objective of this prospective phase 2 pilot study was to assess the risk of VTE and bleeding in patients with myeloma treated with immunomodulatory compounds lenalidomide (len) or thalidomide (thal), using apixaban in a preventive scheme. Myeloma patients requiring Melphalan-Prednisone-Thalidomide in the first line, or Lenalidomide-Dexamethasone in the relapse setting received apixaban, 2.5 mg x 2/day for 6 months. Venous (pulmonary embolism-PE, or symptomatic proximal or distal deep vein thrombosis-DVT, or all proximal asymptomatic events detected by systematic proximal bilateral compression ultrasound) or arterial thrombotic events, and bleeding events (ISTH 2005) were registered. One hundred and four patients were enrolled (mean age 69.8 ± 7.8 years), 11 in first line and 93 in relapse. Two venous thrombotic events were observed, for example, an asymptomatic proximal DVT and a symptomatic distal DVT, in the context of apixaban stopped 14 days before, due to lenalidomide-induced thrombocytopenia. No PE or arterial cardiovascular events were reported. Only one major and 11 CRNM hemorrhages were reported. These data must now be confirmed on a randomized large study.

Bortezomib-based strategy with autologous stem cell transplantation for newly diagnosed multiple myeloma: a phase II study by the Japan Study Group for Cell Therapy and Transplantation (JSCT-MM12).
    International journal of clinical oncology, 2019, Volume: 24, Issue:8

    The Japan Study Group for Cell Therapy and Transplantation (JSCT) organized a phase II study to evaluate the efficacy and safety of a treatment protocol (JSCT-MM12) for multiple myeloma (MM) patients who were previously untreated and transplantation-eligible. Since bortezomib-based therapy is known to be effective for MM, the protocol is intensified more than the previous protocol (JSCT-MM10) and comprised the subsequent treatments: bortezomib + cyclophosphamide + dexamethasone (VCD) induction; bortezomib + high-dose-melphalan (B-HDM) conditioning with autologous stem cell transplantation (ASCT); bortezomib + thalidomide + dexamethasone (VTD) consolidation; and lenalidomide (LEN) maintenance.. Sixty-four symptomatic patients aged between 20 and 65 years were enrolled for treatment and received three cycles of VCD, followed by cyclophosphamide administration for autologous stem cell harvest and B-HDM/ASCT, and subsequently two cycles of VTD, after that LEN for 1 year.. Complete response (CR)/stringent CR (sCR) rates for induction, ASCT, consolidation, and maintenance therapies were 20, 39, 52, and 56%, respectively. The grade 3/4 toxicities (≥ 10%) with VCD treatment included neutropenia (27%), anemia (19%), and thrombocytopenia (11%). There was no treatment-related mortality. After median follow-up of 41 months, estimated 3-year progression-free survival (PFS) and overall survival (OS) rates were 64% and 88%, respectively. The high-risk group revealed lower CR/sCR, PFS, and OS than the standard-risk group.. The study revealed that the treatment protocol consisting of VCD induction, B-HDM/ASCT followed by VTD consolidation, and LEN maintenance could produce highly beneficial responses and favorable tolerability in newly diagnosed MM. However, future study is required for improving treatment in the high-risk group.

Gastrointestinal Microbiome and Mycobiome Changes during Autologous Transplantation for Multiple Myeloma: Results of a Prospective Pilot Study.
    Biology of blood and marrow transplantation : journal of the American Society for Blood and Marrow Transplantation, 2019, Volume: 25, Issue:8

    Microbiome dysbiosis has been associated with adverse outcomes of hematopoietic cell transplantation (HCT). We hypothesized that exposure to high-dose melphalan and antimicrobials in patients undergoing autologous HCT for plasma cell disorders results in oral and gastrointestinal microbial dysbiosis, which in turn is associated with regimen-related toxicities. We conducted a prospective study describing the longitudinal changes in oral and gastrointestinal bacteriome and mycobiome in this patient population. Our findings show that microbiome composition present at baseline is associated with the incidence and severity of post-transplantation nausea, vomiting, and culture-negative neutropenic fever, as well as with the rate of neutrophil engraftment. We also have evidence of an association between the microbial communities at count nadir and the development of regimen-related gastrointestinal toxicities commonly observed after exposure to high-dose melphalan. Although bacteriome diversity largely recovers within 1 month after transplantation, we observed a continuous decrease in oral and gastrointestinal mycobiome diversity, suggesting that the mycobiome requires a longer time to recover compared with the bacteriome.

Rationale and design of the German-speaking myeloma multicenter group (GMMG) trial HD6: a randomized phase III trial on the effect of elotuzumab in VRD induction/consolidation and lenalidomide maintenance in patients with newly diagnosed myeloma.
    BMC cancer, 2019, May-28, Volume: 19, Issue:1

    GMMG-HD6 is a randomized, open, multicenter phase III trial. The planned recruitment number is 564 NDMM patients. All patients will receive 4 VRD cycles as induction and undergo peripheral blood stem cell mobilization and harvesting. Thereafter they will be treated with high dose melphalan therapy plus autologous stem cell transplantation followed by 2 cycles of VRD consolidation and lenalidomide maintenance. Patients in arm B1 + B2 will additionally receive elotuzumab in the induction phase, whereas patients in A2 + B2 will be treated with elotuzumab added to consolidation and maintenance. The primary endpoint of the trial is PFS. Secondary objectives and endpoints are OS, CR rates after induction therapy comparing the two arms VRD (A1 + A2) vs VRD + elotuzumab (B1 + B2), CR rates after consolidation treatment, best response to treatment during the study, time to progression (TTP), duration of response (DOR), toxicity and quality of life.. Since this is the publication of a study protocol of an ongoing study, no results can be presented.. This phase III trial is designed to evaluate whether the addition of elotuzumab to an intensified treatment concept with high dose melphalan chemotherapy plus autologous stem cell transplantation and induction, consolidation and maintenance treatment with bortezomib and lenalidomide is able to improve PFS compared to the same concept without elotuzumab..

Post-treatment improvement of NK cell numbers predicts better survival in myeloma patients treated with thalidomide-based regimens.
    International journal of hematology, 2019, Volume: 110, Issue:3

    Multiple myeloma (MM) is a disease characterized by antitumoral immune dysfunction. The objective of the present study was to determine lymphocyte subsets (B, T, NK, NKT, iNKT, dendritic cells, and regulatory T cells) in 68 newly diagnosed patients and 113 healthy donors. Lymphocyte subsets were studied in the same patients 6 months after treatment. Pre-treatment values of CD4+ T cells, NK cells, type 2 dendritic cells, and B cells in MM patients were lower than in healthy donors. Forty patients (59%) received MPT treatment and 28 (41%) thal-dex. Patients with no response to treatment, exhibited a decrease in CD4+ T cells and NK cells, as well as an increase in Treg cell numbers. Median DFS and OS was lower in patients not achieving response, in patients having low numbers of NK cells, and higher values of LDH. The number of CD4 T cells, NK, DC2, and B cells at diagnosis is lower in patients with MM. Non-responder patients had lower CD4 and NK, but higher Treg cell values. Patients in which response is not achieved, and those holding lower values of NK cells and higher levels of LDH, have poor DFS and OS.

Report of phase I and II trials of melphalan, prednisolone, and thalidomide triplet combination therapy versus melphalan and prednisolone doublet combination therapy in Japanese patients with newly diagnosed multiple myeloma ineligible for autologous stem
    International journal of hematology, 2019, Volume: 110, Issue:4

    We conducted a phase I study to determine the recommended dose of thalidomide combined with melphalan plus prednisolone (MPT) and a phase II study evaluating the efficacy and safety of this MPT regimen in transplant-ineligible Japanese patients with untreated multiple myeloma. The recommended dose was determined to be 100 mg/day in the phase I study. In the phase II, randomized, double-blind, parallel-group study, patients were allocated to either MPT (n = 52) or MP (n = 51), with 21 and 29 patients completing the study, respectively. Overall response rate, the primary endpoint, was significantly higher in the MPT [40.4% (21/52 patients), 95% confidence interval (CI) 27.0-54.9%] than in the MP [19.6% (10/51 patients), 95% CI 9.8-33.1%] group (P = 0.022). Time to response was also significantly shorter in the MPT group. Incidences of hematological toxicities were similar in the two groups, suggesting that addition of thalidomide did not increase hematological toxicity. Although incidences of some non-hematological toxicities tended to be higher in the MPT group, the low incidence of ≥ Grade 3 toxicities suggests that MPT therapy was well tolerated. These results support the safety and efficacy of MPT therapy in untreated Japanese multiple myeloma patients.

Population Pharmacokinetics and Optimal Sampling Strategy for Model-Based Precision Dosing of Melphalan in Patients Undergoing Hematopoietic Stem Cell Transplantation.
    Clinical pharmacokinetics, 2018, Volume: 57, Issue:5

    High-dose melphalan is an important component of conditioning regimens for patients undergoing hematopoietic stem cell transplantation. The current dosing strategy based on body surface area results in a high incidence of oral mucositis and gastrointestinal and liver toxicity. Pharmacokinetically guided dosing will individualize exposure and help minimize overexposure-related toxicity.. The purpose of this study was to develop a population pharmacokinetic model and optimal sampling strategy.. A population pharmacokinetic model was developed with NONMEM using 98 observations collected from 15 adult patients given the standard dose of 140 or 200 mg/m. A two-compartment model best described the data. The final model included body weight and creatinine clearance as predictors of clearance. The determinant-optimal sampling strategies (and windows) were identified at 0.08 (0.08-0.19), 0.61 (0.33-0.90), 2.0 (1.3-2.7), and 4.0 (3.6-4.0) h post-infusion. An excellent correlation was observed between area under the curve estimates obtained with the full and the proposed four-sample strategy (R. The developed pharmacokinetic model-based sparse sampling strategy promises to achieve the target area under the curve as part of precision dosing.

Daratumumab plus Bortezomib, Melphalan, and Prednisone for Untreated Myeloma.
    The New England journal of medicine, 2018, 02-08, Volume: 378, Issue:6

    The combination of bortezomib, melphalan, and prednisone is a standard treatment for patients with newly diagnosed multiple myeloma who are ineligible for autologous stem-cell transplantation. Daratumumab has shown efficacy in combination with standard-of-care regimens in patients with relapsed or refractory multiple myeloma.. In this phase 3 trial, we randomly assigned 706 patients with newly diagnosed multiple myeloma who were ineligible for stem-cell transplantation to receive nine cycles of bortezomib, melphalan, and prednisone either alone (control group) or with daratumumab (daratumumab group) until disease progression. The primary end point was progression-free survival.. At a median follow-up of 16.5 months in a prespecified interim analysis, the 18-month progression-free survival rate was 71.6% (95% confidence interval [CI], 65.5 to 76.8) in the daratumumab group and 50.2% (95% CI, 43.2 to 56.7) in the control group (hazard ratio for disease progression or death, 0.50; 95% CI, 0.38 to 0.65; P<0.001). The overall response rate was 90.9% in the daratumumab group, as compared with 73.9% in the control group (P<0.001), and the rate of complete response or better (including stringent complete response) was 42.6%, versus 24.4% (P<0.001). In the daratumumab group, 22.3% of the patients were negative for minimal residual disease (at a threshold of 1 tumor cell per 10. Among patients with newly diagnosed multiple myeloma who were ineligible for stem-cell transplantation, daratumumab combined with bortezomib, melphalan, and prednisone resulted in a lower risk of disease progression or death than the same regimen without daratumumab. The daratumumab-containing regimen was associated with more grade 3 or 4 infections. (Funded by Janssen Research and Development; ALCYONE ClinicalTrials.gov number, NCT02195479 .).

Anti-CD19 CAR T cells with high-dose melphalan and autologous stem cell transplantation for refractory multiple myeloma.
    JCI insight, 2018, 04-19, Volume: 3, Issue:8

    Multiple myeloma is usually fatal due to serial relapses that become progressively refractory to therapy. CD19 is typically absent on the dominant multiple myeloma cell population but may be present on minor subsets with unique myeloma-propagating properties. To target myeloma-propagating cells, we clinically evaluated autologous T cells transduced with a chimeric antigen receptor (CAR) against CD19 (CTL019).. Subjects received CTL019 following salvage high-dose melphalan and autologous stem cell transplantation (ASCT). All subjects had relapsed/refractory multiple myeloma and had previously undergone ASCT with less than 1 year progression-free survival (PFS).. ASCT + CTL019 was safe and feasible, with most toxicity attributable to ASCT and no severe cytokine release syndrome. Two of 10 subjects exhibited significantly longer PFS after ASCT + CTL019 compared with prior ASCT (479 vs. 181 days; 249 vs. 127 days). Correlates of favorable clinical outcome included peak CTL019 frequency in bone marrow and emergence of humoral and cellular immune responses against the stem-cell antigen Sox2. Ex vivo treatment of primary myeloma samples with a combination of CTL019 and CAR T cells against the plasma cell antigen BCMA reliably inhibited myeloma colony formation in vitro, whereas treatment with either CAR alone inhibited colony formation inconsistently.. CTL019 may improve duration of response to standard multiple myeloma therapies by targeting and precipitating secondary immune responses against myeloma-propagating cells..

Lower glomerular filtration rate predicts increased hepatic and mucosal toxicity in myeloma patients treated with high-dose melphalan.
    International journal of hematology, 2018, Volume: 108, Issue:4

    High-dose melphalan followed by autologous hematopoietic stem cell transplantation (ASCT) is a standard treatment for younger myeloma patients. However, the correlation between its toxicity and renal impairment is not clear. We analyzed this relationship, focusing on estimated glomerular filtration rate (eGFR) as an index of renal function. We evaluated 78 multiple myeloma patients who underwent ASCT following high-dose melphalan at our center. Patients were divided into a higher eGFR group (eGFR ≥ 60) and a lower eGFR group (eGFR < 60). Multivariate analyses revealed that lower eGFR was independently associated with alkaline phosphatase elevation (OR 10.2, P = 0.038), mucositis (OR 10.5, P = 0.032), grade 2-4 co-elevation of both aspartate aminotransferase and alanine aminotransferase (OR 21.3, P = 0.016), delay of reticulocyte engraftment (HR 0.524, P = 0.034), and delay of platelet engraftment (HR 0.535, P = 0.0016). However, lower eGFR was not correlated with overall survival or time-to-next treatment. In summary, renal dysfunction secondary to administration of high-dose melphalan was associated with increased hepatic and mucosal toxicity and delay of hematological recovery, but did not affect survival outcomes.

Benefit of continuous treatment for responders with newly diagnosed multiple myeloma in the randomized FIRST trial.
    Leukemia, 2017, Volume: 31, Issue:11

    The phase 3, randomized Frontline Investigation of Revlimid and Dexamethasone Versus Standard Thalidomide (FIRST) trial investigating lenalidomide plus low-dose dexamethasone until disease progression (Rd continuous) vs melphalan, prednisone and thalidomide for 12 cycles (MPT) and Rd for 18 cycles (Rd18) in transplant-ineligible patients with newly diagnosed multiple myeloma (NDMM) showed that Rd continuous prolonged progression-free survival and overall survival compared with MPT. A subanalysis of the FIRST trial was conducted to determine the benefits of Rd continuous in patients with NDMM based on depth of response. Patients randomized 1:1:1 to Rd continuous, Rd18 or MPT were divided into subgroups based on best response: complete response (CR; n=290), ⩾very good partial response (VGPR; n=679), ⩾partial response (PR; n=1 225) or ⩽stable disease (n=299). Over 13% of patients receiving Rd continuous who achieved ⩾VGPR as best response did so beyond 18 months of treatment. Rd continuous reduced the risk of progression or death by 67%, 51% and 35% vs MPT in patients with CR, ⩾VGPR and ⩾PR, respectively. Similarly, Rd continuous reduced the risk of progression or death by 61%, 54% and 38% vs Rd18 in patients with CR, ⩾VGPR and ⩾PR, respectively. In patients with CR, ⩾VGPR or ⩾PR, 4-year survival rates in the Rd continuous arm (81.1%, 73.1% or 64.6%, respectively) were higher vs MPT (70.8%, 59.8% or 57.2%, respectively) and similar vs Rd18 (76.5%, 67.7% and 62.5%, respectively). Rd continuous improved efficacy outcomes in all responding patients, including those with CR, compared with fixed duration treatment.

Bortezomib pharmacokinetics in tumor response and peripheral neuropathy in multiple myeloma patients receiving bortezomib-containing therapy.
    Anti-cancer drugs, 2017, Volume: 28, Issue:6

    The usefulness of pharmacokinetics of bortezomib for multiple myeloma (MM) with respect to the maximum response to bortezomib and bortezomib-induced peripheral neuropathy (BIPN) development was studied. Maximum response to subcutaneous bortezomib therapy and BIPN occurrence for the first 12 weeks of treatment in 35 MM patients treated by bortezomib-dexamethasone (VD) and bortezomib-melphalan-prednisone (VMP) were evaluated. On day 1 of cycle 1, seven whole-blood samples were collected for 3 h after dosing completion to obtain the maximum plasma concentration and area under the time-concentration curve during 3 h postdose (AUC0-3) in each patient. A total of 35 patients with complete data were analyzed and the overall response rate was 91.4%. Complete response (CR) was observed in 42.9% patients. The maximum plasma concentration (Cmax) was significant for the CR rate in two different models [full model: odds ratio (OR)=1.092; P=0.038, final model: OR=1.081; P=0.038]. In addition, Cmax was associated with a progression-free survival advantage. Overall, 48.6% of patients developed BIPN including peripheral sensory neuropathy and neuralgia. The VMP-treated patients had a higher risk compared with the VD-treated patients (OR=21.662; P=0.029). Cmax had a tendency to affect the occurrence of BIPN (≥grade 2) (OR=1.064; P=0.092). In real-world clinical practice using bortezomib for MM patients, Cmax among pharmacokinetic factors significantly affected the achievement of CR. The VMP-treated patients showed vulnerability to BIPN, suggesting the necessity for more careful monitoring.

Lenalidomide and low-dose dexamethasone (Rd) versus bortezomib, melphalan, prednisone (VMP) in elderly newly diagnosed multiple myeloma patients: A comparison of two prospective trials.
    American journal of hematology, 2017, Volume: 92, Issue:3

    There are currently no direct head-to-head clinical trials evaluating bortezomib-melphalan-prednisone (VMP) versus lenalidomide and low-dose dexamethasone (Rd). VMP (257 cases) and Rd (222 cases) arms of two randomized phase III trials were employed to assess the treatment influence on outcome in untreated elderly MM patients. Progression free survival (PFS) and overall survival (OS) were the primary and secondary end-points, respectively, and were investigated according to treatments administered over a 60-months follow-up period. While VMP significantly reduced the disease progression rate between enrolment and 12 months of follow-up, no difference between the two schedules was found between 12 and 32 months. After 32 months, Rd-treated patients had a lower incidence of disease progression. A statistically significant higher OS rate was seen in the VMP arm, which was maintained after data adjustment for potential confounders. Both approaches showed acceptable toxicity profiles. The profound tumor reduction by VMP over Rd justifies the initial higher PFS rate in favor of the bortezomib schedule, while the Rd regimen overcomes this evident initial drawback in reducing the tumor burden by long-term drug administration, gaining a subsequent improved disease control. VMP is associated with a significant reduced risk of death. This study may help physicians make a more informed therapy choice.

Continuous treatment with lenalidomide and low-dose dexamethasone in transplant-ineligible patients with newly diagnosed multiple myeloma in Asia: subanalysis of the FIRST trial.
    British journal of haematology, 2017, Volume: 176, Issue:5

    The phase 3 FIRST (Frontline Investigation of REVLIMID + Dexamethasone Versus Standard Thalidomide) trial demonstrated that lenalidomide plus low-dose dexamethasone (Rd) until disease progression (Rd continuous) is an effective treatment option for transplant-ineligible patients with newly diagnosed multiple myeloma (NDMM). Given genetic differences between Asian and Western populations, this subanalysis of the FIRST trial examined the safety and efficacy of Rd (given continuously or for 18 cycles [Rd18]) and MPT (melphalan, prednisone, thalidomide) in 114 Asian patients from Mainland China, South Korea and Taiwan. Efficacy and safety with Rd continuous in Asian patients were consistent with those in the overall study population. The overall response rates were 77·8% for Rd continuous, 57·5% for MPT and 65·8% for Rd18. The risk of progression or death was reduced by 39% with Rd continuous versus MPT and by 35% with Rd continuous versus Rd18. Rd continuous improved the 3-year survival rate compared with MPT (70·2% vs. 56·4%) and Rd18 (58·1%). Common grade 3/4 adverse events in the Rd continuous and MPT arms were neutropenia (25·0% vs. 43·6%), infection (19·4% vs. 28·2%) and anaemia (19·4% vs. 15·4%), respectively. Thromboembolic event rates were low, and no second primary malignancies were observed. Rd continuous is safe and effective in transplant-ineligible Asian patients with NDMM.

Associations of High-Dose Melphalan Pharmacokinetics and Outcomes in the Setting of a Randomized Cryotherapy Trial.
    Clinical pharmacology and therapeutics, 2017, Volume: 102, Issue:3

    High-dose melphalan followed by autologous stem cell transplantation remains the standard of care for eligible patients with multiple myeloma, but disease response and toxicity, including severe mucositis, varies among patients. Our randomized trial investigated duration of cryotherapy (2 and 6 h) for reduction of mucositis prevalence and severity and explored factors associated with variability in pharmacokinetics and outcomes from melphalan therapy. The results demonstrate that 2-h is at least as effective as 6-h cryotherapy in decreasing severe mucositis. From a population pharmacokinetic model, we identified that fat-free mass, hematocrit, and creatinine clearance were significant covariates, as reported previously. Furthermore, we observed the rs4240803 SLC7A5 polymorphism was significantly associated with pharmacokinetic variability, and pharmacokinetics was associated with both mucositis and neutropenia. However, melphalan exposure was not associated with progression-free or overall survival in our dataset. These findings contribute to ongoing efforts to personalize melphalan dosing in transplant patients.

A Phase I Trial of High-Dose Lenalidomide and Melphalan as Conditioning for Autologous Stem Cell Transplantation in Relapsed or Refractory Multiple Myeloma.
    Biology of blood and marrow transplantation : journal of the American Society for Blood and Marrow Transplantation, 2017, Volume: 23, Issue:6

    Autologous stem cell transplantation (ASCT) conditioned with high-dose chemotherapy has long been established as the standard of care for eligible patients with newly diagnosed multiple myeloma. Despite recent therapeutic advances, high-dose melphalan (HDM) remains the chemotherapy regimen of choice in this setting. Lenalidomide (LEN) in combination with low-dose dexamethasone is recognized as a standard of care for patients with relapsed or refractory multiple myeloma (RRMM), and there is growing support for the administration of LEN as maintenance therapy post-ASCT. In view of the above, the present phase I clinical trial was designed to evaluate the safety and tolerability of high-dose LEN (HDLEN) in patients with RRMM, and to determine the maximum tolerated dose of HDLEN when added to HDM before ASCT. Despite administering HDLEN at doses of up to 350 mg/day, the maximum tolerated dose could not be determined, owing to an insufficient number of dose-limiting toxicities in the 21 patients enrolled in the trial. Conditioning with HDLEN plus HDM was associated with a favorable tolerability profile. Adverse events following ASCT were as expected with HDM. Median progression-free and overall survival were 10 months and 22 months, respectively, in this population of heavily pretreated patients. Our findings suggest that HDLEN in combination with HDM may offer significant potential as a conditioning regimen before ASCT in patients with RRMM. These preliminary findings are now being evaluated further in an ongoing phase II clinical trial.

A randomized study of melphalan 200 mg/m(2) vs 280 mg/m(2) as a preparative regimen for patients with multiple myeloma undergoing auto-SCT.
    Bone marrow transplantation, 2016, Volume: 51, Issue:1

    We aimed to examine whether doses of melphalan higher than 200 mg/m(2) improve response rates when used as conditioning before autologous transplant (ASCT) in multiple myeloma (MM) patients. Patients with MM, n=131, were randomized to 200 mg/m(2) (mel200) vs 280 mg/m(2) (mel280) using amifostine pretreatment. The primary end point was the proportion of patients achieving near complete response (⩾nCR). No treatment-related deaths occurred in this study. Responses following ASCT were for mel200 vs mel280, respectively, ⩾nCR 22 vs 39%, P=0.03, ⩾PR 57 vs 74%, P=0.04. The hazard of mortality was not statistically significantly different between groups (mel200 vs mel280; hazard ratio (HR)=1.15 (95% confidence interval (CI), 0.62-2.13, P=0.66)) nor was the rate of progression/mortality (HR=0.81 (0.52-1.27, P=0.36)). The estimated PFS at 1 and 3 years were 83 and 46%, respectively, for mel200 and 78 and 54%, respectively, for mel280. Amifostine and mel280 were well tolerated, with no grade 4 regimen-related toxicities and only one grade 3 mucositis (none with mel200) and three grade 3 gastrointestinal (GI) toxicities (two in mel200). Hospitalization rates were more frequent in the mel280 group (59 vs 43%, P=0.08). Mel280 resulted in a higher major response rate (CR+nCR) and should be evaluated in larger studies.

Sequential vs alternating administration of VMP and Rd in elderly patients with newly diagnosed MM.
    Blood, 2016, Jan-28, Volume: 127, Issue:4

    Bortezomib plus melphalan and prednisone (VMP) and lenalidomide plus low-dose dexamethasone (Rd) are 2 standards of care for elderly untreated multiple myeloma (MM) patients. We planned to use VMP and Rd for 18 cycles in a sequential or alternating scheme. Patients (233) with untreated MM, >65 years, were randomized to receive 9 cycles of VMP followed by 9 cycles of Rd (sequential scheme; n = 118) vs 1 cycle of VMP followed by 1 cycle of Rd, and so on, up to 18 cycles (alternating scheme; n = 115). VMP consisted of one 6-week cycle of bortezomib using a biweekly schedule, followed by eight 5-week cycles of once-weekly VMP. Rd included nine 4-week cycles of Rd. The primary end points were 18-month progression free survival (PFS) and safety profile of both schemes. The 18-month PFS was 74% and 80% in the sequential and alternating arms, respectively (P = .21). The sequential and alternating groups exhibited similar hematologic and nonhematologic toxicity. Both arms yielded similar complete response rate (42% and 40%), median PFS (32 months vs 34 months, P = .65), and 3-year overall survival (72% vs 74%, P = .63). The benefit of both schemes was remarkable in patients aged 65 to 75 years. In addition, achieving complete and immunophenotypic response was associated with better outcome. The present approach, based on VMP and Rd, is associated with high efficacy and acceptable toxicity profile with no differences between the sequential and alternating regimens. This trial was registered at www.clinicaltrials.gov as #NCT00443235.

Comparison of serum free light chain and urine electrophoresis for the detection of the light chain component of monoclonal immunoglobulins in light chain and intact immunoglobulin multiple myeloma.
    Haematologica, 2016, Volume: 101, Issue:3

    Response criteria for multiple myeloma are based upon changes in monoclonal protein levels quantified using serum and/or urine protein electrophoresis. The latter lacks sensitivity at low monoclonal protein levels and since 2001, the serum free light chain test has been available and its clinical utility proven, yet guidelines have not recommended it as a replacement for urine assessment. Herein we evaluated responses using serum free light chain measurements and serum and urine electrophoresis after 2 and 4 cycles of therapy and after stem cell transplantation in 25 light chain and 157 intact immunoglobulin myeloma patients enrolled in the IFM 2007-02 MM trial. All 25 light chain patients had measurable disease by serum free light chain and urine methods at presentation. By contrast 98 out of 157 intact immunoglobulin patients had measurable disease by serum free light chain compared to 55 out of 157 by urine electrophoresis. In all patients there was substantial agreement between predicate (serum/urine protein electrophoresis) and test (serum protein electrophoresis and serum free light chain) methods for response assessment (Weighted Kappa=0.83). Urine immunofixation became negative in 47% light chain and 43% intact immunoglobulin patients after 2 cycles of therapy. At this time the serum free light chain ratio normalised in only 11% and 27% patients, respectively. In summary we found good agreement between methods for response assessment, but the serum free light chain test provided greater sensitivity than urine electrophoresis for monitoring. To our knowledge this is the first report comparing both methods for response assignment based on the International Myeloma Working Group guidelines.

Impact of renal impairment on outcomes with lenalidomide and dexamethasone treatment in the FIRST trial, a randomized, open-label phase 3 trial in transplant-ineligible patients with multiple myeloma.
    Haematologica, 2016, Volume: 101, Issue:3

    Renal impairment is associated with poor prognosis in myeloma. This analysis of the pivotal phase 3 FIRST trial examined the impact of renally adapted dosing of lenalidomide and dexamethasone on outcomes of patients with different degrees of renal impairment. Transplant-ineligible patients not requiring dialysis were randomized 1:1:1 to receive continuous lenalidomide and dexamethasone until disease progression (n=535) or for 18 cycles (72 weeks; n=541), or melphalan, prednisone, and thalidomide for 12 cycles (72 weeks; n=547). Follow-up is ongoing. Patients were grouped by baseline creatinine clearance into no (≥ 80 mL/min [n=389]), mild (≥ 50 to < 80 mL/min [n=715]), moderate (≥ 30 to < 50 mL/min [n=372]), and severe impairment (< 30 mL/min [n=147]) subgroups. Continuous lenalidomide and dexamethasone therapy reduced the risk of progression or death in no, mild, and moderate renal impairment subgroups vs. melphalan, prednisone, and thalidomide therapy (HR = 0.67, 0.70, and 0.65, respectively). Overall survival benefits were observed with continuous lenalidomide and dexamethasone treatment vs. melphalan, prednisone, and thalidomide treatment in no or mild renal impairment subgroups. Renal function improved from baseline in 52.6% of lenalidomide and dexamethasone-treated patients. The safety profile of continuous lenalidomide and dexamethasone was consistent across renal subgroups, except for grade 3/4 anemia and rash, which increased with increasing severity of renal impairment. Continuous lenalidomide and dexamethasone treatment, with renally adapted lenalidomide dosing, was effective for most transplant-ineligible patients with myeloma and renal impairment.

Phenotypic and genomic analysis of multiple myeloma minimal residual disease tumor cells: a new model to understand chemoresistance.
    Blood, 2016, Apr-14, Volume: 127, Issue:15

    Persistence of chemoresistant minimal residual disease (MRD) plasma cells (PCs) is associated with inferior survival in multiple myeloma (MM). Thus, characterization of the minor MRD subclone may represent a unique model to understand chemoresistance, but to our knowledge, the phenotypic and genetic features of the MRD subclone have never been investigated. Here, we compared the antigenic profile of MRD vs diagnostic clonal PCs in 40 elderly MM patients enrolled in the GEM2010MAS65 study and showed that the MRD subclone is enriched in cells overexpressing integrins (CD11a/CD11c/CD29/CD49d/CD49e), chemokine receptors (CXCR4), and adhesion molecules (CD44/CD54). Genetic profiling of MRD vs diagnostic PCs was performed in 12 patients; 3 of them showed identical copy number alterations (CNAs), in another 3 cases, MRD clonal PCs displayed all genetic alterations detected at diagnosis plus additional CNAs that emerged at the MRD stage, whereas in the remaining 6 patients, there were CNAs present at diagnosis that were undetectable in MRD clonal PCs, but also a selected number of genetic alterations that became apparent only at the MRD stage. The MRD subclone showed significant downregulation of genes related to protein processing in endoplasmic reticulum, as well as novel deregulated genes such as ALCAM that is prognostically relevant in MM and may identify chemoresistant PCs in vitro. Altogether, our results suggest that therapy-induced clonal selection could be already present at the MRD stage, where chemoresistant PCs show a singular phenotypic signature that may result from the persistence of clones with different genetic and gene expression profiles. This trial was registered atwww.clinicaltrials.gov as #NCT01237249.

Fractionated stem cell infusions for patients with plasma cell myeloma undergoing autologous hematopoietic cell transplantation.
    Leukemia & lymphoma, 2016, Volume: 57, Issue:8

    We conducted a phase II trial investigating the impact of fractionated hematopoietic cell infusions on engraftment kinetics and symptom burden in patients with plasma cell myeloma (PCM) undergoing autologous hematopoietic cell transplant (AHCT). We hypothesized that multiple hematopoietic cell infusions would reduce duration of neutropenia and enhance immune recovery resulting in a better tolerated procedure. Twenty-six patients received high-dose melphalan followed by multiple cell infusions (Days 0, +2, +4, +6) and were compared to PCM patients (N = 77) who received high-dose melphalan and a single infusion (Day 0) (concurrent control group). The primary endpoint was number of days with ANC <500K/mcL. Symptom burden was assessed using the MSK-modified MD Anderson Symptom Inventory. Median duration of neutropenia was similar in study (4 days, range 3-5) and control patients (4 days, range 3-9) (p = 0.654). There was no significant difference in the number of red cell or platelet transfusions, days of fever, diarrhea, antibiotics, number of documented infections, or length of admission. Symptom burden surveys showed that AHCT was well-tolerated in both study and control patients. We conclude that fractionated stem cell infusions following high-dose melphalan do not enhance engraftment kinetics or significantly alter patients' clinical course following AHCT in PCM.

Melphalan, prednisone, and lenalidomide versus melphalan, prednisone, and thalidomide in untreated multiple myeloma.
    Blood, 2016, Mar-03, Volume: 127, Issue:9

    The combination of melphalan, prednisone, and thalidomide (MPT) is considered standard therapy for newly diagnosed patients with multiple myeloma who are ineligible for stem cell transplantation. Long-term treatment with thalidomide is hampered by neurotoxicity. Melphalan, prednisone, and lenalidomide, followed by lenalidomide maintenance therapy, showed promising results without severe neuropathy emerging. We randomly assigned 668 patients between nine 4-week cycles of MPT followed by thalidomide maintenance until disease progression or unacceptable toxicity (MPT-T) and the same MP regimen with thalidomide being replaced by lenalidomide (MPR-R). This multicenter, open-label, randomized phase 3 trial was undertaken by Dutch-Belgium Cooperative Trial Group for Hematology Oncology and the Nordic Myeloma Study Group (the HOVON87/NMSG18 trial). The primary end point was progression-free survival (PFS). A total of 318 patients were randomly assigned to receive MPT-T, and 319 received MPR-R. After a median follow-up of 36 months, PFS with MPT-T was 20 months (95% confidence interval [CI], 18-23 months) vs 23 months (95% CI, 19-27 months) with MPR-R (hazard ratio, 0.87; 95% CI, 0.72-1.04; P = .12). Response rates were similar, with at least a very good partial response of 47% and 45%, respectively. Hematologic toxicity was more pronounced with MPR-R, especially grades 3 and 4 neutropenia: 64% vs 27%. Neuropathy of at least grade 3 was significantly higher in the MPT-T arm: 16% vs 2% in MPR-R, resulting in a significant shorter duration of maintenance therapy (5 vs 17 months in MPR-R), irrespective of age. MPR-R has no advantage over MPT-T concerning efficacy. The toxicity profile differed with clinically significant neuropathy during thalidomide maintenance vs myelosuppression with MPR.

A phase 2 study of three low-dose intensity subcutaneous bortezomib regimens in elderly frail patients with untreated multiple myeloma.
    Leukemia, 2016, Volume: 30, Issue:6

    This phase 2 trial evaluated three low-dose intensity subcutaneous bortezomib-based treatments in patients ⩾75 years with newly diagnosed multiple myeloma (MM). Patients received subcutaneous bortezomib plus oral prednisone (VP, N=51) or VP plus cyclophosphamide (VCP, N=51) or VP plus melphalan (VMP, N=50), followed by bortezomib maintenance, and half of the patients were frail. Response rate was 64% with VP, 67% with VCP and 86% with VMP, and very good partial response rate or better was 26%, 28.5% and 49%, respectively. Median progression-free survival was 14.0, 15.2 and 17.1 months, and 2-year OS was 60%, 70% and 76% in VP, VCP, VMP, respectively. At least one drug-related grade ⩾3 non-hematologic adverse event (AE) occurred in 22% of VP, 37% of VCP and 33% of VMP patients; the discontinuation rate for AEs was 12%, 14% and 20%, and the 6-month rate of toxicity-related deaths was 4%, 4% and 8%, respectively. The most common grade ⩾3 AEs included infections (8-20%), and constitutional (10-14%) and cardiovascular events (4-12%); peripheral neuropathy was limited (4-6%). Bortezomib maintenance was effective and feasible. VP, VCP and VMP regimens demonstrated no substantial difference. Yet, toxicity was higher with VMP, suggesting that a two-drug combination followed by maintenance should be preferred in frail patients.

Single versus tandem high-dose melphalan followed by autologous blood stem cell transplantation in multiple myeloma: long-term results from the phase III GMMG-HD2 trial.
    British journal of haematology, 2016, Volume: 173, Issue:5

    The prospective, randomized phase III trial GMMG-HD2 aimed at demonstrating non-inferiority of single (Arm A) versus tandem (Arm B) high-dose melphalan followed by autologous transplantation (HDM/ASCT) with regard to 2-year event-free survival (EFS) in newly-diagnosed multiple myeloma (MM) and included 358 evaluable patients [Intention-to-treat population, (ITT), single/tandem HDM/ASCT: n = 177/181]. After a median follow-up of more than 11 years, non-inferiority of single versus tandem HDM/ASCT was demonstrated using the planned non-inferiority threshold of 15% of the 2-year EFS rate. Neither EFS (P = 0·53) nor overall survival (OS) (P = 0·33) differences were observed in the ITT population. In the tandem arm, 26% (n = 47/181) of patients refused a second HDM/ASCT due to non-medical reasons. A per-protocol (PP) analysis, including patients who received the intervention (single/tandem HDM/ASCT: n = 156/93) and patients who did not receive a second HDM/ASCT due to medical reasons (12%, n = 22/181), did not yield differences in EFS (P = 0·61) or OS (P = 0·16). In the ITT and PP set of the tandem arm, the rates of complete responses increased from first to second HDM/ASCT (both P = 0·04). Ten-year OS for the entire ITT was 34% (95% confidence interval: 29-40%). OS after first relapse was significantly shortened in the tandem arm (P = 0·04). In this study single HDM/ASCT was non-inferior to tandem HDM/ASCT in MM.

A phase II, single-arm, prospective study of bendamustine plus melphalan conditioning for second autologous stem cell transplantation in de novo multiple myeloma patients through a tandem transplant strategy.
    Bone marrow transplantation, 2016, Volume: 51, Issue:9

    This phase II trial evaluates, for the first time, the safety and efficacy of bendamustine plus high-dose melphalan (HDM) as a conditioning regimen before the second autologous stem cell transplantation (ASCT) in previously untreated multiple myeloma (MM) patients. In total, 32 ASCT patients received HDM (200 mg/m(2)) as conditioning for the first ASCT. After 3-6 months from the first ASCT, responding patients underwent a second ASCT following bendamustine (200 mg/m(2)) and HDM (140 mg/m(2)). High-dose chemotherapy and ASCT were performed with complete neutrophil and platelet recovery in all patients. The median number of days to neutrophil and platelet engraftment was 11 (range 9-15) and 12 (range 10-19), respectively. Only one subject experienced grade 3 diarrhea; the rate of mucositis and vomiting was significantly lower with the bendamustine plus HDM regimen compared with the HDM-only regimen (81.2 vs 96.9%, P=0.025 and 78.1 vs 100%, P=0.008). Overall response rate (ORR) was 81.2% after the first transplant, and 90.6% after the second, while complete response rates were 46.8 and 62.5%, respectively (P=0.016). Actuarial 2-year PFS and OS were 79% (95% confidence interval (CI), 60-98) and 97% (95% CI, 91-100), respectively. Bendamustine+HDM is feasible as the conditioning regimen for second ASCT in MM patients. The present study may pave the way for phase III studies specifically aimed at further investigating this combination strategy. The role of this combination in MM for conditioning regimen in a first or single ASCT setting should be also investigated.

Minimal residual disease monitoring and immune profiling in multiple myeloma in elderly patients.
    Blood, 2016, 06-23, Volume: 127, Issue:25

    The value of minimal residual disease (MRD) in multiple myeloma (MM) has been more frequently investigated in transplant-eligible patients than in elderly patients. Because an optimal balance between treatment efficacy and toxicity is of utmost importance in patients with elderly MM, sensitive MRD monitoring might be particularly valuable in this patient population. Here, we used second-generation 8-color multiparameter-flow cytometry (MFC) to monitor MRD in 162 transplant-ineligible MM patients enrolled in the PETHEMA/GEM2010MAS65 study. The transition from first- to second-generation MFC resulted in increased sensitivity and allowed us to identify 3 patient groups according to MRD levels: MRD negative (<10(-5); n = 54, 34%), MRD positive (between <10(-4) and ≥10(-5); n = 20, 12%), and MRD positive (≥10(-4); n = 88, 54%). MRD status was an independent prognostic factor for time to progression (TTP) (hazard ratio [HR], 2.7; P = .007) and overall survival (OS) (HR, 3.1; P = .04), with significant benefit for MRD-negative patients (median TTP not reached, 70% OS at 3 years), and similar poorer outcomes for cases with MRD levels between <10(-4) and ≥10(-5) vs ≥10(-4) (both with a median TTP of 15 months; 63% and 55% OS at 3 years, respectively). Furthermore, MRD negativity significantly improved TTP of patients >75 years (HR, 4.8; P < .001), as well as those with high-risk cytogenetics (HR, 12.6; P = .01). Using second-generation MFC, immune profiling concomitant to MRD monitoring also contributed to identify patients with poor, intermediate, and favorable outcomes (25%, 61%, and 100% OS at 3 years, respectively; P = .01), the later patients being characterized by an increased compartment of mature B cells. Our results show that similarly to transplant candidates, MRD monitoring is one of the most relevant prognostic factors in elderly MM patients, irrespectively of age or cytogenetic risk.

Busulfan, Melphalan, and Bortezomib versus High-Dose Melphalan as a Conditioning Regimen for Autologous Hematopoietic Stem Cell Transplantation in Multiple Myeloma.
    Biology of blood and marrow transplantation : journal of the American Society for Blood and Marrow Transplantation, 2016, Volume: 22, Issue:8

    High-dose melphalan 200 mg/m(2) (MEL 200) is the standard of care as a conditioning regimen for autologous hematopoietic stem cell transplantation (AHSCT) for multiple myeloma (MM). We compared a novel conditioning combination incorporating busulfan, melphalan, and bortezomib (BUMELVEL) versus standard MEL 200 in newly diagnosed patients undergoing AHSCT for MM. Between July 2009 and May 2012, 43 eligible patients received BUMELVEL conditioning followed by AHSCT. BU was administered i.v. daily for 4 days to achieve a target area under the concentration-time curve total of 20,000 mM·min based on pharmacokinetic analysis after the first dose. MEL 140 mg/m(2) (MEL 140) and VEL 1.6 mg/m(2) were administered i.v. on days -2 and -1, respectively. Outcomes were compared with a contemporaneous North American cohort (n = 162) receiving MEL 200 matched for age, sex, performance status, stage, interval from diagnosis to AHSCT, and disease status before AHSCT. Multivariate analysis of relapse, progression-free survival (PFS), and overall survival (OS) was performed. The median follow-up was 25 months. No transplant-related mortality was observed in the study cohort at 1 year. PFS at 1 year was superior in the BUMELVEL cohort (90%) in comparison with 77% in MEL 200 historical control subjects (P = .02). Cumulative incidence of relapse was lower in the BUMELVEL group versus the MEL 200 group (10% at 1 year versus 21%; P = .047). OS at 1 year was similar between cohorts (93% versus 93%; P = .89). BU can be safely combined with MEL 140 and VEL without an increase in toxicities or transplant-related mortality. We observed a superior PFS in the BUMELVEL cohort without maintenance therapy, warranting further trials.

Updated Outcomes and Impact of Age With Lenalidomide and Low-Dose Dexamethasone or Melphalan, Prednisone, and Thalidomide in the Randomized, Phase III FIRST Trial.
    Journal of clinical oncology : official journal of the American Society of Clinical Oncology, 2016, 10-20, Volume: 34, Issue:30

    Purpose This analysis of the FIRST trial in patients with newly diagnosed multiple myeloma (MM) ineligible for stem-cell transplantation examined updated outcomes and impact of patient age. Patients and Methods Patients with untreated symptomatic MM were randomly assigned at a one-to-one-to-one ratio to lenalidomide plus low-dose dexamethasone until disease progression (Rd continuous), Rd for 72 weeks (18 cycles; Rd18), or melphalan, prednisone, and thalidomide (MPT; 72 weeks), stratified by age (≤ 75 v > 75 years), disease stage (International Staging System stage I/II v III), and country. The primary end point was progression-free survival. Rd continuous and MPT were primary comparators. Results Between August 21, 2008, and March 7, 2011, 1,623 patients were enrolled (Rd continuous, n = 535; Rd18, n = 541; MPT, n = 547), including 567 (35%) age older than 75 years. Higher rates of advanced-stage disease and renal impairment were observed in patients older than 75 versus 75 years of age or younger. Rd continuous reduced the risk of progression or death compared with MPT by 31% (hazard ratio [HR], 0.69; 95% CI, 0.59 to 0.80; P < .001) overall, 36% (HR, 0.64; 95% CI, 0.53 to 0.77; P < .001) in patients age 75 years or younger, and 20% (HR, 0.80; 95% CI, 0.62 to 1.03; P = .084) in those age older than 75 years. Median overall survival was longer with Rd continuous than with MPT, including a 14-month difference in patients age older than 75 years. Progression-free survival with Rd18 was similar to that with MPT, and overall survival with Rd18 was marginally inferior to that with Rd continuous. Rates of grade 3 to 4 treatment-emergent adverse events were similar for Rd continuous-treated patients age 75 years or older and those age older than 75 years; however, older patients had more frequent lenalidomide dose reductions. Conclusion Results support Rd continuous treatment as a new standard of care for stem-cell transplantation-ineligible patients with newly diagnosed MM of all ages.

Dose-dense and less dose-intense Total Therapy 5 for gene expression profiling-defined high-risk multiple myeloma.
    Blood cancer journal, 2016, 07-29, Volume: 6, Issue:7

    Multiple myeloma (MM) is a heterogeneous disease with high-risk patients progressing rapidly despite treatment. Various definitions of high-risk MM are used and we reported that gene expression profile (GEP)-defined high risk was a major predictor of relapse. In spite of our best efforts, the majority of GEP70 high-risk patients relapse and we have noted higher relapse rates during drug-free intervals. This prompted us to explore the concept of less intense drug dosing with shorter intervals between courses with the aim of preventing inter-course relapse. Here we report the outcome of the Total Therapy 5 trial, where this concept was tested. This regimen effectively reduced early mortality and relapse but failed to improve progression-free survival and overall survival due to relapse early during maintenance.

Autotransplant with and without induction chemotherapy in older multiple myeloma patients: long-term outcome of a randomized trial.
    Haematologica, 2016, Volume: 101, Issue:11

    Autologous transplantation is controversial for older patients with multiple myeloma. The role of age-adjusted high-dose melphalan and the impact of induction chemotherapy cycles is still unclear. A total of 434 patients aged 60-70 years were randomly assigned to 4 cycles of standard anthracycline-based induction chemotherapy or no induction. For all patients, double autologous transplantation after melphalan 140 mg/m

Efficacy of cryotherapy associated with laser therapy for decreasing severity of melphalan-induced oral mucositis during hematological stem-cell transplantation: a prospective clinical study.
    Hematological oncology, 2015, Volume: 33, Issue:3

    Melphalan followed by hematopoietic stem-cell transplantation (HSCT) is the standard treatment for multiple myeloma and other hematopoietic neoplasms. However, high doses of melphalan cause severe oral mucositis (OM). The objective was to verify the efficacy of cryotherapy plus laser therapy on reduction of OM severity. HSCT patients undergoing melphalan chemotherapy (n = 71) were randomly divided into two groups according to OM treatment: oral cryotherapy performed with ice chips for 1 h 35 min followed by low-level laser therapy (InGaAIP, 660 nm, 40 mW, 6 J/cm(2) ) (n = 54) and laser therapy alone with the same protocol (n = 17). A control group (n = 33) was composed of HSCT patients treated with melphalan who received no specific treatment for OM. OM scores and clinical information were collected from D0 to D + 11. The cryotherapy/laser therapy group showed the lowest OM scores (maximum Grade I) and the lowest mean number of days (8 days) with OM in comparison with the other groups (p < 0.001). OM Grades III and IV were present with high frequency only in the control group. The association of cryotherapy with laser therapy was effective in reducing OM severity in HSCT patients who underwent melphalan conditioning.

Second autologous stem cell transplant: an effective therapy for relapsed multiple myeloma.
    Biology of blood and marrow transplantation : journal of the American Society for Blood and Marrow Transplantation, 2015, Volume: 21, Issue:3

    Therapeutic options for patients with multiple myeloma (MM) whose disease has relapsed after a prior autologous stem cell transplant (ASCT) include an expanding armamentarium of novel agents, often combined with traditional chemotherapy, or a second ASCT, with no clear standard of care. We retrospectively analyzed the outcomes of 75 patients who underwent salvage melphalan-based ASCT for relapsed MM at Memorial Sloan-Kettering Cancer Center between 1995 and 2012. Conditioning was performed with melphalan 200 mg/m(2) (n = 43), 180 mg/m(2) (n = 1), 140 mg/m(2) (n = 22), and 100 mg/m(2) (n = 9). The median age at second ASCT was 59 years (range, 36 to 75), and 58% (n = 35) were men. Of those with available data, 19% had high-risk cytogenetics (including t (4;14), p53 loss, or del 13q by karyotype) at the time of second ASCT. Median interval between first and salvage ASCT was 37.5 months (range, 6.9 to 111.4). Of 72 assessable patients, 57% had chemotherapy-sensitive disease before to salvage ASCT and 43% were chemoresistant. Four patients died within 100 days of ASCT. Response was assessed at 2 to 3 months post-ASCT, and of 71 assessable patients, 82% achieved at least a partial response, 15% had stable disease, and 3% progressed despite salvage ASCT. After salvage ASCT, 38 patients received maintenance therapy and 14 went on to allogeneic ASCT. The median progression-free survival (PFS) after second autograft was 10.1 months (95% confidence interval [CI], 7.6 to 13.4) and median overall survival (OS) 22.7 months (95% CI, 19.2 to 41.2). Patients with chemosensitive relapse had a trend toward better PFS (hazard ratio [HR], .60 [95% CI, .36 to 1.02]; P = .058) and significantly longer OS (HR, .49 [95% CI, .27 to .88]; P = .017) than patients with resistant relapse. Those with high-risk cytogenetics at the time of second ASCT had higher risk of death (HR, 2.98 [95% CI, 1.28 to 6.97]; P = .012) compared with patients with standard-risk cytogenetics. Salvage ASCT is an effective strategy for relapsed MM with chemosensitive disease and results in comparable PFS and OS to other salvage strategies.

Effect of cumulative bortezomib dose on survival in multiple myeloma patients receiving bortezomib-melphalan-prednisone in the phase III VISTA study.
    American journal of hematology, 2015, Volume: 90, Issue:4

    This analysis, using data from the bortezomib-melphalan-prednisone (VMP) arm of the Phase III VISTA study, investigated whether increased cumulative bortezomib dose could improve overall survival (OS) in transplant-ineligible patients with previously untreated multiple myeloma. Median cumulative bortezomib dose received by the 340 patients was 39 mg/m(2); this was selected as the cut-off for defining the dose groups to be compared for OS. Patient characteristics were well balanced between dose groups except for age. OS was significantly longer in the higher (≥39 mg/m(2)) versus lower (<39 mg/m(2)) cumulative bortezomib dose group (median 66.3 vs. 46.2 months; hazard ratio (HR) 0.533, P < 0.0001; age-adjusted HR 0.561, P = 0.0002). To overcome confounding effects of early discontinuations/deaths, which were more common in the lower cumulative dose group (27 vs. 4% of patients discontinued due to adverse events (AEs) in the lower and higher cumulative dose groups, respectively), a landmark analysis was conducted at 180 days, eliminating patients who died or discontinued before this time from the analysis. OS from this landmark remained significantly longer in the higher dose group (median 60.4 vs. 50.3 months; HR 0.709, P = 0.0372). Thus, higher cumulative bortezomib dose, reflecting prolonged treatment duration and/or dose intensity, appears associated with improved OS. Approaches to achieve higher cumulative doses could include subcutaneous bortezomib administration, dose/schedule modifications, continuing therapy in responding patients, and proactive AE management.

Health-related quality-of-life in patients with newly diagnosed multiple myeloma in the FIRST trial: lenalidomide plus low-dose dexamethasone versus melphalan, prednisone, thalidomide.
    Haematologica, 2015, Volume: 100, Issue:6

    We compared the health-related quality-of-life of patients with newly diagnosed multiple myeloma aged over 65 years or transplant-ineligible in the pivotal, phase III FIRST trial. Patients received: i) continuous lenalidomide and low-dose dexamethasone until disease progression; ii) fixed cycles of lenalidomide and low-dose dexamethasone for 18 months; or iii) fixed cycles of melphalan, prednisone, thalidomide for 18 months. Data were collected using the validated questionnaires (QLQ-MY20, QLQ-C30, and EQ-5D). The analysis focused on the EQ-5D utility value and six domains pre-selected for their perceived clinical relevance. Lenalidomide and low-dose dexamethasone, and melphalan, prednisone, thalidomide improved patients' health-related quality-of-life from baseline over the duration of the study across all pre-selected domains of the QLQ-C30 and EQ-5D. In the QLQ-MY20, lenalidomide and low-dose dexamethasone demonstrated a significantly greater reduction in the Disease Symptoms domain compared with melphalan, prednisone, thalidomide at Month 3, and significantly lower scores for QLQ-MY20 Side Effects of Treatment at all post-baseline assessments except Month 18. Linear mixed-model repeated-measures analyses confirmed the results observed in the cross-sectional analysis. Continuous lenalidomide and low-dose dexamethasone delays disease progression versus melphalan, prednisone, thalidomide and has been associated with a clinically meaningful improvement in health-related quality-of-life. These results further establish continuous lenalidomide and low-dose dexamethasone as a new standard of care for initial therapy of myeloma by demonstrating superior health-related quality-of-life during treatment, compared with melphalan, prednisone, thalidomide.

Phase 1/2 study of carfilzomib plus melphalan and prednisone in patients aged over 65 years with newly diagnosed multiple myeloma.
    Blood, 2015, May-14, Volume: 125, Issue:20

    This phase 1/2 dose-escalation study investigated the combination of carfilzomib with melphalan and prednisone (CMP) in patients aged >65 years with newly diagnosed multiple myeloma (MM). Melphalan and prednisone were administered orally on days 1 to 4; carfilzomib was IV administered on days 1, 2, 8, 9, 22, 23, 29, and 30 of a 42-day cycle. Patients received up to 9 cycles of CMP. In the phase 1 dose-escalation portion, the primary objectives were to determine the incidence of dose-limiting toxicities during the first cycle of CMP treatment to define the maximal tolerated dose (MTD) of carfilzomib. In the phase 2 portion, the primary objective was to evaluate the overall response rate (ORR) of CMP. In the phase 1 portion of the study, 24 patients received CMP at carfilzomib dosing levels of 20 mg/m(2), 27 mg/m(2), 36 mg/m(2), and 45 mg/m(2). The MTD was established as 36 mg/m(2). In the phase 2 portion of the study, 44 patients were enrolled at the MTD. Among 50 efficacy-evaluable patients treated at the MTD, the ORR was 90%. The projected 3-year overall survival rate was 80%. The combination of CMP was observed to be effective in elderly patients with newly diagnosed MM. This trial was registered at www.clinicaltrials.gov as #NCT01279694 (Eudract identifier 2010-019462-92).

High-Dose Melphalan Plus Thiotepa as Conditioning Regimen before Second Autologous Stem Cell Transplantation for "De Novo" Multiple Myeloma Patients: A Phase II Study.
    Biology of blood and marrow transplantation : journal of the American Society for Blood and Marrow Transplantation, 2015, Volume: 21, Issue:11

    High-dose melphalan (MEL) is the standard therapy for autologous stem cell transplantation (ASCT) in multiple myeloma (MM), although the optimal conditioning regimen remains yet to be identified. Thiotepa (THIO) appears to be a potentially effective option, with broad-spectrum antitumor efficacy that can be added to myeloablative multiagent regimens for ASCT in hematopoietic tumors. We conducted a phase II trial, adding THIO (275 mg/m(2)) to high-dose MEL (140 mg/m(2)) before a second ASCT, in a tandem ASCT strategy, in 64 patients with "de novo" MM. Overall, there was no transplant-related mortality. The incidence of neutropenic fever and mucositis (grades 3 to 4) was 39% and 9%, respectively. Median number of days to neutrophil and platelet engraftment were 11 and 12, respectively. After the second transplantation, the complete response improved to 43.8%. Overall response rate was 86%. After a median follow-up of 18.1 months, 13 patients had progressed and 3 died from MM. Median progression-free survival was not reached, and actuarial 2-year rates of progression-free and overall survival were 71% and 88.9%, respectively. Our results suggest that THIO/MEL is a feasible and safe conditioning regimen for ASCT in MM and should be explored for efficacy in a phase III study.

Melphalan, prednisone, and thalidomide vs melphalan, prednisone, and lenalidomide (ECOG E1A06) in untreated multiple myeloma.
    Blood, 2015, Sep-10, Volume: 126, Issue:11

    This phase 3 trial (Eastern Cooperative Oncology Group [ECOG] E1A06) compared melphalan, prednisone, and thalidomide (MPT-T) with melphalan, prednisone, and lenalidomide (mPR-R) in patients with untreated multiple myeloma (MM). A noninferiority design was used, and inferiority was defined as a progression-free survival (PFS) hazard ratio (HR) of MPT-T/mPR-R ≤0.82. A total of 306 patients enrolled, with a median age of 75.7 years. Median follow-up was 40.7 months. Median time on therapy was 12.1 months and 23.1 months for the 46.6% of treated patients who received maintenance, with no differences by arm. Median PFS was 21 months on MPT-T and 18.7 months on mPR-R (HR, 0.84; 95% confidence interval, 0.64-1.09). Overall survival was 52.6 months (MPT-T) vs 47.7 months (mPR-R) (P = .476). Per-protocol response rates were 63.6% (MPT-T) and 59.9% (mPR-R) (P = .557). Grade ≥3 nonhematologic toxicity was 59.5% for MPT-T vs 40.0% for mPR-R (P = .001). Second malignancies were observed in 18 MPT-T patients vs 14 mPR-R patients. Quality-of-life analysis favored mPR-R by induction end (P = .007). Use of MPT-T or mPR-R in elderly patients with untreated MM demonstrates no statistical or clinically relevant differences in response rates, PFS, and OS; however, quality of life at end of induction was improved and lower toxicity reported with mPR-R. This trial was registered at www.clinicaltrials.gov as #NCT00602641.

Continuous Therapy Versus Fixed Duration of Therapy in Patients With Newly Diagnosed Multiple Myeloma.
    Journal of clinical oncology : official journal of the American Society of Clinical Oncology, 2015, Oct-20, Volume: 33, Issue:30

    Continuous therapy (CT) prolongs progression-free survival 1 (PFS1; time from random assignment until the first progression or death), but chemotherapy-resistant relapse may negatively impact overall survival (OS). Progression-free survival 2 (PFS2; time from random assignment until the second progression or death) may represent an additional tool to estimate outcome. This study evaluates the benefit of novel agent-based CT versus fixed duration of therapy (FDT) in patients with newly diagnosed myeloma.. We included patients enrolled onto three phase III trials that randomly assigned patients to novel agent-based CT versus FDT. Primary analyses were restricted to the intent-to-treat population eligible for CT (patients progression free and alive at 1 year after random assignment). Primary end points were PFS1, PFS2, and OS. All hazard ratios (HRs) and 95% CIs were adjusted for several potential confounders using Cox models.. In the pooled analysis of the three trials, 604 patients were randomly assigned to CT and 614 were assigned to FDT. Median follow-up was 52 months. In the intent-to-treat CT population, CT (n = 417), compared with FDT (n = 410), significantly improved PFS1 (median, 32 v 16 months, respectively; HR, 0.47; 95% CI, 0.40 to 0.56; P < .001), PFS2 (median, 55 v 40 months, respectively; HR, 0.61; 95% CI, 0.50 to 0.75; P < .001), and OS (4-year OS, 69% v 60%, respectively; HR, 0.69; 95% CI, 0.54 to 0.88; P = .003).. In this pooled analysis, CT significantly improved PFS1, PFS2, and OS. The improvement in PFS2 suggests that the benefit reported during first remission is not cancelled by a shorter second remission. PFS2 is a valuable end point to estimate long-term clinical benefit and should be included in future trials.

A Phase IIb, Multicenter, Open-Label, Safety, and Efficacy Study of High-Dose, Propylene Glycol-Free Melphalan Hydrochloride for Injection (EVOMELA) for Myeloablative Conditioning in Multiple Myeloma Patients Undergoing Autologous Transplantation.
    Biology of blood and marrow transplantation : journal of the American Society for Blood and Marrow Transplantation, 2015, Volume: 21, Issue:12

    Autologous stem cell transplantation (ASCT) after high-dose melphalan conditioning is considered a standard of care procedure for patients with multiple myeloma (MM). Current formulations of melphalan (eg, Alkeran for Injection [melphalan hydrochloride]; GlaxoSmithKline, Research Triangle Park, NC, USA) have marginal solubility and limited chemical stability upon reconstitution. Alkeran requires the use of propylene glycol as a co-solvent, which itself has been reported to cause such complications as metabolic/renal dysfunction and arrhythmias. EVOMELA (propylene glycol-free melphalan HCl; Spectrum Pharmaceuticals, Inc., Irvine, CA, USA) is a new i.v. melphalan formulation that incorporates Captisol (Ligand Pharmaceuticals, Inc., La Jolla, CA, USA), a specially modified cyclodextrin that improves the solubility and stability of melphalan and eliminates the need for propylene glycol. This new formulation has been shown to be bioequivalent to Alkeran. EVOMELA (200 mg/m(2)) was administered as 2 doses of 100 mg/m(2) each in a phase IIb, open-label, multicenter study to confirm its safety and efficacy as a high-dose conditioning regimen for patients with MM undergoing ASCT. At 5 centers, 61 patients (26 women) with a median age of 62 years (range, 32-73) were enrolled. All patients achieved myeloablation with a median time of 5 days post-ASCT, and all successfully achieved neutrophil and platelet engraftment with median times of 12 days post-ASCT and 13 days post-ASCT, respectively; treatment-related mortality on day 100 was 0%. Overall response rate (according to independent, blinded review) was high (100%), with an overall complete response rate of 21% (13% stringent complete response; 8% complete response) and overall partial response rate of 79% (61% very good partial response; 18% partial response). The incidence of grade 3 mucositis and stomatitis was low (10% and 5%, respectively) with no grade 4 mucositis or stomatitis reported (graded according to National Cancer Institute Common Terminology Criteria for Adverse Events). Based on investigators' assessment of mucositis using the World Health Organization (WHO) oral toxicity scale, 75% of patients had a shift in mucositis score from WHO grade 0 at baseline to a higher grade on study, of which 13% of patients reported WHO grade 3 as the worst post-treatment mucositis over the course of the study; there were no reports of WHO grade 4 mucositis during the study. This study confirms the efficacy and accept

Chemotherapy plus lenalidomide versus autologous transplantation, followed by lenalidomide plus prednisone versus lenalidomide maintenance, in patients with multiple myeloma: a randomised, multicentre, phase 3 trial.
    The Lancet. Oncology, 2015, Volume: 16, Issue:16

    High-dose melphalan plus autologous stem-cell transplantation (ASCT) is the standard approach in transplant-eligible patients with newly diagnosed myeloma. Our aims were to compare consolidation with high-dose melphalan plus ASCT versus chemotherapy (cyclophosphamide and dexamethasone) plus lenalidomide, and maintenance with lenalidomide plus prednisone versus lenalidomide alone.. We did an open-label, randomised, multicentre, phase 3 study at 59 centres in Australia, Czech Republic, and Italy. We enrolled transplant-eligible patients with newly diagnosed myeloma aged 65 years or younger. Patients received a common induction with four 28-day cycles of lenalidomide (25 mg, days 1-21) and dexamethasone (40 mg, days 1, 8, 15, and 22) and subsequent chemotherapy with cyclophosphamide (3 g/m(2)) followed by granulocyte colony-stimulating factor for stem-cell mobilisation and collection. Using a 2 × 2 partial factorial design, we randomised patients to consolidation with either chemotherapy plus lenalidomide (six cycles of cyclophosphamide [300 mg/m(2), days 1, 8, and 15], dexamethasone [40 mg, days 1, 8, 15, and 22], and lenalidomide [25 mg, days 1-21]) or two courses of high-dose melphalan (200 mg/m(2)) and ASCT. We also randomised patients to maintenance with lenalidomide (10 mg, days 1-21) plus prednisone (50 mg, every other day) or lenalidomide alone. A simple randomisation sequence was used to assign patients at enrolment into one of the four groups (1:1:1:1 ratio), but the treatment allocation was disclosed only when the patient reached the end of the induction and confirmed their eligibility for consolidation. Both the patient and the treating clinician did not know the consolidation and maintenance arm until that time. The primary endpoint was progression-free survival assessed by intention-to-treat. The trial is ongoing and some patients are still receiving maintenance. This study is registered at ClinicalTrials.gov, number NCT01091831.. 389 patients were enrolled between July 6, 2009, and May 6, 2011, with 256 eligible for consolidation (127 high-dose melphalan and ASCT and 129 chemotherapy plus lenalidomide) and 223 eligible for maintenance (117 lenalidomide plus prednisone and 106 lenalidomide alone). Median follow-up was 52·0 months (IQR 30·4-57·6). Progression-free survival during consolidation was significantly shorter with chemotherapy plus lenalidomide compared with high-dose melphalan and ASCT (median 28·6 months [95% CI 20·6-36·7] vs 43·3 months [33·2-52·2]; hazard ratio [HR] for the first 24 months 2·51, 95% CI 1·60-3·94; p<0·0001). Progression-free survival did not differ between maintenance treatments (median 37·5 months [95% CI 27·8-not evaluable] with lenalidomide plus prednisone vs 28·5 months [22·5-46·5] with lenalidomide alone; HR 0·84, 95% CI 0·59-1·20; p=0·34). Fewer grade 3 or 4 adverse events were recorded with chemotherapy plus lenalidomide than with high-dose melphalan and ASCT; the most frequent were haematological (34 [26%] of 129 patients vs 107 [84%] of 127 patients), gastrointestinal (six [5%] vs 25 [20%]), and infection (seven [5%] vs 24 [19%]). Haematological serious adverse events were reported in two (2%) patients assigned chemotherapy plus lenalidomide and no patients allocated high-dose melphalan and ASCT. Non-haematological serious adverse events were reported in 13 (10%) patients assigned chemotherapy plus lenalidomide and nine (7%) allocated high-dose melphalan and ASCT. During maintenance, adverse events did not differ between groups. The most frequent grade 3 or 4 adverse events were neutropenia (nine [8%] of 117 patients assigned lenalidomide plus prednisone vs 14 [13%] of 106 allocated lenalidomide alone), infection (eight [8%] vs five [5%]), and systemic toxicities (seven [6%] vs two [2%]). Non-haematological serious adverse events were reported in 13 (11%) patients assigned lenalidomide plus prednisone versus ten (9%) allocated lenalidomide alone. Four patients died because of adverse events, three from infections (two during induction and one during consolidation) and one because of cardiac toxic effects.. Consolidation with high-dose melphalan and ASCT remains the preferred option in transplant-eligible patients with multiple myeloma, despite a better toxicity profile with chemotherapy plus lenalidomide..

A phase 1/2 study of oral panobinostat combined with melphalan for patients with relapsed or refractory multiple myeloma.
    Annals of hematology, 2014, Volume: 93, Issue:1

    Panobinostat is a histone deacetylase inhibitor that has shown synergistic preclinical anti-myeloma activity when combined with other agents, recently exhibiting synergy with the alkylating agent melphalan (Sanchez et al., Leuk Res 35(3):373-379, 2011). This phase 1/2 trial investigated the safety and efficacy of panobinostat in combination with melphalan for relapsed/refractory multiple myeloma patients. There were four different trial treatment schedules due to tolerability issues, with the final treatment schedule (treatment schedule D) consisting of panobinostat (15 or 20 mg) and melphalan (0.05 or 0.10 mg/kg), both administered on days 1, 3, and 5 of a 28-day cycle. A total of 40 patients were enrolled; 3 in treatment schedule A, 9 in schedule B, 7 in schedule C, and finally 21 schedule D. Patients had been treated with a median of four regimens (range, 1-16) and two prior bortezomib-containing regimens (range, 0-9). Maximum-tolerated dose was established at 20 mg panobinostat and 0.05 mg/kg melphalan in treatment schedule D. Overall, 3 patients (7.5 %) achieved ≥partial response (two very good PRs and one PR) while 23 exhibited stable disease and 14 showed progressive disease. All three responders were enrolled in cohort 2 of treatment schedule B (panobinostat 20 mg thrice weekly continuously with melphalan 0.05 mg/kg on days 1, 3, and 5). Neutropenia and thrombocytopenia were common, with 30.8 and 23.1 % of patients exhibiting ≥grade 3, respectively. Panobinostat + melphalan appears to have tolerability issues in a dosing regimen capable of producing a response. Care must be taken to balance tolerability and efficacy with this combination.

Factors that influence health-related quality of life in newly diagnosed patients with multiple myeloma aged ≥ 65 years treated with melphalan, prednisone and lenalidomide followed by lenalidomide maintenance: results of a randomized trial.
    Leukemia & lymphoma, 2014, Volume: 55, Issue:7

    In the MM-015 trial, melphalan-prednisone-lenalidomide followed by lenalidomide maintenance (MPR-R) significantly prolonged progression-free survival versus melphalan-prednisone (MP) in newly diagnosed patients with multiple myeloma aged ≥ 65 years. Health-related quality of life (HRQoL), a secondary endpoint of MM-015, was also improved with MPR-R. This sub-analysis evaluated the impact of individual predictive factors on HRQoL. Patients completed HRQoL questionnaires at baseline, every third cycle and at progressive disease (PD)/treatment discontinuation. In a mixed-effects model female gender, advanced age and PD negatively affected HRQoL while better treatment responses showed positive effects. Compared to PD, HRQoL during MPR-R treatment was statistically significantly better in two of six preselected domains both of which were also clinically meaningful. HRQoL scores at end of treatment were all either improved or not statistically significantly different versus baseline. In conclusion, continuous treatment with MPR-R, which delays PD, appears to be associated with clinically meaningful improvements in HRQoL.

Bortezomib-melphalan-prednisone-thalidomide followed by maintenance with bortezomib-thalidomide compared with bortezomib-melphalan-prednisone for initial treatment of multiple myeloma: updated follow-up and improved survival.
    Journal of clinical oncology : official journal of the American Society of Clinical Oncology, 2014, Mar-01, Volume: 32, Issue:7

    Bortezomib-melphalan-prednisone (VMP) has improved overall survival in multiple myeloma. This randomized trial compared VMP plus thalidomide (VMPT) induction followed by bortezomib-thalidomide maintenance (VMPT-VT) with VMP in patients with newly diagnosed multiple myeloma.. We randomly assigned 511 patients who were not eligible for transplantation to receive VMPT-VT (nine 5-week cycles of VMPT followed by 2 years of VT maintenance) or VMP (nine 5-week cycles without maintenance).. In the initial analysis with a median follow-up of 23 months, VMPT-VT improved complete response rate from 24% to 38% and 3-year progression-free-survival (PFS) from 41% to 56% compared with VMP. In this analysis, median follow-up was 54 months. The median PFS was significantly longer with VMPT-VT (35.3 months) than with VMP (24.8 months; hazard ratio [HR], 0.58; P < .001). The time to next therapy was 46.6 months in the VMPT-VT group and 27.8 months in the VMP group (HR, 0.52; P < .001). The 5-year overall survival (OS) was greater with VMPT-VT (61%) than with VMP (51%; HR, 0.70; P = .01). Survival from relapse was identical in both groups (HR, 0.92; P = .63). In the VMPT-VT group, the most frequent grade 3 to 4 adverse events included neutropenia (38%), thrombocytopenia (22%), peripheral neuropathy (11%), and cardiologic events (11%). All of these, except for thrombocytopenia, were significantly more frequent in the VMPT-VT patients.. Bortezomib and thalidomide significantly improved OS in multiple myeloma patients not eligible for transplantation.

Evaluation of the serum free light chain (sFLC) analysis in prediction of response in symptomatic multiple myeloma patients: rapid profound reduction in involved FLC predicts achievement of VGPR.
    European journal of haematology, 2014, Volume: 93, Issue:5

    Observational data from clinical studies indicate that the goal of first-line therapy in newly diagnosed patients with symptomatic multiple myeloma (MM) should be very good partial response (VGPR) or better, preferably before high-dose treatment. We evaluated the value of early measurements of involved free light chains (iFLC) in prediction of high-quality responses. Measuring iFLC has a potential advantage due to a short half-life compared to the half-life of the M-protein.. In 36 multiple myeloma (MM) patients, we measured serial changes in iFLC and M-protein after start of treatment. iFLC and M-protein were measured before treatment, the following 5 wk days, 2, 3 and 6 wks after start of treatment.. Median iFLC and M-protein half-life was 2.75 and 11.9 d, respectively. All patients with an iFLC >75 mg/L had an initial significant reduction (>20%) in iFLC, even patients with no response to treatment. The mean per cent reduction in iFLC 3 d after start of treatment was 52.3% and 23.6% (P = 0.021) in patients achieving ≥VGPR and PR, respectively. The mean per cent reduction in M-protein in patients achieving ≥VGPR and PR was not significantly different in the 6-wk study period. As a predictor of VGPR, an 80% reduction in iFLC at day 21 resulted in a sensitivity of 87.5% and a specificity of 100%.. Changes in iFLC could be a tool for early identification of responders to anti-myeloma therapy. Early, sequential measurements of iFLC within the first week after start of treatment are not meaningful.

Phase 2 randomized study of bortezomib-melphalan-prednisone with or without siltuximab (anti-IL-6) in multiple myeloma.
    Blood, 2014, Jun-26, Volume: 123, Issue:26

    Because interleukin-6 (IL-6) is considered important in the proliferation of early multiple myeloma (MM), we hypothesized that the addition of the anti-IL-6 monoclonal antibody siltuximab to the bortezomib-melphalan-prednisone (VMP) regimen would improve outcomes in transplant-ineligible patients with newly diagnosed MM. One hundred and six patients were randomized to receive 9 cycles of VMP or VMP plus siltuximab (11 mg/kg every 3 weeks) followed by siltuximab maintenance. Baseline characteristics were well balanced except for immunoglobulin A subtype and 17p deletions. With a complete response (CR) rate of 27% on siltuximab plus VMP (S+VMP) and 22% on VMP, the study did not confirm its hypothesis that the addition of siltuximab would increase the CR rate by at least 10%. Overall response rate was 88% on S+VMP and 80% on VMP, and at least very good partial response rates were 71% and 51% (P = .0382), respectively. Median progression-free survival (17 months) and 1-year overall survival (88%) were identical in the 2 arms. Grade ≥3 adverse-event incidence was 92% on S+VMP and 81% on VMP (P = .09), with trends toward more hematologic events and infections on S+VMP. Maintenance therapy with siltuximab was well tolerated. In conclusion, the addition of siltuximab to VMP did not improve the CR rate or long-term outcomes. This study was registered at http://clinicaltrials.gov as #NCT00911859.

Aprepitant for the control of delayed nausea and vomiting associated with the use of high-dose melphalan for autologous peripheral blood stem cell transplants in patients with multiple myeloma: a phase II study.
    Supportive care in cancer : official journal of the Multinational Association of Supportive Care in Cancer, 2014, Volume: 22, Issue:11

    The aim of this study is to evaluate the efficacy of aprepitant as part of the antiemetic regimen for high-dose melphalan conditioning in multiple myeloma patients.. This is a prospective, single-arm study.. The study was conducted at an Academic Medical Facility.. Twenty-six patients receiving high-dose melphalan with autologous stem cell support were included in this study.. Eligible patients were >18 years with a diagnosis of MM undergoing high-dose melphalan followed by autologous peripheral blood stem cell transplantation (PBSCT). All patients had serum aminotransferases and total bilirubin less than 2× upper limit of normal. Treatment consisted of aprepitant 125 mg orally on day 1, followed by 80 mg orally 24 and 48 h after the initial dose; ondansetron 16 mg orally day 1; dexamethasone 12 mg orally day 1, and 8 mg orally days 2-4 with breakthrough medications as needed.. Patients were evaluated for the frequency of emetic episodes, the need for breakthrough antiemetic medication, and the mean nausea score in 24-h increments beginning 24 h after chemotherapy and continuing until 120 h. Nausea score was determined using a linear analog scale (0-10). Complete response (CR) was defined as no more than one (1) emetic episode during the evaluation period. A total of 26 patients (17 male, 9 female) were enrolled in the study. Of these, 25 (96 %) were complete responders and 24 (92 %) had no documented emetic episodes during the study period. One patient (4 %) had 1 emetic episode and one patient (4 %) had 2 emetic episodes. Some degree of nausea was reported by 23/26 patients, and the mean nausea score for the entire group over the study period was 0.7 (range 0-10).. Addition of aprepitant to standard antiemetics resulted in low rates of delayed nausea/vomiting associated with high-dose melphalan and PBSCT, and has now become standard practice in this patient population at our institution.

Phase IIa cross-over study of propylene glycol-free melphalan (LGD-353) and alkeran in multiple myeloma autologous transplantation.
    Bone marrow transplantation, 2014, Volume: 49, Issue:8

    Propylene Glycol-Free melphalan HCL for Injection (PGF-Mel) is a new formulation that incorporates Captisol, a specially modified cyclodextrin, to improve melphalan stability. In this phase IIa, open-label, randomized, cross-over design bioequivalence study, the pharmacokinetics of PGF-Mel were compared with the marketed formulation of melphalan, or Alkeran. Patients received half of the total dose of melphalan in the form of Alkeran and the other half in the form of PGF-Mel in an alternating manner. The pharmacokinetic measures were determined using WinNonlin 6.2 and bioequivalence was assessed using log-transformed systemic exposure parameters. Twenty-four patients, 11 females and 13 males, were enrolled between 4 February 2010 and 16 May 2011 at The University of Kansas Medical Center and The University of Kansas Cancer Center. The median age of enrolled subjects was 58 years (range: 48-65). All patients achieved myeloablation 3 days post autologous graft followed by successful neutrophil engraftment with a median of 11 days after transplant. Pharmacokinetic analysis showed that PGF-Mel was bioequivalent with Alkeran and also revealed that maximum plasma concentration (Cmax) and area under the plasma concentration-time curve (AUC) were higher (~10%) after PGF-Mel administration. In conclusion, PGF-Mel is considered bioequivalent to Alkeran while also demonstrating a marginally higher systemic drug exposure.

High-dose chemotherapy plus autologous stem-cell transplantation as consolidation therapy in patients with relapsed multiple myeloma after previous autologous stem-cell transplantation (NCRI Myeloma X Relapse [Intensive trial]): a randomised, open-label,
    The Lancet. Oncology, 2014, Volume: 15, Issue:8

    Relapsed multiple myeloma has no standard treatment, and the role of autologous stem-cell transplantation (ASCT) has not been fully defined. We aimed to compare high-dose melphalan plus salvage ASCT with cyclophosphamide in patients with relapsed multiple myeloma who had previously undergone ASCT.. This multicentre, randomised, open-label, phase 3 study recruited patients aged at least 18 years with multiple myeloma who needed treatment for first progressive or relapsed disease at least 18 months after a previous ASCT from 51 centres across the UK. Before randomisation, eligible patients received bortezomib, doxorubicin, and dexamethasone (PAD) induction therapy and then underwent peripheral blood stem-cell mobilisation and harvesting if applicable. Eligible patients (with adequate stem-cell harvest) were randomly assigned (1:1), using an automated telephone randomisation line, to either high-dose melphalan 200 mg/m(2) plus salvage ASCT or oral cyclophosphamide (400mg/m(2) per week for 12 weeks). Randomisation was stratified by length of first remission or plateau and response to PAD re-induction therapy. The primary endpoint was time to disease progression, analysed by intention to treat. This trial is registered with ClinicalTrials.gov, number NCT00747877, and EudraCT, number 2006-005890-24.. Between April 16, 2008, and Nov 19, 2012, 297 patients were registered, of whom 293 received PAD re-induction therapy. Between Aug 26, 2008, and Nov 16, 2012, 174 patients with sufficient PBSCs were randomised to salvage ASCT (n=89) or cyclophosphamide (n=85). After a median follow-up of 31 months (IQR 19-42), median time to progression was significantly longer in the salvage ASCT than in the cyclophosphamide group (19 months [95% CI 16-25] vs 11 months [9-12]; hazard ratio 0·36 [95% CI 0·25-0·53]; p<0·0001). Frequently reported (in >10% of patients) grade 3-4 adverse events with PAD induction, salvage ASCT, and cyclophosphamide were: neutropenia (125 [43%] of 293 patients after PAD, and 63 [76%] of 83 patients in the salvage ASCT group vs 11 [13%] of 84 patients in the cyclophosphamide group), thrombocytopenia (150 [51%] after PAD, and 60 [72%] vs four [5%], respectively), and peripheral neuropathy (35 [12%] after PAD, and none vs none, respectively).. This study provides evidence for the improved efficacy of high-dose melphalan plus salvage ASCT when compared with cyclophosphamide in patients with relapsed multiple myeloma eligible for intensive therapy, which might help to guide clinical decisions regarding the management of such patients..

Pharmacoeconomic implications of lenalidomide maintenance therapy in multiple myeloma.
    Oncology, 2014, Volume: 87, Issue:4

    We compared the three arms of the MM-015 randomized phase III clinical trial [melphalan and prednisone (MP), MP plus lenalidomide (MPR), and MPR plus lenalidomide maintenance (MPR-R)] to determine whether the addition of lenalidomide maintenance therapy for primary treatment of multiple myeloma is cost-effective. We used progression-free survival and adverse event data from the MM-015 study for the analysis. Two novel measures of cost-effectiveness termed the Average Cumulative Cost per Patient (ACCP) and the Average Cumulative Cost per Progression-Free Survivor (ACCPFS) were developed for the purpose of this analysis. The ACCP of MP was USD 18,218, compared to USD 167,862 for MPR and USD 309,173 for MPR-R. The ACCPFS was highest with MPR at USD 1,555,443, while MP was USD 313,592 and MPR-R was USD 690,111. MPR-R is superior to MPR in terms of preventing the first progression after initial therapy. However, the addition of lenalidomide to MP in the induction and also in the maintenance setting leads to significant costs.

A phase II study of V-BEAM as conditioning regimen before second auto-SCT for multiple myeloma.
    Bone marrow transplantation, 2014, Volume: 49, Issue:11

    High-dose melphalan has been the standard conditioning regimen for auto-SCT in multiple myeloma (MM) for decades. A more effective conditioning regimen may induce deeper responses and longer remission duration. It is especially needed in the setting of second auto-SCT, which rarely achieves comparable results with the first auto-SCT using the same conditioning regimen. Here we conducted a phase II study to investigate the efficacy and safety of a conditioning regimen V-BEAM (bortezomib-BEAM) before second auto-SCT for multiple myeloma. Ten patients were enrolled from September 2012 to May 2013. The CR rate at day +100 after auto-SCT was 75%; all except for one patient remained in remission after a median follow-up of 6 months. Three patients developed Clostridium difficile infection. Two patients died within the first 30 days of auto-SCT from neutropenic colitis and overwhelming sepsis, respectively. Due to the high rate of morbidity and mortality, the study was terminated after 10 patients. In summary, although the conditioning regimen V-BEAM before second auto-SCT for MM provided promising responses, it was associated with unexpected treatment-related toxicity and should not be investigated further without modifications.

GEM2005 trial update comparing VMP/VTP as induction in elderly multiple myeloma patients: do we still need alkylators?
    Blood, 2014, Sep-18, Volume: 124, Issue:12

    Melphalan (M), in combination with prednisone (MP), has been the backbone of new combinations, including bortezomib plus MP (VMP). However, new alkylator-free schemes, such as lenalidomide plus low-dose dexamethasone, are challenging the role of alkylators in myeloma treatment of elderly patients. Here we have updated, after a long follow-up (median 6 years), the results of the GEM2005 study that addressed this question by comparing VMP with bortezomib plus thalidomide and prednisone (VTP) as induction. Between April 2005 and October 2008, 260 patients were randomized to receive 6 cycles of VMP or VTP as induction. The median progression-free survival was 32 months for the VMP and 23 months for the VTP arms (P 5 .09). VMP significantly prolonged the overall survival (OS) compared with VTP (median of 63 and 43 months, respectively; hazard ratio [HR]: 0.67, P 5 .01). Achieving immunophenotypic complete response was associated with a significantly longer OS, especially in the VMP arm (66%remain alive after 8 years). Melphalan, plus bortezomib, should be maintained as standard care for the treatment of elderly multiple myeloma patients. This trial was registered at www.clinicaltrials.gov as #NCT00443235.

Autologous transplantation and maintenance therapy in multiple myeloma.
    The New England journal of medicine, 2014, Sep-04, Volume: 371, Issue:10

    This open-label, randomized, phase 3 study compared melphalan at a dose of 200 mg per square meter of body-surface area plus autologous stem-cell transplantation with melphalan-prednisone-lenalidomide (MPR) and compared lenalidomide maintenance therapy with no maintenance therapy in patients with newly diagnosed multiple myeloma.. We randomly assigned 273 patients 65 years of age or younger to high-dose melphalan plus stem-cell transplantation or MPR consolidation therapy after induction, and 251 patients to lenalidomide maintenance therapy or no maintenance therapy. The primary end point was progression-free survival.. The median follow-up period was 51.2 months. Both progression-free and overall survival were significantly longer with high-dose melphalan plus stem-cell transplantation than with MPR (median progression-free survival, 43.0 months vs. 22.4 months; hazard ratio for progression or death, 0.44; 95% confidence interval [CI], 0.32 to 0.61; P<0.001; and 4-year overall survival, 81.6% vs. 65.3%; hazard ratio for death, 0.55; 95% CI, 0.32 to 0.93; P=0.02). Median progression-free survival was significantly longer with lenalidomide maintenance than with no maintenance (41.9 months vs. 21.6 months; hazard ratio for progression or death, 0.47; 95% CI, 0.33 to 0.65; P<0.001), but 3-year overall survival was not significantly prolonged (88.0% vs. 79.2%; hazard ratio for death, 0.64; 95% CI, 0.36 to 1.15; P=0.14). Grade 3 or 4 neutropenia was significantly more frequent with high-dose melphalan than with MPR (94.3% vs. 51.5%), as were gastrointestinal adverse events (18.4% vs. 0%) and infections (16.3% vs. 0.8%); neutropenia and dermatologic toxic effects were more frequent with lenalidomide maintenance than with no maintenance (23.3% vs. 0% and 4.3% vs. 0%, respectively).. Consolidation therapy with high-dose melphalan plus stem-cell transplantation, as compared with MPR, significantly prolonged progression-free and overall survival among patients with multiple myeloma who were 65 years of age or younger. Lenalidomide maintenance, as compared with no maintenance, significantly prolonged progression-free survival. (Funded by Celgene; ClinicalTrials.gov number, NCT00551928.).

Lenalidomide and dexamethasone in transplant-ineligible patients with myeloma.
    The New England journal of medicine, 2014, Sep-04, Volume: 371, Issue:10

    The combination melphalan-prednisone-thalidomide (MPT) is considered a standard therapy for patients with myeloma who are ineligible for stem-cell transplantation. However, emerging data on the use of lenalidomide and low-dose dexamethasone warrant a prospective comparison of the two approaches.. We randomly assigned 1623 patients to lenalidomide and dexamethasone in 28-day cycles until disease progression (535 patients), to the same combination for 72 weeks (18 cycles; 541 patients), or to MPT for 72 weeks (547 patients). The primary end point was progression-free survival with continuous lenalidomide-dexamethasone versus MPT.. The median progression-free survival was 25.5 months with continuous lenalidomide-dexamethasone, 20.7 months with 18 cycles of lenalidomide-dexamethasone, and 21.2 months with MPT (hazard ratio for the risk of progression or death, 0.72 for continuous lenalidomide-dexamethasone vs. MPT and 0.70 for continuous lenalidomide-dexamethasone vs. 18 cycles of lenalidomide-dexamethasone; P<0.001 for both comparisons). Continuous lenalidomide-dexamethasone was superior to MPT for all secondary efficacy end points, including overall survival (at the interim analysis). Overall survival at 4 years was 59% with continuous lenalidomide-dexamethasone, 56% with 18 cycles of lenalidomide-dexamethasone, and 51% with MPT. Grade 3 or 4 adverse events were somewhat less frequent with continuous lenalidomide-dexamethasone than with MPT (70% vs. 78%). As compared with MPT, continuous lenalidomide-dexamethasone was associated with fewer hematologic and neurologic toxic events, a moderate increase in infections, and fewer second primary hematologic cancers.. As compared with MPT, continuous lenalidomide-dexamethasone given until disease progression was associated with a significant improvement in progression-free survival, with an overall survival benefit at the interim analysis, among patients with newly diagnosed multiple myeloma who were ineligible for stem-cell transplantation.

Aprepitant, granisetron, and dexamethasone for prevention of chemotherapy-induced nausea and vomiting after high-dose melphalan in autologous transplantation for multiple myeloma: results of a randomized, placebo-controlled phase III trial.
    Journal of clinical oncology : official journal of the American Society of Clinical Oncology, 2014, Oct-20, Volume: 32, Issue:30

    The optimal regimen to prevent chemotherapy-induced nausea and vomiting (CINV) for patients undergoing high-dose chemotherapy and autologous stem-cell transplantation (ASCT) is unclear. To evaluate the effect of aprepitant in addition to a standard regimen, we conducted this randomized, placebo-controlled phase III trial.. Patients with multiple myeloma were randomly assigned at a one-to-one ratio to receive either aprepitant (125 mg orally on day 1 and 80 mg orally on days 2 to 4), granisetron (2 mg orally on days 1 to 4), and dexamethasone (4 mg orally on day 1 and 2 mg orally on days 2 to 3) or matching placebo, granisetron (2 mg orally on days 1 to 4), and dexamethasone (8 mg orally on day 1 and 4 mg orally on days 2 to 3). Melphalan 100 mg/m(2) was administered intravenously on days 1 to 2. ASCT was performed on day 4. The primary end point (complete response) was defined as no emesis and no rescue therapy within 120 hours of melphalan administration. Quality of life was assessed by modified Functional Living Index-Emesis (FLIE) questionnaire on days -1 and 6.. Overall, 362 patients were available for the efficacy analysis (181 in each treatment arm). Significantly more patients receiving aprepitant reached the primary end point (58% v 41%; odds ratio [OR], 1.92; 95% CI, 1.23 to 3.00; P = .0042). Absence of major nausea (94% v 88%; OR, 2.37; 95% CI, 1.09 to 5.15; P = .026) and emesis (78% v 65%; OR, 1.99; 95% CI, 1.25 to 3.18; P = .0036) within 120 hours was increased by aprepitant. Mean total FLIE score (± standard deviation) was 114 ± 18 for aprepitant and 106 ± 26 for placebo (P < .001).. The addition of aprepitant resulted in significantly less CINV and had a positive effect on quality of life.

A phase 1 study of bendamustine and melphalan conditioning for autologous stem cell transplantation in multiple myeloma.
    Biology of blood and marrow transplantation : journal of the American Society for Blood and Marrow Transplantation, 2013, Volume: 19, Issue:5

    Bendamustine has efficacy in multiple myeloma with a toxicity profile limited to myelosuppression. We hypothesized that adding bendamustine to autologous stem cell transplant conditioning in myeloma would enhance response without significant additional toxicity. We conducted a phase 1 trial adding escalating doses of bendamustine to the current standard conditioning of melphalan 200 mg/m(2). Twenty-five subjects were enrolled into 6 cohorts. A maximum tolerated dose was not encountered and the highest dose level cohort of bendamustine 225 mg/m(2) + melphalan 200 mg/m(2) was expanded to further evaluate safety. Overall, there was no transplant related mortality and only one grade 4 dose-limiting toxicity was observed. Median number of days to neutrophil and platelet engraftment were 11 (range, 9 to 14) and 13 (range, 10 to 21), respectively. Disease responses at day +100 posttransplantation were progression in 5 (21%), partial response in 1 (4%), very good partial response in 7 (33%), complete response in 1 (4%), and stringent complete response in 9 (38%). Six patients (24%) with pre-existing high-risk disease died from progressive myeloma during study follow-up, all at or beyond 100 days after autologous stem cell transplant. Bendamustine up to a dose of 225 mg/m(2) added to autologous stem cell transplantation conditioning with high-dose melphalan in patients with multiple myeloma did not exacerbate expected toxicities.

Phase I/II study of bortezomib-melphalan-prednisolone for previously untreated Japanese patients with multiple myeloma.
    Cancer science, 2013, Volume: 104, Issue:7

    This phase I/II study was conducted to evaluate the safety and efficacy of bortezomib-melphalan-prednisolone in Japanese patients with previously untreated multiple myeloma who are ineligible for hematopoietic stem cell transplantation. One hundred and one patients were enrolled, and 99 patients received up to nine 6-week cycles of bortezomib (0.7/1.0/1.3 mg/m²) on days 1, 4, 8, 11, 22, 25, 29, and 32 in cycles 1-4 and on days 1, 8, 22, and 29 in cycles 5-9, with melphalan (9 mg/m²) and prednisolone (60 mg/m²) on days 1-4 of each cycle. The recommended dose was determined in the phase I portion, and the overall response rate and safety of bortezomib-melphalan-prednisolone at the recommended dose were assessed in the phase II portion. The recommended dose of bortezomib was determined to be 1.3 mg/m². Grade 3 or higher non-hematological adverse events included diarrhea (12%) and peripheral neuropathy (10%); grade 4 hematological adverse events included lymphopenia (41%), neutropenia (30%), and thrombocytopenia (22%). Eleven patients had lung injury associated with bortezomib; two had grade 3 disease, and the other nine had grade 1 or 2 disease. Of the 86 patients treated with 1.3-mg/m² bortezomib in phases I and II, the median number of treatment cycles was 4.5, and the overall response rate was 70% (95% confidence interval: 59-79%). Bortezomib-melphalan-prednisolone with 1.3-mg/m² bortezomib was considered to be tolerable and effective in Japanese patients with previously untreated multiple myeloma. However, further investigation is needed to refine the administration schedule.

Phase II clinical trial for the evaluation of bortezomib within the reduced intensity conditioning regimen (RIC) and post-allogeneic transplantation for high-risk myeloma patients.
    British journal of haematology, 2013, Volume: 162, Issue:4

    The current study was designed to assess the safety and efficacy of bortezomib in combination with fludarabine and melphalan as reduced intensity conditioning before allogeneic stem cell transplantation in patients with high risk multiple myeloma. Sixteen patients were evaluable. The median number of previous line of treatment was 3; all patients had relapsed following a prior autograft and 13 had previously received bortezomib. Fifteen of them either remained stable or improved disease status at day +100 post-transplant, including 11 patients with active disease. More specifically, nine patients (56%) and five patients (31%) reached complete remission and partial response, respectively. 25% developed grade III acute graft-versus-host disease. The cumulative incidence of non-relapse mortality, relapse and overall survival were 25%, 54% and 41%, respectively, at 3 years. Regarding the non-haematological toxicity (grade>2), two patients developed peripheral neuropathy, two patients liver toxicity and 1 pulmonary toxicity early post-transplant. The haematological toxicity was only observed during the first three cycles mostly related to low haemoglobin and platelet levels. The current trial is the first one evaluating the safety and efficacy of bortezomib as part of a reduced intensity conditioning regimen among patients with high risk multiple myeloma.

Bortezomib induction, reduced-intensity transplantation, and lenalidomide consolidation-maintenance for myeloma: updated results.
    Blood, 2013, Aug-22, Volume: 122, Issue:8

    A sequential approach including bortezomib induction, intermediate-dose melphalan, and autologous stem cell transplantation (ASCT), followed by lenalidomide consolidation-maintenance, has been evaluated. Efficacy and safety data have been analyzed on intention-to-treat and results updated. Newly diagnosed myeloma patients 65 to 75 years of age (n = 102) received 4 cycles of bortezomib-pegylated liposomal doxorubicin-dexamethasone, tandem melphalan (100 mg/m(2)) followed by ASCT (MEL100-ASCT), 4 cycles of lenalidomide-prednisone consolidation (LP), and lenalidomide maintenance (L) until disease progression. The complete response (CR) rate was 33% after MEL100-ASCT, 48% after LP and 53% after L maintenance. After a median follow-up of 66 months, median time-to-progression (TTP) was 55 months and median progression-free survival 48 months. Median overall survival (OS) was not reached, 5-year OS was 63%. In CR patients, median TTP was 70 months and 5-year OS was 83%. Median survival from relapse was 28 months. Death related to adverse events (AEs) occurred in 8/102 patients during induction or transplantation. Rate of death related to AEs was higher in patients ≥70 years compared with younger (5/26 vs 3/76, P = .024). Bortezomib-induction followed by ASCT and lenalidomide consolidation-maintenance is a valuable option for elderly myeloma patients, with the greatest benefit in those younger than 70 years of age.

Modeling of experts' divergent prior beliefs for a sequential phase III clinical trial.
    Clinical trials (London, England), 2013, Volume: 10, Issue:4

    There have been few Bayesian analyses of phase III sequential clinical trials that model divergent expert opinions in a single distribution.. We used modeling of experts' opinions to perform additional Bayesian analyses of a randomized clinical trial (designed as a sequential trial), particularly when a bimodal shape is observed. We provide an illustrative example based on a randomized trial conducted in patients aged between 65 and 75 years with multiple myeloma as the case study.. The main endpoint of the trial was overall survival (OS). Prior distribution of the log hazard ratio of death in the experimental versus the control arm ( $$\\theta $$ ) was constructed based on elicitation of experts using a mixture of normal distributions estimated by the Expectation-Maximisation (EM) algorithm. At each interim and terminal analysis, the posterior probability of $$\\theta $$ and the resulting increases in median OS in the experimental arm compared to the control were computed. The results were compared to results obtained using either skeptical, enthusiastic, or a mixture of those priors. Finally, we discuss our results in light of the frequentist approach originally designed for the trial.. A total of 39 experts reported their opinion on the median OS in the experimental arm compared to the median control survival of 30 months. The resulting pooled distribution of the log hazard ratios exhibited a bimodal profile. When the prior mixture of the normal distribution was fitted to the data sets from the experts, 44% of the experts' opinions were optimistic and 56% were doubtful. At the final analysis, the percentage of doubting experts dropped to 18%. This corresponded to a posterior probability of an improved OS in the experimental arm compared to the control arm of at least 0.98, regardless of the prior. These findings are in agreement with the original conclusion of the trial regarding the beneficial effect of the experimental treatment in this population.. Only 39 experts among the 120 questioned physicians responded to the inquiry. Our approach was hybrid because the prior mixture was estimated using the EM algorithm, and a full Bayesian approach may have been used.. Bayesian inference allows the quantification of increased survival in terms of probability distributions and provides investigators with an additional tool in the analysis of a randomized phase III clinical trial. Using a mixture of densities appears to be a promising strategy for incorporating the bimodal profile of prior opinion, with actualization of the two components along the trial as an illustration of the evolution of opinions as data are accumulated.

Modified high-dose melphalan and autologous SCT for AL amyloidosis or high-risk myeloma: analysis of SWOG trial S0115.
    Bone marrow transplantation, 2013, Volume: 48, Issue:12

    We designed a trial using two sequential cycles of modified high-dose melphalan at 100 mg/m(2) and autologous SCT (mHDM/SCT) in AL amyloidosis (light-chain amyloidosis, AL), AL with myeloma (ALM) and host-based high-risk myeloma (hM) patients through SWOG-0115. The primary objective was to evaluate OS. From 2004 to 2010, 93 eligible patients were enrolled at 17 centers in the United States (59 with AL, 9 with ALM and 25 with hM). The median OS for patients with AL and ALM was 68 months and 47 months, respectively, and has not been reached for patients with hM. The median PFS for patients with AL and ALM was 38 months and 16 months, respectively, and has not been reached for patients with hM. The treatment-related mortality (TRM) was 12% (11/93) and was observed only in patients with AL after SCT. Grade 3 and higher non-hematologic adverse events were experienced by 81%, 67% and 57% of patients with AL, ALM and hM, respectively, during the first and second HDM/SCT. This experience demonstrates that with careful selection of patients and use of mHDM for SCT in patients with AL, ALM and hM, even in the setting of a multicenter study, OS can be improved with acceptable TRM and morbidity.

A randomized phase II trial of fludarabine/melphalan 100 versus fludarabine/melphalan 140 followed by allogeneic hematopoietic stem cell transplantation for patients with multiple myeloma.
    Biology of blood and marrow transplantation : journal of the American Society for Blood and Marrow Transplantation, 2013, Volume: 19, Issue:10

    Allogeneic hematopoietic stem cell transplantation (allo-HCT) is a potentially curative treatment for multiple myeloma (MM); however, because of high treatment-related mortality (TRM), its role is not well defined. Patients with newly diagnosed, relapsed, or primary refractory myeloma were enrolled in a randomized phase II trial of 2 reduced-intensity conditioning regimens: fludarabine 120 mg/m(2) + melphalan 100 mg/m(2) (FM100) versus fludarabine 120 mg/m(2) + melphalan 140 mg/m(2) (FM140) before allo-HCT from related or unrelated donors. Fifty patients underwent allo-HCT using FM100 (n = 23) or FM140 (n = 27) conditioning between April 2002 and 2011. There were no significant differences between FM100 and FM140 in time to neutrophil engraftment (P = .21), acute grade II to IV graft-versus-host disease (GVHD) (P = 1.0), chronic GVHD (P = .24), response rate (P = 1.0), TRM (13% versus 15%, P = 1.0), median progression-free survival (PFS), 11.7 versus 8.4 months, P = .12, and median overall survival (OS), 35.1 versus 19.7 months, P = .38. Cumulative incidence of disease progression in FM100 and FM140 was 43% and 70%, respectively (P = .08). Recurrent disease was the most common cause of death for both FM100 (26%) and FM140 (44%), P = .24. On multivariate analysis, disease status at allo-HCT, complete response or very good partial response (VGPR) was significantly associated with longer PFS (15.6 versus 9.6 months in patients with

Combination of high-dose melphalan and bortezomib as conditioning regimen for autologous peripheral blood stem cell transplantation in multiple myeloma.
    International journal of hematology, 2013, Volume: 98, Issue:3

    Bortezomib and melphalan have synergistic effects against multiple myeloma (MM) cells. We conducted a pilot study on the combination of bortezomib and high-dose melphalan (Bor-HDM) as a conditioning regimen followed by autologous stem cell transplant (ASCT) in 17 Japanese patients with newly diagnosed MM, in comparison with a historical control of patients who received high-dose melphalan (HDM) only followed by ASCT. Nine patients received a single dose of bortezomib 1.3 mg/m(2) on day -1 in combination with melphalan 100 mg/m(2) on days -3 and -2 (Bor1-HDM), and eight received two doses of bortezomib 1.3 mg/m(2) on days -4 and -1 (Bor2-HDM) in combination with HDM. Engraftment of autologous peripheral blood stem cells and regimen-related toxicities (RRT) were comparable among the HDM and Bor-HDM groups. Probability of upgrading from a less than very good partial response (VGPR) to VGPR after ASCT was approximately two times higher in the Bor-HDM group than in the HDM group. However, we observed no significant differences in engraftment, RRT, and response rates between the Bor1-HDM and Bor2-HDM groups. The present study showed that concurrent administration of at least two doses of bortezomib in combination with HDM can be safe in Japanese patients. Additional large prospective randomized trials are required to address the optimal dosages and schedules of bortezomib administration, as well as the efficacy of the Bor-HDM conditioning regimen for ASCT.

A phase I dose-escalation trial of high-dose melphalan with palifermin for cytoprotection followed by autologous stem cell transplantation for patients with multiple myeloma with normal renal function.
    Biology of blood and marrow transplantation : journal of the American Society for Blood and Marrow Transplantation, 2013, Volume: 19, Issue:1

    Melphalan 200 mg/m(2) is the standard conditioning regimen for patients with multiple myeloma (MM) with normal renal function (NRF) undergoing autologous stem cell transplant (ASCT). In an effort to escalate the dose of melphalan and to improve the efficacy, we designed a dose-escalation study of melphalan in conjunction with palifermin in patients with NRF, with the hope that a higher dose of melphalan can be administered with an acceptable degree of oral mucositis (OM). We enrolled 19 patients (18 evaluable) with NRF. Dose-escalation of melphalan administered on day -2 began at 200 mg/m(2) with palifermin administered at a fixed dose of 60 mcg/kg/day. Palifermin was given as an i.v. bolus on day -5, -4, and -3, and then on day +1, +2, and +3. Subsequent dose escalations of melphalan were done at 20 mg/m(2) increments up to a maximum dose of 280 mg/m(2). Of 18 evaluable patients, there were no treatment-related deaths by day 100. The median age was 48.5 years (range, 33-65 years). The most common adverse events related to palifermin included rash (18 events, no ≥ grade 3 events), elevation of amylase (10 events, 4 were grade 3 but asymptomatic), and lipase (5 events, 2 were grade 3 but asymptomatic), edema (11 events, no ≥ grade 3). The overall incidence of OM grade 3 was 44% (8/18) with a median duration of severe mucositis of 5 days (range, 3-6 days). Eleven patients (61%) required opioid analgesics. None of the patients received total parenteral nutrition (TPN)/nasogastric feeding. Two of 6 patients who were given melphalan 280 mg/m(2) did not develop OM. Cardiac dose-limiting toxicity (DLT) in the form of atrial fibrillation did occur in 1 of 6 patients treated with melphalan 280 mg/m(2). Palifermin has permitted safe dose escalation of melphalan up to 280 mg/m(2), thus reaching the cumulative dosage of melphalan administered in tandem ASCT. This higher dose of melphalan has the potential to improve the efficacy and, hopefully, outcomes of patients with MM with a single ASCT. A phase 2 trial is necessary to better delineate the antimyeloma efficacy of this regimen.

Intravenous busulfan and melphalan as a conditioning regimen for autologous stem cell transplantation in patients with newly diagnosed multiple myeloma: a matched comparison to a melphalan-only approach.
    Biology of blood and marrow transplantation : journal of the American Society for Blood and Marrow Transplantation, 2013, Volume: 19, Issue:1

    Melphalan 200 mg/m(2) (MEL200) is the standard conditioning regimen administered to newly diagnosed patients with multiple myeloma (MM) undergoing autologous stem cell transplantation (ASCT). Few alternatives have been explored in order to improve the antimyeloma activity of this conditioning. We compare i.v. busulfan (BU) 9.6 mg/kg and MEL 140 mg/m(2) (MEL140) versus MEL200 mg/m(2) as a conditioning regimen before ASCT for newly diagnosed patients with MM. For this purpose, 51 patients receiving i.v. BU plus MEL were compared to 102 patients receiving MEL200 mg/m(2) in a 1:2 matched control analysis. Matching criteria included age, clinical stage at diagnosis, and response to induction therapy. No differences in the overall and complete response (CR) rates were observed after ASCT between both groups. After a median follow-up of 63 and 50 months in control and BU plus MEL groups, progression-free survival (PFS) was 24 and 33 months, respectively (P = .10). Most frequent toxicities included mucositis and febrile neutropenia in both groups. No case of sinusoidal obstruction syndrome was observed. Transplant-related mortality was 4% and 2% in BU plus MEL and control groups, respectively. ASCT conditioned with i.v. BU plus MEL may be considered an effective and well-tolerated alternative to a MEL-only approach as a conditioning regimen for patients with MM who are candidates for ASCT.

Lenalidomide-prednisone induction followed by lenalidomide-melphalan-prednisone consolidation and lenalidomide-prednisone maintenance in newly diagnosed elderly unfit myeloma patients.
    Leukemia, 2013, Volume: 27, Issue:3

    This multicenter phase II trial evaluated the safety and efficacy of lenalidomide-prednisone (RP) induction, followed by lenalidomide-melphalan-prednisone (MPR) consolidation and RP maintenance in elderly unfit newly diagnosed myeloma patients. Patients received four 28-day RP induction courses (lenalidomide 25 mg/day on days 1-21 and prednisone 50 mg three times/week), followed by six 28-day MPR consolidation cycles (melphalan 2 mg, prednisone 50 mg three times/week and lenalidomide 10-15 mg/day on days 1-21), and maintenance with lenalidomide (10 mg/day on days 1-21 every 28 days) plus prednisone (25 mg three times/week). Forty-six patients were enrolled. Median age was 75 years, 59% of patients had at least one comorbidity and 35% at least two. Partial response rate was 80%, including 29% very good partial response. Median time to progression was 19.6 months, median progression-free survival was 18.4 months and 2-year overall survival was 80%. At the tolerated consolidation dose (melphalan 25 mg/month and lenalidomide 10 mg/day), the most frequent grade 3 adverse events were neutropenia (36.4%), anemia (12.1%), cutaneous reactions (18.2%) and infections (12.1%). Grade 4 neutropenia occurred in 12.1% of patients. In conclusion, RP induction followed by MPR consolidation and RP maintenance showed a manageable safety profile, and reduced the risk of severe hematological toxicity in unfit elderly myeloma patients.

Bortezomib, melphalan, and prednisone in elderly patients with relapsed/refractory multiple myeloma: a multicenter, open label phase 1/2 study.
    Cancer, 2013, Mar-01, Volume: 119, Issue:5

    In elderly patients with newly diagnosed multiple myeloma (MM), the addition of bortezomib to standard, combined oral melphalan and prednisone (MP) significantly increases the response rate and event-free survival compared with MP alone.. In this phase 1/2 trial, the authors assessed the dosing, efficacy, and safety of a lower dose-intensity MP schedule plus weekly bortezomib as salvage treatment for elderly patients with MM. To assess the maximum tolerated dose, 19 patients who had relapsed/refractory MM after 1 or 2 lines of treatment entered the first phase of the study. They received melphalan at a dose of 24 mg for 28 days; bortezomib 1.3 mg/m(2) on days 1, 8, 15, and 22; and prednisone at a dose of 50 mg every other day of a 28-day cycle for a total of 9 cycles. At the end of the first phase, based on the good efficacy and acceptable toxicity of this combination, an additional 23 patients were enrolled.. After a median follow-up of 21 months, of 42 patients who relapsed, 24 (57%) obtained at least a partial response, 4 had stable disease, and 11 had progressive disease. The median time to progression was 18 months, and the median overall survival was 30 months. Grade 3 and 4 toxicity was observed in 16 of 42 patients (38%) and was more frequent during the early cycles.. A weekly infusion of bortezomib associated with lower dose-intensity MP induced a high proportion of responses and was well tolerated in elderly patients with relapsed/refractory MM.

Lenalidomide plus melphalan without prednisone for previously untreated older patients with multiple myeloma: a phase II trial.
    Clinical lymphoma, myeloma & leukemia, 2013, Volume: 13, Issue:1

    We conducted a phase II trial that evaluated the tolerability and efficacy of combining lenalidomide with melphalan in previously untreated patients with multiple myeloma who were not candidates for autologous stem cell transplantation.. After a run-in phase of 6 patients, we planned to conduct a randomized phase II selection-design trial that assessed 2 dose levels of lenalidomide, given days 1 to 21, combined with melphalan, given days 1 to 4, and every 28 days. Planned doses of melphalan were 9 mg/m(2)/d and respective doses of lenalidomide were 10 and 20 mg/d (M9L10 and M9L20). Coprimary endpoints were the frequency of dose-limiting Planned doses of melphalan were 9 mg/m(2)/d and respective doses of lenalidomide were 10 and 20 mg/d (M9L10 and M9L20). toxicities (DLT) and complete response (CR).. Four patients received M9L10; all experienced DLTs, which resulted in closure of this cohort. When using the same schedule, we then sequentially tested M6L10 (melphalan 6 mg/m(2) on days 1 to 4 and lenalidomide 10 mg/d on days 1 to 21 every 28 days) (6 patients), M4L15 (melphalan 4 mg/m(2) on days 1 to 4 and lenalidomide 15 mg/d on days 1 to 21 every 28 days) (6 patients), and M5L10 (melphalan 5 mg/m(2) days 1 to 4 and lenalidomide 10 mg/d days 1 to 21 every 28 days) (34 patients). In each cohort, the DLT endpoint was reached because of severe and prolonged hematologic toxicity. At the final dose level, M5L10, 20 of 27 patients experienced DLTs within their first 3 cycles; among 10 patients who received at least 6 cycles, none achieved a CR.. Combining lenalidomide plus melphalan without prednisone is associated with substantial hematologic toxicity that precludes cyclical administration of adequate drug doses.

Persistent overall survival benefit and no increased risk of second malignancies with bortezomib-melphalan-prednisone versus melphalan-prednisone in patients with previously untreated multiple myeloma.
    Journal of clinical oncology : official journal of the American Society of Clinical Oncology, 2013, Feb-01, Volume: 31, Issue:4

    This final analysis of the phase III VISTA trial (Velcade As Initial Standard Therapy in Multiple Myeloma: Assessment With Melphalan and Prednisone) was conducted to determine whether the overall survival (OS) benefit with bortezomib-melphalan-prednisone (VMP) versus melphalan-prednisone (MP) in patients with myeloma who were ineligible for transplantation was maintained after 5 years of follow-up and to explore the risk of second primary malignancies.. In all, 682 patients received up to nine 6-week cycles of VMP or MP and were then observed every 12 weeks or less. Data on second primary malignancies were collected by individual patient inquiries at all sites from 655 patients.. After median follow-up of 60.1 months (range, 0 to 74 months), there was a 31% reduced risk of death with VMP versus MP (hazard ratio [HR], 0.695; P < .001; median OS 56.4 v 43.1 months). OS benefit with VMP was seen across prespecified patient subgroups (age ≥ 75 years, stage III myeloma, creatinine clearance < 60 mL/min). Sixty-three percent of VMP patients and 73% of MP patients had received subsequent therapy. Time to next therapy (median, 30.7 v 20.5 months; HR, 0.557; P < .001) was longer with VMP than with MP. Among patients who received subsequent therapies, survival from start of subsequent therapy was similar following VMP (median, 28.1 months) or MP (median, 26.8 months; HR, 0.914). Following VMP/MP, incidence proportions of hematologic malignancies (1%/1%) and solid tumors (5%/3%) and exposure-adjusted incidence rates (0.017/0.013 per patient-year) were similar and were consistent with background rates.. VMP resulted in a significant reduction in risk of death versus MP that was maintained after 5 years' follow-up and despite substantial use of novel-agent-based salvage therapies. There is no emerging safety signal for second primary malignancies following VMP.

    This randomized-controlled trial studied the efficacy of palifermin in a chemotherapy-only, high-dose Melphalan (HDM) transplant setting, to reduce oral mucositis (OM) and its sequelae measured by patient-reported outcomes (PRO) and medical resource use. Palifermin, relative to placebo was given either pre-/post-HDM or pre-HDM in patients with multiple myeloma (MM) undergoing auto-SCT at 39 European centers. Oral cavity assessment (WHO) and PRO questionnaires (oral mucositis daily questionnaire (OMDQ) and EQ 5D) were used in 281 patients (mean age 56, ± s.d.=8 years). 57 patients received placebo. One hundred and fifteen subjects were randomized to pre-/post-HDM receiving palifermin on 3 consecutive days before HDM and after auto-SCT and 109 patients were randomized to pre-HDM, receiving palifermin (60 μg/kg/day) i.v. for 3 consecutive days before HDM. There was no statistically significant difference in maximum OM severity. Severe OM occurred in 37% (placebo), 38% (pre-/post-HDM) and 24% (pre-HDM) of patients. No significant difference was observed with respect to PRO assessments or medical resource use, but more infections and fever during neutropenia were reported in pre-/post-HDM vs placebo (for example, 51 and 26%). To conclude, palifermin was unable to reduce OM or OM-related patient's burden in MM transplant patients.

Lenalidomide, melphalan, and prednisone, followed by lenalidomide maintenance, improves health-related quality of life in newly diagnosed multiple myeloma patients aged 65 years or older: results of a randomized phase III trial.
    Haematologica, 2013, Volume: 98, Issue:5

    The MM-015 trial assessed the effect of lenalidomide-based therapy on health-related quality of life. Patients (n=459) with newly diagnosed multiple myeloma aged 65 years or over were randomized 1:1:1 to nine 4-week cycles of lenalidomide, melphalan, and prednisone, followed by lenalidomide maintenance; or lenalidomide, melphalan, and prednisone, or melphalan and prednisone, with no maintenance therapy. Patients completed health-related quality of life questionnaires at baseline, after every third treatment cycle, and at treatment end. Health-related quality of life improved in all treatment groups during induction therapy. Patients receiving lenalidomide maintenance had the most pronounced improvements, Global Health Status/Quality of Life (P<0.05), Physical Functioning (P<0.01), and Side Effects of Treatment (P<0.05) out of 6 pre-selected health-related quality of life domains. More patients receiving lenalidomide maintenance achieved minimal important differences (P<0.05 for Physical Functioning). Therefore, lenalidomide, melphalan, and prednisone, followed by lenalidomide maintenance, improves health-related quality of life in patients with newly diagnosed multiple myeloma.

A phase II open-label trial of bortezomib in patients with multiple myeloma who have undergone an autologous peripheral blood stem cell transplant and failed to achieve a complete response.
    Investigational new drugs, 2012, Volume: 30, Issue:2

    A majority of multiple myeloma (MM) patients fail to achieve complete response (CR) to peripheral blood stem cell transplantation (PBSCT); effective options following autologous transplantation are needed. Bortezomib (B) is active against MM. This study was conducted to determine the feasibility, safety, tolerability, and efficacy of B following high-dose melphalan therapy and PBSCT. Methods Fifty patients enrolled (48 evaluable) and 49 were treated (safety population).. 4 cycles B 1.3 mg/m(2) Days 1, 4, 8, and 11/21-days; 4 additional cycles were permitted for stable or responding patients. Results Median age was 55 years (range, 38-73), 68% male, 64% ECOG PS = 0, 44% Durie-Salmon Stage IIIA prior to induction, 42% had symptomatic IgG MM; 74% had prior single transplant (26% tandem). Responses post-transplant: 70% PRs, 18% MRs. A median of 4 cycles (range, 2-8) of B were administered. Responses: CR 8%, uCR 2%, PR 23%, uPR 19%, MR 10%, and no change 35%; median time-to-treatment failure (TTF) was 6.2 months (range, 1.0-19.4). Three deaths occurred (n = 1 sepsis, n = 2 disease progression). Grade 3-4 treatment-related toxicities included: thrombocytopenia, neuropathy (14%, each); asthenia, neutropenia (10%, each); and nausea (4%). Twelve patients (24%) discontinued treatment due to toxicity and 30 patients (60%) completed the study; 20 patients started new treatment (median 5.8 months [range, 1.5-20.3]).. The study closed early due to widespread availability of B, and the lack of B-naïve patients. Bortezomib monotherapy after melphalan and autologous PBSCT was feasible, safe and well-tolerated (toxicities were manageable), but failed to produce the hypothesized response rates.

Tandem chemo-mobilization followed by high-dose melphalan and carmustine with single autologous hematopoietic cell transplantation for multiple myeloma.
    Bone marrow transplantation, 2012, Volume: 47, Issue:4

    Single autologous hematopoietic cell transplant (AHCT) with high-dose melphalan prolongs survival in patients with multiple myeloma but is not curative. We conducted a study of intensive single AHCT using tandem chemo-mobilization with CY and etoposide followed by high-dose conditioning with melphalan 200 mg/m(2) plus carmustine 15 mg/kg. One hundred and eighteen patients in first consolidation (CON1) and 58 patients in relapse (REL) were transplanted using this intensified approach. Disease response improved from 32% very good PR (VGPR)+CR pre-mobilization to 76% VGPR+CR post transplant in CON1. With a median follow-up of 4.7 years, the median EFS was 2.8 years, and the median OS was 5.1 years in CON1. OS from time of transplant was significantly shorter for REL (3.4 years) compared with CON1 (5.1 years; P=0.02). However, OS from time of diagnosis was similar in REL (6.1 years) and CON1 (6.0 years; P=0.80). The 100-day non-relapse mortality in the CON1 and REL groups was 0% and 7%, respectively. In summary, intensified single AHCT with tandem chemo-mobilization and augmented high-dose therapy is feasible in multiple myeloma and leads to high-quality response rates.

A randomized phase 2 trial of a preparative regimen of bortezomib, high-dose melphalan, arsenic trioxide, and ascorbic acid.
    Cancer, 2012, May-01, Volume: 118, Issue:9

    Bortezomib is active for newly diagnosed and relapsed multiple myeloma, and it has synergistic activity with melphalan. The authors of this report conducted a randomized trial to determine the safety and efficacy of adding bortezomib to a preparative regimen of arsenic trioxide (ATO), ascorbic acid (AA), and melphalan.. Among 60 patients who enrolled between October 2006 and September 2007, 58 patients underwent autologous transplantation with a preparative regimen of melphalan 200 mg/m(2) intravenously, AA 1000 mg daily intravenously for 7 days, and ATO 0.25 mg/kg intravenously for 7 days. Patients were randomized to receive no bortezomib (Group 1), bortezomib 1 mg/m(2) × 3 doses (Group 2), and bortezomib 1.5 mg/m(2) × 3 doses (Group 3). Primary endpoints were complete response (CR), grade IV toxicity, and 90-day treatment-related mortality (TRM). Secondary endpoints were progression-free survival (PFS) and overall survival (OS).. The median follow-up of all surviving patients was 36 months (range, 20-43 months). The CR rates in Groups 1, 2, and 3 were 20%, 10%, and 10%, respectively. Grade 3 and 4 nonhematologic toxicities and TRM were comparable. The median OS was not reached in the groups, whereas the median PFS in Groups 1, 2, and 3 was 17.8 months, 17.4 months, and 20.7 months, respectively. PFS and OS were significantly shorter in patients who had high-risk cytogenetics (P = .016 and P = .0001, respectively) and relapsed disease (P = .0001 and P = .0001, respectively) regardless of the treatment group.. Adding bortezomib to a preparative regimen of ATO, AA, and high-dose melphalan was safe and well tolerated in patients with multiple myeloma. There was no significant improvement in the CR rate, PFS, or OS in the bortezomib groups.

Phase II study of melphalan, thalidomide and prednisone combined with oral panobinostat in patients with relapsed/refractory multiple myeloma.
    Leukemia & lymphoma, 2012, Volume: 53, Issue:9

    The combination of melphalan, prednisone and thalidomide (MPT) has demonstrated efficacy and acceptable toxicity in newly diagnosed and relapsed/refractory patients with multiple myeloma (MM). Panobinostat is a potent oral pan-deacetylase inhibitor (pan-DACi). In preclinical and clinical studies, panobinostat showed good anti-myeloma activity in combination with several agents. This phase II study evaluated the combination of a fixed dose of MPT with escalating doses of panobinostat (three times weekly for 3 weeks, followed by a 9-day rest period) in relapsed/refractory MM. We used a two-stage design to determine whether the combination was safe and effective. At least a partial response was observed in 38.5% of patients. The maximum tolerated dose of panobinostat in combination with MPT could not be determined due to the high rate of dose-limiting toxicities experienced with panobinostat at doses of 10 and 15 mg. The most common grade 3/4 adverse events were neutropenia (71%) and thrombocytopenia (35.5%). In conclusion, MPT in combination with panobinostat three times weekly for 3 weeks followed by a 9-day rest period is not well tolerated in patients with relapsed/refractory MM. Future studies should evaluate alternative dose schedules of panobinostat.

Thalidomide and dexamethasone vs. bortezomib and dexamethasone for melphalan refractory myeloma: a randomized study.
    European journal of haematology, 2012, Volume: 88, Issue:6

    Thalidomide and bortezomib have been frequently used for second-line therapy in patients with myeloma relapsing after or refractory to initial melphalan-based treatment, but no randomized trials have been published comparing these two treatment alternatives.. Thalidomide- and bortezomib-naïve patients with melphalan refractory myeloma were randomly assigned to low-dose thalidomide + dexamethasone (Thal-Dex) or bortezomib + dexamethasone (Bort-Dex). At progression on either therapy, the patients were offered crossover to the alternative drug combination. An estimated 300 patients would be needed for the trial to detect a 50% difference in median PFS between the treatment arms.. After inclusion of 131 patients, the trial was prematurely closed because of low accrual. Sixty-seven patients were randomized to Thal-Dex and 64 to Bort-Dex. Progression-free survival was similar (median, 9.0 months for Thal-Dex and 7.2 for Bort-Dex). Response rate was similar (55% for Thal-Dex and 63% for Bort-Dex), but time to response was shorter (P < 0.05) and the VGPR rate higher (P < 0.01) for Bort-Dex. Time-to-other treatment after crossover was similar (median, 13.2 months for Thal-Dex and 11.2 months for Bort-Dex), as was overall survival (22.8 months for Thal-Dex and 19.0 for Bort-Dex). Venous thromboembolism was seen in seven patients and cerebrovascular events in four patients in the Thal-Dex group. Severe neuropathy, reactivation of herpes virus infections, and mental depression were more frequently observed in the Bort-Dex group. In the quality-of-life analysis, no difference was noted for physical function, pain, and global quality of life. Fatigue and sleep disturbances were significantly more prevalent in the Bort-Dex group.. Thalidomide (50-100 mg daily) in combination with dexamethasone seems to have an efficacy comparable with that of bortezomib and dexamethasone in melphalan refractory myeloma. However, the statistical strength of the results in this study is limited by the low number of included patients.

Bortezomib salvage followed by a Phase I/II study of bortezomib plus high-dose melphalan and tandem autologous transplantation for patients with primary resistant myeloma.
    British journal of haematology, 2012, Volume: 157, Issue:5

    We conducted a Phase 1/2 study of bortezomib administered in combination with high-dose melphalan followed by tandem autologous transplants in patients with primary resistant multiple myeloma. Thirty patients received two cycles of salvage bortezomib followed by stem cell mobilization with granulocyte colony-stimulating factor and harvest. Melphalan 100 mg/m(2) per day on two consecutive days was administered, immediately followed by one dose of bortezomib (dose escalation) and stem cell infusion. The median beta 2-microglobulin was 4·35 mg/l (range: 1·8-11·4); albumin was 37 g/l (range: 3·1-4·9); high-risk karyotypes were noted in 45% of patients. The maximum planned dose of bortezomib at 1·3 mg/m(2) was well tolerated and a formal maximum tolerated dose was not determined. The peak of best overall response (≥partial response) and complete response rates after tandem transplants were 84% and 36%, respectively. With a median follow-up of 48 months, the median progression-free survival was 15 [95% confidence interval (CI): 11-21] months and the median overall survival was 35 (95% CI: 22-43) months. Correlative studies demonstrated decreased expression of BRCA2 (P = 0·0072) and FANCF (P = 0·0458) mRNA following bortezomib treatment. Bortezomib combined with high-dose melphalan is a well-tolerated conditioning with some activity in patients with resistant myeloma.

Melphalan 180 mg/m2 can be safely administered as conditioning regimen before an autologous stem cell transplantation (ASCT) in multiple myeloma patients with creatinine clearance 60 mL/min/1.73 m2 or lower with use of palifermin for cytoprotection: resul
    Biology of blood and marrow transplantation : journal of the American Society for Blood and Marrow Transplantation, 2012, Volume: 18, Issue:9

    High-dose melphalan 140 mg/m2 is the standard of care for patients with multiple myeloma (MM) with renal insufficiency (RI). Palifermin as a cytoprotective agent has demonstrated efficacy in reducing the intensity and duration of oral mucositis (OM) in patients who receive intensive chemotherapy/radiotherapy. There is no prospective data on the use of palifermin in patients with MM with RI.. creatinine clearance ≤60 mL/minute/1.73 m2, age >18 years, no dialysis, no active OM, and a suitable candidate for autologous stem cell transplant (ASCT). Melphalan dose ranged from 140 to 200 mg/m2 and escalated at the increment of 20 mg/m2. Six dosages of palifermin 60 mcg/kg/day were given intravenously between day -5 to day +3. Dose escalations were to stop if dose-limiting toxicities (DLTs) occurred at melphalan dose in ≥2 of 3 patients, with that dose declared as the maximal administered dose and the level below where ≤1 of 6 patients had DLTs was considered the maximally tolerated dose (MTD). Nineteen patients were enrolled from June 2007 to June 2011. Data on 15 evaluable patients is reported as 4 patients were removed. Median age was 59 years (range, 36-67 years). The overall incidence of OM ≥ grade 3 was 53% (8 of 15) and a median duration of ≥grade 3 OM was 6.5 days (range, 3-42 days). One patient in L2 (melphalan 160 mg/m2) developed atrial fibrillation on day +9. Two patients in L4 (melphalan 200 mg/m2) developed grade 4 OM, hence reaching DLT. No DLT was observed in 6 patients enrolled in L3 (melphalan 180 mg/m2). Palifermin has permitted safe dose escalation of melphalan up to 180 mg/m(2) in patients with RI.

Health-related quality of life in elderly, newly diagnosed multiple myeloma patients treated with VMP vs. MP: results from the VISTA trial.
    European journal of haematology, 2012, Volume: 89, Issue:1

    The phase 3 VISTA study (ClinicalTrials.gov NCT00111319) in transplant-ineligible myeloma patients demonstrated superior efficacy with bortezomib-melphalan-prednisone (VMP; nine 6-wk cycles) vs. melphalan-prednisone (MP) but also increased toxicity. Health-related quality of life (HRQoL; exploratory endpoint) was evaluated using the European Organization for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire (QLQ-C30). The phase 3 VISTA study (ClinicalTrials.gov NCT00111319) in transplant-ineligible myeloma patients demonstrated superior efficacy with bortezomib-melphalan-prednisone (VMP; nine 6-wk cycles) vs. melphalan-prednisone (MP) but also increased toxicity. Health-related quality of life (HRQoL; exploratory endpoint) was evaluated using the European Organization for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire (QLQ-C30).. EORTC QLQ-C30 was administered at screening, on day 1 of each cycle, at the end-of-treatment visit, and every 8 wk until progression. EORTC QLQ-C30 scores were evaluated among patients with a valid baseline and at least one post-baseline HRQoL assessment.. At baseline, domain scores were similar between arms. By cycle 4, mean differences were clinically meaningful for most domains, indicating poorer health status with VMP. From cycle 5 onwards, improvements relative to baseline/MP were observed for all domains with VMP. Mean scores were generally improved by the end-of-treatment assessment vs. baseline in both arms. Among responding patients, mean scores generally improved from time of response to end-of-treatment assessment, substantially driven by patients achieving complete response (CR). Multivariate analysis showed a significant impact of duration of response/CR on improving global health status, pain, and appetite loss scores. Analyses by bortezomib dose intensity indicated better HRQoL in patients receiving lower dose intensity.. These findings demonstrate clinically meaningful, transitory HRQoL decrements with VMP and relatively lower HRQoL vs. MP during early treatment cycles, associated with the expected additional toxicities. However, HRQoL is not compromised in the long term, recovering by the end-of-treatment visit to be comparable vs. MP.

Effect of time to infusion of autologous stem cells (24 vs. 48 h) after high-dose melphalan in patients with multiple myeloma.
    European journal of haematology, 2012, Volume: 89, Issue:2

    High-dose melphalan (HD-Mel) is considered the current standard of care among the preparative regimens used in autologous peripheral blood stem cell transplantation (SCT) for multiple myeloma (MM), but optimal time and schedule of administration is not defined. We retrospectively analyzed outcomes and toxicities of HD-Mel administered on day -2 vs. day -1 before autologous stem cells infusion. A total of 138 consecutive MM patients treated at Penn State Hershey Cancer Institute between 2007 and 2010 were included in this study. No difference in time to hematopoietic recovery, common SCT-related toxicities, and clinical outcomes was seen between patients who received HD-Mel on day -2 (group A, n = 47), and those who received it on day -1 (group B, n = 91). Prompt and full hematopoietic recovery occurred even when stem cells were infused between 8 and 24 h after completion of chemotherapy. In the absence of prospective and randomized data, we conclude that a single I.V. infusion of HD-Mel on day -1 is a safe and effective practice, and the so-called 'day of rest' before the transplant appears not to be necessary.

Continuous lenalidomide treatment for newly diagnosed multiple myeloma.
    The New England journal of medicine, 2012, May-10, Volume: 366, Issue:19

    Lenalidomide has tumoricidal and immunomodulatory activity against multiple myeloma. This double-blind, multicenter, randomized study compared melphalan-prednisone-lenalidomide induction followed by lenalidomide maintenance (MPR-R) with melphalan-prednisone-lenalidomide (MPR) or melphalan-prednisone (MP) followed by placebo in patients 65 years of age or older with newly diagnosed multiple myeloma.. We randomly assigned patients who were ineligible for transplantation to receive MPR-R (nine 4-week cycles of MPR followed by lenalidomide maintenance therapy until a relapse or disease progression occurred [152 patients]) or to receive MPR (153 patients) or MP (154 patients) without maintenance therapy. The primary end point was progression-free survival.. The median follow-up period was 30 months. The median progression-free survival was significantly longer with MPR-R (31 months) than with MPR (14 months; hazard ratio, 0.49; P<0.001) or MP (13 months; hazard ratio, 0.40; P<0.001). Response rates were superior with MPR-R and MPR (77% and 68%, respectively, vs. 50% with MP; P<0.001 and P=0.002, respectively, for the comparison with MP). The progression-free survival benefit associated with MPR-R was noted in patients 65 to 75 years of age but not in those older than 75 years of age (P=0.001 for treatment-by-age interaction). After induction therapy, a landmark analysis showed a 66% reduction in the rate of progression with MPR-R (hazard ratio for the comparison with MPR, 0.34; P<0.001) that was age-independent. During induction therapy, the most frequent adverse events were hematologic; grade 4 neutropenia was reported in 35%, 32%, and 8% of the patients in the MPR-R, MPR, and MP groups, respectively. The 3-year rate of second primary tumors was 7% with MPR-R, 7% with MPR, and 3% with MP.. MPR-R significantly prolonged progression-free survival in patients with newly diagnosed multiple myeloma who were ineligible for transplantation, with the greatest benefit observed in patients 65 to 75 years of age.

Thalidomide plus dexamethasone as a maintenance therapy after autologous hematopoietic stem cell transplantation improves progression-free survival in multiple myeloma.
    American journal of hematology, 2012, Volume: 87, Issue:10

    Despite the good response of stem cell transplant (SCT) in the treatment of multiple myeloma (MM), most patients relapse or do not achieve complete remission, suggesting that additional treatment is needed. We assessed the impact of thalidomide in maintenance after SCT in untreated patients with MM. A hundred and eight patients (<70 years old) were randomized to receive maintenance with dexamethasone (arm A; n = 52) or dexamethasone with thalidomide (arm B; n = 56; 200 mg daily) for 12 months or until disease progression. After a median follow-up of 27 months, an intention to treat analysis showed a 2-year progression-free survival (PFS) of 30% in arm A (95% CI 22-38) and 64% in arm B (95% CI 57-71; P = 0.002), with median PFS of 19 months and 36 months, respectively. In patients who did not achieve at least a very good partial response, the PFS at 2 years was significantly higher when in use of thalidomide (19 vs. 59%; P = 0.002). Overall survival at 2 years was not significantly improved (70 vs. 85% in arm A and arm B, respectively; P = 0.27). The addition of thalidomide to dexamethasone as maintenance improved the PFS mainly in patients who did not respond to treatment after SCT.

Phase I trial of bortezomib during maintenance phase after high dose melphalan and autologous stem cell transplantation in patients with multiple myeloma.
    Journal of chemotherapy (Florence, Italy), 2012, Volume: 24, Issue:3

    We enrolled 15 patients in this phase I dose de-escalation trial. Twelve patients are evaluable. The primary objective was to determine the safest and best tolerated maintenance dosing (MD) of bortezomib (B). The secondary endpoints were to evaluate complete response (CR), overall response (OR) and response duration. All patients receiving autologous stem cell transplant (ASCT) were eligible and registered between D+30 to D+120 after ASCT. A maximum number of 8 cycles of B was planned. Two evaluable patients in level (L) 1 received therapeutic dose of B 1.3 mg/m(2) intravenously on days (D) 1, 4, 8, and 11 in a 21 day cycle. Both these patients experienced dose limiting toxicities (DLTs). Four evaluable patients were then enrolled in dose L2 utilizing B 1.3 mg/m(2) on D 1, 4, 8, and 11 in a 28 day cycle. Two patients in L2 developed DLTs. Six evaluable patients were thereafter enrolled in L3 utilizing B 1 mg/m(2) on D 1, 8, and 15 in a 28 day cycle. Median 8 cycles of B were administered (2-8). No DLTs were observed in L3. The median duration of follow up for the entire cohort is 33 months (12-62). The median duration of response in L3 is 29.1 months (12-33). We conclude that B 1 mg/m(2) administered intravenously and may be subcutaneously on D 1, 8, and 15 in a 28 day cycle is the best tolerated MD and can be safely given beginning around D+100 post-ASCT.

Phase II trial of high-dose topotecan, melphalan and CY with autologous stem cell support for multiple myeloma.
    Bone marrow transplantation, 2011, Volume: 46, Issue:4

    In spite of high-dose chemotherapy followed by autologous hematopoietic SCT multiple myeloma (MM) eventually recurs, highlighting the need for more effective treatment approaches. Patients received topotecan 3.5 mg/m(2) intravenously on days -6 to -2, melphalan 70 mg/m(2) intravenously on days -3 and -2 and CY 1 g/m(2) intravenously on days -6, -5 and -4. Overall response rate (ORR) consisting of complete response and partial response (CR+PR, PFS, OS and toxicity are reported. Between August 2002 to March 2004, 60 patients (34 men and 26 women) with a median age of 61 years (range 45-72) were enrolled. Forty-one patients were treated for consolidation of first remission, while 19 patients had relapsed/refractory disease. ORR was 85% (CR 12%, very good PR 43% and PR 30%). Median time to neutrophil (ANC>0.5 × 10(9)/L) and plt engraftment (>20 × 10(9)/L) was 10 (range 7-12 days) and 9 days (range 6-79 days), respectively. A majority of the common adverse events were grade 1-3 mucositis/stomatitis (65%), grade 1 or 2 nausea (59%) and grade 1 or 2 diarrhea (41%). Median PFS was 18.5 months and median OS has yet not been reached. In conclusion, topotecan, melphalan and CY is a safe and active conditioning regimen for auto hematopoietic SCT in MM. The ORR and PFS were comparable to high-dose melphalan.

Intravenous busulfan plus melphalan is a highly effective, well-tolerated preparative regimen for autologous stem cell transplantation in patients with advanced lymphoid malignancies.
    Biology of blood and marrow transplantation : journal of the American Society for Blood and Marrow Transplantation, 2011, Volume: 17, Issue:3

    We investigated the administration of intravenous (i.v.) busulfan (Bu) combined with melphalan (Mel) in patients with advanced lymphoid malignancies undergoing autologous stem cell transplantation. Bu 130 mg/m(2) was infused daily for 4 days, either as a fixed dose per body surface area (BSA), or to target an average daily area under the curve of 5000 μmol-min, determined by a test dose of i.v. Bu at 32 mg/m(2) given 48 hours prior to the high-dose regimen, followed by a rest day, followed by 2 daily doses of Mel at 70 mg/m(2). Stem cells were infused the following day. Eighty patients had i.v. Bu delivered per test dose guidance. The median daily systemic Bu exposure was 4867 μmol-min. One hundred two patients (Hodgkin lymphoma n = 49, non-Hodgkin lymphoma n = 12, multiple myeloma = 41) with a median age of 44 years (range: 19-65 years) were treated. The 2-year overall survival and progression-free survival rates were 85% and 57%, respectively, for patients with Hodgkin lymphoma, 67% and 64%, respectively, for patients with non-Hodgkin lymphoma, and 82% and 42%, respectively, for patients with multiple myeloma. The regimen was very well tolerated with treatment-related mortality at 100 days, 1 year, and 2 years of 1%, 3%, and 3%, respectively. Intravenous Bu-Mel was well tolerated. Disease control wa encouraging, and should be explored in larger phase II studies.

Risk factors for, and reversibility of, peripheral neuropathy associated with bortezomib-melphalan-prednisone in newly diagnosed patients with multiple myeloma: subanalysis of the phase 3 VISTA study.
    European journal of haematology, 2011, Volume: 86, Issue:1

    This subanalysis of the phase 3 VISTA trial aimed to assess the frequency, characteristics and reversibility of, and prognostic factors for, bortezomib-associated peripheral neuropathy (PN) in newly diagnosed patients with multiple myeloma ineligible for high-dose therapy who received bortezomib plus melphalan-prednisone.. Patients received nine 6-wk cycles of VMP (bortezomib 1.3 mg/m(2), days 1, 4, 8, 11, 22, 25, 29, 32, cycles 1-4, and days 1, 8, 22, 29, cycles 5-9; melphalan 9 mg/m(2), days 1-4, cycles 1-9; and prednisone 60 mg/m(2), days 1-4, cycles 1-9).. Overall, 47% of patients receiving VMP developed PN, including 19% grade 2 and 13% grade ≥ 3 (<1% grade 4). The PN incidence was dose-related and reached a plateau at a cumulative bortezomib dose of approximately 45 mg/m(2). Median time to PN onset was 2.3 months. Bortezomib-associated PN was reversible; 79% of events improved by at least one NCI CTCAE grade within a median of 1.9 months and 60% completely resolved within a median of 5.7 months, with reversibility similar in responding and non-responding patients. By multivariate analysis, baseline neuropathy was the only consistent risk factor for any PN [hazard ratio (HR) 1.785, P=0.0065], grade ≥ 2 PN (HR 2.205, P=0.0032), and grade ≥ 3 PN (HR 2.438, P=0.023); age, pre-existing diabetes, International Staging System stage, obesity, and creatinine clearance did not affect the overall rate of PN.. Rates of bortezomib-induced PN in the frontline setting were similar to those in relapsed patients and resolved in most cases.

Plerixafor and granulocyte-colony-stimulating factor (G-CSF) in patients with lymphoma and multiple myeloma previously failing mobilization with G-CSF with or without chemotherapy for autologous hematopoietic stem cell mobilization: the Austrian experienc
    Transfusion, 2011, Volume: 51, Issue:5

    Plerixafor in combination with granulocyte-colony-stimulating factor (G-CSF) has been shown to enhance stem cell mobilization in patients with multiple myeloma, non-Hodgkin's lymphoma, and Hodgkin's disease who demonstrated with previous mobilization failure. In this named patient program we report the Austrian experience in insufficiently mobilizing patients.. Twenty-seven patients from eight Austrian centers with a median (range) age of 58 (19-70) years (18 female, nine male) were included in the study. Plerixafor was limited to patients with previous stem cell mobilization failure and was given in the evening of Day 4 of G-CSF application.. A median increase of circulating CD34+ cells within 10 to 11 hours from administration of plerixafor by a factor of 4.7 over baseline was noted. Overall, 20 (74%) patients reached more than 10 × 10(6) CD34+ cells/L in the peripheral blood, resulting in 17 (63%) patients collecting at least 2 × 10(6) CD34+ cells/kg body weight (b.w.; median, 2.6 × 10(6) CD34+ cells/kg b.w.; range, 0.08 × 10(6) -8.07 × 10(6) ). Adverse events of plerixafor were mild to moderate and consisted of gastrointestinal side effects and local reactions at the injection site. Thirteen (48%) patients underwent autologous transplantation receiving a median of 2.93 × 10(6) CD34+ cells/kg (range, 1.46 × 10(6) -5.6 × 10(6) ) and showed a trilinear engraftment with a median neutrophil recovery on Day 12 and a platelet recovery on Day 14.. Our study confirms previous investigations showing that plerixafor in combination with G-CSF is an effective and well-tolerated mobilization regimen with the potential of successful stem cell collection in patients with previous mobilization failure.

Three palonosetron regimens to prevent CINV in myeloma patients receiving multiple-day high-dose melphalan and hematopoietic stem cell transplantation.
    Annals of oncology : official journal of the European Society for Medical Oncology, 2011, Volume: 22, Issue:4

    Explore safety and efficacy of three palonosetron-containing regimens for emesis prevention over 7 days in multiple myeloma (MM) patients receiving melphalan (100 mg/m(2)) and hematopoietic stem cell transplantation (HSCT).. Randomized, double-blind pilot study in MM patients (n=73) receiving 1, 2, or 3 days of 0.25 mg palonosetron (30-s i.v. bolus) 30 min before melphalan (days -2 and -1) and HSCT (day 0). Patients received dexamethasone (20 mg i.v., days -2 and -1) immediately before or after study drug/placebo. Daily diaries recorded emesis, rescue medication, nausea duration, and adverse events (AEs).. Seven-day complete protection (no emesis) occurred in 41.7% [95% confidence interval (CI) 22.1% to 63.4%], 41.7% (95% CI 22.1% to 63.4%), and 44.0% (95% CI 24.2% to 65.1%) of patients receiving 1, 2, or 3 days of palonosetron, respectively (P=0.43). Complete response (emesis free without rescue medication) occurred in 8.3%, 20.8%, and 20.0% (P=0.14). Common AEs (≥10%) were mild-to-moderate diarrhea, constipation, headache, insomnia, and flatulence. No serious AEs occurred.. Palonosetron with dexamethasone was safe and effective in preventing emesis in MM patients receiving melphalan and HSCT. This pilot study with a limited number of patients suggests that multiple doses of palonosetron could be more effective than a single dose in making patients emesis free without need for rescue medication. However, even multiple doses of palonosetron resulted in only 20% of patients being emesis free without rescue medication, suggesting that further improvement will require development of more effective combination antiemetic therapy.

Addition of thalidomide to oral melphalan/prednisone in patients with multiple myeloma not eligible for transplantation: results of a randomized trial from the Turkish Myeloma Study Group.
    European journal of haematology, 2011, Volume: 86, Issue:1

    The combination of melphalan-prednisone-thalidomide (MPT) has been investigated in several clinical studies that differed significantly with regard to patient characteristics and treatment schedules. This prospective trial differs from previous melphalan-prednisone (MP) vs. MPT trials by treatment dosing, duration, routine anticoagulation, and permission for a crossover. Newly diagnosed patients with multiple myeloma (MM) (n=122) aged greater than 55 yr, not eligible for transplantation were randomized to receive 8 cycles of M (9 mg/m(2) /d) and P (60 mg/m(2) /d) for 4d every 6 wk (n=62) or MP and thalidomide (100 mg/d) continuously (n=60). Primary endpoint was treatment response and toxicities following 4 and 8 cycles of therapy. Secondary endpoints were disease-free (DFS) and overall survival (OS). Overall, MPT-treated patients were younger (median 69 yr vs. 72 yr; P=0.016) and had a higher incidence of renal impairment (RI, 19% vs. 7%, respectively; P=0.057). After 4 cycles of treatment (n=115), there were more partial responses or better in the MPT arm than in the MP arm (57.9% vs. 37.5%; P=0.030). However, DFS and OS were not significantly different between the arms after a median of 23 months follow-up (median OS 26.0 vs. 28.0 months, P=0.655; DFS 21.0 vs. 14.0 months, P=0.342, respectively). Crossover to MPT was required in 11 patients, 57% of whom responded to treatment. A higher rate of grade 3-4 infections was observed in the MPT arm compared with the MP arm (22.4% vs. 7.0%; P=0.033). However, none of these infections were associated with febrile neutropenia. Death within the first 3 months was observed more frequently in the MP arm (n=8, 14.0%) than in the MPT arm (n=2, 3.4%; P=0.053). Long-term discontinuation and dose reduction rates were also analyzed (MPT: 15.5% vs. MP: 5.3%; P=0.072). Although patients treated with MPT were relatively younger and had more frequent RI, better responses and less early mortality were observed in all age groups despite more frequent discontinuation.

Aberrant global methylation patterns affect the molecular pathogenesis and prognosis of multiple myeloma.
    Blood, 2011, Jan-13, Volume: 117, Issue:2

    We used genome-wide methylation microarrays to analyze differences in CpG methylation patterns in cells relevant to the pathogenesis of myeloma plasma cells (B cells, normal plasma cells, monoclonal gammopathy of undetermined significance [MGUS], presentation myeloma, and plasma cell leukemia). We show that methylation patterns in these cell types are capable of distinguishing nonmalignant from malignant cells and the main reason for this difference is hypomethylation of the genome at the transition from MGUS to presentation myeloma. In addition, gene-specific hypermethylation was evident at the myeloma stage. Differential methylation was also evident at the transition from myeloma to plasma cell leukemia with remethylation of the genome, particularly of genes involved in cell-cell signaling and cell adhesion, which may contribute to independence from the bone marrow microenvironment. There was a high degree of methylation variability within presentation myeloma samples, which was associated with cytogenetic differences between samples. More specifically, we found methylation subgroups were defined by translocations and hyperdiploidy, with t(4;14) myeloma having the greatest impact on DNA methylation. Two groups of hyperdiploid samples were identified, on the basis of unsupervised clustering, which had an impact on overall survival. Overall, DNA methylation changes significantly during disease progression and between cytogenetic subgroups.

Testing G-CSF responsiveness predicts the individual susceptibility to infection and consecutive treatment in recipients of high-dose chemotherapy.
    Blood, 2011, Feb-17, Volume: 117, Issue:7

    The individual risk of infection and requirements for medical treatment after high-dose chemotherapy have been unpredictable. In this prospective, multicenter, open-label study we investigated the potential of granulocyte colony-stimulating factor (G-CSF) responsiveness as a predictor. A total of 168 patients with multiple myeloma or lymphoma received a single dose of subcutaneous G-CSF (lenograstim, 263 μg) after high-dose chemotherapy. Highly variable leukocyte peaks were measured and grouped as low (quartile 1; leukocytes 100-10 100/μL), medium (quartile 2; leukocytes > 10 100-18 300/μL), and high (quartiles 3/4; leukocytes > 18 300-44 800/μL). G-CSF responsiveness (low vs medium vs high) was inversely correlated with febrile neutropenia (77% vs 60% vs 48%; P = .0037); the rate of infection, including fever of unknown origin (91% vs 67% vs 54%; P < .0001); days with intravenous antibiotics (9 vs 6 vs 5; P < .0001); and antifungal therapy (P = .042). In multivariate analysis, G-CSF responsiveness remained the only factor significantly associated with infection (P = .016). In addition, G-CSF responsiveness was inversely correlated with grade 3/4 oral mucositis (67% vs 33% vs 23%; P < .0001). G-CSF responsiveness appears as a signature of the myeloid marrow reserve predicting defense against neutropenic infection after intensive chemotherapy. This study is registered at http://www.clinicaltrials.gov as NCT01085058.

Multiple myeloma in serologic complete remission after autologous stem cell transplantation: impact of bone marrow plasma cell assessment by conventional morphology on disease progression.
    Biology of blood and marrow transplantation : journal of the American Society for Blood and Marrow Transplantation, 2011, Volume: 17, Issue:7

    The current definition of complete remission (CR) in multiple myeloma (MM) requires a negative serum and urine immunofixation (IFE) and <5% bone marrow plasma cells (BMPCs). The aim of this study was to determine the value of BMPCs count by standard microscopic evaluation in patients with MM in serologic CR after autologous stem cell transplantation (ASCT). Thirty-five patients with a median follow-up after ASCT of 7.3 years were studied. The percentage of BMPCs was an independent predictor of progression in multivariate model (hazard ratio 2.02, P = .009). Patients with >1.5% BMPCs (median: 0.8%) after ASCT had an increased risk of progression (P = .016) and a trend toward a shorter survival (P = .195). In conclusion, conventional morphology of bone marrow is a useful and rapid tool as a first step to assess the residual tumor mass in patients with MM in CR after ASCT, and it constitutes a strong predictor for disease progression.

Melphalan-prednisolone and vincristine-doxorubicin-dexamethasone chemotherapy followed by prednisolone/interferon maintenance therapy for multiple myeloma: Japan Clinical Oncology Group Study, JCOG0112.
    Japanese journal of clinical oncology, 2011, Volume: 41, Issue:4

    A multicenter phase III study for untreated multiple myeloma was conducted to investigate a switch-induction chemotherapy with melphalan-prednisolone and vincristine-doxorubicin-dexamethasone followed by randomization on maintenance therapy for patients achieving plateau. Between November 2002 and November 2005, 34 patients were registered. The study was closed early because of poor accrual. Thirty-three eligible patients, with a median age of 65 years (range: 47-77 years) were analyzed for the secondary purpose. For induction therapy, 16 patients were treated with vincristine-doxorubicin-dexamethasone and 17 with melphalan-prednisolone initially. In eight cases, induction therapy was switched because of a poor response. Both regimens were well tolerated, but neutropenia, anorexia, constipation and infection with neutropenia were more frequent for vincristine-doxorubicin-dexamethasone. Best response rates were 44% (95% confidence interval, 20-70) and 47% (95% confidence interval, 23-72), respectively, for vincristine-doxorubicin-dexamethasone and melphalan-prednisolone. Vincristine-doxorubicin-dexamethasone/melphalan-prednisolone switch-induction therapy might be feasible and effective for Japanese patients with multiple myeloma.

Fewer bone disease events, improvement in bone remodeling, and evidence of bone healing with bortezomib plus melphalan-prednisone vs. melphalan-prednisone in the phase III VISTA trial in multiple myeloma.
    European journal of haematology, 2011, Volume: 86, Issue:5

      Bone disease is a key presenting feature of myeloma. This post hoc analysis of the phase III VISTA trial of bortezomib plus melphalan-prednisone (VMP) vs. MP in previously untreated myeloma patients assessed clinical bone disease events and changes in alkaline phosphatase (ALP), a marker for osteoblast activation, and serum Dickkopf-1 (DKK-1), an inhibitor of osteoblast differentiation, during treatment..   Patients received nine 6-wk cycles of VMP (bortezomib 1.3 mg/m(2) , days 1, 4, 8, 11, 22, 25, 29, 32, cycles 1-4, days 1, 8, 22, 29, cycles 5-9, plus melphalan 9mg/m(2) and prednisone 60mg/m(2) , days 1-4, cycles 1-9; N=344) or MP alone (N=338)..   Rates of bisphosphonates use during treatment (73% vs. 82%), progression because of worsening bone disease (3% vs. 11%), and requirement for subsequent radiotherapy (3% vs. 8%) were lower with VMP vs. MP. Median maximum ALP increase was significantly higher with VMP vs. MP overall (49.7% vs. 30.3%, P=0.029), and higher by response group (complete response [CR]: 68.7% vs. 43.9%; partial response [PR]: 41.5% vs. 31.2%). Greater maximum ALP increase was strongly associated with achievement of CR (P≤0.0001) and CR/PR (P≤0.01). Median DKK-1 decreased with VMP by 694.4pg/mL and increased with MP by 1273.3pg/mL from baseline to day 4 (P=0.0069). Available radiologic data revealed evidence of bone healing in 6/11 VMP-treated patients, who achieved best responses of three CR, one PR, and two stable disease..   These results suggest a positive effect of bortezomib on bone metabolism and potentially bone healing in myeloma.

Characterization of haematological parameters with bortezomib-melphalan-prednisone versus melphalan-prednisone in newly diagnosed myeloma, with evaluation of long-term outcomes and risk of thromboembolic events with use of erythropoiesis-stimulating agent
    British journal of haematology, 2011, Volume: 153, Issue:2

    Although haematological toxicities, such as anaemia, are common in multiple myeloma (MM), no clear consensus exists on the use and impact of erythropoiesis-stimulating agents (ESA) on outcomes in MM. This analysis characterizes haematological toxicities and associated interventions in the phase III VISTA (Velcade(®) as Initial Standard Therapy in Multiple Myeloma: Assessment with Melphalan and Prednisone) study of bortezomib plus melphalan/prednisone (VMP, n = 344) versus MP (n = 338) in previously untreated MM patients ineligible for high-dose therapy, and evaluates the impact of ESA use or red-blood-cell (RBC) transfusions on outcomes and thromboembolic risk. Incidence of haematological toxicities was similar with VMP and MP; similar rates of interventions and associated complications (e.g. bleeding, febrile neutropenia) were observed. Two hundred thirty three patients received ESA; 204 had RBC transfusions. Frequency of thromboembolic events was low and not affected by ESA use. Median time-to progression (TTP) was similar between ESA/non-ESA [hazard ratio: 1·03 (95% confidence interval 0·76-1·39); P = 0·8478] in both arms (VMP: 19·9/not reached; MP: 15·0/17·5 months). Three-year overall survival (OS) rates were similar between ESA/non-ESA in each arm. Patients receiving RBC transfusions had significantly shorter OS (P < 0·0001) versus non-RBC-transfusion patients. In conclusion, bortezomib did not add to melphalan haematological toxicity. Concomitant ESA use with VMP/MP in previously untreated MM patients did not adversely affect TTP or OS, or increase thromboembolic risk. However, RBC transfusion was associated with significantly shorter survival.

Effect of thalidomide with melphalan and prednisone on health-related quality of life (HRQoL) in elderly patients with newly diagnosed multiple myeloma: a prospective analysis in a randomized trial.
    Annals of hematology, 2011, Volume: 90, Issue:12

    Thalidomide with melphalan/prednisone (MPT) was defined as standard treatment in elderly patients with multiple myeloma (MM) based on five randomized trials. In one of these trials, HOVON49, a prospective health-related quality-of-life (HRQoL) study was initiated in order to assess the impact of thalidomide on QoL. Patients aged >65 years with newly diagnosed MM were randomized to receive melphalan plus prednisone (MP) or MPT, followed by thalidomide maintenance in the MPT arm. Two hundred eighty-four patients were included in this side study (MP, n=149; MPT n=135). HRQoL was assessed with the EORTC Core QoL Questionnaire (QLQ-C30) and the myeloma-specific module (QLQ-MY24) at baseline and at predetermined intervals during treatment. The QLQ-C30 subscales physical function (P=0.044) and constipation (P<0.001) showed an improvement during induction in favour of the MP arm. During thalidomide maintenance, the scores for the QLQ-MY24 paraesthesia became significantly higher in the MPT arm (P<0.001). The QLQ-C30 subscales pain (P=0.12), insomnia (P=0.068), appetite loss (P=0.074) and the QLQ-MY24 item sick (P=0.086) scored marginally better during thalidomide maintenance. The overall QoL-scale QLQ-C30-HRQoL showed a significant time trend towards more favourable mean values during protocol treatment without differences between MP and MPT. For the QLQ-C30 subscales emotional function and future perspectives, difference in favour of the MPT arm from the start of treatment was observed (P=0.018 and P=0.045, respectively) with no significant 'time × arm' interaction, indicating a persistent better patient perspective with MPT treatment. This study shows that the higher frequency of toxicity associated with MPT does not translate into a negative effect on HRQoL and that MPT holds a better patient perspective.

Predictive factors for successful salvage high-dose therapy in patients with multiple myeloma relapsing after autologous blood stem cell transplantation.
    Leukemia & lymphoma, 2011, Volume: 52, Issue:8

    For patients with relapsed or refractory multiple myeloma (MM) treated with a prior high-dose therapy (HDT) followed by autologous peripheral blood stem cell transplantation (PBSCT), the reapplication of HDT is a widely used salvage strategy. In this retrospective study, we report on 55 patients who were treated with salvage HDT at our institution. The conditioning regimen consisted of melphalan 200 mg/m(2) (27%), melphalan 140 mg/m(2) and busulfan 12 mg/kg body weight (40%), or melphalan 200 mg/m(2) and bortezomib 1.3 mg/m(2) (33%). Treatment-related mortality was 5% and response rates were as follows: 9% complete remission, 9% very good partial remission, 56% partial remission, 11% minimal response + stable disease, and 4% progressive disease (5% not assessable). Toxicity was moderate and the median event-free (EFS) and overall survival (OS) were 14 months and 52 months, respectively. The different conditioning regimens did not result in differences in terms of remission rates, EFS and OS, or toxicity. In multivariate analysis a duration of remission of more than 12 months after the first transplant was the only predictive factor for both EFS (p < 0.0001) and OS (p = 0.0001). In conclusion, salvage HDT followed by autologous PBSCT is an effective treatment option for patients with relapsed or refractory MM, while patients with an early relapse after their first transplant do not benefit from this treatment modality.

A randomized trial with melphalan and prednisone versus melphalan and prednisone plus thalidomide in newly diagnosed multiple myeloma patients not eligible for autologous stem cell transplant.
    Leukemia & lymphoma, 2011, Volume: 52, Issue:10

    Several trials comparing the efficacy of standard melphalan and prednisone (MP) therapy with MP plus thalidomide (MPT) in elderly patients with multiple myeloma (MM) have been reported, with inconsistent results. The primary goal of our study was to evaluate the efficacy and toxicity of MP versus MPT in newly diagnosed patients with MM who were transplant-ineligible or over age 65. A total of 135 patients were enrolled. Either minimal response or better or partial response or better were more frequent with MPT treatment (p = 0.001). After a median follow-up of 30 months, median progression-free survival (PFS) and overall survival (OS) were 33 and 52 months for MPT versus 22 and 32 months for MP, respectively. The comparison showed a significant advantage for MPT versus MP in PFS (p = 0.02) and only a trend for OS (p = 0.07). Severe adverse events were observed more frequently with MPT. In conclusion, our results show an improved activity of MPT at a cost of increased toxicity. We believe that MPT can be considered one of the new standard of care for elderly or transplant-ineligible patients with MM.

Lenalidomide maintenance after nonmyeloablative allogeneic stem cell transplantation in multiple myeloma is not feasible: results of the HOVON 76 Trial.
    Blood, 2011, Sep-01, Volume: 118, Issue:9

    To improve the outcome of allogeneic stem cell transplantation (allo-SCT) in multiple myeloma as part of first-line treatment, we prospectively investigated the feasibility and efficacy of lenalidomide maintenance. Patients started maintenance 1 to 6 months after nonmyeloablative allo-SCT. Lenalidomide was dosed 10 mg on days 1 to 21 of a 28-day schedule for a total of 24 cycles. Peripheral blood samples were taken to evaluate immune modulating effects. Thirty-five eligible patients were enrolled, and 30 started with lenalidomide. After 2 cycles, 14 patients (47%) had to stop treatment, mainly because of the development of acute graft versus host disease (GVHD). In total, 13 patients (43%) stopped treatment because of development of GVHD, 5 patients (17%) because of other adverse events, and 5 patients (17%) because of progression. Responses improved in 37% of patients, and the estimated 1-year progression-free survival from start of maintenance was 69% (90% confidence interval, 53%-81%). Lenalidomide increased the frequency of human leukocyte antigen-DR(+) T cells and regulatory T cells, without correlation with clinical parameters. In conclusion, lenalidomide maintenance 10 mg daily after nonmyeloablative allo-SCT with unmanipulated graft in multiple myeloma patients is not feasible, mainly because of the induction of acute GVHD. This trial was registered at www.trialregister.nl as #NTR1645.

Risk of acute myeloid leukemia and myelodysplastic syndromes after multiple myeloma and its precursor disease (MGUS).
    Blood, 2011, Oct-13, Volume: 118, Issue:15

    Using population-based data from Sweden, we identified all multiple myeloma (MM) patients (n = 8740) and 5652 monoclonal gammopathy of undetermined significance (MGUS) patients diagnosed between 1986 and 2005. We calculated standardized incidence rates (SIRs) for all subsequent hematologic and nonhematologic malignancies for MM patients diagnosed before/after 1995 (introduction of high-dose melphalan/autologous stem cell transplantation [HDM-ASCT]) and 2000 (introduction of immunomodulatory drugs [IMiDs]), respectively. MM patients had an 11.51-fold (95% confidence interval: 8.19-15.74) increased risk of acute myeloid leukemia (AML)/myelodysplastic syndromes (MDS); risk was very similar before/after 1995 and 2000, respectively. MGUS patients had an 8.01-fold (5.40-11.43) increased risk of AML/MDS. Risk was confined to IgG/IgA, while no IgM MGUS patients developed AML/MDS; patients with monoclonal-protein (M-protein) concentrations > 1.5 g/dL (SIR = 11.12; 3.61-25.96) had higher risk than those < 1.5 g/dL (SIR = 4.67; 1.71-10.16). An excess risk of nonmelanoma skin cancer was observed subsequent to both MM (SIR = 2.22; 1.74-2.80) and MGUS (SIR = 3.30; 2.76-3.90). Our novel observations of an excess risk for AML/MDS following IgG/IgA (but not IgM) MGUS, and the highest risk associated with M-protein concentrations > 1.5 g/dL, support a role for nontreatment-related factors in plasma cell dyscrasias. AML/MDS risk following MM was the same before/after the introduction of HDM-ASCT. Longer follow-up is needed to characterize second tumor risks in the IMiD era.

Safety and efficacy of bortezomib-melphalan-prednisone-thalidomide followed by bortezomib-thalidomide maintenance (VMPT-VT) versus bortezomib-melphalan-prednisone (VMP) in untreated multiple myeloma patients with renal impairment.
    Blood, 2011, Nov-24, Volume: 118, Issue:22

    We assessed efficacy, safety, and reversal of renal impairment (RI) in untreated patients with multiple myeloma given bortezomib-melphalan-prednisone-thalidomide followed by bortezomib-thalidomide (VMPT-VT) maintenance or bortezomib-melphalan-prednisone (VMP). Exclusion criteria included serum creatinine ≥ 2.5 mg/dL. In the VMPT-VT/VMP arms, severe RI (estimated glomerular filtration rate [eGFR] ≤ 30 mL/min), moderate RI (eGFR 31-50 mL/min), and normal renal function (eGFR > 50 mL/min), were 6%/7.9%, 24.1%/24.9%, and 69.8%/67.2%, respectively. Statistically significant improvements in overall response rates and progression-free survival were observed in VMPT-VT versus VMP arms across renal cohorts, except in severe RI patients. In the VMPT group, severe RI reduced overall survival (OS). RI was reversed in 16/63 (25.4%) patients receiving VMPT-VT versus 31/77 (40.3%) receiving VMP. Multivariate analysis showed male sex (P = .022) and moderate RI (P = .003) significantly predicted RI recovery. VMP patients achieving renal response showed longer OS. In both arms, greater rates of severe hematologic adverse events were associated with RI (eGFR < 50 mL/min), however, therapy discontinuation rates were unaffected. VMPT-VT was superior to VMP for cases with normal renal function and moderate RI, whereas VMPT-VT failed to outperform VMP in patients with severe RI, although the relatively low number of cases analyzed preclude drawing definitive conclusions. VMPT-VT had no advantage in terms of RI reversal over VMP.

Efficiency of supersaturated calcium phosphate mouth rinse treatment in patients receiving high-dose melphalan or BEAM prior to autologous blood stem cell transplantation: a single-center experience.
    Transplantation proceedings, 2011, Volume: 43, Issue:8

    Oral mucositis (OM) is an unresolved problem among patients treated with a high-dose therapy supported by hematopoietic stem cell transplantation (HSCT). We tested the ability of supersaturated calcium phosphate mouth rinse (Caphosol) to ameliorate oral mucosal injury induced by a conditioning regimen.. Thirty-two patients with hematologic malignancies were treated with Caphosol to prevent OM during HSCT procedures. The conditioning regimens for 16 patients were BGNU 300 mg/m2, day 6; ARA-C 200 mg/m2 daily, days 5, 4, 3, 2; VP-16 200 mg/m2 daily, days 5, 4, 3, 2; L-PAM 140 mg/m2, day 1 (BEAM) and for 16 patients, MEL 200 (non-Hodgkin's lymphoma). A control group was composed of 24 consecutive patients, who had been treated with HSCT before Caphosol was available. The source of the graft was autologous peripheral blood.. Among patients treated with Caphosol no one had to receive total parenteral nutrition. Among the BEAM group no one experienced III to IV degree OM compared with 40% of the control group. The median OM duration was 2.25 days versus controls of 8.6, (P<.001); only one patient received opioids versus 100% of controls. In the MEL 200 group, 93.7% of patients developed 0 to II degree OM vs 94% of the control group (P=.74) with median duration of 1, 73 days versus 2.42 for the controls (P=.73). In both control and Caphosol cohorts one patient received opioids.. Caphosol may reduce the incidence, severity, and duration of oral mucositis and decrease the number of days with painkillers among patients treated with a BEAM but not a Mel 200 regimen.

A prospective randomized trial of two popular mononuclear cell collection sets for autologous peripheral blood stem cell collection in multiple myeloma.
    Transfusion, 2010, Volume: 50, Issue:1

    The COBE Spectra AutoPBSC collection set (AUTO-kit; CaridianBCT) is a popular dual-stage collection set for peripheral blood progenitor (PBPC) collection. Although the AUTO-kit is purportedly equivalent to the white blood cell (WBC) collection set (WBC-kit) for PBPC collection, improved CD34 yields after switching from the AUTO-kit to the WBC-kit were anecdotally observed, particularly in patients with higher WBC counts. A prospective, randomized trial of the AUTO- and WBC-kits for PBPC collection in multiple myeloma (MM) patients was therefore designed.. Sixty-eight MM patients were prospectively randomly assigned to either the WBC-kit or the AUTO-kit for PBPC collection. Primary study variables included the number of leukapheresis procedures per transplant, CD34/kg yield per procedure, and cumulative CD34/kg yield per mobilization cycle. Results were compared relative to collection kit and mobilization regimen. Statistics and graphics were performed with commercial software.. CD34/kg yields were higher with the WBC-kit, with 94% of chemotherapy-mobilized MM patients collecting 6 million CD34/kg in a single mobilization (p = 0.06). The WBC-kit also had a faster CD34 collection rate relative to peripheral CD34 counts. The AUTO-kit was significantly sensitive to high WBC counts, with a 50% decrease in CD34 collection efficiency and CD34 collection rate. This effect was specific to MM and not observed in lymphoma patients. Granulocyte-colony-stimulating factor mobilization and the AUTO-kit were associated with an increased incidence and severity of infusion reactions.. The WBC-kit performed consistently better than the AUTO-kit for PBPC collection in chemotherapy-mobilized MM patients, with fewer procedures per mobilization, superior collection rates, and a decreased incidence of infusion reactions.

"Short course" bortezomib plus melphalan and prednisone as induction prior to transplant or as frontline therapy for nontransplant candidates in patients with previously untreated multiple myeloma.
    Biology of blood and marrow transplantation : journal of the American Society for Blood and Marrow Transplantation, 2010, Volume: 16, Issue:1

    The purpose of this study was to evaluate the efficacy and safety of short-course bortezomib, melphalan, prednisone (VMP) in previously untreated multiple myeloma as frontline therapy for transplant-ineligible patients and induction prior to autologous stem cell transplantation (ASCT). Patients received up to 6 28-day cycles of bortezomib 1.3 mg/m(2), days 1, 4, 8, and 11, plus melphalan 6 mg/m(2) and prednisone 60 mg/m(2), days 1-7. After 2-6 cycles, eligible and consenting patients could proceed to ASCT. Responses were assessed by International Uniform Response Criteria. The primary endpoint was complete response (CR) rate with VMP. Forty-five patients were enrolled. Among 44 evaluable patients, response rate was 95%, including 18% >or=CR (9% stringent CR), 27% very good partial responses (VGPR), and 50% partial responses (PR). Twenty patients proceeded to ASCT. Stem cell collection was successful in all; median yield was 5.6 x 10(6) CD34(+) cells/kg. Posttransplant response rates were 30% >or=CR (10% stringent CR), 65% VGPR, and 5% PR. After median follow-up of 14.0/14.6 months, median time to progression and progression-free survival were both 19.8/27.9 months in non-ASCT/ASCT patients. Seven patients have died; 1-year survival rates were 82%/95% in non-ASCT/ASCT patients. The most common grade 3/4 toxicities were thrombocytopenia (20%), neutropenia (28%), and infection (9%). Peripheral neuropathy grade 2-4 was the most common nonhematopoietic side effect occurring 17 patients (38%), although it was typically reversible, and only 5 patients (11%) discontinued therapy as a result of it. Short-course VMP is highly effective and generally well tolerated, both as initial treatment in non-ASCT patients and induction prior to ASCT. VMP did not negatively affect stem cell collection. Longer follow-up and prospective phase III trials are required to validate these initial observations.

A randomized phase 3 study on the effect of thalidomide combined with adriamycin, dexamethasone, and high-dose melphalan, followed by thalidomide maintenance in patients with multiple myeloma.
    Blood, 2010, Feb-11, Volume: 115, Issue:6

    The phase 3 trial HOVON-50 was designed to evaluate the effect of thalidomide during induction treatment and as maintenance in patients with multiple myeloma who were transplant candidates. A total of 556 patients was randomly assigned to arm A: 3 cycles of vincristine, adriamycin, and dexamethasone, or to arm B: thalidomide 200 mg orally, days 1 to 28 plus adriamycin and dexamethasone. After induction therapy and stem cell mobilization, patients were to receive high-dose melphalan, 200 mg/m(2), followed by maintenance with alpha-interferon (arm A) or thalidomide 50 mg daily (arm B). Thalidomide significantly improved overall response rate as well as quality of the response before and after high dose melphalan. Best overall response rate on protocol was 88% and 79% (P = .005), at least very good partial remission 66% and 54% (P = .005), and complete remission 31% and 23% (P = .04), respectively, in favor of the thalidomide arm. Thalidomide also significantly improved event-free survival from median 22 months to 34 months (P < .001), and prolonged progression free from median 25 months to 34 months (P < .001). Median survival was longer in the thalidomide arm, 73 versus 60 months; however, this difference was not significant (P = .77). Patients randomized to thalidomide had strongly reduced survival after relapse. This trial was registered on www.controlled-trials.com as ISRCTN06413384.

Bortezomib and high-dose melphalan as conditioning regimen before autologous stem cell transplantation in patients with de novo multiple myeloma: a phase 2 study of the Intergroupe Francophone du Myelome (IFM).
    Blood, 2010, Jan-07, Volume: 115, Issue:1

    Autologous stem cell transplantation (ASCT) is recommended for younger patients with newly diagnosed multiple myeloma. Achieving complete response (CR) or at least very good partial response (VGPR) is a major prognostic factor for survival with 20% to 30% of patients achieving CR after ASCT. Bortezomib has shown synergistic effects with melphalan and no prolonged hematologic toxicity. In this Intergroupe Francophone du Myélome (IFM) phase 2 study, 54 untreated patients were enrolled between July and December 2007 to receive bortezomib (1 mg/m(2) x 4) and melphalan (200 mg/m(2)) as conditioning regimen (Bor-HDM). Overall, 70% of patients achieved at least VGPR, including 17 patients with CR (32%) after ASCT. No toxic deaths were observed. Bortezomib did not increase hematologic toxicity. Only 1 grade 3 to 4 peripheral neuropathy was reported. A matched control analysis was conducted comparing our cohort with patients from the IFM 2005-01 trial (HDM alone). Patients were matched for response to induction therapy and type of induction: CR was higher in the Bor-HDM group (35% vs 11%; P = .001), regardless of induction therapy. These results suggest that Bor-HDM is a safe and promising conditioning regimen. Randomized studies are needed to assess whether this conditioning regimen is superior to HDM alone. This trial was registered at www.clinicaltrials.gov as NCT00642395.

Melphalan 200 mg/m(2) versus melphalan 100 mg/m(2) in newly diagnosed myeloma patients: a prospective, multicenter phase 3 study.
    Blood, 2010, Mar-11, Volume: 115, Issue:10

    High-dose (200 mg/m(2), MEL200) and intermediate-dose melphalan (100 mg/m(2), MEL100) showed significant activity in myeloma. In a phase 3 study, 298 patients were randomly assigned to receive 2 autologous transplantations after conditioning with MEL200 or MEL100. Ninety-six of 149 (64%) completed MEL200 and 103 of 149 (69%) MEL100. Best response to MEL200 was: complete remission 22 of 149 (15%); partial remission 95 of 149 (64%), for an overall response rate of 79%. Best response to MEL100 was: complete remission 12 of 149 (8%); partial remission 95 of 149 (64%), for an overall response rate of 72%. Overall survival did not differ (P = .13); median progression-free survival (31.4 vs 26.2 months, P = .01), median time to progression (34.4 vs 27.0 months, P = .014) were longer in the MEL200. Treatment-related mortality was 3.1% in the MEL200 and 2.9% in the MEL100 group. Severe neutropenia and infections were marginally superior, whereas severe thrombocytopenia, mucositis, gastrointestinal adverse events, and the overall occurrence of at least 1 nonhematologic grade 3 or 4 adverse event were significantly higher in the MEL200 cohort. We conclude that MEL200 leads to longer remission duration and should be considered the standard conditioning regimen for autologous transplantation. This study was registered at www.clinicaltrials.gov as #NCT00950768.

Bortezomib, thalidomide, dexamethasone induction therapy followed by melphalan, prednisolone, thalidomide consolidation therapy as a first line of treatment for patients with multiple myeloma who are non-transplant candidates: results of the Korean Multip
    Annals of hematology, 2010, Volume: 89, Issue:5

    Bortezomib (VELCADE), thalidomide and dexamethasone (VTD), as well as melphalan, prednisolone, and thalidomide (MPT) therapy, are highly effective in patients with multiple myeloma. We evaluated the responses and survival times of 35 patients treated with VTD followed by MPT. All patients were newly diagnosed and non-transplantation candidates. Patients received six cycles of VTD, which were followed by eight cycles of MPT. Approximately 97% of patients exhibited early responses to therapy, as early as the second cycle of VTD. Thirty percent of the responses were high quality, which was defined as a complete response (CR), a near-CR or a very good partial response. High-risk patients were defined as patients with any of the following aberrations: del(13), t(4;14), or del(17p). The remaining patients were defined as standard risk. Eleven high-risk patients showed 100% response rates, including 91% high-quality responses. In contrast, 13 standard-risk patients exhibited 92% response rates, including 61% high-quality responses. The overall 2-year survival rates were 60% in high-risk patients and 85% in standard-risk patients, which was not significantly different. As a first-line therapy, VTD followed by MPT has the potential to provide high-quality responses with durable remission among elderly and high-risk patients (clinicaltrials.gov identifier: NCT00320476).

Bortezomib as induction before autologous transplantation, followed by lenalidomide as consolidation-maintenance in untreated multiple myeloma patients.
    Journal of clinical oncology : official journal of the American Society of Clinical Oncology, 2010, Feb-10, Volume: 28, Issue:5

    PURPOSE To evaluate the effect of bortezomib as induction therapy before autologous transplantation, followed by lenalidomide as consolidation-maintenance in myeloma patients. PATIENTS AND METHODS Newly diagnosed patients age 65 to 75 years were eligible. Induction (bortezomib, doxorubicin, and dexamethasone [PAD]) included four 21-day cycles of bortezomib (1.3 mg/m(2) on days 1, 4, 8, and 11), pegylated liposomal doxorubicin (30 mg/m(2) on day 4), and dexamethasone (40 mg/d; cycle 1: days 1 to 4, 8 to 11, and 15 to 18; cycles 2 to 4: days 1 to 4). Autologous transplantation was tandem melphalan 100 mg/m(2) (MEL100) and stem-cell support. Consolidation included four 28-day cycles of lenalidomide (25 mg/d on days 1 to 21 every 28 days) plus prednisone (50 mg every other day), followed by maintenance with lenalidomide (LP-L; 10 mg/d on days 1 to 21) until relapse. Primary end points were safety (incidence of grade 3 to 4 adverse events [AEs]) and efficacy (response rate). Results A total of 102 patients were enrolled. In a per-protocol analysis, after PAD, 58% of patients had very good partial response (VGPR) or better, including 13% with complete response (CR); after MEL100, 82% of patients had at least VGPR and 38% had CR; and after LP-L, 86% of patients had at least VGPR and 66% had CR. After median follow-up time of 21 months, the 2-year progression-free survival rate was 69%, and the 2-year overall survival rate was 86%. During induction, treatment-related mortality was 3%; grade 3 to 4 AEs included thrombocytopenia (17%), neutropenia (10%), peripheral neuropathy (16%), and pneumonia (10%). During consolidation-maintenance, grade 3 to 4 AEs were neutropenia (16%), thrombocytopenia (6%), pneumonia (5%), and cutaneous rash (4%). CONCLUSION Bortezomib as induction before autologous transplantation, followed by lenalidomide as consolidation-maintenance, is an effective regimen.

Melphalan, prednisone, thalidomide and defibrotide in relapsed/refractory multiple myeloma: results of a multicenter phase I/II trial.
    Haematologica, 2010, Volume: 95, Issue:7

    Defibrotide is a novel orally bioavailable polydisperse oligonucleotide with anti-thrombotic and anti-adhesive effects. In SCID/NOD mice, defibrotide showed activity in human myeloma xenografts. This phase I/II study was conducted to identify the most appropriate dose of defibrotide in combination with melphalan, prednisone and thalidomide in patients with relapsed and relapsed/refractory multiple myeloma, and to determine its safety and tolerability as part of this regimen.. This was a phase I/II, multicenter, dose-escalating, non-comparative, open label study. Oral melphalan was administered at a dose of 0.25 mg/kg on days 1-4, prednisone at a dose of 1.5 mg/kg also on days 1-4 and thalidomide at a dose of 50-100 mg/day continuously. Defibrotide was administered orally at three dose-levels: 2.4, 4.8 or 7.2 g on days 1-4 and 1.6, 3.2, or 4.8 g on days 5-35.. Twenty-four patients with relapsed/refractory multiple myeloma were enrolled. No dose-limiting toxicity was observed. In all patients, the complete response plus very good partial response rate was 9%, and the partial response rate was 43%. The 1-year progression-free survival and 1-year overall survival rates were 34% and 90%, respectively. The most frequent grade 3-4 adverse events included neutropenia, thrombocytopenia, anemia and fatigue. Deep vein thrombosis was reported in only one patient.. This combination of melphalan, prednisone and thalidomide together with defibrotide showed anti-tumor activity with a favorable tolerability. The maximum tolerated dose of defibrotide was identified as 7.2 g p.o. on days 1-4 followed by 4.8 g p.o. on days 5-35. Further trials are needed to confirm the role of this regimen and to evaluate the combination of defibrotide with new drugs.

ThaDD plus high dose therapy and autologous stem cell transplantation does not appear superior to ThaDD plus maintenance in elderly patients with de novo multiple myeloma.
    European journal of haematology, 2010, Volume: 84, Issue:6

    With the aim to address the issue whether high-dose therapy (HDT) is required after new drugs combinations to improve outcome of elderly newly diagnosed multiple myeloma (MM) patients, we compared the toxicity and the outcome of ThaDD plus maintenance to those of ThaDD plus HDT-autologous stem cell transplantation (ASCT).. Sixty-two patients not eligible for HDT receiving six courses of ThaDD regimen plus maintenance with thalidomide were compared to 26 patients eligible for HDT treated with four courses of ThaDD followed by melphalan 100-200 mg/m(2) and ASCT. The two groups were matched for the main characteristics except for age favouring the HDT group.. Complete remission (CR) obtained with ThaDD plus maintenance was 24% whereas it was 57% after ThaDD plus HDT-ASCT (P = 0.0232). However, after a median follow-up of 36 months, median time to progression (TTP) and progression free survival (PFS) of the group of patients undergone HDT were not significantly different to those of patients receiving ThaDD plus maintenance (32 vs. 31 months: P = 0.962; 32 vs. 29 months: P = 0.726, respectively). Five-year overall survival (OS) was 49% in the first group and 46% in the latter one (P = 0.404). As expected, a significantly higher incidence of grade 3-4 neutropenia, thrombocytopenia, infections, mucositis and alopecia were observed in the ThaDD plus HDT group. Our results suggest that in elderly MM patients ThaDD plus HDT, albeit significantly increases CR rate, seems to be equivalent to ThaDD plus maintenance in terms of TTP, PFS and OS. These results challenge the requirement for HDT consolidation in this subset of patients.

Bortezomib plus melphalan and prednisone compared with melphalan and prednisone in previously untreated multiple myeloma: updated follow-up and impact of subsequent therapy in the phase III VISTA trial.
    Journal of clinical oncology : official journal of the American Society of Clinical Oncology, 2010, May-01, Volume: 28, Issue:13

    The purpose of this study was to confirm overall survival (OS) and other clinical benefits with bortezomib, melphalan, and prednisone (VMP) versus melphalan and prednisone (MP) in the phase III VISTA (Velcade as Initial Standard Therapy in Multiple Myeloma) trial after prolonged follow-up, and evaluate the impact of subsequent therapies.. Previously untreated symptomatic patients with myeloma ineligible for high-dose therapy received up to nine 6-week cycles of VMP (n = 344) or MP (n = 338).. With a median follow-up of 36.7 months, there was a 35% reduced risk of death with VMP versus MP (hazard ratio, 0.653; P < .001); median OS was not reached with VMP versus 43 months with MP; 3-year OS rates were 68.5% versus 54.0%. Response rates to subsequent thalidomide- (41% v 53%) and lenalidomide-based therapies (59% v 52%) appeared similar after VMP or MP; response rates to subsequent bortezomib-based therapy were 47% versus 59%. Among patients treated with VMP (n = 178) and MP (n = 233), median survival from start of subsequent therapy was 30.2 and 21.9 months, respectively, and there was no difference in survival from salvage among patients who received subsequent bortezomib, thalidomide, or lenalidomide. Rates of adverse events were higher with VMP versus MP during cycles 1 to 4, but similar during cycles 5 to 9. With VMP, 79% of peripheral neuropathy events improved within a median of 1.9 months; 60% completely resolved within a median of 5.7 months.. VMP significantly prolongs OS versus MP after lengthy follow-up and extensive subsequent antimyeloma therapy. First-line bortezomib use does not induce more resistant relapse. VMP used upfront appears more beneficial than first treating with conventional agents and saving bortezomib- and other novel agent-based treatment until relapse.

Lenalidomide, melphalan, prednisone and thalidomide (RMPT) for relapsed/refractory multiple myeloma.
    Leukemia, 2010, Volume: 24, Issue:5

    This multicenter, open-label, non-comparative phase II trial evaluated the safety and efficacy of salvage therapy with lenalidomide, melphalan, prednisone and thalidomide (RMPT) in patients with relapsed/refractory multiple myeloma (MM). Oral lenalidomide (10 mg/day) was administered on days 1-21, and oral melphalan (0.18 mg/kg) and oral prednisone (2 mg/kg) on days 1-4 of each 28-day cycle. Thalidomide was administered at 50 mg/day or 100 mg/day on days 1-28; six cycles were administered in total. Maintenance included lenalidomide 10 mg/day on days 1-21, until unacceptable adverse events or disease progression. Aspirin (100 mg/day) was given as thromboprophylaxis. A total of 44 patients with relapsed/refractory MM were enrolled and 75% achieved at least a partial response (PR), including 32% very good PR (VGPR) and 2% complete response (CR). The 1-year progression-free survival (PFS) was 51% and the 1-year overall survival (OS) from study entry was 72%. Grade 4 hematologic adverse events included neutropenia (18%), thrombocytopenia (7%) and anemia (2%). Grade 3 non-hematologic adverse events were infections (14%), neurological toxicity (4.5%) and fatigue (7%). No grade 3/4 thromboembolic events or peripheral neuropathy were reported. In conclusion, RMPT is an active salvage therapy with good efficacy and manageable side effects. This study represents the basis for larger phase III randomized trials.

XBP1s levels are implicated in the biology and outcome of myeloma mediating different clinical outcomes to thalidomide-based treatments.
    Blood, 2010, Jul-15, Volume: 116, Issue:2

    Immunoglobulin production by myeloma plasma cells depends on the unfolded protein response for protein production and folding. Recent studies have highlighted the importance of IRE1alpha and X box binding protein 1 (XBP1), key members of this pathway, in normal B-plasma cell development. We have determined the gene expression levels of IRE1alpha, XBP1, XBP1UNSPLICED (XBP1u), and XBP1SPLICED (XBP1s) in a series of patients with myeloma and correlated findings with clinical outcome. We show that IRE1alpha and XBP1 are highly expressed and that patients with low XBP1s/u ratios have a significantly better overall survival. XBP1s is an independent prognostic marker and can be used with beta2 microglobulin and t(4;14) to identify a group of patients with a poor outcome. Furthermore, we show the beneficial therapeutic effects of thalidomide in patients with low XBP1s/u ratios. This study highlights the importance of XBP1 in myeloma and its significance as an independent prognostic marker and as a predictor of thalidomide response.

Melphalan and prednisone plus thalidomide or placebo in elderly patients with multiple myeloma.
    Blood, 2010, Sep-02, Volume: 116, Issue:9

    In this double-blind, placebo-controlled study, 363 patients with untreated multiple myeloma were randomized to receive either melphalan-prednisone and thalidomide (MPT) or melphalan-prednisone and placebo (MP). The dose of melphalan was 0.25 mg/kg and prednisone was 100 mg given daily for 4 days every 6 weeks until plateau phase. The dose of thalidomide/placebo was escalated to 400 mg daily until plateau phase and thereafter reduced to 200 mg daily until progression. A total of 357 patients were analyzed. Partial response was 34% and 33%, and very good partial response or better was 23% and 7% in the MPT and MP arms, respectively (P < .001). There was no significant difference in progression-free or overall survival, with median survival being 29 months in the MPT arm and 32 months in the MP arm. Most quality of life outcomes improved equally in both arms, apart from constipation, which was markedly increased in the MPT arm. Constipation, neuropathy, nonneuropathy neurologic toxicity, and skin reactions were significantly more frequent in the MPT arm. The number of thromboembolic events was equal in the 2 treatment arms. In conclusion, MPT had a significant antimyeloma effect, but this did not translate into improved survival. This trial was registered at www.clinicaltrials.gov as #NCT00218855.

A Phase II study of (153)Sm-EDTMP and high-dose melphalan as a peripheral blood stem cell conditioning regimen in patients with multiple myeloma.
    American journal of hematology, 2010, Volume: 85, Issue:6

    Multiple myeloma (MM) remains an incurable illness affecting nearly 20,000 individuals in the United States per year. High-dose melphalan (HDM) with autologous hematopoietic stem cell support (ASCT) is one of the mainstays of therapy for younger patients, but little advancement has been made with regards to conditioning regimens. We opted to combine (153)Samarium ethylenediaminetetramethylenephosphonate ((153)Sm-EDTMP), a radiopharmaceutical approved for the palliation of pain caused by metastatic bone lesions, with HDM and ASCT in a Phase II study. Individualized doses of (153)Sm were based on dosimetry and were calculated to deliver 40 Gy to the bone marrow. The therapeutic dose of (153)Sm-EDTMP was followed by HDM and ASCT. Forty-six patients with newly diagnosed or relapsed disease were treated. Study patients were compared to 102 patients contemporaneously treated with HDM and ASCT. Fifty-nine percent of study patients achieved a very good partial response (VGPR) or better. With a median follow-up of 7.1 years, the median overall survival and progression free survival (PFS) from study registration was 6.2 years (95% CI 4.6-7.5 years) and 1.5 years (1.1-2.2 years), respectively, which compared favorably to contemporaneously treated non-study patients. Addition of high-dose (153)Sm-EDTMP to melphalan conditioning appears to be safe, well tolerated, and worthy of further study in the context of novel agents and in the Phase III setting.

Phase III study of the value of thalidomide added to melphalan plus prednisone in elderly patients with newly diagnosed multiple myeloma: the HOVON 49 Study.
    Journal of clinical oncology : official journal of the American Society of Clinical Oncology, 2010, Jul-01, Volume: 28, Issue:19

    For several decades, the treatment of elderly patients with multiple myeloma (MM) has consisted of melphalan and prednisone (MP). The Dutch-Belgium Hemato-Oncology Cooperative Group (HOVON) investigated the efficacy of thalidomide added to MP (MP-T) in a randomized phase III trial. The objective of this study was to investigate the efficacy, toxicity, and effects on quality of life of MP-T.. A randomized phase III trial compared standard MP with MP-T (thalidomide 200 mg/d) in newly diagnosed patients with multiple myeloma older than age 65 years. Maintenance therapy with thalidomide 50 mg/d was administered to patients after MP-T until relapse. The primary end point was event-free survival (EFS); response rate, overall survival (OS), and progression-free survival (PFS) were secondary end points.. An intent-to-treat analysis of 333 evaluable patients showed significantly higher response rates in MP-T-treated patients compared with MP-treated patients a response (> or = partial response: 66% v 45%, respectively; P < .001; and > or = very good partial response [VGPR]: 27% v 10%, respectively; P < .001). EFS was 13 months with MP-T versus 9 months with MP (P < .001). OS was 40 months with MP-T versus 31 months with MP (P = .05).. This study demonstrates that thalidomide improves the response rate and VGPR in elderly patients with newly diagnosed MM. MP-T also results in a better EFS, PFS, and OS.

Superior outcomes associated with complete response in newly diagnosed multiple myeloma patients treated with nonintensive therapy: analysis of the phase 3 VISTA study of bortezomib plus melphalan-prednisone versus melphalan-prednisone.
    Blood, 2010, Nov-11, Volume: 116, Issue:19

    The phase 3 Velcade as Initial Standard Therapy in Multiple Myeloma: Assessment with Melphalan and Prednisone study in newly diagnosed multiple myeloma patients ineligible for high-dose therapy demonstrated that bortezomib-melphalan-prednisone (VMP) was superior to melphalan-prednisone across all efficacy end points. We assessed the prognostic impact of response on time-to-event parameters in the intent-to-treat population. Patients received nine 6-week cycles of treatment. Time to progression, time to next therapy, and treatment-free interval were associated with quality of response. When European Group for Blood and Marrow Transplantation criteria were used, complete response (CR) was associated with significantly longer time to progression (hazard ratio [HR] = 0.45, P = .004), time to next therapy (HR = 0.46, P = .0004), and treatment-free interval (HR = 0.38, P < .0001) versus partial response, but there was no significant difference in overall survival (HR = 0.87, P = .54); similar differences were seen with CR versus very good partial response by uniform criteria. Quality of response improved with prolonged VMP treatment, with 28% of CRs achieved during cycles 5-9. CR duration appeared similar among patients with "early" (cycles 1-4) and "late" CRs (cycles 5-9) and among patients receiving 9 versus < 9 cycles of bortezomib within VMP. These results highlight that CR is an important treatment goal and support prolonged VMP therapy to achieve maximal response. This study is registered at http://www.clinicaltrials.gov as NCT00111319.

Busulfan 12 mg/kg plus melphalan 140 mg/m2 versus melphalan 200 mg/m2 as conditioning regimens for autologous transplantation in newly diagnosed multiple myeloma patients included in the PETHEMA/GEM2000 study.
    Haematologica, 2010, Volume: 95, Issue:11

    The aim of this study was to compare the long-term safety and efficacy of oral busulfan 12 mg/kg plus melphalan 140 mg/m(2) and melphalan 200 mg/m(2) as conditioning regimens for autologous stem cell transplantation in newly diagnosed patients with multiple myeloma in the GEM2000 study.. The first 225 patients received oral busulfan 12 mg/kg plus melphalan 140 mg/m(2); because of a high frequency of veno-occlusive disease, the protocol was amended and a further 542 patients received melphalan 200 mg/m(2).. Engraftment and hospitalization times were similar in both groups. Oral busulfan 12 mg/kg plus melphalan 140 mg/m(2) resulted in higher transplant-related mortality (8.4% versus 3.5%; P=0.002) due to the increased frequency of veno-occlusive disease in this group. Response rates were similar in both arms. With respective median follow-ups of 72 and 47 months, the median progression-free survival was significantly longer with busulfan plus melphalan (41 versus 31 months; P=0.009), although survival was similar to that in the melphalan 200 mg/m(2) group. However, access to novel agents as salvage therapy after relapse/progression was significantly lower for patients receiving busulfan plus melphalan (43%) than for those receiving melphalan 200 mg/m(2) (58%; P=0.01).. Conditioning with oral busulfan 12 mg/kg plus melphalan 140 mg/m(2) was associated with longer progression-free survival but equivalent survival to that achieved with melphalan 200 mg/m(2) but this should be counterbalanced against the higher frequency of veno-occlusive disease-related deaths. This latter fact together with the limited access to novel salvage therapies in patients conditioned with oral busulfan 12 mg/kg plus melphalan 140 mg/m(2) may explain the absence of a survival difference. Oral busulfan was used in the present study; use of the intravenous formulation may reduce toxicity and result in greater efficacy, and warrants further investigation in myeloma patients.

Improved survival for multiple myeloma in denmark based on autologous stem cell transplantation and novel drug therapy in collaborative trials: analysis of accrual, prognostic variables, selection bias, and clinical behavior on survival in more than 1200
    Clinical lymphoma, myeloma & leukemia, 2010, Volume: 10, Issue:4

    An unexplained survival difference was observed in the Nordic Myeloma Study Group (NMSG) high-dose therapy trial 5/94 in Denmark compared with Sweden and Norway; however, this difference was eliminated in the subsequent NMSG trial 7/98. It was hypothesized that a detailed analysis of potential explanations would reveal important information for future designs of clinical trials for multiple myeloma (MM) patients in Denmark.. The analysis is based on 3 consecutive clinical trials coordinated by NMSG from 1990 to 2000: NMSG 4/90 including 583 patients, NMSG 5/94 including 274 patients and NMSG 7/98 including 414 patients with newly diagnosed MM. Event-free and total survival rates were calculated according to the Kaplan-Meier method, and survival comparisons were made by the log-rank test. The Cox proportional hazards regression model was used to estimate the prognostic importance of selected variables.. The analysis revealed no differences in disease stages, prognostic variables, or inclusion bias at diagnosis between the 3 consecutive NMSG trials. However, the number of initial treatment failures was low, and post-relapse survival was superior in Swedish patients as compared to Danish patients. These differences were explained by a defensive clinical practice in Denmark during 1994-1997 for patients with poor risk refractory or relapsed disease.. These initially observed differences were subsequently eliminated most likely as a consequence of international collaboration improving diagnosis, research infrastructure, clinical training, and education as planned within the European Myeloma Network (EMN).

Bortezomib, melphalan, and prednisone versus bortezomib, thalidomide, and prednisone as induction therapy followed by maintenance treatment with bortezomib and thalidomide versus bortezomib and prednisone in elderly patients with untreated multiple myelom
    The Lancet. Oncology, 2010, Volume: 11, Issue:10

    Bortezomib plus melphalan and prednisone (VMP) is significantly better than melphalan plus prednisone alone for elderly patients with untreated multiple myeloma; however, toxic effects are high. We investigated a novel and less intensive bortezomib-based regimen to maintain efficacy and to reduce toxic effects.. Between March, 2006, and October, 2008, 260 patients with untreated multiple myeloma, 65 years and older, from 63 Spanish centres, were randomly assigned to receive six cycles of VMP (n=130) or bortezomib plus thalidomide and prednisone (VTP; n=130) as induction therapy, consisting of one cycle of bortezomib twice per week for 6 weeks (1·3 mg/m² on days 1, 4, 8, 11, 22, 25, 29, and 32), plus either melphalan (9 mg/m² on days 1-4) or daily thalidomide (100 mg), and prednisone (60 mg/m² on days 1-4). The first cycle was followed by five cycles of bortezomib once per week for 5 weeks (1·3 mg/m² on days 1, 8, 15, and 22) plus the same doses of melphalan plus prednisone and thalidomide plus prednisone. 178 patients completed the six induction cycles and were randomly assigned to maintenance therapy with bortezomib plus prednisone (n=87) or bortezomib plus thalidomide (n=91), consisting of one conventional cycle of bortezomib for 3 weeks (1·3 mg/m² on days 1, 4, 8, and 11) every 3 months, plus either prednisone (50 mg every other day) or thalidomide (50 mg per day), for up to 3 years. Treatment codes were generated with a computerised random number generator, and neither participants nor study personnel were masked to treatment. The primary endpoint was response rate in induction and maintenance phases. Analysis was by intention to treat. This trial is registered with ClinicalTrials.gov, number NCT00443235.. In the induction phase, 105 (81%) patients in the VTP group and 104 (80%) in the VMP group achieved partial responses or better (p=0·9), including 36 (28%) and 26 (20%) complete remissions, respectively (p=0·2). Treatment with VTP resulted in more serious adverse events (40 [31%] vs 20 [15%], p=0·01) and discontinuations (22 [17%] vs 15 [12%], p=0·03) than did treatment with VMP. The most common toxicities (grade 3 or worse) were infections (one [1%] in the VTP group vs nine [7%] in the VMP group), cardiac events (11 [8%] vs 0), and peripheral neuropathy (nine [7%] vs 12 [9%]). After maintenance therapy, the complete remission rate was 42% (40 [44%] patients in complete remission in the bortezomib plus thalidomide group, 34 [39%] in the bortezomib plus prednisone group). No grade 3 or worse haematological toxicities were recorded during maintenance therapy; two (2%) patients in the bortezomib plus prednisone group and six (7%) in the bortezomib plus thalidomide group developed peripheral neuropathy.. Reduced-intensity induction with a bortezomib-based regimen, followed by maintenance, is a safe and effective treatment for elderly patients with multiple myeloma..

A phase I/II trial combining high-dose melphalan and autologous transplant with bortezomib for multiple myeloma: a dose- and schedule-finding study.
    Clinical cancer research : an official journal of the American Association for Cancer Research, 2010, Oct-15, Volume: 16, Issue:20

    We did a randomized phase I/II trial designed to evaluate the safety and efficacy of combining the proteasome inhibitor bortezomib with high-dose melphalan as the conditioning for high-dose therapy and autologous transplant for myeloma.. Enrolled patients were limited to those who did not achieve a very good partial remission (VGPR) following one or more induction regimens, and were randomized to receive a single escalating dose of bortezomib (1.0, 1.3, or 1.6 mg/m(2)) either 24 hours before or 24 hours after high-dose melphalan. Dose escalation was based on the escalation with overdose control (EWOC), a Bayesian statistical model. Bone marrow aspirates were collected before initiation of therapy and at the time of transplant to evaluate which sequence resulted in maximal plasma cell apoptosis, and response to transplant was assessed by the International Myeloma Working Group criteria.. Among 39 randomized patients, 20 received bortezomib after melphalan and 19 received bortezomib before melphalan. Toxicities and posttransplant hematopoietic recovery rates were similar between arms. The overall response rate for all patients was 87%, with 51% achieving a VGPR or better. Pharmacodynamic studies showed greater plasma cell apoptosis among patients who received bortezomib following melphalan.. The use of bortezomib in conjunction with high-dose melphalan is safe, with data suggesting improved efficacy. A single dose of bortezomib administered after high-dose melphalan is the recommended dose and schedule for future clinical investigation.

Efficacy and safety of once-weekly bortezomib in multiple myeloma patients.
    Blood, 2010, Dec-02, Volume: 116, Issue:23

    In a recent phase 3 trial, bortezomib-melphalan-prednisone-thalidomide followed by maintenance treatment with bortezomib-thalidomide demonstrated superior efficacy compared with bortezomib-melphalan-prednisone. To decrease neurologic toxicities, the protocol was amended and patients in both arms received once-weekly instead of the initial twice-weekly bortezomib infusions: 372 patients received once-weekly and 139 twice-weekly bortezomib. In this post-hoc analysis we assessed the impact of the schedule change on clinical outcomes and safety. Long-term outcomes appeared similar: 3-year progression-free survival rate was 50% in the once-weekly and 47% in the twice-weekly group (P > .999), and 3-year overall survival rate was 88% and 89%, respectively (P = .54). The complete response rate was 30% in the once-weekly and 35% in the twice-weekly group (P = .27). Nonhematologic grade 3/4 adverse events were reported in 35% of once-weekly patients and 51% of twice-weekly patients (P = .003). The incidence of grade 3/4 peripheral neuropathy was 8% in the once-weekly and 28% in the twice-weekly group (P < .001); 5% of patients in the once-weekly and 15% in the twice-weekly group discontinued therapy because of peripheral neuropathy (P < .001). This improvement in safety did not appear to affect efficacy. This study is registered at http://www.clinicaltrials.gov as NCT01063179.

    The combination of bortezomib-melphalan-prednisone (VMP) is a new standard of care for newly diagnosed multiple myeloma. This phase III study examined the efficacy of the four-drug combination of bortezomib-melphalan-prednisone-thalidomide (VMPT) followed by maintenance with bortezomib-thalidomide (VMPT-VT) compared with VMP treatment alone in untreated multiple myeloma patients who are ineligible for autologous stem-cell transplantation.. A total of 511 patients were randomly assigned to receive nine cycles of VMPT followed by continuous VT as maintenance, or nine cycles of VMP at the same doses with no additional therapy. The primary end point was progression-free survival.. The 3-year estimates of progression-free survival were 56% in patients receiving VMPT-VT and 41% in those receiving VMP (hazard ratio [HR], 0.67; 95% CI, 0.50 to 0.90; P = .008). At 3 years, the cumulative proportions of patients who did not go on to the next therapy were 72% with VMPT-VT and 60% with VMP (HR, 0.58; 95% CI, 0.50 to 0.90; P = .007). Complete response rates were 38% in the VMPT-VT group and 24% in the VMP group (P < .001). The 3-year overall survival was 89% with VMPT-VT and 87% with VMP (HR, 0.92; 95% CI, 0.53 to 1.60; P = .77). Grade 3 to 4 neutropenia (38% v 28%; P = .02), cardiologic events (10% v 5%; P = .04), and thromboembolic events (5% v 2%; P = .08) were more frequent among patients assigned to the VMPT-VT group than among those assigned to the VMP group; treatment-related deaths were 4% with VMPT-VT and 3% with VMP.. VMPT followed by VT as maintenance was superior to VMP alone in patients with multiple myeloma who are ineligible for autologous stem-cell transplantation.

The NK₁ receptor antagonist aprepitant does not alter the pharmacokinetics of high-dose melphalan chemotherapy in patients with multiple myeloma.
    British journal of clinical pharmacology, 2010, Volume: 70, Issue:6

    The objective of this investigation was to assess the effect of aprepitant on the pharmacokinetics of high-dose melphalan used as conditioning therapy before blood stem cell transplantation in multiple myeloma.. Aprepitant (125 mg) or placebo was administered 1 h before melphalan therapy (1 h infusion of 100 mg m⁻²). Eleven plasma samples were obtained over 8 h and melphalan was quantified using an LC/MS/MS method. Standard pharmacokinetic parameters were calculated and nonparametric testing was applied to assess the differences between aprepitant and placebo treatment.. Twenty patients received placebo and 10 patients aprepitant treatment. There were no differences observed for C(max) at the end of melphalan infusion (placebo 3431 ± 608 ng ml⁻¹ vs. aprepitant 3269 ± 660 ng ml⁻¹). In addition, AUC and terminal elimination half-life were not changed by aprepitant. Total clearance of melphalan was 304 ± 58 ml min⁻¹ m⁻² (placebo) which was not influenced by aprepitant (288 ± 78 ml min⁻¹ m⁻²).. The administration of the NK₁ receptor antagonist aprepitant 1 h before a high-dose chemotherapy does not influence the exposure and the elimination of melphalan. Therefore, oral administration of 125 mg aprepitant 1 h before melphalan infusion does not alter the disposition of intravenously administered melphalan.

EPO in combination with G-CSF improves mobilization effectiveness after chemotherapy with ifosfamide, epirubicin and etoposide and reduces costs during mobilization and transplantation of autologous hematopoietic progenitor cells.
    Bone marrow transplantation, 2009, Volume: 43, Issue:3

    A successful stem cell harvest is a prerequisite for peripheral blood SCT. We investigated the number of CD34(+) cells mobilized, the number of leukaphereses needed and the expenses of treatment for 28 patients with multiple myeloma randomly assigned to receive either G-CSF alone or G-CSF+EPO for stem cell mobilization after chemotherapy with ifosfamide, epirubicin and etoposide. All patients treated with G-CSF+EPO reached the threshold of 6 x 10(6) CD34(+) cells per kg body weight (kgbw), with a mean of 1.3 leukaphereses. On average 15.4 x 10(6) CD34(+) cells/kgbw were collected. In the G-CSF-alone group, the mean number of leukaphereses was 1.8, and 12.6 x 10(6) CD34(+) cells/kgbw were collected, and two patients failed the threshold. Overall costs per patient for mobilization and leukaphereses were 8339 euro (G-CSF+EPO) and 8842 euro (G-CSF). After transplantation, fewer blood transfusions (0.6 versus 1.3, P=0.05), fewer days on antibiotics (2.3 versus 6.1, P=0.02) and a shorter hospital stay (15.2 versus 17.8, P=0.06) were noted in the G-CSF+EPO group resulting in a 19.2% reduction of costs for each transplant (P=0.018). In summary, EPO improves the mobilization efficiency of G-CSF and so reduces costs of mobilization and SCT.

Thalidomide-dexamethasone compared with melphalan-prednisolone in elderly patients with multiple myeloma.
    Blood, 2009, Apr-09, Volume: 113, Issue:15

    We compared thalidomide-dexamethasone (TD) with melphalan-prednisolone (MP) in 289 elderly patients with multiple myeloma (MM). Patients received either thalidomide 200 mg plus dexamethasone 40 mg, days 1 to 4 and 15 to 18 on even cycles and days 1 to 4 on odd cycles, during a 28-day cycle or to melphalan 0.25 mg/kg and prednisolone 2 mg/kg orally on days 1 to 4 during a 28- to 42-day cycle. Patients achieving stable disease or better were randomly assigned to maintenance therapy with either thalidomide 100 mg daily and 3 MU interferon alpha-2b thrice weekly or to 3 MU interferon alpha-2b thrice weekly only. TD resulted in a higher proportion of complete and very good remissions (26% vs 13%; P= .006) and overall responses (68% vs 50%; P= .002) compared with MP. Time to progression (21.2 vs 29.1 months; P= .2), and progression-free survival was similar (16.7 vs 20.7 months; P= .1), but overall survival was significantly shorter in the TD group (41.5 vs 49.4 months; P= .024). Toxicity was higher with TD, particularly in patients older than 75 years with poor performance status. The study was registered at ClinicalTrials.gov as NCT00205751.

Oral integrity and salivary profile in myeloma patients undergoing high-dose therapy followed by autologous SCT.
    Bone marrow transplantation, 2009, Volume: 43, Issue:10

    The underlying mechanism of high-dose therapy (HDT)-related oral mucositis (OM) may be partly mediated by alterations in the normal salivary composition. This study evaluated salivary antioxidant and immunological capacities observed in myeloma patients suffering from HDT-related OM, and assessed potential contribution of these factors to OM development. Twenty-five consecutive myeloma patients treated with melphalan 200 mg/m(2) followed by autologous SCT were enrolled. Patients underwent a daily assessment for OM, and salivary samples were collected on days -3 and +7 of transplantation and analyzed for secretory IgA and antioxidant capacity. The degree of mucosal damage was assessed by measuring the salivary carbonyl and albumin (Alb) levels. OM, reported in 96% of patients, appeared to be most severe on 8 day after transplantation (range: +2 to +14). Clinical mucositis was associated with significant reduction in salivary secretory IgA (54%; P=0.05), and antioxidant activity, measured by total antioxidant status (40%; P=0.0004), antioxidant capacity (ImAnOx) (23%; P=0.002) and uric acid level (51%; P=0.006). The increase found in salivary Alb (119%; P=0.024) and carbonyl (28%; P=0.047) levels, indicates mucosal and oxidative damage, respectively. These salivary changes might enhance mucositis development and symptoms. Therapeutic interventions, enhancing antioxidative and immunological activities need to be investigated.

Bortezomib administered pre-auto-SCT and as maintenance therapy post transplant for multiple myeloma: a single institution phase II study.
    Bone marrow transplantation, 2009, Volume: 43, Issue:10

    The appropriate induction therapy before and the role of maintenance therapy after auto-SCT for patients with multiple myeloma remain areas of active investigation. We conducted a study in 40 patients with bortezomib given sequentially pre-auto-SCT and as maintenance therapy post auto-SCT. Pre-transplant bortezomib was administered for two cycles followed by high-dose melphalan 200 mg/m(2) with auto-SCT of G-CSF-mobilized PBMCs. Post transplant bortezomib was administered weekly for 5 out of 6 weeks for six cycles. No adverse effects were observed on stem cell mobilization or engraftment. An overall response rate of 83% with a CR+very good partial remission (VGPR) of 50% was observed with this approach. Three-year Kaplan-Meier estimates of disease-free survival and overall survival (OS) were 38.2 and 63.1%, respectively. Bortezomib reduced CD8(+) cytotoxic T cell and CD56(+) natural killer cell PBL subsets and was clinically associated with high rates of viral reactivation to varicella zoster.

A Phase II trial of autologous stem cell transplantation followed by mini-allogeneic stem cell transplantation for the treatment of multiple myeloma: an analysis of Eastern Cooperative Oncology Group ECOG E4A98 and E1A97.
    Biology of blood and marrow transplantation : journal of the American Society for Blood and Marrow Transplantation, 2009, Volume: 15, Issue:1

    Conventional allogeneic hematopoietic stem cell transplantation (HSCT) for multiple myeloma is associated with high transplantation-related mortality (TRM). Nonmyeloablative allogeneic transplantation (NST) uses the well-known graft-versus-myeloma (GVM) effect to eradicate minimal residual disease. The Eastern Cooperative Oncology Group conducted a Phase II trial of autologous HSCT followed by NST to provide maximal tumor cytoreduction to allow for a subsequent GVM effect. Patients received melphalan 200 mg/m(2) with autologous HSCT, followed by fludarabine 30 mg/m(2) in 5 daily doses and cyclophosphamide 1 g/m(2) in 2 daily doses with matched sibling donor NST. Graft-versus-host disease (GVHD) prophylaxis included cyclosporine and corticosteroids. The primary endpoints were TRM, graft failure, acute GVHD, progression-free survival (PFS), and overall survival (OS). Thirty-two patients were enrolled into the study; 23 patients completed both transplantations (72%). Best responses post-NST were 7 (30%) complete remission (CR), 11 (48%) partial remission (PR), 2 (9%) no response, and 3 (13%) not evaluable. Acute grade III-IV GVHD was observed in 4 patients (17%), and chronic GVHD was seen in 13 patients (57%; 7 limited, 6 extensive). Chronic GVHD resulted in the following responses: 3 (23%) CR, 1 continuing CR, and 6 (46%) PR. Two patients (8.7%) had early TRM. With a median follow up of 4.6 years, the median PFS was 3.6 years, and the 2-year OS was 78%. Our findings indicate that autologous HSCT followed by NST is feasible, with a low early TRM in a cooperative group setting. The overall response rate was 78%, including 30% CR, similar to other reports for autologous HSCT-NST. Because a plateau in PFS or OS was not observed with this treatment approach even in patients achieving CR, we suggest that future studies use posttransplantation maintenance therapy.

Bortezomib, low-dose intravenous melphalan, and dexamethasone for patients with relapsed multiple myeloma.
    British journal of haematology, 2009, Volume: 144, Issue:6

    This multicenter phase I/II study investigated the maximum tolerated dose (MTD), safety, and efficacy of low dose intravenous (IV) melphalan in combination with bortezomib for patients with relapsed multiple myeloma (MM). Patients received bortezomib 1.3 mg/m(2) on days 1, 4, 8, and 11 and escalating doses of IV melphalan (2.5-10.0 mg/m(2)) on day 2 of a 28-day cycle for a maximum of eight cycles. Dexamethasone 20 mg was added for progressive or stable disease. Fifty-three patients were enrolled. The MTD was defined at melphalan 7.5 mg/m(2) and bortezomib 1.3 mg/m(2). The overall response rate (ORR) was 68% (23% complete or near-complete responses [CR/nCR]) whilst at the MTD (n = 33) the ORR was 76% (34% CR/nCR). After median follow-up of 17 months, the median progression free survival was 10 months, rising to 12 months at the MTD (P < 0.05 vs. non-MTD regimens). The median overall survival was 28 months, but was not yet reached at the MTD. Grade 3/4 adverse events included thrombocytopenia (62%), neutropenia (57%), infection (21%), and neuropathy (15%). Bortezomib and low-dose IV melphalan combination therapy is a safe and highly effective regimen for patients with relapsed MM. These data suggest further investigation of this combination is warranted.

Single daily dose of intravenous busulfan and melphalan as a conditioning regimen for patients with multiple myeloma undergoing autologous stem cell transplantation: a phase II trial.
    Leukemia & lymphoma, 2009, Volume: 50, Issue:2

    We evaluated the toxicity and outcome of a conditioning regimen comprising intravenous (iv) busulfan (BU) and melphalan (MEL) in 55 patients (median age, 61 years; range, 34-71) with multiple myeloma (MM) undergoing autologous stem-cell transplantation (ASCT). In 49 patients, this was the first ASCT. At transplant, 3 patients were in complete response (CR), 8 in near CR (nCR) and 30 in partial response (PR). The conditioning regimen comprised ivBU (3.2 mg/kg in a single daily dose, days -5 to -3) and MEL (140 mg/m(2), day -2). Mucositis was the most frequent non-hematopoietic toxicity (47 patients). No patient developed sinusoidal occlusive syndrome. Febrile events were observed in 46 patients and were the cause of death in two (3.6%) transplant-related deaths. With a median follow-up of 15 months, 27 patients achieved CR/nCR (11 CR) and 21 a PR. The one-year actuarial overall and progression-free survival rates are 96% and 87%, respectively. This ivBU-containing regimen is associated with an acceptable toxicity and a high-response rate.

Bortezomib, ascorbic acid and melphalan (BAM) therapy for patients with newly diagnosed multiple myeloma: an effective and well-tolerated frontline regimen.
    European journal of haematology, 2009, Volume: 82, Issue:6

    We conducted a single-arm, multicentre phase 2 study to evaluate bortezomib, ascorbic acid and melphalan (BAM) for patients with newly diagnosed multiple myeloma (MM).. Induction consisted of up to eight 28-d cycles of bortezomib 1.0 mg/m(2) on days 1, 4, 8 and 11, plus oral ascorbic acid 1 g and oral melphalan 0.1 mg/kg on days 1-4, followed by maintenance bortezomib 1.3 mg/m(2) every 2 wk until progression.. Among 35 patients enrolled (median age 70 yr), responses occurred in 23/31 evaluable patients (74%) including five (16%) complete, three (10%) very good partial, six (19%) partial and nine (29%) minimal responses. Six patients (19%) had stable disease. Thus, disease control was achieved in 29 (94%) patients. Median times to first and best responses were 2 and 3 months (ranges 1-5 and 1-7), respectively. Median time to progression was 19 months and median overall survival has not been reached (range 2-23+ months). Grade 3 and 4 adverse events occurred in 17 and 5 patients, respectively; the most common were neutropenia, neuropathy and thrombocytopenia.. BAM is an efficacious, well-tolerated and steroid- and immunomodulatory drug (IMiD)-free frontline treatment regimen for MM patients.

The treatment of multiple myeloma using vincristine, carmustine, melphalan, cyclophosphamide, and prednisone (VBMCP) alternating with high-dose cyclophosphamide and alpha(2)beta interferon versus VBMCP: results of a phase III Eastern Cooperative Oncology
    Cancer, 2009, May-15, Volume: 115, Issue:10

    A randomized controlled trial tested the hypothesis that aggressive initial therapy using high-dose cyclophosphamide (HiCy) and alpha(2)beta interferon (IFN) may be superior to standard combination alkylating agent regimens in the treatment of newly diagnosed myeloma.. This Eastern Cooperative Oncology Group trial evaluated 268 previously untreated patients with active multiple myeloma randomized to vincristine, carmustine, melphalan, cyclophosphamide, and prednisone (VBMCP) or VBMCP plus HiCy and recombinant IFN.. The overall objective response was 62% in the VBMCP regimen and 68% in the VBMCP + HiCy + IFN group. The near complete response and complete response rates were 8.1% and 8.9%, respectively. Progression-free survival was 22.1 and 25.3 months, respectively. The median overall survival was 37.1 months for patients treated with VBMCP and 41.3 months for those treated with VBMCP + HiCy + IFN (P = .38). The 5-year overall survival rates were not significantly different between the 2 arms: 26.4% and 33%, respectively. Lethal toxicities occurred in 15 patients, including 10 from infection, but there was no significant difference in lethal toxicities between the 2 regimens.. The study showed no significant benefit with the addition of HiCy and IFN to VBMCP.

Consolidation therapy with low-dose thalidomide and prednisolone prolongs the survival of multiple myeloma patients undergoing a single autologous stem-cell transplantation procedure.
    Journal of clinical oncology : official journal of the American Society of Clinical Oncology, 2009, Apr-10, Volume: 27, Issue:11

    Thalidomide is effective in the treatment of newly diagnosed and relapsed/refractory multiple myeloma (MM). However, the role of thalidomide in the post-autologous stem cell transplantation (ASCT) context remains unclear. This study assessed whether the addition of thalidomide consolidation following ASCT would improve the durability of responses achieved and overall survival.. Between January 2002 and March 2005, 269 patients with newly diagnosed MM who achieved disease stabilization or better with conventional induction chemotherapy received a single high-dose melphalan conditioned ASCT. Post-ASCT, 129 patients were randomly assigned to receive indefinite prednisolone maintenance therapy (control group) and 114 to receive the same in addition to 12 months of thalidomide consolidation (thalidomide group). The primary study end points were progression-free survival (PFS) and overall survival (OS). The secondary end point was tolerability.. After a median follow-up of 3 years, the postrandomization 3-year PFS rates were 42% and 23% (P < .001; hazard ratio [HR], 0.5; 95% CI, 0.35 to 0.71) and the OS rates were 86% and 75% (P = .004; HR, 0.41; 95% CI, 0.22 to 0.76) in the thalidomide and control groups, respectively. There was no difference in survival between groups 12 months after disease progression (79% v 77%; P = .237). Neurological toxicities were more common in the thalidomide arm but there were no differences between arms for thromboembolic events.. Consolidation therapy with 12 months of thalidomide combined with prednisolone prolongs survival when used after a single high-dose therapy supported ASCT in patients with newly diagnosed MM. Furthermore, thalidomide consolidation therapy did not adversely impact on survival in the subsequent salvage setting.

Melphalan, prednisone, and lenalidomide for newly diagnosed myeloma: kinetics of neutropenia and thrombocytopenia and time-to-event results.
    Clinical lymphoma & myeloma, 2009, Volume: 9, Issue:2

    Initial analysis of the combination melphalan, prednisone, plus lenalidomide (MPR) showed significant antimyeloma activity in patients with untreated multiple myeloma, with neutropenia and thrombocytopenia as the most frequent side effects. This updated analysis reassessed the kinetics of neutropenia and thrombocytopenia as well as the safety and efficacy of MPR.. A total of 21 patients with newly diagnosed myeloma received melphalan 0.18 mg/kg on days 1-4, prednisone 2 mg/kg on days 1-4, and lenalidomide 10 mg daily on days 1-21 for nine 28-day cycles, followed by maintenance therapy with lenalidomide 10 mg daily on days 1-21.. Grade 3/4 neutropenia occurred in 52% of the patients, and granulocyte colonystimulating factor was administered in 43%. The mean neutrophil counts at the start of each MPR cycle, during nadir, and after 6 months of maintenance were 2.69 x 109/L, 1.43 x 109/L, and 2.11 x 109/L, respectively. Grade 3/4 thrombocytopenia occurred in 24% of the patients. Platelet transfusions were required by 1 patient (5%) with a platelet count of 16 x 109/L; however, no thrombocytopenia-associated bleeding was reported. The mean platelet counts at the start of each cycle, during nadir, and after 6 months of maintenance were 174 x 109/L, 121 x 109/L, and 158 x 109/L, respectively. Median follow-up was 29.6 months, median progression-free survival was 28.5 months, and 2-year overall survival was 91%.. MPR is a promising regimen with manageable hematologic toxicity.

Efficacy of melphalan and prednisone plus thalidomide in patients older than 75 years with newly diagnosed multiple myeloma: IFM 01/01 trial.
    Journal of clinical oncology : official journal of the American Society of Clinical Oncology, 2009, Aug-01, Volume: 27, Issue:22

    Until recently, melphalan and prednisone were the standards of care in elderly patients with multiple myeloma. The addition of thalidomide to this combination demonstrated a survival benefit for patients age 65 to 75 years. This randomized, placebo-controlled, phase III trial investigated the efficacy of melphalan and prednisone plus thalidomide in patients older than 75 years with newly diagnosed myeloma.. Between April 2002 and December 2006, 232 previously untreated patients with myeloma, age 75 years or older, were enrolled and 229 were randomly assigned to treatment. All patients received melphalan (0.2 mg/kg/d) plus prednisone (2 mg/kg/d) for 12 courses (day 1 to 4) every 6 weeks. Patients were randomly assigned to receive 100 mg/d of oral thalidomide (n = 113) or placebo (n = 116), continuously for 72 weeks. The primary end point was overall survival.. After a median follow-up of 47.5 months, overall survival was significantly longer in patients who received melphalan and prednisone plus thalidomide compared with those who received melphalan and prednisone plus placebo (median, 44.0 v 29.1 months; P = .028). Progression-free survival was significantly prolonged in the melphalan and prednisone plus thalidomide group (median, 24.1 v 18.5 months; P = .001). Two adverse events were significantly increased in the melphalan and prednisone plus thalidomide group: grade 2 to 4 peripheral neuropathy (20% v 5% in the melphalan and prednisone plus placebo group; P < .001) and grade 3 to 4 neutropenia (23% v 9%; P = .003).. This trial confirms the superiority of the combination melphalan and prednisone plus thalidomide over melphalan and prednisone alone for prolonging survival in very elderly patients with newly diagnosed myeloma. Toxicity was acceptable.

Rapid immune recovery and graft-versus-host disease-like engraftment syndrome following adoptive transfer of Costimulated autologous T cells.
    Clinical cancer research : an official journal of the American Association for Cancer Research, 2009, Jul-01, Volume: 15, Issue:13

    Previously, we showed that adoptive transfer of in vivo vaccine-primed and ex vivo (anti-CD3/anti-CD28) costimulated autologous T cells (ex-T) at day +12 after transplant increased CD4 and CD8 T-cell counts at day +42 and augmented vaccine-specific immune responses in patients with myeloma. Here, we investigated the safety and kinetics of T-cell recovery after infusing ex-T at day +2 after transplant.. In this phase I/II two-arm clinical trial, 50 patients with myeloma received autografts after high-dose melphalan followed by infusions of ex-T at day +2 after transplant. Patients also received pretransplant and posttransplant immunizations using a pneumococcal conjugate vaccine only (arm B; n = 24) or the pneumococcal conjugate vaccine plus an HLA-A2-restricted microltipeptide vaccine for HLA-A2(+) patients (arm A; n = 26).. The mean number of T cells infused was 4.26 x 10(10) (range, 1.59-5.0). At day 14 after transplant, the median CD3, CD4, and CD8 counts were 4,198, 1,545, and 2,858 cells/microL, respectively. Interleukin (IL)-6 and IL-15 levels increased early after transplant and IL-15 levels correlated significantly to day 14 T-cell counts. Robust vaccine-specific B- and T-cell responses were generated. T-cell infusions were well tolerated with no effect on hematopoietic recovery. Eight patients (16%) developed a T-cell "engraftment syndrome" characterized by diarrhea and fever that was clinically and histopathologically indistinguishable from grade 1 to 3 acute graft-versus-host disease (GVHD) of the gastrointestinal tract (seven patients) and/or grade 1 to 2 cutaneous GVHD (four patients).. Adoptive T-cell transfers achieve robust T-cell recovery early after transplant and induce moderate-to-severe autologous GVHD in a subset of patients.

Phase II study of thalidomide plus dexamethasone induction followed by tandem melphalan-based autotransplantation and thalidomide-plus-prednisone maintenance for untreated multiple myeloma: a southwest oncology group trial (S0204).
    Journal of clinical oncology : official journal of the American Society of Clinical Oncology, 2009, Jul-20, Volume: 27, Issue:21

    PURPOSE Thalidomide-dexamethasone (THAL-DEX) is standard induction therapy for multiple myeloma (MM). Tandem melphalan-based transplantations have yielded superior results to single transplantations. Phase II trial S0204 was designed to improve survival results reported for the predecessor, phase III trial S9321 by 50%. PATIENTS AND METHODS Newly diagnosed patients with MM were eligible for S0204 with THAL-DEX induction, tandem melphalan-based tandem transplantation, and THAL-prednisone maintenance. Results Of 143 eligible patients, 142 started induction, 73% completed first transplantation, 58% completed second transplantation, and 56% started maintenance. The quantity of stem cells required for two transplantations was reached in 88% of 111 patients undergoing collection, 74% of whom completed both transplantations. Partial response, very good partial remission, and complete response were documented after 12 months of maintenance therapy in 87%, 72%, and 22% of patients, respectively. During a median follow-up time of 37 months, 4-year estimates of event-free and overall survival were 50% and 64%, respectively. Survival outcomes were superior for International Staging System (ISS) stage 1 disease, when lactate dehydrogenase (LDH) levels were normal and a second transplantation was applied in a timely fashion. CONCLUSION Both overall survival (P = .0002) and event-free survival (P < .0001) were significantly improved with S0204 compared with S9321 when 121 and 363 patients, respectively, were matched on ISS stage and LDH.

VMP (Bortezomib, Melphalan, and Prednisone) is active and well tolerated in newly diagnosed patients with multiple myeloma with moderately impaired renal function, and results in reversal of renal impairment: cohort analysis of the phase III VISTA study.
    Journal of clinical oncology : official journal of the American Society of Clinical Oncology, 2009, Dec-20, Volume: 27, Issue:36

    PURPOSE To assess bortezomib plus melphalan and prednisone (VMP) and melphalan and prednisone (MP) in previously untreated patients with multiple myeloma (MM) with renal impairment enrolled on the phase III VISTA study, and to evaluate renal impairment reversibility. PATIENTS AND METHODS Patients received nine 6-week cycles of VMP (bortezomib 1.3 mg/m(2), melphalan 9 mg/m(2), prednisone 60 mg/m(2)) or MP. Patients with serum creatinine higher than 2 mg/dL were excluded. Results In the VMP/MP arms, 6%/4%, 27%/30%, and 67%/66% of patients had baseline glomerular filtration rate (GFR) of < or = 30, 31 to 50, and higher than 50 mL/min, respectively. Response rates were higher and time to progression (TTP) and overall survival (OS) longer with VMP versus MP across renal cohorts. Response rates with VMP and TTP in both arms did not appear significantly different between patients with GFR < or = 50 or higher than 50 mL/min; OS appeared somewhat longer in patients with normal renal function in both arms. Renal impairment reversal (baseline GFR < 50 improving to > 60 mL/min) was seen in 49 (44%) of 111 patients receiving VMP versus 40 (34%) of 116 patients receiving MP. By multivariate analysis, younger age (< 75 years; P = .006) and less severe impairment (GFR > or = 30 mL/min; P = .027) were associated with higher reversal rates. In addition, treatment with VMP approached significance (P = .07). In both arms, rates of grade 4 and 5 adverse events (AEs) and serious AEs appeared higher in patients with renal impairment; with VMP, rates of discontinuations/bortezomib dose reductions due to AEs did not appear affected. CONCLUSION VMP is a feasible, active, and well-tolerated treatment option for previously untreated patients with MM with moderate renal impairment, resulting in 44% renal impairment reversal.

Thalidomide maintenance following high-dose melphalan with autologous stem cell support in myeloma.
    Clinical lymphoma & myeloma, 2008, Volume: 8, Issue:3

    Recent experience with thalidomide maintenance after high-dose chemotherapy with autologous stem cell support has demonstrated improvement in progression-free survival (PFS) and overall survival (OS). We further explored the tolerability and efficacy of lower doses of maintenance thalidomide in this single-institution study.. Thirty-eight patients with myeloma were enrolled and treated with melphalan 200 mg/m(2) followed by autologous stem cell transplantation. Thalidomide 50 mg per day was started on day > or = 60 after recovery of blood counts and was escalated to a maximum dose of 200 mg per day. Responses were assessed at 2 months, 1 year, and 2 years after transplantation.. Of the 38 enrolled patients, 7 patients never received thalidomide. Among 31 patients receiving thalidomide, complete or very good partial responses were observed in 65% and 42% of patients at 1 and 2 years, respectively. Tolerability was a major issue, with only 17 patients completing 1 year of thalidomide. The goal of dosing 200 mg per day was achieved in just 17 of 31 patients, and the median tolerated thalidomide dose was 100 mg per day. Sensory neuropathy was the primary reason for dose modification and discontinuation. No thromboembolic events were observed. The median PFS was 20.8 months, and the median OS was > 60 months.. Thalidomide maintenance at a goal dose of 200 mg per day was not feasible in this population, with our data suggesting that 100 mg per day is a more reasonable maintenance dose.

Mobilization of peripheral blood stem cells in myeloma with either pegfilgrastim or filgrastim following chemotherapy.
    Haematologica, 2008, Volume: 93, Issue:11

    Quality and quantity of mobilized peripheral blood stem cells determine the safety of tandem autologous transplants in myeloma. Using the same mobilization chemotherapy with DT-PACE in two consecutive protocols, robustness of stem cell collection and rapidity of engraftment after transplantation were assessed. We employed either twice a day filgrastim versus two doses of pegfilgrastim. Advantages of pegfilgrastim were: (i) a higher percentage of patients collected 15x10(6)/kg in the first three days (p<0.001); (ii) the median number of CD34 cells/kg collected on day 1 was higher (p=0.004); (iii) the median number of growth factor injections was 2 versus 26 (p<0.0001); (iv) post-transplantation neutrophil recovery was faster after first and second transplant (p<0.001) and (v) platelet recovery was faster after first transplant (when less stem cells were infused) (p=0.01). Pegfilgrastim may be considered the standard of care for stem cell mobilization.

Bortezomib plus melphalan and prednisone for initial treatment of multiple myeloma.
    The New England journal of medicine, 2008, Aug-28, Volume: 359, Issue:9

    The standard treatment for patients with multiple myeloma who are not candidates for high-dose therapy is melphalan and prednisone. This phase 3 study compared the use of melphalan and prednisone with or without bortezomib in previously untreated patients with multiple myeloma who were ineligible for high-dose therapy.. We randomly assigned 682 patients to receive nine 6-week cycles of melphalan (at a dose of 9 mg per square meter of body-surface area) and prednisone (at a dose of 60 mg per square meter) on days 1 to 4, either alone or with bortezomib (at a dose of 1.3 mg per square meter) on days 1, 4, 8, 11, 22, 25, 29, and 32 during cycles 1 to 4 and on days 1, 8, 22, and 29 during cycles 5 to 9. The primary end point was the time to disease progression.. The time to progression among patients receiving bortezomib plus melphalan-prednisone (bortezomib group) was 24.0 months, as compared with 16.6 months among those receiving melphalan-prednisone alone (control group) (hazard ratio for the bortezomib group, 0.48; P<0.001). The proportions of patients with a partial response or better were 71% in the bortezomib group and 35% in the control group; complete-response rates were 30% and 4%, respectively (P<0.001). The median duration of the response was 19.9 months in the bortezomib group and 13.1 months in the control group. The hazard ratio for overall survival was 0.61 for the bortezomib group (P=0.008). Adverse events were consistent with established profiles of toxic events associated with bortezomib and melphalan-prednisone. Grade 3 events occurred in a higher proportion of patients in the bortezomib group than in the control group (53% vs. 44%, P=0.02), but there were no significant differences in grade 4 events (28% and 27%, respectively) or treatment-related deaths (1% and 2%).. Bortezomib plus melphalan-prednisone was superior to melphalan-prednisone alone in patients with newly diagnosed myeloma who were ineligible for high-dose therapy.

The combination of bortezomib, melphalan, dexamethasone and intermittent thalidomide is an effective regimen for relapsed/refractory myeloma and is associated with improvement of abnormal bone metabolism and angiogenesis.
    Leukemia, 2008, Volume: 22, Issue:12

    This phase 2 study aimed to determine the efficacy and safety of the combination of bortezomib, melphalan, dexamethasone and intermittent thalidomide (VMDT) and its effect on bone remodeling and angiogenesis in relapsed/refractory myeloma. Bortezomib (1.0 mg/m(2)) was given on days 1, 4, 8, 11, oral melphalan (0.15 mg/kg) on days 1-4, whereas thalidomide (100 mg per day) and dexamethasone (12 mg/m(2)) were administered on days 1-4 and 17-20 of a 28-day cycle, for four cycles. Patients without disease progression continued for up to eight cycles. VMDT effect on bone remodeling was evaluated by measuring osteoclast regulators (soluble receptor activator of nuclear factor-kappa B ligand/osteoprotegerin ratio, osteopontin, macrophage inflammatory protein-1alpha), dickkopf-1 protein, bone resorption and formation markers, whereas its effect on angiogenesis was assessed by measuring serum vascular endothelial growth factor, angiogenin, angiopoietin-2 and basic fibroblast growth factor, after four cycles and at the study end. A total of 62 patients were enrolled. The overall response rate was 66%: CR 13%, vgPR 27% and PR 26%. Median time to response was 35 days and median time to progression was 9.3 months. Common adverse events included cytopenias, peripheral neuropathy and infections. No patient experienced deep-vein thrombosis. VMDT reduced angiogenic cytokines, osteoclast regulators, dickkopf-1 and bone resorption. We conclude that VMDT with intermittent thalidomide is an active and well-tolerated regimen for relapsed/refractory myeloma, affecting abnormal bone remodeling and angiogenesis.

Update on recent developments for patients with newly diagnosed multiple myeloma.
    Annals of the New York Academy of Sciences, 2008, Volume: 1138

    Recent studies have demonstrated that novel therapeutic combinations are challenging melphalan and prednisone (MP) as the standard of care in elderly patients with multiple myeloma. Combination regimens containing bortezomib or thalidomide can achieve response rates, especially complete response rates, which are superior to those seen with standard MP alone, and offer new possibilities for this patient population.

Arsenic trioxide with ascorbic acid and high-dose melphalan: results of a phase II randomized trial.
    Biology of blood and marrow transplantation : journal of the American Society for Blood and Marrow Transplantation, 2008, Volume: 14, Issue:12

    Arsenic trioxide (ATO) is synergistic with ascorbic acid (AA) and melphalan against myeloma both in vitro and in vivo. The aim of this randomized phase II trial was to determine the safety and efficacy of a combination of ATO, melphalan, and AA as preparative regimen in 48 patients undergoing autologous hematopoietic stem cell transplantation (ASCT) for multiple myeloma (MM). Forty-eight patients received melphalan 200 mg/m2 i.v. over 2 days and AA 1000 mg i.v. over 7 days in 3 treatment arms: no ATO (arm 1), ATO 0.15 mg/kg i.v. x 7 days (arm 2), and ATO 0.25 mg/kg i.v. x 7 days (arm 3). No dose-limiting toxicity, engraftment failure, or nonrelapse mortality (NRM) was seen in the first 100 days post-ASCT. Complete responses (CR) were seen in 12 of 48 patients (25%), with an overall response rate (ORR = CR + PR) of 85%. Median progression-free survival (PFS) was 25 months; median overall survival (OS) has not yet been reached. There was no significant difference in CR, PFS, or OS among the 3 treatment arms, and no adverse effect of ATO on melphalan pharmacokinetics. Addition of ATO + AA to high-dose melphalan is safe and well tolerated as a preparative regimen for MM.

Response to chemotherapy and tandem autologous transplantation of multiple myeloma patients and GSTP1 and TYMS polymorphisms.
    Leukemia research, 2008, Volume: 32, Issue:1

    This study examines the response to dexamethasone-doxorubicin-vincristine (DAV) therapy, followed by conditioning regimen and autologous stem cells transplantation (ASCT) in patients with multiple myeloma in relation with the presence of polymorphisms in genes involved in drug metabolism (GSTP1) and DNA synthesis (TYMS). GSTP1 G313G genotype (OR=5.49; 95% CI, 1.3-22.5, p=0.02) and TYMS A227A genotype (OR=3.41; 95% CI, 1.3-8.9, p=0.01) resulted significantly associated with a poor response following chemotherapy and the risk increased for the combined genotype (OR=13.54; 95% CI, 2.0-91.3, p=0.01). TYMS T157T genotype was significantly associated with a poor response after ASCT (OR=4.60; 95% CI, 1.2-16.9, p=0.02). Pre-therapeutic individual determination of the GSTP1 and TYMS polymorphisms could help in choosing the most appropriate protocol.

Cyclophosphamide plus dexamethasone is an efficient initial treatment before high-dose melphalan and autologous stem cell transplantation in patients with newly diagnosed multiple myeloma: results of a randomized comparison with vincristine, doxorubicin,
    Cancer, 2008, Jan-01, Volume: 112, Issue:1

    Today, intensive therapy that includes high-dose melphalan with autologous stem cell transplantation (ASCT) is considered standard therapy in younger patients with newly diagnosed myeloma. When the current trial was initiated, combined vincristine, doxorubicin, and dexamethasone (VAD) was the most commonly used induction therapy before ASCT and yielded rapid major responses without interfering with stem cell harvest. However, the administration of VAD demands a central venous access, and well-described toxicities are associated with the therapy. This randomized trial, which was initiated in 2001 by the Nordic Myeloma Study Group, was an attempt to bring a larger portion of patients to ASCT more quickly.. Patients were randomized to receive either 3 cycles of VAD or 2 courses of cyclophosphamide plus dexamethasone (Cy-Dex) (cyclophosphamide at a dose of 1000 mg/m(2) on Day 1 and dexamethasone at a dose of 40 mg per day on Days 1-4 and 9-12, repeated on Day 22) as initial therapy followed by stem cell mobilization, harvest, and finally ASCT.. No significant difference was observed in the proportion of patients undergoing ASCT (VAD [86%] vs Cy-Dex [87%]). During the first 4 months after the initiation of therapy, the mortality rates were 5.8% for VAD and 1.9% for Cy-Dex (P = .08). The response rates after ASCT were comparable (partial response or better: VAD: 80% vs Cy-Dex: 81%). In both groups, the median event-free survival was 29 months, and the overall survival rate at 3 years was 75%.. The current results indicated that Cy-Dex before ASCT has efficacy comparable to that of VAD. It also demonstrated that a short course of alkylator therapy using cyclophosphamide does not affect stem cell harvest or transplantation.

Bortezomib plus melphalan and prednisone in elderly untreated patients with multiple myeloma: updated time-to-events results and prognostic factors for time to progression.
    Haematologica, 2008, Volume: 93, Issue:4

    New treatment options offering enhanced activity in elderly, newly diagnosed patients with multiple myeloma are required. One strategy is to combine melphalan and prednisone with novel agents. We previously reported an 89% response rate, including 32% complete responses and 11% near complete responses, in our phase 1/2 study of bortezomib plus melphalan and prednisone (VMP) in 60 newly diagnosed multiple myeloma patients with a median age of 75 years. Here, we report updated time-to-events data and the impact of poor prognosis factors on outcome.. Updated analyses of time to biochemical progression and overall survival with VMP were conducted, and compared with those of historical controls treated with melphalan and prednisone. A univariate analysis was performed to evaluate the influence of known prognostic factors on the time to progression.. After a median follow-up of 26 months, the median time to progression with VMP was 27.2 months, compared with 20.0 months with melphalan plus prednisone. The median overall survival with VMP was not reached versus 26 months with melphalan and prednisone; the survival rate at 38 months was 85% versus 38%, respectively. Time to progression was not significantly affected by elevated beta(2)-microglobulin or lactate dehydrogenase levels, advanced age, or cytogenetic abnormalities, but was shorter in patients with albumin < 3 g/dL, Karnofsky performance status < or =70%, bone marrow plasma cell infiltration > or =40%, and, particularly, high plasma cell proliferative activity (> or = 2.5% S-phase cells).. VMP is highly active and well tolerated in elderly patients with newly diagnosed multiple myeloma, with 85% of patients alive at 3 years. Moreover, VMP may overcome the poor prognostic impact of various factors, particularly cytogenetic abnormalities.

Safety and efficacy of bortezomib and melphalan combination in patients with relapsed or refractory multiple myeloma: updated results of a phase 1/2 study after longer follow-up.
    Annals of hematology, 2008, Volume: 87, Issue:8

    Bortezomib synergizes with melphalan in preclinical and early clinical studies. Updated data from our phase 1/2 study assessing the safety and efficacy of bortezomib plus melphalan in relapsed/refractory multiple myeloma (MM) are presented. Bortezomib (0.7, 1.0, or 1.3 mg/m(2)) on days 1, 4, 8, and 11 and oral melphalan (0.025-0.25 mg/kg) on days 1-4 of a 28-day cycle were administered. Hematologic toxicities defined the maximum tolerated dose as bortezomib 1.0 mg/m(2) and melphalan 0.10 mg/kg. Because dose-limiting toxicities were attributed to the more myelosuppressive melphalan, cohorts 9 and 10 with higher bortezomib (1.3 mg/m(2)) and lower melphalan (0.025 and 0.10 mg/kg) doses were added. Responses occurred in 32/46 (70%) evaluable patients: two complete (4%), five near-complete (11%), 16 partial (35%), and nine minimal (20%). Complete and near-complete responses were observed only with higher bortezomib doses. Response rates were similar in patients with prior melphalan or bortezomib. Median progression-free survival was 9 months (range, 1-24), and overall survival was 32 months (range, 1-54). The most common grade 3/4 hematologic adverse events (AEs) were neutropenia (31%/0%), thrombocytopenia (25%/2%), and anemia (13%/0%). Grade 4 tumor lysis syndrome was reported in one patient. Fewer grade 3/4 hematologic AEs were reported in cohorts 9 and 10 than in cohorts receiving lower bortezomib and higher melphalan doses. In conclusion, bortezomib plus melphalan is a steroid- and immunomodulatory drug-free regimen that may provide a treatment alternative for elderly patients and patients with significant comorbidity.

Oral melphalan, prednisone, and thalidomide in elderly patients with multiple myeloma: updated results of a randomized controlled trial.
    Blood, 2008, Oct-15, Volume: 112, Issue:8

    The initial analysis of the oral combination melphalan, prednisone, and thalidomide (MPT) in newly diagnosed patients with myeloma showed significantly higher response rate and longer progression-free survival (PFS) than did the standard melphalan and prednisone (MP) combination and suggested a survival advantage. In this updated analysis, efficacy and safety end points were updated. Patients were randomly assigned to receive oral MPT or MP alone. Updated analysis was by intention to treat and included PFS, overall survival (OS), and survival after progression. After a median follow-up of 38.1 months, the median PFS was 21.8 months for MPT and 14.5 months for MP (P = .004). The median OS was 45.0 months for MPT and 47.6 months for MP (P = .79). In different patient subgroups, MPT improved PFS irrespective of age, serum concentrations of beta(2)-microglobulin, or high International Staging System. Thalidomide or bortezomib administration as salvage regimens significantly improved survival after progression in the MP group (P = .002) but not in the MPT group (P = .34). These data confirm activity of MPT for PFS but failed to show any survival advantage. New agents in the management of relapsed disease could explain this finding. The study is registered at www.clinicaltrials.gov as #NCT00232934.

Bortezomib, melphalan, prednisone, and thalidomide for relapsed multiple myeloma.
    Blood, 2007, Apr-01, Volume: 109, Issue:7

    In multiple myeloma (MM), the addition of thalidomide or bortezomib to the standard oral melphalan/prednisone combination significantly increased response rate and event-free survival. In this multicenter phase 1/2 trial, dosing, safety, and efficacy of the 4-drug combination, bortezomib, melphalan, prednisone, and thalidomide (VMPT) was determined. Bortezomib was administered at 3 dose levels (1.0 mg/m2, 1.3 mg/m2, or 1.6 mg/m2) on days 1, 4, 15, and 22; melphalan was given at a dose of 6 mg/m2 on days 1 through 5 and prednisone at 60 mg/m2 on days 1 through 5. Thalidomide was delivered at 50 mg on days 1 through 35. Each course was repeated every 35 days. The maximum tolerated dose of bortezomib was 1.3 mg/m2. Thirty patients with relapsed or refractory MM were enrolled; 20 patients (67%) achieved a partial response (PR) including 13 patients (43%) who achieved at least a very good PR. Among 14 patients who received VMPT as second-line treatment, the PR rate was 79% and the immunofixation-negative complete response rate 36%. The 1-year progression-free survival was 61%, and the 1-year survival from study entry was 84%. Grade 3 nonhematologic adverse events included infections (5 patients), fatigue (1), vasculitis (1), and peripheral neuropathy (2); no grade 4 toxicities were recorded. Initial results showed that VMPT is an effective salvage therapy with a very high proportion of responses. The incidence of neurotoxicities was unexpectedly low.

Abnormalities of chromosome 1p/q are highly associated with chromosome 13/13q deletions and are an adverse prognostic factor for the outcome of high-dose chemotherapy in patients with multiple myeloma.
    British journal of haematology, 2007, Volume: 136, Issue:4

    The prognostic value of chromosomal abnormalities was studied in untreated multiple myeloma patients who were registered into a prospective randomised multicentre phase 3 study for intensified treatment (HOVON24). A total of 453 patients aged less than 66 years with stage II and III A/B disease were registered in the clinical study. Cytogenetic analysis was introduced as a standard diagnostic assay in 1998. It was performed at diagnosis in 160 patients and was successful in 137/160 patients (86%). An abnormal karyotype was observed in 53/137 (39%) of the patients. Abnormalities of chromosome 1p and 1q were found in 19 (36% of patients with an abnormal karyotype) and 21 patients (40%). There was a strong association between chromosome 1p and/or 1q abnormalities and deletion of chromosome 13 or 13q (n = 27, P < 0.001). Patients with karyotypic abnormalities had a significantly shorter overall survival (OS) than patients with normal karyotypes. Complex abnormalities, hypodiploidy, chromosome 1p abnormalities, chromosome 1q abnormalities, and chromosome 13 abnormalities were associated with inferior OS on univariate analysis, as well as after adjustment for other prognostic factors. In conclusion, chromosome 13 abnormalities and chromosome 1p and/or 1q abnormalities were highly associated, and are risk factors for poor outcome after intensive therapy in multiple myeloma.

A randomised comparison of melphalan with prednisone or dexamethasone as induction therapy and dexamethasone or observation as maintenance therapy in multiple myeloma: NCIC CTG MY.7.
    British journal of haematology, 2007, Volume: 136, Issue:2

    The effectiveness of melphalan plus dexamethasone (M-Dex) with melphalan plus prednisone (MP) as induction therapy and dexamethasone with observation as maintenance therapy was compared in 585 older patients with multiple myeloma. Randomization to the M-Dex arm was stopped as a result of an analysis performed which met a predetermined event-related criterion. Of 466 patients randomised to MP or M-Dex, no differences were detected in the respective median progression-free survivals (PFS) [1.8 vs. 1.9 years; Hazard Ratio (HR) = 0.88, 95% CI 0.72-1.07; P = 0.2] or overall survivals (OS) (2.5 vs. 2.7 years; HR = 0.91, 95% CI 0.74-1.11; P = 0.3). Of the initial 585 patients, 292 remained evaluable for maintenance therapy. Patients randomised to maintenance dexamethasone had a superior median PFS (2.8 years vs. 2.1 years; HR = 0.61, 95% CI 0.47-0.79; P = 0.0002). No difference in median OS was detected (4.1 years vs. 3.8 years; HR = 0.88, 95% CI 0.65-1.18; P = 0.4). The maintenance therapy results were robust when analysed by using two additional methodologies. Dexamethasone did not improve clinical outcome when combined with melphalan during induction; maintenance dexamethasone improved PFS, but this did not translate into a detectable survival advantage.

Autologous stem cell transplantation is safe and feasible in elderly patients with multiple myeloma.
    Bone marrow transplantation, 2007, Volume: 39, Issue:5

    Several clinical trials have shown the superiority of autologous stem cell transplantation over conventional dose therapy for patients with multiple myeloma. This treatment, however, is limited to younger patients (<65 years) owing to concerns about toxicity and treatment-related mortality (TRM) in older patients. We treated 26 elderly myeloma patients (>70 years), who received a preparative regimen of melphalan 200 mg/m2 (19 patients), melphalan 180 mg/m2 (six patients) or melphalan 140 mg/m2 (one patient). Twenty-two of the 26 patients were alive after a median follow-up of 25 months (range=8-74). Responses (complete+partial response) were seen in 20 patients (77%), five (19%) of which were complete responses. Median PFS was 24 months, whereas median OS has not been reached. Cumulative incidence of 100-day TRM was 0%. Three-year PFS and OS were 39% (range=16-61) and 65% (range=35-83), respectively. A low serum albumin (<3.5 g/dl) was associated with a shorter PFS (P=0.02). Patients with relapsed disease at transplant, and an interval of >12 months between diagnosis and autotransplant, had a shorter OS (P=0.0004 and 0.04). HDT and autologous transplant is safe and feasible in elderly myeloma patients.

Prospective, randomized study of single compared with double autologous stem-cell transplantation for multiple myeloma: Bologna 96 clinical study.
    Journal of clinical oncology : official journal of the American Society of Clinical Oncology, 2007, Jun-10, Volume: 25, Issue:17

    We performed a prospective, randomized study of single (arm A) versus double (arm B) autologous stem-cell transplantation (ASCT) for younger patients with newly diagnosed multiple myeloma (MM).. A total of 321 patients were enrolled onto the study and were randomly assigned to receive either a single course of high-dose melphalan at 200 mg/m2 (arm A) or melphalan at 200 mg/m2 followed, after 3 to 6 months, by melphalan at 120 mg/m2 and busulfan at 12 mg/kilogram (arm B).. As compared with assignment to the single-transplantation group (n = 163 patients), random assignment to receive double ASCT (n = 158 patients) significantly increased the probability to attain at least a near complete response (nCR; 33% v 47%, respectively; P = .008), prolonged relapse-free survival (RFS) duration of 18 months (median, 24 v 42 months, respectively; P < .001), and significantly extended event-free survival (EFS; median, 23 v 35 months, respectively; P = .001). Administration of a second transplantation and of novel agents for treating sequential relapses in up to 50% of patients randomly assigned to receive a single ASCT likely contributed to prolong the survival duration of the whole group, whose 7-year rate (46%) was similar to that of the double-transplantation group (43%; P = .90). Transplantation-related mortality was 3% in arm A and 4% in arm B (P = .70).. In comparison with a single ASCT as up-front therapy for newly diagnosed MM, double ASCT effected superior CR or nCR rate, RFS, and EFS, but failed to significantly prolong overall survival. Benefits offered by double ASCT were particularly evident among patients who failed at least nCR after one autotransplantation.

Reversibility of renal failure in newly diagnosed multiple myeloma patients treated with high dose dexamethasone-containing regimens and the impact of novel agents.
    Haematologica, 2007, Volume: 92, Issue:4

    The impact of high dose dexamethasone containing regimens with or without the novel agents thalidomide and bortezomib on the reversal of renal failure (RF) was evaluated in 41 consecutive newly diagnosed patients with multiple myeloma (MM) treated in a single institution. RF was reversed in 73% of all patients within a median of 1.9 months. In patients treated with dexamethasone and novel agents (thalidomide and/or bortezomib) the reversibility rate was 80% within a median of 0.8 months. Severe RF and significant Bence Jones proteinuria were associated with a lower probability of RF reversal. Patients who responded to treatment achieved RF reversal more often than in those who did not (85% versus 56%, p=0.046). In conclusion, RF is reversible in the majority of newly diagnosed MM patients treated with high-dose dexamethasone containing regimens. The addition of novel agents induces a more rapid RF reversal.

Bortezomib in combination with thalidomide-dexamethasone for previously untreated multiple myeloma.
    Hematology (Amsterdam, Netherlands), 2007, Volume: 12, Issue:3

    In a previous trial among 137 previously untreated patients with multiple myeloma, the combination of thalidomide-dexamethasone induced remission in 66% of patients, including complete remission in 13%. In an attempt to induce more frequent remissions, we added bortezomib to this program. Between 7/03 and 3/06, 38 newly diagnosed patients with multiple myeloma received at least one, but no more than 3, courses of bortezomib in a dose of 1.3 mg/m(2) IV x 4; dexamethasone 20 mg/m(2) PO for 4 days beginning on days 1, 9, 17; thalidomide 100 mg PO daily increasing to a maximum of 200 mg. There was rapid onset of remission in 33 patients (87%) including 6 patients with complete remission (16%). Most side effects were preventable, but otherwise were usually mild and reversible. After a median of 4 months, 25 eligible patients received intensive therapy with high-dose melphalan supported by autologous blood stem cells, so that the myeloma was in complete remission in 14 patients (37% of all patients). The combination of bortezomib-thalidomide-dexamethasone was a highly effective primary treatment for newly diagnosed patients with multiple myeloma.

Incorporating bortezomib into upfront treatment for multiple myeloma: early results of total therapy 3.
    British journal of haematology, 2007, Volume: 138, Issue:2

    Total therapy 3 incorporated bortezomib into a melphalan-based tandem transplant regimen for 303 newly diagnosed patients with myeloma. Induction chemotherapy prior to and consolidation chemotherapy after transplants each consisted of two cycles of VTD-PACE (bortezomib, thalidomide, dexamethasone and 4-d continuous infusions of cis-platin, doxorubicin, cyclophosphamide, etoposide); 3-year maintenance comprised monthly cycles of VTD in the first and TD in the remaining years. The median age was 59 years (age >64 years, 28%). A minimum of 20 x 10(6) CD34 cells/kg was collected in 87% of patients; 83% completed both transplants, and only 5% suffered a treatment-related death. At 24 months, 83% had achieved near-complete remission, which was sustained in 88% at 2 years from its onset. With a median follow-up of 20 months, 2-year estimates of event-free and overall survival were 84% and 86% respectively. The 44 patients who experienced an event more often had a high-risk gene array profile, cytogenetic abnormalities and indicators of high lactate dehydrogenase, beta-2-microglobulin, creatinine and International Staging System stage. Toxicities of grade > 2 included thrombo-embolic events in 27% and peripheral neuropathy in 12%. Results of this phase-2 study demonstrated that bortezomib could be safely combined with multi-agent chemotherapy, effecting near-complete remission status and 2-year survival rates in more than 80% of patients.

Intermediate-dose melphalan compared with myeloablative treatment in multiple myeloma: long-term follow-up of the Dutch Cooperative Group HOVON 24 trial.
    Haematologica, 2007, Volume: 92, Issue:7

    The Dutch-Belgian HOVON group performed a randomized phase 3 trial to compare single non-myeloablative intensive treatment with double, intensive treatment in previously untreated patients with multiple myeloma (MM).. Three hundred and three patients with stage II/III MM were randomized after VAD induction chemotherapy to receive two cycles of non-myeloablative intermediate-dose melphalan (70 mg/m2) (single treatment) or the same regimen followed by cyclophosphamide 120 mg/kg iv plus total body irradiation (TBI) 9 Gy and autologous stem cell transplantation (double, intensive treatment). In both treatment arms interferon .IIa was given as maintenance until relapse/progression.. A significantly higher proportion of patients achieved a complete remission (CR) on protocol treatment with double, intensive therapy (32 % vs 13 %, p<0.001). Double treatment produced better outcome in terms of event-free survival (median 22 vs 21 months, 28% vs 14% at 4 years and 15% vs 7% at 6 years after randomization; logrank p=0.013; univariate HR 0.74, 95% CI, 0.58-0.94), progression-free survival (median 27 vs 24 months, 33% vs 16% at 4 years, and 17% vs 9% at 6 years after randomization; logrank p=0.006; HR=0.71, 95% CI 0.56-0.91), but not overall survival (median 50 vs 55 months, 52% vs 56% at 4 years and 39% vs 36% at 6 years after randomization; logrank p=0.51; HR=1.10, 95% CI 0.83-1.46). The achievement of a CR had a favorable prognostic impact on event-free survival (HR=0.60 , 95% CI=0.44 -0.82 , p=0.001) and progression-free survival (HR=0.62 , 95% CI=0.45 -0.84, p=0.002).. Double, intensive treatment resulted in a better CR rate, event-free survival and progression-free survival but not overall survival compared to single non-myeloablative treatment in previously untreated patients with multiple myeloma.

Melphalan, prednisone, and lenalidomide treatment for newly diagnosed myeloma: a report from the GIMEMA--Italian Multiple Myeloma Network.
    Journal of clinical oncology : official journal of the American Society of Clinical Oncology, 2007, Oct-01, Volume: 25, Issue:28

    Lenalidomide has shown significant antimyeloma activity in clinical studies. Oral melphalan, prednisone, and thalidomide have been regarded as the standard of care in elderly multiple myeloma patients. We assessed dosing, efficacy, and safety of melphalan, prednisone, and lenalidomide (MPR) in newly diagnosed elderly myeloma patients.. Oral melphalan was administered in doses ranging from 0.18 to 0.25 mg/kg on days 1 to 4, prednisone at a 2-mg/kg dose on days 1 to 4, and lenalidomide at doses ranging from 5 to 10 mg on days 1 to 21, every 28 days for nine cycles, followed by maintenance therapy with lenalidomide alone. Aspirin was given as a prophylaxis for thrombosis.. Fifty-four patients were enrolled and evaluated after completing the assigned treatment schedule. The maximum tolerated dose was defined as 0.18 mg/kg melphalan and 10 mg lenalidomide. With these doses, 81% of patients achieved at least a partial response, 47.6% achieved a very good partial response, and 23.8% achieved a complete immunofixation-negative response. In all patients, 1-year event-free and overall survival rates were 92% and 100%, respectively. At the maximum tolerated dose, grade 3 adverse events included neutropenia (38.1%), thrombocytopenia (14.2%), febrile neutropenia (9.5%), vasculitis (9.5%), and thromboembolism (4.8%); grade 4 adverse events were neutropenia (14.2%) and thrombocytopenia (9.5%).. Oral MPR therapy is a promising first-line treatment for elderly myeloma patients. Hematologic adverse events were frequent but manageable. A low incidence of nonhematologic adverse events was noted. Aspirin appears to provide adequate antithrombosis prophylaxis.

Melphalan and prednisone plus thalidomide versus melphalan and prednisone alone or reduced-intensity autologous stem cell transplantation in elderly patients with multiple myeloma (IFM 99-06): a randomised trial.
    Lancet (London, England), 2007, Oct-06, Volume: 370, Issue:9594

    In multiple myeloma, combination chemotherapy with melphalan plus prednisone is still regarded as the standard of care in elderly patients. We assessed whether the addition of thalidomide to this combination, or reduced-intensity stem cell transplantation, would improve survival.. Between May 22, 2000, and Aug 8, 2005, 447 previously untreated patients with multiple myeloma, who were aged between 65 and 75 years, were randomly assigned to receive either melphalan and prednisone (MP; n=196), melphalan and prednisone plus thalidomide (MPT; n=125), or reduced-intensity stem cell transplantation using melphalan 100 mg/m2 (MEL100; n=126). The primary endpoint was overall survival. Analysis was by intention to treat. This trial is registered with ClinicalTrials.gov, number NCT00367185.. After a median follow-up of 51.5 months (IQR 34.4-63.2), median overall survival times were 33.2 months (13.8-54.8) for MP, 51.6 months (26.6-not reached) for MPT, and 38.3 months (13.0-61.6) for MEL100. The MPT regimen was associated with a significantly better overall survival than was the MP regimen (hazard ratio 0.59, 95% CI 0.46-0.81, p=0.0006) or MEL100 regimen (0.69, 0.49-0.96, p=0.027). No difference was seen for MEL100 versus MP (0.86, 0.65-1.15, p=0.32).. The results of our trial provide strong evidence to indicate that the use of thalidomide in combination with melphalan and prednisone should, at present, be the reference treatment for previously untreated elderly patients with multiple myeloma.

Veno-occlusive disease of the liver after high-dose cytoreductive therapy with busulfan and melphalan for autologous blood stem cell transplantation in multiple myeloma patients.
    Biology of blood and marrow transplantation : journal of the American Society for Blood and Marrow Transplantation, 2007, Volume: 13, Issue:12

    Veno-occlusive disease of the liver (VOD) is a potentially severe complication of high-dose cytoreductive therapy (HDT) used for stem cell transplantation (SCT). This complication is uncommon after HDT for autologous SCT (ASCT) in patients with multiple myeloma (MM). The Spanish Myeloma Group/PETHEMA conducted a study (MM2000) for patients with newly diagnosed MM consisting of induction with alternating VBMCP/VBAD chemotherapy followed by intensification with busulfan/melphalan (Bu/MEL) with a second high-dose therapy procedure in patients not achieving at least near-complete remission with the first procedure. After 2 years of the trial, a number of episodes resembling classical VOD but with a late onset were recognized. Consequently, the protocol was modified, and Bu/MEL was replaced by melphalan 200 mg/m(2) (MEL-200). Three years later, after a total of 734 patients had undergone first autologous SCT, the incidence and characteristics of VOD episodes were analyzed in the whole series. Nineteen cases of VOD (8%) were observed among the first 240 patients receiving Bu/MEL, whereas only 2 (0.4%) were observed among the 494 patients treated with MEL-200 (P < .0001). VOD manifestations in the Bu/MEL group appeared at a median of 29 days (range, 3-57 days) after ASCT. Mortality directly attributable to VOD was 2% in the Bu/MEL group and 0.2% in the MEL-200 group (P = .026). This high incidence of severe VOD probably had a multifactorial origin (busulfan followed by melphalan and previous use of BCNU). This observation should be kept in mind when designing future trials for the treatment of MM.

Melphalan-induced DNA damage in vitro as a predictor for clinical outcome in multiple myeloma.
    Haematologica, 2007, Volume: 92, Issue:11

    As new therapeutic options for multiple myeloma (MM) emerge, identification of biological markers which could predict clinical response to standard treatment with high-dose melphalan (HDM) supported by autologous stem cell transplantation (ASCT) becomes more important.. Melphalan-induced damage formation and repair of monoadducts and interstrand cross-links in the p53 gene were studied in peripheral blood mononuclear cells obtained from 32 patients prior to therapy. The same studies were performed in the peripheral blood cells of these patients immediately after subsequent HDM administration. Clinical response and time to progression were correlated with molecular endpoints obtained in vitro.. Values for all molecular end-points examined in vitro were highly correlated with the respective in vivo results within individual patients. All in vitro end-points indicative of increased DNA damage and slower repair capacity were predictive of a favorable response to HDM; the area under the curve of total adducts (AUC-TA) had the highest predictive ability. Using the cut-off value of 736 adducts/10(6) nucleotides x h for the AUC-TA, the positive predictive value for clinical response to HDM was 100%. Moreover, patients with an AUC-TA equal to or higher than this cut-off value had significantly longer times to progression than had patients with an AUC-TA lower than the cut-off value (hazard ratio 0.19; 95% confidence intervals 0.06 to 0.60).. An in vitro assay to quantify melphalan-induced p53-specific damage formation/repair can be used to select those patients with MM who are more likely to benefit from HDM supported by ASCT.

Combination of rituximab and oral melphalan and prednisone in newly diagnosed multiple myeloma.
    Leukemia & lymphoma, 2007, Volume: 48, Issue:12

    Clonotypic B lymphocytes may underlie relapse of patients with multiple myeloma. Rituximab, a CD20 monoclonal antibody, may result in eradication of the monoclonal B cells. We conducted a phase II study of rituximab in combination with melphalan and prednisone therapy (MP) followed by rituximab maintenance in newly diagnosed multiple myeloma patients. Sixteen patients (35%) had CD20 positive bone marrow plasma cells, while 9 patients (20%) had unknown CD20 status. No patient had a complete remission, 26 patients (58%) had a partial response, 6 patients (13%) had a minimal response, and 8 patients (18%) had stable disease. The median event-free survival was 14 months, and the 7-year overall survival was 30%. The toxicity of the combination was overall manageable and consistent with what is generally noted with MP chemotherapy. The combination of rituximab to MP therapy did not result in improved response rate or event-free survival.

Bortezomib inhibits osteoclast activity in patients with multiple myeloma.
    Clinical lymphoma & myeloma, 2007, Volume: 7, Issue:9

    The antimyeloma agent bortezomib functions as an inhibitor of nuclear factor (NF)-kappaB. Although NF-kappaB inhibition is predicted to affect osteoclast function, preclinical and clinical studies have primarily reported an effect on osteoblasts.. We examined parameters of bone turnover prospectively in patients with multiple myeloma treated with bortezomib before and after autologous transplantation. Thirty-nine patients received 2 cycles of bortezomib on days 1, 4, 8, and 11 of a 21-day cycle. After high-dose melphalan with autologous stem cell transplantation, bortezomib 1.3 mg/m2 on days 1, 8, 15, and 22 of a 5-week cycle was administered as maintenance therapy.. During posttransplantation bortezomib, decreases in the urinary excretion of collagen N-telopeptide indicated that bortezomib suppresses osteoclast function.. The effects on osteoclasts occurred in the absence of bisphosphonate treatment and independently of changes in monoclonal protein levels. Further studies exploring the role of bortezomib as a bone protective agent could be warranted.

Tandem autologous stem cell transplantation in high-risk de novo multiple myeloma: final results of the prospective and randomized IFM 99-04 protocol.
    Blood, 2006, Jan-01, Volume: 107, Issue:1

    The combination of high levels of beta2-microglobulin (beta2-m) and chromosome 13 deletion allows identification of a high-risk subgroup of patients with de novo multiple myeloma (MM). In this population of patients, we have evaluated the impact of a murine anti-interleukin 6 (anti-IL-6) monoclonal antibody (BE-8) as part of the second conditioning regimen in a multicenter prospective randomized trial of tandem autologous stem cell transplantation (ASCT). Conditioning for the first ASCT was accomplished with melphalan 200 mg/m2 and for the second one with melphalan 220 mg/m2 plus dexamethasone with or without BE-8 infusion. This trial included 219 patients, of whom 166 were randomized, 85 without BE-8 (arm A) and 81 with BE-8 (arm B). The median overall survival (OS) and event-free survival (EFS) times of the whole group of patients were 41 and 30 months, respectively. Response rates, OS, and EFS were not different between the 2 arms of the trial. OS at 54 months was 46% in arm A and 51% in arm B (P = .90); median EFS was 35 months in arm A and 31 in arm B (P = .39). In high-risk patients the dose intensity of melphalan at 420 mg/m2 led to encouraging results, but the addition of anti-IL-6 monoclonal antibody to the second conditioning regimen did not improve either OS nor EFS.

Dexamethasone-based regimens versus melphalan-prednisone for elderly multiple myeloma patients ineligible for high-dose therapy.
    Blood, 2006, Feb-15, Volume: 107, Issue:4

    Dexamethasone alone increases life expectancy in patients with relapsed multiple myeloma (MM); however, no large randomized study has compared dexamethasone and dexamethasone-based regimens with standard melphalan-prednisone in newly diagnosed MM patients ineligible for high-dose therapy. In the Intergroupe Francophone du Myélome (IFM) 95-01 trial, 488 patients aged 65 to 75 years were randomized between 4 regimens of treatment: melphalan-prednisone, dexamethasone alone, melphalan-dexamethasone, and dexamethasone-interferon alpha. Response rates at 6 months (except for complete response) were significantly higher among patients receiving melphalan-dexamethasone, and progression-free survival was significantly better among patients receiving melphalan (P < .001, for both comparisons), but there was no difference in overall survival between the 4 treatment groups. Moreover, the morbidity associated with dexamethasone-based regimens was significantly higher than with melphalan-prednisone, especially for severe pyogenic infections in the melphalan-dexamethasone arm and hemorrhage, severe diabetes, and gastrointestinal and psychiatric complications in the dexamethasone arms. Overall, these results indicated that dexamethasone should not be routinely recommended as first-line treatment in elderly patients with MM. In the context of the IFM 95-01 trial, the standard melphalan-prednisone remained the best treatment choice when efficacy and patient comfort were both considered. These results might be useful in the context of future combinations with innovative drugs.

Sequential, cycling maintenance therapy for post transplant multiple myeloma.
    Bone marrow transplantation, 2006, Volume: 37, Issue:1

    High-dose chemotherapy with autologous stem cell transplantation in patients with newly diagnosed multiple myeloma can prolong survival but is not curative. Maintenance therapy post transplant may prolong the disease-free interval and impact overall survival. We have conducted a phase II pilot study of 28 post transplant myeloma patients treated with a sequential, cycling maintenance regimen. The regimen was designed to include a variety of active myeloma agents chosen for ease of administration to enhance patient compliance and scheduled sequentially to minimize toxicity. The 12-month cycling schedule included dexamethasone (months 1-3); melphalan and prednisone (months 4, 5); cyclophosphamide and prednisone (months 6, 7); alpha-interferon (months 8-10); followed by a drug holiday (months 11, 12). The regimen was generally well tolerated with five patients developing reversible grade III-IV toxicity (diabetes-induced hyperglycemia in four, neutropenia in one). There was one toxic death on study due to non-neutropenic pneumonia and sepsis. Median event-free survival from transplant was 36.9 months (95% CI 23.6 - upper limit not yet reached) with median overall survival not yet reached at a median follow-up of 44 months. This concept of cycling, sequential maintenance with various agents, perhaps including newer biological, targeted agents, warrants further investigation in multiple myeloma.

Results of a phase I/II trial adding carmustine (300 mg/m2) to melphalan (200 mg/m2) in multiple myeloma patients undergoing autologous stem cell transplantation.
    Leukemia, 2006, Volume: 20, Issue:2

    Autologous stem cell transplantation (SCT) with high-dose melphalan (HDM, 200 mg/m2) is the most effective therapy for multiple myeloma. To determine the feasibility of combining carmustine (300 mg/m2) with HDM, we enrolled 49 patients with previously treated Durie-Salmon stage II/III myeloma (32M/17W, median age 53) on a phase I/II trial involving escalating doses of melphalan (160, 180, 200 mg/m2). The median beta2-microglobulin was 2.5 (0-9.3); marrow karyotypes were normal in 88%. The phase I dose-limiting toxicity was > or =grade 2 pulmonary toxicity 2 months post-SCT. Other endpoints were response rate and progression-free survival (PFS). HDM was safely escalated to 200 mg/m2; treatment-related mortality was 2% and > or =grade 2 pulmonary toxicity 10%. The complete (CR) and near complete (nCR) response rate was 49%. With a median post-SCT follow-up of 2.9 years, the PFS and overall survival (OS) post-SCT were 2.3 and 4.7 years. PFS for those with CR or nCR was 3.1 years while for those with stable disease (SD) it was 1.3 years (P=0.06). We conclude that carmustine can be combined with HDM for myeloma with minimal pulmonary toxicity and a high response rate.

Treatment of bendamustine and prednisone in patients with newly diagnosed multiple myeloma results in superior complete response rate, prolonged time to treatment failure and improved quality of life compared to treatment with melphalan and prednisone--a
    Journal of cancer research and clinical oncology, 2006, Volume: 132, Issue:4

    This randomized phase III study compared bendamustine and prednisone (BP) to standard melphalan and prednisone (MP) treatment in previously untreated patients with multiple Myeloma (MM).. To be included, patients had to have histologically and cytologically proven stage II with progressive diseases or stage III MM. They were randomly assigned to receive BP (n=68) or MP (n=63). The primary endpoint was the time to treatment failure (TTF). Secondary endpoints included survival, remission rate, toxicity and quality of life.. The overall response rate was 75% in the BP and 70% in the MP group. A significantly higher number of patients treated with BP achieved a complete remission than did patients receiving MP (32 vs. 13%; P=0.007), and the maximum response was achieved more rapidly in patients treated with BP compared to those receiving MP (6.8 vs. 8.7 cycles; P<0.02). TTF and remission duration were significantly longer in the BP group. Patients receiving BP had higher QoL scores and reported pain less frequently than patients receiving MP.. BP is superior to MP with respect to complete remission rate, TTF, cycles needed to achieve maximum remission and quality of life and should be considered the new standard in first-line treatment of MM patients not eligible for transplantation.

Phase I/II trial assessing bortezomib and melphalan combination therapy for the treatment of patients with relapsed or refractory multiple myeloma.
    Journal of clinical oncology : official journal of the American Society of Clinical Oncology, 2006, Feb-20, Volume: 24, Issue:6

    Bortezomib has shown synergy with melphalan in preclinical models. We assessed the safety, tolerability, and response rate in a dose-escalation study of this combination for relapsed or refractory multiple myeloma patients.. Bortezomib was administered from 0.7 to 1.0 mg/m(2) on days 1, 4, 8, and 11 of a 28-day cycle for up to eight cycles. Oral melphalan was administered in escalating doses from 0.025 to 0.25 mg/kg on days 1 to 4.. Thirty-five patients with relapsed or refractory myeloma were enrolled, 34 of whom were assessable for response. Dose-limiting toxicity of grade 4 neutropenia in two of six patients in the highest dose cohort led to the assignment of bortezomib 1.0 mg/m2 and melphalan 0.10 mg/kg as the maximum-tolerated dose (MTD). Responses (minimal [MR], partial [PR], or complete [CR]) occurred in 23 of 34 patients (68%), including two CRs (6%), three immunofixation-positive CRs (9%), 11 PRs (32%), and seven MRs (21%). Responses were observed in five of six assessable patients (83%) at the MTD. Median progression-free survival for all patients was 8 months (range, 2 to 18 months). Grade > or = 3 toxicities were related mostly to myelosuppression. Among the 15 patients with grade 1/2 neuropathy at baseline, it resolved during treatment in one, worsened in four, and remained stable in 10 patients. Eight other patients developed grade 1/2 neuropathy during the study.. Bortezomib plus melphalan given on a 28-day schedule showed encouraging activity with manageable toxicity and represents a promising treatment for myeloma patients.

Standard chemotherapy compared with high-dose chemoradiotherapy for multiple myeloma: final results of phase III US Intergroup Trial S9321.
    Journal of clinical oncology : official journal of the American Society of Clinical Oncology, 2006, Feb-20, Volume: 24, Issue:6

    Results of a prospective randomized trial conducted by the Intergroupe Francais du Myélome (IFM 90) indicated that autologous hematopoietic cell-supported high-dose therapy (HDT) effected higher complete response rates and extended progression-free survival (PFS) and overall survival (OS) compared with standard-dose therapies (SDT) for patients with multiple myeloma (MM).. In 1993, three North American cooperative groups launched a prospective randomized trial (S9321) comparing HDT (melphalan [MEL] 140 mg/m2 plus total-body irradiation 12 Gy) with SDT using the vincristine, carmustine, MEL, cyclophosphamide, and prednisone regimen. Responders on both arms (> or = 75%) were randomly assigned to interferon (IFN) or no maintenance treatment.. With a median follow-up time of 76 months, no differences were observed in response rates between the two study arms (HDT, n = 261 patients; SDT, n = 255 patients). Similarly, PFS and OS durations did not differ between the HDT and SDT arms, with 7-year estimates of PFS of 17% and 16%, respectively, and OS of 37% and 42%, respectively. Of 242 patients achieving at least 75% tumor reduction, no difference was observed in PFS or OS among the 121 patients randomly assigned to IFN and the 121 patients randomly assigned to no maintenance therapy. Among 157 patients relapsing on SDT, 87 received a salvage autotransplantation; their median survival time of 30 months was only slightly better than the survival time of the remaining patients who were managed with further SDT (23 months; P = .13).. The HDT and SDT regimens used in S9321 yielded comparable response rates and PFS and OS durations. IFN maintenance therapy did not benefit patients who achieved > or = 75% tumor reduction on either arm.

Primary treatment with pulsed melphalan, dexamethasone and thalidomide for elderly symptomatic patients with multiple myeloma.
    Haematologica, 2006, Volume: 91, Issue:2

    Fifty patients with multiple myeloma >or=75 years of age received primary treatment with melphalan (M) 8 mg/m(2) on days 1-4, dexamethasone (D) 12 mg/m2 on days 1-4 and 17-20 and thalidomide (T) 300 mg at bedtime on days 1-4 and 17-20. This regimen was repeated every 5 weeks for three courses. Patients without evidence of disease progression received nine additional courses of MDT, but without DT on days 17-20, every 5 weeks. Sixty-two percent of patients achieved a partial response and 10% a complete response. The median time to response was 2 months. The median time to progression for all patients was 21.2 months. Deep venous thrombosis and peripheral neuropathy each occurred in 9% of patients.

Intravenous melphalan, thalidomide and prednisone in refractory and relapsed multiple myeloma.
    European journal of haematology, 2006, Volume: 76, Issue:4

    Thalidomide combined with conventional chemotherapies including oral melphalan shows significant anti-myeloma activity. To address this issue, feasibility and efficacy of a three drug combination consisting of intravenous (i.v.) melphalan, thalidomide and prednisone [M(i.v.)PT] was evaluated in advanced myeloma patients.. Twenty-four advanced myeloma patients were treated with multiple cycles of a regimen consisting of low dose i.v. melphalan (20 mg/m2) at d 1, thalidomide at the dose of 50-100 mg/d given continuously and oral prednisone at the planned dose of 50 mg/d every other day. Intravenous melphalan was administered every fourth month. Median time from diagnosis was 40 months (range: 8-144 months). Fifteen patients (66%) had previously been treated with a combination of thalidomide and dexamethasone or with thalidomide alone.. Overall, on an intent-to treat basis, 14 patients responded: three achieved near complete remission (nCR), seven achieved partial response (PR), four minimal response (MR). Six patients showed stable disease (SD) and four-disease progression. Interestingly, of five patients who had previously progressed while on thalidomide and prednisone, one reached nCR, two PR and one MR. After a median follow up of 14 months, median progression free survival was 9 months. Response duration was longer than that induced by the previous line of treatment in eight patients (33%). Thalidomide-associated toxicity mainly consisted of constipation, tingling and sedation.. M(i.v.)PT is an effective regimen, which can overcome resistance to thalidomide plus prednisone in advanced myeloma with acceptable toxicity.

Thalidomide and hematopoietic-cell transplantation for multiple myeloma.
    The New England journal of medicine, 2006, Mar-09, Volume: 354, Issue:10

    High-dose therapy with melphalan can prolong survival among patients with multiple myeloma. We assessed whether the addition of thalidomide, which has activity against advanced and refractory myeloma, would further improve survival.. Between October 1998 and February 2004, 668 patients with newly diagnosed multiple myeloma received two cycles of intensive melphalan-based chemotherapy, each supported by autologous hematopoietic stem-cell transplantation. A total of 323 were randomly assigned to receive thalidomide from the outset until disease progression or undue adverse effects, and 345 did not receive thalidomide. The primary end point was the five-year event-free survival rate. Secondary end points were complete response and overall survival.. After a median follow-up of 42 months among survivors, the thalidomide and control groups had rates of complete response of 62 percent and 43 percent, respectively (P<0.001), and five-year event-free survival rates of 56 percent and 44 percent (P=0.01). The five-year rate of overall survival was approximately 65 percent in both groups (P=0.90). Median survival after relapse was 1.1 years in the thalidomide group and 2.7 years in the control group (P=0.001). Severe peripheral neuropathy and deep-vein thrombosis occurred more frequently in the thalidomide group than in the control group.. When incorporated into high-dose therapy for myeloma, thalidomide increased the frequency of complete responses and extended event-free survival at the expense of added adverse effects without improving overall survival.

Oral melphalan and prednisone chemotherapy plus thalidomide compared with melphalan and prednisone alone in elderly patients with multiple myeloma: randomised controlled trial.
    Lancet (London, England), 2006, Mar-11, Volume: 367, Issue:9513

    Since 1960, oral melphalan and prednisone (MP) has been regarded as the standard of care in elderly multiple myeloma patients. This multicentre randomised trial compared oral MP plus thalidomide (MPT) with MP alone in patients aged 60-85 years.. Patients with newly diagnosed multiple myeloma were randomly assigned to receive oral MP for six 4-week cycles plus thalidomide (n=129; 100 mg per day continuously until any sign of relapse or progressive disease) or MP alone (n=126). Analysis was intention-to-treat. This study is registered at , number NCT00232934.. Patients treated with thalidomide had higher response rates and longer event-free survival (primary endpoints) than patients who were not. Combined complete or partial response rates were 76.0% for MPT and 47.6% for MP alone (absolute difference 28.3%, 95% CI 16.5-39.1), and the near-complete or complete response rates were 27.9% and 7.2%, respectively. 2-year event-free survival rates were 54% for MPT and 27% for MP (hazard ratio [HR] for MPT 0.51, 95% CI 0.35-0.75, p=0.0006). 3-year survival rates were 80% for MPT and 64% for MP (HR for MPT 0.68, 95% CI 0.38-1.22, p=0.19). Rates of grade 3 or 4 adverse events were 48% in MPT patients and 25% in MP patients (p=0.0002). Introduction of enoxaparin prophylaxis reduced rate of thromboembolism from 20% to 3% (p=0.005).. Oral MPT is an effective first-line treatment for elderly patients with multiple myeloma. Anticoagulant prophylaxis reduces frequency of thrombosis. Longer follow-up is needed to assess effect on overall survival.

Complete response in multiple myeloma: clinical trial E9486, an Eastern Cooperative Oncology Group study not involving stem cell transplantation.
    Cancer, 2006, May-01, Volume: 106, Issue:9

    The importance of obtaining a complete response (CR) in multiple myeloma (MM) treated with chemotherapy is unclear.. The Eastern Cooperative Oncology Group evaluated 653 previously untreated patients with active MM randomized to vincristine, carmustine (BCNU), melphalan, cyclophosphamide, and prednisone (VBMCP), to VBMCP and recombinant interferon alfa-2 (INFalpha-2), or to VBMCP and high-dose cyclophosphamide.. Objective response was achieved in 420 (67%) of the 628 eligible patients, and 85 (14%) achieved a CR. Patients receiving VBMCP and recombinant INFalpha-2 had a significantly higher CR (18%) than those receiving VBMCP alone (10%) (P = .02). The CR rate for VBMCP and high-dose cyclophosphamide was 12%. Median duration of survival was 3.5 years for all eligible patients, and the estimated 5-year survival rate was 31%. The median duration of survival from the date of objective response was 5.1 years for those who achieved a CR and 3.3 years for those with a partial response (P < .0001). The median postresponse survival was 6.6 years in the 21 patients in CR with nonclonal disease and 4.4 years in the 11 patients in CR who had persistent clonal disease. All patients with negative immunofixation results and nonclonal plasma cells in whom polymerase chain reaction was performed had a positive result (presence of tumor DNA).. Patients in whom a CR was achieved had a longer survival than those who had a partial response.

Circulating levels and clinical significance of soluble CD86 in myeloma patients.
    British journal of haematology, 2006, Volume: 133, Issue:2

    Circulating soluble CD86 (sCD86) levels are elevated in a number of leukaemias and are an independent prognostic factor in acute myeloid leukaemia. We investigated the clinical significance of circulating sCD86 in 299 patients from the UK Medical Research Council myeloma VIth trial, where patients received ABCM [adriamycin, carmustine (BCNU), cyclophosphamide, melphalan] either alone or with prednisolone (ABCM + P). Serum levels of sCD86 were significantly elevated (P = 0.0001) in myeloma patients and using the median normal donor level (0.621 ng/ml) as a cut-off point, 70% of patients had elevated levels (range = 0.015-15.87 ng/ml, median = 1.1 ng/ml). In univariate analysis elevated sCD86 levels were associated with significantly shorter (P < 0.001) survival (median = 22 vs. 51 months) and event-free survival (median = 14 vs. 31 months) in ABCM + P but not ABCM patients. Multivariate analysis demonstrated that sCD86 was a significant, independent prognostic marker of both overall [risk ratio (RR) = 2.04, P = 0.0006] and event-free (RR = 1.95, P = 0.0004) survival in ABCM + P patients. In conclusion, this study demonstrated that sCD86 levels are a significant independent prognostic marker in at least some myeloma treatment groups and its biological role and prognostic value should be further investigated.

Effect of chemotherapy with alkylating agents on the yield of CD34+ cells in patients with multiple myeloma. Results of the Spanish Myeloma Group (GEM) Study.
    Haematologica, 2006, Volume: 91, Issue:5

    Although alkylating agents are clearly beneficial in multiple myeloma (MM), their deleterious effect on bone marrow hematopoietic progenitor cells usually precludes their use as front-line therapy in patients scheduled to undergo autologous stem cell transplantation (ASCT). We analyzed the impact of first-line chemotherapy with alkylating agents on stem cell collection in MM patients.. Seven hundred and eighty-nine patients included in the Spanish multicenter protocol GEM-2000 underwent mobilization therapy after four courses of alternating VBMCP/VBAD chemotherapy.. The mobilization regimens consisted of standard or high-dose granulocyte colony-stimulating factor (G-CSF) in 551 (70%) patients, and chemotherapy and G-CSF in 206 (26%) patients. The CD34+ cell yield was lower than 4x10(6)/kg in 388 patients (49%), and equal or greater than 4x10(6)/kg in 401 patients (51%). Multivariate analysis indicated that advanced age (p<0.0001) and longer interval between diagnosis and mobilization (p=0.012) were the two variables associated with a lower CD34+ cell yield. Significant differences in CD34+ cell yield were not observed between the mobilization regimens. Of the 789 patients included in the protocol, 726 (92%) underwent the planned ASCT, whereas 25 (3%) patients did not because of the low number of CD34+ cells collected. Following ASCT, 0.5x10(9) neutrophils/L could be recovered after 11 days (median time; range, 5-71 days) and 20x10(9) platelets/L could be recovered after 12 days (median time; range, 6-69 days).. A short-course of therapy with alkylating agents according to the GEM-2000 protocol was associated with an appropriate CD34+ cell collection, and allowed the planned ASCT to be performed in the majority of MM patients.

A prospective, randomized study of cryotherapy during administration of high-dose melphalan to decrease the severity and duration of oral mucositis in patients with multiple myeloma undergoing autologous peripheral blood stem cell transplantation.
    Bone marrow transplantation, 2006, Volume: 37, Issue:11

    Forty patients with multiple myeloma scheduled to receive melphalan 200 mg/m(2) followed by autologous stem cell transplantation were randomly assigned to receive oral cryotherapy or room temperature normal saline rinses 30 min before and for 6 h after high-dose therapy. Patients were evaluated for the development of mucositis using the National Cancer Institute grading system as well as evaluation of secondary measures such as days of total parenteral nutrition (TPN), narcotic use, hospitalization, weight loss and resumption of oral caloric intake for 28 days after transplant. Patients self-scored their pain, swallowing, drinking, eating, sleeping and taste alterations for 28 days. The primary end point of this trial was the incidence of grades 3-4 mucositis. Compared to the normal saline group, patients using cryotherapy experienced less grade 3-4 mucositis, 14 vs 74%, P=0.0005. Patients receiving cryotherapy also had statistically lower uses of narcotics and TPN, although there were no differences in length of hospitalization or weight loss. Patient-reported pain was significantly lower and activities were significantly better in the cryotherapy group.

Impact of age on survival after intensive therapy for multiple myeloma: a population-based study by the Nordic Myeloma Study Group.
    British journal of haematology, 2006, Volume: 133, Issue:4

    The value of intensive therapy, including autologous stem cell transplantation, in newly diagnosed myeloma patients >60 years is not clear. We evaluated the impact of age (<60 years vs. 60-64 years) on survival in a prospective, population-based setting and compared survival with conventionally treated historic controls. The prospective population comprised 452 patients registered between 1998 and 2000. Of these, 414 received intensive therapy. The historic population, derived from our most recent population-based study on conventional therapy, comprised 281 patients. Of these, 243 fulfilled our eligibility criteria for intensive therapy. For patients undergoing intensive therapy it was found that two factors, beta-2-microglobulin and age <60 years vs. 60-64 years, had independent prognostic impact on survival. However, compared with the historic controls a survival advantage was found both for patients <60 (median 66 months vs. 43 months, P < 0.001) and 60-64 years (median 50 months vs. 27 months; P = 0.001). We conclude that in a population-based setting higher age adversely influences outcome after intensive therapy. Our results indicate that intensive therapy prolongs survival also at age 60-64 years but with less superiority than in younger patients.

High-dose melphalan (200 mg/m2) supported by autologous stem cell transplantation is safe and effective in elderly (>or=65 years) myeloma patients: comparison with younger patients treated on the same protocol.
    Bone marrow transplantation, 2006, Volume: 37, Issue:10

    Limited information is available on the feasibility and efficacy of autologous stem cell transplantation (ASCT) in multiple myeloma (MM) patients >65 years of age. In 1995-2005, 22 myeloma patients >or=65 years (median 68, eight >or=70) and 79 patients <65 years (median 57) were included in an identical treatment protocol. The first progenitor cell mobilization with cyclophosphamide plus granulocyte-colony stimulating factor (G-CSF) was successful in 95 and 96% of the patients, respectively. To date, 92 patients have received MEL (melphalan) 200 mg/m2 supported by ASCT. No early treatment-related deaths were observed among 22 elderly patients, whereas one younger patient died early. Engraftment and the need for supportive care were comparable between groups. The elderly patients tended to have more WHO grade 3-4 oral or gastrointestinal toxicity when compared to the younger patients (45 vs 23%, P=0.06). After ASCT, a complete response was observed in 44% of the elderly patients and 36% of the younger patients, respectively. No difference was observed between these age groups in progression-free survival (23 vs 21 months) or overall survival (57 vs 66 months) after ASCT. We conclude that MEL200 is a safe and efficacious treatment in selected elderly myeloma patients.

Prolonged overall survival with second on-demand autologous transplant in multiple myeloma.
    American journal of hematology, 2006, Volume: 81, Issue:6

    Between August 1993 and March 2003, 130 consecutive multiple myeloma (MM) patients eligible for high-dose treatment were offered a program including up-front autologous stem cell transplantation (ASCT) after conditioning with 200 mg/m(2) melphalan followed by a second ASCT in case of relapse or progression. A total of 107 (82%) patients completed the first ASCT. The best response obtained after ASCT was complete response (CR) 23%, very good partial response (VGPR) 28%, partial response (PR) 42%, and minimal response (MR) 7%. Median overall survival (OS) and event-free survival (EFS) were 65.4 and 27.7 months, respectively. Relapse or progression occurred in 70 patients; 26 received a second ASCT (with a median time of 20.4 months from first ASCT). A major response (> or =PR) was obtained in 69% of these patients. Median OS and EFS after the second ASCT were 38.1 and 14.8 months. Treatment-related mortality was 1.9% after the first ASCT but no deaths occurred after the second. Our experience suggests that elective up-front single ASCT followed by second ASCT after relapse or progression is a safe and effective global strategy to treat MM patients.

Bortezomib plus melphalan and prednisone in elderly untreated patients with multiple myeloma: results of a multicenter phase 1/2 study.
    Blood, 2006, Oct-01, Volume: 108, Issue:7

    Standard first-line treatment for elderly multiple myeloma (MM) patients ineligible for stem cell transplantation is melphalan plus prednisone (MP). However, complete responses (CRs) are rare. Bortezomib is active in patients with relapsed MM, including elderly patients. This phase 1/2 trial in 60 untreated MM patients aged at least 65 years (half older than 75 years) was designed to determine dosing, safety, and efficacy of bortezomib plus MP (VMP). VMP response rate was 89%, including 32% immunofixation-negative CRs, of whom half of the IF- CR patients analyzed achieved immunophenotypic remission (no detectable plasma cells at 10(-4) to 10(-5) sensitivity). VMP appeared to overcome the poor prognosis conferred by retinoblastoma gene deletion and IgH translocations. Results compare favorably with our historical control data for MP--notably, response rate (89% versus 42%), event-free survival at 16 months (83% versus 51%), and survival at 16 months (90% versus 62%). Side effects were predictable and manageable; principal toxicities were hematologic, gastrointestinal, and peripheral neuropathy and were more evident during early cycles and in patients aged 75 years or more. In conclusion, in elderly patients ineligible for transplantation, the combination of bortezomib plus MP appears significantly superior to MP, producing very high CR rates, including immunophenotypic CRs, even in patients with poor prognostic features.

Intermediate-dose melphalan (100 mg/m2)/bortezomib/thalidomide/dexamethasone and stem cell support in patients with refractory or relapsed myeloma.
    Clinical lymphoma & myeloma, 2006, Volume: 6, Issue:6

    Bortezomib and thalidomide have shown synergy with melphalan and dexamethasone. We used this 4-drug combination as conditioning before autologous hematopoietic cell infusions.. Twenty-six patients with advanced-stage myeloma were treated with melphalan 50 mg/m(2) and bortezomib 1.3 mg/m(2) on days -6 and -3 in association with thalidomide 200 mg and dexamethasone 20 mg on days -6 through -3, followed by hematopoietic cell support on day 0.. Nonhematologic toxicities included pneumonia, febrile neutropenia, and peripheral neuropathy. All patients had undergone autologous transplantation at diagnosis, and 13 patients (50%) underwent an additional transplantation at relapse. Responses occurred in 17 of 26 patients (65%), including 1 complete remission, 3 near complete remissions (12%), and 2 very good partial remissions (8%). Response rate was higher than that induced by the previous line of treatment in 12 patients (46%).. Melphalan/bortezomib/thalidomide/dexamethasone showed encouraging antimyeloma activity in patients with advanced-stage myeloma.

High-dose therapy and autologous peripheral blood stem cells transplantation followed by a very low reduced intensity regimen with fludarabine + cyclophosphamide and allograft improve complete remission rate in de novo multiple myeloma patients.
    American journal of hematology, 2006, Volume: 81, Issue:12

    The recent development of reduced intensity conditioning and allotransplantation (RICT) has opened a new way to assure engraftment of donor cells while reducing early transplant-related mortality. We evaluated the combination of high-dose therapy and autologous peripheral blood stem cells transplantation (APBSCT) followed by RICT to extend the benefit of allografting procedures in de novo multiple myeloma (MM) patients. Fifteen subjects with stage III MM (median age 51 years, range 40-57) received high dose melphalan (200 mg/m(2)) followed by APBSCT previously collected after cyclophosphamide (4 g/m(2)) and granulocyte colony-stimulating factor (G-CSF). After 3-4 months from APBSCT, the patients underwent RICT, consisting of fludarabine 30 mg/m(2) + cyclophosphamide 300 mg/m(2) on days -4, -3, and -2. Acute graft-versus-host disease (GVHD) occurred in 2 patients; 6 patients developed chronic GVHD; 4 patients developed CMV antigenemia and were treated pre-emptively with ganciclovir. No transplant related mortality was shown. Response was simultaneously measured by both electrophoresis (EP) and immunofixation (IF); when IF was negative, patients were classified in complete remission (CR) and when it remained positive, near CR (nCR). After a median follow up of 44 months post APBSCT, 100 and 43% of patients are still alive and progression-free, respectively. Overall, the CR + nCR rate after dose-reduced allograft was enhanced from 26.7 to 73.3%. A correlation not statistically significant between GVHD and remission was found. In conclusion, an up-front tandem strategy with a very low reduced intensity-conditioning regimen for allografting following autografting is feasible and induces high CR/nCR rate in MM.

Pegfilgrastim compared with filgrastim after high-dose melphalan and autologous hematopoietic peripheral blood stem cell transplantation in multiple myeloma patients.
    European journal of haematology, 2006, Volume: 77, Issue:5

    We undertook a comparative study of Pegfilgrastim vs. Filgrastim after high-dose melphalan and autologous peripheral blood stem cell transplantation (APBSCT) in multiple myeloma (MM) patients. Thirty-seven consecutive patients were randomly assigned to receive a single 6 mg dose of Pegfilgrastim on day 1 post-transplant (n = 18 patients) vs. daily subcutaneous injections of Filgrastim 5 microg/kg (n = 19 patients) starting on day 5 post-transplant. The median duration of grade 4 neutropenia in the Pegfilgrastim and Filgrastim groups was 5 and 6 d, respectively (P = ns). The results for the two groups were also not significantly different for time to neutrophil and platelet recovery, but incidence of febrile neutropenia (61.1% vs. 100%, P = 0.003) and duration of febrile neutropenia (1.5 d vs. 4 d, P = 0.005), were lower in the Pegfilgrastim arm. After initial haematopoietic reconstitution, we observed significantly higher value of leukocytes x 10(9) L on day 15 (6.0 vs. 2.7, P = 0.004), in the Pegfilgrastim group compared with the Filgrastim group. This study shows that a single injection Pegfilgrastim can be used with safety and efficacy similar to those provided by daily injections of Filgrastim and it is associated with a decrease incidence of infectious events after APBSCT in MM patients.

    A single injection of pegfilgrastim has been shown to be equivalent to daily filgrastim in enhancing neutrophil recovery after chemotherapy, whereas the experiences with pegfilgrastim in mobilization of peripheral blood progenitor cells (PBPCs) are limited.. Forty unselected patients with lymphoma or multiple myeloma were treated with different chemotherapy regimens followed by 6 mg of pegfilgrastim for mobilization of autologous PBPCs.

Long-term outcome results of the first tandem autotransplant trial for multiple myeloma.
    British journal of haematology, 2006, Volume: 135, Issue:2

    Total Therapy 1, the first tandem autotransplant trial for newly diagnosed patients with multiple myeloma, was designed to increase the frequency of complete response (CR) and thereby extend survival. With a median follow-up of 12 years, 62 of 231 initially enrolled patients are alive (17% at 15 years); 31 remain event free (7% at 15 years) including 16 of 94 (41%) that initially achieved CR. Currently alive patients less frequently had cytogenetic abnormalities (CAs) at baseline (P = 0.002), postenrolment (P < 0.001) and at relapse (P = 0.004); elevations of serum C-reactive protein (CRP) (P = 0.003) and lactate dehydrogenase (P = 0.029), anaemia (P = 0.029) and they more often completed two transplants within 12 months (P = 0.019). Postenrolment overall survival (OS) and event-free survival (EFS) were superior in the absence of CA of the hypodiploidy or deletion 13 variety (P < 0.001 and 0.037 respectively) and in the presence of low CRP at baseline (P = 0.001 and 0.017 respectively). Postrelapse survival was longer in the absence of CA at relapse (P < 0.001), IgA isotype (P = 0.002), International Staging System stage 3 (P = 0.014), and when patients had two protocol transplants prior to relapse (P = 0.038). Ten-year EFS and OS could be accomplished in 15% and 33% of patients, respectively, when all agents available in 1989, especially high-dose melphalan, were applied together upfront for the management of myeloma.

Pegylated liposomal doxorubicin, melphalan and prednisone therapy for elderly patients with multiple myeloma.
    Hematological oncology, 2006, Volume: 24, Issue:4

    Melphalan & Prednisone (MP) is considered as the standard therapy for Multiple Myeloma (MM) patients not eligible for high-dose therapy. Here, we report the results of a phase I-II study to evaluate the feasibility and efficacy of the association of PLD to the conventional MP regimen during the first six cycles of the front-line therapy for untreated MM patients older than 70. Thirty patients were included in the study with a median age of 77 years (71-84) and a M/F ratio of 17/13. The phase I of the study demonstrated that the maximum tolerable dose of PLD in this setting was 30 mg/m(2), so it was the final dose evaluated in the study. Twenty-nine patients were valuable for response, which was: complete in 4 (14%) partial in 15 (52%) minor/no changes in 7 (24%) and progressive in 3 (10%). The median progression free survival (PFS) was 24 months. The median overall survival (OS) has not been reached yet, with a 3-year probability for OS and PFS of 52 and 37%, respectively. Haematological toxicity was frequent but usually weak/moderate (grades 1 & 2 of the WHO scale) and it was resolved only with dose delays. Infection was a relatively frequent event (30% of patients), but only in 4 cases it was of grade 3. No cases of palmar-plantar erythrodysesthesia were observed. In conclusion, pegylated liposomal doxorubicin can be safely added to the other chemotherapeutic drugs in the treatment of elderly MM patients, which can be very useful for patients in whom novel agents are not tolerated or inefficient.

Efficacy and safety of melphalan, arsenic trioxide and ascorbic acid combination therapy in patients with relapsed or refractory multiple myeloma: a prospective, multicentre, phase II, single-arm study.
    British journal of haematology, 2006, Volume: 135, Issue:2

    We assessed the safety and efficacy of melphalan, arsenic trioxide (ATO) and ascorbic acid (AA) (MAC) combination therapy for patients with multiple myeloma (MM) who failed more than two different prior regimens. Patients received melphalan (0.1 mg/kg p.o.), ATO (0.25 mg/kg i.v.) and AA (1 g i.v) on days 1-4 of week 1, ATO and AA twice weekly during weeks 2-5 and no treatment during week 6 of cycle 1; during cycles 2-6, the schedule remained the same except ATO and AA were given twice weekly in week 1. Objective responses occurred in 31 of 65 (48%) patients, including two complete, 15 partial and 14 minor responses. Median progression-free survival and overall survival were 7 and 19 months respectively. Twenty-two patients had elevated serum creatinine levels (SCr) at baseline, and 18 of 22 (82%) showed decreased SCr levels during treatment. Specific grade 3/4 haematological (3%) or cardiac adverse events occurred infrequently. Frequent grade 3/4 non-haematological adverse events included fever/chills (15%), pain (8%) and fatigue (6%). This steroid-free regimen was effective and well tolerated in this heavily pretreated group. These results indicate that the MAC regimen is a new therapeutic option for patients with relapsed or refractory MM.

A phase I study of 153Sm-EDTMP with fixed high-dose melphalan as a peripheral blood stem cell conditioning regimen in patients with multiple myeloma.
    Leukemia, 2005, Volume: 19, Issue:1

    Despite response rates of 30% after high-dose chemotherapy with autologous hematopoietic stem cell transplant, patients with multiple myeloma are not cured. 153Samarium ethylenediaminetetramethylenephosphonate (153Sm-EDTMP; Quadramet) is a short-range, beta-emitting therapeutic radiopharmaceutical with avid skeletal uptake. In total, 12 patients were treated with escalating doses of 153Sm-EDTMP (N=3/group; 6, 12, 19.8, and 30 mCi/kg) and a fixed dose of melphalan (200 mg/m(2)). No dose limiting toxicity was seen. To better standardize the marrow compartment radiation dose, the study was modified such that an additional six patients were treated at a targeted absorbed radiation dose to the red marrow of 40 Gy based on a trace labeled infusion 1 week prior to the therapy. Despite rapid elimination of unbound radiopharmaceutical via kidneys and bladder, no episodes of nephrotoxicity, hemorrhagic cystitis, or delayed radiation nephritis were observed with a median follow-up of 31 months (range 8.5-44). Median times to ANC>0.5 and platelet >20 x 10(6)/l were 12 and 11 days, respectively, with no graft failures. Overall response rate was 94% including seven very good partial responses and five complete responses. Addition of 153Sm EDTMP to melphalan conditioning appears to be safe, well-tolerated and worthy of further study.

Successful transplantation of peripheral blood stem cells mobilized by chemotherapy and a single dose of pegylated G-CSF in patients with multiple myeloma.
    Bone marrow transplantation, 2005, Volume: 35, Issue:1

    Following induction therapy and 4 g/m(2) cyclophosphamide, a single dose of 12 mg polyethyleneglycol-conjugated G-CSF (pegfilgrastim; n=12) or daily doses of unconjugated G-CSF (8.5 mug/kg/day) (n=12) were administered to myeloma patients. Pegfilgrastim was associated with an earlier leukocyte recovery (12 vs 14 days) and peripheral blood CD34+ cell peak (12 vs 15 days). The peripheral blood CD34+ cell peak was lower in the pegfilgrastim group (78 vs 111/mul). Following high-dose melphalan (200 mg/m(2)) and autografting, leukocyte and platelet reconstitution was similar in both groups and stable blood counts were observed 100 days post transplant. In summary, a single dose of pegfilgrastim after chemotherapy is capable of mobilizing a sufficient number of CD34+ cells for successful autografting with early engraftment and sustained hematological reconstitution in patients with myeloma. These data provide the basis for randomized studies evaluating the optimal dose and time of pegfilgrastim as well as long-term outcome in larger cohorts of patients.

Hematopoietic stem cell mobilization with intravenous melphalan and G-CSF in patients with chemoresponsive multiple myeloma: report of a phase II trial.
    Bone marrow transplantation, 2005, Volume: 35, Issue:5

    Multiple myeloma (MM) is an incurable hematologic malignancy for which autologous hematopoietic stem cell transplantation (HCT) is a standard therapy. The optimal method of stem cell mobilization is not defined. We evaluated intravenous melphalan (60 mg/m2), the most effective agent for MM, and G-CSF (10 microg/kg/day) for mobilization. End points were safety, adequacy of CD34+ collections, MM response, and contamination of stem cell components (SCC). In total, 32 patients were mobilized. There were no deaths or significant bleeding episodes; 14 patients (44%) required hospitalization for neutropenic fever. Median days of grade 3 or 4 neutropenia or thrombocytopenia were 7 (2-20) and 8 (3-17). Median mobilization days, CD34+ cells/kg and total leukaphereses were 16 (12-30), 12.1 million (2.6-52.8), and 2 (1-5) respectively. Four patients (12.5 %) failed to achieve the target of 4 million CD34+ cells/kg in five leukaphereses. Reduction in myeloma was seen in 11 patients (34%) with 3 (9%) achieving complete response; 15 (47%) maintained prior responses. Estimated MM contamination per SCC (N=48) was 0.0009% (range 0-0.1) and 0.21 x 10(4) cells per kg (range 0-41.2). Increased contamination was associated with increased patient age. This strategy for mobilization is feasible, frequently requires hospitalization and transfusion, and controls disease in most patients.

Biological modifiers as cytoreductive therapy before stem cell transplant in previously untreated patients with multiple myeloma.
    Annals of oncology : official journal of the European Society for Medical Oncology, 2005, Volume: 16, Issue:2

    High dose chemotherapy with supporting autologous stem cell transplantation is now considered the treatment of choice in patients with multiple myeloma <65 years old. The best regimen appears to be VAD (vincristine, doxorubicin and dexamethasone), but acute and late toxicity can limit the use of this combination. The use of biological modifiers has not been considered in this situation. We developed a new cytoreductive regimen, in an attempt to retain clinical efficacy but reduce toxicity.. Thirty-six patients, previously untreated with diagnosis of multiple myeloma were enrolled to received the DAI regimen (dexamethasone 30 mg/m(2), i.v., days 1-4, all-trans-retinoic acid 45 mg/m(2), p.o., days 5-14 and interferon alpha 2a, 4.5 MU s.c., days 5-14) administered every 28 days for six cycles before high-dose chemotherapy (melphalan 200 g/m(2)) and autologous stem cell transplantation.. Overall response was observed in 29 cases (80%), complete response in 19 and partial response in 10 patients. Five patients were >65 years old and were treated with dexamethasone/thalidomide. Twenty-four patients underwent transplants. At a median follow-up of 31.6 months, no relapse or disease progression was observed, thus actuarial curves at 3-years showed that event-free survival was 86% and overall survival was 94%. Toxicity was mild.. This regimen appears to be an excellent alternative as cytoreductive treatment before high-dose chemotherapy and autologous stem cell transplantation with excellent overall response and minimal toxicity. Controlled clinical trials are warranted to define the role of this new therapeutic approach.

Toxicity in standard melphalan-prednisone therapy among myeloma patients with renal failure--a retrospective analysis and recommendations for dose adjustment.
    British journal of haematology, 2005, Volume: 128, Issue:5

    Haematological and infectious toxicity was correlated to renal function in 272 newly diagnosed myeloma patients given standard dose melphalan-prednisone (MP) as initial treatment without dose adjustment for renal impairment. The glomerular filtration rate (GFR) was estimated by calculated creatinine clearance. Haematological toxicity was found to be significantly related to renal dysfunction. Haematological toxicity World Health Organization (WHO) grades 3-4 after the first MP course was seen in 18%, 28% and 36% of patients with a creatinine clearance of >50, 30-50 and <30 ml/min respectively. WHO grades 3-4 infections occurred in 6% and were not significantly related to renal function. We conclude that MP therapy can be used for initial therapy in myeloma patients with renal impairment but suggest that reduction of the melphalan dose should be considered in patients with a GFR of <30 ml/min. As only 2% of our patients had a clearance of < or =10 ml/min no conclusions can be drawn for this subgroup.

Prospective randomised trial of amifostine cytoprotection in myeloma patients undergoing high-dose melphalan conditioned autologous stem cell transplantation.
    Bone marrow transplantation, 2005, Volume: 35, Issue:10

    In this prospective multicentre trial, 90 patients undergoing autologous stem cell transplantation (ASCT) were randomised to receive (n=43) or not receive (n=47) amifostine 910 mg/m(2) prior to melphalan 200 mg/m(2). Patients were monitored for regimen-related toxicity, engraftment, supportive care, response and survival. Both groups underwent ASCT at a median of 8 months from diagnosis and were matched for disease characteristics, prior therapy and pre-ASCT disease responsiveness. Amifostine infusional side-effects were frequent, occurring in 65% of patients, but of mild severity. Amifostine use was associated with a reduction in the median grade of oral mucositis (1 vs 2, P=0.01) and the frequency of severe (WHO grades 3 or 4) mucositis (12 vs 33%, P=0.02), but no reduction in the requirement for parenteral nutrition or analgesic use. Conversion to complete remission post-ASCT occurred in 30 and 14% of the amifostine and control groups, respectively (P=0.09). With a median follow-up of 35 months, there was no statistically significant difference between the median progression-free or overall survival times for the two groups. We conclude that amifostine can be safely administered prior to high-dose melphalan and significantly reduces the frequency and severity of therapy-induced oral mucositis.

The maturation of myeloma cells correlates with sensitivity to chemotherapeutic agents.
    International journal of hematology, 2005, Volume: 81, Issue:4

    We analyzed both morphologic and phenotypic findings of myeloma cells before and after chemotherapy in 21 patients with multiple myeloma. The morphologic analysis was based on the Greipp classification, and phenotypic analysis was performed by 3-color flow cytometry using the CD38 plasma gating method (Marrow plasma 38). Results with flow cytometry using a combination of MPC1, CD49e, and CD45 supported the morphologic findings for the myeloma cells. Treatment with 3 or 4 cycles of VAD (vincristine, doxorubicin, and dexamethasone) therapy was effective in reducing the total numbers of myeloma cells, but the proportion of immature myeloma cells increased after this treatment. However, the immature myeloma cells were reduced by high-dose melphalan (HD-Mel) therapy followed by autologous stem cell transplantation (ASCT). High-dose cyclophosphamide treatment for stem cell harvesting did not show an effect on the residual immature myeloma cells after VAD treatment. In addition, thalidomide was not effective in reducing the numbers of immature myeloma cells. These results suggest that VAD (3 or 4 cycles) therapy plus HD-Mel followed by ASCT is a reasonable treatment for multiple myeloma and that Marrow plasma 38 analysis is a useful method for monitoring the response of multiple myeloma to chemotherapy.

High-dose idarubicin, cyclophosphamide and melphalan as conditioning for autologous stem cell transplantation increases treatment-related mortality in patients with multiple myeloma: results of a randomised study.
    British journal of haematology, 2005, Volume: 130, Issue:4

    We conducted a randomised trial comparing an intensified versus a standard conditioning regimen for high-dose chemotherapy followed by autologous stem-cell transplantation in patients with multiple myeloma. In this study, 56 patients were randomly assigned for high-dose therapy with melphalan 200 mg/m2 or with idarubicin 42 mg/m2, melphalan 200 mg/m2 and cyclophosphamide 120 mg/kg. The primary objective was response rate. Acute toxicity, mainly because of infections, was higher in the intensified treatment arm with a treatment-related mortality of 20% versus 0% in the standard arm. This lead to the early discontinuation of the study. Response rates did not differ significantly between both treatment arms {intensified versus standard: complete response+near complete remission 50% [95% confidence interval (CI) 26-74%] vs. 33% (95% CI 17-55%), partial remission 35% (95% CI 16-61%) vs. 50% (95% CI 30-70%)}. After a follow-up of 5 years, the median time-to-progression and overall survival were not significantly different between both patient groups. Analysis restricted to patients surviving the first 100 d after transplant showed a better outcome for patients with >or=2 bad prognostic risk factors in the intensified treatment arm, however all treatment-related deaths occurred within this group of patients. In conclusion, intensified conditioning for high-dose therapy had intolerably high toxicity without improving outcome in patients with multiple myeloma.

High-dose therapy intensification compared with continued standard chemotherapy in multiple myeloma patients responding to the initial chemotherapy: long-term results from a prospective randomized trial from the Spanish cooperative group PETHEMA.
    Blood, 2005, Dec-01, Volume: 106, Issue:12

    The aim of the present randomized trial was to compare high-dose therapy (HDT) with continued conventional chemotherapy in patients with multiple myeloma (MM) who responded to the initial treatment. From May 1994 to October 1999, 216 patients (122 men/94 women; stage II or III; Eastern Cooperative Oncology Group [ECOG] score less than 3) entered the study. Initial chemotherapy consisted of 4 cycles of alternating vincristine, BCNU, melphalan, cyclophosphamide, prednisone/vincristine, BCNU, Adriamycin, dexamethasone (VBMCP/VBAD). Responding patients were randomly assigned to receive 8 additional cycles of VBMCP/VBAD, intensification with melphalan 200 mg/m2, or melphalan 140 mg/m2 plus 12 Gy fractionated total body irradiation (TBI). One-hundred sixty-four patients were randomly assigned, 83 to continued chemotherapy and 81 to HDT. The complete remission (CR) rate was significantly higher with HDT (30% vs 11%; P = .002). However, progression-free survival (PFS) was not significantly different between HDT and conventional therapy (median, 42 vs 33 months; P = not significant [NS]), and overall survival (OS) was similar in both groups (median, 61 vs 66 months). Finally, survival after relapse was identical in the 2 arms (15.9 vs 16.4 months). In conclusion, these results show that HDT intensification, when given to myeloma patients who have responded to the initial chemotherapy, significantly increases the CR rate but has no significant impact on PFS or OS.

Optimizing the use of anti-interleukin-6 monoclonal antibody with dexamethasone and 140 mg/m2 of melphalan in multiple myeloma: results of a pilot study including biological aspects.
    Bone marrow transplantation, 2005, Volume: 36, Issue:9

    Interleukin-6 (IL-6) is a major survival factor for multiple myeloma (MM) cells preventing apoptosis induced by dexamethasone (DEX) or chemotherapy. In all, 24 consecutive patients with MM in first-line therapy received DEX for 4 days, followed by melphalan (HDM: 140 mg/m2) and autologous stem cell transplantation (ASCT). The anti-IL-6 monoclonal antibody (mAb) (B-E8) was given till haematological recovery, starting 1 day before DEX. Results were historically compared to MM patients treated with HDM 140 and 200 mg/m2. Our results show (1) that B-E8 was able to fully neutralize IL-6 activity in vivo before and after HDM as shown by inhibition of C reactive protein (CRP) production; (2) no haematological toxicity; (3) a significant reduction of mucositis and fever; (4) a median event-free survival of 35 months and an overall survival of 68.2% at 5 years with a median follow-up of 72 months; and (5) the overall daily IL-6 production progressively increased on and after 7 days post-HDM, with the increased serum CRP levels. In the 5/24 patients with uncontrolled CRP production, a large IL-6 production was detected (320 microg/day) that could not possibly be neutralized by B-E8. These data show the feasibility to neutralize IL-6 in vivo with anti-IL-6 mAb in the context of HDM.

Continuous prednisolone versus conventional prednisolone with VMCP-interferon-alpha2b as first-line chemotherapy in elderly patients with multiple myeloma.
    British journal of haematology, 2005, Volume: 131, Issue:3

    We report on a randomised trial that aimed to compare the efficacy of continued daily prednisolone treatment during the entire induction phase, with prednisolone given for 2 weeks of each cycle in combination with VMCP (vincristine, melphalan, cyclophosphamide, prednisolone)-interferon-alpha 2b (IFN-alpha 2b) treatment in 299 previously untreated elderly patients (median age: 67 years) with multiple myeloma. After completion of induction treatment patients were randomised to IFN-alpha 2b with or without prednisolone, thrice weekly. Response rate was 62% in the continuous and 60% in the control arm (intent to treat analysis, P=0.81). Progression-free survival [median: 20 months vs. 19 months; hazard ratio (HR): 0.99, 95% confidence interval (CI): 0.74-1.33, P=0.97] and overall survival (median: 34 months vs. 37 months; HR: 1.16, 95% CI: 0.85-1.59, P=0.35) were similar in both groups. Reduced performance status (Eastern Cooperative Oncology Group, grades 2-4) was the predominant risk factor for poor survival followed by age >65 years, high beta2-microglobulin, and impaired renal function. There was more grades 3-4 dyspnoea and cardiac impairment and grades 1-2 hyperglycaemia, but less nausea, emesis and anaemia in patients on continuous prednisolone therapy. In conclusion, continuing prednisolone treatment during the entire duration of the induction phase with VMCP-IFN-alpha 2b did not improve outcome.

High-dose therapy and autologous blood stem-cell transplantation compared with conventional treatment in myeloma patients aged 55 to 65 years: long-term results of a randomized control trial from the Group Myelome-Autogreffe.
    Journal of clinical oncology : official journal of the American Society of Clinical Oncology, 2005, Dec-20, Volume: 23, Issue:36

    To study the impact of high-dose therapy (HDT) with autologous stem-cell support in patients with symptomatic multiple myeloma (MM) between the ages of 55 and 65 years.. One hundred ninety patients between 55 and 65 years old who had newly diagnosed stage II or III MM were randomly assigned to receive either conventional chemotherapy (CCT; ie, monthly courses of a regimen of vincristine, melphalan, cyclophosphamide, and prednisone) or HDT and autologous blood stem-cell transplantation (using either melphalan alone 200 mg/m(2) intravenous [IV] or melphalan 140 mg/m(2) IV plus busulfan 16 mg/kg orally as pretransplantation cytoreduction).. Within a median follow-up of 120 months, median event-free survival (EFS) times were 25 and 19 months in the HDT and CCT groups, respectively. Median overall survival (OS) time was 47.8 months in the HDT group compared with 47.6 months in the CCT group. A trend to better EFS (P = .07) was observed in favor of HDT, whereas OS curves were not statistically different (P = .91). The period of time without symptoms, treatment, and treatment toxicity (TwiSTT) was significantly longer for the HDT patients than for the CCT patients (P = .03).. With a median follow-up time of approximately 10 years, this randomized trial confirmed a benefit of HDT in terms of EFS and TwiSTT but did not provide evidence for superiority of HDT over CCT in OS of patients aged 55 to 65 years with symptomatic newly diagnosed MM.

Multiple myeloma: comparison of two dose-intensive melphalan regimens (100 vs 200 mg/m(2)).
    Leukemia, 2004, Volume: 18, Issue:1

    Several trials have shown the superior impact of high-dose melphalan (usually 200 mg/m(2), MEL200) vs standard therapy in myeloma patients. Intermediate-dose melphalan (100 mg/m(2), MEL100) is also superior to the standard dose, but has not been clinically compared with MEL200. A total of 90 patients at diagnosis were treated with two MEL100 courses. Their clinical outcome was compared with that of a control group of 90 pair mates matched for serum beta2-microglobulin levels and Durie and Salmon clinical stage. These patients were treated at diagnosis with two MEL200 courses. Patient characteristics were similar in both groups except that the median age of the MEL100 group was significantly higher (P<0.0001). Complete remission was 35% after MEL100 and 48% after MEL200 (P=0.08). Median event-free survival (EFS) was 32 months in the MEL100 group and 42 months in the MEL200 group (P<0.005), but overall survival (OS) was not different. Transplant-related mortality was not significantly different. Haematological and extra-haematological toxicity was significantly reduced after MEL100. Despite the significant age difference, tandem MEL100 was less toxic than tandem MEL200, and MEL100 was inferior to MEL200 in terms of EFS but not in terms of OS. The intensified nonmyeloablative MEL100 regimen is an effective first-line treatment.

High-dose therapy/autologous stem cell transplantation in patients with chemosensitive multiple myeloma: predictors of complete remission.
    Bone marrow transplantation, 2004, Volume: 33, Issue:1

    High-dose therapy (HDT) followed by autologous stem cell support is widely used as intensification treatment in patients with multiple myeloma (MM) responsive to the initial chemotherapy. However, there is growing evidence that only the subset of patients who achieve complete remission (CR) actually benefit from this approach. The aim of this study was to identify pretransplant predictors of CR in responding myeloma patients intensified with HDT. A total of 59 patients with chemosensitive disease received myeloablative therapy. The intensification regimen consisted of MEL-200 (23), MEL-140/TBI 12 Gy (21) or busulfan-based regimens (15). Serum and urine negative immunofixation were required for CR. After HDT, the CR rate increased from 8 to 37%. For the overall series, the median event-free survival (EFS) and overall survival (OS) from the initiation of therapy were 41 and 68 months, respectively. Patients who achieved CR had an EFS (median 47 vs 36 months; P=0.023) as well as an OS (median not reached vs 60 months; P=0.006) significantly longer than those attaining a lower degree of response. Finally, the pretransplant features significantly associated to CR were a low M-protein size (serum

Phase III study of ranimustine, cyclophosphamide, vincristine, melphalan, and prednisolone (MCNU-COP/MP) versus modified COP/MP in multiple myeloma: a Japan clinical oncology group study, JCOG 9301.
    International journal of hematology, 2004, Volume: 79, Issue:2

    To investigate whether combination chemotherapy with vincristine, cyclophosphamide, prednisolone, and melphalan (COP/ MP) with the addition of ranimustine (MCNU) (MCNU-COP/MP) is superior to the slightly modified COP/MP (mCOP/MP) regimen in multiple myeloma (MM), a multicenter randomized study was performed. Two hundred ten patients with newly diagnosed, overt MM not treated with chemotherapy were enrolled from 32 institutions of the Lymphoma Study Group of the Japan Clinical Oncology Group and were randomized to receive either MCNU-COP/MP or mCOP/MP. The response rate (RR) to mCOP/MP was 43.7% (95% confidence interval [CI], 33.9%-53.8%] and to MCNU-COP/MP was 56.1% (95% CI, 46.1%-65.7%) (P = .097). The progression-free survival (PFS) was significantly longer for patients treated with MCNU-COP/MP than for patients treated with mCOP/MP (median, 23.0 months [95% CI, 18.9-25.8] versus 15.8 months [95% CI, 14.1-19.4]) (P = .014). However, no significant difference in overall survival rate (OS) was observed between the groups (median, 49.9 months [95% CI, 40.4-59.1] versus 44.0 months [95%, CI, 32.8-59.8]) (P = .75). Grades 3 and 4 hematological toxicities were more frequently observed with MCNU-COP/MP than with mCOP/MP, but the incidence of grades 3 and 4 nonhematological toxicities was low in both groups. In conclusion, MCNU-COP/MP in comparison with mCOP/MP improved RR and PFS in overt MM; however, this outcome did not contribute to prolonging OS, indicating that addition of MCNU to mCOP/MP has no benefit on survival.

Early response to therapy and survival in multiple myeloma.
    British journal of haematology, 2004, Volume: 125, Issue:2

    Whether the response to chemotherapy is a prognosticator in multiple myeloma (MM) is still not known. Therefore, the relationship between survival and the rate of monoclonal protein (M-protein) decrement during the first cycles of therapy was prospectively assessed in 262 patients with newly diagnosed MM that were included in a phase III trial (HOVON-16). M-proteins were collected monthly during melphalan-prednisone therapy (MP: melphalan 0.25 mg/kg, prednisone 1.0 mg/kg orally for 5 d every 4 weeks). Patients with light chain disease (n = 18), immunoglobulin M (IgM)-MM (n = 1) and no immunotyping (n = 1) were excluded. Of the 242 patients studied, 75% had IgG M-protein and 25% IgA; MM stages: I: 1%, II: 35% and III: 64%. The median M-protein decrease after the first cycle of MP was 21% for IgG and 27% for IgA, and declined to < 5% after four cycles. An obvious survival advantage was seen for patients who had an M-protein decrease of at least 30% after the first MP cycle, which became significant when an M-protein decrease of 40% or more was reached. As established prognostic parameters (Salmon & Durie stage, serum creatinine, and haemoglobin) also remained prognostically significant, we concluded that early response to MP predicts for survival in MM.

A cost-utility analysis comparing intensive chemotherapy alone to intensive chemotherapy followed by myeloablative chemotherapy with autologous stem-cell rescue in newly diagnosed patients with stage II/III multiple myeloma; a prospective randomised phase
    European journal of cancer (Oxford, England : 1990), 2004, Volume: 40, Issue:8

    A prospective randomised phase III study in patients < or =65 years old with previously untreated multiple myeloma (MM), intensive chemotherapy followed by myeloablative chemotherapy and autologous stem-cell rescue was compared with intensive chemotherapy alone. This economic evaluation was based on detailed data from patient charts and hospital information systems. In the intention-to-treat analysis, mean total treatment and follow-up costs of the myeloablative treatment arm were 81,643 euros compared to 68,802 euros for the chemotherapy arm (P=0.09). Costs per quality-adjusted life year were 51,357 euros versus 37,328 euros. In the clinical study, no significant differences were found in overall survival after a median follow-up of 33 months from randomisation. Intensive chemotherapy is regarded as standard therapy for younger patients with previously untreated MM. Cost-effectiveness of myeloma therapy after 3 years of follow up seems not to be favoured by myeloablative treatment with autologous stem-cell rescue.

Common and rare side-effects of low-dose thalidomide in multiple myeloma: focus on the dose-minimizing peripheral neuropathy.
    European journal of haematology, 2004, Volume: 72, Issue:6

    Thalidomide has demonstrated a remarkable efficacy in the treatment of multiple myeloma but its use may cause several toxicities. We have investigated the common and rare side-effects, especially analysing peripheral neuropathy, in order to optimise the thalidomide dose for minimizing this harmful side-effect.. Fifty-nine patients were treated with thalidomide alone or combined with oral melphalan. The median age was 69 yr. The initial dose of thalidomide was 100 mg/day increasing weekly by 100 mg increments until a maximum dose of 400 mg was attained. Melphalan was administered at a dose of 0.20 mg/kg/d for 4 d every 28 d.. Nearly one-fourth of patients discontinued thalidomide because of toxicity. Constipation (71%), somnolence (36%) and fatigue (20%) were the most common side-effects and they were not dose dependent. Peripheral neuropathy occurred in 39% of patients and a thalidomide median daily dose of more than 150 mg was significantly associated with higher frequency and actuarial risk of peripheral neuropathy without improving the response rate. Deep venous thrombosis was observed in 7% of patients and other side-effects were rare. In patients with advanced multiple myeloma we found that a thalidomide daily dose of 150 mg minimizes peripheral neuropathy without jeopardizing response and survival.

High-dose topotecan, melphalan and cyclophosphamide (TMC) with stem cell support: a new regimen for the treatment of multiple myeloma.
    Leukemia & lymphoma, 2004, Volume: 45, Issue:4

    The goal of this trial was to assess the toxicity and potential efficacy of high-dose topotecan, melphalan and cyclophosphamide as a preparative regimen for patients with multiple myeloma undergoing autologous stem cell transplantation. Eighteen patients were treated, 8 for first remission consolidation, 4 with relapse sensitive disease, 3 primary refractory and 3 relapsed refractory. The median age was 56 (38 - 65) and the median number of prior regimens was 3 (1 - 8). Patients received cyclophosphamide 1 g/m2/d on days -6, -5, -4; melphalan 70 mg/m2 on days -3, -2 and topotecan 3.0 to 3.5 mg/m2/d on days -6 to -2. Peripheral blood stem cells were infused on day 0. Toxicity (Bearman Toxicity Criteria) was mostly limited to grade 1 - 2 mucositis and grade 1 diarrhea. There were no transplant-related deaths. The overall response rate at 3 months post transplantation was 89% with 17% CR, 2 of those in refractory patients. The overall response rate in refractory patients was 67%. With a median follow up of 12.3 months, 89% of patients are alive. The TMC regimen is well tolerated and produces high response rates. Further evaluation of TMC to fully assess response and survival is ongoing.

Intermediate-dose melphalan improves survival of myeloma patients aged 50 to 70: results of a randomized controlled trial.
    Blood, 2004, Nov-15, Volume: 104, Issue:10

    High-dose therapy is an effective standard treatment for multiple myeloma patients. Evidence that intermediate-dose therapy improves survival is limited. At diagnosis, about 70% of patients are older than 65. Intermediate-dose regimen is very well tolerated in older patients. In a multicenter study, 194 patients were randomized to receive at diagnosis either conventional chemotherapy (6 courses of oral melphalan and prednisone [MP]) or intermediate-dose therapy (2 courses of melphalan at 100 mg/m(2) [MEL100]) with stem cell support. Response rate was higher after MEL100. Near-complete remission (nCR) was 6% after MP and 25% after MEL100 (P = .0002). At 3 years, MEL100 increased event-free survival (EFS) from 16% to 37% and overall survival (OS) from 62% to 77% (P < .001). Similar results were observed in patients aged 65 to 70: nCR was 8% after MP and 25% after MEL100 (P = .05); at 3 years, MEL100 improved EFS from 18% to 31% (P = .01) and OS from 58% to 73% (P = .01). Patients aged 65 to 70 had a median OS of 37.2 months (MP) versus 58 months (MEL100). Intermediate-dose melphalan improves response rate, EFS, and OS in myeloma patients, specifically in those aged 65 to 70. It constitutes a more effective first-line regimen than standard treatment for elderly patients.

Thalidomide plus oral melphalan compared with thalidomide alone for advanced multiple myeloma.
    The hematology journal : the official journal of the European Haematology Association, 2004, Volume: 5, Issue:4

    Thalidomide, the prototype of a new class of agents active against multiple myeloma (MM), exerts synergistic/additive effects when combined with other drugs. The aim of this study was to compare the toxicity and efficacy of thalidomide alone and in combination with oral melphalan. Patients with advanced MM received 100 mg/day oral thalidomide escalated weekly up to 600 mg/day (n=23; T group), alone or with 0.20 oral mg/kg/die melphalan administered monthly for four consecutive days (n=27; TM group). A>/=50% paraprotein reduction was observed in 59% of TM compared with 26% of T patients (P=0.009); three TM patients were found to have an absence of paraprotein by immunofixation. After a median follow-up of 13 months (range 6-32), progression-free survival (PFS) at 2 years was significantly longer in the TM group (61 versus 45%; P=0.0376), whereas overall survival did not differ significantly. Toxicity was not significantly greater with the combination therapy; although DVT was more frequent (11 versus 4%), as was grade 3 leukopenia (30 versus 13%; P=0.073), there were no cases of severe infection. Thalidomide administered with oral melphalan improved response rates and PFS in patients with advanced MM without significantly increasing severe toxicity.

The VAD-DCEP sequence is an effective pre-transplant therapy in untreated multiple myeloma.
    Haematologica, 2004, Volume: 89, Issue:9

    Standard treatment for patients with multiple myeloma is debulking chemotherapy with non-alkylating agents followed by a regimen to mobilize peripheral blood stem cells (PBSC) and the transplantation of the mobilized, autologous PBSC. The aim of this study was to evaluate the efficacy of a new regimen and compare it with that of a previous regimen.. In a large cohort of 106 patients (group I) we administered a new pre-transplant program which includes 2 courses of pulsed-VAD (vincristine, adriamycin, dexamethasone) followed by 2 courses of DCEP (dexamethasone, cyclophosphamide, etoposide and cis-platinum). We compared the efficacy of this new VAD-DCEP sequence, in terms of mobilizing capacity, toxicity and anti-myeloma activity in comparison with that of the previous VAD-high-dose cyclophosphamide program (group II, 40 patients).. In group I 81/106 (76.4%) patients yielded >or= 4x10(6)/kg CD34+ cells, as did 30/40 (75%) in group II but with a significantly higher toxicity in this latter group. In detail, 9 patients in group I (8.5%) had WHO grade III neutropenia versus 35 in group II (87.5%), 5 patients of group I (4.7%) had grade III thrombocytopenia versus 12 patients in group II (30%), and 8 patients in group I (7.5%) experienced an infections fever versus 9 patients in group II (22.5%). Therefore, nearly all patients in group II had to be admitted to hospital (39/40, 97.5%). There was a higher percentage of responses (CR+VGPR+PR) in group I than in group II: 73% versus 50% (p=0.02).. the VAD-DCEP sequence has an adequate mobilizing capacity, without significant toxicity, and a good anti-myeloma activity, and therefore represents a safe and effective therapeutic approach for multiple myeloma patients at the onset of their disease.

Relapse to prior autograft and chronic graft-versus-host disease are the strongest prognostic factors for outcome of melphalan/fludarabine-based dose-reduced allogeneic stem cell transplantation in patients with multiple myeloma.
    Biology of blood and marrow transplantation : journal of the American Society for Blood and Marrow Transplantation, 2004, Volume: 10, Issue:10

    We evaluated prognostic factors of melphalan/fludarabine-based dose-reduced allografts in patients with multiple myeloma. From 1998 to 2002, 120 patients with multiple myeloma were treated with melphalan/fludarabine followed by allogeneic stem cell transplantation. The cumulative risk at 1 year for treatment-related mortality (TRM) was 18% (95% confidence interval [CI], 12%-28%). In a multivariate analysis, relapse after prior high-dose chemotherapy was the most significant risk factor for TRM (hazard ratio [HR], 2.80; 95% CI, 1.16-6.74; P =.02), relapse (HR, 4.14; 95% CI, 2.04-8.38; P <.001), event-free survival (HR, 3.11; 95% CI, 1.77-5.46; P <.001), and overall survival (HR, 2.69; 95% CI, 1.35-5.35; P =.005). In addition, relapse was also significantly diminished by chronic graft-versus-host disease (GVHD) in a time-dependent Cox model (HR, 0.37; 95% CI, 0.16-0.87; P =.02). At transplantation, 8% of the patients were in complete remission, whereas 27% had progressive disease. After allografting, 49% achieved complete remission, and 38% achieved partial remission. In a subgroup of patients with chemosensitivity at transplantation and no relapse after prior high-dose chemotherapy who underwent transplantation with peripheral blood stem cells (n = 46), the cumulative risk of TRM at 1 year was only 8% (95% CI, 1%-54%). The 2-year estimated event-free and overall survival was 60% (95% CI, 42%-78%) and 75% (95% CI, 59%-91%), respectively, for related donors (n = 34) and was 81% (95% CI, 59%-100%) and 92% (95% CI, 76%-100%), respectively, for unrelated donors (n = 12).

Randomized comparison of dexamethasone combined with melphalan versus melphalan with prednisone in the treatment of elderly patients with multiple myeloma.
    British journal of haematology, 2004, Volume: 127, Issue:2

    Melphalan-prednisone (MP) has been the gold standard treatment for more than 30 years in elderly multiple myeloma (MM) patients. In order to assess whether the combination of dexamethasone with melphalan (MD) could improve on the efficacy of MP, we have carried out a randomized trial comparing both treatment approaches. A total of 201 patients >/=70 years old were included in the study. The overall response rate was similar after six cycles (MP: 67.9%versus MD: 64.5%) and after 12 cycles (MP: 49.4%versus MD: 46.1%). However, the proportion of complete responses (CR) was higher in the MD arm, particularly after 12 cycles (MD: 22.4%versus MP: 9.1%; P < 0.05). There was no significant difference in event-free survival (MP: 15.9 months versus MD: 23.3 months). The median overall survival in both arms was almost identical (MP: 29.4 months versus MD: 27.2 months; P = 0.63). No significant differences in haematological toxicity were observed, but non-haematological toxicity was significantly higher in the MD arm. According to these results MP remains as the gold standard for treatment of MM and should be the reference for comparison of new therapeutic approaches involving novel agents.

Impaired PBPC collection in patients with myeloma after high-dose melphalan.
    Cytotherapy, 2004, Volume: 6, Issue:5

    Tandem stem cell transplantation is an important treatment option for patients with myeloma and some additional tumors. In an attempt to reduce the contamination of the stem cell graft with tumor cells, patients with myeloma who entered complete remission after the first transplant underwent a second episode of mobilization to obtain progenitor cells for the second transplant.. Twenty-two patients with myeloma participated in the study. The first mobilization utilized CY, etoposide and filgrastim. The second mobilization used the same regimen, but seven patients received only filgrastim. The interval between the two collection periods was 6 months (median; range 4-9 months). The preparative regimen for the first transplant consisted of melphalan 200 mg/m(2).. The number of total white cells collected during the two collection episodes was similar: 10.8+/-1.6 x 10(8)/kg white cells vs. 11.8+/-1.7 x 10(8)/kg white cells (P=0.63). The collected CD34(+) cell dose was much larger during the first collection: 45.2+/-8.4 x 10(6)/kg vs. 6.9+/-2.7 x 10(6)/kg (P<0.001). Similarly, the collected colony-forming unit (CFU)-GM dose was much larger during the first collection: 295.4+/-59.3 x 10(4)/kg vs. 67.3+/-21.6x10(4)/kg (P<0.001). While the CD34(+) cells collected during the two collection episodes correlated significantly (r=0.55, P<0.01); the first dose was a median of 14.9-fold larger.. No laboratory parameter was able reliably to predict the results of the second collection. A second mobilization/collection episode as part of a tandem transplant approach carries a considerable risk of failing to obtain sufficient progenitor cells.

A reduced intensity conditioning regimen for allografting following autografting is feasible and has strong anti-myeloma activity.
    Haematologica, 2004, Volume: 89, Issue:12

    Sixteen patients with stage III multiple myeloma (MM) and a median age of 51 years were treated with autografting followed by reduced intensity conditioning allotransplantation (RICT). Nine patients are alive in remission at a median of 30 months after their transplants, one patient is alive in relapse and 6 patients died of progressive disease (5) or extensive chronic graft-versus-host disease, infections and progressive disease (1). We suggest that this two-step approach is feasible and it has strong anti-myeloma activity.

Overall and event-free survival are not improved by the use of myeloablative therapy following intensified chemotherapy in previously untreated patients with multiple myeloma: a prospective randomized phase 3 study.
    Blood, 2003, Mar-15, Volume: 101, Issue:6

    We compared the efficacy of intensified chemotherapy followed by myeloablative therapy and autologous stem cell rescue with intensified chemotherapy alone in patients newly diagnosed with multiple myeloma. There were 261 eligible patients younger than 66 years with stage II/III multiple myeloma who were randomized after remission induction therapy with vincristine, adriamycin, dexamethasone (VAD) to receive intensified chemotherapy, that is, melphalan 140 mg/m(2) administered intravenously in 2 doses of 70 mg/m(2) (intermediate-dose melphalan [IDM]) without stem cell rescue (n = 129) or the same regimen followed by myeloablative therapy consisting of cyclophosphamide, total body irradiation, and autologous stem cell reinfusion (n = 132). Interferon-alpha-2a was given as maintenance. Of the eligible patients, 79% received both cycles of IDM and 79% of allocated patients actually received myeloablative treatment. The response rate (complete remission [CR] plus partial remission [PR]) was 88% in the intensified chemotherapy group versus 95% in the myeloablative treatment group. CR was significantly higher after myeloablative therapy (13% versus 29%; P =.002). With a median follow-up of 33 months (range, 8-65 months), the event-free survival (EFS) was not different between the treatments (median 21 months versus 22 months; P =.28). Time to progression (TTP) was significantly longer after myeloablative treatment (25 months versus 31 months; P =.04). The overall survival (OS) was not different (50 months versus 47 months; P =.41). Intensified chemotherapy followed by myeloablative therapy as first-line treatment for multiple myeloma resulted in a higher CR and a longer TTP when compared with intensified chemotherapy alone. However, it did not result in a better EFS and OS.

Response to first-line chemotherapy and long-term survival in patients with multiple myeloma: results of the MM87 prospective randomised protocol.
    European journal of cancer (Oxford, England : 1990), 2003, Volume: 39, Issue:1

    In this study we evaluated whether a good response to conventional chemotherapy, i.e. a significant tumour reduction, is a prerequisite for improved survival in multiple myeloma (MM). Between January 1987 and March 1990, 341 consecutive previously untreated patients with MM received chemotherapy within the prospective, multicentre, randomised Protocol MM87. Of these, 258 patients were evaluable for both response and long-term survival and 244 (94.6%) have died. The median survival of all patients was 40 months (6-162 months). The median survival did not differ between patients who had complete response (CR) (50 months (9-162 months)), partial response (PR) (46 months (8-147 months)) or stable disease (SD) (41 months (7-135 months)). The median survival was shorter (13.6 months (6-135 months)) (P<0.0001) in patients whose disease progressed while they were receiving first induction chemotherapy. Causes of death were more frequently (P=0.04) related to MM in patients who had progressive disease (PD) than in patients who had a CR or PR or SD. The main clinical and laboratory characteristics were similar in the four groups. These data indicate that patients who maintain SD during first-line chemotherapy have a prognosis similar to that of patients who attain a response. Only patients whose disease progresses have a distinctly worse outcome.

Melphalan-mobilized blood stem cell components contain minimal clonotypic myeloma cell contamination.
    Blood, 2003, Jul-15, Volume: 102, Issue:2

    Optimal methods of stem cell mobilization in multiple myeloma are undefined, and contaminating clonotypic cells could contribute to disease recurrence. A phase 2 trial of intravenous melphalan (60 mg/m2) and granulocyte colony-stimulating factor (G-CSF) (10 microg/kg/d) for mobilization was performed. To enhance reliability, contamination was assessed with 2 sensitive methods, immunoglobulin light and heavy chain variable region patient-specific limiting-dilution polymerase chain reaction (PCR). We evaluated 29 stem cell components (SCCs) from 15 patients; for 9 SCCs, only VL PCR was used because of light chain disease or technical problems with VH primers. For 20 SCCs, VL and VH PCR results were highly correlated (r2 = 0.93, P <.01), with 35% (7 of 20) having identical estimates. VH PCR gave significantly higher estimates for 8-and VL PCR for 5-SCCs, supporting the utility of using 2 methods. Estimated clonotypic contamination per SCC was 0.0009% (range, 0%-0.1%) or 0.5 x 10(4) clonotypic cells per kilogram (range, 0-41.2 x 10(4)/kg), and contamination correlated with CD34+ cells collected (r2 = 0.42, P <.01). Melphalan-mobilized SCCs contain minimal clonotypic contamination.

Cost-effectiveness of a transplantation strategy compared to melphalan and prednisone in younger patients with multiple myeloma.
    Leukemia & lymphoma, 2003, Volume: 44, Issue:1

    High dose chemotherapy with autologous stem cell transplantation (ASCT) improves outcomes in patients 65 years of age or less with multiple myeloma. Survival and costs in a cohort of 16 patients who received melphalan and prednisone as part of a clinical trial were compared with those of 36 patients referred to our centre for consideration of ASCT. In the transplant group, survival and costs were extrapolated to match the period of observation in the melphalan and prednisone group. Patient-specific and average costs were calculated from the perspective of the Ontario Ministry of Health. Costs and survival were varied by 50% in the sensitivity analysis. Transplantation improved life expectancy by 19.3 months with a cost difference of 30,517 Canadian dollars. The incremental cost-effectiveness of transplantation compared with melphalan and prednisone was 25,710 Canadian dollars per life-year gained when additional pamidronate and follow-up costs were considered. Discounting costs and survival at 3 and 5% did not result in important differences. The sensitivity analysis resulted in best and worse case scenarios for transplantation compared with melphalan and prednisone of 13,049 dollars and 63,954 dollars per life-year gained respectively. In comparison with melphalan and prednisone, ASCT appears to be cost-effective in patients 65 years old or younger with myeloma.

Comparative pharmacokinetic study of high-dose etoposide and etoposide phosphate in patients with lymphoid malignancy receiving autologous stem cell transplantation.
    Bone marrow transplantation, 2003, Volume: 31, Issue:8

    The pharmacokinetics of two etoposide (E) formulations were evaluated in patients with refractory hematologic malignancies receiving high-dose conditioning with autologous stem cell transplantation. Patients were randomized to either E at 800 mg/m(2) (containing polysorbate 80 and polyethylene glycol) or etoposide phosphate (EP) at 910 mg/m(2) on days -7 and -5, prior to melphalan, 80 mg/m(2) on day -5. On day -3, EP was repeated. Plasma E was analyzed after each formulation on days -7 and -5 to compare intrapatient pharmacokinetics. In total, 10 patients were treated: four each with multiple myeloma or Hodgkin's disease and two with non-Hodgkin's lymphoma. Mucositis was the major toxicity with seven patients. EP first produced grade 3 mucositis. There was no procedure-related mortality and eight patients remained alive 1 year post-transplant. Cumulative etoposide exposure (AUC) was slightly greater with EP (P=0.056). Conversely, the volume of distribution was slightly, 33%, larger (P=0.052) and clearance was increased with the E infusion (P=0.14). As none of the differences reached statistical significance, both E formulations appear to be pharmacokinetically equivalent in the high-dose transplant setting. The combination of high-dose EP with melphalan is an active preparative regimen prior to ABMT for hematologic malignancies.

Cyclin D1 overexpression is a favorable prognostic variable for newly diagnosed multiple myeloma patients treated with high-dose chemotherapy and single or double autologous transplantation.
    Blood, 2003, Sep-01, Volume: 102, Issue:5

    We used a sensitive real-time reverse transcription-polymerase chain reaction assay to quantify cyclin D1 mRNA levels in bone marrow samples collected at diagnosis from 74 newly diagnosed multiple myeloma (MM) patients who were randomized to undergo either single or double autologous peripheral blood stem cell transplantation as part of first-line therapy for their malignancy. In 46 cases, fluorescence in situ hybridization (FISH) analysis and/or conventional cytogenetics were performed to detect chromosome 11 abnormalities. Patients with the t(11;14) or trisomy 11 significantly overexpressed cyclin D1 (P <.0001) in comparison with patients without 11q abnormalities, who had cyclin D1 mRNA levels similar to healthy donors. Overall, 32 (43%) of 74 patients showed cyclin D1 overexpression. No difference was found between cyclin D1-positive (group A) and cyclin D1-negative (group B) patients with respect to presenting clinical and laboratory characteristics, including chromosome 13 abnormalities, as well as to response to therapy and overall survival, both of which were calculated on an intent-to-treat basis. Patients who overexpressed cyclin D1 had significantly longer duration of remission in comparison with patients who did not (41 vs 26 months, respectively; P =.02). As a result, median event-free survival (EFS) was longer in group A than in group B (33 vs 24 months, respectively; P =.055). We concluded that cyclin D1 overexpression is closely associated with 11q abnormalities and identifies a subset of MM patients who are more likely to have prolonged duration of remission and EFS following autologous transplantation.

High-dose chemotherapy with hematopoietic stem-cell rescue for multiple myeloma.
    The New England journal of medicine, 2003, May-08, Volume: 348, Issue:19

    High-dose therapy with supporting autologous stem-cell transplantation remains a controversial treatment for cancer. In multiple myeloma, first-line regimens incorporating high-dose therapy yield higher remission rates than do conventional-dose treatments, but evidence that this translates into improved survival is limited.. In this multicenter study, the Medical Research Council Myeloma VII Trial, we randomly assigned 407 patients with previously untreated multiple myeloma who were younger than 65 years of age to receive either standard conventional-dose combination chemotherapy or high-dose therapy and an autologous stem-cell transplant.. Among the 401 patients who could be evaluated, the rates of complete response were higher in the intensive-therapy group than in the standard-therapy group (44 percent vs. 8 percent, P<0.001). The rates of partial response were similar (42 percent and 40 percent, respectively; P=0.72), and the rates of minimal response were lower in the intensive-therapy group than in the standard-therapy group (3 percent vs. 18 percent, P<0.001). Intention-to-treat analysis showed a higher rate of overall survival (P=0.04 by the log-rank test) and progression-free survival (P<0.001) in the intensive-therapy group than in the standard-therapy group. As compared with standard therapy, intensive treatment increased median survival by almost 1 year (54.1 months [95 percent confidence interval, 44.9 to 65.2] vs. 42.3 months [95 percent confidence interval, 33.1 to 51.6]). There was a trend toward a greater survival benefit in the group of patients with a poor prognosis, as defined by a high beta2-microglobulin level (more than 8 mg per liter).. High-dose therapy with autologous stem-cell rescue is an effective first-line treatment for patients with multiple myeloma who are younger than 65 years of age.

Polymorphic variation in GSTP1 modulates outcome following therapy for multiple myeloma.
    Blood, 2003, Oct-01, Volume: 102, Issue:7

    Glutathione S-transferase P1 (GSTP1) is a phase 2 drug metabolism enzyme involved in the metabolism and detoxification of a range of chemotherapeutic agents. A single nucleotide polymorphism (Ile105Val) results in a variant enzyme with lower thermal stability and altered catalytic activity. We hypothesized that patients with the less stable variant have a decreased ability to detoxify chemotherapeutic substrates, including melphalan, and have an altered outcome following treatment for multiple myeloma. We have assessed the impact of GSTP1 codon 105 polymorphisms in 222 patients entered into the Medical Research Council (MRC) myeloma VII trial (comparing standard-dose chemotherapy with high-dose therapy). In the standard-dose arm, patients with the variant allele (105Val) had an improved progression-free survival (PFS) (adjusted hazard ratios for PFS were 0.55 for heterozygotes and 0.52 for 105Val homozygotes, compared with 105Ile homozygotes; P for trend =.04); this was supported by a trend to improved overall survival, greater likelihood of entering plateau and shorter time to reach plateau in patients with the 105Val allele. No difference in outcome by genotype was found for patients treated with high-dose therapy. However, the progression-free survival advantage of the high-dose arm was seen only in patients homozygous for 105Ile (P =.008).

Dosimetry of high dose skeletal targeted radiotherapy (STR) with 166Ho-DOTMP.
    Cancer biotherapy & radiopharmaceuticals, 2003, Volume: 18, Issue:2

    A study was undertaken to determine the maximum tolerated dose of (166)Ho-DOTMP that could be administered safely, without negatively impacting marrow re-engraftment, in patients with multiple myeloma treated with melphalan prior to transplant. Ho-166 DOTMP is a tetraphosphonate that localizes rapidly to bone surface. The Ho-166 physical half-life is 26.8 hr and the maximum beta energy is 1.8 MeV. Standard dosimetry models were adapted for radiation absorbed dose estimates using data obtained from whole body counting of the low abundance photons emitted by (166)Ho. Eighty-three patients received high dose (166)Ho-DOTMP followed by melphalan and transplant of peripheral blood stem cells. Twenty-five patients also received 8 Gy total body radiation (TBI). Dosages administered ranged from 460 to 4476 mCi (166)Ho-DOTMP. Marrow dose was derived using the assumption that all radioactivity not excreted by 20 hours was localized to the bone surfaces, and applying the Eckerman bone and marrow dose model to the calculated bone residence times. The dosimetry of the urinary bladder and kidneys was important because of the rapid excretion of the non-targeted radioactivity via the urinary pathway. The dynamic bladder model was used for bladder wall surface dose, and the ICRP 53 kinetic model was used to model kidney kinetics with an additional blood component included. Marrow doses ranged from 13 to 59 Gy and successful hematapoietic recovery occurred. Bladder doses ranged from 4.7 to 157 Gy. Hemorrhagic cystitis occurred in some patients who received more than 40 Gy to the bladder wall surface. Bladder irrigation was successful in protecting patients from bladder toxicity. Kidney doses ranged from 0.5-7.9 Gy. Kidney toxicity in the form of thrombotic microangiopathy with renal dysfunction was observed, with the severity being related to Ho-166-DOTMP radiation dose and probably the dose rate as well. In a future trial, kidney dosimetry will be assessed using early serial gamma camera imaging and modifications will be implemented to reduce renal toxicity.

Evaluation of relative anti-myeloma activity of high-dose melphalan followed by the first peripheral blood stem cell transplantation, as compared with the second transplantation, and to VAD chemotherapy.
    Transplantation proceedings, 2003, Volume: 35, Issue:6

    Current treatment in multiple myeloma consists of three courses of chemotherapy in low doses with subsequent hematopoietic stem cell mobilization to the peripheral blood using high-dose cyclophosphamide, collection and conditioning with high-dose chemotherapy (melphalan) followed by retransplantation of autologous peripheral blood stem cells (PBSCT). Only a few studies compare the effects of different phases of therapy on parameters, such as monoclonal immunoglobulin level and the presence of malignant CD38(+) and CD56(+) cells in blood and marrow. The aim of this study was to compare the effects of these two major phases of treatment (conventional and high dose) in the same patients, and furthermore, to compare the effects of the second course of high-dose therapy followed by PBSCT with the effects of the first one. Fifteen patients were included in the study. On average, conventional chemotherapy only slightly reduced the values of all disease markers. In contrast, high-dose therapy resulted in a dramatic effect, rapidly normalizing the values of all parameters. The effects of second PBSCT were only modest compared to the first. These data suggest that high-dose therapy is an efficient method to reduce tumor load in multiple myeloma. Conventional-dose chemotherapy may be simply a waste of time for some patients and may be either omitted or administered after high-dose therapy to consolidate remission.

Triple transplantation of autologous peripheral blood stem cells each time following conditioning with 100 mg/m2 of melphalan for multiple myeloma patients in poor performance status.
    Transplantation proceedings, 2003, Volume: 35, Issue:6

    Approximately one third of multiple myeloma patients (below 60 years) are diagnosed either in advanced disease or with significant comorbidities. Many other patients referred to transplant centers have already been heavily pretreated with multiple courses of various conventional chemotherapies. These patients are frequently in bad or even grave clinical condition; they are unlikely to survive standard high-dose melphalan (200 mg/m(3)) chemotherapy and autologous hematopoietic stem cell transplantation. Palumbo et al reported a protocol for elderly patients that utilized reduced conditioning (melphalan 100 mg/m(2) three times at 2-month intervals, each time supported by autologous hematopoietic rescue). We have used this protocol as a start to develop a method to induce a remission in the aforementioned subgroup of myeloma patients. Patients with stage III disease and WHO performance status 2 or higher are treated with one or two cycles of cyclophosphamide (2 to 4 g/m(2)) and undergo peripheral blood stem cells collection. Subsequently, they are treated with three to four doses of melphalan (100 mg/m(2)) at 8- to 12-weeks intervals each time supported by infusion of peripheral blood stem cells. To date 13 patients have been entered into the protocol. With one exception of transiently stable disease, the remaining patients obtained at least partial remission and three, complete remission. The compliance was good and better with each subsequent course. For half of the patients the problem was a short duration of response. This method when developed may offer a new treatment alternative for a subgroup of high-risk multiple myeloma patients.

High dose therapy followed by autologous peripheral blood stem cell transplantation as a first line treatment for multiple myeloma: a Korean Multicenter Study.
    Journal of Korean medical science, 2003, Volume: 18, Issue:5

    We conducted a phase II multicenter trial to estimate the response and survival of patients with newly diagnosed multiple myeloma to high dose melphalan therapy followed by autologous peripheral blood stem cell transplantation. Eligible patients who had undergone induction with vincristine, adriamycin and dexamethasone (VAD) should have adequate cardiac, pulmonary and renal function (creatinine <2 mg/dL). Melphalan at 200 mg/m2 was used as a conditioning regimen. Eighty patients were enrolled from 13 centers. The median age of the patients was 53 yr (range; 20 to 68 yr). The initial stage was IA/IIA/IIB/IIIA/IIIB in 3/8/1/54/14 patients, respectively. Beta2-microglobulin, CRP and LDH were increased in 74, 42 and 34% of the patients examined. Cytogenetic data were available in 30 patients, and 6 patients showed numeric or structural abnormalities. Two therapy-related mortalities occurred from infection. Among the 78 evaluable patients, CR/PR/MR/NC/PD were achieved in 48/26/2/1/1 patients, respectively. After a median follow-up of 30 months, the median overall and event-free survivals were 66 months (95% CI: 20-112) and 24 months (95% CI: 18-29), respectively. This study verifies the efficacy and feasibility of high dose melphalan therapy with autologous stem cell transplantation in newly diagnosed multiple myeloma.

The efficacy of high-dose melphalan with autologous peripheral blood stem cell transplantation in patients with multiple myeloma.
    Yonsei medical journal, 2003, Oct-30, Volume: 44, Issue:5

    Although high-dose therapy (HDT) with autologous hematopoietic stem cell transplantation (ASCT) is widely accepted as an effective and safe consolidation therapy for multiple myeloma (MM), few reports on its efficacy are available in Korea. We present the results of a prospective phase II study, involving 33 patients with MM treated with HDT with ASCT. The treatment consisted of 4 courses of VAD (vincristine, adriamycin, dexamethasone) induction, peripheral blood stem cell collection, and high-dose melphalan with stem cell infusion. The overall response rate was 93%, with 45% of patients having complete responses. The toxicity was predictable and tolerable. With a median follow-up of 27.6 months, the 2-year event free survival rate was 43%. At the time of writing, the median overall survival duration had not been reached with 2-year survival and projected 3-year survival rates of 81% and 74%, respectively. The overall survival was significantly better than that of the historical control patients (N=82) treated with conventional chemotherapy at our institution. The results suggest that HDT with ASCT is a valuable first or second-line treatment for patients with MM.

Autologous stem cell transplantation followed by a dose-reduced allograft induces high complete remission rate in multiple myeloma.
    Blood, 2002, Aug-01, Volume: 100, Issue:3

    We evaluated toxicity, engraftment, chimerism, graft-versus-host disease (GVHD), and response to a dose-reduced allograft after cytoreductive autografting in 17 patients with advanced stage II/III multiple myeloma (MM). After autografting with melphalan (200 mg/m2) the patients received after a median interval of 119 days (range 60-210) a dose-reduced regimen consisting of fludarabine (180 mg/m2), melphalan (100 mg/m2), and antithymocyte globulin (3 x 10 mg/kg) followed by allografting from related (n = 7), mismatched related (n = 2), or unrelated (n = 8) donors to induce a graft-versus-myeloma effect. After dose-reduced allografting all patients became neutropenic (< 0.2 x 10(9)/L) for at least 8 days. All patients engrafted with a median time for leukocyte (> 1 x 10(9)/L) and platelet (> 20 x 10(9)/L) counts of 16 (range, 11-24) and 23 days (range, 12-43), respectively. Complete donor chimerism was detected after a median of 30 days (range, 19-38). Acute GVHD stage II occurred in 4 patients (25%) and grade III GVHD in 2 patients (13%). Chronic GVHD developed in 40% of the patients, but only 1 patient experienced extensive chronic GVHD requiring further immunosuppressive therapy. Two patients died of alveolar hemorrhage and pneumonia, resulting in a day 100 mortality rate of 11%. The rate of complete remission with negative immunofixation increased from 18% after autografting to 73% after allografting. After a median follow-up of 17 months after autologous and 13 months after allogeneic transplantation 13 patients are alive and 12 of them free of relapse or progression. The tandem auto-allotransplant protocol is highly active and provides rapid engraftment with complete donor chimerism and tolerable toxicity.

Bendamustine in the treatment of multiple myeloma: results and future perspectives.
    Seminars in oncology, 2002, Volume: 29, Issue:4 Suppl 13

    Multiple myeloma (MM) is a malignancy of terminally differentiated plasma cells typically occurring in elderly patients. The clinical manifestations of this disease result primarily from the accumulation of monoclonal protein (paraprotein) in the serum and/or urine, anemia, lytic bone lesions, hypercalcemia, renal insufficiency, and immune deficiency. Multiple myeloma is incurable with standard chemotherapy. Melphalan and prednisone has been the mainstay of treatment for MM for about three decades. This regimen results in a clinical response in approximately 60% of patients and a median survival of approximately 36 months. A variety of combination therapies have also been used in MM, but have not been considered to offer a significant benefit compared with standard therapy. In early trials, bendamustine monotherapy was as effective as cyclophosphamide and various combination therapies in achieving remission in MM. This article describes a prospective, randomized, phase III study designed to compare the efficacy of bendamustine/prednisolone with a standard melphalan/prednisolone regimen.

VAD followed by VMCP: an alternative regimen for multiple myeloma.
    Medical oncology (Northwood, London, England), 2002, Volume: 19, Issue:2

    In patients with multiple myeloma, a good complete response rate and disease-free survival may be achieved with sequential chemotherapy using VAD and VMCP, which is an alternative effective and less expensive treatment regimen. This regimen thus assumes particular significance in developing nations like India, where the majority of patients with myeloma cannot afford the cost of high-dose chemotherapy with stem cell rescue.

Melphalan-prednisone versus alternating combination VAD/MP or VND/MP as primary therapy for multiple myeloma: final analysis of a randomized clinical study.
    Haematologica, 2002, Volume: 87, Issue:9

    In the absence of a cure for multiple myeloma (MM) with standard-dose therapy, any strategy that can be expected to increase tumor reduction and to extend survival duration is likely to be of clinical relevance. The primary end-point of the present study was to investigate whether the alternating combination of vincristine-doxorubicin-dexamethasone (VAD) and melphalan-prednisone (MP) or vincristine-mitoxantrone-dexamethasone (VND) and MP could improve the clinical outcome of MM patients thus treated in comparison with those receiving MP alone.. Between November 1990 and April 1994, 527 previously untreated, stage I-III, MM patients from 29 Italian institutions were randomized to receive one of three remission induction chemotherapy regimens consisting of 8-monthly courses of either MP alone or alternating VAD/MP or VND/MP.. On an intent-to-treat basis, the objective response rates were 53% with MP (objective + minor: 67%), 47% with VAD/MP (objective + minor: 61%) and 49% with VND/MP (objective + minor: 61%). Median survival duration was 36.5 months with MP, 29 months with VAD/MP and 32.5 months with VND/MP. The difference among these groups was not statistically significant, even after stratifying patients into high-risk and low-risk subgroups, as assessed by a multifactor proportional hazard analysis. In both younger and elderly patients, severe granulocytopenia and related infections were significantly more frequent with VND/MP compared to the remaining arms of treatment (p < 0.001 and p = 0.009, respectively). Similarly, the frequency of WHO grade III-IV cardiovascular events was significantly higher for patients receiving anthracycline-containing regimens (VND/MP and VAD/MP) than for those treated with MP alone (p = 0.04).. Alternating VAD/MP and VND/MP failed to improve the clinical outcome for MM patients, at the cost of increased toxicity and morbidity. Resistance to standard-dose chemotherapy remains a significant obstacle to the treatment of MM.

Fludarabine/melphalan conditioning for allogeneic transplantation in patients with multiple myeloma.
    Bone marrow transplantation, 2002, Volume: 30, Issue:6

    The purpose of the study was to determine the feasibility and efficacy of a reduced intensity conditioning regimen of fludarabine and melphalan for allogeneic transplantation in patients with multiple myeloma. From August 1996 to December 2000, 22 patients received a reduced intensity conditioning regimen with fludarabine and melphalan. Median age was 51 years (range, 45-64), median time from initial therapy to transplant was 36 months (range, 3-135 months). Disease phase prior to transplant was primary refractory in two patients, refractory relapse in 11 patients, sensitive relapse in eight patients and initial remission consolidation in one patient. The median number of prior therapies was five (range, 1-7), and median beta 2 microglobulin prior to transplant was 3.0 mg/l (range, 1.0-7.3). All patients received unmanipulated grafts from either HLA matched sibling donors (n = 13) or matched unrelated donors (n = 9). Eighteen patients received fludarabine 30 mg/m(2) for 4 days with melphalan 140 mg/m(2) as a single dose and four patients received fludarabine 25 mg/m(2) for 5 days with melphalan 90 mg/m(2) daily for 2 days. All 21 patients evaluable for engraftment achieved a neutrophil count of >0.5 x 10(9)/l after a median of 12 days (range, 9-24), 18 patients achieved platelet transfusion independence after a median of 14 days (range, 8-47). All engrafting patients had 100% donor cell engraftment. Seven patients achieved a complete remission. Six patients are currently alive with a median follow-up of 15 months (range, 10-47 months). The actuarial survival and progression-free survival is 30 +/- 11% and 19 +/- 9% at 2 years. Non-relapse mortality at 100 days was 19 +/- 10% and 40 +/- 10% at 1 year. Fludarabine/melphalan combinations are feasible and allow consistent engraftment of allogeneic progenitor cells from both related and unrelated donors in patients with multiple myeloma and should be explored in patients with less advanced disease.

High-dose 166Ho-DOTMP in myeloablative treatment of multiple myeloma: pharmacokinetics, biodistribution, and absorbed dose estimation.
    Journal of nuclear medicine : official publication, Society of Nuclear Medicine, 2002, Volume: 43, Issue:10

    Thirty-two patients with multiple myeloma were treated with high doses of 166Ho-1,4,7,10-tetraazacyclododecane-1,4,7,10-tetramethylene-phosphonic acid (DOTMP) and were a subset of patients enrolled in a multicenter phase I/II dose escalation myeloablative trial. 166Ho with beta-emission (half-life, 26.8 h; beta-particle energies, 1.85 MeV [51%] and 1.77 MeV [48%]; gamma-photons, 80.6 keV [6.6%] and 1.38 MeV [0.9%]) was complexed to DOTMP, a macrocyclic tetraphosphonate. Pharmacokinetics, dosimetry, and biodistribution were studied.. Patients were treated at escalating dose levels of 20, 30, and 40 Gy to the bone marrow in combination with high-dose melphalan, with or without total-body irradiation, to evaluate toxicity and efficacy. After infusion with 1,110 MBq (30 mCi) of 166Ho-DOTMP for evaluation of biodistribution and dosimetry calculation, patients received the calculated amount of radioactivity for therapy in a single administration based on estimated dose calculations.. Thirty-two patients participated in the study and were then treated. The average amount of administered radioactivity was 74.3 GBq (2,007 mCi) (range, 21.5-147.5 GBq [581-3,987 mCi]) of 166Ho-DOTMP.. 166Ho-DOTMP has physical and pharmacokinetic characteristics compatible with high-dose myeloablative treatment of multiple myeloma.

Collection of peripheral blood stem cells in newly diagnosed myeloma patients without any prior cytoreductive therapy: the first step towards an 'operational cure'?
    Bone marrow transplantation, 2002, Volume: 30, Issue:8

    We have shown that primary therapy with non-myeloablative (140 mg/m(2)) high-dose melphalan (HDM) without hematopoietic support results in high response rates in untreated myeloma and very long-term survival of some patients. This study was designed to see if sufficient CD34 (+) cells can be harvested at presentation in newly diagnosed patients to administer myeloablative HDM (200 mg/m(2); HDM200) with autograft as primary therapy. This may improve outcome by rapid achievement of complete remission (CR) and possible avoidance of late myelodysplasia as a consequence of non-transplant induction chemotherapy. Thirty untreated patients received 1 g/m(2) methylprednisolone daily (days 1-6) and 12-16 micro g/kg G-CSF daily (days 3-6), and underwent leukapheresis on days 6 and 7. The median CD34(+) cell yield was 1.31 x10(6)/kg (range, 0.23-5.63), and was > or =1 x10(6)/kg in 73%. Cell yields were significantly lower than in 82 historical controls apheresed after completion of induction chemotherapy (median 2.16 x 10(6)/kg), and improved in patients who were apheresed again after induction chemotherapy. Three patients received primary therapy with HDM200 and autograft using these cells and attained CR. We conclude that it is possible to harvest stem cells in three-quarters of untreated myeloma patients. Increasing the number of apheresis procedures is needed to improve the number of CD34(+) cells collected.

Unrelated stem cell transplantation in multiple myeloma after a reduced-intensity conditioning with pretransplantation antithymocyte globulin is highly effective with low transplantation-related mortality.
    Blood, 2002, Dec-01, Volume: 100, Issue:12

    We investigated the feasibility of unrelated stem cell transplantation in 21 patients with advanced stage II/III multiple myeloma after a reduced-intensity conditioning regimen consisting of fludarabine (150 mg/m(2)), melphalan (100-140 mg/m(2)), and antithymocyte globulin (ATG; 10 mg/kg on 3 days). The median patient age was 50 years (range, 32-61 years). All patients had received at least one prior autologous transplantation, in 9 cases as part of an autologous-allogeneic tandem protocol. No graft failure was observed. At day 40 complete donor chimerism was detected in all patients. Grade II to IV acute graft-versus-host disease (GVHD) was seen in 8 patients (38%), and severe grade III/IV GVHD was observed in 4 patients (19%). Six patients (37%) developed chronic GVHD, but only 2 patients (12%) experienced extensive chronic GVHD. The estimated probability of nonrelapse mortality at day 100 was 10% and at 1 year was 26%. After allografting, 40% of the patients achieved a complete remission, and 50% achieved a partial remission, resulting in an overall response rate of 90%. After a median follow-up of 13 months, the 2-year estimated overall and progression-free survival rates are 74% (95% CI, 54%-94%) and 53% (95% CI, 29%-87%), respectively. A shorter progression-free survival was seen in patients who already experienced relapse to prior autograft (26% versus 86%, P =.04). Dose-reduced conditioning with pretransplantation ATG followed by unrelated stem cell transplantation provides durable engraftment and donor chimerism, reduces substantially the risk of transplant-related organ toxicity, and induces high remission rates.

Response to induction chemotherapy is not essential to obtain survival benefit from high-dose melphalan and autotransplantation in myeloma.
    Bone marrow transplantation, 2002, Volume: 30, Issue:10

    Two hundred and twenty-two myeloma patients autografted after 200 mg/m(2)melphalan were studied to examine the relationship between response to induction chemotherapy and outcome. Induction comprised cyclophosphamide, vincristine, doxorubicin and methylprednisolone (C-VAMP) every 3 weeks for one cycle beyond maximum response. 81% responded to C-VAMP (chemosensitive) with 40 complete (CR) and 139 partial (PR) remissions, and 43 did not respond (NR; <50% reduction in paraprotein; primary refractory). Overall, 130 patients (59%) attained or remained in CR post-transplant; including 40% of NR, 53% of PR, and 97% of CR after C-VAMP (P < 0.0001). Amongst these 130 patients, the 5-year OS was independent of response to C-VAMP (NR 79%, PR 74%, CR 60%; P = 0.69). Similarly, among the 69 patients in PR post-transplant, the 5-year OS was independent of response to C-VAMP. In Cox analysis, lack of response to C-VAMP did not affect outcome significantly. These data show that lack of response to induction therapy does not automatically predict poor long-term outcome in myeloma, since a substantial proportion of these patients attain CR after autograft and enjoy extended survival. Myeloma patients should not be disqualified from an autograft based upon lack of response to induction chemotherapy.

Hepatocyte growth factor in myeloma patients treated with high-dose chemotherapy.
    British journal of haematology, 2002, Volume: 119, Issue:3

    Hepatocyte growth factor (HGF) is a cytokine produced by myeloma cells. We examined serum HGF levels in a population of young myeloma patients (median age 52 years) treated with high-dose chemotherapy. Sera from 128 myeloma patients at diagnosis and serial samples from 16 patients were analysed. Compared with 62 healthy controls, HGF was elevated at diagnosis in 25% of patients (median 0.48 and 1.08 ng/ml respectively; P < 0.0001). The 95 patients who completed therapy were analysed for the impact of HGF on survival. Median survival was not reached after 77 months in the patient group with normal HGF values (< 1.7 ng/ml, n = 69). In the group with elevated HGF (>/= 1.7 ng/ml, n = 26), median survival was 63 months (P = 0.08). In 16 patients, serum was drawn at diagnosis and at the time of expected disease remission (6 weeks to 3 months after chemotherapy). HGF values declined after treatment in 14 of these patients, from a median of 0.9 ng/ml (0.49-1.65) to 0.42 ng/ml (0.32-0.73) (P = 0.005). Our results show that in young myeloma patients HGF is elevated, and that patients with higher levels had a trend towards poorer prognosis. Treatment with high-dose chemotherapy reduced HGF in the serum of the majority of patients.

Amifostine reduces mucosal damage after high-dose melphalan conditioning and autologous peripheral blood progenitor cell transplantation for patients with multiple myeloma.
    Bone marrow transplantation, 2002, Volume: 30, Issue:11

    High-dose melphalan (HDM) has been adopted as standard therapy in the treatment of multiple myeloma. This treatment is associated with non-selective cytotoxicity, causing oral mucositis as the major non-hematological side-effect. Amifostine is a cytoprotector which prevents toxicity induced by anticancer therapy. We prospectively compared two groups of patients who either received (group A, n = 21) or did not receive (group B, n = 20) amifostine (740 mg/m(2)) before HDM (200 mg/m(2)) followed by autologous peripheral blood progenitor cell transplantation. The occurrence of severe oral mucositis was significantly decreased in group A in comparison to group B (33% vs 65%, P < 0.05). Six patients in group A required opioid analgesic therapy during a mean period of 4.8 days as compared to eight patients for 6.5 days in group B (P = NS). Delayed vomiting was less frequent in group A (43% vs 70%, P = 0.07) and significantly less severe in group A (grade 2-4) vomiting: two patients vs nine patients, P < 0.02). No difference was observed between the two groups in either hematological toxicity after HDM or in response rate. Grade I emesis was the only immediate side-effect observed after amifostine administration. We conclude that amifostine can reduce mucositis induced by HDM.

A pilot study on feasibility and efficacy of amifostine preceding high-dose melphalan with autologous stem cell support in myeloma patients.
    Leukemia & lymphoma, 2002, Volume: 43, Issue:10

    To evaluate feasibility and potential efficacy of amifostine (AMI) in the prevention of toxicities associated with high-dose melphalan (MEL), ten myeloma patients received AMI 910 mg/m2 in 15 min infusion preceding MEL 200 mg/m2 followed by stem cell infusion (AMI group). Hematologic and extra-hematologic toxicities as well as the need for supportive care observed in the AMI group were compared with ten myeloma patients treated in an identical protocol but without AMI. Hypotension was the most important adverse event of AMI infusion. No differences were observed in the time of engraftment between the AMI group and the control group neither was there any difference in the need for supportive care. Oral mucositis grade >2 was observed in 30% of the patients in both groups. Diarrhea grade >2 occurred only in two AMI patients but in five control patients. AMI preceding high-dose MEL is feasible, although adverse events are observed in some patients. Whether AMI could reduce the gastrointestinal toxicity associated with high-dose MEL can be reliably assessed only in prospective randomized trials.

Comparison of 200 mg/m(2) melphalan and 8 Gy total body irradiation plus 140 mg/m(2) melphalan as conditioning regimens for peripheral blood stem cell transplantation in patients with newly diagnosed multiple myeloma: final analysis of the Intergroupe Fra
    Blood, 2002, Feb-01, Volume: 99, Issue:3

    High-dose therapy has become a common treatment for myeloma. The objective of this study (Intergroupe Francophone du Myélome [IFM] 9502 trial) was to compare in a prospective and randomized trial the 2 most widely used conditioning regimens before autologous stem cell transplantation in newly diagnosed symptomatic patients younger than 65 years old: 8 Gy total body irradiation plus 140 mg/m(2) melphalan (arm A) versus 200 mg/m(2) melphalan (arm B). A total of 282 evaluable patients were compared--140 in arm A and 142 in arm B. Baseline characteristics and disease response to 4 cycles of the VAD regimen performed before randomization and autologous stem cell transplantation were identical in the 2 treatment arms. In arm B, hematologic recovery was significantly faster for both the duration of neutropenia and thrombocytopenia, transfusion requirements were also significantly lower, and the median duration of hospitalization was significantly shorter. In arm A, the incidence of severe mucositis was significantly increased. The median duration of event-free survival was similar in both arms (21 vs 20.5 months, P =.6), but the 45-month survival was 65.8% in arm B versus 45.5% in arm A (P =.05). This difference might be attributed in part to better salvage regimens after relapse in arm B compared with arm A. We conclude that 200 mg/m(2) melphalan is a less toxic and at least as effective conditioning regimen when compared with 8 Gy total body irradiation with 140 mg/m(2) melphalan. This regimen should be considered as the standard of care before autologous stem cell transplantation in multiple myeloma.

Dose escalation therapy in previously untreated patients with multiple myeloma following Z-Dex induction treatment.
    British journal of haematology, 2002, Volume: 117, Issue:3

    A phase I-II study of high-dose (HD) alkylating agents in newly diagnosed patients with multiple myeloma after maximum response to Z-Dex (idarubicin, dexamethasone) therapy and DHAP (cisplatin, HD cytosine arabinoside, dexamethasone), stem cell mobilization is reported. Twenty-six patients, median age 56 years (range 42-66), completed Z-Dex chemotherapy and peripheral blood stem cells (PBSC) were mobilized with DHAP. Patients then preceded to cyclophosphamide (HD Cy: 6 g/m(2)) with granulocyte colony-stimulating factor followed by busulphan-melphalan-conditioned PBSC autograft. Interferon alpha was introduced at 3 months post transplant as maintenance therapy. Six patients failed to complete the full protocol. Median time from diagnosis to transplantation was 8 months (range 6-12). Mean CD34+ cell dose collected was 15.8 x 10(6)/kg (CI 11.8, 19.8). Median time from DHAP to HD-Cy was 6 weeks (range 4-12) and from HD-Cy to transplant was 8 weeks (range 6-12). The median follow-up was 36 months (range 6-63). On an intent-to-treat basis, the response rates were three complete response (CR, 12%), 21 partial response (PR, 80%) and two stable disease (SD, 8%) post Z-Dex, five CR (19%) and 21 PR (81%) post HD-Cy, and 14 CR (54%) and 12 PR (46%) post transplant. The treatment-related mortality (TRM) was 4% (1 patient). Median overall survival (OS) and progression-free survival (PFS) have not been reached; estimated values were 60 and 48 months respectively. The 3-year OS and PFS were 72% and 62%. Actuarial 5-year OS and event-free survival were 49% and 32%. DHAP produces effective PBSC mobilization and sequential HD therapy, including autologous PBSCT, in patients who received Z-Dex; this offers significant durable disease response rates with acceptable TRM.

Three-step high-dose sequential chemotherapy in patients with newly diagnosed multiple myeloma.
    European journal of haematology, 2002, Volume: 68, Issue:2

    High-dose chemotherapy (HDT) with autologous peripheral blood progenitor cell (PBPC) transplant has been increasingly used for newly diagnosed multiple myeloma (MM) in recent years. Presently available results suggest an improvement in the complete remission rate and survival as compared to conventional chemotherapy. However, there is no plateau in the survival curves, and experiments with new treatment schedules and conditioning regimens are warranted.. In a non-randomised controlled trial, 20 patients underwent three-step HDT following conventional vincristine/doxorubicin/dexamethasone (VAD)-based induction. In the intensification phase patients received high-dose cyclophosphamide (HD-CY), high-dose etoposide (HD-VP), and mitoxantrone (NOV) plus melphalan (L-PAM) with haemopoietic rescue. Maintenance treatment with interferon was given until relapse. Actuarial overall survival (OS) and event-free survival (EFS) curves were plotted according to the method of Kaplan and Meier. In five of the eight patients achieving complete remission (CR), the molecular disease was monitored by polymerase chain reaction technique (PCR).. Overall 18/20 (90%) patients responded, with a CR rate of 40%. After an average follow-up of 40 months, median EFS and OS are 25.5 and 44.6 months, respectively. Monoclonal cells were detectable in the post-treatment bone marrow and in the aphereses of the five CR patients monitored by PCR.. The present three-step HDT regimen, including conditioning with mitoxantrone and melphalan, proved to be feasible and safe. Our results are in agreement with the hypothesis that HDT results in an increased remission rate and in prolonged survival in newly diagnosed MM, but a cure is unlikely.

    The purpose of the study was to evaluate, in a selected group of myeloma patients with favorable prognosis, the effect, on response and survival, of polychymotherapy compared with melphalan prednisone, plus interferon in both arms.. Eighty-nine previously untreated patients with multiple myeloma and prognostic factors indicating a good prognosis were randomized to either oral melphalan plus prednisone (MP) in combination with recombinant interferon-alpha (rIFN-alpha) or combination chemotherapy with vincristine, carmustine, melphalan, cyclophosphamide, and prednisone (VBMCP) alternating with rIFN-alpha. The two treatment groups were comparable in terms of pretreatment characteristics.. The overall response rate was 67.4% (2.3% complete remission, 65.1% partial response) in the MP/IFN-alpha group and 69.1% (14.3% complete remission, 54.8% partial response) in the VBMCP/IFN-alpha group (p=0.59). There were no differences also in response duration and overall survival between the two treatment groups. The median response duration was 39.1 months in the MP/IFN-alpha group and was not reached in the VBMCP/IFN-alpha group (p = 0.6). Overall survival was long in both treatment groups. The estimated 5-yr survival was 66% and 62% in the MP/IFN-alpha and VBMCP/IFN-alpha group, respectively (p=0.8). Toxicity was modest and treatments were well tolerated. Neutropenia (WHO grade 3 or 4) was higher, but not statistically significant, in the VBMCP/IFN-alpha group.. The results of the study show that in myeloma patients with good prognosis, combination chemotherapy alternating with interferon-alpha has no advantage over conventional MP plus interferon-alpha, in regard to response rate, response duration, and overall survival of patients.

Cost-utility analysis of high-dose melphalan with autologous blood stem cell support vs. melphalan plus prednisone in patients younger than 60 years with multiple myeloma.
    European journal of haematology, 2001, Volume: 66, Issue:5

    We evaluated the costs and the cost utility of high-dose melphalan and autologous stem cell support followed by interferon maintenance relative to conventional treatment with melphalan and prednisone, in patients less than 60 yr of age with multiple myeloma. From March 1994 to July 1997, 274 patients with newly diagnosed, symptomatic multiple myeloma were enrolled in a prospective, non-randomized, population-based, multicenter study to evaluate the treatment with high-dose melphalan and autologous blood stem cell support. Health-related quality-of-life was measured prior to treatment and during follow-up, using the EORTC QLQ-C30 questionnaire. Resource consumption was also recorded prospectively. The intensive treatment yielded a significant increase in median survival time from 44 to 62 months compared to conventionally treated patients. The corresponding gain in quality-adjusted life years (QALY) was found to be 1.2. Cost per QALY gained by the treatment with high-dose melphalan and autologous blood stem cell support was estimated at NOK 249,000 (USD 27,000).

High-dose melphalan with G-CSF-stimulated whole blood rescue followed by stem cell harvesting and busulphan/cyclophosphamide with autologous stem cell transplantation in multiple myeloma.
    Bone marrow transplantation, 2001, Volume: 27, Issue:9

    In 90 consecutive patients with multiple myeloma, we investigated the feasibility of administering a tandem high-dose therapy regimen, using whole blood for rescue after the first and leucapheresis harvested between the two high doses, for rescue after the second high dose. After 5 days of G-CSF 1 litre of whole blood (WB) was obtained, left undisturbed at 4 degrees C and reinfused 24 h after HDM (140 mg/m(2)). Patients not in progression after 3-6 months were again mobilised, leucapheresed and treated with busulphan 16 mg/kg and cyclophosphamide 120 mg/kg (Bu/Cy) and reinfusion. In 90 patients, WB contained a mean (range) of 0.57 (0.02-3.22) x 10(6)/kg CD34(+) cells. Recovery after HDM was in 13 days for granulocytes and in 18 days for platelets, with 11 patients not recovering within 3 months. There were three toxic deaths. Sixty-six patients qualified for harvesting after HDM. In the first 11, marrow was harvested. The subsequent 55 patients were mobilised and in 45 the preset minimum of 1.5 x 10(6) CD34(+) cells was obtained. Forty-nine patients actually received Bu/Cy. Recovery after Bu/Cy and marrow reinfusion was in 35 days for granulocytes and 20 days for platelets, with two of five patients not recovering after 3 months. After Bu/Cy and leucapheresis reinfusion, recovery was in 17 days for granulocytes and in 34 days for platelets. Nine patients did not recover within 3 months. There were four toxic deaths. The median overall survival from diagnosis for patients receiving HDM was 49 months and for patients also receiving Bu/Cy, 84 months. We conclude that WB rescue after HDM followed by leucapheresis and a second transplant is feasible in the majority of patients. Better mobilisation techniques are required to increase the number of patients who can receive the second transplant.

Clinical benefits of lenograstim in patients with neutropenia due to chemotherapy for multiple myeloma (MM).
    Supportive care in cancer : official journal of the Multinational Association of Supportive Care in Cancer, 2001, Volume: 9, Issue:5

    The object of this study was to determine the efficacy and safety of glycosylated recombinant human granulocyte colony-stimulating factor (rHuG-CSF; lenograstim) after combination chemotherapy consisting of ranimustine, vindesine, melphalan and prednisolone (MCNU-VMP). One hundred thirty-nine consecutive patients with newly diagnosed multiple myeloma (MM) were allocated at random to a lenograstim group (n = 70) or a placebo group (n = 69). Patients were treated with two cycles of MCNU-VMP, and either lenograstim (2 microg/kg daily, s.c.) or placebo was administered from the day neutrophils decreased to less than 1.000/microl and was discontinued when neutrophils exceeded 5,000/microl. The median duration of neutropenia (neutrophils under 1,000/microl) was significantly shorter for the lenograstim group than the placebo group (2 days vs 9 days in the first cycle; 1 day vs 13 days in the second cycle). The incidence of febrile neutropenia in the first cycle was significantly lower in the lenograstim group than in the placebo group (9.2% vs 30.4%). No life-threatening infections were observed in either group. The two cycles of MCNU-VMP therapy were completed in 90.8% of the patients, and a higher average relative dose intensity (ARDI; 0.94) was achieved in the lenograstim group. The tumor response rate of the lenograstim group (57.8%) was higher than that of the placebo group (43.1%), but the difference was not statistically significant (chi2 = 2.634, df = 1, P = 0.105). Lenograstim was well tolerated, and no unexpected adverse events occurred. Lenograstim proved effective in controlling chemotherapy-induced neutropenia in MM patients under MCNU-VMP therapy.

Health-related quality of life in multiple myeloma patients receiving high-dose chemotherapy with autologous blood stem-cell support.
    Medical oncology (Northwood, London, England), 2001, Volume: 18, Issue:1

    In a population-based study, the Nordic Myeloma Study Group found a survival advantage for high-dose melphalan with autologous blood stem-cell support compared to conventional chemotherapy in myeloma patients under 60 yr of age (risk ratio: 1.62; confidence interval [CI] 1.22-2.15; p = 0.001). A study of health-related quality of life (HRQoL) was integrated in the trial, using the EORTC QLQ-C30 questionnaire. Of the 274 patients receiving intensive therapy 221 (81%) were compared to 113 (94%) of 120 patients receiving conventional melphalan-prednisone treatment. Prior to treatment, there were no statistically significant differences in any HRQoL score between the two groups. One month after the start of induction chemotherapy, the patients on intensive treatment had more sleep disturbance than the control patients. At 6 mo, corresponding to a mean of 52 d after high-dose melphalan, the patients on intensive treatment had moderately lower scores for global QoL and role and social functioning and there was also a significantly higher score for appetite loss. At 12 and 24 mo, the HRQoL was similar to that of the control patients. At 36 mo, there was a trend toward less fatigue, pain, nausea, and appetite loss in the intensive-treatment group. Thus, the 18 mo of prolonged survival seem to be associated with a good health-related quality of life. Despite the moderate HRQoL reduction associated with the early intensive chemotherapy phase, this treatment modality must be regarded as an important step forward in the care of multiple myeloma.

Increased conventional chemotherapy does not improve survival in multiple myeloma: long-term results of two PETHEMA trials including 914 patients.
    The hematology journal : the official journal of the European Haematology Association, 2001, Volume: 2, Issue:4

    Melphalan and prednisone (MP) has been the standard treatment for multiple myeloma (MM) for the last 30 years. Combination chemotherapy at conventional doses has not shown a significant prolongation of survival when compared to MP. There are few data comparing conventional chemotherapy at standard doses with conventional treatment at higher doses. We present the long-term outcome of 914 patients from two randomized trials comparing three different dose intensity regimens.. From 1 January, 1985 to 31 December, 1989, 487 patients were randomized between MP (melphalan 9 mg/m(2) p.o. and prednisone 60 mg/m(2) days 1-4) and alternating VCMP (vincristine 1 mg i.v. on day 1, cyclophosphamide 500 mg/m(2) i.v. on day 1, melphalan 6 mg/m(2) p.o. on days 1-4, and prednisone 60 mg/m(2) on days 1-4) and VBAP (vincristine 1 mg i.v. on day 1, BCNU and doxorubicin 30 mg/m(2) i.v. each on day 1, and prednisone 60 mg/m(2) on days 1-4). From 1 January, 1990 to 31 May, 1994, 427 patients were randomized between VCMP/VBAP at the above detailed doses (VCMP/VBAP 'SD') and the same regimen increasing the doses of cyclophosphamide and doxorubicin from 500 to 1200 mg/m(2) and from 30 to 50 mg/m(2), respectively (VCMP/VBAP 'HD').. Increasing dose intensity produced a significantly higher partial response rate (31% vs 45% vs 51% for MP, VCMP/VBAP 'SD', and VCMP/VBAP 'HD', respectively; P < 0.01). However, a significantly early death rate was observed in the HD arm (7.7, 7.5 and 12.1% for MP, VCMP/VBAP 'SD', and VCMP/VBAP 'HD', respectively; P = 0.05). Median duration of response (20 vs 18 vs 19 months for MP, VCMP/VBAP 'SD', and VCMP/VBAP 'HD', respectively; P = NS) and median survival (25 vs 31 vs 29 months for MP, VCMP/VBAP 'SD', and VCMP/VBAP 'HD', respectively; P = NS) were similar in the three groups. MP produced a higher degree of thrombocytopenia than combination chemotherapy at standard (P = 0.002) or high dose (P = 0.01), this leading to a significantly higher dose reduction in the MP arm (P < 0.001 and P = 0.003 for VCMP/VBAP 'SD' and VCMP/VBAP 'HD', respectively).. In these trials the response rate significantly correlated with the regimen intensity. However, no significant differences in response duration and survival were found. This highlights the limited role of conventional chemotherapy in MM and the need for further trials, aimed at determining the impact of new treatment approaches such as high-dose therapy/autotransplantation.

Serum syndecan-1: a new independent prognostic marker in multiple myeloma.
    Blood, 2000, Jan-15, Volume: 95, Issue:2

    Serum samples drawn at diagnosis from 174 myeloma patients were analyzed for the presence of the heparan [corrected] sulfate proteoglycan, syndecan-1. Syndecan-1 was elevated in 79% of patients (median, 643 units/mL) compared with 40 healthy controls (median, 128 units/mL), P <.0001. Serum syndecan-1 correlated with the following: serum creatinine, secretion of urine M-component over the course of 24 hours, soluble interleukin-6 (IL-6) receptor, C-terminal telopeptide of type I collagen, beta(2)-microglobulin, percentage of plasma cells in the bone marrow, disease stage, and serum M-component concentration. In order to evaluate syndecan-1 as a prognostic marker in multiple myeloma, it was entered into a multivariate Cox regression model. Data from 138 patients were available for this analysis. As a continuous variable, syndecan-1 was an independent prognostic parameter in addition to serum beta(2)-microglobulin and World Health Organization performance status. When syndecan-1 was dichotomized by the best cutoff (66th percentile, 1170 units/mL), the survival difference between the groups was highly significant: "high" syndecan-1 group had a median survival of 20 months, and the "low" syndecan-1 group had a median of 44 months (P <.0001). We conclude that syndecan-1 is a new independent prognostic parameter in multiple myeloma, and its role in prognostic classification systems should be further investigated. (Blood. 2000;95:388-392)

Melphalan plus total body irradiation (MEL-TBI) or cyclophosphamide (MEL-CY) as a conditioning regimen with second autotransplant in responding patients with myeloma is inferior compared to historical controls receiving tandem transplants with melphalan a
    Bone marrow transplantation, 2000, Volume: 25, Issue:5

    The role of more intense conditioning for second transplant was evaluated in myeloma patients achieving at least partial remission (PR) after first transplant with melphalan at 200 mg/m2. Forty-three patients received more intensive conditioning for the second transplant. Nineteen patients received cyclophosphamide 120 mg/kg along with melphalan 200 g/m2 (MEL-CY; group 1) while 24 patients received total body irradiation (1125 cGy) in conjunction with melphalan 140 mg/m2 (MEL-TBI; group 2). Forty-three matched control patients were identified from 450 patients receiving melphalan alone for second transplant (MEL200; group 3). Engraftment and toxicities were comparable among the groups with the exception of increased treatment-related mortality of 8% in group 2 compared to none in groups 1 and 3 (P = 0.07). Despite identical CR rates of 74, 71 and 70%, respectively, in groups 1, 2 and 3 (P = 1.0), event-free survival (median: 27, 15 and 61; P < 0.0001) and overall survival (median: 39, 25 and 76 months; P = 0.003) were significantly decreased in patients receiving more intensive conditioning (groups 1 and 2). Lymphocyte recovery, evaluated as a surrogate for immune recovery, was inferior in more intensively treated patients (groups 1 and 2 compared to group 3). Our findings suggest that more intense conditioning appears to have no benefit in patients responding to their first cycle of high-dose therapy and may even be detrimental in this setting.

The role of autologous transplantation in patients with multiple myeloma aged 65 years and over.
    Bone marrow transplantation, 2000, Volume: 25, Issue:5

    Autologous stem cell transplantation after high-dose melphalan for the treatment with multiple myeloma has resulted in prolonged progression-free survival and overall survival in patients under 65 years. We have examined the role of autologous transplantation in 17 patients with multiple myeloma over 65 years at our centre using a matched pair analysis with younger patients. The median age of this cohort of patients over 65 years was 67 years (65-74) and their outcome and transplant-related morbidity was compared with 17 younger pair mates with a median age of 55 years (31-64). Sixteen patients received high-dose melphalan, and one received busulphan with autologous stem cell rescue. The high-dose therapy was well tolerated in both elderly patients and the matched pairs, with comparable time to recover neutrophils and platelets. Treatment-related mortality also did not differ significantly in both the groups. Median overall survival of the elderly patients was 3.59 years similar to 3.01 years of the pair mates (P = 0.92). Autologous stem cell transplantation after high-dose melphalan conditioning was equally well tolerated in groups of patients above and below 65 years. There was no difference in relapse rate, OS and myelotoxicity in both the groups. These findings suggest that advanced age should not be an exclusion criterion from autologous transplant programmes.

[Clinical evaluation of rhG-CSF in patients with neutropenia induced by chemotherapy for multiple myeloma].
    [Rinsho ketsueki] The Japanese journal of clinical hematology, 2000, Volume: 41, Issue:2

    A randomized controlled study of patients with multiple myeloma was performed to evaluate the efficacy and safety of recombinant human granulocyte colony-stimulating factor (rhG-CSF:KW-2228) in treating neutropenia induced by chemotherapy, and its influence on the dose intensity of, and response rate to, chemotherapy. As a rule, 3 courses of chemotherapy at intervals of 4 weeks were administered both to the untreated and KW-2228-treated groups. Among 98 eligible patients evaluated for neutrophil recovery, a markedly reduced duration of neutropenia was observed during each course in the KW-2228 treated group. No significant difference distinguished the two groups in terms of incidence or duration of infection. However, febrile neutropenia appeared only in the untreated group. There was no significant difference in terms of response rate or dose intensity. However, only patients in the untreated group withdrew from the study due to protracted neutropenia. These results demonstrated that KW-2228 is effective and safe, and has a significant effect on the acceleration of neutrophil recovery in patients with neutropenia induced by chemotherapy for multiple myeloma, and is useful for the completion of chemotherapy regimens.

Long-term survival of stage I multiple myeloma given chemotherapy just after diagnosis or at progression of the disease: a multicentre randomized study. Cooperative Group of Study and Treatment of Multiple Myeloma.
    British journal of cancer, 2000, Volume: 82, Issue:7

    We conducted a randomized trial to evaluate whether melphalan-prednisone (MPH-P) treatment administered just after diagnosis improves survival of stage I multiple myeloma (MM). Between January 1987 and March 1993, 145 consecutive previously untreated patients with stage I MM were randomized between treatment with MPH-P (administered for 4 days every 6 weeks) just after diagnosis and treatment only at disease progression. Survival was not influenced by MPH-P treatment either administered just after diagnosis or at disease progression (64 vs 71 months respectively). Comparing the first with the second group the odds ratio of death is 1.17 (95% confidence interval 0.57-2.42; P = 0.64). Disease progression occurred within a year in about 50% of patients who were initially untreated. Response rate was similar in both groups, but duration of response was shorter in patients who were treated at disease progression (48 vs 79 months, P = 0.044). Patients actually treated at disease progression (34/70) survived shorter than those who had neither disease progression nor treatment (56 vs > 92 months; P = 0.005). Starting MPH-P just after diagnosis does not improve survival and response rate in stage I MM, with respect to deferring therapy until disease progression. However, patients with stage I MM randomized to have treatment delayed and who actually progressed and were treated had shorter survival than those with stable disease and no treatment. Biologic or other disease features could identify these subgroups of patients.

Acute lymphoblastic leukaemia-type intensive chemotherapy to eliminate minimal residual disease after high-dose melphalan and autologous transplantation in multiple myeloma - a phase I/II feasibility and tolerance study of 17 patients.
    Bone marrow transplantation, 2000, Volume: 25, Issue:9

    Aiming to target the minimal residual disease in patients with multiple myeloma, a phase I/II single centre study was undertaken for feasibility and tolerance of intensive acute lymphoblastic leukaemia consolidation chemotherapy (ALL-IC) as part of a strategy for post-transplant consolidation targeted at pre-B cells. Seventeen newly diagnosed patients with myeloma (median age 55 years; 30-65) were initially treated with courses of infused cyclophosphamide, vincristine, adriamycin and methylprednisolone (C-VAMP) followed by melphalan 200 mg/m2(HDM) and peripheral blood stem cell rescue (PBSC). Forty-seven percent were in CR and the rest in PR after HDM. ALL-IC consisted of vincristine, daunorubicin, etoposide, cytarabine, 6-thioguanine and prednisolone given over 5 days. All patients became neutropenic (<0.5 x 109/l) at a median of 10 days (4-18) and one of the 17 patients (5.8%) died 15 days post ALL-IC of sepsis. A further four have died of relapse with an overall survival (OS) of 67% at 4 years. Two of nine patients in PR at the time of ALL-IC achieved CR. Matched-pair analysis of 34 control patients shows no difference for OS and event-free survival between ALL-IC and controls. We conclude that ALL-IC given to myeloma patients after HDM/PBSC is as safe as when used in ALL and warrants further assessment in randomised trials for myeloma.

We now report on continuous CR (CCR) and associated prognostic factors in 1000 consecutive patients receiving melphalan-based tandem HDT. Five-year CCR was 52% among 112 CR patients without chromosome 13 (triangle up13) abnormalities and with beta-2-microglobulin

A combination of anti-interleukin 6 murine monoclonal antibody with dexamethasone and high-dose melphalan induces high complete response rates in advanced multiple myeloma.
    British journal of haematology, 2000, Volume: 109, Issue:3

    To improve the complete response (CR) rate in advanced multiple myeloma (MM) without increasing the toxicity of high-dose therapy, we have used a new conditioning regimen. A combination of BE-8 [an anti-interleukin 6 (IL-6) murine monoclonal antibody] and dexamethasone followed by high-dose melphalan (220 mg/m2) and autologous stem cell transplantation was used to treat a series of 16 patients with advanced multiple myeloma. A strong inhibition of IL-6 activity evaluated by quantification of C-reactive protein was observed in all patients and was correlated with the high CR rate achieved with this combination therapy.

Induction therapy consisting of alternating cycles of ranimustine, vincristine, melphalan, dexamethasone and interferon alpha (ROAD-IN) and a randomized comparison of interferon alpha maintenance in multiple myeloma: a co-operative study in Japan.
    British journal of haematology, 2000, Volume: 109, Issue:4

    This pilot study evaluated the efficacy of a new combination chemotherapy with a newly developed nitrosourea derivative ranimustine and evaluated the efficacy of interferon alpha (IFN-alpha) maintenance in previously untreated patients with multiple myeloma (MM). The induction therapy (ROAD-IN) was a 6-week regimen consisting of chemotherapy with ranimustine, vincristine (Oncovin), melphalan (Alkeran) and dexamethasone starting on day 1 and IFN-alpha, which was administered three times weekly for 3 weeks starting on day 22. This was repeated for three cycles. The responders were subsequently randomized into two groups that received or did not receive IFN-alpha as maintenance therapy. Of the 164 patients registered, 161 were evaluated. An objective response to induction therapy was seen in 75% of patients; complete remission (CR) in 38 (24%) and partial remission (PR) in 82 (51%). The median survival for all patients was 3.6 years from registration. The survival of responders (CR + PR) was significantly better than that of non-responders (median survival 4.3 years vs. 1.4 years; 7-year survival rate 32% vs. 9%; P < 0.0001). The IFN-alpha maintenance did not show any advantage for either response duration or survival. This pilot study demonstrated that a comparatively short period of induction therapy with the ROAD-IN regimen produced a rather high response rate and a similar survival rate to those achieved with other longer induction regimens, and that good responders to the initial therapy survived significantly longer than non-responders.

Gentle yet effective treatment for elderly patients with refractory or relapsing multiple myeloma.
    American journal of hematology, 2000, Volume: 65, Issue:1

    Fourteen patients, aged 65-85 years, with refractory (11) or relapsing (3) multiple myeloma were treated with a "protracted-sequential" protocol comprising vincristine 1-2 mg or vindesine 3 mg/M(2) (max. 5 mg) IVI over 4 hr on D1, prednisolone 40-50 mg PO D1-14, and melphalan 2-4 mg PO or cyclophosphamide 50-100 mg PO D15-28; cycles were repeated at 4-6 weekly intervals. Treatment was continued for 12 months if the response was optimal or indefinitely if the response was suboptimal. Five patients responded optimally; their survival from the commencement of this protocol ranged from 30 to 120 months. The other nine patients achieved a partial response, their survival ranging from 4+ to 79 months. The treatment is simple, nontoxic, and as convenient as the "classic combination" of melphalan and prednisolone.

Thalidomide and its analogs overcome drug resistance of human multiple myeloma cells to conventional therapy.
    Blood, 2000, Nov-01, Volume: 96, Issue:9

    Although thalidomide (Thal) was initially used to treat multiple myeloma (MM) because of its known antiangiogenic effects, the mechanism of its anti-MM activity is unclear. These studies demonstrate clinical activity of Thal against MM that is refractory to conventional therapy and delineate mechanisms of anti-tumor activity of Thal and its potent analogs (immunomodulatory drugs [IMiDs]). Importantly, these agents act directly, by inducing apoptosis or G1 growth arrest, in MM cell lines and in patient MM cells that are resistant to melphalan, doxorubicin, and dexamethasone (Dex). Moreover, Thal and the IMiDs enhance the anti-MM activity of Dex and, conversely, are inhibited by interleukin 6. As for Dex, apoptotic signaling triggered by Thal and the IMiDs is associated with activation of related adhesion focal tyrosine kinase. These studies establish the framework for the development and testing of Thal and the IMiDs in a new treatment paradigm to target both the tumor cell and the microenvironment, overcome classical drug resistance, and achieve improved outcome in this presently incurable disease.

[High-dose melphalan with stem cell support is now an established myeloma therapy. Treatment of myeloma from a 30-year perspective].
    Lakartidningen, 2000, Oct-11, Volume: 97, Issue:41

    Melphalan and prednisone have been the backbone in myeloma therapy for more than 40 years. New developments in chemotherapy and supportive therapy, achieved during the two decades which preceded the use of high-dose chemotherapy with stem cell rescue, have not changed the overall prognosis. A study of high-dose melphalan with autologous stem cell support on 274 patients < 60 years, performed by the Nordic Myeloma Study Group, has shown a prolongation of the median survival by 1.5 years. The results confirm that this therapy is a major step forward in myeloma therapy. Cost-utility and quality-of-life studies show that high-dose therapy has acceptable costs and leads to a favorable long-term quality-of-life.

High-dose idarubicine, busulphan and melphalan as conditioning for autologous blood stem cell transplantation in multiple myeloma. A feasibility study.
    Bone marrow transplantation, 2000, Volume: 26, Issue:10

    Extensive studies have tested the clinical impact of double and triple sequential transplants as front-line therapy in MM, following the suggestion that dose escalation can overcome the marked drug resistance characteristic of this disease, but the superiority of such approaches vs one single transplant has still to be demonstrated. The aim of our study was to evaluate the feasibility and efficacy of high-dose idarubicine intensification of a standard busulphan-melphalan conditioning regimen in MM. Twenty-eight patients (median age 55 years) with sensitive disease received PBSCT after high-dose idarubicine combined with busulphan and melphalan and followed by s.c. rhG-CSF until PMN recovery. The most severe toxicity was represented by oral mucositis which resolved with hemopoietic reconstitution. Overall response and CR rate were 52% and 40%, respectively. Currently, 36 patients are alive and 19 are progression-free a median of 20 months (12-36) from transplant. The 3-year projected probability of progression-free survival for patients transplanted after first-line treatment is 60%. The combination of Ida/Bu/Melph appears a promising alternative regimen for PBSCT in myeloma, with low transplant-related toxicity and fast hematological recovery. Long-term follow-up and a prospective randomized study, now ongoing, will probably clarify whether an idarubicine-intensified regimen will result in superior outcomes to conventional conditioning and even be comparable to a double consecutive transplant program.

Health-related quality of life and patients' perceptions in interferon-treated multiple myeloma patients. Nordic Myeloma Study Group.
    Acta oncologica (Stockholm, Sweden), 2000, Volume: 39, Issue:7

    The effect of interferon on the health-related quality of life in multiple myeloma was assessed in two trials carried out by the Nordic Myeloma Study (Group (NMSG). In both trials, the EORTC QLQ-C30 questionnaire, supplemented with 11 items relating to interferon toxicity, was used. The first was a randomized controlled trial (NMSG 4/90) evaluating the addition of interferon alpha-2b to melphalan and prednisone during induction, maintenance and relapse. During the first 12 months, patients on interferon reported more chills, fever, fatigue, pain, nausea/vomiting, appetite loss and dry skin than the control patients, and a slight reduction of global health and quality of life. From 12 months onward there were no significant differences in any score between the two groups. In a later trial (NMSG 5/94) evaluating the effect of high-dose chemotherapy with stem cell support in patients under 60 years of age with newly diagnosed myeloma, interferon was used as maintenance. During the maintenance phase, symptom and toxicity scores were not significantly different from those in control patients under 60 years of age in the previous trial. Thus, interferon appeared to be well tolerated after high-dose chemotherapy with stem cell support.

Allogeneic haemopoietic stem cell transplantation for multiple myeloma or plasma cell leukaemia using fractionated total body radiation and high-dose melphalan conditioning.
    Acta oncologica (Stockholm, Sweden), 2000, Volume: 39, Issue:7

    We have evaluated the outcome of allogeneic haemopoietic stem cell transplantation for multiple myeloma using a conditioning regimen comprising fractionated total body irradiation and high-dose melphalan (110 mg/m2). The study comprised 25 patients (median age 49 years) who had been transplanted by either bone marrow (n = 13) or G-CSF mobilized peripheral blood stem cells (n = 12). Overall transplant-related mortality was 30% but was lower for patients < 50 years of age at transplant (21%). The main cause of treatment-related mortality was viral infection. Of the 19 patients evaluable post-transplant, 17 have so far achieved complete remissions. Currently, with a median follow-up of 3.4 years, 18 out of 25 patients are alive, of whom 15 are in continuing complete remission (CR) and 2 in second remission after suffering localized relapses, which were treated with radiotherapy and donor leucocyte infusions. Patients transplanted after 1 line of previous therapy, < 50 years of age and receiving peripheral blood stem cells (PBSC) rather than bone marrow (BM) had a superior outcome, although there was no statistically significant factor. We conclude that allogeneic transplantation should be considered as a potentially curative option for younger patients with myeloma and that the regimen using fractionated total body irradiation and melphalan has a high CR rate and a relatively low risk of treatment-related mortality, particularly in younger patients.

OPP-EBV-CAD regimen as salvage treatment in advanced refractory or resistant multiple myeloma.
    Leukemia & lymphoma, 2000, Volume: 40, Issue:1-2

    With the aim of developing an effective therapy for heavily pretreated refractory MM outpatients, we evaluated the OPPEBVCAD regimen, a Hodgkin's disease-derived protocol that includes many drugs effective in MM administered in a sequential schedule. Twenty-two pts aged 42-72 years, with symptomatic highly-pretreated refractory (18 cases), or primary resistant MM (four cases. including two pts with plasma cell leukemia-PCL) received this therapy every 28 days (2-4 cycles, followed by a maintenance program). Therapeutic response (Chronic Leukemia-Myeloma Task Force criteria) and performance status (PS) and pain (W.H.O.) were evaluated. All of the pts were evaluable for response. There were 9 (40%) objective responses (OR: stabilization of blood counts and bone lesions, serum calcium normalization, 50% or more reduction in the concentration of serum monoclonal component (MC), 90% reduction in Bence-Jones proteinuria), 8 (36%) partial responses (PR: 25-50% reduction in serum MC), 1 no response or stable disease (NR), and 4 (18%) cases of progressive disease (PD). OR plus PR were 77%. Of the 4 primary resistant tumors (2 PCL and 2 MM), 2 achieved PR, 1 OR (a PCL case) and 1 progressed. Median survival was 15 months for responding pts (OR plus PR) and 4.5 months for non-responders (NR plus PD). PS and pain improved in 15 pts and did not change in 9. The most frequent side effects were cytopenias, with one drug related infective death. The OPPEBVCAD regimen proved to be an effective therapy for refractory relapsing or primary resistant MM: in responders (two-thirds of the pts), survival was prolonged by about 10 months. Its efficacy in anthracycline-treated pts, as well as the feasibility of using it on an outpatient basis without any continuous drug infusions, make this regimen a promising third line salvage therapy.

Total therapy with tandem transplants for newly diagnosed multiple myeloma.
    Blood, 1999, Jan-01, Volume: 93, Issue:1

    Between August 1990 and August 1995, 231 patients (median age 51, 53% Durie-Salmon stage III, median serum beta-2-microglobulin 3.1 g/L, median C-reactive protein 4 g/L) with symptomatic multiple myeloma were enrolled in a program that used a series of induction regimens and two cycles of high-dose therapy ("Total Therapy"). Remission induction utilized non-cross-resistant regimens (vincristine-doxorubicin-dexamethasone [VAD], high-dose cyclophosphamide and granulocyte-macrophage colony-stimulating factor with peripheral blood stem cell collection, and etoposide-dexamethasone-cytarabine-cisplatin). The first high-dose treatment comprised melphalan 200 mg/m2 and was repeated if complete (CR) or partial (PR) remission was maintained after the first transplant; in case of less than PR, total body irradiation or cyclophosphamide was added. Interferon--2b maintenance was used after the second autotransplant. Fourteen patients with HLA-compatible donors underwent an allograft as their second high-dose therapy cycle. Eighty-eight percent completed induction therapy whereas first and second transplants were performed in 84% and 71% (the majority within 8 and 15 months, respectively). Eight patients (3%) died of toxicity during induction, and 2 (1%) and 6 (4%) during the two transplants. True CR and at least a PR (PR plus CR) were obtained in 5% (34%) after VAD, 15% (65%) at the end of induction, and 26% (75%) after the first and 41% (83%) after the second transplants (intent-to-treat). Median overall (OS) and event-free (EFS) survival durations were 68 and 43 months, respectively. Actuarial 5-year OS and EFS rates were 58% and 42%, respectively. The median time to disease progression or relapse was 52 months. Among the 94 patients achieving CR, the median CR duration was 50 months. On multivariate analysis, superior EFS and OS were observed in the absence of unfavorable karyotypes (11q breakpoint abnormalities, -13 or 13-q) and with low beta-2-microglobulin at diagnosis. CR duration was significantly longer with early onset of CR and favorable karyotypes. Time-dependent covariate analysis suggested that timely application of a second transplant extended both EFS and OS significantly, independent of cytogenetics and beta-2-microglobulin. Total Therapy represents a comprehensive treatment approach for newly diagnosed myeloma patients, using multi-regimen induction and tandem transplantation followed by interferon maintenance. As a result, the proportion of patients

Idiotype vaccination using dendritic cells after autologous peripheral blood stem cell transplantation for multiple myeloma--a feasibility study.
    Blood, 1999, Apr-01, Volume: 93, Issue:7

    The idiotype (Id) determinant on the multiple myeloma (MM) protein can be regarded as a tumor-specific marker. Immunotherapy directed at the MM Id may stem the progression of this disease. We report here on the first 12 MM patients treated at our institution with high-dose therapy and peripheral blood stem cell transplantation (PBSCT) followed by Id immunizations. MM patients received PBSCT to eradicate the majority of the disease. PBSCT produced a complete response in 2 patients, a partial response in 9 patients and stable disease in 1 patient. Three to 7 months after high-dose therapy, patients received a series of monthly immunizations that consisted of two intravenous infusions of Id-pulsed autologous dendritic cells (DC) followed by five subcutaneous boosts of Id/keyhole limpet hemocyanin (KLH) administered with adjuvant. Between 1 and 11 x 10(6) DC were obtained by leukapheresis in all patients even after PBSCT. The administration of Id-pulsed DC and Id/KLH vaccines were well tolerated with patients experiencing only minor and transient side effects. Two of 12 patients developed an Id-specific, cellular proliferative immune response and one of three patients studied developed a transient but Id-specific cytotoxic T-cell (CTL) response. Eleven of the 12 patients generated strong KLH-specific cellular proliferative immune responses showing the patients' immunocompetence at the time of vaccination. The two patients who developed a cellular Id-specific immune response remain in complete remission. Of the 12 treated patients, 9 are currently alive after autologous transplantation with a minimum follow-up of 16 months, 2 patients died because of recurrent MM and 1 patient succumbed to acute leukemia. These studies show that patients make strong anti-KLH responses despite recent high-dose therapy and that DC-based Id vaccination is feasible after PBSCT and can induce Id-specific T-cell responses. Further vaccine development is necessary to increase the proportion of patients that make Id-specific immune responses. The clinical benefits of Id vaccination in MM remain to be determined.

Induction therapy with vincristine, adriamycin, dexamethasone (VAD) and intermediate-dose melphalan (IDM) followed by autologous or allogeneic stem cell transplantation in newly diagnosed multiple myeloma.
    Bone marrow transplantation, 1999, Volume: 23, Issue:4

    We performed a phase II study to test the efficacy and feasibility of induction therapy with vincristine, adriamycin and dexamethasone (VAD) and intermediate-dose melphalan, 70 mg/m2 (IDM), to autologous or allogeneic stem cell transplantation in newly diagnosed multiple myeloma (MM). A total of 77 patients received two cycles of VAD (n = 62) and/or two cycles of i.v. IDM 70 mg/m2 (n = 15) combined with G-CSF. PBSC were harvested after the first IDM, successfully in 87% of patients. Patients with a response to induction received myeloablative therapy with PBSCT (n = 50) followed by IFN maintenance or allo-BMT (n = 11). Seventy-two per cent of patients achieved a response after VAD which increased to 85% after IDM. Of patients who received PBSCT and allo-BMT, 24% and 45% achieved CR, respectively. Toxicity of induction consisted mainly of bone marrow suppression after IDM (median 8 days) with prolonged aplasia in 11% of patients after the second IDM. Only six infections WHO grade 3 occurred during induction. Treatment-related mortality of PBSCT and allo-BMT was 6% and 18%, respectively. Median time of follow-up is 44 months, and 50% of patients after PBSCT and 60% of patients after allo-BMT are still in remission. Survival rates of all patients were 82%, 75% and 63%, and for transplanted patients 86%, 79% and 68% after 12, 24 and 36 months. Well known prognostic factors, including alpha-IFN maintenance after PBSCT, were not significant for response or survival although patients in CR after allo-BMT had a strong tendency for better outcome. VAD/IDM is an effective and safe induction therapy for autologous and allogeneic stem cell transplantation. Based on these observations a phase III trial was started in October 1995 comparing IFN maintenance with PBSCT and allo-BMT after response to induction with VAD and IDM.

Survival in conventionally treated younger (<60 years) multiple myeloma patients: no improvement during two decades. Nordic Myeloma Study Group (NMSG).
    European journal of haematology, 1999, Volume: 62, Issue:4

    The patient registers of five prospective population based Nordic studies were reviewed for patients <60 yr. A total of 313 patients with symptomatic multiple myeloma were identified. Thirty-nine of them were judged retrospectively to have been ineligible for intensive chemotherapy regimens. The remaining 274 patients were considered appropriate as a historical control group for comparison with patients treated with high-dose chemotherapy and autologous stem cell support. Of these, 32 had been diagnosed during the period 1970-83, 101 during the period 1984-89 and 141 during the period 1990-92. The median age was 54 yr. Six percent were Durie/Salmon stage I, 38% stage II and 56% stage III. Melphalan-prednisone was used for initial therapy in 87%. Median survival for all patients with symptomatic myeloma was found to be 41 months, and for those selected for the control group 44 months, with no noted differences between the aforementioned diagnostic periods. We conclude that the expected median survival is 44 months for myeloma patients <60 yr who may be considered for high-dose therapy protocols. New developments in chemotherapy and supportive therapy, achieved during the two decades which preceded the use of high-dose chemotherapy with stem cell rescue, have not changed the overall prognosis in multiple myeloma.

Dose-intensive melphalan with stem cell support (MEL100) is superior to standard treatment in elderly myeloma patients.
    Blood, 1999, Aug-15, Volume: 94, Issue:4

    A clinical relationship between dose-intensity of melphalan and response rate has been demonstrated in multiple myeloma. Promising results have been reported after 200 mg/m(2) melphalan, especially in younger patients. It is uncertain whether 100 mg/m(2) melphalan (MEL100) can offer similar results in older patients. To address this issue, patients were treated with 2 or 3 MEL100 courses followed by stem cell support. Seventy-one patients (median age, 64 years) entered the protocol at diagnosis. Their clinical outcome was compared with that of 71 pair mates (median age, 64 years) selected from patients treated at diagnosis with oral melphalan and prednisone (MP) and matched for age and beta2-microglobulin. Complete remission was 47% after MEL100 and 5% after MP. Median event-free survival was 34 months in the MEL100 group and 17.7 months in the MP group (P <.001). Median overall survival was 56+ months for MEL100 and 48 months for MP (P <.01). In a multivariate analysis, beta2-microglobulin levels and MEL100 were independent risk factors associated with outcome: superior event-free and overall survival were observed in patients presenting low beta2-microglobulin levels at diagnosis and receiving MEL100 as induction regimen. In conclusion, MEL100 was superior to MP in terms of complete remission rate, event-free survival, and overall survival.

The addition of interferon or high dose cyclophosphamide to standard chemotherapy in the treatment of patients with multiple myeloma: phase III Eastern Cooperative Oncology Group Clinical Trial EST 9486.
    Cancer, 1999, Sep-15, Volume: 86, Issue:6

    Interferon (IFN) has demonstrated activity in the treatment of patients with multiple myeloma. A previous Eastern Cooperative Oncology Group (ECOG) study suggested that the rates of complete response (CR) and survival were increased with a regimen that alternated IFN with chemotherapy. The current study was designed to evaluate the effect of adding alternating cycles of IFN or early intensification with high dose cyclophosphamide (HiCy) to the VBMCP regimen for the treatment of multiple myeloma patients.. From February 1988 to May 1992, the ECOG entered previously untreated patients with active multiple myeloma on a study in which they were randomized to VBMCP (vincristine 1.2 mg/m(2) administered intravenously [i.v.] on Day 1, BCNU 20 mg/m(2) i.v. on Day 1, melphalan 8 mg/m(2) administered orally [p.o.] on Days 1-4, cyclophosphamide 400 mg/m(2) i.v. on Day 1, and prednisone 40 mg/m(2) p.o. on Days 1-7; 5-week cycles) or VBMCP + rIFN(alpha2), the latter given at 5 Mu/m(2) 3 times a week starting on Day 22 of each 6-week cycle after 2 initial cycles of VBMCP. Patients younger than 70 years were also randomized to a third treatment that substituted cyclophosphamide 600 mg/m(2) i.v. on Days 1-4 and prednisone 100 mg/m(2) p.o. on Days 1-4 for cycles 3 and 5 of VBMCP (VBMCP + HiCy). Treatment was continued for 2 years.. Of the 653 patients entered, 628 were eligible for the study. All were evaluated for response. With median follow-up for surviving patients of 54 months, the median survival duration was 42 months-1 year longer than usually reported for melphalan combined with prednisone. A comparison of the three regimens revealed no significant difference in the rates of survival or objective response (OR). However, CRs were increased among patients treated with VBMCP + rIFN(alpha2) compared with VBMCP alone (18% vs. 10%, P = 0.03). Patients treated with VBMCP + rIFN(alpha2) had a longer response duration than patients treated with VBMCP alone (30 vs. 25 months, P = 0.035). There was a greater response rate with the IFN regimen among elderly patients (OR and CR = 67% and 31%, respectively) and patients with immunoglobulin A (IgA) myeloma (OR and CR = 83% and 29%, respectively). Severe infections were seen as often with VBMCP as with VBMCP + rIFN(alpha2) (13% vs. 15%), but they were more frequent with VBMCP + HiCy (25%).. VBMCP + rIFN(alpha2) yields a higher rate of CR and a longer response duration than VBMCP alone but appears to make no difference in the rates of overall response or survival compared with VBMCP or VBMCP + HiCy. The superior ability of VBMCP + rIFN(alpha2) induction therapy to produce CR and more durable responses, as well as its activity in older patients and in those with IgA myeloma, suggest that this therapy has important biologic activity in myeloma and merits further clinical investigation.

High-dose melphalan with autotransplantation for refractory multiple myeloma: results of a Southwest Oncology Group phase II trial.
    Journal of clinical oncology : official journal of the American Society of Clinical Oncology, 1999, Volume: 17, Issue:7

    To evaluate high-dose melphalan followed by autologous stem-cell transplantation in patients with refractory multiple myeloma.. Multiple myeloma patients with alkylating agent or vincristine/doxorubicin/dexamethasone-refractory disease were eligible for the phase II multi-institutional Southwest Oncology Group trial S8993. Patients up to age 70 years were enrolled between April 15, 1991, and May 1, 1996. Patients without prior stem-cell collection were primed with high-dose cyclophosphamide (HD-CTX; 6 g/m(2)) and granulocyte-macrophage colony-stimulating factor. After stem-cell procurement, patients received melphalan 200 mg/m(2) with autologous transplantation. Upon recovery from melphalan, patients were to receive interferon alfa-2b until relapse.. Seventy-two patients were enrolled onto S8993; five were ineligible and one received no therapy. Of the 66 assessable patients, 56 patients underwent the transplant procedure; 54 were assessable for response and 56 for toxicity. The response to HD-CTX (n = 37) included three complete remissions (CRs; 8%) and five partial remissions (PR; 14%); response to melphalan (n = 54) included 16 CRs (30%) and 19 PRs (35%), for an overall CR and >/= PR (n = 66; intent-to-treat) of 27% and 58%, respectively. Toxicities included six treatment-related deaths: two during HD-CTX and four during transplantation. The median progression-free survival (PFS) and overall survival (OS) durations on an intent-to-treat basis from transplant registration was 11 months and 19 months (95% confidence interval, 14 to 29 months), respectively. The 3-year actuarial PFS and OS rates were 25% and 31%, respectively.. High-dose therapy with melphalan 200 mg/m(2) is feasible with high response rates (58% overall) and an OS of 19 months in patients with refractory multiple myeloma.

Mature plasma cells as indicator of better prognosis in multiple myeloma. New methodology for the assessment of plasma cell morphology.
    Leukemia research, 1999, Volume: 23, Issue:12

    The relationship between plasmablastic cells and outcome in multiple myeloma (MM) has been established for nearly 15 years. But the assessment of these cells is not easy to perform and it allows the identification of only a small proportion of patients. We investigated the plasma cell morphology using a progressive evaluation of consecutive criteria: nucleolus, chromatin and nuclear-cellular ratio (N/C). The combination of these three items produces a subclassification where four cellular subtypes identify 93% of the plasma cells, and these subtypes are related to the outcome. The interest of this methodology is to be based on the mature plasma cells that are easier to identify than the plasmablastic cells. These new cell subtypes introduce a new classification for patients: Group 1 includes patients with at least 66% mature plasma cells (P000). Both Group 2 and 3 have less than 66% P000 and are separated by their degree of maturation (Proplasma I > or = Proplasma II + plasmablastic). The distinction of these three groups of patients is highly related to the prognosis (P < 10(-4)). These results have been confirmed on a second group of patients coming from a different institution. In conclusion, we propose a new methodology for the plasma cell evaluation in MM, that is based on the morphological criteria and that has the advantage of identifying an intermediate (30%) subgroup of patients with a prognostic significance.

Characterization of autotransplant-related thrombocytopenia by evaluation of glycocalicin and reticulated platelets.
    Bone marrow transplantation, 1999, Volume: 24, Issue:11

    Thrombocytopoiesis of 21 multiple myeloma patients undergoing single or double transplant regimen was characterized by measuring the level of reticulated platelets and plasma glycocalicin. Since reticulated platelets are an index of thrombopoietic activity and glycocalicin plasma values are related to platelet damage and turnover, it may be possible to perform a novel type of analysis of the thrombopoietic compartment during the mobilizing regimen and during transplant-related chemotherapy. Patients underwent mobilizing therapy and first transplant. Some randomized patients also underwent a second transplant with mobilized peripheral blood stem cells. The results show that the percentage of reticulated platelets decreased after therapy and then gradually increased in the recovery phase either during first or second transplant. By contrast, the percentage of reticulated platelets increased until day +8 and then gradually decreased during the mobilizing regimen. The glycocalicin index (glycocalicin plasma value normalized for the individual platelet count) increased significantly both during the course of mobilization and after transplant-related chemotherapy when the platelet number was at its nadir. However, the glycocalicin index was more elevated after transplant-related chemotherapy than after the mobilizing regimen. Our findings suggest that chemotherapy-related thrombocytopenia may be due to a dual mechanism: thrombocytopenia results from decreased platelet production in addition to increased platelet damage and possible destruction.

Alternating combination chemotherapy COP (cyclophosphamide, vincristine, prednisone) and MP (melphalan, prednisone) in multiple myeloma: a multicenter phase II study (JCOG8906). Lymphoma Study Group of the Japan Clinical Oncology Group.
    Japanese journal of clinical oncology, 1999, Volume: 29, Issue:10

    The main form of cytotoxic treatment for multiple myeloma (MM) is conventional dose chemotherapy at present.. Between November 1989 and December 1991, a multicenter phase II study of alternating conventional dose combination chemotherapy (CCT) with COP (cyclophosphamide, vincristine, prednisone) and MP (melphalan and prednisone) to evaluate its clinical usefulness for overt MM patients was conducted by the Lymphoma Study Group of the Japan Clinical Oncology Group (JCOG).. Eighty-one previously untreated patients were enrolled in the study. For 69 eligible patients, the response rate was 50.7% [95% confidence interval (CI) 38.4-63.0%]. The median survival time was 38.5 (95% CI 32.0-44.4) months. The survival rate at 3 and 5 years was 50.7 and 27.3%, respectively. Grade 4 toxicity by the criteria of the World Health Organization consisted of anemia in eight patients, leucocytopenia in three, cardiac in one and hepatic in two, but there was no treatment-related death.. The COP-MP regimen for overt MM is thought to be one of the effective CCTs according to the results of the present phase II study.

Navoban (tropisetron, ICS 205-930) and dexamethasone combination in the prevention of vomiting for patients receiving preconditioning high-dose chemotherapy before marrow transplantation.
    Japanese journal of clinical oncology, 1998, Volume: 28, Issue:2

    The anti-emetic efficacy of a combination of tropisetron and dexamethasone was studied in 33 patients who underwent bone marrow transplantation. Another 50 patients receiving conventional anti-emetic therapies in bone marrow transplantation served as control. On the first and second days of preconditioning chemotherapy, 51% and 36% respectively of patients in the tropisetron and dexamethasone group did not experience vomiting, compared with only 12% and 10% of control group patients (P < 0.001). The mean number of episodes of vomiting in the tropisetron and dexamethasone group was also significantly lower than in the control group (0.97+/-1.65 vs 3.50+/-2.45 and 1.30+/-1.40 vs 4.44+/-2.91 respectively, both P < 0.001). Control of vomiting in the two groups was not significantly different during days 3-6. Analysis of patients receiving busulfan and cyclophosphamide as the preconditioning regimen still showed better anti-emetic control in the tropisetron and dexamethasone group than in the control group on the first two days of treatment (total control rate 33.3% vs 6.5% and 44.4% vs 12.9% respectively, P < 0.001). Patients given tropisetron and dexamethasone combination more frequently suffered from dizziness and burning sensation of the chest. However, diarrhea and extrapyramidal symptoms were the most frequent adverse effects seen after using conventional anti-emetic combination. The combination of tropisetron and dexamethasone was thus superior to conventional anti-emetic combinations in preventing vomiting during preconditioning period of bone marrow transplantation. The adverse effects of this combination were minimal and well tolerated by patients.

Comparable engraftment kinetics following peripheral-blood stem-cell infusion mobilized with granulocyte colony-stimulating factor with or without cyclophosphamide in multiple myeloma.
    Journal of clinical oncology : official journal of the American Society of Clinical Oncology, 1998, Volume: 16, Issue:4

    To compare, in the setting of tandem autotransplantations for multiple myeloma (MM), two established methods of peripheral-blood stem-cell (PBSC) procurement with chemotherapy or hematopoietic growth factor alone.. Between June 1994 and July 1995, 44 patients with MM were randomized to PBSC mobilization with either granulocyte colony-stimulating factor (G-CSF) 16 microg/kg (group 1; n = 22) or high-dose cyclophosphamide (HDCTX) 6 g/m2 plus G-CSF 5 microg/kg (group 2; n = 22). All 44 patients received melphalan 200 mg/m2 with their first autograft and 32 patients proceeded to a second transplantation.. Group 2 required a significantly longer time interval for completion of PBSC collection than group 1 (median, 22 v 8 days; P = .0001), greater frequency of hospitalization (100% v 32%; P = .0001), and increased transfusion of platelets (86% v 18%; P = .0001) and packed RBCs (86% v 55%; P = .02). Likewise, the incidence of fever and pneumonia/sepsis were higher in group 2 (P = .02 and P = .04, respectively). Surprisingly, despite greater CD34 cell quantities infused in group 2, median recovery times of granulocytes (both > 500/microL and 2,500/microL) and platelets (both > 50,000/microL and > 100,000/microL) were similar (all P > .7). Posttransplant toxicities were also similar.. Compared with HDCTX plus G-CSF, high-dose G-CSF alone is associated with lower morbidity, shorter duration of PBSC mobilization, and comparable hematopoietic recovery after transplantation, which should result in significant cost reduction. Considering the relatively limited antitumor activity of HDCTX (10% with > or = 50% tumor cytoreduction), PBSC mobilization with HDCTX should be limited to selected patients with persistent MM despite induction chemotherapy.

Failure of oral pamidronate to reduce skeletal morbidity in multiple myeloma: a double-blind placebo-controlled trial. Danish-Swedish co-operative study group.
    British journal of haematology, 1998, Volume: 101, Issue:2

    In order to study whether oral bisphosphonate therapy might prevent or reduce skeletal-related morbidity in patients with newly diagnosed multiple myeloma who required chemotherapy, 300 patients were included in a randomized multi-centre trial. Patients were given oral pamidronate at a dose of 300 mg daily, or placebo, in addition to conventional intermittent melphalan/prednisolone (and in some cases alpha-interferon) treatment. With a median treatment duration of about 550d, no statistically significant reduction in skeletal-related morbidity (defined as bone fracture, related surgery, vertebral collapse, or increase in number and/or size of bone lesions) could be demonstrated. Pamidronate treatment also did not have any influence on patient survival or on the frequency of hypercalcaemia. However, in patients treated with pamidronate there were fewer episodes of severe pain (P=0.02) and a decreased reduction of body height of 1.5 cm (P= 0.02). The overall negative result of the study is attributed to the very low absorption of orally administered bisphosphonates in general.

Long-term follow-up after high-dose therapy for high-risk multiple myeloma.
    Bone marrow transplantation, 1998, Volume: 21, Issue:11

    Between 1985 and 1990, 133 patients with advanced multiple myeloma (MM) (74% resistance; 41% resistant relapse, RR) were treated with five high-dose therapy (HDT) regimens including: melphalan < or =100 mg/m2 (MEL 100) (46 patients); MEL 100 plus GM-CSF (24 patients); MEL 140 plus autologous bone marrow transplantation (ABMT) (eight patients); MEL 140 plus TBI 850 cGy plus ABMT (37 patients); and thiotepa 750 mg/m2 (THIO 750) + TBI 850 cGy plus ABMT (18 patients). The median follow-up of alive patients as of December 1997 was 9 years. Overall, 17% experienced treatment-related mortality within 60 days (TRM) and 12% achieved stringently defined complete remission (CR) with a median duration of 16 months; four of 16 patients (25%) remain in CR at 10 years. The median durations of event-free survival (EFS)/overall survival (OS) were 6/15 months. Superior EFS/OS were noted with MEL 100 plus GM-CSF and the two TBI-containing regimens (9/24 months among 79 patients) compared to the remaining 54 patients receiving MEL < or =100 or MEL 140 plus ABMT (3/5 months) (P = 0.0001/0.0001, respectively). Multivariate regression analyses (MVA) were performed so that, despite patient heterogeneity among the five treatment groups, potentially relevant disease, host, treatment, and supportive care variables could be identified that were associated with TRM, CR, EFS and OS. TRM was higher with creatinine >2.0 mg/dl, absence of ABMT/GM-CSF support and age >50 years; CR was superior with TBI-containing regimens and < or =12 months of prior therapy; EFS and OS both were longer with B2M < or =2.5 mg/l, age < or =50 years, absence of RR and with ABMT/GM-CSF support. In the presence of >2 favorable variables (32 % of patients), median EFS/OS durations of 18/48 months were observed which progressively declined with 2 and <2 favorable parameters to 6/11 months (28% of patients) to 3/5 months (40% of patients) (P = 0.0001/0.0001). At 10 years, 10 and 20% of patients with >2 favorable variables were event-free and alive, which was also true for the 37 patients receiving MEL 140 plus TBI. To appreciate possible long-term contributions of supportive care or treatment intensity, landmark analyses performed at 1, 2, 4 and 6 months revealed virtually identical ranking orders of prognostically favorable variables to those seen pre-HDT; once supportive care was accounted for, regimen intensity with added TBI did not emerge as an independent favorable feature.

Maintenance treatment with interferon alpha-2b in multiple myeloma: a prospective randomized study from PETHEMA (Program for the Study and Treatment of Hematological Malignancies, Spanish Society of Hematology).
    Leukemia, 1998, Volume: 12, Issue:7

    The objectives of the present study were to investigate whether interferon alpha (IFN) maintenance could prolong response duration and survival in patients with multiple myeloma (MM) in objective response and to analyze the characteristics of relapse and subsequent survival. From January 1991 to November 1994, 92 patients from the Spanish Cooperative Group PETHEMA with MM in objective response after 12 courses of VCMP/VBAP chemotherapy were randomized to receive IFN maintenance vs no treatment until relapse. Prognostic factors at diagnosis were similar in both groups. IFN was administered at a starting dose of 3 mU/m2 three times per week. The IFN toxicity was moderate with granulocytopenia and fatigue being the most common adverse effects. Median duration of response from randomization until relapse was 13 months in the IFN group vs 7.7 months in the no treatment arm (P = 0.042). Median survival from randomization was 38.8 months for patients given IFN vs 32.7 months for those allocated to the no treatment arm (P = 0.12). Features at relapse were similar in patients who received IFN maintenance and in those assigned to no treatment. Finally, survival from relapse was identical in both groups. In summary, our results show a significant prolongation of response in patients maintained with IFN with no significant influence on survival. In addition, in our series features at relapse and subsequent outcome were similar in both groups.

    Polskie Archiwum Medycyny Wewnetrznej, 1998, Volume: 99, Issue:1

    36 MM pts in advanced stage, 17 recently diagnozed (group I) and 19 in the progression of the disease (group II) were examined. 10 pts of group I and 12 of group II had renal failure. Levels of II-6, sII-6R and TNF-alpha were measured in pts sera before cytostatic therapy or plasma exchange (PE) and after 4-week therapy. The plasma concentration of II-6, sIl-6R and TNF-alpha before chemotherapy were 47-426 pg/ml, 33-III ng/ml and 19-350 pg/ml respectively and were significantly higher than in healthy control (group III) but no significant changes were observed between group I and group II. Patients with renal failure showed significantly higher II-6 and sIl-6R plasma levels than those with normal renal function. After 4 weeks of chemotherapy plasma concentration of the examined parameters decreased only in those pts of both groups, who later, after 6 mos disclosed a therapeutic response. Median survival time (m-ST) of recently diagnosed MM pts was 38 mos and in those with progression of underlying disease-43 mos. M-ST of 5 pts whose levels of Il-6 > 150 pg/ml, sIl-6R > 55 ng/ml and TNF-alpha-150 pg/ml was only 18 mos, but when only one of them was so much elevated it attained 55 mos. (p = 0.01).

Successful mobilization of peripheral blood stem cells in heavily pretreated myeloma patients with G-CSF alone.
    Annals of hematology, 1998, Volume: 76, Issue:6

    We investigated the feasibility of mobilizing peripheral blood stem cells (PBSC) with G-CSF alone in 24 patients with multiple myeloma. The median age was 53 years (range 33-62). All patients had stage II/III disease and responded to standard first-line (n = 6) or salvage chemotherapy (n = 18). The median number of previous chemotherapy cycles was 7 (4-18) and the median number of prior melphalan-cycles was 6 (0-14). Nine (35%) patients had experienced prior radiation therapy. The patients received either 10 microg/kg G-CSF (n = 18) or 24 microg/kg G-CSF (n = 7, including one patient with previous 10 microg/kg G-CSF stimulation) daily s.c. for 5 or more consecutive days until completion of harvesting, starting apheresis on the fifth day. G-CSF treatment was well tolerated, with only slight bone pain in half of the patients (51%). After a median of three (range 1-7) apheresis procedures, medians of 3.8 (0.3-17) x 10(6) CD34+ cells/kg, 8.5 (4.5-24) x 10(8) MNC/kg, 2.9 (0.6-39.4) x 10(4) CFU-GM/kg, and 5.6 (0.9-49) x 10(4) BFU-E/kg were harvested. Three patients (12%) with extensive melphalan pretreatment failed the target collection of at least 2.0 x 10(6) CD34+ cell/kg. Pretreatment with six or more cycles of melphalan yielded a smaller number of CD34+ cells than pretreatment with fewer than six cycles (2.5 vs 5.3 x 10(6)/kg; p = 0.001). Nineteen patients underwent high-dose chemotherapy consisting of either total marrow irradiation (9 Gy)/busulfan (12 mg/kg) and cyclophosphamide (120 mg/kg) (n = 10), or busulfan (14 mg/kg)/cyclophosphamide (120 mg/kg) (n = 5), or tandem melphalan (200 mg/m2). The median time for granulocyte (> 1.0/nl) and platelet (> 50/nl) recovery was 10 and 14 days (ranges 7-12 and 8-40), respectively. G-CSF alone is a safe, alternative approach to mobilizing sufficient PBSC in patients with multiple myeloma and allows an exact prediction of harvest time. G-CSF-mobilized PBSCs ensure rapid engraftment after myeloablative therapy. Melphalan treatment should be avoided in patients who are candidates for high-dose chemotherapy.

A randomized trial of maintenance interferon following high-dose chemotherapy in multiple myeloma: long-term follow-up results.
    British journal of haematology, 1998, Volume: 102, Issue:2

    High-dose chemotherapy (melphalan) with autologous marrow stem cell support (AMSCS) results in high response rates in multiple myeloma (MM), with up to 50% of patients achieving complete remission. However, these remissions are generally not durable. As the cytokine interferon alpha has been shown to prolong partial response following conventional chemotherapy, this trial was conducted to evaluate its role following high-dose chemotherapy. 85 patients were randomly assigned to maintenance treatment with interferon alpha, 3 x 10(6) units/m2 subcutaneously three times weekly until relapse or no further treatment following recovery from high-dose chemotherapy (melphalan 140-200 mg/m2 or busulphan 16 mg/kg) combined with AMSCS. At 5.8 years following the accrual of the last patient in this trial, 38 patients had died, 17 in the interferon arm and 21 in the control arm. The median progression-free survival (PFS) in the 42 patients randomized to interferon alpha was 46 months versus 27 months in the controls. Both overall survival and PFS, which were highly significant at median follow-up of 52 months, have now ceased to be significant, because most patients have ultimately succumbed to their disease. Interferon was tolerated by the majority of patients with very good compliance. Toxicity consisted mainly of flu-like symptoms and malaise which were usually self-limiting. The results of such a pilot study should be carefully interpreted and the benefits of interferon should be confirmed in larger multicentre studies in the setting of minimal residual disease following autologous transplantation.

Phase I-II evaluation of rapid sequence tandem high-dose melphalan with peripheral blood stem cell support in patients with multiple myeloma.
    Bone marrow transplantation, 1998, Volume: 22, Issue:3

    This study was designed to determine the maximum tolerated dose (MTD) of high-dose melphalan (HDM), with peripheral blood stem cell support, that could be given twice within 90 days to patients with multiple myeloma. Twenty patients received tandem HDM at 160, 180 or 200 mg/m2 and a total of 55 were treated at the estimated MTD of 200 mg/m2. Seventeen of 55 (31%) did not receive cycle 2; six because of low CD34+ cell yields, three because of severe (n = 1) or fatal toxicities (n = 2) and eight for other reasons. The median interval between doses for 38 patients was 70 days (range 41-225). Three of 55 patients (5%) died of treatment-related causes. In patients completing two cycles of HDM, at any dose level, the complete remission rate improved from 15% following cycle 1 to 55% following cycle 2. The probabilities of survival, event-free survival and relapse or progression at 18 months for the 55 patients treated at the MTD were 0.84, 0.76 and 0.20, respectively, with a median follow-up of 19 months (range 9-36) from mobilization chemotherapy. It was concluded that two cycles of HDM, 200 mg/m2, could be administered to approximately 70% of patients under the age of 66 with multiple myeloma in a median interval of 70 days, with improvement in CR rates.

High-dose therapy and autologous peripheral blood stem cell transplantation in multiple myeloma: up-front or rescue treatment? Results of a multicenter sequential randomized clinical trial.
    Blood, 1998, Nov-01, Volume: 92, Issue:9

    Results to date indicate that high-dose therapy (HDT) with autologous stem cell support improves survival of patients with symptomatic multiple myeloma (MM). We performed a multicenter, sequential, randomized trial designed to assess the optimal timing of HDT and autotransplantation. Among 202 enrolled patients who were up to 56 years old, 185 were randomly assigned to receive HDT and peripheral blood stem cell (PBSC) autotransplantation (early HDT group, n = 91) or a conventional-dose chemotherapy (CCT) regimen (late HDT group, n = 94). In the late HDT group, HDT and transplantation were performed as rescue treament, in case of primary resistance to CCT or at relapse in responders. PBSC were collected before randomization, after mobilization by chemotherapy, and, in the two groups, HDT was preceded by three or four treatments with vincristine, doxorubicin, and methylprednisolone. Data were analyzed on an intent-to-treat basis using a sequential design. Within a median follow-up of 58 months, estimated median overall survival (OS) was 64.6 months in the early HDT group and 64 months in the late group. Survival curves were not different (P = .92, log-rank test). Median event-free survival (EFS) was 39 months in the early HDT group whereas median time between randomization and CCT failure was 13 months in the late group. Average time without symptoms, treatment, and treatment toxicity (TWiSTT) were 27.8 months (95% confidence interval [CI]; range, 23.8 to 31.8) and 22.3 months (range, 16.0 to 28.6) in the two groups, respectively. HDT with PBSC transplantation obtained a median OS exceeding 5 years in young patients with symptomatic MM, whether performed early, as first-line therapy, or late, as rescue treatment. Early HDT may be preferred because it is associated with a shorter period of chemotherapy.

VAD or VMBCP in multiple myeloma refractory to or relapsing after cyclophosphamide-prednisone therapy (protocol MY 85).
    British journal of haematology, 1998, Volume: 103, Issue:2

    263 patients (median age 65+/-10 years) with multiple myeloma were treated with cyclophosphamide-prednisone. Out of this cohort, 103 patients had progressive disease and were randomly assigned to either VAD (vincristine, doxorubicin, dexamethasone; 50 cases) or VMBCP (vincristine, BCNU, cyclophosphamide, melphalan and prednisone; 53 cases). There were no statistical differences between the two groups with the respect to clinical, biological and radiological parameters. There was no difference in survival between the VAD and VMBCP groups. The 4 months response rate was similar in the two groups (50% VAD, 56% VMBCP). With multivariate analysis for survival (Cox model), two factors had a statistically significant impact: Karnofsky index (> 60) and albuminaemia (< 34 g/l). With both Karnofsky index > 60 and albuminaemia > or = 34 g/l, the median survival was 29 months v 2 months with a Karnofsky index < or = 60 and albuminaemia < 34 g/l (P<0.05). In conclusion, VAD or VMBCP had similar activity for salvage treatment in MM refractory or relapsing to first-line treatment with cyclophosphamide-prednisone.

A randomized study comparing VMCP and MMPP in the treatment of multiple myeloma.
    Cancer chemotherapy and pharmacology, 1997, Volume: 39, Issue:4

    To compare VMCP, a multidrug combination chemotherapy comprising vincristine (VCR), melphalan (MPH), cyclophosphamide (CPM) and prednisolone (PSL), with MMPP comprising MPH, ranimustine (MCNU), procarbazine, and PSL as induction, to elucidate the value of alternating combination chemotherapy, and to search for an appropriate maintenance therapy in multiple myeloma.. At 16 institutions in the Nagoya City area, we carried out a randomized trial of VMCP versus MMPP as the initial treatment. Patients who were refractory or resistant to the initial therapy were crossed over into the other arm (crossover trial). For patients who achieved a partial response (PR) or a minor response (MR) and in whom the paraprotein level ceased to decrease, the maintenance therapy was randomized either to an MPH/PSL combination (MP) or to alternating combination therapy (AT) with VMCP and MMPP.. In the 94 evaluable patients of the 111 enrolled, the response rate (PR rate) was 27.7% (13/47) in the VMCP arm and 44.7% (21/47) in the MMPP arm (P = 0.0859). The crossover trial resulted in a PR rate of 15.8% (3/19) for the VMCP-->MMPP crossover and 14.3% (2/14) for the MMPP-->VMCP crossover. The median survival time was 23.4 months for those initially begun in the VMCP arm and 24.9 months for those in the MMPP arm, showing a tendency for better survival during a follow-up of 2-6 years with MMPP treatment, but without statistical significance. The survival time of patients with progressive disease was significantly shorter than that of patients with PR, MR or no change (NC). However, there was no significant difference in the survival rate among those who achieved PR, MR, or NC. As to the maintenance therapy, there was no significant difference in survival between MP therapy and AT. Patients who reached a plateau phase survived significantly longer than those who did not. Except for six cases of grade 3 or 4 neurotoxicity in the VMCP arm, there was no significant difference in the hematologic or gastrointestinal toxicity between the two arms.. We conclude that VMCP is less effective for myeloma than MMPP as the induction treatment, that alternating noncrossresistant chemotherapeutic combinations do not offer an advantage in multiple myeloma, and that patients who reach a plateau phase have a significantly longer survival time.

Prospective randomized placebo-controlled study of granulocyte-macrophage colony-stimulating factor without stem-cell transplantation after high-dose melphalan in patients with multiple myeloma.
    Journal of clinical oncology : official journal of the American Society of Clinical Oncology, 1997, Volume: 15, Issue:2

    To evaluate the impact of granulocyte-macrophage colony-stimulating factor (GM-CSF) or placebo on the durations of intravenous (IV) antibiotic use, hospitalization, neutropenia, and fever, as well as remission rates, after high-dose melphalan (HDM) without stem-cell transplantation (SCT) in patients with multiple myeloma (MM).. One hundred two patients with high-risk MM were randomized 2:1 in a prospective multicenter trial to receive 5 microg/kg/d GM-CSF (69 patients) or placebo (33 patients) starting the day after 140 mg/m2 IV melphalan for up to 21 days.. GM-CSF significantly reduced neutropenia after HDM (median, 23.5 v 29 days; P = .0468), with a trend to reduce the duration of hospitalization (median, 32 v 38 days; P = .0841). Nevertheless, GM-CSF did not significantly reduce infectious toxicity as regards the number of days with fever (median, 5 v 3; P = .359), the number of days with IV antibiotics (median, 22 v 27; P = .14), or early deaths, with an 11.5% treatment-related mortality rate in the GM-CSF group (eight of 69 v two of 32 patients in the placebo group; P = .686). There was no difference in response rates between the two groups of patients.. GM-CSF after HDM without SCT is feasible and significantly shortens neutropenia with a trend toward reduction of hospitalization duration, but does not significantly reduce the morbidity and mortality of such therapy. Thus, when intensive therapy is indicated, given that the mortality of HDM followed by SCT reported in the literature is less than 5% and patients are discharged at approximately day 15, despite the risk of contamination by clonogenic malignant cells, SCT appears to be preferable to GM-CSF after HDM.

Standard therapy versus autologous transplantation in multiple myeloma.
    Hematology/oncology clinics of North America, 1997, Volume: 11, Issue:1

    The IFM 90 trial was designed to compare conventional chemotherapy (CC) and high-dose therapy (HDT). This trial demonstrated a significant superiority of HDT over CC regarding response rate, event-free-survival, and overall survival. Further improvements of HDT can be expected both in terms of feasibility (with the combined use of hematopoietic growth factors and peripheral blood stem cells) and in terms of response rate (using tandem transplants). A substantial improvement in long-term survival, however, will require the development of effective maintenance therapy to control the minimal residual disease present after transplant.

Comparison of melphalan and prednisone with vincristine, carmustine, melphalan, cyclophosphamide, and prednisone in the treatment of multiple myeloma: results of Eastern Cooperative Oncology Group Study E2479.
    Cancer, 1997, Apr-15, Volume: 79, Issue:8

    The Eastern Cooperative Oncology Group (ECOG) performed a Phase III comparison of melphalan and prednisone (MP) with vincristine, carmustine (BCNU), melphalan, cyclophosphamide, and prednisone (VBMCP) in an attempt to determine which of these regimens should be the standard treatment for multiple myeloma.. Four hundred seventy-nine previously untreated patients with multiple myeloma from 23 ECOG institutions were enrolled. Treatment, assigned by randomization, consisted of either 4-week cycles of MP or 5-week cycles of VBCMP. After 1 year of induction therapy, patients received MP or VBMCP maintenance therapy at 6- and 8- week intervals, respectively, until relapse. Patients who experienced treatment failure with MP were eligible for crossover therapy with VBMCP.. Objective responses were obtained for 51% of patients receiving MP, as compared with 72% of patients receiving VBMCP (P < 0.001). Response duration was also longer with VBMCP (median, 18 months with MP vs. 24 months with VBMCP; P = 0.007). Overall survival was not significantly different between MP and VBMCP (P = 0.30). The 5-year survival for VBMCP was 26%, as compared with 19% for MP. VBMCP was associated with more nausea, peripheral nerve toxicity, alopecia, and neutropenia, but the infection rate was equal to that observed with MP. Both regimens were generally well tolerated. The main exception was that elderly patients who were confined to bed had a higher risk of death with VBMCP. The two regimens produced a similar incidence of late secondary myelodysplastic syndrome and acute leukemia. Crossover VBMCP for patients failing with MP was only minimally effective, with an objective response rate of 20% and median survival of 11 months after crossover.. VBMCP is more effective than MP in producing and sustaining remission of multiple myeloma. It is associated with a marginal survival advantage and an apparently greater chance of surviving 5 years for patients who can tolerate moderately intensive combination chemotherapy.

Health-related quality of life assessed before and during chemotherapy predicts for survival in multiple myeloma. Nordic Myeloma Study Group.
    British journal of haematology, 1997, Volume: 97, Issue:1

    Measurement of health-related quality of life was integrated into a randomized trial (NMSG 4/90) comparing melphalan/prednisone to melphalan/prednisone + interferon alpha-2b in newly diagnosed multiple myeloma. One of the aims of the study was to assess the prognostic significance of quality-of-life scores, using the EORTC QLQ-C30 questionnaire. Univariate analysis showed a highly significant association with survival from the start of therapy for physical functioning as well as role and cognitive functioning, global quality of life, fatigue and pain. In multivariate analysis, physical functioning and W.H.O. performance status were independent prognostic factors (P values = 0.001 for both) when analysed in a Cox regression model with the somatic variables beta-2 microglobulin, skeletal disease and age. The best prediction for survival from the start of therapy was obtained by combining the beta-2 microglobulin and physical functioning scores in a variable consisting of three risk factor levels with an estimated median survival of 17, 29 and 49 months, respectively. At a 12 months landmark analysis, the relative risk for patients with physical functioning score 0-20 v 80-100 was 5.63 (99% CI 2.76-11.49), whereas the relative risk for patients without an objective response to chemotherapy compared to those with at least a minor response was 2.32 (99% CI 1.44-3.74). Quality-of-life assessment may be an independent and valuable addition to the known prognostic factors in multiple myeloma.

High-dose therapy with peripheral blood progenitor cell transplantation in multiple myeloma.
    Annals of oncology : official journal of the European Society for Medical Oncology, 1997, Volume: 8, Issue:3

    The objective of our study was to evaluate the efficacy and toxicity of a high-dose melphalan-based (HD-Mel) therapy with or without total body irradiation (TBI) followed by peripheral blood progenitor (PBPC1 transplantation in patients with multiple myeloma (MM).. Between June 1992 and May 1996, 100 patients (67 males 33 females with a median age of 51 years range 30-65) were transplanted at our centre. PBPC were collected during G-CSF-enhanced leukocyte recovery following high-dose chemotherapy. Fifty patients were treated with TBI + melphalan 140 mg m2, while 50 patients received melphalan 200 mg/m2.. Following PBPC autografting, the median time to reach platelets > or = 20 x 10(9) 1 and neutrophils > or = 0.5 x 10(9)/1 was 11 and 14 days with no difference between the treatment groups. In the TBI group significantly longer periods of total parenteral nutrition were required due to severe mucositis. Two patients from the TBI group died due to transplantation-related complications. Following high-dose treatment, remission state improved in 43 out of 98 patients. No statistically significant advantage in reaching CR or PR was observed with TBI + HD-Mel compared to the treatment with HD-Mel alone.. Dose-escalated treatments, with particular regard to the inclusion or omission of TBI, should be prospectively investigated to find the best high-dose regimen.

Factors influencing platelet recovery after blood cell transplantation in multiple myeloma.
    Bone marrow transplantation, 1997, Volume: 20, Issue:5

    We sought to determine factors that impact on the recovery of platelets after blood cell transplantation in patients with multiple myeloma. We performed retrospective analyses in 51 patients undergoing blood cell transplantation for multiple myeloma. The proportional-hazards model was applied to determine significant risk factors. Of 51 transplants, 14 patients failed to achieve a platelet count of 50 x 10(9)/l. Median time to a neutrophil count of 0.5 x 10(9)/l was 10.5 days. Median time to achieve a platelet count of 50 x 10(9)/l was 32 days. Multivariate analysis revealed that cyclophosphamide and G-CSF priming before collection of hematopoietic precursors (P < 0.001) was a positive predictor of rapid engraftment and prior exposure to melphalan given orally (P = 0.02) was a negative predictor of subsequent platelet engraftment. The number of mononuclear cells collected, the patient's disease status at the time of transplant and the presence of circulating plasma cells in the harvested product did not have a significant impact on time to platelet engraftment. We conclude that cyclophosphamide and G-CSF priming shortened the time to achieve platelet engraftment compared with G-CSF alone. Prior exposure to melphalan delayed platelet engraftment and can lead to complete failure of platelet recovery. Stem cells should be collected before melphalan administration in patients with multiple myeloma who are candidates for possible blood cell transplantation.

Transplantation in patients with multiple myeloma: a multicenter comparative analysis of peripheral blood stem cell and allogeneic transplant.
    American journal of clinical oncology, 1997, Volume: 20, Issue:5

    We performed a multicenter comparative analysis of autologous peripheral blood stem cell transplantation (PBSCT) and allogeneic bone marrow transplantation (alloBMT) in multiple myeloma. Forty-eight consecutive patients received either PBSCT (24 patients) or alloBMT (24 patients) at one of three institutions in the study group. Preparatory regimens consisted of melphalan and total body irradiation (TBI) or melphalan alone in the PBSCT group. The alloBMT group received one of four regimens: cyclophosphamide and TBI; cyclophosphamide, VP-16 and 1,3-bis(2-chloroethyl)-1-nitrosourea (CVB); busulfan and cyclophosphamide (BU/CY) and total marrow irradiation (TMI); or melphalan and TBI. Procedure-related mortality was 12.5% for the PBSCT group and 25% for the alloBMT group. With a median follow-up for survivors in the PBSCT and alloBMT groups of 11 months (range, 4-46) and 15 months (range, 2-84 months), respectively, there was no significant difference in median overall survival (33.5 versus 38.6 months, p = 0.7637) or event-free survival (16.7 versus 31 months, p = 0.8450). There was, however, a plateau in survival at 40% in the alloBMT group. No plateau in survival was seen in the PBSCT group. Clinical relapses occurred as late as 39 months posttransplant. Patients have survived up to 28 months postrelapse.

Idarubicin, melphalan and cyclophosphamide: an intensified high-dose regimen for the treatment of myeloma patients.
    Leukemia, 1997, Volume: 11 Suppl 5

    Following conventional chemotherapy, eight myeloma patients presenting with advanced tumor stages were treated with an intensified high-dose regimen and autologous peripheral blood stem cell transplantation. High-dose chemotherapy consisted of idarubicin 20 mg/m2 on days -13, -12 and -11, melphalan 100 mg/m2 on days -5 and -4 and cyclophosphamide 60 mg/kg (plus mesna 60 mg/kg) on days -3 and -2 (IMC). Seven patients achieved a complete remission or a very good partial remission (reduction of M-component > or =90%). There were no toxic deaths. Severe mucositis and fever of unknown origin were seen in all patients. Reversible supraventricular tachycardias without clinical signs of cardiac failure occurred in five patients. One patient developed a persistent deterioration of cardiac function. We surmise that high-dose chemotherapy with IMC is very effective and well tolerated in myeloma patients.

Cost-utility analysis of melphalan plus prednisone with or without interferon-alpha 2b in newly diagnosed multiple myeloma. Results from a randomised controlled trial.
    PharmacoEconomics, 1997, Volume: 12, Issue:1

    This study evaluated the cost utility of adding interferon-alpha 2b to conventional treatment in patients with multiple myeloma. It also provides a methodology for transforming complex quality-of-life profiles into a single index value on the conventional 0 to 1 quality-adjusted life-year scale (QALY). From 1990 to 1992, 583 patients with newly diagnosed, symptomatic multiple myeloma were enrolled in a randomised, multicentre, phase III study to evaluate the addition of interferon-alpha 2b to treatment with melphalan and prednisone. Addition of interferon-alpha 2b yielded a 12% increase in median survival time, at the expense of a slight reduction in quality of life during the first year of treatment. The gain in survival time was not large enough to reach statistical significance. Patients receiving interferon-alpha 2b also had a 5- to 6-month prolongation of the plateau phase. Cost per QALY gained by adding interferon-alpha 2b was conservatively estimated at $US110,000. Potentially better cost effectiveness may be found in different treatment regimens or in certain patient subgroups.

Interferon-alpha 2b added to melphalan-prednisone for initial and maintenance therapy in multiple myeloma. A randomized, controlled trial. The Nordic Myeloma Study Group.
    Annals of internal medicine, 1996, Jan-15, Volume: 124, Issue:2

    To evaluate the addition of low-dose interferon-alpha 2b to standard melphalan-prednisone therapy in patients with multiple myeloma.. Randomized, multicenter, phase III study.. 15 university hospitals and 92 county hospitals in Sweden, Norway, Denmark, Finland, and Iceland.. 583 patients with symptomatic multiple myeloma.. All patients received melphalan-prednisone every 6 weeks. Melphalan-prednisone therapy was interrupted after at least 8 courses in responding patients who achieved a plateau phase, and it was reinstituted at time of relapse. Patients randomly assigned to receive melphalan-prednisone and interferon also received interferon, 5 MU three times weekly, from the start of treatment through response, plateau phase, and relapse, until definitive failure of melphalan-prednisone occurred.. Survival was the main outcome measure. Secondary measures were response rate, response and plateau phase duration, and toxicity. All analyses were done according to the principle of intention-to-treat.. 45% of patients receiving melphalan-prednisone and 44% of patients receiving melphalan-prednisone and interferon achieved at least a partial response. Response duration and plateau phase duration were longer for patients receiving melphalan-prednisone and interferon than for patients receiving melphalan-prednisone alone (P < 0.05); the difference in median duration was 5 to 6 months. Toxicity was higher with melphalan-prednisone and interferon, and this led to premature discontinuation of interferon therapy in one third of patients and to a reduced overall dose intensity for melphalan. The median survival time was 29 months for patients receiving melphalan-prednisone and 32 months for patients receiving melphalan-prednisone and interferon. The risk ratio for death for patients receiving melphalan-prednisone compared with patients receiving melphalan-prednisone and interferon was 1.02 (95% CI, 0.89 to 1.40).. Adding continuous low-dose interferon to standard melphalan-prednisone therapy does not improve response rate or survival. However, response duration and plateau phase duration are prolonged by maintenance therapy with interferon.

Intermediate-dose melphalan (IDM) combined with G-CSF (filgrastim) is an effective and safe induction therapy for autologous stem cell transplantation in multiple myeloma.
    British journal of haematology, 1996, Volume: 92, Issue:1

    Twenty-one previously untreated multiple myeloma (MM) patients and 10 previously treated patients with refractory or relapsed disease received two or three cycles of intermediate-dose melphalan (70 mg/m2) (IDM), administered intravenously every 6 weeks. Seven previously untreated patients received three and all other patients received two courses of IDM. The objective of the study was to reduce the toxicity of high-dose melphalan (140 mg/m2) (HDM) while maintaining its cytotoxic efficacy and secondly to ensure the possibility of collecting sufficient numbers of peripheral blood stem cells (PBSC) for transplantation. 18 (85%) previously untreated patients responded, of whom four achieved CR (18%). In addition five out of 10 previously treated patients with refractory or relapsed disease responded although bone marrow toxicity in this category was a major drawback. Toxicity was moderate, consisting of alopecia and moderate bone marrow suppression: the granulocyte count dropped below 0.5 x 10(9)/l and platelets below 25 x 10(9)/l for a median of 8 and 6 d, respectively. No serious infections occurred and the majority of patients attended the out-patient clinic. In 12/14 previously untreated patients sufficient peripheral blood CD34+ cells for harvest were present in the repopulation phase after the first IDM. In nine patients peripheral blood stem cells were collected and eight patients have undergone successful transplantation. Repeated IDM followed by filgrastim is highly effective in untreated MM and may be safely administered to reduce tumour load prior to PBSC collection. Autologous stem cells harvested after repeated IDM have a full long-term repopulating capacity.

Experience with poorly myelosuppressive chemotherapy schedules for advanced myeloma. The Cooperative Group of Study and Treatment of Multiple Myeloma.
    British journal of cancer, 1996, Volume: 73, Issue:6

    In a multicentre study, 83 patients with advanced and previously uniformly treated multiple myeloma (MM) were randomised between cyclophosphamide (600 mg m-2) and epirubicin (70 mg m-2), administered every 3 weeks for three courses and both associated with prednisone and interferon-alpha2b. Both regimens were administered on an outpatient basis and had low haematological toxicity. Clinical results were similar. Overall response rate (43%) and median response and survival (5.9 and 14.1 months respectively) compare well with those obtained with more aggressive chemotherapy schedules.

Measurement of health-related quality of life in multiple myeloma. Nordic Myeloma Study Group.
    British journal of haematology, 1996, Volume: 92, Issue:3

    When a randomized trial (NMSG 4/90) comparing treatment with melphalan/prednisone to melphalan/ prednisone + interferon alpha-2b in newly diagnosed multiple myeloma was initiated in 1990, a quality-of-life assessment was integrated into the study. We used the questionnaire (QLQ-C30) developed by the European Organization of Research and Treatment of Cancer (EORTC) Study Group on Quality of Life. The QLQ-C30 incorporates five functional scales, three symptom scales, a global health and quality-of life scale and some single symptom measures. The questionnaire was completed prior to treatment and after 1, 6, 12, 24, 36 and 48 months. 524 (90.2%) of 581 patients enrolled in the NMSG 4/90 completed the first questionnaire, and 484 (83.3%) completed all questionnaires given to them. All but one of the scales met the minimum criteria of reliability (Cronbach's alpha >/ 0.70). Validity was shown by (1) the ability of the scales to discriminate clearly between patients differing in clinical status as defined by pretreatment W.H.O. performance index and Durie & Salmon stage, and (2) the sensitivity to changes in objective disease status (response and relapse). This is the first report of the measurement of health-related quality of life in a prospective clinical trial in multiple myeloma. The results demonstrate that the QLQ-C30 is a reliable and valid instrument for the measurement of quality of life in these patients. The data will be used for a cost-utility analysis of the results of the NMSG 4/90 trial.

Evaluation of race as a prognostic factor in multiple myeloma. An ancillary of Southwest Oncology Group Study 8229.
    Journal of clinical oncology : official journal of the American Society of Clinical Oncology, 1996, Volume: 14, Issue:3

    The objective of this investigation was to assess the impact of race (black v white) on the survival of patients with multiple myeloma treated within the context of a large clinical trial.. A cohort of patients randomized to receive one of two treatment regimens and monitored for at least 10 years was studied to assess the impact of race as a prognostic factor, after adjusting for other known factors such as stage of disease. Patients were recruited from the referral network of the Southwest Oncology Group (SWOG), a national multiinstitutional consortium that includes both academic and community treatment centers. Patients had a diagnosis of multiple myeloma and had not previously been treated for this disease. They were carefully characterized as to demographic and clinical features, and were randomized to receive one of two treatment regimens, which proved to have virtually identical outcomes. The outcome measure was survival, measured from the date of randomization to the date of last contact. Patients still alive at last contact date were treated as censored observation.. Survival for black myeloma patients was similar to that for white patients, both overall and adjusted for prognostic factors such as stage.. Observed differences in mortality between blacks and whites cannot be attributed to differences in survival after diagnosis, given comparable treatment.

A prognostic index for multiple myeloma.
    British journal of cancer, 1996, Volume: 73, Issue:9

    The current prognostic systems have failed to identify multiple myeloma (MM) patients who require aggressive therapy. These staging systems do not reliably distinguish patients with different prognoses. This paper explores the possibility of improving the prognostic forecast in MM by considering some clinical characteristics at diagnosis together with response to first-line chemotherapy. A total of 231 patients were prospectively randomised in a multicentre trial to no therapy vs melphalan + prednisone (MP) for stage I, MP in stage II, and MP vs peptichemio, vincristine and prednisone for stage III. The clinical features of these groups were evaluated for prognostic variables predictive of overall survival by means of univariate and multivariate analysis. The independently significant variables were incorporated into a model that identified three groups of patients with different risks of death and different overall survival. Three variables retained statistical significance: the staging system proposed by the British Medical Research Council, a composite parameter integrating the percentage of bone marrow plasma cells with cytological features of the infiltrating elements (plasma cell vs plasmablast), and response to 6 months of first-line chemotherapy. These three variables led the proposal of a scoring system able to identify three different risk classes (with median overall survival of 52, 28 and 13 months respectively) and to estimate individual patient prognosis more flexibly. The proposed risk classes, drawn from both diagnostic and therapeutic parameters, are thought to be a clinical and investigational instrument for separating MM patients into comparable groups, for selecting the best available therapy and for evaluating response with respect to the disease of each new patient.

Autologous peripheral-blood progenitor-cell support following high-dosechemotherapy or chemoradiotherapy in patients with high-risk multiple myeloma.
    Journal of clinical oncology : official journal of the American Society of Clinical Oncology, 1996, Volume: 14, Issue:4

    The aims of the current study were to evaluate in patients with high-risk multiple myeloma (MM) the feasibility and usefulness of high-dose chemotherapy or chemoradiotherapy followed by hematopoietic stem-cell support with autologous peripheral-blood progenitor cells (PBPC) harvested after high-dose cyclophosphamide (HDCYC).. Seventy-three patients with high-risk MM were entered onto the study. Before the procedure, all patients had received HDCYC to collect PBPC by leukapheresis. One patient died of infection after HDCYC. All other patients subsequently received high-dose melphalan (HDM) (140 mg/m2) either alone (n = 1) or associated with either busulfan (16 mg/kg; n = 4) or total-body irradiation (TBI) (8 to 15 Gy; n= 67). In addition, three of the latter patients received cyclophosphamide (120 mg/kg). Thereafter, PBPC were reinfused either alone in 61 patients or together with back-up bone marrow cells in 11 patients in whom the granulocyte-macrophage colony-forming unit (CFU-GM) cell content of the leukapheresis was low.. One patient died of acute cardiac failure after reinfusion of PBPC; three patients did not respond after autologous blood progenitor cell transplantation (ABPCT), while the other 68 patients achieved either a complete response (CR; n = 32) or partial response (PR; n = 36). Thirty-six patients relapsed or progressed after a median response duration of 14.5 months (range, 3 to 43) and 19 of these subsequently died. Four other patients died while still responsive of lung cancer (n = 1) or infection (n = 3). The remaining 28 patients are currently alive and still responding with a median follow-up duration of 27 months (range, 6 to 66). The 3-year probability of survival was 66% +/- 12% (95% confidence interval [CI] after ABPCT and 77% +/- 51% (95% CI) from diagnosis.. High-dose chemotherapy or chemoradiotherapy followed by autologous PBPC support in MM is feasible and efficient. Further studies are needed to confirm these encouraging, although preliminary, results and to compare this technique with other therapeutic strategies.

A prospective, randomized trial of autologous bone marrow transplantation and chemotherapy in multiple myeloma. Intergroupe Français du Myélome.
    The New England journal of medicine, 1996, Jul-11, Volume: 335, Issue:2

    The median survival of patients with myeloma after conventional chemotherapy is three years or less. Promising results have been reported with high-dose therapy supported by autologous bone marrow transplantation. We conducted a randomized study comparing conventional chemotherapy and high-dose therapy.. Two hundred previously untreated patients under the age of 65 years who had myeloma were randomly assigned at the time of diagnosis to receive either conventional chemotherapy or high-dose therapy and autologous bone marrow transplantation.. The response rate among the patients who received high-dose therapy was 81 percent (including complete responses in 22 percent and very good partial responses in 16 percent), whereas it was 57 percent (complete responses in 5 percent and very good partial responses in 9 percent) in the group treated with conventional chemotherapy (P < 0.001). The probability of event-free survival for five years was 28 percent in the high-dose group and 10 percent in the conventional-dose group (P = 0.01); the overall estimated rate of survival for five years was 52 percent in the high-dose group and 12 percent in the conventional-dose group (P = 0.03). Treatment-related mortality was similar in the two groups.. High-dose therapy combined with transplantation improves the response rate, eventfree survival, and overall survival in patients with myeloma.

Survival of multiple myeloma patients who are potential candidates for early high-dose therapy intensification/ autotransplantation and who were conventionally treated.
    Journal of clinical oncology : official journal of the American Society of Clinical Oncology, 1996, Volume: 14, Issue:7

    To analyze the outcome of patients with multiple myeloma (MM) who were potential candidates for early high-dose therapy (HDT) intensification followed by autotransplantation from a series treated with conventional chemotherapy.. From January 1985 through December 1989, 487 patients with symptomatic MM were entered onto a randomized study to compare melphalan and prednisone (MP) versus vincristine, cyclophosphamide, melphalan, and prednisone (VCMP) /vincristine, carmustine (BCNU), doxorubicin, and prednisone (VBAP). The sub-group of 77 patients who could have been candidates for early intensification with HDT followed by stem-cell support (ie, < 65 years of age, stage II or III disease, performance status < 3, and objective or partial response to initial chemotherapy) are the subjects of this report.. Seventy-seven of 487 patients could have been candidates for early intensification. The median age was 56 years (range, 27 to 64). At diagnosis, 12% had abnormal renal function, 16% hypercalcemia, and 42% serum beta 2-microglobulin level > or = 6 mg/L; 62% had stage III disease at diagnosis. Thirty-six patients were initially treated with MP and 41 with VCMP/VBAP. The median response duration to initial chemotherapy was 22 months, and the actuarial probability of being in continued first response at 5 years was 14%. After a median follow-up time of 58 months, 59 patients have died, one was lost to follow-up evaluation, and 17 are still alive 69 to 119 months after initial chemotherapy. The median survival time from initiation of treatment was 60 months and from the time when autotransplantation would be considered, 52 months. The only independent prognostic parameter for survival was renal function at diagnosis.. The median survival time of patients with MM who are less than 65 years of age and who respond to initial chemotherapy is 5 years. This survival duration is similar to that reported in selected series of patients given early HDT and stresses the importance of ongoing randomized trials to determine the role of HDT in the treatment of younger myeloma patients.

Effect of interferon on the health-related quality of life of multiple myeloma patients: results of a Nordic randomized trial comparing melphalan-prednisone to melphalan-prednisone + alpha-interferon. The Nordic Myeloma Study Group.
    British journal of haematology, 1996, Volume: 94, Issue:2

    In a Nordic multi-centre trial, 583 previously untreated multiple myeloma patients were randomized to receive melphalan-prednisone or melphalan-prednisone+ interferon alpha-2b at a dose of 5 million units subcutaneously, 3 d/week. A quality-of-life study was integrated into the trial, using the EORTC QLQ C-30 questionnaire supplemented with 11 questions concerning interferon toxicity. The questionnaire was completed prior to treatment and after 1, 6, 12, 24, 36 and 48 months. 90% of the patients participated in the quality-of-life study, and 83% completed all questionnaires submitted to them. During the first year of treatment the patients on interferon reported significantly more fever, chills, dry skin, fatigue, pain, nausea/vomiting and appetite loss than the control patients. There was a moderate reduction of the global quality-of-life score and slight, non-significant, reductions of physical, emotional, cognitive, social and role functioning scores. After the first year there were no statistically significant differences in any toxicity, symptom or quality-of-life score, except for an increased frequency of dizziness in the interferon group. As only 60% of the patients remained on interferon after 24 months, our data probably underestimate the potential toxicity of the drug. Although there was no significant survival benefit for the interferon patients, a 5-6 months prolongation of the response and plateau phase duration was observed. However, by intention-to-treat analysis, there was no late quality-of-life benefit for the interferon patients to compensate for the early impairment. Thus, the clinical significance of the plateau-phase prolongation is uncertain.

Complete remission induction with combined VBMCP chemotherapy and interferon (rIFN alpha 2b) in patients with multiple myeloma.
    Leukemia & lymphoma, 1996, Volume: 20, Issue:5-6

    The purpose of this study was to evaluate a new regimen for the treatment of multiple myeloma based on alternating 3-week cycles of chemotherapy and interferon (rIFN alpha 2). In this prospective phase II clinical trial the Eastern Cooperative Oncology Group evaluated a regimen consisting of 2 cycles of VBMCP (Vincristine 1.2 mg/M(2) IV d1, BCNU 20 mg/M(2) IV d1, Melphalan 8 mg/M(2) PO dl-4, Cyclophosphamide 400 mg/M2 IV d1, Prednisone 40 mg/M(2) PO d1-7) followed by alternating 3-week cycles of VBMCP and rIFN alpha2 5 Mu/M(2) SC 3x/week. Treatment was administered for 2 years. Fifty-eight patients with previously untreated multiple myeloma were entered. Objective response (OR) required 50% decrease in M-protein with correction of severe anemia and no progression of skeletal disease. Complete remission (CR) was defined by disappearance of M-protein and normalization of the bone marrow morphology. Life table analysis was utilized to express survival and response duration. Fifty-four patients were evaluable. Objective response was seen in 80% of patients including CR in 30% (16 patients). The median response duration is 35 months, 46 months for patients with CR. The median survival is 42 months for all patients. Five year survival is 42%. Although 78% of patients had neutrophil nadirs <1000 x 10(9)/L, the incidence of severe infection was only 9%. These data demonstrate that VBMCP + interferon is an effective new regimen combining chemotherapy with a biological response modifier for the treatment of multiple myeloma. The incidence of CR is high, and the response and survival durations appear to be 1 year longer than usually seen with standard chemotherapy. A current ECOG randomized trial compares VBMCP + interferon with VBMCP alone.

Activating mutations of N- and K-ras in multiple myeloma show different clinical associations: analysis of the Eastern Cooperative Oncology Group Phase III Trial.
    Blood, 1996, Oct-01, Volume: 88, Issue:7

    Mutations of members of the ras family are among the most common oncogene mutations found in multiple myeloma (MM). We have examined the mutational status of the N- and K-ras genes at codons 12, 13, and 61 in 160 newly diagnosed MM patients enrolled on the Eastern Cooperative Oncology Group (ECOG) phase III clinical trial E9486. The total incidence of ras mutations was found to be 39% of the samples analyzed. Five patients showed evidence of more than one mutation. We obtained 22 marrow samples from patients at the time of disease progression or relapse, for whom a ras mutation was identified at diagnosis. In all cases, the ras mutation of the disease progression sample was identical to that found at diagnosis. In contrast, three of 25 patients who did not show any ras mutation at diagnosis acquired a ras mutation at the time of disease progression. No significant association was observed between any ras mutation and stage of disease, beta 2-microglobulin levels, labelling index, or protein type. The mean tumor burden and median survival for patients with mutations of N-ras was indistinguishable from patients with no ras mutations. However, patients with K-ras mutations had a significantly higher mean bone marrow tumor burden at diagnosis than patients with no ras mutations (57% v 36%, P < .02); and the median survival of patients with a K-ras mutation was significantly shorter (2.0 v 3.7 years, P < .02). To determine if the status of ras mutations could affect treatment response, we examined patient survival on the three treatment arms of E9486. Although the presence of a ras mutation in the multidrug treatment, VBMCP alone, showed a marginal significance, neither the VBMCP, nor the addition of interferon-alpha showed statistically significant survival differences between mutant and wildtype ras status. Interestingly, there appeared to be a statistically significant difference in survival of patients treated with VBMCP and alternating high doses of cyclophosphamide + prednisone. Patients with ras mutations had a median survival of 2.1 years; patients with wild-type ras had a median survival of 4.0 years (P < .01).

Maintenance therapy with interferon-alpha (IFN-alpha) versus IFN-alpha plus chemotherapy in multiple myeloma (MM). The Greek Myeloma Study Group.
    European journal of haematology, 1996, Volume: 57, Issue:2

    Results of studies using IFN-alpha treatment for maintaining remission and prolonging survival in multiple myeloma (MM) are in conflict and trials seeking optimum use for this biological response modifier are continuing. Between 1989 and 1993 a prospective randomized multicentre trial was undertaken to evaluate the role of the combination of IFN-alpha with chemotherapy (CT) in maintenance treatment of MM. For remission induction, in patients 65 yr or younger, we used VAD (group A) and for the remaining Melphalan and Prednisone (MP) (group B). For maintenance, patients were randomized to receive IFN-alpha 3 x 10(6) i.u. s.c. t.i.w. (group I) or alternating monthly cycles of IFN-alpha and CT. The CT cycles were also alternated (VAD, MP, CP) in an effort to prevent the development of multidrug resistance. Median survival of the two maintenance groups from randomization (36 months for group I and 31 months for group II, p = 0.3) as well as response duration (13 months in group I and 15 months in group II, p = 0.95) were similar. Toxicities were more pronounced both with VAD induction and in the combination maintenance arm. The addition of chemotherapy to the IFN maintenance regimen in MM did not have an advantage over IFN alone.

Treatment of multiple myeloma in elderly people: long-term results in 178 patients.
    Age and ageing, 1996, Volume: 25, Issue:5

    The purposes of the present study have been to analyse the presenting features, response to therapy and survival of myeloma patients aged 70 years or more, in comparison to younger patients. From January 1985 to December 1989, 487 patients with multiple myeloma (MM) were randomized to receive melphalan and prednisone (MP) versus alternating cycles of vincristine, cyclophosphamide, melphalan, and prednisone (VCMP) and vincristine, BCNU, adriamycin, and prednisone (VBAP). The subset of 178 patients who were 70 or more years is the subject of this study, whereas the 309 patients younger than 70 years were used as a control group. The presenting features and response to chemotherapy of older patients were no different to those of the younger population. However, the survival of elderly patients was significantly shorter (median 23.4 vs. 33.5 months, p < 0.001). The overall response rate to MP in older patients was 50% (28% objective plus 22% partial response) compared with 61% (44% objective plus 17% partial response) to combination chemotherapy (p = not significant). Myelosuppression was moderate in both arms, although MP produced a higher degree of thrombocytopenia. There were no significant differences in survival between patients given MP versus VCMP/ VBAP (median, 20 vs. 27 months, p = 0.2). Response to treatment was associated with a significantly longer survival. Older patients with symptomatic myeloma tolerate chemotherapy and should be offered treatment.

Role of CD34+ cells in engraftment after high-dose melphalan in multiple myeloma patients given peripheral blood stem cell rescue.
    Bone marrow transplantation, 1996, Volume: 18, Issue:5

    During the period December 1992 to June 1995, 95 patients were treated with high-dose melphalan (HDM) with peripheral blood stem cell rescue (PBSCR). Sixty-five had received previous treatment and 28 had relapsed. Among patients who had relapsed 21/28 had received HDM previously including one who received HDM twice during the course of the study. Seventy-five patients were given HDM/PBSCR for the first time. Comparisons have been made between engraftment times for platelets and neutrophils among patients who received less than or greater than 2 x 10(6) CD34+ cells at rescue. Analyses have also been done to evaluate the effect of previous HDM on recovery. Mobilization of progenitor cells was done with granulocyte colony-stimulating factor (G-CSF). Patients received only PBSCR. No growth factors were given to the PBSCR recipients during the recovery period. The percentage of patients from whom the number of CD34+ cells mobilized was > 2 x 10(6)/kg was similar in patients who received HDM for the first time (23%) compared with those who had had it previously (19%). The yield of CD34+ cells correlated with the number of granulocyte-macrophage colony forming units (CFU-GM). Although the number of CD34+ cells infused was < 2 x 10(6)/kg in 77% of patients, all engrafted for neutrophils to > 0.5 x 10(9)/l. This was delayed in patients who had had previous HDM (P < 0.02). Platelet recovery to > 25, 50 and 100 x 10(9)/l was delayed in all patients who received < 2 x 10(6) CD34+ cells/kg infused (P < 0.02). In patients who had had previous HDM both neutrophil (P < 0.05) and platelet recovery (P < 0.007) were delayed compared with recovery in patients who had not had HDM. In patients who had had previous HDM and received < 2 x 10(6) CD34+ cells/kg infused only 3/17 regained platelets to > 100 x 10(9)/l compared with 3/4 who had > 2 x 10(6) CD34+ cells/kg infused (P < 0.05 Fisher's exact test). There was no evidence that low numbers of CD34+ cells in the PBSCR were associated with early death. The data show that previous treatment with HDM had adverse effects on the subsequent engraftment of platelets among patients given HDM/PBSCR. The data suggest that additional measures are needed to achieve platelet reconstitution in these heavily pre-treated patients.

High-dose melphalan with re-infusion of unprocessed, G-CSF-primed whole blood is effective and non-toxic therapy in multiple myeloma.
    European journal of cancer (Oxford, England : 1990), 1996, Volume: 32A, Issue:12

    In order to shorten the pancytopenic period following high-dose melphalan 140 mg/m2 (HDM) treatment of multiple myeloma patients, we studied the effects of re-infusing granulocyte colony stimulating factor (G-CSF) [Filgrastim, Neupogen]-primed unprocessed whole blood. 30 patients with multiple myeloma were treated with HDM. One litre of blood after 5 or 6 days stimulation with G-CSF (10 micrograms/kg) was drawn, kept unprocessed for 1 day and re-infused 24 h after chemotherapy. Time to granulocyte recovery (> 0.5 x 10(9)/1) and platelet recovery (> 20 x 10(9)/1) were assessed as well as length of hospital stay, number of transfusions and antibiotic use. These 30 patients were compared with 20 historical control patients who were similarly treated but without stem cell support. The response rate was 75% (21/28) including a complete remission (CR) rate of 29% (8/28). Two early deaths due to Aspergillus pneumonia were observed. The median overall survival after HDM has not been reached after a median follow-up of 14 months. 10 patients showed progression at a median of 7 months. Currently, 23 patients are alive with a median follow-up time of 14 months. Haematological recovery was significantly faster in the study group as compared to the historical control group. The neutrophil count reached 0.5 x 10(9)/1 at a median of 14 days after infusion of 1 litre of unprocessed whole blood compared with 38 days in the historical control group. A platelet count of 20 x 10(9)/1 was reached at a median of 26 days compared with 36 days in the historical control group. Length of hospital stay decreased from a median of 43 to 18.5 days. The number of days with antibiotics was reduced from a median of 21 to 6 days. HDM is effective therapy for multiple myeloma. Toxicity of the regimen is considerably reduced by the use of G-CSF-stimulated unprocessed whole blood, an easy to perform and cheap technique to mobilise and collect stem cells.

Improved outcome in solitary bone plasmacytomata with combined therapy.
    Hematological oncology, 1996, Volume: 14, Issue:3

    Solitary bone plasmacytoma (SBP) is a rare presentation of plasma cell dyscrasias. Radiotherapy has been considered the treatment of choice, however, most patients will develop multiple myeloma, 3 to 10 years after initial diagnosis and treatment. No innovations have been introduced in the treatment of SBP in the last 30 years. We began a prospective clinical trial to assess the efficacy and toxicity of adjuvant chemotherapy with low doses of melphalan and prednisone administered to patients with SBP after radiation therapy in an attempt to improve the disease-free survival and overall survival. Between 1982 and 1989, 53 patients with SBP were randomly assigned to be treated with either local radiotherapy with doses ranged from 4000 to 5000 cGy to achieve local control of disease (28 patients) or the same radiotherapy schedule followed by melphalan and prednisone given every 6 weeks for 3 years (25 patients). After a median follow-up of 8.9 years, disease-free survival and overall survival were improved in patients who were treated with combined therapy, 22 patients remain alive and free of disease in the combined treatment group compared to only 13 patients in the radiotherapy group (p < 0.01). Treatment was well tolerated; planned doses were administered in all cases; no delays in treatment or acute side-effects were observed during treatment. Long-term secondary toxicities including secondary neoplasms and acute leukaemia, have not been observed. We felt that the use of adjuvant chemotherapy after adequate doses of radiotherapy in patients with SBP improved duration of remission and survival without severe side-effects. However, as with other studies in SBP, the group was too small to draw definitive conclusions and more controlled clinical trials are necessary to define the role of this therapeutic approach in patients with SBP.

Comparison of interferon tolerance after autologous bone marrow or peripheral blood stem cell transplants for myeloma patients who have responded to induction therapy.
    Leukemia & lymphoma, 1996, Volume: 21, Issue:5-6

    Interferon (INF) has been incorporated as part of maintenance therapy after high dose treatment in order to make remissions more durable. In this study we have compared peripheral blood stem cell transplant (PBSCT) versus autologous bone marrow transplant (ABMT) with respect to INF tolerance. Thirty nine PBSCT patients have been compared to 37 ABMT patients for INF tolerance. This is followed by a comparison of 15 PBSCT patients versus 21 ABMT patients for engraftment details, response and survival. INF was started at a median of 61 days in the PBSCT and 58 days in the ABMT patients (P = NS). It was well tolerated in both groups without a significant difference in toxicity in the two arms. Engraftment was more rapid in the PBSCT patients with platelet recovery being significantly faster. Response and survival showed a favourable trend for ABMT patients though statistical significance was not reached and the cost of PBSCT was 12% cheaper. We were thus able to conclude that PBSCT grafts were as durable and could tolerate INF just as well as ABMT. Engraftment was more rapid and the procedure of PBSCT was also cheaper. Further studies with a larger group of patients will be required before comments on the efficacy of treatment can be made.

Immunoreactive interleukin-6 and acute phase proteins as prognostic factors in multiple myeloma. Finnish Leukemia Group.
    Blood, 1995, Feb-01, Volume: 85, Issue:3

    High serum level of bioactive interleukin-6 (IL-6) is regarded as a predictor of poor prognosis in multiple myeloma (MM). On the other hand, the reported levels of immunoreactive IL-6 have been highly variable, and the prognostic value of immunoreactive IL-6 in MM is not clear. We have analyzed the prognostic significance of serum immunoreactive IL-6, as measured by a sensitive immunosorbent assay, in 210 patients with newly diagnosed MM subsequently treated with intermittent melphalan and prednisone. The serum levels of acute phase proteins C-reactive protein (CRP), alpha 1-antitrypsin (alpha 1AT), and acid alpha 1-glycoprotein (orosomucoid; OM) were evaluated as surrogates for IL-6. Serum IL-6, CRP, alpha 1AT, and OM levels were raised in 42%, 40%, 41%, and 24% of the patients, respectively. There was a significant correlation between the clinical stage of the patients and serum IL-6 (P = .006), alpha 1AT (P = .001), and OM (P = .004) levels at diagnosis. At 3 years, 52% of the patients were alive. Univariate logistic regression analysis showed that high levels of IL-6 (P = .002), CRP (P = .02), alpha 1AT (P < .001), OM (P = .007), beta 2-microglobulin (beta 2M; P < .001), and thymidine kinase (P < .05) were all associated with 3-year mortality. In multivariate regression analysis, beta 2M (P < .0001) and alpha 1AT (P = .01) had independent prognostic significance. The patients with high levels of both beta 2M and alpha 1AT or IL-6 were at very high risk of dying within 3 years from diagnosis (16% and 21% of the patients in these groups were alive, respectively). When the patients were stratified according to the clinical stage, the prognostic significance of serum IL-6 and alpha 1AT was especially evident in stage II patients. When the patients were divided into two groups according to normal or raised serum IL-6 levels, the patients with high IL-6 levels had more frequent osteolytic bone lesions (P = .03) and a more aggressive disease. We conclude that serum immunoreactive IL-6 is a significant prognostic marker in MM.

G-CSF is a major component of colony-stimulating activity (CSA) in the plasma of patients with multiple myeloma after treatment with high-dose melphalan (HDM).
    Experimental hematology, 1995, Volume: 23, Issue:4

    Colony-stimulating activity (CSA) was measured by the production of granulocyte-macrophage colony-forming units (GM-CFU) from normal donor bone marrow in the plasma of 29 patients with multiple myeloma (MM) after intensive treatment with high-dose melphalan (HDM) with or without autologous bone marrow rescue (ABMR). Although patients who received ABMR had an earlier recovery of circulating neutrophils compared with those who received HDM alone, the time at which CSA reached a maximum was similar in both groups (10 to 11 days) after therapy. The decline in CSA correlated with the recovery of the neutrophil count. In plasma from patients who received recombinant human granulocyte colony-stimulating factor (rhG-CSF), in addition to an autograft, CSA reached a maximum earlier (7 days). Furthermore, neutrophil recovery was earlier in these patients. Platelet recovery was not increased by rhG-CSF. The time at which CSA was maximum in four patients who were undergoing intensive therapy for the second time occurred 9 days after treatment with HDM. Although the period without neutrophils was longer in three (of four) patients who survived long term, one patient who received rhG-CSF had a shorter period of neutropenia than the two who had not had the cytokine. G-CSF was detected in plasma from seven of seven patients but not at all times after treatment. In plasma samples that contained G-CSF, colony numbers were increased by recombinant interleukin-4 (rIL-4) in vitro. Neither IL-3 nor GM-CSF was detected in plasma; however, antibody to GM-CSF reduced CSA in all samples after intensive therapy. The data suggest that CSA is a consistent physiologic response to intensive therapy, even in previously treated patients, but that hematologic recovery is dependent on the availability of viable progenitor cells.

Retrovirally marked CD34-enriched peripheral blood and bone marrow cells contribute to long-term engraftment after autologous transplantation.
    Blood, 1995, Jun-01, Volume: 85, Issue:11

    We report here on a preliminary human autologous transplantation study of retroviral gene transfer to bone marrow (BM) and peripheral blood (PB)-derived CD34-enriched cells. Eleven patients with multiple myeloma or breast cancer had cyclophosphamide and filgrastim-mobilized PB cells CD34-enriched and transduced with a retroviral marking vector containing the neomycin resistance gene, and CD34-enriched BM cells transduced with a second marking vector also containing a neomycin resistance gene. After high-dose conditioning therapy, both transduced cell populations were reinfused and patients were followed over time for the presence of the marker gene and any adverse effects related to the gene-transfer procedure. All 10 evaluable patients had the marker gene detected at the time of engraftment, and 3 of 9 patients had persistence of the marker gene for greater than 18 months posttransplantation. The marker gene was detected in multiple lineages, including granulocytes, T cells, and B cells. The source of the marking was both the transduced PB graft and the BM graft, with a suggestion of better long-term marking originating from the PB graft. The steady-state levels of marking were low, with only 1:1000 to 1:10,000 cells positive. There was no toxicity noted, and patients did not develop detectable replication-competent helper virus at any time posttransplantation. These results suggest that mobilized PB cells may be preferable to BM for gene therapy applications and that progeny of mobilized peripheral blood cells can contribute long-term to engraftment of multiple lineages.

Patient accrual and quality of participation in a multicentre study on myeloma: a comparison between major and minor participating centres.
    British journal of haematology, 1995, Volume: 91, Issue:1

    The participation of minor centres in randomized trials has been questioned because of inferior quality of participation. We have studied this issue in a multicentre trial on myeloma, in which 574 patients were included from 99 participating centres in Sweden, Norway and Denmark from 1 June 1990 until 4 November 1992. Two hundred and eight patients were entered from university hospitals (n = 13), 172 from major county hospitals (n = 25), defined by a population base of > or = 100,000 inhabitants, and 194 from minor county hospitals (n = 61) with a population base of < 100,000 inhabitants. The accrual rate was similar for the three hospital categories, averaging 54% of all reported cases, corresponding to 38% of the expected number of newly diagnosed cases. The adherence to the study protocol from an administrative point of view was judged by the completeness of follow-up forms and the delay in the notification of deaths, and from a clinical point of view by the dose intensity for the principal drugs of the study, melphalan and interferon. For all studied measures of quality, the values were similar for the three hospital categories. We conclude that with due informative and educational support, minor centres can make a considerable contribution to the patient material of a large randomized trial without impairing the quality of the study.

    The expression of the Bcl-2 oncoprotein was studied in pre-treatment bone-marrow samples from 63 patients with multiple myeloma, using an immunohistochemistry technique. A variable expression of the Bcl-2 protein was found in myeloma cells. 43% of the patients had strong expression of the Bcl-2 protein in the malignant cells. Forty patients received alpha-interferon, whereas 23 patients received melphalan/prednisone therapy. A significant association (p = 0.012) was found between high levels of Bcl-2 expression in myeloma cells and resistance to interferon therapy. No such correlation was found in the melphalan/prednisone treated patients. The data indicate that over-expression of Bcl-2 may be a cause for resistance to interferon therapy in myeloma and that staining for Bcl-2 expression in myeloma cells may have a predictive value for this treatment.

Interferon-alpha-2b with VMCP for induction in multiple myeloma: the Israel Myeloma Cooperative Group experience.
    Israel journal of medical sciences, 1995, Volume: 31, Issue:10

    In 1988, a prospective, randomized multicenter study was initiated to determine the efficacy of a combined induction regimen with recombinant interferon-alpha-2b (IFN-alpha) and maintenance with IFN-alpha on the response and survival rates in multiple myeloma (MM) patients. Induction therapy consisted of VMCP (vincristine, melphalan, cyclophosphamide, prednisone), randomized to combine IFN-alpha at a dose of 2 x 10(6) U, 5 days per week throughout the induction period of 12 months. Patients who achieved plateau phase were subsequently randomized again between IFN alpha maintenance (2 x 10(6) U, 3 days a week) for 12 months and no maintenance therapy. Of the previously untreated patients, 84 were initially randomized for induction therapy, and 31 for the maintenance phase with IFN-alpha. Results of the cohort median survival, based on the intention to treat, have shown that those on the VMCP/IFN-alpha arm had a median survival of 53 months, compared with patients on the VMCP induction arm who a median survival of 26 months (P = 0.052). The median survival of stage 3 evaluable patients who were on the VMCP/IFN induction arm was 43 months, and 13 months for patients treated by VMCP alone (P = 0.008). No significant difference in survival was detected among patients in partial remission (after induction) who had a second IFN-alpha randomization at the plateau phase. Hematologic toxicity, mild to moderate fever, and fatigue were more common in the VMCP/IFN induction arm. The results show that VMCP/IFN is a well-tolerated treatment regimen, and is superior to VMCP for patients with stage 3 myeloma.

Development of a criterion for response to therapy at 6 months in multiple myeloma.
    European journal of haematology, 1995, Volume: 55, Issue:2

    To investigate the prognostic value of therapy at 6 months on survival in multiple myeloma, to develop a new criterion assessing response to initial therapy at 6 months, and to compare it to a current criterion. The types of initial and 6-month therapy were considered in a prognostic factor analysis in 70 patients treated in routine practice. Using the response to initial therapy defined by the clinician's decision as grouping variable in this group, a discriminant analysis identified the characteristics of responder patients. The validity of the resulting criterion was tested in another test group. Its prognostic ability was compared to the CLMTF criterion (50% M-component reduction from baseline). The therapy at 6 months, reflecting the clinician's appraisal of response to initial therapy, predicted survival significantly. A criterion combining two variables (M-component change and haemoglobin level at 6 months) classified 70% and 72.4% of patients correctly regarding response status in the training and test groups respectively. This criterion was shown to perform better than the CLMTF criterion in predicting survival.. A new criterion for response to therapy at 6 months, also presented in a nomogram, combines M-component change and haemoglobin level at 6 months.

Randomized trial of interferon maintenance in multiple myeloma: a study of the National Cancer Institute of Canada Clinical Trials Group.
    Journal of clinical oncology : official journal of the American Society of Clinical Oncology, 1995, Volume: 13, Issue:9

    To determine whether interferon maintenance therapy improves overall survival and response duration in patients with multiple myeloma who have responded to induction therapy with melphalan and prednisone.. In a multicenter trial, patients with symptomatic clinical stage I and stage II and III multiple myeloma were registered at diagnosis and those who responded to melphalan-prednisone (MP) were randomized either to receive interferon (2 mU/m2) subcutaneously three times per week or no maintenance. MP was discontinued in both groups once a stable response plateau of the monoclonal protein was reached. Interferon was continued until relapse, and then was restarted on subsequent response to MP. Interferon toxicity was recorded using a self-report diary. Survival and response duration were calculated using life-table methods, and were adjusted in the analysis for imbalances in baseline prognostic factors.. Four hundred two patients were registered and 176 responders were randomized (85 to interferon and 91 to control). At a median follow-up time of 43 months, the median survival duration was 43 months for interferon and 35 months for control (P = .16), but when adjusted for chance imbalances in baseline prognostic factors (mainly performance status), the median survival duration was 44 months and 33 months for interferon and control, respectively (P = .049). Progression-free survival from randomization to first relapse also favored interferon (unadjusted P < .002; adjusted P < .003). Interferon toxicity caused 58% of patients to reduce their dose, of which 84% were able to return to the initial dose; 14% had to discontinue interferon treatment.. Interferon maintenance therapy improves progression-free and overall survival of patients with multiple myeloma who respond to melphalan and prednisone. Toxicity is substantial and must be weighed by patients against the potential benefits in response duration and survival.

Interferon-alpha for induction and maintenance in multiple myeloma: results of two multicenter randomized trials and summary of other studies.
    Annals of oncology : official journal of the European Society for Medical Oncology, 1995, Volume: 6, Issue:5

    Interferon (IFN) treatment trials in multiple myeloma have yielded discordant results regarding response rates, maintenance duration, and survival times. Further randomized trials and global evaluations of available data are urgently needed for clarification.. 256 patients participated in a randomized trial, 125 on IFN + VMCP, and 131 on VMCP alone. 100 patients were randomized to IFN maintenance (n = 46) or were untreated controls (n = 54). Global evaluations are based on 1,518 patients in induction and 924 in maintenance trials.. The induction trial demonstrated a significantly (p < 0.05) lower rate of progressive disease under IFN + VMCP (10.6%) than under VMCP (22.9%), but this benefit was limited to stage I or II patients. Median progression-free survival was longer in the IFN + VMCP arm (23.2 months vs. 15.8 months); median overall survival did not differ significantly (38.9 vs. 30.2 months). The IFN maintenance treatment trial showed significantly superior results in the IFN arm versus controls (median maintenance duration: 17.8 months and 8.2 months (p < 0.01), survival: 50.6 and 34.4 months (p < 0.05), respectively). Previous IFN treatment increased the benefits of IFN maintenance therapy. Adverse effects of IFN during induction were hematologic toxicity, fever, and infections, requiring dose reductions. Toxic effects of IFN maintenance treatment were mild. Global evaluations of randomized trials showed small but significant benefits of combined IFN induction therapy and significantly prolonged maintenance duration and survival under IFN maintenance.. Presently available data support the use of IFN maintenance treatment because it significantly prolongs maintenance duration and survival. IFN added to induction chemotherapy resulted in minor improvements at the expense of increased toxicity, highlighting the need for better induction regimens.

A comparison of polychemotherapy and melphalan/prednisone for primary remission induction, and interferon-alpha for maintenance treatment, in multiple myeloma. A prospective trial of the German Myeloma Treatment Group.
    European journal of cancer (Oxford, England : 1990), 1995, Volume: 31A, Issue:2

    406 untreated multiple myeloma patients of stage I (n = 54), II (n = 148) and III (n = 204) were enrolled in the trial. 51/54 stage I and 60/148 stage II patients were asymptomatic and followed without treatment until disease progression (progression free survival: 60% after 4 years for stage I versus 50% after 1 year for stage II). Symptomatic patients of stage I (n = 3/54) and II (n = 88/148) presenting with tumour progression, received melphalan 15 mg/m2 intravenously (i.v.) and prednisone 60 mg/m2 oral days 1-4 (MP). Stage II disease remission rate was 59%, and 50% tumour related survival (TRS) was 59 months. Stage III patients were randomised to receive MP or VBAMDex (vincristine/BCNU/doxorubicin/melphalan/dexamethasone) treatment. 43% of MP treated patients responded compared with 64% of the VBAMDex group. 50% TRS was 36 months in both groups without a detectable difference. 117 responders of stage II and III with stable disease were randomised to receive either IFN-alpha (5 x 10(6) IU, subcutaneous (S.C.) 3 times per week) or no maintenance treatment. The relapse rate in both groups was 50% after 13 months. No survival benefit for IFN alpha treated patients was observed (50% TRS: 45 months).

Interferon alfa-2b versus no maintenance therapy during the plateau phase in multiple myeloma: a randomized study. Cooperative Study Group.
    British journal of haematology, 1995, Volume: 89, Issue:3

    This clinical trial was designed to investigate if maintenance therapy with alfa-interferon could prolong the plateau phase in patients with multiple myeloma. In addition, the tolerability of interferon treatment and its effect on survival were evaluated. From September 1987 to September 1989 a total of 314 patients were accrued to a multi-institutional randomized clinical trial. All patients entered into the protocol received standard melphalan-prednisone (MP) induction therapy. Response was noted in 184 (59%) and a plateau phase achieved in 155 (49%). From the latter group, 125 eligible patients were randomized to either interferon alfa-2b or no maintenance. The patients were followed for an average of 51 months (minimum 36 months) from the time of randomization. The plateau phase was significantly prolonged in the group of patients treated with interferon (median 13.9 v 5.7 months from the time of randomization; P < 0.0001). The interferon therapy was tolerated fairly well, moderate granulocytopenia and a chronic fatigue syndrome being the most frequent side-effects (22% v 18% W.H.O. grade 3 toxicity). The median survival from randomization was almost identical in both groups (36 v 35 months). The study shows that interferon maintenance therapy given to multiple myeloma patients who have achieved a response to initial treatment with MP prolongs the plateau phase duration with tolerable toxicity. The clinical value of this finding should be interpreted with caution, because survival was not prolonged. Further studies are required to clarify the role of interferon in the treatment of multiple myeloma.

Monoclonal antibody-purged bone marrow transplantation therapy for multiple myeloma.
    Leukemia & lymphoma, 1995, Volume: 17, Issue:1-2

    This report describes the clinical characteristics, treatment associated toxicity, and follow-up of fifty-eight patients with plasma cell--dyscrasias treated with high dose chemotherapy and total body irradiation (TBI) at a single institution. Following TBI, 36 patients received anti-B cell monoclonal antibody (MoAb)-treated autologous bone marrow, 21 patients received anti-CD6 cell MoAb-treated allogeneic bone marrow to deplete T cells, and one patient received unpurged bone marrow from a syngeneic donor. Evaluation after high dose chemotherapy and bone marrow transplantation (BMT) demonstrated 26 complete responses (CR), 26 partial responses (PR), 2 non-responders, 1 not yet evaluated, and three toxic deaths. Fourteen of 36 patients who underwent autologous BMT are alive free from progression at 18 (range 5 to 68) months post transplant (post-BMT); of these, 11 remain in continuous complete response at 16 (range 5 to 68) months post-BMT. Seven of 21 patients who underwent allogeneic BMT are alive free from progression at 30 (range 4 to 44) months post-BMT; of these, three patients remain in continuous complete response at 43 (range 33 to 45) months post-BMT. These data suggest that high dose chemotherapy with TBI followed by MoAb purged BM can be performed with acceptable toxicity and high tumor response rates.

Maintenance therapy for remission in myeloma with Intron A following high-dose melphalan and either an autologous bone marrow transplantation or peripheral stem cell rescue.
    Stem cells (Dayton, Ohio), 1995, Volume: 13 Suppl 2

    Eighty-four patients with myeloma were randomized to receive maintenance Intron A (Schering-Plough, Suffolk, UK), 3 mega units/m2 s.c. three times weekly or no treatment following induction therapy with cyclophosphomide, vincristine, doxorubicin, methyl prednisolone (C-VAMP), consolidated with high-dose melphalan (HDM) 200 mg/m2 + autologous bone marrow transplantation (ABMT). The patients have been followed up for a median of 52 months. Overall, median progression-free survival (PFS) from HDM was 27 months in the control group and 46 months in the Intron A group (< 0.025). For the 65 patients who achieved complete remission (CR) with HDM, there was a significant prolongation of remission (p = 0.02) for those who received Intron A and 49% of these patients remained in remission four years after high-dose treatment. However, for partial responders (PR) and nonresponders to HDM there was no significant prolongation of PFS. Overall, survival was also significantly better for the Intron A group, with 5 deaths versus 14 deaths in the control group (p = 0.006). Subsequently, 54 consecutive patients received the same HDM followed by rescue with peripheral blood stem cells after induction chemotherapy which included C-VAMP. Intron A was started in 45 of these patients at a median of 62 days which was comparable to the ABMT arm. The overall response rate in these patients was 79.62% (43/54-CR+PR) and the probability of survival at 18 months was 74.2% by the Kaplan Meier method.(ABSTRACT TRUNCATED AT 250 WORDS)

Mobilization of peripheral blood stem cells with chemotherapy and cytokines in multiple myeloma.
    Stem cells (Dayton, Ohio), 1995, Volume: 13 Suppl 2

    In an attempt to offset the impaired hematopoietic progenitors' mobilization and collection which are frequently encountered in multiple myeloma (MM), we have started a pilot study to evaluate the ability of a combination of high-dose melphalan (HDM) and sequential s.c. administration of recombinant human interleukin 3 (rhIL-3) and rh-granulocyte colony-stimulating factor (G-CSF) to mobilize blood cells (BC) in MM patients. Two different schedules for administration were successively tested. Schedule A consisted of IL-3 (5 micrograms/kg/d) from day 7 to day 11 after HDM followed by G-CSF (5 micrograms/kg/d) from day 12 to day 20. Under schedule B, HDM was followed by IL-3 alone at the same dosage from day 1 to day 3, IL-3 and G-CSF (idem) from day 4 to day 7 and G-CSF alone from day 8 until completion of apheresis. Two patients (one previously untreated, one having received prior chemotherapy for one year) underwent schedule A; three patients (one previously untreated, two pretreated) underwent schedule B. The post-HDM aplasia was not shortened in schedule A patients in comparison to what we usually observed following HDM alone (25 days) correlated with a very moderate two- to three-fold CD34+ cell increase. Only one patient was further transplanted with apheresis products: the post-transplant granulocyte recovery was slower than usual (16 days versus 12 days) while platelet count never recovered over 20 x 10(9)/l. In contrast, the post-HDM aplasia was significantly shortened in two of the schedule B patients (3 to 10 days) and was followed by a 25- to 165-fold increase in CD34+ cells.(ABSTRACT TRUNCATED AT 250 WORDS)

Autologous blood progenitor cell transplantation in high-risk multiple myeloma.
    Stem cells (Dayton, Ohio), 1995, Volume: 13 Suppl 2

    The aim of the study was to evaluate the feasibility and the efficacy of high-dose chemoradiotherapy followed by autologous hematopoietic stem cell support with peripheral blood progenitor cells (PBPC) harvested after high-dose cyclophosphamide (HDCYC) treatment in patients with high-risk multiple myeloma (MM). Inclusion criteria were: age less than 65 years and high-risk MM defined as stage II MM, stage III MM, refractory or relapsed MM. The design of the study was: 1) HDCYC +/- hematopoietic growth factors followed by PBPC collection, and 2) high-dose melphalan combined with total body irradiation (or busulfan for previously irradiated patients) followed by PBPC reinfusion (ABPCT). All 60 patients completed the procedure except two who died from infection after HDCYC and another of acute cardiac failure after reinfusion of PBPC. Out of the 60 evaluable patients, three failed to respond while the other 57 achieved either a partial (n = 33) or complete (n = 24) response. Thirty-one patients progressed or relapsed after a median duration of response of 15 months (range: 3-43). The median follow-up for the other 26 responder patients was 24 months (range: 2-66). Twenty-one patients died, 18 of MM (2 after failure, 16 after relapse) and three responders of lung cancer (n = 1) and infection (n = 2). In conclusion, this study shows that this therapeutic approach is feasible and efficient.

Optimal blood stem cell mobilization using 10 micrograms/kg granulocyte colony-stimulating factor (G-CSF) alone for high-dose melphalan intensification in multiple myeloma: an intrapatient controlled study.
    American journal of hematology, 1994, Volume: 47, Issue:2

    A recent randomized multicentric French study has shown that intensification with stem cell rescue improves the response rate and progression-free survival in multiple myeloma. Transplantation with primed peripheral blood stem cells (PBSC) displays a faster hematological recovery, especially for platelets, as compared with a bone marrow stem cell graft. In multiple myeloma, the optimal mobilization method for PBSC is unknown. The present study compares mobilization with cyclophosphamide 4 g/m2 + G-CSF 5 micrograms/kg versus G-CSF 5 micrograms/kg alone versus G-CSF 10 micrograms/kg alone in two cases of multiple myeloma, using an intrapatient controlled evaluation of the amount of CD34-positive cells obtained during each leukapheresis. In both cases, the highest CD34-positive cells yield was obtained with G-CSF at 10 micrograms/kg. Despite the low number of cases, this method, devoid of life-threatening toxicity, might be of greatest interest in multiple myeloma.

Impact of interferon at induction chemotherapy and maintenance treatment for multiple myeloma. Preliminary results of a multicenter study by the Italian non-Hodgkin's Lymphoma Cooperative Study Group (NHLCSG).
    Acta oncologica (Stockholm, Sweden), 1994, Volume: 33, Issue:5

    In 1990 the Italian Non-Hodgkin's Lymphoma Cooperative Study Group (NHLSG) started a multicenter study on the role of interferon (IFN) in multiple myeloma (MM). The schedule of treatment was based on the assumption that melphalan plus prednisone (MP) would be better for good-prognosis patients, whereas poor-prognosis patients would benefit from polychemotherapy. Accordingly, IFN was included randomly for the induction treatment of good-prognosis patients and randomly as maintenance of the response achieved in both groups. Up to now 78 patients of the 124 enrolled have completed the induction treatment and are evaluable for response and response duration. The overall response rate was 59%. Sixty-two percent of good-prognosis patients obtained objective response, 9/14 (64%) with MP and 9/15 (60%) with MP+IFN. Up to now, with a median follow-up of 9 months from the evaluation of response, no difference has been recorded between the maintenance and no maintenance groups on relapse rate, neither in good- nor in poor-prognosis patients.

Autologous bone marrow transplantation in multiple myeloma: a single centre experience of 23 patients.
    Leukemia & lymphoma, 1994, Volume: 15, Issue:3-4

    We report the complications and outcome of high-dose melphalan and TBI combined with ABMT used in the treatment of multiple myeloma at a single centre. Twenty-three patients, aged 65 years or less, who underwent the procedure are reviewed. All had chemosensitive disease. Response to ABMT assessed at 3 months showed 75% of evaluable patients to have further tumour cytoreduction of at least 50%, with 24% of patients who entered ABMT with residual disease eventually achieving CR. There was one toxic death. The overall survival is 60% and the progression-free survival is 49.8% at a median follow-up time of 17 months. Relapse or disease progression has occurred in 27% of patients, of whom half have died. No significant prognostic factors affecting survival were found although those patients with IgG myeloma had a better outcome. Patients transplanted in first plateau appeared to do significantly better if they had been resistant to their first-line chemotherapy but had then responded to further conventional chemotherapy (p = 0.029).

Hematopoietic stem cell autografts in support of myeloablative therapy for multiple myeloma.
    Journal of hematotherapy, 1994,Summer, Volume: 3, Issue:2

    This paper reports the experience of a single investigator team on the use of autografting in support of myeloablative therapy for multiple myeloma. This demonstrates continued progress toward decreased morbidity, and virtual elimination of mortality, as a result of rapid hematopoietic recovery, due to the use of peripheral blood stem cell grafts in newly diagnosed patients receiving several non-cross-resistant induction regimens followed by two autologous transplants, complete remission rates in excess of 50% can be achieved. Prognostic factors have also been identified for event-free and overall survival.

Combination chemotherapy, glucocorticoids, and interferon alfa in the treatment of multiple myeloma: a Southwest Oncology Group study.
    Journal of clinical oncology : official journal of the American Society of Clinical Oncology, 1994, Volume: 12, Issue:11

    Standard therapy for multiple myeloma consists of cytotoxic chemotherapy plus glucocorticoids. Interferon (IFN) alfa maintenance is reported to prolong chemotherapy-induced remissions and survival. This study evaluates induction chemotherapy, glucocorticoids, and interferon maintenance in myeloma.. Five hundred twenty-two previously untreated myeloma patients were randomized to three chemotherapy regimens with differing glucocorticoid intensities. Patients who achieved remission were randomized to receive IFN or observation until relapse. Patients who failed to respond to chemotherapy received IFN alfa plus dexamethasone (DEX).. Five hundred nine patients were eligible for induction chemotherapy. Chemotherapy with higher dose-intensity glucocorticoids yielded higher response rates and improved survival (P = .02 for the three-group comparison; P < .05 for each higher glucocorticoid arm v vincristine, melphalan, cyclophosphamide, and prednisone alternating with vincristine, carmustine [BCNU], doxorubicin, and prednisone [VMCP/VBAP]). One hundred ninety-three patients who achieved remission were randomized to receive IFN alfa 3 MU three times weekly or observation. IFN was not superior to observation for relapse-free (P = .95) or overall survival (P = .39) from start of maintenance. Eighty-eight induction failures received 5 MU of IFN three times weekly plus DEX. Patients who received IFN/DEX had a median survival duration of 48 months from start of IFN/DEX.. Higher-dose glucocorticoids increases frequency of response to chemotherapy and prolong survival in myeloma. IFN maintenance with the dose schedule used in this trial did not prolong relapse-free or overall survival. We cannot exclude a small effect of IFN, as most individual trials do not have sufficient statistical power. Meta-analysis of randomized trials evaluating IFN maintenance in myeloma might be of value. While IFN appeared ineffective, addition of higher-dose glucocorticoids improved outcome in myeloma.

Use of the hypoxic cell sensitizer etanidazole (SR-2508) with intravenous melphalan and prednisone in the treatment of multiple myeloma: a pharmacokinetic study.
    International journal of radiation oncology, biology, physics, 1994, Jun-15, Volume: 29, Issue:3

    A study was undertaken adding the alkylating agent sensitizer etanidazole to intravenous melphalan and oral prednisone for patients with multiple myeloma. This study explored the toxicity profile of these agents when given together and assessed the ability to attain adequate serum levels of etanidazole to permit sensitization to occur.. Etanidazole was administered intravenously in two doses of 3 g/m2 and 5 g/m2 90 min apart immediately prior to the administration of intravenous melphalan and oral prednisone for three consecutive cycles (total dose 24 g/m2). Patients received three additional cycles without etanidazole, allowing a comparison of hematologic toxicity from melphalan with and without etanidazole.. Hematologic toxicity was moderate (Grade 3 or 4), but severity was similar during cycles with and without etanidazole. Only one patient developed a Grade 1 peripheral neuropathy questionably related to etanidazole. Most patients had etanidazole levels of > or = 70 ug/ml for 7 h, a level felt to be necessary for sensitization to occur.. Etanidazole, administered as described, results in adequate serum levels for potential alkylating agent sensitization, without significant toxicity.

Combination chemotherapy with MCNU, vindesine, melphalan, and prednisolone (MCNU-VMP therapy) in induction therapy for multiple myeloma. Japan Myeloma Study Group.
    International journal of hematology, 1994, Volume: 59, Issue:2

    From January 1988 until December 1990, 99 previously untreated patients with multiple myeloma (MM) were enrolled in a randomized prospective study comparing two combination chemotherapies with and without MCNU as induction therapy for MM; 49 patients with vindesine, melphalan and prednisolone (VMP therapy) versus 50 patients with MCNU, vindesine, melphalan and prednisolone (MCNU-VMP therapy). Seventy-two evaluable patients (34 patients in the VMP group, 38 in the MCNU-VMP group) were analyzed. The response rate was slightly higher with MCNU-VMP than with VMP (81.6% vs. 64.7%). In 43 responders (21 patients in the VMP group and 22 in the MCNU-VMP group) who were treated with the same regimen as the induction therapy to maintain remission, the remission duration was significantly longer in patients treated with MCNU-VMP than in those treated with VMP (median > 10.1 vs. 8.0 months, P = 0.018), particularly in patients with PS 3-4. The remission duration in the MCNU-VMP group was also slightly longer in the patients with stage III disease and who were older than 65 years. The median survival time showed no significant difference between the VMP group (20.3 months) and the MCNU-VMP group (> 15 months). Leukopenia, thrombocytopenia and nausea/vomiting were found to be somewhat severe in the MCNU-VMP group. In summary, MCNU-VMP therapy is effective as induction therapy for MM.

High-dose melphalan and autologous bone marrow transplantation as consolidation in previously untreated myeloma.
    Journal of clinical oncology : official journal of the American Society of Clinical Oncology, 1994, Volume: 12, Issue:4

    We report the results of intensive chemotherapy with high-dose melphalan (HDM) following conventional-dose cytoreductive chemotherapy in previously untreated patients with myeloma.. From 1986 to 1991, 53 previously untreated patients with myeloma received HDM 200 mg/m2 plus methylprednisolone 1.5 g daily (MP) for 5 days with autologous bone marrow transplantation (ABMT) after cytoreductive chemotherapy.. At the time of HDM administration, responses to induction therapy were complete remission (CR) in nine patients, partial remission (PR) in 38, and no response (NR) in six. Following HDM, all but one patient responded, with 40 patients achieving a CR (75%). There was one treatment-related death following HDM. The median time to reach a WBC count more than 1,000/microL and platelet count more than 25,000/microL was 19 days (range, 13 to 30) and 24 days (range, 15 to 55), respectively. The median duration of response has not been reached at 20 months, and it is significantly longer for patients in CR than for those in PR (P < .025). Currently, with a median follow-up duration of 31 months (range, 6 to 58), 12 patients are dead and 40 are alive, and the estimated probability of survival at 54 months is 63%. Multivariate analysis found hemoglobin (Hb) more than 10 g/dL (P = .012), and stage A disease (P = .001) at diagnosis to be favorable indicators for survival.. Myeloma patients who are able to receive HDM plus ABMT following conventional chemotherapy achieve a high proportion of CRs, which may be associated with prolonged survival.

Multiple myeloma treated with mitoxantrone in combination with vincristine and prednisolone (NOP regimen) versus melphalan and prednisolone: a phase III study. Nordic Myeloma Study Group (NMSG).
    European journal of haematology, 1993, Volume: 51, Issue:2

    One-hundred-and-fifty-one patients with previously untreated multiple myeloma were allocated to treatment with either NOP regimen (mitoxantrone 16 mg/m2 and vincristine 2 mg day 1 and prednisolone 250 mg day 1-4 and 17-20) or M+P regimen (melphalan 0.25 mg/kg and prednisolone 100-200 mg/day day 1-4). Both regimens were repeated every 4 weeks and were scheduled for 1 year. Seventy-seven patients were treated with NOP and 74 patients with M+P. No major clinical differences were recorded between the groups before treatment. Sixty percent of the patients responded (CR+PR) to NOP versus 64% to M+P (NS). The time to progression was 16 months (95% C.L. 14-51) in the NOP group versus 21 months (95% C.L. 15-27) in the M+P group (NS). The median survival was 14 months (7-21) in the NOP group and 31 months (21-43) in the M+P group (p = 0.02). NOP was significantly more toxic than M+P. Seven patients treated with NOP died due to infection and neutropenia and 1 patient died of cardiac toxicity, in contrast to 1 death due to infection and neutropenia in the M+P group. Gastrointestinal toxicity was acceptable in both groups. In conclusion, NOP was inferior to M+P as primary treatment of multiple myeloma.

Corticosteroid is not beneficial in multiple-drug combination chemotherapy for multiple myeloma. Finnish Leukaemia Group.
    European journal of haematology, 1993, Volume: 51, Issue:2

    In a randomised multicentre trial a combination of methylprednisolone, vincristine, lomustine, cyclophosphamide and melphalan (MOCCA) was compared with the same regimen omitting methylprednisolone after the first course (COLA) in previously untreated patients with multiple myeloma. The MOCCA arm showed a response rate of 72% among 79 patients and the COLA arm a response rate of 60% among 59 patients. This difference was not statistically significant. The median survival time was 56 months in the MOCCA arm and 61 months in the COLA arm. There was a slight increase of early deaths (within the first 6 months) in the MOCCA arm as compared with the COLA arm. We conclude that, in multidrug therapies, the continuation of corticosteroid at conventional dosage beyond the first course does not improve response rate or survival time in multiple myeloma.

Serum thymidine kinase as a prognostic indicator for patients with multiple myeloma: results from the MRC (UK) V trial.
    British journal of haematology, 1993, Volume: 84, Issue:2

    The significance of serum thymidine kinase (STK) as a prognostic indicator for patients with myeloma has been evaluated by determining the pre-treatment level of STK in a retrospective study of 547 patients from the Medical Research Council (MRC) V Myeloma Trial. Overall, STK was a highly significant prognostic factor (Chi 2 = 7.91; P = 0.005). At the time of censor, 23.4% of patients with a presentation STK of < 6 U/l but only 7.9% of the patients with an STK of > 11 U/l were still alive. STK proved to be a highly significant prognostic indicator for the 270 melphalan-treated patients (Chi 2 = 12.37; P = 0.0004) but had no prognostic significance for the 277 ABCM (adriamycin, BCNU, cyclophosphamide and melphalan) treated patients (Chi 2 = 0.29; P = 0.59). When the STK data was stratified for serum B-2-microglobulin (SB2M) it was demonstrated that STK was independent of SB2M and provided additional prognostic information for patients who were treated with melphalan. Thus patients with both a low STK and SB2M had the best prognosis (median survival 1677 d) and those patients with a high STK and SB2M had the worst prognosis (median survival 519 d). STK is a good prognostic marker for patients treated with melphalan but the prognostic significance of STK may disappear with the introduction of new chemotherapy regimens.

A randomized clinical trial comparing melphalan/prednisone with or without interferon alfa-2b in newly diagnosed patients with multiple myeloma: a Cancer and Leukemia Group B study.
    Journal of clinical oncology : official journal of the American Society of Clinical Oncology, 1993, Volume: 11, Issue:1

    This clinical trial was designed to compare the effectiveness of the standard melphalan and prednisone regimen to that of melphalan, prednisone, and interferon in patients with untreated multiple myeloma.. Between October 1985 and March 1988, 278 patients were accrued to a multi-institutional, randomized clinical trial. Responding patients were treated for 2 years before termination of therapy.. After a median follow-up of 23 months, the overall remission rate for the melphalan/prednisone treatment group was 44% compared with 33% for the group receiving melphalan/prednisone/interferon alfa-2b. The durations of response and survival were identical for the two treatment groups. Median survival was 3.17 years on melphalan/prednisone treatment and 3.0 years on melphalan/prednisone/interferon alfa-2b treatment. Both hematologic and nonhematologic toxicities were greater in the melphalan/prednisone/interferon alfa-2b treatment group, but were usually of a mild or moderate degree and did not interfere with the completion of therapy. The frequency of deaths in the two treatment groups attributable to the treatment itself was similar.. This study shows no advantage to the concomitant delivery of interferon alfa-2b with standard melphalan and prednisone as initial treatment for patients with multiple myeloma.

Treatment of multiple myeloma with intensive chemotherapy followed by autologous BMT using marrow purged with 4-hydroperoxycyclophosphamide.
    Bone marrow transplantation, 1993, Volume: 11, Issue:2

    In August 1988 we began a program in which multiple myeloma patients achieving < or = 10% marrow plasma cells and > or = 50% reduction in paraprotein levels after the VAD (vincristine, doxorubicin, dexamethasone) regimen underwent bone marrow harvest, ex vivo marrow purging with 4-hydroperoxycyclophosphamide (4-HC) and marrow cryopreservation. Conditioning with a regimen of high-dose busulfan (total dose 16 mg/kg), cyclophosphamide (120 mg/kg) and melphalan (90 mg/m2) (BU + CY + MEL) followed by autologous BMT was then carried out. Seventeen of the 24 patients who received VAD (71%, 95% confidence interval [CI] 49 to 87%) were eligible for bone marrow harvest. One patient was not harvested because of non-medical reasons; two patients who underwent marrow harvest had gross plasmacytosis present in biopsies performed intraoperatively and did not undergo BMT. Fourteen patients (58%, 95% CI 37 to 78%) received BU + CY + MEL and 4-HC-purged autologous BMT. The median time to recovery of 0.5 x 10(9)/l neutrophils was 19 days (range 14 to 26) while the last platelet transfusion was given on a median of day 32 (range 10 to 46) post-BMT in the evaluable patients. The major non-hematologic toxicity was hepatic; two patients in complete remission died of hepatic veno-occlusive disease. Another patient succumbed to fungal infection despite neutrophil recovery. The remaining 11 patients achieved responses (complete in six and partial in five) associated with a normal performance status.(ABSTRACT TRUNCATED AT 250 WORDS)

Initial versus deferred melphalan-prednisone therapy for asymptomatic multiple myeloma stage I--a randomized study. Myeloma Group of Western Sweden.
    European journal of haematology, 1993, Volume: 50, Issue:2

    From October 1983 until December 1988, 50 patients with asymptomatic multiple myeloma stage I were included in a prospective randomized multi-centre study comparing melphalan-prednisone (MP) therapy started at the time of diagnosis with deferred therapy where MP was started at the time of disease progression. Twenty-five patients were randomized to each group. The median time from diagnosis to start of therapy in the group with deferred therapy was 12 months. The reasons for starting therapy were increasing M-protein in 8 cases, symptomatic bone disease in 9 and anaemia in 5. In 2 cases, disease progression was complicated by vertebral fractures necessitating radiotherapy. Two patients in the group in which MP was started at the time of diagnosis developed acute leukaemia. No differences in response rate, response duration or survival were observed between the treatment groups. We conclude that in asymptomatic myeloma deferral of chemotherapy is feasible in well-informed and well-controlled patients but conveys no advantage in survival. In clinical practice the benefits of treatment deferral are to some extent outweighed by disease progression before start of treatment.

Natural interferon-alpha in combination with melphalan/prednisone versus melphalan/prednisone in the treatment of multiple myeloma stages II and III: a randomized study from the Myeloma Group of Central Sweden.
    Blood, 1993, Mar-15, Volume: 81, Issue:6

    Three hundred thirty-five previously untreated patients with multiple myeloma in clinical stages II and III entered a randomized trial comparing intermittent oral melphalan and prednisone (MP) therapy (n = 171) with MP in combination with natural (leukocyte-derived) alpha-interferon (MP/IFN) (n = 164). The treatment groups were comparable with regard to major prognostic factors. The response frequency was 42% in the MP group and 68% in the MP/IFN group (P < .0001). Eighty-five percent of IgA myelomas and 71% of Bence-Jones myelomas responded to MP/IFN compared with 48% and 27%, respectively, to MP treatment (P = .001). There was no difference in the overall survival between the two treatment groups. However, the survival of 72 patients with IgA or Bence-Jones myeloma randomized to receive MP/IFN was significantly longer (median 32 months) than that of 71 patients treated with MP (median 17 months) (p < .05). No statistically significant difference in response frequency (60% v 46%) or survival was found for patients with IgG myeloma. Hematologic toxicity, WHO grades III and IV, was higher in the MP/IFN group (48%) than in the MP group (33%) (P < .05) during the induction treatment period. Flulike syndrome was observed in 68% of patients receiving MP/IFN. The results show that MP/IFN is a well-tolerated treatment regimen, superior to MP for remission induction, and it improves significantly the overall survival for patients with IgA and Bence-Jones myelomas.

Multiple myeloma: effect of daily dichloromethylene bisphosphonate on skeletal complications.
    Annals of hematology, 1993, Volume: 66, Issue:3

    In 1989, a prospective randomized multicenter study was initiated in order to determine the safety and efficacy of oral clodronate in myeloma patients. The primary objective of this long-term trial is to evaluate whether supportive clodronate is able to prevent or retard the progression of bone disease and reduce the occurrence of characteristic complications: pain, pathologic fractures, and hypercalcemia. We now report first results as an interim analysis, including data obtained from 26 patients (total number of Tübingen patients n = 36) who entered the study at the Medizinische Universitätsklinik Tübingen. Patients were randomized to receive either chemotherapy alone (melphalan 15 mg/m2 i.v. on day 1 and prednisolone 60 mg/m2 orally on days 1-4 every 4 weeks (control group) or in combination with 1600 mg clodronate/day orally as a single dose for a period of at least 1 year. Repeated radiologic examinations in addition to hematologic and biochemical analysis were performed in order to evaluate the skeletal status with respect to lytic bone lesions and osteoporosis and the course of serum M protein and light chain excretion into urine. Clodronate treatment resulted in a significant decrease of serum calcium concentrations and of biochemical indices for bone resorption. No clodronate-related toxicity or hypocalcemia was observed. In patients treated with chemotherapy alone, this effect was less marked and discontinuous. Clodronate-treated patients developed fewer progressive bone lesions (significant for lytic, not for osteoporotic lesions). No hypercalcemic episodes occurred in the clodronate-treated patients, but there were six episodes in the control group. Whereas the number of vertebral fractures was evidently less is clodronate-treated patients, three of those patients suffered from multiple fractures of long bones and ribs. All together, 12 pathologic fractures occurred in five clodronate-treated patients, whereas in the control group 23 pathologic fractures occurred in the same number of patients during the whole observation period. The final analysis of all multicenter included patients should clarify these findings. There was a significant finding that clodronate proved to have an analgesic effect.

Alternating combination VCMP/VBAP chemotherapy versus melphalan/prednisone in the treatment of multiple myeloma: a randomized multicentric study of 487 patients.
    Journal of clinical oncology : official journal of the American Society of Clinical Oncology, 1993, Volume: 11, Issue:6

    To determine whether combination chemotherapy with alternating cycles of vincristine, cyclophosphamide, melphalan, and prednisone (VCMP) and vincristine, carmustine (BCNU), Adriamycin (doxorubicin; Farmitalia, Carlo-Erba Laboratories, Spain), and prednisone (VBAP) is better than the standard melphalan-prednisone (MP) regimen in multiple myeloma (MM).. From January 1985 to December 1989, 28 institutions of the Spanish Cooperative Group for Hematological Malignancies Treatment, Spanish Society of Hematology (PETHEMA) entered 487 eligible patients with symptomatic MM into the study. Patients were randomized to receive either MP or alternating courses of VCMP and VBAP. Logistic regression and the Cox proportional hazards models were used to assess the association between patients' characteristics and response rate and survival, respectively.. Among 449 patients who were assessable for response, the overall response rate to MP was 51.8% (31.5% objective response plus 20.3% partial response) as compared with 62.7% (45.2% objective response plus 17.5% partial response) to VCMP/VBAP (P = .025). Also, a significantly higher proportion of objective responses was observed with combination chemotherapy (45.2% v 31.5%; P = .004). The factors associated with an unfavorable response rate in the overall series were low platelet count, treatment with MP, high creatinine level and immunoglobulin, (IgG) monoclonal (M)-component. No significant differences were found when survival rates of both groups of patients were compared. However, patients with IgA myeloma treated with VCMP/VBAP survived significantly longer than those who received MP (median, 20.2 v 38.4 months; P < .005).. These results indicate that combination chemotherapy improves response rate in MM. However, this does not result in a significantly different survival rate, except for patients with IgA myeloma, who survive significantly longer with combination chemotherapy.

[New protocols for myeloma chemotherapy plus IFN alpha].
    [Rinsho ketsueki] The Japanese journal of clinical hematology, 1993, Volume: 34, Issue:4

    In two consecutive studies of a pilot study and a multicenter trial 16 patients and 61 patients, respectively, with multiple myeloma were treated with the combination chemotherapy (CMVM regimen; the same intermittent high dose dexamethasone as in VAD regimen, MCNU bolus injection of 1.2mg/m2 on day 1, melphalan 12mg/day on days 1-6) plus IFN alpha (HLBI 300MU every day or two) to assess the efficacy and the toxicity of this protocol. Both studies were achieved in the same regimen except for initial 12 days administration of IFN alpha in the multicenter trial. The treatment was repeated 3 times every 6-8 weeks. Complete remission (CR) in which serum and urine M protein disappeared and myeloma cells in bone marrow were eradicated was obtained in 6 in 16 patients (37.5%) in the pilot study and 16 in 61 patients (26.2%) in the multicenter trial. CR plus PR was 68.8% and 68.9% in two studies. The achievement of CR in such high proportion of patients may exhibit a significant advance in the myeloma therapy.

Myeloma--results of treatment 1986-1990.
    The Ulster medical journal, 1993, Volume: 62, Issue:1

    Sixty-nine patients with multiple myeloma diagnosed during a five year period at the Belfast City Hospital were followed until death or for a minimum of one year in a retrospective study of survival. Although the patients were unselected, survival data was found to be similar to results from trials in which patient selection had occurred. Overall median survival was thirty-two months. Median survival fell with advancing disease and was 47, 27 and 18 months for Durie-Salmon stages I, II and III respectively. Those patients presenting with a platelet count of < 100 x 10(9)/1 had a median survival of eight months in contrast to those with a platelet count > 100 x 10(9)/1 whose median survival was 36 months. Patients presenting in renal failure had a shorter median survival of 28 months compared to 46 months for those with normal renal function.

Combined chemotherapy with ABCM versus melphalan for treatment of myelomatosis. The Medical Research Council Working Party for Leukaemia in Adults.
    Lancet (London, England), 1992, Jan-25, Volume: 339, Issue:8787

    Both melphalan and cyclophosphamide increase life expectancy in patients with myelomatosis, but few large randomised studies have compared combination chemotherapy regimens with these single agents. In the Vth MRC myelomatosis trial, the survival of 314 patients randomised to receive ABCM (adriamycin, BCNU, cyclophosphamide, and melphalan) as first-line treatment was significantly longer than that of 316 patients given intermittent melphalan (M7) (p = 0.0003). The 75%, median, and 25% survivals were 7, 24, and 42 months, respectively, with M7 and 10, 32, and 56 months, respectively, with ABCM. Stable disease with few symptoms (plateau) was achieved by 61% of patients given ABCM and 49% of those given M7 (p = 0.004). Myelotoxicity was comparable between regimens. Cross-trial analysis suggests that M7 is comparable to melphalan and prednisone or melphalan, prednisone, and vincristine; that the efficacy of ABCM in the Vth trial and VIth MRC trials is comparable; and that ABCM gave better survival than intermittent melphalan regimens in the prognostic groups analysed. The results indicate that ABCM is an acceptable regimen that is more effective than melphalan, with or without prednisone, for first-line treatment of myelomatosis.

Modified adriamycin-vincristine-dexamethasone (m-VAD) in primary refractory and relapsed plasma cell myeloma: an NCI (Canada) pilot study. The National Cancer Institute of Canada Clinical Trials Group.
    British journal of haematology, 1992, Volume: 82, Issue:3

    The purpose of this single arm phase II study was to test a modified version of the three drug combination vincristine, adriamycin and dexamethasone (m-VAD), in which intravenous vincristine (0.4 mg/d) and adriamycin (9 mg/m2 per day) infusions are administered for only 2 h on days 1-4 of each 28 d cycle, in patients with refractory multiple myeloma. In addition, only two 4 d courses of dexamethasone 40 mg/d was given during each cycle. The entry criteria for 44 patients included plasma cell myeloma and a measurable monoclonal peak, either refractory to initial treatment with melphalan and prednisone, or resistant to melphalan and prednisone after initially responding (resistant relapsed disease, 27 patients). Patients treated previously with chemotherapy other than melphalan and prednisone were excluded. There were no complete responses. Of the 41 evaluable patients who completed at least one course of therapy 11 had a partial response (27%, 95% C.I. 14-40%). The response rates were 19% for primary refractory disease patients, and 32% for those with resistant relapsed disease. The median duration of response was 4 months. The median survival for all 44 patients was 7.6 months (5.5 months for primary refractory patients, and 10 months for relapsed resistant disease patients). Episodes of documented bacterial infection occurred in 12 patients, and 10 patients had minor viral infection. The dexamethasone dose was reduced in 12 patients. The median neutrophil nadir was 1.2 x 10(9)/l, and median platelet nadir was 147 x 10(9)/l. Five deaths were judged as treatment related and occurred during marrow cytopenia. The results of this modified form of VAD are inferior to that reported previously for 4 d continuous infusions of vincristine and doxorubicin. This could be related to either patient selection factors, or to a reduction of the efficacy of the drug combination produced by either the shortened intravenous infusions and/or omission of one 4 d course of dexamethasone.

Intensive combined therapy for previously untreated aggressive myeloma.
    Blood, 1992, Mar-01, Volume: 79, Issue:5

    A trial was initiated to determine the feasibility and efficacy of a three-phase treatment including: (1) induction chemotherapy (IC); (2) high-dose melphalan with total body irradiation supported by unpurged autologous bone marrow transplantation (ABMT); and (3) interferon (IFN) alpha maintenance treatment, in previously untreated aggressive myeloma. Thirty-five consecutive patients, ages under 65 years, were enrolled. Initial induction therapy was randomized between the VAD regimen (vincristine, doxorubicin, dexamethasone) or the VMCP regimen (vincristine, melphalan, cyclophosphamide, prednisone) that were found to give similar results as IC. Thirty-one of 35 (89%) patients, with good performance status and normal renal function after IC, received ABMT. IFN alpha was started soon after ABMT and was well tolerated. Fifteen of 35 (43%) patients achieved complete response (CR) and 14 of 35 (40%) achieved partial response (PR). Low pretreatment beta 2 microglobulin was the only predictive factor for accomplishing CR. The duration of response was significantly affected by the magnitude of response. The 33-month, post-ABMT probability of progression-free survival was 85% for patients in CR versus 24% for patients in PR. The 42-month, post-diagnosis probability of survival was 81%. This overall strategy may represent an advance in the management of multiple myeloma. Furthermore, the high rate and long duration of CR that we observed in patients with low beta 2 microglobulin suggest that such patients may preferentially benefit from this strategy.

VAD or VMBCP in severe multiple myeloma. The Groupe d'Etudes et de Recherche sur le Myélome (GERM).
    British journal of haematology, 1992, Volume: 80, Issue:2

    A randomized trial has been performed in which 91 patients with stage III myeloma and additional severe criteria were randomly allocated to either VAD or VMBCP. No significant difference was noted between these two groups using the following criteria: response rate (VMBCP: 54%; VAD: 39%), impact on symptoms, median survival (VMBCP: 14 months, VAD: 17 months). However, toxic effects and refusal to pursue treatment were more frequent with VAD than with VMBCP (12 v 6). Therefore, in this trial, VMBCP appears to be more useful than VAD.

    80 patients with resistant or relapsing multiple myeloma received a combination of vincristine, cyclophosphamide, lomustine, melphalan and methylprednisolone (MOCCA) as a second-line chemotherapy. 27 of them were resistant to primary chemotherapy with alkylating agents, and 53 had relapsed after initially responding to these drugs. An objective response was achieved in 39 patients (49%): in 14 patients who were primarily resistant (52%) and in 25 patients who had a relapse (47%). Of 41 patients relapsing during maintenance chemotherapy 14 (34%) responded, while 11 of 12 patients (92%) treated for a relapse off-therapy responded. The median duration of response was 22 months. Severe complications, in most cases infections, occurred in 30% of patients, and were fatal in 9% of the cases. According to our experience the five-drug combination MOCCA is an effective second-line chemotherapy for myeloma patients primarily resistant to or relapsing after therapy with single alkylating agents.

Phase I-II trial of high-dose melphalan in previously untreated stage III multiple myeloma: Cancer and Leukemia Group B study 8512.
    Cancer investigation, 1992, Volume: 10, Issue:1

    To study the efficiency of high-dose melphalan in previously untreated patients with advanced myeloma, we performed a Phase I-II trial. Twenty-eight patients were treated at dose level of 60-140 mg/m2. Each patient was first treated with a priming dose of cyclophosphamide (300 mg) followed by high-dose melphalen 1 week later. One course of therapy was given. Patients were then followed without further therapy until relapse. Clinical and laboratory features of the 28 patients in this study included: median age 63, performance status 0-2, hypercalcemia 21%, bone pain 82%, paraprotein types: IgG 76%, Iga 20%, and paraproteinuria 71%. Because none of the patients achieved complete remission (CR) at 60 mg/m2, despite life-threatening toxicity in all patients, the dose level was rapidly increased to 140 mg/m2, a dose previously reported to induce a high percentage of CR. At this dose, CR was achieved in only 1 of 11 patients (9%). This patient had multiple plasmacytomas without generalized bone marrow involvement. One additional patient at 100 mg/m2 achieved CR. Of the whole group, 12 achieved PR. Durations of remissions were generally short: CR 6.3 and 18+ months and PR 2.3-18 month, median 6.9 months. Life-threatening myelosuppression was universal with prolonged pancytopenia. Treatment-related deaths from sepsis were observed in 29% of patients. The median survival of the entire group was 15.6 months. Older patients in this trial did not tolerate high-dose melphalen therapy well; this resulted in a high proportion of toxic deaths and poor overall survival.

Intermediate dose of intravenous melphalan in advanced multiple myeloma.
    Oncology, 1991, Volume: 48, Issue:5

    Eighteen patients with advanced multiple myeloma resistant to VAD chemotherapy (vincristine, Adriamycin, dexamethasone) were treated with intravenous melphalan in a single-pulse dose of 50-70 mg/m2. Objective response (greater than or equal to 50% reduction of the monoclonal protein) was observed in 9 patients. The median duration of remission in the responding patients was 6 months and the median survival 11.5 months. The main toxicity noted was bone marrow suppression. We conclude that intermediate doses of intravenous melphalan are a useful therapeutic modality in refractory or relapsing myeloma patients.

Interferon alfa-2b with VMCP compared to VMCP alone for induction and interferon alfa-2b compared to controls for remission maintenance in multiple myeloma: interim results.
    European journal of cancer (Oxford, England : 1990), 1991, Volume: 27 Suppl 4

    The present trial was designed to evaluate whether interferon (IFN) combined with standard induction chemotherapy and/or interferon remission maintenance treatment improve treatment results in patients with multiple myeloma. Up to now 89 patients have received IFN plus vincristine/melphalan/cyclophosphamide/prednisolone (VMCP) as induction therapy, and 86 conventional VMCP. The proportion of patients with progressive disease was significantly lower (P less than 0.005) under IFN + VMCP as compared to the VMCP treatment group. Survival times were significantly longer (P less than 0.02) after IFN + VMCP induction therapy than after VMCP alone. In the second phase of this investigation, 33 progression-free myeloma patients were assigned to receive IFN as maintenance therapy, and 41 patients served as untreated controls. Patients maintained with IFN showed a tendency towards increased progression-free survival. Haematological side effects were observed significantly more often in patients receiving IFN, with more severe haematological toxicity in patients on the combined IFN + VMCP regimen and an increased number of patients with mild haematological toxicity in the group maintained with IFN. Other side effects, such as fever and fatigue, remained within tolerable limits. In conclusion, the preliminary results of this current clinical trial indicate significant advantages of combined IFN + VMCP induction treatment in terms of reduced disease progression and prolonged survival and possible benefits of IFN maintenance therapy in patients with multiple myeloma.

Interferon therapy during the plateau phase of multiple myeloma: an update of the Swedish study.
    European journal of cancer (Oxford, England : 1990), 1991, Volume: 27 Suppl 4

    A multicentre clinical trial was carried out in order to evaluate the effect of interferon (IFN) in patients with multiple myeloma. Patients (n = 120) who had shown response to conventional intermittent melphalan-prednisone induction therapy, and achieved a plateau phase, were randomized at that point to receive either interferon alfa-2b in a dose of 5 million units (MU) three times per week or no therapy. This report presents the results of an interim analysis, performed when the patients had been followed for a median of 20 months. The duration of the plateau phase was significantly longer in the IFN arm (59 weeks), compared to the no therapy arm (26 weeks). A total of 34 deaths have occurred, 13 in the IFN arm and 21 in the no therapy arm. In spite of the high median age of the patients studied (70 years), most patients were able to tolerate a full or only slightly reduced IFN dose.

[Therapeutic plasmapheresis in patients with multiple myeloma].
    Acta haematologica Polonica, 1991, Volume: 22, Issue:1

    The effectiveness of therapeutic plasmaphereses with antineoplastic chemotherapy was evaluated in 25 cases of plasmocytic myeloma in stage III of progression of the proliferative process. The indication to plasmapheresis was hypergelification of serum with clinical symptoms of central nervous system disturbances, renal failure in various stages of progression, intensification of coronary symptoms, bleeding tendency. Good effects with reduced level of total protein and monoclonal protein in serum by 30-80% with regression of clinical symptoms caused by serum hypergelification were obtained in 11 cases. In the remaining patients clinical improvement of varying degree was noted when the level of total and monoclonal protein in the serum fell by 10-29%.

[Chemotherapy and immunomodulating treatment of patients with multiple myeloma].
    Acta haematologica Polonica, 1991, Volume: 22, Issue:1

    Prospective studies were carried out on the effectiveness of various treatment methods in 208 patients with plasmocytic myeloma. In 102 patients induction therapy was based exclusively on melphalan, in 106 cases polychemotherapy was used including vincristine, melphalan, carmustine, cyclophosphamide and prednisone. The differences in the per cent of patients with good response to treatment and in the survival time after treatment beginning were statistically not significant between these groups which suggests that polychemotherapy begun from the diagnosis of the disease is justified in patients with large mass of the neoplasm and poor prognostic factors. In 45 patients chemotherapy was supported by administration of immunomodulatory agents, including calf thymus extract in 25 cases, levamisole in 18 and interferon in 2. It was observed that maintenance of remission with chemotherapy and with immunomodulatory agents calf thymus extract or levamisole prolonged the survival of the patients. In cases of leucopenia the use of calf thymus extract facilitated chemotherapy by stimulation of myelopoiesis.

Second and third responses to the same induction regimen in relapsing patients with multiple myeloma.
    Cancer, 1991, Sep-01, Volume: 68, Issue:5

    From September 1975 to December 1986, 115 consecutive previously untreated patients with multiple myeloma (MM) were treated with combination chemotherapy consisting of BCNU, cyclophosphamide, melphalan, vincristine, and prednisone (M-2). No patients were excluded or lost during follow-up. Forty-three percent of the patients were Stage I plus II, and 57% were Stage III. Thirty-eight patients (33%) had blood urea nitrogen greater than or equal to 40 mg/dl (substage B). Reaching an objective response treatment was stopped, generally after 1 year, and restarted at relapse. After induction therapy, 94 patients (82%) responded and had a median duration of response (MDR) of 22 months. After first relapse, 26 of 38 patients (69%) responded again to the same regimen and had an MDR of 11 months. This response rate and MDR are significantly lower than the ones achieved in induction chemotherapy. After second relapse, 7 of 16 patients (44%) again responded with an MDR of 3.5 months. The median survival time (MST) was 50.5 months for all patients. The most relevant side effect was leukopenia. No case of secondary leukemia was noticed. The authors conclude that patients with MM can be treated safely without maintenance therapy after reaching remission because a high response rate can be obtained in first and even second relapse. The planned treatment pause at remission does not adversely affect the survival time. Secondary leukemia is infrequent after this policy. Quality of life improves during the treatment pause.

Treatment of multiple myeloma with interferon alpha: the Scandinavian experience.
    British journal of haematology, 1991, Volume: 79 Suppl 1

    IFN alpha is a biologic therapeutic agent with documented antitumoral effect in multiple myeloma. 15% of previously untreated myeloma patients achieve a clinical response to IFN alpha alone with a possible dose-response relationship. A particularly good effect is noted in IgA myelomas treated with natural IFN alpha. A randomized study was started in April 1986 comparing melphalan/prednisone (MP) therapy with MP plus natural IFN alpha (MP/IFN) in untreated patients with multiple myeloma stages II and III. 220 patients had entered the study by autumn 1989. An interim report is given here. The response frequency was 48% in the MP group and 66% in the MP/IFN group (P less than 0.02). Stage II patients responded better to MP/IFN (76%) than to MP alone (48%) (P less than 0.01). No significant difference was noted for stage III patients. 91% of all IgA myelomas responded to MP/IFN and 52% to MP (P less than 0.01). The difference in response frequency of IgG and BJ myelomas between the two treatment groups was not statistically significant. The observation period is still too short to draw firm conclusions on survival. However, a statistically significant longer response duration time and survival from response (P less than 0.01) was noted for stage II patients.

alpha-Interferon for remission maintenance: preliminary report on the Southwest Oncology Group Study.
    Seminars in oncology, 1991, Volume: 18, Issue:5 Suppl 7

    This preliminary report focuses on the therapeutic role of interferon in a large randomized trial evaluating combination chemotherapy induction and interferon maintenance, as compared with no maintenance therapy, in patients with newly diagnosed multiple myeloma. The trial also included an evaluation of the combination of interferon and dexamethasone therapy for patients who failed to respond to induction chemotherapy or who had achieved only a partial remission. Case accrual is completed for remission induction with 505 eligible patients registered on study, but is still open for additional maintenance registrations. As of January 1991, 161 patients have been randomized to interferon versus observation, but the therapeutic results of this aspect of the study remain coded. Toxicity of interferon maintenance was generally of a mild to moderate degree, and less severe than that of the interferon/dexamethasone combination, which was due to the addition of steroid side effects. Among 41 patients who failed to achieve remission with chemotherapy, 13 (32%) achieved at least a partial remission with interferon/dexamethasone, and only five others (12%) have had progressive disease. Of 12 partial responders on induction chemotherapy, five (42%) achieved remission (75% tumor regression) with interferon/dexamethasone. To date, more than 65% of patients receiving interferon/dexamethasone remain alive, suggesting that this regimen will be useful for patients who fail to achieve remission with induction chemotherapy.

Interferon therapy during the plateau phase of multiple myeloma: an update of a Swedish multicenter study.
    Seminars in oncology, 1991, Volume: 18, Issue:5 Suppl 7

    Over the course of a 2-year period (September 1987 to September 1989) a total of 432 patients with multiple myeloma were registered in a study comprising 39 Swedish and one Italian clinics. Six of these were university hospitals, the others were county (community) hospitals. A total of 308 patients fulfilled the eligibility criteria of the protocol, and were started on traditional intermittent melphalan-prednisone therapy. Response, defined as a reduction in the concentration of the M-component in serum or urine, was observed in 58% of patients, and a clearly defined plateau phase was noted in 38% of the cases. Of the patients who achieved a plateau phase, 120 individuals (with a median age of 71 years) were at this point randomized between no further therapy and continuous interferon-alfa-2b at a dose of 5 x 10(6) IU subcutaneously three times per week. At relapse the interferon therapy was discontinued, and melphalan-prednisone restarted. Only preliminary data and interim results are at this point available. The final evaluation of the study will be performed after June 1, 1991. The treatment arms are comparable with regard to age, stage according to Durie-Salmon, renal function, immunoglobulin class, and type of response to the cytostatic therapy (rapid versus slow). A median number of six courses of melphalan-prednisone were administered before randomization. For those patients in whom pretreatment serum beta-2-microglobulin was analyzed, no difference in the median values between the treatment arms was found. The median observation time from randomization is 20 months. At the time of this analysis, 85 had relapsed: 33 of 59 (56%) in the interferon arm, and 52 of 61 (85%) in the no therapy arm. An interim analysis of the duration of the plateau phase (from the time of randomization) was performed in October 1990, showing a highly significant difference between the two treatment arms (P less than .001). The median duration of plateau was 59 weeks in the interferon arm, and 26 weeks in the no therapy arm. To date there have been 34 deaths, 13 in the interferon arm and 21 in the no therapy arm. All patients in the no therapy arm died from multiple myeloma (n = 19), or from another cause, but with the myeloma in an uncontrolled, progressive state (n = 2). In the interferon arm, only 10 patients died from progressive myeloma, and four of these either did not start interferon therapy at all (n = 1), or discontinued therapy early (n = 3).(ABSTRACT TRUNCATED

Multiple myeloma: VMCP/VBAP alternating combination chemotherapy is not superior to melphalan and prednisone even in high-risk patients.
    Journal of clinical oncology : official journal of the American Society of Clinical Oncology, 1991, Volume: 9, Issue:3

    The efficacy of alternating vincristine, melphalan (M), cyclophosphamide, prednisone/vincristine, carmustine, doxorubicin, and prednisone (VMCP/VBAP) polychemotherapy was compared with the M and prednisone (MP) regimen as induction treatment in multiple myeloma (MM). Three hundred four MM patients entered this study between March 1983 and July 1986; the analysis was performed in December 1989. The treatment groups did not show significant differences with respect to major prognostic factors. Median overall survival was 33.8 months. In the VMCP/VBAP and MP arms, after 12 induction chemotherapy cycles, 59.0% and 47.3% (P less than .068) of the patients achieved an M component reduction greater than 50%. No significant difference was observed in the two treatment arms in terms of remission duration (21.3 v 19.6 months, P less than .66) and survival (31.6 v 37.0 months, P less than .28). Patients younger than 65 years did not show any advantage from the alternating polychemotherapy. At diagnosis, the plasma cell labeling index (LI) and serum beta-2 microglobulin (beta 2-m) were evaluated in 173 and 183 patients, respectively. A significantly reduced survival was observed for patients with LI greater than or equal to 2% (16.4 months) or beta 2-m greater than or equal to 6 mg/L (20.4 months). Even in these poor-risk subgroups, VMCP/VBAP was not superior to MP.

No correlation between response and survival in patients with multiple myeloma treated with vincristine, melphalan, cyclophosphamide, and prednisone.
    Cancer, 1991, Jul-01, Volume: 68, Issue:1

    A vincristine, melphalan, cyclophosphamide, and prednisone (VMCP) multi-drug regimen was used in 85 previously untreated patients with multiple myeloma (MM) (symptomatic Durie Stages II and III) until they became refractory. The prognostic significance of various pretreatment characteristics was evaluated in terms of therapeutic response (according to Southwest Oncology Group [SWOG] and Chronic Leukemia-Myeloma Task Force [TF] criteria) and survival. Therapeutic responses, obtained in 31.2% (SWOG) and 68.7% (TF) of patients, had a significant inverse correlation with myeloma cell mass, serum calcium, and bone status. Median survival time of Stage II and Stage III patients was 39 and 34 months, respectively. Serum B2 microglobulin greater than or equal to 6 micrograms/ml was the only variable correlating unfavorably with survival duration after multi-variate analysis (increased risk = 2.79), although therapeutic response as a time-dependent variable had no effect on survival. These data suggest no correlation between response and survival, partially because of inadequate response assessment criteria and partially because no existing treatment is curative (although current therapeutic approaches may prevent death from complications).

    277 untreated multiple myeloma patients of stage 1 (n = 33), II (n = 106) and III (n = 138) entered the study. Patients of stage II presenting a progressive tumor (n = 64) initially or during observation (n = 14) were treated with MivP (remissions: 61%). 138 patients of stage III were randomized to receive MivP or VBAMDex treatment. 51% of MivP treated patients responded versus 70% of the VBAMDex group. 71 responders of stage II and III with stable disease were randomized on Ifn-alpha maintenance versus no maintenance treatment. The relapse rate in both groups was 50% after 7 months. 75% survival was greater than 36 months in stage II and 11 months in stage III patients.

Multi-drug combination therapy with vincristine-melphalan-cyclophosphamide-prednisolone was more effective than cyclophosphamide-prednisolone in stage III myeloma. The Nagoya Myeloma Cooperative Study Group.
    Japanese journal of cancer research : Gann, 1990, Volume: 81, Issue:12

    A cooperative randomized clinical trial to compare the effectiveness of multi-drug combination chemotherapy (VMCP), vincristine-melphalan-cyclophosphamide-prednisolone) with CP (cyclophosphamide-prednisolone) for the treatment of multiple myeloma was performed. When the whole group of patients was evaluated, the choice of chemotherapy (VMCP or CP) was not a significant prognostic factor associated with response or survival by uni- or multivariate analysis, and the difference between the survival curves of the treatment groups was only marginally significant. However, when the analysis was confined to stage III patients, the choice of chemotherapy became a significant prognostic factor associated with both response rate and survival, and the statistical difference between survival curves was significant. Taking the disease characteristics of multiple myeloma into consideration, the better result obtained with multi-drug combination chemotherapy in the treatment of stage III patients is consistent with other studies supporting the superiority of multi-drug combination chemotherapy for patients with overt systemic disease.

Chemotherapy is superior to sequential hemibody irradiation for remission consolidation in multiple myeloma: a Southwest Oncology Group study.
    Journal of clinical oncology : official journal of the American Society of Clinical Oncology, 1990, Volume: 8, Issue:9

    Six hundred fourteen previously untreated patients with multiple myeloma were evaluated on this phase III Southwest Oncology Group (SWOG) trial. For remission induction, two noncross-resistant drug combinations (vincristine, melphalan, cyclophosphamide, and prednisone [VMCP] and vincristine, carmustine [BCNU], Adriamycin [doxorubicin; Adria Laboratories, Columbus, OH], and prednisone [VBAP]) were administered with either a direct alternating or a syncopated schedule. Pretreatment serum beta-2 microglobulin (beta 2M) was the single most important prognostic factor for survival (P less than .0001). There was no difference in toxicity, response, or survival by induction chemotherapy schedule (P greater than .7). For consolidation, 180 eligible and responsive patients were randomized to receive either an additional year of VMCP or sequential hemibody radiation (HBI) with vincristine and prednisone (VP) administered between the two HBI courses. Relapse-free survival (26 months) and overall survival (median, 36 months) were better with VMCP than with HBI (median, 20 months and 28 months; P = .04 and .018, respectively). HBI was also evaluated on a nonrandomized basis in 66 patients who achieved either a partial response (PR) or who were nonresponders to induction therapy. While HBI converted 24% of the PR patients to remission status, this effect was only seen in 5% of nonresponding patients. The survival of responsive and nonresponding patients receiving HBI was similar. All HBI groups had an inferior outcome to those receiving VMCP consolidation. Myelosuppression was also significantly worse after HBI. Survival from the time of relapse did not differ between patients randomized to receive VMCP or HBI. Thus HBI induced less durable remissions, but did not render patients less amenable to postrelapse chemotherapy. Our findings do not support the use of HBI in either chemotherapy responsive or nonresponding patients with multiple myeloma.

Initial treatment in multiple myeloma: no advantage of multidrug chemotherapy over melphalan-prednisone. The Myeloma Group of Western Sweden.
    British journal of haematology, 1990, Volume: 74, Issue:2

    From October 1983 until December 1986, 164 patients with multiple myeloma stage II-III were included in a prospective randomized multi-centre study comparing melphalan-prednisone (MP) with multidrug chemotherapy (MDC). The patients comprised 77% of all newly diagnosed myeloma stage II-III cases reported from 18 hospitals covering the entire Health Care Region of Western Sweden (1.5 million inhabitants). Patients randomized to MP (29 stage II and 55 stage III patients) were given oral melphalan and prednisone every 6 weeks. For patients randomized to MDC, stage II patients (n = 25) were given VMCP every 4 weeks and stage III patients (n = 53) VBAP and VMCP alternately every 4 weeks. For stage II patients, the response rate for MP compared to VMCP was 69 versus 56% and the median survival 46 versus 33 months. For stage III the response rate for MP compared to VBAP/VMCP was 58 versus 57% and the median survival 26 versus 24 months. No statistically significant differences were seen. The time to response and remission duration were also similar in both treatment arms. The dose intensity index (cumulative given/planned dose of myelosuppressive drugs) was greater than or equal to 0.8 in 89% of the MP patients and 81% of the MDC patients. Patients with index values less than 0.8 had the same response rate as patients with index greater than or equal to 0.8. This study has not demonstrated any advantage of MDC over traditional MP in multiple myeloma stage II-III.

    136 untreated multiple myeloma patients of stage II and III were collected in the study. 37/51 stage II patients had progressive disease and were treated with melphalan and prednisone (MP). 85 patients were of stage III and randomized into MP and vincristine, BCNU, adriamycin, melphalan and dexamethasone (VBAMDex) treatment groups. 55% of MP treated patients responded versus 75% of the VBAMDex group. Since the study has been activated only 16 months ago, no difference in survival could be observed.

A randomized multicentric study comparing alternating combination chemotherapy (VCMP/VBAP) and melphalan-prednisone in multiple myeloma.
    Blut, 1990, Volume: 60, Issue:6

    Between January 1985 and December 1988, 386 patients with multiple myeloma were randomized to receive either MP or combination chemotherapy based on alternating cycles of VCMP and VBAP. The major prognostic parameters did not differ significantly between both treatment groups. A significantly higher proportion of objective responses was observed with combination chemotherapy as compared to MP (47.8 vs 32.2, P = 0.01). The median survival for all patients was 33.5 months. So far no significant differences were found when comparing the survival curves from both groups of patients. However, the median survival of MP-treated patients is 26.8 months, whereas the median survival of patients receiving VCMP/VBAP has not yet been reached. The definitive analysis must await the evaluation of all patients entered into the study and a longer follow-up time.

    Acta oncologica (Stockholm, Sweden), 1990, Volume: 29, Issue:6

    Eighty-one previously untreated patients with multiple myeloma stage II entered a randomized trial comparing oral melphalan (0.25 mg/kg/day; n = 40) with intravenous melphalan (0.125 mg/kg/day; n = 41) in combination with oral prednisone (2 mg/kg/day). The courses were given for 4 days and repeated every sixth week. The treatment groups were well comparable with regard to major prognostic factors. There was no statistically significant difference in the response rates, the response duration times and the survival times. No significant difference in nonhematological and hematological toxicity was noted. Since intravenous administration of melphalan did not result in a substantial increase in response rate or survival, this study supports the use of oral melphalan/prednisone as first-line therapy for patients with multiple myeloma.

Alpha-2a-interferon/melphalan/prednisone versus melphalan/prednisone in previously untreated patients with multiple myeloma.
    British journal of haematology, 1990, Volume: 76, Issue:3

    Alpha-2a-interferon (IFN) has demonstrable activity in advance and refractory multiple myeloma (MM), because of the in vitro synergism between IFNs and cytotoxic agents we report the preliminary results of a therapeutic trial of 50 patients with MM. Twenty-eight patients were randomized to receive melphalan plus prednisone (MP) and 22 were randomized to receive IFN plus MP (IFN-MP). Criteria for response, progression and relapse were those of the Southwestern Oncology Group. 95% of the patients receiving IFN-MP responded to therapy as opposed to 68% of the patients receiving MP (P less than 0.05). Response was independent of M-component immunoglobulin class but in stage III it was higher in the IFN-MP group than in the MP group (P less than 0.05). The combination IFN-MP was well tolerated without unusual or unexpected toxic effects. The response duration time was longer in the IFN-MP group than in the MP group (P less than 0.025). The median survival was 80 weeks in the MP group and in the IFN-MP group the 93% of patients were still alive after 90 weeks (P less than 0.025). Our results show that the use of the IFN as an adjuvant to MP improves the percentage of responders, the response duration time and the median survival of untreated patients with MM.

Oral melphalan pharmacokinetics: influence of interferon-induced fever.
    Clinical pharmacology and therapeutics, 1990, Volume: 47, Issue:1

    The influence of interferon-induced fever on oral melphalan pharmacokinetics has been studied in 10 myeloma patients in a randomized crossover design. The melphalan dose (0.25 mg/kg) was given alone and 5 hours after the administration of human interferon alpha (7 x 10(6) IU/m2), respectively. The plasma concentration of melphalan was determined by liquid chromatography with fluorometric detection after derivatization of melphalan with N-acetylcysteine. The area under the plasma concentration-time curve (AUC) was significantly lower (p = 0.02) when melphalan was given with interferon. There was a significant negative correlation (p = 0.008) between body temperature and dose normalized AUC, whereas no effect was noticed on the maximum plasma concentration (Cmax) and on the time to obtain Cmax. The rate of elimination showed a tendency (p = 0.06) to increase with increasing body temperature. It is suggested that the cytotoxicity of the drug is most probably enhanced because of the higher alkylating activity of the compound at elevated body temperatures.

Treatment of multiple myeloma in old patients. Finnish Leukaemia Group.
    European journal of haematology, 1989, Volume: 43, Issue:4

    Patients aged 70 yr or older with multiple myeloma were treated, when suitable, according to concurrent trial protocols for younger patients, with the exception that the cytostatic regimen was not allocated at random. Intermittent melphalan and prednisone (MP) was given as the primary treatment to 42 patients and 5-drug combination MOCCA to 68 patients. The groups were comparable with each other, and the distribution of the clinical stages of the patients was similar to the younger patients in concurrent trials. An at least 50% response was achieved in 33% (SE 7.3) with MP and in 75% (SE 5.3) with MOCCA. The median survival times were 39 and 32 months, the relative age-adjusted survival times 45 and 41 months, respectively. Advanced age as such is thus no contraindication for active treatment of myeloma, and in suitable patients the results compare well with those achieved in younger patients.

VMCP chemotherapy with or without interferon-alpha-2 in newly diagnosed patients with multiple myeloma.
    Onkologie, 1989, Volume: 12, Issue:1

    Fifty-two previously untreated patients with multiple myeloma were randomized to either a combination of recombinant interferon (rIFN) alpha-2 and chemotherapy or chemotherapy alone. Patients were treated with vincristine, melphalan, cyclophosphamide and prednisolone every 4-6 weeks. In the combined treatment arm rIFN was administered concurrently with chemotherapy as well as during chemotherapy free intervals. The combined regimen effected 17/21 (80.9%) responses as compared to 19/27 (70.4%) responses in VMCP treated patients. Addition of rIFN to chemotherapy did not enhance hematologic toxicity. These findings suggest a somewhat higher rate of objective response in the VPMC + rIFN group, although a significant improvement in median survival by adding rIFN to conventional first line polychemotherapy in myeloma patients has not yet been achieved.

Combined alpha-2C-interferon/VMCP polychemotherapy versus VMCP polychemotherapy as induction therapy in multiple myeloma: a prospective randomized trial.
    Journal of biological response modifiers, 1989, Volume: 8, Issue:2

    Thirty-three previously untreated patients with multiple myeloma were randomized to either a combination of recombinant interferon-alpha-2C (rIFN-alpha-2C) plus vincristine/melphalan/cyclophosphamide and prednisone (VMCP) or VMCP chemotherapy alone. The combined regimen effected 67% responses and 26% minor responses, while 35 and 47% of VMCP-treated patients had a pathologically documented remission, respectively. Despite the somewhat earlier achievement and duration (12.0 vs. 8.0 months) of objective response, and the marginal survival benefit observed in the rIFN-alpha-2C + VMCP treatment arm, a significant improvement in therapeutic gain by adding a biologic response modifier to conventional first-line polychemotherapeutic drug treatment in myeloma patients has not yet been achieved. The combined regimen was well tolerated without unusual or unexpected toxic effects.

Alternating combination chemotherapy (VMCP/VBAP) is not superior to melphalan/prednisone in the treatment of multiple myeloma patients stage III--a randomized study from MGCS.
    European journal of haematology, 1989, Volume: 43, Issue:1

    86 previously untreated patients with multiple myeloma stage III entered a randomized trial comparing combination chemotherapy (VMCP/VBAP) (n = 42) with intermittent oral melphalan and prednisone (MP) treatment (n = 44). The treatment gropus were well comparable with regard to major prognostic factors. There was no statistically significant difference in the response rates, 52% (VMCP/VBAP) vs 61% (MP); in the response duration times, median 19 months vs 22 months, or in the survival times, median 24 months vs 28 months. However, survival of patients older than 65 years was significantly shorter in the VMCP/VBAP group (median 15 months) compared to the MP group (median 23 months) (p = 0.03). No significant difference in non-hematological or hematological toxicity was noted. The study further supports the notion that MP therapy should be used as primary standard treatment for patients with multiple myeloma.

VAMP followed by high dose melphalan and autologous bone marrow transplantation for multiple myeloma.
    Bone marrow transplantation, 1989, Volume: 4 Suppl 4

    Fifty previously untreated patients with myeloma were entered into a 2-phase treatment programme: vincristine, adriamycin and methyl prednisolone (VAMP) followed by high dose intravenous melphalan (HDM) with autologous bone marrow transplantation where possible. The complete remission rate of 50% was associated with very good quality of life and the reversal of humoral immunosuppression. Complete remission is important in younger patients with myeloma as it represents a first step in achieving long, symptom- free survival.

Melphalan/prednisone versus drug combinations for plasma cell myeloma.
    European journal of haematology. Supplementum, 1989, Volume: 51

    Reports of 13 prospective, randomized clinical trials comparing standard treatment with melphalan and prednisone (MP) versus various drug combinations in the treatment of myeloma patients are presented. These studies reveal that patients with Durie-Salmon Stage III disease respond significantly more frequently to MP and drug combinations than those with Stage I and II. Drug combinations may be more effective in inducing objective responses. The response rates were significantly better for the drug combinations in 3 of the 13 comparisons. There was little evidence that either form of treatment was superior in prolonging survival, for in one study the patients treated with a drug combination lived significantly longer than those treated with MP, while in another the reverse was true, and there was no difference in the survival of the two groups in the remaining 11 studies. In the Vth MRC myelomatosis trial, patients treated with a combination of adriamycin, carmustine, cyclophosphamide and melphalan are living significantly longer than those treated with melphalan alone, and this survival advantage persists after correction for the most important prognostic factor, beta 2 microglobulin. Attempts to increase the intensity of treatment by using syngeneic, allogeneic or autologous marrow transplantation to rescue patients following otherwise lethal chemoradiotherapeutic treatments, have not yet demonstrated conclusively that the myeloma clone can be eliminated by this form of treatment.

Induction treatment with alpha-interferon in multiple myeloma: an interim report from MGCS.
    European journal of haematology. Supplementum, 1989, Volume: 51

    A randomized study comparing melphalan/prednisone (M/P) therapy with MP + natural alpha-IFN in untreated patients with multiple myeloma stages II and III started April 1, 1986. By March 1989, 78 patients were evaluable in the MP group and 80 in the MP/IFN group. 48% of the MP patients achieved a response and 66% in the MP/IFN group (p = 0.04). Stage II patients responded better to MP/IFN (76%) than MP alone (47%) (p = 0.02), while no statistically significant difference was noted for stage III patients. 90% of the IgA myelomas responded to MP/IFN and 52% to MP (p = 0.02). Both for IgG and BJ myelomas the response rates of MP/IFN were higher than of MP, although the differences were not statistically significant. The observation period is still short. There was no difference in total survival between the two treatment groups. However, in patients less than or equal to 65 years a tendency to a longer survival was seen for those receiving the IFN combination (p = 0.12).

Induction and maintenance therapy in multiple myeloma: a multicenter trial of MP versus VCMP.
    European journal of cancer & clinical oncology, 1988, Volume: 24, Issue:6

    In a prospective multicenter trial, 320 untreated myeloma patients of stage II and III were randomized for remission induction into two groups receiving six monthly courses of either MP or VCMP treatment. Response rates were equal in both groups: 72% remission, 21% no change, 7% progress for patients evaluable by TCM changes and 56% remission, 11% no change, 33% progress for BJ- and non-secretory myelomas. The overall survival rate was 60% after 4 years. An unexpected finding was the significantly longer survival of MP treated patients compared to the VCMP group. After successful remission induction, patients were randomized into one group receiving maintenance treatment using the induction scheme q 8 weeks, and another group without further chemotherapy. Although patients in the latter group relapsed significantly earlier, differences between both groups concerning acquired resistance to first line therapy or survival have not been noticed to date.

Vincristine and prednisone prolong the survival of patients receiving intravenous or oral melphalan for multiple myeloma: Cancer and Leukemia Group B experience.
    Journal of clinical oncology : official journal of the American Society of Clinical Oncology, 1988, Volume: 6, Issue:9

    A total of 589 patients with previously untreated multiple myeloma were randomized to receive daily oral melphalan, pulse-dose intravenous (IV) melphalan, carmustine (BCNU), or lomustine (CCNU). All patients received an initial tapering course of prednisone (Pred). During week 22 (day 154), patients were randomized to receive or not to receive additional therapy with vincristine (VCR) (1 mg/m2) and prednisone (0.6 mg/kg/d for seven days) at 8-week intervals. The influence of VCR/Pred was determined in 302 patients who remained on study beyond 22 weeks after initial therapy. VCR/Pred converted a significant percentage of nonresponders to responders in patients treated with melphalan (55% v 19%, P = .002), but not in patients treated with a nitrosourea (48% v 23%, P = .06). Survival beyond week 22 was significantly longer following the addition of VCR/Pred in patients receiving melphalan (median, 35.3 months v 27.0 months; P = .003) but not in patients receiving BCNU or CCNU (median, 28.1 months v 26.2 months; P = .91). These differences were seen both for oral and IV melphalan. A trend for beneficial effect of VCR/Pred was definitely seen in the good-risk patients (P = .03) but only suggestive for poor-risk patients (P = .12). Following adjustment for VCR/Pred effects, there were no differences in the survival of patients receiving any of the four initial treatments.

Melphalan and prednisone plus total bone marrow irradiation as initial treatment for multiple myeloma.
    International journal of radiation oncology, biology, physics, 1988, Volume: 15, Issue:4

    Patients who have received radiation to localized areas of marrow eventually regenerate marrow in the irradiated area, if the dose is 2,400 centigrays (cGy) or less. This trial was designed to deliver a radiation dose of 1500 cGy to all marrow containing sites in patients with multiple myeloma, a technique we refer to as total bone marrow irradiation, or TBMI. Patients with previously untreated myeloma received 12 weeks of melphalan (L-PAM) and prednisone (pred) therapy. Four weeks later, sequential irradiation was administered using the 3-2 technique with rest periods to permit recovery from radiation-induced cytopenia. This was followed by electron beam irradiation of the rib and skull fields. Following completion of TBMI, patients were untreated until relapse. Twenty patients were entered. At entry 5, 8, and 7 patients had low, intermediate and high tumor cell loads, respectively. Two patients had a serum Ca in excess of 12 mg/dl; 3 had an increased creatinine. The median performance (ECOG) was 1. At week 16, immediately prior to TBMI, 5 of the 20 patients fulfilled the Myeloma Task Force criteria for response and 5 others had improved. Six patients did not begin the radiation therapy portion of the protocol. Three had rapidly progressive disease, one persistent leukopenia, one refused radiation therapy and one was withdrawn by his physician. Only 6 of the fourteen patients receiving the radiation treatment phase of the protocol were able to tolerate the intended course of 1500 cGy to all areas. Eight other patients received lower doses. Patients completing the radiation phase of the protocol failed to have further reductions in M-protein or improvement in other parameters beyond those obtained on the chemotherapy phase of the protocol. The median duration of response and survival was 12.0 and 42 months, respectively. We suggest possible reasons for the disappointing results of this trial and conclude that this approach to the primary treatment of myeloma holds little promise.

A randomized trial of maintenance versus no maintenance melphalan and prednisone in responding multiple myeloma patients.
    British journal of cancer, 1988, Volume: 57, Issue:1

    In order to assess the role of maintenance melphalan and prednisone (MP) in responding multiple myeloma patients, 185 eligible patients who responded to initial MP with stabilization for at least 4 months were randomized to either stop treatment and resume therapy at relapse or to continue MP until relapse. Time to first relapse was significantly shorter in the no maintenance group (P = 0.0011), however 57% of the no maintenance patients had a second response when MP was restarted and others had minor improvement. The time to final progression on MP, which reflects the duration of disease control by MP, was therefore longer for the no maintenance group (median = 39 months) compared to the maintenance group (median = 31 months) although the observed difference was not statistically significant (P = 0.086). Median survival from start of MP in the maintenance group (46 months) was also not significantly different than the no maintenance group (51 months) (P = 0.587). Multifactor analysis of the randomized patients demonstrated shorter total remission duration and shorter survival in patients who had an initially rapid response to therapy or a lesser reduction in serum M-protein concentration.

    In a prospective study by the German Myeloma Treatment Group, 320 untreated patients with multiple myeloma, stage II and III, were randomized into 2 groups receiving courses of either MP or VCMP as induction treatment every 6 months. 72% of the patients evaluable by TCM changes remitted, 21% showed a no change, and progress occurred in 7%. The corresponding results in BJ and nonsecretory myelomas were 56% remissions, 11% no change, 33% progress. The response rates were equal in both treatment groups. The overall survival was 60% after 4 years. However, MP-treated patients lived significantly longer than patients in the VCMP group. After successful remission induction, patients were randomized into one group with maintenance treatment using the induction scheme Q 8 weeks, and another group without further chemotherapy. Although the relapse rate of the latter group was significantly higher, differences between both groups concerning survival have not been observed.

An update of two randomized trials in previously untreated multiple myeloma comparing melphalan and prednisone versus three- and five-drug combinations: an Argentine Group for the Treatment of Acute Leukemia Study.
    Journal of clinical oncology : official journal of the American Society of Clinical Oncology, 1988, Volume: 6, Issue:5

    An update of two consecutive randomized studies in previously untreated multiple myeloma was performed. The first study (10-M-73) began in 1973; 150 patients were treated with melphalan and prednisone (MP) or semustine, cyclophosphamide, and prednisone (MeCP). In a second randomized study (3-M-77), begun in 1977, 260 patients were treated with MP or melphalan, prednisone, cyclophosphamide, semustine, and vincristine (MPCCV). A total of 27 of the 67 patients (40%) treated with MP and 33 of the 83 patients (40%) treated with MeCP showed a good response in protocol 10-M-73; 48 of 145 patients (33%) treated with MP and 51 of the 115 patients (44%) treated with MPCCV in protocol 3-M-77 obtained a good response (P is not significant). Median survival in protocol 10-M-73 was 30 months for MeCP and 38 months for MP. At 84 months, 19% and 9% remain alive, respectively. Median survival for protocol 3-M-77 was 44 months for those treated with MPCCV and 42 months for MP. At 60 months, 9% and 11% remain alive; this difference was not significant. Also, there was no survival difference for favorable or unfavorable prognostic groups among the four treatment arms of both protocols. It can be concluded, with a long-term follow-up of both protocols, that the combination of MP is as effective as the three- and five-drugs combinations, and in view of its simplicity and cost-saving advantages, it should be favored for initial therapy of multiple myeloma patients.

The use of interferon in the treatment of multiple myeloma.
    Seminars in oncology, 1987, Volume: 14, Issue:2 Suppl 2

    Almost all patients with multiple myeloma still relapse or become refractory in 2 to 3 years. Interferon (IFN) therapy has clearly influenced the levels of abnormal serum proteins in some patients. A multi-institutional phase II clinical trial used alfa-2b recombinant interferon (Intron A, Schering, Kenilworth, NJ) in 38 evaluable patients with relapsing and refractory multiple myeloma; two thirds of the patient population had received extensive prior treatment. Seven responded, of whom three continued to do so beyond 1 year--one with an ongoing complete remission. An additional 13 had at least a 25% decrease in abnormal paraproteins. Of nine patients who were initially refractory to chemotherapy, two responded to IFN. Of nine relapsing patients returned to chemotherapy following IFN therapy, six then responded. Thirty previously untreated patients with multiple myeloma were treated with IFN followed by melphalan and prednisone; of 24 evaluable patients, 18 responded with a median duration of 10+ months. Alfa-2b IFN apparently does not antagonize melphalan or prednisone, nor does it appear to worsen the response of the two drugs alone. Effectiveness of recombinant alfa-2b IFN in pretreated relapsing patients suggests additional trials are needed to study its effects in previously untreated patients. A significant number of patients who relapsed on their original chemotherapy and subsequent interferon will apparently respond to the reinstitution of chemotherapy.

A comparison of the incidence of the myelodysplastic syndrome and acute myeloid leukaemia following melphalan and cyclophosphamide treatment for myelomatosis. A report to the Medical Research Council's working party on leukaemia in adults.
    British journal of cancer, 1987, Volume: 55, Issue:5

    Twelve of 648 patients in the Medical Research Council's first two trials in myelomatosis have developed myelodysplasia or acute leukaemia. This corresponds to a 5-year actuarial prevalence of 3% and an 8-year prevalence of 10%. Patients were randomised to treatment with either melphalan or cyclophosphamide and the relative capabilities of these two drugs to cause these conditions were examined as a function of duration of treatment. A significant relationship with length of melphalan treatment was found but no relationship was observed for cyclophosphamide treatment. The amount of melphalan treatment given in various intervals before diagnosis of myelodysplasia or leukaemia was studied and it was found that the amount of treatment in the most recent 3-year period was the most important determinant of risk (P = 0.0001). It is estimated that the risk of haemopoietic neoplasia after 10 years of follow-up is about 3% for each year of melphalan treatment and that much of this risk will occur within three years of the last treatment.

Interaction of cimetidine with oral melphalan. A pharmacokinetic study.
    Cancer chemotherapy and pharmacology, 1987, Volume: 20, Issue:2

    The effects of pretreatment with cimetidine (200 mg three times daily, 400 mg at night) on the pharmacokinetics of oral melphalan (10 mg) have been investigated in patients with multiple myeloma. Cimetidine pretreatment reduced the bioavailability of oral melphalan by approximately 30% (P less than 0.05). The elimination rate of melphalan from plasma was significantly increased by cimetidine (P less than 0.05), the half-life being reduced from 1.94 +/- 0.55 h to 1.57 +/- 0.53 h. Cimetidine appeared to reduce the interindividual variability in melphalan absorption, but at the cost of reduced bioavailability.

Treatment of multiple myeloma with an intensive 5-drug combination or intermittent melphalan and prednisone; a randomised multicentre trial. Finnish Leukaemia Group.
    European journal of haematology, 1987, Volume: 38, Issue:1

    In a randomised multicentre trial a combination of methylprednisolone, vincristine, CCNU, cyclophosphamide and melphalan (MOCCA) was compared with intermittent melphalan and prednisone (MP) as primary treatment in multiple myeloma. In the MP arm the refractory or relapsed patients were treated with regimen MOCCA. The MOCCA arm produced a response rate of 75% among 64 patients and the MP arm a response rate of 54% among 66 patients. The median survival was 41 months in the MOCCA arm and 45 months in the patients primarily randomised to the MP arm. The initial response to MOCCA improved the survival, while this effect was not statistically significant in the MP arm. The results show that the median survival does not increase if aggressive chemotherapy is employed as the first line treatment in multiple myeloma.

Consolidation and maintenance therapy in multiple myeloma: randomized comparison of a new approach to therapy after initial response to treatment.

    A randomized, controlled trial was initiated in 1977 to evaluate the impact of three alternative approaches to consolidation and maintenance therapy after initial maximal response for multiple myeloma. All patients were treated initially with BCNU, cyclophosphamide, and prednisone (BCP) until a designated level of response was achieved. Responders were randomly assigned to either melphalan and prednisone (MP); prednisone, Adriamycin (Adria Laboratories, Columbus, Ohio), azathioprine, and vincristine (PAIV), or no therapy until relapse, then treatment with BCP. Initial response rates were comparable with previous trials. A small number of incremental responses were observed with both MP and PAIV. Survival was the same for all three maintenance approaches and the same as that observed in our previous continuous BCP or MP therapy. Additional or consolidation/maintenance therapy of the type administered here appears to offer little advantage once an initial response has been achieved.

Results and further perspectives of plasmocytoma chemotherapy.
    Neoplasma, 1986, Volume: 33, Issue:2

    Polychemotherapy has improved prognostic parameters of survival in patients with plasmocytoma. The mean survival in patients given long-time prednisone and melphalan treatment is 20 months, in those given polychemotherapy over 30 months. In patients with a slow disease progression the combinations COPP and VMCP give satisfactory results in about 40%, but in a majority of patients more effective treatment is necessary. The authors compare the 5-year survival of two polychemotherapy groups with the prednisone and melphalan group. The mean survival after prednisone and melphalan was 33 months, after polychemotherapy (groups COPP, VMCP) 46 months and 57 months (VMCP + M2), respectively. Survival time was influenced by the clinical stage.

Improved survival duration with combination chemotherapy induction for multiple myeloma: a Southwest Oncology Group Study.
    Journal of clinical oncology : official journal of the American Society of Clinical Oncology, 1986, Volume: 4, Issue:8

    Four hundred forty previously untreated patients with active multiple myeloma were entered into a randomized trial (Southwest Oncology Group [SWOG] study 7927/28) comparing vincristine, melphalan, Cytoxan (Mead Johnson & Company, Evansville, Ind), and prednisone (VMCP) alternating with vincristine, BCNU, Adriamycin (Adria Laboratories, Columbus, Ohio) and prednisone (VBAP) with or without levamisole with vincristine, Cytoxan, and prednisone (VCP) with or without levamisole for induction therapy. The treatment groups were well balanced for all of the known major prognostic factors. Patients receiving VMCP-VBAP responded (greater than or equal to 75% regression) more frequently to induction therapy, both without (54%) and with (44%) levamisole v VCP without (28%) or with (28%) levamisole (P less than .001). In addition, patients receiving VMCP-VBAP (+/- levamisole) had a survival duration determined to be significantly increased by all forms of analysis: 48 and 33 months for VMCP-VBAP without and with levamisole v 29 and 26 months for VCP without and with levamisole (P = .011 overall). Levamisole did not improve response rates or survival duration (P greater than or equal to .1), nor did it prolong remission in the maintenance phase (P = .85). Analysis of SWOG study 7704/05 (updated April 1985) confirmed improved survival for combination therapy v MP, but no benefit for levamisole. The overall findings support the use of VMCP-VBAP as an excellent treatment option for remission induction in patients with active myeloma of all stages and prognostic categories.

Single, sequential, and multiple alkylating agent therapy for multiple myeloma: a CALGB Study.
    Journal of clinical oncology : official journal of the American Society of Clinical Oncology, 1986, Volume: 4, Issue:9

    Four intravenous (IV) alkylating agent regimens were tested in 615 previously untreated patients with multiple myeloma. Patients were randomized to receive melphalan, cyclophosphamide, and carmustine in combination (MCBP), sequentially (Seq-MCBP), or in combination with doxorubicin (MCBPA). The fourth group received IV melphalan (MP) as the only alkylating agent. All groups received a tapering dose of prednisone. Toxicity was similar for all regimens although the nadir of cytopenia was reached more quickly for the regime including melphalan only. Response as measured by reduction in myeloma protein or other parameters were similar for the four treatments. Survival was significantly poorer for the group receiving the alkylating agents in sequence. The survival of high tumor cell load patients who were azotemic was better in the groups treated with IV MP or with the combination of IV MCBP. In view of the simplicity and probable cost savings attached to single-agent treatment, a melphalan/prednisone regimen should be considered as initial therapy for all patients with myeloma.

Current results of a multicenter trial in multiple myeloma.
    Onkologie, 1986, Volume: 9, Issue:3

    257 untreated myeloma patients (stage II and III) were studied in a multicenter trial. The patients were randomized and received MP or VCMP therapy. No differences in remission rate could be found in both therapy arms. After successful remission induction those patients without maintenance therapy relapsed significantly earlier than those patients receiving maintenance therapy. In pilot studies an etoposide therapy was found ineffective and a multidrug therapy (VBAMDex) could induce high remission rates in high risk and pretreated patients.

Recombinant interferon alfa-2C versus polychemotherapy (VMCP) for treatment of multiple myeloma: a prospective randomized trial.
    European journal of cancer & clinical oncology, 1986, Volume: 22, Issue:9

    Forty-two previously untreated patients with multiple myeloma were entered in a prospective, randomised trial comparing recombinant interferon alfa-2C monotherapy with VMCP (vincristin, melphalan, cyclophosphamide and prednisolone). Both treatment arms were comparable for the stratification variables such as paraprotein type, stage of disease, and renal function. Rec. interferon effected 14% responses and 29% minor responses, while 57 and 32% of VMCP-treated patients achieved a pathologically documented remission (P less than 0.001). The time on initial treatment was significantly shorter in the IFN group (3.2 months) than in the VMCP group (7.6 months). In four patients in the IFN arm, primary treatment had to be changed according to progressive or severe stationary disease. Since all four patients responded to second line therapy (VMCP) no significant difference has been observed between the two groups in survival (median follow-up greater than 12 months). Despite this clear superiority of the conventional four-drug polychemotherapy, there was some suggestion that IFN might be particularly active in cases with low tumor-burden (stage I, II), and light-chain or IgA paraprotein type.

Multiple myeloma in central Norway 1981-1982: a randomized clinical trial of 5-drug combination therapy versus standard therapy.
    Scandinavian journal of haematology, 1986, Volume: 37, Issue:3

    67 previously untreated patients with multiple myeloma were entered on a randomized clinical trial to determine whether the use of combination chemotherapy including vincristine, carmustine, alkylating agents, and prednisone was more effective than conventional therapy with melphalan and prednisone. The treatment groups did not show significant differences with respect to major prognostic factors. With the 2-drug combination therapy and 5-drug combination therapy, 67 and 74% of the patients achieved remission, respectively. Moreover, no significant difference was found between the two treatment schedules in terms of median survival (30+ months). The survival curves for stage III patients treated with the two regimens did not differ significantly. After 12 months, patients who had achieved remission were randomized to have treatment discontinued or to have maintenance treatment. 7 of 15 patients on maintenance therapy relapsed, whereas 9 of 14 patients who had their therapy discontinued relapsed, and the survival of the two groups was similar.

Peptichemio, vincristine and prednisone versus melphalan and prednisone as induction therapy in multiple myeloma.
    European journal of cancer & clinical oncology, 1986, Volume: 22, Issue:7

    Seventy-five patients with previously untreated multiple myeloma were randomly treated with the association of Peptichemio, Vincristine and prednisone (PTC-VCR-P) or of melphalan and P (MPH-P) for first induction therapy. After induction, all responsive patients received MPH and P until relapse, while unresponsive patients received it until unequivocal evidence of disease progression was observed. A second induction therapy with PTC-VCR-P was then administered, except to patients resistant to this association at first induction (who received combination chemotherapy which included cyclophosphamide and adriamycin). The response rate was 58% in the PTC-VCR-P and 41% in the MPH-P group (P greater than 0.05). The PTC-VCR-P responsive patients experienced a median duration of response shorter than MPH-P responsive patients (20.3 vs 39.7, P = 0.041). Median survival from the start of treatment was 26.2 months in the PTC-VCR-P and 54.1 months in the MPH-P group of patients (P = 0.039). Stage I and II myelomas had the same response rate to PTC-VCR-P and to MPH-P, but their survival was shorter on PTC-VCR-P than on MPH-P (P = 0.014). Stage III myelomas responded more frequently to PTC-VCR-P than to MPH-P (P less than 0.02) and there was a trend to survive longer on PTC-VCR-P than on MPH-P (22.0 vs 12.5 months, P greater than 0.05).

Objective evaluation of the role of vincristine in induction and maintenance therapy for myelomatosis. Medical Research Council Working Party on Leukaemia in Adults.
    British journal of cancer, 1985, Volume: 52, Issue:2

    In the Medical Research Council's IVth trial in Myelomatosis the possible benefit of adding vincristine to first line treatment with intermittent melphalan and prednisone has been assessed. This was analysed in 530 patients who were randomly allocated to receive vincristine or not. Survival was not improved by the addition of vincristine. A total of 268 patients reached plateau phase on first line therapy. Of these 226 patients were rerandomised either to continue receiving first line therapy for a further year or to cease therapy. At the present time there is a slight but not significant survival advantage in the group which received no further treatment on reaching plateau.

Age and the treatment of multiple myeloma. Southeastern Cancer Study Group experience.
    The American journal of medicine, 1985, Volume: 79, Issue:3

    To determine the impact of age upon the response to treatment, survival, and toxicity of chemotherapy for multiple myeloma, the results of a large cooperative group trial were examined. Patients were randomly assigned to induction therapy with either carmustine, cyclophosphamide, and prednisone or melphalan and prednisone; patients with response received two years of treatment. The age distribution of patients in this trial compared with the incidence figures from the Surveillance Epidemiology and End Results (SEER) study shows a degree of under-representation of the oldest patient groups. Prognostic factors were evenly distributed over the age range and treatment groups. Older patients had responses and survival rates equivalent to younger patients and with both treatment regimens regardless of prognostic factor characteristics. Hematologic toxicity was no greater for the older group in either regimen despite the presence of a nitrosourea in one. Gastrointestinal toxicity was increased in the older patients who received the regimen of melphalan and prednisone. The study suggests that in myeloma and perhaps other such chemotherapy-responsive malignancies treated with moderately intense chemotherapy, without bone marrow ablation, elderly and younger patients have similar outcomes.

Treatment of multiple myeloma: a randomized study of three different regimens.
    Leukemia research, 1985, Volume: 9, Issue:8

    The results of an Italian multicentric trial for treatment of symptomatic Multiple Myeloma (MM) are reported. One hundred and thirty-three previously untreated patients were singled out at random for three different chemotherapy schedules: Melphalan plus Prednisone (M.P.) X 6 monthly cycles; Vincristine plus Melphalan plus Cyclophosphamide plus Prednisone (VMCP) X 6 monthly cycles; Peptichemio, Cyclophosphamide, BCNU. Drugs in this latter schedule were administered sequentially, for a period of six months. Criteria for response, progression and relapse were those of the Southwestern Oncology Group. Fifteen patients in MP chemotherapy (35%) and 20 patients in VCMP chemotherapy (46%) achieved an objective response (decrease of at least 50% in the synthesis index of Monoclonal Component (M.C.], while only 3 out of the other 21 patients assigned to the third schedule responded to treatment. No significant differences were noted in the survival curves in either of the three treatment groups. The 38 responding patients did not receive maintenance therapy; no significant difference was found in remission duration between patients in MP and VCMP arms, with a median duration of 16 months for the whole group. No statistical difference was observed between survival and remission curves of patients with a 'response' (M. spike reduction greater than 75%) and those with 'improvement' (M. spike reduction between 75 and 50%). The authors conclude that the inclusion of Vintristine in a combination chemotherapy does not produce clear survival benefits; a longer induction period (12 cycles) could allow a better differentiation between MP and VMCP regimens.

Aggressive combination chemotherapy in multiple myeloma. A multicentre trial. Finnish Leukaemia Group.
    Scandinavian journal of haematology, 1985, Volume: 35, Issue:2

    A one-armed multicentre trial was conducted in Finland during the period from Jan. 1979 to Feb. 1980 to document the possible beneficial effect of aggressive combination chemotherapy MOCCA on the remission induction and survival in multiple myeloma. The regimen MOCCA consisted of vincristine, methylprednisolone and 3 alkylating agents. Of the 50 patients eligible for the for study, 39 (78%) achieved at least a 50% response. 27 (54%) achieved an excellent response. The median survival time for all patients was 49 months from the initiation of the treatment, but 23 of the 33 patients whose myeloma protein had shown a greater than or equal to or greater than or equal to 75% reduction were still alive at 4 yr. Advanced clinical stage and irreversible renal damage had a negative prognostic value. After 12 months on regimen MOCCA the patients with a greater than or equal to or greater than or equal to 75% reduction in myeloma protein were allocated at random to receive MOCCA courses bimonthly or no further chemotherapy. The maintenance chemotherapy did not prolong remission or survival.

Phase III study of intermittent 5-drug regimen (VBCMP) versus intermittent 3-drug regimen (VMP) versus intermittent melphalan and prednisone (MP) in myelomatosis.
    Scandinavian journal of haematology, 1985, Volume: 35, Issue:5

    A prospective randomized trial in 96 patients with previously untreated myelomatosis was performed comparing 3 regimens of chemotherapy: (i) Intermittent vincristine, BCNU, cyclophosphamide, melphalan, and prednisone (VBCMP) to (ii) intermittent vincristine, melphalan and prednisone (VMP) to (iii) intermittent melphalan and prednisone (MP). Induction response rates and survival were similar in all 3 regimens. An improvement in relapse-free survival was observed by adding vincristine to MP, but this did not achieve statistical difference (p = 0.10). Patients given VBCMP fared slightly worse than those given VMP. The haematologic toxicity was similar in all 3 regimens, but the tolerability of VBCMP was lower. Although showing no statistical differences between the 3 treatment regimens, the results support the view that a combination of MP 'standard' induction therapy in MM with frequently administered vincristine has a trend towards postponing treatment failure due to development of resistance to melphalan.

[Interferon in the treatment of multiple myeloma].
    Acta medica Austriaca, 1985, Volume: 12, Issue:5

    The effect of recombinant interferon-alpha-2C monotherapy was compared with the efficacy of VMCP-polychemotherapy in 42 patients with multiple myeloma in a prospective randomized multicenter trial. IFN-treatment induced remissions (R) in 2 (14%) and partial remissions (PR) in 4 (29%) out of 14 evaluable patients. 7 patients remained stable. Polychemotherapy induced R in 11 (57%) and PR in 6 (32%) of 19 evaluable patients. 2 (11%) patients remained stable. IFN was preferentially active in patients with low tumor burden and patients with IgA paraprotein. The proportion of responders (R + PR) was significantly lower in the IFN-arm (43%) compared to the polychemotherapy group (89%; p less than 0,001).

Response rate and survival in myeloma patients receiving prednisone alone.
    Medical and pediatric oncology, 1985, Volume: 13, Issue:5

    Thirty-two evaluable good risk patients with multiple myeloma received a 70-day tapering course of prednisone beginning at a dose of 1.2 mg/kg/day. Forty-four percent of the patients demonstrated objective evidence of response to this treatment. Although the median time to disease progression for the prednisone-treated group was shorter than for patients randomized to receive prednisone with alkylating agents or who were treated with alkylating agent alone, the results from this trial indicate that prednisone, by itself, may produce objective responses. Caution must be used interpreting trials of new agents in myeloma when such treatments are combined with corticosteroid administration.

Analysis and management of renal failure in fourth MRC myelomatosis trial. MRC working party on leukaemia in adults.
    British medical journal (Clinical research ed.), 1984, May-12, Volume: 288, Issue:6428

    During March 1980 to February 1982, 73 out of 80 patients in renal failure admitted to the fourth MRC myelomatosis trial were managed by a planned policy of high fluid intake (greater than or equal to 3 1/24 h) in addition to receiving one of the two chemotherapeutic regimens being tested in the main trial. Patients were also randomised to receive either sodium bicarbonate to render their urine neutral or no supplement. Follow up continued till death or to April 1983. Of 49 patients who survived more than 100 days, 39 achieved reversal of their renal failure (18 complete, 21 partial). Recovery of renal function, as assessed by a fall in the serum creatinine concentration, was achieved even when light chain proteinuria persisted. Partial recovery of renal function was associated with prolonged useful life in several patients. In only 14 of the 80 patients studied was death directly attributable to renal failure. Survival of patients in the study was appreciably better than in equivalent groups of patients in other MRC trials in which less stringent policies of fluid intake were used. Patients randomised to receive alkali fared marginally better than the others, but the difference was not significant. These results show that in many cases patients with myelomatosis who develop renal failure may have this complication reversed by taking a high fluid intake. Furthermore, though light chain is an essential component of renal disease in these patients, other factors are also important and are accessible to treatment.

Chemotherapy for multiple myeloma.
    Cancer, 1984, Feb-01, Volume: 53, Issue:3

    The effects of eight different drug combinations were evaluated in 256 patients with multiple myeloma. The response rate and time to remission were superior from regimens that added both vincristine and Adriamycin (doxorubicin) to an alkylating agent-prednisone combination. There was no improvement in response rate or survival time from two alternating drug combinations evaluated in an attempt to achieve more marked tumor reductions and to delay the emergence of resistant subclones. The addition of levamisole during remission maintenance did not improve survival time. Results supported the utility of unmaintained remission follow-up in selected patients with marked reductions in myeloma cell mass.

The effect of BM 12.531 (azimexon) on natural killer cell activity in myeloma patients.
    European journal of cancer & clinical oncology, 1984, Volume: 20, Issue:3

    The 2-cyanaziridin derivative, azimexon (E), has previously been shown to have certain immunomodulatory properties. In particular, the induction of leukocytosis, the stimulation of delayed-type hypersensitivity reactions and the synergistic effect of azimexon and antibiotics in the control of lethal bacterial and fungal infections in mice prompted us to test azimexon as an adjuvant to chemotherapy in 14 myeloma patients. In a randomized double-blind cross-over study 3 X 600 mg of azimexon were added to one of two consecutive, identical chemotherapy courses consisting of melphalan/prednisone (MP) or vincristine/cyclophosphamide/melphalan/prednisone (VCMP). Chemotherapy was given during days 1-4 and azimexon or placebo were added on days 6, 10 and 14. Blood counts and natural killer (NK) cell testing were performed on days 0 and 21 of each course. With the exception of a transient taste irritation in two patients, azimexon caused no subjective side-effects. White blood cell counts were not altered by the drug; red blood cells and hemoglobin showed a borderline depression after azimexon. NK activities measured against three target cell lines (K562, IGR3, L1210) tended to increase after azimexon treatment. When added in vitro to NK assays azimexon caused a slight increase of NK activity at concentrations of 0.01-0.25 mu/ml, whereas concentrations above 1 microgram/ml were inhibitory. The increase of NK activity by azimexon was not due to the induction of interferon in the effector lymphocyte population.

A randomized trial of melphalan and prednisone versus melphalan, prednisone, cyclophosphamide, MeCCNU, and vincristine in untreated multiple myeloma.
    Journal of clinical oncology : official journal of the American Society of Clinical Oncology, 1984, Volume: 2, Issue:7

    In a randomized study with 234 previously untreated patients with multiple myeloma, 129 were treated with melphalan (8 mg/m2 perorally for four days) and prednisone (40 mg/m2 perorally for seven days, both every four weeks) and 105 with melphalan and prednisone at the same doses plus cyclophosphamide (600 mg/m2 intravenously every four weeks), MeCCNU (100 mg/m2 PO every eight weeks), and vincristine (MPCCV, 0.6 mg/m2 IV every four weeks). A total of 49 (38%) of the 129 patients treated with melphalan and prednisone (MP) and 48 (46%) of the 105 patients treated with MPCCV showed good response (GR) (P not significant); the overall response rates were 58% and 70%, respectively. Thirty-seven percent of the MP group and 39% of the MPCCV group remain alive at 48 months from first treatment (P not significant). The estimated 48-month survival from first treatment, according to different prognostic factors at diagnosis, in both groups was as follows: stage 1,56%; stage II, 46%, and stage III, 23% (I and II v III P less than .001). Survival at 48 months according to response was GR, 68%; partial response (PR), 33%; and null, 16% (GR v null, P less than .0005; GR v PR, P less than .0005). Survival according to renal function was 43% for a creatinine level less than 2 mg/100 mL and 27% for a creatine level greater than or equal to 2 mg/100 mL (P less than .0005). No significant difference has been found between the two treatment schedules in terms of response rate and survival time, in any stage of disease.

Human leukocyte interferon and intermittent high-dose melphalan-prednisone administration in the treatment of multiple myeloma: a randomized clinical trial from the Myeloma Group of Central Sweden.
    Cancer treatment reports, 1984, Volume: 68, Issue:11

    In a randomized clinical trial intermittent high-dose melphalan/prednisone (MP) treatment has been compared with human leukocyte interferon (IFN) administration. Three to 6 X 10(6) IU of IFN was given im daily. Therapy was continued to progression of the disease. Fifty-five patients were randomized to receive MP and 75 were randomized to receive IFN. Forty-four percent of the patients receiving MP responded to therapy as opposed to only 14% of the patients receiving IFN (P less than 0.001). This difference was mainly due to a low response rate in IFN-treated IgG myelomas, while the response rate for IgA and Bence Jones myelomas did not differ significantly between the two treatment groups. Median duration of response was shorter for IFN-responding patients (23 months) as compared to patients in the MP group (35 months). During follow-up, second-line therapy was given more frequently in the IFN group (91%) than in the MP group (59%). Time on initial treatment was significantly shorter in the IFN group (3 months) than in the MP group (19 months). Since more patients responded to second-line therapy in the IFN group than in the MP group, total survival did not differ significantly between the two groups.

Therapy for multiple myeloma with alternating non-cross-resistant chemotherapy combinations: heterogeneity of tumor responsiveness.
    Cancer treatment reports, 1984, Volume: 68, Issue:12

    Thirty-five previously untreated patients with multiple myeloma were treated with a 60-week course of alternating, potentially non-cross-resistant chemotherapy combinations (melphalan and prednisone; vincristine, cyclophosphamide, doxorubicin, and prednisone; and carmustine, melphalan, and prednisone), alternating every 15 weeks in an attempt to prevent the development of drug resistance. The overall objective response rate (greater than 50% decrease in M protein) was 60% and six patients (17%) had a complete disappearance of the M protein. After 60 weeks, chemotherapy was discontinued in 17 responding or stable patients until relapse occurred from 4 to 39 months later (median, 12 months). Patients relapsing late (greater than 12 months after discontinuation of therapy) responded more frequently than those relapsing earlier to the reinstitution of the same chemotherapy program. The overall response rate and the actuarial median survival of 26 months in the 35 patients do not differ from the results reported recently with nonalternating combinations given until clinical tumor progression. The failure of this study to prolong survival by using alternating regimens may be due to (a) the likely possibility that the initial two regimens are not actually non-cross-resistant in most myeloma patients, and (b) the long interval between the alternating regimens, particularly in the face of the low response rate to the initial regimen of melphalan and prednisone.

    A randomized controlled trial was initiated in 1972 to compare two chemotherapeutic regimens [1-3-bis (2-chloroethyl) 1-nitrosourea (BCNU), cyclophosphamide, and prednisone versus melphalan and prednisone], to determine whether the two regimens are cross-resistant, and to evaluate the effectiveness of sodium fluoride, vitamin D, calcium gluconate, and fluoxymesterone in the promotion of bone healing. Initial responses (50%) and survival (36 mo median) for patients treated with the two chemotherapeutic regimens were the same. Patients on either regimen who failed to respond after 6 mo had a very low response rate to the alternative regimen (approximately 10%). Initially responding patients were randomly assigned to either an active drug regimen (sodium fluoride, vitamin D, calcium gluconate, fluoxymesterone) or placebo tablets. There was no significant difference in the low percentage of patients demonstrating bone improvement. Thus, the BCNU, cyclophosphamide, prednisone regimen is as effective as melphalan and prednisone. Fluoride, calcium, vitamin D, and androgenic steroids should not be routinely recommended in myeloma, as they seem to add little to effective chemotherapy and may contribute to morbidity.

Intermittent high-dose melphalan/prednisone vs continuous low-dose melphalan treatment in multiple myeloma.
    European journal of cancer & clinical oncology, 1983, Volume: 19, Issue:4

    Patients with newly diagnosed multiple myeloma were randomly allotted to an intermittent high-dose melphalan/prednisone (MP) treatment (120 patients) or a continuous low-dose melphalan (M) regimen (99 patients). The median observation time was 59 months (range 33-84). Response to therapy was obtained in 45% of the MP group and 31% of the M group (P less than 0.05). No significant difference in response with regard to clinical stage was noted. Median survival was 36 months in the MP group and 29 months in the M group. Survival was longer in stage I and II myeloma than in the stage III cases, at least in the MP group. The median and 5-yr survival rates in stages I and II were significantly better in the MP than in the M group. Response to therapy was associated with length of survival, median survival being 62 months in responding patients and 20 months in non-responders. The MP and M groups did not differ in this respect.

The pharmacokinetics of melphalan in patients with multiple myeloma: an intravenous/oral study using a conventional dose regimen.
    European journal of clinical pharmacology, 1983, Volume: 24, Issue:2

    The pharmacokinetics of melphalan have been studied after intravenous and oral dosing (10 mg) in 6 patients with multiple myeloma. After intravenous administration, mean plasma t0.5 alpha was 8.0 +/- 2.3 min, t0,5 beta was 63.3 +/- 8.7 min, and total systemic clearance was 510.4 +/- 57.9 ml/min. After oral administration, the drug was rapidly absorbed (lag-time = 18.4 +/- 3.7 min, absorption rate constant = 0.0547 +/- 0.0166 min-1, Tmax = 59.3 +/- 6.6 min), but there was considerable variation in its bioavailability (61.5 - 102.0% mean 78.3 +/- 6.3%). Variability in drug absorption may be responsible, at least in part, for variation in response to this drug.

Phase III study of intermittent carmustine (BCNU), cyclophosphamide, and prednisone versus intermittent melphalan and prednisone in myeloma.
    Cancer treatment reports, 1982, Volume: 66, Issue:6

    A prospective randomized trial in patients with previously untreated multiple myeloma was performed comparing carmustine (BCNU), cyclophosphamide, and prednisone (BCP) to melphalan (Alkeran) and prednisone (AP). Induction response rates, remission duration, and survival were similar with both regimens. Hematologic toxicity was greater with AP. Crossover studies in patients who relapsed did not illustrate any significant activity with either drug treatment program. Therefore, BCP can be utilized as initial therapy in myeloma because of comparable remission rates and less hematologic toxicity.

Multiple myeloma resistant to melphalan: treatment with doxorubicin, cyclophosphamide, carmustine (BCNU), and prednisone.
    Cancer treatment reports, 1982, Volume: 66, Issue:3

    Sixty-five patients with multiple myeloma resistant to melphalan were randomized to receive cyclophosphamide, doxorubicin (Adriamycin), and prednisone (CAP) (30 patients) or carmustine (BCNU), doxorubicin, and prednisone (BAP) (35 patients). Objective responses occurred in two patients in the CAP group and in seven in the BAP group. Indirect responses were noted in seven additional patients in the CAP group and in six additional patients in the BAP group. Toxic effects consisted mainly of leukopenia and thrombocytopenia. Median survival did not differ between the two treatment groups (CAP, 8.4 months; BAP, 7.7). Objective responders had a longer survival than nonresponders (14.5 vs 7.7 months).

Influence of renal failure on myelosuppressive effects of melphalan: Cancer and Leukemia Group B experience.
    Cancer treatment reports, 1982, Volume: 66, Issue:3

    The influence of renal insufficiency on melphalan-induced myelosuppression was examined during the initial 10 weeks of treatment in 295 patients with multiple myeloma. Patients were randomized to receive either oral melphalan (0.15 mg/kg/day for 7 days, followed by 0.05 mg/kg/day after recovery from the wbc count nadir) or iv melphalan (16 mg/m2 every 2 weeks for four doses, followed by a single dose every 4 weeks). All patients received a 6-week tapering course of prednisone. Patients with renal insufficiency (BUN greater than or equal to 30 mg/100 ml) had a significantly higher frequency of severe leukopenia (less than or equal to 1000 cells/mm3) following iv melphalan than did patients with normal renal function (50% vs 15%, respectively; P = 0.007). The latter effect resulted in an increased frequency of drug-related deaths secondary to infection. The frequency of severe thrombocytopenia (less than or equal to 25,000 cells/mm3) was also greater in patients with renal failure following iv melphalan therapy. Reduction of iv melphalan dose to 50% in patients with elevated BUN reduced the frequency of these complications to levels that were not significantly different from those observed in patients with normal renal function. The frequency of severe myelosuppression was independent of renal function in patients receiving oral melphalan. Possible explanations for these findings are discussed.

Comparison of oral melphalan, CCNU, and BCNU with and without vincristine and prednisone in the treatment of multiple myeloma. Cancer and Leukemia Group B experience.
    Cancer, 1982, Nov-01, Volume: 50, Issue:9

    A total of 361 evaluable patients with previously untreated multiple myeloma were randomized to receive oral melphalan (0.15 mg/kg/day for seven days, followed by 0.05 mg/kg/day after recovery from the nadir of the leukocytes), BCNU (150 mg/m2 intravenously every six weeks) or CCNU (100 mg/m2 orally every six weeks). All patients received a tapering six-weeks) or CCNU (100 mg/m2 orally every six weeks). All patients received a tapering six-week course of prednisone starting at 0.8 mg/kg for the first two weeks. At week 22, one-half of the patients were randomized to receive vincristine (1 mg/m2) and prednisone (0.6 mg/kg for seven days) every two months in addition to previous therapy. The melphalan treated patients showed a significantly higher overall objective response frequency (59%), according to Myeloma Task Force criteria, when compared to those treated with BCNU (40%) or CCNU (42%). The survivals for all patients were not statistically different for the three treatment programs. However, the good-risk patients treated with melphalan had significantly longer survival (P = 0.02) than the equivalent patients who received BCNU or CCNU. The addition of vincristine and prednisone at week 2 did not significantly increase the percentage of subsequent objective responses or prolong the subsequent survival of any treatment group. It is concluded that oral melphalan is superior to BCNU and CCNU in producing objective responses and in prolonging survival in good risk patients.

Comparison of two combination chemotherapy regimens for multiple myeloma: methyl-CCNU, cyclophosphamide, and prednisone versus melphalan and prednisone.
    Cancer treatment reports, 1980, Volume: 64, Issue:1

    Of 139 evaluable and previously untreated patients with multiple myeloma, 67 received methyl-CCNU-cyclophosphamide-prednisone (group A) and 72 received melphalan-prednisone (group B); 48% and 33% respectively had good responses and the overall response rates (good plus partial) were 75% and 65% for groups A and B respectively. The survival curves for both groups of patients were similar, with a median survival of 32 months. At 36 months, 70% of those patients who obtained good response were alive, 29% of those with partial response were alive, and 13% of those with no response were alive. The clinical staging system described by Durie and Salmon shows a good prognosis for stage I patients, with 80% remaining alive at 48 months, while the survival curves for stage II and III patients were similar, with 33% and 28% respectively remaining alive at 48 months. The combination of methyl-CCNU-cyclophosphamide-prednisone is not more effective in terms of response rate or duration of survival than melphalan-prednisone.

Report on the second myelomatosis trial after five years of follow-up. Medical Research Council's Working Party on Leukaemia in Adults.
    British journal of cancer, 1980, Volume: 42, Issue:6

    Three hundred and seventy-two patients were randomized between 3 regimens of chemotherapy: cyclophosphamide, intermittent melphalan, and melphalan with prednisone, and were followed up to death or for at least 5 years. There was no difference in survival between the treatments, either overall or in any subgroup of patients. Therefore, the choice among these 3 treatments should be guided by the patient's comfort and convenience. The most important prognostic feature at presentation was the quality of renal function. It was possible to define good, intermediate and poor renal-function groups which were highly correlated with prognosis (X2 for trend = 62.6). The haemoglobin level at presentation was strongly correlated with prognosis among patients in the good renal-function group. Among 107 patients who presented with good renal function and with haemoglobin above 100 g/l, the 5-year survival was 43%. Other prognostic features were much less important when account was taken of renal function and haemoglobin level.

Treatment comparisons in the third MRC myelomatosis trial. Medical Research Council's Working Party on Leukaemia in Adults.
    British journal of cancer, 1980, Volume: 42, Issue:6

    Results after an average follow-up of 3 years are presented on 485 patients in the 3rd MRC therapeutic trial in myelomatosis. The 353 non-azotaemic patients (199 now dead) were randomized between i.v. cyclophosphamide (CY) and oral melphalan with prednisone (M & P). THose treated with M & P fared slightly, but non-significantly, better. The 132 azotaemic patients (111 now dead) were randomized between i.v. CY and a 4-drug regimen, and both groups fared equally badly. Finally, after one year of the allocated treatment, 297 survivors (126 now dead) were randomized either to stop all treatment until evidence of relapse was obtained, or to continue treatment with azathioprine and vincristine, interrupted every 3 months for a course of the first-allocated treatment. The overall results suggested that maintenance therapy was beneficial, though the results were not statistically significant. Most of the difference was found among the few patients with unfavourable prognostic features who survived one year and were eligible for this randomization. In this, as in the two previous MRC trials, no striking differences have emerged between the therapeutic effects of different schedules of melphalan and/or CY. Consequently, a regimen of intermittent oral melphalan (with or without prednisone) seems satisfactory, because it is among the least toxic and most convenient. The 4th myeloma trial, now beginning, seeks to discover whether the addition of vincristine to the regimen can improve these results.

Hypersensitivity reactions to iv melphalan during treatment of multiple myeloma: Cancer and Leukemia Group B experience.
    Cancer treatment reports, 1979, Volume: 63, Issue:3

    Ten patients developed allergic reactions to iv melphalan (L-PAM) during therapy for multiple myeloma. The incidence of such reactions was 2.4% among 425 patients receiving iv L-PAM with or without other drugs and 3.9% among 255 patients receiving iv L-PAM alone. Only one such reaction was demonstrated in 294 patients who initially received oral L-PAM. The median day of first reaction to iv L-PAM was Day 222 (range, Days 44-909) and the median total dose prior to a reaction was 185 mg (range, 51-250 mg). Of five patients who subsequently received oral L-PAM, four developed a reaction similar to that experienced with the iv drug.

Improved survival of increased-risk myeloma patients on combined triple-alkylating-agent therapy: a study of the CALGB.
    Blood, 1979, Volume: 54, Issue:1

    Two hundred fifty-two previously untreated evaluable patients with multiple myeloma were entered into a study testing a regimen of three intravenous alkylating agents, melphalan, cyclophosphamide, and carmustine (BCNU), given in combination (BCMP) against a regimen employing oral melphalan (MP). Both regimens included a tapering course of prednisone. Objective responses based on the Myeloma Task Force criteria were significantly more frequent in the group receiving BCMP. Survival for the entire group of BCMP-treated patients was not significantly better than that for MP-treated patients (p = 0.62). However, when the survival of the poor-risk (high tumor cell load) group of patients treated with BCMP was compared with the survival of the poor-risk (high tumor cell load) group of patients treated with MP, an improvement in survival attributable to BCMP therapy was seen (p = 0.049 and 0.02, respectively). In the good-risk (low and intermediate tumor cell load) group, BCMP treatment resulted in a trend toward poorer survival, but this did not achieve statistical significance (p = 0.080 and 0.23, respectively). These results indicate that optimal therapy in myeloma may be dependent on the extent of disease at the time of first treatment. Additional studies to explore the effects of treatment intensity and duration are needed in order to design improved myeloma treatment based on the patient's extent of disease.

Multiple myeloma resistant to melphalan: treatment with cyclophosphamide, prednisone, and BCNU.
    Cancer treatment reports, 1979, Volume: 63, Issue:8

    Eighty-nine patients with multiple myeloma resistant to melphalan were randomized to receive cyclophosphamide plus prednisone (CP) (47 patients) or cyclophosphamide plus BCNU plus prednisone (CBP) (42 patients). No differences were detected in the two groups prior to therapy. Objective responses occurred in three (7%) of the CP patients and in seven (17%) of the CBP patients. About 40% of the patients in each group achieved some response. Toxic reactions consisted mainly of leukopenia and thrombocytopenia. Median survival was not different in the two groups. The median survival time was 31 months among those patients with an objective response and 9.4 months among those without an objective response. The addition of BCNU to CP increased the frequency of objective response, but not significantly. This triple combination (CBP) cannot be recommended.

The chemotherapy of plasma-cell myeloma and the incidence of acute leukemia.
    The New England journal of medicine, 1979, 10-04, Volume: 301, Issue:14

    Previously untreated patients with myeloma were randomized to initial treatment with melphalan and prednisone (and to cyclophosphamide or carmustine if relapse or progression occurred)(Group A, 125 patients), melphalan, cyclophosphamide, carmustine and prednisone in alternating (Group B, 123 patients) or concurrent (Group C, 116 patients) schedules. The groups were similar with respect to known prognostic factors. Response rates and survival were also similar. We were unable to identify a subgroup of patients who responded or survived better on melphalan-cyclophosphamide-carmustine and prednisone than on melphalan and prednisone. We conclude that the combination of the four drugs is not better than melphalen and prednisone for inducing responses or prolonging the survival of patients with myeloma. Myelomas producing only gamma chains have a poorer prognosis (P greater than 0.001) than IgG, IgA, or kappa myeloma. Acute leukemia has developed in 14 patients. The actuarial risk of developing acute leukemia, has increased rapidly to 17.4 per cent at 50 months.

Combination therapy for multiple myeloma.
    Cancer, 1977, Volume: 40, Issue:6

    The effect of six different chemotherapy regimens were evaluated in 462 previously untreated patients with multiple myeloma. In comparison with other treatments, drug combinations that included vincristine and were given at 3-week intervals were associated with higher response rates and longer survival times. No gain was noted from the use of Adriamycin or from combinations of alkylating agents unless vincristine was given and the treatment intervals were short. Seventy-one responding patients were allocated at random to maintenance treatment with intermittent courses of either azathioprine--prednisone or a combination of melphalan--cyclophosphamide--carmustine (BCNU)--prednisone. The survival time was not prolonged with either maintenance treatment in comparison with that for responding patients continued on other therapies or on no therapy in previous studies. Attempts to reduce tumor was maximally with a change in the therapeutic modality, such as with immunotherapy or radiotherapy, remain to be evaluated.

Multiple-myeloma bone disease. The comparative effect of sodium fluoride and calcium carbonate or placebo.
    The New England journal of medicine, 1975, Dec-25, Volume: 293, Issue:26

    A randomized double-blind study was carried out in 26 patients with multiple myeloma to compare the therapeutic effect of sodium fluoride (50 mg twice daily) plus calcium carbonate (1 g four times daily) and placebo. All patients also received melphalan and prednisone for one week every six weeks. Bone biopsies for microradiography and histology, and videodensitometry as well as conventional roentgenograms, 99mTc-polyphosphate bone scans, and bone densitometry of the mid and distal radius, were done initially and one year after therapy. Microradiography and videodensitometry studies revealed significant increases in bone formation (P less than 0.01) and bone mass (P less than 0.005) in the fluoride-calcium group. Bone trabeculae appeared thickened on roentgenograms of six of 13 fluoride-calcium-treated patients (P less than 0.02). Technetium bone scans and bone densitometry determinations proved insensitive for detection of skeletal changes. Fluoride calcium should be considered a useful adjunct in the treatment for multiple myeloma.

Remission maintenance therapy for multiple myeloma.
    Archives of internal medicine, 1975, Volume: 135, Issue:1

    The effects of various regimens of melphalan combination chemotherapy were evaluated in 508 patients with multiple myeloma. No value was confirmed from the addition of procarbazine or vincristine sulfate to melphalan-prednisone combinations. Ninety-six patients who responded to treatment were allocated at random to one of three maintenance regimens, namely intermittent courses of carmustine with prednisone, continued courses of melphalan with prednisone, or no chemotherapy. There were no differences in the frequency of relapse, the remission duration, or the survival time among these maintenace groups. The frequencies of pneumonia and herpes zoster were higher in patients receiving continued chemotherapy. Continued melphalan-prednisone chemotherapy after the first year is of no major value to responding patients with multiple cyeloma. Attempts to reduce tumor mass maximally with a change in therapy are justified.

    A randomized study compared the response of patients with multiple myeloma to chlorambucil, melphalan, and azathioprine. All patients also received a combination of prednisone and fluoxymesterone. Seventy-three of 86 patients entered on the study could have evaluations. The results indicate that melphatan produced more responses than either azathioprine or chlorambucil, but responses to both of these agents were observed. No difference was noted between survival curves for patients with no poor-risk factors as compared to those having at least one poor-risk factor. The only poor-risk factor affecting survival in this group of patients was the blood urea nitrogen level.

Sequential therapy compared with combination therapy in multiple myeloma.
    Archives of internal medicine, 1975, Volume: 135, Issue:1

    A timed sequential chemotherapeutic regimen for multiple myeloma was desinged, based on plasma cell kinetics. A randomized study comparing this regimen with the combination of intermittent melphalan and prednisone was started after an adequate pilot study. Studies with tritiated thymidine labeling and mitotic indexes were performed on patients treated with sequential therapy. Of 13 patients treated with the combination therapy, the responses were as follows: two, objective improvement; nine, subjective improvement; and two, no responses. Of nine patients treated with sequential therapy, the responses in six patients who could have evaluations were as follows: one, objective improvement; two, subjective improvement; one, no response; one, with progressive disease; and one, cardiac death. The two studies showed differences in pertubation of cell kinetics of myeloma that may be related to exponential growth and immunoblobulin types.

Prognostic factors in multiple myeloma.
    Cancer, 1975, Volume: 36, Issue:4

    The effect of certain disease parameters on remission and survial time was evaluated in 482 patients with multiple myeloma treated with intermittent courses of melphalan-prednisone combinations. Increasing degrees of anemia, hypercalcemia, azotemia, and high serum myeloma protein levels were associated with progressive lifespan shortening. The short survival of patients with anemia and hypercalcemia was associated with short remissions in responding patients with these abnormalities. The extent of tumor mass was defined from specific laboratory parameters reported by Durie to be associated with large numbers of plasma cells. More advanced stages of myeloma were associated with higher frequencies and degrees of normal immunoglobulin depression. The response rate was not affected by the tumor mass grade, but increasing tumor mass was associated with a shorter lifespan. Greater degrees of tumor reduction were associated with longer remission and survival times. Patients in whom a marked tumor reduction was rapid had shorter survival and remission times than patients who responded more slowly.

The use of low-dose prednisone and melphalan in the treatment of poor-risk patients with multiple myeloma.
    Medical and pediatric oncology, 1975, Volume: 1, Issue:3

    A study was designed to evaluate the effectiveness of prednisone therapy in poor-risk patients with multiple myeloma. Patients were treated with melphalan alone or in combination with prednisone at doses of either 0.6 mg/kg or 0.3 mg/kg. The group of patients receiving melphalan and prednisone 0.6 mg/kg had significantly improved responses in hemoglobin, lowering of the M-protein concentration, and reduction of azotemia. Significant benefits attributable to prednisone were not demonstrated in the group receiving 0.3 mg/kg. Good responses have been shown to produce improved survival. The combination of melphalan and prednisone is effective in producing good responses, but the dose of steroids is important. A dose of prednisone of 0.6 mg/kg in gradually decreasing doses has been found to be effective in production of good responses, especially in the uremic patient.

Combination therapy for myelomatosis.
    British medical journal, 1974, Dec-07, Volume: 4, Issue:5944

    Twenty-eight patients with multiple myeloma have been treated with a quadruple chemotherapeutic regimen consisting of 1, 3 bis (2-chloroethyl)-1-nitrosourea (BCNU), cyclophosphamide, melphalan, and prednisolone. Nineteen new patients and nine who had escaped from previous single-agent therapy were included in the study. The results to date, on eight criteria of response, seem to be superior to those obtained from previous chemotherapeutic regimens. The study has been in progress for 18 months and only three patients have died. Only one who had not received previous therapy died, and she had complicating hyperparathyroidism, which almost certainly contributed to her death.

    UNTREATED PATIENTS SUFFERING FROM MYELOMATOSIS WERE ALLOCATED AT RANDOM FOR TREATMENT BY THE DAILY ORAL ADMINISTRATION OF EITHER CYCLOPHOSPHAMIDE OR MELPHALAN: 141 received cyclophosphamide and 133 melphalan. The trial began on 1 October 1964 and the intake of patients continued until 31 July 1968. The statistical analysis includes follow-up of the surviving patients to 31 May 1970.The most important single factor affecting the prognosis was the blood urea concentration at presentation. The median survival of the 125 patients whose blood urea concentration was less than 40 mg/100 ml was 33 months, compared with 20 months for the 96 patients whose blood urea concentration was 40-79 mg/100 ml and two months for the 55 patients whose blood urea concentration was 80 mg/100 ml or more.The median survival periods of the 114 patients in the cyclophosphamide group and of the 105 in the melphalan group whose blood urea concentration at presentation was less than 80 mg/100 ml were 27 and 23 months respectively. The difference is not statistically significant.

Melphalan on day -1 versus day -2 in patients with plasma cell disorders undergoing autologous stem cell transplant.
    Journal of oncology pharmacy practice : official publication of the International Society of Oncology Pharmacy Practitioners, 2023, Volume: 29, Issue:6

    High-dose melphalan-based autologous stem cell transplant (ASCT) remains a standard of care for plasma cell disorders (PCDs). Currently, there is variability in the literature surrounding the timing of melphalan administration to avoid potential cytotoxic effects, although the administration has been safely proposed when given at least 8 hours prior to stem cell infusion. The objectives of this study were to assess differences in safety and efficacy outcomes between day -1 and day -2 single-dose melphalan administration in patients undergoing ASCT for PCDs. A retrospective chart review was performed at our institution comparing patients receiving melphalan on day -1 to an equal number of patients receiving melphalan on day -2. The primary endpoint was time to neutrophil engraftment from stem cell infusion. Univariate analyses were performed. Mean time to neutrophil engraftment from stem cell infusion was identical at 10.7 days for both cohorts (

Bridging advanced myeloma patients to subsequent treatments and clinical trials with classical chemotherapy and stem cell support.
    Bone marrow transplantation, 2023, Volume: 58, Issue:1

    Rapidly progressing relapsed/refractory multiple myeloma (RRMM) patients with compromised marrow have limited treatment options. Thus, non-myeloablative chemotherapy with a stem cell boost (SCB) may provide disease control and hematopoietic improvement as bridge to subsequent therapies. We identified 96 patients who received a SCB between January 2011 and December 2019 at the Mount Sinai Hospital. Patients had a median age of 64 years, received a median of 7 prior lines of therapy and 68 and 42% were triple-class and penta-drug refractory, respectively. Chemotherapy included melphalan (MEL) (n = 16), melphalan + carmustine (BCNU/MEL) (n = 52) or a variant of DCEP (dexamethasone, cyclophosphamide, etoposide, cisplatin) (n = 28). Median time to neutrophil recovery was 10 days and was significantly lower with DCEP (8 days) compared to MEL and BCNU/MEL (10-11 days) (p = 0.0047). Time to progression, progression-free survival and overall survival were 3.19, 2.7 and 8.38 months, respectively. The BCNU/MEL group had the highest response rate of 85% (p = 0.05), clinical benefit rate of 94% (p = 0.0014), progression-free survival of 3.3 months (p = 0.4) and overall survival of 8.7 months (p = 0.5). Sixty-six patients (69%) were bridged to new lines of therapy, including clinical trials. Non-myeloablative chemotherapy with SCB provides rapid disease control and marrow recovery with potential to receive further therapy.

Comparison of Patient Outcomes With Two Different Formulations of Melphalan as Conditioning Chemotherapy for Autologous Hematopoietic Cell Transplantation in Multiple Myeloma.
    Clinical lymphoma, myeloma & leukemia, 2023, Volume: 23, Issue:2

    High-dose melphalan (HDM) with autologous hematopoietic cell transplantation (AHCT) after induction chemotherapy is considered standard of care in transplant-eligible patients with newly-diagnosed multiple myeloma (MM). Alkeran melphalan has propylene glycol as a solvent (PG-mel) while Evomela utilizes a propylene glyclol-free formulation (PGF-mel). We evaluated the differences in efficacy and safety of the 2 formulations as there are no prospective head-to-head trials.. We retrospectively reviewed the medical records of all 259 consecutive MM patients who received PGF-mel as part of HDM-AHCT at The Ohio State University (OSU). The comparator group was the preceding 255 patients who received PG-mel.. Baseline patient characteristics were similar between the 2 groups. Post-AHCT rates of relapse were comparable in the PG-mel and PGF-mel groups. Some adverse events were observed at a higher frequency in the PG-mel group compared to the PGF-mel group (grade ≥ 2 mucositis, febrile neutropenia, other infectious complications, and acute renal insufficiency). Time to neutrophil engraftment was slightly longer in the PG-mel group while time to platelet engraftment was longer in PGF-mel group. Red cell transfusion requirement was higher with the use of PG-mel but not platelet transfusion. Duration of hospitalization was slightly shorter with PGF-mel but readmission rates within 30 days of discharge were higher.. Considering possible confounding factors could possibly account for observed differences in some adverse events, the comparable treatment responses, and difference in cost of the 2 formulation, The OSU reverted to PG-mel as the preferred formulation for HDM-AHCT in MM.

    We evaluated impact of melphalan dose on transplant outcomes for multiple myeloma. Between 1995 and 2019 459 consecutive patients received a transplant; 69(15%) received melphalan ≤150 mg/m2 (Mel 150 cohort) and 390 (85%) melphalan 200 mg/m2 (MEL 200 cohort). The primary outcome was overall survival (OS) from the date of transplant. Progression-free survival (PFS), engraftment, transplant response, and cumulative relapse at 2 years were secondary outcome measures. Patients in Mel 150 cohort had adverse clinical and laboratory parameters at base line. Transplant response was better for Mel 200 cohort (

Effects of the SLCO1B1 A388G single nucleotide polymorphism on the development, clinical parameters, treatment, and survival of multiple myeloma cases in a Polish population.
    Molecular biology reports, 2023, Volume: 50, Issue:2

    Multiple myeloma is one of the most common hematological malignancies worldwide. Genetic alterations may lead to the progression from monoclonal gammopathy to multiple myeloma. Additionally, the genetic background of the disease might influence therapy outcomes, including survival time. SLCO1B1, belonging to the OATPs family, is a membrane protein that mediates the uptake of a wide range of endogenous and exogenous (including drugs) compounds.. In this study, the A388G single nucleotide polymorphism in the SLCO1B1 gene in Polish multiple myeloma patients was determined. This polymorphism affects the amino acid change of the protein, so it may be responsible for treatment effectiveness or risk of disease development. A388G was evaluated by the PCR-RFLP method. The presented study showed a statistically significant association between the GG genotype with longer survival of patients with multiple myeloma with Melphalan-Prednisone therapy compared to other treatment regimens (p = 0.0271). There was no statistically significant association in the frequency of genotypes (p = 0.8211) and alleles: allele A (p = 0.5442); allele G (p = 0.8020) between multiple myeloma patients and a control group.. The A388G polymorphism does not seem to affect the increased risk of the development of multiple myeloma. However, the occurrence of the GG genotype may prolong of patients overall survival in the case of Melphalan-Prednisone therapy.

High-dose melphalan treatment significantly increases mutational burden at relapse in multiple myeloma.
    Blood, 2023, 04-06, Volume: 141, Issue:14

    High-dose melphalan (HDM) improves progression-free survival in multiple myeloma (MM), yet melphalan is a DNA-damaging alkylating agent; therefore, we assessed its mutational effect on surviving myeloma cells by analyzing paired MM samples collected at diagnosis and relapse in the IFM 2009 study. We performed deep whole-genome sequencing on samples from 68 patients, 43 of whom were treated with RVD (lenalidomide, bortezomib, and dexamethasone) and 25 with RVD + HDM. Although the number of mutations was similar at diagnosis in both groups (7137 vs 7230; P = .67), the HDM group had significantly more mutations at relapse (9242 vs 13 383, P = .005). No change in the frequency of copy number alterations or structural variants was observed. The newly acquired mutations were typically associated with DNA damage and double-stranded breaks and were predominantly on the transcribed strand. A machine learning model, using this unique pattern, predicted patients who would receive HDM with high sensitivity, specificity, and positive prediction value. Clonal evolution analysis showed that all patients treated with HDM had clonal selection, whereas a static progression was observed with RVD. A significantly higher percentage of mutations were subclonal in the HDM cohort. Intriguingly, patients treated with HDM who achieved complete remission (CR) had significantly more mutations at relapse yet had similar survival rates as those treated with RVD who achieved CR. This similarity could have been due to HDM relapse samples having significantly more neoantigens. Overall, our study identifies increased genomic changes associated with HDM and provides rationale to further understand clonal complexity.

Autologous stem cell transplantation in multiple myeloma patients with renal impairment.
    Annals of hematology, 2023, Volume: 102, Issue:3

    Renal impairment (RI) used to exclude multiple myeloma (MM) patients from autologous stem cell transplantation (ASCT) for safety concerns. Here, we retrospectively reviewed 34 consecutively transplanted patients with creatinine clearance < 60 ml/min at ASCT in recent 5 years at our institution. Busulfan/cyclophosphamide and high-dose melphalan were both employed as conditioning regimens. We found 62% grade 1-2 oral mucositis, 12% grade 3 oral mucositis, 48% grade 3 infection, 8% grade ≥ 4 infection, 50% grade 1 transient creatinine increase, 15% cardiac adverse events, and 12% engraftment syndrome. One case of secondary platelet graft failure and 1 case of transplantation-related mortality were observed. Interleukin-6 concentration was elevated among patients with increased body temperature and/or N-terminal pro-brain natriuretic peptide during engraftment, and close monitoring of these markers may help to predict susceptibility to cardiac events and engraftment syndrome. Adverse events occurred frequently, but the majority were manageable in this cohort. ASCT would further deepen the anti-myeloma efficacy and slightly ameliorated renal function. With a median follow-up of 26.2 months post transplantation (range: 1.6-74.8 months), the median progression-free survival (PFS) and overall survival (OS) post-transplantation of patients undergoing first-line transplantation were not reached; the median PFS post-transplantation of patients undergoing rescue transplantation was 19.2 months and the median OS was not reached.

Impact of second primary malignancy post-autologous transplantation on outcomes of multiple myeloma: a CIBMTR analysis.
    Blood advances, 2023, 06-27, Volume: 7, Issue:12

    The overall survival (OS) has improved significantly in multiple myeloma (MM) over the last decade with the use of proteasome inhibitor and immunomodulatory drug-based combinations, followed by high-dose melphalan and autologous hematopoietic stem cell transplantation (auto-HSCT) and subsequent maintenance therapies in eligible newly diagnosed patients. However, clinical trials using auto-HSCT followed by lenalidomide maintenance have shown an increased risk of second primary malignancies (SPM), including second hematological malignancies (SHM). We evaluated the impact of SPM and SHM on progression-free survival (PFS) and OS in patients with MM after auto-HSCT using CIBMTR registry data. Adult patients with MM who underwent first auto-HSCT in the United States with melphalan conditioning regimen from 2011 to 2018 and received maintenance therapy were included (n = 3948). At a median follow-up of 37 months, 175 (4%) patients developed SPM, including 112 (64%) solid, 36 (20%) myeloid, 24 (14%) SHM, not otherwise specified, and 3 (2%) lymphoid malignancies. Multivariate analysis demonstrated that SPM and SHM were associated with an inferior PFS (hazard ratio [HR] 2.62, P < .001 and HR 5.01, P < .001, respectively) and OS (HR 3.85, P < .001 and HR 8.13, P < .001, respectively). In patients who developed SPM and SHM, MM remained the most frequent primary cause of death (42% vs 30% and 53% vs 18%, respectively). We conclude the development of SPM and SHM leads to a poor survival in patients with MM and is an important survivorship challenge. Given the median survival for MM continues to improve, continued vigilance is needed to assess the risks of SPM and SHM with maintenance therapy post-auto-HSCT.

    Haematologica, 2023, 08-01, Volume: 108, Issue:8

    Multiple Myeloma (MM) is an incurable plasma cell malignancy often treated by autologous stem cell transplant (ASCT). Clinical response to ASCT has been associated with DNA repair efficiency. Here we interrogated the role of the base excision DNA repair (BER) pathway in MM response to ASCT. Across 450 clinical samples and six disease stages, expression levels of genes in the BER pathway were found to be highly upregulated during the development of MM. In a separate cohort of 559 patients with MM treated with ASCT, expression of BER pathway members MPG and PARP3 was positively associated with overall survival (OS) while expression of PARP1, POLD1, and POLD2 was negatively associated with OS. In a validation cohort of 356 patients with MM treated with ASCT, PARP1 and POLD2 findings were replicated. In patients with MM who never received ASCT (n=319), PARP1 and POLD2 were not associated with OS, suggesting that the prognostic effect of these genes may be treatment-dependent. In preclinical models of MM, synergy was observed in anti-tumor activity when poly (ADPribose) polymerase (PARP) inhibitors (olaparib, talazoparib) were used in combination with melphalan. The negative prognosis associated with PARP1 and POLD2 expression along with the apparent melphalan-sensitizing effect of PARP inhibition may suggest this pathway as a potential biomarker in patients with MM in the setting of ASCT. Further understanding of the role of the BER pathway in MM is vital to improve therapeutic strategies related to ASCT.

A rapid intracellular enrichment of alkylating payload is essential for melphalan flufenamide potency and mechanism of action.
    Biochemical and biophysical research communications, 2023, 05-14, Volume: 656

    Despite decades of development of treatments and the successful application of targeted therapies for multiple myeloma, clinical challenges remain for patients with relapsed/refractory disease. A drug designed for efficient delivery of an alkylating payload into tumor cells that yields a favorable therapeutic window can be an attractive choice. Herein we describe melphalan flufenamide (melflufen), a drug with a peptide carrier component conjugated to an alkylating payload, and its cellular metabolism. We further underline the fundamental role of enzymatic hydrolysis in the rapid and robust accumulation of alkylating metabolites in cancer cells and their importance for downstream effects. The formed alkylating metabolites were shown to cause DNA damage, both on purified DNA and on chromatin in cells, with both nuclear and mitochondrial DNA affected in the latter. Furthermore, the rapid intracellular enrichment of alkylating metabolites is shown to be essential for the rapid kinetics of the downstream intracellular effects such as DNA damage signaling and induction of apoptosis. To evaluate the importance of enzymatic hydrolysis for melflufen's efficacy, all four stereoisomers of the compound were studied in a systematic approach and shown to have a different pattern of metabolism. In comparison with melflufen, stereoisomers lacking intracellular accumulation of alkylating payloads showed cytotoxic activity only at significantly higher concentration, slower DNA damage kinetics, and different mechanisms of action to reach cellular apoptosis.

Cyclical 10-day dosing of melphalan for canine multiple myeloma.
    Veterinary and comparative oncology, 2023, Volume: 21, Issue:3

    Canine multiple myeloma (MM) is typically treated with melphalan chemotherapy. A protocol with repeated 10-day cyclical dosing of melphalan has been used at our institution but has not been described in the literature. Our objectives were to describe the outcome and adverse events of this protocol in a retrospective case series. We hypothesised the cyclical 10-day protocol would have similar outcomes compared to other reported chemotherapy protocols. Dogs diagnosed with MM that received melphalan treatment at Cornell University Hospital for Animals were identified through a database search. Records were retrospectively reviewed. Seventeen dogs met inclusion criteria. Lethargy was the most common presenting complaint. The median duration of clinical signs was 53 days (range, 2-150 days). Seventeen dogs had hyperglobulinemia with 16/17 having monoclonal gammopathies. Sixteen dogs had bone marrow aspiration and cytology performed at initial diagnosis and plasmacytosis was diagnosed in all. Based on serum globulin concentrations, 10 of 17 dogs (59%) achieved complete response (CR), and 3 dogs (18%) achieved partial response (PR), for an overall response rate of 76%. The median overall survival time was 512 days (range, 39-1065). Retinal detachment (n = 3) and maximum response of CR/PR (n = 13) were associated with overall survival on multivariate analysis (p = .045 and .046, respectively). Adverse events were minimal with diarrhoea being the most reported (n = 6). This cyclical 10-day protocol was better-tolerated with fewer adverse events than with other reported chemotherapy protocols, but response rate was also lower, likely due to a lower dosing intensity.

Melphalan Febrile Neutropenia Risk Factors.
    Gan to kagaku ryoho. Cancer & chemotherapy, 2023, Volume: 50, Issue:6

    This study aimed to identify the risk factors of febrile neutropenia(FN)onset associated with melphalan(L-PAM)therapy. Thirty-nine patients(21 men, 18 women)were administered L-PAM intravenously for multiple myeloma(MM)from April 2011 to February 2022 at the Department of Hematology of Gifu Municipal Hospital. Patients were classified into those with and without FN(Grade 3 or higher), complete blood count and liver function tests were performed immediately before starting therapy. Univariate analysis with Fisher's exact probability test was performed. Factors with p<0.2 were considered as independent variables for multivariate analysis in the multiple logistic regression analysis. A multivariate analysis with 2 independent variables, lactate dehydrogenase(LD)level>222 U/L(upper limit of the facility reference value)and white <3.3×103/μL(lower limit of the facility reference value)from the univariate analysis, and FN onset(Grade 3 or higher)as the dependent variable showed that LD level>222 U/L(odds ratio: 6.33, 95% confidence interval: 1.12-35.8, p=0.037)was a significant factor. In conclusion, patients with LD levels >222 U/L immediately before starting therapy require adequate monitoring for FN onset following L-PAM administration.

Benefit Versus Risk Assessment of Melflufen and Dexamethasone in Relapsed/Refractory Multiple Myeloma: Analyses From Longer Follow-up of the OCEAN and HORIZON Studies.
    Clinical lymphoma, myeloma & leukemia, 2023, Volume: 23, Issue:9

    Melphalan flufenamide (melflufen), a first-in-class alkylating peptide-drug conjugate, plus dexamethasone demonstrated superior progression-free survival (PFS) but directionally different overall survival (OS) favoring pomalidomide (hazard ratio [HR], 1.10) in OCEAN.. These analyses further investigated prognostic subgroups impacting survival in updated data from the randomized, phase 3 OCEAN study (NCT03151811; date: February 3, 2022) and the phase 2 HORIZON study (NCT02963493; date: February 2, 2022).. In OCEAN, subgroups prognostic for OS were age (P = .011; <65 years favored pomalidomide) and no previous autologous stem cell transplant (ASCT) or progression >36 months after ASCT (P = .001; favored melflufen). Overall, 245 of 495 (49%) patients randomized had received a previous ASCT, of which 202 (82%) had progressed within 36 months following their ASCT. When excluding patients who had progressed <36 months post-ASCT (melflufen group, n = 145; pomalidomide group, n = 148), median OS was 23.6 months with melflufen and 19.8 months with pomalidomide (HR, 0.83 [95% CI, 0.62-1.12]; P = .22). Among patients with triple-class refractory disease in HORIZON, patients who had progressed <36 months post-ASCT (n = 58) had a lower response rate and shorter duration of response and PFS than the remaining patients (n = 52). Safety was consistent with previous reports.. These analyses demonstrate a consistent benefit for melflufen and dexamethasone in patients with relapsed/refractory multiple myeloma who have not received an ASCT or progressed >36 months after receiving an ASCT (ClinicalTrials.gov identifier: NCT03151811).

Effectiveness, Safety, and Cost Implications of Outpatient Autologous Hematopoietic Stem Cell Transplant for Multiple Myeloma.
    Hematology/oncology and stem cell therapy, 2023, May-23, Volume: 16, Issue:4

    Autologous hematopoietic stem cell transplant (aHCT) has become standard care for patients with multiple myeloma (MM). Outpatient aHCT with high-dose melphalan conditioning has reduced costs and length of hospital stay. This study aimed to highlight the effectiveness, safety, and cost implications of outpatient vs inpatient aHCT at a tertiary academic medical center, as well as the utility of growth factor use in these patients.. Using an institutional HCT database, a total of 100 patients undergoing aHCT for MM were identified; 50 patients who underwent aHCT in the outpatient setting (chemotherapy and stem cell infusion followed by inpatient admission if needed) were compared with 50 patients in the inpatient setting (chemotherapy and stem cell infusion followed by discharge to outpatient setting). Patients were excluded if the melphalan dose was less than 200 mg/m. Time to neutrophil and platelet engraftment was shorter in the outpatient group than in the inpatient group (14 vs 16 days and 19 vs 21 days, respectively; P < 0.001). Median length of hospital stay was also shorter in the outpatient group (8.5 vs 15.5 days, respectively; P < 0.001). Ninety percent of the outpatient group required admission for neutropenic fever, and 60% of these patients received growth factor support starting at a median of 9 days after stem cell infusion, for a median duration of 4 days. Compared to 16 patients who did not receive growth factor support, these patients had a significantly shorter time to neutrophil recovery (13 days with vs 15 days without growth factor, P = 0.02) and no difference in the total length of hospital stay (8 days with vs 10 days without growth factor, P = 0.43).. For adult patients with MM undergoing aHCT, the outpatient setting is safe and reduces the total length of hospital stay and thus overall transplant costs. Growth factor support for patients with febrile neutropenia may not reduce length of stay for subsequent hospitalizations.

Post-Autologous Hematopoietic Cell Transplant Care in the "Home Sweet Home" Setting: A Treatment Paradigm Shift.
    Hematology/oncology and stem cell therapy, 2023, May-23, Volume: 16, Issue:4

    Multiple myeloma (MM) is the second most common hematologic malignancy, with 34,470 estimated new cases in 2022. High-dose therapy followed by autologous hematopoietic cell transplantation (auto-HCT) remains a standard treatment for MM even in the era of novel therapies. This is usually performed in hospital-based settings, either in the inpatient or outpatient units. Advanced Care at Home (ACH) represents a virtual hybrid hospital-at-home program that combines a virtual provider-staffed command center with a vendor-mediated supply chain capable of delivering high-acuity care in the comfort of the patients' own homes. In our program, we used the existing ACH platform to deliver post-HCT care for recipients of auto-HCT.. Patients were discharged to their homes after completing the infusion on day 0 or day +1 at the latest. Post-infusion care was provided by the ACH team in coordination with the BMT team. The median time intervals to absolute neutrophil count and platelet engraftment were 12 (range, 11-13) and 11 (range, 9-16) days, respectively. All patients were successfully discharged from the ACH program at a median of day +14 (range, day +14 to day +15).. Our results highlight the feasibility of delivering post-HCT care for auto-HCT recipients in the home setting and confirm the generalizability of this approach.

Busulfan plus melphalan versus high-dose melphalan as a conditioning regimen for autologous stem cell transplantation in multiple myeloma with high-risk features (KMM 2015).
    Annals of hematology, 2023, Volume: 102, Issue:8

    Despite the development of effective agents for multiple myeloma (MM), the management of patients with high-risk MM (HRMM) is challenging. High-dose treatment followed by autologous stem cell transplantation (ASCT) is regarded as upfront treatment for transplant-eligible patients with HRMM. In the present study, we retrospectively investigated the efficacies of two conditioning regimens for upfront ASCT in newly diagnosed patients with MM and high-risk features: high-dose melphalan (HDMEL; 200 mg/m

Comparisons of efficacy between frontline treatment with bortezomib-melphalan-prednisone and lenalidomide-dexamethasone for transplant-ineligible multiple myeloma: a multicenter real-world based registry report, CAREMM-2102 study.
    Journal of cancer research and clinical oncology, 2023, Volume: 149, Issue:13

    Bortezomib-melphalan-prednisone (VMP) and lenalidomide-dexamethasone (Rd) remain the standard treatments for transplant-ineligible patients with newly diagnosed multiple myeloma (NDMM). This study aimed to compare real-world benefits between the two regimens. We also were interested in exploring efficacy according to subsequent therapy following VMP or Rd.. A total of 559 NDMM patients treated with VMP (n = 443, 79.2%) or Rd (n = 116, 20.8%) was recruited retrospectively from a multicenter database.. Rd provided more benefits than VMP-overall response rate: 92.2 vs. 81.8%, p = 0.018; median progression-free survival (PFS): 20.0 vs. 14.5 months, p <0.001; second PFS (PFS2): 43.9 vs. 36.9 months, p = 0.012; overall survival (OS): 100.1 vs. 85.0 months, p = 0.017. Multivariable analysis revealed significant benefits of Rd over VMP, with hazard ratios of 0.722, 0.627, and 0.586 for PFS, PFS2, and OS, respectively. In propensity score-matched cohorts with matched VMP (n = 201) and Rd (n = 67) arms to balance baseline characteristics, Rd still showed significantly better outcomes for PFS, PFS2, and OS than VMP. Following VMP failure, triplet therapy showed significant benefits for response and PFS2; after Rd failure, PFS2 with carfilzomib-dexamethasone was significantly better than bortezomib-based doublet treatment.. These real-world findings may assist with better selection between VMP and Rd as well as subsequent therapy for NDMM.

The salivary proteome in relation to oral mucositis in autologous hematopoietic stem cell transplantation recipients: a labelled and label-free proteomics approach.
    BMC oral health, 2023, 07-07, Volume: 23, Issue:1

    Oral mucositis is a frequently seen complication in the first weeks after hematopoietic stem cell transplantation recipients which can severely affects patients quality of life. In this study, a labelled and label-free proteomics approach were used to identify differences between the salivary proteomes of autologous hematopoietic stem cell transplantation (ASCT) recipients developing ulcerative oral mucositis (ULC-OM; WHO score ≥ 2) or not (NON-OM).. In the TMT-labelled analysis we pooled saliva samples from 5 ULC-OM patients at each of 5 timepoints: baseline, 1, 2, 3 weeks and 3 months after ASCT and compared these with pooled samples from 5 NON-OM patients. For the label-free analysis we analyzed saliva samples from 9 ULC-OM and 10 NON-OM patients at 6 different timepoints (including 12 months after ASCT) with Data-Independent Acquisition (DIA). As spectral library, all samples were grouped (ULC-OM vs NON-OM) and analyzed with Data Dependent Analysis (DDA). PCA plots and a volcano plot were generated in RStudio and differently regulated proteins were analyzed using GO analysis with g:Profiler.. A different clustering of ULC-OM pools was found at baseline, weeks 2 and 3 after ASCT with TMT-labelled analysis. Using label-free analysis, week 1-3 samples clustered distinctly from the other timepoints. Unique and up-regulated proteins in the NON-OM group (DDA analysis) were involved in immune system-related processes, while those proteins in the ULC-OM group were intracellular proteins indicating cell lysis.. The salivary proteome in ASCT recipients has a tissue protective or tissue-damage signature, that corresponded with the absence or presence of ulcerative oral mucositis, respectively.. The study is registered in the national trial register (NTR5760; automatically added to the International Clinical Trial Registry Platform).

A Single Nucleotide Polymorphism (SNP) in the
    Anticancer research, 2022, Volume: 42, Issue:1

    It has been reported that expression of OCT3 enhanced the sensitivity to melphalan in cells, indicative of potential roles of OCT3 in melphalan transport. Herein we investigated the association of select single nucleotide polymorphisms in SLC22A3 (gene encoding OCT3) with clinical outcomes in multiple myeloma (MM) patients with hematopoietic autologous stem cell transplants followed by high-dose melphalan therapy.. Melphlan concentrations in blood samples from 108 MM patients were measured using liquid chromatography-tandem mass spectrometry (LC-MS/ΜS); genotypes of rs2048327, rs1810126, and rs3088442 in these patients were determined using quatitive RT-PCR assays.. Rs3088442 A variant-carriers had a significantly increased risk of severe oral mucositis in comparison with homozygous rs3088442 G-carriers with adjusted odds ratio of 4.00 (95% CI=1.25-14.7; p=0.027). Rs3088442 A carriers tended to have lower creatinine clearance (p=0.10) and higher maximum plasma concentration of melphalan (p=0.07).. OCT3 might be involved in melphalan transport in MM patients.

The emerging importance and evolving understanding of clonal hematopoiesis in multiple myeloma.
    Seminars in oncology, 2022, Volume: 49, Issue:1

    Multiple myeloma (MM) is the second most common hematologic malignancy diagnosed in the United States. With a growing arsenal of novel therapies, patients are living longer and hence are at increased risk of secondary cancers such as myelodysplastic syndrome (MDS) and acute myeloid leukemia (AML). While MDS-associated cytogenetic abnormalities have been described in patients with a diagnosis of for decades, clonal hematopoiesis (CH) has been described only recently. CH has been shown to correlate with inferior survival in MM due to increased risk of disease progression in patients who are treated with high-dose melphalan without lenalidomide maintenance. When involving specific high-risk genes, multiple genes, or when present at high variant allelic frequencies, CH could also potentially elevate the risk of secondary MDS and/or AML, cardiovascular events, and venous thromboembolic events. Despite growing knowledge about CH in patients with MM, many questions remain unanswered. Further studies are needed to better understand the prognostic and therapeutic significance of CH in MM and its precursor conditions, as well as the effect of specific treatments on long-term outcome.

Extramedullary plasmacytoma with colonic involvement: experience in a tertiary hospital.
    Revista espanola de enfermedades digestivas, 2022, Volume: 114, Issue:10

    A 71-year-old woman diagnosed with type II diabetes mellitus with severe iron deficiency anemia and positive fecal occult blood. Colonoscopy was performed, showing a soft mass in the ascending colon, with biopsies compatible with plasmacytoma and restriction for Kappa light chains. After bone marrow aspiration, associated IgG multiple myeloma was detected, so chemotherapy with VMP (bortezomib, melphalan and prednisone) was started. Colonoscopy six months later showed that the ulcerated lesion had a reduction in tumor size of up to 80%. A 27-year-old male with a history of kidney transplantation and symptoms of chronic diarrhea, colonoscopy was indicated with the finding of a large exophytic and ulcerated lesion in the cecum. Pathology revealed plasmacytoma with restriction of lambda light chains. After ruling out lesions in other locations, the patient was treated with immunochemotherapy according to the Bortezomib-Rituximab-Dexamethasone scheme, with subsequent complete clinical and endoscopic remission. Plasmacytoma accounts for < 4 % of plasma cell tumours. It may appear isolated or associated with another plasma cell neoplasm, mainly multiple myeloma. Its presence in the gastrointestinal tract is rare, being infrequent in the stomach or small intestine, and even rarer in the colonic tract (incidence 1/10,000,000). The clinical manifestations are similar to those of other colon neoplasms, while the treatment or prognosis may differ from those of other neoplasms. In patients with clinical suspicion, it is important to perform an early endoscopic study, especially in patients diagnosed with multiple myeloma.

Growth Response and Differentiation of Bone Marrow-Derived Mesenchymal Stem/Stromal Cells in the Presence of Novel Multiple Myeloma Drug Melflufen.
    Cells, 2022, 05-07, Volume: 11, Issue:9

    Mesenchymal stem/stromal cells (MSCs) are self-renewing and multipotent progenitors, which constitute the main cellular compartment of the bone marrow stroma. Because MSCs have an important role in the pathogenesis of multiple myeloma, it is essential to know if novel drugs target MSCs. Melflufen is a novel anticancer peptide-drug conjugate compound for patients with relapsed refractory multiple myeloma. Here, we studied the cytotoxicity of melflufen, melphalan and doxorubicin in healthy human bone marrow-derived MSCs (BMSCs) and how these drugs affect BMSC proliferation. We established co-cultures of BMSCs with MM.1S myeloma cells to see if BMSCs increase or decrease the cytotoxicity of melflufen, melphalan, bortezomib and doxorubicin. We evaluated how the drugs affect BMSC differentiation into adipocytes and osteoblasts and the BMSC-supported formation of vascular networks. Our results showed that BMSCs were more sensitive to melflufen than to melphalan. The cytotoxicity of melflufen in myeloma cells was not affected by the co-culture with BMSCs, as was the case for melphalan, bortezomib and doxorubicin. Adipogenesis, osteogenesis and BMSC-mediated angiogenesis were all affected by melflufen. Melphalan and doxorubicin affected BMSC differentiation in similar ways. The effects on adipogenesis and osteogenesis were not solely because of effects on proliferation, seen from the differential expression of differentiation markers normalized by cell number. Overall, our results indicate that melflufen has a significant impact on BMSCs, which could possibly affect therapy outcome.

Multiple Myeloma: Impact of Time to Transplant on the Outcome.
    Clinical lymphoma, myeloma & leukemia, 2022, Volume: 22, Issue:9

    Autologous stem cell transplant (ASCT) is a standard therapy for transplant eligible patients of multiple myeloma (MM). To evaluate impact of time to transplant on subsequent outcomes, we analyzed data on consecutive MM patients who received novel agents-based induction prior to transplant.. Between 2006 and 2019, 363 MM patients underwent ASCT. Patients' median age was 52 years, ranging from 20 to 72 years, 233 (64.2%) were males. Median interval from diagnosis to transplant was 11.5 months (range, 4-67.5); 201 (55.4%) patients underwent ASCT within 12 months (early) and 162 (44.6%) beyond 12 months since diagnosis (delayed ASCT). Primary objective was progression-free survival. Secondary objectives were-response rate to transplant, overall survival (OS), and transplant-related mortality (TRM).. Post-ASCT complete response (CR) (77.1% vs. 64.8%; P < .025) and CR+ very good partial response rate (89% vs. 81.5%; P < .03) was higher for early ASCT cohort. Engraftment characteristics, regimen-related toxicities, and day +100 TRM (3.5% vs 3.7%; P = .564) were similar in 2 cohorts. Median OS for early versus late cohort from date of diagnosis is 127.0 (95% CI, 98.9-155.1) versus 104.5 months (95% CI, 79.3-129.6; P = .356) and from date of transplant is 119.0 (95% CI, 93.4-144.6) versus 89.5 months (95% CI, 57.4-121.6), P < .02. Median PFS is better for early transplant cohort; 69.5 (95% CI, 56.7-82.3) versus 50.0 months (95% CI, 35.6-64.4), P < .05, respectively.. Early transplant for myeloma is associated with higher response rate and better progression-free survival.

Cryopreserved versus non-cryopreserved stem cell autografts in multiple myeloma a restrospective cohort study.
    Bone marrow transplantation, 2022, Volume: 57, Issue:8

    The use of non-cryopreserved hematopoietic stem cells (HSC) can be an alternative to the traditional cryopreserved infusions of HSCs in autologous stem cell transplantation (aHSCT). After high-dose melphalan conditioning (HDM), we sought to compare time to engraftment, overall survival, and safety in multiple myeloma (MM) patients undergoing a first aHSCT after high-dose melphalan conditioning (HDM). We conducted a cohort study from March 2018 to December 2019. Of all autologous transplants performed during this period, 105 were for MM as the first consolidation. Fifty-one patients received a cryopreserved graft; the remaining 54 patients received a fresh infusion. General clinical characteristics were similar between these two groups. Cell viability was higher in non-cryopreserved grafts (95% vs. 86% p < 0.01). Four deaths occurred during hospitalization in the cryopreserved group, one in the non-cryopreserved group. The cumulative incidence of neutrophil and platelet engraftment on D + 25 was higher in the non-cryopreserved compared to the cryopreserved group (98% vs 90% p < 0.01 and 96.2% vs 72.54% p < 0.01 respectively). Additionally, the hospital length of stay was reduced by 4 days for patients for the non-cryopreserved cohort. In summary, the use of non-cryopreserved HSCs after HDM is safe and effective compared to patients who received a cryopreserved graft.

Multiple-day administration of fosaprepitant combined with tropisetron and olanzapine improves the prevention of nausea and vomiting in patients receiving chemotherapy prior to autologous hematopoietic stem cell transplant: a retrospective study.
    Annals of hematology, 2022, Volume: 101, Issue:8

    Chemotherapy-induced nausea and vomiting (CINV) is common in patients with lymphoma and multiple myeloma (MM) receiving high-dose chemotherapy (HDC) followed by autologous stem cell transplantation (ASCT). Despite a standard triple antiemetic regimen of a neurokinin-1 (NK1) receptor antagonist (RA), a 5-hydroxytryptamine-3 (5-HT3) RA, and dexamethasone is recommended, how to control the protracted CINV in ASCT setting remains an intractable problem. Here, we retrospectively analyze CINV data of 100 patients who received either SEAM (semustine, etoposide, cytarabine, melphalan) or MEL140-200 (high-dose melphalan) before ASCT, evaluate the efficacy and safety of multiple-day administration of fosaprepitant combined with tropisetron and olanzapine (FTO), and compare the results to those of patients who received a standard regimen of aprepitant, tropisetron, and dexamethasone (ATD). The overall rate of complete response (CR), defined as no emesis and no rescue therapy, is 70% in the FTO group compared to 36% in the ATD group. Although CR rates are comparable in the acute phase between the two groups, significantly more patients treated by FTO achieve CR in the delayed phase than those treated by ATD (74% vs. 38%, p < 0.001). Moreover, FTO treatment significantly reduced the percentage of patients who are unable to eat, as well as the requirement for rescue medications. Both regimens are well tolerated and most adverse events (AEs) were generally mild and transient. In conclusion, the antiemetic strategy containing multiple-day administration of fosaprepitant is safe and effective for preventing CINV in lymphoma and MM patients, particularly in the delayed phase.

Melflufen for the treatment of multiple myeloma.
    Expert review of clinical pharmacology, 2022, Volume: 15, Issue:4

    Melphalan flufenamide (melflufen) is a first-in-class peptide-drug conjugate that takes advantage of increased aminopeptidase activity inside tumor cells to rapidly release alkylating agents therein. Melflufen in combination with dexamethasone has been evaluated in multiple clinical trials in patients with relapsed/refractory multiple myeloma (MM).. This profile covers the unique mechanism of action of melflufen, the preclinical results supporting its activity in cellular models of resistance to chemotherapy, its activity in animal models of MM, and the clinical pharmacokinetics of melflufen. Findings from clinical trials evaluating melflufen, including the pivotal phase II HORIZON study and the phase III OCEAN study, are discussed.. Although MM treatment has improved, patients with disease refractory to multiple standard-of-care drug classes face a dismal prognosis. Melflufen demonstrated efficacy and tolerability in select populations, with an initial approval in the United States in patients with ≥ four previous lines of therapy and triple-class-refractory MM. Results from the phase III OCEAN study - currently under discussion with regulatory agencies in the United States and Europe - are more complex and have been put into context herein. Lastly, melflufen provides a proof-of-concept for the utility of the peptide-drug conjugate platform in relapsed/refractory MM.

Secondary B-cell acute lymphoblastic leukaemia in a patient with multiple myeloma.
    BMJ case reports, 2022, Jun-22, Volume: 15, Issue:6

    Although patients with multiple myeloma (MM) have improved survival with current therapies, there remains a long-term risk of treatment-associated second primary malignancies. We present a case of a patient with IgG kappa MM undergoing treatment for relapsed disease who was noted to have progressive pancytopenia. For his MM, he had previously undergone autologous stem cell transplant with high-dose melphalan and had received immunomodulatory (IMiD) agents in induction, maintenance and relapse regimens. A peripheral blood smear showed abnormal lymphoid cells, and a bone marrow biopsy revealed B-cell acute lymphoblastic leukaemia (B-ALL). He underwent intensive induction chemotherapy with plans for possible allogeneic stem cell transplant. Secondary B-ALL is a rare occurrence in patients with MM, with exposure to alkylating and IMiD agents being potential risk factors.

    Clinical lymphoma, myeloma & leukemia, 2022, Volume: 22, Issue:11

    Peripheral neuropathy is a common treatment-emergent side effect during the treatment of newly diagnosed multiple myeloma. Although bortezomib is most commonly implicated, real-world data suggest that lenalidomide and dexamethasone (VRd) and autologous stem cell transplantation (ASCT) may also contribute to neuropathy and health-related quality of life (HRQoL).. The Multiple Myeloma Research Foundation (MMRF) CoMMpass Registry was queried for all patients who received frontline VRd or bortezomib, cyclophosphamide and dexamethasone (VCd). Incidence of neuropathy and patient-reported HRQoL outcomes over the first 12 months after diagnosis were compared between patients receiving VRd or VCd with or without early ASCT before 6 months.. There were 368 and 191 patients treated with VRd and VCd, respectively. VRd with early ASCT was associated with worse grade 1 neuropathy compared to VRd without early ASCT, as well as compared to VCd with early ASCT. There were no differences in neuropathy between VRd and VCd without early ASCT, and no differences in grade ≥2 neuropathy. There were significant improvements in HRQoL between baseline and 12 months in both VRd and VCd cohorts, regardless of early ASCT. Development of neuropathy was not associated with decrements in progression-free survival or overall survival.. In this longitudinal database analysis, there were no differences in grade ≥2 neuropathy between VRd and VCd frontline induction, and overall HRQoL significantly improved across all cohorts. However, differences in grade 1 neuropathy between VRd and VCd induction suggest that lenalidomide and high-dose melphalan may augment the risk of neuropathy in newly diagnosed multiple myeloma.

A prospective study of dysgeusia and related symptoms in patients with multiple myeloma after autologous hematopoietic cell transplantation.
    Cancer, 2022, 11-01, Volume: 128, Issue:21

    Dysgeusia is a common but understudied complication in patients undergoing autologous hematopoietic cell transplantation (auto-HCT). We assessed the feasibility of using chemical gustometry (CG) to measure dysgeusia and explored its associations with symptom burden, nutrition, chemotherapy pharmacokinetics (PK), and the oral microbiome.. We conducted a single-center, prospective feasibility study (NCT03276481) of patients with multiple myeloma undergoing auto-HCT. CG was performed longitudinally testing five flavors (sweet, sour, salty, bitter, umami) to calculate a total taste score (maximum score, 30). We measured caloric intake and patient-reported symptoms, assessing their correlation with oral microbiota composition and salivary and blood melphalan PK exposure.. Among all 45 patients, 39 (87%) completed at least four (>60%) and 22 (49%) completed all six CG assessments. Median total CG scores remained stable over time but were lowest at day +7 (27, range 24-30) with recovery by day +100. Symptom burden was highest by day +10 (area under the curve, 2.9; range, 1.0-4.6) corresponding with the lowest median overall caloric intake (1624 kcal; range, 1345-2267). Higher serum/salivary melphalan levels correlated with higher patient-reported dysgeusia and lower caloric intake. Oral microbiota α-diversity was stable early and increased slightly by day +100.. Assessment of dysgeusia by CG is feasible after auto-HCT. Most dysgeusia, symptom burden, and lowest caloric intake occurred during the blood count nadir. Higher melphalan concentrations correlated with more dysgeusia and poorer caloric intake. Future studies will aim to modulate melphalan exposure by PK-targeted dosing and characterize patient taste preferences to personalize diets for improved nutritional intake.. Taste changes after cancer treatments are very common. We used chemical gustometry (taste testing) to study taste changes and to better understand why patients with multiple myeloma experience this symptom after autologous hematopoietic cell transplantation. We found that taste testing was feasible, taste changes peaked when blood counts were lowest, and most patients recovered their taste by 100 days after transplantation. Taste changes correlated with lower food intake and with higher levels of chemotherapy in the body. Future work will focus on using personalized chemotherapy doses to reduce taste changes and to match patients' individual taste preferences with their diets.

Conditioning with melphalan 200 mg/m
    European journal of haematology, 2022, Volume: 109, Issue:6

    Despite the effectiveness of newer drugs for the treatment of multiple myeloma (MM), the outcomes are further improved by subsequent autologous stem cell transplantation (ASCT). Data on effectiveness in older patients are limited. We compared outcomes in patients aged 65-75 years depending on whether they were treated with ASCT or not and compared those to outcomes in patients <65 years.. This was a retrospective, single-center study. We compared progression-free survival (PFS) and overall survival (OS) for all MM patients below and above the age of 65 years treated ± ASCT at the Karolinska University Hospital between 2010 and 2020. PFS and OS were calculated by the Kaplan-Meier method. Variables affecting PFS and OS were evaluated using Cox regression model.. Both PFS and OS were improved in the group 65-75 years treated +ASCT compared to those treated pharmacologically (p = 0.008 and p < 0.001, respectively). There were no significant differences between patients <65 years and those 65-75 years treated with ASCT.. The findings indicate that even patients >65 years should be evaluated as candidates for ASCT. An individualized approach supported by a frailty/geriatric assessment score could assist clinicians to select the appropriate treatment for each patient.

Spurious laboratory results associated with immunoglobulin M gammopathy in a dog with multiple myeloma.
    Journal of veterinary internal medicine, 2022, Volume: 36, Issue:6

    An 11 year old female-neutered Labrador presented for facial swelling. Clinicopathological abnormalities included hyperglobulinemia, azotemia, hypercalcemia, nonregenerative anemia, thrombocytopenia, and spurious hypoglycemia. Normoglycemia was subsequently confirmed using a cage-side analyzer (AlphaTRAK, Zoetis, UK). Serum and urine protein electrophoresis documented monoclonal (immunoglobulin M) gammopathy with Bence-Jones proteinuria. Computed tomography imaging revealed a monostotic osteolytic bone-lesion, and bone marrow cytology and histopathology documented plasmacytosis with multiple myeloma oncogene 1 / interferon regulatory factor 4 positivity, consistent with multiple myeloma. Infectious disease testing initially indicated seropositivity for Leishmania, Borrelia, and Anaplasma spp.; however, Leishmania PCR (splenic and bone marrow aspirates), and paired serological titers for Borrelia and Anaplasma were negative. Consequently, initial serological results were considered to be false positive because of paraproteinemia-associated assay interference. Chemotherapy (prednisolone and melphalan combination therapy) was initiated, but the dog was euthanased 30 days later because of the development of pericardial effusion. This is a report of spurious serological (and other laboratory) results occurring secondary to monoclonal gammopathy in a dog.

Pilot Trial of Homebound Hematopoietic Cell Transplantation.
    Transplantation and cellular therapy, 2022, Volume: 28, Issue:12

    For eligible patients with multiple myeloma (MM) and amyloid light chain (AL) amyloidosis, high-dose chemotherapy and autologous hematopoietic cell transplantation (HCT) is a standard and widely used consolidation therapy. Autologous HCT requires specialized care at a transplantation center and investment from patients and caregivers. We studied the safety and feasibility of delivering transplantation care in a homebound setting to decrease the burden of therapy and increase access to autologous HCT. Patients with MM and AL amyloidosis undergoing autologous HCT were eligible if they resided in designated ZIP codes and had a full-time caregiver, Wi-Fi connection, HCT Comorbidity Index ≤3, and Karnofsky Performance Status score ≥80. High-dose melphalan (on day -2) and hematopoietic cell reinfusion (day 0) were administered in the outpatient clinic. Protocol-specific home care was provided from day +1 through engraftment. Patients were assessed and blood was drawn daily by advanced practice providers. Interventions were delivered by registered nurses. Attending physicians communicated daily through telemedicine. Quality of life, patient and caregiver satisfaction, and fecal microbiota profiling data were collected. Fifteen patients were enrolled and received transplantation care at home starting on day +1 following hematopoietic cell infusion. Patients remained in the program for an average of 12 days and required an average of 2 outpatient visits while receiving home care. Seven of 15 patients were admitted for a median of 4 days (range, 3 to 10 days); admission occurred on day +7 in 5 patients, on day +8 in 1 patient, and on day +12 in 1 patient for neutropenic fever in 2 patients, fever attributed to engraftment syndrome in 2 patients, diarrhea in 2 patients, and dehydration in 1 patient. Only 1 patient had a documented infection (Clostridioides difficile). One patient admitted with neutropenic fever required intensive care unit admission for a gastrointestinal bleed. Forty-seven percent of the patients experienced a grade ≥3 nonhematologic toxicity. There were no deaths on the study. Patients and caregivers reported high satisfaction with care. Microbiota diversity patterns were similar to those of autologous HCT recipients who did not receive post-HCT care at home, although a subset of the cohort maintained microbiota diversity throughout. Homebound HCT in an urban setting is safe and feasible, with less than one-half of patients requiring inpatient adm

Newly Synthesized Melphalan Analogs Induce DNA Damage and Mitotic Catastrophe in Hematological Malignant Cancer Cells.
    International journal of molecular sciences, 2022, Nov-17, Volume: 23, Issue:22

    Myeloablative therapy with highdoses of the cytostatic drug melphalan (MEL) in preparation for hematopoietic cell transplantation is the standard of care for multiple myeloma (MM) patients. Melphalan is a bifunctional alkylating agent that covalently binds to nucleophilic sites in the DNA and effective in the treatment, but unfortunately has limited therapeutic benefit. Therefore, new approaches are urgently needed for patients who are resistant to existing standard treatment with MEL. Regulating the pharmacological activity of drug molecules by modifying their structure is one method for improving their effectiveness. The purpose of this work was to analyze the physicochemical and biological properties of newly synthesized melphalan derivatives (EE-MEL, EM-MEL, EM-MOR-MEL, EM-I-MEL, EM-T-MEL) obtained through the esterification of the carboxyl group and the replacement of the the amino group with an amidine group. Compounds were selected based on our previous studies for their improved anticancer properties in comparison with the original drug. For this, we first evaluated the physicochemical properties using the circular dichroism technique, then analyzed the zeta potential and the hydrodynamic diameters of the particles. Then, the in vitro biological properties of the analogs were tested on multiple myeloma (RPMI8226), acute monocytic leukemia (THP1), and promyelocytic leukemia (HL60) cells as model systems for hematological malignant cells. DNA damage was assessed by immunostaining γH2AX, cell cycle distribution changes by propidium iodide (PI) staining, and cell death by the activation of caspase 2. We proved that the newly synthesized derivatives, in particular EM-MOR-MEL and EM-T-MEL, affected the B-DNA conformation, thus increasing the DNA damage. As a result of the DNA changes, the cell cycle was arrested in the S and G2/M phases. The cell death occurred by activating a mitotic catastrophe. Our investigations suggest that the analogs EM-MOR-MEL and EM-T-MEL have better anti-cancer activity in multiple myeloma cells than the currently used melphalan.

The Combination of Panobinostat and Melphalan for the Treatment of Patients with Multiple Myeloma.
    International journal of molecular sciences, 2022, Dec-10, Volume: 23, Issue:24

    Histone deacetylase inhibitors show synergy with several genotoxic drugs. Herein, we investigated the biological impact of the combined treatment of panobinostat and melphalan in multiple myeloma (MM). DNA damage response (DDR) parameters and the expression of DDR-associated genes were analyzed in bone marrow plasma cells (BMPCs) and peripheral blood mononuclear cells (PBMCs) from 26 newly diagnosed MM patients. PBMCs from 25 healthy controls (HC) were examined in parallel. Compared with the ex vivo melphalan-only treatment, combined treatment with panobinostat and melphalan significantly reduced the efficiency of nucleotide excision repair (NER) and double-strand-break repair (DSB/R), enhanced the accumulation of DNA lesions (monoadducts and DSBs), and increased the apoptosis rate only in patients’ BMPCs (all p < 0.001); marginal changes were observed in PBMCs from the same patients or HC. Accordingly, panobinostat pre-treatment decreased the expression levels of critical NER (DDB2, XPC) and DSB/R (MRE11A, PRKDC/DNAPKc, RAD50, XRCC6/Ku70) genes only in patients’ BMPCs; no significant changes were observed in PBMCs from patients or HC. Together, our findings demonstrate that panobinostat significantly increased the melphalan sensitivity of malignant BMPCs without increasing the melphalan sensitivity of PBMCs from the same patients, thus paving the way for combination therapies in MM with improved anti-myeloma efficacy and lower side effects.

The BLM helicase is a new therapeutic target in multiple myeloma involved in replication stress survival and drug resistance.
    Frontiers in immunology, 2022, Volume: 13

    Multiple myeloma (MM) is a hematologic cancer characterized by accumulation of malignant plasma cells in the bone marrow. To date, no definitive cure exists for MM and resistance to current treatments is one of the major challenges of this disease. The DNA helicase BLM, whose depletion or mutation causes the cancer-prone Bloom's syndrome (BS), is a central factor of DNA damage repair by homologous recombination (HR) and genomic stability maintenance. Using independent cohorts of MM patients, we identified that high expression of BLM is associated with a poor outcome with a significant enrichment in replication stress signature. We provide evidence that chemical inhibition of BLM by the small molecule ML216 in HMCLs (human myeloma cell lines) leads to cell cycle arrest and increases apoptosis, likely by accumulation of DNA damage. BLM inhibition synergizes with the alkylating agent melphalan to efficiently inhibit growth and promote cell death in HMCLs. Moreover, ML216 treatment re-sensitizes melphalan-resistant cell lines to this conventional therapeutic agent. Altogether, these data suggest that inhibition of BLM in combination with DNA damaging agents could be of therapeutic interest in the treatment of MM, especially in those patients with high BLM expression and/or resistance to melphalan.

Evaluating the incidence of engraftment syndrome with different melphalan formulations in adult multiple myeloma and immunoglobulin light chain amyloidosis patients undergoing autologous hematopoietic cell transplantation.
    Journal of oncology pharmacy practice : official publication of the International Society of Oncology Pharmacy Practitioners, 2022, Volume: 28, Issue:2

    Engraftment syndrome (ES) is a common complication of autologous hematopoietic cell transplantation (HCT). The difference in incidence of ES between melphalan formulations has not been widely reported throughout the literature and would allow for a more comprehensive understanding of the advantages and disadvantages of both melphalan formulations.. This retrospective, single-center, observational study evaluated 83 adult multiple myeloma and immunoglobulin light chain amyloidosis patients who received either propylene glycol-containing (PG) or propylene glycol-free (PG-free) melphalan 140 mg/m. The incidence of ES for PG and PG-free melphalan did not differ significantly, 14/39 (35.9%) and 12/44 (27.3%) (P = 0.4), respectively. No potential risk factors for ES were identified on multivariate logistic regression analysis. A statistically significant difference in number of days to engraftment was identified for PG and PG-free melphalan, 15.56 vs. 13.82 days (P = 0.01), respectively; although, this did not translate to a decrease in LOS, 19.9 vs. 18.59 days (P = 0.14).. The incidence of ES did not differ significantly between melphalan formulations. Future research is needed to determine whether the faster time to engraftment seen with PG-free melphalan may translate to a decrease in LOS.

Outpatient autologous stem cell transplantation in Royal Hobart Hospital, Tasmania: a single-centre, retrospective review in the Australian setting.
    Internal medicine journal, 2022, Volume: 52, Issue:7

    Several international centres have published their experiences with outpatient autologous stem cell transplantation (ASCT) as treatment of haematological malignancies.. In this single-centre retrospective review, we aim to examine the outcomes of outpatient autograft and review healthcare resource utilisation in the pre-cytopenic period.. Patients undergoing ASCT in Royal Hobart Hospital, Tasmania between 2008 and 2018 had their records reviewed and key outcomes data collected based on whether they received inpatient/outpatient ASCT. An outpatient ASCT was defined as conditioning as an outpatient; patients could then be managed with an elective admission during the cytopenic period or admission only when clinically indicated.. Of 231 ASCT performed, 135 (58%) were as outpatients: 59 used carmustine-etoposide-cytarabine-melphalan conditioning for lymphoma (BEAM-ASCT) and 76 used high-dose melphalan for myeloma and amyloidosis (MEL-ASCT). Approximately one-third of patients undergoing outpatient ASCT were admitted electively during nadir period; the majority of patients required minimal interventions prior to this time. The most common causes for unplanned hospitalisation (which occurred in 71 (80%) of the 89 planned outpatient transplants) were febrile neutropenia (39%) and mucositis (35%). Age was the only risk factor identified to increase risk of requiring unplanned hospitalisation. Use of oral antibiotic prophylaxis reduced febrile neutropenia rates among melphalan outpatient ASCT. Outpatient ASCT led to significantly reduced inpatient bed-days and overall cost (approximately A$13 000-A$16 000) compared with inpatient autografts, with no significant differences in engraftment, rates of febrile neutropenia, intensive care admissions or mortality.. Outpatient autografts may save healthcare resources without compromising patient outcomes.

Netupitant/palonosetron without dexamethasone for preventing nausea and vomiting in patients with multiple myeloma receiving high-dose melphalan for autologous stem cell transplantation: a single-center experience.
    Supportive care in cancer : official journal of the Multinational Association of Supportive Care in Cancer, 2022, Volume: 30, Issue:1

    Chemotherapy-induced nausea and vomiting (CINV) is one of the most frequent adverse events compromising quality of life (QoL) in patients undergoing autologous stem cell transplantation (ASCT). However, CINV prophylaxis is still lacking uniformity for high-dose melphalan (HDM), which is used to condition patients with multiple myeloma (MM). Netupitant/palonosetron (NEPA) is administered with dexamethasone (DEXA) for CINV prevention in several chemotherapy regimens. Our study aims to assess the efficacy of NEPA, without DEXA, in preventing CINV in 106 adult patients with MM receiving HDM and ASCT. All patients had antiemetic prophylaxis with multiple doses of NEPA 1 h before the start of conditioning and after 72 h and 120 h. A complete response (CR) was observed in 99 (93%) patients at 120 h (overall phase). The percentage of patients with complete control was 93%. The CR rate during the acute phase was 94% (n = 100). During the delayed phase, the CR rate was 95% (n = 101). Grade 1 nausea and vomiting were experienced by 82% and 12% of the patients, respectively. Grade 2 nausea was reported in 18% and vomiting in 10% of patients. Our results showed, for the first time, that NEPA, without DEXA, was a well-tolerated and effective antiemetic option for MM patients receiving HDM followed by ASCT.

CD4+ T Cell Dependent B Cell Recovery and Function After Autologous Hematopoietic Stem Cell Transplantation.
    Frontiers in immunology, 2021, Volume: 12

    High-dose chemotherapy followed by autologous hematopoietic stem cell transplantation (auto-HSCT) represents a standard treatment regime for multiple myeloma (MM) patients. Common and potentially fatal side effects after auto-HSCT are infections due to a severely compromised immune system with hampered humoral and cellular immunity. This study delineates in depth the quantitative and functional B cell defects and investigates underlying extrinsic or intrinsic drivers.. Peripheral blood of MM patients undergoing high-dose chemotherapy and auto-HSCT (before high-dose chemotherapy and in early reconstitution after HSCT) was studied. Absolute numbers and distribution of B cell subsets were analyzed. Quantitative B cell defects including a shift in the B cell subset distribution occurred after auto-HSCT. Functionally, these patients showed an impaired TD as well as TI B cell immune response. Individual functional responses correlated with quantitative alterations of CD19+, CD4+, memory B cells and marginal zone-like B cells. The TD B cell function could be partially restored upon stimulation with CD40L/IL-21, successfully inducing B cell proliferation and differentiation into plasmablasts and immunoglobulin secreting cells.. Quantitative and functional B cell defects contribute to the compromised immune defense in MM patients undergoing auto-HSCT. Functional recovery upon TD stimulation and correlation with CD4+ T cell numbers, indicate these as extrinsic drivers of the functional B cell defect. Observed correlations of CD4+, CD19+, memory B and MZ-like B cell numbers with the B cell function suggest that these markers should be tested as potential biomarkers in prospective studies.

Serological Response to Vaccination after Autologous Transplantation for Multiple Myeloma Is Associated with Improved Progression-Free and Overall Survival.
    Transplantation and cellular therapy, 2021, Volume: 27, Issue:3

    Revaccination after autologous hematopoietic cell transplantation (AHCT) is recommended in post-HCT survivorship guidelines to restore humoral immunity. Data on seroconversion after AHCT and vaccination in multiple myeloma (MM) patients are limited. We investigated the feasibility and effectiveness of vaccination post-AHCT and analyzed the restoration of humoral immunity and patient prognosis. Anti-pathogen titers were measured within a median of 2 days before and 96 days after AHCT and following revaccination in 139 MM patients who had a first AHCT from 2013 to 2016. Most (84%) patients received at least one dose of any planned vaccines. High-dose melphalan with AHCT restored measurable immunity in 18% of patients. In an additional >60% of patients, seroconversion occurred after vaccination; however, despite vaccination, 20% of patients remained seronegative for most pathogens. Attainment of MM complete response post-AHCT was associated with higher rates of seroconversion which yielded significantly longer progression-free and overall survival. Our study demonstrates the feasibility of post-AHCT vaccination, supporting measurement of post-vaccination titers to determine which patients should be considered for antimicrobial prophylaxis, as seroconversion does not occur in all patients. Titer seroconversion is a potential indicator of the immunological effects of AHCT, with restoration of humoral immunity demonstrating improved survival.

Minimal residual disease in multiple myeloma: why, when, where.
    Hematology. American Society of Hematology. Education Program, 2021, 12-10, Volume: 2021, Issue:1

    Improvements in multiple myeloma therapy have led to deeper responses that are beyond the limit of detection by historical immunohistochemistry and conventional flow cytometry in bone marrow samples. In parallel, more sensitive techniques for assessing minimal residual disease (MRD) through next-generation flow cytometry and sequencing have been developed and are now routinely available. Deep responses when measured by these assays correspond with improved outcomes and survival. We review the data supporting MRD testing as well as its limitations and how it may fit in with current and future clinical practice.

Vitamin E Oil Incorporated Liposomal Melphalan and Simvastatin: Approach to Obtain Improved Physicochemical Characteristics of Hydrolysable Melphalan and Anticancer Activity in Combination with Simvastatin Against Multiple Myeloma.
    AAPS PharmSciTech, 2021, Dec-14, Volume: 23, Issue:1

    The objective of this research was to develop vitamin E oil (VEO)-loaded liposomes for intravenous delivery and to study the VEO effect on melphalan (MLN) loading, release, and stability. Further, the research aim was to determine the in vitro anticancer activity and in vivo systemic toxicity of MLN and simvastatin (SVN) combinations, for repurposing SVN in multiple myeloma. The liposomes were prepared by thin-film hydration technique. The optimized liposomes were surface modified with Pluronic F108, lyophilized, and evaluated for mean particle size, MLN content and release behavior, and in vitro hemolysis, cytotoxicity, and macrophage uptake characteristics. Further, in vivo acute toxicity of plain MLN + SVN combination was determined in comparison to their liposomal combination. The VEO alone and in combination with D-α-tocopheryl polyethylene glycol 1000 succinate (TPGS) has significantly increased the MLN and SVN loading. The reconstituted liposomes showed the mean particle size below 200 nm (cryo-transmission electron microscope analysis also revealed the liposome formation). In presence of VEO, the liposomes have shown substantially controlled drug release, lower hemolysis, sustained cytotoxicity, lower phagocytosis, and moderately improved chemical stability. Besides, the effect of liposomal combination on mice bodyweight is found substantially lower than the plain drug combination. In conclusion, the VEO could be used along with phospholipids and cholesterol to develop liposomal drugs with improved physicochemical characteristics. Further, the interesting cytotoxicity study results indicated that SVN could be repurposed in combination with anticancer drug MLN against multiple myeloma; liposomal drugs could be preferred to obtain improved efficacy with decreased systemic toxicity.

Coincident remission of ankylosing spondylitis after autologous stem cell transplantation for multiple myeloma.
    Journal of oncology pharmacy practice : official publication of the International Society of Oncology Pharmacy Practitioners, 2021, Volume: 27, Issue:1

    Ankylosing spondylitis is an autoimmune disease with chronic inflammation of the spine and sacroiliac joints that is commonly treated with immunosuppressants including disease-modifying antirheumatic drugs and anti-tumor necrosis factor alpha therapy.. A 75-year-old female with active ankylosing spondylitis on treatment with etanercept was referred to us for newly diagnosed IgG kappa free light chain multiple myeloma. After failing induction with revlimid, bortezomib, and dexamethasone, she was initiated on carfilzomib. Following the achievement of adequate response to induction, she underwent an autologous hematopoietic stem cell transplant selected for CD34+ cells with melphalan 200mg/m. Although our patient had a coincident and unprecedented resolution of ankylosing spondylitis after receiving the hematopoietic stem cell transplant, this case consolidates the idea of transplant as a potential treatment option for ankylosing spondylitis and other rheumatological conditions.

Long-term outcomes of innovator versus generic melphalan formulation in autologous hematopoietic cell transplantation for multiple myeloma.
    Hematology/oncology and stem cell therapy, 2021, Volume: 14, Issue:2

    Most data on autologous hematopoietic cell transplantation (auto-HCT) in myeloma are based on the use of innovator formulation of melphalan. Comparative bioequivalence and efficacy studies of generic melphalan are lacking.. In this retrospective study, we report long-term outcomes of auto-HCT in myeloma using innovator (Alkeran, Aspen Pharma; n = 41) and generic melphalan (Alkacel, Celon Labs, India; n = 55) formulations. All consecutive patients at a single center from the period 2011-2018 were included.. The median follow-up in the innovator and generic groups was 61.7 and 32.5 months, respectively. Both groups were matched for age, sex, stage, and myeloma response. There were significantly more patients in the innovator melphalan group who were administered melphalan at a reduced dose at physician discretion (26.8% vs. 3.6%, p = .001). There were significantly more patients with grade 3 or higher mucositis (68.3% vs. 38.1%, p < .0001) and grade 3 or higher diarrhea (85.4% vs. 50.1%, p < .0001) in the innovator group. The median duration of hospital stay was significantly longer in the innovator group (19 days vs. 15.5 days, p < .0001). There were significantly more patients in the generic group who received standard maintenance (94.5% vs. 34.1%, p < .0001). Despite the differences in the melphalan dose and post-transplant strategies, the 4-year progression-free survival and overall survival were not significantly different in the two groups (58% vs. 63%, p = .7, 71% vs. 72%, p = .4, respectively).. Long-term efficacy comparison is helpful in the absence of postmarketing bioequivalence studies of generic melphalan.

Subcutaneous daratumumab plus standard treatment regimens in patients with multiple myeloma across lines of therapy (PLEIADES): an open-label Phase II study.
    British journal of haematology, 2021, Volume: 192, Issue:5

    Daratumumab is a CD38-targeting monoclonal antibody approved for intravenous (IV) infusion for multiple myeloma (MM). We describe the Phase II PLEIADES study of a subcutaneous formulation of daratumumab (DARA SC) in combination with standard-of-care regimens: DARA SC plus bortezomib/lenalidomide/dexamethasone (D-VRd) for transplant-eligible newly diagnosed MM (NDMM); DARA SC plus bortezomib/melphalan/prednisone (D-VMP) for transplant-ineligible NDMM; and DARA SC plus lenalidomide/dexamethasone (D-Rd) for relapsed/refractory MM. In total, 199 patients were treated (D-VRd, n = 67; D-VMP, n = 67; D-Rd, n = 65). The primary endpoints were met for all cohorts: the ≥very good partial response (VGPR) rate after four 21-day induction cycles for D-VRd was 71·6% [90% confidence interval (CI) 61·2-80·6%], and the overall response rates (ORRs) for D-VMP and D-Rd were 88·1% (90% CI 79·5-93·9%) and 90·8% (90% CI 82·6-95·9%). With longer median follow-up for D-VMP and D-Rd (14·3 and 14·7 months respectively), responses deepened (ORR: 89·6%, 93·8%; ≥VGPR: 77·6%, 78·5%), and minimal residual disease-negativity (10

Copy number evolution and its relationship with patient outcome-an analysis of 178 matched presentation-relapse tumor pairs from the Myeloma XI trial.
    Leukemia, 2021, Volume: 35, Issue:7

    Structural chromosomal changes including copy number aberrations (CNAs) are a major feature of multiple myeloma (MM), however their evolution in context of modern biological therapy is not well characterized. To investigate acquisition of CNAs and their prognostic relevance in context of first-line therapy, we profiled tumor diagnosis-relapse pairs from 178 NCRI Myeloma XI (ISRCTN49407852) trial patients using digital multiplex ligation-dependent probe amplification. CNA profiles acquired at relapse differed substantially between MM subtypes: hyperdiploid (HRD) tumors evolved predominantly in branching pattern vs. linear pattern in t(4;14) vs. stable pattern in t(11;14). CNA acquisition also differed between subtypes based on CCND expression, with a marked enrichment of acquired del(17p) in CCND2 over CCND1 tumors. Acquired CNAs were not influenced by high-dose melphalan or lenalidomide maintenance randomization. A branching evolution pattern was significantly associated with inferior overall survival (OS; hazard ratio (HR) 2.61, P = 0.0048). As an individual lesion, acquisition of gain(1q) at relapse was associated with shorter OS, independent of other risk markers or time of relapse (HR = 2.00; P = 0.021). There is an increasing need for rational therapy sequencing in MM. Our data supports the value of repeat molecular profiling to characterize disease evolution and inform management of MM relapse.

VLA4-Targeted Nanoparticles Hijack Cell Adhesion-Mediated Drug Resistance to Target Refractory Myeloma Cells and Prolong Survival.
    Clinical cancer research : an official journal of the American Association for Cancer Research, 2021, 04-01, Volume: 27, Issue:7

    In multiple myeloma, drug-resistant cells underlie relapse or progression following chemotherapy. Cell adhesion-mediated drug resistance (CAM-DR) is an established mechanism used by myeloma cells (MMC) to survive chemotherapy and its markers are upregulated in residual disease. The integrin very late antigen 4 (VLA4; α. We synthetized 20 nm VLA4-targeted micellar nanoparticles (V-NP) carrying DiI for tracing or a novel camptothecin prodrug (V-CP). Human or murine MMCs, alone or with stroma, and immunocompetent mice with orthotopic multiple myeloma were used to track delivery of NPs and response to treatments.. V-NPs selectively delivered their payload to MMCs. V-CP may be a safe and effective strategy to prevent or treat relapsing or refractory myeloma. V-NP targeting of resistant cells may suggest a new approach to environment-induced resistance in cancer.

Significant salivary changes in relation to oral mucositis following autologous hematopoietic stem cell transplantation.
    Bone marrow transplantation, 2021, Volume: 56, Issue:6

    The aim of this multicentre, longitudinal study was to determine salivary changes in relation to oral mucositis (OM) in multiple myeloma patients following high-dose melphalan and autologous hematopoietic stem cell transplantation (ASCT). Unstimulated and stimulated whole-mouth saliva samples (UWS and SWS) were collected before ASCT, 1×/wk during the hospitalisation phase, and 3 and 12 months post-ASCT. During the hospitalisation period OM was scored 3×/wk (WHO system). Flow rate, pH, total protein concentration (Nanodrop), albumin, lactoferrin, neutrophil defensin-1 (HNP1), total IgA and S100A8/A9 (ELISA) were determined. Mixed models were used to evaluate differences between ulcerative (u)OM (≥2 WHO, n = 20) and non-uOM (n = 31) groups. Until 18 days after ASCT, flow rate, pH, total IgA and HNP1 levels decreased in UWS and/or SWS, while log lactoferrin levels were significantly increased (UWS: p = 0.016 95% CI [0.36, 3.58], SWS: p < 0.001 95% CI [1.14, 3.29]). Twelve months post-ASCT, salivary protein levels were similar to baseline except for log total IgA, which was higher (UWS: p < 0.001 95% CI [0.49, 1.29], SWS: p < 0.001 95% CI [0.72, 1.45]). No differences between uOM and non-uOM groups were observed. Changes in salivary proteins indicated an inflammatory reaction in salivary glands coinciding with mucosal and systemic reactions in response to high-dose melphalan.

Cost-Effectiveness Analysis of Adding Daratumumab to a Regimen of Bortezomib, Melphalan, and Prednisone in Newly Diagnosed Multiple Myeloma.
    Advances in therapy, 2021, Volume: 38, Issue:5

    The ALCYONE trial found that daratumumab in combination with bortezomib, melphalan, and prednisone (D-VMP) can significantly improve progression-free survival (PFS) and overall survival (OS) for patients with transplant-ineligible, newly diagnosed multiple myeloma (MM) in China. In the present study, we evaluated the cost-effectiveness of D-VMP versus VMP for patients with newly diagnosed MM in China.. A Markov model was used to estimate the cost-effectiveness of frontline D-VMP versus VMP for MM. The life years (LYs), quality-adjusted LYs (QALYs), and incremental cost-effectiveness ratio (ICER) were calculated. A series of sensitivity analyses was performed to assess the robustness of the model and address uncertainties in variable estimates. Subgroup analysis was also performed.. D-VMP provided an additional 2.99 LYs and 1.67 QALYs compared with VMP, with incremental $64,920 per LY and $116,015 per QALY gained. The results of the univariable sensitivity analysis showed that the parameter that had the greatest impact on the ICER was the cost of subsequent treatment and daratumumab. When the cost of daratumumab was 100%, 70%, 50%, and 30% of the current price, the probability of D-VMP being cost-effective was 2.49%, 16.11%, 39.09%, and 70.73% at the willingness-to-pay (WTP) threshold of $30,950/QALY, respectively. The results demonstrated that the ICER in all subgroups remained > $30,950/QALY.. D-VMP versus VMP is likely to exceed the commonly accepted values of cost-effectiveness in patients with transplant-ineligible, newly diagnosed MM in China.

Autologous Stem Cell Transplantation for Myeloma: Cytoreduction or an Immunotherapy?
    Frontiers in immunology, 2021, Volume: 12

    The incidence of multiple myeloma (MM), a bone marrow (BM) resident hematological malignancy, is increasing globally. The disease has substantial morbidity and mortality and remains largely incurable. Clinical studies show that autologous stem cell transplantation (ASCT) remains efficacious in eligible patients, providing a progression free survival (PFS) benefit beyond novel therapies alone. Conventionally, improved PFS after ASCT is attributed to cytoreduction from myeloablative chemotherapy. However, ASCT results in immune effects beyond cytoreduction, including inflammation, lymphodepletion, T cell priming

Treatment patterns and outcomes in real-world transplant-ineligible patients newly diagnosed with multiple myeloma.
    Annals of hematology, 2021, Volume: 100, Issue:7

    Despite the significant proportion of older patients with newly diagnosed multiple myeloma (MM), most clinical trials driving therapeutic decisions in routine practice include younger and presumably healthier patients than those in the real world. Furthermore, longitudinal studies suggest that elderly, transplant-ineligible patients with MM are not benefitting enough from new anti-MM agents. We retrospectively analyzed the profile of and treatment patterns and outcomes in 675 transplant-ineligible patients with MM who started frontline therapy in routine practice. The mean (SD) age was 75.6 (6.7) years; 152 (47.4%) had Eastern Cooperative Oncology Group performance status (ECOG PS) 2-4, and 73 (25.1%) had high cytogenetic risk. The most frequent frontline therapy was non-VMP bortezomib-based regimens (n=207; 30.7%), which were more frequent among patients with ECOG PS 0/1 and higher risk (e.g., international staging system (ISS) stage III, severely impaired glomerular filtrate rate (GFR), high lactate dehydrogenase (LDH), and high-risk cytogenetics); 185 patients (27.4%) started an attenuated (lite) VMP regimen, and 159 (23.6%) a VMP (VISTA) regimen. Median progression-free survival and overall survival (OS) were 15.3 months (95%CI 14.0-16.9) and 33.5 months (95%CI 29.1-37.2), respectively; 405 patients (78.2%) achieved partial response or better. Age, ECOG PS, ISS stage, serum LDH, GFR, cytogenetic risk, and treatment regimen significantly influenced OS. In this study, a remarkable proportion of transplant-ineligible patients with MM were older, frontline regimens were highly heterogeneous, and patients at higher risk often received less efficacious combinations. These findings suggest that clinicians have limited objective criteria for therapeutic decisions for this patient group.

Cumulative exposure to melphalan chemotherapy and subsequent risk of developing acute myeloid leukemia and myelodysplastic syndromes in patients with multiple myeloma.
    European journal of haematology, 2021, Volume: 107, Issue:2

    The aim of this study was to determine risk factors for development of acute myeloid leukemia/myelodysplastic syndromes (AML/MDS) in patients with multiple myeloma (MM).. We identified all patients diagnosed with MM in Sweden from January 1st, 1958 to December 31, 2011. A total of 26 627 patients were diagnosed with MM with during the study period. Of these, 124 patients (0.5%) developed subsequent AML/MDS. For each patient with MM and a subsequent AML/MDS diagnosis, we randomly selected a matched (age, sex, and date of MM diagnosis) MM patient without a subsequent second malignancy diagnosis.. The cumulative melphalan exposure was significantly higher (OR = 2.8, 95% CI 1.7-5.2; P < .001) among cases (median 988 mg; IQR 644-1640) compared with controls (median 578 mg; IQR 360-967). Median time to AML/MDS development was 3.8 years (IQR 2.8-5.8). Risk of AML/MDS was not statistically altered by M protein isotype, anemia, renal failure, hypercalcemia, lytic bone lesions, or radiation therapy.. In this nationwide population-based study, we show that increased cumulative doses of alkylating therapy with melphalan increases the subsequent risk of developing AML/MDS in patients with MM. Given improved survival in MM patients over the last decade future studies will be important to better define long-term risks.

Metabolic Changes Are Associated with Melphalan Resistance in Multiple Myeloma.
    Journal of proteome research, 2021, 06-04, Volume: 20, Issue:6

    Multiple myeloma is an incurable hematological malignancy that impacts tens of thousands of people every year in the United States. Treatment for eligible patients involves induction, consolidation with stem cell rescue, and maintenance. High-dose therapy with a DNA alkylating agent, melphalan, remains the primary drug for consolidation therapy in conjunction with autologous stem-cell transplantation; as such, melphalan resistance remains a relevant clinical challenge. Here, we describe a proteometabolomic approach to examine mechanisms of acquired melphalan resistance in two cell line models. Drug metabolism, steady-state metabolomics, activity-based protein profiling (ABPP, data available at PRIDE: PXD019725), acute-treatment metabolomics, and western blot analyses have allowed us to further elucidate metabolic processes associated with melphalan resistance. Proteometabolomic data indicate that drug-resistant cells have higher levels of pentose phosphate pathway metabolites. Purine, pyrimidine, and glutathione metabolisms were commonly altered, and cell-line-specific changes in metabolite levels were observed, which could be linked to the differences in steady-state metabolism of naïve cells. Inhibition of selected enzymes in purine synthesis and pentose phosphate pathways was evaluated to determine their potential to improve melphalan's efficacy. The clinical relevance of these proteometabolomic leads was confirmed by comparison of tumor cell transcriptomes from newly diagnosed MM patients and patients with relapsed disease after treatment with high-dose melphalan and autologous stem-cell transplantation. The observation of common and cell-line-specific changes in metabolite levels suggests that omic approaches will be needed to fully examine melphalan resistance in patient specimens and define personalized strategies to optimize the use of high-dose melphalan.

Full or intensity-reduced high-dose melphalan and single or double autologous stem cell transplant with or without bortezomib consolidation in patients with newly diagnosed multiple myeloma.
    European journal of haematology, 2021, Volume: 107, Issue:5

    A post hoc subgroup analysis of two phase III trials (NCT00416273, NCT00416208) was carried out to investigate the influence of 100/140 and 200 mg/m² melphalan as well as single/double autologous stem cell transplantation (ASCT) on progression-free survival (PFS). Additionally, the effect of bortezomib consolidation on PFS was analyzed.. Following induction therapy and high-dose melphalan with subsequent ASCT, patients with newly diagnosed multiple myeloma (NDMM) were randomized 1:1 to either four 35-day cycles of bortezomib consolidation (1.6 mg/m² IV on days 1, 8, 15, 22) or observation.. Of the 340 patients included in this analysis, 13.5% received 1 × MEL100/140, 22.9% 2 × MEL100/140, 31.2% 1 × MEL200, and 32.4% 2 × MEL200. With higher cumulative melphalan dose, PFS improved (P = .0085). PFS curves of patients treated with 2 × MEL100/140 and 1 × MEL200 were very similar. The superior dose effect of MEL200 over MEL100/140 was non-existent in the bortezomib consolidation arm but pronounced in the observation arm (P = .0015). Similarly, double ASCT was only beneficial in patients without bortezomib consolidation (P = .0569).. Full dose melphalan and double transplantation seem advantageous only as long as patients are not receiving bortezomib consolidation afterwards.

Bortezomib-based therapy for newly diagnosed multiple myeloma patients ineligible for autologous stem cell transplantation: Czech Registry Data.
    European journal of haematology, 2021, Volume: 107, Issue:4

    This study compared the use of bortezomib in different combination regimens in newly diagnosed multiple myeloma (NDMM) patients who were transplant ineligible.. We analyzed data from the Registry of Monoclonal Gammopathies (RMG) of the Czech Myeloma Group (CMG) to provide real-world evidence of outcome for 794 newly diagnosed MM transplant ineligible patients. The most frequently used regimen was VCd (bortezomib-cyclophosphamide-dexamethasone) (47.5%) over VMP (bortezomib-melphalan-prednisone) (21.7%), BDd (bortezomib-doxorubicin-dexamethasone) (9.8%), and VTd (bortezomib-thalidomide-dexamethasone) (2.9%).. The overall response rate (ORR) was 69.2% (478/691), including 12.6% (≥ CR); 34.7% very good partial responses (VGPR); and 21.9% partial responses (PR). Among triplet regimens, VMP was the most effective regimen compared to VCd, BDd, and VTd. Median PFS was 22.3 vs. 18.5 vs. 13.7 vs. 13.8 mo, (P = .275), respectively, and median OS was 49 vs. 41.7 vs. 37.9 vs. 32.2 mo (P = .004), respectively. The most common grade 3-4 toxicities were anemia in 17.4% and infections in 18% of patients.. Our study confirmed that bortezomib-based treatment is effective and safe in NDMM transplant ineligible patients, especially VMP, which was identified as superior between bortezomib-based induction regimens not only in clinical trials, but also in real clinical practice.

    In the phase 3 ALCYONE study, daratumumab plus bortezomib/melphalan/prednisone (D-VMP) versus bortezomib/melphalan/prednisone (VMP) significantly improved progression-free survival (PFS) and overall survival (OS) in transplant-ineligible, newly diagnosed multiple myeloma (NDMM) patients. We present a subgroup analysis of ALCYONE by patient frailty status.. Frailty assessment was performed retrospectively using age, Charlson comorbidity index, and baseline Eastern Cooperative Oncology Group performance status score. Patients were classified as fit (0), intermediate (1), or frail (≥2); a nonfrail category combined fit and intermediate patients.. Our findings support the clinical benefit of D-VMP in transplant-ineligible NDMM patients enrolled in ALCYONE, regardless of frailty status.

Outcomes of upfront autologous hematopoietic cell transplantation in patients with multiple myeloma who are 75 years old or older.
    Cancer, 2021, 11-15, Volume: 127, Issue:22

    Consolidative autologous hematopoietic stem cell transplantation (AHCT) is commonly used for patients with multiple myeloma (MM). We studied AHCT use and outcomes in patients with MM ≥75 years old.. Patients with MM ≥75 years old receiving AHCT between 2013 and 2017 in the United States were identified using the Center for International Blood and Marrow Transplant Research database. Relapse and/or progression (REL), progression-free survival (PFS), and overall survival (OS) were modeled using Cox proportional hazards models. Covariates used were age, sex, Karnofsky performance score (KPS), HCT-comorbidity index (HCT-CI), International Staging System and/or Durie-Salmon stage, high-risk cytogenetics, melphalan dose, and disease status at and 1 year after transplant. AHCT utilization rate using the Surveillance, Epidemiology, and End Results database was used to estimate specific incidence among ≥75 years old by race and gender.. Of 360 patients, 63% were male, 84% were White, 56% had KPS <90, and 57% had HCT-CI ≥3. The 100-day transplant-related mortality was 1% (0%-2%) with a 2-year REL rate of 27% (95% confidence interval [CI], 22%-33%), PFS of 66% (95% CI, 60%-72%), and OS of 83% (95% CI, 78%-87%). On multivariate analysis, only high-risk cytogenetics was associated with REL risk and decreased PFS. In White males, transplant utilization rate was 5.2%-5.8% compared to 3.5%-4.0% in African American males (P = .02). There was 3.37-3.79% transplant utilization in White females compared to 1.88-2.12% in African American females (P < .01).. The use of AHCT was associated with excellent 2-year outcomes in this selected MM population ≥75 years old. Transplant utilization for patients ≥75 years old remains low with significant racial and gender disparities.

Toxicity and survival outcomes of autologous stem cell transplant in multiple myeloma patients with renal insufficiency: an institutional comparison between two eras.
    Bone marrow transplantation, 2020, Volume: 55, Issue:3

    Autologous stem cell transplant (ASCT) is a feasible treatment option for multiple myeloma (MM) patients with renal insufficiency; however, these patients tend to experience higher rates of drug toxicity and transplant-related mortality (TRM) during ASCT. Recent adoption of bortezomib-based induction regimens and dose reduction of melphalan during conditioning may improve outcomes in this population. In this single center retrospective study, we compared the toxicity and survival outcomes of 96 MM patients with renal insufficiency undergoing ASCT between two eras: 1998-2007 and 2008-2016. The proportion of dialysis dependent patients was similar in both groups (49 and 45%). We found no TRM in those transplanted more recently as compared with 13% in the older era of ASCT. There were significantly more high grade (grades 3-4) toxicities in the older era of ASCT including high grade electrolyte abnormalities, mucositis, delirium, and bleeding. Patients transplanted more recently had significantly higher overall response rate (ORR) as well as deeper responses to ASCT (≥VGPR in 79% vs 39%). Progression-free survival (PFS) was prolonged by 26 months in the more recent era compared with the older era. Overall, improvements in treatment regimens have resulted in reduced TRM and toxicities for patients with renal insufficiency undergoing ASCT.

Inhibition of HSP90 overcomes melphalan resistance through downregulation of Src in multiple myeloma cells.
    Clinical and experimental medicine, 2020, Volume: 20, Issue:1

    Multiple myeloma (MM) is the second most common hematologic malignancy. In spite of the development of new therapeutic agents, MM remains incurable due to multidrug resistance (MDR) and the 5-year survival rate is approximately 50%. Thus, further study is needed to investigate the mechanism of MDR and improve MM prognosis. Heat shock protein 90 (HSP90) is a molecular chaperone that is responsible for the stability of a number of client proteins, most of which are involved in tumor progression. Therefore, HSP90 inhibitors represent potential new therapeutic agents for cancer. Furthermore, inhibition of HSP90 leads to degradation of client proteins, overcoming acquired anti-cancer drug resistance. In this study, we assessed the role of HSP90 in MDR using established melphalan-resistant MM cells. We found that expression of HSP90 was higher in melphalan-resistant MM cells than in parent cells and that HSP90 inhibitors KW-2478 and NUV-AUY922 restored drug sensitivity to the level observed in parent cells. Activation of the unfolded protein response is a hallmark of MM, and expression of endoplasmic reticulum stress signaling molecules is reduced in melphalan-resistant cells; however, KW-2478 did not affect endoplasmic reticulum stress signaling. We demonstrated that treatment with KW-2478 decreased expression of Src, a client of HSP90, and suppressed the activity of ERK, Akt, and NF-κB. Our findings indicate that inhibition of HSP90 results in suppression of Src and its downstream effectors, including ERK, Akt, and NF-κB, and therefore that HSP90 inhibitors could be useful for treatment of MDR MM.

A matching-adjusted indirect treatment comparison (MAIC) of daratumumab-bortezomib-melphalan-prednisone (D-VMP) versus lenalidomide-dexamethasone continuous (Rd continuous), lenalidomide-dexamethasone 18 months (Rd 18), and melphalan-prednisone-thalidomid
    Leukemia & lymphoma, 2020, Volume: 61, Issue:3

    D-VMP is a novel treatment for transplant-ineligible newly diagnosed multiple myeloma (TIE NDMM). D-VMP significantly prolonged PFS versus VMP in the ALCYONE trial. The FIRST trial investigated Rd given in 28-day cycles until disease progression, Rd for 18 cycles, and MPT for 12 cycles for TIE NDMM. As no randomized controlled trials comparing D-VMP to standard-of-care regimens such as those in FIRST are available, an MAIC was performed to assess relative OS and PFS for D-VMP from ALYCONE and Rd continuous, Rd 18, and MPT from FIRST. Individual patient data for D-VMP in ALCYONE were weighted to match aggregated baseline patient characteristics for each arm of FIRST. D-VMP significantly improved OS versus MPT and Rd 18, with a trend favoring D-VMP versus Rd continuous. D-VMP performed significantly better than all FIRST comparators for PFS. This MAIC demonstrates OS and PFS benefits for D-VMP versus Rd continuous, Rd 18, and MPT.

Multiple myeloma manifesting as an ocular salmon patch - a case report.
    Orbit (Amsterdam, Netherlands), 2020, Volume: 39, Issue:5

    Multiple myeloma (MM) is the second most prevalent hematologic malignancy after non-Hodgkin lymphoma and is currently considered incurable. Clinical ophthalmic manifestations of MM are rare but at the same time diverse. Ocular surface manifestations of multiple myeloma are uncommon. Conjunctival 'salmon patch' is a typical ocular surface ophthalmological sign with a distinct set of differential diagnoses, including most often ocular adnexal lymphoma. This case report presents a 33-year-old female with a relapse of MM manifesting as a conjunctival 'salmon patch'. The patient initially responded well to medical management including high dose melphalan supported by a third autologous stem cell transplantation (ASCT) and did not require further surgical excision of the ocular lesion. It is suggested that MM should be included in the differential diagnosis of 'salmon patch' conjunctival lesions.

A Small-Molecule Inhibitor Targeting TRIP13 Suppresses Multiple Myeloma Progression.
    Cancer research, 2020, 02-01, Volume: 80, Issue:3

    The AAA-ATPase TRIP13 drives multiple myeloma progression. Here, we present the crystal structure of wild-type human TRIP13 at a resolution of 2.6 Å. A small-molecule inhibitor targeting TRIP13 was identified on the basis of the crystal structure. The inhibitor, designated DCZ0415, was confirmed to bind TRIP13 using pull-down, nuclear magnetic resonance spectroscopy, and surface plasmon resonance-binding assays. DCZ0415 induced antimyeloma activity

Pharmacokinetics and Efficacy of Generic Melphalan Is Comparable to Innovator Formulation in Patients With Multiple Myeloma Undergoing Autologous Stem Cell Transplantation.
    Clinical lymphoma, myeloma & leukemia, 2020, Volume: 20, Issue:2

    High-dose melphalan (MEL) is the standard conditioning regimen used for autologous stem cell transplantation (ASCT) in patients with multiple myeloma (MM). Generic MEL is routinely used in various transplant centers across the world including ours due to its reduced cost and ease of availability. We compared the pharmacokinetics (PK) and the clinical efficacy of generic MEL with that of the innovator formulation in MM patients undergoing ASCT.. Sixty-three patients diagnosed with MM receiving high-dose MEL were included in this study. MEL levels in plasma were measured using a liquid chromatography tandem mass spectrometry (HPLC/MS-MS) protocol and non-linear mixed effects modeling was used to evaluate the PK of the data.. The interindividual variability (IIV) in MEL area under the concentration versus time curve (AUC) and clearance (CL) were 4.39, 5.88-fold for generic, and 4.34, 6.85-fold for the innovator formulation, respectively. The median MEL AUC and CL were comparable between the 2 formulations. The population PK analysis showed age and creatinine CL as the only significant covariates explaining IIV in MEL AUC/CL. Analysis of MEL PK parameters with clinical outcome showed no significant differences in terms of onset and severity of mucositis, day to neutrophil and platelet engraftment, as well as response status on day 100 post ASCT between patients receiving generic or innovator formulations of MEL. In addition, neither MEL AUC nor CL was found to be associated with day +100 response.. Our study suggests that the PK and efficacy of the generic MEL is comparable to the innovator formulation.

Development of a method for clinical pharmacokinetic testing to allow for targeted Melphalan dosing in multiple myeloma patients undergoing autologous transplant.
    British journal of clinical pharmacology, 2020, Volume: 86, Issue:11

    High dose melphalan (HDM) and autologous stem cell transplant (ASCT) is standard of care for multiple myeloma (MM), but there is significant variability in melphalan exposure (area under the plasma drug concentration-time curve, AUC) when using body surface area-based dosing. Our aim was to establish a method of pharmacokinetic (PK) testing for real-time melphalan dose adjustments.. We performed a prospective PK study of melphalan 140 or 200 mg/m. Less than 20% interpatient variation in the day -2 and - 1 AUC was observed. The day -2 range in AUC (4.95-11.28 mg h/L) confirmed significant interpatient variability. The hypothetical total dose ranged from 133-302 mg/m. Here we outline the methods to establish novel melphalan dosing using PK testing in MM patients undergoing ASCT to target a desired melphalan AUC.

Non-cryopreserved peripheral blood stem cells autologous transplantation in multiple myeloma: Bicentric study.
    Transfusion clinique et biologique : journal de la Societe francaise de transfusion sanguine, 2020, Volume: 27, Issue:3

    The objective of this study is to evaluate the toxicity of autologous transplantation of non-frozen peripheral blood stem cells in Moroccan patients with multiple myeloma.. This was a bicentric retrospective study conducted in the Clinical Haematology Department of Mohammed V Military Teaching Hospital and at the Al Madina Clinic in Casablanca. The study period was from January 2015 to June 2019. All patients with multiple myeloma who had undergone an autologous peripheral stem cell transplant without freezing were included. Mobilisation was performed with lenograstim alone and the collected stem cells were stored for 24-48hours in a blood bank refrigerator at a temperature of 4°C. After standard conditioning with high-dose melphalan, the peripheral blood stem cells were reinjected 24 h following conditioning.. Our study finds good feasibility and low toxicity of autologous peripheral stem cell transplantation without freezing in patients with multiple myeloma.

Differences in engraftment with day-1 compared with day-2 melphalan prior to stem cell infusion in myeloma patients receiving autologous stem cell transplant.
    Bone marrow transplantation, 2020, Volume: 55, Issue:11

    We conducted a retrospective study comparing posttransplant outcomes between myeloma patients receiving conditioning melphalan on day-2 vs day-1 for autologous stem cell transplant. Between January 2017 and December 2018, 201 patients received melphalan on day-2 and 166 on day-1 prior to stem cell infusion. Baseline disease and clinical characteristics between the two groups were similar. Although rates of hospitalization were similar between the cohorts, duration of hospital admission was longer for day-1 (median 7 days for day-1 vs 5 days for day-2, p = 0.003). Rates of fever were higher in the day-1 cohort (69% vs 49%, p = 0.0002). Time to platelet and neutrophil engraftment was significantly longer in the day-1 cohort (platelet engraftment median days 17 for day-1 vs 15 for day-2, p < 0.0001, neutrophil engraftment median days 16 for day-1 vs 16 for day-2, p = 0.025). Overall response rate was similar between the cohorts (99% for day-1, vs 100% for day-2). Day-2 melphalan infusions should be considered in preference for day-1 protocols, given the clinically significant delay in platelet and neutrophil engraftment and longer duration of hospitalization with day-1 infusions.

Bortezomib use and outcomes for the treatment of multiple myeloma.
    Internal medicine journal, 2020, Volume: 50, Issue:9

    The public subsidy in Australia of bortezomib (Velcade) for untreated non-transplant multiple myeloma patients was based on the VISTA trial.. To ascertain the health outcomes of bortezomib in 'real world' transplant-ineligible elderly patients, compared to trial data.. Patient and treatment data were extracted from an oncology information system, laboratory information system and medical chart audits for three Queensland public hospitals.. We identified 74 patients; the median age was 75 years. Our cohort comprised 47% patients who were International Staging System stage III, 45% at stage II and 8% at stage I. Patients who had comorbidities, such as cardiac disease (41%), pulmonary disease (14%), diabetes (22%), peripheral neuropathy (14%) and other comorbidities (41%) at baseline were included. The common regimens prescribed were VMP, CVD and VD, and most patients (n = 73) received bortezomib on a once-weekly or twice-a-week basis. The overall response rate was 81%. Half (53%) of the patients did not complete their planned therapy due to toxicity (30%), suboptimal response or disease progression (15%), or death on treatment (8%). Overall survival was 40.7 months and progression free survival was 17.7 months.. Our patients were older, had worse disease characteristics and more comorbidities than patients in the VISTA trial. While response rates were similar, survival outcomes appeared worse. Bortezomib-based treatment in the real world setting still carries a high risk of toxicity in the elderly population.

CD34+ hematopoietic progenitor cell dose as a predictor of engraftment and survival in multiple myeloma patients undergoing autologous stem cell transplantation
    Turkish journal of medical sciences, 2020, 12-17, Volume: 50, Issue:8

    High-dose melphalan and autologous hematopoietic stem cell transplantation (AHSCT) is the standard treatment strategy for multiple myeloma (MM) patients who are eligible for it. The recommended dose of CD34+ hematopoietic progenitor cells (HPCs) for adequate engraftment is above 2 × 106/kg. The aim of this study was to evaluate the relationship between the dose of CD34+HPCs and survival in MM patients who underwent AHSCT at a tertiary care center.. Enrolled in this study were 271 MM patients who underwent AHSCT between 2003 and 2019. Clinical characteristics of the patients, disease status pre-AHSCT, reinfused CD34+ cell doses, and neutrophil and platelet engraftment days were recorded, retrospectively. The patients were divided into 2 groups according to whether the dose of reinfused CD 34+ HPCs was <5 × 106/kg or ≥5 × 106/kg. The groups were compared in terms of engraftment and overall survival (OS) times.. The median age of the patients was 54.8 (33–76) years. The median dose of infused CD34+ HPCs was 5.94 × 106/kg (1.47–59.5 × 106/kg). The median follow-up period was 54 months (4–211). The median OS of the patients was 103 months (11–144). The median neutrophil and platelet engraftment time was 10 (8–24) and 11 (7–40) days. Doses of <5 × 106/kg and ≥5 × 106/kg CD34+ HPC were reinfused in 38.1% and 61.9% of the patients, respectively. There was a negative significant correlation between the reinfused CD34+cell level and neutrophil/platelet engraftment times (r = –0.32, P < 0.001; r = –0.27, P < 0.001, respectively). The median OS times were observed as 103 months (11–144) and 145 months (123–166) for patients who had been administered <5 × 106/kg and ≥5 × 106/kg of CD34+ HPCs, respectively (P = 0.009).. The increased amount of CD34+ autologous hematopoietic stem cell dose after high dose melphalan chemotherapy in MM patients shortened the platelet and neutrophil engraftment time and increased OS. Early platelet engraftment and administration of a CD34+ HPC count that is ≥5 × 106/kg can be considered as predictors of better survival in patients.

No significant difference in the complete response and overall response rate after ASCT was observed between BUMEL and HDMEL. After a median follow-up of 37.3 months in the BUMEL group and 50.8 months in the HDMEL group, the median progression-free survival was calculated to be 32.9 months and 25.2 months (

Accelerated single cell seeding in relapsed multiple myeloma.
    Nature communications, 2020, 07-17, Volume: 11, Issue:1

    Multiple myeloma (MM) progression is characterized by the seeding of cancer cells in different anatomic sites. To characterize this evolutionary process, we interrogated, by whole genome sequencing, 25 samples collected at autopsy from 4 patients with relapsed MM and an additional set of 125 whole exomes collected from 51 patients. Mutational signatures analysis showed how cytotoxic agents introduce hundreds of unique mutations in each surviving cancer cell, detectable by bulk sequencing only in cases of clonal expansion of a single cancer cell bearing the mutational signature. Thus, a unique, single-cell genomic barcode can link chemotherapy exposure to a discrete time window in a patient's life. We leveraged this concept to show that MM systemic seeding is accelerated at relapse and appears to be driven by the survival and subsequent expansion of a single myeloma cell following treatment with high-dose melphalan therapy and autologous stem cell transplant.

Melphalan and Exportin 1 Inhibitors Exert Synergistic Antitumor Effects in Preclinical Models of Human Multiple Myeloma.
    Cancer research, 2020, 12-01, Volume: 80, Issue:23

    High-dose chemotherapy with melphalan followed by autologous transplantation is a first-line treatment for multiple myeloma. Here, we present preclinical evidence that this treatment may be significantly improved by the addition of exportin 1 inhibitors (XPO1i). The XPO1i selinexor, eltanexor, and KOS-2464 sensitized human multiple myeloma cells to melphalan. Human 8226 and U266 multiple myeloma cell lines and melphalan-resistant cell lines (8226-LR5 and U266-LR6) were highly sensitized to melphalan by XPO1i. Multiple myeloma cells from newly diagnosed and relapsed/refractory multiple myeloma patients were also sensitized by XPO1i to melphalan. In NOD/SCIDγ mice challenged with either parental 8226 or U266 multiple myeloma and melphalan-resistant multiple myeloma tumors, XPO1i/melphalan combination treatments demonstrated stronger synergistic antitumor effects than single-agent melphalan with minimal toxicity. Synergistic cell death resulted from increased XPO1i/melphalan-induced DNA damage in a dose-dependent manner and decreased DNA repair. In addition, repair of melphalan-induced DNA damage was inhibited by selinexor, which decreased melphalan-induced monoubiquitination of FANCD2 in multiple myeloma cells. Knockdown of FANCD2 was found to replicate the effect of selinexor when used with melphalan, increasing DNA damage (γH2AX) by inhibiting DNA repair. Thus, combination therapies that include selinexor or eltanexor with melphalan may have the potential to improve treatment outcomes of multiple myeloma in melphalan-resistant and newly diagnosed patients. The combination of selinexor and melphalan is currently being investigated in the context of high-dose chemotherapy and autologous transplant (NCT02780609). SIGNIFICANCE: Inhibition of exportin 1 with selinexor synergistically sensitizes human multiple myeloma to melphalan by inhibiting Fanconi anemia pathway-mediated DNA repair.

ATR addiction in multiple myeloma: synthetic lethal approaches exploiting established therapies.
    Haematologica, 2020, 10-01, Volume: 105, Issue:10

    Therapeutic strategies designed to tinker with cancer cell DNA damage response have led to the widespread use of PARP inhibitors for BRCA1/2-mutated cancers. In the haematological cancer multiple myeloma, we sought to identify analogous synthetic lethality mechanisms that could be leveraged upon established cancer treatments. The combination of ATR inhibition using the compound VX-970 with a drug eliciting interstrand cross-links, melphalan, was tested in in vitro, ex vivo, and most notably in vivo models. Cell proliferation, induction of apoptosis, tumor growth and animal survival were assessed. The combination of ATM inhibition with a drug triggering double strand breaks, doxorucibin, was also probed. We found that ATR inhibition is strongly synergistic with melphalan, even in resistant cells. The combination was dramatically effective in targeting myeloma primary patient cells and cell lines reducing cell proliferation and inducing apoptosis. The combination therapy significantly reduced tumor burden and prolonged survival in animal models. Conversely, ATM inhibition only marginally impacted on myeloma cell survival, even in combination with doxorucibin at high doses. These results indicate that myeloma cells extensively rely on ATR, but not on ATM, for DNA repair. Our findings posit that adding an ATR inhibitor such as VX-970 to established therapeutic regimens may provide a remarkably broad benefit to myeloma patients.

Targeting of the E3 ubiquitin-protein ligase HUWE1 impairs DNA repair capacity and tumor growth in preclinical multiple myeloma models.
    Scientific reports, 2020, 10-28, Volume: 10, Issue:1

    Experimental evidence suggests that ubiquitin-protein ligases regulate a number of cellular processes involved in tumorigenesis. We analysed the role of the E3 ubiquitin-protein ligase HUWE1 for pathobiology of multiple myeloma (MM), a still incurable blood cancer. mRNA expression analysis indicates an increase in HUWE1 expression levels correlated with advanced stages of myeloma. Pharmacologic as well as RNAi-mediated HUWE1 inhibition caused anti-proliferative effects in MM cell lines in vitro and in an MM1.S xenotransplantation mouse model. Cell cycle analysis upon HUWE1 inhibition revealed decreased S phase cell fractions. Analyses of potential HUWE1-dependent molecular functions did not show involvement in MYC-dependent gene regulation. However, HUWE1 depleted MM cells displayed increased DNA tail length by comet assay, as well as changes in the levels of DNA damage response mediators such as pBRCA1, DNA-polymerase β, γH2AX and Mcl-1. Our finding that HUWE1 might thus be involved in endogenous DNA repair is further supported by strongly enhanced apoptotic effects of the DNA-damaging agent melphalan in HUWE1 depleted cells in vitro and in vivo. These data suggest that HUWE1 might contribute to tumour growth by endogenous repair of DNA, and could therefore potentially be exploitable in future treatment developments.

The avoidance of G-CSF and the addition of prophylactic corticosteroids after autologous stem cell transplantation for multiple myeloma patients appeal for the at-home setting to reduce readmission for neutropenic fever.
    PloS one, 2020, Volume: 15, Issue:11

    Autologous stem cell transplantation (ASCT) remains the standard of care for young multiple myeloma (MM) patients; indeed, at-home ASCT has been positioned as an appropriate therapeutic strategy. However, despite the use of prophylactic antibiotics, neutropenic fever (NF) and hospital readmissions continue to pose as the most important limitations in the outpatient setting. It is possible that the febrile episodes may have a non-infectious etiology, and engraftment syndrome could play a more significant role. The aim of this study was to analyze the impact of both G-CSF withdrawal and the addition of primary prophylaxis with corticosteroids after ASCT.. Between January 2002 and August 2018, 111 MM patients conditioned with melphalan were managed at-home beginning +1 day after ASCT. Three groups were established: Group A (n = 33) received standard G-CSF post-ASCT; group B (n = 32) avoided G-CSF post-ASCT; group C (n = 46) avoided G-CSF yet added corticosteroid prophylaxis post-ASCT.. The incidence of NF among the groups was reduced (64%, 44%, and 24%; P<0.001), with a non-significant decrease in hospital readmissions as well (12%, 6%, and 2%; P = 0.07). The most important variables identified for NF were: HCT-CI >2 (OR 6.1; P = 0.002) and G-CSF avoidance plus corticosteroids (OR 0.1; P<0.001); and for hospital readmission: age ≥60 years (OR 14.6; P = 0.04) and G-CSF avoidance plus corticosteroids (OR 0.07; P = 0.05).. G-CSF avoidance and corticosteroid prophylaxis post ASCT minimize the incidence of NF in MM patients undergoing at-home ASCT. This approach should be explored in a prospective randomized clinical trial.

[Autologous haematopoietic stem cell transplantation in patients with multiple myeloma complicated by dialysis-dependent renal failure].
    Terapevticheskii arkhiv, 2020, Sep-01, Volume: 92, Issue:7

    To assess the safety and efficacy of autologous haematopoietic stem cell transplantation (auto-HSCT) in multiple myeloma (MM) patients with dialysis-dependent renal failure.. During a period from May 2010 to December 2016 fourteen MM patients with dialysis-dependent renal failure aged 48 to 65 years underwent auto-HSCT. After the induction therapy complete response, very good partial response, partial response were documented in 64, 29, 7% of patients, respectively. In no case was a renal response achieved. Haematopoietic stem cell mobilization in most patients (13/14) was performed according to the scheme: G-CSF 10 g/kg. Melphalan in 3 dosages was used as pre-transplant conditioning: 100, 140 and 200 mg/m2; 13 patients underwent a single and in one case underwent a tandem auto-HSCT against the background of hemodialysis. Evaluation of the antitumor and renal response was assessed on the 100th day after auto-HSCT. Subsequently, against the background of programmed hemodialysis and in the setting of high-dosed melphalan (100200 mg/m2), 13 patients underwent a single and one patient underwent a tandem auto-HSCT. At +100 days after auto-HSCT, an antitumor response and renal response were assessed.. The period of agranulocytosis after auto-HSCT was from 5 to 12 days (median 8,5) and was accompanied by infectious complications, cardiac and neurological dysfunctions. At +100 days after auto-HSCT, the complete response was confirmed in 71% patients and very good partial response was confirmed in 29% patients. The minimal renal response was registered in 2 patients (14%), hemodialysis was stopped. The transplant-related mortality was absent. After a median follow-up of 53 months 5-year progression-free survival was 59%, and overall survival was 93%.. Carrying out auto-HSCT in patients with dialysis-dependent renal failure contributed to the achievement of a minimal renal response in 14% of cases, which allowed these patients to stop hemodialysis. Patients whose conditioning regimen was performed using melphalan at a dose of 200 mg/m2showed more frequent complications in the early post-transplant period compared to patients who received a lower dose of melphalan (100140 mg/m2). Auto-HSCT in MM patients with dialysis-dependent renal failure is a feasible and effective treatment method, which in some cases contributes to independence from hemodialysis.. Цель.Оценить безопасность и эффективность трансплантации аутологичных стволовых клеток (ауто-ТГСК) крови больным множественной миеломой (ММ) с диализ-зависимой почечной недостаточностью (ПН). Материалы и методы.В ретроспективное исследование включены 14 больных ММ с диализ-зависимой ПН в возрасте от 48 до 65 лет, которым с мая 2010 по август 2018 г. выполнена ауто-ТГСК. После индукционного этапа лечения полная ремиссия, очень хорошая частичная ремиссия, частичная ремиссия документированы у 64, 29, 7% больных соответственно. Ни в одном случае почечный ответ не достигнут. Мобилизация стволовых кроветворных клеток у большинства больных (13/14) проводилась по схеме Г-КСФ 10 мкг/кг. В качестве предтрансплантационного кондиционирования использовался мелфалан в 3 дозировках: 100, 140 и 200 мг/м2; 13 больным выполнена однократная и в одном случае тандемная ауто-ТГСК на фоне программного гемодиализа. Оценка противоопухолевого и почечного ответа проводилась на 100-й день после ауто-ТГСК. Результаты.Период миелотоксического агранулоцитоза после ауто-ТГСК длился от 5 до 12 сут (медиана 8,5 дня) и сопровождался инфекционными эпизодами, кардиальной и неврологической дисфункциями. На +100-й день ауто-ТГСК полная ремиссия диагностирована в 71% случаев, очень хорошая частичная ремиссия у 29% больных. Почечный ответ зарегистрирован у 2 (14%) больных, программный гемодиализ им отменен и возобновления заместительной почечной терапии не потребовалось в течение 24100 мес после ауто-ТГСК. Летальность, связанная с трансплантацией, отсутствовала. При медиане наблюдения 53 мес 5-летняя выживаемость без прогрессии составила 59%, общая выживаемость 93%. Заключение.Проведение ауто-ТГСК больным с диализ-зависимой ПН способствовало достижению минимального почечного ответа в 14% случаев, что позволило прекратить выполнение гемодиализа этим пациентам. У больных, предтрансплантационное кондиционирование которым проведено с применением мелфалана в дозе 200 мг/м2, отмечены более частые осложнения в раннем посттрансплантационном периоде по сравнению с пациентами, получившими меньшую дозу мелфалана (100140 мг/м2). Ауто-ТГСК является эффективным методом лечения больных ММ с диализ-зависимой ПН, в ряде случаев способствующим достижению независимости от гемодиализа.

Kinome expression profiling to target new therapeutic avenues in multiple myeloma.
    Haematologica, 2020, Volume: 105, Issue:3

    Multiple myeloma (MM) account for approximately 10% of hematological malignancies and is the second most common hematological disorder. Kinases inhibitors are widely used and their efficiency for the treatment of cancers has been demonstrated. Here, in order to identify kinases of potential therapeutic interest for the treatment of MM, we investigated the prognostic impact of the kinome expression profile in large cohorts of patients. We identified 36 kinome-related genes significantly linked with a prognostic value to MM, and built a kinome index based on their expression. The Kinome Index (KI) is linked to prognosis, proliferation, differentiation, and relapse in MM. We then tested inhibitors targeting seven of the identified protein kinas-es (PBK, SRPK1, CDC7-DBF4, MELK, CHK1, PLK4, MPS1/TTK) in human myeloma cell lines. All tested inhibitors significantly reduced the viability of myeloma cell lines, and we confirmed the potential clinical interest of three of them on primary myeloma cells from patients. In addition, we demonstrated their ability to potentialize the toxicity of conventional treatments, including Melphalan and Lenalidomide. This highlights their potential beneficial effect in myeloma therapy. Three kinases inhibitors (CHK1i, MELKi and PBKi) overcome resistance to Lenalidomide, while CHK1, PBK and DBF4 inhibitors re-sensitize Melphalan resistant cell line to this conventional therapeutic agent. Altogether, we demonstrate that kinase inhibitors could be of therapeutic interest especially in high-risk myeloma patients defined by the KI. CHEK1, MELK, PLK4, SRPK1, CDC7-DBF4, MPS1/TTK and PBK inhibitors could represent new treatment options either alone or in combination with Melphalan or IMiD for refractory/relapsing myeloma patients.

Impact of frailty, melphalan pharmacokinetics, and pharmacogenetics on outcomes post autologous hematopoietic cell transplantation for multiple myeloma.
    Bone marrow transplantation, 2019, Volume: 54, Issue:12

    Autologous hematopoietic cell transplantation (auto-HCT) using melphalan is the standard of care in the management of myeloma. Auto-HCT is a safe procedure with tolerable toxicity except in Asian-Indians. We hypothesized either one or a combination of factors: (1) frailty (assessed by IMWG frailty score), (2) generic melphalan pharmacokinetic area under the curve (AUC) assessed by high-performance liquid chromatography, and (3) pharmacogenetics of glutathione S-transferase (GSTP1) assessed by Sanger sequencing, to be associated with toxicity and survival outcomes post auto-HCT. Disease response was evaluated by IMWG response criteria at day +100 post auto-HCT. Gastrointestinal (GI) toxicity, infections, hospital stay, progression-free survival (PFS) were also recorded. A total of 35 patients were evaluated over 2 years (2016-2018). Frailty, not HCT-comorbidity index correlated with GI toxicity and infections. Overall there was an 11-fold variation in melphalan AUC with a median of 27.88 mg h/L (10.06-110.26). Patients with AUC more than the median had more GI toxicity and infections. Patients with wild-type GSTP1 polymorphism had more GI toxicity and infections. Frailty, AUC, or GSTP1 polymorphism did not impact hospitalization duration or PFS. A combination of the factors frailty, melphalan pharmacokinetics, and pharmacogenetics impacts GI toxicity and infections after auto-HCT in myeloma.

Extrapolating Survival Data Using Historical Trial-Based a Priori Distributions.
    Value in health : the journal of the International Society for Pharmacoeconomics and Outcomes Research, 2019, Volume: 22, Issue:9

    To show how clinical trial data can be extrapolated using historical trial data-based a priori distributions.. Extrapolations based on 30-month pivotal multiple myeloma trial data were compared with 75-month data from the same trial. The 30-month data represent a typical decision-making scenario where early results from a clinical trial are extrapolated. Mature historical trial data with the same comparator as in the pivotal trial were incorporated in 2 stages. First, the parametric distribution selection was based on the historical trial data. Second, the shape parameter estimate of the historical trial was used to define an informative a priori distribution for the shape of the 30-month pivotal trial data. The method was compared with standard approaches, fitting parametric distributions to the 30-month data with noninformative prior. The predicted survival of each method was compared with the observed survival (ΔAUC) in the 75-month trial data.. The Weibull had the best fit to the historical trial and the log-normal to the 30-month pivotal trial data. The ΔAUC of the Weibull with informative priors was considerably smaller compared with the standard Weibull. Also, the predicted median survival based on the Weibull with informative priors was more accurate (melphalan and prednisone [MP] 40 months, and bortezomib [V] combined with MP [VMP] 62 months) than based on the standard Weibull (MP 45 months and VMP 72 months) when compared with the observed median (MP 41.3 months and VMP 56.4 months).. Extrapolation of clinical trial data is improved by using historical trial data-based informative a priori distributions.

XRCC1-mediated DNA repair is associated with progression-free survival of multiple myeloma patients after autologous stem cell transplant.
    Molecular carcinogenesis, 2019, Volume: 58, Issue:12

    Autologous stem cell transplant (ASCT) with high-dose melphalan (HDM) is the standard treatment for fit multiple myeloma (MM) patients. It is generally believed that some DNA repair proteins impact the activity to repair melphalan-induced DNA damage, thus potentially contributing to the patient's clinical response. However, knowledge of these proteins is limited. In the current study, we investigated the roles of XRCC1, a protein involved in base excision repair and single-strand break repair, in melphalan response in MM cells. Small interfering RNA knockdown of XRCC1 significantly increased the accumulation of melphalan-induced DNA damage in MM cells and sensitized them to melphalan treatment, indicating that genetic variation in XRCC1 may impact response to melphalan treatment. We then evaluated the association between an XRCC1 variant with reduced activity, rs25487 (R399Q), and clinical outcomes of 108 MM patients with melphalan therapy. Our results showed that XRCC1 rs25487 was associated with prolonged progression-free survival (PFS) in MM patients. The adjusted hazard ratio for PFS between patients carrying rs25487 AA/AG and GG was 0.42 (95% confidence interval: 0.25, 0.84, P = .014). Taken together, these results indicate that XRCC1 is involved in the repair of melphalan-induced DNA damage and XRCC1 rs25487 variant with impaired DNA repair function influences the clinical responses of HDM in MM patients.

Circulating monocyte subsets in multiple myeloma patients receiving autologous stem cell transplantation - a study of the preconditioning status and the course until posttransplant reconstitution for a consecutive group of patients.
    BMC immunology, 2019, 11-08, Volume: 20, Issue:1

    Induction therapy of multiple myeloma patients prior to autologous stem cell transplantation has changed from conventional chemotherapy to treatment based on proteasome inhibitors or immunomodulatory drugs. We used flow cytometry to analyze total monocyte and monocyte subset (classical, intermediate and non-classical monocytes) peripheral blood levels before and following auto-transplantation for a consecutive group of myeloma patients who had received the presently used induction therapy.. The patients showed normal total monocyte concentrations after induction/stem cell mobilization, but the concentrations of classical monocytes were increased compared with healthy controls. Melphalan conditioning reduced the levels of total CD14. The total level of circulating monocytes is normalized early after auto-transplantation for multiple myeloma, but pre- and post-transplant levels of various monocyte subsets show considerable variation between patients.

Assessment of TP53 lesions for p53 system functionality and drug resistance in multiple myeloma using an isogenic cell line model.
    Scientific reports, 2019, 12-02, Volume: 9, Issue:1

    Recent advances in molecular diagnostics have shown that lesions affecting both copies of the gene for tumor suppressor protein 53 (TP53) count among the most powerful predictors for high-risk disease in multiple myeloma (MM). However, the functional relevance and potential therapeutic implications of single hits to TP53 remain less well understood. Here, we have for the first time approximated the different constellations of mono- and bi-allelic TP53 lesions observed in MM patients within the frame of a single MM cell line model and assessed their potential to disrupt p53 system functionality and to impart drug resistance. Both types of common first hit: point mutation with expression of mutant p53 protein or complete loss of contribution from one of two wildtype alleles strongly impaired p53 system functionality and increased resistance to melphalan. Second hits abolished remaining p53 activity and increased resistance to genotoxic drugs even further. These results fit well with the clinical drive to TP53 single- and double-hit disease in MM patients, provide a rationale for the most commonly observed double-hit constellation (del17p+ TP53 point mutation), and underscore the potential increases in MM cell malignancy associated with any type of initial TP53 lesion.

Comparable outcomes using propylene glycol-free melphalan for autologous stem cell transplantation in multiple myeloma.
    Bone marrow transplantation, 2019, Volume: 54, Issue:4

    Autologous stem cell transplantation (ASCT) remains a mainstay in the treatment of multiple myeloma (MM). While the procedure is generally safe, toxicities associated with high-dose melphalan conditioning are common and significantly affect patient quality of life. Recently, a propylene glycol-free melphalan formulation (PG-free MEL; Evomela®) was approved by the United States Food and Drug Administration as an ASCT-conditioning regimen for MM. PG-free MEL is more soluble and stable than propylene glycol-solubilized melphalan (PG-solubilized MEL; Alkeran®). As such, there is speculation that it could decrease toxicities and increase the efficacy of ASCT. We compared the outcomes of patients conditioned with PG-free MEL (n = 216) to PG-solubilized MEL (n = 200) at our institution. The baseline characteristics were similar between the two groups. After Day +0, there were no differences in terms of hospitalizations, neutropenic fevers, intravenous granisetron requirement, World Health Organization grade ≥ 2 oral/esophageal mucositis, intravenous fluid requirement, or narcotic requirement. However, PG-free MEL patients had a higher incidence of diarrhea, which was mostly C. difficile-negative (82% vs. 71%, P = 0.015*). Day + 100 hematologic responses and progression-free survival after ASCT were comparable. In summary, we demonstrate that switching to PG-free MEL did not significantly reduce short-term complications of ASCT or improve outcomes in MM.

Evaluating the adverse effects of melphalan formulations.
    Journal of oncology pharmacy practice : official publication of the International Society of Oncology Pharmacy Practitioners, 2019, Volume: 25, Issue:7

    For multiple myeloma patients who respond to primary therapy, autologous hematopoietic stem cell transplant (HSCT) is considered standard of care with high-dose melphalan for transplant candidates. There are now two different melphalan formulations available, including a propylene glycol containing (PG-MEL) product and a propylene glycol-free (PG-free MEL) product. Although considered bioequivalent, there remains limited literature directly evaluating the adverse events between the two agents. We seek to assess the tolerability and severity of side effects between the two formulations in a real-life practice setting.. There were a total of 78 patients who received a melphalan preparation during the study. The median time to myeloablation and neutrophil engraftment was five and seven days post-HSCT, respectively, for all patients. Patients who received PG-free MEL were less likely to develop mucositis, with 22 (56%) reported highest grade 0, defined by World Health Organization oral toxicity scale, compared to those who received PG-MEL (33%), p = 0.04.. There were minimal differences in tolerability or side effects observed between PG-free MEL and PG-MEL. These data may assist in better understanding the anticipated adverse effects of a high-dose melphalan conditioning therapy.

Overexpression of HIF-1α contributes to melphalan resistance in multiple myeloma cells by activation of ERK1/2, Akt, and NF-κB.
    Laboratory investigation; a journal of technical methods and pathology, 2019, Volume: 99, Issue:1

    Multiple myeloma (MM) commonly displays multidrug resistance and is associated with poor prognosis. Therefore, it is important to identify the mechanisms by which MM cells develop multidrug resistance. Our previous study showed that multidrug resistance is correlated with overexpression of multidrug resistance protein 1 (MDR1) and Survivin, and downregulation of Bim expression in melphalan-resistant RPMI8226/L-PAM cells; however, the underlying mechanism of multidrug resistance remains unclear. In the present study, we investigated the mechanism of multidrug resistance in melphalan-resistant cells. We found that RPMI8226/L-PAM and ARH-77/L-PAM cells showed increased phosphorylation of extracellular signal-regulated protein kinase 1/2 (ERK1/2) and Akt, and nuclear localization of nuclear factor κB (NF-κB). The combination of ERK1/2, Akt, and NF-κB inhibitors with melphalan reversed melphalan resistance via suppression of Survivin expression and enhanced Bim expression in melphalan-resistant cells. In addition, RPMI8226/L-PAM and ARH-77/L-PAM cells overexpressed hypoxia-inducible factor 1α (HIF-1α) via activation of ERK1/2, Akt, and NF-κB. Moreover, suppression of HIF-1α by echinomycin or HIF-1α siRNA resensitized RPMI8226/L-PAM cells to melphalan through downregulation of Survivin expression and upregulation of Bim expression. These results indicate that enhanced Survivin expression and decreased Bim expression by HIF-1α via activation of ERK1/2, Akt, and NF-κB play a critical role in melphalan resistance. Our findings suggest that HIF-1α, ERK1/2, Akt, and NF-κB inhibitors are potentially useful as anti-MDR agents for the treatment of melphalan-resistant MM.

Modified dose of melphalan-prednisone in multiple myeloma patients receiving bortezomib plus melphalan-prednisone treatment.
    The Korean journal of internal medicine, 2019, Volume: 34, Issue:6

    Bortezomib plus melphalan-prednisone (VMP) is a standard treatment for multiple myeloma, particularly for patients who are ineligible for high-dose therapy. However, early discontinuation or treatment modification is often needed owing to adverse events. The aim of this study was to investigate the clinical outcomes of modifying the dose of melphalan-prednisone (MP) in patients receiving VMP.. We examined 67 patients who received a modified dose of MP, and 38 patients who received the regularly planned dose of MP. We then analyzed clinical differences between the groups.. Although there was no difference in the proportion of discontinuation due to adverse events between dose groups, more patients in the planned-dose group experienced earlier discontinuation in general. The overall response rate (ORR) was 81.0% and complete response (CR) rate was 30.5%. After a median 15.7 months of follow-up, the median progression-free survival (PFS) and overall survival (OS) were 25.0 and 47.8 months, respectively. There was no significant difference in the ORR, CR, PFS, and OS of the two dose groups. A median of four cycles were delivered, and the median cumulative bortezomib dose was 41.6 mg/m2 . The median PFS in patients with doses ≥ 41.6 mg/m2 was longer than that in patients with doses < 41.6 mg/m2 (35.1 months vs. 9.6 months). However, when MP was < 50% of the planned dose, PFS and OS were poor.. Modifying the dose of MP might be a feasible and effective therapeutic approach for multiple myeloma patients receiving VMP treatment.

Impact of increased access to novel agents on the survival of multiple myeloma patients treated at a single New Zealand centre.
    Internal medicine journal, 2019, Volume: 49, Issue:5

    The impact of changes in novel agent (NA) usage on the survival of multiple myeloma (MM) patients in real-world hospital settings is unclear. In New Zealand (NZ) in 2011, frontline bortezomib became available and thalidomide availability was expanded.. This retrospective study analyses the impact these change had on the survival of MM patients treated at a NZ hospital.. Clinical and overall survival (OS) data were collected on MM patients who were treated at Christchurch Hospital during 2000-2009 (pre-cohort, n = 337) and 2011-2017 (post-cohort, n = 343). Outcomes were compared using pre-cohort data truncated at 2011.. Patients in the post-cohort had significant increases (P < 0.001) in not only NA usage (85 vs 55%) and OS (median = 56 vs 44 months) but also the proportion (74 vs 49%) of young patients (age < 70) who received an autologous stem cell transplant (ASCT). Separate analysis of older patients demonstrated that those in the post-cohort had significantly longer OS (median OS 28 vs 17, P < 0.001) although 5-year relative survival remained less than 50%. Separate analysis of young patients demonstrated that those in the post-cohort had significantly increased initial OS with the survival curves converging at 5 years. Although ASCT-treated patients had similar OS in each cohort, their progression-free survival (PFS) was significantly increased in the post-cohort (median 40 vs 20 months, P < 0.0001).. In the setting of a NZ hospital the increased availability of NA was associated with a significant improvement in both the OS of older patients and the PFS of ASCT patients.

Elucidating the beneficial effects of melphalan, adriamycin, and corticoids in combination with bortezomib against multiple myeloma in vitro.
    Naunyn-Schmiedeberg's archives of pharmacology, 2019, Volume: 392, Issue:4

    Combining bortezomib with other anti-cancer drugs or glucocorticoids is more efficient in multiple myeloma than bortezomib alone. However, the molecular mechanism of this beneficial effect is largely unknown. To investigate the effects of these compounds on bortezomib's anti-proliferative potency and its intracellular accumulation and potency to inhibit the chymotrypsin-like proteasomal subunit, seven myeloma cell lines were investigated after exposure to bortezomib alone or either combined with adriamycin plus dexamethasone (PAD regimen) or melphalan plus prednisolone (VMP regimen), respectively. PAD or VMP combinations did not alter cellular bortezomib uptake. However, PAD and VMP regimens increased bortezomib's chymotrypsin-like subunit inhibitory potency. This likely originates from indirect proteasome modulation, because adriamycin, dexamethasone, melphalan, or prednisolone did not inhibit this subunit when used alone. Strikingly, the anti-proliferative potency of bortezomib was not enhanced but slightly lowered in some cell lines when used in combinations. Adriamycin, dexamethasone, melphalan, or prednisolone can enhance bortezomib's chymotrypsin-like subunit inhibitory potency, likely by mechanisms indirectly influencing proteasome functionality.

A Single Nucleotide Polymorphism in
    Anticancer research, 2019, Volume: 39, Issue:1

    SLC7A5 is recognized as the major mediator of melphalan uptake into multiple myeloma (MM) cells; however, its contribution to the inter-patient variability of melphalan efficacy and toxicity is yet to be well elucidated. This study aimed to investigate the impact of a single nucleotide polymorphism (SNP) rs4240803 in SLC7A5 on the gene expression, ex vivo sensitivity to melphalan, and clinical outcomes in MM patients who were undergoing autologous stem cell transplantation with high-dose melphalan.. Peripheral blood mononuclear cells (PBMC) were collected from 108 MM patients prior to melphalan therapy. Clinical data were also collected from these patients following melphalan therapy.. rs4240803 was associated with elevated expression of SLC7A5 mRNA, higher ex vivo sensitivity to melphalan in PBMCs, and positive 90-day response in these patients (p=0.047, 0.10, 0.049, respectively).. rs4240803 impacted the expression of SLC7A5, thus contributing to the clinical response of MM patients to melphalan therapy.

Dose Adjustment Helps Obtain Better Outcomes in Multiple Myeloma Patients with Bortezomib, Melphalan, and Prednisolone (VMP) Treatment
    Turkish journal of haematology : official journal of Turkish Society of Haematology, 2019, 05-03, Volume: 36, Issue:2

    Multiple myeloma (MM) has a better survival outcome because of the development of drugs. However, equivalent outcomes cannot be expected from the same drug. Therefore, how the treatment schedule is managed is important. We analyzed VMP (bortezomib, melphalan, and prednisolone) data to determine an effective treatment strategy.. We collected the data of 59 patients who were newly diagnosed with MM from January 2012 to April 2017 using electronic medical records. We analyzed baseline characteristics, responses, dose reductions, and survival.. The overall response rate was 86.5% [complete response (CR): 32.2%, very good partial response (VGPR): 37.3%]. The median progression-free survival was 33.6 months and the 5-year overall survival rate was 70%. There were significant better progression-free survival outcomes between CR and non-CR for each of the 4 cycles. Of the four patients who achieved CR after the first cycle, none have had disease progression as of yet. We divided patients into two groups according to the median dose (52.1 mg/m. Active dose reduction helped to continue treatment and it increased the opportunity to be exposed to drugs. In the end, it resulted in improved outcome.. Günümüzde yeni geliştirilen ilaçlar sayesinde multiple myelom (MM) hastalarında tedavi sonuçları daha iyidir. Ancak, aynı ilaç için her hastada eşit sonuçlar elde edilmesi beklenemez. Bu nedenle, tedavi şemalarının nasıl düzenlendiği büyük önem taşımaktadır. Biz VMP (bortezomib, melfalan ve prednizolon) tedavi verilerini etkin tedavi stratejisi belirlemek amacıyla inceledik.. Ocak 2012’den Nisan 2017’ye kadar yeni tanı almış 59 MM hastalarının elektronik dosyaları incelendi. Tedavi öncesi özellikler, tedavi cevapları, doz azaltımları ve sağkalımları analiz edildi.. Tüm yanıt oranı %86,5 [tam yanıt (TY) %32,2; çok iyi parsiyel yanıt %37,3) idi. Medyan progresyonsuz yaşam 33,6 ay ve 5 yıllık genel sağkalım %70 idi. Her 4 siklus için de TY sağlanan hastalarda medyan progresyonsuz yaşam TY sağlanamayan hastalara göre istatistiksel olarak anlamlı düzeyde daha iyiydi. İlk siklus sonrasında TY sağlanmış olan 4 hastanın hiçbirinde şu ana kadar progresyon izlenmedi. Hastaları median doza göre (52,1 mg/m. Aktif doz azaltılması, tedavinin devamının sağlanmasına yardım etmekte ve ilaçlara maruziyetinin artmasına fırsat tanımaktadır. Sonuç olarak da daha iyi tedavi sonuçları sağlamaktadır.

Proteometabolomics of Melphalan Resistance in Multiple Myeloma.
    Methods in molecular biology (Clifton, N.J.), 2019, Volume: 1996

    Drug resistance remains a critical problem for the treatment of multiple myeloma (MM), which can serve as a specific example for a highly prevalent unmet medical need across almost all cancer types. In MM, the therapeutic arsenal has expanded and diversified, yet we still lack in-depth molecular understanding of drug mechanisms of action and cellular pathways to therapeutic escape. For those reasons, preclinical models of drug resistance are developed and characterized using different approaches to gain insights into tumor biology and elucidate mechanisms of drug resistance. For MM, numerous drugs are used for treatment, including conventional chemotherapies (e.g., melphalan or L-phenylalanine nitrogen mustard), proteasome inhibitors (e.g., Bortezomib), and immunomodulators (e.g., Lenalidomide). These agents have diverse effects on the myeloma cells, and several mechanisms of drug resistance have been previously described. The disparity of these mechanisms and the complexity of these biological processes lead to the formation of complicated hypotheses that require omics approaches for efficient and effective analysis of model systems that can then be interpreted for patient benefit. Here, we describe the combination of metabolomics and proteomics to assess melphalan resistance in MM by examining three specific areas: drug metabolism, modulation of endogenous metabolites to assist in therapeutic escape, and changes in protein activity gauged by ATP probe uptake.

Therapeutic effects of CSF1R-blocking antibodies in multiple myeloma.
    Leukemia, 2018, Volume: 32, Issue:1

    Our previous studies showed that macrophages (MФs), especially myeloma-associated MФs (MAMs), induce chemoresistance in human myeloma. Here we explored the potential of targeting MФs, by using colony-stimulating factor 1 receptor (CSF1R)-blocking mAbs, to treat myeloma. Our results showed that CSF1R blockade specifically inhibited the differentiation, proliferation and survival of murine M2 MФs and MAMs, and repolarized MAMs towards M1-like MФs in vitro. CSF1R blockade alone inhibited myeloma growth in vivo, by partially depleting MAMs, polarizing MAMs to the M1 phenotype, and inducing a tumor-specific cytotoxic CD4

Chemotherapy induces secretion of exosomes loaded with heparanase that degrades extracellular matrix and impacts tumor and host cell behavior.
    Matrix biology : journal of the International Society for Matrix Biology, 2018, Volume: 65

    The heparan sulfate-degrading enzyme heparanase promotes the progression of many cancers by driving tumor cell proliferation, metastasis and angiogenesis. Heparanase accomplishes this via multiple mechanisms including its recently described effect on enhancing biogenesis of tumor exosomes. Because we recently discovered that heparanase expression is upregulated in myeloma cells that survive chemotherapy, we were prompted to investigate the impact of anti-myeloma drugs on exosome biogenesis. When myeloma cells were exposed to the commonly utilized anti-myeloma drugs bortezomib, carfilzomib or melphalan, exosome secretion by the cells was dramatically enhanced. These chemotherapy-induced exosomes (chemoexosomes) have a proteome profile distinct from cells not exposed to drug including a dramatic elevation in the level of heparanase present as exosome cargo. The chemoexosome heparanase was not found inside the chemoexosome, but was present on the exosome surface where it was capable of degrading heparan sulfate embedded within an extracellular matrix. When exposed to myeloma cells, chemoexosomes transferred their heparanase cargo to those cells, enhancing their heparan sulfate degrading activity and leading to activation of ERK signaling and an increase in shedding of the syndecan-1 proteoglycan. Exposure of chemoexosomes to macrophages enhanced their secretion of TNF-α, an important myeloma growth factor. Moreover, chemoexosomes stimulated macrophage migration and this effect was blocked by H1023, a monoclonal antibody that inhibits heparanase enzymatic activity. These data suggest that anti-myeloma therapy ignites a burst of exosomes having a high level of heparanase that remodels extracellular matrix and alters tumor and host cell behaviors that likely contribute to chemoresistance and eventual patient relapse.. We find that anti-myeloma chemotherapy dramatically stimulates secretion of exosomes and alters exosome composition. Exosomes secreted during therapy contain high levels of heparanase on their surface that can degrade ECM and also can be transferred to both tumor and host cells, altering their behavior in ways that may enhance tumor survival and progression.

Symptom experience of multiple myeloma (syMMex) patients treated with autologous stem cell transplantation following high-dose melphalan: a descriptive longitudinal study.
    Supportive care in cancer : official journal of the Multinational Association of Supportive Care in Cancer, 2018, Volume: 26, Issue:3

    High-dose melphalan and autologous stem cell transplantation (ASCT) are associated with high symptom burden. This study aimed to explore multiple myeloma (MM) patients' experience of symptom frequency, intensity, and distress during therapy.. This descriptive longitudinal study enrolled 29 MM patients who completed the 43-item PROVIVO questionnaire, measuring symptom experience across the dimensions of frequency, intensity, and distress at four assessment points: hospital admission (T0), leucocyte nadir (T1), discharge (T2), and 30 days post discharge (T3). Symptom assessment covered five categories: (1) physical, (2) emotional, (3) cognitive, (4) male/female urogenital symptoms, and (5) follow-up care planning (e.g., financial problems). Results were displayed as heat maps and bubble graphs for each patient, differences between T0 and T4 individually assessed, and intensity (IMS) and mean distress scores (DMS) calculated on a scale from 0 to 4.. The most frequent, intense, and distressing physical symptoms were fatigue, diarrhea, and decreased appetite. As expected, peak symptom intensity (decreased appetite 2.79) and distress (diarrhea 2.11) were reported during high-dose melphalan and the leucocyte nadir (T1). Thereafter, most symptoms' intensity and distress improved. Items on urogenital symptoms remained predominantly unanswered or patients were sexually inactive.. PROVIVO enabled exploration of various dimensions of MM patients' symptom experiences, which differed substantially before and after ASCT. Our results suggest that high-dose melphalan, ASCT, and other intensive novel agent therapies warrant targeted symptom management programs that include focused patient support.

The MIP-1α autocrine loop contributes to decreased sensitivity to anticancer drugs.
    Journal of cellular physiology, 2018, Volume: 233, Issue:5

    Several autocrine soluble factors, including macrophage inflammatory protein-1α (MIP-1α), tumor necrosis factor-α, and hepatocyte growth factor, promote cell survival and growth in multiple myeloma (MM) cells. We hypothesized that inhibition of the MIP-1α autocrine loop may enhance the cytotoxic effect of anticancer drugs in MM cell lines. In the present study, an MIP-1α neutralizing antibody suppressed cell proliferation and enhanced the cytotoxic effect of melphalan or bortezomib on MM cells. In addition, melphalan resistance cells (RPMI8226/L-PAM and HS-sultan/L-PAM cells) secreted MIP-1α and neutralizing antibody of MIP-1α partially overcame melphalan resistance. Moreover, combination treatment with MIP-1α neutralizing antibody and melphalan or bortezomib inhibited extracellular signal regulated kinase 1/2 (ERK1/2), Akt, and mammalian target of rapamycin (mTOR) activation, Bcl-2, Bcl-xL, and Survivin expression, and upregulated the expression of Bim and cleaved Poly (ADP-ribose) polymerase (PARP). Treatment of IM9 cells with MIP-1α siRNA suppressed the activation of ERK1/2, Akt, and mTOR, and enhanced the cytotoxic effect of melphalan and bortezomib. These results indicate that MIP-1α neutralizing antibodies or MIP-1α siRNA enhance the cytotoxic effect of melphalan and bortezomib by suppressing the chemokine receptor/ERK and chemokine receptor/Akt/mTOR pathways. The inhibition of MIP-1α may thus provide a new therapeutic approach to control tumor progression and bone destruction in patients with MM.

Impact of Dose-Adjusted Melphalan in Obese Patients Undergoing Autologous Stem Cell Transplantation.
    Biology of blood and marrow transplantation : journal of the American Society for Blood and Marrow Transplantation, 2018, Volume: 24, Issue:4

    Limited guidance exists for dosing melphalan for autologous stem cell transplantation (ASCT) in the obese patient population, because the current literature reports conflicting clinical outcomes between obese and nonobese patients. In 2014, the American Society for Blood and Marrow Transplantation published conditioning chemotherapy dosing guidelines for obese patients and recommended dosing of melphalan using actual body weight (ABW) in the body surface area calculation. The practice at Barnes-Jewish Hospital has consistently been to dose melphalan using adjusted body weight (AdBW), with a 20% correction when a patient weighs ≥120% of his or her ideal body weight (IBW). The purpose of this study was to compare outcomes of melphalan ASCT in patients with multiple myeloma between obese (≥120% IBW) and nonobese (<120% IBW) populations. This retrospective, single-center study included adult patients with multiple myeloma undergoing first ASCT with melphalan conditioning between January 2009 and December 2012. Patient demographic data, transplantation characteristics, and clinical outcomes were collected. The primary outcome was 3-year event-free survival (EFS). Secondary outcomes included response at 100 days post-transplantation, 3-year overall survival, treatment-related mortality (TRM), time to neutrophil engraftment, and hospital length of stay (LOS). To ensure that melphalan dosage adjustment in the obese population did not impact efficacy, the primary outcome was assessed using a noninferiority design, with a predetermined noninferiority margin of 7%. Assuming a 70% 3-year EFS in the nonobese population, a noninferiority margin of 7%, a power of 80%, and an α value of .05, an analysis of 280 patients was required. A total of 270 patients, including 171 (63%) obese patients and 99 (37%) nonobese patients, met our inclusion criteria. Baseline characteristics were well matched between the 2 cohorts, including high-risk cytogenetics, disease severity at diagnosis, and use of maintenance therapy, with the only detectable differences related to weight itself. The 3-year EFS was 41% for the total cohort, with fewer events occurring in the obese cohort compared with the nonobese cohort (51% versus 40%; P = .0025). The 95% lower confidence limit established noninferiority. High-risk cytogenetics, disease severity at diagnosis, and therapy response pre- and post-ASCT were all associated with significantly shorter EFS. No between-group differences in TRM, time to

Comparison of conditioning regimen toxicities among autologous stem cell transplantation eligible multiple myeloma patients: High-dose melphalan versus high-dose melphalan and bortezomib.
    Journal of oncology pharmacy practice : official publication of the International Society of Oncology Pharmacy Practitioners, 2018, Volume: 24, Issue:4

    Background Autologous hematopoietic stem cell transplantation (AHSCT) remains the standard of care for younger patients with multiple myeloma (MM). Currently, high-dose melphalan (HDM) is recommended as conditioning regimen before AHSCT. Preclinical data suggest that combining bortezomib and melphalan has synergistic effect against multiple myeloma cells. Bortezomib and HDM (Bor-HDM) combination as conditioning regimen has been investigated by many other investigators. Objective In this retrospective study, we aimed to compare transplant-related toxicities and hematologic recovery of HDM and Bor-HDM conditioning regimens. Method We retrospectively evaluated hematologic recovery and toxicity profile in patients with MM who received AHSCT with either HDM ( n = 114) or Bor-HDM ( n = 53) conditioning regimen. Results Nonhematologic toxicities were comparable between HDM and Bor-HDM conditioning regimen, except mucositis and diarrhea being more frequent in the Bor-HDM group. Neutrophil and platelet engraftment time and duration of hospital stay were significantly shorter for HDM regimen. Conclusions In this retrospective analysis, we observed engraftment kinetics and duration of hospitalization were significantly worse in Bor-HDM conditioning regimen with manageable toxicities. Randomized studies are needed to further compare Bor- HDM regimen to HDM in terms of response rates, toxicities, and transplant-related mortality.

Amifostine reduces gastro-intestinal toxicity after autologous transplantation for multiple myeloma.
    Leukemia & lymphoma, 2018, Volume: 59, Issue:8

    High-dose melphalan (HDM) followed by autologous hematopoietic cell transplantation (auto-HCT) remains the standard-of-care therapy for multiple myeloma (MM) even with the availability of proteasome inhibitors and immunomodulatory drugs. Gastrointestinal (GI) toxicity is the main cause of morbidity after HDM. Amifostine, a cytoprotective agent, may reduce HDM-associated GI toxicity. We conducted a case control study comparing HDM + auto-HCT with or without amifostine for MM patients. One hundred and seven patients treated at University Hospitals Cleveland Medical Center who received pre-transplant amifostine were compared to 114 patients treated at MD Anderson Cancer Center without use of this agent. Amifostine 740 mg/m

Comparison of two melphalan protocols and evaluation of outcome and prognostic factors in multiple myeloma in dogs.
    Journal of veterinary internal medicine, 2018, Volume: 32, Issue:3

    Multiple myeloma (MM) in dogs typically is treated with melphalan. A daily melphalan dosing schedule reportedly is well tolerated and associated with favorable outcome. Although anecdotally a pulse dose regimen has resulted in successful responses, little long-term outcome and safety data is available regarding this dosing regimen for dogs with MM.. (1) To compare outcome and adverse event profiles between pulse dose and daily dose melphalan schedules and (2) to report prognostic factors in dogs with MM treated with melphalan. We hypothesized that both protocols would have similar outcomes and tolerability.. Thirty-eight client-owned dogs diagnosed with MM receiving pulse dose (n = 17) or daily dose (n = 21) melphalan.. Retrospective cohort study assessing outcome and adverse events in dogs receiving either protocol. Risk factors were evaluated for their prognostic relevance.. Both regimens were well tolerated and similarly effective, with an overall median survival time of 930 days. Renal disease and neutrophil-to-lymphocyte ratio (NLR) were negative prognostic factors, whereas hypercalcemia and osteolytic lesions were not prognostic factors in this study population.. Positive results support the use of either dosing regimen for the treatment of dogs with MM, and renal disease and NLR were negative prognostic factors. Prospective, controlled, and randomized studies are warranted to confirm these findings.

[Development of a standardized guide for optimizing drug adherence information to be dispensed during a pharmaceutical counseling with a multiple myeloma patient: Initial validation].
    Bulletin du cancer, 2018, Volume: 105, Issue:5

    The safety of the community treatment with oral anticancer therapies is a strong theme of the cancer plan 2014-2019. The objective of this study was to develop a Pharmaceutical Counseling Guide to improve medication adherence in patients treated for multiple myeloma with oral anticancer therapies. A multidisciplinary professional working group selected a list of relevant medication adherence-related items that served as the framework for the design of the pharmaceutical counseling support materials in patient-accessible language. The readability, understanding and memorization of the information were validated in ten patients treated for myeloma. Twelve items were selected for treatment information (5 items), treatment planning (5 items), and adverse drug effects (2 items). A pharmacist guide, a patient guide, a medication schedule, and three self-questionnaires to evaluate medication knowledge and understanding of patients were developed. The patient test resulted in changes in these documents. This study carried out the initial validation of documents to standardize the pharmaceutical counseling for patients treated for myeloma so that it can be reproduced from one patient to another regardless of the pharmacist, by standardizing the information issued. This study needs to be completed by a final validation in myeloma patients, free from oral anticancer therapies.

Early salivary changes in multiple myeloma patients undergoing autologous HSCT.
    Oral diseases, 2018, Volume: 24, Issue:6

    One explorative observational study in two parts was performed to examine early salivary changes in relation to oral mucositis (OM) in multiple myeloma patients treated with high-dose melphalan and autologous haematopoietic stem cell transplantation (HSCT). As cryotherapy was introduced after part A as regular care, its effect on OM could be evaluated.. Unstimulated whole-mouth saliva (UWS) and stimulated whole-mouth saliva (SWS) were collected, and OM was scored with the Oral Mucositis Nursing Instrument (OMNI) at days -3, 0, 4, 7, 11 and 14 after HSCT. Salivary flow rate, total protein (BCA), mucin 5B, albumin (western blot), total IgA, lactoferrin and myeloperoxidase levels (ELISA) were determined.. Trends of decreasing UWS and SWS flow rates and total IgA levels were observed. At days 7 and 11, increases in lactoferrin and albumin levels were found in UWS and SWS. A positive correlation was found between OMNI scores and albumin and lactoferrin levels in SWS (R. Compositional changes in saliva reflecting inflammation were found in the first days after HSCT, and the use of cryotherapy in the second part was associated with decreased OM severity.

Autologous stem cell transplantation in first remission is associated with better progression-free survival in multiple myeloma.
    Annals of hematology, 2018, Volume: 97, Issue:10

    Autologous stem cell transplant (ASCT) is standard consolidation therapy in management of multiple myeloma (MM) patients. We reviewed records of all consecutive MM patients who underwent ASCT with high-dose melphalan at our center from year 2002 to 2016. A total of 141 ASCT were conducted (90 males and 51 females) with median age of 55 years (23-68 years). Median time from diagnosis to transplant was 7 months (3-79), with majority of patients underwent transplant in first remission, while 17 (12%) patients received transplant beyond first remission. Eighty-three percent patients obtained CR/VGPR post-ASCT. Transplant-related mortality was 2.1%. At a median follow up of 54 months, mean overall survival (OS) and progression-free survival (PFS) group were 128.3 months (95% C.I. 111.9-144.7 months) and 73.8 months (95% C.I. 57.7-89.9 months), respectively. On univariate analysis, OS was adversely affected by renal insufficiency (p = 0.024), while OS was better with CR/VGPR post-ASCT (p < 0.001) and lenalidomide maintenance therapy (p = 0.009). PFS was affected by CR/VGPR pre-ASCT (p = 0.021), CR/VGPR post-ASCT (p < 0.001), and transplant in first remission (p = 0.034). On multivariate analysis, lenalidomide maintenance (versus thalidomide) (p = 0.007) and CR/VGPR response post-ASCT (p = 0.0003) were found to be predictors for better OS and CR/VGPR response at transplant for better PFS (p = 0.038). Transplant in first remission versus beyond first remission showed a trend for better PFS (p = 0.073).. Majority of patients obtained CR/VGPR post-ASCT. Longer PFS was seen with patients who were transplanted in first remission.

    The purpose of our experiments was to investigate the targeting relationship of linc00515, miR-140-5p and ATG14 and to explore the roles of linc00515, miR-140-5p and ATG14 in autophagy and chemoresistance of melphalan-resistant multiple myeloma cells.. Plasmids that could interfere with the expression of linc00515 and ATG14 were loaded into myeloma cells, which were cultured with melphalan. MTT assay and flow cytometry analysis were utilized to investigate the effect of linc00515, miR-140-5p and ATG14 on the resistance of myeloma cells. QRT-PCR was used to determine the levels of mRNAs. Western blot was utilized to explore the level of ATG14 and autophagy-related proteins. Dual luciferase assay was utilized to explore the targeting relationship between linc00515, miR-140-5p and ATG14. GFP LC3 fluorescence assay was conducted to study the autophagy of cells.. The expression of linc00515 and ATG14 were significantly higher in melphalan-resistant myeloma cells. Knockdown of linc00515 and ATG14 led to decreased autophagy and chemoresistance of melphalan-resistant myeloma cells. The forced expression of miR-140-5p suppressed autophagy and chemoresistance of melphalan-resistant myeloma cells.. Linc00515 enhanced autophagy and chemoresistance of melphalan-resistant myeloma by directly inhibiting miR-140-5p, which elevated ATG14 level.

Role of apurinic/apyrimidinic nucleases in the regulation of homologous recombination in myeloma: mechanisms and translational significance.
    Blood cancer journal, 2018, 09-25, Volume: 8, Issue:10

    We have previously reported that homologous recombination (HR) is dysregulated in multiple myeloma (MM) and contributes to genomic instability and development of drug resistance. We now demonstrate that base excision repair (BER) associated apurinic/apyrimidinic (AP) nucleases (APEX1 and APEX2) contribute to regulation of HR in MM cells. Transgenic as well as chemical inhibition of APEX1 and/or APEX2 inhibits HR activity in MM cells, whereas the overexpression of either nuclease in normal human cells, increases HR activity. Regulation of HR by AP nucleases could be attributed, at least in part, to their ability to regulate recombinase (RAD51) expression. We also show that both nucleases interact with major HR regulators and that APEX1 is involved in P73-mediated regulation of RAD51 expression in MM cells. Consistent with the role in HR, we also show that AP-knockdown or treatment with inhibitor of AP nuclease activity increases sensitivity of MM cells to melphalan and PARP inhibitor. Importantly, although inhibition of AP nuclease activity increases cytotoxicity, it reduces genomic instability caused by melphalan. In summary, we show that APEX1 and APEX2, major BER proteins, also contribute to regulation of HR in MM. These data provide basis for potential use of AP nuclease inhibitors in combination with chemotherapeutics such as melphalan for synergistic cytotoxicity in MM.

Pharmacokinetic-Pharmacodynamic Model of Neutropenia in Patients With Myeloma Receiving High-Dose Melphalan for Autologous Stem Cell Transplant.
    CPT: pharmacometrics & systems pharmacology, 2018, Volume: 7, Issue:11

    High-dose melphalan (HDM) is part of the conditioning regimen in patients with multiple myeloma (MM) receiving autologous stem cell transplantation (ASCT). However, individual sensitivity to melphalan varies, and many patients experience severe toxicities. Prolonged severe neutropenia is one of the most severe toxicities and contributes to potentially life-threatening infections and failure of ASCT. Granulocyte-colony stimulating factor (G-CSF) is given to stimulate neutrophil proliferation after melphalan administration. The aim of this study was to develop a population pharmacokinetic/pharmacodynamic (PK/PD) model capable of predicting neutrophil kinetics in individual patients with MM undergoing ASCT with high-dose melphalan and G-CSF administration. The extended PK/PD model incorporated several covariates, including G-CSF regimen, stem cell dose, hematocrit, sex, creatinine clearance, p53 fold change, and race. The resulting model explained portions of interindividual variability in melphalan exposure, therapeutic effect, and feedback regulation of G-CSF on neutrophils, thus enabling simulation of various doses and prediction of neutropenia duration.

Pharmacokinetics and Exposure-Response Analyses of Daratumumab in Combination Therapy Regimens for Patients with Multiple Myeloma.
    Advances in therapy, 2018, Volume: 35, Issue:11

    Daratumumab, a human IgG monoclonal antibody targeting CD38, has demonstrated activity as monotherapy and in combination with standard-of-care regimens in multiple myeloma. Population pharmacokinetic analyses were conducted to determine the pharmacokinetics of intravenous daratumumab in combination therapy versus monotherapy, evaluate the effect of patient- and disease-related covariates on drug disposition, and examine the relationships between daratumumab exposure and efficacy/safety outcomes.. Four clinical studies of daratumumab in combination with lenalidomide/dexamethasone (POLLUX and GEN503); bortezomib/dexamethasone (CASTOR); pomalidomide/dexamethasone, bortezomib/thalidomide/dexamethasone, and bortezomib/melphalan/prednisone (EQUULEUS) were included in the analysis. Using various dosing schedules, the majority of patients (684/694) received daratumumab at a dose of 16 mg/kg. In GEN503, daratumumab was administered at a dose of 2 mg/kg (n = 3), 4 mg/kg (n = 3), 8 mg/kg (n = 4), and 16 mg/kg (n = 34). A total of 650 patients in EQUULEUS (n = 128), POLLUX (n = 282), and CASTOR (n = 240) received daratumumab 16 mg/kg. The exposure-efficacy and exposure-safety relationships examined progression-free survival (PFS) and selected adverse events (infusion-related reactions; thrombocytopenia, anemia, neutropenia, lymphopenia, and infections), respectively.. Pharmacokinetic profiles of daratumumab were similar between monotherapy and combination therapy. Covariate analysis identified no clinically important effects on daratumumab exposure, and no dose adjustments were recommended on the basis of these factors. Maximal clinical benefit on PFS was achieved for the majority of patients (approximately 75%) at the 16 mg/kg dose. No apparent relationship was observed between daratumumab exposure and selected adverse events.. These data support the recommended 16 mg/kg dose of daratumumab and the respective dosing schedules in the POLLUX and CASTOR pivotal studies.. Janssen Research & Development.

Clinical outcomes of bortezomib-based therapy in myeloma.
    PloS one, 2018, Volume: 13, Issue:12

    Bortezomib, a first generation proteasome inhibitor, is used in both newly diagnosed and relapsed myeloma settings. Considerable differences exist in the usage of bortezomib therapy in the clinical practice setting in comparison to clinical trial setting as well manufacturer's recommendations. These differences include route of administration (intravenous (iv) vs. subcutaneous (sc)), frequency from twice to once weekly, choice of alkylating agent used in combination with bortezomib (melphalan or cyclophosphamide), and choice of glucocorticoids (dexamethasone or prednisolone). We reviewed data from 272 consecutive bortezomib-treated myeloma patients, who received therapy within the regional Thames Valley Cancer Network for both newly diagnosed myeloma (NDMM, n = 120) and relapsed MM (RMM, n = 152). We investigated the influence of age, sex, transplant, bortezomib combinations (doublet vs. triplet), cumulative bortezomib dose per treatment line (<50mg vs. ≥50mg), and route of administration (iv vs. sc) on time to next treatment (TTNT) and on overall survival (OS). Route of bortezomib administration (iv vs. sc) influenced neither OS (41 vs 35 months, p = 0.5), nor TTNT (14 vs. 19 months, p = 0.052). Our study showed a statistically significant improvement in median OS in patients receiving a cumulative dose ≥50mg compared to <50mg (42 vs. 33months, p = 0.003), although presence of confounders need to be taken into account, such as disease stage, performance status, genetic changes and prior therapies. Median OS was longer using triplet therapies compared to a doublet in the RMM cohort (37 vs. 29 months, p = 0.06), although this did not reach statistical significance. Multivariate Cox Regression analysis showed that cumulative bortezomib dose ≥50mg (p = 0.002, HR = 1.83, 95% CI 1.25-2.67) and autologous transplant (p = 0.002, HR = 2.6, 95% CI 1.41-3.98) were both significant factors associated with improved OS. Our data argues in favour of continuing bortezomib for the recommended duration as per Summary of Product Characteristics (SPC), subject to good tolerability, in order to deepen response or extend the duration of best response.

Long-term follow-up of patients with multiple myeloma treated with total body irradiation-Melphalan conditioning.
    European journal of haematology, 2017, Volume: 99, Issue:1

    Since a study published in 2002 showed a survival advantage of melphalan-only conditioning for stem cell transplantation (HSCT) over melphalan-total body irradiation (mel-TBI) in patients with multiple myeloma (MM), most centers abandoned mel-TBI. Mel-TBI causes more early toxicity and is more complicated to administer, but we speculated it may result in longer term survival with radiation as an independent treatment modality. Therefore, we analyzed the long-term outcome of patients with MM who received mel-TBI as part of conditioning at our center.. From 1995 to 2013, 50 patients with MM underwent autologous HSCT at Tulane University Medical Center using mel-TBI conditioning. We used Kaplan-Meier survival analysis and compared our patients with data available from the Louisiana Tumor Registry.. The mean survival of our patients was 70.98 months from time of transplant and 84.2 months from time of initial diagnosis. No differences were observed according to gender, ethnicity, or age at transplant. The expected median survival in a population-based registry (matched for age and year of treatment) was 27 months (P<.001).. Total body irradiation in conjunction with melphalan as conditioning is feasible and can lead to long-term survival. More research is necessary to determine which patients benefit most. Mel-TBI should also be explored in conjunction with immunotherapy.

Autologous Stem Cell Transplantation in Multiple Myeloma in the Era of Novel Drug Induction: A Retrospective Single-Center Analysis.
    Acta haematologica, 2017, Volume: 137, Issue:3

    Within this retrospective single-center study, we analyzed the survival of 320 multiple myeloma (MM) patients receiving melphalan high-dose chemotherapy (HDCT) and either single (n = 286) or tandem (n = 34) autologous stem cell transplantation (ASCT) from 1996 to 2012. Additionally, the impact of novel induction regimens was assessed. Median follow-up was 67 months, median overall survival (OS) 62 months, median progression-free survival (PFS) 33 months (95% CI 27-39), and treatment-related death (TRD) 3%. Multivariate analysis revealed age ≥60 years (p = 0.03) and stage 3 according to the International Staging System (p = 0.006) as adverse risk factors regarding PFS. Median OS was significantly better in newly diagnosed MM patients receiving induction therapy with novel agents, e.g., bortezomib, thalidomide, or lenalidomide, compared with a traditional regimen (69 vs. 58 months; p = 0.01). More patients achieved at least a very good partial remission in the period from 2005 to 2012 than from 1996 to 2004 (65 vs. 30%; p < 0.001), with a longer median OS in the later period (71 vs. 52 months, p = 0.027). In conclusion, our analysis confirms HDCT-ASCT as an effective therapeutic strategy in an unselected large myeloma patient cohort with a low TRD rate and improved prognosis due to novel induction strategies.

A prospective, open-label, multicenter, observational study to evaluate the efficacy and safety of bortezomib-melphalan-prednisone as initial treatment for autologous stem cell transplantation-ineligible patients with multiple myeloma.
    Oncotarget, 2017, Jun-06, Volume: 8, Issue:23

    Bortezomib-melphalan-prednisone (VMP) showed superior efficacy versus MP as first-line treatment for transplantation-ineligible multiple myeloma (MM). This study investigated the efficacy of VMP for Korean patients with MM.Overall, 177 MM patients received 9 cycles of VMP in this prospective, multicenter, observational study. The primary endpoint was 2-year progression-free survival (PFS).Thirty-nine (22%) patients were aged ≥ 75 years and 83 (47.4%) patients had International Staging System stage III. A median of 5 cycles were delivered. Overall response rate (ORR) was 72.9%, and complete response (CR) rate was 20.3%. With a median follow-up of 11.9 months, median PFS was 17 months. The 2-year PFS and overall survival (OS) rates were 29.2% and 80.0%, respectively. Median OS was not reached. PFS was significantly different depending on performance status (Eastern Cooperative Oncology Group < 2 vs. ≥ 2; p = 0.0002), β2-microglobulin level (< 5.5 vs. ≥ 5.5 mg/L; p = 0.0481), and cumulative dose of bortezomib (< 35.1 vs. ≥ 35.1 mg/m2; p < 0001). The common adverse events (AEs) were in line with the well-known toxicity profiles associated with VMP.In conclusion, VMP is a feasible and effective front-line treatment for transplant-ineligible older patients with MM in Korea. Continuing therapy with prompt adjustment of treatment according to AEs may be important to improve outcomes of elderly patients.

The impact of comorbidity on mortality in multiple myeloma: a Danish nationwide population-based study.
    Cancer medicine, 2017, Volume: 6, Issue:7

    To describe the prevalence of comorbidity and its impact on survival in newly diagnosed multiple myeloma patients compared with population controls. Cases of newly diagnosed symptomatic multiple myeloma during the 2005-2012 period were identified in the Danish National Multiple Myeloma Registry. For each myeloma patient, 10 members of the general population matched by age and sex were chosen from the national Civil Registration System. Data on comorbidity in the myeloma patients and the general population comparison cohort were collected by linkage to the Danish National Patient Registry (DNPR). Cox proportional hazards regression models were used to evaluate the prognostic significance of comorbidity. The study included 2190 cases of multiple myeloma and 21,900 population controls. The comorbidity was increased in multiple myeloma patients compared with population controls, odds ratio (OR) 1.4 (1.1-1.7). The registration of comorbidity was highly increased within the year preceding diagnosis of multiple myeloma (OR 3.0 [2.5-3.5]), which was attributable to an increased registration of various diseases, in particular, renal disease with OR 11.0 (8.1-14.9). The median follow-up time from diagnosis of multiple myeloma for patients alive was 4.3 years (interquartile range 2.4-6.3). Patients with registered comorbidity had increased mortality compared with patients without comorbidity, hazard ratio 1.6 (1.5-1.8). Multiple myeloma patients have increased comorbidity compared with the background population, in particular during the year preceding the diagnosis of myeloma.

Olanzapine Reduces Chemotherapy-induced Nausea and Vomiting Compared With Aprepitant in Myeloma Patients Receiving High-dose Melphalan Before Stem Cell Transplantation: A Retrospective Study.
    Clinical lymphoma, myeloma & leukemia, 2017, Volume: 17, Issue:9

    Acute and delayed chemotherapy-induced nausea and vomiting (CINV) occurs in most patients who receive high-dose melphalan and significantly affects patients' quality of life during autologous stem cell transplantation. Faced with unsatisfactory results using an aprepitant-based regimen, an olanzapine-based regimen was initiated, with the hope of improving the incidence of acute and delayed CINV. A retrospective study was conducted to compare the effectiveness of olanzapine- versus aprepitant-based regimens for CINV prevention in adult hematopoietic stem cell recipients who received high-dose melphalan.. We compared olanzapine (n = 43) to aprepitant (n = 54) and fosaprepitant (n = 20). Olanzapine was given orally at 5 mg twice daily for 5 days, aprepitant was given at 125 mg on day -1 and 80 mg on days 0 and 1, and fosaprepitant was given at 150 mg on day -1. The dose of 2 concomitant drugs (dexamethasone and 5-hydroxytryptamine type 3 receptor antagonist) was similar in the 2 groups. Nausea prevention was the primary endpoint. A complete response using a composite index of no emesis and no use of rescue medications was the secondary endpoint.. The results showed that olanzapine significantly reduced the number of patients who experienced acute (P < .0001) or delayed (P < .004) nausea and significantly reduced the use of rescue medications for acute-onset (P < .0046) and delayed-onset (P < .0001) CINV compared with aprepitant.. Compared with fosaprepitant, olanzapine reduced the number of patients with acute (P < .0318) and delayed (P < .1519) nausea and reduced the need for rescue medications for acute-onset (P < .0643) and delayed-onset (P < .0024) CINV.

Prognostic value of sequencing-based minimal residual disease detection in patients with multiple myeloma who underwent autologous stem-cell transplantation.
    Annals of oncology : official journal of the European Society for Medical Oncology, 2017, Oct-01, Volume: 28, Issue:10

    Most patients with multiple myeloma (MM) are considered to be incurable, and relapse owing to minimal residual disease (MRD) is the main cause of death among these patients. Therefore, new technologies to assess deeper response are required.. We retrospectively analyzed 125 patients with MM who underwent high-dose melphalan plus autologous stem-cell transplantation (ASCT) to detect MRD in autograft/bone marrow (BM) cells using a next-generation sequencing (NGS)-based method and allele-specific oligonucleotide-polymerase chain reaction (ASO-PCR).. NGS-based method was applicable to 90% and this method had at least one to two logs greater sensitivity compared to ASO-PCR. MRD negative by NGS [MRDNGS(-)] (defined as <10-6) in post-ASCT BM cases (n = 26) showed a significantly better progression-free survival (PFS) (96% at 4 years, P < 0.001) and overall survival (OS) (100% at 4 years, P =0.04) than MRDNGS(+) in post-ASCT BM cases (n = 25). When restricting the analysis to the 39 complete response cases, patients who were MRDNGS(-) (n = 24) showed a significantly better PFS than those that were MRDNGS(+) (n = 15) (P =0.02). Moreover, MRDNGS(-) in post-ASCT BM cases (n = 12) showed significantly a better PFS than MRDNGS(+) cases (n = 7) where MRD was not detected by ASO-PCR (P = 0.001). Patients whose autografts were negative by NGS-based MRD assessment (<10-7) (n = 19) had 92% PFS and 100% OS at 4 years post-ASCT. Conversely, the NGS-based MRD positive patients who received post-ASCT treatment using novel agents (n = 49) had a significantly better PFS (P = 0.001) and tended to have a better OS (P= 0.214) than those that were untreated (n = 33).. Low level MRD detected by NGS-based platform but not ASO-PCR has significant prognostic value when assessing either the autograft product or BM cells post-ASCT.

Constitutional mutation in CDKN2A is associated with long term survivorship in multiple myeloma: a case report.
    BMC cancer, 2017, Nov-06, Volume: 17, Issue:1

    Multiple Myeloma is a cancer of plasma cells associated with significantly reduced survival. Long term survivorship from myeloma is very rare and despite advances in its treatment the disease is generally considered incurable. We report a patient diagnosed with myeloma carrying a germline mutation of a tumour suppressor gene who has effectively been cured.. A 36-year-old woman was diagnosed with IgG lambda myeloma in 1985. She was treated with melphalan chemotherapy followed by high-dose melphalan and autologous stem cell rescue and since remained in complete remission despite not having received any additional therapy. After eliciting a prior history of multiple primary melanomas and breast cancer, she was tested for and shown to be a carrier for a germline mutation in CDKN2A.. This is the second case report of germline mutation of CDKN2A being associated with myeloma. CDKN2A is a stabiliser of p53. Long term survivorship after high dose DNA damaging chemotherapy with melphalan in this patient is compatible with an increased chemo-sensitivity due to impairment of the DNA repair pathway.

[Diagnostic and evolutionary profile of multiple myeloma in Senegal: monocentric study conducted from 2005 to 2016].
    The Pan African medical journal, 2017, Volume: 27

    Accessibility to innovative multiple myeloma therapies is limited in sub-Saharan Africa. This study aimed to describe the diagnostic and evolutionary features observed during treatment of our patients with myeloma.. We conducted a retrospective, descriptive, analytical study (2005 - 2016) of patients with myeloma included in the study based on International Myeloma Working Group (IMWG) Criteria (2003,2014) at the Hopital Aristide Le Dantec (Senegal).. We collected data from 136 medical records (69 men, 67 women) of patients with an average age of 59 years ± 10.1 years, who were less than 65 years of age in 69.1% of cases. Tell-tale signs included bone pain (96.3%), renal failure (36.8%), infection (23.5%), pathological fracture (17.6%), spinal cord compression (16.9%) and malignant hypercalcaemia (16.2%). Isotopic antiglobulin test showed that anti-IgG could be detected in 61.3% of cases and Kappa in 65% of cases. Patients were classified stage III (59.4%) and I-II (40.6%)of the index staging system. The median survival of patients under conventional traitement (Méphalan-Prédnisone: 67.6%, innovative: 5.9%) was 20 months (1-78 months). Survival rates are better in the absence of neurological and infectious complications and for patients with score I-II of the index Staging System.. In our study, multiple myeloma was frequently diagnosed before age 65, at advanced stage of tumor mass. Early detection and access to adequate therapies could improve overall survival.

Encephalopathy following melphalan administration.
    Journal of chemotherapy (Florence, Italy), 2017, Volume: 29, Issue:1

    To describe a rare case of encephalopathy following melphalan administration. Presentation and intervention:: A 59-year-old female with multiple myeloma developed encephalopathy following administration of melphalan. After ruling out other aetiologies, we hypothesized elevated cytokines from systemic inflammatory response to melphalan as the likely aetiology. The TNF-alpha level was found to be significantly elevated. Plasmapharesis was performed which reduced the level of cytokines, and also improved the patient's neurological status.. Melphalan administration, especially in renally impaired patients, may lead to development of encephalopathy. Based on our case report, we suggest that elevated levels of cytokines could be the underlying mechanism of worsening mental status.

Icing oral mucositis: Oral cryotherapy in multiple myeloma patients undergoing autologous hematopoietic stem cell transplant.
    Journal of oncology pharmacy practice : official publication of the International Society of Oncology Pharmacy Practitioners, 2017, Volume: 23, Issue:2

    Background Up to 70% of patients receiving hematopoietic stem cell transplant develop oral mucositis as a side effect of high-dose melphalan conditioning chemotherapy. Oral cryotherapy has been documented to be potentially effective in reducing oral mucositis. The aim of this study was to examine the effectiveness of the cryotherapy protocol implemented within the hematopoietic stem cell transplant program. Methods A retrospective chart review was conducted of adult multiple myeloma patients who received high-dose melphalan conditioning therapy for autologous hematopoietic stem cell transplant. Primary endpoints were incidence and severity of oral mucositis. Secondary endpoints included duration of oral mucositis, duration of hospital stay, parenteral narcotics use and total parenteral nutrition use. Results One hundred and forty patients were included in the study, 70 patients in both no cryotherapy and cryotherapy groups. Both oral mucositis incidence and severity were found to be significantly lower in the cryotherapy group. Fifty (71.4%) experienced mucositis post cryotherapy compared to 67 (95.7%) in the no cryotherapy group (p < 0.001). The median oral mucositis severity, assessed using the WHO oral toxicity scale from grade 0-4, experienced in the no group was 2.5 vs. 2 in the cryotherapy group (p = 0.03). Oral mucositis duration and use of parenteral narcotics were also significantly reduced. Duration of hospital stay and use of parenteral nutrition were similar between the two groups. Conclusion The cryotherapy protocol resulted in a significantly lower incidence and severity of oral mucositis. These results provide evidence for the continued use of oral cryotherapy, an inexpensive and generally well-tolerated practice.

Mixed outpatient-inpatient autologous stem cell transplant for multiple myeloma: A cost-saving initiative in a resource constrained environment.
    Journal of oncology pharmacy practice : official publication of the International Society of Oncology Pharmacy Practitioners, 2017, Volume: 23, Issue:5

    Background Although administration of chemotherapy prior to autologous stem cell transplantation in the outpatient setting has been reported as safe and cost-effective, many limitations exist with previously reported methods of transitioning out of the hospital ward. Specifically, lack of a caregiver and distance from treatment facility are key factors particularly in rural settings. Given these limitations, not all institutions have transitioned the transplant process, or even portions of it, to the outpatient setting despite the known benefits. Methods To achieve financial benefit without compromising safety, a novel mixed outpatient-inpatient model was adopted at our institution. Eligible patients receive melphalan in the clinic the day prior to being admitted for peripheral blood stem cell re-infusion where they remain until recovery of myelosuppression. Results In the year since implementation, nineteen total patients received high-dose melphalan prior to autologous stem cell transplantation. Eighteen of these patients successfully received melphalan in the outpatient clinic with admission to the hospital on day zero for infusion of stem cells. No patient experienced any adverse event on the day or evening of chemotherapy or required early admission. The average estimated total reduction in cost per patient to the institution was over US$2,000. When comparing the cost of the chemotherapy drug, melphalan, from the year before and the year after implementation of the mixed model the total annual cost saving was approximately US$90,00 or 53% of the previous year's expenditure. Conclusions The implementation of this mixed outpatient-inpatient model was safe, feasible, and cost-effective.

Complete remission of skin lesions in a patient with subcorneal pustular dermatosis (Sneddon-Wilkinson disease) treated with antimyeloma therapy: association with disappearance of M-protein.
    The British journal of dermatology, 2017, Volume: 176, Issue:5

    Subcorneal pustular dermatosis (SPD), or Sneddon-Wilkinson disease, is a rare pustular skin disease that follows a chronic relapsing course. A well-known association exists between SPD and IgA monoclonal gammopathy of undetermined significance (MGUS), which exists in up to 40% of cases. SPD has also been observed in patients with IgA myeloma. In SPD, direct and indirect immunofluorescence studies do not reveal in vivo bound IgA to the epithelial cell surface, in contrast to IgA pemphigus, which has similar clinicopathological features. Here we describe the case of a male patient with SPD and a concurrent IgA MGUS who had been treated with dapsone for 20 years with frequent relapses. Following development of multiple myeloma, the patient was treated with intensive antimyeloma treatment consisting of high-dose melphalan with autologous stem cell transplantation. This resulted in a complete remission of the myeloma with disappearance of the M-protein. In addition, a sustained remission of SPD was achieved without further treatment. Twenty-eight months after melphalan therapy the M-protein reappeared in the serum, and 2 months later SPD reappeared with histopathologically proven skin lesions at predilection sites. Presence and absence of skin lesions was found to correlate with the presence and absence of the M-protein in the serum. This is the first report of antimyeloma therapy inducing a long-lasting remission in SPD. The findings in this patient strongly suggest a causal role for circulating IgA antibodies in the pathogenesis of SPD. Antimyeloma treatment should be considered in patients with IgA MGUS-associated SPD refractory to other therapies.

Therapeutic experience of vincristine/cyclophosphamide/melphalan or mitoxantrone/prednisone combination therapy plus thalidomide as first-line induction therapy for newly diagnosed multiple myeloma in a single institution of China.
    Asia-Pacific journal of clinical oncology, 2017, Volume: 13, Issue:5

    To investigate the safety and efficacy of the combination regimen vincristine, cyclophosphamide, melphalan or mitoxantrone and prednisone (VCMP) plus thalidomide as first-line induction therapy for newly diagnosed multiple myeloma (MM).. Three hundred and ninety-six symptomatic, newly diagnosed MM patients were treated with VCMP plus thalidomide in our hospital for the past 11 years, and clinical data of these patients were retrospectively analyzed.. Of the 396 patients enrolled, the total response rate was 77.3%. Forty-three patients relapsed after sCR and CR. Mean cycles to first response were six cycles (range 1-16 cycles). A total of 53% of patients achieved at least a PR within the first cycle of therapy. The actuarial 1-year, 3-year and 5-year overall survival of all patients were 89.4%, 29.5% and 10.6%, respectively. The probabilities of 1-year, 3-year and 5-year progression-free survival of all patients were 84.0%, 23.1% and 8.4%, respectively. The major adverse events were gastrointestinal symptoms, electrolytes and glucose metabolism disorders, hypertension, infection, peripheral nerve disease and hematological adverse events, which were mostly below grade 3 and could be alleviated by symptomatic treatment.. We concluded that VCMP plus thalidomide is an effective regimen with manageable side effects in the treatment of symptomatic, newly diagnosed MM including elderly patients and patients with renal failure.

Efficacy and toxicity of the combination chemotherapy of thalidomide, alkylating agent, and steroid for relapsed/refractory myeloma patients: a report from the Korean Multiple Myeloma Working Party (KMMWP) retrospective study.
    Cancer medicine, 2017, Volume: 6, Issue:1

    We analyzed the treatment responses, toxicities, and survival outcomes of patients with relapsed or refractory multiple myeloma who received daily thalidomide, cyclophosphamide, and dexamethasone (CTD) or daily thalidomide, melphalan, and prednisolone (MTP) at 17 medical centers in Korea. Three-hundred and seventy-six patients were enrolled. The combined chemotherapy of thalidomide, corticosteroid, and an alkylating agent (TAS) was second-line chemotherapy in 142 (37.8%) patients, and third-line chemotherapy in 135 (35.9%) patients. The response rate overall was 69.4%. Patients who were not treated with bortezomib and lenalidomide before TAS showed a higher response rate compared to those who were exposed to these agents. The estimated median progression-free survival and overall survival times were 10.4 months and 28.0 months, respectively. The adverse events during TAS were generally tolerable, but 39 (10.4%) patients experienced severe infectious complications. There were no differences in terms of efficacy between CTD and MTP, but infectious complications were more common in CTD group. TAS is an effective treatment regimen which induces a high response rate in relapsed or refractory multiple myeloma patients. Due to the high incidence of grade 3 or 4 infection, proper management of infection is necessary during the TAS treatment, especially the CTD.

Molecular Characteristics of High-Dose Melphalan Associated Oral Mucositis in Patients with Multiple Myeloma: A Gene Expression Study on Human Mucosa.
    PloS one, 2017, Volume: 12, Issue:1

    Toxicity of the oral and gastrointestinal mucosa induced by high-dose melphalan is a clinical challenge with no documented prophylactic interventions or predictive tests. The aim of this study was to describe molecular changes in human oral mucosa and to identify biomarkers correlated with the grade of clinical mucositis.. Ten patients with multiple myeloma (MM) were included. For each patient, we acquired three buccal biopsies, one before, one at 2 days, and one at 20 days after high-dose melphalan administration. We also acquired buccal biopsies from 10 healthy individuals that served as controls. We analyzed the biopsies for global gene expression and performed an immunohistochemical analysis to determine HLA-DRB5 expression. We evaluated associations between clinical mucositis and gene expression profiles. Compared to gene expression levels before and 20 days after therapy, at two days after melphalan treatment, we found gene regulation in the p53 and TNF pathways (MDM2, INPPD5, TIGAR), which favored anti-apoptotic defense, and upregulation of immunoregulatory genes (TREM2, LAMP3) in mucosal dendritic cells. This upregulation was independent of clinical mucositis. HLA-DRB1 and HLA-DRB5 (surface receptors on dendritic cells) were expressed at low levels in all patients with MM, in the subgroup of patients with ulcerative mucositis (UM), and in controls; in contrast, the subgroup with low-grade mucositis (NM) displayed 5-6 fold increases in HLA-DRB1 and HLA-DRB5 expression in the first two biopsies, independent of melphalan treatment. Moreover, different splice variants of HLA-DRB1 were expressed in the UM and NM subgroups.. Our results revealed that, among patients with MM, immunoregulatory genes and genes involved in defense against apoptosis were affected immediately after melphalan administration, independent of the presence of clinical mucositis. Furthermore, our results suggested that the expression levels of HLA-DRB1 and HLA-DRB5 may serve as potential predictive biomarkers for mucositis severity.

Polymorphism in ANRIL is associated with relapse in patients with multiple myeloma after autologous stem cell transplant.
    Molecular carcinogenesis, 2017, Volume: 56, Issue:7

    Multiple myeloma (MM) is a hematologic malignancy characterized by clonal proliferation of plasma cells and overproduction of monoclonal immunoglobins. Treatment with melphalan is currently standard of care for younger and fit patients when followed by hematopoietic stem cell transplantation (HSCT), and in transplant ineligible patients when used in combination regimens. It has been previously shown that changes in the p53 pathway are associated with melphalan efficacy, but the regulatory role of the p14ARF-MDM2-p53 axis has yet to be fully explored. Recently, a non-coding RNA, ANRIL (antisense non-coding RNA in the INK4-ARF locus) has been shown to negatively regulate the transcription of the entire INK4-ARF locus and simultaneously modulate the p53 and pRb pathways. Moreover, some single nucleotide polymorphisms (SNPs) in ANRIL have previously been associated with susceptibility to several malignancies. Here we investigated select ANRIL SNPs in DNA from patient-derived peripheral blood mononuclear cells obtained from 108 MM patients treated with high-dose melphalan followed by HSCT. Our results show that the rs2151280 (CàT) SNP in ANRIL was associated with worse progression-free survival (TC/CC vs TT: HR = 0.53, 95%CI, [0.26, 1.07], P = 0.07; adjusted HR = 0.39, 95%CI, [0.18, 0.84], P = 0.016), and the TT variant had higher ANRIL expression and lower p15, p14ARF, and p16 expression compared to the TC/CC variants. Our results indicate that ANRIL may be involved in melphalan-mediated apoptosis via down-regulating p14ARF and subsequent p53, and that the rs2151280 polymorphism may be a potential prognostic biomarker for relapse in melphalan-treated MM patients.

Autologous Hematopoietic Cell Transplantation in Patients With Multiple Myeloma: Effect of Age.
    Clinical lymphoma, myeloma & leukemia, 2017, Volume: 17, Issue:3

    In the novel and pre-novel agent era, high-dose therapy, followed by autologous hematopoietic cell transplantation (AHCT), has been shown to prolong survival in patients with multiple myeloma (MM) in randomized trials. However, these trials only included patients aged ≤ 65 years. Given that the median age at diagnosis is 66 years, it is important to know the outcomes of AHCT in older patients. Similarly, definite outcomes of AHCT in very young patients (aged < 50 years) are also lacking because they represent a very small proportion of patients in clinical trials.. We analyzed a consecutive cohort of patients with MM receiving AHCT from 2000 to 2015 in 2 different age groups, older (> 70 years) and younger (≤ 50 years), and compared the outcomes. The primary objectives were to assess overall survival, progression-free survival (PFS), and nonrelapse mortality in these 2 groups.. Of the 191 patients, 86 were young (age ≤ 50 years) and 105 were old (age > 70 years). The younger patients had better performance status and a lower comorbidity index, and most of the older patients had received a melphalan dose of 140 to 180 mg/m. Age should not be a limiting factor in considering the modality of AHCT. However, younger patients might also benefit from additional novel treatment approaches in the setting of clinical trials, given their similar outcomes with the older patients in our study.

RECQ1 helicase is involved in replication stress survival and drug resistance in multiple myeloma.
    Leukemia, 2017, Volume: 31, Issue:10

    Multiple myeloma (MM) is a plasma cell cancer with poor survival, characterized by the expansion of multiple myeloma cells (MMCs) in the bone marrow. Using a microarray-based genome-wide screen for genes responding to DNA methyltransferases (DNMT) inhibition in MM cells, we identified RECQ1 among the most downregulated genes. RecQ helicases are DNA unwinding enzymes involved in the maintenance of chromosome stability. Here we show that RECQ1 is significantly overexpressed in MMCs compared to normal plasma cells and that increased RECQ1 expression is associated with poor prognosis in three independent cohorts of patients. Interestingly, RECQ1 knockdown inhibits cells growth and induces apoptosis in MMCs. Moreover, RECQ1 depletion promotes the development of DNA double-strand breaks, as evidenced by the formation of 53BP1 foci and the phosphorylation of ataxia-telangiectasia mutated (ATM) and histone variant H2A.X (H2AX). In contrast, RECQ1 overexpression protects MMCs from melphalan and bortezomib cytotoxicity. RECQ1 interacts with PARP1 in MMCs exposed to treatment and RECQ1 depletion sensitizes MMCs to poly(ADP-ribose) polymerase (PARP) inhibitor. DNMT inhibitor treatment results in RECQ1 downregulation through miR-203 deregulation in MMC. Altogether, these data suggest that association of DNA damaging agents and/or PARP inhibitors with DNMT inhibitors may represent a therapeutic approach in patients with high RECQ1 expression associated with a poor prognosis.

Prognostic role of circulating exosomal miRNAs in multiple myeloma.
    Blood, 2017, 04-27, Volume: 129, Issue:17

    Exosomes, secreted by several cell types, including cancer cells, can be isolated from the peripheral blood and have been shown to be powerful markers of disease progression in cancer. In this study, we examined the prognostic significance of circulating exosomal microRNAs (miRNAs) in multiple myeloma (MM). A cohort of 156 patients with newly diagnosed MM, uniformly treated and followed, was studied. Circulating exosomal miRNAs were isolated and used to perform a small RNA sequencing analysis on 10 samples and a quantitative reverse transcription polymerase chain reaction (qRT-PCR) array on 156 samples. We studied the relationship between miRNA levels and patient outcomes, including progression-free survival (PFS) and overall survival (OS). We identified miRNAs as the most predominant small RNAs present in exosomes isolated from the serum of patients with MM and healthy controls by small RNA sequencing of circulating exosomes. We then analyzed exosomes isolated from serum samples of 156 patients using a qRT-PCR array for 22 miRNAs. Two of these miRNAs, let-7b and miR-18a, were significantly associated with both PFS and OS in the univariate analysis and were still statistically significant after adjusting for the International Staging System and adverse cytogenetics in the multivariate analysis. Our findings support the use of circulating exosomal miRNAs to improve the identification of patients with newly diagnosed MM with poor outcomes. The results require further validation in other independent prospective MM cohorts.

High-dose chemotherapy and autologous stem cell transplantation of patients with multiple myeloma in an outpatient setting.
    BMC cancer, 2017, 02-22, Volume: 17, Issue:1

    High-dose (HD) chemotherapy with melphalan and autologous blood stem cell transplantation (ABSCT) for treatment of symptomatic multiple myeloma (MM) on an outpatient basis has been well established in the USA and Canada, whereas in Germany and Western Europe an inpatient setting is the current standard. We report on a German single-centre program to offer the procedure on an outpatient basis to selected patients.. Major requirements included: patients had to have family and/or other caregivers, had to be able to reach the hospital within 45 min and have an ECOG performance score of 0-1. Patients with severe co-morbidities were not included.. From September 2012 until April 2016, 21 patients with MM stage IIIA were enrolled. All engrafted within the expected time range (median 14 days), and no severe adverse events occurred. 14 patients (67%) had an episode of neutropenic fever and blood cultures were positive in 4 patients (19%). Although rather liberal criteria for hospital admission were applied, 14 patients (67%) were treated entirely on an outpatient basis.. HD chemotherapy and ABSCT on an outpatient basis is safe and feasible if it is conducted in an elaborate surveillance program. The feedback from patients was very positive, thus encouraging further expansion of the program.

Multiple Myeloma Tumor Cells are Selectively Killed by Pharmacologically-dosed Ascorbic Acid.
    EBioMedicine, 2017, Volume: 18

    High-dose chemotherapies to treat multiple myeloma (MM) can be life-threatening due to toxicities to normal cells and there is a need to target only tumor cells and/or lower standard drug dosage without losing efficacy. We show that pharmacologically-dosed ascorbic acid (PAA), in the presence of iron, leads to the formation of highly reactive oxygen species (ROS) resulting in cell death. PAA selectively kills CD138

Impact of cytogenetic classification on outcomes following early high-dose therapy in multiple myeloma.
    Leukemia, 2016, Volume: 30, Issue:3

    Early high-dose therapy (HDT), consisting of high-dose melphalan and autologous stem cell transplantation following doublet or triplet novel agent induction, is a preferred management strategy for transplant-eligible myeloma patients. We set out to examine the utility of the current fluorescence in situ hybridization (FISH)-based risk stratification in a homogenously treated population of transplant-eligible myeloma patients receiving novel induction regimens and early HDT with or without posttransplant maintenance therapy. FISH was available in 409 patients at the time of diagnosis for patients receiving HDT within 12 months of diagnosis. We present comprehensive outcomes for chromosome 14 translocations and 17p abnormalities that both support and refute current risk stratification models. In contrast to its current classification as a marker of 'standard risk' (SR), t(11;14) was associated with inferior overall survival (OS) when compared with the classical SR cohort. The use of novel agent maintenance therapy (bortezomib or lenalidomide) following early HDT ameliorates the negative prognostic value of high-risk (HR) cytogenetic markers. HR patients who received maintenance following early HDT had similar OS compared with the SR cohort at 5 years.

Cost-effectiveness of lenalidomide plus dexamethasone vs. bortezomib plus melphalan and prednisone in transplant-ineligible U.S. patients with newly-diagnosed multiple myeloma.
    Journal of medical economics, 2016, Volume: 19, Issue:3

    To conduct a cost-effectiveness assessment of lenalidomide plus dexamethasone (Rd) vs bortezomib plus melphalan and prednisone (VMP) as initial treatment for transplant-ineligible patients with newly-diagnosed multiple myeloma (MM), from a U.S. payer perspective.. A partitioned survival model was developed to estimate expected life-years (LYs), quality-adjusted LYs (QALYs), direct costs and incremental costs per QALY and LY gained associated with use of Rd vs VMP over a patient's lifetime. Information on the efficacy and safety of Rd and VMP was based on data from multinational phase III clinical trials and a network meta-analysis. Pre-progression direct costs included the costs of Rd and VMP, treatment of adverse events (including prophylaxis) and routine care and monitoring associated with MM. Post-progression direct costs included costs of subsequent treatment(s) and routine care and monitoring for progressive disease, all obtained from published literature and estimated from a U.S. payer perspective. Utilities were obtained from the aforementioned trials. Costs and outcomes were discounted at 3% annually.. Relative to VMP, use of Rd was expected to result in an additional 2.22 LYs and 1.47 QALYs (discounted). Patients initiated with Rd were expected to incur an additional $78,977 in mean lifetime direct costs (discounted) vs those initiated with VMP. The incremental costs per QALY and per LY gained with Rd vs VMP were $53,826 and $35,552, respectively. In sensitivity analyses, results were found to be most sensitive to differences in survival associated with Rd vs VMP, the cost of lenalidomide and the discount rate applied to effectiveness outcomes.. Rd was expected to result in greater LYs and QALYs compared with VMP, with similar overall costs per LY for each regimen. Results of this analysis indicated that Rd may be a cost-effective alternative to VMP as initial treatment for transplant-ineligible patients with MM, with an incremental cost-effectiveness ratio well within the levels for recent advancements in oncology.

A 13 mer LNA-i-miR-221 Inhibitor Restores Drug Sensitivity in Melphalan-Refractory Multiple Myeloma Cells.
    Clinical cancer research : an official journal of the American Association for Cancer Research, 2016, Mar-01, Volume: 22, Issue:5

    The onset of drug resistance is a major cause of treatment failure in multiple myeloma. Although increasing evidence is defining the role of miRNAs in mediating drug resistance, their potential activity as drug-sensitizing agents has not yet been investigated in multiple myeloma.. Here we studied the potential utility of miR-221/222 inhibition in sensitizing refractory multiple myeloma cells to melphalan.. miR-221/222 expression inversely correlated with melphalan sensitivity of multiple myeloma cells. Inhibition of miR-221/222 overcame melphalan resistance and triggered apoptosis of multiple myeloma cells in vitro, in the presence or absence of human bone marrow (BM) stromal cells. Decreased multiple myeloma cell growth induced by inhibition of miR-221/222 plus melphalan was associated with a marked upregulation of pro-apoptotic BBC3/PUMA protein, a miR-221/222 target, as well as with modulation of drug influx-efflux transporters SLC7A5/LAT1 and the ABC transporter ABCC1/MRP1. Finally, in vivo treatment of SCID/NOD mice bearing human melphalan-refractory multiple myeloma xenografts with systemic locked nucleic acid (LNA) inhibitors of miR-221 (LNA-i-miR-221) plus melphalan overcame drug resistance, evidenced by growth inhibition with significant antitumor effects together with modulation of PUMA and ABCC1 in tumors retrieved from treated mice.. Taken together, our findings provide the proof of concept that LNA-i-miR-221 can reverse melphalan resistance in preclinical models of multiple myeloma, providing the framework for clinical trials to overcome drug resistance, and improve patient outcome in multiple myeloma.

Bone marrow PMN-MDSCs and neutrophils are functionally similar in protection of multiple myeloma from chemotherapy.
    Cancer letters, 2016, Feb-01, Volume: 371, Issue:1

    Multiple myeloma (MM) is an incurable cancer of plasma cells localized preferentially in the bone marrow (BM). Resistance to chemotherapy represents one of the main challenges in MM management. BM microenvironment is known to play a critical role in protection of MM cells from chemotherapeutics; however, mechanisms responsible for this effect are largely unknown. Development of MM is associated with accumulation of myeloid-derived suppressor cells (MDSCs) mostly represented by pathologically activated relatively immature polymorphonuclear neutrophils (PMN-MDSCs). Here, we investigated whether PMN-MDSCs are responsible for BM microenvironment-mediated MM chemoresistance. Using in vivo mouse models allowing manipulation of myeloid cell number, we demonstrated a critical role for myeloid cells in MM growth and chemoresistance. PMN-MDSCs isolated from MM-bearing host are immunosuppressive and thus, functionally distinct from their counterpart in tumor-free host neutrophils. We found, however, that both PMN-MDSCs and neutrophils equally promote MM survival from doxorubicin and melphalan and that this effect is mediated by soluble factors rather than direct cell-cell contact. Our data indicate that targeting PMN-MDSCs would enhance chemotherapy efficacy in MM.

Dexamethasone treatment promotes Bcl-2 dependence in multiple myeloma resulting in sensitivity to venetoclax.
    Leukemia, 2016, Volume: 30, Issue:5

    Venetoclax (ABT-199), a specific inhibitor of the anti-apoptotic protein Bcl-2, is currently in phase I clinical trials for multiple myeloma. The results suggest that venetoclax is only active in a small cohort of patients therefore we wanted to determine its efficacy when used in combination. Combining venetoclax with melphalan or carfilzomib produced additive or better cell death in four of the five cell lines tested. The most striking results were seen with dexamethasone (Dex). Co-treatment of human myeloma cell lines and primary patient samples, with Dex and venetoclax, significantly increased cell death over venetoclax alone in four of the five cell lines, and in all patient samples tested. The mechanism by which this occurs is an increase in the expression of both Bcl-2 and Bim upon addition of Dex. This results in alterations in Bim binding to anti-apoptotic proteins. Dex shifts Bim binding towards Bcl-2 resulting in increased sensitivity to venetoclax. These data suggest that knowledge of drug-induced alterations of Bim-binding patterns may help inform better combination drug regimens. Furthermore, the data indicate combining this novel therapeutic with Dex could be an effective therapy for a broader range of patients than would be predicted by single-agent activity.

Inhibiting the anaphase promoting complex/cyclosome induces a metaphase arrest and cell death in multiple myeloma cells.
    Oncotarget, 2016, Jan-26, Volume: 7, Issue:4

    The anaphase promoting complex/cyclosome (APC/C) is an ubiquitin ligase involved in cell cycle. During the metaphase-anaphase transition the APC/C is activated by Cdc20. The aim of this study is to elucidate the importance and therapeutic potential of APC/C and its co-activator Cdc20 in multiple myeloma (MM). Gene expression analysis revealed that Cdc20 was expressed at higher levels in gene expression-based high-risk MM patients. Moreover, high Cdc20 expression correlated with poor prognosis. Treatment of human myeloma cell lines with proTAME, an APC/C inhibitor, resulted in an accumulation of APC/CCdc20 substrate cyclin B1 and an accumulation of cells in metaphase. Moreover we observed a significant dose-dependent decrease in viability and increase in apoptosis in MM cells upon proTAME treatment. The induction of apoptosis was accompanied with caspase 3, 8, 9 and PARP cleavage. A similar metaphase arrest and induction of apoptosis were obtained with specific knockdown of Cdc20. In addition, we demonstrated the accumulation of Bim was partially responsible for the observed cell death. Combining proTAME with another APC/C inhibitor apcin or the alkylating agent melphalan resulted in enhanced anti-MM activity. This study suggests that the APC/C and its co-activator Cdc20 could be a new and promising target especially in high-risk MM patients.

Phagocyte function decreases after high-dose treatment with melphalan and autologous stem cell transplantation in patients with multiple myeloma.
    Experimental hematology, 2016, Volume: 44, Issue:5

    High-dose melphalan with autologous hematopoietic stem cell transplantation (ASCT) is the standard of care for younger patients with newly diagnosed multiple myeloma and is aimed at achieving as deep and complete a response as possible after various combinations of induction therapy. However, it is frequently associated with infectious complications. This study investigated the effects of high-dose treatment with autologous stem cell support on patients' innate immunity, with a focus on subpopulations and functioning of recently released polymorphonuclear leukocytes (PMNs) and monocytes in peripheral blood. Flow cytometry-based analysis was used to measure the degree of PMN maturation and activation, before and after ASCT and compared with healthy controls. After high-dose treatment and ASCT, a smaller proportion of patients' PMNs had the capacity for oxidative burst. Moreover, patients' PMNs, both before and after ASCT, had a reduced capacity for phagocytosis. Eosinophils, which recently have been suggested to play a role in promoting malignant plasma cell proliferation, were markedly reduced after ASCT, with slow regeneration. HLA-DR expression by monocytes was significantly depressed after ASCT, a characteristic often attributed to monocytic myeloid-derived suppressor cells. Our results suggest that several aspects of phagocytic function are impaired for at least 20 days after ASCT.

The outcomes of newly diagnosed elderly multiple myeloma patients treated at a single U.S. institution.
    Cancer medicine, 2016, Volume: 5, Issue:3

    Improvements in the outcomes of elderly multiple myeloma (MM) patients have lagged behind those of transplant-eligible patients, likely due in part to the use of less efficacious melphalan-containing regimens. To date, there are very limited data for the outcomes of elderly MM patients in the United States (US), particularly for novel agent-containing triplet regimens. In this retrospective study at a single U.S. institution, the outcomes of 117 consecutive newly diagnosed, symptomatic MM patients over the age of 70 were evaluated. The median age was 75 years (range 70-95) with significant baseline comorbidities including 36% cardiac and 20% renal (CrCl < 30 mL/min). The median follow-up was 43 months and the median number of lines of therapy during the study period was 2 (1-7). Eighty-six patients (83%) received non-melphalan doublet, triplet, or quadruplet initial therapy, most with significant planned dose attenuations. For those treated with dose-attenuated RVD (n = 34), the outcomes were particularly impressive with overall response rate (ORR), complete remission and very good partial remission (CR + VGPR), and progression-free survival (PFS) of 94%, 65%, and 36 months, respectively, and overall survival (OS) not reached. The PFS with RVD was significantly greater than that of all other regimens (P = 0.030), including RD.

High melphalan exposure is associated with improved overall survival in myeloma patients receiving high dose melphalan and autologous transplantation.
    British journal of clinical pharmacology, 2016, Volume: 82, Issue:1

    High dose melphalan (HDM) and autologous stem cell transplantation (ASCT) retains a central role in the treatment of myeloma. The aim of this study was to determine whether HDM exposure (area under the concentration vs. time curve, AUC), is significantly associated with transplant outcomes.. Melphalan concentrations were measured in six to 11 plasma samples collected after HDM (median 192 mg m(-) (2) ) to determine melphalan AUC for a total of 114 patients. Binary logistic regression was used to assess whether melphalan AUC was associated with severe (≥ grade 3) oral mucositis. Multivariate Cox regression was used to assess whether melphalan AUC was significantly associated with time to progression, progression-free survival and overall survival (OS).. Melphalan AUC ranged from 4.9 to 24.6 mg l(-1)  h, median 12.84 mg l(-1) h. Melphalan AUC above the median was a risk factor for severe mucositis (HR 1.21, 95% CI 1.06, 1.38, P = 0.004) but was also associated with significantly improved overall survival (OS) (HR 0.40, 95% CI 0.20, 0.81, P = 0.001), with an estimated median survival of 8.50 years vs. 5.38 years for high vs. low AUC groups. Multivariate analysis did not identify melphalan AUC as being significantly associated with time to progression or progression-free survival.. This large scale pharmacodynamic analysis of HDM demonstrates that high melphalan exposure is associated with improved survival, with an acceptable increase in transplant toxicity. These results suggest studies targeting a higher AUC are warranted in patients undergoing HDM and ASCT for myeloma.

Mangiferin enhances the sensitivity of human multiple myeloma cells to anticancer drugs through suppression of the nuclear factor κB pathway.
    International journal of oncology, 2016, Volume: 48, Issue:6

    Multiple myeloma (MM) is still an incurable hematological malignancy with a 5-year survival rate of ~35%, despite the use of various treatment options. The nuclear factor κB (NF-κB) pathway plays a crucial role in the pathogenesis of MM. Thus, inhibition of the NF-κB pathway is a potential target for the treatment of MM. In a previous study, we showed that mangiferin suppressed the nuclear translocation of NF-κB. However, the treatment of MM involves a combination of two or three drugs. In this study, we examined the effect of the combination of mangiferin and conventional anticancer drugs in an MM cell line. We showed that the combination of mangiferin and an anticancer drug decreased the viability of MM cell lines in comparison with each drug used separately. The decrease in the combination of mangiferin and an anticancer drug induced cell viability was attributed to increase the expression of p53 and Noxa and decreases the expression of XIAP, survivin, and Bcl-xL proteins via inhibition of NF-κB pathway. In addition, the combination treatment caused the induction of apoptosis, activation of caspase-3 and the accumulation of the cells in the sub-G1 phase of the cell cycle. Our findings suggest that the combination of mangiferin and an anticancer drug could be used as a new regime for the treatment of MM.

In vitro and in vivo activity of melflufen (J1)in lymphoma.
    BMC cancer, 2016, Apr-04, Volume: 16

    Melphalan has been used in the treatment of various hematologic malignancies for almost 60 years. Today it is part of standard therapy for multiple myeloma and also as part of myeloablative regimens in association with autologous allogenic stem cell transplantation. Melflufen (melphalan flufenamide ethyl ester, previously called J1) is an optimized derivative of melphalan providing targeted delivery of active metabolites to cells expressing aminopeptidases. The activity of melflufen has compared favorably with that of melphalan in a series of in vitro and in vivo experiments performed preferentially on different solid tumor models and multiple myeloma. Melflufen is currently being evaluated in a clinical phase I/II trial in relapsed or relapsed and refractory multiple myeloma.. Cytotoxicity of melflufen was assayed in lymphoma cell lines and in primary tumor cells with the Fluorometric Microculture Cytotoxicity Assay and cell cycle analyses was performed in two of the cell lines. Melflufen was also investigated in a xenograft model with subcutaneous lymphoma cells inoculated in mice.. Melflufen showed activity with cytotoxic IC50-values in the submicromolar range (0.011-0.92 μM) in the cell lines, corresponding to a mean of 49-fold superiority (p < 0.001) in potency vs. melphalan. In the primary cultures melflufen yielded slightly lower IC50-values (2.7 nM to 0.55 μM) and an increased ratio vs. melphalan (range 13-455, average 108, p < 0.001). Treated cell lines exhibited a clear accumulation in the G2/M-phase of the cell cycle. Melflufen also showed significant activity and no, or minimal side effects in the xenografted animals.. This study confirms previous reports of a targeting related potency superiority of melflufen compared to that of melphalan. Melflufen was active in cell lines and primary cultures of lymphoma cells, as well as in a xenograft model in mice and appears to be a candidate for further evaluation in the treatment of this group of malignant diseases.

A novel alkylating agent Melflufen induces irreversible DNA damage and cytotoxicity in multiple myeloma cells.
    British journal of haematology, 2016, Volume: 174, Issue:3

    Our prior study utilized both in vitro and in vivo multiple myeloma (MM) xenograft models to show that a novel alkylator melphalan-flufenamide (Melflufen) is a more potent anti-MM agent than melphalan and overcomes conventional drug resistance. Here we examined whether this potent anti-MM activity of melflufen versus melphalan is due to their differential effect on DNA damage and repair signalling pathways via γ-H2AX/ATR/CHK1/Ku80. Melflufen-induced apoptosis was associated with dose- and time-dependent rapid phosphorylation of γ-H2AX. Melflufen induces γ-H2AX, ATR, and CHK1 as early as after 2 h exposure in both melphalan-sensitive and -resistant cells. However, melphalan induces γ-H2AX in melphalan-sensitive cells at 6 h and 24 h; no γ-H2AX induction was observed in melphalan-resistant cells even after 24 h exposure. Similar kinetics was observed for ATR and CHK1 in meflufen- versus melphalan-treated cells. DNA repair is linked to melphalan-resistance; and importantly, we found that melphalan, but not melflufen, upregulates Ku80 that repairs DNA double-strand breaks. Washout experiments showed that a brief (2 h) exposure of MM cells to melflufen is sufficient to initiate an irreversible DNA damage and cytotoxicity. Our data therefore suggest that melflufen triggers a rapid, robust, and an irreversible DNA damage which may account for its ability to overcome melphalan-resistance in MM cells.

[Clinical Analysis of Multiple Myeloma Patients Aged over 80 Years].
    Zhongguo shi yan xue ye xue za zhi, 2016, Volume: 24, Issue:2

    To explore the clinical features, treatment response and prognosis of multiple myeloma patients aged over 80 years.. The clinical data of 23 cases of newly diagnosed multiple myeloma aged over 80 years from February 2007 to July 2014 in our hospital were analyzed retrospectively. The median age was 82, and all the patients had at least 2 complicated diseases. Only 1 patient gave up the chemotherapy because of the poor performance status, the other 22 cases received individualized treatments. Out of 23 patients, 10 received velcade containing regimen (velcade group) chemotherapy, 10 patients received melphalan containing regimen (conventional chemotherapy group) and 2 patients received lenalidomide.. 1 patient achieved complete remission, 1 patient achieved very good partial remission, 15 patients achieved partial remission, 1 patient achieved minor remission and 4 patients had progressed. Their median survival time was 19.5 months. Their survival rate of one-year, two-years, three-years were 73.9%, 39.1%, 26.1%, respectively. The median OS time and PFS time were 21.5 (9-46) vs 13 (3-23) months (P = 0.405) and 16 (5-38) vs 10 (3-19) months in the velcade group and conventional chemotherapy group, respectively. 9 cases had been alive until December 2015, while 14 cases had died.. Multiple meloma patients aged over 80 years diagnosed at advanced stage often accompanied with previous underlined diseases. Treatment should be individualized based on the evaluation of patient status. The OS and PFS time of patients could be prolonged using the velcade containing chemotherapy.

Effect of melphalan 140 mg/m(2) vs 200 mg/m(2) on toxicities and outcomes in multiple myeloma patients undergoing single autologous stem cell transplantation-a single center experience.
    Clinical transplantation, 2016, Volume: 30, Issue:8

    Although melphalan at a dose of 140 mg/m(2) (MEL140) is an acceptable conditioning regimen for autologous stem cell transplantation (ASCT) in multiple myeloma (MM) patients, very few studies compared it to the most commonly used dose of 200 mg/m(2) (MEL200). A retrospective review of records of MM patients (2001-2010) identified 33 patients who received MEL140 and 96 patients who received MEL200. As expected, significantly higher percentage of patients in the MEL140 arm were >65 years or had cardiac ejection fraction <50%, had Karnofsky score <80, or had creatinine >2 at the time of ASCT (P≤.01). There were no significant differences in incidence of treatment related mortality and morbidity. At a median follow-up of 74 months from ASCT, there were no significant differences in relapse free survival (RFS) and overall survival (OS) between the two groups. Similar proportion had myeloma status improve to ≥VGPR at 3 months post-ASCT. Usage of post-ASCT maintenance was similar. In multivariate cox proportional hazards model, only disease status of ≥VGPR at the time of ASCT significantly improved RFS (P=.024), but not OS (P=.104). In conclusion, MM patients who received MEL140 had similar long-term outcomes to MEL200 patients despite their older age and co-morbidities.

[Efficacy Comparison of Low dose Thalidomide Combined with Modified VCMP and VAD regimens for Treatment of Aged MM Patients].
    Zhongguo shi yan xue ye xue za zhi, 2016, Volume: 24, Issue:3

    To evaluate the efficacy and adverse effects of low dose thalidomide (TD) combined with modified VCMP (vincristine+cyclophosphamide+melphalan+prednisone) (TD+mVCMP) and VAD (vincristine+doxorubicin+dexamethsone) (TD+VAD) regimens for treating aged patients with MM.. A total of 47 patients with newly diagnosed MM were enrolled in this study. Among them 27 cases were treated with TD+mVCMP regimen (TD+mVCMP group), 20 cases were treated with TD+VAD regimen (TD+VAD group). The dose of TD in 2 groups all was 100 mg/d. Each patient received 4 or more courses of treatment.. Out of 27 cases in TD+mVCMP group, 9 cases achieved complete remission (CR), 5 cases-very good partial remission (VGPR), 6 cases-partial remission (PR); among 20 cases in TD+VAD group, 3 cases achieved CR, 3 cases achieved VGPR, 4 cases achieved PR. The total effective rate in 2 group was 74.1% and 50% respectively, there was statistical difference between 2 groups (P<0.05). The differences of Hb level, plasmocytic ratio of bone marrow and M protein level in 2 groups before and after treatment were significant (P<0.05). The 5 years survival rate of patients in TD+mVCMP and TD+VAD group was 72.8% and 66.9% respectively, there was no statistical difference (P>0.05). The incidence of adverse reactions including caxdiac toxicity, severe leucopenia and thrombocytopenia in TD+mVCMP group was lower than that in TD+VAD group.. Low dose TD combined with modified VCMP regimen for treatment of newly diagnosed aged patients with MM is safe and effective, which may be used as the first line treatment regimen for population in aged MM patients.

Thalidomide-based induction regimens are as effective as bortezomib-based regimens in elderly patients with multiple myeloma with cereblon expression.
    Annals of hematology, 2016, Volume: 95, Issue:10

    Cereblon (CRBN) has been identified as a primary target of immunomodulatory drugs and is considered a biomarker for the prediction of outcomes after thalidomide- or lenalidomide-based treatments. In this study, we evaluated CRBN expression in bone marrow (BM) tissue at diagnosis and investigated the relationship between CRBN expression and treatment outcomes after thalidomide- or bortezomib-based front-line therapies in 89 elderly patients with multiple myeloma (MM). CRBN expression at the time of diagnosis was evaluated with immunohistochemical (IHC) staining for myeloma cells in paraffin wax-embedded BM tissue. CRBN-immunostained slides were scored by intensity and diffuseness, and a total score of >6 was defined as CRBN-positive (CRBN(+)). Thirty-eight patients (45.2 %) were CRBN(+). Among patients treated with thalidomide-based regimens, CRBN(+) patients showed a better treatment response than did CRBN-negative patients (35.0 vs. 11.8 % complete response rate, respectively; HR = 4.038, P = 0.137). During a median follow-up of 31.8 months, patients treated with bortezomib-based regimens had a longer time to progression (TTP) than did patients treated with thalidomide-based regimens (15.6 vs. 13.2 months, respectively; P = 0.047), but early mortality occurred frequently in patients treated with bortezomib-based regimens. Additionally, there was no significant difference in survival outcomes between thalidomide- and bortezomib-based regimens in CRBN(+) patients (median TTP, 13.8 vs. 15.6 months, respectively; P = 0.842 and median OS, 39.3 vs. 30.1 months, respectively; P = 0.074). These data suggest that thalidomide-based regimens are as effective as bortezomib-based regimens in elderly patients with MM who are CRBN(+). Thus, CRBN positivity, by IHC staining, may be useful in deciding appropriate treatment options in elderly patients with MM.

Role of Myeloma-Derived MIF in Myeloma Cell Adhesion to Bone Marrow and Chemotherapy Response.
    Journal of the National Cancer Institute, 2016, Volume: 108, Issue:11

    Multiple myeloma (MM) remains an incurable cancer characterized by accumulation of malignant plasma cells in the bone marrow (BM). The mechanism underlying MM homing to BM is poorly elucidated.. The clinical significance of migration inhibitory factor (MIF) expression was examined by analyzing six independent gene expression profile databases of primary MM cells using the Student's t test and Kaplan-Meier test. Enzyme-linked immunosorbent assay was used to examine MIF expression. In vivo bioluminescent imaging was used to determine MM cell localization and treatment efficacy in human MM xenograft mouse models, with three to four mice per group. MM cell attachment to BM stromal cells (BMSCs) was monitored by cell adhesion assay. MIF regulation of the expression of adhesion molecules was determined by chromatin immunoprecipitation (ChIP) assay. Statistical tests were two-sided.. High levels of MIF were detected in MM BM (MIF level in BM plasma: healthy = 10.72 ± 5.788 ng/mL, n = 5; MM = 1811 ± 248.7 ng/mL, n = 10; P < .001) and associated with poor survival of patients (Kaplan-Meier test for MM OS: 87 MIF(high) patients, 86 MIF(low) patients, P = .02). Knocking down MIF impaired MM cell adhesion to BMSCs in vitro and led to formation of extramedullary tumors in SCID mice. MIF acted through surface receptor CXCR4 and adaptor COPS5 to regulate the expression of adhesion molecules ALCAM, ITGAV, and ITGB5 on MM cells. More importantly, MIF-deficient MM cells were sensitive to chemotherapy in vitro when cocultured with BMSCs and in vivo. MIF inhibitor 4-IPP sensitized MM cells to chemotherapy.. MIF is an important player and a novel therapeutic target in MM. Inhibiting MIF activity will sensitize MM cells to chemotherapy.

DNA repair of myeloma plasma cells correlates with clinical outcome: the effect of the nonhomologous end-joining inhibitor SCR7.
    Blood, 2016, 09-01, Volume: 128, Issue:9

    DNA repair activity of malignant cells seems to influence therapeutic outcome and patients' survival. Herein, we investigated the mechanistic basis for the link between DNA repair efficiency and response to antimyeloma therapy. Nucleotide excision repair (NER), interstrand cross-links repair (ICL/R), double-strand breaks repair (DSB/R), and chromatin structure were evaluated in multiple myeloma (MM) cell lines (melphalan-sensitive RPMI8226; melphalan-resistant LR5) and bone marrow plasma cells (BMPCs) from MM patients who responded (n = 17) or did not respond (n = 9) to subsequent melphalan therapy. The effect of DSB/R inhibition was also evaluated. Responders' BMPCs showed slower rates of NER and DSB/R (P <0022), similar rates of ICL/R, and more condensed chromatin structure compared with nonresponders. Moreover, apoptosis rates of BMPCs were inversely correlated with individual DNA repair efficiency and were higher in responders' cells compared with those of nonresponders (P = .0011). Similarly, RPMI8226 cells showed slower rates of NER and DSB/R, comparable rates of ICL/R, more condensed chromatin structure, and higher sensitivity than LR5 cells. Interestingly, cotreatment of BMPCs or cell lines with DSB/R inhibitors significantly reduced the rates of DSB/R and increased melphalan sensitivity of the cells, with the nonhomologous end-joining inhibitor SCR7 showing the strongest effect. Together, responders' BMPCs are characterized by lower efficiencies of NER and DSB/R mechanisms, resulting in higher accumulation of the extremely cytotoxic ICLs and DSBs lesions, which in turn triggers the induction of the apoptotic pathway. Moreover, the enhancement of melphalan cytotoxicity by DSB/R inhibition offers a promising strategy toward improvement of existing antimyeloma regimens.

Mortality outcomes after busulfan-containing conditioning treatment and haemopoietic cell transplantation in patients with Gilbert's syndrome: a retrospective cohort study.
    The Lancet. Haematology, 2016, Volume: 3, Issue:11

    Gilbert's syndrome is a common inherited disorder of bilirubin metabolism, characterised by mild, unconjugated hyperbilirubinaemia. However, the effect of Gilbert's syndrome on the disposition of some drugs can lead to unexpected toxicity. We tested the hypothesis that patients undergoing myeloablative conditioning and haemopoietic cell transplantation would have different mortality outcomes depending on whether or not they had laboratory evidence of Gilbert's syndrome.. In this retrospective cohort study, we used clinical and laboratory data of patients who had haemopoietic cell transplantation from Jan 1, 1991, to Dec 31, 2011. Patients were included if they had received high-dose conditioning regimens of cyclophosphamide plus total body irradiation (CY/TBI), busulfan plus cyclophosphamide (BU/CY), busulfan plus melphalan plus thioTEPA (BUMELTT), or melphalan before transplant. Patients were excluded if their original consent forms to report transplant outcomes were not signed, if consent was withdrawn, or if they were a prisoner. Patients with Gilbert's syndrome were defined as having laboratory values before the start of conditioning therapy for unconjugated serum bilirubin concentrations of at least 17·1 μmol/L (≥1 mg/dL), normal conjugated serum bilirubin, and no evidence of hepatitis, cholestasis, or haemolysis. We assessed the association of Gilbert's syndrome with overall mortality and non-relapse mortality using adjusted Cox regression models at day 200 after transplantation.. Our study cohort was 3379 patients-1855 (55%) allograft and 1524 (45%) autograft recipients. 211 (6%) patients had Gilbert's syndrome and 3168 (94%) did not have this condition. Most patients were adults (median age 45·8 years [IQR 33·2-55·5]) with haematological malignancies. For overall mortality 664 (20%) patients had died by day 200 after transplant (47 [22%] of 211 who had Gilbert's syndrome vs 617 [19%] of 3168 who did not have Gilbert's syndrome), and for non-relapse mortality 499 (92%) patients had died before relapse was recorded (38 [18%] who had Gilbert's syndrome vs 461 [15%] who did not have Gilbert's syndrome). The effect of Gilbert's syndrome on the risk of overall mortality and non-relapse mortality by transplant day 200 varied between the conditioning regimens and donor groups. In patients conditioned with a myeloablative regimen that contained busulfan (n=1131), those with Gilbert's syndrome (n=60) were at a significantly increased risk of death and non-relapse mortality by day 200 compared with those without Gilbert's syndrome (n=1071; hazard ratio [HR] 2·30, 95% CI 1·47-3·61, p=0·00030; and 2·77, 1·71-4·49, p<0·0001). In patients who received CY/TBI or melphalan conditioning regimens, those with Gilbert's syndrome had similar outcomes to those without Gilbert's syndrome (overall mortality at day 200 HR 0·90, 95% CI 0·60-1·34, p=0·60; non-relapse mortality at day 200: 0·90, 0·56-1·45, p=0·65). Analyses of causes of death and busulfan disposition provided no mechanistic explanation for the differences in mortality.. Overall mortality and non-relapse mortality at day 200 after transplant were significantly worse in patients with Gilbert's syndrome who received busulfan-containing myeloablative conditioning regimens, compared with non-Gilbert's syndrome patients. Patients with Gilbert's syndrome should receive busulfan-containing myeloablative conditioning regimens with caution.. US National Institutes of Health.

Recommend upfront consolidation with high-dose melphalan and autologous stem cell support.
    Seminars in oncology, 2016, Volume: 43, Issue:6

    The overall goal of treatment for multiple myeloma (MM) is to prolong survival for as long as possible with the minimal treatment burden for each patient. Consolidation with upfront high-dose melphalan and autologous hematopoietic stem cell transplantation (ASCT) can prolong progression-free and overall survival by deepening response. It thereby can improve quality of life by allowing patients to have a time on maintenance therapy along with infrequent office visits, making it cost-effective in many situations. The impact of minimal residual disease (MRD) negativity is important, but further studies are needed to quantify the pharmacoeconomic and quality-of-life differences between early and delayed transplant strategies. Therefore, with the currently available evidence, upfront ASCT is standard of care regardless of MRD status.

Bortezomib-based induction therapy followed by intravenous busulfan-melphalan as conditioning regimen for patients with newly diagnosed multiple myeloma.
    Leukemia & lymphoma, 2015, Volume: 56, Issue:2

    A bortezomib-containing regimen followed by high-dose therapy and autologous stem cell transplant (ASCT) is considered the standard of care for front-line therapy in younger patients with newly diagnosed multiple myeloma (MM). We analyzed the results of ASCT with an intravenous busulfan 9.6 mg/kg and melphalan 140 mg/m2 (ivBUMEL) preparative regimen in 47 patients with newly diagnosed MM who had received bortezomib-based combinations as pre-transplant induction. The overall response rate and complete response after transplant were 100% and 49%, respectively. With a median follow-up of 24.5 months, median overall survival and progression-free survival have not been reached. Mucositis and febrile neutropenia were the most frequent toxicities observed. No case of sinusoidal obstruction syndrome was observed and there was no transplant-related mortality. These results suggest that front-line induction therapy with a bortezomib-based combination followed by ASCT with ivBUMEL is an effective and well-tolerated therapeutic approach for transplant eligible patients with MM.

Copy number variations could predict the outcome of bortezomib plus melphalan and prednisone for initial treatment of multiple myeloma.
    Genes, chromosomes & cancer, 2015, Volume: 54, Issue:1

    We performed single nucleotide polymorphism (SNP) array analysis of 35 newly diagnosed symptomatic multiple myeloma (MM) patients who received bortezomib-melphalan-prednisone (VMP) to identify collaborating genetic events that could predict the outcome of treatment. A total of 340 copy number variations (CNVs) were identified, with the most frequently identified CNVs being gains on 1q, 19p, 9q, 3q, 9p, 15q, 19q, 5q, 11q, 5p, and 7q and losses on 1p, X, 13q, 14q, and 6q. The number and proportion of detected abnormalities by SNP array were associated with presence of cytogenetic abnormalities and complex karyotype. Moreover, increasing genomic complexity as ascertained by SNP arrays correlated with outcome of the VMP treatment. The frequency of CNVs was significantly different according to achievement of very good partial response (VGPR) to VMP treatment (

GWAS of 972 autologous stem cell recipients with multiple myeloma identifies 11 genetic variants associated with chemotherapy-induced oral mucositis.
    Supportive care in cancer : official journal of the Multinational Association of Supportive Care in Cancer, 2015, Volume: 23, Issue:3

    High-dose chemotherapy and autologous stem cell transplant (ASCT) to treat multiple myeloma (MM) and other cancers carries the risk of oral mucositis (OM) with sequelae including impaired nutritional and fluid intake, pain, and infectious complications. As a result of these problems, cancer treatment may have to be interrupted or delayed. In this study, we looked beyond OM's known risk factors of renal function and melphalan dose with a genome-wide association study (GWAS) to evaluate whether genetic variants in conjunction with clinical risk factors influence predisposition for OM.. Genotyping was performed using Illumina HumanOmni1-Quad v1.0 BeadChip and further assessed for data quality. We tested 892,589 germline single-nucleotide polymorphisms (SNPs) for association with OM among 972 Caucasian patients treated with high-dose melphalan and ASCT in Total Therapy clinical trials (TT2, TT3, TT4) for newly diagnosed MM. Statistical analyses included t tests, stepwise regression modeling, and logistic regression modeling to find baseline clinical factors and genotypes associated with OM.. We found that 353 (36.3 %) patients had grades 2-4 OM. Type of treatment protocol, baseline estimated glomerular filtration rate, and melphalan dose along with baseline serum albumin and female gender predicted 43.6 % of grades 2-4 OM cases. Eleven SNPs located in or near matrix metalloproteinase 13, JPH3, DHRS7C, CEP192, CPEB1/LINC00692, FBN2, ALDH1A1, and DMRTA1/FLJ35282 were associated with grades 2-4 OM. The addition of these SNPs increased sensitivity in detecting grades 2-4 OM cases to 52 %.. These SNPs may be important for their roles in inflammatory pathways, epithelial healing, and chemotherapy detoxification.

Treatment of patients with multiple myeloma over 65 yr: more tolerability or better response?
    European journal of haematology, 2015, Volume: 94, Issue:5

    Two-thirds of newly diagnosed patients with multiple myeloma (MM) are over 65 yr and/or physically unfit. Such patients are not eligible for high-dose chemotherapy or stem cell transplantation. The treatment aims in these patients should be to prolong survival by obtaining the best possible response, while maintaining good tolerability. The aim of our study was to evaluate the response to treatment and treatment-related toxicities in patients treated with conventional and novel protocols.. The records of 138 elderly (≥65 yr) patients with MM were retrospectively evaluated.. The median overall survival(OS) of the patients was 46 months. The median progression-free survival (PFS) was 18 months. The OS and PFS of the patients treated with the conventional protocols did not differ significantly from those treated with the novel protocols. The statistical analysis of the quality of the response to the treatment with the conventional and novel therapies showed that complete remission (CR), combined with a very good partial response (VGPR), was significantly higher in the latter. However, the toxicities were higher in the novel treatment group.. The novel drug protocols significantly increased the quality of the responses of elderly patients with MM to therapy, but they did not increase the patients' tolerability.

Cyclophosphamide-based hematopoietic stem cell mobilization before autologous stem cell transplantation in newly diagnosed multiple myeloma.
    Journal of clinical apheresis, 2015, Volume: 30, Issue:3

    High-dose cyclophosphamide (Cy) is frequently employed for peripheral blood mobilization of hematopoietic stem cells before high-dose chemotherapy with autologous stem cell transplantation (ASCT) in multiple myeloma (MM). The benefit of mobilization with Cy over filgrastim (granulocyte colony-stimulating factor; G-CSF) alone is unclear. Between 2000 and 2008, 167 patients with newly diagnosed MM underwent single ASCT after melphalan conditioning at our institution. Seventy-three patients were mobilized with G-CSF alone, and 94 patients with Cy plus G-CSF (Cy+G-CSF). We retrospectively analyzed Cy's impact on both toxicity and efficacy. Mobilization efficiency was augmented by Cy; a mean total of 12 versus 5.8 × 10(6) CD34+ cells/kg were collected from patients mobilized with Cy+G-CSF versus G-CSF, respectively, (P < 0.01), over a mean of 1.6 versus 2.2 days of peripheral blood apheresis (p = 0.001). Mobilization-related toxicity was also, however, augmented by Cy; 14% of Cy+G-CSF patients were hospitalized because of complications versus none receiving G-CSF (P < 0.0001). Toxicity, including death, related to ASCT was similar between cohorts. Regarding long-term outcomes, multivariate analysis revealed no difference for Cy+G-CSF versus G-CSF (hazard ratio 0.8 for event-free survival [95% confidence interval {CI} 0.57-1.25] and 0.96 for overall survival [95% CI 0.61-1.54]). In summary, we show that mobilization with Cy increases toxicity without positively impacting long-term outcomes in MM. Our findings place into question Cy's benefit as a routine component of stem cell mobilization regimens in MM. Randomized trials are needed to elucidate the risks and benefits of Cy more definitively.

PJ34, a poly(ADP-ribose) polymerase (PARP) inhibitor, reverses melphalan-resistance and inhibits repair of DNA double-strand breaks by targeting the FA/BRCA pathway in multidrug resistant multiple myeloma cell line RPMI8226/R.
    International journal of oncology, 2015, Volume: 46, Issue:1

    There is still no ideal treatment for multidrug resistant multiple myeloma, looking for drugs which can reverse chemotherapy resistance and enhance curative effects of chemotherapy drugs becomes a problem that needs to be solved urgently. Poly(ADP-ribose) polymerase inhibitors appear to be an important tool for medical therapy of several malignancies. In the present study, we investigated the potential of the PARP-1 inhibitor PJ34, in vitro, to further enhance the efficacy of the traditional chemotherapy drug melphalan in the multidrug-resistant multiple myeloma cell line RPMI8226/R. The effects of different concentrations of PJ34 and melphalan on cell proliferation were determined by the CCK-8 assay. The expressions of FA/BRCA pathway-related factors were detected by western blotting and RT-PCR. The percentage of cell apoptosis was measured with flow cytometry. DNA double-strand break (DSB) repair was quantified by γH2AX immunofluorescence. In addition, DNA damage repair at the level of the individual cell was determined by comet assay. Co-administration of PJ34 and melphalan had synergistic inhibitory effects on the proliferation of RPMI8226/R cells, suggesting more powerful antitumor activities. The apoptosis percentage also was increased more obviously by the treatment of melphalan plus PJ34. The activation of FA/BRCA pathway was inhibited by downregulation of related factors including FANCD2, BRCA2 and Rad51. PJ34 significantly increased the ratio of γH2AX-positive cells and the number of foci/cells. The comet tail rate of cells, tail length, tail moment and Olive tail moment all increased after PJ34 treatment in RPMI8226/R cells. These results indicate that PJ34 combined treatment with melphalan produces synergistic effects and reverses multidrug resistance of RPMI8226/R cells effectively. PJ34 cannot induce DNA damage directly, but it may increase the DNA damage induced by melphalan through inhibiting DNA damage repair. The suppression of FA/BRCA pathway may be the mechanism. Therefore, we suggest that PARP inhibitors may deserve future investigations as tools for medical treatment of multidrug resistant multiple myeloma.

Modulation of cell metabolic pathways and oxidative stress signaling contribute to acquired melphalan resistance in multiple myeloma cells.
    PloS one, 2015, Volume: 10, Issue:3

    Alkylating agents are widely used chemotherapeutics in the treatment of many cancers, including leukemia, lymphoma, multiple myeloma, sarcoma, lung, breast and ovarian cancer. Melphalan is the most commonly used chemotherapeutic agent against multiple myeloma. However, despite a 70-80% initial response rate, virtually all patients eventually relapse due to the emergence of drug-resistant tumour cells. By using global proteomic and transcriptomic profiling on melphalan sensitive and resistant RPMI8226 cell lines followed by functional assays, we discovered changes in cellular processes and pathways not previously associated with melphalan resistance in multiple myeloma cells, including a metabolic switch conforming to the Warburg effect (aerobic glycolysis), and an elevated oxidative stress response mediated by VEGF/IL8-signaling. In addition, up-regulated aldo-keto reductase levels of the AKR1C family involved in prostaglandin synthesis contribute to the resistant phenotype. Finally, selected metabolic and oxidative stress response enzymes were targeted by inhibitors, several of which displayed a selective cytotoxicity against the melphalan-resistant cells and should be further explored to elucidate their potential to overcome melphalan resistance.

Proof-of-Principle for Immune Control of Global HIV-1 Reactivation In Vivo.
    Clinical infectious diseases : an official publication of the Infectious Diseases Society of America, 2015, Jul-01, Volume: 61, Issue:1

    Emerging data relating to human immunodeficiency virus type 1 (HIV-1) cure suggest that vaccination to stimulate the host immune response, particularly cytotoxic cells, may be critical to clearing of reactivated HIV-1-infected cells. However, evidence for this approach in humans is lacking, and parameters required for a vaccine are unknown because opportunities to study HIV-1 reactivation are rare.. We present observations from a HIV-1 elite controller, not treated with combination antiretroviral therapy, who experienced viral reactivation following treatment for myeloma with melphalan and autologous stem cell transplantation. Mathematical modeling was performed using a standard viral dynamic model. Enzyme-linked immunospot, intracellular cytokine staining, and tetramer staining were performed on peripheral blood mononuclear cells; in vitro CD8 T-cell-mediated control of virion production by autologous CD4 T cells was quantified; and neutralizing antibody titers were measured.. Viral rebound was measured at 28,000 copies/mL on day 13 post-transplant before rapid decay to <50 copies/mL in 2 distinct phases with t1/2 of 0.71 days and 4.1 days. These kinetics were consistent with an expansion of cytotoxic effector cells and killing of productively infected CD4 T cells. Following transplantation, innate immune cells, including natural killer cells, recovered with virus rebound. However, most striking was the expansion of highly functional HIV-1-specific cytotoxic CD8 T cells, at numbers consistent with those applied in modeling, as virus control was regained.. These observations provide evidence that the human immune response is capable of controlling coordinated global HIV-1 reactivation, remarkably with potency equivalent to combination antiretroviral therapy. These data will inform design of vaccines for use in HIV-1 curative interventions.

Targeting the pro-survival protein MET with tivantinib (ARQ 197) inhibits growth of multiple myeloma cells.
    Neoplasia (New York, N.Y.), 2015, Volume: 17, Issue:3

    The hepatocyte growth factor (HGF)/MNNG HOS transforming gene (MET) pathway regulates cell growth, survival, and migration. MET is mutated or amplified in several malignancies. In myeloma, MET is not mutated, but patients have high plasma concentrations of HGF, high levels of MET expression, and gene copy number, which are associated with poor prognosis and advanced disease. Our previous studies demonstrated that MET is critical for myeloma cell survival and its knockdown induces apoptosis. In our current study, we tested tivantinib (ARQ 197), a small-molecule pharmacological MET inhibitor. At clinically achievable concentrations, tivantinib induced apoptosis by >50% in all 12 human myeloma cell lines tested. This biologic response was associated with down-regulation of MET signaling and inhibition of the mitogen-activated protein kinase and phosphoinositide 3-kinase pathways, which are downstream of the HGF/MET axis. Tivantinib was equally effective in inducing apoptosis in myeloma cell lines resistant to standard chemotherapy (melphalan, dexamethasone, bortezomib, and lenalidomide) as well as in cells that were co-cultured with a protective bone marrow microenvironment or with exogenous cytokines. Tivantinib induced apoptosis in CD138+ plasma cells from patients and demonstrated efficacy in a myeloma xenograft mouse model. On the basis of these data, we initiated a clinical trial for relapsed/refractory multiple myeloma (MM). In conclusion, MET inhibitors may be an attractive target-based strategy for the treatment of MM.

Does low-molecular-weight heparin influence the antimyeloma effects of thalidomide? A retrospective analysis of data from the GIMEMA, Nordic and Turkish myeloma study groups.
    Acta haematologica, 2015, Volume: 133, Issue:4

    Low-molecular-weight heparin (LMWH) has been shown to prolong survival among patients with solid tumors, but its role among myeloma patients is unknown.. Data from the GIMEMA (Gruppo Italiano Malattie Ematologiche dell'Adulto), Nordic and Turkish myeloma study groups comparing melphalan and prednisolone with (MPT, n: 404) or without thalidomide (MP, n: 393) are analyzed for effects of LMWH. Forty percent (159/394) of the patients on MPT and 7.4% (29/390) in the MP arm received LMWH.. Thalidomide improved response and progression-free survival (PFS). Regardless of thalidomide treatment, response rate was higher among those receiving LMWH vs. none vs. other anticoagulants (58.1 vs. 44.9 vs. 50.4%, p = 0.01). PFS was significantly longer (median 32 vs. 21 and 17 vs. 17 months, p = 0.004) only among international scoring system (ISS) I patients receiving MPT ± LMWH vs. MP ± LMWH. The group of MPT patients who also received LMWH had a better OS compared to those who did not [45 months, 95% confidence interval (CI) 27.7-62.3, vs. 32 months, 95% CI 26.1-37.9; p = 0.034]. When multivariate analysis was repeated in subgroups, thalidomide was no longer a significant factor (response, PFS) among those receiving LMWH.. Addition of LMWH to MPT, in particular in patients with low ISS, suggests additive effects, but the results are limited by the retrospective design of our study.

Risk stratification model in elderly patients with multiple myeloma: clinical role of magnetic resonance imaging combined with international staging system and cytogenetic abnormalities.
    Acta haematologica, 2015, Volume: 134, Issue:1

    The International Staging System (ISS) does not take into consideration the clinical role of imaging modalities in multiple myeloma (MM), even though these are important. Some studies have indicated a lack of impact of ISS in MM patients who receive novel agents. Therefore, accessible novel risk stratification might be needed in elderly MM patients receiving conventional therapy or novel agents. We analyzed 198 newly diagnosed and symptomatic MM patients who were not eligible for transplantation. The initial treatment regimen was therapy with melphalan-prednisone (MP, n = 44), thalidomide-cyclophosphamide-dexamethasone (n = 89) or bortezomib-MP (VMP, n = 65). The magnetic resonance imaging (MRI) pattern was normal in 34 patients, focal in 30 and diffuse/variegated in 134. High-risk cytogenetic abnormalities were not associated with the diffuse/variegated MRI pattern (p = 0.182). ISS stage III [progression-free survival (PFS) p = 0.005; overall survival (OS) p = 0.027], high-risk cytogenetic abnormalities (PFS p = 0.001; OS p < 0.001) and diffuse/variegated MRI pattern (PFS p < 0.001; OS p < 0.001) were independently associated with poorer PFS and OS. Patients were further stratified according to the 3 prognostic factors. The PFS and OS of the 3 groups differed significantly. The addition of the diffuse/variegated MRI pattern may improve the prognostic potential of the current staging system which includes ISS and cytogenetic abnormalities.

Autologous Stem Cell Transplantation Is an Effective Salvage Therapy for Primary Refractory Multiple Myeloma.
    Biology of blood and marrow transplantation : journal of the American Society for Blood and Marrow Transplantation, 2015, Volume: 21, Issue:7

    High-dose therapy and autologous stem cell transplantation (ASCT) have proven efficacy in patients with multiple myeloma responding well to induction therapy. For those who fail to achieve a stable partial response (PR), the effect of ASCT is unclear. We report on 126 patients identified from a national database, who underwent ASCT having achieved

Autologous Stem-Cell Transplantation Without Hematopoietic Support for the Treatment of Hematologic Malignancies in Jehovah's Witnesses.
    Journal of clinical oncology : official journal of the American Society of Clinical Oncology, 2015, May-20, Volume: 33, Issue:15

    Autologous stem-cell transplantation (ASCT) has shown to provide curative benefit in patients with relapsed lymphoma and multiple myeloma (MM), often requiring hematopoietic support until marrow engraftment. Because of Jehovah's Witnesses' (JW) refusal of blood products, treatment challenges arise. This study represents 125 JWs with lymphoma (n = 55), MM (n = 68), or amyloidosis (n = 2), treated with high-dose chemotherapy (HDC) and ASCT without transfusions.. Priming with intravenous iron and erythropoietin occurred to increase hemoglobin (Hb) pretransplantation. Cytokine mobilization of stem-cells was used. Delay to HDC was done to allow Hb and platelets to approach 11 g/dL and 100 × 10(3)/μL, respectively. Patients with MM received a standard dose of melphalan 200 mg/m(2), with dose reduction for severe kidney dysfunction. Patients with lymphoma received carmustine 300 mg/m(2), cyclophosphamide 1,500 mg/m(2) on days 2 through 5 (total 6 g/m(2)), and etoposide 700 mg/m(2) per day on days 2 through 4 (total 2,100 mg/m(2)). Post-transplantation, a combination of granulocyte colony-stimulating factor, erythropoietin, aminocaproic acid, and phytonadione was administered.. There were two major and 15 minor bleeding complications, none occurring at platelets less than 5.0 × 10(3)/μL, with six (4.8%) treatment-related mortalities. The median decrease in Hb was 5.0 g/dL, with median Hb nadir of 7.0 g/dL. The median number of days with platelet count less than 10 × 10(3)/μL was 3, with median platelet nadir of 5.0 × 10(3)/μL. Cardiac complications occurred in 40 patients (32%).. ASCT can safely be performed without transfusion support. A platelet transfusion trigger of ≤ 5 × 10(3)/μL may be appropriate in select patients. Pharmacotherapy and cardiac monitoring are effective in the management of cardiac complications.

Recurrent extramedullary plasmacytoma in asymptomatic multiple myeloma: a case report.
    Journal of medical case reports, 2015, Feb-19, Volume: 9

    The gross majority of extramedullary plasmacytomas arise in the lymphatic tissue of the upper respiratory tract. On average, one third of patients with a solid plasmacytoma will develop multiple myeloma, resulting in a worse clinical outcome. We describe a case of rapid recurrent extramedullary plasmacytomas in the background of an asymptomatic multiple myeloma.. A 71-year-old, white Caucasian woman presented with three extramedullary plasmacytomas occurring within a short time period. The third plasmacytoma was accompanied by progressive cervical pain and swallow dysfunction. Additional immunostaining test results were negative for CD56 and showed high MIB-1 expression in the extramedullary plasmacytoma and low MIB-1 expression in the bone marrow. A conventional swallow X-ray did not show any obstruction, however a magnetic resonance imaging scan of her cervical backbone revealed an extramedullary plasmacytoma, threatening her spinal cord. A short course of radiation therapy alleviated her pain and during almost a two-year follow-up period, the multiple myeloma remained asymptomatic, despite the rise in immunoglobulin A lambda levels. After the appearance of the third plasmacytoma, systemic chemotherapy was started to prevent the development of a fourth plasmacytoma, despite the asymptomatic character of the multiple myeloma.. In this case report we describe the rapid appearance of extramedullary plasmacytomas in the background of an asymptomatic multiple myeloma. An immunohistochemical analysis was negative for CD56 and showed high MIB-1 expression in the extramedullary plasmacytoma and low MIB-1 expression in the bone marrow, contributing to the potential underlying pathophysiology of the recurrent extramedullary plasmacytomas and their genetic changes. Systemic chemotherapy was started and no fourth extramedullary plasmacytoma has developed since.

MicroRNA-451 regulates stemness of side population cells via PI3K/Akt/mTOR signaling pathway in multiple myeloma.
    Oncotarget, 2015, Jun-20, Volume: 6, Issue:17

    Side population (SP) cells are an enriched source of cancer-initiating cells with stemness characteristics, generated by increased ABC transporter activity, which has served as a unique hallmark for multiple myeloma (MM) stem cell studies. Here we isolated and identified MM SP cells via Hoechst 33342 staining. Furthermore, we demonstrate that SP cells possess abnormal cell cycle, clonogenicity, and high drug efflux characteristics-all of which are features commonly seen in stem cells. Interestingly, we found that bortezomib, As2O3, and melphalan all affected apoptosis and clonogenicity in SP cells. We followed by characterizing the miRNA signature of MM SP cells and validated the specific miR-451 target tuberous sclerosis 1 (TSC1) gene to reveal that it activates the PI3K/Akt/mTOR signaling in MM SP cells. Inhibition of miR-451 enhanced anti-myeloma novel agents' effectiveness, through increasing cells apoptosis, decreasing clonogenicity, and reducing MDR1 mRNA expression. Moreover, the novel specific PI3K/Akt/mTOR signaling inhibitor S14161 displayed its prowess as a potential therapeutic agent by targeting MM SP cells. Our findings offer insights into the mechanisms regulating MM SP cells and provide a novel strategy to overcome resistance to existing therapies against myeloma.

A peptide nucleic acid targeting nuclear RAD51 sensitizes multiple myeloma cells to melphalan treatment.
    Cancer biology & therapy, 2015, Volume: 16, Issue:6

    RAD51-mediated recombinational repair is elevated in multiple myeloma (MM) and predicts poor prognosis. RAD51 has been targeted to selectively sensitize and/or kill tumor cells. Here, we employed a peptide nucleic acid (PNA) to inhibit RAD51 expression in MM cells. We constructed a PNA complementary to a unique segment of the RAD51 gene promoter, spanning the transcription start site, and conjugated it to a nuclear localization signal (PKKKRKV) to enhance cellular uptake and nuclear delivery without transfection reagents. This synthetic construct, (PNArad51_nls), significantly reduced RAD51 transcripts in MM cells, and markedly reduced the number and intensity of de novo and melphalan-induced nuclear RAD51 foci, while increasing the level of melphalan-induced γH2AX foci. Melphalan alone markedly induced the expression of 5 other genes involved in homologous-recombination repair, yet suppression of RAD51 by PNArad51_nls was sufficient to synergize with melphalan, producing significant synthetic lethality of MM cells in vitro. In a SCID-rab mouse model mimicking the MM bone marrow microenvironment, treatment with PNArad51_nls ± melphalan significantly suppressed tumor growth after 2 weeks, whereas melphalan plus control PNArad4µ_nls was ineffectual. This study highlights the importance of RAD51 in myeloma growth and is the first to demonstrate that anti-RAD51 PNA can potentiate conventional MM chemotherapy.

Autologous Hematopoietic Stem Cell Transplantation-10 Years of Data From a Developing Country.
    Stem cells translational medicine, 2015, Volume: 4, Issue:8

    Intensive chemotherapy followed by autologous stem cell transplantation is the treatment of choice for patients with hematological malignancies. The objective of the present study was to evaluate the outcomes of patients with mainly lymphoma and multiple myeloma after autologous stem cell transplant. The pretransplant workup consisted of the complete blood count, an evaluation of the liver, kidney, lung, and infectious profile, chest radiographs, and a dental review. For lymphoma, all patients who achieved at least a 25% reduction in the disease after salvage therapy were included in the study. Mobilization was done with cyclophosphamide, followed by granulocyte colony-stimulating factor, 300 µg twice daily. The conditioning regimens included BEAM (carmustine, etoposide, cytarabine, melphalan) and high-dose melphalan. A total of 206 transplants were performed from April 2004 to December 2014. Of these, 137 were allogeneic transplants and 69 were autologous. Of the patients receiving an autologous transplant, 49 were male and 20 were female. Of the 69 patients, 26 underwent transplantation for Hodgkin's lymphoma, 23 for non-Hodgkin's lymphoma, and 15 for multiple myeloma and 4 and 1 for Ewing's sarcoma and neuroblastoma, respectively. The median age ± SD was 34 ± 13.1 years (range, 4-64). A mean of 4.7 × 10⁸ ± 1.7 mononuclear cells per kilogram were infused. The median time to white blood cell recovery was 18.2 ± 5.34 days. Transplant-related mortality occurred in 10 patients. After a median follow-up period of 104 months, the overall survival rate was 86%. High-dose chemotherapy, followed by autologous stem cell transplant, is an effective treatment option for patients with hematological malignancies, allowing further consolidation of response.

Genotoxic Stress Induces Senescence-Associated ADAM10-Dependent Release of NKG2D MIC Ligands in Multiple Myeloma Cells.
    Journal of immunology (Baltimore, Md. : 1950), 2015, Jul-15, Volume: 195, Issue:2

    Genotoxic stress can promote antitumor NK cell responses by upregulating the surface expression of activating ligands on cancer cells. Moreover, a number of studies suggested a role for soluble NK group 2D ligands in the impairment of NK cell tumor recognition and killing. We investigated whether genotoxic stress could promote the release of NK group 2D ligands (MHC class I-related chain [MIC]A and MICB), as well as the molecular mechanisms underlying this event in human multiple myeloma (MM) cells. Our results show that genotoxic agents used in the therapy of MM (i.e., doxorubicin and melphalan) selectively affect the shedding of MIC molecules that are sensitive to proteolytic cleavage, whereas the release of the short MICA*008 allele, which is frequent in the white population, is not perturbed. In addition, we found that a disintegrin and metalloproteinase 10 expression is upregulated upon chemotherapeutic treatment both in patient-derived CD138(+)/CD38(+) plasma cells and in several MM cell lines, and we demonstrate a crucial role for this sheddase in the proteolytic cleavage of MIC by means of silencing and pharmacological inhibition. Interestingly, the drug-induced upregulation of a disintegrin and metalloproteinase 10 on MM cells is associated with a senescent phenotype and requires generation of reactive oxygen species. Moreover, the combined use of chemotherapeutic drugs and metalloproteinase inhibitors enhances NK cell-mediated recognition of MM cells, preserving MIC molecules on the cell surface and suggesting that targeting of metalloproteinases in conjunction with chemotherapy could be exploited for NK cell-based immunotherapeutic approaches, thus contributing to avoid the escape of malignant cells from stress-elicited immune responses.

Risks, severity and timing of infections in patients with multiple myeloma: a longitudinal cohort study in the era of immunomodulatory drug therapy.
    British journal of haematology, 2015, Volume: 171, Issue:1

    We defined the epidemiology and clinical predictors of infection in patients with multiple myeloma (MM) receiving immunomodulatory drugs (IMiDs), proteasome inhibitors (PI) and autologous haematopoietic stem cell transplant (ASCT) in a large longitudinal cohort study. Clinical and microbiology records of patients with MM diagnosed between January 2008 and December 2012 were reviewed to capture patient demographics, characteristics of myeloma and infections (type, severity, outcomes). Conditional risk set modelling was used to determine clinical predictors of infection. One hundred and ninety-nine patients with MM with 771 episodes of infection were identified. 44·6% of infections were clinically defined, 35·5% were microbiologically defined and 19·9% were fever of unknown focus. There was a bimodal peak in incidence of bacterial (4-6 and 70-72 months) and viral infections (7-9 and 52-54 months) following disease diagnosis. Chemotherapy regimens high-dose melphalan [hazard ratio (HR) = 2·07], intravenous cyclophosphamide (HR = 1·96) and intensive combination systemic chemotherapy (HR = 1·86) and cumulative doses of corticosteroid (HR = 3·06 at highest dose) were independently associated with increased risk of infection overall (P < 0·05). IMiDs and PI and other clinical factors were not independently associated with increased risk of infection. New approaches to prevention and treatment of infection should focus upon identified periods of risk and treatment-related risk factors.

Outpatient Autologous Stem Cell Transplantation for Patients With Myeloma.
    Clinical lymphoma, myeloma & leukemia, 2015, Volume: 15, Issue:9

    High-dose melphalan with autologous stem cell support improves survival for patients with myeloma. For selected patients, we have been using a protocol of short hospitalization, discharging patients to home with careful outpatient monitoring in the office, which we hypothesized would reduce complications and utilization of inpatient beds.. We reviewed 301 initial autologous transplants for myeloma, categorized as brief stay (≤ 4 days, 82 patients) or prolonged stay (≥ 5 days, 219 patients). Selection for a brief stay was determined by clinical characteristics, availability of caregivers at home, distance from our medical center, and patient preference.. Within the brief stay population, 67% required readmission before day + 100, but this group still had fewer cumulative hospital days (9 vs. 18, P < .0001). There were fewer documented infections among brief stay patients (22% vs. 46% P < .001) and fewer admissions to intensive care units (0% vs. 5.9%, P = .02). The groups had similar rates of bleeding (1.2% vs. 1.4% P = 1.0) and thrombosis (3.7% vs. 4.6% P = 1.0). No patients in the brief stay group died within 100 days, compared with mortality of 1.8% (P = .6) in the prolonged stay group.. Carefully selected patients receiving an autologous stem cell transplant for treatment of myeloma can be managed with a brief initial hospitalization and outpatient follow-up, with low morbidity and mortality.

Impact of Prophylactic Levofloxacin on Rates of Bloodstream Infection and Fever in Neutropenic Patients with Multiple Myeloma Undergoing Autologous Hematopoietic Stem Cell Transplantation.
    Biology of blood and marrow transplantation : journal of the American Society for Blood and Marrow Transplantation, 2015, Volume: 21, Issue:10

    Few studies have evaluated the role of antibacterial prophylaxis during neutropenia in patients with multiple myeloma undergoing autologous hematopoietic stem cell transplantation (HSCT). At our center, levofloxacin prophylaxis was initiated in June 2006 in patients with myeloma who were undergoing autologous HSCT. We compared the incidence of bloodstream infection (BSI) and fever and neutropenia (FN) within 30 days of transplantation before (January 2003 to May 2006) and after (June 2006 to April 2010) the initiation of levofloxacin prophylaxis in patients undergoing autologous HSCT for myeloma. We also compared rates of BSI and FN during the same time periods in autologous HSCT recipients with lymphoma who did not receive antibacterial prophylaxis during either time period. After the initiation of levofloxacin prophylaxis, the BSI rate decreased from 41.2% (49 of 119) to 14.7% (23 of 156) and the rate of FN decreased from 91.6% to 60.9% in patients with myeloma (P < .001, for each). In contrast, rates of BSI (43.1% versus 47.3%; P = .50) and FN (98.8% versus 97.1%; P = .63) did not change in patients with lymphoma. Levofloxacin prophylaxis was independently associated with decreased odds of BSI (odds ratio, .27; 95% confidence interval, .14 to .51; P < .001) and FN (odds ratio, .18; 95% confidence interval, .09 to .36; P < .001) in multivariate analysis. Patients with myeloma had a nonsignificant increase in the risk of BSI due to levofloxacin-resistant Enterobacteriaceae (5% versus 1%, P = .08) and Clostridium difficile infection (7% versus 3%, P = .12) after the initiation of levofloxacin prophylaxis but did not have higher rates of BSI due to other resistant bacteria. Levofloxacin prophylaxis is associated with decreased risk of BSI and FN in patients with myeloma undergoing autologous HSCT.

BEAM Conditioning Regimen Has Higher Toxicity Compared With High-Dose Melphalan for Salvage Autologous Hematopoietic Stem Cell Transplantation in Multiple Myeloma.
    Clinical lymphoma, myeloma & leukemia, 2015, Volume: 15, Issue:9

    Salvage autologous stem cell transplantation (ASCT) is increasingly used for eligible patients with multiple myeloma (MM) for progress after conventional chemotherapy. We recently used BEAM (BCNU, etoposide, cytarabine, and melphalan) conditioning for patients with myeloma receiving salvage ASCT whose disease progressed after a first ASCT with high-dose melphalan (HDM). We report safety and efficacy of BEAM salvage ASCT in MM in comparison with HDM-based salvage ASCT.. Between 2008 and 2013, 43 consecutive patients received salvage ASCT for MM (19 with HDM; 24 with BEAM).. The BEAM group had a higher incidence of infections, intensive level of care, and fever (19 vs. 13 patients; P = .02), whereas the melphalan group had a higher incidence of mucositis (7 vs. 2 patients; P = .03). Other toxicities were not different. There was no significant difference in disease status and response rate before and after salvage ASCT between the 2 groups. The median time of follow-up after salvage ASCT was 5 and 9 months and the median progression-free survival (PFS) times were 7.7 and 12.1 months (P = .82) for BEAM and melphalan, respectively.. BEAM seemed to be associated with higher toxicity with comparable efficacy to HDM ASCT. Longer follow-up is needed to determine whether there is any significant difference in PFS between the 2 groups.

The novel biomarker of alternative macrophage activation, soluble mannose receptor (sMR/sCD206): Implications in multiple myeloma.
    Leukemia research, 2015, Volume: 39, Issue:9

    Tumor-associated macrophages (TAMs) play an important role in the pathophysiology of human malignancies. They support growth of cancer cells by promoting angiogenesis, and by inhibiting tumour cell apoptosis and anti-tumor immune reactions. Several membrane proteins are well-described markers of human TAMs, including the haemoglobin scavenger receptor CD163 and the macrophage mannose receptor (MR/CD206). Interestingly, both CD163 and MR exist as soluble serum proteins (sCD163 and sMR) that may reflect the activation state of tissue macrophages, including TAMs. Here, we report the first data on sMR as a biomarker in patients with a malignant disease. We have measured concentrations of sMR in peripheral blood serum (n=104) from patients with newly diagnosed multiple myeloma (MM) by an enzyme-linked immunosorbent assay, and examined associations with data from medical records. At diagnosis, sMR levels were elevated in 27% of patients, and decreased after treatment. Further, sMR levels were associated with prognostic markers in MM, and elevated sMR (>0.43mg/L) was an independent marker of overall survival in a multivariate analysis (HR=2.20, P=0.006). Levels of sMR in blood samples showed significant association with sCD163, which may indicate common origin from CD163+MR+TAMs.

High-dose therapy improves the bone remodelling compartment canopy coverage and bone formation in multiple myeloma.
    British journal of haematology, 2015, Volume: 171, Issue:3

    Bone loss in multiple myeloma (MM) is caused by an uncoupling of bone formation to resorption trigged by malignant plasma cells. Increasing evidence indicates that the bone remodelling compartment (BRC) canopy, which normally covers the remodelling sites, is important for coupled bone remodelling. Loss of this canopy has been associated with bone loss. This study addresses whether the bone remodelling in MM is improved by high-dose therapy. Bone marrow biopsies obtained from 20 MM patients, before and after first-line treatment with high-dose melphalan followed by autologous stem cell transplantation, and from 20 control patients with monoclonal gammopathy of undetermined significance were histomorphometrically investigated. This investigation confirmed that MM patients exhibited uncoupled bone formation to resorption and reduced canopy coverage. More importantly, this study revealed that a good response to anti-myeloma treatment increased the extent of formative bone surfaces with canopy, and reduced the extent of eroded surfaces without canopy, reverting the uncoupled bone remodelling, while improving canopy coverage. The association between improved coupling and the canopy coverage supports the notion that canopies are critical for the coupling of bone formation to resorption. Furthermore, this study supports the observation that systemic bone disease in MM can be reversed in MM patients responding to anti-myeloma treatment.

Outcomes of primary refractory multiple myeloma and the impact of novel therapies.
    American journal of hematology, 2015, Volume: 90, Issue:11

    Over the past decade, use of novel agents, including immunomodulatory drugs (IMiDs) and proteasome inhibitors (PIs) has resulted in high response rates and improvement in overall survival (OS) for patients with multiple myeloma (MM); however, the prognostic significance of refractoriness to these agents when used as initial therapy has not been extensively studied. We reviewed the outcomes of 816 consecutive patients treated for MM at our institution since 2006 to evaluate the survival difference between those achieving at least a partial response (PR) to induction therapy and those who were primary refractory. The median OS from start of therapy was significantly shorter for the primary refractory group at 3.6 vs. 7.6 years for the responding patients (P < 0.001). The difference in median OS persisted when only patients receiving a novel agent as part of induction therapy were considered (3.6 vs. 7.9 years, P < 0.001) and in a 4-month landmark analysis (4.2 vs. 7.6 years, P < 0.001). The median OS for patients achieving a complete response (CR), very good partial response (VGPR), PR, or less than PR was not reached (NR), 6.1, 6.4, and 4.2 years from the 4-month landmark, respectively (P < 0.001). The comparatively poor outcomes of patients refractory to induction therapy in the current era of novel agents suggests that this high-risk subpopulation must be further studied for predictors of resistance and, when identified, should be targeted for clinical trials.

Target therapy of multiple myeloma by PTX-NPs and ABCG2 antibody in a mouse xenograft model.
    Oncotarget, 2015, Sep-29, Volume: 6, Issue:29

    Multiple myeloma (MM) remains to be an incurable disease. The purpose of this study was to evaluate the effect of ABCG2 monoclonal antibody (McAb) combined with paclitaxel (PTX) conjugated with Fe3O4 nanoparticles (NPs) on MM progressed from cancer stem cells (CSCs) in non-obese-diabetic/severe-combined-immunodeficiency (NOD/SCID) mouse model. Mice were injected with MM CSCs as marked by CD138-CD34- phenotypes through tail veins. The developed MM mice were examined by micro-computer tomography scanning, ultrasonography and enzyme-linked immunosorbent analysis. These mice were then intravenously treated with different combinations of NPs, PTX, McAb, PTX-NPs and melphalan/prednisone once a week for four weeks. The injected mice developed characteristic MM-associated syndromes, including lytic bone lesions, renal damages and proteinuria. All the treated mice showed decrease in bone lesions, renal damages and anemia but increase in apoptosis compared with the mice treated with NPs only. In particular, the treatment with ABCG2 McAb plus PTX-NPs induced the strongest therapeutic response and had an efficacy even better than that of melphalan/prednisone, a conventional regimen for MM patients. These data suggest that PTX-NPs with ABCG2 McAb can be developed into potential treatment regimens for patients with relapsed/refractory MM.

A case of melphalan sustained accumulation in an 80-year old patient.
    International journal of clinical pharmacy, 2015, Volume: 37, Issue:6

    Case We report the case of melphalan accumulation in an 80-year old female with multiple myeloma. Her initial health status was good except for a moderate chronic renal failure (estimated glomerular filtration rate: 31 ml/min) and anemia. Among other drugs, her usual treatment included trimethoprim/sulfamethoxazole and the patient received melphalan from day 1 to day 4 for multiple myeloma. On day 13, she was admitted in intensive care unit for acute renal failure and severe sepsis with pancytopenia. Usual treatments were stopped. Melphalan blood concentrations were 123.6 ng/ml on day 16 and 87.5 ng/ml on day 17 while cerebrospinal fluid concentration was 173.8 ng/ml on day 25. Patient recovered on day 30. Melphalan accumulation may be explained by substrate competition between sulfamethoxazole and melphalan in metabolism pathway and chronic renal failure. Conclusion close clinical and renal monitoring should be performed in patient receiving melphalan and sulfamethoxazole.

Downregulation of MicroRNA-152 contributes to high expression of DKK1 in multiple myeloma.
    RNA biology, 2015, Volume: 12, Issue:12

    Multiple myeloma (MM) induced bone lesion is one of the most crippling characteristics, and the MM secreted Dickkopf-1 (DKK1) has been reported to play important role in this pathologic process. However, the underlying regulation mechanisms involved in DKK1 expression are still unclear. In this study, we validated the expression patterns of microRNA (miR) 15a, 34a, 152, and 223 in MM cells and identified that miR-152 was significantly downregulated in the MM group compared with the non-MM group, and that miR-152 level was negatively correlated with the expression of DKK1 in the MM cells. Mechanistic studies showed that manipulating miR-152 artificially in MM cells led to changes in DKK-1 expression, and miR-152 blocked DKK1 transcriptional activity by binding to the 3'UTR of DKK1 mRNA. Importantly, we revealed that MM cells stably expressing miR-152 improved the chemotherapy sensitivity, and counteracted the bone disruption in an intrabone-MM mouse model. Our study contributes better understanding of the regulation mechanism of DKK-1 in MM, and opens up the potential for developing newer therapeutic strategies in the MM treatment.

Potential role of FLT3-ligand in the angiogenic process of multiple myeloma.
    Leukemia research, 2015, Volume: 39, Issue:12

    The aim of the study was to evaluate serum levels of FLT3-ligand (FLT3-L), a soluble molecule in bone marrow (BM), participating actively in hematopoiesis, in relation with angiogenic factors in multiple myeloma (MM) patients. We measured, in 70 patients with active MM and in 38 of them who responded to conventional therapy, serum levels of FLT3-L, along with known angiogenic factors, such as VEGF, endoglin, TNF-alpha and HGF (with ELISA) and BM microvascular density (MVD), estimating the immunohistochemical expression of CD31. All pre-treatment values were higher in active MM patients compared to controls (p<0.001 for all cases), in parallel with both International Staging System and Durie-Salmon stages (p<0.001 for all cases). Moreover, levels of FLT3-L correlated positively with all soluble angiogenic factors, as well with MVD (p<0.0001 for all cases). Post-treatment values of FLT3-L decreased significantly in responders to therapy (p<0.001). The underlying relation of MM angiogenesis with FLT3-L may result from the fact that BM microvasculature is a major source of FLT3-L, both in BM niche and probably in peripheral blood. Our results suggest that serum levels of FLT3-L may be used as angiogenic marker in MM patients.

Multiple myeloma: a descriptive study of 217 Egyptian patients.
    Annals of hematology, 2014, Volume: 93, Issue:1

    Multiple myeloma is a neoplasm of plasma cells that results in the overproduction of light and heavy chain monoclonal immunoglobulins. The incidence rate increases with age, particularly after 40 years, and is higher in men. To determine the clinical and laboratory characteristics and survival of diagnosed Egyptian multiple myeloma patients admitted to the Haemato-Oncology Department between 2000 and 2010. Records of all patients in whom multiple myeloma was diagnosed at the Kasr Al Aini Hospital between 2000 and 2010 were included in this retrospective study. The mean age of patients was 58.5 years (range, 27-80 years). Fifty-nine percent were males. The majority of patients (73 %) had an immunoglobulin G monoclonal band and 70 % were Kappa chain-positive. Mean overall survival was 37.5 months (range, 1-84 months). Survival analysis was statistically insignificant with respect to age, sex, International Staging System and type of treatment (p > 0.05). Our records were largely comparable to those reported in Chinese studies but different from those noted in Western and Arabic countries.

Addition of thalidomide to melphalan and prednisone treatment prolongs survival in multiple myeloma--a retrospective population based study of 1162 patients.
    European journal of haematology, 2014, Volume: 92, Issue:1

    The combination of melphalan and prednisone (MP) has been the standard treatment of multiple myeloma (MM). Since the introduction of novel agents, the clinical outcome in MM has improved. Six randomized prospective studies with thalidomide combined with melphalan and prednisone (MPT) compared to MP have been performed, most of them showing that MPT gives a better response rate and median overall survival (OS). Amongst 1843 MM patients admitted to 15 Swedish centres, we selected all patients treated with MP and MPT in first, second, third or fourth line of therapy, in total 888 patients treated with MP and 274 with MPT. Patients were evaluated for response rate, OS and Time to Next Treatment. Multivariate Cox model analysis was made to adjust for different criteria at time for MM-diagnosis. The median OS from beginning of first line of treatment was 2.2/4.2 yrs after MP/MPT respectively, and in second, third and fourth line of treatment 1.8/2.9, 1.4/1.6 and 1.1/1.9 yrs (P < 0.0001, 0.003, 0.74 and 0.235). The relative risk for death in the MPT group vs. the MP group was 0.61 (95% CI: 0.45-0.84) in first and 0.55 (0.38-0.83), P < 0.01) in second line. Treatment with MPT gave a significantly better OS rate after both first and second line of therapy when compared with treatment with MP only.

Differential humoral responses against heat-shock proteins after autologous stem cell transplantation in multiple myeloma.
    Annals of hematology, 2014, Volume: 93, Issue:1

    Heat-shock proteins (HSP) are important molecules in the pathogenesis of multiple myeloma (MM). Their blockages by drugs or cellular immune response have been investigated, and a possible association with the presence of oligoclonal bands (OB) has been postulated in patients with MM after allogenic stem cell transplantation. The aim of the present study was to ascertain the serum antibody levels against three HSP (60, 70 and 90) by ELISA in patients with MM in complete remission after autologous stem cell transplantation (ASCT), with or without OB, and compare them with those patients with stable gammopathy of undetermined significance (MGUS) and healthy controls. Our results in samples after ASCT showed no differential levels of anti-HSP according to the presence or absence of the oligoclonal response. However, higher levels of anti-HSP90 were found in patients with stable MGUS in comparison with MM patients (p = 0.004). In the same line, a longer progression-free survival was observed in those patients who presented higher anti-HSP90 levels after ASCT (p = 0.042). These results suggest, for first time, the potential of anti-HSP90 humoral immune response for long-term control of malignant plasma cell disorders.

By inhibiting Src, verapamil and dasatinib overcome multidrug resistance via increased expression of Bim and decreased expressions of MDR1 and survivin in human multidrug-resistant myeloma cells.
    Leukemia research, 2014, Volume: 38, Issue:1

    The calcium channel blocker verapamil inhibits the transport function of multidrug resistance protein 1 (MDR1). Although verapamil acts to reverse MDR in cancer cells, the underlying mechanism remains unclear. In the present study, we investigated the mechanism of reversing MDR by verapamil in anti-cancer drug-resistant multiple myeloma (MM) cell lines. We found that verapamil suppresses MDR1 and survivin expressions and increases Bim expression via suppression of Src activation. Furthermore, dasatinib reversed the drug-resistance of the drug-resistant cell lines. These findings suggest that Src inhibitors are potentially useful as an anti-MDR agent for the treatment of malignant tumor cells.

Bortezomib, melphalan, prednisone (VMP) versus melphalan, prednisone, thalidomide (MPT) in elderly newly diagnosed multiple myeloma patients: A retrospective case-matched study.
    American journal of hematology, 2014, Volume: 89, Issue:4

    Novel agents in combination with melphalan and prednisone (MP) significantly improved progression-free survival (PFS) and overall survival (OS) in multiple myeloma (MM). Randomized trials comparing MP plus bortezomib (VMP) versus MP plus thalidomide (MPT) are lacking. Nine hundred and fifty-six elderly (>65 years) newly diagnosed MM patients from six European randomized trials were retrospectively analyzed and matched for age, albumin, and beta2-microglobulin at diagnosis, 296 patients were selected from the VMP groups, and 294 from MPT. Complete response rate was 21% in the VMP patients and 13% in the MPT patients (P = 0.007). After a median follow-up of 34 months (range, 1-92), VMP significantly prolonged both PFS (median 32.5 vs. 22.9 months, HR 0.65; 95% CI 0.52-0.82; P < 0.001) and OS (median 79.7 vs. 45.1 months, HR 0.44; 95% CI 0.32-0.59; P < 0.001) in comparison with MPT. The benefit in terms of OS of the VMP group was quite similar among patients with different risk factors defined by sex, ISS, ECOG performance status, or serum creatinine but not among patients ≥ 75 years. Multivariate analysis confirmed that VMP was an independent predictor of longer PFS and OS. In a control-case matched analysis, PFS and OS were prolonged in patients who received VMP in comparison with those treated with MPT.

Bendamustine and melphalan kill myeloma cells similarly through reactive oxygen species production and activation of the p53 pathway and do not overcome resistance to each other.
    Leukemia & lymphoma, 2014, Volume: 55, Issue:9

    Because the old alkylating drug bendamustine (BDM) is currently under evaluation in patients with multiple myeloma, we compared its efficacy to that of melphalan in 29 human myeloma cell lines (HMCLs). The concentrations of BDM and melphalan that killed 50% of cells (LD50) in HMCLs were linearly correlated (p < 0.001), and reactive oxygen (ROS) scavengers similarly inhibited cell death induced by both drugs. Sensitivity of HMCLs to both drugs was correlated to p53: the BDM and melphalan median LD50 values of TP53(wild-type) HMCLs were more than two-fold lower than those of TP53(abnormal) HMCLs (p < 0.001), and p53 silencing in TP53(wt) NCI-H929 cells inhibited BDM- and melphalan-induced cell death. Both drugs induced expression of p53 targets, p21, Puma and DR5, only in TP53(wt) HMCLs. In primary cells, both drugs induced an increase in DR5 expression in cells without del(17p). Finally, we demonstrated that the combined effect of BDM and melphalan was additive, and that BDM did not overcome melphalan resistance and vice versa.

High-dose chemotherapy and autologous stem cell transplantation in multiple myeloma: a single institution experience at All India Institute of Medical Sciences, New Delhi, using non-cryopreserved peripheral blood stem cells.
    Clinical lymphoma, myeloma & leukemia, 2014, Volume: 14, Issue:2

    Intravenous high-dose melphalan has a short half-life, and application of this single drug in MM transplant favors the use of stem cells without cryopreservation, for wider use in general and in resource-limited settings in particular.. Ninety-two patients with MM were given high-dose melphalan and rescued with granulocyte colony stimulating factor (G-CSF) mobilized noncryopreserved autologous PBSC, in our hospital during the past 18 years. Stem cells were mobilized with 4 days of G-CSF, harvested (median CD34 dose, 2.9 × 10(6)/kg) and then stored at 4°C in a refrigerator for a median of 2 days (range, 1-5 days) before reinfusion.. Median time to neutrophil (> 500/mm(3)) and platelet (> 20,000/mm(3)) engraftment were 10 and 14 days respectively. There was no graft failure. Mucositis grade 3/4 was seen in 66 patients (72%). Transplant-related mortality at 100 days was 3.2%. The overall response to transplant was 88% and improvement compared with pretransplant status was seen in 48%. The median overall survival (OS) and progression-free survival (PFS) were 61.7 months and 35.4 months respectively; independent predictors of survival were Eastern Cooperative Oncology Group Performance Status and hemoglobin for OS and chemosensitive disease and remission status after transplant for PFS.. We conclude that high-dose chemotherapy and autologous transplant with noncryopreserved PBSC is a simple, effective, and safe method for MM with equivalent results, and that cryopreservation is not necessary. It reduces the cost of transplant and avoids dimethyl sulfoxide toxicity.

Hematopoietic cell transplant comorbidity index is predictive of survival after autologous hematopoietic cell transplantation in multiple myeloma.
    Biology of blood and marrow transplantation : journal of the American Society for Blood and Marrow Transplantation, 2014, Volume: 20, Issue:3

    Autologous hematopoietic stem cell transplantation (AHCT) improves survival in patients with multiple myeloma (MM) but is associated with morbidity and nonrelapse mortality (NRM). Hematopoietic cell transplant comorbidity index (HCT-CI) was shown to predict risk of NRM and survival after allogeneic transplantation. We tested the utility of HCT-CI as a predictor of NRM and survival in patients with MM undergoing AHCT. We analyzed outcomes of 1156 patients of AHCT after high-dose melphalan reported to the Center for International Blood and Marrow Transplant Research. Individual comorbidities were prospectively collected at the time of AHCT. The impact of HCT-CI and other potential prognostic factors, including Karnofsky performance score (KPS), on NRM and survival were studied in multivariate Cox regression models. HCT-CI score was 0, 1, 2, 3, and >3 in 42%, 18%, 13%, 13%, and 14% of the study cohort, respectively. Subjects were stratified into 3 risk groups: HCT-CI score of 0 (42%) versus HCT-CI score of 1 to 2 (32%) versus HCT-CI score > 2 (26%). Higher HCT-CI was associated with lower KPS < 90 (33% of subjects score of 0 versus 50% in HCT-CI score > 2). HCT-CI score > 2 was associated with melphalan dose reduction (22% versus 10% in score 0 cohort). One-year NRM was low at 2% (95% confidence interval, 1% to 4%) and did not correlate with HCT-CI score (P = .9). On multivariate analysis, overall survival was inferior in groups with HCT-CI score of 1 to 2 (relative risk, 1.37, [95% confidence interval, 1.01 to 1.87], P = .04) and HCT-CI score > 2 (relative risk, 1.5 [95% confidence interval, 1.09 to 2.08], P = .01). Overall survival was also inferior with KPS < 90 (P < .001), IgA subtype (P ≤ .001), those receiving >1 pretransplant induction regimen (P = .007), and those with resistant disease at the time of AHCT (P < .001). AHCT for MM is associated with low NRM, and death is predominantly related to disease progression. Although a higher HCT-CI score did not predict NRM, it was associated with inferior survival.

Functional analysis of the involvement of apurinic/apyrimidinic endonuclease 1 in the resistance to melphalan in multiple myeloma.
    BMC cancer, 2014, Jan-08, Volume: 14

    Melphalan resistance has been considered one of the major obstacles to improve outcomes in multiple myeloma (MM) therapy; unfortunately, the mechanistic details of this resistance remain unclear. Melphalan is a highly effective alkylating agent which causes many types of DNA lesions, including DNA base alkylation damage that is repaired by base excision repair (BER). We postulated that human apurinic/apyrimidinic endonuclease 1 (APE1), an essential BER enzyme, plays a vital role in acquired melphalan resistance. However, because APE1 is a multifunctional protein with redox activity and acetylation modification in addition to its major repair activity, the particular APE1 function that may play a more important role in melphalan resistance is unknown.. Two MM cell lines, RPMI-8226 and U266 were used to measure the difference in APE1 levels in melphalan-resistant and sensitive derivatives. APE1 functional mutants for DNA repair, redox and acetylation were employed to investigate the roles of individual APE1 activities in acquired melphalan resistance.. Our results indicate that APE1 is overexpressed in both MM melphalan-resistant cells. Knocking down APE1 sensitizes the melphalan resistant MM cells to melphalan treatment. The exogenous expression of DNA repair mutant H309N and acetylation mutant K6R/K7R of APE1 failed to restore the melphalan resistance of the APE1 knockdown RPMI-8226 cells. The AP endonuclease activity and multidrug resistance protein 1 (MDR1) regulatory activity may play roles in the melphalan resistance of MM cells.. The present study has identified that the DNA repair functions and the acetylation modification of APE1 are involved in melphalan resistance of MM cells and has also shed light on future therapeutic strategies targeting specific APE1 functions by small molecule inhibitors.

Induction of chemoresistance by all-trans retinoic acid via a noncanonical signaling in multiple myeloma cells.
    PloS one, 2014, Volume: 9, Issue:1

    Despite the successful application of all-trans retinoic acid (ATRA) in multiple myeloma treatment, ATRA-induced chemoresistance in the myeloma patients is very common in clinic. In this study, we evaluated the effect of ATRA on the expression of apurinic endonuclease/redox factor-1 (Ape/Ref-1) in the U266 and RPMI-8226 myeloma cells to explore the chemoresistance mechanism involved. ATRA treatment induced upregulation of Ape/Ref-1 via a noncanonical signaling pathway, leading to enhanced pro-survival activity counteracting melphalan (an alkylating agent). ATRA rapidly activated p38-MSK (mitogen- and stress activated protein kinase) cascade to phosphorylate cAMP response element-binding protein (CREB). Phosphorylated CREB was recruited to the Ape/Ref-1 promoter to evoke the gene expression. The stimulation of ATRA on Ape/Ref-1 expression was attenuated by either p38-MSK inhibitors or overexpression of dominant-negative MSK1 mutants. Moreover, ATRA-mediated Ape/Ref-1 upregulation was correlated with histone modification and activation of CBP/p300, an important cofactors for CREB transcriptional activity. C646, a competitive CBP/p300 inhibitor, abolished the upregulation of Ape/Ref-1 induced by ATRA. Intriguingly, CBP rather than p300 played a dominant role in the expression of Ape/Ref-1. Hence, our study suggests the existence of a noncanonical mechanism involving p38-MSK-CREB cascade and CBP induction to mediate ATRA-induced Ape/Ref-1 expression and acquired chemoresistance in myeloma cells.

Long-term results in multiple myeloma after high-dose melphalan and autologous transplantation according to response categories in the era of old drugs.
    Clinical lymphoma, myeloma & leukemia, 2014, Volume: 14, Issue:2

    The aim of this study was to investigate the correlation between the long-term prognosis of multiple myeloma (MM) and the quality of response to therapy in a cohort of 173 patients treated with high-dose melphalan (HDM) and autologous transplantation in the era of old drugs.. A total of 173 patients with de novo MM who received a transplant between 1994 and 2010 were analyzed. VAD (vincristine, doxorubicin [Adriamycin], dexamethasone) was used as front-line regimen before auto-HPCT. The conditioning was HDM 200 mg/m(2). Patients were evaluated for clinical response using the criteria from the European Group for Blood and Marrow Transplantation, modified to include near complete remission (nCR) and very good partial remission (VGPR).. The response distribution after transplantation in our series was complete remission (CR) in 33 cases (19%), nearly complete remission (nCR) in 38 cases (22%), VGPR in 30 cases (17%), partial remission (PR) in 65 cases (38%), and stable disease (SD) in 7 cases (4%). Patients were followed for 48 ± 36 months. Median overall survival (OS) was not reached for the CR group. Progression-free survival (PFS) was 122 months for CR, 55 months for nCR, 56 months for VGPR, 32 months for PR, and 22 months for SD. Significant differences in PFS and OS were found between the CR and nCR groups (P = .003 and P = .001, respectively), between the CR and VGPR groups (P = .002 and P = .001, respectively), and between the CR and PR groups (P = .000 and P = .001, respectively). Responses were clustered in 3 main categories, ie, CR, nCR + VGPR + PR, and SD. The respective 10-year PFS and OS values were 58% and 70% for CR, 15% and 18% for nCR + VGPR + PR, and 0% and 0% for SD.. The achievement of depth and prolonged response represents the most important prognostic factor. The relapse rate is low for patients in CR after 10 years of follow-up, possibly signifying a cure.

Three cost effectiveness models for the treatment of multiple myeloma, were compared that had been developed to inform resource allocation in the UK for the chemotherapy regimens bortezomib, melphalan and prednisolone (BMP); and melphalan, prednisolone and thalidomide (MPT) versus melphalan and prednisolone (MP). The models used alternative approaches and assumptions to estimate the overall survival and progression-free survival for each of the interventions. Through the use of sensitivity analyses, the most influential parameters and assumptions of each of the models were identified.. The models developed by the manufacturers gave conflicting results, with each manufacturer favouring their drug. The differences between the model results were determined by two parameters: the hazard ratio for overall survival for MPT vs. MP and the cost of bortezomib.. Using models developed for assessing treatments for multiple myeloma we demonstrated that it was feasible to compare models, which then aided decision makers in making reimbursement decisions.

A novel TLR-9 agonist C792 inhibits plasmacytoid dendritic cell-induced myeloma cell growth and enhance cytotoxicity of bortezomib.
    Leukemia, 2014, Volume: 28, Issue:8

    Our prior study in multiple myeloma (MM) patients showed increased numbers of plasmacytoid dendritic cells (pDCs) in the bone marrow (BM), which both contribute to immune dysfunction as well as promote tumor cell growth, survival and drug resistance. Here we show that a novel Toll-like receptor (TLR-9) agonist C792 restores the ability of MM patient-pDCs to stimulate T-cell proliferation. Coculture of pDCs with MM cells induces MM cell growth; and importantly, C792 inhibits pDC-induced MM cell growth and triggers apoptosis. In contrast, treatment of either MM cells or pDCs alone with C792 does not affect the viability of either cell type. In agreement with our in vitro data, C792 inhibits pDC-induced MM cell growth in vivo in a murine xenograft model of human MM. Mechanistic studies show that C792 triggers maturation of pDCs, enhances interferon-α and interferon-λ secretion and activates TLR-9/MyD88 signaling axis. Finally, C792 enhances the anti-MM activity of bortezomib, lenalidomide, SAHA or melphalan. Collectively, our preclinical studies provide the basis for clinical trials of C792, either alone or in combination, to both improve immune function and overcome drug resistance in MM.

The lymphoma-like polychemotherapy regimen "Dexa-BEAM" in advanced and extramedullary multiple myeloma.
    Annals of hematology, 2014, Volume: 93, Issue:7

    Extramedullary disease (EMD) in multiple myeloma (MM) is characterised by an aggressive biology and an adverse prognosis especially when occurring at relapse. Due to the high proliferation found in EMD lesions, we analysed outcome data of patients treated with a lymphoma-type therapy not based on novel compounds, the Dexa-BEAM protocol. Retrospective analysis of MM patients having received Dexa-BEAM (including dexamethasone, carmustine, cytarabine, etoposide and melphalan) at our institution from January 2007 to November 2012. In all, 18 patients were identified, 11 of whom had EMD. Objective response (≥PR) to Dexa-BEAM was achieved in more than half of the patients with EMD (6/11); consecutive high-dose consolidation strategy with autologous or allogeneic stem cell transplantation improved upon the depth of remission in two thirds of EMD patients (4/6) with ongoing remissions in three patients. In contrast, all patients without consolidation relapsed. Progression-free survival after Dexa-BEAM was short in both patient groups with intramedullary or extramedullary myeloma with a median of 3 and 4 months, respectively. Toxicity was relevant with one treatment-related death and grades 3 and 4 toxicities in all 18 patients. Dexa-BEAM is an effective induction regimen in medically fit patients with extramedullary manifestations to regain disease control prior to an intended autologous or allogeneic transplantation.

Limited value of the international staging system for predicting long-term outcome of transplant-ineligible, newly diagnosed, symptomatic multiple myeloma in the era of novel agents.
    International journal of hematology, 2014, Volume: 99, Issue:4

    We retrospectively investigated clinical outcomes and prognostic factors of 131 patients with transplant-ineligible newly diagnosed multiple myeloma (NDMM) who received melphalan and prednisolone (MP) as first-line therapy from 2006 to 2013. Eighty-one patients received salvage therapies incorporating bortezomib, lenalidomide, and/or thalidomide. The overall response rate to MP was 54.2 %, including 9.2 % of better than very good partial response. With a median follow-up period of 30.2 months, median overall survival (OS) and median time to next treatment (TNT) were 54.4 and 19.0 months, respectively. Univariate analysis revealed that performance status and serum calcium level significantly associated with both OS and TNT, and multivariate analysis revealed that the higher serum calcium level had a significantly unfavorable impact on OS and TNT. Importantly, staging informed by the international staging system (ISS) was not predictive for OS or TNT in the analyzed cohort. Our study revealed that, in the context of first-line MP therapy for NDMM, the salvage therapy incorporating novel agents produced a survival period of >30 months after the initiation of second-line therapy, suggesting that the predictive value of ISS for OS and TNT may be limited in the era of novel agents.

The choice of multiple myeloma induction therapy affects the frequency and severity of oral mucositis after melphalan-based autologous stem cell transplantation.
    Clinical lymphoma, myeloma & leukemia, 2014, Volume: 14, Issue:4

    Mucositis is a common complication of high-dose melphalan (HDM) used before autologous stem cell transplantation (ASCT) for multiple myeloma (MM). Mucositis rates are influenced by previous chemotherapy (CT) exposure. We examined the effect of induction therapy before ASCT on ASCT mucositis rates.. Patients undergoing first 200 mg/m(2) HDM ASCT were assessed. Those receiving < 200 mg/m(2), or those with previous ASCT were excluded. Patients were evaluated depending on type of induction therapy (CT, immunomodulatory drug [IMiD], or proteasome inhibitor [PI]) before ASCT. A case record review was performed and data collected on response to induction, rates of Grade 3/4 mucositis, and days of total parenteral nutrition (TPN) or parenteral opiate analgesia.. One hundred twenty-eight patients with ASCT were assessed. Induction therapy was CT- (n = 62), IMiD- (n = 51), or PI-based (n = 15) therapy. Patient characteristics were overall similar, including median age, MM stage, and CD34(+) cell dose. IMiD-based therapy patients had lower rates of mucositis (33% vs. 53%; P = .03) and less opiate requirements (10% vs. 31%; P = .02) compared with those treated with CT. Rates of mucositis and opiate use in the PI group were not different to the CT cohorts (33% vs. 53%; P = .6 and 13% vs. 31%; P = .13), likely due to concurrent anthracycline exposure. TPN usage was similar (CT, 42%; IMiD, 35%; and PI, 20%), as was neutropenia duration and antibiotic usage.. Patients treated with IMiD-based regimens before HDM ASCT had significantly lower rates of mucositis than those treated with CT-based therapy. There were too few patients who received PI therapy to evaluate the effect.

Phenotypic, genomic and functional characterization reveals no differences between CD138++ and CD138low subpopulations in multiple myeloma cell lines.
    PloS one, 2014, Volume: 9, Issue:3

    Despite recent advances in the treatment of multiple myeloma (MM), it remains an incurable disease potentially due to the presence of resistant myeloma cancer stem cells (MM-CSC). Although the presence of clonogenic cells in MM was described three decades ago, the phenotype of MM-CSC is still controversial, especially with respect to the expression of syndecan-1 (CD138). Here, we demonstrate the presence of two subpopulations--CD138++ (95-99%) and CD138low (1-5%)--in eight MM cell lines. To find out possible stem-cell-like features, we have phenotypically, genomic and functionally characterized the two subpopulations. Our results show that the minor CD138low subpopulation is morphologically identical to the CD138++ fraction and does not represent a more immature B-cell compartment (with lack of CD19, CD20 and CD27 expression). Moreover, both subpopulations have similar gene expression and genomic profiles. Importantly, both CD138++ and CD138low subpopulations have similar sensitivity to bortezomib, melphalan and doxorubicin. Finally, serial engraftment in CB17-SCID mice shows that CD138++ as well as CD138low cells have self-renewal potential and they are phenotypically interconvertible. Overall, our results differ from previously published data in MM cell lines which attribute a B-cell phenotype to MM-CSC. Future characterization of clonal plasma cell subpopulations in MM patients' samples will guarantee the discovery of more reliable markers able to discriminate true clonogenic myeloma cells.

Comparison of 1-day vs 2-day dosing of high-dose melphalan followed by autologous hematopoietic cell transplantation in patients with multiple myeloma.
    Bone marrow transplantation, 2014, Volume: 49, Issue:6

    High-dose melphalan at 200 mg/m(2) can be administered in 1 day or over 2 consecutive days before autologous hematopoietic cell transplantation (HCT) for multiple myeloma (MM). Limited data exist on the comparison of the two dosing schedules. A retrospective study of 278 consecutive MM patients receiving high-dose melphalan from January 2010 to December 2012 was conducted. Objectives were to compare the length of hospitalization, toxicity profile, response rates, PFS and OS. One hundred and eighty five patients received 2-day dosing and 93 received 1-day dosing. The two end points of the 95% confidence interval (CI) for the difference did not exceed the preselected margin, therefore the length of hospitalization was considered equivalent. No significant differences were found for response rates, PFS and OS.  The toxicity profile was similar with the exception of more frequent ⩾grade 3 oral mucositis in the 2-day group (13.5% vs 5.4%; odds ratio 3.07 (95% CI:1.11-8.48); P=0.03). High-dose melphalan, given either in 1 day or over 2 days, produced comparable treatment outcomes except for increased grade 3/4 mucositis in the 2-day regimen. One-day dosing could shorten the hospital stay by 1 day and may allow better resource utilization.

Expression of cereblon protein assessed by immunohistochemicalstaining in myeloma cells is associated with superior response of thalidomide- and lenalidomide-based treatment, but not bortezomib-based treatment, in patients with multiple myeloma.
    Annals of hematology, 2014, Volume: 93, Issue:8

    Cereblon (CRBN) is essential for the anti-myeloma (MM) activity of immunomodulatory drugs (IMiDs), such as thalidomide and lenalidomide. However, the clinical implications of CRBN in MM patients are unclear. Using immunohistochemical (IHC) staining on paraffin-embedded bone marrow sections, the expression of CRBN protein in myeloma cells (MCs) was assessed in 40 relapsed/refractory MM (RRMM) patients who received lenalidomide/dexamethasone (LD) and 45 and 22 newly diagnosed MM (NDMM) patients who received thalidomide/dexamethasone (TD) and melphalan/bortezomib/prednisolone (MVP), respectively. IHC staining were scored on a scale representing the diffuseness and intensity of positive-staining MCs (range, 0-8) and a score ≥4.5 was used for CRBN positivity (CRBN(+)) on a cut-point analysis of all possible scores and response of TD and LD. Compared to CRBN(+) NDMM patients, CRBN(-) NDMM patients had more international staging system (ISS) III (26 vs. 61 %, respectively; P = 0.006). In the LD and TD cohorts, the response rate (RR) was higher in CRBN(+) patients than CRBN(-) patients (LD 79 vs. 33 %, respectively; P = 0.005) (TD 75 vs. 29 %, respectively; P = 0.005); however, this trend was not observed in the MVP cohort. In the LD and TD cohorts, the positive and negative prediction value of CRBN(+) for treatment response was 79 and 67 % and 75 and 71 %, respectively. Multivariate analysis showed that CRBN(+) was a significant factor associated with superior RR for LD and TD. The data suggest that expression of CRBN protein in MCs assessed using the IHC is a feasible approach to predict the response of IMiDs in MM patients.

A single nucleotide polymorphism in SLC7A5 is associated with gastrointestinal toxicity after high-dose melphalan and autologous stem cell transplantation for multiple myeloma.
    Biology of blood and marrow transplantation : journal of the American Society for Blood and Marrow Transplantation, 2014, Volume: 20, Issue:7

    Multiple myeloma is the most frequent indication for high-dose melphalan (HDM) chemotherapy with autologous stem cell transplantation (ASCT). Gastrointestinal symptoms represent the most significant nonhematological toxicity of HDM. However, specific, especially genetic, predictors of their incidence or clinical severity are lacking. The amino acid transporters LAT1 and LAT2 encoded by the SLC7A5 and SLC7A8 genes, respectively, are the principal mediators of melphalan uptake into cells. To determine whether genetic variability at these loci contributed to interindividual differences in the development of gastrointestinal complications of HDM, we analyzed single nucleotide polymorphisms (SNPs) in these genes in 135 patients with multiple myeloma treated with HDM and ASCT and correlated these with the need for total parenteral nutrition (TPN). Seven SNPs in SLC7A5 and 20 in SLC7A8 were genotyped. Multiple analyses indicated that 1 SNP in the first intron of SLC7A5, rs4240803, was significantly associated with TPN use (odds ratio = .45, 95% confidence interval, .25 to .79; P = .007). Further, every haplotype that correlated with TPN requirement included this SNP. These results suggest that variability in melphalan transport affects mucosal injury after HDM. This finding could help in individualizing the dose of this effective and widely used chemotherapeutic agent for multiple myeloma.

Age is a prognostic factor even among patients with multiple myeloma younger than 66 years treated with high-dose melphalan: the IFM experience on 2316 patients.
    Haematologica, 2014, Volume: 99, Issue:7

    Age is a strong prognostic factor in multiple myeloma. The overall survival is shorter in patients older than 66 years, and even shorter in those older than 75 years. Whether age is also a prognostic parameter in patients younger than 66 years treated homogeneously with intensive approaches is unknown. To address this issue, we retrospectively analyzed a series of 2316 patients treated homogeneously with 3-4 cycles of induction chemotherapy followed by a high-dose melphalan course, without any consolidation or maintenance. We show that patients older than 60 years have a statistically significant shorter overall survival. The analysis of prognostic parameters did not show a higher incidence of high-risk cytogenetics, but a higher incidence of International Staging System (ISS) stages 2 and 3, mainly due to higher β2-microglobulin levels. This study is the first to demonstrate the impact of age in the outcome of 'young' patients with multiple myeloma, and suggests that this parameter should be included in the stratification factors for future prospective clinical trials.

Clinical features, outcome, and prognostic factors for survival and evolution to multiple myeloma of solitary plasmacytomas: a report of the Greek myeloma study group in 97 patients.
    American journal of hematology, 2014, Volume: 89, Issue:8

    Solitary plasmacytoma (SP) is a rare plasma cell dyscrasia characterized by the presence of bone or extramedullary plasma cell tumors. The treatment of choice is local radiotherapy (R/T) ± surgical excision. The role of adjuvant chemotherapy (C/T) or novel agents (NA) is uncertain. Data related to prognostic factors are inconclusive. Herein, we describe the clinical features, survival and prognosis of 97 consecutive patients, 65 with bone SP (SBP), and 32 with extramedullary SP (SEP), diagnosed and treated in 12 Greek Myeloma Centers. Objective response rate (≥PR) and complete response (CR) was 91.8% and 61.9%, respectively, and did not differ between the 2 groups. Overall, 38 patients relapsed or progressed to multiple myeloma (MM). After a median follow-up of 60 months, 5 and 10-year overall survival (OS) probability was 92% and 89% in SEP and 86% and 69% in SBP, respectively (P = 0.2). The 5- and 10-year MM-free survival (MMFS) probability was 90% and 70% for patients with SEP vs. 59% and 50% for patients with SBP, respectively (P = 0.054). Overall, the 5- and 10-year OS probability, plasmacytoma relapse-free survival (PRFS), progression-free survival and MMFS was 84% and 78%, 72% and 58%, 58% and 43%, and 70% and 59%, respectively. In the multivariate analysis, prolonged PRFS and young age were positive predictors of OS. Achievement of CR was the only positive predictor of PRFS. Immunoparesis was the only negative predictor of progression to MM. The addition of C/T or NA-based treatment increased toxicity without offering any survival advantage over R/T.

Comparative analysis of multiple myeloma treatment by CD138 antigen targeting with bismuth-213 and Melphalan chemotherapy.
    Nuclear medicine and biology, 2014, Volume: 41 Suppl

    Multiple myeloma (MM) is a B-cell malignancy of terminally differentiated plasma cells within the bone marrow. Despite intense research to develop new treatments, cure is almost never achieved. Alpha-radioimmunotherapy (RIT) has been shown to be effective in vivo in a MM model. In order to define where alpha-RIT stands in MM treatment, the aim of this study was to compare Melphalan, MM standard treatment, with alpha-RIT using a [213Bi]-anti-mCD138 antibody in a syngeneic MM mouse model.. C57BL/KaLwRij mice were grafted with 1 × 10(6) 5T33 murine MM cells. Luciferase transfected 5T33 cells were used for in vivo localization. The first step of the study was to assess the dose-response of Melphalan 21 days after engraftment. The second step consisted in therapeutic combination: Melphalan followed by RIT at day 22 or day 25 after engraftment. Toxicity (animal weight, blood cell counts) and treatment efficacy were studied in animals receiving no treatment, injected with Melphalan alone, RIT alone at day 22 or day 25 (3.7 MBq of [213Bi]-anti-CD138) and Melphalan combined with alpha-RIT.. Fifty percent of untreated mice died by day 63 after MM engraftment. In mice treated with Melphalan alone, only the 200 μg dose improved median survival. No animal was cured after Melphalan treatment whereas 60% of the mice survived with RIT alone at day 22 after tumor engraftment with only slight and reversible hematological radiotoxicity. No therapeutic effect was observed with alpha-RIT 25 days after engraftment. Melphalan and alpha-RIT combination does not improve overall survival compared to RIT alone, and results in increased leukocyte and red blood cell toxicity.. Alpha-RIT seems to be a good alternative to Melphalan. Association of these two treatments provides no benefit. The perspectives of this work would be to evaluate RIT impact on the regimens incorporating the novel agents bortezomide, thalidomide and lenalidomide.

Bortezomib cumulative dose, efficacy, and tolerability with three different bortezomib-melphalan-prednisone regimens in previously untreated myeloma patients ineligible for high-dose therapy.
    Haematologica, 2014, Volume: 99, Issue:6

    Substantial efficacy has been demonstrated with bortezomib-melphalan-prednisone in phase III studies in transplant-ineligible myeloma patients using various twice-weekly and once-weekly bortezomib dosing schedules. In VISTA, the regimen comprised four 6-week twice-weekly cycles, plus five 6-week once-weekly cycles. In the GIMEMA MM-03-05 study, the bortezomib-melphalan-prednisone regimen was either per VISTA ('GIMEMA twice-weekly'), or comprised nine 5-week once-weekly cycles ('GIMEMA once-weekly'). In the GEM2005MAS65 study, the regimen comprised one 6-week twice-weekly cycle, plus five 5-week once-weekly cycles. We evaluated the cumulative bortezomib dose administered during bortezomib-melphalan-prednisone, as well as efficacy and tolerability, using patient-level study data. Over all bortezomib-melphalan-prednisone cycles (nine in VISTA/GIMEMA; six in GEM2005MAS65), the median cumulative bortezomib dose administered was 38.5, 42.1, 40.3, and 32.9 mg/m(2) in VISTA, GIMEMA twice-weekly, GIMEMA once-weekly, and GEM2005MAS65, respectively, and the respective proportions of planned bortezomib dose actually delivered were 57.0%, 62.3%, 86.1%, and 90.4%. Response rates following bortezomib-melphalan-prednisone were 74-87% and appeared generally similar between studies. Three-year survival rates were 67.9-75.7% across studies. Grade 3/4 peripheral neuropathy rates were 13% in VISTA and 14% in GIMEMA twice-weekly, but were lower at 2% in GIMEMA once-weekly and 7% in GEM2005MAS65. Discontinuations and bortezomib dose reductions due to peripheral neuropathy were reduced in GIMEMA once-weekly versus VISTA and GIMEMA twice-weekly. Exclusive or predominant use of once-weekly bortezomib dosing in GIMEMA once-weekly and GEM2005MAS65 resulted in high efficacy, comparable with that demonstrated in VISTA, and similar cumulative bortezomib dose with reduced toxicity. Trials are registered with ClinicalTrials.gov: VISTA (Identifier:00111319), GIMEMA MM-03-05 (Identifier:01063179), and GEM2005MAS65 (Identifier:00443235).

Impacts of new agents for multiple myeloma on development of secondary myelodysplastic syndrome and acute myeloid leukemia.
    [Rinsho ketsueki] The Japanese journal of clinical hematology, 2014, Volume: 55, Issue:4

    The use of new agents (NAs) such as bortezomib, thalidomide, and lenalidomide has extended the survival of patients with multiple myeloma (MM). However, whether long-term treatment using NAs may increase the risk of second primary malignancies is a concern. Three hundred and thirty-three patients with MM were treated at our hospital from 1998 to 2013. Additional chromosomal abnormalities (CAs), associated with secondary myelodysplastic syndrome/acute myeloid leukemia, were observed in 13 of 152 users of NAs, but in 38 of 181 non-users of NAs. The cumulative CA incidence was higher in non-users of NAs. The CAs frequently observed were 13q-, 20q-, +8 in users of NAs, while -5/5q- and -7/7q- were detected in non-users of NAs. The total dose and treatment period of NAs did not differ between CAs-positive and -negative patients. However, a higher dose of melphalan was observed to have been used in patients who had CAs. Longer follow-up periods are necessary for an accurate risk assessment.

Usefulness and safety of oral cryotherapy in the prevention of oral mucositis after conditioning regimens with high-dose melphalan for autologous stem cell transplantation for lymphoma and myeloma.
    European journal of haematology, 2014, Volume: 93, Issue:6

    Oral mucositis (OM) is a common complication of conditioning regimens with high-dose melphalan (HDmel). This retrospective cohort study analyzes the impact of oral cryotherapy (OC) or room temperature saline rinses on the prevention of OM in patients with multiple myeloma (MM) or lymphoid neoplasias submitted to autologous stem cell transplantation (ASCT) in a single center.. From August 2006 to July 2011, 134 consecutive patients were enrolled. Two consecutive groups were included: Non-OC (August 2006 to April 2009, 68 patients) and OC (May 2009 to July 2011, 66 cases). MM cases (78, 58%) received HDmel as the conditioning regimen and 56 patients (42%) with lymphoma received BEAM.. The non-OC and OC groups were comparable for the main clinicobiologic features and type of neoplasia. OM was more frequent and severe in patients receiving BEAM as the conditioning therapy. The group of OC showed less frequent and less severe mucositis and fewer days on antibiotics. No differences were observed in the duration of OM, need for parenteral nutrition and narcotics, and the length of hospital stay on comparison with the OC and non-OC groups. By multivariate analyses, OC was an independent favorable prognostic factor for OM development.. This study shows that OC is more effective than saline rinses in the prevention of OM in patients with lymphoma and myeloma receiving conditioning regimens with HDmel for ASCT.

    Increasing evidence indicates that cancer cell stress induced by chemotherapeutic agents promote antitumor immune responses and contribute to their full clinical efficacy. In this article, we identify the signaling events underlying chemotherapy-induced NKG2D and DNAM-1 ligand expression on multiple myeloma (MM) cells. Our findings indicate that sublethal doses of doxorubicin and melphalan initiate a DNA damage response (DDR) controlling ligand upregulation on MM cell lines and patient-derived malignant plasma cells in Chk1/2-dependent and p53-independent manner. Drug-induced MICA and PVR gene expression are transcriptionally regulated and involve DDR-dependent E2F1 transcription factor activity. We also describe the involvement of changes in the redox state in the control of DDR-dependent upregulation of ligand surface expression and gene transcriptional activity by using the antioxidant agent N-acetyl-L-cysteine. Finally, in accordance with much evidence indicating that DDR and oxidative stress are major determinants of cellular senescence, we found that redox-dependent DDR activation upon chemotherapeutic treatment is critical for MM cell entry in premature senescence and is required for the preferential ligand upregulation on senescent cells, which are preferentially killed by NK cells and trigger potent IFN-γ production. We propose immunogenic senescence as a mechanism that promotes the clearance of drug-treated tumor cells by innate effector lymphocytes, including NK cells.

Immunomodulatory drugs improve the immune environment for dendritic cell-based immunotherapy in multiple myeloma patients after autologous stem cell transplantation.
    Cancer immunology, immunotherapy : CII, 2014, Volume: 63, Issue:10

    Multiple myeloma (MM) is characterized by a malignant proliferation of plasma cells in the bone marrow with associated organ damage. Although the prognosis of MM has improved recently, the disease remains incurable for the large majority of patients. The eradication of residual disease in the bone marrow is a main target on the road toward cure. Immune cells play a role in the control of cancer and can be tools to attack residual MM cells. However, the myeloma-associated immune deficiency is a major hurdle to immunotherapy. We evaluated ex vivo the effects of low doses of the immunomodulatory drugs (IMiDs) lenalidomide and pomalidomide on several immune cell types from MM patients after autologous stem cell transplantation and with low tumor burden. We observed that these drugs increased CD4(+) and CD8(+) T-cell proliferation and cytokine production, enhanced the lytic capacity of cytotoxic T lymphocytes and reduced the suppressive effects of regulatory T cells on CD8(+) T-cell responses. In addition, we found that functional dendritic cells (DCs) can be generated from mononuclear cells from MM patients. The presence of IMiDs improved the quality of antigen-specific T cells induced or expanded by these DCs as evidenced by a higher degree of T-cell polyfunctionality. Our results provide a rationale for the design of early phase clinical studies to assess the efficacy of DC-based immunotherapy in combination with posttransplant maintenance treatment with IMiDs in MM.

Clinical analysis of six cases of multiple myeloma first presenting with coagulopathy.
    Blood coagulation & fibrinolysis : an international journal in haemostasis and thrombosis, 2014, Volume: 25, Issue:6

    This is a retrospective study on six multiple myeloma patients with upfront coagulopathy and bleeding. A detailed description and analysis of clinical characteristics, coagulation factor deficiencies, treatments and outcome of those six multiple myeloma patients are presented. All six patients presented with significant bleeding. One patient was detected with single factor X deficiency and another with single factor VII (FVII) deficiency, whereas four other patients had complex factor deficiencies. The time from symptom presentation to diagnosis ranged from 3 to 10 months. After correct diagnosis and coagulation factor supplementation, those patients were treated with bortezomib/adriamycin/dexamethasone (PAD) or melphalan/dexamethasone/thalidomide (MTD) regimen. It took 29-71 days (median time 46 days) to completely correct coagulation factor deficiencies since the start of therapy for multiple myeloma. Multiple myeloma patients with acquired bleeding disorders may present with large, deep and multiple sites of haematoma or other types of significant bleeding, which may affect bone marrow examination in some of the cases. Patients may be easily misdiagnosed. The routine examinations of erythrocyte sedimentation rate, serum immunoglobulins and blood urine light chain are the key to diagnosis, hence requiring the treating physician to think broadly and look for traits suggesting myeloma as the underlying cause.

The glutathione synthesis inhibitor buthionine sulfoximine synergistically enhanced melphalan activity against preclinical models of multiple myeloma.
    Blood cancer journal, 2014, Jul-18, Volume: 4

    Melphalan (L-PAM) has been an integral part of multiple myeloma (MM) treatment as a conditioning regimen before stem cell transplant (SCT). After initial response, most treated patients experience relapse with an aggressive phenotype. Increased glutathione (GSH) in MM may mediate resistance to L-PAM. We demonstrated that the GSH synthesis inhibitor buthionine sulfoximine (BSO) synergistically enhanced L-PAM activity (inducing 2-4 logs of cell kill) against nine MM cell lines (also in the presence of marrow stroma or cytokines) and in seven primary MM samples (combination indices <1.0). In MM cell lines, BSO significantly (P<0.05) depleted GSH, increased L-PAM-induced single-strand DNA breaks, mitochondrial depolarization, caspase cleavage and apoptosis. L-PAM depleted GSH, but GSH rapidly recovered in a L-PAM-resistant MM cell line unless also treated with BSO. Treatment with N-acetylcysteine antagonized BSO+L-PAM cytotoxicity without increasing GSH. In human MM xenografted into beige-nude-xid mice, BSO significantly depleted MM intracellular GSH and significantly increased apoptosis compared with L-PAM alone. BSO+L-PAM achieved complete responses (CRs) in three MM xenograft models including maintained CRs >100 days, and significantly increased the median event-free survival relative to L-PAM alone. Combining BSO with L-PAM warrants clinical testing in advanced MM.

A novel melphalan polymeric prodrug: preparation and property study.
    Carbohydrate polymers, 2014, Oct-13, Volume: 111

    The clinical application of melphalan (Me), an anticancer drug for the treatment of hematologic malignancies, has been limited due to its poor water solubility, rapid elimination and lack of target specificity. To solve these problems, O,N-carboxymethyl chitosan-peptide-melphalan conjugates were synthesized and characterized. All polymeric prodrugs showed satisfactory water solubility. It was found that the molecular weight of O,N-carboxymethyl chitosan (O,N-CMCS) and the peptide spacer played a crucial role in controlling the drug content, diameter and drug release properties of O,N-carboxymethyl chitosan-peptide-melphalan conjugates. The studies of in vitro drug release and cell cytotoxicity by MTT assay revealed that, employing the polymeric conjugation strategy and using the peptides glycylglycine (Gly-Gly) as a spacer, the conjugates have good cathepsin X-sensitivity and lower toxicity and the drug release behavior improved remarkably. In conclusion, O,N-carboxymethyl chitosan-peptide-melphalan conjugates could be promising prodrugs for anticancer application.

Chromatin structure, transcriptional activity and DNA repair efficiency affect the outcome of chemotherapy in multiple myeloma.
    British journal of cancer, 2014, Sep-23, Volume: 111, Issue:7

    Melphalan is one of the most active chemotherapeutic agents in the treatment of multiple myeloma (MM). However, the mechanism underlying differential patient responses to melphalan therapy is unknown.. Chromatin structure, transcriptional activity and DNA damage response signals were examined following ex vivo treatment with melphalan of both malignant bone marrow plasma cells (BMPCs) and peripheral blood mononuclear cells (PBMCs) of MM patients, responders (n=57) or non-responders (n=28) to melphalan therapy. PBMCs from healthy controls (n=25) were also included in the study.. In both BMPCs and PBMCs, the local chromatin looseness, transcriptional activity and repair efficiency of the transcribed strand (TS) were significantly higher in non-responders than in responders and lowest in healthy controls (all P<0.05). Moreover, we found that melphalan-induced apoptosis inversely correlated with the repair efficiency of the TS, with the duration of the inhibition of mRNA synthesis, phosphorylation of p53 at serine 15 and apoptosis rates being higher in responders than in non-responders (all P<0.001).. Our findings provide a mechanistic basis for the link between DNA repair efficiency and response to melphalan therapy. Interestingly, the observation of these phenomena in PBMCs provides a novel approach for the prediction of response to anti-myeloma therapy.

Bortezomib-based chemotherapy regimens can improve response in newly diagnosed multiple myeloma patients with bcl-2 and survivin overexpression.
    International journal of clinical and experimental pathology, 2014, Volume: 7, Issue:7

    To investigate the relationship between the Bcl-2 and survivin expression and the different regimens therapeutic efficacy newly diagnosed multiple myeloma (NDMM).. We retrospectively assessed the association of Bcl-2 and survivin expression with chemotherapeutic efficacy and prognosis in 59 NDMM patients in a single center.. The positive expression rate for survivin and Bcl-2 was 35% and 74%, respectively. Survivin and Bcl-2 protein expression were not associated with clinical stage, suggesting that they are not related to tumor burden in NDMM. Bortezomib-based regimens were more effective in reducing tumor burden and achieving therapeutic (complete and partial) response compared with non-bortezomib-based regimens irrespective of Bcl-2 or survivin expression (P < 0.05). In cases with both negative Bcl-2 and survivin expression (Bcl-2(-)survivin(-)), the response to bortezomib and non-bortezomib-based regimens was similar (p = 0.429). Bcl-2 and survivin expression were not correlated with overall survival (OS); however, Bcl-2-survivin- cases showed a trend towards a longer OS (P = 0.078).. We recommend bortezomib-containing regimens for NDMM with single or double-positive Bcl-2 and survivin expression.

Extramedullary progression of multiple myeloma despite concomitant medullary response to multiple combination therapies and autologous transplant: a case report.
    Journal of medical case reports, 2014, Sep-08, Volume: 8

    Extramedullary myeloma that occurs during the clinical course of multiple myeloma is rare but is an independent poor prognostic factor with mortality of 73% and median survival of 12 months despite aggressive therapies including novel agents. The clinicopathological aspects, biology and management of extramedullary myelomas are poorly understood. Our case highlights the pathobiological aspects of this important but rare entity, and the repercussions of modern therapies.. A 60-year-old Caucasian man initially presented with an anterior rib fracture. Subsequent workup revealed stage IIIB immunoglobulin G lambda multiple myeloma. A bone marrow biopsy showed sheets of plasma cells, harboring unfavorable cytogenetics including deletion of 17p and t(4;14). He achieved near complete remission and resolution of karyotypic abnormalities with three cycles of induction doxorubicin, thalidomide, and dexamethasone (clinical trial). This was followed by high-dose melphalan and autologous stem cell transplant. He relapsed 1 year later. His bone marrow at that time showed only a few scattered polyclonal plasma cells. He received three cycles of bortezomib and tanespimycin (clinical trial) and achieved very good partial response. He again relapsed 1 year later with multiple large peripheral soft tissue masses and lymph nodes. Biopsies of the peripheral lesions were consistent with extramedullary myeloma, but repeat bone marrow biopsy continued to show no evidence of intramedullary disease.. This is one of the few cases reported that illustrates the differential response of extramedullary compared to intramedullary myeloma to multiple standard combination therapies including novel therapeutics and transplant, resulting in a very short survival. Several mechanisms for intra-to-extra medullary migration and hence the differential treatment response have been hypothesized. Physicians should be aware of this problem during treatment with immunomodulatory drugs and proteasome inhibitors not only in relapsed but also in front-line setting. In such cases, there is a potential role for evolving targeted therapeutics as we continue to better understand the tumor biology.

Treatment of Non-transplant patients with multiple myeloma: routine treatment by office-based haematologists in Germany--data from the prospective Tumour Registry Lymphatic Neoplasms (TLN).
    Oncology research and treatment, 2014, Volume: 37, Issue:11

    Various treatment options exist for patients with multiple myeloma (MM). Clinical registries provide insight into routine treatment and identify changes in treatment over time.. The Tumour Registry Lymphatic Neoplasms (TLN) prospectively collects data on the treatment of patients with lymphoid B cell neoplasms as administered by office-based haematologists in Germany. Data on patient and tumour characteristics, comorbidities, systemic treatments and outcome parameters are recorded.. 371 non-transplant patients with MM were recruited between 2009 and 2011. At the start of first-line (second-line) treatment, the median age was 73 (75) years; 67% (74%) of the patients had stage III MM (classification of Durie and Salmon) and 19% (28%) had renal insufficiency. In the first line, 40% of the patients received bortezomib+melphalan+prednisone (VMP), 25% received bortezomib±dexamethasone (V±D) and 8% were treated with melphalan+prednisone+thalidomide (MPT). While use of bortezomib-based regimens increased from 67% (2009) to 85% (2011), use of melphalan-based regimens decreased from 68% to 48%. The overall objective response rate of treatment was 82%. In the second line, 34% of the patients received V±D and 16% lenalidomide+dexamethasone (LD).. Bortezomib-based regimens dominate the first- and second-line treatment of MM. Future analyses will investigate outcome data, e.g. effectiveness of bortezomib retherapy compared to other second-line treatments.

Thrombotic thrombocytopenic purpura due to anti-ADAMTS13 antibodies in multiple myeloma.
    Clinical nephrology, 2014, Volume: 81, Issue:3

    Thrombotic thrombocytopenic purpura (TTP) is a particularly serious form of thrombotic microangiopathy (TMA) due to the risk of multiple organ dysfunction. Several etiological factors such as infection, auto-immune disease, certain medications and cancers have been associated with TTP.. A 74-year-old hypertensive woman with a history of thromboembolic disease was hospitalized for acute kidney injury (AKI) associated with pneumonia. Initial investigations were suggestive of Pneumocystis jirovecii infection and myeloma cast nephropathy. Several days later, the patient presented features of TTP. Von Willebrand factor-cleaving protease activity was less than 5% with a high level of IgG antibody directed against ADAMTS13. Treatment consisted of monthly 4-day cycles of dexamethasone and melphalan in combination with plasmapheresis and resulted in a favorable outcome. Three years after ceasing treatment, the patient presented no signs of hemolysis, but required chronic hemodialysis.. The association of TMA, especially TTP, and multiple myeloma is exceptional. The authors report such a case that induced irreversible renal damage, but with stable clinical and laboratory parameters with a follow-up of 4 years.

A 2,6,9-hetero-trisubstituted purine inhibitor exhibits potent biological effects against multiple myeloma cells.
    Bioorganic & medicinal chemistry, 2013, Sep-01, Volume: 21, Issue:17

    A focused library of hetero-trisubstituted purines was developed for improving the cell penetrating and biological efficacy of a series of anti-Stat3 protein inhibitors. From this SAR study, lead agent 22e was identified as being a promising inhibitor of MM tumour cells (IC50's <5μM). Surprisingly, biophysical and biochemical characterization proved that 22e was not a Stat3 inhibitor. Initial screening against the kinome, prompted by the purine scaffold's history for targeting ATP binding pockets, suggests possible targeting of the JAK family kinases, as well for ABL1 (nonphosphorylated F317L) and AAK1.

An inverse switch in DNA base excision and strand break repair contributes to melphalan resistance in multiple myeloma cells.
    PloS one, 2013, Volume: 8, Issue:2

    Alterations in checkpoint and DNA repair pathways may provide adaptive mechanisms contributing to acquired drug resistance. Here, we investigated the levels of proteins mediating DNA damage signaling and -repair in RPMI8226 multiple myeloma cells and its Melphalan-resistant derivative 8226-LR5. We observed markedly reduced steady-state levels of DNA glycosylases UNG2, NEIL1 and MPG in the resistant cells and cross-resistance to agents inducing their respective DNA base lesions. Conversely, repair of alkali-labile sites was apparently enhanced in the resistant cells, as substantiated by alkaline comet assay, autoribosylation of PARP-1, and increased sensitivity to PARP-1 inhibition by 4-AN or KU58684. Reduced base-excision and enhanced single-strand break repair would both contribute to the observed reduction in genomic alkali-labile sites, which could jeopardize productive processing of the more cytotoxic Melphalan-induced interstrand DNA crosslinks (ICLs). Furthermore, we found a marked upregulation of proteins in the non-homologous end-joining (NHEJ) pathway of double-strand break (DSB) repair, likely contributing to the observed increase in DSB repair kinetics in the resistant cells. Finally, we observed apparent upregulation of ATR-signaling and downregulation of ATM-signaling in the resistant cells. This was accompanied by markedly increased sensitivity towards Melphalan in the presence of ATR-, DNA-PK, or CHK1/2 inhibitors whereas no sensitizing effect was observed subsequent to ATM inhibition, suggesting that replication blocking lesions are primary triggers of the DNA damage response in the Melphalan resistant cells. In conclusion, Melphalan resistance is apparently contributed by modulation of the DNA damage response at multiple levels, including downregulation of specific repair pathways to avoid repair intermediates that could impair efficient processing of cytotoxic ICLs and ICL-induced DSBs. This study has revealed several novel candidate biomarkers for Melphalan sensitivity that will be included in targeted quantitation studies in larger patient cohorts to validate their value in prognosis as well as targets for replacement- or adjuvant therapies.

Severe gastrointestinal mucositis following high dose melphalan therapy for multiple myeloma.
    World journal of gastroenterology, 2013, Feb-07, Volume: 19, Issue:5

    Mucositis is a known complication following use of chemotherapy, but fatal mucositis is unusual and management of such cases may be challenging. Pathologically there is denudation of mucosa of gastrointestinal tract. Severe cases can develop ileus and even perforation of bowel wall. We report here a case of multiple myeloma who developed World Health Organization grade 4 gut mucositis following the use of high dose melphalan with the expulsion of "intestine-like" material.

Characterization of a novel mouse model of multiple myeloma and its use in preclinical therapeutic assessment.
    PloS one, 2013, Volume: 8, Issue:2

    To aid preclinical development of novel therapeutics for myeloma, an in vivo model which recapitulates the human condition is required. An important feature of such a model is the interaction of myeloma cells with the bone marrow microenvironment, as this interaction modulates tumour activity and protects against drug-induced apoptosis. Therefore NOD/SCIDγc(null) mice were injected intra-tibially with luciferase-tagged myeloma cells. Disease progression was monitored by weekly bioluminescent imaging (BLI) and measurement of paraprotein levels. Results were compared with magnetic resonance imaging (MRI) and histology. Assessment of model suitability for preclinical drug testing was investigated using bortezomib, melphalan and two novel agents. Cells engrafted at week 3, with a significant increase in BLI radiance occurring between weeks 5 and 7. This was accompanied by an increase in paraprotein secretion, MRI-derived tumour volume and CD138 positive cells within the bone marrow. Treatment with known anti-myeloma agents or novel agents significantly attenuated the increase in all disease markers. In addition, intra-tibial implantation of primary patient plasma cells resulted in development of myeloma within bone marrow. In conclusion, using both myeloma cell lines and primary patient cells, we have developed a model which recapitulates human myeloma by ensuring the key interaction of tumour cells with the microenvironment.

Allogeneic hematopoietic cell transplantation for consolidation of VGPR or CR for newly diagnosed multiple myeloma.
    Bone marrow transplantation, 2013, Volume: 48, Issue:9

    Allogeneic hematopoietic cell transplantation (HCT) is a potentially curative approach in patients with multiple myeloma, but its use for consolidation of first remission has not yet been fully explored. Twenty-two myeloma patients with very good partial response (VGPR) or CR received allogeneic peripheral blood grafts as consolidation from HLA-matched donors between 2007 and 2012. Conditioning regimens were fludarabine (30 mg/m(2) i.v. if with bortezomib and 40 mg/m(2) i.v. when without bortezomib, × 4 days) plus melphalan (70 mg/m(2) intravenously × 2 days) with (n=13) or without (n=9) bortezomib (1.3 mg/m(2)). The cumulative incidence of grades II - IV acute GVHD at day 100 was 45% (95% CI: 24-65%) and moderate-to-severe chronic GVHD at 2 years was 46% (95% CI: 19-69%). With a median follow-up of 18 (range, 2-61) months, the 2-year PFS estimate is 74.8% (95% CI: 45-90%), which compares favorably with the 52% (95% CI: 35-66%) after autologous HCT for similar patients (a median follow-up of 30 (range, 9-55) months). We are conducting a phase 2 study to assess the efficacy of allogeneic HCT as post-remission therapy.

Multiple myeloma treatment transformed: a population-based study of changes in initial management approaches in the United States.
    Journal of clinical oncology : official journal of the American Society of Clinical Oncology, 2013, Jun-01, Volume: 31, Issue:16

    Despite improved outcomes for multiple myeloma, little is known about changes in initial treatment at the population level for US patients. We report trends in treatment practices.. Patients (n = 1,976) with newly diagnosed myeloma in 1999, 2003, and 2007 were examined by using the National Cancer Institute's Patterns of Care Studies. We assessed use of common chemotherapies (melphalan, vincristine, and doxorubicin), novel agents (thalidomide, bortezomib, or lenalidomide), or hematopoietic stem-cell transplantation (HSCT) during the first year after diagnosis. By using logistic regression, we evaluated the association of race and insurance status with receipt of high-cost treatments--transplantation or novel agents.. From 1999 to 2007, use of melphalan alone dropped from 32.0% to 4.1%, and vincristine and doxorubicin use declined from 18.2% to 0.4%. The percentage of patients receiving any novel agent rose from 3.9% in 1999 to 75.5% in 2007. HSCT increased from 11.1% in 1999 to 21.7% in 2007. For white patients, use of novel agents was lower for those with Medicare only (42.6%) than for those with private insurance (50.2%). For patients of other races, those with Medicare only or Medicaid were less likely to receive novel agents or transplantation compared with those with private insurance.. Initial treatment for multiple myeloma has changed markedly. Most patients now receive novel agents, with a decline in the use of traditional chemotherapy. Use of transplantation and novel agents varies with race and insurance. These findings document rapid changes in patterns of care and highlight addressable disparities in myeloma care.

In vitro and in vivo antitumor activity of a novel alkylating agent, melphalan-flufenamide, against multiple myeloma cells.
    Clinical cancer research : an official journal of the American Association for Cancer Research, 2013, Jun-01, Volume: 19, Issue:11

    The alkylating agent melphalan prolongs survival in patients with multiple myeloma; however, it is associated with toxicities and development of drug-resistance. Here, we evaluated the efficacy of melphalan-flufenamide (mel-flufen), a novel dipeptide prodrug of melphalan in multiple myeloma.. Multiple myeloma cell lines, primary patient cells, and the human multiple myeloma xenograft animal model were used to study the antitumor activity of mel-flufen.. Low doses of mel-flufen trigger more rapid and higher intracellular concentrations of melphalan in multiple myeloma cells than are achievable by free melphalan. Cytotoxicity analysis showed significantly lower IC50 of mel-flufen than melphalan in multiple myeloma cells. Importantly, mel-flufen induces apoptosis even in melphalan- and bortezomib-resistant multiple myeloma cells. Mechanistic studies show that siRNA knockdown of aminopeptidase N, a key enzyme mediating intracellular conversion of mel-flufen to melphalan, attenuates anti-multiple myeloma activity of mel-flufen. Furthermore, mel-flufen-induced apoptosis was associated with: (i) activation of caspases and PARP cleavage; (ii) reactive oxygen species generation; (iii) mitochondrial dysfunction and release of cytochrome c; and (iv) induction of DNA damage. Moreover, mel-flufen inhibits multiple myeloma cell migration and tumor-associated angiogenesis. Human multiple myeloma xenograft studies showed a more potent inhibition of tumor growth in mice treated with mel-flufen than mice receiving equimolar doses of melphalan. Finally, combining mel-flufen with lenalidomide, bortezomib, or dexamethasone triggers synergistic anti-multiple myeloma activity.. Our preclinical study supports clinical evaluation of mel-flufen to enhance therapeutic potential of melphalan, overcome drug-resistance, and improve multiple myeloma patient outcome.

Role of high-dose melphalan with autologous stem cell transplantation in multiple myeloma patients receiving botezomib-containing induction therapy.
    International journal of hematology, 2013, Volume: 97, Issue:5

    To examine the role of high-dose melphalan therapy with autologous stem cell transplantation (HDM/ASCT) in the final outcomes of multiple myeloma (MM) patients receiving bortezomib-containing induction therapy (IT), we analyzed relationships between quality of response after IT including bortezomib or HDM/ASCT and survival. In total, 92 MM patients who received IT with bortezomib followed by HDM/ASCT were enrolled. The median follow-up was 28.0 months. Three-year progression-free survival (PFS) and overall survival (OS) were 41.1 and 72.0 %, respectively. A complete response (CR) after HDM/ASCT was a strong prognostic factor for PFS and OS (p = 0.002 and 0.001, respectively). Additionally, out of 67 patients who failed to achieve CR after IT, 36 (53.7 %) patients achieved CR after HDM/ASCT. PFS and OS in patients with CR after additional HDM/ASCT were similar to those in patients who had already achieved CR after IT. However, achievement of at least very good partial response following IT with bortezomib failed to improve PFS and OS (p = 0.35 and 0.11, respectively). Thus, we conclude that post-HDM/ASCT CR is the best prognostic factor for both PFS and OS regardless of response to bortezomib. Therefore, HDM/ASCT remains an important therapy in MM patients even after introduction of bortezomib IT.

Knockdown of DEPTOR inhibits cell proliferation and increases chemosensitivity to melphalan in human multiple myeloma RPMI-8226 cells via inhibiting PI3K/AKT activity.
    The Journal of international medical research, 2013, Volume: 41, Issue:3

    The present study determined the role of DEP domain containing mTOR-interacting protein (DEPTOR) in the proliferation, apoptosis and chemosensitivity of RPMI-8226 multiple myeloma cells, using small hairpin RNA (shRNA) to knock down DEPTOR gene expression in vitro.. DEPTOR mRNA and protein levels in RPMI-8226 cells treated with DEPTOR-specific shRNA were evaluated by reverse transcription-polymerase chain reaction and Western blotting. Expression of apoptosis-associated proteins (including cleaved caspase-3 and cleaved poly-ADP ribose polymerase [PARP]) and activation of the phosphatidylinositol 3-kinase (PI3K)/v-akt murine thymoma viral oncogene homologue 1 (AKT) signalling pathway were detected by Western blotting.. Transfection of DEPTOR-specific shRNA successfully knocked down DEPTOR gene expression in transfected RPMI-8226 cells. These transfected cells, together with control RPMI-8226 cells, were treated with 20 µmol/l melphalan for 24 h. Knockdown of DEPTOR exacerbated melphalan-induced growth inhibition and apoptosis, increased levels of cleaved caspase-3 and cleaved PARP, and reduced levels of phosphor-AKT.. Downregulation of DEPTOR inhibited proliferation and increased chemosensitivity to melphalan in human multiple myeloma RPMI-8226 cells via inhibiting the PI3K/AKT pathway.

The response to second-line induction with bortezomib and dexamethasone is predictive of long-term outcomes prior to high-dose chemotherapy with autologous stem cell transplantation for multiple myeloma.
    Internal medicine (Tokyo, Japan), 2013, Volume: 52, Issue:9

    We retrospectively investigated the efficacy and predictive factors for the treatment outcomes of bortezomib plus dexamethasone (BD) as second-line induction therapy prior to high-dose chemotherapy supported by autologous stem cell transplantation (HDT/ASCT) in multiple myeloma (MM) patients.. Sixty-six transplant eligible MM patients treated by the Kyoto Clinical Hematology Study Group between 2006 and 2011 were investigated. Conventional induction chemotherapy, including vincristine, doxorubicin and dexamethasone (VAD) and high-dose dexamethasone (HDD), was used as first-line induction therapy in all patients, seven (10.6%) of whom attained a very good partial response (VGPR). Of the 59 patients who did not attain VGPR with VAD or HDD, 33 were given BD as second-line induction therapy prior to HDT/ASCT.. Patients not treated with BD induction showed an overall response rate (ORR, i.e., better than partial response) of 85.3% after induction therapy, while the ORR of patients treated with BD induction improved from 42.4% after conventional induction therapy to 84.8% after BD. The overall survival (OS) and progression-free survival (PFS) of patients not treated with BD induction were not significantly influenced by the response to induction therapy. Among the patients treated with BD, failure in attaining VGPR prior to ASCT was associated with a significantly shorter PFS and it also tended to show a shorter OS, while the disease stage and achievement of a complete response after HDT/ASCT had no impact on OS or PFS.. The achievement of at least VGPR with second-line BD induction therapy is a prerequisite for attaining longer OS and PFS after HDT/ASCT.

[Busulfan, cyclophosphamide and etoposide as conditioning for autologous stem cell transplantation in multiple myeloma].
    Zhonghua xue ye xue za zhi = Zhonghua xueyexue zazhi, 2013, Volume: 34, Issue:4

    To evaluate the efficacy and safety of dose-reduced intravenous busulfan, cyclophosphamide and etoposide (BCV) as conditioning for autologous stem cell transplantation (ASCT) in multiple myeloma (MM).. From September 2007 to September 2010, thirty-two ASCT-eligible patients with MM received high dose melphalan (HDM) as conditioning in our center. Median age was 53.5 (30-63) years. From October 2010 to October 2012, thirty-eight patients conditioned by BCV regimen (intravenous busulfan, total doses 9.6 mg/kg), whose median age was 54(35-64) years.. There were no statistical differences in clinical characteristics between the two groups, including myeloma isotype, Durie-Salmon staging, international staging system(ISS), and patients received the first line, second line or more than third line therapy. The median time to neutrophil and platelet engraftment were 10.5 vs 11 days (P=0.057) and 11 vs 12 days (P=0.100) in the BCV and HDM groups, respectively. The toxicity of two conditioning regimens had no significant difference. None of hepatic veno-occlusive disease and early transplant related mortality was observed. Although overall response rates showed no significant difference between two groups (P>0.05), the CR rates increased from 44.74% pre-ASCT to 63.18% post-ASCT in the BCV group, while 37.50% to 59.38% in the HDM group. During the median follow-up of 16 months (range 2-27) in BCV group, ten patients (26.32%) developed progressive disease and PFS at 12 months were 71.37%.. In this study, the dose-reduced intravenous busulfan, cyclophosphamide and etoposide (BCV) conditioning was demonstrated an effective and safety regimen for ASCT-eligible patients with MM. However, the long term observation is needed.. 目的 评价BCV(白消安+环磷酰胺+足叶乙甙)预处理方案在多发性骨髓瘤(MM)自体造血干细胞移植(ASCT)患者的疗效和安全性。方法 2007年9月至2010年9月采用大剂量马法兰对32例MM患者行ASCT预处理(HDM组),中位年龄53.5(30~63)岁;2010年10月至2012年10月采用BCV方案(白消安静脉给药、总剂量9.6 mg/kg)对38例MM患者行ASCT预处理(BCV组),中位年龄54(35~64)岁。结果 两组患者MM分型、Durie-Salmon分期、国际分期体系(ISS)分期及接受一、二、三线以上治疗患者比例差异均无统计学意义。BCV组与HDM组比较,中性粒细胞植入时间[10.5(9~15)d对11(9~27)d,P=0.057]和血小板植入时间[11(9~210)d对12(10~45),P=0.100],差异均无统计学意义。两组患者预处理不良反应相似,无肝静脉阻塞病和移植早期死亡发生。BCV组、HDM组患者ASCT后完全缓解率(分别为63.18%、59.38%)均高于ASCT前(分别为44.74%、37.50%)。BCV组中位随访16(2~27)个月,10例(26.32%)患者出现疾病进展,1年无进展生存率为71.37%。结论 含减低剂量白消安针剂的BCV方案对于MM患者是安全、有效的ASCT预处理方案,其远期疗效尚待长期随访观察。

Therapeutic effects of lenalidomide on hemorrhagic intestinal myeloma-associated AL amyloidosis.
    Internal medicine (Tokyo, Japan), 2013, Volume: 52, Issue:10

    A 74-year-old woman with refractory IgG-κ multiple myeloma developed massive melena caused by hemorrhagic submucosal tumors in the duodenum and middle jejunum. A biopsy revealed the tumor to be marked AL amyloid deposition. Treatment with bortezomib did not improve the melena or the underlying disease. The patient also developed multiple amyloidomas in the bilateral femoral heads, which caused a fracture in the left femoral head. Treatment with lenalidomide, as the final therapeutic option, resolved the intractable melena and improved both the intestinal lesions and myeloma. This case shows that successful treatment of multiple myeloma leads to marked improvement of accompanying AL amyloidosis.

10 years of experience with thalidomide in multiple myeloma patients: report of the Czech Myeloma Group.
    Leukemia research, 2013, Volume: 37, Issue:9

    We analyzed 1156 multiple myeloma (MM) patients treated with thalidomide. The overall response rate was 63.6%, with complete remission in 13.4%. Combined regimens had better outcomes than thalidomide plus dexamethasone or single agent thalidomide. Thalidomide was not able to overcome adverse cytogenetics. Superior results were seen in patients undergoing subsequent autologous stem cell transplantation. The rate of adverse events was low. Thalidomide has a strong potential to improve response and survival measures in patients with standard risk MM. Combined regimens should be used, with lower doses of thalidomide. High risk myelomas should be treated individually.

[Multiple myeloma].
    Der Internist, 2013, Volume: 54, Issue:8

    Multiple myeloma (MM) is a cancer originating from terminally differentiated B lymphocytes, the plasma cells and is classified as a B cell non-Hodgkin lymphoma. As clonal plasma cells secrete immunoglobulin molecules (lacking antigenic specificity), an "M component" can incidentally be detected. Besides intact immunoglobulin molecules, free light chains can be produced. Although there is no specific treatment for monoclonal gammopathy of undetermined significance (MGUS), which is the defined as the presence of clonal bone marrow plasma cells and low levels (serum and/or urine) of the M component, it should be followed up in affected individuals. The symptoms of MM are numerous and often nonspecific. Diagnosis includes the quantification of monoclonal proteins in serum and urine, blood count, electrolytes and renal function, imaging of the skeleton and bone marrow puncture. The cornerstone of therapy includes melphalan- or cyclophosphamide-based regimens incorporating one of the "novel drugs" (i.e. bortezomib, thalidomide, or lenalidomide).

Inhibition of the tumour necrosis factor-alpha autocrine loop enhances the sensitivity of multiple myeloma cells to anticancer drugs.
    European journal of cancer (Oxford, England : 1990), 2013, Volume: 49, Issue:17

    Several autocrine soluble factors, including macrophage inflammatory protein-1α and tumour necrosis factor-alpha (TNF-α), promote the survival and growth of multiple myeloma (MM) cells. We hypothesised that inhibition of the TNF-α autocrine loop may enhance the cytotoxic effect of anticancer drugs in MM cell lines. In the present study, a TNF-α-neutralizing antibody suppressed cell proliferation and enhanced the cytotoxic effect of anticancer drugs on MM cells. In addition, combination treatment with the TNF-α-neutralizing antibody and the chemotherapy agent melphalan inhibited nuclear factor κB (NF-κB) p65 nuclear translocation and mammalian target of rapamycin (mTOR) activation and upregulated the expression of Bax and Bim. Treatment of ARH-77 cells with the NF-κB inhibitor dimethyl fumarate or the mTOR inhibitor rapamycin suppressed NF-κB p65 nuclear translocation and enhanced the cytotoxic effect of melphalan. Furthermore, infliximab, a monoclonal antibody against TNF-α, also enhanced the cytotoxic effect of anticancer drugs in ARH-77 cells. These results indicated that TNF-α-neutralizing antibodies or infliximab enhanced the cytotoxic effect of anticancer drugs by suppressing the TNF receptor/mTOR/NF-κB pathways. The inhibition of TNF-α may thus provide a new therapeutic approach to control tumour progression and bone destruction in MM patients.

Targeting proliferating cell nuclear antigen and its protein interactions induces apoptosis in multiple myeloma cells.
    PloS one, 2013, Volume: 8, Issue:7

    Multiple myeloma is a hematological cancer that is considered incurable despite advances in treatment strategy during the last decade. Therapies targeting single pathways are unlikely to succeed due to the heterogeneous nature of the malignancy. Proliferating cell nuclear antigen (PCNA) is a multifunctional protein essential for DNA replication and repair that is often overexpressed in cancer cells. Many proteins involved in the cellular stress response interact with PCNA through the five amino acid sequence AlkB homologue 2 PCNA-interacting motif (APIM). Thus inhibiting PCNA's protein interactions may be a good strategy to target multiple pathways simultaneously. We initially found that overexpression of peptides containing the APIM sequence increases the sensitivity of cancer cells to contemporary therapeutics. Here we have designed a cell-penetrating APIM-containing peptide, ATX-101, that targets PCNA and show that it has anti-myeloma activity. We found that ATX-101 induced apoptosis in multiple myeloma cell lines and primary cancer cells, while bone marrow stromal cells and primary healthy lymphocytes were much less sensitive. ATX-101-induced apoptosis was caspase-dependent and cell cycle phase-independent. ATX-101 also increased multiple myeloma cells' sensitivity against melphalan, a DNA damaging agent commonly used for treatment of multiple myeloma. In a xenograft mouse model, ATX-101 was well tolerated and increased the anti-tumor activity of melphalan. Therefore, targeting PCNA by ATX-101 may be a novel strategy in multiple myeloma treatment.

Using joint utilities of the times to response and toxicity to adaptively optimize schedule-dose regimes.
    Biometrics, 2013, Volume: 69, Issue:3

    A Bayesian two-stage phase I-II design is proposed for optimizing administration schedule and dose of an experimental agent based on the times to response and toxicity in the case where schedules are non-nested and qualitatively different. Sequentially adaptive decisions are based on the joint utility of the two event times. A utility function is constructed by partitioning the two-dimensional positive real quadrant of possible event time pairs into rectangles, eliciting a numerical utility for each rectangle, and fitting a smooth parametric function to the elicited values. We assume that each event time follows a gamma distribution with shape and scale parameters both modeled as functions of schedule and dose. A copula is assumed to obtain a bivariate distribution. To ensure an ethical trial, adaptive safety and efficacy acceptability conditions are imposed on the (schedule, dose) regimes. In stage 1 of the design, patients are randomized fairly among schedules and, within each schedule, a dose is chosen using a hybrid algorithm that either maximizes posterior mean utility or randomizes among acceptable doses. In stage 2, fair randomization among schedules is replaced by the hybrid algorithm. A modified version of this algorithm is used for nested schedules. Extensions of the model and utility function to accommodate death or discontinuation of follow up are described. The method is illustrated by an autologous stem cell transplantation trial in multiple myeloma, including a simulation study.

Bortezomib administered subcutaneously is well tolerated in bortezomib-based combination regimens used in patients with multiple myeloma.
    Oncology, 2013, Volume: 85, Issue:4

    Bortezomib (Btz) has emerged as a standard of care in the treatment of patients with multiple myeloma (MM), but Btz-induced peripheral neuropathy (PNP) has a particularly negative impact on patients' quality of life. According to a recent study, PNP was significantly less frequent with subcutaneous administration of Btz. Here, we report our experience regarding the efficacy and tolerability of standard combination regimens in MM with subcutaneous Btz.. 14 consecutive patients with newly diagnosed MM were included in this analysis. Btz was used in different combination regimens (Btz with dexamethasone with/without thalidomide or Btz combined with melphalan and prednisone). Standard criteria were applied to evaluate response and toxicity.. Hematological toxicities occurred only at grades 1-2 and included anemia (71%) and thrombocytopenia (21%). Nonhematologic side effects at grades 1-2 were local skin reactions at the subcutaneous injection site, which were self-limited. No notable gastrointestinal toxicity was observed with subcutaneous Btz, and therefore routine use of intravenous hydration and antiemetics was abandoned. Overall response rate for transplant-eligible patients was 86%.. Our results confirm the improved toxicity profile of the subcutaneous administration of Btz in various standard Btz-based combination regimens. In addition, patient management with subcutaneous administration has been markedly ameliorated at our center.

Total marrow irradiation as part of autologous stem cell transplantation for Asian patients with multiple myeloma.
    BioMed research international, 2013, Volume: 2013

    To compare the outcomes of melphalan 200 mg/m² (HDM200) and 8 Gy total marrow irradiation (TMI) delivered by helical tomotherapy plus melphalan 140 mg/m² (HDM140 + TMI 8 Gy) in newly diagnosed symptomatic multiple myeloma (MM) Asian patients. Between 2007 and 2010, nine consecutive myeloma patients who were scheduled to undergo autologous stem cell transplantation (ASCT) were studied. The patients received three cycles of vincristine-adriamycin-dexamethasone (VAD) regimen as induction chemotherapy, and if they had a partial response, peripheral blood stem cells were collected by dexamethasone-etoposide-cyclophosphamide-cisplatin (DECP). In arm A, six patients received the HDM200. In arm B, three patients received HDM140 + TMI 8 Gy. In arm B, the neutropenic duration was slightly longer than in arm A (P = 0.048). However, hematologic recovery (except for neutrophils), transfusion requirement, median duration of hospitalization, and the dose of G-CSF were similar in both arms. The median duration of overall survival and event-free survival was similar in the two arms (P = 0.387). As a conditioning regiment, HDM140 + TMI 8 Gy provide another chance for MM Asian patients who were not feasible for HDM200.

Long term evaluation of the impact of autologous peripheral blood stem cell transplantation in multiple myeloma: a cost-effectiveness analysis.
    PloS one, 2013, Volume: 8, Issue:9

    High-dose therapy with autologous peripheral stem cell transplantation represents today the standard approach for younger multiple myeloma patients. This study aimed to evaluate the long term economic impact of autologous transplantation with respect to conventional therapy.. We retrospectively reviewed the charts of multiple myeloma patients diagnosed at our department between 1986 and 2003 and treated according to the therapy considered standard at the time of diagnosis. Analysis of costs was done by assessing resource utilization and direct costs were measured and monetized before proceeding with the analysis, based on public health service tariffs.. Group A including 78 patients treated with Melphalan and Prednisone was compared with Group B including 74 patients who received an autologous transplant. The median overall survival was 3.2 and 5.4 years respectively (p = 0.0002). Mean cost per patient was significantly higher in group B with respect to group A (102373€ vs 23825€; p<0.001). The final quality-adjusted-life-year gain in group B patients as compared to group A was 1.73 QALY, with an incremental cost-effectiveness ratio of 45460€. With a threshold of 75000€ per QALY gained, the cost effectiveness acceptability curve indicated that the probability that autologous transplantation in multiple myeloma is a cost-effective intervention is 90%.. The cost of autologous transplantation remains high. The calculated incremental cost-effectiveness ratio, however, given the significant prolongation of overall survival obtained with autologous transplantation, is within an acceptable threshold. Notwithstanding, its high cost should be taken into account when considering the whole cost of multiple myeloma.

Genetic variants in DNA repair pathways are not associated with disease progression among multiple myeloma patients.
    Leukemia research, 2013, Volume: 37, Issue:11

    DNA damage induced by high dose melphalan and autologous transplantation is repaired by the nucleotide excision repair (NER) and base excision repair (BER) pathways. We evaluated the association between single nucleotide polymorphisms (SNPs) (n=311) in the NER and BER pathways and disease progression in 695 multiple myeloma patients who underwent autologous transplantation. None of the SNPs were associated with disease progression. Pathway based analyses showed that the NER pathway had a borderline association with disease progression (p=0.09). These findings suggest that common variation in the NER and BER pathways do not substantially influence disease progression in multiple myeloma patients.

Post-transplantation consolidation and maintenance therapy with lenalidomide for Japanese patients with multiple myeloma.
    Anticancer research, 2013, Volume: 33, Issue:12

    Post-autologous stem cell transplantation (ASCT) consolidation and maintenance therapies in multiple myeloma (MM) have recently been the central focus of studies. However, there have been no reports of Japanese patients with MM treated with post-ASCT consolidation/maintenance therapies.. We retrospectively evaluated eight Japanese patients with newly-diagnosed symptomatic MM who received ASCT after high-dose melphalan, and three to four courses of bortezomib-plus-dexamethasone and two courses of lenalidomide-plus-dexamethasone followed by maintenance lenalidomide for 6-24 months.. Four patients achieved complete response (CR) after ASCT, and five patients (63%) achieved stringent CR after the consolidation and maintenance therapy; two out of these five were in molecular CR. At the median follow-up of 38 months, all patients were alive and only one patient had disease progression following post-ASCT therapy.. Post-ASCT consolidation and maintenance therapy using lenalidomide may be effective in the treatment of Japanese patients with MM.

Proof of the concept to use a malignant B cell line drug screen strategy for identification and weight of melphalan resistance genes in multiple myeloma.
    PloS one, 2013, Volume: 8, Issue:12

    In a conceptual study of drug resistance we have used a preclinical model of malignant B-cell lines by combining drug induced growth inhibition and gene expression profiling. In the current report a melphalan resistance profile of 19 genes were weighted by microarray data from the MRC Myeloma IX trial and time to progression following high dose melphalan, to generate an individual melphalan resistance index. The resistance index was subsequently validated in the HOVON65/GMMG-HD4 trial data set to prove the concept. Biologically, the assigned resistance indices were differentially distributed among translocations and cyclin D expression classes. Clinically, the 25% most melphalan resistant, the intermediate 50% and the 25% most sensitive patients had a median progression free survival of 18, 32 and 28 months, respectively (log-rank P-value  = 0.05). Furthermore, the median overall survival was 45 months for the resistant group and not reached for the intermediate and sensitive groups (log-rank P-value  = 0.003) following 38 months median observation. In a multivariate analysis, correcting for age, sex and ISS-staging, we found a high resistance index to be an independent variable associated with inferior progression free survival and overall survival. This study provides clinical proof of concept to use in vitro drug screen for identification of melphalan resistance gene signatures for future functional analysis.

Additional genetic abnormalities significantly worsen poor prognosis associated with 1q21 amplification in multiple myeloma patients.
    Hematological oncology, 2013, Volume: 31, Issue:1

    We investigated the prognostic value of amp(1q21) alone and in combination with other abnormalities in newly diagnosed myeloma patients. The study group consisted of 104 patients treated with various induction regimens, mostly thalidomide based (87 patients). Amp(1q21) was detected in 49 (47.1%) of patients; in 26 (25.0%) cases, it was combined with del(13q14), in 7 (6.7%) with del(17p13) and in 15 (14.4%) with t(4;14)(p16;q32). The response rate was significantly better in amp(1q21)-negative than in amp(1q21)-positive patients (74.5% vs 55.1%, p = 0.025; complete response 18.2% vs 4.1%, p = 0.024). The median progression-free survival (PFS) was 33.9 months in patients without amp(1q21) and 10.3 months with this aberration (p = 0.002). The presence of additional abnormalities resulted in significantly shortened PFS when compared with patients with isolated amp(1q21): coexisting del(13q14) resulted in 7.8 vs 29.0 months of PFS (p = 0.024) and del(17p13) resulted in 4.0 vs 24.9 months of PFS (p = 0.034). The presence of amp(1q21) significantly influenced overall survival (OS) as well as PFS resulting in the median OS of 26.6 vs 62.4 months (p = 0.018) in patients without amp(1q21). The presence of additional genetic abnormalities significantly affected OS when compared with patients carrying isolated amp(1q21): for del(13q14) 18.9 vs 58.4 months (p = 0.004) and for del(17p13) 12.0 vs 46.5 months (p = 0.036). On multivariate analysis amp(1q21), del(13q14) and del(17p13) were found to be an independent adverse predictors of shorter PFS and OS. Our results showed that the presence of amp(1q21) was associated with poor prognosis. Moreover additional genetic abnormalities made PFS and OS further shortened.

The role of novel agents on the reversibility of renal impairment in newly diagnosed symptomatic patients with multiple myeloma.
    Leukemia, 2013, Volume: 27, Issue:2

    The role of thalidomide, bortezomib and lenalidomide in multiple myeloma patients presenting with renal impairment was evaluated in 133 consecutive newly diagnosed patients who were treated with a novel agent-based regimen. A significant improvement of renal function (renalPR (renal partial response)) was observed in 77% of patients treated with bortezomib, in 55% with thalidomide and in 43% with lenalidomide (P=0.011). In multivariate analysis, bortezomib-based therapy was independently associated with a higher probability of renal response compared with thalidomide- or lenalidomide-based therapy. Other important variables included eGFR (estimated glomerular filtration rate) ≥30 ml/min, age ≤65 years and myeloma response. Patients treated with bortezomib achieved at least renalPR in a median of 1.34 months vs 2.7 months for thalidomide and >6 months for lenalidomide-treated patients (P=0.028). In multivariate analysis bortezomib-based therapy, higher doses of dexamethasone (≥160 mg during the first month of treatment), an eGFR ≥30 ml/min and age ≤65 years were independently associated with shorter time to renal response. In conclusion, bortezomib-based therapies may be more appropriate for the initial management of patients with myeloma-related renal failure; however, thalidomide and lenalidomide are also associated with significant probability of improvement of their renal function.

PSGL-1/selectin and ICAM-1/CD18 interactions are involved in macrophage-induced drug resistance in myeloma.
    Leukemia, 2013, Volume: 27, Issue:3

    Chemoresistance is the major obstacle in multiple myeloma (MM) management. We previously showed that macrophages protect myeloma cells, on a cell contact basis, from melphalan or dexamethasone-induced apoptosis in vitro. In this study, we found that macrophage-mediated myeloma drug resistance was also seen with purified macrophages from myeloma patients' bone marrow (BM) in vitro and was confirmed in vivo using the human myeloma-SCID (severe combined immunodeficient) mouse model. By profiling differentially regulated and paired plasma membrane protein genes, we showed that PSGL-1 (P-selectin glycoprotein ligand-1)/selectins and ICAM-1/CD18 played an important role in macrophage-mediated myeloma cell drug resistance, as blocking antibodies against these molecules or genetic knockdown of PSGL-1 or ICAM-1 in myeloma cells repressed macrophages' ability to protect myeloma cells. Interaction of macrophages and myeloma cells via these molecules activated Src and Erk1/2 kinases and c-myc pathways and suppressed caspase activation induced by chemotherapy drugs. Thus, our study sheds new light on the mechanism of drug resistance in MM and provides novel targets for improving the efficacy of chemotherapy in patients.

Impact of high-risk cytogenetics and achievement of molecular remission on long-term freedom from disease after autologous-allogeneic tandem transplantation in patients with multiple myeloma.
    Biology of blood and marrow transplantation : journal of the American Society for Blood and Marrow Transplantation, 2013, Volume: 19, Issue:3

    Within a prospective protocol, the incidence and impact of achievement of molecular remission (mCR) and high-risk cytogenetics was investigated in 73 patients with multiple myeloma (MM) after autologous (auto)-allogeneic (allo) tandem stem cell transplantation (SCT). After induction chemotherapy, patients received melphalan 200 mg/m(2) before undergoing auto-SCT, followed 3 months later by melphalan 140 mg/m(2) and fludarabine 180 mg/m(2) before allo-SCT. Sixteen patients had high-risk cytogenetic features, defined by positive FISH for del(17p13) and/or t(4;14). Overall, 66% of the patients achieved CR or near-CR, and 41% achieved mCR, which was sustained negative (at least 4 consecutive samples negative) in 15 patients (21%), with no significant difference in incidence between the patients with high-risk cytogenetics and others (P = .70). After a median follow-up of 6 years, overall 5-year progression-free survival was 29%, with no significant difference between del 17p13/t(4;14)-harboring patients and others (24% versus 30%; P = .70). The 5-year progression-free survival differed substantially according to the achieved remission: 17% for partial remission, 41% for CR, 57% for mCR, and 85% for sustained mCR. These results suggest that auto-allo tandem SCT may overcome the negative prognostic effect of del(17p13) and/or t(4;14) and that achievement of molecular remission resulted in long-term freedom from disease.

Autologous stem cell transplantation for multiple myeloma: identification of prognostic factors.
    Clinical lymphoma, myeloma & leukemia, 2013, Volume: 13, Issue:1

    The purpose of this study was to evaluate the effect of prognostic factors on the outcome of patients with MM after ASCT.. We analyzed results of 170 consecutive patients (121 male and 49 female) of MM who underwent ASCT. Patients' median age was 52 years (range, 26-68 years). High dose melphalan (200 mg/m(2)) was used for conditioning. One hundred thirty-two patients (77.6%) had evidence of chemosensitive disease before transplant. Response was assessed using European Group for Blood and Bone Marrow Transplantation criteria.. Post ASCT 44.7% of patients achieved CR, 24.7% had very good partial response (VGPR), and 21.2% had partial response (PR). Presence of pretransplant chemosensitive disease (CR, VGPR, and PR) and transplant within 12 months of diagnosis for years before 2006 were associated with higher response rates on multivariate analysis. At a median follow-up of 84 months, median overall (OS) and event-free survival (EFS) is 85.5 and 41 months, respectively. Estimated OS and EFS at 60 months is 62 ± 0.04% and 41 ± 0.04%, respectively. Patients who responded to transplant (CR, VGPR, and PR) had a longer OS (P < .001) and EFS (P < .001). Additionally, patients who achieved CR post transplant had a longer OS (P < .001) and EFS (P < .001). Patients who received novel agents for induction pretransplant had a longer OS (P < .001) and EFS (P < .002).. Outcome after ASCT is better for myeloma patients with pretransplant chemosensitive disease and those who achieve CR after transplant.

Bortezomib with high dose melphalan conditioning for autologous transplant is safe and effective in patients with heavily pretreated and high risk multiple myeloma.
    Leukemia & lymphoma, 2013, Volume: 54, Issue:7

    There are no uniform guidelines for the treatment of relapsed refractory multiple myeloma (MM), however autologous stem cell transplant (SCT) remains an important treatment modality. Although a number of modifications to high dose melphalan (HDM) conditioning have been evaluated, improvement in overall survival has not been demonstrated. We now report our experience of 23 patients with heavily pretreated MM (median lines of prior treatment 3 [range 1-6]) who underwent SCT with bortezomib and high dose melphalan (BorHDM). The overall response rate (at least partial response [PR]) was 65.4%. Median overall survival (OS) was 24 months. A subset of patients who relapsed ≤ 12 months after initial SCT had significantly longer OS after BorHDM SCT compared to a historical control group who received HDM conditioning alone (14.5 vs. 8 months, respectively, p = 0.011). In summary, BorHDM SCT produces very good response rates in heavily pretreated MM, and may increase survival in the salvage setting in patients who relapse early after initial SCT. We propose that its use should be explored as part of a tandem approach in patients undergoing initial SCT who are at high risk of early relapse.

Intravenous injection of bortezomib, melphalan and dexamethasone in refractory and relapsed multiple myeloma.
    Annals of oncology : official journal of the European Society for Medical Oncology, 2013, Volume: 24, Issue:4

    A combination of bortezomib (1.3 mg/m(2)), melphalan (5 mg/m(2)), and dexamethasone (40 mg) (BMD), with all three drugs given as a contemporary intravenous administration, was retrospectively evaluated.. Fifty previously treated (median 2 previous lines) patients with myeloma (33 relapsed and 17 refractory) were assessed. The first 19 patients were treated with a twice-a-week (days 1, 4, 8, 11, 'base' schedule) administration while, in the remaining 31 patients, the three drugs were administered once a week (days 1, 8, 15, 22, 'weekly' schedule).. Side-effects were predictable and manageable, with prominent haematological toxicity, and a better toxic profile in 'weekly' schedule (36% versus 66% in 'base' schedule). The overall response rate was 62%. After median follow-up of 24.5 months (range 2.7-50 months), the median progression-free survival (PFS) was 21.6 with no difference between the two schedules and the median overall survival (OS) was 33.8 months. Independently from the adopted schedule, we found that also in a cohort of relapsed/refractory patients achieving at least partial remission improved PFS (35.2 versus 9 months) and OS (unreached median versus 18 months).. Taken together, our observations suggest that BMD is an effective regimen in advanced myeloma patients with acceptable toxicity.

Late relapses following reduced intensity allogeneic transplantation in patients with multiple myeloma: a long-term follow-up study.
    British journal of haematology, 2013, Volume: 160, Issue:2

    We analysed the long-term outcomes of 60 multiple myeloma patients who underwent reduced intensity allogeneic stem cell transplantation between August 2000 and March 2008. Regimens included fludarabine and melphalan conditioning (flu-mel regimen) for allogeneic haematopoietic cell transplant (HCT) or a planned tandem regimen consisting of high-dose melphalan conditioning for autograft followed by low-dose total body irradiation conditioning for allogeneic HCT (auto-allo regimen). Donors included human-leucocyte-antigen-matched siblings (n = 55) or matched unrelated donors (n = 5). With a median follow-up of 9·8 years, 7-year overall survival (OS) and progression-free survival (PFS) were 60% and 31%, respectively. By multivariate Cox regression analysis, disease status of complete response (CR) or partial response (PR) at transplant and the presence of chronic graft-versus-host disease were significantly associated with improved OS. Only disease status was significantly associated with improved PFS. We noted a surprising number of very late relapses, with six patients (10%) relapsing between 6 and 12 years post-transplant. Among the six late relapse patients, all were transplanted within 14 months of diagnosis, five had normal karyotypes, and five were in CR/PR. Our data provide additional evidence that, while survival may be extended by reduced intensity allogeneic transplant, ultimately, it may not offer a cure.

The cost-effectiveness of initial treatment of multiple myeloma in the U.S. with bortezomib plus melphalan and prednisone versus thalidomide plus melphalan and prednisone or lenalidomide plus melphalan and prednisone with continuous lenalidomide maintenan
    The oncologist, 2013, Volume: 18, Issue:1

    The outlook for transplant-ineligible multiple myeloma patients has improved enormously over recent years with the incorporation of new agents into standard regimens. Novel regimens combine melphalan and prednisone (MP) with bortezomib (VMP), with thalidomide (MPT), and with lenalidomide with (MPR-R) and without (MPR) lenalidomide maintenance. The efficacy, safety, and cost-effectiveness of these regimens have not yet been compared; therefore, we conducted a pharmacoeconomic analysis using data from randomized controlled trials versus MP. Using a Markov model developed from a U.S. payer's perspective, we compared VMP with MPT and MPR-R over a lifetime horizon. MPT and MPR-R were chosen because, like VMP, they are superior to MP in response and outcomes. Data from the Velcade as Initial Standard Therapy in Multiple Myeloma (VISTA; VMP), Intergroupe Francophone du Myelome (IFM) 99-06 (MPT), and MM-015 (MPR-R) trials were used. The IFM 99-06 study was selected because of the superior activity in this study compared with other MPT studies. Using patient-level (VMP) and published (MPT, MPR-R) data, we estimated the health-state transition and adverse event probabilities for each regimen, related costs, and state-specific utility estimates. Costs (in 2010 U.S. dollars) and health outcomes were discounted at 3%. Discounted lifetime direct medical costs were lowest with VMP at $119,102. MPT cost $142,452 whereas MPR-R cost $248,358. Incremental cost-effectiveness ratio calculations projected that VMP would confer cost savings and better health outcomes relative to MPT and MPR-R. We conclude that VMP is highly likely to be cost-effective compared with MP, MPT, and MPR-R.

Feasibility of autologous hematopoietic stem cell transplant in patients aged ≥70 years with multiple myeloma.
    Leukemia & lymphoma, 2012, Volume: 53, Issue:1

    Abstract We retrospectively analyzed the outcomes of all consecutive patients with myeloma (n = 84) aged ≥70 years who had received autologous hematopoietic stem cell transplant (auto HCT) between July 1999 and June 2010 at our institution. The median age at auto HCT was 72 years, the median number of prior therapies was 2.5 and the median time from diagnosis to auto HCT was 10.2 months. The conditioning regimen consisted of melphalan at 140 mg/m(2) in 10%, 180 mg/m(2) in 25% and 200 mg/m(2) in 65% of patients. The day-100 non-relapse mortality was 3%. The overall response rate at day 100 was 85% (complete response 18%, very good partial response 12%, partial response 55%). After a median follow-up of 25 months among surviving patients, the estimated progression-free survival and overall survival at 5 years were 27% and 67%, respectively. The incidence of grade II-IV toxicity, response rate and survival were similar across three melphalan dose levels. These results indicate that high-dose melphalan plus auto HCT is safe and feasible for patients with multiple myeloma aged ≥70 years and age alone should not be an exclusion criterion for auto HCT.

Anaplastic atypical myeloma with extensive cutaneous involvement in a dog.
    The Journal of veterinary medical science, 2012, Volume: 74, Issue:1

    A 7-year-old, male, mixed breed dog was referred to the Veterinary Teaching Hospital at Kitasato University because of anorexia, lameness and multiple cutaneous lesions. Observation of bone marrow plasmacytosis, osteolytic bone lesions, serum myeloma protein and cutaneous infiltration of myeloma cells led us to a diagnosis of multiple myeloma (MM) with cutaneous involvement. Polymerase chain reaction and sequence analysis for the rearranged genes of immunoglobulin and T-cell receptor demonstrated that the neoplastic cells found in skin lesions or bone marrow are of B-lymphocyte lineage and share a common original precursor cell. The dog was treated with UW-Madison protocol or melphalan/prednisone protocol and survived 175 days. This is rare case of anaplastic MM with cutaneous involvement in dog.

Second autologous stem cell transplantation as salvage therapy for multiple myeloma: impact on progression-free and overall survival.
    Biology of blood and marrow transplantation : journal of the American Society for Blood and Marrow Transplantation, 2012, Volume: 18, Issue:5

    The role of a second autologous stem cell transplant (ASCT) as salvage therapy is unclear, particularly with the availability of novel agents to treat progressive multiple myeloma (MM). We retrospectively reviewed all MM patients who received a second ASCT as salvage therapy at our center from March 1992 to December 2009. Eighty-one MM patients received a second ASCT for relapsed MM. The median time to relapse after first transplant was 39 months (9.83-100). All patients received reinduction therapy before the second ASCT. The high-dose regimen given before the second ASCT consisted of melphalan (MEL) alone in the majority. Complete response, very good partial response, and partial response were seen in 7.7%, 39.7%, and 50%, respectively, at day 100 post-ASCT; the median time to relapse after the second ASCT was 19 months. Early deaths occurred in 2.6%. Median progression-free survival (PFS) based on the time to myeloma relapse after first ASCT was 9.83 months (relapse ≤ 24 months) and 17.3 months (relapse ≥ 24 months) (P < .05). Median overall survival (OS) was 28.47 months (relapse ≤ 24 months) and 71.3 months (relapse >24 months) (P = .006). Second ASCT is a feasible and safe option for salvage therapy in MM. The best outcome was observed in patients whose time to progression was >24 months after first ASCT, as these patients had a subsequent PFS lasting over 1 year and an OS of almost 6 years.

Cyclophosphamide-containing regimen (TCD) is superior to melphalan-containing regimen (MPT) in elderly multiple myeloma patients with renal impairment.
    Annals of hematology, 2012, Volume: 91, Issue:6

    Renal impairment (RI) is a frequent complication with higher incidence of infections and an important prognostic factor for survival. Melphalan clearance is renal function dependent whereas cyclophosphamide is renal function independent. We investigated which combination regimen should be selected between melphalan-combining regimen (MPT) or cyclophosphamide-combining regimen (TCD) in elderly multiple myeloma (MM) patients with RI. Between 2005 and 2009, 157 newly diagnosed MM patients with RI were included comparing MPT with TCD therapy as initial treatment. Seventy-four patients were given MPT regimen, and 83 patients were given TCD regimen. Baseline characteristics were similar between the MPT and TCD groups. Analysis of different cutoff levels between 25% and 75% quartiles using log-rank test determined that glomerular filtration rate (GFR), 40 ml/min/1.73 m(2) as the cutoff point, yielded the highest difference in event-free survival (EFS) and overall survival (OS). The MPT subgroup with low GFR (GFR <40 ml/min/1.73 m(2)) had poorer response rates than others. The incidence of neutropenia and infection with febrile neutropenia were higher in the MPT subgroup with low GFR than the others (p = 0.016, p < 0.001). Furthermore, mortality due to the infection was higher in the MPT subgroup with low GFR than the others (p < 0.001). EFS was lower in the MPT subgroup with low GFR than the others (p < 0.001). OS was lower in the MPT subgroup with low GFR than the others (p < 0.001). In newly diagnosed elderly MM patients with RI, TCD regimen would be an effective and tolerable treatment option due to the combination of cyclophosphamide independent to renal function and dexamethasone effective for RI.

Bioactivity and prognostic significance of growth differentiation factor GDF15 secreted by bone marrow mesenchymal stem cells in multiple myeloma.
    Cancer research, 2012, Mar-15, Volume: 72, Issue:6

    Overexpression of growth differentiation factor 15 (GDF15) by bone marrow mesenchymal stem cells occurs widely in patients with multiple myeloma, but the pathophysiologic effects of GDF15 in this setting remain undefined. GDF15 has been described in numerous solid tumors but never in hematologic malignancies. In this study, we report that GDF15 significantly increases survival of stroma-dependent multiple myeloma cells including primary multiple myeloma cells. In particular, GDF15 conferred resistance to melphalan, bortezomib, and to a lesser extent, lenalidomide in both stroma-dependent and stroma-independent multiple myeloma cells. Akt-dependent signaling was critical to mediate the effects of GDF15, whereas Src and extracellular signal-regulated kinase 1/2 signaling pathways were not involved. Given these results, we tested the clinical significance of plasma concentrations of GDF15 (pGDF15) in 131 patients with multiple myeloma and found that it correlated with disease prognosis. Specifically, patients with high levels of pGDF15 had lower probabilities of event-free and overall survival 30 months after diagnosis than patients with low pGDF15 levels. Our findings suggest that tumor microenvironment-derived GDF15 is a key survival and chemoprotective factor for multiple myeloma cells, which is pathophysiologically linked to both initial parameters of the disease as well as patient survival.

The novel, orally bioavailable HSP90 inhibitor NVP-HSP990 induces cell cycle arrest and apoptosis in multiple myeloma cells and acts synergistically with melphalan by increased cleavage of caspases.
    European journal of haematology, 2012, Volume: 88, Issue:5

    Heat shock protein 90 (HSP90) binds and stabilizes numerous proteins and kinases essential for myeloma cell survival and proliferation. We and others have recently demonstrated that inhibition of HSP90 by small molecular mass inhibitors induces cell death in multiple myeloma (MM). However, some of the HSP90 inhibitors involved in early clinical trials have shown limited antitumor activity and unfavorable toxicity profiles. Here, we analyzed the effects of the novel, orally bioavailable HSP90 inhibitor NVP-HSP990 on MM cell proliferation and survival. The inhibitor led to a significant reduction in myeloma cell viability and induced G2 cell cycle arrest, degradation of caspase-8 and caspase-3, and induction of apoptosis. Inhibition of the HSP90 ATPase activity was accompanied by the degradation of MM phospho-Akt and phospho-ERK1/2 and upregulation of Hsp70. Exposure of MM cells to a combination of NVP-HSP990 and either melphalan or histone deacetylase (HDAC) inhibitors caused synergistic inhibition of viability, increased induction of apoptosis, and was able to overcome the primary resistance of the cell line RPMI-8226 to HSP90 inhibition. Combined incubation with melphalan and NVP-HSP990 led to synergistically increased cleavage of caspase-2, caspase-9, and caspase-3. These data demonstrate promising activity for NVP-HSP990 as single agent or combination treatment in MM and provide a rationale for clinical trials.

Melphalan plus prednisolone in the treatment of multiple myeloma.
    Mymensingh medical journal : MMJ, 2012, Volume: 21, Issue:1

    Various chemotherapies are used for better remission of symptoms of multiple myeloma as it is not a curable disease. This study was carried out to evaluate the response of melphalan plus prednisolone therapy for the treatment of Multiple myeloma. The study was conducted in the outpatient department of Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka from January to December 2009. A total of 21 patients were included in this study. Combinations of melphalan plus prednisolone were given. Data were analyzed by paired 't' test to evaluate the response after treatment. Most of the patients were within 40-60 years with a male predominance. Haemoglobin level significantly raised after therapy (p<0.001) and ESR was found significantly reduced of these patients after treatment (p<0.001). On the other hand no significant change seen in calcium level before & after therapy (p=0.713). Significantly raised albumin and B2 microglubulin level were also found after treatment (p<0.001). After therapy with malphalan plus prednisolone, 11(52.38%) patient's M Protein reduction was >75%, 7(33.33%) patients M Protein reduction was 50-75%, 1(9.5%) patient's M Protein reduction was >25-50% and 1(12.50%) patient's M Protein reduction was <25%. Mean±SD M protein values before & after therapy were 50.23±19.49 gm/l and 21.01±16.11 gm/1 respectively. M protein level significantly reduced after treatment (p<0.001).

Response of vincristine, melphalan, cyclophosphamide and prednisolone in refractory multiple myeloma.
    Mymensingh medical journal : MMJ, 2012, Volume: 21, Issue:1

    In refractory and relapsing multiple, myeloma good complete response rates may be achieved by Vincristine, Melphalan, Cyclophosphamide and Prednisolone (VMCP) like regimen which is effective alternative and less expensive in developing country like Bangladesh. The study was conducted to see the response of VMCP as an alternative in relapsing or refractory multiple myeloma. The study has been carried out in the department of Haematology, Bangabandhu Sheikh Mujib Medical University from July 2004 to June, 2005. This study was conducted on refractory case of multiple myeloma, having aged between 45 to 70 years. A total of ten patients had been taken for this study group. Newly diagnosed multiple myeloma is not included in this study. All of the 10 patients were treated according to the following VMCP protocol, Vincristine 1mg IV, d1, Melphalan 6mg/m2/d p.o. d1-d7, Cyclophosphamide 120mg/m2/d p.o. d1-d7 Prednisolone 60mg/m2/d p.o. d1-d7. Cycles were repeated every 28 days for 6 cycle. Six out of ten patients with refractory multiple myeloma displayed minimal response (60%) after treatment with 6 cycle of VMCP protocol, three patients entered partial remission (30%), and one (10%) showed complete response.

Ciprofloxacin prophylaxis for patients undergoing high-dose chemotherapy and autologous stem cell transplantation (ASCT) - a single-center experience.
    Advances in medical sciences, 2012, Jun-01, Volume: 57, Issue:1

    The objective of the study was to evaluate the efficacy of ciprofloxacin prophylaxis for patients undergoing high-dose chemotherapy followed by autologous stem cell transplantation (ASCT).. The data of 104 patients transplanted at the Department of Hematology Medical University of Lodz between 2005 and 2008 were analyzed. The cohort was divided into two groups depending on the administered ciprofloxacin prophylaxis. Conditioning regimens did not differ significantly among the groups. Multiple myeloma was the main indication for ASCT in both groups.. Ciprofloxacin prophylaxis resulted in a statistically significant reduction of duration of intravenous (IV) antibiotic treatment in the group with prophylaxis (p=0.01). The trend has been observed towards lower prevalence of infectious episodes in the prophylaxis group. Positive blood cultures were similar in both groups with no significant resistance to ciprofloxacin.. These data demonstrate that ciprofloxacin prophylaxis is beneficial for patients treated with ASCT following high dose chemotherapy regimen, in terms of the intravenous antibiotics usage. This advantage directly translates into economic benefit and may also induce less bacterial resistance due to less exposure to antibiotics.

Differential gene expression analysis related to extracellular matrix components in drug-resistant RPMI-8226 cell line.
    Biomedicine & pharmacotherapy = Biomedecine & pharmacotherapie, 2012, Volume: 66, Issue:3

    Drug resistance remains a major obstacle to the successful use of chemotherapeutic drugs for many types of cancers including multiple myeloma. It is becoming increasingly apparent that tumor microenvironment could provide a shelter to malignant plasma cells that allow their survival after initial drug exposure. This study demonstrates alterations in gene expression levels of several extracellular matrix (ECM) components in prednisone, vincristine and melphalan-resistant RPMI-8226 myeloma cells. Resistant RPMI-8226 cells were developed through stepwise selection of cells by increasing concentrations of drugs. Microarray analysis was carried out and genes up- or downregulated more than two-folds were considered as significant. Different types of ECM components were altered in different drug resistant RPMI-8226 sublines. ITGAL and ITGB2 were both overexpressed in vincristine resistant cell line whereas they were both downregulated in prednisone resistant subline. On the other hand, LAMC1 gene was drastically overexpressed in prednisone resistant subline whereas it was downregulated in its melphalan resistant variant. FN1 gene was only upregulated in vincristine resistant cells. However, COL21A1 which is an ECM component of the blood vessel walls, was drastically downregulated in all of the drug resistant RPMI-8226 sublines. ADAM17 gene was upregulated in melphalan resistant subline. This report provides a preliminary in vitro study to the relationship between drug resistance and ECM components in multiple myeloma. Since in vitro developed drug-resistant multiple myeloma sublines do not have similar microenvironment of tumor cells, correlation of ECM proteins with drug resistance requires further analysis.

Evidence that aberrant protein metabolism contributes to chemoresistance in multiple myeloma cells.
    Oncology reports, 2012, Volume: 27, Issue:6

    Multiple myeloma (MM) is an incurable B lymphocyte cancer. To date, a comparative analysis of global protein metabolism for the MM cell line CCL-155 (RPMI-8226) and the non-cancerous B lymphocyte cell line CCL-156 (RPMI‑1788) has not been published. Here, we report that both global protein synthesis and degradation occur at a higher rate in MM cells and demonstrate that alkylating agents can reduce global protein degradation in both cell lines, but the effect is greater in CCL-156 cells. Treatment with melphalan plus the proteasome inhibitor MG132 reduced global protein degradation for MM cells to roughly 60% of that seen without drugs, but the reduction was approximately three times greater for CCL-156 cells. This drug combination was growth inhibitory for both cell lines, but CCL-156 inhibition was 2-fold greater than that of the MM cell line. Additionally, treatment with melphalan plus the lysosomal inhibitor chloroquine did not affect growth of MM cells more than melphalan alone, whereas this combination drastically inhibited growth of CCL-156 cells despite protein degradation being maintained at 60% level for both cell lines. This suggests that a lysosomal function other than protein degradation is required for recovery from alkylation damage in CCL-156 cells. In general, CCL-156 cells were affected to a greater extent for both protein degradation and growth inhibition with most drug combinations tested. Statistical analysis of our data (p=0.066) provides evidence that aberrant proteasome-mediated protein degradation correlates with chemoresistance in MM cells, but that lysosome-mediated protein degradation does not.

Prognostic significance of serum cystatin C in multiple myeloma.
    International journal of hematology, 2012, Volume: 95, Issue:5

    Multiple myeloma (MM) is frequently complicated by renal insufficiency, which is associated with an unfavorable prognosis. Serum cystatin C is a new and accurate marker of glomerular filtration rate. Global gene expression analysis has revealed serum cystatin C as one of the most highly upregulated genes in MM. Recent data have shown serum cystatin C as an independent prognostic marker in MM. To further elucidate the prognostic significance of serum cystatin C, we investigated pretreatment serum cystatin C levels in 68 newly diagnosed patients homogeneously treated with high-dose melphalan followed by autologous stem cell transplantation. Median serum cystatin C level in MM patients was significantly higher than in the 66 healthy controls (1.07 vs. 0.74 mg/L [p = 0.002]). Median serum cystatin C levels significantly increased with higher International Staging System (ISS) stages (stage I 0.72 mg/L; stage II 0.89 mg/L; stage III 1.28 mg/L; p < 0.0001). Higher serum cystatin C was positively correlated with higher serum levels of creatinine (r = 0.84; p < 0.0001), β2-microglobulin (r = 0.72; p < 0.0001), LDH (r = 0.43; p = 0.0003), white blood cell counts (r = 0.61; p < 0.0001) and calcium (r = 0.29; p = 0.016), and negatively correlated with lower serum albumin levels (r = 0.44; p < 0.0001) and hemoglobin levels (r = 0.31; p = 0.01). Using ROC analysis, patients with serum cystatin C levels ≥0.95 mg/L (n = 24) had a significantly shorter event-free survival (EFS) and overall survival (OS) than patients with serum cystatin C levels <0.95 mg/L (median EFS: 26 vs. 44 months, p < 0.0001; median OS: 54 vs. 68 months, p = 0.05). Moreover, the combination of serum cystatin C level and genomic aberrations further refined the prognostic information (EFS and OS) provided by either one of the factors. The level of serum cystatin C is not only a sensitive marker of renal function, but also reflects tumor burden and delivers prognostic information in MM.

Development and validation of a PCR-based assay for the selection of patients more likely to benefit from therapeutic treatment with alkylating drugs.
    British journal of clinical pharmacology, 2012, Volume: 74, Issue:5

    Previous studies have indicated that the levels of DNA damage induced in peripheral blood mononuclear cells by the alkylating drugs melphalan, cisplatin and carboplatin can serve as useful biomarkers predictive of the therapeutic response of cancer patients to these drugs.. In the present study we developed a quantitative PCR-based assay, for the measurement of DNA damage. The advantages of this methodology are based on: its far greater sensitivity (about 250 times) than the traditional Southern blot-based method (the detection limit is ~10-20 lesions/10(6) nucleotides from the equivalent DNA of ~8000 cells); its simplicity and speed (results obtained within ~8h); its excellent reproducibility, with a coefficient of variance of 10-15% for different DNA preparations from similarly treated cells; its requirement for only minute amounts of material, and; the avoidance of radioisotope labeling. Moreover, emphasis was given to translate basic research findings into clinical practice through the validation of this assay for prediction of clinical outcome in multiple myeloma patients.. In order to develop and validate a simple, sensitive and rapid method for the quantitation of alkylating drug-induced DNA damage.. HepG2 cells and blood samples were treated with alkylating drugs (melphalan, cisplatin, carboplatin). Gene-specific damage was examined using Southern blot and a multiplex long quantitative PCR (QPCR) carried out in a 7 kb fragment (part of the p53 gene) and a 0.5 kb fragment (part of the IFN-β1 sequence; internal standard).. The extent of PCR amplification of a p53 fragment was inversely proportional to the treatment concentrations of all anticancer drugs examined, indicating a dose-related inhibition by the DNA adducts formed. Parallel analysis of the same samples using both Southern blot and QPCR showed that the DNA adducts measured by QPCR corresponded to the interstrand cross-links in the case of melphalan, and to total drug-induced lesions in the case of the platinum drugs. The detection limit was ~10-20 lesions/10(6) nucleotides using DNA from ~8000 cells. The method is about 250 times more sensitive than the Southern blot-based method and the reproducibility is excellent, with an intraday coefficient of variance (CV) of 5-9% and an interday CV of 4-12%. Application of the QPCR assay to ex vivo melphalan-treated peripheral blood mononuclear cells from multiple myeloma patients, showed that the positive predictive value of this assay for clinical response to melphalan therapy was 92.9%.. The PCR-based assay developed in this study can be used for the selection of cancer patients more likely to benefit from therapeutic treatment with alkylating drugs.

Multiple myeloma: treatment evolution.
    Hematology (Amsterdam, Netherlands), 2012, Volume: 17 Suppl 1

    Melphalan-prednisone (MP) was introduced for the treatment of MM in late 1960s. In the subsequent 30 years, the treatment improvements remained stagnant, since more complex chemotherapy combinations, such as vincristine, doxorubicin, and dexamethasone (VAD), or with the addition of BCNU (VBAD) or melphalan and cyclophosphamide (VCMP), only led to small increases in the overall response rate but without differences in survival, as assessed in a large meta-analysis that included over 6000 patients. The next step forward was the use of high-dose melphalan followed by stem cell support (autologous stem cell transplant - ASCT) for young myeloma patients, which resulted in a significant improvement in disease free survival and overall survival. However, for elderly patients MP remained as the standard of care. From year 2000, a revolution in the treatment armamentarium of MM has emerged with the availability of new agents with singular mechanism of action such as thalidomide and lenalidomide (Revlimid®), both immunomodulatory drugs and the proteasome inhibitor bortezomib (Velcade®).

Cytomegalovirus reactivation following autologous peripheral blood stem cell transplantation for multiple myeloma in the era of novel chemotherapeutics and tandem transplantation.
    Biology of blood and marrow transplantation : journal of the American Society for Blood and Marrow Transplantation, 2012, Volume: 18, Issue:11

    Cytomegalovirus (CMV) is an important pathogen after allogeneic transplantation. However, few studies have examined CMV reactivation after autologous peripheral blood stem cell transplantation (APBSCT) to treat multiple myeloma (MM), especially in the setting of the newer chemotherapeutic agents and/or 2 sequential APBSCTs (ie, tandem transplantation). A retrospective chart review of patients with MM who underwent either single APBSCT or tandem transplantation was conducted to evaluate the incidence, risk factors, and outcomes of CMV infection at a single institution. A total of 104 patients with MM underwent transplantation during the study period, including 66 patients who received tandem transplantation. The majority of patients (66 of 104; 63.5%) were CMV-seropositive, and CMV viremia was frequently detected in this subgroup (32 of 66; 48.5%). No primary CMV infections were identified. CMV reactivation was more common in recipients of tandem transplantation than in recipients of single APBSCT (P < .001). In addition, patients who developed CMV viremia were more likely to have received conditioning therapy with melphalan, bortezomib, dexamethasone, and thalidomide compared with those without CMV reactivation (P = .015). However, on multiple logistic regression analysis, only receipt of tandem transplantation was significantly associated with CMV reactivation (odds ratio, 5.112; 95% confidence interval, 1.27-20.60; P = .022). Febrile episodes of CMV viremia were observed in 17 patients (17 of 32; 53.1%), and invasive CMV disease was diagnosed in 1 patient. Our data suggest that CMV reactivation after APBSCT for MM is relatively common, and that viremia is often associated with fever. CMV surveillance should be considered, especially when tandem transplantation is performed using combination chemotherapy with high-dose melphalan.

How to select among available options for the treatment of multiple myeloma.
    Annals of oncology : official journal of the European Society for Medical Oncology, 2012, Volume: 23 Suppl 10

    The introduction of novel agents (thalidomide, bortezomib and lenalidomide) in the frontline therapy of multiple myeloma has markedly improved the outcome both in younger patients who are candidates for high-dose therapy plus autologous stem-cell transplantation (HDT/ASCT) and in elderly patients. In the HDT/ASCT paradigm, novel agents may be used as induction therapy or after HDT/ASCT as consolidation and/or maintenance therapy. It is now possible to achieve up to 70% complete plus very good partial remission after HDT/ASCT and 70% 3-year progression-free survival (PFS). However long-term non-intensive therapy may also yield high response rates and prolonged PFS. Randomized trials comparing these two strategies are underway. In elderly patients, six randomized studies show the benefit of adding thalidomide to melphalan-prednisone (MP). a large randomized trial has also shown that the combination of bortezomib-MP is superior to MP for all parameters measuring the response and outcome. Finally, the role of maintenance is currently evaluated and a randomized trial shows that low-dose lenalidomide maintenance prolongs PFS.

Stemness of B-cell progenitors in multiple myeloma bone marrow.
    Clinical cancer research : an official journal of the American Association for Cancer Research, 2012, Nov-15, Volume: 18, Issue:22

    In myeloma, B cells and plasma cells show a clonal relationship. Clonotypic B cells may represent a tumor-initiating compartment or cancer stem cell responsible for minimal residual disease in myeloma.. We report a study of 58 patients with myeloma at time of diagnosis or relapse. B cells in bone marrow were evaluated by multicolor flow cytometry and sorting. Clonality was determined by light chain and/or immunoglobulin chain gene rearrangement PCR. We also determined aldehyde dehydrogenase activity and colony formation growth. Drug sensitivity was tested with conventional and novel agents.. Marrow CD19+ cells express a light chain identical to plasma cells and are therefore termed light chain restricted (LCR). The LCR B-cell mass is small in both newly diagnosed and relapsed patients (≤ 1%). Few marrow LCR B cells (~10%) are CD19+/CD34+, with the rest being more differentiated CD19+/CD34- B cells. Marrow LCR CD19+ B cells exhibit enhanced aldehyde dehydrogenase activity versus healthy controls. Both CD19+/CD34+ and CD19+/CD34- cells showed colony formation activity, with colony growth efficiency optimized when stroma-conditioned medium was used. B-cell progenitors showed resistance to melphalan, lenalidomide, and bortezomib. Panobinostat, a histone deacetylase inhibitor, induced apoptosis of LCR B cells and CD138+ cells. LCR B cells are CD117, survivin, and Notch positive.. We propose that antigen-independent B-cell differentiation stages are involved in disease origination and progression in myeloma. Furthermore, investigations of myeloma putative stem cell progenitors may lead to novel treatments to eradicate the potential reservoir of minimal residual disease.

Evidence for different mechanisms of 'unhooking' for melphalan and cisplatin-induced DNA interstrand cross-links in vitro and in clinical acquired resistant tumour samples.
    BMC cancer, 2012, Sep-28, Volume: 12

    DNA interstrand cross-links (ICLs) are critical lesions produced by several cancer chemotherapy agents including platinum drugs and nitrogen mustards. We have previously shown in haematological (multiple myeloma) and solid tumours (ovarian cancer) that clinical sensitivity to such agents can result from a defect in DNA ICL processing leading to their persistence. Conversely, enhanced repair can result in clinical acquired resistance following chemotherapy. The repair of ICLs is complex but it is assumed that the 'unhooking' step is common to all ICLs.. Using a modification of the single cell gel electrophoresis (Comet) assay we measured the formation and unhooking of melphalan and cisplatin-induced ICLs in cell lines and clinical samples. DNA damage response in the form of γ-H2AX foci formation and the formation of RAD51 foci as a marker of homologous recombination were also determined. Real-time PCR of 84 genes involved in DNA damage signalling pathways was also examined pre- and post-treatment.. Plasma cells from multiple myeloma patients known to be clinically resistant to melphalan showed significant unhooking of melphalan-induced ICLs at 48 hours, but did not unhook cisplatin-induced ICLs. In ovarian cancer cells obtained from patients following platinum-based chemotherapy, unhooking of cisplatin-induced ICLs was observed at 48 hours, but no unhooking of melphalan-induced ICLs. In vitro, A549 cells were proficient at unhooking both melphalan and cisplatin-induced ICLs. γ-H2AX foci formation closely followed the formation of ICLs for both drugs, and rapidly declined following the peak of formation. RPMI8226 cells unhooked melphalan, but not cisplatin-induced ICLs. In these cells, although cross-links form with cisplatin, the γ-H2AX response is weak. In A549 cells, addition of 3nM gemcitabine resulted in complete inhibition of cisplatin-induced ICL unhooking but no effect on repair of melphalan ICLs. The RAD51 foci response was both drug and cell line specific. Real time PCR studies highlighted differences in the damage response to melphalan and cisplatin following equi-ICL forming doses.. These data suggest that the mechanisms by which melphalan and cisplatin-induced ICLs are 'unhooked' in vitro are distinct, and the mechanisms of clinical acquired resistance involving repair of ICLs, are drug specific.

Residual malignant and normal plasma cells shortly after high dose melphalan and stem cell transplantation. Highlight of a putative therapeutic window in Multiple Myeloma?
    Oncotarget, 2012, Volume: 3, Issue:11

    Multiple Myeloma (MM) is an incurable malignant plasma cell disorder. We have evaluated the counts of Multiple Myeloma Cells (MMCs) and normal plasma cells (N-PCs), seven days after high-dose melphalan (HDM) and autologous stem transplantation (ASCT). Two third of patients had detectable minimal residual disease (MRD+) (71.7 MMCs/µL) after induction treatment with dexamethasone and proteasome inhibitor. MMC counts were reduced by 92% (P ≤ .05) but not eradicated 7 days after HDM+ASCT. Post-HDM+ASCT MMCs were viable and bathed in a burst of MMC growth factors, linked with post-HDM aplasia. In one third of patients (MRD- patients), MMCs were not detectable after induction treatment and remained undetectable after HDM+ASCT. Major difference between MRD- and MRD+ patients is that N-PC counts were increased 3 fold (P〈.05) by HDM+ASCT in MRD- patients, but were unaffected in MRD+ patients. Possible explanation could be that clearance of MMCs in MRD- patients makes more niches available for N-PCs. Thus, MMCs are not fully eradicated shortly after HDM, are bathed in high concentrations of MMC growth factors in an almost desert BM, are viable in short-term culture, which suggests providing additional therapies shortly after HDM to kill resistant MMCs before full repair of lesions.

    We describe 41 cases of myeloid neoplasms (MNs) secondary to plasma cell myeloma (PCM). The types of MN included myelodysplastic syndrome (MDS) in 34 (82.9%), acute myeloid leukemia (AML) in 4 (9.8%), and myeloproliferative neoplasm (MPN) or MDS/MPN in 3 (7.3%) cases. The latency from treatment to diagnosis of MN ranged from 9 to 384 months, with a median of 60 months. Of 37 cases with cytogenetic studies, complex abnormalities were detected in 22 (59.5%), -5(q)/-7(q) in 4 (10.8%), other abnormalities in 8 (21.6%), and normal karyotype in 3 (8.1%) cases. Complex abnormalities and -5(q)/-7(q) correlated directly with multiple chemotherapeutic regimens, particularly with combined melphalan/cyclophosphamide. Moreover, the features of cytogenetic abnormalities in our series were significantly different from those with concomitant PCM/MN who had significantly lower complex abnormalities. The latency, skewed proportion of MDS, and bias toward complex cytogenetic abnormalities/unbalanced aberrations of chromosomes 5/7 suggested an alkylating mutagenic effect on pathogenesis of secondary MN. Kaplan-Meier survival analysis demonstrated a median survival of 19 months, which was better than that for therapy-related (t)-MDS/AML. In contrast to t-MDS, the survival in our patients appeared to depend on subtypes of MDS as seen in de novo diseases.

[Fatal hepatic failure due to AL amyloidosis in a patient with multiple myeloma].
    [Rinsho ketsueki] The Japanese journal of clinical hematology, 2012, Volume: 53, Issue:11

    Although about 10 to 15% of patients with multiple myeloma (MM) develop AL amyloidosis, liver-restricted fatal amyloidosis is rare. We encountered such an MM patient. A 73-year-old female without a history of carpal tunnel syndrome was diagnosed with IgG-κ MM (Stage I by Durie & Salmon) in January, 2005. Because MM was exacerbated to Stage III in May, 2007, VAD (vincristine, adriamycin, dexamethasone) chemotherapy was performed with minor response, despite 3 courses of this regimen. Three courses of salvage chemotherapy (cyclophosphamide+melphalan; CM) were then performed with near partial response. In March, 2008, just before the 4th cycle of CM chemotherapy, she was slightly icteric with elevated biliary tract enzymes; therefore, treatment was switched to oral cyclophosphamide and prednisolone. At this time, she did not have macroglossia, skin eruption, gastrointestinal dysfunction, or bleeding. Echocardiography was also non-specific. One month later, she developed a marked bleeding tendency and leg edema. Laboratory tests showed a severe deterioration in liver function. In the middle of May, 2008, she progressed to hepatic coma and died of intracranial hemorrhage several days later. Autopsy showed that the liver was almost substituted by AL amyloid substance.

Alterations in glutathione levels and apoptotic regulators are associated with acquisition of arsenic trioxide resistance in multiple myeloma.
    PloS one, 2012, Volume: 7, Issue:12

    Arsenic trioxide (ATO) has been tested in relapsed/refractory multiple myeloma with limited success. In order to better understand drug mechanism and resistance pathways in myeloma we generated an ATO-resistant cell line, 8226/S-ATOR05, with an IC50 that is 2-3-fold higher than control cell lines and significantly higher than clinically achievable concentrations. Interestingly we found two parallel pathways governing resistance to ATO in 8226/S-ATOR05, and the relevance of these pathways appears to be linked to the concentration of ATO used. We found changes in the expression of Bcl-2 family proteins Bfl-1 and Noxa as well as an increase in cellular glutathione (GSH) levels. At low, clinically achievable concentrations, resistance was primarily associated with an increase in expression of the anti-apoptotic protein Bfl-1 and a decrease in expression of the pro-apoptotic protein Noxa. However, as the concentration of ATO increased, elevated levels of intracellular GSH in 8226/S-ATOR05 became the primary mechanism of ATO resistance. Removal of arsenic selection resulted in a loss of the resistance phenotype, with cells becoming sensitive to high concentrations of ATO within 7 days following drug removal, indicating changes associated with high level resistance (elevated GSH) are dependent upon the presence of arsenic. Conversely, not until 50 days without arsenic did cells once again become sensitive to clinically relevant doses of ATO, coinciding with a decrease in the expression of Bfl-1. In addition we found cross-resistance to melphalan and doxorubicin in 8226/S-ATOR05, suggesting ATO-resistance pathways may also be involved in resistance to other chemotherapeutic agents used in the treatment of multiple myeloma.

Non-invasive imaging provides spatiotemporal information on disease progression and response to therapy in a murine model of multiple myeloma.
    PloS one, 2012, Volume: 7, Issue:12

    Multiple myeloma (MM) is a B-cell malignancy, where malignant plasma cells clonally expand in the bone marrow of older people, causing significant morbidity and mortality. Typical clinical symptoms include increased serum calcium levels, renal insufficiency, anemia, and bone lesions. With standard therapies, MM remains incurable; therefore, the development of new drugs or immune cell-based therapies is desirable. To advance the goal of finding a more effective treatment for MM, we aimed to develop a reliable preclinical MM mouse model applying sensitive and reproducible methods for monitoring of tumor growth and metastasis in response to therapy.. A mouse model was created by intravenously injecting bone marrow-homing mouse myeloma cells (MOPC-315.BM) that expressed luciferase into BALB/c wild type mice. The luciferase in the myeloma cells allowed in vivo tracking before and after melphalan treatment with bioluminescence imaging (BLI). Homing of MOPC-315.BM luciferase+ myeloma cells to specific tissues was examined by flow cytometry. Idiotype-specific myeloma protein serum levels were measured by ELISA. In vivo measurements were validated with histopathology.. Strong bone marrow tropism and subsequent dissemination of MOPC-315.BM luciferase(+) cells in vivo closely mimicked the human disease. In vivo BLI and later histopathological analysis revealed that 12 days of melphalan treatment slowed tumor progression and reduced MM dissemination compared to untreated controls. MOPC-315.BM luciferase(+) cells expressed CXCR4 and high levels of CD44 and α4β1 in vitro which could explain the strong bone marrow tropism. The results showed that MOPC-315.BM cells dynamically regulated homing receptor expression and depended on interactions with surrounding cells.. This study described a novel MM mouse model that facilitated convenient, reliable, and sensitive tracking of myeloma cells with whole body BLI in living animals. This model is highly suitable for monitoring the effects of different treatment regimens.

Anti-tumoral activities of dioncoquinones B and C and related naphthoquinones gained from total synthesis or isolation from plants.
    European journal of medicinal chemistry, 2011, Volume: 46, Issue:12

    Dioncoquinones belong to a family of natural naphthoquinone products of interest due to their promising anti-tumoral and anti-infective activities. In particular, dioncoquinones A (5) and B (6) have been shown to be highly active against Leishmania major and multiple myeloma cells without any significant toxicity toward normal blood cells. Their effective concentrations against multiple myeloma cell lines were similar to those of melphalan, a well known DNA-alkylating agent used in a standard therapy against B cell lymphoma and multiple myeloma. We report on the first total synthesis of the highly oxygenated anti-tumoral agent dioncoquinone B (6) and the isolation of its new, even higher-oxygenated analogs, dioncoquinones C (7), D (8), and E (9), from cell cultures of Triphyophyllum peltatum. In addition, several derivatives of these compounds were synthesized, including dioncoquinone C (7), and a small library of naphthoquinones was created. Furthermore, the first structure-activity relationship (SAR) study on this class of compounds was conducted, showing that each of the three hydroxy groups, at C-3, C-5, and C-6, is required for improved anti-tumoral activities and decreased cytotoxicities.

The histone deacetylase inhibitor LBH589 enhances the anti-myeloma effects of chemotherapy in vitro and in vivo.
    Leukemia research, 2011, Volume: 35, Issue:3

    Panobinostat (LBH589) is a potent histone deacetylase inhibitor (HDACi) that has shown anti-tumor activity in preclinical studies in both solid and hematological malignancies. We evaluated the anti-multiple myeloma (MM) effects of LBH589 alone and with melphalan or doxorubicin using MM cell lines and our human MM xenograft model LAGλ-1. LBH589 treatment resulted in increased acetylation of histones, induction of caspase cleavage, inhibition of cell proliferation and synergistic anti-MM effects with melphalan or doxorubicin in vitro. LBH589 with melphalan or doxorubicin also showed significantly enhanced anti-myeloma activity in vivo. These findings provide the basis for clinical development of these combination therapies.

Factors associated with recovery of renal function in patients with multiple myeloma who were treated with hemodialysis.
    Nephron. Clinical practice, 2011, Volume: 117, Issue:1

    The presence of renal failure in patients with multiple myeloma (MM) has been considered an ominous prognostic factor associated with a significantly decreased life expectancy. The prognostic factors have seldom been analyzed to predict discontinuation of hemodialysis (HD) therapy in MM patients with renal failure after HD initiation. It is clinically very important to predict whether HD can be discontinued after introducing HD in such patients.. All medical and HD records were reviewed in MM patients who underwent HD in the National Center for Global Health and Medicine Hospital between January 1995 and May 2009. Thirty-two patients with MM had undergone HD. The clinical features and the factors that might be associated with recovery of renal function leading to discontinuation of HD in MM patients with severe renal failure were examined.. The factors associated with recovery of renal function and discontinuation of HD were: low International Staging System (ISS) score (p = 0.0034); high response to chemotherapy (p = 0.036); low serum Ca (p = 0.006); low Cr (p = 0.019), and low serum β₂-microglobulin (sβ₂M) (p = 0.002). On multivariate analysis, low serum Ca and sβ₂M were significantly associated with HD discontinuation. Moreover, discontinuing HD was the significant factor associated with improved overall survival in MM patients who required HD at least once.. sβ₂M and Ca were the laboratory parameters that were significant, independent prognostic factors for predicting the probability of recovery from severe renal failure and discontinuation of HD in MM patients who needed HD at least once.

Pegfilgrastim reduces the length of hospitalization and the time to engraftment in multiple myeloma patients treated with melphalan 200 and auto-SCT compared with filgrastim.
    Annals of hematology, 2011, Volume: 90, Issue:1

    To reduce the duration of neutropenia after conditioning chemotherapy and autologous peripheral blood stem cell transplantation (APBSCT), granulocyte-colony stimulating factors (G-CSF) are commonly administered. We retrospectively evaluated the impact of pegfilgrastim compared to filgrastim on neutrophil engraftment, hospital stay, and supportive measures in patients with multiple myeloma after conditioning with Melphalan 200 (Mel200) followed by APBSCT. Ninety-two APBSCT after Mel200 treatment were performed in 72 patients between January 2006 and December 2009 at our institution. Patients received either single-dose pegfilgrastim (n = 46; 50%), or daily filgrastim (n = 46; 50%) after APBSCT (median duration of filgrastim use, 9 days; range, 3-14 days). Duration of neutropenia grade IV was shorter with pegfilgrastim compared with filgrastim (median, 5 days (range, 3-14 days) versus 6 days (range, 3-9 days), p = 0.0079). The length of hospitalization differed significantly (pegfilgrastim (median, 14.5 days; range, 11-47 days) versus filgrastim (median, 15.5 days; range, 12-64 days), p = 0.024). Pegfilgrastim-treated patients had less red blood cell transfusions (median, 0 transfusions (range, 0-10) versus 0.5 transfusions (range, 0-9), p = 0.00065). Pegfilgrastim was associated with reduced cost of the treatment procedure compared with filgrastim (p = 0.031). Pegfilgrastim appears to be at least equivalent to filgrastim without additional expenditure in myeloma patients treated with Mel200 and APBSCT.

Incidence and risk factors for lower alimentary tract mucositis after 1529 courses of chemotherapy in a homogenous population of oncology patients: clinical and research implications.
    Cancer, 2011, Feb-01, Volume: 117, Issue:3

    Lower alimentary tract mucositis is a serious complication of chemotherapy. The aim of the study was to determine the incidence, risk factors, and mortality of lower alimentary tract mucositis in a homogeneous population of patients with newly diagnosed myeloma receiving similar antineoplastic therapy and standardized supportive care.. Lower alimentary tract mucositis was evaluated among 303 consecutive patients with myeloma (2004-2007) enrolled in a clinical trial consisting of induction chemotherapy, tandem melphalan-based autologous stem cell transplantation (ASCT), and consolidation. Lower alimentary tract mucositis was defined as neutropenia-associated grade II-IV enteritis/colitis. Pretreatment risk factors were examined including body surface area (BSA), serum albumin (albumin), and estimated creatinine clearance (CrCl). Multiple logistic regression model was used to compute adjusted odds ratio (OR) and 95% confidence intervals (CI).. Forty-seven (15.5%) patients developed lower alimentary tract mucositis during 1529 courses of chemotherapy (including 536 melphalan-based ASCT). Pre-enrollment BSA <2 m² (OR, 2.768; 95% CI, 1.200-6.381; P = .0169) increased the risk for lower alimentary tract mucositis, whereas higher albumin was protective (OR, 0.698; 95% CI, 0.519-0.940; P = .0177). Pretransplant variables associated with lower alimentary tract mucositis were BSA <2 m² (OR, 4.451; 95% CI, 1.459-13.58, P = .0087) and estimated CrCl <60 mL/min (OR, 3.493; 95% CI, 1.173-10.40; P = .0246). Higher albumin level conferred protection (OR, 0.500; 95% CI, 0.304-0.820; P = .0061). No lower alimentary tract mucositis-related death was observed.. Lower alimentary tract mucositis is not uncommon among a homogenous population of oncology patients undergoing sequential courses of chemotherapy including melphalan-based ASCT but does not contribute to mortality. Lower BSA, renal function, and albumin are associated with increased risk for lower alimentary tract mucositis.

SCT without growth factor in multiple myeloma: engraftment kinetics, bacteremia and hospitalization.
    Bone marrow transplantation, 2011, Volume: 46, Issue:7

    SCT is important in the management of multiple myeloma. In the United States, the standard of care is administration of growth factors to accelerate neutrophil recovery after SCT. The need for growth factors after transplant has not been investigated recently. We analyzed a cohort of 166 patients at our institution who underwent autologous transplant for multiple myeloma without receiving growth factors after transplant and compared them with 498 patients who received standard filgrastim beginning on posttransplant day 5. A neutrophil count of 500/μL was achieved in a median of 12.5 days in patients receiving growth factor, compared with 13.5 days in those not receiving growth factor (P<0.001). Platelet engraftment was identical (median, 14.5 days; P=0.12) in both groups, despite a lower median number of CD34+ cells infused in patients who did not receive growth factors. Incidence of nonstaphylococcal bacteremia was identical in both groups. The median hospital stay was 3.5 days shorter in the group not receiving growth factor. It is feasible and reasonable to perform autologous SCT for multiple myeloma without administering growth factors.

Upregulation of Dicer is more frequent in monoclonal gammopathies of undetermined significance than in multiple myeloma patients and is associated with longer survival in symptomatic myeloma patients.
    Haematologica, 2011, Volume: 96, Issue:3

    Dicer and Drosha are key enzymes in the miRNA-processing pathway which is altered in many human cancers. We analyzed Dicer and Drosha expression levels by quantitative PCR in 151 patients with monoclonal gammopathies: 102 symptomatic myeloma patients, 23 smoldering myelomas and 26 monoclonal gammopathy of undetermined significance. We found that Dicer expression values were significantly higher in monoclonal gammopathy of undetermined significance than in smoldering myelomas and symptomatic myeloma (mean ± SD, 0.84 ± 0.36 vs. 0.60 ± 0.23 and 0.62 ± 0.51; P<0.01). Moreover, the median progression-free survival was significantly longer in symptomatic myeloma patients with high expression of Dicer (not reached vs. 23.6 months; P=0.02). By contrast, no differences in the expression of Drosha among these groups of patients were observed. Our data suggest that Dicer expression may play an important role in the progression and prognosis of monoclonal gammopathies.

Effect of cobalt-60 (γ radiation) on multidrug-resistant multiple myeloma cell lines.
    Cell biology international, 2011, Volume: 35, Issue:7

    Emergence of resistance to chemotherapy and radiotherapy is a major obstacle for the successful treatment of MM (multiple myeloma). Prednisone, vincristine and melphalan are commonly used chemotherapeutic agents for the treatment of MM. In the current study, we examined the presence of possible cross-resistance between these drugs and gamma (γ) radiation. Prednisone, vincristine and melphalan resistant RPMI-8226 and U-266 MM cells were generated by stepwise increasing concentrations of the drugs. The sensitive and resistant cells were exposed to 200- and 800 cGy γ radiation, and proliferation was examined by XTT {2,3-bis(2-methoxy-4-nitro-5-sulfophenyl)-5-[(phenylamino)carbonyl]-2H-tetrazolium hydroxide} assay. The results showed that Prednisone- and melphalan-resistant RPMI-8226 cells were also cross-resistant to 200 and 800 cGy γ radiation application, while vincristine-resistant cells did not show resistance. On the other hand, Prednisone-, vincristine- and melphalan-resistant U-266 cells showed cross-resistance to 200- and 800 cGy γ radiation application. These results demonstrated that MM cells resistant to anticancer agents respond to radiation in different levels. These findings may be important in the clinical applications of radiation therapy in the treatment of vincristine resistant MM.

Blockade of interleukin-6 signalling with siltuximab enhances melphalan cytotoxicity in preclinical models of multiple myeloma.
    British journal of haematology, 2011, Volume: 152, Issue:5

    Signalling through the interleukin (IL)-6 pathway induces proliferation and drug resistance of multiple myeloma cells. We therefore sought to determine whether the IL-6-neutralizing monoclonal antibody siltuximab, formerly CNTO 328, could enhance the activity of melphalan, and to examine some of the mechanisms underlying this interaction. Siltuximab increased the cytotoxicity of melphalan in KAS-6/1, INA-6, ANBL-6, and RPMI 8226 human myeloma cell lines (HMCLs) in an additive-to-synergistic manner, and sensitized resistant RPMI 8226.LR5 cells to melphalan. These anti-proliferative effects were accompanied by enhanced activation of drug-specific apoptosis in HMCLs grown in suspension, and in HMCLs co-cultured with a human-derived stromal cell line. Siltuximab with melphalan enhanced activation of caspase-8, caspase-9, and the downstream effector caspase-3 compared with either of the single agents. This increased induction of cell death occurred in association with enhanced Bak activation. Neutralization of IL-6 also suppressed signalling through the phosphoinositide 3-kinase/Akt pathway, as evidenced by decreased phosphorylation of Akt, p70 S6 kinase and 4E-BP1. Importantly, the siltuximab/melphalan regimen demonstrated enhanced anti-proliferative effects against primary plasma cells derived from patients with myeloma, monoclonal gammopathy of undetermined significance, and amyloidosis. These studies provide a rationale for translation of siltuximab into the clinic in combination with melphalan-based therapies.

Targeting autophagy augments in vitro and in vivo antimyeloma activity of DNA-damaging chemotherapy.
    Clinical cancer research : an official journal of the American Association for Cancer Research, 2011, May-15, Volume: 17, Issue:10

    Although autophagy occurs in most tumor cells following DNA damage, it is still a mystery how this DNA-damaging event turns on the autophagy machinery in multiple myeloma (MM) and how the functional status of autophagy impacts on its susceptibility to death in response to DNA-damaging chemotherapy.. We investigate the effects of DNA damage on autophagy in MM cells and elucidate its underlying molecular mechanism. Then, we examined the impacts of pharmacologic or genetic inhibition of autophagy on DNA damage-induced apoptosis. Furthermore, the antimyeloma activity of autophagy inhibitor in combination with DNA-damaging agents was evaluated in MM xenograft models.. We showed that DNA-damaging drugs, doxorubicin and melphalan, induce caspase-dependent apoptosis and concurrently trigger Beclin 1-regulated autophagy in human MM cell lines H929 and RPMI 8226. Mechanistically, association of autophagy execution proteins Beclin 1 with class III phosphoinositide 3-kinase, which is inhibited by Bcl-2 recruitment, contributes directly to the autophagic process. Importantly, targeting suppression of autophagy by minimally toxic concentrations of pharmacologic inhibitors (hydroxychloroquine and 3-methyladenine) or short hairpin RNAs against autophagy genes, Beclin 1 and Atg5, dramatically augments proapoptotic activity of DNA-damaging chemotherapy both in vitro using MM cell lines or purified patient MM cells and in vivo in a human plasmacytoma xenograft mouse model.. These data can help unravel the underlying molecular mechanism of autophagy in DNA-damaged MM cells and also provide a rationale for clinical evaluation of autophagy inhibitors in combination with DNA-damaging chemotherapy in MM.

    The novel agents including thalidomide, bortezomib and lenalidomide have been incorporated into combination regimens which are moving from the advanced/refractory setting to first-line treatment. For the majority of elderly patients, the following regimens are considered standard: melphalan+prednisone in combination with bortezomib or thalidomide and the combination of lenalidomide+low-dose dex. For transplant-eligible patients novel agents are included in the induction phase before and in the consolidation/maintenance phase after transplant. In the relapsed/refractory setting, combinations of novel agents generate the best results but cumulative toxicity is limiting. Several newer agents such as carfilzomib, pomalidomide and deacetylase inhibitors are entering phase II and III clinical trials. The place of allogeneic stem cell transplantation in the treatment of myeloma remains controversial.

[A case of aggressive multiple myeloma].
    Gan to kagaku ryoho. Cancer & chemotherapy, 2011, Volume: 38, Issue:3

    A 64-year-old male consulted our clinic due to pancytopenia. Bone marrow appearance was consistent with multiple myeloma and an IgG-κ type M component was detected on electroimmuno-diffusion of urine. MP therapy (melphalan 2 mg/ day, prednisolone 10 mg/day) was started on an outpatient basis, but the pancytopenia worsened. The patient was then admitted to our hospital, and a course of Velcade therapy (bortezomib 2. 4 mg day 1, 4, 8, 11) was started. After a course of Velcade therapy, side effects such as gastrointestinal dysfunction appeared. A month after the disruption of the chomotherapy, the patient suddenly died. The autopsy report stated that the atrial blood showed 19, 200/μL of white blood cells and 39% of plasma cells, and a slight infiltration was found in liver, kidney and vessels. Two days before death, the blood picture showed no plasma cells. The cause of death was considered to be aggressive multiple myeloma.

Spontaneous autologous graft-versus-host disease in plasma cell myeloma autograft recipients: flow cytometric analysis of hematopoietic progenitor cell grafts.
    Biology of blood and marrow transplantation : journal of the American Society for Blood and Marrow Transplantation, 2011, Volume: 17, Issue:7

    Nine plasma cell myeloma patients spontaneously developed histologically proven autologous graft-versus-host disease (GVHD) limited predominantly to the gastrointestinal tract within 1 month of initial autologous hematopoietic cell transplantation (AHCT) using high-dose melphalan conditioning. All recipients responded promptly to systemic and nonabsorbable oral corticosteroid therapy. All patients previously received systemic therapy with thalidomide, lenalidomide, or bortezomib before AHCT. Using enzymatic amplification staining-enhanced flow cytometry, we evaluated expression of selected transcription regulators, pathway molecules, and surface receptors on samples of the infused hematopoietic cell grafts. We demonstrated significantly enhanced expression of GATA-2, CD130, and CXCR4 on CD34(+) hematopoietic progenitor cells of affected patients compared with 42 unaffected AHCT controls. These 3 overexpressed markers have not been previously implicated in autologous GVHD. Although we did not specifically evaluate T cells, we postulate that exposure over time to the various immunomodulating therapies used for induction treatment affected not only the CD34(+) cells but also T cells or relevant T cell subpopulations capable of mediating GVHD. After infusion, the affected hematopoietic progenitor cells then encounter a host that has been further altered by the high-dose melphalan preparative regimen; such a situation leads to the syndrome. These surface markers could be used to develop a model to predict development of this syndrome. Autologous GVHD potentially is a serious complication of AHCT and should be considered in plasma cell myeloma patients with otherwise unexplained gastrointestinal symptoms in the immediate post-AHCT period. Prompt recognition of this condition and protracted treatment with nonabsorbable or systemic corticosteroids or the combination may lead to resolution.

Integrin β7-mediated regulation of multiple myeloma cell adhesion, migration, and invasion.
    Blood, 2011, Jun-09, Volume: 117, Issue:23

    Integrin-β7 (ITGB7) mRNA is detected in multiple myeloma (MM) cells and its presence is correlated with MAF gene activation. Although the involvement of several integrin family members in MM-stoma cell interaction is well documented, the specific biologic functions regulated by integrin-β7 in MM are largely unknown. Clinically, we have correlated integrin-β7 expression in MM with poor survival outcomes post autologous stem cell transplantation and postsalvage therapy with bortezomib. Functionally, we have found that shRNA-mediated silencing of ITGB7 reduces MM-cell adhesion to extra-cellular matrix elements (fibronectin, E-cadherin) and reverses cell-adhesion-mediated drug resistance (CAM-DR) sensitizing them to bortezomib and melphalan. In addition, ITGB7 silencing abrogated MM-cell transwell migration in response to SDF1α gradients, reduced vessel density in xenografted tumors, and altered MM cells in vivo homing into the BM. Mechanistically, ITGB7 knockdown inhibited focal adhesion kinase (FAK) and Src phosphorylation, Rac1 activation, and SUMOylation, reduced VEGF production in MM-BM stem cell cocultures and attenuated p65-NF-κB activity. Our findings support a role for integrin-β7 in MM-cell adhesion, migration, and BM homing, and pave the way for a novel therapeutic approach targeting this molecule.

Long-term follow-up of a comparison of nonmyeloablative allografting with autografting for newly diagnosed myeloma.
    Blood, 2011, Jun-16, Volume: 117, Issue:24

    Before the introduction of new drugs, we designed a trial where treatment of newly diagnosed myeloma patients was based on the presence or absence of HLA-identical siblings. First-line treatments included a cytoreductive autograft followed by a nonmyeloablative allograft or a second melphalan-based autograft. Here, we report long-term clinical outcomes and discuss them in the light of the recent remarkable advancements in the treatment of myeloma. After a median follow-up of 7 years, median overall survival (OS) was not reached (P = .001) and event-free survival (EFS) was 2.8 years (P = .005) for 80 patients with HLA-identical siblings and 4.25 and 2.4 years for 82 without, respectively. Median OS was not reached (P = .02) and EFS was 39 months (P = .02) in the 58 patients who received a nonmyeloablative allograft whereas OS was 5.3 years and EFS 33 months in the 46 who received 2 high-dose melphalan autografts. Among patients who reached complete remission in these 2 cohorts, 53% and 19% are in continuous complete remission. Among relapsed patients rescued with "new drugs," median OS from the start of salvage therapy was not reached and was 1.7 (P = .01) years, respectively. Allografting conferred a long-term survival and disease-free advantage over standard autografting in this comparative study.

History of multiple myeloma.
    Recent results in cancer research. Fortschritte der Krebsforschung. Progres dans les recherches sur le cancer, 2011, Volume: 183

    Multiple Myeloma has been recognized since Ancient Times. The first well-documented case was reported in 1844 by Samuel Solly. The most commonly recognized case is that of Thomas Alexander McBean, a highly respectable tradesman from London in 1850. Mr. McBean excreted a large amount of protein that was described by Henry Bence Jones in the middle of the 19th century. Jones was a well-known physician and made many contributions to medicine. One of the best known cases of multiple myeloma was that of Dr. Loos that was reported by Otto Kahler. The recognition of plasma cells and subsequently their product, a monoclonal protein has been described in detail. The authors have reviewed the treatment of multiple myeloma including the novel agents, thalidomide, bortezomib and lenalidomide.

Melphalan 100 mg/m2 with stem cell support as first relapse treatment is safe and effective for myeloma patients with long remission after autologous stem cell transplantation.
    European journal of haematology, 2011, Volume: 87, Issue:2

    Today, a number of therapeutic options are available as the patient with myeloma relapses from initial treatment with high-dose melphalan and autologous stem cell transplantation (ASCT). For patients who experience a durable response to primary ASCT, retreatment with high-dose melphalan is recommended by many current guidelines. Yet, toxicity is an important aspect in the choice of relapse treatment, and a second ASCT in this setting could be associated with enhanced toxicity. As the goal for the treatment for relapsed myeloma should be disease control while maintaining quality of life, lower doses of melphalan might be preferable.. In this retrospective study, we account for the outcome of 66 patients with myeloma in first systemic relapse after ASCT, who were treated with intermediate-dose melphalan, 100 mg/m2, and stem cell support (MEL 100). The aim was to evaluate this treatment in relation to prior response duration after initial ASCT and with respect to response rate, toxicity and survival.. The overall response rate was 62%. There was limited, mostly haematological, toxicity, and no treatment-related mortality was observed. The median progression-free survival (PFS) was 8.5 months, and the median overall survival was 24 months. Patients with time to progression of 34 months or more (n=17; ≥75th percentile) after initial ASCT had a median PFS of 12.5 months after MEL 100.. For patients with a long-lasting response after ASCT, MEL 100 could be a therapeutic option with low toxicity and with efficacy comparable to newer immunomodulatory drugs.

Generation of a predictive melphalan resistance index by drug screen of B-cell cancer cell lines.
    PloS one, 2011, Apr-29, Volume: 6, Issue:4

    Recent reports indicate that in vitro drug screens combined with gene expression profiles (GEP) of cancer cell lines may generate informative signatures predicting the clinical outcome of chemotherapy. In multiple myeloma (MM) a range of new drugs have been introduced and now challenge conventional therapy including high dose melphalan. Consequently, the generation of predictive signatures for response to melphalan may have a clinical impact. The hypothesis is that melphalan screens and GEPs of B-cell cancer cell lines combined with multivariate statistics may provide predictive clinical information.. Microarray based GEPs and a melphalan growth inhibition screen of 59 cancer cell lines were downloaded from the National Cancer Institute database. Equivalent data were generated for 18 B-cell cancer cell lines. Linear discriminant analyses (LDA), sparse partial least squares (SPLS) and pairwise comparisons of cell line data were used to build resistance signatures from both cell line panels. A melphalan resistance index was defined and estimated for each MM patient in a publicly available clinical data set and evaluated retrospectively by Cox proportional hazards and Kaplan-Meier survival analysis.. Both cell line panels performed well with respect to internal validation of the SPLS approach but only the B-cell panel was able to predict a significantly higher risk of relapse and death with increasing resistance index in the clinical data sets. The most sensitive and resistant cell lines, MOLP-2 and RPMI-8226 LR5, respectively, had high leverage, which suggests their differentially expressed genes to possess important predictive value.. The present study presents a melphalan resistance index generated by analysis of a B-cell panel of cancer cell lines. However, the resistance index needs to be functionally validated and correlated to known MM biomarkers in independent data sets in order to better understand the mechanism underlying the preparedness to melphalan resistance.

CD4(+) CD28(+) lymphocytes on day 5 after high-dose melphalan for multiple myeloma predict a low risk of infections during severe neutropenia and are associated with the number of reinfused T lymphocytes of the autologous stem cell graft.
    Cytotherapy, 2011, Volume: 13, Issue:8

    Neutropenia following high-dose chemotherapy is associated with a substantial risk of infectious complications. The aim of this study was to identify variables in residual leukocyte subsets during neutropenia that are predictive for neutropenic fever.. Residual leukocytes in the peripheral blood on day 5 after autologous blood stem cell transplantation were analyzed by three-color flow cytometry in 55 consecutive patients with multiple myeloma. Furthermore, the number of T cells transfused with the autografts was determined.. Neutrophil counts at day 5 and neutrophil engraftment were similar in patients with and without neutropenic fever. Low absolute lymphocyte, CD4(+) CD28(+) and CD45RO(+) CD28(+) counts at day 5 were associated with neutropenic fever. T-cell counts at day 5 correlated with the CD3(+) cell number in the graft.. Our data show that the absolute lymphocyte, CD4(+) CD28(+) and CD45RO(+) CD28(+) counts play a role in host defense during severe neutropenia. The T-cell number in the graft may help to identify patients at high risk of neutropenic infections.

Effect of obesity on outcomes after autologous hematopoietic stem cell transplantation for multiple myeloma.
    Biology of blood and marrow transplantation : journal of the American Society for Blood and Marrow Transplantation, 2011, Volume: 17, Issue:12

    Obesity has implications for chemotherapy dosing and selection of patients for therapy. Autologous hematopoietic stem cell transplant (AutoHCT) improves outcomes for patients with multiple myeloma, but optimal chemotherapy dosing for obese patients is poorly defined. We analyzed the outcomes of 1087 recipients of AutoHCT for myeloma reported to the CIBMTR between 1995 and 2003 who received high-dose melphalan conditioning, with or without total body irradiation (TBI). We categorized patients by body mass index (BMI) as normal, overweight, obese, or severely obese. There was no overall effect of BMI on progression-free survival (PFS), overall survival (OS), progression, or nonrelapse mortality (NRM). In patients receiving melphalan and TBI conditioning, obese and severely obese patients had superior PFS and OS compared with normal and overweight patients, but the clinical significance of this finding is unclear. More obese patients were more likely to receive a reduced dose of melphalan, but there was no evidence that melphalan or TBI dosing variability affected PFS. Therefore, current common strategies of dosing melphalan do not impair outcomes for obese patients, and obesity should not exclude patients from consideration of autologous transplantation. Further research is necessary to optimize dosing of both chemotherapy and radiation in obese patients.

    Vojnosanitetski pregled, 2011, Volume: 68, Issue:5

    In comparison to standard therapy autologous stem cell transplant (ASCT) with high doses mel-phalane has improved treatment of multiple myeloma (MM) patients. The aim of this study was to evaluate the results of treatment of MM patients in our center with ASCTconditioning with melphalane or combining busulphane, cyclophosphamide and melphalane.. We performed 62 ASCT procedures in 47 patients from 1998 till 2008. Single ASCT were performed in 32 patients (68%), after 3-6 cycles of (26% patients.. Median engraftment was on 12th day. In a 50-month follow-up period 64% patients were alive. The overall response rate (ORR), wich was reached in 38 (80%) patients, was better in the group of patients treated in the early phase of MM. Totally 25 (53%) patients were without progression in a 25-month follow-up period. Twenty patients met criteria for CR + VGPR (very good partial remission), that was 5 patients more than in the period before ASCT. Fourteen (30%) patients died and median time till death was 17 months.. The ASCT perfomed in early phase of MM after V A D induction had a significant influence onthe treatment of MM patients. Reaching CR + VGPR before and after the ASCT is predictive factor for overall survival (OS) or prolongation of period till recidive appears, progression, therapy withdrowal or death.

[High-dose chemotherapy and autologous stem cell transplantation in multiple myeloma patients--single center experience].
    Przeglad lekarski, 2011, Volume: 68, Issue:2

    Multiple myeloma (MM) is one of the hematologic malignancies in which the impact of dose intensity has been demonstrated. In 2005 it was the most common disease for which autologous stem cell transplantation (ASCT) was performed. However, ASCT is not curative, and most patients relapse within a median of 3 years, the introduction of high-dose therapy resulted in prolonged survival. Novel agents such as thalidomide, bortezomib, or lenalidomide have been introduced to improve high-dose therapy outcome. From April 1998 to December 2008, 65 patients with MM underwent in our Department high-dose chemotherapy supported by autologous transplantation of peripheral blood stem cells (APBSCT). Transplantation of progenitor cells was conducted as consolidation of first line treatment in the majority of patients. Double transplantation was performed in 20 patients (31%). Conditioning regimen consisted of high-dose melphalan (200 mg/m2), in the second procedure the dose of melphalan was reduced to 140 mg/m2. Transplant related mortality was not observed. The duration of hematological recovery after first and second transplantation did not differ significantly. At the time of the analysis (June 2009) 51/65 (78.5%) patients are alive, 14/65 (21.5%) died due to disease progression. Median overall survival (OS) and progression free survival ( PFS) obtained were 86 (range 24-128) and 33 (range 4-110) months respectively. This retrospective analysis confirms the efficacy and safety of APBST in multiple myeloma patients.

The novel JAK inhibitor CYT387 suppresses multiple signalling pathways, prevents proliferation and induces apoptosis in phenotypically diverse myeloma cells.
    Leukemia, 2011, Volume: 25, Issue:12

    Janus kinases (JAKs) are involved in various signalling pathways exploited by malignant cells. In multiple myeloma (MM), the interleukin-6/JAK/signal transducers and activators of transcription (IL-6/JAK/STAT) pathway has been the focus of research for a number of years and IL-6 has an established role in MM drug resistance. JAKs therefore make a rational drug target for anti-MM therapy. CYT387 is a novel, orally bioavailable JAK1/2 inhibitor, which has recently been described. This preclinical evaluation of CYT387 for treatment of MM demonstrated that CYT387 was able to prevent IL-6-induced phosphorylation of STAT3 and greatly decrease IL-6- and insulin-like growth factor-1-induced phosphorylation of AKT and extracellular signal-regulated kinase in human myeloma cell lines (HMCL). CYT387 inhibited MM proliferation in a time- and dose-dependent manner in 6/8 HMCL, and this was not abrogated by the addition of exogenous IL-6 (3/3 HMCL). Cell cycling was inhibited with a G(2)/M accumulation of cells, and apoptosis was induced by CYT387 in all HMCL tested (3/3). CYT387 synergised in killing HMCL when used in combination with the conventional anti-MM therapies melphalan and bortezomib. Importantly, apoptosis was also induced in primary patient MM cells (n=6) with CYT387 as a single agent, and again synergy was seen when combined with conventional therapies.

Monitoring a nuclear factor-κB signature of drug resistance in multiple myeloma.
    Molecular & cellular proteomics : MCP, 2011, Volume: 10, Issue:11

    The emergence of acquired drug resistance results from multiple compensatory mechanisms acting to prevent cell death. Simultaneous monitoring of proteins involved in drug resistance is a major challenge for both elucidation of the underlying biology and development of candidate biomarkers for assessment of personalized cancer therapy. Here, we have utilized an integrated analytical platform based on SDS-PAGE protein fractionation prior to liquid chromatography coupled to multiple reaction monitoring mass spectrometry, a versatile and powerful tool for targeted quantification of proteins in complex matrices, to evaluate a well-characterized model system of melphalan resistance in multiple myeloma (MM). Quantitative assays were developed to measure protein expression related to signaling events and biological processes relevant to melphalan resistance in multiple myeloma, specifically: nuclear factor-κB subunits, members of the Bcl-2 family of apoptosis-regulating proteins, and Fanconi Anemia DNA repair components. SDS-PAGE protein fractionation prior to liquid chromatography coupled to multiple reaction monitoring methods were developed for quantification of these selected target proteins in amounts of material compatible with direct translation to clinical specimens (i.e. less than 50,000 cells). As proof of principle, both relative and absolute quantification were performed on cell line models of MM to compare protein expression before and after drug treatment in naïve cells and in drug resistant cells; these liquid chromatography-multiple reaction monitoring results are compared with existing literature and Western blots. The initial stage of a systems biology platform for examining drug resistance in MM has been implemented in cell line models and has been translated to MM cells isolated from a patient. The ultimate application of this platform could assist in clinical decision-making for individualized patient treatment. Although these specific assays have been developed to monitor MM, these techniques are expected to have broad applicability in cancer and other types of disease.

A combination of melphalan, prednisone, and 50 mg thalidomide treatment in non-transplant-candidate patients with newly diagnosed multiple myeloma.
    The Korean journal of internal medicine, 2011, Volume: 26, Issue:4

    The clinical efficacy and safety of a three-drug combination of melphalan, prednisone, and thalidomide were assessed in patients with multiple myeloma who were not candidates for high-dose therapy as a first-line treatment. Because the side effects of thalidomide at a dose of ≥ 100 mg daily can be a barrier to effective treatment for these patients, we evaluated the efficacy and safety of a reduced dose of thalidomide, 50 mg, for non-transplant candidates.. Twenty-one patients were treated in 4-week cycles, receiving 4 mg/m(2) melphalan and 40 mg/m(2) prednisone on days 1-7 and 50 mg thalidomide daily. The primary efficacy outcome was the overall response rate. Aspirin (100 mg daily) was also provided as prophylactic treatment for thromboembolism.. The overall response rate was 57.1%; a complete response was seen in 23.8% of patients, a partial response in 33.3%, and stable disease in 9.5%. After a median follow-up time of 16.1 months, the median time to progression was 11.4 months (95% confidence interval, 2.1 to 20.6); the median overall survival was not reached. Grades 3 and 4 adverse events included infection (10%), peripheral neuropathy (5%), diarrhea (5%), thrombosis (10%), and loss of consciousness (10%). Two patients discontinued treatment due to loss of consciousness and neuropathy.. Low-dose thalidomide (50 mg) plus melphalan and prednisone is an effective combination drug therapy option for newly diagnosed myeloma patients who are ineligible for high-dose chemotherapy.

Timing of the high-dose therapy in the area of new drugs.
    Srpski arhiv za celokupno lekarstvo, 2011, Volume: 139 Suppl 2

    The treatment approach in patients with multiple myeloma (MM) has been essentially changed with introduction of novel agents such as thalidomide, bortezomib and lenalidomide. In patients eligible for autologous stem cell transplant, combinations of novel agents with chemotherapy have been recognized as induction regimens. New induction regimens have significantly increased the rate of complete remission before and after autologous stem cell transplant with positive impact on the length of progression-free survival followed by the possibility for further improvement with the application of consolidation or use of thalidomide and lenalidomide as maintenance therapy. These results offer new perspectives in the treatment of MM with a reasonable hope of cure.

[New concept of the treatment in elderly patients with multiple myeloma].
    Srpski arhiv za celokupno lekarstvo, 2011, Volume: 139 Suppl 2

    The traditional concept of treatment of patients aged over 65 years with multiple myeloma is historical combination of melphalan and prednisone (MP). The introduction of novel agents, such as immunomodulatory drugs and proteasome inhibitors, has crucially changed the course and prognosis of this disease. The new gold standard of treatment in elderly patients with multiple myeloma is based on synergistic combination of standard MP chemotherapy and novel agents such as thalidomide and bortezomib, as a part of MPT and MVP regimens. Furthermore, promising results have been also obtained with MP plus new generation of immunomodulatory drug lenalidomide. In some patients aged over 65 years and in good general condition, reduced-intensity autologous stem cell transplantation can be an option with application of reduced intensity conditioning regimens and novel agents incorporated into pre-transplant induction treatment and post-transplant consolidation. Certain concern regarding treatment-related adverse events can be overcome by adequate prophylaxis, conscientious follow-up, timely dose-reduction, and application of reduced-intensity MPT and MPV in patients aged over 75 years. The last therapy of choice should be individually tailored according to the clinical profile of the patient and expected toxic effects of planned treatment.

Unrelated stem cell transplantation after reduced intensity conditioning for patients with multiple myeloma relapsing after autologous transplantation.
    British journal of haematology, 2010, Volume: 148, Issue:2

    From 2002 to 2007, 49 myeloma patients who relapsed following autologous SCT were included in a prospective multicenter trial to determine the efficacy of a reduced melphalan/fludarabine regimen followed by allogeneic SCT from unrelated donors. All patients showed leucocyte and platelet engraftment after a median of 15 and 19 d, respectively. Grade II-IV acute graft-versus-host disease (GvHD) occurred in 25% of patients and 35% had chronic GvHD. Overall response rate at day 100 was 95% including 46% complete remission (CR). Cumulative incidence of non-relapse mortality at 1 year was 25% [95% confidence interval (CI): 13-37%] and was significantly lower for human leucocyte antigen (HLA)-matched compared to -mismatched SCT (10% vs. 53%, P = 0.001). The cumulative incidence of relapse at 3 years was 55% (95% CI: 40-70%). After a median follow up of 43 months, the estimated 5-year progression-free and overall survival rates were 20% and 26% respectively and were significantly better for matched in CR at day 100 (41% vs. 7%, P = 0.04 and 56% vs. 16%, P = 0.02). We conclude that optimal donor selection is mandatory for a low non-relapse mortality and high relapse incidence, which remains a major concern, should be improved by including post-transplant strategies to upgrade remission status.

Salvage treatment with upfront melphalan 100 mg/m(2) and consolidation with novel drugs for fulminant progression of multiple myeloma.
    Annals of hematology, 2010, Volume: 89, Issue:5

    Patients (pts) with fulminant progression (FPG) of multiple myeloma (MM) after autologous stem cell transplantation (ASCT) have poor prognosis. Pancytopenia, extramedullary disease, and/or renal impairment are often present, and treatment options are limited. We have retrospectively evaluated 31 pts with FPG of MM after ASCT who were treated upfront salvage therapy with melphalan 100 mg/m(2) (MEL 100) followed by PBSC support and consolidation therapy using regimens containing thalidomide (n = 16) or bortezomib (n = 15). The overall response rate (ORR) was 58% (18/31). After MEL 100, one patient achieved complete remission (3%), 26% of pts very good partial remission, 29% of pts partial remission, and 42% of pts stable disease. Progression within 3 months after MEL 100 occurred in 35% of pts. The median follow-up from MEL 100 was 8 months. The median TTP was 5 months (range, 2-15 months), and the median OS was 8 months (range, 3-23 months). There were no treatment-related deaths. In fulminant progression of MM, upfront MEL 100 is a safe salvage regimen with good response rate (ORR, 58%). Treatment with upfront MEL 100 followed by a thalidomide- or bortezomib-based regimen can prolong overall survival to more than 12 months in 33% of pts with fulminant progression of MM.

Vorinostat enhances the antimyeloma effects of melphalan and bortezomib.
    European journal of haematology, 2010, Volume: 84, Issue:3

    Examine the antitumor activity of the histone deacetylase inhibitor vorinostat's antitumor activity against multiple myeloma (MM) using cell lines and a murine xenograft model.. RPMI8226, U266, and MM1S cells were cultured for 48 h in the presence of media, vorinostat, melphalan, or bortezomib alone, or combinations of vorinostat with melphalan or bortezomib. Cell proliferation was measured using the MTS [3-(4,5-dimethylthiazol-2yl)-5-(3-carboxymethoxyphenyl)-2-(4-sulfphophenyl)-2H-tetrazolium, inner salt] assay. Severe combined immunodeficient mice bearing LAGkappa-1B tumors were treated with vorinostat [30, 60, or 100 mg/kg daily for five consecutive days per week (qdx5d), 100 or 300 mg/kg daily for 2 d/wk (qdx2d)], melphalan (1, 3, or 10 mg/kg qdx1d), bortezomib (0.25 or 0.5 mg/kg qdx2d), or combinations thereof for 35 d. Tumor growth was determined via measurement of human immunoglobulin G (hIgG) levels and tumor volume.. Vorinostat enhanced the anti-MM effects of melphalan and bortezomib in vitro. Synergism was observed with vorinostat and melphalan in RPMI8226 and U266 cell lines. Vorinostat 100 mg/kg in combination with melphalan 3 mg/kg resulted in significant inhibition of tumor growth in vivo, compared with control (tumor volume P = 0.0001; hIgG P = 0.0001), single-agent vorinostat (tumor volume P = 0.0025; hIgG P = 0.0137), and single-agent melphalan (tumor volume P = 0.0043; hIgG P = 0.0426). Vorinostat also enhanced the antimyeloma effects of bortezomib in vivo. Vorinostat enhances the anti-MM activity of melphalan and bortezomib in vitro and in vivo. This study provides rationale for further evaluation of vorinostat in combination with chemotherapeutic agents and bortezomib for the treatment of MM.

Safety and efficacy of bortezomib-based regimens for multiple myeloma patients with renal impairment: a retrospective study of Italian Myeloma Network GIMEMA.
    European journal of haematology, 2010, Volume: 84, Issue:3

    Renal impairment (RI) is a severe complication throughout the course of multiple myeloma (MM). Bortezomib has been shown to be highly active in MM patients with RI. We designed this retrospective analysis to investigate the safety and efficacy of bortezomib-based therapy in 117 MM patients with RI, 14 cases required dialysis. A total of 603 cycles of bortezomib were administered (median number, five cycles/patient). Ten patients required early discontinuation of bortezomib because of WHO grade IV toxicity. The rate of bortezomib discontinuation in cases with severe, moderate and mild RI was 11%, 5% and 0%, respectively (P = NS). Overall, 91 episodes of WHO grade III/IV toxicity were observed. At least a partial response was documented in 83/113 evaluable patients (73%), including complete response (19%) and near complete response (8%). The overall response rate was similar across RI subgroups. Reversal of RI was documented in 41% of patients after a median of 2.3 months (range 0.4-7.9). In three of 14 patients on dialysis, renal replacement therapy was discontinued after 1, 1 and 4 months. The 2-yr estimate of response duration and overall survival was 70% and 51%, respectively. In conclusion, bortezomib-based regimens are safe and effective and should be considered as appropriate treatment options for MM patients with any degree of RI.

The proteasome inhibitor CEP-18770 enhances the anti-myeloma activity of bortezomib and melphalan.
    British journal of haematology, 2010, Volume: 148, Issue:4

    The anti-multiple myeloma (MM) efficacy of bortezomib has led to the development of other proteasome inhibitors (PI), including CEP-18770 which has shown anti-MM effects in preclinical studies. However, the efficacy of orally (PO) or intravenously (IV) administered CEP-18770 in multiple MM models and in combination with conventional anti-MM therapies has not been evaluated. Herein, we show that CEP-18770 combined with melphalan or bortezomib induces synergistic inhibition of MM cell viability in vitro. In MM xenograft models, the addition of CEP-18770 IV to melphalan completely prevented the growth of both melphalan-sensitive and melphalan-resistant tumours. The combination of CEP-18770 IV and bortezomib induced complete regression of bortezomib-sensitive tumours and markedly delayed progression of bortezomib-resistant tumours compared to treatment with either agent alone. Single agent CEP-18770 PO also showed marked anti-MM effects in these xenograft models. These studies provide strong preclinical rationale for further development of this novel PI in the treatment of MM as a monotherapy as well as combined with either melphalan or bortezomib.

Increased plasma-immune cytokines throughout the high-dose melphalan-induced lymphodepletion in patients with multiple myeloma: a window for adoptive immunotherapy.
    Journal of immunology (Baltimore, Md. : 1950), 2010, Jan-15, Volume: 184, Issue:2

    High-dose melphalan (HDM) followed by autologous stem cell transplantation (ASCT) is a standard treatment for patients with multiple myeloma. However, lymphocyte reconstitution is impaired after HDM. Recent work has suggested that the lymphopenia period occurring after various immunosuppressive or chemotherapy treatments may provide an interesting opportunity for adoptive antitumor immunotherapy. The objective of this study was to determine an immunotherapy window after HDM and ASCT, evaluating T cell lymphopenia, and measuring circulating immune cytokine concentrations in patients with multiple myeloma. The counts of T cell subpopulations reached a nadir at day 8 post-ASCT (day 10 post-HDM) and recovered by day 30. IL-6, IL-7, and IL-15 plasma levels increased on a median day 8 post-ASCT, respectively, 35-fold, 8-fold, and 10-fold compared with pre-HDM levels (p < or = 0.05). The increases in IL-7 and IL-15 levels were inversely correlated to the absolute lymphocyte count, unlike monocyte or myeloid counts. Furthermore, we have shown that CD3 T cells present in the ASC graft are activated, die rapidly when they are cultured without cytokine in vitro, and that addition of IL-7 or IL-15 could induce their survival and proliferation. In conclusion, the early lymphodepletion period, occurring 4-11 d post-HDM and ASCT, is associated with an increase of circulating immune cytokines and could be an optimal window to enhance the survival and proliferation of polyclonal T cells present in the ASC autograft and also of specific antimyeloma T cells previously expanded in vitro.

Genetic polymorphisms associated with outcome in multiple myeloma patients receiving high-dose melphalan.
    Bone marrow transplantation, 2010, Volume: 45, Issue:8

    High-dose melphalan (HDM) is an essential component in the treatment of patients with multiple myeloma (MM). Few data are available regarding genetic polymorphisms associated with patient outcome or toxicity in this setting. To identify such polymorphisms, we performed a retrospective analysis, genotyping single nucleotide polymorphisms (SNPs) with the arrayed primer extension (APEX) technology in 169 patients having received HDM for MM. We analyzed 209 SNPs in 95 genes involved in drug metabolism, DNA repair, cell cycle and apoptosis. SNPs in ABCB1, CYP3A4 and TP53BP2 were associated with response to VAD induction therapy (P<0.01). SNPs in ALDH2, GSTT2 and BRCA1 were associated with response to HDM (P<0.01). Polymorphisms in CYP1A1, RAD51 and PARP were associated with disease progression whereas polymorphisms in ALDH2 and CYP1A1 were correlated with OS. Polymorphisms in BRCA1, CDKN1A and XRCC1 were associated with the occurrence of severe mucositis after HDM. These results suggest that SNPs of genes involved in drug metabolism or DNA repair could be used to distinguish MM patient subgroups with different toxicity/efficacy profiles.

Short and long-term outcome of treatment with high-dose melphalan and stem cell transplantation for multiple myeloma-associated AL amyloidosis.
    Annals of hematology, 2010, Volume: 89, Issue:6

    High-dose melphalan chemotherapy and autologous peripheral blood stem cell transplantation (HDM/SCT) has been shown to result in a durable hematologic response and prolonged overall survival in systemic amyloid light-chain (AL) amyloidosis as well as multiple myeloma. However, little is known about the myeloma associated with AL amyloidosis (MM/AL). In this retrospective study, we evaluated 87 patients with MM/AL from 1994 to 2007. Sixteen of these patients underwent HDM/SCT at Boston University Medical Center. Three patients (19%) died from treatment-related mortality. The overall median survival for all 87 patients was 22 months by Kaplan-Meier estimates. However, this was improved to 54.5 months for those who received HDM/SCT compared to 21 months for those who did not receive HDM/SCT. A hematologic complete response was achieved by 25% (4/16) of patients at 6 months after HDM/SCT. Hematologic relapses occurred in 60% of patients at a median of 1 year after HDM/SCT. In conclusion, HDM/SCT can prolong overall survival in patients with MM/AL who are eligible to receive it.

Synergistic action of the novel HSP90 inhibitor NVP-AUY922 with histone deacetylase inhibitors, melphalan, or doxorubicin in multiple myeloma.
    European journal of haematology, 2010, Volume: 84, Issue:4

    Heat shock protein 90 (HSP90) is a promising target for tumor therapy. The novel HSP90 inhibitor NVP-AUY922 has preclinical activity in multiple myeloma, however, little is known about effective combination partners to design clinical studies. Multiple myeloma cell lines, OPM-2, RPMI-8226, U-266, LP-1, MM1.S, and primary myeloma cells were exposed to NVP-AUY922 and one of the combination partners histone deacetylase inhibitor NVP-LBH589, suberoylanilide hydroxamic acid (SAHA), melphalan, or doxorubicin, either simultaneously or in sequential patterns. Effects on cell proliferation and apoptosis were determined. Synergistic effects were evaluated using the method of Chou and Talalay. Combined sequential incubation with NVP-AUY922 and SAHA showed that best synergistic effects were achieved with 24 h preincubation with SAHA followed by another 48 h of combination treatment. Combination of NVP-AUY922 with SAHA, NVP-LBH589, melphalan, or doxorubicin resulted in synergistic inhibition of viability, with strong synergy (combination index < 0.3) in the case of melphalan. Importantly, resistance of the RPMI-8226 cell line and relative resistance of some primary myeloma cells against NVP-AUY922 could be overcome by combination treatment. These data show impressive synergistic action of the novel HSP90 inhibitor NVP-AUY922 with melphalan, doxorubicin, NVP-LBH589, and SAHA in multiple myeloma and build the frame work for clinical trials.

Patterns of improved survival in patients with multiple myeloma in the twenty-first century: a population-based study.
    Journal of clinical oncology : official journal of the American Society of Clinical Oncology, 2010, Feb-10, Volume: 28, Issue:5

    PURPOSE Randomized multiple myeloma (MM) studies show improved response rates and better progression-free survival for newer therapies. However, a less pronounced effect has been found for overall survival (OS). Using population-based data including detailed treatment information for individual patients, we assessed survival patterns for all patients diagnosed with MM in Malmö, Sweden from 1950 to 2005. PATIENTS AND METHODS We identified 773 patients with MM (48% males). On the basis of the age limit used for treatment with high-dose melphalan with autologous stem-cell support (HDM-ASCT; < or = 65 years old) in Sweden, we constructed Kaplan-Meier curves and used the Breslow generalized Wilcoxon test to evaluate OS patterns (diagnosed in six calendar periods) for patients 65 years old or younger and patients older than 65 years. Results Including all age groups, patients diagnosed from 1960 to 1969 had a better survival than patients diagnosed from 1950 to 1959. In subsequent 10-year calendar periods, median OS increased from 24.3 to 56.3 months (P = .036) in patients < or = 65 years old. In contrast, OS did not improve among patients older than age 65 years (21.2 to 26.7 months, P = .7). CONCLUSION With the establishment of HDM-ASCT as the standard therapy for younger patients with MM, OS has improved significantly for this age group in the general MM population. With novel therapies being commonly used at disease progression, presumably it becomes increasingly difficult to confirm survival differences between defined induction, consolidation, and maintenance therapies in the future. Consequently, in the era of novel MM therapies, population-based studies will serve as a necessary complement to randomized trials.

INCB16562, a JAK1/2 selective inhibitor, is efficacious against multiple myeloma cells and reverses the protective effects of cytokine and stromal cell support.
    Neoplasia (New York, N.Y.), 2010, Volume: 12, Issue:1

    Cytokines in the bone marrow of multiple myeloma patients activate Janus kinase (JAK)/signal transducer and activator of transcription (STAT) signaling pathways in tumor cells and promote tumor growth, survival, and drug resistance. INCB16562 was developed as a novel, selective, and orally bioavailable small-molecule inhibitor of JAK1 and JAK2 markedly selective over JAK3. The specific cellular activity of the inhibitor was demonstrated by its potent and dose-dependent inhibition of cytokine-dependent JAK/STAT signaling and cell proliferation in the absence of effects on Bcr-Abl-expressing cells. Treatment of myeloma cells with INCB16562 potently inhibited interleukin-6 (IL-6)-induced phosphorylation of STAT3. Moreover, the proliferation and survival of myeloma cells dependent on IL-6 for growth, as well as the IL-6-induced growth of primary bone marrow-derived plasma cells from a multiple myeloma patient, were inhibited by INCB16562. Induction of caspase activation and apoptosis was observed and attributed, at least in part, to the suppression of Mcl-1 expression. Importantly, INCB16562 abrogated the protective effects of recombinant cytokines or bone marrow stromal cells and sensitized myeloma cells to cell death by exposure to dexamethasone, melphalan, or bortezomib. Oral administration of INCB16562 antagonized the growth of myeloma xenografts in mice and enhanced the antitumor activity of relevant agents in combination studies. Taken together, these data suggest that INCB16562 is a potent JAK1/2 inhibitor and that mitigation of JAK/STAT signaling by targeting JAK1 and JAK2 will be beneficial in the treatment of myeloma patients, particularly in combination with other agents.

IGF-1 suppresses Bim expression in multiple myeloma via epigenetic and posttranslational mechanisms.
    Blood, 2010, Mar-25, Volume: 115, Issue:12

    Insulin-like growth factor-1 (IGF-1) is an important growth and survival factor in multiple myeloma (MM). Here, we demonstrate that IGF-1 induces significant down-regulation of the proapoptotic BH3-only protein Bim in MM cells. Reduced Bim levels by RNA interference (RNAi) protected cells from drug-induced cell death. The IGF-1-mediated down-regulation of Bim was the result of (1) reduced transcription by activation of the Akt pathway and inactivation of the transcription factor FoxO3a, (2) increased proteasome-mediated degradation of the Bim extra-long protein by activation of the mitogen-activated protein kinase pathway, and (3) epigenetic regulation of both the Bim and the FoxO3a promoter. Treatment of cells with the histone deacetylase inhibitor LBH589 resulted in a clear up-regulation in the expression of Bim. Furthermore, the methylation inhibitor 5-aza-2'deoxycytidine (decitabine) significantly increased the effects of LBH589. On IGF-1 treatment, the Bim promoter region was found to be unmethylated, whereas chromatin immunoprecipitation analysis of the IGF-1-treated cells showed both a reduced histone H3 tail Lys9 (H3K9) acetylation and an increased H3K9 dimethylation, which contributed actively to its silencing. These data identify a new mechanism in the IGF-1-dependent survival of MM cells and emphasize the need for IGF-1-targeted drug therapy.

Impedance cardiography in the diagnosis of capillary leak syndrome caused by doxorubicin therapy in a patient with myeloma multiplex.
    Cardiology journal, 2010, Volume: 17, Issue:1

    Cytotoxicity of drugs can be a cause of cardiorespiratory disorders connected with chemotherapy. Doxorubicin is an antibiotic from the group of anthracyclines effective in antineoplastic therapy of solid and hematopoetic tumors. The most common cause of therapy ceasing is its cardiotoxicity. However, a lung injury connected with its cytotoxic activity to pulmonary endothelium (capillary leak syndrome) can be an equally serious complication. In the case presented, rapid, multi-profile diagnostics with the use of impedance cardiography, a modern noninvasive tool of hemodynamic monitoring, led to the recognition and effective treatment of a rare clinical syndrome.

Use of sidestream dark-field (SDF) imaging for assessing the effects of high-dose melphalan and autologous stem cell transplantation on oral mucosal microcirculation in myeloma patients.
    Oral surgery, oral medicine, oral pathology, oral radiology, and endodontics, 2010, Volume: 109, Issue:1

    Oral mucositis (OM) is a common toxic side effect among patients receiving high-dose chemotherapy (CT) with autologous stem cell transplantation (ASCT) for hematologic malignancies. The aim of this study was to investigate changes in submucosal microcirculation in myeloma patients receiving high-dose CT with ASCT by assessing capillary density and microvascular structural integrity.. Ten consecutive patients with multiple myeloma who underwent first-time CT treatment with high-dose melphalan (200 mg/m(2)) and ASCT were included in this study. Baseline buccal mucosa capillary density, expressed as the mean number of capillaries +/- SD per mm(2) (cpll/mm(2)), was measured with sidestream dark-field imaging after treatment was performed, after 30 and 60 minutes, and then on days 2, 4, 6, 8, and 14. A linear mixed model was used to examine capillary density over time and a P value of <.05 was considered to be statistically significant.. Baseline mucosal capillary density was 19 +/- 2.4 cpll/mm(2). Mucosal capillary density after melphalan infusion after 30 and 60 minutes and on days 2 and 4 showed no statistically significant differences. A decrease in capillary density with statistical significance was observed on days 6 (10 +/- 3.0 cpll/mm(2); P < .01) and 8 (12 +/- 4.9 cpll/mm(2); P < .01). On day 14, capillary density returned to near baseline value.. High-dose CT alters microvascular structural integrity and dysregulates tissue perfusion in the oral mucosa by decreasing the number of perfused submucosal capillaries in the oral mucosa. The findings of this investigation suggest that acute CT toxicity alters oral microcirculation and may be an important mechanism responsible for driving early mucosal barrier disturbances associated with CT-induced OM.

The novel, proteasome-independent NF-kappaB inhibitor V1810 induces apoptosis and cell cycle arrest in multiple myeloma and overcomes NF-kappaB-mediated drug resistance.
    Molecular cancer therapeutics, 2010, Volume: 9, Issue:2

    Evidence is increasing that aberrant NF-kappaB activation is crucial for multiple myeloma pathophysiology and a promising target for new antimyeloma therapies. In this study, we assessed the in vitro antimyeloma activity of the novel NF-kappaB inhibitor V1810. Pharmacokinetics and toxicity were studied in vivo. In mice, V1810 plasma concentrations of 10 micromol/L can be reached without relevant toxicity. At this concentration, V1810 potently induces apoptosis in all four multiple myeloma cell lines assessed (IC(50) = 5-12 micromol/L) as well as in primary multiple myeloma cells (IC(50) = 5-40 micromol/L). Apoptosis induced by V1810 is associated with proteasome-independent inhibition of NF-kappaB signaling (41% relative reduction), downregulation of Mcl-1, and caspase 3 cleavage. In OPM2, U266, and RPMI-8226 cells, induction of apoptosis is accompanied by cell cycle arrest. Western blots revealed downregulation of Cdk4 as well as cyclin D1 (U266) or cyclin D2 (OPM2, NCI-H929, RPMI-8226), but not cyclin D3. Consistently, retinoblastoma protein was found to be hypophosphorylated. Furthermore, V1810 reverses NF-kappaB activation induced by the genotoxic drugs melphalan and doxorubicin. V1810 and melphalan synergistically decrease multiple myeloma cell viability. Taken together, the novel, proteasome-independent NF-kappaB inhibitor V1810 induces apoptosis and cell cycle arrest in multiple myeloma cells at a concentration range that can be achieved in vivo. Moreover, V1810 reverses NF-kappaB activation by alkylating drugs and overcomes NF-kappaB-mediated resistance to melphalan.

Whither the bone marrow transplant?
    Hematology (Amsterdam, Netherlands), 2010, Volume: 15, Issue:1

    Bone marrow transplantation (BMT) has become an accepted and important medical intervention which has become a routine part of medical practice. Its utility has, however, been questioned recently in a number of diseases in which its role has been clearly established on the basis that there are better non-transplant therapeutic options. The suspicion that these moves to eradicate BMT as an option may not stem from purely scientific reasons has prompted the preparation of these personal reflections. I will focus this discussion only on two diseases in which BMT has been shown to be useful: chronic myelogenous leukemia (CML) and multiple myeloma (MM).

    Thalidomide has received approval from the European Agency for the Evaluation of Medicinal Products for the treatment of newly diagnosed multiple myeloma (MM) patients older than 65 years or ineligible for transplant. The results of five phase III trials assessing thalidomide in combination with melphalan and prednisone (MPT) have demonstrated significantly improved response rates compared with melphalan and prednisone (MP) alone. Additionally, two of these studies showed that survival was extended by approximately 18 months in patients treated with MPT compared with MP alone. Thalidomide, in combination with MP, is associated with adverse events (AEs) including peripheral neuropathy and venous thromboembolism. In order to optimize the efficacy of MPT, a good awareness of these AEs is imperative. This manuscript outlines both evidence- and consensus-based recommendations discussed by a panel of experts, to provide a practical guide for physicians addressing the effective management of newly diagnosed, transplant-ineligible MM patients receiving thalidomide therapy.

A 3-day short course of palifermin before HDT reduces toxicity and need for supportive care after autologous blood stem-cell transplantation in patients with multiple myeloma.
    Annals of oncology : official journal of the European Society for Medical Oncology, 2010, Volume: 21, Issue:9

    We retrospectively determined whether a 3-day short course of palifermin could reduce the toxicity of high-dose therapy (HDT) and autologous blood stem-cell transplantation (ASCT) in patients with multiple myeloma (MM).. Sixty-seven consecutive patients received 60 mug/kg palifermin for 3 days before HDT with melphalan 200 or 140 mg/m(2) for patients with renal failure (group A). Granulocyte colony-stimulating factor (G-CSF) was applied after ASCT. Data on haematopoietic reconstitution and toxicity were compared with two previously published patient groups from our institution who had received pegfilgrastim but not palifermin (group B, n = 21) and patients who had received neither palifermin nor G-CSF (group C, n = 21).. In group A, patients with renal failure had a significantly higher risk for severe mucositis (64% versus 16%, P < 0.002). Patients with normal renal function who received palifermin experienced significantly less days of hospitalisation (P < 0.05) and less need for narcotic analgesia (P < 0.05), parenteral nutrition (P < 0.05) and erythrocyte transfusions (P < 0.05) in comparison with groups B and C. Time to haematopoietic reconstitution was not compromised by the use of palifermin.. In conclusion, a short 3-day course of palifermin may be able to reduce the toxicity of HDT and ASCT in patients with MM. Patients with impaired renal function at the time of HDT need additional strategies to further reduce the incidence of severe mucositis.

Tgf-Beta inhibition restores terminal osteoblast differentiation to suppress myeloma growth.
    PloS one, 2010, Mar-25, Volume: 5, Issue:3

    Multiple myeloma (MM) expands almost exclusively in the bone marrow and generates devastating bone lesions, in which bone formation is impaired and osteoclastic bone resorption is enhanced. TGF-beta, a potent inhibitor of terminal osteoblast (OB) differentiation, is abundantly deposited in the bone matrix, and released and activated by the enhanced bone resorption in MM. The present study was therefore undertaken to clarify the role of TGF-beta and its inhibition in bone formation and tumor growth in MM.. TGF-beta suppressed OB differentiation from bone marrow stromal cells and MC3T3-E1 preosteoblastic cells, and also inhibited adipogenesis from C3H10T1/2 immature mesenchymal cells, suggesting differentiation arrest by TGF-beta. Inhibitors for a TGF-beta type I receptor kinase, SB431542 and Ki26894, potently enhanced OB differentiation from bone marrow stromal cells as well as MC3T3-E1 cells. The TGF-beta inhibition was able to restore OB differentiation suppressed by MM cell conditioned medium as well as bone marrow plasma from MM patients. Interestingly, TGF-beta inhibition expedited OB differentiation in parallel with suppression of MM cell growth. The anti-MM activity was elaborated exclusively by terminally differentiated OBs, which potentiated the cytotoxic effects of melphalan and dexamethasone on MM cells. Furthermore, TGF-beta inhibition was able to suppress MM cell growth within the bone marrow while preventing bone destruction in MM-bearing animal models.. The present study demonstrates that TGF-beta inhibition releases stromal cells from their differentiation arrest by MM and facilitates the formation of terminally differentiated OBs, and that terminally differentiated OBs inhibit MM cell growth and survival and enhance the susceptibility of MM cells to anti-MM agents to overcome the drug resistance mediated by stromal cells. Therefore, TGF-beta appears to be an important therapeutic target in MM bone lesions.

Combined submyeloablative and myeloablative dose intense melphalan results in satisfactory responses with acceptable toxicity in patients with multiple myeloma.
    Biology of blood and marrow transplantation : journal of the American Society for Blood and Marrow Transplantation, 2010, Volume: 16, Issue:10

    We studied in patients with multiple myeloma (MM) the efficacy, cost-effectiveness, and toxicity of a strategy of submyeloablative doses of Mel and stem cell support in the ambulatory setting, followed by a standard myeloablative dose transplant. Patients with recently diagnosed symptomatic MM received dexamethazone to induce clinical response. Cytokine mobilized peripheral blood progenitor cells (PBPC) were split into 2 aliquots and cryopreserved. Patients then received Mel 100 mg/m(2) (Mel100) and infusion of the first PBPC aliquot in an ambulatory facility. Individuals received standard neutropenia prophylaxis and no growth factor support, but were seen regularly at the clinic until recovery. The cost of this step was calculated in a cohort of 23 patients where information for the expenditure was available. Six months later patients were conditioned in the hospital with Mel 200 mg/m(2) (Mel 200) followed by nfusion of the second aliquot. This study tested the cost, effectiveness, and the toxicity of out-patient-based transplantation, as well as the rate of response (complete remission [CR], very good partial remission [VGPR], partial remission [PR], and stable disease [SD]) and overall survival (OS) of this strategy. Twenty-six female and 16 male patients, with a median age of 53 years (range: 33-68 years) and median Salmon & Durie clinical disease stage III (range: II-III) were studied. The paraprotein was IgA in 17%, IgG in 52%, and light chains in 26%. The median harvested CD34(+) x 10(6) cells/kg was 12.03 (2.25-55.4). The median interval between the 2 transplant procedures was 239 (105-376) days. The median Karnofsky presentation score was 40%, but improved to 80% after the Mel 100 and was 90% following Mel 200. Subsequent to MEL 100 response was complete (CR) in 7 and it was VGPR in 9. Mel 100 grade 3-4 toxicity was mainly hematologic, but 15 (36%) required hospital admission for a median of 5 days. The median cost of MEL100 and corresponding supportive therapy was U.S. $2,142.35. In addition, the total median cost of those who needed admission to hospital was U.S. $6,042.78. Thus, pooling costs from patients who needed or did not need admissions the average cost of this strategy was U.S. $3,546.50 per patient. Among Mel 200 patients, except for hematologic toxicity, no patient had greater than grade 2 side effects. On completion of the program, 20 (48%) patients achieved CR, a further 14 (33%) had VGPR, whereas 6 had PR. At a median follow-up of

Rapid control of previously untreated multiple myeloma with bortezomib-lenalidomide-dexamethasone (BLD).
    Hematology (Amsterdam, Netherlands), 2010, Volume: 15, Issue:2

    Between April 2006 and June 2009, 34 newly diagnosed patients with multiple myeloma received one to three courses of bortezomib 1.3 mg/m(2) i.v. four times, lenalidomide 25 mg p.o. daily for 21 days and dexamethasone 20 mg/m(2) p.o. for 4 days beginning on days 1, 9 and 17 (BLD). There was rapid onset of remission in 30 patients (88%) similar to the frequency of 87% induced by a previous combination of bortezomib-thalidomide-dexamethasone (BTD). After a median of 3.6 months, 28 patients received intensive therapy with high-dose melphalan supported by autologous blood stem cells, so that the overall frequency of complete remission (CR) was 44%, similar to the frequency of 37% observed previously. Side effects due to thalidomide with previous BTD were less frequent and severe with BLD. The combination of BLD given for one or two courses was an effective primary treatment for newly diagnosed patients with multiple myeloma.

HDAC inhibition synergistically enhances alkylator-induced DNA damage responses and apoptosis in multiple myeloma cells.
    Cancer letters, 2010, Oct-28, Volume: 296, Issue:2

    Histone deacetylase (HDAC) inhibitors induce chromatin destabilization. We sought to determine whether HDAC inhibition may amplify alkylator-induced mitotic cell death in multiple myeloma (MM) cells. The combination of SNDX-275, a class I HDAC inhibitor, with melphalan, showed a powerful synergism on growth inhibition with the combination index ranged from 0.27 to 0.75 in MM1.S and RPMI8226 cells. Their combinations as compared with either agent alone promoted much more caspase-dependent apoptosis. Flow cytometry analysis showed that SNDX-275 had minimal effects on cell cycle progression of MM1.S cells, but clearly increased the percentage of S phase in RPMI8226 cells associated with an upregulation in p21(waf1) and a reduction in cyclin D1 and E2F1. Melphalan alone significantly arrested both MM1.S and RPMI8226 cells at S phase and enhanced expression of p53 and p21(waf1). Furthermore, studies on DNA damage response revealed that phospho-histone H2A.X (gammaH2A.X), a hall marker of DNA double strand break, along with phosphorylated CHK1 (P-CHK1) and CHK2 (P-CHK2) was dramatically induced by SNDX-275 or melphalan. The increase in gammaH2A.X and P-CHK1 was considerably higher on combination than either agent alone. These molecular changes correlated well with the significant increase in mitotic catastrophe. Our data indicate that SNDX-275 synergistically enhances melphalan-induced apoptosis in MM cells via intensification of DNA damage, suggesting that SNDX-275 in combination with melphalan may be a novel therapeutic strategy for MM.

[Serum free light-chain assay for nonsecretory multiple myeloma with light chain cast nephropathy and light chain deposition disease].
    [Rinsho ketsueki] The Japanese journal of clinical hematology, 2010, Volume: 51, Issue:4

    Quantitative assay for serum free light chains (sFLC) is reported as a useful test for diagnosis and monitoring of patients with nonsecretory multiple myeloma (NSM). We performed serial sFLC assays in a patient with NSM with light chain cast nephropathy (LCCN) and light chain deposition disease (LCDD). After 3 cycles of VAD induction therapy, while plasma cells in the marrow decreased from 93.0% to 0.2%, sFLCkappa/lambda ratio remained abnormal. Flow cytometry assay also showed that these plasma cells were CD19 negative. After the subsequent high dose melphalan therapy followed by autologous peripheral blood stem cell transplantation (PBSCT), the sFLCkappa/lambda ratio returned to normal and the patient achieved a stringent complete response (sCR). One year after PBSCT, the patient remained in sCR with improved renal function. The quantitative FLC assay was useful for the diagnosis and monitoring of NSM and LCDD in this patient.

Reactivation of hepatitis B virus in HBsAg-negative patients with multiple myeloma: two case reports.
    International journal of hematology, 2010, Volume: 91, Issue:5

    It was recently reported that hepatitis B virus (HBV) reactivation had occurred in HBsAg-negative lymphoma patients who received rituximab plus steroid combination chemotherapy. HBV reactivation in myeloma patients have not been reported extensively. We describe here two cases of HBV reactivation in HBsAg-negative myeloma patients receiving systemic chemotherapy: one from the medical records of 40 patients and another from 61 patients with prospective HBV-DNA monitoring. In the first case positive for anti-HBs, HBV reactivation was diagnosed when hepatitis developed during conventional chemotherapy such as MP and MCP regimen in a relapsed patient after autologous stem cell transplantation (APBSCT); in the second case positive for anti-HBc and anti-HBs, elevation of HBV-DNA was recognized by serial HBV-DNA monitoring performed prospectively following APBSCT. Interestingly, these two cases had the reduction of the titer of anti-HBs during the treatment, followed by HBV reactivation. These clinical data suggest that the HBV-DNA monitoring is necessary for not only HBsAg-positive but also HBsAg-negative myeloma patients with anti-HBc-positive and/or anti-HBs-positive following transplantation and after conventional chemotherapy in the salvage setting. Establishment of a standard strategy to prevent HBV reactivation is important for myeloma patients receiving systemic chemotherapy.

Lenalidomide plus dexamethasone vs. lenalidomide plus melphalan and prednisone: a retrospective study in newly diagnosed elderly myeloma.
    European journal of haematology, 2010, Volume: 85, Issue:3

    The goal of this retrospective study was to compare the efficacy and toxicity of lenalidomide-dexamethasone (len/dex) vs. melphalan-prednisone-lenalidomide (MPR) as upfront therapy for newly diagnosed elderly patients with myeloma.. Data from 51 patients enrolled in an Italian phase I/II trial and treated with MPR were analyzed and compared with data from 38 patients, seen at the Mayo Clinic, treated with len/dex and enrolled in phase II/III trials.. On intention-to-treat analysis, time to progression (median: 24.7 vs. 27.5 months in MPR and len/dex groups, respectively, P = 0.903), progression-free survival (median: 24.7 vs. 27.5 months in MPR and len/dex groups, respectively, P = 0.926), and overall survival (2-yr overall survival: 86.2% in MPR vs. 89.1% in len/dex, P = 0.730) were not significantly different between the two groups. Results were confirmed when the analysis was restricted to MPR and len/dex matched pair mates. Hematologic grade 3-4 toxicities were more common with MPR (neutropenia: 66.7% vs. 21.1%, P < 0.001; thrombocytopenia: 31.4% vs. 2.6%, P < 0.001). Grade 3-4 gastrointestinal events (13.2% vs. 3.9%, P = 0.132), thrombotic events (13.2% vs. 5.9%, P = 0.279), and fatigue (10.5% vs. 3.9%, P = 0.395) were more common with len/dex.. Results show that both MPR and len/dex are efficacious regimens for elderly patients with myeloma. Randomized trials are needed to confirm these results.

Melphalan, prednisone, and thalidomide versus thalidomide, dexamethasone, and pegylated liposomal doxorubicin regimen in very elderly patients with multiple myeloma: a case-match study.
    Leukemia & lymphoma, 2010, Volume: 51, Issue:8

    The outcome of patients with multiple myeloma (MM) aged over 75 years remains poor, and the best therapeutic approach has still to be defined. We compared the response, toxicity, and outcome of 34 very elderly patients with MM receiving thalidomide, dexamethasone, and pegylated liposomal doxorubicin (ThaDD) to those of 34 patients matched for age, International Staging System (ISS), and creatinine who received melphalan, prednisone, thalidomide (MPT). ThaDD resulted in a significantly higher response: > or =PR (87.5% vs. 61.5%, p = 0.009) and > or =VGPR (55.5% vs. 29.5%; p = 0.03). No statistical differences were detected in terms of median probability of progression-free survival (PFS) and overall survival (OS) between the two treatments. Patients treated with MPT had more neutropenia, neuropathy, and heart toxicity, whereas thromboembolism resulted more frequently in patients receiving ThaDD. Therapy discontinuation occurred in 9% and 14.5% of patients treated with ThaDD and MPT, respectively. ThaDD can be considered a therapeutic option in very elderly patients with MM since it induces a faster and deeper response than that obtained with MPT, having similar safety profile.

Multiparametric flow cytometry profiling of neoplastic plasma cells in multiple myeloma.
    Cytometry. Part B, Clinical cytometry, 2010, Volume: 78, Issue:5

    The clinical impact of multiparametric flow cytometry (MFC) in multiple myeloma (MM) is still unclear and under evaluation. Further progress relies on multiparametric profiling of the neoplastic plasma cell (PC) compartment to provide an accurate image of the stage of differentiation. The primary aim of this study was to perform global analysis of CD expression on the PC compartment and subsequently to evaluate the prognostic impact. Secondary aims were to study the diagnostic and predictive impact.. The design included a retrospective analysis of MFC data generated from diagnostic bone marrow (BM) samples of 109 Nordic patients included in clinical trials within NMSG. Whole marrow were analyzed by MFC for identification of end-stage CD45(-) /CD38(++) neoplastic PC and registered the relative numbers of events and mean fluorescence intensity (MFI) staining for CD19, CD20, CD27, CD28, CD38, CD44, CD45, CD56, and isotypes for cluster analysis.. The median MFC-PC number was 15%, and the median light microscopy (LM)-PC number was 35%. However, the numbers were significant correlated and the prognostic value with an increased relative risk (95% CI) of 3.1 (1.7-5.5) and 2.9 (1.4-6.2), P < 0.0003 and P < 0.004 of MFC-PC and LM-PC counts, respectively. Unsupervised clustering based on global MFI assessment on PC revealed two clusters based on CD expression profiling. Cluster I with high intensity for CD56, CD38, CD45, right-angle light-scatter signal (SSC), forward-angle light-scatter signal (FSC), and low for CD28, CD19, and a Cluster II, with low intensity of CD56, CD38, CD45, SSC, FSC, and high for CD28, CD19 with a median survival of 39 months and 19 months, respectively (P = 0.02).. The MFC analysis of MM BM samples produces diagnostic, prognostic, and predictive information useful in clinical practice, which will be prospectively validated within the European Myeloma Network (EMN). © 2010 International Clinical Cytometry Society.

Population pharmacokinetics of melphalan in patients with multiple myeloma undergoing high dose therapy.
    British journal of clinical pharmacology, 2010, Volume: 69, Issue:5

    To i) investigate the pharmacokinetics of total and unbound plasma melphalan using a population approach, ii) identify clinical factors that affect melphalan disposition and iii) evaluate the role of melphalan exposure in melphalan-related toxicity and disease response.. Population pharmacokinetic modelling (using NONMEM) was performed with total and unbound concentration-time data from 100 patients (36-73 years) who had received a median 192 mg m(-2) melphalan dose. Model derived estimates of total and unbound melphalan exposure (AUC) in patients with serious melphalan toxicity and those who had a good disease response (>or=90% decrease in paraprotein concentrations) were compared using the Mann-Whitney test.. A two compartment model generated population mean estimates for total and unbound melphalan clearance (CL) of 27.8 and 128 l h(-1), respectively. Estimated creatinine clearance, fat free mass and haematocrit were important determinants of total and unbound CL, reducing the inter-individual variability in total CL from 34% to 27% and in unbound CL from 42% to 30%. Total AUC (range 4.9-24.4 mg l(-1) h) and unbound AUC (range 1.0-6.5 mg l(-1) h) were significantly higher in patients who had oral mucositis (>or=grade 3) and long hospital admissions (P < 0.01). Patients who responded well had significantly higher unbound AUC (median 3.2 vs. 2.8 mg l(-1) h, P < 0.05) when assessed from diagnosis to post-melphalan and higher total AUC (median 21.3 vs. 13.4 mg l(-1) h, P= 0.06), when assessed from pre- to post-melphalan.. Creatinine clearance, fat free mass and haematocrit influence total and unbound melphalan plasma clearance. Melphalan exposure is related to melphalan toxicity while the association with efficacy shows promising trends that will be studied further.

Bortezomib plus dexamethasone induction improves outcome of patients with t(4;14) myeloma but not outcome of patients with del(17p).
    Journal of clinical oncology : official journal of the American Society of Clinical Oncology, 2010, Oct-20, Volume: 28, Issue:30

    Cytogenetics is an important prognostic parameter in multiple myeloma (MM). Patients presenting with either t(4;14) or del(17p) are known to have a short event-free survival (EFS) and overall survival (OS). Some preliminary data suggest that bortezomib is able to overcome these prognostic parameters.. A series of 507 patients with newly diagnosed MM who received four cycles of bortezomib-dexamethasone induction therapy before high-dose melphalan were analyzed for both t(4;14) and del(17p).. We found that both t(4;14) and del(17p) remain prognostic parameters, even in the context of bortezomib treatment. However, it is important to note that bortezomib significantly improves the prognosis (in terms of both EFS and OS) of patients with t(4;14), compared with patients treated with vincristine, doxorubicin, and dexamethasone induction therapy. In contrast, no improvement was observed for del(17p) patients.. Short-term bortezomib induction improves outcome of patients with t(4;14) but not the outcome of patients with del(17p). However, both abnormalities remain prognostic factors predicting both EFS and OS despite bortezomib induction.

A case of aggressive myeloma recognized shortly after the remission following high-dose chemotherapy with autologous peripheral blood stem cell transplantation.
    International journal of hematology, 2010, Volume: 92, Issue:3

    A 45-year-old woman was referred to our hospital with acute renal failure and pyrexia. In August 2005, the patient was diagnosed with IgA-λ type multiple myeloma with chromosome 13 deletion, and received three cycles of vinclistine, adriamycin and dexamethasone followed by high-dose melphalan-based autologous peripheral stem cell transplantation: this resulted in remission 2 months before admission to our hospital. Serum IgA concentration was within the normal limit, but an excess of myeloma cells in bone marrow was confirmed. Immunoelectrophoresis revealed BJP-λ production with no IgA-λ. The patient received several courses of chemotherapy with mechanical ventilation and regular hemodialysis. The progression of the illness was rapid: multiple organ failure promptly developed and the patient died 2 months after admission. Autopsy revealed deposition of light chain λ protein in multiple organs. We report this unusual case of aggressive myeloma recognized shortly after successful autologous transplantation.

High early mortality rate in elderly patients with multiple myeloma receiving a vincristine-doxorubicin-dexamethasone regimen.
    American journal of hematology, 2010, Volume: 85, Issue:10

    Treatment-related mortality (TRM) is not uncommon in patients after the first course of vincristine-doxorubicin-dexamethasone (VAD) chemotherapy,but quite rare after melphalan-prednisolone (MP). This motivated us to compare the rates of TRM after the first course of VAD with those after the first course of MP. We retrospectively assessed survival and TRM in 179 patients treated for multiple myeloma with either MP or VAD. Survival was similar in two groups (P 50.463 in log-rank test). However, TRM was significantly higher inpatients after the first course of VAD (11 in 100 patients, 11.0%) than that after the first course of MP (1 in 79, 1.3%; P 5 0.010). Poor performance status (P 5 0.004) and advanced age (P 5 0.009) before treatment were independent significant factors associated with TRM after the first course of induction therapy. Pyogenic infection was the major cause of TRM after VAD (9 in 11, 81.8%). We concluded that VAD should be cautiously used as induction therapy in multiple myeloma patients, especially in elderly and/or those with poor performance status.

    Cancer is the consequence of sequential acquisition of mutations within somatic cells. Mutations alter the relative reproductive fitness of cells, enabling the population to evolve in time as a consequence of selection. Cancer therapy itself can select for or against specific subclones. Given the large population of tumor cells, subclones inevitably emerge and their fate will depend on the evolutionary dynamics that define the interactions between such clones. Using a combination of in vitro studies and mathematical modeling, we describe the dynamic behavior of two cell lines isolated from the same patient at different time points of disease progression and show how the two clones relate to one another. We provide evidence that the two clones coexisted at the time of initial presentation. The dominant clone presented with biopsy proven cardiac AL amyloidosis. Initial therapy selected for the second clone that expanded leading to a change in the diagnosis to multiple myeloma. The evolutionary dynamics relating the two cell lines are discussed and a hypothesis is generated in regard to the mechanism of one of the phenotypic characteristics that is shared by these two cell lines.

Resolution of mesangial light chain deposits 3 years after high-dose melphalan with autologous peripheral blood stem cell transplantation.
    Clinical nephrology, 2010, Volume: 74, Issue:5

    A 52-year-old woman was admitted to our hospital for treatment of nephrotic syndrome. Funduscopic findings showed fundal hemorrhage and soft exudates, and serologic analysis showed a monoclonal serum component that was identified as Bence Jones protein-k type. A bone marrow biopsy showed diffuse proliferation of atypical plasma cells, while a renal biopsy showed diffuse and nodular mesangial proliferation. Immunohistochemical staining confirmed the presence of k chains along the glomerular basement membrane and in mesangial areas. The patient was diagnosed as multiple myeloma (Bence Jones k type) with light chain deposition disease (LCDD). After high-dose melphalan and autologous peripheral blood stem cell transplantation (PBSCT), the multiple myeloma and nephrotic syndrome were in complete remission; her renal function was improved, but a renal biopsy performed 6 months after PBSCT showed the persistence of diffuse and nodular lesions. By contrast, a renal biopsy performed 3 years later showed complete resolution of the diffuse and nodular mesangial proliferation.

Feasibility of second hematopoietic stem cell transplantation using reduced-intensity conditioning with fludarabine and melphalan after a failed autologous hematopoietic stem cell transplantation.
    Transplantation proceedings, 2010, Volume: 42, Issue:9

    This study was performed to determine the feasibility of second hematopoietic stem cell transplantation (HSCT) using reduced-intensity conditioning (RIC) with fludarabine and melphalan in patients with relapsed hematologic malignancies after a prior autologous HSCT. Twelve patients (multiple myeloma [n = 7], non-Hodgkin lymphoma [n = 3], and acute myeloid leukemia [n = 2] received allogeneic HSCT using RIC with fludarabine (25 mg/m(2) for 5 days) and melphalan (140 mg/m(2) for 1 day) after a failed autologous HSCT. The graft-versus-host disease (GVHD) prophylaxis consisted of cyclosporine plus a minidose of methotrexate. All patients achieved a neutrophil and platelet engraftment in a median 13.5 days and 17.5 days, respectively. The transplant-related mortality was 2 patients (16.7%). Grade II-IV acute GVHD and chronic extensive GVHD were noted in 4 (33.3%) and 1 patient (11.1%), respectively. Over a median follow-up duration of 376 days, 5 patients were alive without evidence of disease. The estimated nonrelapse mortality at 1 year was 28.4%. The estimated overall survival rate at 1 year was 58.3%, and the estimated event-free survival rate at 1 year was 41.7%. Allogeneic HSCT using RIC with fludarabine and melphalan appears to be feasible for a second HSCT in patients with relapsed hematologic malignancies after a failed autologous HSCT.

Elevated fructosamine concentrations caused by IgA paraproteinemia in two dogs.
    Journal of veterinary science, 2010, Volume: 11, Issue:4

    An 8-year-old male Austrian Pinscher and a 14-year-old male Golden Retriever were presented for evaluation due to unexplainable high fructosamine values despite euglycemia and epistaxis in combination with polydipsia/polyuria, respectively. Blood analysis revealed severe hyperglobulinemia, hypoalbuminemia and markedly elevated fructosamine concentrations in both dogs. Multiple myeloma with IgA-monoclonal gammopathy was diagnosed by serum and urine electrophoresis including immunodetection with an anti-dog IgA antibody and bone marrow aspirations. Diabetes mellitus was excluded by repeated plasma and urine glucose measurements. Fructosamine values were positively correlated with globulin, but negatively correlated with albumin concentrations. These cases suggest that, as in human patients, monoclonal IgA gammopathy should be considered as a possible differential diagnosis for dogs with high fructosamine concentrations.

Febrile mucositis in haematopoietic SCT recipients.
    Bone marrow transplantation, 2009, Volume: 43, Issue:1

    We undertook a retrospective analysis of a cohort of 67 patients with multiple myeloma who had received an autologous haematopoietic SCT (HSCT) following high-dose melphalan to explore the impact of mucositis on the systemic inflammatory response. A homogenous group of 16 patients without a documented infection and a group of 30 patients with bacteraemia were identified for whom complete data on neutropenia, an inflammatory response, infectious complications and mucositis were available. All patients showed a similar course of events with an inflammatory response coinciding with the occurrence of significant mucositis, regardless of the presence or absence of infection. The only differences between the two groups were significantly higher maximum C-reactive protein (CRP) levels and lower citrulline levels for patients with bacteraemia, suggesting a causative role for mucositis in the occurrence of bacteraemia. Statistical analysis showed a significant association over time between citrulline levels, to a lesser extent bacteraemia, but not neutropenia, and the inflammatory response measured by CRP. These data suggest that the inflammatory response after conditioning for a HSCT is the result of the chemotherapy-induced mucositis and independent of neutropenia. Though primary inflammation appeared due to mucositis, infections resulting from mucosal barrier injury and neutropenia aggravated the inflammatory response.

The Prospective Oral Mucositis Audit: relationship of severe oral mucositis with clinical and medical resource use outcomes in patients receiving high-dose melphalan or BEAM-conditioning chemotherapy and autologous SCT.
    Bone marrow transplantation, 2009, Volume: 43, Issue:2

    The Prospective Oral Mucositis Audit was an observational study in 197 patients with multiple myeloma (MM) or non-Hodgkin's lymphoma (NHL) undergoing, respectively, high-dose melphalan or BEAM chemotherapy and autologous SCT at 25 European centres. We evaluated the relationship between severe oral mucositis (SOM; WHO Oral Toxicity Scale grade 3-4) and local and systemic clinical sequelae and medical resource use. SOM occurred in 44% of patients. The duration of SOM (mean 5.3 days) correlated with time to neutrophil engraftment. The following parameters increased gradiently with maximum grade of oral mucositis: duration of pain score >or=4, opioid use, dysphagia score >or=4, total parenteral nutrition (TPN) use, incidence and/or duration of fever and infection, and duration of antibiotic use. SOM increased the duration of TPN use by 2.7 days (P<0.001), opioids by 4.6 days (P<0.001), and antibiotics by 2.4 days (P=0.045). SOM prolonged hospital stay by 2.3 days (P=0.013) in MM patients, but not in NHL patients (who tended to have a longer hospital stay). In conclusion, this analysis of prospectively collected observational data provides important insight into the scope and impact of SOM in the European transplant setting.

Actual or ideal body weight to calculate CD34+ cell dose in patients undergoing autologous hematopoietic SCT for myeloma?
    Bone marrow transplantation, 2009, Volume: 43, Issue:4

    CD34+ cell dose calculations are usually based on actual body weight (ABW). We have shown that ideal body weight (IBW) may provide a better basis for this in a small population of patients with hematologic malignancies. This was studied further in 514 myeloma autografts. The CD34+ cell doses (10(6)/kg) by IBW and ABW were 1.37-39.36 (median 6.03) and 1.15-29.67 (median 4.84), respectively. IBW-based cell doses correlated slightly better with engraftment than ABW-based doses (higher r(2)): 0.5 x 10(9)/l neutrophils 0.83 versus 0.82, 1.0 x 10(9)/l neutrophils 0.78 versus 0.77, 20 x 10(9)/l platelets 0.54 versus 0.53 and 50 x 10(9)/l platelets 0.57 versus 0.55. When outliers (hematologic recovery in <8 or >16 days) were excluded, the findings were similar: 0.5 x 10(9)/l neutrophils 0.85 versus 0.84, 1.0 x 10(9)/l neutrophils 0.85 versus 0.84, 20 x 10(9)/l platelets 0.86 versus 0.85 and 50 x 10(9)/l platelets 0.85 versus 0.84. CD34+ cell doses based on IBW as well as ABW significantly affected engraftment when analyzed separately as continuous variables. However, when analyzed together, only the dose based on IBW retained significance. We conclude that calculation of CD34+ cell numbers for autotransplantation should be based on IBW.

High-dose chemotherapy with autologous stem cell transplantation for multiple myeloma: what predicts the outcome? Experience from a developing country.
    Bone marrow transplantation, 2009, Volume: 43, Issue:6

    We analyzed the results of 108 patients (78 males and 30 females) with multiple myeloma who underwent autologous stem cell transplantation (ASCT). The median age of patients was 52 years (range, 26-68 years). High-dose melphalan (200 mg/m(2)) was used for conditioning. In all, 66 (61%) patients had evidence of chemo-sensitive disease before transplant. After ASCT 79.6% of patients responded: complete response 36%, very good partial response 29.6%, and partial response 13.9%. Complete response rate was higher for patients with chemo-sensitive disease; 33 of 66 (50.0%) patients achieved complete response compared with 7 of 42 (14.3%) patients with progressive disease, P<0.01. Response rates to ASCT were significantly low for patients with Hb 5.5 mg/l, International Staging System stage III at diagnosis and >12 months interval from diagnosis to transplant. Grade III-IV mucositis was the major regimen-related toxicity. At a median follow-up of 70 months, the median overall survival and event free survival (EFS) were 71 and 42 months, respectively. Estimated overall survival and EFS at 60 months were 54.4+/-0.05% (s.e.) and 49.3+/-0.05% (s.e.), respectively. Survival was significantly better for patients with pre-transplant chemo-sensitive disease and for those who achieved complete response following transplant.

The novel orally bioavailable inhibitor of phosphoinositol-3-kinase and mammalian target of rapamycin, NVP-BEZ235, inhibits growth and proliferation in multiple myeloma.
    Experimental cell research, 2009, Feb-01, Volume: 315, Issue:3

    NVP-BEZ235 is a new inhibitor of phosphoinositol-3-kinase (PI3 kinase) and mammalian target of rapamycin (mTOR) whose efficacy in advanced solid tumours is currently being evaluated in a phase I/II clinical trial. Here we show that NVP-BEZ235 inhibits growth in common myeloma cell lines as well as primary myeloma cells at nanomolar concentrations in a time and dose dependent fashion. Further experiments revealed induction of apoptosis in three of four cell lines. Inhibition of cell growth was mainly due to inhibition of myeloma cell proliferation, as shown by the BrdU assay. Cell cycle analysis revealed induction of cell cycle arrest in the G1 phase, which was due to downregulation of cyclin D1, pRb and cdc25a. NVP-BEZ235 inhibited phosphorylation of protein kinase B (Akt), P70S6k and 4E-BP-1. Furthermore we show that the stimulatory effect of CD40-ligand (CD40L), insulin-like growth factor 1 (IGF-1), interleukin-6 (IL-6) and conditioned medium of HS-5 stromal cells on myeloma cell growth is completely abrogated by NVP-BEZ235. In addition, synergism studies revealed synergistic and additive activity of NVP-BEZ235 together with melphalan, doxorubicin and bortezomib. Taken together, inhibition of PI3 kinase/mTOR by NVP-BEZ235 is highly effective and NVP-BEZ235 represents a potential new candidate for targeted therapy in multiple myeloma.

ATM-ATR-dependent up-regulation of DNAM-1 and NKG2D ligands on multiple myeloma cells by therapeutic agents results in enhanced NK-cell susceptibility and is associated with a senescent phenotype.
    Blood, 2009, Apr-09, Volume: 113, Issue:15

    There is much evidence to support a role for natural killer (NK) cells in controlling the progression of multiple myeloma (MM), a malignancy characterized by an abnormal plasma cell proliferation in the bone marrow (BM). Induction of DNA damage response has been recently shown capable of enhancing NKG2D ligand (NKG2DL) expression, but nothing is known about DNAM-1 ligand (DNAM-1L) regulation. In this study, we show that myeloma cells treated with low doses of therapeutic agents commonly used in the management of patients with MM, such as doxorubicin, melphalan, and bortezomib, up-regulate DNAM-1 and NKG2D ligands. Accordingly, therapeutic drug treatment of MM cells increases NK-cell degranulation, the NKG2D and DNAM-1 receptors being the major triggering molecules. Similar data were also obtained using ex vivo primary plasma cells derived from MM patients. Drug-induced DNAM-1 and NKG2D ligand expression was abolished after treatment with the ATM (ataxia telangiectasia mutated) and ATR (ATM- and RAD3-related) pharmacologic inhibitors caffeine and KU-55933, and was preferentially associated with senescent cells arrested in the G2 phase of the cell cycle. Altogether, our findings have identified a common pathway that can trigger the up-regulation of different NK cell-activating ligands and suggest that NK cells represent an immunosurveillance mechanism toward cells undergoing stress-induced senescent programs.

Development of rapid light-chain deposition disease in hepatic arteries with severe ischemic cholangitis in a multiple myeloma patient treated with melphalan, prednisone and lenalidomide.
    International journal of hematology, 2009, Volume: 89, Issue:1

    Light-chain deposition disease (LCDD) is a multisystemic disorder associated with plasma cell dyscrasias and multiple myeloma. It is histologically characterized by the deposition of a homogeneous, in electron microscopy granular, slightly eosinophilic material showing positivity usually for kappa light chains. In contrast to AL-amyloidosis, the material is negative for Congo red. LCDD mainly involves the kidneys as the predominant organ manifestation resulting in a nephrotic syndrome. However, involvement of other tissues such as liver and heart have been described. Here we report a case of severe ischemic cholangitis in a patient with multiple myeloma receiving chemotherapy with melphalan, prednisone, and lenalidomide. Histopathological analysis revealed LCDD of the hepatic arteries as the underlying cause. This is to our knowledge the first case of LCDD of terminal liver arteries as a cause of intrahepatic ischemic cholangitis.

Changes in quality-of-life and psychosocial adjustment among multiple myeloma patients treated with high-dose melphalan and autologous stem cell transplantation.
    Biology of blood and marrow transplantation : journal of the American Society for Blood and Marrow Transplantation, 2009, Volume: 15, Issue:1

    High-dose melphalan and autologous hematopoietic stem cell transplantation (HSCT) is a standard treatment for myeloma, but very little is known about the psychosocial or quality-of-life difficulties that these patients encounter during treatment. Data regarding older patients is particularly scarce. Using a prospective design, this investigation evaluated 94 patients at stem cell collection and again after high-dose therapy and transplantation. Outcomes included quality-of-life (FACT-BMT) and psychosocial adjustment (ie, Brief Symptom Inventory, Impact of Events Scale, and Satisfaction with Life Scale). Findings were compared with age- and sex-adjusted population norms and with transplantation patient norms. At stem cell collection, physical deficits were common, with most patients scoring 1 standard deviation below population norms for physical well-being (70.2%) and functional well-being (57.5%), and many reporting at least moderate fatigue (94.7%) and pain (39.4%). Clinically meaningful levels of anxiety (39.4%), depression (40.4%), and cancer-related distress (37.0%) were evident in a notable proportion of patients. After transplantation, there was a worsening of transplant-related concerns (P < .05), depression (P < .05), and life-satisfaction (P < .001); however, pain improved (P < .01), and social functioning was well preserved. Overall, the declines in functioning after transplantation were less pronounced than anticipated. Older patients were not more compromised than younger ones; in multivariate analyses, they reported better overall quality of life (P < .01) and less depression (P < .05) before transplantation. Our findings emphasize the importance of early screening and intervention.

The peptide-semicarbazone S-2209, a representative of a new class of proteasome inhibitors, induces apoptosis and cell growth arrest in multiple myeloma cells.
    British journal of haematology, 2009, Volume: 144, Issue:6

    Bortezomib is the first approved member of a new class of anti-myeloma agents, the proteasome inhibitors. Further proteasome inhibitors are needed to optimise this promising treatment option. S-2209 [1-[1-{1-[(2,4-Dioxo-imidazolidin-1-ylimino)-methyl]-2-phenyl-ethylcarbamoyl}-2-(1H-indol-3-yl)-ethylcarbamoyl]-2-(1H-indol)] inhibits the chymotryptic activity of the human 20S proteasome (half maximal effective concentration, IC(50) approximately 220 nmol/l) which was determined by a proteasome inhibition assay. A nuclear factor kappaB inhibition assay revealed a half maximal effective concentration (EC(50)) of 0.9 micromol/l. The WST-1 growth assay showed inhibition of cell growth of all tested multiple myeloma (MM) cell lines with an IC(50) between 100 nmol/l and 600 nmol/l. Strong induction of apoptosis was seen in MM cells at nanomolar concentrations (IC(50) approximately 300 nm) as well as in primary myeloma cells. No induction of apoptosis was detected in peripheral blood mononuclear cells from healthy humans. Upregulation of p53, activation of JNK protein, and downregulation of Mcl-1 was revealed. Despite the administration of 15 mg S-2209/kg/d in wistar rats, no toxicity with respect to body weight, hepatic enzymes, creatinine or haemoglobin was seen. Proteasome inhibition in white blood cells isolated from the treated rats was higher in the S-2209 treated animals in comparison with the control animals treated with 0.1 mg/kg/d bortezomib. S-2209 is active in myeloma cells and shows a favourable toxicity profile in first in-vivo studies. S-2209 is a promising agent for further clinical development.

Self-reported experience of mucositis in cancer patients who underwent conditioning regimen and stem cell transplantation.
    Supportive care in cancer : official journal of the Multinational Association of Supportive Care in Cancer, 2009, Volume: 17, Issue:10

    This study was done to evaluate the frequency and severity of mucositis in the early period of stem cell transplantation (SCT) and the relation of conditioning regimens with mucositis.. Patients with hematologic or solid tumors who underwent conditioning regimen were asked to score mucositis severity daily from the first day to the tenth day of reinfusion. Patient-reported scoring was performed according to a five-grade scale (0: no symptom; 1: mild; 2: moderate; 3: severe; 4: very severe). Total mucositis score (TMS) was defined as the addition of daily mucositis scores for 10 days. A total of 68 SCT (58 autologous and 10 allogeneic) patients, 48 men (71%) and 20 women (29%) were included to the study. Median age of patients was 32.5 (range 15-78) years. The most frequent three diagnosis were non-Hodgkin's lymphoma (37%, n = 25), Hodgkin's lymphoma (12%, n = 8), and multiple myeloma (12%, n = 8). BEAM (n = 27), ICE (n = 17), melphelan 200 mg/m(2) (M200)(n = 8), and TBI+C (total body irradiation + cyclophosphamide) (n = 16) were used as conditioning regimens.. All of the patients experienced mucositis at any grade. TMS in the sixth day was higher than TMS in the first day (p < 0.05). TMS was not related to the diagnosis or gender (p > 0.05). TMS at ICE regimen in the first 5 days after transplantation was more severe than BEAM regimen. TMS at TBI+C regimen was higher than TMS at BEAM regimen from day 4 to day 10 (p < 0.05). The mean percentages of patients who scored severe or very severe mucositis in 10 days was 7.4% in BEAM, 8.9% in ICE, 12.5% in M200, and 31.2% in TBI+C groups.. Patients experience mucositis frequently following conditioning regimen and SCT. The necessity and the timing of prophylaxis for mucositis change due to the type of conditioning regimens.

Reduction of serum IGF-I levels in patients affected with Monoclonal Gammopathies of undetermined significance or Multiple Myeloma. Comparison with bFGF, VEGF and K-ras gene mutation.
    Journal of experimental & clinical cancer research : CR, 2009, Mar-10, Volume: 28

    Serum levels of IGF-I in patients affected with multiple myeloma (MM) have been scarcely studied. The present study is aimed to explore this point comparing 55 healthy subjects, 71 monoclonal gammopaties of uncertain significance (MGUS) and 77 overt MM patients. In the same subjects, basic FGF and VEGF, have been detected. All three mediators were analyzed in function of K-ras mutation and melphalan response. Concerning IGF-I, two representative monitoring examples have also been added.. Cytokine determinations were performed by commercially available ELISA kits, while K12-ras mutation was investigated on genomic DNA isolated from bone marrow cell specimens by RFLP-PCR assay.. Significant reductions of IGF-I levels were observed in MGUS and MM as compared with healthy controls. In addition, MM subjects showed significantly decreased serum IGF-I levels than MGUS. Conversely, increasing levels were observed for bFGF and VEGF, molecules significantly correlated. A multivariate analysis corrected for age and gender confirmed the significant difference only for IGF-I values (P = 0.01). K12-ras mutation was significantly associated with malignancy, response to therapy and with significantly increased serum bFGF levels.. IGF-I reduction in the transition: Controls-->MGUS-->MM and changes observed over time suggest that IGF-I should be furtherly studied in future clinical trials as a possible monitoring marker for MM.

A simplified method for stem cell autografting in multiple myeloma: a single institution experience.
    Bone marrow transplantation, 2009, Volume: 44, Issue:11

    In a 14-year period in a single institution 31 autografts were performed in 26 patients with multiple myeloma (MM), using a simplified and affordable autografting procedure: conducting the grafts on an outpatient basis and avoiding stem cell freezing. Autografts were started on an outpatient basis in all instances, but four patients were admitted to the hospital. Median time to achieve more than 0.5 x 10(9)/l granulocytes was 27 days, whereas median time to recover above 20 x 10(9)/l plts was 37 days. CR was achieved in 19 cases and a very good partial response in 6 cases. The 100-day mortality was 9.6%. The overall median post-transplant survival has not been reached, being above 76 months, whereas the 76-month survival is 80%. The median cost of each procedure was US$ 15 000. Survival results were substantially better than those of historical control in a group of patients treated in the same institution with melphalan/prednisone. It is concluded that high-dose therapy rescued with a simplified autologous stem cell graft is a valid, useful and affordable therapeutic option for patients with MM, even with economical restraints.

Induction therapy in a multiple myeloma mouse model using a combination of AS101 and melphalan, and the activity of AS101 in a tumor microenvironment model.
    Experimental hematology, 2009, Volume: 37, Issue:5

    We previously showed that the organotellurium compound, ammonium trichloro (dioxyethylene-0-0') tellurate (AS101), has antitumoral activity in multiple myeloma (MM) cell lines. Here, we evaluated the antimyeloma activity of AS101 combined with low-dose melphalan, and also examined the activity of AS101 in the myeloma tumor microenvironment.. Isobologram analysis was performed to determine the interactions of AS101 and melphalan as a combination therapy. Growth arrest, apoptosis, and CD81 antigen were detected by flow cytometry. Using the 5T33MM mouse model, we evaluated mouse survival and serum levels of vascular endothelial growth factor (VEGF) and IgG(2b) paraprotein. We established cocultures of MS-5 bone marrow stromal cells and 5T33 MM cells in order to examine AS101 activity in a myeloma microenvironment model.. Combined treatment of AS101 with melphalan in vitro resulted in a synergistic inhibitory effect on growth, G(2)/M phase growth arrest, reduced IgG(2b) secretion, apoptotic cell death, and reduced fibronectin-mediated adhesion of MM cells. AS101 reduced VEGF secretion and protein expression in myeloma and cocultured cells, downregulated production of the matrix metalloproteinases (MMPs), MMP-9 and MMP-2, and also inhibited growth of the treated myeloma coculture. Combined treatment using AS101 and low dose of melphalan in vivo resulted in modest survival improvement of myeloma-bearing mice and in reduced IgG(2b) and VEGF serum levels.. AS101 in combination with a subtherapeutic dose of melphalan had increased beneficial effect relative to each agent alone in a mouse MM model. In addition, AS101 might be useful for targeting interactions between myeloma cells and the bone marrow microenvironment.

Hematology: Bortezomib in newly diagnosed multiple myeloma.
    Nature reviews. Clinical oncology, 2009, Volume: 6, Issue:5

    Preclinical studies have shown that new agents such as bortezomib not only demonstrate anti-multiple-myeloma activity as single agents but also enhance the efficacy of both chemotherapy and steroids. A randomized trial has established that bortezomib not only improves response rates but also prolongs the lives of patients with multiple myeloma who are not candidates for high-dose chemotherapy.

Influx and efflux transport as determinants of melphalan cytotoxicity: Resistance to melphalan in MDR1 overexpressing tumor cell lines.
    Biochemical pharmacology, 2009, Jul-01, Volume: 78, Issue:1

    There is a considerable variation in efficacy of melphalan therapy in multiple myeloma (MM) and other hematopoietic tumors. We hypothesized that this may be due to variations in the expression of influx and efflux transporters of melphalan. We measured the expression of the influx transporters LAT1, LAT2, and TAT1 and the efflux transporters MDR1, MRP1 and BCRP by quantitative RT-PCR and related their expression to the intracellular accumulation and cytotoxicity of melphalan in 7 MM and 21 non-MM hematopoietic tumor cell lines. Variation in the intracellular accumulation accounted for nearly half of the variation in the cytotoxicity of melphalan in MM cell lines (r(2)=0.47, P=0.04). High expression of the efflux transporter MDR1 was associated with low intracellular accumulation and low cytotoxicity of melphalan (r(2)=0.56, P=0.03 and r(2)=0.62, P=0.02, respectively). The effect was reversed by the MDR1 inhibitor cyclosporine. In addition, the MDR1 overexpressing HL-60 cell line showed 10-fold higher resistance to melphalan than the non-MDR1 expressing one. Again, the resistance was reversed by cyclosporine and by MDR1-specific shRNA. LAT1 was the major influx transporter in tumor cell lines with 4000-fold higher expression than LAT2. Down-regulation of LAT1 by siRNA reduced the melphalan uptake by 58% and toxicity by 3.5-fold, but natural variation in expression between the tumor cell lines was not associated with accumulation or cytotoxicity of melphalan. In conclusion, tumor-specific variations in the expression of the efflux transporter MDR1, but not of the influx transporter LAT1, affect the intracellular accumulation of melphalan and thus determine its cytotoxicity.

Impact of chromosome 13 deletion and plasma cell load on long-term survival of patients with multiple myeloma undergoing autologous transplantation.
    Oncology reports, 2009, Volume: 22, Issue:1

    High-dose therapy (HDT) followed by autologous stem cell transplantation (ASCT) is the most common treatment for patients under 65 years of age with multiple myeloma (MM). In this study, we present a retrospective analysis of the prognostic impact of different factors in patients who have received this treatment as first line therapy in our centre. Abnormalities in chromosome 13 were identified by fluorescence in situ hybridization at the time of diagnosis. The median overall survival (OS) and progression-free survival (PFS) from transplantation time in the whole group of 193 patients were 90 and 48 months respectively. The median follow-up was 65 months (range: 6-186 months). The complete remission (CR) rate in patients with and without del(13) was 31 and 40% respectively whereas the median OS in patients with del(13) was 58 months but not reached in patients without del(13) (p=0.006). The PFS was 26 months in patients with del(13) and 84 months in those without del(13) (p=0.001). The transplantation related mortality was 2.5% both in the absence and presence of del(13). Patients who achieved CR following ASCT had longer OS and PFS when compared to those who only achieved partial remission. Thus, this study confirms the role of del(13) as a marker of poor prognosis. Multivariate analysis showed that the existence of del(13) was the only single independent factor effecting survival (p=0.001). In patients without del(13), the prognostic impact was even stronger when combined with the plasma cell load in the bone marrow (p=0.020), whereas the plasma cell load had no effect on survival of patients with del(13). Overall, the absence of del(13) in combination with low plasma cell infiltration at diagnosis predicts the best survival.

    Five years ago (in September, 2003), the activity of the 5th Haemopoietic Stem Cell Transplantation Centre of Hungary has begun. This centre has been registered as No 648. by the European Group for Blood and Marrow Transplantation-Centres.. To supply the needs of stem cell transplantation regions in north-east Hungary and to develop an active co-operation with the Hungarian and international centres.. Transplantations were made according to international criteria.. 150 autologous stem cell transplantations has been performed so far, including 74 patients with myeloma multiplex, 43 patients with non-Hodgkin lymphoma, 27 patients with Hodgkin's disease, 4 patients with autoimmune disease, and one patient with leiomyosarcoma. The survival rates were similar to the previous Hungarian and international data. The centre played a role in other activities using stem cell therapy at the University of Debrecen (dendritic cell vaccine program, stem cell therapy in myocardial infarction, stem cell therapy in peripheral arterial- and autoimmune diseases). This centre performed the largest quantity of the conditioning protocol Zevalin, Bischloronitrosourea, Etoposide, cytosine-Arabinoside, Melphalan in non-Hodgkin lymphoma in Hungary; ten patients were treated with this protocol.

Hypercytokinemia-induced metabolic encephalopathy in a multiple myeloma patient on hemodialysis undergoing autologous stem cell transplantation: clinical response after plasma exchange.
    Transplant immunology, 2009, Volume: 21, Issue:4

    We report here a 50-years old female with multiple myeloma-associated chronic renal failure who underwent high-dose chemotherapy supported by autologous hematopoietic stem cell transplantation. She developed progressive encephalopathy on day 5 progressing to coma despite hemodialysis and no obvious organ failure. She finally recovered after a single 1-liter plasma exchange. The final diagnosis was metabolic encephalopathy due to hypercytokinemia, particularly high serum TNF levels. We discuss here the pathogenesis and raise an alert for monitoring cytokine levels in patients with renal failure undergoing high-dose chemotherapy.

Thalidomide: new indication. For elderly myeloma patients: some improvement in first-line treatment.
    Prescrire international, 2009, Volume: 18, Issue:100

    (1) First-line treatment with the melphalan-prednisone combination increases median overall survival time by at least 3 years in half of myeloma patients over 65 years of age; (2) Thalidomide, an immunodepressant, is now approved in the European Union as an adjunct to this treatment in elderly myeloma patients; (3) Clinical evaluation is based on 5 trials. One unblinded controlled trial included 447 patients. The addition of thalidomide to the melphalan-prednisone combination increased survival time by at least 1.5 years in half of the patients (median survival time: 51.6 months versus 33.2 months). Another trial in 255 patients that was published in detail showed an increase in progression-free survival, but did not show an overall survival advantage, after more than 3 years of follow-up. Three similar trials have been reported as conference abstracts. One trial showed a survival advantage of 1.5 years, but the other two did not. These 3 trials also showed an increase in progression-free survival; (4) Thalidomide has frequent and sometimes severe adverse effects, including neuropathy, venous thrombosis and pulmonary embolism, cutaneous disorders and bradycardia; (5) Thalidomide is highly teratogenic. As it enters semen, men who have partners of child-bearing age must use very effective methods of birth control; (6) In practice, provided treatment is closely monitored, thalidomide can be added to the melphalan-prednisone combination as first-line treatment for myeloma patients over 65 years of age.

Detection of renal impairment as one specific comorbidity factor in multiple myeloma: multicenter study in 198 consecutive patients.
    European journal of haematology, 2009, Dec-01, Volume: 83, Issue:6

    Comorbidity factors have been reported in cancer patients to predict progression free survival (PFS) and overall survival (OS). Renal impairment (RI) is postulated as one negative prognostic factor in multiple myeloma (MM). The study aim was to detect the best way to define RI and the impact of different RI stages on MM outcome.. In this multicenter analysis, we determined RI [serum creatinine, estimated glomerular filtration rate (eGFR) by modification of diet in renal disease (MDRD) and Cockcroft-Gault] and other prognostic factors in 198 MM patients to ascertain their value on PFS and OS.. Median serum creatinine was 0.9 mg/dL in all patients, whereas the eGFR - being decreased with a median of 80 mL/min/1.73 m(2)- allowed to detect early stages of RI. Via univariate analysis, we observed increasing hazard ratios (HRs) for impaired OS with deteriorating eGFR: with eGFR(MDRD)<90 and <30, HRs were 1.3 and 2.9, respectively. Multivariate analysis determined RI with eGFR<30 and <50 as well as age >59 yr as most important variables for OS. By incorporating eGFR<30 as the most relevant factor determined via multivariate analysis and beta(2)-microglobulin (beta(2)-MG) in a novel MM-risk score, we identified patients with significantly differing OS: median survival with 0, 1 or 2 risk factors were 71, 48, and 24 months, respectively.. These findings demonstrate that RI is frequent in MM, best detected via eGFR determination and an important prognostic factor. eGFR in combination with beta(2)-MG allows definitive risk stratification with largely differing survival in MM.

Inhibition of hypoxia-inducible factor-1 function enhances the sensitivity of multiple myeloma cells to melphalan.
    Molecular cancer therapeutics, 2009, Volume: 8, Issue:8

    Abnormal activation of hypoxia-inducible factor-1 (HIF-1), one of the most important transcription factors for the adaptation of cells to hypoxia, is frequently observed in numerous types of solid tumors. Dysregulation of HIF-1 induces tumor angiogenesis and enhances the expression of anti-apoptotic proteins and glycolysis-associated enzymes in cancer cells, which in turn leads to the promotion of tumor growth. In the present study, we examined the pathophysiologic role of HIF-1 in multiple myeloma. Furthermore, we explored the possibility that HIF-1 may be a molecular target for myeloma therapy. We identified constitutive expression of the hypoxia-inducible factor-1 alpha (HIF-1alpha)-subunit in established myeloma cell lines and in primary myeloma cells. Treatment with insulin-like growth factor-1 (IGF-1) significantly increased HIF-1alpha expression through activation of the AKT and mitogen-activated protein kinase signaling pathways. Inhibition of HIF-1 function either by echinomycin, a specific HIF-1 inhibitor, or a siRNA against HIF-1alpha resulted in enhanced sensitivity to melphalan in myeloma cells. This inhibition of HIF-1 also reversed the protective effect of IGF-1 on melphalan-induced apoptosis. Inhibition of HIF-1 drastically reduced both basal and IGF-1-induced expression of survivin, one of the most important anti-apoptotic proteins in myeloma cells. We conclude that HIF-1 inhibition may be an attractive therapeutic strategy for multiple myeloma.

Macrophages are an abundant component of myeloma microenvironment and protect myeloma cells from chemotherapy drug-induced apoptosis.
    Blood, 2009, Oct-22, Volume: 114, Issue:17

    Multiple myeloma remains an incurable disease. One of the major problems is that myeloma cells develop drug resistance on interaction with bone marrow stromal cells. In this study, we examined the effects of macrophages (Mvarphis), a type of stromal cells, on myeloma cell survival and response to chemotherapy. We showed that Mvarphi, in particular tumor-associated Mvarphi, is a protector of myeloma cells. The protective effect was dependent on direct contact between Mvarphis and myeloma cells. Mvarphis protected both myeloma cell lines and primary myeloma cells from spontaneous and chemotherapy drug-induced apoptosis by attenuating the activation and cleavage of caspase-dependent apoptotic signaling. These findings are clinically relevant because we found that CD68+ Mvarphis heavily infiltrate the bone marrow of patients with myeloma but not the bone marrow of control patients. Thus, our results indicate that Mvarphis may contribute to myeloma cell survival and resistance to chemotherapeutic treatment in vivo.

Short-term thalidomide incorporated into double autologous stem-cell transplantation improves outcomes in comparison with double autotransplantation for multiple myeloma.
    Journal of clinical oncology : official journal of the American Society of Clinical Oncology, 2009, Oct-20, Volume: 27, Issue:30

    To assess potential benefits with thalidomide incorporated into double autologous stem-cell transplantation (ASCT) for younger patients with newly diagnosed multiple myeloma (MM).. One hundred thirty-five patients who received thalidomide from induction until the second ASCT were retrospectively analyzed in comparison with an equal number of pair mates treated with double ASCT not including thalidomide.. On an intention-to-treat basis, the addition of thalidomide to double ASCT effected a significant improvement in the rate (68% v 49%; P = .001) and duration (62% v 33% at 4 years; P < .001) of at least very good partial response (VGPR), time to progression (TTP; 61% v 41% at 4 years; P < .001) and progression-free survival (PFS; 51% v 31% at 4 years; P = .001). A trend was also noted for extended overall survival (OS) among thalidomide-treated patients (69% at 5 years v 53% for the control group), although the difference between the two groups was not statistically significant (P = .07). Benefits with thalidomide in increasing the rate of VGPR or better response, TTP, and PFS were confirmed in a multivariate analysis. Median OS after relapse was 24 months for patients receiving thalidomide added to double ASCT and 25 months for the control group. Overall, 17% of patients discontinued thalidomide, including 8% because of drug-related adverse events.. In comparison with double ASCT, the addition of first-line thalidomide to double ASCT improved clinical outcomes. Short-term thalidomide was generally well tolerated and had no adverse impact on postrelapse survival.

Triple MEL100 therapy in multiple myeloma.
    Transplantation proceedings, 2009, Volume: 41, Issue:9

    Tandem high-dose melphalan therapy with autologous peripheral stem cell support has emerged as the standard of care for patients without prohibitive comorbidities. Mucositis and gastrointestinal side effects are the most common extrahematologic side effects. Two previously published studies presented a triple transplant with a conditioning regimen of melphalan 100 mg/m(2) (MEL100) with peripheral stem cell support every 2 to 5 months for patients with prohibitive comorbidities for high-dose tandem transplantation. We present a novel approach that investigates the triple melphalan 100/m(2) approach on a dose-dense, every-3-weeks schedule in a patient population without significant comorbidities.. Thirteen standard or high-risk patients with stage III multiple myeloma were prospectively treated. This population contained eight patients with immunoglobin G clonality, three immunoglobin A, one nonsecretory, and one light chain isotype. The induction regimens of the 13 patients were heterogenous and included five VAD, three DCIE, two Thal/Dex, two CIE, and one pulse decadron. Patients underwent peripheral blood leukopheresis, and these cells were divided into three equal sets and frozen. The patients were scheduled to receive melphalan at 100 mg/m(2) on days 1, 20, and 41, and then the autologous infusions occurred at days 0, 21, and 42.. All patients were able to receive all three cycles of the MEL100 regimen. Seven patients (54%) received the treatments on the every-3-weeks schedule; three treatments (23%) during the second cycle and six treatments (46%) of the third cycle had to be delayed a median of 6 and 4 days, respectively. Three patients were managed completely in the outpatient setting, and the average total hospital stay for the three transplants was 18 days. Median progression-free survival was 854 days (range 73 to 1571), and the overall survival of this cohort has yet to be reached. No patient had worse than grade II mucositis, and no serious adverse events were recorded.. Our regimen of three consecutive autologous peripheral stem cell transplants with a reduced dose of melphalan at 100 mg/m(2) given every 3 weeks was very well tolerated. The progression-free survival and overall survival are similar and can be compared favorably with the standard tandem myeloma regimens. Our data is intriguing, and further studies with larger numbers need to be performed to confirm these results.

Targeting the Fanconi anemia/BRCA pathway circumvents drug resistance in multiple myeloma.
    Cancer research, 2009, Dec-15, Volume: 69, Issue:24

    The Fanconi anemia/BRCA (FA/BRCA) DNA damage repair pathway plays a pivotal role in the cellular response to replicative stress induced by DNA alkylating agents and greatly influences drug response in cancer treatment. We recently reported that FA/BRCA genes are overexpressed and causative for drug resistance in human melphalan-resistant multiple myeloma cell lines. However, the transcriptional regulation of the FA/BRCA pathway is not understood. In this report, we describe for the first time a novel function of the NF-kappaB subunits, RelB/p50, as transcriptional activators of the FA/BRCA pathway. Specifically, our findings point to constitutive phosphorylation of IkappaB kinase alpha and subsequent alterations in FANCD2 expression and function as underlying events leading to melphalan resistance in repeatedly exposed multiple myeloma cells. Inhibiting NF-kappaB by small interfering RNA, blocking the IkappaB kinase complex with BMS-345541, or using the proteasome inhibitor bortezomib drastically reduced FA/BRCA gene expression and FANCD2 protein expression in myeloma cells, resulting in diminished DNA damage repair and enhanced melphalan sensitivity. Importantly, we also found that bortezomib decreases FA/BRCA gene expression in multiple myeloma patients. These results show for the first time that NF-kappaB transcriptionally regulates the FA/BRCA pathway and provide evidence for targeting Fanconi anemia-mediated DNA repair to enhance chemotherapeutic response and circumvent drug resistance in myeloma patients.

Bortezomib successfully reverses early recurrence of light-chain deposition disease in a renal allograft: a case report.
    Transplantation proceedings, 2009, Volume: 41, Issue:10

    Light-Chain Deposition Disease (LCDD) frequently recurs after renal transplantation, displaying a pernicious course. Herein we have described a 39-year-old Caucasian man with a history of immunoglobulin G-kappa multiple myeloma who failed two chemotherapy regimens, but ultimately responded to the combination of thalidomide, bortezomib, and dexamethasone followed by high-dose melphalan and autologous stem cell transplantation 3 years prior to transplantation, during which time he showed no evidence of persistent or recurrent disease. At 3 days following spousal living related renal transplantation, he displayed a rapid deterioration of renal function requiring dialysis therapy. This episode failed to respond to empiric antirejection therapy including anti-thymocyte globulin, plasmapheresis, and anti-CD20 monoclonal antibody. Increasing evidence suggested recurrence of LCDD, including positive immunofluorescence staining of basement membranes and vessels for kappa light chains as well as free kappa light chains in his urine and serum. Following suspension of sirolimus, he was initiated on and responded to bortezomib (1.3 mg/m(2)) with discontinuation of dialysis within 3 weeks and progressively improving renal function. His maintenance therapy, in addition to six 2-week-long cycles of bortezomib separated by 1-week rest periods, includes cyclosporine (50 mg twice daily), prednisone (10 mg daily), and curcumin (9 g daily). In sum, bortezomib rescue therapy salvaged a spousal renal transplant afflicted with recurrent LCDD.

    (1) New marketing authorizations continue to be granted for treatments of multiple myeloma, and new trials and meta-analyses continue to be published. This review re-examines our previous conclusions based on data published between 2003 and 2008. We again used the standard Prescrire methodology to review the latest data; (2) In patients who are symptomatic but who do not qualify for haematopoietic stem cell transplantation (especially people aged over 65), the results of five comparative trials suggest that adding thalidomide to the melphalan-prednisone combination delays myeloma progression by an additional 5 to 10 months. There is possibly also an increase in overall survival time. This triple combination is therefore a first-line treatment option. There is no firm evidence that replacing thalidomide with bortezomib in this combination provides an advantage; (3) In symptomatic patients aged under 65, two meta-analyses have compared high-dose chemotherapy followed by autologous stem cell transplantation with conventional chemotherapy. Unlike early trials, these meta-analyses showed no overall survival benefit but only a delay in myeloma progression. Initial treatment with two successive transplantation procedures has a negative risk-benefit balance. (4) The optimal chemotherapy regimen prior to autologous stem cell transplantation is controversial. It is unclear which combination (vincristine + doxorubicin + dexamethasone, cyclophosphamide + dexamethasone, cyclophosphamide + dexamethasone, or bortezomib + dexamethasone, etc.) has a better risk-benefit balance in terms of survival and quality of life; (5) According to a meta-analysis of three clinical trials, thalidomide maintenance therapy appears to improve overall survival after Autologous stem cell transplantation; (6) Despite their inadequate evaluation, lenalidomide and pegylated liposomal doxorubicin are licensed for use in patients who relapse or who are refractory to initial treatment. In view of their major adverse effects, we consider that these drugs should only be used in clinical trials.

Superiority of magnetic resonance imaging over conventional radiographs in multiple myeloma.
    Anticancer research, 2009, Volume: 29, Issue:11

    Bone lesions in multiple myeloma (MM) are screened with radiological skeletal survey (RSS) due to its widespread availability. Although bone lesions can be missed by RSS, more sensitive radiological surveys are not as yet recommended for routine use due to the low availability of the methodology and economical considerations.. We report on a 68-year-old male with IgG kappa stage IIIA MM presenting with skeletal pain, fatigue and osteolytic lesions. Since the patient refrained from more intensive therapy, including autologous stem cell transplantation (auto-SCT), he was treated with vertebral irradiation and included in an institutionally guided study which randomized melphalan, prednisone (MP)-lenalidomide (MPR) to MP alone. Although he initially responded, his bone pain reoccurred after three MP cycles. The repeated RSS showed minor, if any changes. Therefore, an MRI was added which revealed extensive osteolyses and extramedullary disease. Justified by these results it was possible to convince the patient that a more intensive therapy approach, including auto-SCT, local irradiation and thalidomide maintenance, was appropriate.. This case calls for an earlier integration of MRI and/or PET/CT scanning in MM, even if RSS remains unchanged, especially if initial bone disease is substantial and/or MM-related symptoms recur. The time course of information and linked decision-making point towards the future significance of an intensified integration of imaging methodologies in the classification and disease management of MM.

[Treatment of myeloma in the elderly].
    Bulletin du cancer, 2008, May-28, Volume: 95 FMC Onco

    The treatment of elderly patients with multiple myeloma was based for the last forty years on the combination of alkeran plus prednisone. The survival was short. Three new molecules, thalidomide, bortezomib and revlimid are completely changing the way we treat myeloma as well as the prognosis. These new molecules are tested either alone or in combination. The addition of thalidomide to alkeran plus prednisone has increased overall survival of two years. For the first time, major therapeutic improvements are emerging giving rise to better prognosis.

Nuclear organization of PML bodies in leukaemic and multiple myeloma cells.
    Leukemia research, 2008, Volume: 32, Issue:12

    The nuclear arrangement of promyelocytic leukaemia nuclear bodies (PML NBs) was studied in vitro after the cell treatment by clinically used agents such as all-trans retinoic acid (RA) in human leukaemia and cytostatics or gamma radiation in multiple myeloma cells. In addition, the influence of phorbol ester (PMA) on PML NBs formation was analyzed. A reduced number of PML bodies, which led to relocation of PML NBs closer to the nuclear interior, mostly accompanied RA- and PMA-induced differentiation. Centrally located PML NBs were associated with transcriptional protein RNAP II and SC35 regions, which support importance of PML NBs in RNA processing that mostly proceeds within the nuclear interior. Conversely, the quantity of PML NBs was increased after cytostatic treatment, which caused re-distribution of PML NBs closer to the nuclear envelope. Here we showed correlations between the number of PML NBs and average Centre-to-PML distances. Moreover, a number of cells in S phase, especially during differentiation, influenced number of PML NBs. Studying the proteins involved in PML compartment, such as c-MYC, cell-type specific association of c-MYC and the PML NBs was observed in selected leukaemic cells undergoing differentiation, which was accompanied by c-MYC down-regulation.

A unique three-dimensional model for evaluating the impact of therapy on multiple myeloma.
    Blood, 2008, Oct-01, Volume: 112, Issue:7

    Although the in vitro expansion of the multiple myeloma (MM) clone has been unsuccessful, in a novel three-dimensional (3-D) culture model of reconstructed bone marrow (BM, n = 48) and mobilized blood autografts (n = 14) presented here, the entire MM clone proliferates and undergoes up to 17-fold expansion of malignant cells harboring the clonotypic IgH VDJ and characteristic chromosomal rearrangements. In this system, MM clone expands in a reconstructed microenvironment that is ideally suited for testing specificity of anti-MM therapeutics. In the 3-D model, melphalan and bortezomib had distinct targets, with melphalan targeting the hematopoietic, but not stromal com-partment. Bortezomib targeted only CD138(+)CD56(+) MM plasma cells. The localization of nonproliferating cells to the reconstructed endosteum, in contact with N-cadherin-positive stroma, suggested the presence of MM-cancer stem cells. These drug-resistant CD20(+) cells were enriched more than 10-fold by melphalan treatment, exhibited self-renewal, and generated clonotypic B and plasma cell progeny in colony forming unit assays. This is the first molecularly verified demonstration of proliferation in vitro by ex vivo MM cells. The 3-D culture provides a novel biologically relevant preclinical model for evaluating therapeutic vulnerabilities of all compartments of the MM clone, including presumptive drug-resistant MM stem cells.

Cardiac toxicity of high-dose cyclophosphamide and melphalan in patients with multiple myeloma treated with tandem autologous hematopoietic stem cell transplantation.
    International journal of hematology, 2008, Volume: 88, Issue:2

    Tandem autologous hematopoetic stem cell transplantation (HSCT) is an effective treatment in patients with multiple myeloma (MM). Patients receive high-dose cyclophosphamide (CY) followed by two myeloablative dosages of melphalan (MEL). Cardiotoxicity treatment related data are scanty. In 30 patients with MM chemotherapy was followed by high-dose CY (cycle CY), and two autologous tandem HSCT treatments with MEL (cycles MEL I and MEL II). During each 15-day treatment troponin I (TnI), brain natriuretic peptide (BNP) and endothelin-1 (ET-1) were controlled at six time points. All patients underwent conventional and tissue Doppler echocardiography prior to CY therapy (Eho 0), before cycle MEL I (Eho 1), before cycle MEL II (Eho 2), and 3 months after the completion of therapy (Eho 3). None of the patients developed clinical signs of heart failure. The peak TnI concentrations were noted at days 8, 11, and 15 during all three chemotherapy cycles. During all three cycles there was a significant increase in baseline BNP concentrations and BNP levels measured at day 1 after treatment with CY and MEL (CY: P = 0.0001, MEL I: P = 0.001, MEL II: P = 0.001). The highest BNP concentration occurred during CY treatment (0.517 +/- 0.391 microg/L). During cycles MEL I and MEL II we noted the peak BNP concentrations at day 4 following chemotherapy (MEL I 0.376 +/- 0.418 microg/L; MEL II 0.363 +/- 0.379 microg/L). During all three cycles the highest ET-1 levels occurred at day 1 after chemotherapy (CY 1.146 +/- 1.313 ng/L; MEL I 1.054 +/- 2.242 ng/L; MEL II 0.618 +/- 0.539 ng/L). A significant increase in ET-1 concentrations relative to the basal values occurred only in cycle MEL II (P = 0.003). The duration of wave a in the Doppler pulmonary vein flow increased significantly (Eho 0/Eho 1: P = 0.008, Eho 0/Eho 3: P = 0.026). There was a significant decrease in the A/a ratio in flow velocities during chemotherapy (Eho 0/Eho 1: P = 0.002, Eho 0/Eho 3: P < 0.0001). Early diastolic tissue Doppler velocities (Em) decreased significantly during individual cycles of chemotherapy (P = 0.006). A significant post-treatment increase in the incidence of mitral regurgitation was observed (Eho 0/Eho 3: P = 0.003). Treatment of MM patients with tandem autologous HSCT is cardiotoxic. Our patients did not develop clinically overt heart failure or myocardial necrosis. Increased plasma levels of BNP and ET-1 were compatible with transient neurohormonal activation of heart failure.

Impact of additional cytoreduction following autologous SCT in multiple myeloma.
    Bone marrow transplantation, 2008, Volume: 42, Issue:4

    Reported results of high-dose therapy (HDT) reflect the combined effect of initial therapy and HDT. The incremental contribution of HDT is often difficult to analyze with varying degrees of response pre-HDT. Here we analyze results of HDT in patients with measurable disease at transplant, defined as a serum or 24 h urine M protein of >1.0 g per 100 ml and >200 mg per day, respectively. Paraprotein responses were calculated using measurements prior to HDT and the lowest subsequent measurement. A total of 431 patients were studied; 264 (61.3%) transplanted within 1-year of diagnosis. An additional reduction in paraprotein by 50% following HDT was seen in 86% patients; with 129 patients (30%) obtaining a 90% reduction. Patients with at least a 90% reduction had longer time to progression with no overall survival advantage and this was independent of other prognostic factors for decreased risk of progression. This study provides an estimate of the degree of tumor reduction provided by HDT, in addition to that provided by the initial therapy. In this group of patients with measurable disease after initial therapy, HDT therapy leads to complete responses in nearly a quarter of the patients and a 90% reduction in another 7%, an outcome associated with better progression-free survival.

High-dose melphalan and auto-SCT in patients with monoclonal Ig deposition disease.
    Bone marrow transplantation, 2008, Volume: 42, Issue:6

    The treatment of monoclonal Ig deposition disease (MIDD) is controversial and not standardized. We report our experience with high dose melphalan and auto-SCT (HDM/auto-SCT) in seven patients with MIDD associated with underlying Durie-Salmon stage IB multiple myeloma, including five with light chain deposition disease, one with light and heavy chain deposition disease and one with light chain crystal deposition disease. The median age of these patients was 50 years; six of them were male subjects. A monoclonal kappa-light chain was detected by Serum Free Light Chain Assay in all seven. The patients received melphalan 140 mg/m(2) followed by auto-SCT. All patients are alive and six remain in hematologic CR with a median follow up of 23.6 months (7.9-69.8 months). Renal function has improved compared to pre-HDSM/auto-SCT in five patients--two of whom had a renal transplant and became dialysis independent--remained stable in one and worsened in one leading to hemodialysis despite hematologic CR. Our results corroborate previous experience with HDM/auto-SCT in MIDD and argue in favor of kidney transplantation in patients who achieve hematologic CR after HDM/auto-SCT. Although this approach appears effective, multi-center studies are needed to define the optimal treatment for patients with MIDD.

MUC1 oncoprotein promotes growth and survival of human multiple myeloma cells.
    International journal of oncology, 2008, Volume: 33, Issue:1

    The MUC1 oncoprotein is aberrantly expressed in human multiple myeloma cells by mechanisms that are not understood. Moreover, the functional role of MUC1 in multiple myeloma is not known. The present studies demonstrate that the MUC1 gene locus is amplified in multiple myeloma cell lines and in primary cells from patients. The KMS28PE multiple myeloma cell line, which was found to have MUC1 gene amplification, was stably silenced for MUC1 using different siRNAs. Silencing MUC1 was associated with a decrease in nuclear beta-catenin levels, consistent with the function of MUC1 in stabilizing beta-catenin. MUC1 is also known to activate the IKKbeta-->NF-kappaB pathway and KMS28PE cells silenced for MUC1 were found to have downregulation of IKKbeta and IkappaBalpha phosphorylation, and decreased nuclear targeting of NF-kappaB p65. The results also demonstrate that MUC1: i) contributes to KMS28PE cell proliferation, and ii) protects against apoptosis and loss of self-renewal in the response to melphalan and dexamethasone. These findings indicate that MUC1 activates the beta-catenin and NF-kappaB pathways in multiple myeloma cells and contributes to their growth and survival.

Bacteraemia coincides with low citrulline concentrations after high-dose melphalan in autologous HSCT recipients.
    Bone marrow transplantation, 2008, Volume: 42, Issue:5

    Mucosal damage to the intestines induced by myeloablative conditioning for allogeneic PBSC transplant (PBSCT) can be determined by the concentration of citrulline, which is a functional marker of small intestinal enterocytes. Low citrulline concentrations in blood coincide with and are a response to severe mucosal barrier injury. We treated 29 patients with high-dose melphalan 200 mg/m(2) (Mel-200) to prepare for an autologous PBSCT and collected plasma samples from each patient starting before the myeloablative regimen and three times per week thereafter until discharge. The baseline citrulline concentration was 27.6 mM+/-4.0 (mean+/-95% confidence interval; CI), and citrulline concentrations declined rapidly thereafter reaching a nadir averaging 6.7 mM+/-2.7, 12 days after starting Mel-200. Citrulline concentrations, only increased gradually and were still low (12 mM+/-4) at discharge. A total of 20 patients developed fever, which was associated with bacteraemia in 10 cases. Their mean citrulline concentrations were lower at 5.5 mM+/-1.5 than were those of patients without bacteraemia (10.2 mM+/-3.9). Importantly, neither the number of preceding neutropenic days nor the mean C-reactive protein (CRP) concentration at the onset of fever was different between these two groups. In conclusion, citrulline concentrations rapidly decline after Mel-200 reflecting intestinal mucosal barrier injury. Low citrulline, rather than the duration of neutropenia, is associated with bacteraemia indicating the importance of an intact mucosal barrier in neutropenic patients.

Hepatic veno-occlusive disease after tandem autologous stem cell transplantation conditioned by melphalan.
    International journal of hematology, 2008, Volume: 88, Issue:3

    We report the case of a 58-year-old man with multiple myeloma stage III A who received tandem autologous stem cell transplantation after induction by two courses of VAD and three cycles of bortezomib-dexamethasone, due to progression under chemotherapy. The second transplantation was complicated by severe hepatic veno-occlusive disease (HVOD). The patient received defibrotide with total recovery. The occurence of HVOD after conditioning by melphalan is uncommon and the role of bortezomib was questioned.

Autologous stem-cell transplantation in patients with multiple myeloma.
    Prilozi, 2008, Volume: 29, Issue:1

    - Multiple myeloma is a malignant plasma-cell proliferative disorder, the second most common haematologic cancer. Treatment with high-dose therapy (HDT) and single autologous stem cell transplantation (ASCT) is a category I recommendation of the National Comprehensive Cancer Network. Double transplantation can be proposed for patients failing to achieve small a, Cyrillic very good partial response (VGPR) after a first ASCT. Aims - The aim of this study is to analyse the effect of treatment with high-dose chemotherapy and autologous stem-cell support on survival in patients with multiple myeloma, and to compare our results with the results from other transplant centres.. - during a 7-year period we have performed 20 high-dose chemotherapy courses and autologous stem-cell transplantation on 17 patients (3 tandem transplantations) with multiple myeloma. In this trial we retrospectively analysed the epidemiology characteristics of these patients. Female: 9 Male - 8. Median age: 53 years (from 43-64 years).. diagnosis was made according to Salmon and Durie criteria. High-dose regimen consisted of Melphalan doses of 200mg/m2. In tandem transplantations the dose of the second high-dose regimen was 140 mg/m2. The volume of CD34+ cells was approximately 3.8 x 10exp8/Kg.bw. In 3 patients we used phlebothomy as a source of added stem cells. The period from diagnosis to transplantation was 12 months. Of 17 patients 70% are alive, 5 have died (3 renal failure, 1 fatal cerebral bleeding and 1 with multiorgan failure). The disease-free survival was 22 months in our group of patients. Overall survival was 48 months and survival after transplantation was 35 months. The probability of 7 years' overall survival exists in 50% of patients.. Patients treated with high-dose chemotherapy followed by autologous stem-cell support have a better survival and quality of life compared with patients treated with standard chemotherapy.

Erythrophagocytic multiple myeloma in a cat.
    Veterinary clinical pathology, 2008, Volume: 37, Issue:3

    A 7-year-old neutered male domestic shorthair cat was presented to the Veterinary Medical Teaching Hospital at the University of Georgia for further evaluation of a suspected osteolytic lesion of the left 10th rib. Results of a CBC and biochemistry profile revealed mild nonregenerative anemia, hyperproteinemia, hyperglobulinemia, and hypercalcemia. Serum protein electrophoresis was consistent with a monoclonal gammopathy. Marked proteinuria with an increased urine protein to creatinine ratio was found. Cytologic examination of the liver, spleen, and bone marrow revealed numerous plasma cells, many of which were erythrophagocytic. Within the bone marrow, the plasma cells contained phagocytosed metarubricytes in addition to phagocytosed erythrocytes. A diagnosis of erythrophagocytic multiple myeloma was made and treatment with prednisone and melphalan was begun. Four weeks after presentation, the cat was euthanized due to clinical deterioration. A complete necropsy was performed. The distal one-third of the left 10th rib was completely absent. Histologically, there was no evidence for osteolysis or neoplastic cells in the remaining portion of the rib. However, large sheets of plasma cells were found infiltrating the spleen and bone marrow. Moderate erythrophagocytosis by the plasma cells was observed in both organs. The plasma cells, including the erythrophagocytic cells, were positive for CD79alpha by immunohistochemical staining. Erythrophagocytosis by plasma cells as a cause of anemia is uncommon in people with multiple myeloma and is rare in animals. To our knowledge, this is the first report of erythrophagocytic plasma cells in a cat with multiple myeloma.

Clinical evidence for immunomodulation induced by high-dose melphalan and autologous blood stem cell transplantation as cause for complete clinical remission of multiple myeloma-associated cryoglobulin-vasculitis.
    International journal of hematology, 2008, Volume: 88, Issue:4

    We present a case report of a patient with cryoglobulin-vasculitis caused by multiple myeloma in Durie/Salmon stage I refractory to conventional therapy modalities treated with high-dose chemotherapy followed by autologous blood stem cell transplantation. While clinical symptoms of vasculitis disappeared, elevated cryoglobulin levels persisted. Therefore we conclude that the relief of symptoms was caused by an immunomodulation induced by the autologous stem cell transplantation.

Poor outcomes for IgD multiple myeloma patients following high-dose melphalan and autologous stem cell transplantation: a single center experience.
    Journal of Korean medical science, 2008, Volume: 23, Issue:5

    Immunoglobulin (Ig) D multiple myeloma (MM) accounts for 2% of all MM cases and has been reported to be associated with poor prognosis compared with other MM subtypes. The aim of the present study was to compare the effects of high-dose melphalan treatment and autologous stem cell transplantation (ASCT) on the survival of patients with IgD MM and patients with other MM subtypes. Between November 1998 and January 2005, a total of 77 patients with MM who underwent ASCT at the Asan Medical Center were enrolled in this study. High-dose melphalan (total 200 mg/m2) was used as high-dose chemotherapy. The study population was divided into two groups based on MM subtype: those with IgD MM; and those with other MM subtypes. A total of 8 patients with IgD MM were identified, accounting for about 10% of the study population. Thirty-six patients (47%) had IgG MM, 17 patients (22%) had IgA MM, and 16 patients (20%) had free light-chain MM. The two groups were similar in baseline characteristics. The median follow-up was 17 months and the median overall survival (OS) was 39 months. In the IgD MM group, median eventfree survival (EFS) and OS were 6.9 and 12 months, respectively. In the patients with other MM subtypes, median EFS and OS were 11.5 and 55.5 months (p=0.01, p<0.01), respectively. Multivariate analysis of all patients identified IgD subtype (p=0.002) and Southwest Oncology Group (SWOG) stage 2 or greater at the time of ASCT (p=0.01) as adverse prognostic factors for survival. In this small study at a single center in Korea, patients with IgD MM had poorer outcomes after ASCT than did patients with other MM subtypes.

Ectopic cyclin D1 overexpression increases chemosensitivity but not cell proliferation in multiple myeloma.
    International journal of oncology, 2008, Volume: 33, Issue:6

    We established a myeloma cell line (RPMI8226) with cyclin D1 overexpression in which the transfected cyclin D1 gene was stably expressed. D1 transfectants showed down-regulation of cyclin D2. Cell proliferation analysis did not show any differences among RPMI8226, mock control, and D1 transfectants. The number of S-phase cells increased while the number of G0/G1- and G2/M-phase cells decreased in D1 transfectants, which indicates a prolonged S-phase caused by cyclin D1 transfection. A decreased number of G2/M-phase cells was also detected in myeloma cells of patients with translocation t(11;14)(q13;q32). Western blot analysis revealed an increase in the hyperphosphorylated form of retinoblastoma (Rb) protein in D1 transfectants; however, the expression of p53, p16, Bax, Bad, Bcl-2, and Mcl-1 did not significantly change. Treatment with anti-myeloma drugs (melphalan, dexamethasone, bortezomib and immunomodulatory compounds) induced apoptosis earlier in D1 transfectants compared with RPMI8226 and mock control via the activation of both caspase-8 and -9. However, we could not detect a relationship between cyclin D1 expression and the response to treatment with VAD and bortezomib. Therefore, we assume that high sensitivity to anti-myeloma drugs depends on the duration of the S-phase, but a clinical response might depend on the number of myeloma cells with cyclin D1 overexpression.

Bortezomib-induced cutaneous lesions in multiple myeloma patients: a case report.
    Dermatology online journal, 2008, Nov-15, Volume: 14, Issue:11

    Proteasome inhibitors are emerging as a promising class of anti-cancer therapeutic agents. Bortezomib (PS341) is the first proteosome inhibitor with clinical significance. It acts by blocking vital functions of tumoral cells in myeloma, inducing apoptosis. Its toxicity is usually manageable. Gastrointestinal symptoms, peripheral neuropathy, neuropathic pain and thrombocytopenia are described as the most common side effects. We report on a case of cutaneous lesions induced by bortezomib in a patient with relapsed multiple myeloma (MM).

A pivotal role for Mcl-1 in Bortezomib-induced apoptosis.
    Oncogene, 2008, Jan-31, Volume: 27, Issue:6

    Bortezomib is a proteasome inhibitor for the treatment of relapsed/refractory multiple myeloma (MM). Mechanisms of resistance to Bortezomib are undefined. Myeloid cell leukemia-1 (Mcl-1) is an antiapoptotic protein, which protects tumor cells against spontaneous and chemotherapy-induced apoptosis. In MM, specific downregulation of Mcl-1 induces apoptosis. Here, we examined the role of Mcl-1 in Bortezomib- and doxorubicin-induced apoptosis. We demonstrate that Bortezomib, but not doxorubicin, triggers caspase-dependent generation of a 28 kDa Mcl-1-fragment, in several MM cell lines, including MM.1S cells. Conversely, transient transfection of MM.1S cells with a previously reported 28 kDa Mcl-1(128-350) fragment, but not with the Mcl-1(1-127) fragment, induces apoptosis. Therefore, both downregulation of full-length antiapoptotic Mcl-1, as well as Bortezomib-induced generation of Mcl-1(128-350) cleaved protein, contribute to MM cell apoptosis. To verify further these findings, we next compared effects triggered by Bortezomib, doxorubicin and melphalan in Mcl-1(wt/wt) and Mcl-1(Delta/null) murine embryonic fibroblasts (MEFs). Our results show that Bortezomib, but not doxorubicin or melphalan, triggers Mcl-1 cleavage in Mcl-1(wt/wt), but not Mcl-1(Delta/null) MEFs and induces sub-G(1) phase cells; caspase-3 and -9, and PARP cleavage as well as morphological signs of apoptosis. Taken together, these results support an important role of Mcl-1 and a Mcl-1 fragment in Bortezomib-induced cell death in general, and in MM in particular. To prevent relapse of MM in patients treated with Bortezomib, we therefore recommend the combination of Bortezomib with agents that induce MM cell death independent of Mcl-1.

Cytogenetically defined myelodysplasia after melphalan-based autotransplantation for multiple myeloma linked to poor hematopoietic stem-cell mobilization: the Arkansas experience in more than 3,000 patients treated since 1989.
    Blood, 2008, Jan-01, Volume: 111, Issue:1

    Myelodysplastic syndrome (MDS) is a well-recognized complication of chemotherapy for multiple myeloma (MM). Serial bone marrow metaphase examinations were performed for MM restaging in 3,077 patients undergoing high-dose therapy (HDT). MDS-associated cytogenetic abnormalities (MDS-CAs) were observed in 105 of 2,418 patients in whom cytogenetic data were available after HDT. MDS-CAs occurred transiently in 72 patients and on 3 successive occasions (persistent MDS-CAs) in 33 patients, for 10-year estimates of 4% and 2%, respectively; only 21 patients developed overt clinical MDS and 5, acute myeloblastic leukemia (AML). MDS-CA development was linked to lower CD34 yield at collection, longer time interval from MM diagnosis to HDT, older age, and lower platelet recovery after HDT; persistent MDS-CAs were predicted by CD34 yield of less than 3 x 10(6)/kg and need for more than 2 apheresis procedures. Applying a tertile frequency distribution over time to all 105 patients with MDS-CAs, its detection early after HDT was associated with longer time interval from diagnosis and low pre-HDT platelet count (likely resulting from pre-HDT damage), whereas late-onset MDS-CAs were noted among patients treated with Total Therapy 2 and Total Therapy 3 that applied post-HDT consolidation chemotherapy (suggesting possible post-HDT damage). While the risk of MDS-CAs was low and clinical MDS occurred infrequently, monitoring after post-HDT consolidation chemotherapy appears warranted.

Inhibitors of protein kinase C sensitise multiple myeloma cells to common genotoxic drugs.
    European journal of haematology, 2008, Volume: 80, Issue:1

    Despite high dose treatment regimes multiple myeloma (MM) disease is still not curable. Patients become resistant to cytotoxic drugs and die of disease progression. Therefore, besides new cytotoxic compounds drug sensitisers are urgently needed.. The MM cell lines U266, OPM-2, RPMI-8226 and NCI-H929 were incubated with the common anti-myeloma drugs like melphalan together with protein kinase C (PKC) inhibitors. Growth inhibition was measured using the water-soluble tetrazolium salt 4-[3-(4-iodophenyl)-2-(4-nitrophenyl)-2H-5-tetrazolio]-1,3-benzene disulfonate (WST-1 assay), and apoptosis was determined by flow cytometry after staining with fluorescein isothiocyanate-labeled annexin V (annexin-V-FITC) and propidium iodide. Intracellular signalling was shown by western blotting.. In this study we show that the combination of melphalan or doxorubicin with a PKC inhibitor, Gö6976 or enzastaurin, strongly increases cell toxicity. Increase of cytotoxicity is shown to be due to increased induction of apoptosis. Furthermore, we show that the protective effect of human bone marrow stromal cells (hBMSC) is abrogated by the PKC inhibitors. Finally, western blotting experiments revealed that incubation of myeloma cells with cytotoxic drugs like melphalan or doxorubicin leads to increased phosphorylation and therefore degradation of inhibitor of nuclear factor kappa B (IkappaB) and release of nuclear factor kappa B (NFkappaB). In contrast, enzastaurin inhibits phosphorylation of IkappaB.. We conclude that the combination of conventional drugs and PKC inhibitors might be very effective and represents a new strategy in the treatment of MM.

Alkylating agents induce activation of NFkappaB in multiple myeloma cells.
    Leukemia research, 2008, Volume: 32, Issue:7

    Multiple myeloma is still not curable and drug combination strategies are currently being evaluated in order to achieve high remission rates with tolerable toxicity. Bortezomib has been shown to exert inhibitory effects on NFkappaB activity. NFkappaB in turn is known to be activated by cytokines, growth factors and by cellular adhesion to bone marrow stromal cells and represents an important mediator of primary and secondary drug resistance in multiple myeloma that confers to proliferation and survival. In this study we confirm that bortezomib sensitized MM cells to the DNA-damaging drugs melphalan and doxorubicin. Further, we demonstrate that the sole incubation of MM cells with melphalan or doxorubicin leads to a vast activation of NFkappaB activity. Additionally, we show that the co-incubation of bortezomib with melphalan or doxorubicin reduces activation of NFkappaB. These data suggest that the drug-sensitizing effect of bortezomib on MM cells is due to inhibition of melphalan- and doxorubicin-induced activation of NFkappaB activity. This study, therefore, supports the idea of combining a NFkappaB inhibitor with alkylating drugs in the therapy of multiple myeloma.

Amyloidosis and vascular thrombosis.
    Saudi journal of kidney diseases and transplantation : an official publication of the Saudi Center for Organ Transplantation, Saudi Arabia, 2008, Volume: 19, Issue:1

    Amyloidosis is a rare systemic disorder of protein metabolism with progressive extra-cellular deposition of insoluble fibrillary protein, disorganization of tissue architecture, and subsequent organ dysfunction. Primary amyloidosis is the most common form of this disorder, however, it can develop secondary to plasma cell dyscrasias such as multiple myeloma (MM); 10-15% of MM patients may develop amyloidosis of vital organs. Amyloidosis is usually associated with bleeding, but less commonly with thrombosis. We present a 52-year-old Saudi female with amyloidosis secondary to multiple myeloma. She presented with both venous and extensive arterial thrombosis. Although relatively rare, plasma cell dyscrasias such as amyloidosis and multiple myeloma could present with thrombotic rather than hemorrhagic complications.

Symptom burden after autologous stem cell transplantation for multiple myeloma.
    Cancer, 2008, Apr-01, Volume: 112, Issue:7

    Multiple myeloma (MM) is the most common indication for high-dose chemotherapy with autologous stem cell transplantation (ASCT) in the U.S. and can be associated with substantial morbidity. Thorough assessment and understanding of symptoms and risk factors for symptom development after ASCT are logical first steps toward developing strategies aimed at reducing the symptom burden associated with this procedure.. The authors performed a prospective evaluation of symptom burden among 64 patients with myeloma who underwent ASCT. Symptom data were collected using the M. D. Anderson Symptom Inventory (MDASI) at 4 time points: baseline, the day of stem cell infusion (Day 0), nadir of counts, and Day 30. Univariate analysis was performed to correlate pretransplantation variables with post-transplantation symptom burden at these time points.. MDASI scores increased significantly throughout transplantation, with most patients returning to baseline by Day 30 after the procedure. Patients with the highest MDASI scores at baseline had the highest MDASI scores at nadir (P= .02). Patients with prolonged time to transplantation and women had a trend toward higher nadir global symptom severity scores. These groups, as well as patients aged >60 years, had a trend toward higher nadir interference scores.. ASCT for MM was associated with significant but reversible symptom burden during the first 30 days, and the baseline symptom burden was the most important predictor of symptom burden after transplantation. The MDASI was useful as a tool for following the symptom burden associated with ASCT and may be used to evaluate interventions aimed at reducing transplantation-related morbidity in these patients.

Prospective oral mucositis audit: oral mucositis in patients receiving high-dose melphalan or BEAM conditioning chemotherapy--European Blood and Marrow Transplantation Mucositis Advisory Group.
    Journal of clinical oncology : official journal of the American Society of Clinical Oncology, 2008, Mar-20, Volume: 26, Issue:9

    The Prospective Oral Mucositis Audit assessed the incidence, duration, and determinants of severe oral mucositis (OM; WHO oral toxicity scale grades 3 to 4) in patients with multiple myeloma (MM) or non-Hodgkin's lymphoma (NHL) receiving high-dose conditioning chemotherapy before autologous stem-cell transplantation.. Patients with MM (n = 109; mean age, 57 +/- 8 years) or NHL (n = 88; mean age, 50 +/- 13 years) were treated with high-dose melphalan (200 mg/m(2)) or carmustine 300 mg/m(2), etoposide 800 mg/m(2), cytarabine 800 to 1,600 mg/m(2), and melphalan 140 mg/m(2) chemotherapy, respectively, in 25 European centers. OM assessments were made daily until 30 days after transplantation or hospital discharge. High quality of OM assessment was ensured by an intensive training program.. Severe OM occurred in 46% (95% CI, 36% to 56%) of patients with MM and 42% (95% CI, 32% to 53%) of patients with NHL, with a mean duration of 5.3 days (95% CI, 4.4 to 6.1 days) and 5.5 days (95% CI, 4.5 to 6.7 days), respectively. Time from start of conditioning to peak OM score was 12.1 +/- 2.6 and 14.6 +/- 2.4 days. Severe OM risk and/or duration was significantly associated with higher chemotherapy dose per kilogram of body weight and poor performance status, but in contrast with some previous reports, this was not related to age.. Severe OM is more common in the transplantation setting than previously reported, justifying effective preventative and therapeutic measures.

Thromboembolic events with lenalidomide-based therapy for multiple myeloma.
    Cancer, 2008, Apr-01, Volume: 112, Issue:7

    The purpose was to evaluate the incidence and risk factors of thromboembolism associated with lenalidomide therapy in newly diagnosed myeloma.. A pooled analysis was performed of patients with previously untreated multiple myeloma enrolled in clinical trials of lenalidomide-based therapy at the Mayo Clinic, Rochester, Minnesota, and the Italian Myeloma Network, Italy. The incidence of thrombosis, the effect of risk factors such as steroid dose and erythropoietin supplementation, and the effect of prophylaxis were examined.. In all, 125 patients enrolled in 3 clinical trials were identified. Patients were stratified based on the concomitant corticosteroid dose. Fifty-two patients were in the high-dose group (dexamethasone 40 mg, 12 days a month); 73 patients were in the low-dose group (prednisone at any dose; or dexamethasone 40 mg, 4 days a month). A total of 110 patients were initiated on thromboprophylaxis; of these, 104 patients (95%) received aspirin. Ten patients (8%) developed deep vein thrombosis, including 4 who were not receiving any thromboprophylaxis at the time of the event. The rate of thromboembolic events was not different between patients who received concomitant erythropoietin therapy and those who did not, 4.8% and 8.6%, respectively (P= .54). A higher number of venous thrombotic episodes occurred in the high-dose corticosteroid group compared with the low-dose corticosteroid therapy group (12% vs 6%), but the difference was not statistically significant (P= .3).. The incidence of deep vein thrombosis is lower than previously reported in the literature. There was a trend to a higher incidence of thrombosis in patients receiving high-dose corticosteroid therapy.

High-dose melphalan-based autotransplants for multiple myeloma: the Arkansas experience since 1989 in 3077 patients.
    Cancer, 2008, Apr-15, Volume: 112, Issue:8

    In this report, the authors describe their collective experience with melphalan-based autotransplants since the inception of their program at the University of Arkansas for Medical Sciences in 1989.. The authors evaluated the clinical outcomes of 3077 successive patients with multiple myeloma (MM) who underwent at least 1 melphalan-based autotransplantation at the University of Arkansas. Of these, 1078 patients were enrolled on front-line Total Therapy (TT) protocols (TT-P) TT1, TT2, and TT3; 1104 patients were entered on protocols for newly diagnosed or previously treated patients (non-TT-P); and 895 patients were treated off protocol (non-P).. The 10-year overall survival (OS) rates after first transplantation were 41%, 19%, and 11% (P< .001) for the TT-P, non-TT-P, and non-P groups, respectively. In the TT-P group, the median OS was 72 months on TT1, was not reached at >or= 7 years on TT2, and was 88% at 2 years on TT3. Among 2683 patients with complete baseline data, absence of hypodiploidy/chromosome 13 deletion, beta-(2)-microglobulin <3.0 mg/L, C-reactive protein <6 mg/L, albumin >or= 3.0 g/dL, and platelet count >or= 100,000/microL all were associated independently with superior OS (P< .001), event-free survival (P< .001), and duration of complete remission (P< .001).. The results from this large, single-institution experience demonstrated that >10-year OS was accomplished in >40% of all patients enrolled on TT-P, whereas such success was observed in only 15% of the remaining patients (including 25% in the presence of all 5 good-risk features). Superior outcomes with protocol-based, primary transplant regimens such as TT-P draw attention to the importance of applying the best available therapies upfront.

Impact of genetic abnormalities on survival after allogeneic hematopoietic stem cell transplantation in multiple myeloma.
    Leukemia, 2008, Volume: 22, Issue:6

    We analyzed the prognostic impact of the most frequent genetic abnormalities detected by fluorescence in situ hybridization in 101 patients with multiple myeloma, who underwent allogeneic hematopoietic stem cell transplantation (HSCT) after melphalan/fludarabine-based reduced conditioning. The incidences of abnormalities in the present analysis were as follows: del(13q14) (61%), t(11;14)(q13;q32) (14%), t(4;14)(p16.3;q32) (19%), MYC-gain gains (8q24) (21%), del(17p13) (16%) and t(14;16)(q32;q23) (5%). None of the patients had t(6;14)(p25;q32). The overall complete remission (CR) rate was 50% with no differences between the genetic abnormalities except for patients with del(17p13) who achieved less CR (7 vs 56%; P=0.001). Univariate analysis revealed a higher relapse rate in patients aged >50 years (P=0.002), patients with del(13q14) (P=0.006) and patients with del(17p13) (P=0.003). In multivariate analyses, only del(13q14) (HR: 2.34, P=0.03) and del(17p13) (HR: 2.24; P=0.04) significantly influenced the incidence of relapse, whereas for event-free survival, only age (HR 2.8; P=0.01) and del(17p13) (HR: 2.05; P=0.03) retained their negative prognostic value. These data show that del(17p13) is a negative prognostic factor for achieving CR as well as for event-free survival after HSCT. Translocation t(4;14) might be overcome by allogeneic HSCT, which will have implication for risk-adapted strategies.

Expression of c-Kit isoforms in multiple myeloma: differences in signaling and drug sensitivity.
    Haematologica, 2008, Volume: 93, Issue:6

    c-Kit is expressed in the plasma cells from 30% of patients with multiple myeloma. Two different isoforms of c-Kit, characterized by the presence or absence of the tetrapeptide sequence GNNK in the extracellular domain, have been described. However, their expression and function in myeloma cells are unknown. We explored the function and expression of these c-Kit isoforms in myeloma cells.. Expression of c-Kit isoforms was investigated by reverse transcriptase polymerase chain reaction in fresh plasma cells from patients and cell lines. The function of these c-Kit isoforms was analyzed upon expression in myeloma cells. Signaling was investigated by western blotting using antibodies specific for activated forms of several signaling proteins. The impact of c-Kit on the action of drugs commonly used in the treatment of multiple myeloma was investigated by MTT proliferation assays.. Fresh plasma cells from patients as well as myeloma cell lines expressed the two isoforms of c-Kit. Retroviral infection of myeloma cells with vectors that code for c-Kit-GNNK+ or c-Kit-GNNK- forms demonstrated differences in the kinetics of phosphorylation between these isoforms. Stem cell factor-induced activation of the GNNK- form was faster and more pronounced than that of the GNNK+ form, whose activation, however, lasted for longer. The c-Kit receptors weakly activated the Erk1/2 and Erk5 pathways. Both receptors, however, efficiently coupled to the PI3K/Akt pathway, and stimulated p70S6K activation. The latter was sensitive to the mTOR inhibitor, rapamycin. Studies of drug sensitivity indicated that cells expressing the GNNK- form were more resistant to the anti-myeloma action of bortezomib and melphalan.. Our data indicate that c-Kit expression in multiple myeloma cells is functional, and coupled to survival pathways that may modulate cell death in response to therapeutic compounds used in the treatment of this disease.

HSP70 inhibition reverses cell adhesion mediated and acquired drug resistance in multiple myeloma.
    British journal of haematology, 2008, Volume: 142, Issue:4

    Heat shock proteins (HSPs) are a super family of highly conserved molecular chaperone proteins, which are induced in response to stress. HSP70 has been demonstrated to inhibit apoptosis induced by a number of chemotherapeutic agents. Previous investigations have suggested the development of drug resistance in multiple myeloma (MM) cells after adhesion to stroma. This study used MM cell lines and primary plasma cells to determine if HSP70 had a role in development of chemo resistance. Adhesion of MM cells to either bone marrow stromal cells or fibronectin (FN) enhanced HSP70 expression. Inhibition of the HSP70 expression decreased 8226 cell adhesion to stroma or FN and induced more apoptosis in FN-adhered 8226 cells than in suspension cultures at 24 h. Further, HSP70 inhibitors enhanced melphalan-induced apoptosis and reversed melphalan-induced cell adhesion-mediated drug resistance (CAM-DR) phenotype. In addition, compared to parental cells, KNK-437, a heat shock factor inhibitor caused more apoptosis in melphalan-resistant 8226/LR5 cells and sensitized them to melphalan. Primary CD138 positive cells showed high expression of HSPA4 mRNA, and KNK-437 caused apoptosis in these cells. In conclusion, our data suggest inhibition of HSP70, reduced adhesion and caused apoptosis of both acquired and de novo drug resistant MM cells.

Targeting mitochondrial factor Smac/DIABLO as therapy for multiple myeloma (MM).
    Blood, 2007, Feb-01, Volume: 109, Issue:3

    Second mitochondria-derived activator of caspases (Smac) promotes apoptosis via activation of caspases. Here we show that a low-molecular-weight Smac mimetic LBW242 induces apoptosis in multiple myeloma (MM) cells resistant to conventional and bortezomib therapies. Examination of purified patient MM cells demonstrated similar results, without significant cytotoxicity against normal lymphocytes and bone marrow stromal cells (BMSCs). Importantly, LBW242 abrogates paracrine MM cell growth triggered by their adherence to BMSCs and overcomes MM cell growth and drug-resistance conferred by interleukin-6 or insulinlike growth factor-1. Overexpression of Bcl-2 similarly does not affect LBW242-induced cytotoxicity. Mechanistic studies show that LBW242-induced apoptosis in MM cells is associated with activation of caspase-8, caspase-9, and caspase-3, followed by PARP cleavage. In human MM xenograft mouse models, LBW242 is well tolerated, inhibits tumor growth, and prolongs survival. Importantly, combining LBW242 with novel agents, including tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) or the proteasome inhibitors bortezomib and NPI-0052, as well as with the conventional anti-MM agent melphalan, induces additive/synergistic anti-MM activity. Our study therefore provides the rationale for clinical protocols evaluating LBW242, alone and together with other anti-MM agents, to improve patient outcome in MM.

High-dose melphalan versus busulfan, cyclophosphamide, and etoposide as preparative regimens for autologous stem cell transplantation in patients with multiple myeloma.
    Leukemia research, 2007, Volume: 31, Issue:8

    High-dose chemotherapy (HDC) with autologous stem cell transplant (ASCT) has improved response rates and survival for patients with multiple myeloma (MM). We report a single-institution experience using two conditioning regimens, busulfan, cyclophosphamide, and etoposide (BCV) or high-dose melphalan (HDM). Between July 1992 and August 2003, 110 patients with MM (median age=56.1) underwent HDC with ASCT using either BCV (n=62) or HDM (n=48) in sequential cohorts as the preparative regimen. Overall response rates, progression-free survival, and median overall survival were similar. BCV and HDM confer similar long-term outcomes with similar toxicity profiles as conditioning regimens prior to autologous stem cell transplant in patients with MM.

Percutaneous vertebroplasty at C2: case report of a patient with multiple myeloma and a literature review.
    European spine journal : official publication of the European Spine Society, the European Spinal Deformity Society, and the European Section of the Cervical Spine Research Society, 2007, Volume: 16 Suppl 3

    Percutaneous vertebroplasty (PVP) of the axis is a challenging procedure which may be performed by a percutaneous or a transoral approach. There are few reports of PVP at the C2 level. We report a case of unstable C2 fracture treated with the percutaneous approach. The fracture was the first manifestation of multiple myeloma in a previously healthy 47-year-old woman. After local radiotherapy and chemotherapy, the fracture was still unstable and the patient had been continuously wearing a stiff cervical collar for 9 months. Complication-free PVP resulted in pain relief and stabilization and use of the cervical collar could be discontinued. At 18 months follow-up the patient remained free from pain, the fracture was stable and she had returned to work.

Multiple Myeloma: Molecular Imaging with 11C-Methionine PET/CT--Initial Experience.
    Radiology, 2007, Volume: 242, Issue:2

    To prospectively assess molecular imaging of multiple myeloma (MM) by using the radiolabeled amino acid carbon 11 ((11)C) methionine and positron emission tomography (PET)/computed tomography (CT).. The study was approved by the institutional local ethics committee and the national radiation protection authorities. All patients with MM and control patients gave written informed consent. Nineteen patients with MM (11 women, eight men; age range, 42-64 years) and 10 control patients with hyperparathyroidism without hematologic diseases (six women, four men; age range, 43-75 years) underwent PET/CT 20 minutes after injection of a mean of 1.0 GBq +/- 0.2 (standard deviation) (11)C-methionine. Presence and extent of CT-assessed tumor manifestations and (11)C-methionine bone marrow (BM) uptake were determined on the basis of maximum standardized uptake value (SUV(max)). BM imaging patterns, normal BM, and maximal lesion (11)C-methionine uptake in patients with MM were compared with those in control patients. In two patients with MM, sulfur 35 ((35)S) methionine uptake in freshly isolated BM plasma cells was measured. Values for SUV(max) of groups were compared by using the Mann-Whitney test on a per-patient basis.. (35)S-methionine uptake of plasma cells was five- to sixfold higher than in normal BM cells. (11)C-methionine BM uptake in control patients was homogeneous and low. All patients with MM except one with exclusively extramedullary myeloma had (11)C-methionine-positive lesions. Maximal lesion and normal BM (11)C-methionine mean SUV(max) were 10.2 +/- 3.5 and 4.3 +/- 2.0, respectively, and thus were significantly higher than that of BM in the control group (mean, 1.8 +/- 0.3; P < .001). Extramedullary MM was clearly visible in three patients (mean SUV(max), 7.2 +/- 2.4). Additional (11)C-methionine-positive lesions in normal cancellous bone were found in nearly all patients with MM. In pretreated patients with MM, a moderate fraction of osteolytic lesions had no (11)C-methionine uptake.. On the basis of increased methionine uptake in plasma cells, active MM can be imaged with (11)C-methionine PET/CT.

Outpatient high-dose melphalan in multiple myeloma patients.
    Transfusion, 2007, Volume: 47, Issue:1

    The brief period of neutropenia and limited nonmarrow toxicity after high-dose melphalan (HDM) provide a rationale for outpatient treatment.. Our experience with HDM (140-200 mg/m(2)) in 90 consecutive transplant episodes was retrospectively reviewed. Most patients were treated in an outpatient setting. Patients without a primary care provider (PCP) were electively admitted before the anticipated onset of neutropenia. Ceftriaxone was added to ciprofloxacin at the onset of neutropenia. All febrile patients were admitted.. The median time from peripheral blood progenitor cell infusion to onset of neutropenia was 5 days (range, 4-6 days), and the mean duration of neutropenia was 5 days (range, 4-7 days). Thirty-eight transplants (42%) were performed entirely in the outpatient setting. The mean duration of hospitalization was 2.2 days in patients not electively admitted. The use of ceftriaxone was associated with a decreased risk for fever (39% vs. 79%) and reduced duration of hospitalization (1.6 days vs. 4.5 days) for nonelectively admitted patients. There was no treatment-related mortality.. Ambulatory therapy with HDM is safe and can be achieved in a general outpatient setting. The predictable time to neutropenia allows even poor candidates for outpatient therapy to be admitted electively on Day +4. The apparent beneficial effect of ceftriaxone needs to be confirmed in randomized trials.

[Four cases of therapy-related leukemia in multiple myeloma].
    Gan to kagaku ryoho. Cancer & chemotherapy, 2007, Volume: 34, Issue:1

    We have experienced 4 cases of therapy-related leukemia (TRL) in 119 patients with multiple myeloma (MM) who had received combination chemotherapy including alkylating agents between 1988 and 1998. All 4 cases were acute myelogenous leukemia, 3 were males and 1 was female. Median age at diagnosis of MM was 60 years, and median time to TRL from diagnosis of MM was 5.5 years. The chromosome abnormalities were found in 3 of those cases. All 4 cases were resistant to antileukemic chemotherapy, and median survival time from TRL was only 5.5 months. The TRL in MM is thought to be a more important problem, because recently the treatment for this disease has become more intensive, including high-dose chemotherapy supported by autologous stem cell transplantation.

The Bcl-2 family protein inhibitor, ABT-737, has substantial antimyeloma activity and shows synergistic effect with dexamethasone and melphalan.
    Clinical cancer research : an official journal of the American Association for Cancer Research, 2007, Jan-15, Volume: 13, Issue:2 Pt 1

    The aim of this study is to investigate the antimyeloma activity of a novel Bcl-2 family inhibitor, ABT-737, in preclinical treatment of multiple myeloma.. The antimyeloma activity of ABT-737 was evaluated in cultured myeloma cell lines and patient myeloma samples, and in a xenograft mouse myeloma model. Drug combination therapy using ABT-737 with other commonly used myeloma drugs was also investigated.. MY5 and JJN3 cell lines exhibited the most sensitivity to ABT-737 with an EC(50) of 0.2 and 0.5 micromol/L, respectively, with increased cell apoptosis and elevated activated caspase-3. We identified two distinct groups of myeloma patient samples that were either sensitive or resistant to the drug. Four of 15 patient bone marrow samples (27%) were highly sensitive to ABT-737 at doses of 0.25 and 0.5 micromol/L, which eliminated 80% to 90% of myeloma cells as a result of cellular apoptosis 3 days after drug treatment. ABT-737 showed a synergistic effect when combined with dexamethasone or melphalan in inducing myeloma cell death. Furthermore, the dexamethasone-resistant MM1(Dex)R myeloma cell line was highly sensitive to 0.2 micromol/L ABT-737. As determined by colony assay, little or no detectable toxicity to patient hematologic progenitor cells was observed at 1 micromol/L ABT-737. ABT-737 dose dependently suppressed tumor growth in a xenograft MY5 mouse model.. These studies show substantial antimyeloma activity of ABT-737 as a single agent or in combination with dexamethasone or melphalan and suggest a rationale for future clinical trials.

Autologous peripheral blood stem cell transplantation in multiple myeloma using oral versus I.V. melphalan.
    Annals of hematology, 2007, Volume: 86, Issue:4

    Autologous peripheral blood stem cell transplantation is the therapy of choice for the treatment of multiple myeloma (MM) patients younger than 70 years old. Between August 1993 and November 2004, 54 patients with MM were autografted after conditioning with high-dose oral melphalan 140 mg/m(2) in combination with etoposide and carmustine (28 patients) or with high-dose melphalan 200 mg/m(2) I.V. (26 patients). The oral and IV melphalan groups were comparable. There were no significant differences in disease-free survival (DFS) and overall survival (OS) between the groups; however, in patients transplanted in remission, OS and DFS were better in the I.V. melphalan group. Four good-prognostic factors were identified: interval between diagnosis and transplant <18 months, number of prior chemotherapy lines < or =2, remission status (complete or partial), and the use of I.V. melphalan. In conclusion, I.V. melphalan is the therapy of choice for conditioning patients with MM who are in remission.

Up-regulation of c-Jun inhibits proliferation and induces apoptosis via caspase-triggered c-Abl cleavage in human multiple myeloma.
    Cancer research, 2007, Feb-15, Volume: 67, Issue:4

    Here we show the antimyeloma cytotoxicity of adaphostin and carried out expression profiling of adaphostin-treated multiple myeloma (MM) cells to identify its molecular targets. Surprisingly, c-Jun was the most up-regulated gene even at the earliest point of analysis (2 h). We also observed adaphostin-induced c-Abl cleavage in immunoblot analysis. Proteasome inhibitor bortezomib, but not melphalan or dexamethasone, induced similar effects, indicating unique agent-dependent mechanisms. Using caspase inhibitors, as well as caspase-resistant mutants of c-Abl (TM-c-Abl and D565A-Abl), we then showed that c-Abl cleavage in MM cells requires caspase activity. Importantly, both overexpression of the c-Abl fragment or c-Jun and knockdown of c-Abl and c-Jun expression by small interfering RNA confirmed that adaphostin-induced c-Jun up-regulation triggers downstream caspase-mediated c-Abl cleavage, inhibition of MM cell growth, and induction of apoptosis. Finally, our data suggest that this mechanism may not only be restricted to MM but may also be important in a broad range of malignancies including erythroleukemia and solid tumors.

Experimental study enhancing the chemosensitivity of multiple myeloma to melphalan by using a tissue-specific APE1-silencing RNA expression vector.
    Clinical lymphoma & myeloma, 2007, Volume: 7, Issue:4

    Because of a developing resistance to chemotherapy agents, multiple myeloma (MM) has been an incurable disease until now. As a means to overcome MM tumor cell resistance and/or sensitize tumor cells to chemotherapeutic treatments currently used, we examined the role of human apurinic/apyrimidinic endonuclease 1 (APE1) in resistance and prognosis in patients with MM.. Multiple myeloma cells were analyzed by using bone marrow specimens from 32 patients with MM and 10 normal volunteers.. The positive rate of APE1 protein expression was 65.6% in the bone marrow specimens of patients with MM with known clinical outcome. Positive rate of APE1 expression beyond grade 2 in the relapsed/refractory group was significantly higher than that in the untreated group. No positive results of grade > 2 were detected in bone marrow specimens from patients with noncancerous disease. It was also confirmed that the amount of APE1 protein in KM3 cells was positively correlated with the dose and action time of melphalan. Because APE1 was overexpressed in refractory/relapsed MM cells, siRNA-targeted technology was used to decrease APE1 levels in KM3 cells, with protein levels deceasing to 80%-90% within 24 hours and continuing to decease for 72 hours. The best dose and time of inhibiting expression of APE1 protein were 3 mug and 2 days long. A decrease in APE1 levels in siRNA-treated KM3 cells led to enhanced cell sensitization to melphalan.. The findings herein present prognostic and therapeutic implications for treating relapsed/refractory MM. The APE1-silencing RNA results demonstrate the feasibility of the therapeutic modulation of APE1 using a variety of molecules and approaches.

High dose melphalan or intermediate dose melphalan can be well tolerated and result in good response rates in selected elderly patients with myeloma.
    Leukemia research, 2007, Volume: 31, Issue:8

    We have used two strategies for treating myeloma patients aged 65-75 years. Those fit enough underwent Cyclophosphamide mobilisation and PBSCT using melphalan 200mg/m(2) (HDM) (n=15, median 67 years). Those less fit were mobilised with G-CSF and received melphalan 70mg/m(2) (IDM) (n=15, median 69 years). Where possible sufficient PBSC were collected so that patients not in CR after their first IDM, underwent a second IDM procedure (n=6). The treatment was well tolerated with zero day+100 TRM. Median cell dose was 4.85x10(6)CD34+cells/kg and 2.7x10(6) in the HDM and IDM groups, respectively. Neutrophil engraftment was faster in the HDM group but despite this there was a trend to earlier discharge in the IDM group (13 days versus 15 days) and lower antibiotic and anti-fungal usage, suggesting better tolerability. Response rates were similar with CRs achieved in 7/15 patients receiving HDM and 9/15 receiving IDM (6 after the first and 3 after the second procedure). Three patients did not undergo a second IDM due to insufficient cells. In the IDM group 11/15 remain alive at a median follow up of 14 months with 5 in CR, whilst in the HDM group 12/15 are alive with 5 in CR at a median follow up of 15.5m. We conclude both approaches have comparable efficacy but that IDM may be better tolerated in an older age group.

Treatment of diuretic refractory pleural effusions with bevacizumab in four patients with primary systemic amyloidosis.
    American journal of hematology, 2007, Volume: 82, Issue:5

    Refractory pleural effusions present a challenging management problem and are associated with a poor prognosis in patients with primary systemic amyloidosis (AL). We report a series of four patients with AL who presented with bilateral pleural effusions that were refractory to diuretic therapy. After treatment with bevacizumab, an antivascular endothelial growth factor (VEGF) antibody, three of the four patients had improvement in their pleural effusions, peripheral edema, and functional status. Additional studies are needed to further define the role of bevacizumab in the management of this group of patients.

Inhibition of adenosine monophosphate-activated protein kinase induces apoptosis in multiple myeloma cells.
    Anti-cancer drugs, 2007, Volume: 18, Issue:4

    In this study, we show that adenosine monophosphate-activated protein kinase (AMPK) is expressed and activated in multiple myeloma cells. The inhibition of AMPK induced growth arrest and reduction of cell viability in the cell viability assay using the water-soluble tetrazolium salt 4-[3-(4-iodophenyl)-2-(4-nitrophenyl)-2H-5-tetrazolio]-1,3-benzene disulfonate (WST-1 assay). Induction of apoptosis was determined by annexin-V and propidium iodide staining. The prevention of apoptosis using the pancaspase inhibitor ZVAD-fmk and caspase-3 cleavage upon incubation with the AMPK inhibitor (AMPKI) is shown. Furthermore, incubation of myeloma cells with AMPKI resulted in the downregulation of pAMPK, Mcl-1 and Bcl-xL. Coincubation of AMPKI and melphalan led to a strong additional increase of apoptosis in myeloma cells. We conclude that AMPKI has a strong antimyeloma activity in vitro and represents a new targeted strategy in the treatment of multiple myeloma.

    Although high-dose therapy is considered the standard therapy for younger patients with multiple myeloma (MM), the advantages of performing a second transplant remain debated. The current study was conducted to evaluate the efficacy and the feasibility of a front-line double transplant program in young MM patients.. A total of 153 MM patients aged

Collection of peripheral blood stem cells in new patients with myeloma receiving minimal or no prior cytoreductive therapy.
    Hematology (Amsterdam, Netherlands), 2007, Volume: 12, Issue:2

    The aim of the study was to evaluate whether adequate stem cells (CD34+) could be harvested at presentation in myeloma patients such that high dose melphalan (HDM) with autologous stem cell rescue can be offered as primary therapy. The regimes either involved no prior cytoreductive chemotherapy (steroids only, n = 31) or a single course of VAD (n = 22). The median number of CD34 cells collected with steroids was 1.3 x 10(6) (0.2-5.6) compared to 4.6 x 10(6) (0.3-19.2) cells/kg with VAD (P < 0.0001). We conclude that it is possible to collect stem cells from myeloma patients at presentation with minimal prior therapy. Using this strategy, of a single prior course of chemotherapy followed by immediate harvest, it is feasible to offer early high-dose therapy in clinical situations where this is important.

CD4+ T lymphocyte counts after autologous transplantation in multiple myeloma: a retrospective study.
    Leukemia & lymphoma, 2007, Volume: 48, Issue:3

    The risk for opportunistic infections is correlated with low CD4+ T lymphocyte counts in patients with HIV. We performed a retrospective analysis in 54 patients with multiple myeloma undergoing high-dose melphalan chemotherapy + autologous peripheral blood stem cell transplantation to better define the value of routine control of CD4+ T lymphocyte counts in this important patient group. In 61% of our patients, CD4+ T lymphocyte counts after recovery from neutropenia were <200/microl and <100/microl in 24% (median = 181/microl). Overall survival, progression-free survival, response to antineoplastic therapy and frequency of post-transplant infections were not significantly different when patients with CD4+ T lymphocyte counts <200/microl and >200/microl were compared. However, overall survival was significantly shorter in the subgroup of 13 patients with very low CD4+ T lymphocyte counts (<100/microl) (P = 0.036). In 79.6% of all patients, at least one infection NCI-CTC grade II - IV developed within 100 days post-transplant. Opportunistic infections were rare. This analysis suggests that patients with CD4+ T lymphocyte counts < 100/microl may have a poorer prognosis.

Reduced intensity conditioning with thiotepa, fludarabine, and melphalan is effective in advanced multiple myeloma.
    Leukemia & lymphoma, 2007, Volume: 48, Issue:4

    Fifty-three patients with multiple myeloma (MM) underwent an allogeneic stem cell transplant (HSCT) from their HLA identical siblings using a reduced-intensity conditioning consisting of thioteopa 5 mg/kg, fludarabine 90 mg/m(2), and melphalan 80 mg/m(2). Their median age was 52 years (range 38 - 68) and the interval from diagnosis 12 months. Forty-three patients (82%) had advanced disease and 33 had previously been treated with high-dose therapy with one (N = 21), or more (N = 12) autologus transplants. Ten (18%) had their allograft programmed after induction chemotherapy. The majority (N = 44) received peripheral blood as stem cell source. Acute graft-versus-host disease (GVHD) grade II - IV developed in 45%, but grade III - IV in only 5%. Cumulative incidence of chronic GVHD was 64%. Sixty-two per cent were in complete remission (CR) following transplantation. Transplant-related mortality was 13%. Relapse incidence was 32%. With a median follow-up of 22 months, 3-year overall survival is 45% and progression free survival (PFS) 37%. The thiotepa, fludarabine, and melphalan conditioning regimen can produce remissions in the majority of MM patients with a limited transplant mortality rate. When used as first line treatment the results of transplantation appear even more encouraging.

[The standard treatments for patients with hematological malignancies in Japan].
    Gan to kagaku ryoho. Cancer & chemotherapy, 2007, Volume: 34, Issue:5

    Recently, the standard treatments for hematological malignancies have shown dramatic improvement. For chronic myeloid leukemia, imatinib has become the treatment of choice in initial treatment, and its long-term effectiveness and safety have been confirmed. For acute myelogenous leukemia, cytarabine with anthracycline agent is believed to be the standard treatment in first remission induction therapy. To improve the efficacy of the first remission induction chemotherapy, the addition of gemutuzumab ozogamicin has been investigated intensively all over the world. However, there are many obstacles to conducting its clinical trial in Japan. The addition of rituximab to CHOP improves the survival of patients with diffuse large B-cell lymphoma. For follicular lymphoma patients, rituximab with conventional chemotherapies are considered the standard treatments, but the question of which conventional chemotherapy is better is unsolved. MP therapy had long been the standard treatment for elderly patients with multiple myeloma, but MP therapy plus thalidomide with MP therapy has been found to be superior. In patients who are candidates for autologous stem-cell transplantation, VAD therapy or high-dose dexamethasone therapy followed by autologous stem-cell transplantation is considered the treatment of choice. But the number of transplantations and the timing of second transplantation need more investigation. Considering the overall situation with regard to the standard treatments of hematological malignancies in Japan, there is little difference in practice from western countries. However, the framework of conducting clinical trials to investigate standard treatment in Japan is unsatisfactory.

Targeting NF-kappaB pathway with an IKK2 inhibitor induces inhibition of multiple myeloma cell growth.
    British journal of haematology, 2007, Volume: 138, Issue:2

    The pathophysiologic basis for multiple myeloma (MM) has been attributed to the dysregulation of various paracrine or autocrine growth factor loops and to perturbations in several signal transduction pathways including IkappaB kinase/nuclear factor-kappaB (IKK/NF-kappaB). The present study aimed at investigating the effect of a pharmaceutical IKK2 inhibitor, the anilinopyrimidine derivative AS602868, on the in vitro growth of 14 human MM cell lines (HMCL) and primary cells from 13 patients. AS602868 induced a clear dose-dependent inhibition of MM cell growth on both HMCL and primary MM cells, which was the result of a simultaneous induction of apoptosis and inhibition of the cell cycle progression. Combination of AS602868 with suboptimal doses of melphalan or Velcade showed an additive effect in growth inhibition of HMCL. AS602868 also induced apoptosis of primary myeloma cells. Importantly, AS602868 did not alter the survival of other bone marrow mononuclear cells (CD138(-)) co-cultured with primary MM (CD138(+)) cells, except for CD34(+) haematopoietic stem cells. The results demonstrate the important role of NF-kappaB in maintaining the survival of MM cells and suggest that a pharmacological inhibition of the NF-kappaB pathway by the IKK2 inhibitor AS602868 can efficiently kill HMCL and primary myeloma cells and therefore might represent an innovative approach for treating MM patients.

Genetic polymorphisms in the amino acid transporters LAT1 and LAT2 in relation to the pharmacokinetics and side effects of melphalan.
    Pharmacogenetics and genomics, 2007, Volume: 17, Issue:7

    Melphalan is widely used in the treatment of multiple myeloma. Pharmacokinetics of this alkylating drug shows high inter-individual variability. As melphalan is a phenylalanine derivative, the pharmacokinetic variability may be determined by genetic polymorphisms in the L-type amino acid transporters LAT1 (SLC7A5) and LAT2 (SLC7A8).. Pharmacokinetics were analysed in 64 patients after first administration of intravenous melphalan. Severity of side effects was documented according to WHO criteria. Genomic DNA was analysed for polymorphisms in LAT1 and LAT2 by sequencing of the entire coding region, intron-exon boundaries and 2 kb upstream promoter region. Selected polymorphisms in the common heavy chain of both transporters, the protein 4F2hc (SLC3A2), were analysed by single nucleotide primer extension.. Melphalan pharmacokinetics was highly variable with up to 6.2-fold differences in total clearance. A total of 44 polymorphisms were identified in LAT1 and 21 polymorphisms in LAT2. From all variants, only five were in the coding region and only one heterozygous non-synonymous polymorphism (Ala94Thr) was found in LAT2. Numerous polymorphisms were found in the LAT1 and LAT2 5'-flanking regions but did not correlate with expression of the respective genes. No significant correlations could be observed between the polymorphisms in 4F2hc, LAT1, and LAT2 with melphalan pharmacokinetics or with melphalan side effects.. The study confirmed that these transporter genes are highly conserved, particularly in the coding sequences. Genetic variation in 4F2hc, LAT1, and LAT2 does not appear to be a major cause of inter-individual variability in pharmacokinetics and of adverse reactions to melphalan.

Oral mucositis and outcomes of autologous hematopoietic stem-cell transplantation following high-dose melphalan conditioning for multiple myeloma.
    The journal of supportive oncology, 2007, Volume: 5, Issue:5

    The purpose of this study was to assess the relationship between oral mucositis (OM) and adverse clinical and economic outcomes of autologous hematopoietic stem-cell transplantation (HSCT) following high-dose melphalan (Alkeran) conditioning in patients with multiple myeloma. A retrospective study of 115 consecutive autologous HSCT recipients with multiple myeloma who received high-dose melphalan conditioning before transplantation was undertaken at a single academic center. OM severity was assessed twice weekly using a validated scale beginning 3-4 days following conditioning and continuing until hospital discharge or day 28, whichever occurred first. OM was graded, based on presence/extent of erythema/ulceration across eight oropharyngeal sites, as follows: 0 = no erythema or ulceration; I = erythema but no ulceration; II = ulceration, 1 site; III = ulceration, 2 sites; IV = ulceration, 3 sites; and V = ulceration, > or = 4 sites. Analyses examined the relationship between worst OM grade and selected clinical and economic outcomes, including days with fever, days of total parenteral nutrition (TPN),days of parenteral narcotic therapy, incidence of significant infection, and inpatient days and charges. The mean age of study subjects was 54 years; 19 patients (17%) received total-body irradiation, and 55 patients (48%) experienced OM grade > or = II (ie, ulceration). The worst OM grade was significantly (P < 0.05) associated with numbers of days of TPN and parenteral narcotic therapy, length of hospitalization, and total inpatient charges. Worst OM grade was not associated with the number of febrile days or the risk of significant infection. OM is associated with worse clinical and economic outcomes in multiple myeloma patients undergoing autologous HSCT following high-dose melphalan conditioning.

Antimyeloma effects of arsenic trioxide are enhanced by melphalan, bortezomib and ascorbic acid.
    British journal of haematology, 2007, Volume: 138, Issue:4

    Arsenic trioxide (ATO) induces apoptosis of malignant plasma cells through multiple mechanisms, including inhibition of DNA binding by nuclear factor kappa-B, a key player in the development of chemoresistance in multiple myeloma (MM). This activity suggests that ATO may be synergistic when combined with other active antimyeloma drugs. To evaluate this, we examined the antimyeloma effects of ATO alone and in combination with bortezomib, melphalan and ascorbic acid (AA) both in vitro and in vivo using a severe combined immunodeficient (SCID)-hu murine myeloma model. Marked synergistic antimyeloma effects were demonstrated when human MM Los Angeles xenograft IgG lambda light chain (LAGlambda-1) cells were treated in vitro with ATO and any one of these agents. SCID mice bearing human MM LAGlambda-1 tumours were treated with single-agent ATO, bortezomib, melphalan, or AA, or combinations of ATO with either bortezomib or melphalan and AA. Animals treated with any of these drugs alone showed tumour growth and increases in paraprotein levels similar to control mice, whereas animals treated with ATO-containing combinations showed markedly suppressed tumour growth and significantly reduced serum paraprotein levels. These in vitro and in vivo results suggest that addition of ATO to other antimyeloma agents may result in improved outcomes for patients with relapsed or refractory MM.

Oral melphalan, dexamethasone, and thalidomide for the treatment of refractory multiple myeloma.
    International journal of hematology, 2007, Volume: 86, Issue:1

    We present a patient with refractory multiple myeloma who showed a good response to a combination therapy with oral melphalan, dexamethasone, and thalidomide (MDT). A 48-year-old woman with myeloma refractory to thalidomide, dexamethasone, and clarithromycin received 6 mg melphalan for 4 days every 6 weeks in combination with thalidomide (100 mg daily) and dexamethasone (5 mg daily for 2 days every week). Four months after the initiation of MDT therapy, a 78% reduction of monoclonal protein was achieved. Although the efficacy of oral MDT combination therapy in elderly patients with newly diagnosed myeloma has been reported, the present data demonstrate the effectiveness of MDT therapy for refractory myeloma and warrant further exploration with this MDT regimen to treat myeloma.

[Nutritional pathway for autologous stem cell transplantation].
    Gan to kagaku ryoho. Cancer & chemotherapy, 2007, Volume: 34, Issue:8

    We developed a nutritional pathway for autologous stem cell transplantation (SCT) to be applied in our transplantation unit. We performed autologous SCT for 37 patients with malignant lymphoma and multiple myeloma during from April 2003 to July 2005. For 10 of them who underwent SCT since 2005,we intervened with nutritional support using our original nutritional pathway,to monitor the clinical course of SCT from the aspect of dietetics with a dietician making assessments of the individual nutrition status. From comparing the 2 groups with (n=27) or without (n=10) the nutritional pathway, oral intake at day 14 was significantly increased from 1,038 kcal to 1,440 kcal,and at discharge developed from 1,167 kcal to 1,446 kcal without statistical significance. Patients whose body weight decreased more than 5% were reduced from 52%(14/27) to 10%(1/10),and 3 days reduction of the CVC insertion period was observed after the intervention. Although the long-term clinical outcome was not fully evaluated, the efficacy of nutritional pathway for autologous SCT was suggested.

Post-transplant outcomes of induction therapy for myeloma: thalidomide and dexamethasone versus doxorubicin, vincristine, and dexamethasone prior to high-dose melphalan with autologous stem cell support.
    American journal of hematology, 2007, Volume: 82, Issue:12

    High-dose melphalan with autologous stem cell support improves survival as part of initial therapy for myeloma. Previous studies of pre-transplant induction regimens have compared paraprotein response rates but not long-term outcomes after transplant. We reviewed the records of all patients with multiple myeloma who received an autologous stem cell transplant at the University of Pennsylvania Medical Center. We compared outcomes for 69 patients who received high-dose melphalan conditioning after January 1, 2003 as part of initial therapy for myeloma, including 41 patients who received anthracycline-based induction (VAD or DVD) and 28 patients who received thalidomide and dexamethasone induction. Baseline characteristics in these two groups were not different, though potentially clinically important differences were apparent in assignment to post-transplant consolidation and maintenance therapy. Despite similar response rates during induction therapy, thalidomide and dexamethasone induction was associated with better progression-free survival (hazard ratio 0.18, P = 0.011) after transplant. This effect persisted in multivariable regression models including baseline characteristics and post-transplant treatment. Overall survival was not different between the two groups. These results suggest that the use of thalidomide during induction therapy may lead to improved long-term outcomes after transplant. Future trials comparing induction therapies should examine progression-free and overall survival after transplant to confirm this benefit.

Deletion of the short arm of chromosome 1 (del 1p) is a strong predictor of poor outcome in myeloma patients undergoing an autotransplant.
    Biology of blood and marrow transplantation : journal of the American Society for Blood and Marrow Transplantation, 2007, Volume: 13, Issue:9

    Several chromosomal abnormalities detected by conventional cytogenetic analysis have an adverse impact on the outcome in myeloma patients. A wide spectrum of abnormalities involving chromosomes 1, 13, 14, and 17 has been described. We analyzed the outcome of 83 patients with clonal cytogenetic abnormalities, who underwent high-dose therapy and autologous stem cell transplantation for multiple myeloma at our institution. Clonal abnormalities were detected at diagnosis by conventional cytogenetic analysis in 83 patients. Patients underwent a single autologous transplant between April 2000 and May 2005. Preparative regimen was high-dose melphalan alone (73), or a combination of topotecan, melphalan, and cyclophosphamide (TMC=10). The most commonly observed chromosomal abnormalities were deletion of chromosome 13 (32%), hyperdiploidy (21%), deletion of chromosome 1p (18%), and t (11; 14) in 7% patients. Median follow-up among surviving patients was 25.5 months. Median interval from diagnosis to autotransplant was 7.7 months (range: 2.5-52). Median progression-free survival (PFS) for the entire group was 19 months and the median overall survival (OS) was 52 months. On univariate analysis, both PFS and OS were significantly shorter in patients with deletion 1p (P=.001 and <.0001, respectively). Thirty-two patients whose cytogenetic abnormalities returned to normal prior to autotransplant had longer PFS and OS than patients with persistent abnormalities (P=.02 and .08, respectively). Deletion 1p is associated with a significantly shorter remission and survival in patients undergoing high-dose therapy and a single autologous transplant for myeloma.

Multiple myeloma: a ten year study of survival and therapy in a developing nation.
    JPMA. The Journal of the Pakistan Medical Association, 2007, Volume: 57, Issue:7

    To analyze the survival related to therapeutic modalities and haematological indices at presentation with outcome performed on records of all multiple myeloma (MM) patients'.. A prospective study was conducted in the University of Benin Teaching Hospital, Nigeria from 1993 to 2003. Thirty patients were identified with diagnosis confirmed on the basis of atypical plasmacytosis (=30% in the bone marrow), monoclonal component in the serum or urine and radiological evidence of the typical skeletal lytic lesions.. Males (n = 20) outnumbered the females (n = 10), with a median age of 54 years. The mean duration of survival of all patients was 7 months (median 3 months; P < 0.0001) with only 13.3% of the patients surviving at two years. The mean duration of survival of 10 patients on either therapy of vincristine, adriamycin, dexamethasone (VAD) or 8 patients on melphalan, prednisolone (MP) was 3 months, significantly shorter than 21 months for the 5 patients on a combination of both forms of therapy at different times (COMB) (P = 0.0067). The Kaplan-Meier estimates of survival showed survival probability was least in those without definitive therapy (NONE) as expected.. Late presentation and inadequate treatment from poor compliance with therapy in a setting of poverty and ignorance are suggested as factors contributing to the poor survival of the patients studied

Lack of CD56 expression on myeloma cells is not a marker for poor prognosis in patients treated by high-dose chemotherapy and is associated with translocation t(11;14).
    Bone marrow transplantation, 2007, Volume: 40, Issue:11

    Lack of CD56 expression was reported to be associated with a poor prognosis in multiple myeloma (MM) patients treated with conventional chemotherapy. Aim of our retrospective study was to analyse whether CD56 expression on MM cells reveals as a prognostic factor in patients treated with high-dose chemotherapy. MM cells of 99 patients prior to treatment with high-dose chemotherapy were analysed for CD56 expression by flow cytometry. Multivariable analysis of event-free survival in these patients showed no statistically significant difference between the CD56(-) (n=28) and the CD56(+) (n=71) group. The lack of CD56 expression on MM cells of these patients correlated significantly with the presence of translocation (11;14) (t(11;14)) (estimated correlation coefficient=0.655 95%, confidence interval (0.481; 0.779)). In summary, our results indicate that lack of CD56 expression on MM cells is not a prognostic marker in patients treated with high-dose chemotherapy, but is associated with t(11;14).

Chemotherapy and survival for patients with multiple myeloma: findings from a large nationwide and population-based cohort.
    American journal of clinical oncology, 2007, Volume: 30, Issue:5

    To assess the patterns of chemotherapy use for patients with multiple myeloma and to determine if chemotherapy is effective in prolonging survival outside the clinical trial settings.. We studied a nationwide and population-based retrospective cohort of 4902 patients > or =65 years of age with stage II or III multiple myeloma from 1992 to 1999, identified from the Surveillance, Epidemiology, and End-Results-Medicare data. Multivariate logistic regression was used to estimate the odds ratio of receiving chemotherapy and Cox proportional hazard model was used to estimate the hazard ratio of mortality associated with chemotherapy.. Of 4902 patients with stage II or III multiple myeloma, 52.0% received chemotherapy during the course of the disease. The receipt of chemotherapy decreased significantly with age from 65.7% in the 65- to 69-year age group to 34.3% in those > or =80 years. Blacks (47.6%) were less likely to receive chemotherapy than whites (52.8%). Use of chemotherapy decreased significantly with comorbidity scores and increased over time. Risk of all-cause mortality was significantly reduced in patients who received chemotherapy compared with those who did not (adjusted hazard ratio = 0.65; 95% confidence interval = 0.61-0.69). A similar pattern as observed for myeloma-specific mortality (0.61; 0.56-0.67). Survival benefit increased with increasing cycles of chemotherapy (P < 0.001 for trend) and was significant across different age groups, gender, ethnic groups, and comorbidity scores.. Chemotherapy was significantly associated with increased survival in patients with multiple myeloma outside the clinical trial settings. This survival benefit was significant across different groups by age, gender, race, and comorbidity. A substantial number of patients with multiple myeloma did not receive chemotherapy.

[Treatment and survival of multiple myeloma patients on programmed hemodialysis].
    Terapevticheskii arkhiv, 2007, Volume: 79, Issue:8

    To analyse clinical picture of multiple myeloma (MM) and treatment results in MM patients on programmed dialysis (PD).. Case histories of 22 MM patients were analysed. They had a terminal stage of chronic renal failure (CRF) in the onset of the disease. Chemotherapy (CT) was performed in 20 patients (10 patients received VAD program, the other 10--melfalan).. Early lethality was 28%. The patients died of septic complications. Neutropenia was observed significantly more frequently on melfalan treatment than on VAD therapy (9 and 2 patients, respectively; chi-square 5.6; p = 0.009). Survival median, excluding early lethality, was 16 months. Differences by therapy were not registered. Three patients on MP program survived more than 3 years. Function of the kidneys improved in 4 (20%) patients. Hemodialysis was avoided in 2 patients. Survival of patients with reestablished renal function was maximal (44 and 84 months).. Standard CT for MM with terminal CRF is associated with high toxicity and frequent septic complications. Survival is better if renal function improves and HD discontinues. Reversibility of CRF at a terminal stage in MM does not depend on completeness of hematological response. Programs with melfalan CT provoke more frequent myelotoxic cytopenia, early lethality is higher but the number of longer survivals is more.

[Comparison of regimen-related toxicity between high-dose melphalan and ICE as a preparatory regimen for autologous stem cell transplantation].
    Gan to kagaku ryoho. Cancer & chemotherapy, 2007, Volume: 34, Issue:10

    Chemotherapy-susceptive multiple myeloma (MM) has an indication for high-dose melphalan (HDM) followed by autologous stem cell transplantation (auto-SCT). HDM was a most simple and convenient regimen among various preparatory regimens, because of rapid infusion divided over 2 days. In order to assess the potential of auto-SCT by HDM in a outpatient setting, we evaluated the toxicities of HDM compared with the ICE regimen generally applied to patients with refractory or relapsed lymphoma. We reviewed 27 cases of auto-SCT from April 2003 to December 2004. The preparatory regimen was HDM (melphalan 200 mg/m(2)) for 18 cases of multiple myeloma and ICE therapy (ifosfamide 12 g/m (2), carboplatin 1,200 mg/m(2), etoposide 800 mg/m2) for 9 malignant lymphomas. Gastrointestinal (GI) adverse events for a patient per hospital day were 0.93 for myeloma and 0.95 for lymphoma (no significant differences), with GI toxicity of more than grade 3, 0.08 and 0.12, respectively (p=0.07). Hematological toxicity was not significantly different between the 2 therapies. The clinical toxicity of HDM was milder compared to ICE, especially regarding the speculated GI-associated nutritional disorders. We thus concluded that outpatient auto-SCT could be validated first in myeloma patients treated by HDM with careful supportive treatments, thereby avoiding regimen-related severe adverse events.

Beta-2-microglobulin level predicts outcome following autologous hematopoietic stem cell transplantation in patients with multiple myeloma.
    Transplantation proceedings, 2007, Volume: 39, Issue:9

    Despite the widespread use of high-dose therapy combined with autologous hematopoietic stem cell transplantation (autoHSCT), the outcomes of multiple myeloma (MM) treatment remain variable. The aim of this study was to define pretransplantation factors that influence outcomes following autoHSCT in patients with MM. Eighty-one MM patients, aged 51 years (range 31-70 years), undergoing first autoHSCT were included in the analysis. Thirty patients were in complete remission and 51 were in partial remission. The conditioning regimen was based mainly on melphalan (200 mg/m(2) intravenous [iv]). The following factors were tested for their prognostic significance: beta-2-microglobulin (B2M), lactate dehydrogenase, monoclonal protein level, bone marrow plasma cell percentage (PL), hemoglobin level, age, interval from diagnosis to autoHSCT, and number of transplanted CD34-positive cells. The transplant-related mortality at day 100 was 3.7% (3/81). The incidence of progression at 9.2 years was 71% for patients with elevated B2M, and 32% for those where B2M was within normal limits (P = .02.) The probability of PFS was decreased for patients with B2M > or = versus < normal limits (29% vs 68%; P = .02) and PL > or = versus < 5% (0% vs 45%; P = 0.03). In a multivariate analysis B2M remained the only factor associated with increased risk of progression (relative risk [RR] = 3.3; P = .03) and reduced probability of PFS (RR = 3.3; P = .03). We concluded that B2M level measured at first autoHSCT was a useful predictor for progression and PFS in MM patients.

Autologous stem cell transplantation followed by consolidation chemotherapy for patients with multiple myeloma.
    Bone marrow transplantation, 2006, Volume: 37, Issue:1

    Although high-dose therapy and autologous stem cell transplant (ASCT) is superior to conventional chemotherapy for treatment of myeloma, most patients relapse and the time to relapse depends upon the initial prognostic factors. The administration of non-cross-resistant chemotherapies during the post-transplant period may delay or prevent relapse. We prospectively studied the role of consolidation chemotherapy (CC) after single autologous peripheral blood stem cell transplant (auto-PBSCT) in 103 mostly newly diagnosed myeloma patients (67 patients were < or =6 months from the initial treatment). Patients received conditioning with BCNU, melphalan+/-gemcitabine and auto-PBSCT followed by two cycles of the DCEP+/-G regimen (dexamethasone, cyclophosphamide, etoposide, cisplatin+/-gemcitabine) at 3 and 9 months post-transplant and alternating with two cycles of DPP regimen (dexamethasone, cisplatin, paclitaxel) at 6 and 12 months post-transplant. With a median follow-up of 61.2 months, the median event-free survival (EFS) and overall survival (OS) are 26 and 54.1 months, respectively. The 5-year EFS and OS are 23.1 and 42.5%, respectively. Overall, 51 (49.5%) patients finished all CC, suggesting that a major limitation of this approach is an inability to deliver all planned treatments. In order to improve results following autotransplantation, novel agents or immunologic approaches should be studied in the post-transplant setting.

Thyroid hormone and insulin-like growth factor-I in patients with multiple myeloma treated with melphalan and prednisone.
    Archives of medical research, 2006, Volume: 37, Issue:1

    The relationship between endocrine regulation and immune system has recently become the subject of intense investigations. The aim of this study was the comparative assessment of serum levels of selected hormones and insulin-like growth factor-I (IGF-I) in patients with multiple myeloma (MM) during applied therapy.. The levels of prolactin, hGH, TSH, fT3, fT4 and IGF-I in serum of 13 untreated patients with MM and in 16 healthy controls were determined. The patients were treated in cyclic courses with melphalan plus prednisone, and investigations were carried out in the first four courses of this therapy. The results were compared in the following manner: (1) at entry between studied MM group and healthy subjects, and (2) during the therapy intragroup-intracyclic comparisons were made in paired serum samples collected from patients before and after every therapeutic course.. At entry, significantly lower levels of TSH and fT3 were obtained in MM patients. The means remained within low normal reference range. Slightly increasing levels of TSH and fT3 during treatment with lower concentrations of these hormones after every therapeutic course and a statistically significant difference of fT3 level in the fourth therapy course were revealed. The levels of fT4 were within the normal reference values and showed a tendency to decrease during therapy with significant differences in the first therapeutic course. After the third and the fourth therapy courses, concentrations of IGF-I were statistically significantly higher than initially.. Euthyroid sick syndrome can exist in MM patients, and the therapy with melphalan plus prednisone is accompanied by slightly expressed serum changes of thyroid hormone concentrations and IGF-I levels.

The tumor kinetics of multiple myeloma following autologous stem cell transplantation as assessed by measuring serum-free light chains.
    Leukemia & lymphoma, 2006, Volume: 47, Issue:1

    In multiple myeloma, changes in serum-free immunoglobulin light chains (FLC) are a more rapid indicator of treatment response than intact immunoglobulin due to their shorter serum half-life. The present study analysed the changes in serum FLC after autologous peripheral blood stem cell transplantation (PBSCT) in 19 patients. The majority of myeloma patients (18 of 19) undergoing PBSCT had a rapid fall in FLC concentrations. In all 11 of 19 patients with raised tumor FLC, it fell within 48 h following high-dose melphalan. In patients with monoclonal intact immunoglobulin, the tumor FLC fell quicker (median half-life 4.3 days) than the monoclonal intact immunoglobulin (median half-life 14 days). FLC recovery occurred after (13 of 19) or around the time of neutrophil engraftment (6 of 19). With a median follow up of 220 days post-transplant, 16 of 19 patients have a normal FLC ratio and 3 of 19 have an elevated tumor FLC/abnormal ratio. FLC assays provided a sensitive monitor of changes in tumor and non-tumor plasma cells after PBSCT. This assay is potentially valuable as a marker of chemosensitivity, as an indicator of residual tumor and indicated time to lymphocyte engraftment. Further follow-up is required to ascertain whether differences in the kinetics of FLC responses have any prognostic clinical utility.

Prognostic relevance of CD56 expression in multiple myeloma: a study including 107 cases treated with high-dose melphalan-based chemotherapy and autologous stem cell transplant.
    Leukemia & lymphoma, 2006, Volume: 47, Issue:1

    CD56 is a neural adhesion molecule and expressed in 70-80% cases of multiple myeloma (MM). Lack of CD56 expression has shown to be a poor prognosis in MM patients treated with conventional chemotherapy, but its prognostic relevance in MM treated with high dose chemotherapy and autologous stem cell transplant (ASCT) is not known. CD56 expression was evaluated by immunohistochemistry on bone marrow paraffin embed specimens from 107 MM cases undergoing Melphalan-based high dose therapy and ASCT. CD56 was expressed by the myeloma cells in 71% of the patients. CD56 negative myeloma was associated with bone lesions (p = 0.032), but there was no association with any other biological or genetic risk factors including deletions 13q, p53 and IgH translocations, as evaluated by fluorescence in situ hybridization (FISH). There was no significant difference between CD56 positive and CD56 negative myeloma for progression free or overall survival (p = 0.28 and p = 0.67, respectively). In contrast to reports of CD56 in myeloma treated with conventional chemotherapy, CD56 negativity was not found to confer a poor prognosis in these patients, suggesting Melphalan-based high-dose chemotherapy and ASCT may overcome the adverse influence of CD56 negative myeloma.

High-dose idarubicin, busulphan and melphalan for autologous stem cell transplantation in multiple myeloma responsive to DAV chemotherapy: comparison with a historical control.
    Acta haematologica, 2006, Volume: 115, Issue:1-2

    Since 1997, 32 newly diagnosed multiple myeloma patients responsive to DAV chemotherapy were autografted with idarubicin-intensified busulphan-melphalan (ida-bu-mel). Main endpoints of the study were transplant-related toxicity, overall survival (OS) and progression-free survival (PFS). The results were compared with a historical control group of 38 patients treated with the 'standard' bu-mel regimen. Concerning time to engraftment, no significant difference was observed between the two groups, while toxicity was significantly higher in the intensive conditioning group, regarding grade IV mucositis, duration of profound neutropenia, incidence of infections and platelet requirement. Five-year OS and PFS are 73 versus 78% and 37 versus 48% for the intensive and standard regimen, respectively (p value not significant). The ida-bu-mel schedule appears to be a feasible and effective regimen for newly diagnosed multiple myeloma patients; nevertheless, no apparent benefit in OS and PFS arises from the comparison with a historical control treated with standard bu-mel, which is better tolerated and at least equally effective.

The role of second autografts in the management of myeloma at first relapse.
    Haematologica, 2006, Volume: 91, Issue:1

    We report an analysis of the value of a second high-dose melphalan autograft, performed at relapse, on a series of newly diagnosed myeloma patients entered into the high-dose program at our center. We conclude that relapse-free survival after the first autograft is a major prognostic factor in determining outcome.

Predictive factors for survival in myeloma patients who undergo autologous stem cell transplantation: a single-centre experience in 211 patients.
    Bone marrow transplantation, 2006, Volume: 37, Issue:8

    High-dose therapy with autologous stem cell therapy (ASCT) has become the treatment of choice for eligible patients with myeloma. We analysed retrospectively the prognostic influence of pre-transplant characteristics and transplant modalities on response and survival in 211 myeloma patients who were transplanted in our centre between 1994 and 2004. All patients received peripheral blood stem cell support after conditioning with melphalan alone (183 patients), or melphalan and total blood irradiation (28 patients). We evaluated the influence of age, type of multiple myeloma, status prior and post ASCT, previous treatment regimens, time of ASCT from diagnosis, year of autograft, dose of re-infused CD34(+) cells, plasma cell infiltration and beta2-microglobulin at diagnosis on overall survival (OS) and event-free survival (EFS) to define patients with better prognosis. Median OS and EFS from transplantation were 50.9 and 20.1 months, respectively. Median OS from diagnosis was 68.8 months. Transplant-related mortality was 1.4%. Lower beta2-microglobulin levels, achievement of complete remission (CR) post transplant and lower plasma cell infiltration at diagnosis and transplant correlated with longer EFS and OS, whereas CR at transplant and low international prognostic index at transplant correlated with better EFS. Higher CD34(+) cell dose correlated with improved OS. We conclude that ASCT is safe and effective and the outcome is independent of age, time from diagnosis, previous treatment and conditioning regimen.

Long-term complete remission in IgD-myeloma.
    European journal of haematology, 2006, Volume: 76, Issue:4

    Long-term complete remission in IgD multiple myeloma (MM) is rare. This case report describes a patient with a stage IIIB IgD-MM, who was treated with conventional melphalan and prednisone chemotherapy. The monoclonal protein disappeared after four cycles and therapy was discontinued after 14 cycles. Re-evaluation after a follow up of more than 8 years demonstrates a continuing complete remission suggesting a cure. This is remarkable, considering that several adverse prognostic factors were present. In addition a concise review on IgD-MM is given.

Prognostic factors in solitary plasmacytoma of the bone: a multicenter Rare Cancer Network study.
    BMC cancer, 2006, May-05, Volume: 6

    Solitary plasmacytoma (SP) of the bone is a rare plasma-cell neoplasm. There are no conclusive data in the literature on the optimal radiation therapy (RT) dose in SP. Therefore, in this large retrospective study, we wanted to assess the outcome, prognostic factors, and the optimal RT dose in patients with SP.. Data from 206 patients with bone SP without evidence of multiple myeloma (MM) were collected. Histopathological diagnosis was obtained for all patients. The majority (n = 169) of the patients received RT alone; 32 chemotherapy and RT, and 5 surgery. Median follow-up was 54 months (7-245).. Five-year overall survival, disease-free survival (DFS), and local control was 70%, 46%, and 88%; respectively. Median time to MM development was 21 months (2-135) with a 5-year probability of 51%. In multivariate analyses, favorable factors were younger age and tumor size < 5 cm for survival; younger age for DFS; anatomic localization (vertebra vs. other) for local control. Older age was the only predictor for MM. There was no dose-response relationship for doses 30 Gy or higher, even for larger tumors.. Younger patients, especially those with vertebral localization have the best outcome when treated with moderate-dose RT. Progression to MM remains the main problem. Further investigation should focus on adjuvant chemotherapy and/or novel therapeutic agents.

Derivative (1;7)(q10;p10) in multiple myeloma. A sign of therapy-related hidden myelodysplastic syndrome.
    Cancer genetics and cytogenetics, 2006, Volume: 167, Issue:2

    Therapy-related myelodysplastic syndrome (MDS) is a major problem in long-term cancer survivors, therefore early detection and prevention of therapy-related secondary neoplasia is an important issue. We searched for therapy-related MDS and analyzed cytogenetic changes in 155 patients with multiple myeloma (MM) from a single institution. Of the total 155 MM patients with cytogenetic results, 7 patients showed de novo appearance of myeloid-related cytogenetic changes, and 5/7 had -7/7q-, including 3 with der(1;7)(q10;p10): 3 patients developed MDS (i.e. 2 patients with der(1;7)(q10;p10) and 1 with a complex abnormality including -5 and 7q-). Among five patients receiving more than 2 g of melphalan, three developed MDS, and two of them showed der(1;7)(q10;p10) before or at the time of MDS diagnosis. Although morphologic identification of MDS was difficult in some cases, we concluded that the presence of 7q-, specifically der(1;7)(q10;p10), during chemotherapy involving melphalan for MM patients might indicate hidden MDS status and appropriate therapeutic options should be considered for such patients.

The histone deacetylase inhibitor LBH589 is a potent antimyeloma agent that overcomes drug resistance.
    Cancer research, 2006, Jun-01, Volume: 66, Issue:11

    Multiple myeloma represents an incurable disease, for which development of new therapies is required. Here, we report the effect on myeloma cells of LBH589, a new hydroxamic acid-derived histone deacetylase inhibitor. LBH589 was a potent antimyeloma agent (IC(50) < 40 nmol/L) on both cell lines and fresh cells from multiple myeloma patients, including cells resistant to conventional chemotherapeutic agents. In addition, LBH589 potentiated the action of drugs, such as bortezomib, dexamethasone, or melphalan. Using gene array, quantitative PCR, and Western analyses, we observed that LBH589 affected a large number of genes involved in cell cycle and cell death pathways. LBH589 blocked cell cycle progression, and this was accompanied by p21, p53, and p57 up-regulation. LBH589 induced cell death through an increase in the mitochondrial outer membrane permeability. LBH589 favored apoptosome formation by inducing cytochrome c release, Apaf-1 up-regulation, and caspase-9 cleavage. In addition, LBH589 stimulated a caspase-independent pathway through the release of AIF from the mitochondria. LBH589 down-regulated Bcl-2 and particularly Bcl-X. Moreover, overexpression of Bcl-X in multiple myeloma cells prevented LBH589-induced cell death. All these data indicate that LBH589 could be a useful drug for the treatment of multiple myeloma patients.

Preferential in vivo DNA repair of melphalan-induced damage in human genes is greatly affected by the local chromatin structure.
    DNA repair, 2006, Aug-13, Volume: 5, Issue:8

    To investigate the molecular mechanisms of action of the nitrogen mustard melphalan in patients treated for multiple myeloma, the in vivo induction and repair of melphalan-induced DNA damage was measured in genes with different transcriptional activity (b-actin>p53>N-ras>d-globin) from leukocytes of 20 multiple myeloma patients following chemotherapeutic administration of high-dose melphalan (200mg/m(2)) and autologous blood stem cell transplantation. Heterogeneous repair was found among the studied genes. The extent of repair was always in the order: b-actin>p53>N-ras>d-globin, correlating with the gene transcriptional state. Similar findings were obtained using peripheral blood mononuclear cells (PBMC) from healthy volunteers following in vitro treatment with melphalan, indicating that these results are not malignant disease-specific. Following in vitro treatment of PBMC from healthy volunteers with alpha-amanitin, an inhibitor of RNA polymerase II that can also induce condensation of chromatin structure, a significant inhibition of the removal of melphalan-induced damage in the three active genes but not in the silent d-globin gene was found, suggesting that transcription and/or chromatin structure may play important roles in the preferential DNA repair. When the in vivo DNA damage formation and repair in multiple myeloma patients following chemotherapeutic administration of melphalan was measured in the two strands of the active genes, no strand bias was found, indicating that the global genome repair subpathway of nucleotide excision repair may play a crucial role in the repair of these adducts. These results were also confirmed in PBMC from healthy volunteers following in vitro treatment with melphalan. Using micrococcal nuclease digestion of nuclei isolated from PBMC of multiple myeloma patients before the chemotherapeutic treatment, as well as from PBMC of healthy volunteers, we probed the chromatin structure in each gene and found that the "looseness" of the chromatin structure correlated with the levels of the gene-specific repair, being again in the order: b-actin>p53>N-ras>d-globin. To conclude, the in vivo gene-specific repair of melphalan-induced damage in humans is greatly affected by the local chromatin structure.

Epistaxis and severe weakness in a patient with multiple myeloma. Therapy-related acute myeloid leukemia, pure erythroid leukemia.
    Archives of pathology & laboratory medicine, 2006, Volume: 130, Issue:7

    Therapy-related acute myeloid leukemias arise as a result of cytotoxic chemotherapy and/or radiation therapy. The most common types of acute myeloid leukemia arising in this setting are acute myeloid leukemia with maturation, and lesser numbers of acute myelomonocytic leukemia, acute monocytic leukemia, acute erythroleukemia, or acute megakaryocytic leukemia. We present a patient with multiple myeloma who was treated with melphalan and 4 years later developed acute erythroid leukemia. The morphologic diagnosis of pure erythroid leukemia developing in the setting of multiple myeloma may be challenging.

[Plasmacytoma with multiple hypervascular lesions revealed by angiography in a patient with multiple myeloma].
    [Rinsho ketsueki] The Japanese journal of clinical hematology, 2006, Volume: 47, Issue:6

    A 68-year-old woman suffering from a left iliac tumor and severe back pain was admitted to another hospital in May 1999. The bone X-ray, CT scan and MRI demonstrated a 7 cm x 5 cm left iliac tumor with osteolysis and she was transferred to our hospital. Angiography demonstrated multiple hypervascular lesions in the left ilium, lumbar vertebrae, left ischium, left pubis and left rib. The tumor was resected and diagnosed as a plasmacytoma. Immunoelectrophoresis did not show any M-protein in the serum and urine, but the patient was diagnosed as having a non-secretory or low producing multiple myeloma because of the presence of 42.8% of abnormal plasma cells in the bone marrow aspirate. Her symptoms improved following 3 courses of MCNU-VMP therapy and the bone marrow plasma cells decreased to less than 5%. She was discharged and treated as an outpatient but relapsed and died of chemotherapy-resistant myeloma. We report this case because macro-angiogenesis in a multiple myeloma demonstrated by angiography is rare and interesting.

Didox, a ribonucleotide reductase inhibitor, induces apoptosis and inhibits DNA repair in multiple myeloma cells.
    British journal of haematology, 2006, Volume: 135, Issue:1

    Ribonucleotide reductase (RR) is the enzyme that catalyses the rate-limiting step in DNA synthesis, the production of deoxynucleotides. RR activity is markedly elevated in tumour tissue and is crucial for cell division. It is therefore an excellent target for cancer chemotherapy. This study examined the anti-myeloma activity of Didox (3,4-Dihydroxybenzohydroxamic acid), a novel RR inhibitor (RRI). Our data showed that Didox induced caspase-dependent multiple myeloma (MM) cell apoptosis. Didox, unlike other RRIs that mainly target the pyrimidine metabolism pathway, targets both purine and pyrimidine metabolism pathways in MM, as demonstrated by transcriptional profiling using the Affymetrix U133A 2.0 gene chip. Specifically, a >or=2-fold downregulation of genes in these anabolic pathways was shown as early as 12 h after exposure to Didox. Furthermore, apoptosis was accompanied by downregulation of bcl family proteins including bcl-2, bcl(xl), and XIAP. Importantly, RR M1 component transcript was also downregulated, associated with decreased protein expression. Genes involved in DNA repair mechanisms, specifically RAD 51 homologue, were also downregulated. As Didox acts on MM cells by inhibiting DNA synthesis and repair, combination studies with melphalan, an agent commonly used in MM, were performed. A strong in vitro synergism was shown, with combination indices of <0.7 as determined by the Chou-Talalay method. These studies therefore provide the preclinical rationale for evaluation of Didox, alone and in combination with DNA-damaging agents, to improve patient outcome in MM.

Thymoglobulin targets multiple plasma cell antigens and has in vitro and in vivo activity in multiple myeloma.
    Leukemia, 2006, Volume: 20, Issue:10

    Multiple myeloma is characterized by the proliferation of clonal plasma cells that have a heterogeneous expression of various cell surface markers, precluding successful use of monoclonal antibodies for therapeutic targeting of the tumor cell. Thymoglobulin (rabbit-derived polyclonal anti-thymocyte globulin), by virtue of its method of preparation, contains antibodies against several B-cell and plasma cell antigens and offers an attractive option for immunotherapy of myeloma. Here, we demonstrate potent anti-myeloma activity of the rabbit anti-thymocyte globulin preparation Thymoglobulin in vitro and in vivo in an animal model of myeloma. Thymoglobulin was able to induce dose- and time-dependent apoptosis of several myeloma cell lines, including those resistant to conventional anti-myeloma agents. Importantly, the anti-myeloma activity was preserved even when myeloma cells were grown with different cytokines demonstrating the ability to overcome microenvironment-mediated resistance. Thymoglobulin induced apoptosis of freshly isolated primary myeloma cells from patients. Using a competitive flow cytometric analysis, we were able to identify the potential antigen targets for Thymoglobulin preparation. Finally, in a plasmacytoma mouse model of myeloma, Thymoglobulin delayed the tumor growth in a dose-dependent manner providing convincing evidence for continued evaluation of this agent in the clinic in patients with myeloma, either alone or in combination with other agents.

MBL2 polymorphism and risk of severe infections in multiple myeloma patients receiving high-dose melphalan and autologous stem cell transplantation.
    Bone marrow transplantation, 2006, Volume: 38, Issue:8

    Severe infections related to treatment are common in patients with multiple myeloma (MM). Genetic polymorphisms of the immune system may influence the risk of infections. Mannan-binding lectin (MBL) is part of the innate immune system, and individuals homozygous for wild-type MBL encoding gene (MBL2) have a well-functioning MBL pathway of complement activation, in contrast to individuals carrying one or two variant alleles. We evaluated 113 courses of high-dose melphalan and autologous stem cell transplantation (ASCT) in patients with MM. Patients homozygous for wild-type MBL2 had a significantly reduced risk of septicaemia during the ASCT procedure compared with patients carrying variant MBL2: Odds Ratio (OR) 0.19 (95% CI: 0.04-0.77), (P=0.02) in multivariate analysis. The risk of Common Toxicity Criteria grade 3-4 infections in general was not affected by wild-type MBL2: OR 1.20 (95% CI: 0.52-2.78), (P=0.67). The findings indicate that MBL to some extent protects against the most severe infections during ASCT.

Oral mucositis in myeloma patients undergoing melphalan-based autologous stem cell transplantation: incidence, risk factors and a severity predictive model.
    Bone marrow transplantation, 2006, Volume: 38, Issue:7

    Melphalan-based autologous stem cell transplant (Mel-ASCT) is a standard therapy for multiple myeloma, but is associated with severe oral mucositis (OM). To identify predictors for severe OM, we studied 381 consecutive newly diagnosed myeloma patients who received Mel-ASCT. Melphalan was given at 200 mg/m2 body surface area (BSA), reduced to 140 mg/m2 for serum creatinine >3 mg/dl. Potential covariates included demographics, pre-transplant serum albumin and renal and liver function tests, and mg/kg melphalan dose received. The BSA dosing resulted in a wide range of melphalan doses given (2.4-6.2 mg/kg). OM developed in 75% of patients and was severe in 21%. Predictors of severe OM in multiple logistic regression analyses were high serum creatinine (odds ratio (OR)=1.581; 95% confidence interval (CI): 1.080-2.313; P=0.018) and high mg/kg melphalan (OR=1.595; 95% CI: 1.065-2.389; P=0.023). An OM prediction model was developed based on these variables. We concluded that BSA dosing of melphalan results in wide variations in the mg/kg dose, and that patients with renal dysfunction who are scheduled to receive a high mg/kg melphalan dose have the greatest risk for severe OM following Mel-ASCT. Pharmacogenomic and pharmacokinetic studies are needed to better understand interpatient variability of melphalan exposure and toxicity.

Recurrence of autoimmune disease after autologous peripheral blood stem cell transplantation for multiple myeloma.
    International journal of hematology, 2006, Volume: 84, Issue:4

    There have been a number of reports on the improvement of concomitant autoimmune disease (AID) after autologous hematopoietic stem cell transplantation (SCT) performed for hematologic malignancy. However, in some cases of hematologic malignancy with AID, exacerbation of AID after autologous SCT has been reported. We have treated 27 adults with multiple myeloma with single or tandem autologous SCT. After peripheral blood stem cells were collected and stored without CD34+ cell selection or T-cell depletion, all patients received melphalan (200 mg/m2) as a conditioning regimen. In 2 patients with a history of AID (one with rheumatoid arthritis [RA] and the other with bullous pemphigoid [BP]) and in 1 patient with Sjögren syndrome, AID recurred 7 to 12 months after autologous SCT. The RA and BP were in durable remission before SCT, and no Sjögren syndrome-related disease activity was clinically documented at the time of SCT. No progression of the myeloma was observed when the AIDs recurred. The patients required systemic steroid therapy for their AID, and successful control of the disease was achieved. Our experience suggests that autologous SCT with unmanipulated stem cells for myeloma is unlikely to cure preexisting AID; rather, the AID may worsen. Transplantation physicians should be aware of this possible complication.

Four-color flow cytometric analysis of myeloma plasma cells.
    American journal of clinical pathology, 2006, Volume: 126, Issue:6

    We monitored the behavior of residual myeloma plasma cells in patients with multiple myeloma after high-dose therapy and autologous or allogeneic transplantation using 3 methods of a flow cytometric technique using 4-color staining, immunofixation, and polymerase chain reaction approaches. We analyzed 17 cases by a relatively simple flow cytometric technique using CD38/CD45/CD19/CD56. Detectable myeloma plasma cells were found in 5 patients at diagnosis and 9 patients after treatment. Of 14 cases, 9 (64%) had CD19-CD56+ myeloma plasma cells, and 5 (36%) of 14 had CD19-CD56- myeloma plasma cells. When 37 bone marrow samples that had less than 5% myeloma plasma cells were assessed, myeloma plasma cells were detected in all 20 immunofixation-positive cases and 3 of 17 immunofixation-negative cases (P = .002). All 4 polymerase chain reaction-negative samples characterized as immunofixation-negative contained no detectable myeloma plasma cells. Flow cytometry can provide effective information to detect low levels of myeloma plasma cells.

Myelomatous pleural effusion.
    The Journal of the Association of Physicians of India, 2006, Volume: 54

    Serous effusions in multiple myeloma are uncommon but a myelomatous pleural effusion occurring in these patients is extremely rare. Here we report a rare case of a 38 years lady who was diagnosed to have multiple myeloma and subsequently developed pleural effusion. The myelomatous nature of the effusion was first diagnosed on cytology and subsequently confirmed by a pleural biopsy. The pleural effusion showed an initial response to chemotherapy but subsequently recurred.

Analysis of outcome following allogeneic haemopoietic stem cell transplantation for myeloma using myeloablative conditioning--evidence for a superior outcome using melphalan combined with total body irradiation.
    British journal of haematology, 2005, Volume: 128, Issue:4

    We have undertaken a retrospective multicentre analysis of 139 patients (median age 44.4 years) undergoing allogeneic haematopoietic stem cell transplantation (HSCT) for multiple myeloma using myeloablative conditioning. The majority of patients received total body irradiation (TBI) combined with either melphalan (56.9%) or cyclophosphamide (28.5%). Overall, transplant-related mortality (TRM) was 37.9% at 1 year and was not significantly different for patients receiving melphalan/TBI compared with cyclophosphamide/TBI. The overall complete remission (CR) rate, including patients in CR at the time of transplant, was greater for patients receiving melphalan/TBI (64.7%) compared with cyclophosphamide/TBI (47.2%)(P = 0.085). A significantly higher proportion of patients with continuing disease at the time of transplant achieved CR post-transplant following melphalan/TBI conditioning compared with cyclophosphamide/TBI (52.9% and 33.4% respectively, P = 0.009). Relapse/progression rates at 5 years were significantly lower for melphalan/TBI (36.7%) compared with cyclophosphamide/TBI (80.8%, P < 0.0001) and remained significant in multivariate analysis. This resulted in an overall survival at 5 years of 44.1% and 28.1% for melphalan/TBI and cyclophosphamide/TBI, respectively (P = 0.059). These results demonstrate that the type of conditioning for sibling allogeneic HSCT for myeloma has a major effect on transplant outcome.

The FA/BRCA pathway is involved in melphalan-induced DNA interstrand cross-link repair and accounts for melphalan resistance in multiple myeloma cells.
    Blood, 2005, Jul-15, Volume: 106, Issue:2

    Melphalan, a DNA cross-linker, is one of the most widely used and effective drugs in the treatment of multiple myeloma (MM). In this report, we demonstrate that enhanced interstrand cross-link (ICL) repair via the Fanconi anemia (FA)/BRCA pathway contributes to acquired drug resistance in melphalan-resistant myeloma cell lines, and disruption of this pathway reverses drug resistance. Using the alkaline comet assay (single-cell gel electrophoresis), we observed that melphalan-resistant cells have reduced ICL formation and enhanced ICL repair compared with melphalan-sensitive cells. Cell-cycle studies demonstrated that enhanced ICL repair released cells from melphalan-induced cell-cycle delay. Using siRNA to knock down FANCF in 8226/LR5 and U266/LR6 drug-resistant cells demonstrated a direct relationship between ICL repair capacity and drug sensitivity. Overexpression of FANCF in 8226/S and U266/S drug-sensitive cells partially reproduced the drug-resistant phenotype. These data show that enhanced DNA repair via the Fanconi anemia/BRCA pathway is involved in acquired melphalan resistance. Our findings provide for a new target to enhance response to DNA cross-linking agents in cancer treatment.

Melphalan 200 mg/m2 with blood stem cell support as first-line myeloma therapy: impact of glomerular filtration rate on engraftment, transplantation-related toxicity and survival.
    Bone marrow transplantation, 2005, Volume: 35, Issue:10

    In this retrospective single-centre study, 96 consecutive myeloma patients were treated with melphalan 200 mg/m(2) with blood stem cell support as first-line therapy. Their mean age was 55 (38-65) years. The impact of renal function on stem cell collection yield, engraftment, transplantation-related toxicity and overall survival was studied. Glomerular filtration rate (GFR) was evaluated by iohexol clearance, a median 32 days before high-dose administration. Chronic renal failure (GFR <60 ml/min) was present in 19 patients, with severe failure (GFR <30 ml/min) in five patients, including one patient on haemodialysis. No relationship between GFR and stem cell collection yield or engraftment was observed, nor was the incidence of neutropenic fever or infectious complications related to GFR. Patients with subnormal renal function, however, were more often affected by severe mucositis. In addition, the two patients with severe GI bleeding, the two pneumonia patients who needed ventilator support and the only therapy-related death were noted in the five patients with severe renal failure. Lower iohexol clearance at the time of high-dose administration was found to have a poor impact on survival. A reduction of melphalan dose in patients with severe renal failure, here defined as iohexol clearance <30 ml/min, is suggested.

Successful treatment of disseminated aspergillosis with the combination of voriconazole, caspofungin, granulocyte transfusions, and surgery followed by allogeneic blood stem cell transplantation in a patient with primary failure of an autologous stem cell
    European journal of haematology, 2005, Volume: 74, Issue:5

    The treatment of disseminated aspergillus infections in neutropenic patients remains a major challenge in spite of several new antifungal drugs. We report the case of a patient with multiple myeloma in prolonged neutropenia after primary failure of an autologous stem cell graft who developed invasive aspergillosis despite voriconazole monotherapy. He responded to a combination of voriconazole and caspofungin, supported by granulocyte transfusions and surgery. A subsequent allogeneic peripheral blood stem cell transplantation did not lead to recurring aspergillus infection. The patient is well and free of clinical disease with respect to the fungal infection and myeloma more than 18 months after the allogeneic transplantation.

Extent of damage and repair in the p53 tumor-suppressor gene after treatment of myeloma patients with high-dose melphalan and autologous blood stem-cell transplantation is individualized and may predict clinical outcome.
    Journal of clinical oncology : official journal of the American Society of Clinical Oncology, 2005, Jul-01, Volume: 23, Issue:19

    To quantitate the individual levels of melphalan-induced DNA damage formation and repair in vivo and to search for possible correlations with clinical outcome in patients with multiple myeloma (MM).. The formation and subsequent repair of DNA damage (monoadducts and interstrand cross-links) in the p53 tumor-suppressor gene, the proto-oncogene N-ras, and the housekeeping gene beta-actin during the first 24 hours after treatment with high-dose melphalan (HDM; 200 mg/m2) supported by autologous blood stem-cell transplantation (ABSCT) was measured in blood leukocytes of 26 patients with MM. The peak DNA adduct levels, the total amount of adducts over time, and the rate of adducts repair in each gene were correlated with response and time to progression after HDM.. The levels of gene-specific DNA damage formation and the individual repairing capacity varied up to 16-fold among patients, indicating that the melphalan-induced biologic effect in vivo is highly individualized. A significantly greater DNA damage and a slower rate of repair in p53 for all end points under study were found in patients who achieved tumor reduction compared with nonresponding patients. Furthermore, longer progression-free survival correlated with increased peak monoadduct levels in the p53 gene (P = .032).. Increased DNA damage and slower repairing capacity in the p53 gene from blood leukocytes after HDM correlate with improved outcome of patients with MM who undergo ABSCT. These results suggest that quantitation of such biologic end points may identify patients who are more likely to benefit from this procedure.

Long-term outcomes of previously untreated myeloma patients: responses to induction chemotherapy and high-dose melphalan incorporated within a risk stratification model can help to direct the use of novel treatments.
    British journal of haematology, 2005, Volume: 129, Issue:5

    Induction chemotherapy followed by high-dose melphalan (HDM) is the standard treatment for fitter patients with myeloma. The place of bortezomib and the thalidomide analogues within this treatment paradigm is yet to be established. We sought to identify patients who may benefit from the introduction of novel agents during their initial management. An intention-to-treat analysis was performed on 383 patients with newly diagnosed myeloma eligible for HDM to determine whether the extent of response to induction therapy and HDM correlated with long-term survival. Early response [complete response (CR) and partial response (PR)] to induction therapy was predictive of overall survival (OS) [median OS, 7.47 years for responders (CR and PR) versus 4.89 years for non-responders; P = 0.035]. The attainment of CR at 3 months post-HDM correlated with a prolonged progression-free survival (PFS) (median PFS, 7.4 years in CR group versus 5.3 years in non-CR group; P = 0.023). This data suggests that, at every stage of treatment, the aim should be to achieve CR. Patients with suboptimal responses could be offered alternative therapy. We propose a multiparametric risk-adapted model that includes response to induction chemotherapy and HDM, for identifying patients who may benefit from novel approaches to treatment.

Comparison between antithymocyte globulin and alemtuzumab and the possible impact of KIR-ligand mismatch after dose-reduced conditioning and unrelated stem cell transplantation in patients with multiple myeloma.
    British journal of haematology, 2005, Volume: 129, Issue:5

    We compared antithymocyte globulin (ATG) with alemtuzumab in 73 patients with multiple myeloma, who underwent reduced conditioning with melphalan/fludarabine, followed by allogeneic stem cell transplantation from human leucocyte antigen-matched or -mismatched unrelated donors. The ATG group had more prior high-dose chemotherapies (P < 0.001), while bone marrow was used more as the stem cell source in the alemtuzumab group (P < 0.001). Alemtuzumab resulted in faster engraftment of leucocytes (P = 0.03) and platelets (P = 0.02) and in a lower incidence of acute graft versus host disease (GvHD) grades II-IV (24% vs. 47%, P = 0.06). More cytomegalovirus (CMV) seropositive patients in the alemtuzumab group experienced CMV reactivation (100% vs. 47%, P = 0.001). The cumulative incidence of treatment-related mortality at 2 years was 26% [95% confidence interval (CI) = 12-37%] for ATG vs. 28% (95% CI = 15-55%) for alemtuzumab, P = 0.7. There was no significant difference in the estimated 2-year overall and progression-free survival between ATG and alemtuzumab: 54% (95% CI: 39-75%) vs. 45% (95% CI: 28-73%) and 30% (95% CI: 16-55%) vs. 36% (95% CI: 20-62%) respectively. In multivariate analysis, treatment with alemtuzumab had a higher risk for relapse (hazard ratio: 2.37; P = 0.05) while killer immunoglobulin-like receptor (KIR)-ligand mismatch was protective for relapse (P < 0.0001). We conclude that alemtuzumab produced less acute GvHD, but higher probability of relapse. The data implicated a major role of KIR-ligand mismatched transplantation in multiple myeloma.

Nongenotoxic activation of the p53 pathway as a therapeutic strategy for multiple myeloma.
    Blood, 2005, Nov-15, Volume: 106, Issue:10

    Mutation of p53 is a rare event in multiple myeloma, but it is unknown if p53 signaling is functional in myeloma cells, and if targeted nongenotoxic activation of the p53 pathway is sufficient to kill tumor cells. Here, we demonstrate that treatment of primary tumor samples with a small-molecule inhibitor of the p53-murine double minute 2 (MDM2) interaction increases the level of p53 and induces p53 targets and apoptotic cell death. Significantly, given the importance of the bone marrow microenvironment for the support and drug resistance of myeloma cells, tumor cells undergo effective apoptosis also in the presence of stromal cells, which themselves appear to tolerate exposure to nutlin-3. The in vitro toxicity of nutlin-3 was similar to that of the genotoxic drug melphalan. Because nutlin-mediated p53 activation is not dependent on DNA damage, MDM2 antagonists may help to avoid or reduce the severe genotoxic side effects of chemotherapeutic agents currently used to treat multiple myeloma. Therefore, MDM2 antagonists may offer a new treatment option for this disease.

Melphalan-induced apoptosis in multiple myeloma cells is associated with a cleavage of Mcl-1 and Bim and a decrease in the Mcl-1/Bim complex.
    Oncogene, 2005, Dec-01, Volume: 24, Issue:54

    Multiple myeloma (MM) is a rapidly fatal plasma-cell malignancy that evolves mainly in the bone marrow. Melphalan is widely used to treat patients with MM but as yet its mechanisms of action are poorly documented. In the current study, we demonstrate that melphalan induces a drastic downregulation of Mcl-1L, Bcl-x(L) and BimEL in human melphalan-sensitive myeloma cells while the most potent proapoptotic isoforms, BimL and S, are affected to a lesser extent. Moreover, Mcl-1L and BimEL disappearance is associated with the generation of proapoptotic cleaved forms generated by a caspase cleavage. In myeloma cells, we have previously shown that Mcl-1 neutralizes the proapoptotic function of Bim and therefore, prevents the activation of death effectors. In this study, we demonstrate that melphalan disrupts the Mcl-1/Bim complex whereas the Bcl-2/Bim complex is not modified. The disappearance of full length Mcl-1 allows the release of Bim isoforms, particularly L and S, which can exert their proapoptotic function and leads to Bax activation and cytochrome c release. Thus, we can hypothesize that the cleaved 26 kDa proapoptotic Mcl-1 and the 19 and 12 kDa of Bim, generated during melphalan treatment could contribute to the amplification loop of apoptosis.

Characterization of a R115777-resistant human multiple myeloma cell line with cross-resistance to PS-341.
    Clinical cancer research : an official journal of the American Association for Cancer Research, 2005, Aug-15, Volume: 11, Issue:16

    The farnesyl transferase inhibitor R115777 has been found to have clinical activity in diverse hematopoietic tumors. Clinical efficacy, however, does not correlate with Ras mutation status or inhibition of farnesyl transferase. To further elucidate the mechanisms by which R115777 induces apoptosis and to investigate drug resistance, we have identified and characterized a R115777-resistant human myeloma cell line. 8226/R5 cells were found to be at least 50 times more resistant to R115777 compared with the parent cell line 8226/S. K-Ras remained prenylated in both resistant and sensitive cells after R115777 treatment; however, HDJ-2 farnesylation was inhibited in both lines, implying that farnesyl transferase (the drug target) has not been mutated. Whereas many 8226 lines that acquire drug resistance have elevated expression of P-glycoprotein, we found that P-glycoprotein expression is not increased in the 8226/R5 line and intracellular accumulation of R115777 was not reduced. In fact, 8226/R5 cells were insensitive to a diverse group of antitumor agents including PS-341, and multidrug resistance did not correlate with the expression of heat shock proteins. Comparison of gene expression profiles between resistant and sensitive cells revealed expression changes in several genes involved in myeloma survival and drug resistance. Future experiments will attempt to identify genes that are directly linked to the resistant phenotype. Identification of molecules associated with R115777 and PS-341 resistance is clinically relevant because both compounds are being tested in solid tumors and hematopoietic malignancies.

Oral melphalan, prednisone, and thalidomide for newly diagnosed patients with myeloma.
    Cancer, 2005, Oct-01, Volume: 104, Issue:7

    Thalidomide is an immunomodulatory drug with strong antimyeloma activity. It is an effective treatment for multiple myeloma at disease recurrence and at diagnosis, both as a single agent and in combination with steroids or chemotherapy. No data are available on the association of thalidomide with oral melphalan and prednisone, still considered the standard treatment for elderly patients.. The feasibility and efficacy of the combination of melphalan, prednisone, and thalidomide (MPT) have been valuated in 49 newly diagnosed patients with multiple myeloma.. According to European Bone Marrow Transplantation/ International Bone Marrow Transplantation Registry (EBMT/IBMTR) criteria, 18% of patients achieved immunofixation-negative complete disease remission (CR), 6% achieved immunofixation-positive near CR, 4% achieved a very good partial response, and 45% achieved a partial response, with a 50-89% reduction in monoclonal paraprotein. Six percent did not respond and 10% showed progressive disease. The median time to maximum response was 4 months. The Kaplan-Meier estimates of event-free survival and overall survival at 2 years were 64% and 91%, respectively. The major acute adverse events (National Cancer Institute Common Toxicity Criteria Grade III-IV) included thrombosis (20%), infections (12%), constipation (6%), and hematologic (22%) and neurologic (8%) toxicities. One patient died of pulmonary thromboembolism.. These data suggested that MPT induced rapid and durable tumor responses with CR rates similar to those observed after autologous transplantation. Administration of prophylactic anticoagulant was required to prevent thromboembolism. MPT merits further investigation in randomized clinical trials.

Ifosfamide, epirubicin, etoposide (IEV) and autologous peripheral blood progenitor cell transplant: a feasible and effective salvage treatment for lymphoid malignancies.
    Oncology reports, 2005, Volume: 14, Issue:4

    The IEV schedule consisted of epirubicin 100 mg/m2 on day 1, etoposide 150 mg/m2 on days 1-3, and ifosfamide 2.5 g/m2 on days 1-3. Patients who proceeded to haematopoietic stem cell transplants (HDTs) received conditioning therapy with BEAM [for the Hodgkin's Lymphoma (HL) and non-Hodgkin's Lymphoma (NHL) groups], or melphalan 100 mg/m2 and mitoxantrone [for the multiple myeloma (MM) patients]. The study consisted of 65 patients with a median age of 53 years: 27 had aggressive NHL, 20 had HL, 7 had indolent NHL, and 11 had MM. Fifty-five patients received IEV for a disease that was refractory to conventional induction regimens, or that was in first or second relapse; 4 patients were treated with IEV while in complete response (CR) after chemotherapy in order to mobilise peripheral blood stem cells (PBSCs). Ninety percent of patients with HL responded to IEV, and 85% achieved CR. Both aggressive and indolent NHLs were less responsive (ORR 50 and 33%, respectively; CRR 41 and 16.5%, respectively). MM patients displayed an intermediate responsiveness (ORR 50% and CRR 30%). IEV was well tolerated in most patients. No life- threatening infections were recorded. PBSC mobilisation was successful in 37 out of 39 patients (95%) and led to the collection of a median of 16, 12, and 13.7 x 10(6) CD34+ cells/kg in patients with HL, NHL, and MM, respectively. All 37 patients underwent an autologous stem cell transplant following a 1 to 2 month interval after the end of IEV. Two patients were submitted to an allogeneic transplant. The median overall survival rate in HL, aggressive NHL, and indolent NHL is 32 (5-60), 16 (2-46), and 14 (4-42) months, respectively. Median EFS is 31 (5-60), 7 (2-46), and 7.5 (4-42) months, respectively. In conclusion, our study confirms that IEV +/- HDT is a well-tolerated and effective salvage treatment for lymphoid malignancies, and that IEV acts as an excellent stem cell mobiliser.

Re-use of the original infusional induction chemotherapy as salvage therapy in myeloma patients relapsing after one autograft.
    Hematology (Amsterdam, Netherlands), 2005, Volume: 10, Issue:5

    If standard infusional therapy (IC) has been used to treat myeloma at presentation, it is a matter of debate whether patients should receive the original induction therapy or a different drug combination in first relapse. Instinctively, most clinicians may switch treatment, particularly since the advent of new drugs for the treatment of myeloma. Hitherto, there has been no data on the efficacy of repeating standard IC in the salvage setting. We studied 62 myeloma patients whose initial treatment consisted of C-VAMP and a single high dose melphalan procedure and who were retreated with C-VAMP at the time of first relapse. Response to salvage C-VAMP was seen in 50% (95% confidence interval = 0.37-0.62) but we were unable to identify any predictors for response to salvage C-VAMP. Only patients resistant to salvage C-VAMP benefited from a second autograft. The survival of patients who responded to salvage C-VAMP was not prolonged by a second transplant. In conclusion, our data supports the use of C-VAMP for patients with myeloma in first relapse and suggest that only patients resistant to salvage C-VAMP should be offered a second autograft.

    The Annals of pharmacotherapy, 2005, Volume: 39, Issue:11

    To report thrombocytopenia in a patient prescribed thalidomide for multiple myeloma (MM).. A 70-year-old woman was diagnosed in 2003 with MM. At diagnosis, melphalan 0.25 mg/kg/day and prednisolone 2 mg/kg/day were started; however, the patient became refractory to therapy. Melphalan and prednisolone were discontinued, and monotherapy with dexamethasone 40 mg for 12 days per month was started. The patient's hematologic condition deteriorated again after about one year; dexamethasone was discontinued, and treatment with oral thalidomide 200 mg/day was initiated. About 2 weeks after thalidomide administration, the woman developed disabling adverse effects (flu-like symptoms, swollen fingers, rash and hematoma on her legs, shortness of breath, dry mouth, multiple petechiae). Laboratory testing showed neutropenia (neutrophils 0.4 x 10(9)/L) and thrombocytopenia (platelets 58 x 10(9)/L). Thalidomide was promptly discontinued; within 3 weeks, the laboratory values returned to pretreatment levels (1.3 x 10(9)/L and 267 x 10(9)/L, respectively) and her symptoms disappeared.. Thrombocytopenia is a rarely reported hematologic adverse consequence of thalidomide therapy. A recent report identified 5 patients who developed thrombocytopenia while undergoing monotherapy with thalidomide for MM. According to the Naranjo probability scale, thalidomide was classified as the probable cause of thrombocytopenia in our patient.. Unlike other antineoplastic drugs, thalidomide is rarely reported to cause severe hematologic toxicity. We present this case to increase clinicians' awareness for the potential of thalidomide to adversely affect platelet counts, particularly because its effectiveness in MM will likely result in expansion of its clinical use.

Factors useful for predicting survival of myeloma patients in everyday practice. A 10-year study of 148 patients older than 55 years.
    Joint bone spine, 2005, Volume: 72, Issue:6

    The objective of this study was to identify prognostic factors in a uniform population of older patients with myeloma.. Thirty-one study centers in France included 148 patients who were older than 55 years at diagnosis and were followed up until death or for at least 10 years. The following tests were available for all patients: blood cell counts; serum, and urinary protein electrophoresis; and serum levels of creatinine, calcium, beta2 microglobulin (beta2m), lactic dehydrogenase (LDH), and C-reactive protein (CRP).. Mean age was 71.9 years, median survival was 34 months, and mean survival was 47 months. In the univariate analysis, factors significantly associated with higher mortality were male gender (odds ratio [OR], 1-2.12), age older than 70 years (OR, 1.10-2.28), serum albumin<30 g/l (OR, 1.16-3.28), serum creatinine>100 micromol/l (OR, 1.34-2.81), beta2m>6 mg/l (OR, 1.78-4), CRP>6 mg/l (OR, 1.44-3.06), hemoglobin<10 g/dl (OR, 1.8-2.23). In the multivariate analysis, only two factors significantly predicted a higher risk of death: beta2m>6 mg/l (OR=2.439 [1.59-3.76]) and CRP>6 mg/l (OR=1.76 [1.18-2.63). beta2m level was >6 mg/l in 41 (27.7%) patients and CRP was >6 mg/l in 61 (43.6%) patients. Other potential prognostic factors such as chromosome 13 deletion were not investigated because they were not available for all study patients.. The strength of this study is the 10-year follow-up in a uniform patient cohort. beta2m and CRP independently predicted the risk of death.

Type III hyperlipoproteinemia with xanthomas and multiple myeloma.
    Journal of the American Academy of Dermatology, 2005, Volume: 53, Issue:5 Suppl 1

    Type III hyperlipoproteinemia usually results from an inherited defect in the composition of apolipoprotein E and is associated with atherosclerosis. An acquired form of the type III phenotype may rarely be associated with myeloma and immunoglobulin-lipoprotein complexes.. We present the case of a 72-year-old man with a history of well-controlled, unclassified hypercholesterolemia and hypertriglyceridemia, without evidence of atherosclerotic disease. He subsequently developed refractory dyslipidemia, palmar crease, and tuberous xanthomas. Type III hyperlipoproteinemia was confirmed, and nonclassic defective apolipoprotein E. Common secondary causes of hyperlipidemia were ruled out. A workup for malignancy revealed monoclonal IgA gammopathy. Immunostaining confirmed IgA antibodies complexed to the patient's very low-density lipoprotein (VLDL) fraction, causing gross impairment of VLDL metabolism. Conventional therapy for type III hyperlipoproteinemia was attempted but ineffective. Thus, chemotherapy was initiated for his myeloma, with subsequent lowering of his IgA, cholesterol, and triglyceride levels, and improvement of his xanthomas.. There are several unusual features to this case. Planar xanthomas can be associated with myelomas, but usually in the setting of normal lipids. Type III hyperlipoproteinemias are not usually refractory to standard therapy and are only rarely associated with IgA myeloma. IgA antibodies complexed to the patient's VLDL caused gross impairment of VLDL metabolism. The patient's apolipoprotein E genotype (heterozygote E2/E3) is not typical for expression of the heritable type III phenotype (homozygote E2/E2). These features support a causal relationship between this patient's multiple myeloma and type III hyperlipoproteinemia rather than two independent, coexistent conditions.

Plasma cell leukemia: case report of a rare and aggressive variant of multiple myeloma.
    JPMA. The Journal of the Pakistan Medical Association, 2005, Volume: 55, Issue:10

    Plasma cell leukemia (PCL) is a rare disease and is the least common variant of multiple myeloma accounting for 2-3% of all plasma cell dyscrasias. We report a patient who presented with history of high grade fever, weakness, palpitations, loss of appetite, bone pains and mental confusion for twenty days. Initial evaluation revealed plasmacytosis with blood plasma cell count of 5184/cumm. His hemoglobin (Hb) was 11.3 gm/dl, platelets were 75000/cumm and total leucocyte count (TLC) was 21600/cumm (24% plasma cells). Bone marrow examination revealed >60% plasmablasts. Serum LDH was high at 3117 U/L and serum calcium was also elevated at 13.9 mg/dl. A diagnosis of PCL was made and the patient was started on treatment for hypercalcaemia with Melphalan/Prednisolone regime along with supportive care. Patient deteriorated very rapidly despite treatment and died on the eighth day. A detailed report of this case and a review of PCL is presented here.

Feasibility and outcome of tandem stem cell autotransplants in multiple myeloma.
    Haematologica, 2005, Volume: 90, Issue:12

    Clinical trials have shown that high dose chemotherapy (HDT) with peripheral stem cell autotransplantation is presently the best treatment for patients with symptomatic multiple myeloma (MM). In the context of an outcomes research project, we analyzed the feasibility of this strategy in clinical practice in a large cohort of consecutive, unselected patients with newly diagnosed MM and looked at the major determinants of response of patients enrolled in a HDT with tandem autotransplantation (Total Therapy I, TTI) program.. Two hundred and fourteen patients were treated outside of a clinical trial and regularly followed-up at our Center for symptomatic MM. Ninety-seven patients (45%) received conventional chemo-radiotherapy regimens, 110 (51%) entered the TTI program and the remaining 7 patients (3.3%) were enrolled in other programs involving HDT with autotransplantation.. Patients enrolled in HDT with tandem autotransplantation programs were 14 years younger and less likely to have co-morbidities than patients treated with conventional therapy. Median overall survivals of the two groups were 60 and 33 months, respectively. Thirteen percent of the patients enrolled in the TTI program did not receive the first HDT with autotransplantation, mostly because of disease progression, and another 16% did not proceed to the second HDT with autotransplantation mainly because of infections or drug-related complications. Most patients achieved complete remission after the second autotransplantation, with acceptable toxicity. However, only patients with a major reduction of the myeloma burden at the end of induction therapy enjoyed significantly prolonged event-free and overall survivals.. Approximately one third of patients with newly diagnosed symptomatic MM completed the TTI program. These data suggest the need to improve the induction therapy in order to increase both the number of patients able to proceed to autotransplantation programs and to enhance the rate of early response.

Bortezomib-induced Sweet's syndrome.
    Haematologica, 2005, Volume: 90, Issue:12 Suppl

    Sweet's syndrome is an uncommon acute skin disease, associated with a variety of medical problems. The drug-induced variant is even rarer. We describe two cases of this syndrome associated with the administration of the proteasome inhibitor bortezomib. The diagnostic criteria for drug-induced Sweet's syndrome as proposed by Walker and Cohen were fulfilled. Vasculitis and neutrophilic eccrine hidradenitis were excluded.

Development of leukocytoclastic vasculitis in a patient with multiple myeloma during treatment with thalidomide.
    Annals of hematology, 2004, Volume: 83, Issue:7

    Thalidomide, an agent with antiangiogenic and immunomodulatory properties, is therapeutically effective in multiple myeloma, leprosy, and autoimmune diseases. The most common clinical toxicities of thalidomide are constipation, neuropathy, fatigue, sedation, rash, tremor, and edema. We here describe for the first time a patient who developed leukocytoclastic vasculitis during therapy with thalidomide. Of the 260 patients treated with thalidomide in our institution, this is the first patient who developed autoimmune disease. We conclude that patients with malignant disorders who are treated with thalidomide should be carefully monitored for the development of autoimmune disorders. Whether autoimmune phenomena also occur during treatment with new drugs such as PS-341 or potent immunomodulatory agents remains to be evaluated.

Interleukin-18 in multiple myeloma patients: serum levels in relation to response to treatment and survival.
    Leukemia research, 2004, Volume: 28, Issue:3

    Interleukin-18 (IL-18) plays a role in the host's response to tumours and angiogenesis. We determined serum levels of IL-18, vascular endothelial growth factor (VEGF), angiogenin (ANG), tumor necrosis factor (TNF-alpha) and CRP in 65 newly diagnosed myeloma patients. IL-18, VEGF, angiogenin, TNF-alpha and CRP were significantly higher at stage III in comparison to stages II and I. These cytokines (measured in 27 patients) significantly decreased after treatment. In survival analysis, higher levels of IL-18 were associated with a poorer prognosis. We conclude that increased serum IL-18 in myeloma patients correlates with advanced disease, increased levels of angiogenic cytokines and worse survival.

Dialysis-dependent renal failure in patients with myeloma can be reversed by high-dose myeloablative therapy and autotransplant.
    Bone marrow transplantation, 2004, Volume: 33, Issue:8

    To evaluate the role of high-dose melphalan and autologous transplant (AT) in reversing dialysis-dependent renal failure, 59 patients still on dialysis at the time of AT were analyzed. A total of 37 patients had been on dialysis < or =6 months. A 5-year event-free and overall survival rate of all patients after AT was 24 and 36%, respectively. Of 54 patients evaluable for renal function improvement, 13 (24%) became dialysis independent at a median of 4 months after AT (range: 1-16). Dialysis duration < or =6 months prior to first AT and pre-transplant creatinine clearance >10 ml/min were significant for renal function recovery: 12 of 36 (33%) < or =6 months vs one of 18 patients (6%) >6 months on dialysis recovered renal function; 10 of 26 (38%) with >10 ml/min vs three of 28 (11%) with < or =10 ml/min of creatinine clearance (both P<0.05). Quality of response after autotransplant was also significant: 12 of 31 (39%) being greater than partial remission after AT vs one of 21 patients (5%) attaining partial remission or less became independent of dialysis (P<0.05). Our data suggest that significant renal failure can be reversible and AT should be considered early in the disease course.

Multiple myeloma presenting with widespread osteosclerotic lesions.
    Joint bone spine, 2004, Volume: 71, Issue:1

    Sclerotic lesions are rare in malignant monoclonal gammopathies, although they are occasionally associated with POEMS syndrome (polyneuropathy, organomegaly, endocrinopathy, monoclonal gammopathy and skin changes). In most cases, osseous lesions in POEMS syndrome present as an isolated sclerotic deposit or a combination of both lytic and sclerotic lesions. Diffuse osteosclerosis is extremely rare and may lead to the diagnosis of multiple myeloma, classically known to present as lytic lesions in the skeleton, with or without diffuse osteoporosis. We report a 74-year-old woman with widespread and substantial osteosclerotic lesions, associated with IgA-lambda myeloma, and with no other criteria for POEMS syndrome, and who was rapidly diagnosed with compression of the spinal cord. Detailed knowledge of imaging features in myeloma emphasises the need to consider plasma cell neoplasm in the differential diagnosis of any pattern of bone sclerosis. Although exceptional, multiple myeloma must be borne in mind in the presence of diffuse bone sclerosis.

Interpretation of quality of life scores in multiple myeloma by comparison with a reference population and assessment of the clinical importance of score differences.
    European journal of haematology, 2004, Volume: 72, Issue:3

    Without clear guidelines, clinicians and health care providers are often uncertain how to interpret (quality of life) QOL scores. To facilitate the interpretation, QOL scores of multiple myeloma patients at diagnosis were compared with the scores of a reference population, and the clinical significance of QOL score differences and of changes in scores over time was assessed.. Data from two prospective Nordic Myeloma Study Group trials (221 patients <60 yr treated with high dose chemotherapy, and 203 patients >60 yr treated with melphalan and prednisone) were analysed. The EORTC QLQ-C30 questionnaire was used. The results were compared with the scores of an age- and gender-adjusted Norwegian reference population (n = 3000), using a regressional approach. The magnitude of the observed differences and of score changes during follow-up was estimated as effect size [score difference (SD)] and according to a subjective rating system as small, moderate or large.. At diagnosis, the most distressing problems were pain and fatigue, reduced physical functioning, limitations in role functioning and reduced overall QOL. These differences from the reference population were statistically significant (P < 0.001), and large or moderate according to the rating systems. After the start of treatment, small to moderate improvement in mean QOL scores were observed for most domains.. Comparison with a reference population eases the interpretation of QOL scores and prevents overestimation of symptoms and underestimation of subjective treatment response. The agreement between the two methods to evaluate the meaning of differences and changes in QOL scores was good.

Melphalan versus melphalan plus busulphan in conditioning to autologous stem cell transplantation for low-risk multiple myeloma.
    The hematology journal : the official journal of the European Haematology Association, 2004, Volume: 5, Issue:2

    High-dose chemotherapy conditioning regimens for autologous stem cell transplantation generally give similar results in multiple myeloma. We compared two regimens: melphalan versus melphalan plus busulphan.. In all, 30 untreated patients with stage III low-risk multiple myeloma were studied. After induction with three VAD courses and mobilization with cyclophosphamide 7 g/m(2) and recombinant human granulocyte-colony stimulating factor (rHuG-CSF) (10 microg/kg b.w./die), they received melphalan 200 mg/m(2) (arm A) or busulphan 16 mg/kg plus melphalan 100 mg/m(2) (arm B) for conditioning for transplantation. All patients received maintenance therapy with Interferon 3 MU x 3/week.. Time to engraftment after transplantation was similar in both groups. All patients received rHuG-CSF after reinfusion of peripheral stem cells. No differences emerged in transplant-related infective and noninfective complications. There were no transplant-related deaths. A better response was observed in the melphalan plus busulphan regimen (85 versus 75%, P<0.05). The 5-year overall survival with this regimen was 56 versus 49% with melphalan, and the median survival was 126 months versus 108 months for melphalan (P=0.7). The median progression-free survival was 121 months for melphalan plus busulphan versus 97 months for melphalan (P=0.05).. These two conditioning regimens showed similar overall response rate and overall survival, though progression-free survival was better with busulphan plus melphalan.

Serum syndecan-1, basic fibroblast growth factor and osteoprotegerin in myeloma patients at diagnosis and during the course of the disease.
    European journal of haematology, 2004, Volume: 72, Issue:4

    Neovascularisation and bone resorption are related to myeloma disease activity.. To investigate the possible prognostic importance of serum syndecan-1, basic fibroblast growth factor (bFGF) and osteoprotegerin (OPG) levels, the relationship between them, with parameters of disease activity and the effect of treatment on their levels.. Twenty-seven patients were studied from diagnosis and an additional five from remission, for a median follow-up of 40 months. Twenty-three patients received chemotherapy plus bisphosphonates and nine only bisphosphonates. Sera from 11 healthy individuals (HI) were used as controls. Cytokines were determined by commercially available enzyme-linked immunosorbent assays (ELISA) kits.. In HI, median syndecan-1 was 40 ng/mL (28-75), bFGF 8 pg/mL (7-30), OPG 35 pg/mL (4-100). Pretreatment median serum syndecan-1 was 177.5 ng/mL (34-3500), bFGF 11.5 pg/mL (8-65) and OPG 100 pg/mL (4-1000). Pretreatment syndecan-1, bFGF and OPG serum levels were increased in patients compared with HI (P = 0.001, 0.03 and 0.01, respectively). Syndecan-1 and bFGF levels were correlated with stage (P = 0.004 and 0.03, respectively). Both syndecan-1 and OPG levels were correlated with beta2M (P = 0.04 and 0.01, respectively). Patients with elevated syndecan-1 and bFGF serum levels had shorter survival than patients with normal levels (P = 0.01 and 0.05, respectively). After chemotherapy syndecan-1 and OPG levels were found to be decreased in responders and syndecan-1 level was reduced in patients receiving bisphosphonates alone.. Pretreatment syndecan-1, bFGF and OPG levels were found to be increased at diagnosis. Syndecan-1 and OPG fluctuated according to MM activity. Elevated serum syndecan-1 and bFGF levels predicted short survival.

Co-administration of simvastatin and cytotoxic drugs is advantageous in myeloma cell lines.
    Anti-cancer drugs, 2004, Volume: 15, Issue:1

    We have evaluated the potential application of simvastatin (Sim) combined with conventional cytotoxic drugs for the treatment of multiple myeloma. RPMI 8226 and U266 myeloma cells seeded in culture plates were treated with Sim (5 and 10 microM, respectively) combined with melphalan (Mel; 25 and 20 microM, respectively) or dexamethasone (Dex; 1 microM). We assessed cell cycle (propidium iodide staining and flow cytometric analysis), cell morphology, viability (WST1), total cell count and cell death (Trypan blue exclusion). Sim significantly enhanced the anti-myeloma activity of cytotoxic agents in vitro (p<0.05). Incubation of U266 and RPMI 8226 with Sim prior to Mel increased the cytotoxicity in an additive manner, whereas the exposure of U266 to combined Sim and Dex resulted in a synergistic amplification of the individual effects. Combined application of Dex and Sim to RPMI 8226 cells resulted in antagonistic activity. The possible roles of Ras and phosphoinositol 3-kinase are discussed.

    We observed a 73-year-old man with necrobiotic xanthogranuloma (NXG) on the eyelids and concurrent multiple myeloma. The treatment was surgery followed by administration of melphalan. No relapse was seen in 19 months of follow-up. We consider that surgical removal of xanthogranuloma is an advisable rapid treatment that involves fewer side-effects than other treatments.

[Multiple myeloma and HIV infection: report of 3 cases].
    Revue medicale de Liege, 2004, Volume: 59, Issue:2

    HIV infection rages at the endemic state in Sub Saharan African and especially in Congo Brazzaville. We report the observation of three female patients infected with HIV and developing multiple myeloma. The three patients were treated at the University hospital of Brazzaville between 2000 and 2002. In two cases multiple myeloma was discovered after the diagnosis of HIV infection. In the other case, the diagnosis of HIV infection was posterior to the occurrence of multiple myeloma. HIV infection was symptomatic in two cases who received consequently antiviral treatment. Multiple myeloma was diagnosed at an advanced stage in the three cases. The paraprotein was an IgG in two cases and an IgA in the other one. The CD4 counts before treatment were around 200/mm3 in two cases and within normal limits in the third case. Viral load was not measured. VMCP and VAMCP regimens were administered without major complications and under anti-infectious prophylaxis. The follow-up is still insufficient to assess the medium-term evolution and to determine the prognosis of multiple myeloma. The description of these three cases confirms the involvement of HIV in B cell lymphoma genesis.

Patients with CD45 negative multiple myeloma receiving high-dose therapy have a shorter survival than those with CD45 positive multiple myeloma.
    Haematologica, 2004, Volume: 89, Issue:5

    CD45 is a critical regulator of signaling threshold in immune cells. There are clinical and animal studies suggesting that the CD45-negative phenotype is the phenotype of progressive multiple myeloma (MM). The aims of this study were to confirm this hypothesis and to test the prognostic value of CD45 expression in newly diagnosed MM patients.. In a retrospective study of 95 newly diagnosed MM patients treated with high dose therapy we used 4-color flow cytometry to determine CD45 expression and correlated the immunophenotipic data with clinical data.. Thirty of 95 patients (31.5%) lacked CD45 expression at diagnosis. The CD45 phenotype significantly affected the overall survival (OS) of the patients, like the most common presenting prognostic parameters analyzed including b-2-microglobulin, age and 14q32 translocations. CD45 negative MM patients had a significantly worse OS than did CD45 positive cases of MM: 28.7% cumulative survival at 4 years, median 42 months vs not reached; p = 0.004. Furthermore, CD45 remained the only parameter adversely affecting OS in multivariate analysis.. The CD45 negative phenotype could reflect the phenotype of progressive disease in relation to the intrinsic malignancy of the MM clone. Indeed, CD45 negative myeloma cells appear to have a greater capacity to circulate, disseminate and clone as well as being less sensitive to apoptosis.

Anti-alpha4 integrin antibody suppresses the development of multiple myeloma and associated osteoclastic osteolysis.
    Blood, 2004, Oct-01, Volume: 104, Issue:7

    Supporting roles of stromal cells in preferential colonization of myeloma cells in bone marrow and development of associated osteoclastic osteolysis through cell-cell interactions have been indicated. Here we examined the effects of a monoclonal antibody to alpha4 integrin (anti-alpha4 Ab) that disrupts myeloma cell-stromal cell interactions mediated via alpha4beta1 integrin and vascular cell adhesion molecule-1 (VCAM-1) on myeloma cell growth in bone marrow and accompanying osteolysis. The anti-alpha4 Ab decreased VCAM-1-stimulated 5TGM1/luc cell growth in culture. The 5TGM1 murine myeloma cells stably transfected with the firefly luciferase (5TGM1/luc) were inoculated from tail vein in bg/xid/nd mice. Preventative administration of the anti-alpha4 Ab suppressed the elevation of serum IgG2b levels, decreased 5TGM1/luc tumor burden with increased apoptosis in bone and spleen, reduced bone destruction with diminished number of osteoclasts, and prolonged survival of 5TGM1/luc-bearing mice. In contrast, therapeutic administration of the antibody failed to show these effects. However, therapeutic administration of the antibody combined with melphalan significantly suppressed serum IgG2b levels and tumor burden in bone. Our results suggest that the interactions with stromal cells via alpha4beta1/VCAM-1 are critical to the development of myeloma and associated osteolysis and that disruption of these interactions using anti-alpha4 Ab is a potential therapeutic approach for myeloma.

Thrombotic microangiopathy (TMA) and stroke due to human herpesvirus-6 (HHV-6) reactivation in an adult receiving high-dose melphalan with autologous peripheral stem cell transplantation.
    American journal of hematology, 2004, Volume: 76, Issue:2

    We report an adult autologous stem cell transplant (ASCT) patient who developed transplant-associated thrombotic microangiopathy (TMA) due to human herpesvirus-6 (HHV-6) reactivation. A 58-year-old female with Stage IIIA IgGkappa multiple myeloma received a melphalan (200 mg/m2) ASCT with discharge home after resolution of ASCT-related toxicities. She presented on D+20 with dyspnea, rash, and fever to 105 degrees F, followed by worsening dyspnea, hypotension, and capillary leak. Mental status (MS) changes were noted on D+23, but head CT and EEG were unremarkable. On D+29, a generalized seizure occurred with decline in platelet count and haptoglobin. TMA was noted on peripheral blood smear and therapeutic plasma exchange (TPE) was initiated on D+31. Lumbar puncture (LP) revealed CSF protein 74 mg/dL and white blood count 7,000/mm3 with 74% lymphocytosis. TPE was continued without improvement in her MS or thrombocytopenia despite improvement in microangiopathy. An MRI of the brain showed a left hippocampus abnormality, and an EEG was consistent with encephalopathy. Serum polymerase chain regimen (PCR) was negative for CMV, HSV1, and HSV2 but was strongly positive for HHV-6. Repeat LP protein was 597 mg/dL. Foscarnet was initiated, and cerebrospinal fluid (CSF) PCR for HHV-6 revealed 1,400 DNA copies/mL. Her MS greatly improved within 48 hr of antiviral therapy, serum HHV-6 became negative, and TPE was tapered without recurrence of her TMA. TMA with HHV-6 reactivation is likely an underdiagnosed entity. Given its fulminant course and favorable response to therapy, HHV-6 reactivation should be considered a potential etiology in patients with TMA after ASCT.

Deletion of 5q31 and 7q31 in patients with stable melphalan treated multiple myeloma.
    Cancer genetics and cytogenetics, 2004, Jul-01, Volume: 152, Issue:1

    Multiple myeloma represents a malignant proliferation of plasma cells derived from a single clone. It is well known that alkylating agents are capable of inducing myelodysplastic syndromes (MDS) and acute myelocytic leukemias (AML). This risk of both diseases in patients with multiple myeloma has been estimated to be 10-20% after 10 years. We aimed to evaluate the time course and the type of genetic abnormalities in melphalan-treated patients in the chronic stage of the disease. We applied fluorescence in situ hybridization methods with probes to 5q31 and 7q31 to mononuclear peripheral blood leukocytes of 18 melphalan-treated patients and compared the results to those of 8 untreated myeloma patients. We found three patients (17%) with a 5q31 deletion in their peripheral white blood cells, but no 7q31 deletion. These findings suggest that 5q- occurs before the overt development of MDS/AML and raise important concerns regarding long-term treatment of myeloma patients with alkylating agents. Also, the performance of cytogenetic evaluation should be considered before autologous transplantation. The clinical and biological implications of these findings should be evaluated in larger clinical and laboratory studies.

Comparison of high-dose melphalan with a more intensive regimen of thiotepa, busulfan, and cyclophosphamide for patients with multiple myeloma.
    Cancer, 2004, Jun-15, Volume: 100, Issue:12

    High-dose chemotherapy (HDC) with autologous stem cell transplantation (ASCT) as part of the initial treatment regimen improves progression-free survival (PFS) and overall survival (OS) for patients with multiple myeloma. The optimal preparative regimen for patients with multiple myeloma has yet to be defined. In the current study, the authors compared the outcomes associated with high-dose melphalan (HDM) and a more intensive regimen of thiotepa, busulfan, and cyclophosphamide (TBC) in patients with multiple myeloma.. One hundred eighty-six patients with newly diagnosed multiple myeloma (median age, 51 years) received HDC with ASCT for consolidation of first remission (n = 108) or for treatment of primary refractory disease (n = 78). Seventy patients had a large tumor mass at the time of diagnosis. The preparative regimen consisted of TBC for 97 patients and HDM for 89 patients. Patients in the TBC group were younger and had more advanced disease stage at diagnosis and at the time of ASCT compared with patients in the HDM group.. The response rates (complete response [CR] and partial response [PR]) were similar in the TBC group (overall response rate, 66%; CR rate, 17%; PR rate, 49%) and the HDM group (overall response rate, 69%; CR rate, 28%; PR rate, 41%). PFS and OS were similar in both groups. A proportional hazards regression model revealed that Durie-Salmon disease stage at diagnosis and having received three or more previous treatment regimens were the only factors that predicted PFS; the type of preparative regimen did not influence outcome.. The results of the current study indicate that the use of a more intensive regimen did not improve results compared with HDM in patients with multiple myeloma. HDM should continue to be considered the standard preparative regimen for patients with myeloma.

Overexpression of PDZK1 within the 1q12-q22 amplicon is likely to be associated with drug-resistance phenotype in multiple myeloma.
    The American journal of pathology, 2004, Volume: 165, Issue:1

    We investigated DNA copy number aberrations in 37 cell lines derived from multiple myelomas (MMs) using comparative genomic hybridization, and 11 (29.7%) showed high-level gain indicative of gene amplification at 1q12-q22. A corresponding transcriptional mapping using oligonucleotide arrays extracted three up-regulated genes (IRTA2, PDZK1, and S100A6) within the smallest region of overlapping in amplifications. Among them PDZK1 showed amplification and consequent overexpression in the MM cell lines. Amplification of PDZK1 was observed in primary cases of MM as well. MM cell lines with amplification of PDZK1 exhibited the resistance to melphalan-, cis-platin-, and vincristin-induced cell death compared with MM cell lines without its amplifications. Furthermore, down-regulation of PDZK1 with an anti-sense oligonucleotide sensitized a cell line KMS-11 to melphalan, cis-platin, and vincristin. Taken together, our results indicate that PDZK1 is likely to be one of targets for 1q12-q22 amplification in MM and may be associated with the malignant phenotype, including drug resistance, in this type of tumor.

A rare case of interstitial pneumonitis after tandem high-dose melphalan conditioning and autologous stem cell transplantation in multiple myeloma.
    European journal of haematology, 2004, Volume: 73, Issue:2

    A 57-yr-old woman with multiple myeloma received an autologous tandem transplant at a 4-month interval. She was conditioned twice with 225 mg/m2 melphalan. After the second transplant, interstitial pneumonitis (IP) ensued. The clinical course was life threatening and mechanical ventilation was required for 32 d. All attempts to identify an infectious agent failed. A presumptive diagnosis of idiopathic IP, possibly related to melphalan toxicity, was made. High-dose methylprednisolone administration led to rapid and durable improvement. Melphalan was employed for conditioning in the tandem setting with an interval of only 3-4 months between two courses or a dose elevation to 225 instead of 200 mg/m2, may have induced IP which responded favorably to methylprednisolone.

[Multiple myeloma of the IgD-lambda type invading CNS].
    [Rinsho ketsueki] The Japanese journal of clinical hematology, 2004, Volume: 45, Issue:10

    A 52-year-old woman was admitted to the gynecological department of our hospital on July 29, 2002 because of a right lower abdominal mass. She has been suffering from pain in the right leg and inguinal area for a month before coming to the hospital. She was found to have pancytopenia and high serum levels of LDH and IgD. A bone marrow examination showed 63.8% of plasma cells and serum immunoelectrophoresis showed M-protein of the IgD-lambda type. She was diagnosed as having multiple myeloma and transferred to our department. VAD therapy was started from August 22. Although the plasma cells in the bone marrow almost disappeared, the right lower abdominal mass remained and a new mass appeared on the right frontal chest wall after two courses of the treatment. Combination chemotherapy with vincristine, ranimustine, melphalan, and dexamethasone (ROAD) was started on November 1. This was followed with thalidomide and radiation therapy of the right inguinal region was added. On December 16th, she suddenly experienced speech disturbance, nausea and the disturbance of consciousness. Examination of her cerebrospinal fluid showed 368/microl mononuclear cells with 93% plasma cells. The plasma cells disappeared after the 6th intrathecal injection with MTX and prednisolone and the chemotherapy was resumed. One month later, CNS relapse was apparent followed by generalized spread of the tumor mass, and she died on March 17, 2003.

The proteasome inhibitor PS-341 potentiates sensitivity of multiple myeloma cells to conventional chemotherapeutic agents: therapeutic applications.
    Blood, 2003, Mar-15, Volume: 101, Issue:6

    The proteasome inhibitor PS-341 inhibits nuclear factor-kappaB (NF-kappaB) activation, induces apoptosis in cancer cells, including multiple myeloma (MM) cells, and has marked clinical activity as a monotherapy for MM. In this study, we found that subtoxic concentrations of PS-341 potently sensitized MM cell lines and patient cells to DNA-damaging chemotherapeutic agents such as doxorubicin and melphalan, including cells resistant to these drugs and those isolated from a patient who had relapsed after PS-341 monotherapy. Moreover, PS-341 abolished cell adhesion-mediated drug resistance. Using gene expression profiling and proteomic analysis, we demonstrate that PS-341, among its other proapoptotic effects, down-regulates the expression of several effectors involved in the cellular response to genotoxic stress. These data suggest that, in addition to down-regulating the expression of apoptosis inhibitors, PS-341 inhibits genotoxic stress response pathways and thereby restores sensitivity to DNA-damaging chemotherapeutic agents. These studies, therefore, provide the framework for clinical use of this agent in combination with conventional chemotherapy.

    Gan to kagaku ryoho. Cancer & chemotherapy, 2003, Volume: 30, Issue:2

    High-dose chemotherapy with autologous peripheral blood stem cell transplantation was administered to five patients with refractory myeloma. To collect peripheral blood stem cells, apheresis was done by administering doxorubicin 40 mg/m2 on the first day, and etoposide 60 mg/m2 on the first, second, and third days, followed by G-CSF administration to harvest cells. The high-dose chemotherapy consisted of melphalan 60 mg/m2 administered for 4 days and infusion of mononuclear cells. No serious side effects were observed during the clinical course. After transplantation, complete or partial responses were achieved. APBSCT is considered to be a useful method because it had an antitumor effect against multiple myeloma that is refractory to conventional chemotherapy, as well as against multiple myeloma that is sensitive to chemotherapy, and it can be safely performed.

Autologous stem cell transplantation in multiple myeloma: improved survival in nonsecretory multiple myeloma but lack of influence of age, status at transplant, previous treatment and conditioning regimen. A single-centre experience in 127 patients.
    Bone marrow transplantation, 2003, Volume: 31, Issue:3

    High-dose therapy with autologous stem cell transplantation (ASCT) has become the treatment of choice for symptomatic eligible patients with multiple myeloma (MM). We report our centre experience and analyse retrospectively the prognostic influence of pretransplant characteristics and transplant modalities on response and survival. A total of 127 MM patients (median age: 55.2 years) were transplanted between 1994 and 2001. In all, 69 patients had IgG, 28 IgA, 23 light chain, one IgD and six non secretory MM. At the time of autograft, 6% of patients were in complete remission (CR), 73% in partial remission (PR), 12% showed minor response to previous treatment and 9% had stable or refractory disease. Prior to autograft, 79% of cases had received only one line of chemotherapy and 21% two or more lines. All patients received PBSC support after conditioning with 200 mg/m(2) melphalan alone (100 patients) or melphalan and TBI (27 patients). We evaluated the influence of age (using as cutoff value the ages of 55, 60 and 65 years), type of MM, status pre- and post-ASCT, number of lines of previous regimens, time of ASCT from diagnosis, year of autograft, dose of reinfused CD34+ cells, plasma cell infiltration and beta(2)-microglobulin at diagnosis on overall (OS) and progression-free survivals (PFS) to define patients with better prognosis. Following ASCT, 15% of patients were in CR and 81% in PR, while only two patients progressed. Median OS and PFS from transplantation were 50.4 and 23.5 months, respectively. Median OS from diagnosis was 79.7 months. Transplant-related mortality was 2.3%. Low levels of beta(2)-microglobulin and the achievement of CR post-transplant correlated with longer PFS (P<0.03 and P<0.01, respectively). The median PFS was 36.1, 23.9, 21.1 and 16.4 months for nonsecretory, IgG, IgA and light chain subtypes, respectively. Age was not an important prognostic factor at a cutoff value of 55 or 60 years. We conclude that ASCT is a safe and effective procedure even in resistant cases. The outcome was independent of age, time from diagnosis, previous treatment and conditioning regimen, but there was a tendency for better survival in the nonsecretory patients.

The proteasome inhibitor PS-341 markedly enhances sensitivity of multiple myeloma tumor cells to chemotherapeutic agents.
    Clinical cancer research : an official journal of the American Association for Cancer Research, 2003, Volume: 9, Issue:3

    Increased nuclear factor kappaB (NF-kappaB) activity is associated with increased tumor cell survival in multiple myeloma. The function of NF-kappaB is inhibited through binding to its inhibitor, IkappaB. Release of activated NF-kappaB follows proteasome-mediated degradation of IkappaB resulting from phosphorylation of the inhibitor and, finally, conjugation with ubiquitin. We report that myeloma cells have enhanced IkappaBalpha phosphorylation and increased NF-kappaB activity compared with normal hematopoietic cells. The proteasome inhibitor PS-341 blocked nuclear translocation of NF-kappaB, blocked NF-kappaB DNA binding, and demonstrated consistent antitumor activity against chemoresistant and chemosensitive myeloma cells. The sensitivity of chemoresistant myeloma cells to chemotherapeutic agents was markedly increased (100,000-1,000,000-fold) when combined with a noncytotoxic dose of PS-341 without affecting normal hematopoietic cells. Similar effects were observed using a dominant negative super-repressor for IkappaBalpha. Thus, these results suggest that inhibition of NF-kappaB with PS-341 may overcome chemoresistance and allow doses of chemotherapeutic agents to be markedly reduced with antitumor effects without significant toxicity.

Idarubicin containing regimen in multiple myeloma: preliminary results of a pilot study using a modified "TANDEM" transplant program.
    Leukemia & lymphoma, 2003, Volume: 44, Issue:2

    Tandem autologous transplant actually represents a challenge in multiple myeloma treatment, but the best conditioning regimen is still under investigation. With the aim of evaluating the feasibility of a modified tandem transplant strategy, we treated 10 multiple myeloma patients after conventional first line chemotherapy with a two step conditioning regimen consisting of high-dose melphalan (200 mg/m2) followed by high-dose melphalan (180 mg/m2) together with indarubicin (15 mg/sqm2 c.i. x 3 days) both with peripheral stem cell support. At first transplant, the median age wasyears, performance status was good and disease status was CR in 2 patients and PR in the rest. At the end of the first transplant, 70% of patients achieved CR and only mild toxicity was observed. After the second transplant further improvement of the response rate was obtained with 90% CR. However, we observed three toxic early infection-related deaths from CMV and legionella pneumonia at day + 17, +26, +54 after transplantation. Although this schedule seems to be effective in terms of response rate, the 30% TRM imposes an anthracycline dose-reduction with careful patient selection. This approach could reduce the toxic effects and maintain the efficacy of therapy at the same time.

Maintenance with pamidronate following first-line MP or VAD therapy in multiple myeloma.
    Leukemia & lymphoma, 2003, Volume: 44, Issue:2

    We investigated the anti-tumor effect of pamidronate after obtaining a decrease of serum monoclonal immunoglobulin (Ig) level by conventional chemotherapy in patients with multiple myeloma (MM) in order to evaluate whether the drug is useful as maintenance therapy for MM. Eight patients with MM received 60 mg/d pamidronate every third week for 6-18 months without chemotherapeutic agents or corticosteroids after the treatment with melphalan and prednisolone, or vincristine, adriamycin and prednisolone. Serum Ig and beta2-microglobulin (b2MG) levels were maintained at the levels obtained after the termination of chemotherapy in six and four out of eight patients, respectively. Hemoglobin levels were maintained at, or increased to more than, the levels observed at the end of chemotherapy in six patients. Decreased plasma cells in the bone marrow after the chemotherapy were evident in five patients. Two patients were categorized as non-responders, because Ig and b2MG increased and anemia progressed after treatment with the drug. Despite the very small numbers, the results suggest that pamidronate may have anti-tumor activity and be useful for treatment after the conventional chemotherapy in some cases of MM.

    Annales de medecine interne, 2003, Volume: 154, Issue:1

    Immunoglobulin D (IgD) multiple myeloma is rare, accounting for less than 2% of all patients with multiple myeloma. The main presenting features are bone pain in 70% of patients. Extramedullary involvement is less common. We report a case of Ig D lambda multiple myeloma in a 74-year-old man that was revealed by pleural effusion and dyspnea. This effusion was found to be caused by multiple myeloma after electrophoretic and cytologic assays. The patient received a course of chemotherapy with melphalan and prednisone. The patient died one month later with signs of septic shock. Pleural effusion as a first sign of Ig D multiple myeloma is rarely described and the prognosis associated with such a localisation is very poor.

Intermediate-dose cyclophosphamide and granulocyte colony-stimulating factor is a valid alternative to high-dose cyclophosphamide for mobilizing peripheral blood CD34+ cells in patients with multiple myeloma.
    Acta haematologica, 2003, Volume: 109, Issue:4

    Peripheral blood stem cells (PBSC) are widely used in the setting of dose-intensive chemotherapies in patients with multiple myeloma (MM). Although the granulocyte colony-stimulating factor (G-CSF), following chemotherapy or not, is considered the standard growth factor for mobilizing PBSC, the optimal chemotherapeutic regimen still remains to be defined. Cyclophosphamide (CTX) is an effective drug in the treatment of MM which is capable of mobilizing PBSC if followed by growth factors, even though administration of high-dose CTX (7 g/m(2)) results in severe toxicity requiring hospitalization and increasing costs. We have retrospectively analyzed the results obtained in 38 newly diagnosed MM patients treated with 1.2 g/m(2) CTX on days 1 and 3 combined with 40 mg dexamethasone daily for 4 days. The results were compared with those obtained in 25 newly diagnosed MM patients treated with 7 g/m(2) CTX. A higher number of CD34+ cells/kg was collected during the first leukapheresis and a statistically significant lower consumption of G-CSF was observed following two doses of 1.2 g/m(2) CTX compared to the 7 g/m(2) CTX dose. The possibility of treating patients with day-hospital regimens, with a satisfactory yield of hematopoietic cells harvested, may have relevant economic implications for treatment strategies in MM patients.

    Cytogenetic abnormalities (CA), especially of chromosome 13, have been used to identify a subgroup of previously untreated multiple myeloma (MM) patients with very poor prognosis despite high-dose therapy (HDT). We examined the prognostic implications of CA in 1000 MM patients receiving melphalan-based tandem autotransplants (median follow-up, 5 years). Negative consequences for both overall survival (OS) and event-free survival (EFS) in the presence of any CA were confirmed, especially when detected within 3 months of HDT. In the context of standard prognostic factors (SPF), 'MM-MDS' (MM karyotype that contains, in addition, CA typical of MDS) imparted a poor OS and EFS, after adjusting for any CA and all individual CA. One-year mortality was also high, especially for the MM-MDS subgroup with trisomy 8 within a MM signature karyotype (87%vs 34% in its absence, P < 0.001). No patient remained event free 5 years post transplant in the presence of these baseline high-risk CA. However, certain trisomies (e.g. chromosomes 7 and 9) and del 20 had favourable clinical consequences. The higher risk that is associated with CA compared with SPF justifies routine cytogenetic studies in all patients with MM at diagnosis and whenever additional treatment decisions are considered, such as in planning HDT either for initial response consolidation, at the time of primary unresponsiveness to induction therapy, or at relapse.

Early recurrence of rheumatoid arthritis after nonmyeloablative allogeneic blood stem cell transplantation in a patient with multiple myeloma.
    Bone marrow transplantation, 2003, Volume: 32, Issue:6

    Allogeneic blood stem cell transplantation with reduced conditioning has been proposed as a new, potentially curative treatment option for patients with rheumatoid arthritis (RA). We report a 60-year-old woman with RA and coexisting multiple myeloma who was treated with high-dose melphalan and autologous blood stem cell transplantation (BSCT) followed by a nonmyeloablative allogeneic BSCT from her healthy dizygotic twin brother. She achieved a complete remission of her RA after autologous BSCT, but relapsed early despite complete donor chimerism following successful allogeneic transplantation with reduced intensity conditioning. This case illustrates that allogeneic BSCT following nonmyeloablative conditioning may be an uncertain option for curing patients with RA.

Treosulfan is an effective inducer of cell death in myeloma cell lines and primary myeloma cells from patients.
    British journal of haematology, 2003, Volume: 122, Issue:6

    Multiple myeloma is a non-curable haematological disease involving transformed plasma cells. High rates of complete remission can be achieved with autologous peripheral blood stem cell transplantation. Treosulfan is an alkylating substance that has been used in the treatment of ovarian carcinomas for many years. It has a favourable side-effect profile even at high-dose protocols. Thus, the objective of this study was to evaluate the effect of treosulfan on myeloma cells. The treatment of the myeloma cell lines, NCI-H929 and U266, with treosulfan led to apoptosis in both cell lines in a dose- and time-dependent manner. The induction of apoptosis was accompanied by cleavage of caspases -3 and -9 as well as downregulation of the antiapoptotic protein Mcl-1 and upregulation of the inhibitor of cyclin-dependent kinases, p21WAF1/CIP1. Furthermore, 100 micro mol/l treosulfan was capable of inducing cell death in 63.6 +/- 23.9% of primary myeloma cells, whereas treatment with the same concentration of melphalan showed 59.7 +/- 26% cell death. These in vitro concentrations were at least 10-fold lower than achievable plasma levels, even at conventional doses of treosulfan. Our results suggest that treosulfan might be an appropriate candidate for novel treatment protocols for patients with multiple myeloma.

Unusual IgM-secreting multiple myeloma in a dog.
    Journal of the American Veterinary Medical Association, 2003, Sep-01, Volume: 223, Issue:5

    A 4-year-old castrated male dog was evaluated because of multiple-limb lameness. Signs of pain were elicited during palpation of the regions of the proximal tibial metaphyses and distal left radial diaphysis. Radiography revealed osteolytic lesions of the long bones. Blood analyses revealed hypercalcemia and transient cytopenias. Serum protein electrophoresis did not reveal a monoclonal gammopathy; however, urine protein electrophoresis revealed Bence Jones proteinuria. Serial diagnostic sampling of bone lesions, immunohistochemical staining methods, and serum and urine protein immunoelectrophoresis were required to establish a diagnosis of multiple myeloma. Two IgM components were identified via serum protein immunoelectrofixation. The dog improved clinically after initiation of chemotherapy with melphalan and prednisone; however, the dog ultimately was euthanatized because of pathologic fracture. The case was unique because there was lack of vertebral involvement, an unusual gammopathy, and difficulty in identifying myeloma cells via serial sampling.

[Diagnosis of multiple myeloma by demonstrating plasma cells in bronchoalveolar lavage].
    Deutsche medizinische Wochenschrift (1946), 2003, Sep-19, Volume: 128, Issue:38

    A 61-year-old man was transferred from a peripheral hospital with the diagnosis of interstitial lung disease and an unclear mediastinal tumour. At the time of admission the patient had congestive heart disease NYHA class IV.. The echocardiogram showed a small left ventricle with concentric hypertrophy and a left ventricular ejection fraction of 35 %. The myocardium was relatively echo-rich with solid structures inside. Chest X-ray showed a massive rightsided pleural effusion. The abdominal ultrasound demonstrated ascites and hepatomegaly. The bronchoalveolar lavage showed an increased part of CD3 negative and CD16/CD56 positive cells, which were identified as plasma cells by light and electron microscopy. Aspiration and investigation of the bone marrow verified the diagnosis of a IgG multiple myeloma, highly differentiated characterised by monoclonal expression of light-lambda chains. Additionally Bence-Jones-proteins were found in the urine and osteolysis in the x-ray of the skull and the humerus.. Multiple myeloma, IgG-lambda, stage IIA.. Chemotherapy with prednisolone and melphalan was initiated. His general condition increased after administration of the first cycle of chemotherapy.. Cardiopulmonary involvement is seldom seen in multiple myeloma but should be excluded when clinical symptoms are present.

Gene-specific formation and repair of DNA monoadducts and interstrand cross-links after therapeutic exposure to nitrogen mustards.
    Clinical cancer research : an official journal of the American Association for Cancer Research, 2003, Oct-01, Volume: 9, Issue:12

    To investigate the possibility of measuring the gene-specific DNA damage after therapeutic exposure to nitrogen mustards and to examine its relationship with the clinical response.. The kinetics of gene-specific monoadducts and interstrand cross-link formation/repair were measured in the p53 and N-ras genes. DNA extracted from human peripheral lymphocytes following in vitro exposure to melphalan or therapeutic exposure to melphalan or cyclophosphamide was used.. When lymphocytes were treated in vitro with biologically relevant doses of melphalan, monoadducts accumulated rapidly in both p53 and N-ras genes, reaching maximal levels within 2 h, whereas the highest interstrand cross-link levels were found within 8 h. Thereafter, the adducts were repaired with half-lives of 14.5 +/- 0.3 h (p53) or 18.8 +/- 1.5 h (N-ras) for monoadducts and 12.4 +/- 0.8 h (p53) or 14.1 +/- 2.2 h (N-ras) for interstrand cross-links. Moreover, peak levels of monoadducts in both genes were observed 2 h after treatment in peripheral leukocytes from patients with multiple myeloma treated with high-dose i.v. melphalan, supported by autologous stem cell transplantation, whereas interstrand cross-links were maximal within 8 h. Of seven patients examined, the three who showed the least levels of DNA damage did not respond to the high-dose melphalan.. This is the first report showing that it is feasible to measure gene-specific DNA damage in a readily accessible tissue of humans exposed to bifunctional alkylating drugs and to examine, at the level of the individual patient, the relationships between the induction/repair of cytotoxic DNA damage and clinical response or long-term complications.

Genotypic and phenotypic comparisons of de novo and acquired melphalan resistance in an isogenic multiple myeloma cell line model.
    Cancer research, 2003, Nov-15, Volume: 63, Issue:22

    Cancer cell adhesion confers a transient, de novo drug-resistant phenotype referred to as cell adhesion-mediated drug resistance (CAM-DR). In this report, we extend the CAM-DR phenotype to primary specimens from patients with myeloma, providing further evidence that CAM-DR is a viable clinical form of drug resistance. To examine mechanisms of cellular resistance to melphalan, we compared genotypic and phenotypic profiles of acquired and de novo melphalan resistance in an isogenic human myeloma cell line. Acquired melphalan resistance (8226/LR5) was associated with decreased drug-induced DNA damage and a complex gene expression profile showing that genes involved in the Fanconi anemia DNA repair pathway are increased in the LR5 cells compared with drug-sensitive or adherent cells. In contrast, cells adhered to fibronectin accumulate similar amounts of DNA damage compared with drug-sensitive cells but are protected from melphalan-induced mitochondrial perturbations and caspase activation. Levels of the proapoptotic protein Bim were significantly reduced in adherent cells. Gene expression changes associated with de novo resistance were significantly less complex compared with acquired resistance, but a significant overlap in gene expression was noted involving cholesterol synthesis. We propose that myeloma cell adhesion promotes a form of de novo drug resistance by protecting cells from melphalan-induced cytotoxic damage and that this transient protection allows cells to acquire a more permanent and complex drug resistance phenotype associated with a reduction in drug induced DNA damage.

Potential usefulness of serum p53 for laboratory management of plasma cell dyscrasias.
    Journal of experimental & clinical cancer research : CR, 2003, Volume: 22, Issue:4

    We measured the serum levels of p53 mutant protein (p53M-ELISA) in 65 patients with plasma cell dyscrasia (PCD) and compared them with some conventional laboratory variables. Our aim was to assess, for the first time, the potential of this parameter as a new marker for laboratory management of PCD. Twenthy-tree out of 65 patients had monoclonal gammapathy of undetermined significance (MGUS) and 42 suffered from multiple myeloma (MM). MM patients, with no prior chemotherapy consecutively entered this study. They were treated with standard regimens of Melphalan and Prednisone (MP) and were analyzed for serum p53M level from the time of diagnosis to response to therapy or death. A subgroup of nine patients was regularly monitored for changes occurring in p53M levels during MP therapy. Serum levels of p53M were elevated in MM patients compared with MGUS and healthy controls (p = 0.002). Significantly higher p53M levels were shown by MM patients refractory to chemotherapy than by responding patients (0.38 ng/ml vs 0.22 ng/ml, p = 0.05). The measurement of serum p53M in the nine patients during the course of chemotherapy correlated with disease progression or response to therapy. If confirmed on a larger series of patients, these results suggest a potential role of serum p53 mutant levels in laboratory management of PCD patients.

beta-lapachone, a novel plant product, overcomes drug resistance in human multiple myeloma cells.
    Experimental hematology, 2002, Volume: 30, Issue:7

    To evaluate the anti-tumor potential of beta-lapachone in multiple myeloma (MM) cell lines (U266, RPMI8226, and MM.1S); MM cell lines resistant to dexamethasone (MM.1R), melphalan (RPMI8226/LR5), doxorubicin (RPMI8226/DOX40), and mitoxantrone (RPMI8226/ MR20); and MM cells from patients (MM1-MM4).. Cytotoxicity of beta-lapachone was assessed by MTT and [3H]-thymidine uptake assays. Apoptosis was analyzed using propidium iodide staining, DNA fragmentation, TUNEL assay, caspase-9 colorimetric assay, and immunoblotting for caspase-3, poly (ADP-ribose) polymerase (PARP), and caspase-8 cleavage products. Paracrine growth of MM cells was assessed by [3H]-thymidine uptake in cultures of bone marrow stromal cells (BMSCs) and MM cells. Interleukin-6 (IL-6) and vascular endothelial growth factor (VEGF) secretion in the culture supernatants was measured by specific enzyme-linked immunosorbent assays (ELISAs).. beta-lapachone showed significant cytotoxicity in MM cells (IC(50): 4-8 microM). In contrast, normal peripheral blood mononuclear cells (PBMCs) and BMSCs from MM patients were relatively resistant (IC(50): 8-16 microM). IL-6 did not protect against beta-lapachone-induced apoptosis in MM.1S cells, and dexamethasone showed additive cytotoxicity. beta-lapachone also decreased binding of MM.1S cells to BMSCs; abrogated IL-6 and VEGF secretion triggered by adhesion of BMSCs to MM.1S cells; reduced proliferation of MM.1S cells adherent to BMSCs; and decreased intracellular adhesion molecule-1 (ICAM-1) expression on MM.1S cells. Furthermore, beta-lapachone induced typical PARP cleavage, increased caspase-9 proteolytic activity, and activation of caspase-3, without activation of caspase-8 in U266 cells.. These studies provide a framework for clinical evaluation of beta-lapachone to improve the outcome for patients with MM.

Oral melphalan at diagnosis hampers adequate collection of peripheral blood progenitor cells in multiple myeloma.
    Haematologica, 2002, Volume: 87, Issue:8

    Since optimal collection of peripheral blood progenitor cells (PBPC) remains crucial for high-dose therapy in patients with multiple myeloma (MM) in relapse phase or refractory to chemotherapy, we evaluated several variables that may influence mobilization.. Eighty-nine patients who underwent a standard mobilization procedure with cyclophosphamide (3 g/m2) and growth factors entered the study. A composite collection totalling at least 2x106 CD34+/kg was defined as a sufficient yield: 59 patients achieved an adequate collection. A reliable factor to predict adequate yields was prior therapy: an adequate collection was obtained in 92% of patients treated with conventional non-alkylating therapy (VAD-based regimens), in 56% treated with oral melphalan and in 23% who had received intravenous melphalan.. The three groups were similar for most clinical features. After adjustment for several potential confounders, the probability of an adequate PBPC collection remained higher in the group treated with non-alkylating agents, with an odds ratio (OR) of 6.14 (95% confidence interval, CI=1.34, 28.13) and lower in those treated with intravenous melphalan (OR=0.08; CI=0.01-0.61), when compared to the group treated with oral melphalan. Among the other prognostic factors (stage, percentage of bone marrow plasma cells, b2-microglobulin, labeling index, isotype, monoclonal component, Bence-Jones proteinuria) evaluated at diagnosis, there was no clear association with progenitor cell yield.. In conclusion, patients who are potential candidates for high-dose therapy with PBPC support should not receive conventional alkylating therapy, even orally. Alternatively, progenitor cells should be collected early in the course of MM.

Long-term results (12 years) of high-dose therapy in 127 patients with de novo multiple myeloma.
    Leukemia, 2002, Volume: 16, Issue:9

    This report describes the long-term outcome of a cohort of 127 de novo multiple myeloma patients treated with at least one course of high-dose therapy (HDT) in a single institution between June 1985 and December 1995, for whom the minimum follow-up duration for survivors is 6 years. The 12-year overall survival (OS) and event-free survival (EFS) rates are 24.9% and 3.1%, respectively, and the median survival and EFS are 49 and 17 months, respectively. Only four patients are alive and disease-free 79, 90, 132 and 153 after the first HDT, respectively. Three of them received a subsequent allogeneic bone marrow transplantation. Three factors significantly influence OS in this series: B2M at diagnosis, age, and the completion of a second HDT. The 10-year survival is 18.9% for the group of patients with B2M level >3 mg/l at diagnosis as compared with 41% for patients with B2M < or =3, with a median survival of 31 months vs 73 (P = 0.01). The 10-year survival is 23.4% for the group of patients aged >55 years as compared with 36.5% for patients aged <55 years, with a median survival of 34.5 months vs 70.5 (P = 0.04). The 10-year survival is 20.4% for the group of patients who did not receive a second HDT as compared with 35.2% for patients who completed a second HDT, with a median survival of 29 months vs 70 (P = 0.02). In this study we show that some patients treated with HDT experience durable remission and prolonged survival. This survival is significantly influenced by age (< or =55 years), B2M at diagnosis (< or =3 mg/l) and by the completion of two cycles of HDT.

Recovery of renal function after autologous stem cell transplantation in myeloma patients with end-stage renal failure.
    Bone marrow transplantation, 2002, Volume: 30, Issue:7

    The disease-free survival of patients with myeloma and severe renal failure after high-dose melphalan and autologous stem cell rescue is similar to those with normal renal function at the time of the autograft. However, recovery of renal function after intensive treatment is uncommon and patients with end-stage renal failure continue to be dialysis-dependent. We report two patients with myeloma who required regular haemodialysis from diagnosis, but became dialysis-independent after a high-dose melphalan autograft. Thus, in some patients, renal function may be partially salvageable despite the requirement for dialysis at the time of autografting.

Flow cytometric disease monitoring in multiple myeloma: the relationship between normal and neoplastic plasma cells predicts outcome after transplantation.
    Blood, 2002, Nov-01, Volume: 100, Issue:9

    Conventional monitoring strategies for myeloma are not sufficiently sensitive to identify patients likely to benefit from further therapy immediately after transplantation. We have used a sensitive flow cytometry assay that quantitates normal and neoplastic plasma cells to monitor the bone marrow of 45 patients undergoing high-dose chemotherapy. Neoplastic plasma cells were detectable at 3 months after transplantation in 42% of patients. Once detected, neoplastic cell levels increased steadily until clinical progression: these patients had a significantly shorter progression-free survival (PFS) (median, 20 months) than those with no detectable disease (median, longer than 35 months; P =.003). Neoplastic plasma cells were detectable in 27% (9 of 33) of immunofixation-negative complete-remission patients. These patients had a significantly shorter PFS than immunofixation-negative patients with no detectable neoplastic plasma cells (P =.04). Normal plasma cells were present in 89% of patients immediately after transplantation, but were not sustained in most cases. Patients with only normal phenotype plasma cells present at 3 months after transplantation and also at second assessment had a low risk of disease progression. Patients with neoplastic plasma cells present at 3 months after transplantation, or with only normal plasma cells present at first assessment and only neoplastic plasma cells at second assessment, had a significantly higher risk of early disease progression (P <.0001) with a 5-year survival of 54% for the high-risk group, compared with 100% in the low-risk group (P =.036). Analysis of normal and neoplastic plasma cell levels is more sensitive than immunofixation and can identify which patients may benefit from additional treatment strategies at an early stage after transplantation.

Combined treatment with the checkpoint abrogator UCN-01 and MEK1/2 inhibitors potently induces apoptosis in drug-sensitive and -resistant myeloma cells through an IL-6-independent mechanism.
    Blood, 2002, Nov-01, Volume: 100, Issue:9

    The effects of combined exposure to the checkpoint abrogator UCN-01 and pharmacologic MEK1/2 inhibitors were examined in human multiple myeloma (MM) cell lines. Treatment of RPMI8226, NCI-H929, and U266 MM cells with a minimally toxic concentration of UCN-01 (150 nM) for 24 hours resulted in mitogen-activated protein (MAP) kinase activation, an effect that was blocked by coadministration of the MEK1/2 inhibitor PD184352. These events were accompanied by enhanced activation of p34(cdc2) and a marked increase in mitochondrial damage (loss of DeltaPsim; cytochrome c and Smac/DIABLO (direct IAP binding protein with low pI) release), poly(ADP-ribose) polymerase (PARP) cleavage, and apoptosis. PD184352/UCN-01 also dramatically reduced clonogenic survival in each of the MM cell lines. In contrast to As(2)0(3), apoptosis induced by PD184352/UCN-01 was not blocked by the free-radical scavenger N-acetyl-L-cysteine. Whereas exogenous interleukin 6 substantially prevented dexamethasone-induced lethality in MM cells, it was unable to protect them from PD184352/UCN-01-induced apoptosis despite enhancing Akt activation. Insulinlike growth factor 1 (IGF-1) also failed to diminish apoptosis induced by this drug regimen. MM cell lines selected for a high degree of resistance to doxorubicin, melphalan, or dexamethasone, or displaying resistance secondary to fibronectin-mediated adherence, remained fully sensitive to PD184352/UCN-01-induced cell death. Finally, primary CD138(+) MM cells were also susceptible to UCN-01/MEK inhibitor-mediated apoptosis. Together, these findings suggest that simultaneous disruption of cell cycle and MEK/MAP kinase signaling pathways provides a potent stimulus for mitochondrial damage and apoptosis in MM cells, and also indicate that this strategy bypasses the block to cell death conferred by several other well-described resistance mechanisms.

Pancytopenia responding to treatment of hyperthyroidism: a clinical case and review of the literature.
    Clinical and laboratory haematology, 2002, Volume: 24, Issue:6

    A 46-year-old-man received high dose chemotherapy and an autologous stem-cell transplant for multiple plasmacytoma. He had a prolonged period of pancytopenia post-transplantation, which was thought to be due to a suboptimal dose of transplanted stem cells in combination with the effects of interferon therapy and an altered bone marrow microenvironment. Twenty-eight months after the transplant he was found to be hyperthyroid. Anti-thyroid therapy has led to a sustained improvement in his pancytopenia.

Continuous low dose of melphalan and prednisone in patients with multiple myeloma of very old age or severe associated disease.
    Drugs & aging, 2002, Volume: 19, Issue:12

    The management of elderly patients with multiple myeloma is a relevant problem because it concerns a great number of patients. Patients with multiple myeloma who are very old or who have severe associated diseases have a dismal outcome. For these patients we retrospectively evaluated the effect of a mild approach with continuous low-dose melphalan and prednisone (cMP).. 109 patients with multiple myeloma, observed between 1985 and 2000, were treated with cMP; 67 were treated at time of diagnosis (group A; median age 78 years) and 42 as a second or subsequent line of therapy (group B; median age 72 years). The toxicity of the treatment was compared with a control group of 29 patients aged over 70 years, treated in the same institution with the conventional cyclical melphalan/prednisone regimen.. Major or minor responses were obtained in 32% of patients in group A and 13% of patients in group B. Disease was stabilised in 45% of group A and 47% of group B and progressed in 5 and 18%, respectively. Median survival was, respectively, 19 and 24 months in group A and B. Among the 42 patients who received cMP as a second-line therapy (group B), 36 (86%) had previously been treated according to the standard cyclical melphalan/prednisone schedule; of these 12 (33%) obtained a better M protein reduction after cMP compared with the previous response to first-line cyclical melphalan/prednisone. The cMP schedule was generally well tolerated, and the rate of haematological toxicity was lower than for a historical control group receiving cyclical melphalan/prednisone.. The cMP treatment schedule is well tolerated and results in a high proportion of patients with stable disease, with acceptable survival even in patients with advanced disease.

[DAD, new intensive chemotherapy for patients with myeloma: a preliminary report].
    [Rinsho ketsueki] The Japanese journal of clinical hematology, 2002, Volume: 43, Issue:11

    A new intensive chemotherapy regimen, DAD, composed of doxorubicin, melphalan and dexamethasone, was given to 17 patients with multiple myeloma. The end point of this regimen was to obtain a deep posttreatment nadir in the M-protein levels so as to increase the chance of plateau attainment which would be associated with prolonged survival in each patient. It was noteworthy that all the 17 evaluable patients achieved a partial response. Nine of the 17 (52.9%) attained a plateau. Ten of the 17 patients (58.8%) obtained a deep posttreatment nadir in their M-protein levels (IgG < 2,000 mg/dl, IgA < 1,000 mg/dl, BJP = 0 g/dl/day), and six of them reached a plateau phase, which was not significantly more frequent than those who did not obtain a deep posttreatment nadir in their M-protein levels (three of seven reached plateau phase). The median survival of the 17 patients (37.6 months) was significantly prolonged compared with that of patients treated with our previous chemotherapy regimens, VMCP (22.5 months) and MMPP (23.5 months), and was comparable to that of MMCP (29.5 months).

Use of melphalan, thalidomide, and dexamethasone in treatment of refractory and relapsed multiple myeloma.
    Medical oncology (Northwood, London, England), 2002, Volume: 19, Issue:4

    Twenty-one patients with relapsed and refractory Durie-Salmon stage III multiple myeloma who had either failed at least three previous regimens or presented with poor performance status, neutropenia, or thrombocytopenia were treated with up to four cycles of combination melphalan (50 mg intravenously), thalidomide (titrated to target of 400 mg orally daily), and dexamethasone (40 mg/day orally on d 1 to 4) every 4-6 wk. Maintenance treatment consisting of daily thalidomide and monthly dexamethasone was continued until disease progression. Although generally tolerated, combination melphalan/thalidomide/dexamethasone produced grade 4 neutropenia and thrombocytopenia in 52% and 38% of patients, respectively. Grade 3 nonhematologic toxicities included fatigue (14% of patients), neuropathy/paresthesia (5%), and nausea (5%). Four patients died while on therapy: two from neutropenic complications and two from progressive disease. Melphalan/ thalidomide/dexamethasone was highly active in this poor prognosis population: Serum monoclonal protein reductions > or = 25% occurred in 14 (70%) of 20 evaluable patients, including 1 patient with a complete response and 2 (13%) patients with reductions of 96%. Median progression-free-survival was 270 d (range: 73 to > 787 d) and median overall survival was 382 d. Median progression-free survival (> 420 d) has not been reached among patients responding to melphalan/thalidomide/dexamethasone. These results show that melphalan/thalidomide/dexamethasone therapy is active and generally tolerated in heavily pretreated multiple myeloma patients whose prognosis is otherwise poor.

High dose chemotherapy and allogenic peripheral blood stem cell transplantation for multiple myeloma evolving from intra-abdominal plasmacytoma.
    Zhonghua yi xue za zhi = Chinese medical journal; Free China ed, 2002, Volume: 65, Issue:11

    Solitary plasmacytomas include extramedullary plasmacytomas and those found in the bone. Seventy percent of patients are male and the median age is 50-55 years, younger than that for plasma cell myeloma. Most solitary plasmacytomas of bone eventually evolve to plasma cell myeloma within 2-10 years, while the extramedullary ones do so infrequently. We present an unusual case of intra-abdominal plasmacytoma in a young woman which was misdiagnosed and treated as T cell lymphoma initially. Typical manifestations of plasma cell myeloma appeared one year later. High dose chemotherapy followed by allogeneic peripheral stem cell blood transplantation (allo-PBSCT) was given. Relapse in skin occurred one year after allo-PBSCT, and was treated with wide excision and local irradiation. The patient was well and alive without evidence of disease 4 years after wide excision of the recurrence of chest wall solitary plasmacytoma and local radiotherapy.

Reversible restrictive cardiomyopathy due to light-chain deposition disease.
    Mayo Clinic proceedings, 2002, Volume: 77, Issue:2

    Systemic light-chain deposition due to plasma cell dyscrasias manifests as a form of restrictive cardiomyopathy with diastolic ventricular dysfunction. Although these manifestations are likely to be cardiac amyloidosis, whether these pathological conditions are reversible after treatment of the underlying plasma cell disorders is unknown. To our knowledge, we describe the first patient with cardiac light-chain deposition due to multiple myeloma in whom echocardiographic and biochemical factors of cardiac function were ameliorated dramatically after remission of this disorder. We emphasize that restrictive cardiomyopathy due to light-chain deposition may be reversible and have a relatively better prognosis after remission of plasma cell dyscrasias.

Predicting long-term (> or = 5 years) event-free survival in multiple myeloma patients following planned tandem autotransplants.
    British journal of haematology, 2002, Volume: 116, Issue:1

    Although outcome in multiple myeloma (MM) patients has improved significantly with the introduction of autotransplants (AT), the curability of this approach remained to be demonstrated. Therefore, we analysed outcome and prognostic factors using a logistic regression model in 515 consecutive newly diagnosed and previously treated patients intended to receive melphalan-based tandem transplants with follow up of > or = 5 years. One quarter of patients had event-free survivals (EFS) > or = 5 years with no further relapses seen after 7 years (46 patients on plateau). On multivariate analysis, factors associated with EFS > or = 5 years were absence of chromosome 11 and 13 abnormalities (odds ratio: 6.1), < or = 12 months of preceding standard-dose therapy (SDT) (OR: 2.6) and beta-2 microglobulin (B2M) level < or = 2.5 mg/l at time of first AT (OR: 1.7). Patients with only favourable variables (25%) had a 7-year EFS in excess of 35%, compared with 15% and 10%, respectively, with one (43%) or two unfavourable variables (27%), and 0% for 5% of patients with three unfavourable variables (P < 0.0001). Using a 1-year landmark analysis to allow for guaranteed time and thereby excluding early treatment failures, attaining a complete remission (CR) had no significant effect on long-term survival. Our data are consistent with cure in MM patients with a CR duration . or = 7 years and re-establishment of a monoclonal gammopathy of undetermined significance (MGUS) phase in those with persistent evidence of disease post transplantation, but without disease progression > or = 7 years.

Myeloablative treatments for multiple myeloma: update of a comparative study of different regimens used in patients from the Spanish registry for transplantation in multiple myeloma.
    Leukemia & lymphoma, 2002, Volume: 43, Issue:1

    After a previous analysis that did not detect clear differences in the results of three conditioning regimens used for autologous stem cell transplantation (ASCT) in patients from the Spanish Registry for Transplant in Multiple Myeloma (MM), we have updated the registry, including a larger number of cases and a fourth conditioning regimen with a longer follow-up. We evaluate 472 MM patients treated with 200 mg/m2 melphalan (MEL200), 135 patients treated with 140 mg/m2 melphalan plus total body irradiation [(MEL140 + TBI)], 186 patients treated with 12 mg/kg busulphan plus 140 mg/m2 melphalan (BUMEL) and 28 patients treated with 14 mg/kg busulphan followed by cyclophosphamide 120 mg/kg (BUCY). There were no significant differences in respect to either transplant related death or haematological recovery, regardless of growth factor use, between the four conditioning programs. Nevertheless, hospitalization time with MEL200 was less than with BUMEL when growth factors were used (19+/-9 vs. 25+/-9 days, P = 0.009) and less than with MEL140 + TBI without growth factors (20+/-8 days vs. 27+/-9 days, P = 0.002). In patients with measurable disease at ASCT (non-complete remission [CR]), BUMEL achieved a 51% CR vs. 43%-31% in the other groups (P = 0.007). The response rate for patients in partial remission (PR) at ASCT was 100% with BUMEL vs. 93%-86% in the other groups (P between 0.02 and 0.0007). The median overall survival (OS) for the BUMEL group was 57 months (95% confidence interval [CI]: 51-78) as compared to 45 (CI: 36-64) months for the MEL200 group and 39 (CI: 28-72) months for the MEL140 + TBI and BUCY groups. The median event free survival (EFS) was longer in the BUMEL group [30 (CI: 22-44) mo] than in the MEL200 [22 (CI: 18-26) mo], BUCY [23 (CI: 11-50) mo] or MEL140 + TBI groups [20 (CI: 15-29) mo]. Nevertheless, the differences in OS and EFS did not reach statistical significance in either the univariate analysis or the multivariate analysis adjusted with other high prognostic weight factors. As in the initial study, differences in regards to the anti-myeloma effect of the conditioning regimens are not conclusive. However, the better response rates associated with the favorable tendency in outcome achieved with BUMEL, continue to justify further prospective studies.

Thalidomide as salvage therapy for VAD-refractory multiple myeloma prior to autologous PBSCT.
    Bone marrow transplantation, 2002, Volume: 29, Issue:7

    Several trials have shown the activity of thalidomide (THAL) in relapsed multiple myeloma (MM) patients failing PBSCT or conventional chemotherapy. PBSCT is considered standard treatment for most patients requiring therapy for MM; however, patients with VAD-resistant disease may not be able to receive PBSCT due to rapidly advancing disease. We report four cases of VAD-refractory MM salvaged with THAL + VAD followed by PBSCT. All patients underwent stem cell mobilization with cyclophosphamide (Cy) (4.5 g/m(2)) and GMCSF. Melphalan (140-200 mg/m(2)) was given as conditioning. All patients engrafted within 12-16 days after PBSCT. Day +100 evaluation showed the following: very good partial response (n = 1) and complete response (n = 3). After a median follow-up to 153 days, two patients continue to take THAL with no signs of disease progression. One patient developed CHF and was taken off THAL while another patient has died of progressive disease while on THAL (MTD 50 mg). In conclusion, VAD-refractory patients were salvaged with the addition of THAL to VAD. They were subsequently able to undergo autologous PBSCT for MM, which will likely improve their overall survival. This suggests that THAL and other related immunomodulatory drugs may prove useful for initial MM therapy in combination with standard chemotherapy followed by PBSCT.

Superior efficacy of MMCP regimen compared with VMCP and MMPP regimens in the treatment of multiple myeloma.
    Internal medicine (Tokyo, Japan), 2002, Volume: 41, Issue:4

    A newly designed combination chemotherapy for multiple myeloma, MMCP [ranimustine (MCNU), melphalan (MPH), cyclophosphamide (CPM) and prednisolone (PSL)], was analyzed and compared with the results of our previous randomized trial of VMCP [vincristine, MPH, CPM and PSL] and MMPP [MCNU, MPH, procarbazine and PSL].. MCNU (33.3 mg/m2, div) on day 1 and MPH (4 mg/m2, po), CPM (66.7 mg/m2, po) and PSL (30 mg/m2, po) from day 1 to 4, were administered. Each cycle was repeated every 3 weeks.. From January 1991 until August 1995, 104 patients with multiple myeloma diagnosed at 10 hospitals of Nagoya Cooperative Study Group were enrolled.. Of the 87 evaluable patients, partial response rate for MMCP was 65.5% and was significantly higher than that of VMCP (13/47=27.7%, p<0.0001) and that of MMPP (21/47=44.7%, p=0.0196). A plateau attainment was observed in 49.4%. The percentage of the patients who attained plateau was significantly increased in the MMCP arm than in the VMCP arm (19.1 %, p=0.0017) but was not in comparison with that of MMPP arm (42.6%, p=0.6790). Patients treated with MMCP survived significantly longer than those treated with VMCP or MMPP (p=0.0009 by generalized Wilcoxon test, p=0.0023 by log-rank test) with median survival for MMCP being 31.6 months, for VMCP 22.5 months, and for MMPP 22.9 months. No significant differences were observed with respect to adverse effects among the three regimens.. The newly designed MMCP is a candidate as an induction chemotherapy for multiple myeloma.

Repair of DNA interstrand crosslinks as a mechanism of clinical resistance to melphalan in multiple myeloma.
    Blood, 2002, Jul-01, Volume: 100, Issue:1

    Melphalan is widely used as a preparative agent in patients with multiple myeloma (MM) undergoing autologous stem cell transplantation (SCT). Although disease relapse is the major cause of death after a melphalan-conditioned autograft, the mechanism remains unclear. Melphalan produces a number of DNA adducts with the DNA interstrand crosslink (ICL) considered to be the critical cytotoxic lesion. By using a modification of the single-cell gel electrophoresis (Comet) assay, we have measured formation and repair of DNA ICL in plasma cells from melphalan- naive and melphalan-treated patients (ie, those who have relapsed after a melphalan-conditioned autologous SCT or oral melphalan therapy). Similar levels of dose-dependent DNA interstand crosslinking were observed in cells from both melphalan-naive and -treated patients. However, marked differences in ICL repair were observed: cells from naive patients showed no repair, whereas those from treated patients exhibited between 42% and 100% repair at 40 hours. In vitro sensitivity to melphalan in plasma cells was found to correlate with ICL repair. These findings suggest that ICL repair may be an important mechanism by which melphalan resistance emerges after autologous SCT or oral therapy. This mechanism may have implications for MM patients undergoing melphalan therapy.

The bone marrow stromal microenvironment influences myeloma therapeutic response in vitro.
    Leukemia, 2001, Volume: 15, Issue:2

    The bone marrow microenvironment supports growth and differentiation of normal hematopoietic cells and can contribute to malignant growth. Since myeloma cells localize and accumulate in bone marrow, it is important to understand the influence of the bone marrow microenvironment not only on the growth of the malignant cells, but also on the therapeutic response of myeloma cells. Growth factors such as interleukin-6 (IL-6) produced by bone marrow stromal cells can protect myeloma cells from glucocorticoid-induced apoptosis. We examined the effect of myeloma cells-bone marrow stromal cells interaction in vitro on several therapeutic treatments. An interleukin-6-dependent myeloma cell line ANBL6 was used and treated with dexamethasone, doxorubicin, and melphalan in the presence of bone marrow stromal cells. Stromal cells were able to protect ANBL6 from dexamethasone, but significantly enhanced the effect of doxorubicin and melphalan. IL-6-induced bcl-XL and cyclin D2 expression in ANBL6 cells, but dexamethasone was able to suppress both bcl-XL and cyclin D2 expression in ANBL6. Doxorubicin and melphalan were able to suppress bcl-XL expression only in the presence of IL-6. We also looked at the effect of activating mutations of N-ras in myeloma cells interacting with stromal cells on therapeutic responses. Surprisingly, ANBL6 N-ras shows significant resistance to all drugs used. Notably, the presence of stromal cells did not alter ANBL6 Nras cells' drug resistance. These results suggest both the bone marrow microenvironment and genetic alterations of myeloma cells can independently impact on therapeutic responses.

The impact of attaining a minimal disease state after high-dose melphalan and autologous transplantation for multiple myeloma.
    British journal of haematology, 2001, Volume: 112, Issue:3

    Initial studies with high-dose therapy (HDT) in myeloma suggest some beneficial effects of attaining a complete response (CR); however, the effect on survival is difficult to assess owing to inconsistencies in the definition of response between studies. We have analysed 96 newly diagnosed patients aged less than 65 years who received HDT and assessed the effect of response on survival using electrophoresis, immunofixation and fluorescent IgH polymerase chain reaction (PCR) to define CR. Patients received induction chemotherapy with C-VAMP (adriamycin, vincristine, methylprednisolone, cyclophosphamide) followed by melphalan 200 mg/m2 and reinfusion of peripheral blood stem cells. There was a high response to C-VAMP [CR = 24%, partial response (PR) = 64%], with all but one patient improving the depth of response after HDT (CR = 69%, PR = 31%). The progression-free survival (PFS) and overall survival (OS) were excellent at a median of 46.4 months and 72+ months. There was a trend towards an improved PFS in patients with an immunofixation-negative CR compared with patients with a PR (49.4 months, 41.14 months; P = 0.26). This was not evident when electrophoresis was used to define CR. The method used to define CR did not impact on the overall survival and fluorescent IgH PCR failed to add any additional prognostic information. This study supports the widespread use of the European Bone Marrow Transplantation group (EBMT) response criteria and suggests that immunofixation should be performed on all patients who become electrophoresis negative.

Radiation-associated pneumonitis following autologous stem cell transplantation: predictive factors, disease characteristics and treatment outcomes.
    Bone marrow transplantation, 2001, Volume: 27, Issue:2

    High-dose therapy followed by autologous stem cell transplantation (ASCT) prolongs survival in patients with multiple myeloma and is relatively safe with treatment-related mortality rates of only 1-5%. Interstitial pneumonitis (IP) is normally an infrequent complication of ASCT with a reported incidence of 0-16%. Between 1992 and 1998, 94 myeloma patients at our center underwent ASCT using a high-dose regimen of etoposide (60 mg/kg), melphalan (160 mg/m2) and fractionated TBI 12 Gy. An unusually high incidence of IP (29/94 (31%)) was noted. Mortality in the IP patients was high at 45%. Patients developing IP were more frequently anemic than those who did not have pulmonary complications (hemoglobin <100 g/l) prior to transplant (P = 0.03) but no other pre-transplant factors were predictive (ie age, gender, smoking history, CMV status, pulmonary function, creatinine, beta2-microglobulin or C-reactive protein, prior cumulative chemotherapy or chest irradiation). A significantly lower IP rate was noted in 32 contemporaneous myeloma control patients conditioned with BU-CY without TBI at our center (3/32 (9%); P=0.03) and in 32 lymphoma control patients conditioned with the same melphalan and etoposide regimen minus the TBI (2/32 (6%); P = 0.003). In contrast, when using the same TBI-containing regimen in 32 concurrently treated lymphoma patients, an increase in IP similar to that seen in our myeloma cohort (7/32 (22%); P = 0.3) was noted. This strongly suggests that TBI is the predominant factor contributing to lung toxicity. We conclude that radiation-associated pneumonitis cannot be easily predicted by pretransplant variables. Therefore surveillance, early recognition and prompt therapy are recommended.

Satisfactory remission in a case of IgD myeloma: effectiveness of glucocorticoid treatment.
    American journal of hematology, 2001, Volume: 66, Issue:1

    IgD myeloma is an infrequent type of multiple myeloma and is characterized by an aggressive clinical behavior and a short survival time. No satisfactory treatments have thus far been established. Recently we treated a patient with IgD(lambda)-type myeloma with glucocorticoids, and succeeded in achieving a complete remission. This case seems to indicate a usefulness of glucocorticoid monotherapy for treating IgD myeloma.

Glomerular filtration rate prior to high-dose melphalan 200 mg/m(2) as a surrogate marker of outcome in patients with myeloma.
    British journal of cancer, 2001, Aug-03, Volume: 85, Issue:3

    We correlated age and body surface area corrected glomerular filtration rate (GFR) at the time of high-dose melphalan (HDM) administration with treatment-related toxicity (TT), time to disease progression and survival. Between 8/85 and 6/98, 144 newly diagnosed myeloma patients with a median age of 53 years (range, 31-72) received infusional chemotherapy with vincristine, doxorubicin and methylprednisolone, with/without cyclophosphamide or verapamil, followed by HDM 200 mg/m(2)and stem cell rescue. An additional patient received HDM at diagnosis. GFR was below normal in 38 patients (26%). At presentation, patients with low GFR at the time of HDM had higher serum creatinine, beta(2)M, stage III disease, calcium and Bence-Jones proteinuria. Toxic deaths post-HDM were similar in both groups (2/38 (5%) vs. 4/107 (4%)), though patients with low GFR had more oral mucositis (P< 0.0001), diarrhoea (P = 0.005) and infections (P = 0.04). The response and relapse rates of the 2 groups were not substantially different, but the median overall survival (OS) was significantly shorter in patients with low GFR (5.1 vs 7.5 years, P = 0.015). Multivariate analysis showed that a normal GFR and being in CR at the time of HDM were predictive of longer OS. We conclude that in context of high-dose chemotherapy for myeloma, dose of melphalan should not be modified in patients with low GFR and that early intensive treatment at relapse may improve results in patients with abnormal renal function.

The effects of prior induction therapy with melphalan on subsequent peripheral blood progenitor cell transplantation for myeloma.
    Clinical and laboratory haematology, 2001, Volume: 23, Issue:2

    High dose chemoradiotherapy with autologous peripheral blood progenitor cell transplantation (PBPCT) may improve outcome in myeloma. Melphalan is an effective drug in the treatment of myeloma, but is potentially toxic to progenitor cells. We studied 8 patients receiving intermittent intravenous melphalan (25 mg/m2) as induction therapy before PBPCT to assess engraftment characteristics post-transplantation. Comparison was made with an age-matched control group of patients with non-Hodgkins lymphoma who had not received melphalan during induction therapy. There was correlation (P=0.037) between the dose of melphalan per kg body weight given, premobilization, and days to neutrophil engraftment, but no significant difference between the two groups in neutrophil recovery. The study group had delayed platelet recovery (P=0.01) and required more platelet support post-transplantation (P=0.05). 3-4 weekly melphalan (25 mg/m2) up to 6 courses was delivered to patients who went on to PBPCT without significantly influencing neutrophil recovery but with a negative impact on platelet recovery.

Acute left ventricular failure following melphalan and fludarabine conditioning.
    Bone marrow transplantation, 2001, Volume: 28, Issue:1

    Cardiotoxicity has rarely been reported as a complication of melphalan or fludarabine administration as single agents. Recently, melphalan and fludarabine have been used in combination as non-myeloablative conditioning chemotherapy prior to allogeneic stem cell transplantation. We have observed the development of severe left ventricular failure in three of 21 patients treated with this combination. Cardiotoxicity in this context has not previously been reported and has implications for the assessment, monitoring and treatment of patients undergoing pre-transplant conditioning with melphalan and fludarabine.

Autologous stem cell transplantation in elderly multiple myeloma patients over the age of 70 years.
    British journal of haematology, 2001, Volume: 114, Issue:3

    The feasibility and efficacy of autologous stem cell transplantation (auto-SCT) in patients aged > or = 70 years was analysed. Newly diagnosed (n = 34) and refractory multiple myeloma (n = 36) patients were studied. The median age was 72 years (range: 70-82.6). CD34+ cells were mobilized with chemotherapy and granulocyte colony-stimulating factor (G-CSF) (n = 35) or G-CSF alone (n = 35), yielding medians of 11.8 x 10(6) versus 8 x 10(6) cells/kg respectively (P = 0.007). Because of excessive mortality (16%) in the first 25 patients who received melphalan 200 mg/m2 (MEL-200), the dose was subsequently decreased to 140 mg/m2 (MEL-140). Median times to absolute neutrophil count (ANC) > 0.5 x 10(9)/l and to platelets > 20 x 10(9)/l were 11 and 13 d respectively. Thirty-one patients (44%) received tandem auto-SCT. Complete remission (CR) was 20% after the first SCT and 27% after tandem SCT. Median CR duration was 1.5 years and was significantly longer for patients with < or = 12 months of prior chemotherapy (2.6 versus 1.0 years, P = 0.0008). The 3-year event-free survival (EFS) and overall survival (OS) (+ standard error, SE) were projected at 20% + 9% and 31% + 10% respectively. Tandem SCTs positively affected EFS (4.0 versus 0.7 years; P = 0.003) and OS (4.0 versus 1.4 years; P = 0.02) compared with single auto-SCT. In conclusion, MEL-140 is less toxic and appears equally as efficacious as MEL-200 in elderly patients. The benefits of tandem SCT in this patient population need further evaluation in a randomized trial.

Retrolective cohort study of an additive therapy with an oral enzyme preparation in patients with multiple myeloma.
    Cancer chemotherapy and pharmacology, 2001, Volume: 47 Suppl

    To evaluate the impact of an additive therapy with an oral enzyme (OE) preparation given for more than 6 months additionally to standard combination chemotherapy (vincristine/melphalan/cyclophosphamide/prednisone (VMCP)- or methylprednisolone/ vincristine/CCNU/cyclophosphamide/melphalan (MOCCA)-regimen) in the primary treatment of patients with multiple myeloma stages I-III.. A cohort of 265 patients with multiple myeloma stages I-III was consecutively treated at our institution in two parallel groups (control group (n = 99): chemotherapy +/-OE for less than 6 months; OE-group (n = 166): chemotherapy + OE for more than 6 months). The median follow-up time in the stages I, II, and III for the OE-group was 61, 37, and 46.5 months, respectively; for the control group the respective values were 33, 51.5, and 31.5 months. The primary endpoint of the study was disease-specific survival. Secondary endpoints were response to therapy, duration of first response and side effects. The chosen method for evaluation was the technique of a retrolective cohort analysis with a concurrent control group. Survival analysis was performed by the Kaplan-Meier method and multivariate analysis was done with the Cox proportional hazards model.. Significantly higher overall response rates and longer duration of remissions were observed in the OE-group. Primary responders showed a longer mean survival time than non-responders. Additive therapy with OE given for more than 6 months decreased the hazard of death for patients at all stages of disease by approximately 60%. Observation time was not long enough to estimate the median survival for patients at stages I and II; for stage III patients it was 47 months in the control group versus 83 months for the patients treated with OE (P = 0.0014) which means a 3-year gain of survival time. Significant prognostic factors for survival, in the Cox regression analysis, were stage of disease and therapy with OE. The OE-therapy was generally well tolerated (3.6% of patients with mild to moderate gastrointestinal symptoms).. OEs represent a promising new additive therapy in multiple myeloma which will be further evaluated in a randomized phase III trial in the USA.

Results of autologous stem cell transplant in multiple myeloma patients with renal failure.
    British journal of haematology, 2001, Volume: 114, Issue:4

    Data are presented on 81 multiple myeloma (MM) patients with renal failure (creatinine > 176.8 micromol/l) at the time of autologous stem cell transplantation (auto-SCT), including 38 patients on dialysis. The median age was 53 years (range: 29-69) and 26% had received more than 12 months of prior chemotherapy. CD34+ cells were mobilized with granulocyte colony-stimulating factor (G-CSF) alone (n = 51) or chemotherapy plus G-CSF (n = 27), yielding medians of 10 and 16 x 106 CD34+ cells/kg respectively (P = 0.003). Sixty patients (27 on dialysis) received melphalan 200 mg/m2 (MEL-200). Because of excessive toxicity, the subsequent 21 patients (11 on dialysis) received MEL 140 mg/m2 (MEL-140). Thirty-one patients (38%) completed tandem auto-SCT, including 11 on dialysis. Treatment-related mortality (TRM) was 6% and 13% after the first and second auto-SCT. Median times to absolute neutrophil count (ANC) > 0.5 x 109/l and to platelets > 50 x 109/l were 11 and 41 d respectively. Non-haematological toxicities included mucositis, pneumonitis, dysrhythmias and encephalopathy. At a median follow up of 31 months, 30 patients have died. Complete remission (CR) was achieved in 21 patients (26%) after first SCT and 31 patients (38%) after tandem SCT. Two patients discontinued dialysis after SCT. Median durations of complete remission (CR) and overall survival (OS) have not been reached; probabilities of event-free survival (EFS) and OS at 3 years were 48% and 55% respectively. Dialysis dependence and MEL dose did not affect EFS or OS. Sensitive disease prior to SCT, normal albumin level and younger age were independent prognostic factors for better OS. In conclusion, renal failure had no impact on the quality of stem cell collections and did not affect engraftment. MEL-140 had an acceptable toxicity and appeared equally effective as MEL-200. In the setting of renal failure, the role of auto-SCT early in the disease course and benefits of tandem SCT require further evaluation.

    Tidsskrift for den Norske laegeforening : tidsskrift for praktisk medicin, ny raekke, 2001, Aug-30, Volume: 121, Issue:20

    Since the introduction of the simple cyclic oral treatment with melphalan and prednisone in the late 1960s, there has been no substantial improvement in the therapy of multiple myeloma. In 1994, the Nordic Myeloma Study Group initiated a population-based, prospective study to evaluate the impact on survival of high dose chemotherapy in newly diagnosed, symptomatic patients under 60 years of age, compared to a conventionally treated control group.. 274 patients were treated according to a specified high dose protocol and compared to 274 patients from previous population-based trials fulfilling the same eligibility criteria.. Median survival was 44 months in the control group and 62 months in the intensive treatment group (risk ratio 1.65; 95% CI = 1.28-2.14, P = 0.0001). A study of health-related quality of life (HRQoL) which was integrated in the trial showed a moderately reduced HRQoL associated with the intensive treatment phase, but no statistically significant difference beyond the first year of follow-up. In a cost-utility analysis of the trial, the cost per (quality-adjusted life years) was estimated at USD 26,000.. The incremental cost of the treatment is within what is usually thought to be acceptable limits. Further improvement of the results and reduction of stay in hospital would give an even more favourable cost-utility ratio.

    This article summarizes the different clinical results of the IFM trials: high dose therapy supported with autologous stem cells improves survival, melphalan 200 mg/m2 is the best preparative regimen, unpurged peripheral blood stem cells are the recommended source of stem-cells to support high dose therapy, tandem transplants significantly improve survival. However, despite these encouraging results, long term survival needs inovative strategies evaluated with the current IFM 99 protocol.

Immunomodulation of early engrafted natural killer cells with interleukin-2 and interferon-alpha in autologous stem cell transplantation.
    Bone marrow transplantation, 2001, Volume: 28, Issue:7

    High relapse rates during the first year after autologous stem cell transplantation (ASCT) for multiple myeloma or non-Hodgkin lymphoma are due to the failure of high-dose chemotherapy to eradicate minimal residual disease. Post-ASCT immunorecovery studies have shown that quantities of natural killer (NK) cells return to normal within 1 month post-ASCT in contrast to the recovery of T and B cell populations (up to 1 year). Preclinical studies have demonstrated that NK cells have potent antitumor activity. IL-2 and IFN-alpha enhance NK-cell activity. We investigated the efficacy of IL-2 and IFN-alpha to up-regulate NK-cell cytotoxicity at 14 days post ASCT. Twenty patients undergoing ASCT had PBMCs collected pretransplantation and at 14 days post transplantation. PBMCs (effector cells) from each blood sample were incubated in vitro with IFN-alpha and IL-2 at 10000 IU/ml. NK cell activity was determined by sodium chromate (51)Cr release assay for lysis of K562 target cells. IL-2 and IFN-alpha each increased lysis of K562 cells compared with placebo (effector-to-target ratio, 50:1, P < 0.001). Increased NK cell activity occurred in samples from all patients. IL-2 and IFN-alpha up-regulated NK cell activity at 14 days post ASCT. They may be useful as immunomodulators as early as 14 days post ASCT to eradicate or control minimal residual disease.

Predictive factors for a successful mobilization of peripheral blood CD34+ cells in multiple myeloma.
    Annals of hematology, 2001, Volume: 80, Issue:10

    We analyzed the prognostic factors for a successful mobilization and peripheral blood stem cell collection in a series of 57 consecutive patients with multiple myeloma (MM); a new scoring system to predict an adequate mobilization in this subset of patients was also constructed. A total of 221 aphereses were performed in 57 patients with MM. The median time from diagnosis to mobilization was 12 months (range 4-120). Only one line of chemotherapy was administered before mobilization to 36 patients and two or more to 21. The median number of alkylating chemotherapy cycles was 6 (2-33). Two patients were mobilized in complete remission, 32 in partial response, and 23 in stable/progressive disease. Significant adverse prognostic factors for collecting 2.5 x 10(6) CD34+cells/kg or more were: a period of at least 12 months from diagnosis, at least six cycles of alkylating agents, and a plasma cell infiltration of 20% or more prior to mobilization. Patients with three risk factors had a probability of only 0.38 (95% CI 0.3-0.9) for adequate mobilization. Ten patients failed to mobilize; a period from diagnosis of 12 months or more and female sex were unfavorable factors. Patients with two risk factors had a probability of 0.50 (95% CI 0.2-0.8) for failing the mobilization procedure. These findings indicate that MM patients must be mobilized early in the course of the disease, with minimal disease burden before severe hematopoietic progenitor cell injury due to cumulative therapy.

Engraftment, clinical, and molecular follow-up of patients with multiple myeloma who were reinfused with highly purified CD34+ cells to support single or tandem high-dose chemotherapy.
    Blood, 2000, Apr-01, Volume: 95, Issue:7

    Eighty-two patients with advanced multiple myeloma (MM) were enrolled in 2 sequential clinical studies of 1 or 2 courses of myeloablative therapy with stem cell support. Conditioning regimens consisted of high-dose melphalan (MEL) with or without total body irradiation (TX1 = 35) and MEL as the first preparative regimen, followed within 6 months by busulfan and melphalan (TX2 = 47). On the basis of adequate stem cell harvest, 31 patients (TX1 = 13; TX2 = 18) were transplanted with highly purified CD34+ cells. Positively selected stem cells did not adversely affect hematopoietic reconstitution compared with unmanipulated peripheral blood stem cell. Overall, the complete remission (CR) rate of evaluative patients was 13.8% and 41% for single and double autotransplant, respectively (P =.04). Moreover, 3 patients undergoing TX2 achieved molecular remission and 2 remain PCR-negative after 36 and 24 months from autograft. The median event-free survival (EFS) durations for TX1 and TX2 were 17 and 35 months, respectively (P =.03). Actuarial 3-year overall survival for patients treated with 1 or 2 transplants are 76% and 92%, respectively (P = NS). On multivariate analysis, superior EFS was associated with low beta2 microglobulin (beta2-M) level at diagnosis and TX2, whereas overall survival was correlated with beta2-M. Positive selection of CD34+ cells did not influence the achievement of clinical or molecular CR, as well as remission duration or survival of MM patients. Thus, whereas multiple cycles of high-dose therapy may be beneficial for patients with myeloma, the clinical impact of tumor cell purging remains highly questionable.

Dose-intensive melphalan with stem cell support (CM regimen) is effective and well tolerated in elderly myeloma patients.
    Haematologica, 2000, Volume: 85, Issue:5

    Multiple myeloma (MM) typically afflicts elderly patients. High-dose therapy has recently been shown to lead to a better outcome than standard treatment, mainly in younger patients. The extent to which older subjects can benefit from intensified approaches without excessive toxicity is examined in this study.. Between December 1994 and May 1997, 12 Italian Multiple Myeloma Study Group institutions entered 68 patients at diagnosis (median age 65) into an intensified chemotherapy regimen: cyclophosphamide (CY) 3 g/m(2) plus melphalan 60 mg/m(2) followed by peripheral blood progenitor cells (PBPC) and G-CSF (CM regimen). CY (day 0) and G-CSF were used to mobilize PBPC harvested by a single leukapheresis on day 10. Melphalan was infused on day 11. PBPC were kept unprocessed at 4 degrees C for 48 hours and reinfused on day 12. Three CM regimens were delivered at 6-month intervals.. Sufficient PBPC to support the first CM cycle were available (median CD34(+) harvest: 4.9x10(6)/kg), but dropped significantly after the second (median CD34(+) harvest: 2x10(6)/kg) and the third (median CD34(+) harvest: 0.9x10(6)/kg). The median durations of severe neutropenia (absolute neutrophil count < 500 microL) were 3, 4, and 3 days, and those of severe thrombocytopenia (platelets < 25,000/microL) were 2.5, 2, and 1 days, after the first, second and third courses, respectively. The frequency of extramedullary toxicities was low. Treatment-related mortality (TRM) was 3% after the first CM, only. Complete remission (CR) was 14% after the first, 16% after the second and 27% after the third CM. After a median follow-up of 34 months (range 19-49 months), median event-free survival was 35.6 months.. These results indicate that dose-intensity of melphalan can be increased by reinfusing PBPC with acceptable low toxicity. The combination of CY and melphalan followed by PBPC is an effective chemotherapy for elderly myeloma patients. Repeated melphalan infusion hampered subsequent CD34(+) harvests.

Myelomatous effusion with poor response to chemotherapy.
    Journal of Korean medical science, 2000, Volume: 15, Issue:2

    While pleural effusion in multiple myeloma is relatively infrequent, myelomatous pleural effusion is extremely rare. We experienced a 61-year-old woman with IgD-lambda multiple myeloma and pleural effusion. The diagnosis was made originally by pleural biopsy, pleural fluid cytology and immunoelectropheresis of pleural fluid. Transient improvement of the pleural effusion was observed after administration of combination chemotherapy of vincristine, melphalan, cyclophosphamide, prednisone (VMCP)/vincristine, cyclophosphamide, adriamycin, prednisone (VCAP). Two months later, myelomatous pleural effusion recurred and no response to salvage therapy was observed. We reviewed the clinical feature of this case and literature concerning myelomatous pleural effusion.

Infusion of lymphocytes obtained from a donor immunised with the paraprotein idiotype as a treatment in a relapsed myeloma.
    Bone marrow transplantation, 2000, Volume: 25, Issue:10

    A 48-year-old patient with IgA k multiple myeloma received a BMT from his HLA-matched sibling. After transplantation, the disease relapsed. Melphalan therapy followed by reinfusion of haemopoietic blood stem cells collected from the patient led to the improvement of the clinical status, although mixed chimerism and an elevated serum IgA persisted. Successful donor immunisation against an immunogenic preparation of the recipient monoclonal protein was performed before the infusion of donor T lymphocytes (DLI) into the patient. Ten weeks after the lymphocyte infusions, no monoclonal band was evidenced and donor complete chimerism was detected. The patient did not develop GVHD. Once complete remission was achieved, the idiotype vaccine was administered to the patient. Nineteen months after DLI, the patient remains in remission. Bone Marrow Transplantation (2000).

Treatment of deep vein thrombosis using temporary vena caval filters after allogeneic bone marrow transplantation.
    Leukemia & lymphoma, 2000, Volume: 38, Issue:3-4

    Bone marrow transplant (BMT) recipients have risk factors for deep vein thrombosis (DVT) including venous stasis caused by immobilization in the sterile unit, vessel wall damage caused by preparative regimen or indwelling catheters, and hypercoagulability caused by decreased natural anticoagulants. We successfully treated a patient who developed massive DVT in the superior vena cava after BMT with anticoagulation and the use of temporary vena caval filters. Considering the delayed complications, permanent filter is not appropriate for BMT recipients, because the risk factors for DVT associated with BMT are transient. We considered that temporary vena caval filter is a safe and useful device to prevent pulmonary embolism after DVT in BMT recipients.

Severe amyloidosis with mild multiple myeloma--an unusual course.
    Haematologia, 2000, Volume: 30, Issue:1

    Amyloidosis may be primary or myeloma-associated. Skeletal lesions and the percentage of bone marrow plasma cells (<10% in primary, >20% in myeloma) account for the major differences between the two varieties. In the literature there are rare cases of primary amyloidosis presenting without myeloma and followed by development of myelomatous manifestations. Usually, the primary disease (i.e. the myeloma) is advanced, when amyloidosis is diagnosed. We describe a patient who had presented with a severe and progressive systemic amyloidosis and was diagnosed later to have a mild light chain myeloma. Aggressive treatment with melphalan, prednisone and colchicine resulted in a temporary partial remission, followed by a rapid downhill course, and the patient's death. The point of relatively mild myeloma following a rapidly progressive course of advanced amyloidosis is emphasized. Awareness of the possibility of such a combination may lead to early diagnosis, a more aggressive or novel therapeutic approach and, possibly, to a better prognosis.

    Pleural effusion caused by plasma cell involvement in multiple myeloma has been reported unfrequently, and has been described at a frequency below 1% of multiple myeloma. In this study, we report an observation with pleural effusion as first symptom of multiple myeloma. The analysis of the pleural liquid showed plasma cells with a monoclonal IgG Kappa immunoglobulin. In addition, there was a bone marrow infiltration by plasma cells, a serum monoclonal immuno-globulin of the same type and osteolytic lesions. Our patient has received one course of chemotherapy with: vincristine, melphalan, cyclophosphamide and prednisone. The patient did not respond to the therapy and died one month later. Pleural effusion seems to be an expression of aggressive myeloma. Survival exceeds rarely 4 months.

Reactive plasmacytoses in multiple myeloma during hematopoietic recovery with G- or GM-CSF.
    Leukemia research, 2000, Volume: 24, Issue:7

    We report on three cases of reactive plasmacytoses (RP) in the course of multiple myeloma (MM). The three patients achieved complete remission following high dose melphalan and peripheral blood stem cell transplantation. These transient plasmacytoses had all the characteristics of RP, i.e. expansion of highly proliferative polyclonal plasma cells (PC) with a normal phenotype and genotype and corresponding to expansion of both PC progenitors (plasmablasts) and PC precursors (early plasma cells). These cells were easily distinguished from malignant PC of the corresponding patients evaluated at diagnosis, especially by their phenotypic and genotypic features.

Expression of BAX in plasma cell dyscrasias.
    Clinical cancer research : an official journal of the American Association for Cancer Research, 2000, Volume: 6, Issue:6

    Several studies demonstrate that the BCL-2 and BCL-XL antiapoptotic genes are variably expressed in plasma cells of patients with multiple myeloma (MM). However, the plasma cell expression of BAX protein, their major proapoptotic partner, has not been investigated. Our initial Western blot analysis of myeloma cell extracts also suggested patient variability in the expression of BAX, which was not altered by exposure to interleukin 6. To further investigate the significance of BAX expression, we performed immunohistochemistry on archival bone marrow biopsies and compared BAX staining to BCL-2 immunostaining. Expression was first evaluated in 104 patients with reactive plasmacytosis, monoclonal gammopathy of undetermined significance/smoldering MM, or active MM. An increase (P < 0.05) in expression of both BAX and BCL-2 was detected in MM patients compared with patients with reactive plasmacytosis. Patients with monoclonal gammopathy of undetermined significance/smoldering MM had intermediate values. For correlations with outcome, expression was assessed in 43 patients at diagnosis who were treated with melphalan and prednisone; 30 at diagnosis who were treated with vincristine, Adriamycin, and dexamethasone; and 29 at relapse who were treated with second-line therapy. There was no correlation between BAX or BCL-2 expression and response to chemotherapy or duration of response or between BCL-2 expression and survival. However, patients who demonstrated extremely low plasma cell BAX expression had significantly increased survival. This was true for patients initially treated with melphalan and prednisone or vincristine, Adriamycin, and dexamethasone, as well as patients studied at relapse. BAX expression did not correlate with expression of proliferating cell nuclear antigen used as a marker of proliferation. These data indicate a myeloma-specific increase in BAX expression in plasma cells and suggest that low BAX expression identifies a cohort of patients with long survival, which is not specifically associated with low proliferating cell nuclear antigen expression.

Safety of autologous hematopoietic stem cell transplantation in patients with multiple myeloma and chronic renal failure.
    Leukemia, 2000, Volume: 14, Issue:7

    Patients with multiple myeloma (MM) and chronic renal failure have generally been excluded from myeloablative therapy programs followed by hematopoietic stem cell support because of the potential increase in transplant-related morbidity and mortality. We here report our experience treating six MM patients with moderate to severe renal insufficiency, with autologous stem cell transplantation. One of these patients required chronic hemodialysis since the diagnosis of MM was made. Peripheral blood stem cell collection was performed with either cyclophosphamide 5.5-7 g/m2 + G-CSF, 5 microg/kg/day (patients 1-3, 5 and 6) or G-CSF, 15 microg/kg/day alone (patient No. 4). Four patients (Nos 1-4) received autotransplant as front-line therapy, while the last two patients were treated in relapse, which occurred following prior autologous stem cell transplantation in support of melphalan, 200 mg/m2 (No. 5) or maintainance therapy with alpha-interferon (No. 6). High-dose chemotherapy administered as preparation to transplant included busulfan 12 mg/kg + melphalan 80 mg/m2 (patients 1-3 and 6) or melphalan 80 mg/m2 alone (patients 4 and 5) in order to reduce mucosal damage. Following transplant, prompt and sustained recovery of hematopoiesis was documented in all the patients; 500 PMN/microI and 20000 platelets/microI were reached after a median of 13 and 14 days, respectively. None of the patients suffered from WHO grade 3-4 infectious complications. Transplant-related toxicity included grade 3-4 oral mucositis (patients 1, 4 and 5) and veno-occlusive disease (patient No. 3). Renal function either improved or remained stable throughout the transplant period. All the patients but one responded to therapy, three of them are progression free after 2, 15 and 26 months; two relapsed after 16 and 4 months and one died from cholangiocarcinoma 7 months after transplant, while still in remission. Although our experience is limited so far, these results appear promising and support the investigational use of myeloablative therapy in MM patients with chronic renal failure.

Down-regulation of CD98 in melphalan-resistant myeloma cells with reduced drug uptake.
    Acta haematologica, 2000, Volume: 103, Issue:3

    Although melphalan has been used as a therapeutic reagent for multiple myeloma, many patients become refractory. To elucidate the mechanism of resistance to melphalan, we generated a melphalan-resistant myeloma cell line, KHM-11(EMS), by treating a parental line, KHM-11, with a mutagen, ethylmethanesulfonate. KHM-11(EMS) is 55 times more resistant to melphalan. gamma-Glutamylcysteine synthetase, P-glycoprotein, multidrug-resistance-associated protein, lung-resistance-related protein and the Bcl-2 family of proteins were not responsible for the drug resistance in KHM-11(EMS). Intracellular incorporation of melphalan to myeloma cells was determined by using [(14)C]-labeled melphalan. Accumulation of melphalan in KHM-11(EMS) was 43% of KHM-11, while the efflux rates were comparable in both cell lines. The uptake of melphalan was inhibited by the addition of L-phenylalanine, indicating that melphalan is incorporated through the L-phenylalanine transporter as reported previously. Expression of CD98, which was recently cloned as an L-phenylalanine transporter, was 6-fold decreased in KHM-11(EMS), suggesting that CD98 may be correlated with the incorporation of melphalan. CD98 expression and incorporation of melphalan were analyzed in fresh purified myeloma cells from 5 patients. All myeloma cells from 4 cases expressed CD98 at a high level and incorporated melphalan. However, tumor cells from 1 case expressed CD98 at low levels and did not incorporate melphalan. Taken together, reduced melphalan uptake could be responsible for the drug resistance in KHM-11(EMS), and down-regulation of CD98 may be related to this phenomenon. Further investigation of the correlation between impaired drug uptake and down-regulation of CD98 in myeloma cells should be important to understand the mechanism of resistance to melphalan.

Donor lymphocyte infusions for relapsed multiple myeloma after allogeneic stem-cell transplantation: predictive factors for response and long-term outcome.
    Journal of clinical oncology : official journal of the American Society of Clinical Oncology, 2000, Volume: 18, Issue:16

    To determine the efficacy, toxicity, and long-term outcome and prognostic factors of donor lymphocyte infusions (DLI) in patients with relapsed multiple myeloma (MM) after allogeneic stem-cell transplantation (AlloSCT).. Twenty-seven patients received 52 DLI courses at a median of 30 months after the previous AlloSCT. Reinduction therapy was administered to 13 patients before DLI.. Reinduction therapy was successful in eight of 13 patients. Fourteen patients (52%) responded to DLI, including six patients (22%) who achieved a complete remission (CR). Five patients responded after T-cell dose escalation in subsequent DLIs. Four patients experienced relapse or disease progression (three from partial response and one from CR). Five patients remain in remission more than 30 months after DLI. Major toxicity was acute and chronic graft-versus-host disease (GVHD), which was present in 55% and 26% of patients, respectively. Two patients died from bone marrow aplasia. Median overall survival of all patients was 18 months. Overall survival was 11 months for DLI-resistant patients and has not been reached for the responding patients. In two patients, sustained molecular remission was observed. The factors that were correlated with response to DLI were a T-cell dose of more than 1.10(8) cells/kg, response to reinduction therapy, and chemotherapy-sensitive disease before AlloSCT.. These data confirm the potential and durable graft-versus-myeloma effect of DLI in patients with relapsed MM after AlloSCT. Future studies should be aimed at increasing response rates, especially in patients with chemoresistant disease, and reducing toxicity by limiting GVHD. Adjuvant DLI seems an attractive and promising approach for patients who do not achieve a molecular remission after AlloSCT.

Acute leukaemia and other secondary neoplasms in patients treated with conventional chemotherapy for multiple myeloma: a Finnish Leukaemia Group study.
    European journal of haematology, 2000, Volume: 65, Issue:2

    The occurrence of acute leukaemia and other secondary neoplasms in 432 patients treated with conventional chemotherapy for multiple myeloma was analysed after a follow-up period of 11-19 yr (mean 16 yr). The number and organ-specific distribution of observed solid neoplasms was close to that expected in the general population. Non-Hodgkin's lymphoma developed in three patients (expected 0.7, p = 0.19). Acute leukaemia was diagnosed in 14 patients with an actuarial risk of 9.8% at 9 yr. No further cases were diagnosed thereafter. The average numbers of courses (26.2 vs. 25.5) and cumulative doses of melphalan (1440 and 1400 mg) were similar in patients with or without acute leukaemia. It seems possible that the advanced stage of multiple myeloma is more vulnerable to the leukaemogenic effect of melphalan compared with the earlier stages.

Hyperammonemia after high-dose chemotherapy and stem cell transplantation.
    Bone marrow transplantation, 2000, Volume: 26, Issue:3

    We report a patient with multiple myeloma who suffered from hyperammonemia after a second stem cell autograft. This syndrome is not well known but is associated with a high mortality rate. Considering the possibility of this diagnosis in patients developing confusion and neurological degradation with respiratory alkalosis after intensive chemotherapy, could allow earlier treatment and perhaps improved survival. Possible mechanisms and potential therapies are discussed. With rapid recognition and treatment of the syndrome, the patient fully recovered. One and a half years later, she is still alive and well, on interferon for persisting myeloma.

Intravenous melphalan and dexamethasone followed by lymphoblastoid alpha interferon in higher risk multiple myeloma patients.
    Leukemia & lymphoma, 2000, Volume: 39, Issue:1-2

    Intermittent courses of melphalan and prednisone is still the standard chemotherapy for the initial treatment of multiple myeloma (MM) in patients who cannot undergo high-dose chemotherapy/radiotherapy with either allogeneic or autologous stem cell transplantation. However, the absorption of the drug from the gastrointestinal tract is highly variable from patient to patient and therefore, different plasma levels of the drug are reached in the blood of individual MM patients. In order to overcome this limitation we decided to use intermediate dose (15-30 mg/m2, day 1) intravenous melphalan in resistant or relapsing MM patients as well as in untreated patients not eligible for a more aggressive protocol. Moreover, considering the good results obtained by other investigators using dexamethasone alone or associated with interferon in the treatment of resistant or relapsing MM patients, dexamethasone (40 mg total dose, day 1) and the lymphoblastoid alpha interferon (3 MU, 3 times a week x 3 weeks, from day 8 to day 26 of each course) were added to intravenous melphalan. Courses were repeated every 5 weeks for a total of 6 cycles. We treated 62 MM patients obtaining a response (defined as reduction > 25% of the initial monoclonal component value associated with disappearance of the clinical symptoms) in 38 out 62 evaluable patients (61%) and stable disease (defined as a decrease of < 25% in the base-line serum monoclonal component level with disappearance of all symptoms present at diagnosis) in 9 (14.5%) more patients. The overall median response duration was 14 months and the overall median survival duration (from the time of inclusion in this protocol) for the 62 patients entered into the study was 34 months. No severe (Grade 3-4 of the WHO) hematological as well as non hematological toxicities were observed. This lack of severe toxicity allowed us to administer the drugs on an outpatient basis. In conclusion, the overall response and the low grade of toxicity in this category of patients are encouraging and suggest that this protocol is both effective and safe treatment for high risk MM patients.

[Aggressive transformation and extramedullary tumor formation in IgA-lambda multiple myeloma].
    [Rinsho ketsueki] The Japanese journal of clinical hematology, 2000, Volume: 41, Issue:8

    A 52-year-old woman complained of lower back pain and gluteal pain in April 1997, and was found to have anemia, hypercalcemia and renal disorder. In September of the same year, she was diagnosed as having IgA-lambda myeloma (stage IIIA). VMMD-IFN therapy was started in November, 1997, and this resulted in improvement of the M-protein level, and relief of the pain in the lower back and gluteal region. A second course of VMMD-IFN therapy was also effective. In April 1998, however, the back pain worsened, and in July the patient suffered a fall and fractured her left femur. Upon readmission to our hospital, the level of M-protein was lower, and high fever, hypercalcemia, renal disorder, elevation of the LDH level, anemia and thrombocytopenia were observed. Bone marrow examination revealed 30% atypical large-sized CD19-, CD38+, CD56+ myeloma cells and chromosomal abnormalities. Although the symptoms were improved temporarily after a third course of VMMD therapy, disease aggravation occurred again, and extramedullary masses appeared on the head, face and pelvis. VAD therapy was performed without effect, and the patient died about 2 months after recurrence. This was a comparatively rare case of fulminant multiple myeloma occurring in the terminal stage.

Biochemical markers of bone turnover following high-dose chemotherapy and autografting in multiple myeloma.
    Blood, 2000, Oct-15, Volume: 96, Issue:8

    The effect of high-dose chemotherapy and autografting on bone turnover in myeloma is not known. A study of 32 myeloma patients undergoing blood or marrow transplant (BMT), conditioned with high-dose melphalan, was done. Bone resorption was assessed by urinary free pyridinoline (fPyr) and deoxypyridinoline (fDPyr), expressed as a ratio of the urinary creatinine concentration. Bone formation was assessed by serum concentration of procollagen 1 extension peptide (P1CP) and bone-specific alkaline phosphatase (BSAP). Eighteen cases had normal fPyr and fDPyr at transplant, and in all but one of these cases the level remained normal throughout subsequent follow-up. In contrast, in 14 cases urinary fPyr and fDPyr levels were increased at transplant. In these cases, both fPyr and fDPyr fell to normal levels over the next few months (P = .0009 and.0019, respectively). fPyr and fDPyr levels at transplant and their trends post-BMT were unrelated to the use of pre-BMT or post-BMT bisphosphonate or post-BMT interferon. Nine cases had elevated P1CP or BSAP at transplant, which rapidly normalized. In most patients there was an increase in P1CP and/or BSAP several months post-transplant. In conclusion, increased osteoclast activity may be present even in apparent plateau phase of myeloma. High-dose chemotherapy with autografting may normalize abnormal bone resorption, although the effect may take several weeks to emerge and may be paralleled by increased osteoblast activity. The findings provide biochemical evidence that autografting may help normalize the abnormal bone turnover characteristic of myeloma. (Blood. 2000;96:2697-2702)

Cellular biological differences between human myeloma cell lines KMS-12-PE and KMS-12-BM established from a single patient.
    International journal of hematology, 2000, Volume: 72, Issue:2

    To clarify cellular biological varieties of myeloma cells, biological differences were analyzed between 2 human myeloma cell lines, KMS-12-PE and KMS-12-BM, derived from pleural effusion and bone marrow, respectively, of a single patient. Although both lines were considered to be derived from the same clone because both had the same chromosomal marker and immunoglobulin H rearrangement, several biological differences were noted. CD11a and CD20 were highly expressed in the KMS-12-BM line, whereas the KMS-12-PE line showed a higher expression of CD7 and CD95/Fas. Although growth was stimulated in KMS-12-BM by interleukin-6 and interferon-alpha, it was inhibited in KMS-12-PE. In addition, apoptosis inhibitors Bcl-2 and Bcl-X(L) were highly expressed in KMS-12-BM cells. Because KMS-12-PE was cultivated 2 months before KMS-12-BM, these differences might be related to their origin (pleural effusion and bone marrow) or the phases of disease progression. However, these biological differences may help clarify myeloma cell biology and lead to improvement in treatment for myeloma patients.

Impact of chemotherapy on the mobilisation, harvest and economic costs of autologous peripheral stem cell transplantation in patients with multiple myeloma.
    Leukemia & lymphoma, 2000, Volume: 37, Issue:5-6

    To evaluate factors affecting mobilisation and harvest and to calculate the economic costs of autologous stem cell transplantation in multiple myeloma (MM) we analysed 29 consecutive patients who had been transplanted at the Nijmegen University Hospital between January 1992 and February 1999. Thirteen patients had been treated with three or more melphalan cycles before transplantation (melphalan group), while four of the remaining 16 patients (no-melphalan group) had only received one melphalan cycle with an interval of one year or longer before harvest. The two groups were analysed for differences in mobilisation, harvest and the costs. Collection of a sufficient number of peripheral stem cells failed in 4 patients in the melphalan group, and these patients were transplanted with both bone marrow and peripheral stem cells. The greater need for growth factors (median 6,400 microg vs 4,500 microg) and the longer duration of admission (median 8 days vs 3 days) for mobilisation in the melphalan group increased significantly (p=0.01) the total mobilisation costs (median fl 13,876 vs fl 6,101). The greater number of apheresis sessions (median three) and the additional bone marrow harvests for patients who could not achieve a sufficient number of stem cells, increased significantly (p<0.001) the total harvest costs (median fl 9,690 vs fl 1,615) in the melphalan group. This resulted in significantly (p=0.008) higher overall costs of the procedure (median: fl 49,576 vs fl 35,889). The haematopoietic recovery of all groups was similar. The no-melphalan group was subdivided in two groups based on the median number of chemotherapy cycles before harvest. The heavily treated group had received more than 5 chemotherapy cycles and the moderately treated group four cycles or less. The median overall costs of these two groups were comparable (median fl 36,837 vs fl 34,351). This study suggests that the administration of stem cell toxic melphalan before harvest contributes to administration of more dosages of growth factor, longer admission duration for mobilisation and higher number of leukaphereses in order to collect sufficient number of stem cells. This resulted in significantly higher overall costs. More cycles of chemotherapy without melphalan did not increase significantly any studied parameter nor the total costs of procedure. Melphalan therapy or heavy pre-treatment did not prolong the repopulation interval, probably due to the infusion of similar number of progen

Heterogeneity in therapeutic response of genetically altered myeloma cell lines to interleukin 6, dexamethasone, doxorubicin, and melphalan.
    Blood, 2000, Nov-01, Volume: 96, Issue:9

    Because there is no known genetic abnormality common to all patients with myeloma, it is important to understand how genetic heterogeneity may lead to differences in signal transduction, cell cycle, and response to therapy. Model cell lines have been used to study the effect that mutations in p53 and ras can have on growth properties and responses of myeloma cells. The U266 cell line has a single mutant p53 allele. Stable expression of wild-type (wt) p53 in U266 cells results in a significant suppression of interleukin (IL)-6 gene expression and in the concomitant suppression of cell growth that could be restored by the addition of exogenous IL-6. Expression of wt p53 also leads to cell cycle arrest and protection from doxorubicin (Dox)- and melphalan (Mel)-induced apoptosis. The addition of IL-6 resulted in cell cycle progression and blocked p53-mediated protection from apoptosis. ANBL6 is an IL-6-dependent cell line that is sensitive to dexamethasone (Dex), Dox, and Mel. IL-6 is able to protect ANBL6 cells from Dex- and Mel- but not Dox-induced apoptosis. To study the effect of an activating mutation in ras, the ANBL6 cell line transfected with either a constitutively activated N- or K-ras gene was used. Both N-ras12 and K-ras12 genes were able to protect ANBL6 cells from apoptosis induced by Dex, Dox, and Mel. These data show that changes in ras or p53 can alter the myeloma cell response to IL-6 and demonstrate that the genetic background can alter therapeutic responses.

Non-myeloablative allogeneic transplantation ('microallograft') for refractory myeloma after two preceding autografts: feasibility and efficacy in a patient with active aspergillosis.
    Bone marrow transplantation, 2000, Volume: 26, Issue:11

    A 59-year-old man with a 4-year history of light chain myeloma relapsing after two preceding autografts and salvage therapy with thalidomide underwent a peripheral blood stem cell (PBSC) transplant from his HLA-identical sister after conditioning with 100 mg/m2 melphalan. Graft-versus-host disease (GVHD) prophylaxis comprised cyclosporine. Despite pulmonary infiltrates and sinusitis at the time of the allograft, it was decided to proceed with the transplant because the myeloma was refractory and rapidly progressive. Sputum cultures obtained 2 days before the allograft grew Aspergillus fumigatus 2 days post transplant. A fumigatus grew repeatedly on specimens obtained post transplant. Prompt hematologic recovery was seen with full donor-type chimerism. The fungal infection subsided gradually on a combination of amphotericin B lipid complex and itraconazole. A second aliquot of donor PBSC was infused electively on day +42 to induce graft-versus-myeloma. Complete remission of the myeloma was achieved by 75 days post transplant. No acute GVHD was seen. No chronic GVHD was seen at 16 weeks when he received the third PBSC infusion. He is currently alive and well in remission 9 months post transplant. This case demonstrates the safety and potential usefulness of allogeneic PBSC transplantation with reduced-intensity conditioning in patients with markedly compromised performance status.

The phenotypic profile of CD34-positive peripheral blood stem cells in different mobilization regimens.
    British journal of haematology, 2000, Volume: 111, Issue:4

    The type of regimen used might result in mobilization of phenotypically and functionally different CD34(+) cells. We compared the phenotype of CD34(+) cells in leukapheresis products of three homogeneous groups: I, healthy individuals treated with granulocyte colony-stimulating factor (G-CSF) alone (n = 13); II, patients mobilized with G-CSF following chemotherapy (n = 16); and III, patients mobilized with G-CSF after high-dose chemotherapeutic pretreatment (n = 24). Multiparameter flow cytometry was performed for CD34(+) subpopulation analysis and focused on adhesion molecules, differentiation markers and megakaryocytic markers relevant for stem cell homing, with special reference to the importance of L-selectin expression. Regimens I and II led to higher numbers of mobilized CD34(+) cells (mean 468 x 10(6) and 491 x 10(6) CD34(+) cells per leukapheresis procedure respectively) than regimen III (mean 41 x 10(6) CD34(+) cells per leukapheresis procedure). Both the expression of L-selectin and CD54 on CD34(+) cells was significantly lower in group III, as was the percentage of megakaryocytic (CD41(+)) progenitors. A higher percentage of primitive (CD38(-) and/or HLA(-)DR(-)) CD34(+) cells was found in group III, correlating with a higher clonogenicity of the CD34(+) cells. However, when comparing the CD34(+)_ subpopulations that were also positive for L-selectin, there was no significant difference between the three regimens. A similar approach for the megakaryocytic CD34+ population resulted in an even worse quality of regimen III: 5.1% of CD34(+) being CD41(+)/L-selectin(+) compared with 9.2% and 8.9% in regimens I and II respectively. We concluded that the phenotypes of the CD34(+) cells in the G-CSF (group I) and G-CSF-chemotherapy (group II) regimens are similar, whereas the phenotype of the CD34(+) cells mobilized in the high-dose regimen (group III) displayed features that might negatively influence homing of the cells. Future studies will be directed towards regimens that will lead to the mobilization of a higher amount of CD34(+) cells with a phenotypically favourable phenotype.

    La Tunisie medicale, 2000, Volume: 78, Issue:10

    Alkylating agents administered with predisone have been the standard therapy for myeloma over the lost three decades. Intensive treatment with autologous hematopoietic support has become the treatment of choice for multiple myeloma patients up to 60 years of age. From march 1999 to january 2000, seven patients with multiple myeloma (stage III) with a median age of 43 years (34-56) received an autologous stem cell transplantation. The myeloablative treatment regimen consisted of high-dose melphalan. All patients had sustained engraftment. The median duration of neutropenia (< 500/mm3) was 12 days (11-140) and the median duration of thrombocytopenia (< 20,000/mm3) was 13 days (11-110). One patient had a complete remission, one a very good partial remission, and 5 patients had a partial remission. With a median follow-up of 8 months (2-12), all patients are alive, without relapse.

Are myeloma patients with renal failure candidates for autologous stem cell transplantation?
    The hematology journal : the official journal of the European Haematology Association, 2000, Volume: 1, Issue:1

    Renal function is one of the most important prognostic factors in multiple myeloma (MM). Patients with renal failure are generally excluded from high dose therapy even though they display a poor prognosis with conventional chemotherapy schemes. The aim of this study was to analyze the outcome of MM patients with renal insufficiency undergoing autologous stem cell transplantation (ASCT), including the evaluation of the quality of PB stem cell collections, kinetics of engraftment, transplant-related mortality, response to high dose chemotherapy and survival.. From a total of 566 valuable patients included in the MM Spanish ASCT registry, three groups of patients were defined: group BA, patients with abnormal renal function at diagnosis but normal at transplant (73 cases); group BB, patients with abnormal function both at diagnosis and at transplant (14 cases); and group AA (control group, 479 cases), patients who constantly had normal renal function.. Patients from groups BA and BB presented with a significantly higher number of adverse prognostic factors, reflecting that we were dealing with high tumor MM cases, as compared with patients from group AA. The number of mononuclear cells, CD34+ cells and CFU-GM cells collected in patients with non-reversible renal insufficiency was similar to those harvested in MM patients with normal renal function. Moreover, neutrophil and platelet engraftments were identical in patients with and without renal failure (days +11 and +12, respectively). By contrast, transplant-related mortality (TRM) was significantly higher in group BB patients (29%) than in groups BA (4.1%) and AA (3.3%). In multivariate analysis only three variables showed independent influence on TRM: poor performance status (ECOG 3), hemoglobin <9.5 g/dl and serum creatinine > or =5 mg/dl. The response to high dose therapy was independent of renal function. Interestingly, 43% of patients from group BB showed an improvement in renal function (creatinine < 2 mg/dl) after transplant. The three-year overall survival from transplantation was 56, 49 and 61% for the BB, BA and AA groups, respectively, with a statistically significant difference favoring group AA (P<0.01). PFS did not differ significantly between the three groups of patients. In multivariate analysis the only unfavorable independent prognostic factors for overall survival were poor performance status either at diagnosis or at transplant, high beta(2)-microglobulin levels, and no response to transplant. According to these results, ASCT is an attractive alternative for MM patients with renal insufficiency, and it should not constitute a criterion for exclusion from transplant unless patients display poor performance status and very high creatinine levels (>5 mg/dl).

Primary plasma cell leukemia: clinical, immunophenotypic, DNA ploidy, and cytogenetic characteristics.
    Blood, 1999, Feb-01, Volume: 93, Issue:3

    We report on a series of 26 patients diagnosed with primary (de novo) plasma cell (PC) leukemia (PCL) in whom we analyzed the clinicobiologic characteristics of the disease together with the immunophenotype, DNA cell content, proliferative index, and numeric chromosomal aberrations of the neoplastic PC, and compared them with 664 multiple myeloma (MM) patients at diagnosis. The median age, sex ratio, and bone lesion extension were similar, but PCL cases displayed a higher prevalence of clinical stage III, extramedullary involvement, and Bence Jones cases, with fewer IgA cases than for MM patients. In addition, according to several prognostic indicators (beta2-microglobulin serum level, proportion of S-phase PCs, proteinuria, calcium serum level, lactate dehydrogenase [LDH] and renal function), the incidence of adverse prognostic factors was significantly higher in PCL versus MM. Immunophenotypic expression was similar for CD38, CD138, CD2, CD3, CD16, CD10, CD13, and CD15, but PCL differed from MM in the expression of CD56, CD9 HLA-DR, CD117, and CD20 antigens. Twenty-two PCL cases were diploid and one was hypodiploid, while most MM cases (57%) showed DNA hyperdiploidy. With the fluorescent in situ hydridization (FISH) technique, 12 of 13 PCL cases displayed the numeric aberrations, -13 (86%), +/-1 (57%), +18 (43%), and -X in women (25%), but they lacked several numeric aberrations usually found in MM such as +3, +6, +9, +11, and +15. PCL cases had a lower overall response to therapy than MM cases (38% v 63%, P =.01332). Among PCL patients, a trend for a worse response was observed in cases treated with melphalan and prednisone (MP) versus polychemotherapy. Overall survival was significantly worse in PCL versus MM patients (8 v 36 months, P <.0001), but it was significantly better in PCL patients treated with polychemotherapy versus MP (18 v 3 months, P =.0137). By contrast, MM patients did not show significant differences in overall survival according to the treatment used, MP or polychemotherapy. Ten variables seemed to predict survival in PCL patients, but only the beta2-microglobulin level and S-phase PCs retained an independent value in multivariate analysis. In summary, our study illustrates that PCs from PCL display singular phenotypic, DNA cell content, and cytogenetic characteristics that lead to a different disease evolution versus MM.

Cell adhesion mediated drug resistance (CAM-DR): role of integrins and resistance to apoptosis in human myeloma cell lines.
    Blood, 1999, Mar-01, Volume: 93, Issue:5

    Integrin-mediated adhesion influences cell survival and may prevent programmed cell death. Little is known about how drug-sensitive tumor cell lines survive initial exposures to cytotoxic drugs and eventually select for drug-resistant populations. Factors that allow for cell survival following acute cytotoxic drug exposure may differ from drug resistance mechanisms selected for by chronic drug exposure. We show here that drug-sensitive 8226 human myeloma cells, demonstrated to express both VLA-4 (alpha4beta1) and VLA-5 (alpha5beta1) integrin fibronectin (FN) receptors, are relatively resistant to the apoptotic effects of doxorubicin and melphalan when pre-adhered to FN and compared with cells grown in suspension. This cell adhesion mediated drug resistance, or CAM-DR, was not due to reduced drug accumulation or upregulation of anti-apoptotic Bcl-2 family members. As determined by flow cytometry, myeloma cell lines selected for drug resistance, with either doxorubicin or melphalan, overexpress VLA-4. Functional assays revealed a significant increase in alpha4-mediated cell adhesion in both drug-resistant variants compared with the drug-sensitive parent line. When removed from selection pressure, drug-resistant cell lines reverted to a drug sensitive and alpha4-low phenotype. Whether VLA-4-mediated FN adhesion offers a survival advantage over VLA-5-mediated adhesion remains to be determined. In conclusion, we have demonstrated that FN-mediated adhesion confers a survival advantage for myeloma cells acutely exposed to cytotoxic drugs by inhibiting drug-induced apoptosis. This finding may explain how some cells survive initial drug exposure and eventually express classical mechanisms of drug resistance such as MDR1 overexpression.

Response level and survival after conventional chemotherapy for multiple myeloma: a Finnish Leukaemia Group study.
    European journal of haematology, 1999, Volume: 62, Issue:2

    The relation between overall survival time (OS) and response level (CR, 75%R, PR, MR, SD) was analysed in 432 multiple myeloma patients from 4 prospective Finnish Leukaemia group trials, treated with conventional chemotherapy. The primary regimen was either melphalan and prednisolone or combination chemotherapy with melphalan as a main component. Both the influence of the pre-treatment factors in patients with different levels of responses and the aspects related to chemotherapy were analysed. The 324 patients aged up to 70 yr and the 10(8) older patients were dealt with as separate groups. Irrespective of the primary chemotherapy regimen, the level of response was not significantly influencing in the OS time, and this was true in both age categories. The median OS of the patients up to 70 yr of age who had any response was 57 months, compared to the 10 months of those with PD (p < 0.001). The corresponding figures for the older patients were 40 and 4 months (p <0.001), respectively. The pretreatment prognosticators for the patients with minimal responses were not more favourable than for patients with responses at higher levels. The prolonged primary chemotherapy was favourable in patients having responses less than PR. Accordingly, the primary goal of conventional chemotherapy for multiple myeloma is stabilization of disease, not the level of response.

Early harvest and late transplantation as an effective therapeutic strategy in multiple myeloma.
    Bone marrow transplantation, 1999, Volume: 23, Issue:3

    Transplantation after high-dose chemotherapy prolongs survival in patients with multiple myeloma compared with standard therapy. It is unclear whether the optimal timing of transplantation is immediately after induction chemotherapy or whether stem cells may be cryopreserved for transplantation at subsequent progression or relapse. In this study, stem cells were collected within 6 months of diagnosis, followed by transplantation only at progression of myeloma. One hundred and eighteen patients with multiple myeloma had stem cells collected and cryopreserved. Eleven had transplants early in the disease after they demonstrated failure to respond to primary therapy. The remaining 107 were eligible for transplants when there was evidence of progressive disease. Of the 118 patients, 67 had transplants, nine died of progressive disease before transplantation, and 42 remain alive in plateau phase. The median survival of the group is 58.5 months; 67 are alive. Serum beta2-microglobulin, bone marrow labeling index (S phase), and hemoglobin level predicted overall survival (P < 0.006, P < 0.001, and P < 0.01, respectively). We conclude that early cryopreservation of blood stem cells followed by transplantation at progression is a feasible approach to therapy in patients with myeloma. The underlying biology of the disease has a greater impact on survival than the timing of transplantation. A prospective randomized trial is required to answer definitively the question of the optimal timing of blood cell transplantation.

Mandibular mass as the presenting manifestation of IgM myeloma in a 22-year-old man.
    Annals of hematology, 1999, Volume: 78, Issue:2

    We report here the youngest known IgM myeloma patient to have presented with a mandibular mass. A 22-year-old Chinese man sought medical attention due to a mass over his right mandible that had been growing progressively for 6 months. A solitary osteolytic lesion in the right mandible was identified radiologically. Incisional biopsy revealed the presence of plasma cells of monoclonal origin, as evidenced by the exclusively positive staining of the kappa light chain. The diagnosis of multiple myeloma with mandibular involvement was confirmed by bone marrow examination. Further tests, including immunoglobulin electrophoresis and assay of the serum levels of kappa and lambda light chains, demonstrated that his myeloma was of the IgM, kappa subtype. The patient achieved a nonsustained partial response to six courses of melphalan and prednisolone therapy and palliative radiotherapy.

Evaluation of minimal residual disease by interphase FISH in multiple myeloma: does complete remission exist?
    Leukemia, 1999, Volume: 13, Issue:4

    As in other hematological malignancies, the achievement of a complete remission (CR) is important in multiple myeloma but is still based on common cytological and electrophoretic criteria. In this report, we studied 14 patients who achieved an apparent CR following high-dose therapy using fluorescence in situ hybridization (FISH) analysis. Although the results were difficult to interpret in two patients, 12 of 14 patients had unequivocal persistence of abnormal plasma cells in their bone marrow. Our results suggest that only a few patients, if any, are in true CR following one course of high-dose therapy and are in favor of post-transplantation treatments.

Establishment and characterization of a CD95 (Fas/Apo-1)-negative myeloma cell line.
    Acta haematologica, 1999, Volume: 101, Issue:3

    Although expression of CD95 (Fas/Apo-1) on myeloma cells has been reported, its significance is not clearly understood. We established a myeloma cell line, KHM-11ad (11ad), from a parental cell line, KHM-11, by collecting cells adhered to a plastic dish. KHM-11 cells have been reported to be positive for CD45 and CD95 (Fas/Apo1), and negative for a myelomonocytic antigen, CD13. Interestingly, CD95 was not detected in 11ad. Expression of CD45 was also significantly decreased in 11ad cells while expression of CD13 was detected in these cells. The growth rate of 11ad cells was 1.7 times lower than that of KHM-11 cells. Analysis of adhesion molecules showed that expression of VLA4 and CD44 was significantly suppressed in 11ad. The IC50 of melphalan (L-PAM) for 11ad cells was 50 times higher than that for KHM-11, indicating that 11ad is significantly refractory to L-PAM than KHM-11 cells. Induction of apoptosis by doxorubicin and cycloheximide was suppressed in 11ad cells compared with those in KHM-11 cells. Western blot analysis for Bcl-2 family of proteins showed that Bax was expressed at a 2.2 times lower level in 11ad cells than in KHM-11 cells while there was no difference in expression of Bcl-2, Bcl-Xs nor Bcl-XL. These results suggest that CD95-negative myeloma cells may have characteristics as follows: (1) slow proliferation; (2) low sensitivity to apoptosis; (3) low expression of VLA4, CD44 and Bax. Although these intraclonal variations were based on the findings of cell lines, these may reflect similar variations in vivo. The 11ad line may be a suitable model for analyzing intraclonal variation of myeloma cells.

Posttreatment M-protein nadir level is a significant prognostic factor associated with survival in multiple myeloma. Nagoya Myeloma Cooperative Study Group.
    Japanese journal of cancer research : Gann, 1999, Volume: 90, Issue:3

    In the present study 142 patients with myeloma (102 with IgG M-protein and 40 with IgA) treated with either VMCP (65 patients) or MMCP (77 patients) as remission induction therapy were retrospectively analyzed. Response to treatment was evaluated in terms of a more-than-50% fall of pretreatment M-protein and the posttreatment M-protein nadir. Though significantly more patients treated with MMCP achieved partial response (PR) as compared with those treated with VMCP (P=0.019) and though patients achieving PR showed a significantly longer survival than those with less responsiveness (P=0.0091), the difference in survival curves between the two treatment groups was not significant (P=0.1871). The difference in response between the treatment groups evaluated in terms of posttreatment nadir was not significant (P=0.507). Multivariate analysis identified posttreatment M-protein nadir as a significant prognostic factor associated with survival, along with 3 other factors: sex, performance status, and hemoglobin. The lack of difference between the survival curves for patients treated with the 2 regimens despite the significantly different response rates evaluated in terms of percent fall of pretreatment M-protein levels was considered to be due to the lack of a difference in the ability to induce a deep posttreatment nadir between the regimens. Posttreatment M-protein nadir is an important prognostic factor associated with survival and should be included in the evaluation of the efficacy of chemotherapy.

Melphalan 220 mg/m2 followed by peripheral blood stem cell transplantation in 27 patients with advanced multiple myeloma.
    Bone marrow transplantation, 1999, Volume: 23, Issue:10

    Twenty-seven patients with advanced multiple myeloma received high-dose therapy with 220 mg/m2 i.v. melphalan (HDM220) followed by autologous stem cell transplantation. At the time of HDM220, nine patients had primary refractory disease and 18 were in relapse after having responded to prior high-dose therapy. No toxic deaths were observed. The major adverse side-effect was grade 4 mucositis in 63% of patients. Two patients experienced reversible paroxysmal atrial fibrillation after HDM220. For the whole group of patients, the actuarial 3-year overall survival (OS) and event-free survival (EFS) are 36.1 and 16.9%, respectively. The probability of OS and EFS was significantly lower in patients treated for refractory relapse (22.9 and 0% at 2 years, respectively) as compared to primary refractory patients (66.7 and 64.3% at 2 years, respectively) or patients treated for chemosensitive relapse (42.9% at 2 years) (P = 0.0001). Low beta2-microglobulin and CRP levels at the time of HDM220 were associated with a better OS and EFS. Our data suggest that HDM220 followed by ASCT should be considered in patients with primary refractory disease or chemosensitive disease relapsing after prior intensive therapy.

Collection of peripheral blood stem cells after a preceding autograft: unfavorable effect of prior interferon-alpha therapy.
    Bone marrow transplantation, 1999, Volume: 24, Issue:1

    Eighty-eight previously autografted (78 transplanted twice and 10 once) myeloma patients who had no cryopreserved stem cells available for possible future use received G-CSF for mobilization of stem cells. One-fourth of the patients had progressive disease at the time of apheresis. All patients had received 200 mg/m2 melphalan for the first transplant. The interval between the preceding transplant and the harvest was 5-68 months (median 29). A total of 0.46-9.16 (median 3.03) x 10(6) CD34+ cells/kg were collected. More than 2 x 10(6)/kg CD34+ cells were collected in 76% of the patients, and > or = 5 x 10(6)/kg in 14%. On multivariate analysis, patients with platelet counts of > or = 200 x 10(9)/l (P < 0.0001), those who had not received any myelosuppressive chemotherapy between the last transplant and the collection (P = 0.02), and those who had received interferon-alpha for < or = 6 months (P = 0.03) had better collections. Eleven of 12 patients autografted with these cells had prompt neutrophil recovery (median 10 days to 0.5 x 10(9)/l) but recovery to 50 x 10(9)/l platelets was delayed or incomplete in 11 of 12. We conclude that it is possible to harvest peripheral blood stem cells with G-CSF stimulation in patients who have been autografted previously. Limited data suggest that platelet recovery may be suboptimal when these cells are used. These findings have practical implications for patients with malignant diseases in remission after autografting who may be candidates for future salvage therapy but have no stem cells stored, and for patients with chronic myeloid leukemia who are on long-term interferon-alpha therapy to attain cytogenetic remission for eventual collection of normal stem cells.

The patient was treated with melphalan and prednisone for 1 year. After that, he was administered interferon-alpha2b (IFN-alpha2b; 3 MU, 3 times a week) as maintenance therapy for 2 years. At present, 5 years and 6 months after the initial diagnosis, the patient receives IFN-alpha2b (3 MU, twice a week) and remains in complete haematological remission.

Deletion 5q31 in patients with stable, melphalan-treated multiple myeloma.
    Cancer genetics and cytogenetics, 1999, Volume: 113, Issue:1

    The risk of myelodysplastic syndrome (MDS) or acute myeloblastic leukemia (AML) in patients with multiple myeloma has been estimated to be 10-20% after 10 years. Most myeloma patients develop MDS/AML after 3-4 years of treatment with alkylating agents, mainly melphalan; chromosomes 5 and 7 are most frequently involved. We studied 14 patients with myeloma by fluorescence in situ hybridization (FISH) with a probe to 5q31 (the critical area of deletion on chromosome 5) to verify whether deletion of 5q31 occurs during the course of stable, uncomplicated myeloma, and to assess the clinical importance of this abnormality. We found 2 patients (14%) with deletion of 5q31 in 30-40% of their peripheral white blood cells. One patient with this deletion received a high cumulative amount of melphalan, and the other patient was treated with multiple alkylating agents, including melphalan. In these patients, no clinical or laboratory evidence of transformation occurred 14 and 12 months after the finding of the aberration. These findings suggest that 5q-may occur months prior to the overt development of (t)-MDS/AML, and raise important concerns regarding the management of patients with this and similar aberrations, including modification of treatment and performance of cytogenetic evaluation prior to autologous or PSC transplantation. The clinical and biological implications of these findings should be evaluated in larger clinical and laboratory studies.

The relationship between monoclonal myeloma precursor B cells in the peripheral blood stem cell harvests and the clinical response of multiple myeloma patients.
    British journal of haematology, 1999, Volume: 106, Issue:3

    The aim of this study was to determine the presence of monoclonal myeloma precursor B cells in peripheral blood stem cell harvests and to investigate their role in the clinical outcome of multiple myeloma patients. A total of 39 multiple myeloma patients were treated with a sequential therapy including double high-dose melphalan therapy followed by a double transplant procedure. The apheresis products for the second transplant were purged using a panel of four or five different mouse monoclonal antibodies against B-cell antigens (CD10, CD19, CD20, CD22 and CD37). In 19/39 patients a tumour-specific CDR III signal was identified in the diagnostic bone marrow. Gene scan analysis after CDR III PCR of the magnetic bead isolated B-cell fraction from the apheresis products in these 19 patients revealed three different patterns: 32% of patients had a predominantly monoclonal B-cell population; 63% of patients had an identifiable monoclonal signal within an oligoclonal B-cell population. In only 1/19 patients were no monoclonal B cells identified in the B-cell population of the apheresis product. A correlation between the clonal pattern and the clinical response after sequential chemotherapy was found. Patients with a predominance of monoclonal myeloma or myeloma precursor B cells had an early relapse or achieved a minimal response or a partial remission. Patients with an oligo- and/or polyclonal pattern achieved a high percentage of partial as well as complete remissions.

The replacement therapy consisted of hemodialysis, hemofiltration, hemodiafiltration. All the patients received full-dose polychemotherapy according to the programs M-2 and VAD.. 69% of the patients retained normal renal function. 23% of the patients died. Partial recovery of renal function was observed in 1 patient who had to undergo dialysis once in 10-12 days. The patients survived from 5 days to 36 months (mean 20.6 months). The main causes of death in renal failure were sepsis (38%) and hemorrhagic stroke (14%).

This may change the clinical practice of haematopoietic cell transplantation and high-dose chemotherapy because the morbidity and hospitalisation associated with neutropenia could be avoided or reduced.

    We report a case of IgA-kappa multiple myeloma in a 68-year-old woman that was revealed by concomitant pleural and pericardial effusion. These effusions were found to be caused by myeloma and were verified by cytological examination of the pleural fluid and pericardial biopsy. The patient had neither osteolytic lesions nor Bence-Jones proteinuria. After a pericardiocentesis, her condition improved with a melphalan and prednisolone treatment. As far as we know, such a phenomenon is rare and has never been reported yet as a way of diagnosing multiple myeloma.

Encephalopathy complicating high-dose melphalan.
    Bone marrow transplantation, 1999, Volume: 24, Issue:10

    High-dose melphalan (HDM) with peripheral blood stem cell transplant (PBSCT) is a common treatment for patients with multiple myeloma (MM) and more recently also with AL amyloidosis (ALA). We report two female patients with severe renal failure who underwent treatment with HDM for MM (patient 1) and ALA (patient 2). Both patients developed severe encephalopathy with generalised tonic-clonic seizures and a Glasgow Coma Scale (GCS) of 3/15. Causes for coma such as infections, metabolic disturbances, cerebral ischaemia or haemorrhage were excluded. Patient 1 died on day 25 post transplant while comatose. Patient 2 recovered from her comatose state 18 days after transplantation. To our knowledge this is the first report on a possible role of high-dose melphalan in the development of encephalopathy.

Acute promyelocytic leukaemia complicating multiple myeloma: evidence of different cell lineages.
    Leukemia & lymphoma, 1999, Volume: 35, Issue:5-6

    The association of leukemia and multiple myeloma is well described usually as a complication of chemotherapy but also in the absence of chemotherapy or at diagnosis. Such leukemias are typically acute myeloid leukemia (AML), particularly myelomonocytic subtype, and cases of acute promyelocytic leuke (APL) are rarely reported. Controversy exists as to whether myeloma and AML originate from a single haematopoietic progenitor or arise from different cell lineages. We report a case of a 58 year old female who developed APL 10 months following diagnosis of nonsecretory light chain (kappa) myeloma which had been treated with local spinal irradiation and low dose oral melphalan and prednisone. Clonality had originally been demonstrated by light chain restriction (kappa) of her bone marrow plasma cells whilst immunoglobulin heavy chain and T cell receptor genes were germ line. At development of APL cytogenetics revealed t(15;17) and PML-RAR fusion gene was detected by RT-PCR. The patient was treated with all-trans retinoic acid (ATRA) and received 2 cycles of consolidation chemotherapy with Idarubicin. Following this therapy the t(15;17) and PML-RAR were both undetectable whilst the clonal population of kappa staining plasma cells persisted. This particular patient represents a rare case of APL complicating multiple myeloma with persistence of the myeloma clone but disappearance of PML-RAR alpha RNA following therapy. This case study appears to support the argument that the APL and myeloma originated from distinct cell lineages.

Reduced bone marrow stem cell pool and progenitor mobilisation in multiple myeloma after melphalan treatment.
    Medical oncology (Northwood, London, England), 1999, Volume: 16, Issue:4

    The content of stem cells was analysed in bone marrow samples from 75 multiple myeloma patients. In unstimulated bone marrow the percentage of CD34+ cells was significantly reduced in 11 patients previously treated with melphalan-prednisolone (MP)(median= 0.15%) compared to median 0.87% in 31 untreated patients (P=0.0001). The bone marrow cellularity in the two groups did not differ. There was no correlation between the number of courses or total dose of melphalan and content of CD34+ cells in the bone marrow. The clonogenicity as well as the ability to expand the marrow stem cell pool during growth factor treatment were also reduced in MP treated patients compared to untreated patients. Analysis of different subsets of CD34+ cells revealed no influence on the pre B cell compartment in the bone marrow by MP treatment, but the committed stem cells (CD34+CD38+) were reduced more than the uncommitted stem cells (CD34+CD38-) in the MP treated group compared to the untreated patients. Mobilisation to and harvest of total number of CD34+ cells from peripheral blood was also reduced in the MP treated group. There was, however, no difference in the distribution between CD34+CD38+ and CD34+CD38- populations in the leukapheresis products in the untreated and the melphalan-treated group, suggesting selective mobilisation of CD34+CD38+ cells and/or differentiation of CD34+CD38-cells during growth factor stimulation. We conclude that melphalan decreased the number of stem cells in the bone marrow, the ability to expand the stem cell pool and mobilise stem cells to the pheripheral blood.

Leukoencephalopathy in multiple myeloma: two case reports.
    Annals of oncology : official journal of the European Society for Medical Oncology, 1999, Volume: 10, Issue:12

    No case of leukoencephalopathy has been reported associated with multiple myeloma.. We report on two patients with a very rare association of leukoencephalopathy and multiple myeloma revealed by cognitive impairment.. Chemotherapy has improved neurological and biological signs. Radiological abnormalities have been stabilized.. The authors suggest that leukoencephalopathy is probably a direct cerebral expression of malignant gammopathy.

[Malignant lymphoma with c-myc gene rearrangement in a patient receiving long-term treatment for multiple myeloma].
    [Rinsho ketsueki] The Japanese journal of clinical hematology, 1999, Volume: 40, Issue:12

    We encountered a 65-year-old woman with diffuse large B-cell lymphoma showing t(8;14)(q24;q32) and c-myc gene rearrangement that developed following 12 years of melphalan-based chemotherapy for multiple myeloma. Short-term remission was obtained by CHOP chemotherapy. However, shortly thereafter the patient died of an aggressive progression of lymphoma. It was suspected that the lymphoma was a secondary malignancy related to the treatment with cytotoxic agents and radiation for prolonged multiple myeloma. The chromosomal abnormality t(8;14)(q24;q32) is rare in secondary malignancies. Overexpression of c-myc by gene rearrangement may be associated with clinical courses manifested by the rapid progression of lymphoma.

Peripheral blood progenitor cell transplantation in multiple myeloma following high-dose melphalan-based therapy.
    Recent results in cancer research. Fortschritte der Krebsforschung. Progres dans les recherches sur le cancer, 1998, Volume: 144

    The objective of our study was to evaluate the efficacy and toxicity of a high-dose melphalan-based therapy with or without total body irradiation (TBI) followed by peripheral blood progenitor cell (PBPC) transplantation in patients with multiple myeloma. Between June 1992 and June 1996, 104 patients (71 male, 33 female) with a median age of 51 years (range 30-65 years) underwent transplantation at our center. PBPC were mobilized using high-dose chemotherapy followed by treatment with G-CSF. Fifty patients were treated with TBI+melphalan 140 mg/m2 while 54 patients received melphalan 200 mg/m2. Following PBPC autografting, the median time to attainment of platelets > or = 20 x 10(9)/l and neutrophils > or = 0.5 x 10(9)/l was 11 and 14 days, with no difference between the treatment groups. In the TBI group significantly longer periods of total parenteral nutrition were required due to the occurrence of severe mucositis. Two patients from the TBI group died of transplantation-related complications. Following high-dose treatment, remission state improved in 43 out of 102 patients. No statistically significant advantage in reaching complete or partial remission was observed with TBI+high-dose melphalan compared to the treatment with high-dose melphalan alone. The optimal high-dose treatment, with particular reference to the inclusion or omission of TBI, should be prospectively investigated.

Elevated serum concentrations of hepatocyte growth factor in patients with multiple myeloma. The Nordic Myeloma Study Group.
    Blood, 1998, Feb-01, Volume: 91, Issue:3

    Serum from 398 myeloma patients at diagnosis and serial samples from 29 patients were analysed for hepatocyte growth factor (HGF). HGF was elevated at diagnosis in 43% of myeloma patients compared with healthy controls (median 1.00 ng/mL and 0.44 ng/mL, respectively; P < .00001). In the group with elevated HGF levels 46% of the patients reached plateau phase, as compared with 60% of the patients with low HGF levels (P = .005), and the median survival time was 21 and 32 months, respectively (P = .002). In a univariate Cox regression analysis, HGF was a significant predictor of mortality (P = .02). In the subgroup of patients with beta 2-microglobulin levels less than or equal to 6 mg/L, high versus low HGF was a prognostic factor when a multivariate Cox regression analysis was performed. In serial samples HGF was higher at the time of diagnosis and relapse (median 0.57 ng/mL and 0.52 ng/mL, respectively; P = .0018) than at response (median 0.24 ng/mL, P = .008). We conclude that HGF may be a useful follow-up parameter in myeloma patients. Measurement of HGF may identify a group of patients with poor response to melphalan-prednisone treatment and short survival. HGF was a prognostic factor in patients with high levels of beta 2-microglobulin.

Lung-resistance-related protein expression is a negative predictive factor for response to conventional low but not to intensified dose alkylating chemotherapy in multiple myeloma.
    Blood, 1998, Feb-01, Volume: 91, Issue:3

    This study was undertaken to assess the significance of lung-resistance related protein (LRP) expression in plasma cells from untreated multiple myeloma (MM) patients and to determine whether LRP was associated with a poor response and survival in patients treated with different dose regimens of melphalan. Seventy untreated patients received conventional oral dose melphalan (0.25 mg/kg, day 1 to 4) combined with prednisone (MP) or intravenous intermediate-IDM; 70 mg/m2) or high- (140 mg/m2) dose Melphalan (HDM). LRP expression was assessed with immunocytochemistry using the LRP-56 monoclonal antibody. LRP expression was found in 47% of patients. In the MP treated patients, LRP expression was a significant prognostic factor regarding response induction (P < .05), event free survival (P < .003), and overall survival (P < .001). In the intensified dose melphalan treated patients LRP did not have a prognostic value. The response rates of LRP-positive patients to MP and IDM/HDM were 18% versus 81%, respectively (P < .0001). We conclude that LRP is frequently expressed in untreated MM patients and is an independent predictor for response and survival in patients treated with MP. Pretreatment assessment of LRP identifies a subpopulation of patients with a poor probability of response to conventional dose melphalan. Dose intensification of melphalan is likely to overcome LRP-mediated resistance.

Primary systemic amyloidosis with delayed progression to multiple myeloma.
    Cancer, 1998, Apr-15, Volume: 82, Issue:8

    Primary systemic amyloidosis (AL) and multiple myeloma both are clonal plasma cell proliferative disorders. Although 10-15% of patients with myeloma have coexisting primary amyloidosis, it is unusual for patients with primary amyloidosis to progress to myeloma at a later date. The authors describe a case series of six patients in whom such progression occurred.. A computerized search was done of the medical records of all patients seen at the Mayo Clinic between January 1, 1960 and December 31, 1994 with a diagnosis of AL. Of 1596 patients with AL, 6 patients (age range, 60-74 years; median age, 68 years) with biopsy-proven AL were reviewed in whom delayed (at least 6 months after the diagnosis of AL) progression to multiple myeloma occurred.. At the time of the diagnosis of AL, none of the six patients had evidence of multiple myeloma. The dominant manifestation of AL was peripheral neuropathy in three patients and cutaneous AL, renal AL, and amyloid arthropathy in one patient each. The diagnosis of multiple myeloma was made 10-81 months after the diagnosis of AL, based on the demonstration of multiple osteolytic lesions (4 patients) or marked bone marrow infiltration (> or = 50%) by plasma cells (5 patients). Two patients had received chemotherapy (melphalan and prednisone) for AL. Five patients received chemotherapy (four patients) or high dose methylprednisolone (one patient) after the diagnosis of multiple myeloma. Five patients died, and the median actuarial survival after the diagnosis of multiple myeloma was 20 months. Multiple myeloma was the cause of death in four patients; one patient died of systemic amyloidosis. In 2 patients death occurred within 3 months.. AL occasionally progresses to overt multiple myeloma. These cases usually occur in patients without significant cardiac or hepatic AL who live long enough to develop multiple myeloma.

Idiotypic protein-pulsed adherent peripheral blood mononuclear cell-derived dendritic cells prime immune system in multiple myeloma.
    Clinical cancer research : an official journal of the American Association for Cancer Research, 1998, Volume: 4, Issue:4

    Adherent peripheral blood mononuclear cell-derived dendritic cells pulsed with autologous idiotypic protein (Id) were given to a patient with advanced-stage refractory myeloma. Potentially beneficial antimyeloma Id-specific immune responses were produced, characterized by MHC-dependent T-cell-proliferative responses with cytokine release and the production of anti-Id antibodies. A T-cell line generated after vaccination was also able to lyse autologous Id-pulsed targets and recognize fresh autologous myeloma cells. The immune responses were associated with a transient minor fall in the serum Id level and were not ablated by high-dose myeloablative chemotherapy. This report therefore demonstrates the clinical use of adherent peripheral blood mononuclear cell-derived dendritic cells for vaccination in cancer and the persistence of immune responses after high-dose chemotherapy. Such a therapeutic approach may be useful in reducing the relapse rate in patients who have minimal residual disease after chemotherapy.

Second attempts at mobilization of peripheral blood stem cells in patients with initial low CD34+ cell yields.
    Journal of hematotherapy, 1998, Volume: 7, Issue:3

    The purpose of this study was to determine the effectiveness of second mobilization strategies in patients who yielded < 2.5 x 10(6) CD34+ PBSC/kg after initial mobilization. Repeat mobilization attempts were made with chemotherapy and G-CSF (n = 61) or G-CSF alone (n = 58) in patients who failed initial mobilization with chemotherapy and G-CSF (n = 92) or G-CSF alone (n = 27). A median of 0.27 x 10(6) CD34+ cells/kg per apheresis was collected after the second mobilization, compared with 0.16 with initial harvests (p = 0.0001). Forty-eight percent achieved a target CD34+ cell dose > or = 2.5 x 10(6)/kg when harvests from the first and second mobilizations were combined. Fifteen of 17 patients (88%) with > or = 1.5 x 10(6) CD34+ cells/kg harvested after first mobilization had > or = 2.5 x 10(6) CD34+ cells/kg collected when first and second harvests were combined, as compared with 42 of 102 (41%) achieving < 1.5 x 10(6) CD34+ cells/kg with first PBSC harvests (p = 0.0001). Second mobilizations with chemotherapy and G-CSF or G-CSF alone resulted in similar CD34+ cell yields. Toxicities of second mobilizations were comparable with those of first mobilizations. Seventy-nine patients (66%) received high-dose chemotherapy with PBSC support, with recovery of neutrophils and platelets in a median of 11 and 15 days, respectively. Transplant-related mortality was 4%, and event-free survival at 2 years was 0.34. It was concluded that second mobilization attempts in patients who fail to achieve > or = 2.5 x 10(6) CD34+ cells/kg on initial mobilization were successful in 48% of patients. G-CSF alone was as effective as chemotherapy plus G-CSF in mobilizing CD34+ cells and was associated with less morbidity.

Multiple myeloma with associated polyneuropathy in a German shepherd dog.
    The Journal of small animal practice, 1998, Volume: 39, Issue:5

    A 12-year-old female, neutered German shepherd dog developed progressive hindlimb followed by forelimb ataxia leading to tetraplegia. Neurological examination suggested lower motor dysfunction. Biochemical evaluation revealed a monoclonal hypergammaglobulinaemia, hypoalbuminaemia and hypercalcaemia. Multiple lytic lesions were identified radiographically in numerous bones. A bone marrow aspirate confirmed the diagnosis of multiple myeloma, with large numbers of plasma cells seen in clusters. An electromyogram revealed positive sharp waves and fibrillation potentials in the skeletal muscles of the limbs, suggesting a polyneuropathy. The dog was treated with chemotherapy using melphalan and prednisolone. Both the hypergammaglobulinaemia and the polyneuropathy resolved and the dog had normal motor function four weeks after commencing treatment. Polyneuropathy may occur as a paraneoplastic syndrome secondary to myeloma, and in this case was reversible following treatment of the underlying disease.

Reduced progression-free survival in elderly patients receiving intensification with autologous peripheral blood stem cell reinfusion for multiple myeloma.
    Bone marrow transplantation, 1998, Volume: 21, Issue:10

    Between 1990 and 1997, 55 patients with high risk multiple myeloma underwent high-dose therapy with peripheral blood stem cell transplantation. Intensification consisted of high-dose L-PAM in 54 patients, and 15 patients underwent a second high-dose treatment. Thirty patients received total body irradiation. Twenty patients were more than 60 years old. Thirty-five patients were intensified during first response. The overall response rate was 78%. There were four toxic deaths. The median overall survivals after intensification and after first treatment of myeloma were greater than 48 months and 71 months, respectively. Conversely freedom from progression after intensification was short, with a median of 22 months. Freedom from progression was significantly shorter in patients older than 60 (12 months), and in patients who had received more than 75 mg/m2 of L-PAM before intensification (16 months). Although intensification is feasible in elderly patients the benefit appears to be reduced in this subgroup of patients. Prior therapy with high cumulative doses of L-PAM should be avoided in patients who will receive high-dose L-PAM for therapeutic intensification.

Bcl-2 overexpression is associated with resistance to dexamethasone, but not melphalan, in multiple myeloma cells.
    International journal of oncology, 1998, Volume: 13, Issue:2

    Multiple myeloma (MM) is an incurable disease despite an initial response-rate of >60% with conventional or high-dose chemotherapy. Glucocorticosteroids such as dexamethasone (DEX) and alkylating agents such as melphalan (MEL) are capable of inducing complete responses (CR) in >50% of MM patients, however, resistance to these drugs develop rapidly, in >90% of patients, within 2 years of treatment. The exact mechanism of resistance to these drugs is not known. We investigated the mechanism of resistance to DEX and MEL. In particular, we investigated the role of bcl-2 in development of resistance to these two drugs. We tested the role of bcl-2 by transfecting 2 low bcl-2-expressing myeloma cell lines, ARP-1 and 8226, with a bcl-2 expression vector and compared the effects of DEX and MEL on apoptosis, cell cycle distribution and the levels of proapoptotic (bax) and antiapoptotic (bcl-2, bclx) proteins. The results indicate that the two drugs act by a different mechanism with respect to all the parameters tested. While DEX-induced apoptosis was dependent on the level of bcl-2 expression, MEL-induced apoptosis was independent of bcl-2 levels. Treatment with DEX of the low bcl-2-expressing cells (DEX-sensitive) resulted in a rapid apoptosis from all phases of the cell cycle. In contrast, treatment with MEL blocked the cells in late-S/G2 phase of the cell cycle and caused substantial apoptosis, regardless of bcl-2 expression. Major differences between DEX and MEL were also observed with respect to their effects on the levels of bcl-2 and p53. Whereas DEX induced an early (day 1) downregulation of bcl-2 (only in the cells with low bcl-2), treatment with MEL did not affect bcl-2 levels. The levels of bclx and bax remained unchanged following treatment with either MEL or DEX. These results, taken together, suggest that the two drugs target different cellular components and induce apoptosis by different pathways, and that resistance to DEX is associated with low levels of bcl-2, whereas resistance to MEL is independent of bcl-2, and therefore, in vivo resistance to MEL, observed in MM patients, might involve other mechanisms rather than bcl-2.

Solitary plasmacytoma of the spine associated with neurological complications.
    Spinal cord, 1998, Volume: 36, Issue:7

    We report eight patients with a solitary plasmacytoma of the spine associated with neurological complications. The patients included five men and three women with an average age at presentation of 59 years (range, 47 to 73 years). The tumour was confined to the thoracic spine in six cases, cervical spine in one and lumbar spine in one. Duration of symptoms ranged from 2.5 to 22 months. Treatment consisted of a combination of radiotherapy, melphalan and surgery. One patient progressed to multiple myeloma 7 years after surgery. Surgical treatment (anterior surgery in three cases and posterior surgery in five) produced neurological improvement in all patients. We stress the importance of an early diagnosis followed by appropriate treatment including surgery for this clinical entity and long-term follow-up to detect a disseminated disease.

Presence of a p53 gene deletion in patients with multiple myeloma predicts for short survival after conventional-dose chemotherapy.
    Blood, 1998, Aug-01, Volume: 92, Issue:3

    In multiple myeloma (MM), previous studies showed that mutations of the p53 gene are rare events in patients with newly diagnosed disease, but it is not known whether deletions of p53 are of any significance in MM. To address this question, we used interphase fluorescence in situ hybridization (FISH) with a DNA probe specific for the p53 locus at 17p13 and investigated bone marrow plasma cells from 72 patients with MM (59 patients = 81.9% before therapy). By FISH, deletions of p53, which were found to be predominantly monoallelic, were detected in 32.8% and 54.5% of patients with newly diagnosed and relapsed MM, respectively. Karyotypes from six of the patients with a p53 deletion by FISH showed a structural abnormality of 17p in only one of them. Additional FISH studies including a distal-17p probe (specific for the D17S34 locus) provided evidence for an interstitial deletion on 17p resulting in loss of p53 hybridization signals in myeloma cells. Among all 59 patients with newly diagnosed MM, presence of a p53 deletion was associated with stage III (P = .054), but not with other laboratory and clinical parameters. Patients with a p53 deletion had significantly shorter survival time compared with those without a deletion, both from the time of diagnosis (median 13.9 v 38.7 months; P < .0001) and from the time of initiation of induction treatment consisting of conventional dose chemotherapy (median 15.9 months v median not reached at 38 months; P < .0002). On stepwise multivariate regression analysis, presence of a p53 deletion was the most significant independent parameter predicting for shortened survival (P = .002). We conclude that a p53 gene deletion, which can be identified by interphase FISH in almost a third of patients with newly diagnosed MM, is a novel prognostic factor predicting for short survival of MM patients treated with conventional-dose chemotherapy.

Pyomyositis associated with Bacteroides fragilis in a patient with multiple myeloma.
    The American journal of tropical medicine and hygiene, 1998, Volume: 59, Issue:1

    Pyomyositis is an infection of the skeletal muscle that is usually caused by Staphylococcus aureus. We report a 68-year-old Japanese woman who developed pyomyositis caused by Bacteroides fragilis following treatment for multiple myeloma. There are only two cases of pyomyositis associated with multiple myeloma in the literature. After receiving melphalan and prednisolone for five days, she developed multiple abscesses in the muscles of the right arm and thigh. Purulent exudate was aspirated from the abscess, and B. fragilis was identified. This is the first case of B. fragilis pyomyositis. Magnetic resonance imaging aided the diagnosis. Treatment consisted of surgical incision and drainage, with antibiotic administration. The immunosuppression caused by the myeloma and/or the chemotherapy presented a risk factor for the unusual infection observed in this patient.

IgG1-kappa biclonal gammopathy associated with multiple myeloma suggests a regulatory mechanism.
    British journal of haematology, 1998, Volume: 102, Issue:2

    Multiclonal gammopathies associated with multiple myeloma may result either from a neoplastic transformation of a cell clone undergoing immunoglobulin class switching or from independent transforming events yielding proliferation of unrelated plasma cell clones. The simultaneous presence of more than one neoplastic clone may possess regulatory implications in terms of cell proliferation, clonal expansion, secretion of M-components or response to chemotherapy. We report a patient, diagnosed with multiple myeloma stage IIIa, who presented with two well-defined homogeneous IgG1-kappa components in the serum (designated WER-1 and WER-2) with striking differences in their plasma concentration and response to the classic melphalan/prednisone treatment. Immunochemical characterization and amino terminal sequence analysis of both the heavy and light chains of each M-component undoubtedly determined their biclonal origin. WER-1 was identified as IgG1(VHII)-kappaI while WER-2 was classified as IgG1(VHIII)-kappaIII. The plateau phase was characterized by very low or undetectable levels of WER-2, a high, almost constant, concentration of WER-1 and the absence of Bence Jones proteinuria, whereas these parameters were completely reversed during the escape phase with levels resembling those observed at the time of diagnosis. The statistically significant negative correlation between the biclonal components and the different susceptibility to the treatment clearly suggests regulatory interactions between the clones WER-1 and WER-2.

Quality-adjusted time without symptoms or toxicity analysis of interferon maintenance in multiple myeloma.
    Journal of clinical oncology : official journal of the American Society of Clinical Oncology, 1998, Volume: 16, Issue:8

    In a randomized trial conducted by the National Cancer Institute of Canada Clinical Trials Group (NCIC CTG), interferon alpha-2b (IFN) maintenance therapy (2 mU/m2 subcutaneously three times per week) after successful induction with melphalan and prednisone was found to prolong time to progression in patients with multiple myeloma. A favorable effect on survival was also present, but this difference was of borderline significance. However, IFN toxicity was a concern. To evaluate the trade-off between the clinical benefits of IFN and the associated toxicity, we applied the method of quality-adjusted time without symptoms or toxicity (Q-TWiST).. Three clinical health states were defined in this analysis: time with toxicity (TOX), time without disease relapse or toxicity (TWiST), and time following disease relapse (REL). Toxicity information for IFN had been collected using patient-completed diaries so the actual duration of each adverse event could be determined. The health states TOX and REL were weighted using utility scores to account for a possible decrement in quality of life, a weighted sum of the health state durations is used as a measure of quality-adjusted time.. The health state durations were calculated at 72 months median follow-up. Patients in the IFN group gained an average of 9.8 months without disease relapse (P = .001) and 5.8 months of overall survival (P = .074) versus the control group. However, the IFN group suffered an average of 4.1 months of moderate or worse toxicity (P < .001).. The clinical benefits of IFN outweigh the negative effects associated with treatment toxicity for a wide range of plausible utilities.

[The efficacy of polychemotherapy programs in treating multiple myeloma patients].
    Terapevticheskii arkhiv, 1998, Volume: 70, Issue:7

    To compare efficiency of the programs MCVP, VCAP and ARA-COP in the treatment of multiple myeloma (MM) as regards completeness of the response, duration of the remission and toxicity.. A total of 41 MM patients entered the study (27 females, 14 males, age from 41 to 72 years, MM duration from 1 month to 8 years). 16, 10 and 15 patients were treated according to MCVP, VCAP and ARA-COP programs.. Both in the resistant and primary patients the response was the highest to ARA-COP treatment. The remission or stabilization was achieved in 93.4% of patients. VCAP program was less effective. However, clinicohematological remission was achieved in 50% of patients. This program is rather heart toxic. MCVP program was the least effective. Survival was followed up in 16 patients (10 MCVP, 3 VCAP and 3 ARA-COP patients). The survival was 20-62, 16-36, 23.6-64.8 months for ARA-COP, VCAP and MCVP, respectively.. ARA-COP program proved most effective of the three programs both in primary and drug-resistant patients. VCAP and MCVP programs are less effective but can be used in primary management of MM patients.

[Rapid growth of glioblastoma during therapy for multiple myeloma: case report].
    No shinkei geka. Neurological surgery, 1998, Volume: 26, Issue:8

    Rapid growth of a glioblastoma during therapy for multiple myeloma is reported. A 53-year-old man was admitted to our hospital with a right costal tumor, which was resected. The diagnosis was plasmocytoma. Urine protein electrophoresis showed a monoclonal peak in the region of gamma-globulin, and examination of the bone marrow revealed 17.8% of atypical plasma cells. Brain magnetic resonance (MR) imaging detected two small lesions, but these could not be identified as brain tumor. He received chemotherapy (melphalan 10 mg/day and predonin 30 mg/day for 4 days) and was discharged. Two weeks after discharge, he was readmitted because of left hemiparesis. T1-weighted MR imaging showed two large hypointense lesions in the right frontal lobe, with ring-like enhancement following Gd-DTPA infusion. 1H-MR spectroscopy showed typical findings of tumor with increased choline and lactic acid peaks. 201Tl SPECT revealed high accumulation in both early and delayed images. Right carotid angiography showed a hypervascular tumor with venous filling and mass effect. The lesions were resected via right frontal craniotomy, followed by intraoperative radiation and placement of an Ommaya reservoir. Histological examination showed the tumors were glioblastoma. The brain between the tumors also showed the typical appearance of glioblastoma, suggesting that the lesions were continuous. Postoperatively, the patient's left hemiparesis disappeared. He received local irradiation and chemotherapy and was then discharged. Coexistence of glioblastoma and multiple myeloma is rare. The cause may be genetic abnormality, but immunodeficiency due to multiple myeloma, surgical damage, or chemotherapy may have contributed to the rapid growth of the glioblastoma.

Multiple myeloma index: verification of a new prognostic approach with evaluation of treatment response.
    Haematologica, 1998, Volume: 83, Issue:8

    Currently adopted prognostic criteria for multiple myeloma (MM) still lack reliable predictive ability to select subsets of patients for different therapies, in particular for intensive treatment protocols. In this work we aimed to test the prognostic value of the MM Prognostic Index (MMPI), developed in 1996 by Grignani et al. from Pavia University as a clinical and investigational tool.. Ninety-three MM patients were eligible for the study. All received initial induction therapy based on a standard 6-month melphalan + prednisone (M + P) protocol. Clinical and laboratory parameters, conventional staging and bone marrow infiltration percentage and cytopathology (BMIC) were assessed at diagnosis, while treatment response (TR) was evaluated using criteria after induction therapy. Cox's multivariate survival analysis was applied on prognostic data.. In our patients independent prognostic value was confirmed for British Medical Research Council staging, BMIC and TR, the three factors considered in MMPI. Risk classes obtained via MMPI identify patients with different outcomes; moreover, the index discriminates significantly among Stage II patients.. This new approach to MM prognosis is simple and reliable from the prognostic point of view; it refers not only to neoplastic mass, but also to intrinsic proliferative capacity of the malignant clone and to tumor-host interactions. We recommend its adoption in clinical practice and in the evaluation and design of therapeutic trials.

The use of intravenous intermediate dose melphalan and dexamethasone as induction treatment in the management of de novo multiple myeloma.
    European journal of haematology, 1998, Volume: 61, Issue:5

    The variable absorption of melphalan from the gastrointestinal tract results in response rates between 40 and 60%. High dose melphalan increases response rates but at the cost of increased morbidity and mortality. We have investigated intravenous intermediate dose melphalan and dexamethasone in the treatment of patients presenting with de novo multiple myeloma with the object of reducing toxicity while preserving an improved response rate compared to oral melphalan and prednisolone. The results show that this treatment can be delivered safely on an outpatient basis in patients up to the age of 78 yr; 82% of patients achieved an objective response and 30% a complete haematological and clinical remission. Median overall survival for the whole group is 37 months.

Costs of intensive treatment and follow-up of patients with multiple myeloma.
    Anti-cancer drugs, 1998, Volume: 9, Issue:10

    In a retrospective study, we calculated the treatment and follow-up costs of patients with newly diagnosed multiple myeloma. The total treatment programme consisted of eight phases: VAD or VAMP chemotherapy, follow-up I, high-dose melphalan followed by transplantation of whole blood, follow-up II, collection of peripheral blood progenitor cells by leukapheresis, follow-up III, high-dose chemotherapy (busulfan/cyclophosphamide) followed by reinfusion of peripheral stem cells and follow-up IV (until 3 months from hospital discharge after peripheral stem cell transplantation). For each phase the average costs were calculated for all patients who were on treatment/follow-up in each particular phase. The total average cumulative costs of treatment and follow-up of all patients amounted to US$49850. Considering only the patients who completed the total treatment programme as it was scheduled, the average total treatment and follow-up costs were US$44800. The average costs of treatment and follow-up of patients who did not complete the programme as it was scheduled (patients who died, patients who were withdrawn from treatment and patients who received additional treatment) were US$57025.

Establishment of a monoclonal antibody to human myeloma cell: relation to chemotherapy and extramedullar infiltration.
    Medical oncology (Northwood, London, England), 1998, Volume: 15, Issue:4

    Resistance of myeloma cells to melphalan (L-PAM) is a serious problem. To investigate mechanisms of drug resistance, we generated a monoclonal antibody, clone O3, to melphalan-resistant myeloma cells, KHM-11R. Western blot analysis showed that molecular weight of O3 antigen was approximately 90 kDa. Expression of O3 antigen was approximately two times higher in KHM-11R than in parental melphalan sensitive cell line, KHM-11. O3 was preferentially expressed in plasma cell, B-cell, and monocytic cell lines, but not in T-cell lines. Analysis of bone marrow samples from myeloma patients revealed that 13 of 23 samples expressed O3 antigen at various levels, and that O3 antigen expression in patients correlate with preceding chemotherapy, advanced clinical stage and extramedullar invasion of myeloma cells. Furthermore, patients expressing O3 antigen at the time of diagnosis tended to have poor prognosis. The investigation of O3 antigen in myeloma cells will be useful to reveal the pathophysiology of extramedullar invasion and the mechanism of cell killing by melphalan.

[Multiple myeloma nephropathy as a cause of renal failure--diagnostic difficulties and prospects for treatment].
    Polskie Archiwum Medycyny Wewnetrznej, 1998, Volume: 100, Issue:3

    We describe two patients admitted to our hospital because of renal failure. We diagnosed multiple myeloma in both. One patient had high peripheral blood eosinophilia, that normalized during therapy. The patients were treated with melphalan and prednisone, hemodialysis and one patient with recombinant human erythropoietin. Both patients responded to that treatment: after 7 months the number of plasma cell in bone marrow decreased from 65 to 10% in the first patient, and from 38 to 4% in the second patient. They returned to work and were on maintenance hemodialysis 2 times weekly. The patients have been observed for 21 months.

Multicyclic, dose-intensive chemotherapy supported by hemopoietic progenitors in refractory myeloma patients.
    Bone marrow transplantation, 1997, Volume: 19, Issue:1

    Attempts to increase dose intensity have been hampered by hematologic toxicity. To address this issue, we designed a study to determine whether the reinfusion of PBPC significantly reduces the toxicity of multicyclic dose-intensive chemotherapy. Thirty refractory patients, median age 63, received CY 3 g/m2 plus melphalan 60 mg/m2 followed by PBPC and G-CSF (CM regimen). CY (at day 0) and G-CSF were used to mobilize PBPC harvested by a single leukapheresis at day 10. Melphalan was infused at day 11. PBPC were kept unprocessed at 4 degrees C for 48 h and reinfused at day 12. This regimen was repeated three times every 6 months. Outcomes were compared with those of 30 similar patients treated with melphalan 30 mg/m2 followed by G-CSF only, and repeated every 2 months for a total of six cycles. In patients receiving CY plus melphalan followed by PBPC reinfusion, the median duration of neutropenia (ANC < 500/microliters) and thrombocytopenia (platelets < 2500 microliters) was only 5 and 2 days respectively, and did not increase after the subsequent courses. Hematologic toxicity was quite similar to that observed after melphalan 30 mg/m2 plus G-CSF. The CM regimen was followed by 30% complete remission and 86% response > 50%, melphalan 30 mg/m2 by no complete remissions and 38% response > 50%. Patients receiving CM regimen showed a longer progression-free survival (22 vs 10 months, P < 0.01). The dose intensity of melphalan can be doubled by reinfusing PBPC without increasing toxicity. The combination of CY and melphalan followed by PBPC improves response rate and outcome when compared to low-dose melphalan.

Conventional induction treatments do not influence overall survival in multiple myeloma.
    British journal of haematology, 1997, Volume: 96, Issue:2

    A retrospective analysis was performed on two subsequent myeloma patient series treated with the same conventional induction treatments, melphalan and prednisone or alternating VMCP/VBAP: 273 were enrolled in the multicentre M83 trial (M83 trial group) from 1983 to 1986; 160 were referred to a single institution (Haemat. To group) from 1986 to 1994. Response to treatment was very similar in the two groups (53% v 50.3%). Remission duration curves merely overlapped (median 20 v 21 months). However, overall survival was significantly longer in the Haemat. To group (43.2 v 33 months, P < 0.04). This difference was due to a prolonged period from relapse or progression to death (21 v 8 months, P < 0.01; 20.8 v 7 months, P < 0.009). Prolonged survival was also observed in poor-prognosis patients with a serum beta2-microglobulin level > 3 mg/l, in the Haemat. To group (31.8 v 24.2 months, P < 0.04). The same induction treatments produced almost identical response rate and remission duration in both groups, but overall survival was 10 months longer for one group. However, it could be argued that treatment salvage modalities and support therapies have been improved in a decade. Lastly, induction treatments did not influence overall survival.

    To describe a patient with Alzheimer disease and multiple myeloma (with Bence Jones proteinuria) with improvement of both conditions following cytotoxic chemotherapy, and to present issues related to the pathogenesis and management of Alzheimer disease.. Report of a case.. Progressive dementia and myeloma developed in a 64-year-old man. Cytotoxic chemotherapy for the myeloma resulted in maintained improvement of the dementia. Clinical, neuropsychological, pathological, and laboratory data are presented.. For 2 years, vincristine sulfate, carmustine, melphalan, cyclophosphamide, and prednisone were administered cyclically, and the patient's dementia and lambda light chain production improved. Severe dementia recurred before death and cessation of therapy, although light chain production remained decreased.. Dementia improvement with cytotoxic (ie, immunosuppressive, anti-inflammatory) therapy may offer insight into the pathogenesis and management of Alzheimer disease.

Feasibility and cost-effectiveness of outpatient autotransplants in multiple myeloma.
    Bone marrow transplantation, 1997, Volume: 20, Issue:6

    This report summarizes 2 years experience in performing 336 autotransplant procedures in 251 consecutive patients with multiple myeloma, using high-dose melphalan at 200 mg/m2 in the context of a tandem transplant program. A total of 91 patients received 118 transplants as outpatients while the remaining 160 patients received 218 transplants as inpatients. Outpatients were more often younger, with better stem cell products, normal serum albumin and beta-2-microglobulin levels as well as chemotherapy-sensitive disease compared to inpatients. There were no differences in hematopoietic recovery and non-hematologic toxicities between outpatient and inpatient transplant recipients. Post-transplant febrile neutropenia and most other post-transplant toxicities were managed successfully in an ambulatory setting. Although liberal criteria were developed for hospitalization of outpatients, including clinical parameters as well as patient desire and physician/nurse judgement, only 21% of outpatients required admission after transplantation. Median hospital stay for these outpatients was 9 days, while inpatients were hospitalized for a median of 15 days (P = 0.0001). After adjusting for differences in disease and host features, our study showed outpatient management resulted in significant financial savings due to lower pharmacy (42%), hospitalization (50%) and pathology/laboratory charges (36%). We conclude that outpatient transplants should facilitate access to myeloablative therapy, thereby improving complete remission rates and survival of myeloma patients.

Factors influencing collection of peripheral blood progenitor cells following high-dose cyclophosphamide and granulocyte colony-stimulating factor in patients with multiple myeloma.
    British journal of haematology, 1997, Volume: 98, Issue:3

    We treated 103 multiple myeloma (MM) patients with 7 g/m2 cyclophosphamide (Cy) followed by 300 micrograms G-CSF/d to harvest peripheral blood progenitor cells (PBPC). PBPC autografts containing > 2.0 x 10(6) CD34+ cells per kg body weight were obtained at the first attempt from 90/100 evaluable patients. The most significant factor predicting impairment of PBPC collection was the duration of previous melphalan treatment (P < 0.0001). In multivariate discriminate analysis, treatment with melphalan during the most recent chemotherapy cycles prior to mobilization (P = 0.0727) and previous radiotherapy (P = 0.0628) had a marginally significant negative influence on the efficacy of PBPC collection. We found no reduced functional capacity of CD34+ cells to restore haemopoiesis after myeloablative treatment related to the duration of melphalan exposure. At the time of best response to conventional treatment, a median paraprotein reduction of 21% was achieved following high-dose cyclophosphamide (HD-Cy). Two heavily pretreated patients died and one patient developed pulmonary toxicity W.H.O. grade IV following HD-Cy. Potential transplant candidates should undergo mobilization and harvesting of PBPC before melphalan-containing treatment. Combinations of haemopoietic growth factors and their dose-modifications should be investigated to improve PBPC collection, to allow a dosage reduction of the mobilization chemotherapy.

Serum beta-2-microglobulin in patients with multiple myeloma treated with alpha interferon.
    Journal of medicine, 1997, Volume: 28, Issue:5-6

    In ten patients with multiple myeloma (MM), serum beta-2-microglobulin (B2M) levels were monitored in order to clarify the influence of alpha interferon (IFN) administration. Despite decreases in M-protein and the absence of renal dysfunction, the levels of serum B2M were sustained above those prior to melphalan-prednisolone and IFN therapy in seven patients with MM for six months. Serum B2M did not increase in ten patients with MM treated only by melphalan-prednisolone. Furthermore, serum B2M levels in a patient who achieved a complete response were sustained above her prior level and returned to normal after cession of IFN therapy. Our study suggests that the serum B2M level is increased by treatment with IFN, and does not prove the condition of the disease.

    High dosage melfalan chemotherapy with subsequent autologous blood stem cell transplantation in suitably selected patients with multiple myeloma greatly increases the probability that complete remission will be achieved and it prolongs the mean survival period as compared with classical chemotherapy. Till recently patients with multiple myeloma and renal insufficiency were not included in transplantation programmes. Only recently several papers were published abroad which indicate the possibility to implement transplantations also in these patients. The authors describe the treatment, incl. the first autologous transplantation of blood stem cells in a patient with multiple myeloma and renal insufficiency.

[Scleredema, acanthosis nigricans and IgA/Kappa multiple myeloma].
    Annales de dermatologie et de venereologie, 1997, Volume: 124, Issue:8

    Scleredema is an uncommon disease of unknown origin. Characteristic thick skin with symmetrical diffuse induration develops. The infiltration begins on the face and neck then extends to the root of the upper limbs and trunk. There are three clinical types of scleredema. The first is preceded by an upper airway infection and progresses rapidly before regressing spontaneously within a few months. The second type is associated with chronic diabetes. The third type is associated with monoclonal gammapathy, rarely of myelomatous type, and develops insidiously. Acanthosis nigricans can be a paraneoplastic syndrome, often associated with a gastrointestinal cancer. Few cases associating scleredema and acanathosis nigricans have been reported.. A 56-year old woman had developed scleredema over the last 6 years when acanthosis nigricans appeared together with IgA kappa multiple myeloma. Treatment with melphalan and prednisolone was effective against the myeloma as well as the scleredema and acanthosis nigricans.. Only five cases of associated scleredema and multiple myeloma have been reported, four with kappa IgG myeloma and one with IgA myeloma. An association between acanthosis nigricans and sclerederma could be coincidental although the fact that the different manifestations regressed together after the myeloma treatment would suggest some relationship between these three diseases.

Lymphocyte recovery and clinical response in multiple myeloma patients receiving interferon alpha 2 beta after intensive therapy.
    British journal of cancer, 1996, Volume: 73, Issue:2

    The recovery of immunoregulatory cells in the peripheral blood of patients with multiple myeloma receiving maintenance therapy with interferon alpha 2 beta (IFN-alpha 2 beta) after intensive therapy with high-dose melphalan and autologous bone marrow or peripheral blood stem cell rescue was studied. IFN-alpha 2 beta significantly inhibited the recovery of CD3+, CD4+, CD8+, CD56+/CD3- and CD16+/CD3- lymphocytes compared with numbers found in patients who had no further post-transplant treatment, but had no effect on the recovery of CD19+ cells. Among patients who did not receive IFN-alpha 2 beta, the number of CD8+, CD56+/CD3- and CD16+CD3- lymphocytes recovered to values similar to normal volunteers with increasing time after intensive therapy, however the number of CD4+ cells remained significantly below levels found in normal volunteers. Although CD16+/CD3- and CD56+/CD3- cell numbers were reduced in patients receiving IFN-alpha 2 beta, natural killer (NK) activity was not affected. The levels of soluble interleukin 2 receptor (sIL-2R) were similar in all patients and IL-2 was not detected in any patient. At the time of writing, of the total of 69 patients, seven have relapsed, of whom three were receiving IFN-alpha 2 beta, however there was no correlation between the absolute numbers of any lymphocyte subset with imminent relapse. The data suggest that the recovery of a specific lymphocyte subset(s) in peripheral blood is unlikely to be associated with the maintenance of response after intensive therapy.

Trisomy 8 preceding diagnosis of acute nonlymphocytic leukemia by 2 years in a patient with multiple myeloma without cytological evidence of myelodysplasia.
    Annals of hematology, 1996, Volume: 72, Issue:2

    A case of acute nonlymphocytic leukemia (ANLL) occurring 2 years after the diagnosis of multiple myeloma (MM) that had been treated by only one course of melphalan/prednisone chemotherapy is reported. Cytogenetic and fluorescence in situ hybridization analysis of peripheral blood cells revealed trisomy 8 as the sole cytogenetic defect at the time of diagnosis of ANLL. Two years earlier, when MM was diagnosed without any cytological evidence of co-existent myelodysplasia, chromosomal analysis of bone marrow cells showed the same pathological karyotype 47, XY, +8 in 14 of 20 mitoses studied. Our interpretation of this unusual cytogenetic finding is that at the time of diagnosis of MM, in spite of lacking cytological signs of myelodysplasia, an unrecognizable myelodysplastic syndrome must have been present which then evolved to ANLL.

Peripheral blood progenitor cell collections in multiple myeloma: predictors and management of inadequate collections.
    British journal of haematology, 1996, Volume: 93, Issue:1

    Thirty-seven patients with previously treated multiple myeloma (MM) underwent peripheral blood progenitor cell (PBPC) collection following high-dose cyclophosphamide and GM-CSF or sequential IL-3 and GM-CSF. Patients with an inadequate collection were considered for a second or third collection. 25 patients underwent subsequent autotransplant. The only variable predictive of CFU-GM yield was the extent of prior melphalan therapy. All repeat collections were unsuccessful and patients infused with an autograft obtained from multiple sets of collections had a high incidence of delayed engraftment. We conclude that melphalan should be avoided or PBPC collection performed early in the disease course in patients who are potential transplant candidates.

Comparison of the effects of 2-chlorodeoxyadenosine and melphalan myeloma cell lines.
    Leukemia research, 1996, Volume: 20, Issue:2

    We have studied the effects of 2-chlorodeoxyadenosine (2-CdA) and melphalan on DNA synthesis and cell proliferation of five myeloma cell lines and one primary culture of highly purified myeloma cells. The DNA synthesis was estimated by thymidine incorporation and cell death was estimated by a coluorimetric assay sensitive to mitochondrial activity. The concentrations of 2-CdA giving 50% inhibition of DNA synthesis (ID50) in four cell lines were 8, 100, 500 and 2500 nM, whereas the corresponding concentrations of melphalan were 600, 600, 1000 and 7500 nM, respectively. In one cell line, the ID50 for melphalan was 400 nM, whereas 2-CdA apparently was without inhibitory effect and the ID50 was not reached. The ID50 for 2-CdA in the primary culture was 250 nM. When compared on a molar basis, 2-CdA had a more potent inhibitory effect than melphalan on four out of five myeloma cell lines. This is in contrast to clinical experiments which have shown lack of effect of 2-CdA in myeloma patients. Our study shows that 2-CdA has a marked heterogeneous effect on myeloma cell lines and opens up the possibility that a similar variation in sensitivity may also exist among myeloma cell clones in vivo.

Whole blood harvested after granulocyte-colony stimulating factor (Neupogen) mobilization, and reinfused unprocessed after high-dose melphalan treatment, accelerates hematopoietic recovery in patients with multiple myeloma.
    Cancer, 1996, Mar-15, Volume: 77, Issue:6

    High-dose melphalan (HDM) is now a standard treatment for multiple myeloma (MM). Stem cell transplants are fast evolving as an alternative to bone marrow transplants because they are less traumatic and easier to perform. A study was undertaken to test if whole blood harvested after mobilizing peripheral blood stem cells with granulocyte-colony stimulating factor (G-CSF) reinfused as such (without stem cells being processed or concentrated through a cell separator) for rescue after HDM (dose 140-180 mg/m2) in MM accelerates hematopoietic recovery.. Eight consecutive patients with MM were given HDM after receiving 4-5 courses of infusional vincristine, doxorubicin, and dexamethasone (VAD) chemotherapy. Approximately 6 weeks after the last course of chemotherapy, at the start of the procedure, G-CSF (Neupogen) was given at a dose of 10 microgram/kg subcutaneously daily for 4 days to mobilize stem cells. All of the patients had brisk leukocytosis (18.4-64.6 x 10(9)/L). On day 0 (fifth day after G-CSF), 1 L of blood was removed by phlebotomy and kept at room temperature for 24 hours. This was followed by a rapid intravenous (i.v.) bolus of melphalan at a dose of 140 mg/m2 in the first three patients, 155 mg/m2 in the 4th, 170 mg/m2 in the 5th, and 180 mg/m2 in the 6th, 7th, and 8th patients, applies to all patients along with hydration and diuresis. Twenty-four hours later, I L of blood previously removed was transfused back to the patient without any processing through the cell separator. The numbers of mononuclear cells reinfused was between 0.76 and 3.2 x 10(8)/kg (mean: 1.82 x 10(8)/kg). The number of CD 34+ cells infused in 4 patients ranged from 1.9 to 2.8 x 10(6)/kg (mean: 2.35 x 10(6)/kg). G-CSF was restarted on day 2 at a dose of 5 microgram/kg and given daily until the granulocyte count was 0.5 x 10(9)/L or more for 3 consecutive days. Antibiotics were given whenever a patient developed pyrexia. Platelets were transfused if below 20 x 10(9)/L or for incidences of overt bleeding.. Granulocyte counts touched 0 between Days 6 and 10, lasting for an average of 3.4 days. Duration of granulocyte count below 0.5 x 10(9)/L was 6.5 days (range: 5-9), and these rose to 1.0 or more x 10(9)/L by Day 13.7 (range: 13-16). The number of platelet transfusions given per patient was 2.5 (range: 0-4). Intravenous antibiotics were used for 9 days (range: 4-12), and patients were discharged on Day 19 (range: 16-22). Follow-up ranged from 45 to 380 days.. Hematopoietic recovery was rapid in all patients, including those who received doses of melphalan higher than 140 mg/m2. This resulted in less need for platelet transfusions or antibiotics, and hospitalization was short. Our results are historically similar to conventional peripheral blood stem cell transplants but much better than autologous bone marrow transplants, indicating that whole blood after G-CSF provided sufficient progenitor cels for early engraftment. The procedure is less labor intensive insofar as it does not require separation and concentration of stem cells. It has the potential of becoming an alternative to autologous marrow and peripheral blood stem cell transplantation in patients with MM.

Reversible metastatic pulmonary calcification in a patient with multiple myeloma.
    Annals of hematology, 1996, Volume: 72, Issue:5

    A-52-year-old patient presented with a 2-year history of multiple myeloma, recurrent episodes of hypercalcemia, and extensive bone involvement. She developed pulmonary infiltrates, initially misdiagnosed as interstitial pneumonia. High-resolution computed tomography and bone scintiscanning indicated pulmonary calcification, which was confirmed by a transbronchial biopsy. Cytostatic treatment of multiple myeloma in combination with repetitive i.v. administration of bisphosphonates over a period of 6 months led to a significant improvement of clinical symptoms. Regression of pulmonary infiltrates was demonstrated by chest radiograph and computed tomography. There are only a few reports on pulmonary calcification in patients with multiple myeloma; the condition was associated mostly with progressive disease, kidney failure, adult respiratory distress syndrome and bad prognosis. In our patient isolated calcification of the lungs without involvement of other organ systems was successfully treated. These findings suggest that interstitial pulmonary calcinosis in multiple myeloma can be reversed by normalization of serum calcium levels using bisphosphonates combined with cytostatic treatment.

IgD multiple myeloma. A report of three cases.
    Minerva medica, 1996, Volume: 87, Issue:3

    Three patients suffering from IgD myeloma, which a rare variant of multiple myeloma which often has an aggressive course, were studied retrospectively in order to elucidate the existence of clinical or laboratory features in relationship to survival time. The patients were monitored in follow-up for a time variable for 8 to 52 months. All patients received courses of chemotherapy using an association of Melphalan and Prednisone (MP); one patient also received recombinant interferon alpha in association. Response to chemotherapy, with a > 50% reduction of serum M component, disappearance of Bence Jones proteinuria and permanent control of the disease was achieved in all patients. The median duration of survival in IgD myeloma is shorter than that currently observed in patients with other myeloma types: in our series one patient died 8 months after diagnosis but other two patients are still alive 8 and 52 months after diagnosis, respectively. Great difficulty was encountered in analysis of unfavourable prognostic clinical and laboratory data: in our series, in spite of the small number of cases, the Authors observe that only the relief of increased serum levels of Lactate Dehydrogenase (LDH) seem to be in relationship with a trend of shorter survival. The authors, confirming the particular clinical and laboratory aspects of this myeloma, stress that there may coexist cases in which standard chemotherapy failed to control the diseases: these seem to indicate neoplasia with fast growth kinetics. Further studies are necessary in order to identify new prognostic index which allows the identification of selected groups of patients who can profit from a combination chemotherapy regimen other than the standard MP association.

Autotransplants in multiple myeloma: what have we learned?
    Blood, 1996, Aug-01, Volume: 88, Issue:3

    Of 496 consecutive patients with multiple myeloma (MM) enrolled in clinical trials of tandem transplants with peripheral blood stem cells support, 470 (95%) completed the first autotransplant with melphalan 200 mg/m2 (MEL 200) and 363 (73%) completed the second transplant with either MEL 200 (40%), MEL 140 mg/m2 (MEL 140) with total-body irradiation (17%), or a combination of alkylating agents (16%), depending on the response status prior to the second transplant; 31 patients up to age 60 years received an allograft as the second transplant. The median interval from first to second transplant was 5 months. Treatment-related mortality during the first year after transplantation was 7%, and complete remission (CR) was obtained in 36%; the median durations of event-free survival (EFS) and overall survival (OS) after transplant were 26 and 41 months, respectively. Low beta 2-microglobulin ([B2M] < or = 2.5 mg/L) and C-reactive protein ([CRP] < or = 0.4 mg/dL) were the most significant standard parameters associated with both prolonged EFS and OS. Median OS exceeded 5.5 years in the one third of patients with both low B2M and CRP. When cytogenetics were included in the analysis, the presence of 11q abnormalities and/or complete or partial deletion of chromosome 13 ("unfavorable karyotype") became a dominant negative feature for both EFS and OS. In addition to these pretransplant parameters, attainment of CR and application of two transplants within 6 months both significantly extended EFS and OS. The group of patients (7%) with high B2M and CRP with either IgA isotype or unfavorable karyotype had the worst prognosis (EFS, < or = 10 months; median OS, < or = 12 months) and will require novel therapy. We conclude that tandem transplants are feasible in the majority of patients up to age 70 years, effecting CR in one third of all patients. Median OS was greater than 5.5 years, regardless of pretransplant features, if the first transplant was applied within 12 months of initial treatment and the second transplant no more than 6 months later.

High-dose carmustine, etoposide and melphalan ('BEM') with autologous stem cell transplantation: a dose-toxicity study.
    Bone marrow transplantation, 1996, Volume: 17, Issue:3

    We have investigated the toxicity of dose-escalation of BCNU, etoposide and melphalan ('BEM') chemotherapy with autologous stem cell transplantation in patients with haematological malignancies. Seventy-two patients with haematological malignancies were treated with BCNU (600 mg/m2, 450 mg/m2 or 300 mg/m2), etoposide 2 g/m2 and melphalan 140 mg/m2 followed by autologous bone marrow transplantation (ABMT), n = 51, or autologous peripheral blood progenitor cell transplantation (APBPCT), n = 21. Liver and pulmonary function was monitored pretransplant and at regular intervals post-transplant. Mucositis was graded daily during in-patient stay. There was a significantly higher incidence of symptomatic pulmonary toxicity in the patients who received BCNU at 600 mg/m2 than in the other two groups, and there was a significant increase in the incidence of asymptomatic decrease in carbon monoxide (KCO) in the patients who received BCNU 450 mg/m2. There was no significant difference between the three groups in the incidence and severity of mucositis or in the incidence of transiently abnormal liver function. We conclude that etoposide at 2 g/m2 can be used without unacceptable mucositis. BCNU at 600 mg/m2 is associated with an unacceptably high incidence of lung toxicity, but at 450 mg/m2 there is minimal symptomatic lung toxicity.

Kaposi's sarcoma after autologous bone marrow transplantation for multiple myeloma.
    Bone marrow transplantation, 1996, Volume: 17, Issue:4

    We report a case of Kaposi's sarcoma in a patient who underwent autologous bone marrow transplantation (ABMT) for multiple myeloma. Four months after ABMT he presented with numerous asymptomatic, dark blue and purplish macules and nodules on the trunk and lower extremities. Biopsy revealed the typical histologic pattern of Kaposi's sarcoma. The patient died due to disseminated Kaposi's sarcoma while in complete remission of his hematologic malignancy.

Hyperlipidemia associated with multiple myeloma.
    Internal medicine (Tokyo, Japan), 1996, Volume: 35, Issue:4

    A 70-year-old woman with type IIb therapy-refractory hyperlipidemia was diagnosed as having IgA kappa type multiple myeloma. She had neither a family history nor any other disease known to accompany hyperlipidemia. The serum IgA concentration fell from 3.42 g/dl to 1.24 g/dl following chemotherapy with melphalan and prednisolone, and a concomitant decrease in both the serum cholesterol and triglyceride levels was observed. These serum lipids were positively correlated with the serum IgA concentration (p < 0.001) during the three cycles of chemotherapy. These findings suggest the involvement of the monoclonal protein of IgA in the development of hyperlipidemia in the present case.

A pilot study of 220 mg/m2 melphalan followed by autologous stem cell transplantation in patients with advanced haematological malignancies: pharmacokinetics and toxicity.
    British journal of haematology, 1996, Volume: 95, Issue:3

    We studied the pharmacokinetics and toxicity of 220 mg/m2 melphalan (HDM 220) followed by autologous stem cell transplantation in 16 patients with advanced haematological malignancies. Pharmacokinetic parameters (mean values of steady-state volume of distribution 14.6 l/m2, total body clearance 313 ml/min/m2, elimination half-life 46 min) were the same as those of 140 or 200 mg/m2 melphalan in previous reports. HDM 220 was feasible. Extramedullary toxicity was mainly W.H.O. grade 4 mucositis (13/16 patients). The median duration of 41 d (10, not reached) of thrombocytopenia < 25 x 10(9)/l was long. In multiple myeloma the response rate was 89% in heavily pretreated patients, suggesting that HDM 220 could be considered earlier in the course of the disease as an alternative consolidation therapy.

[Monoclonal rheumatoid factor in a patient with multiple myeloma after chemotherapy].
    Nihon Rinsho Men'eki Gakkai kaishi = Japanese journal of clinical immunology, 1996, Volume: 19, Issue:5

    A patient with multiple myeloma was treated with several cycles of chemotherapy and developed monoclonal IgA rheumatoid factor. The monoclonal rheumatoid factor in this case reacted with 2 types of monoclonal antiidiotypic antibody derived from monoclonal rheumatoid factors in a patient with Sjögren's syndrome and a patient with macroglobulinemia. Two possible mechanisms accounting for the development of rheumatoid factor activity during a course of chemotherapy are discussed. The first possibility is that the rheumatoid factor or activity had been initially covered by an antiidiotypic antibody but was disclosed by the decreased production of this antibody following by the immunosuppressive therapy. The second possibility is that monoclonal IgA acquired rheumatoid factor activity by a point mutation resulting in a change in the molecular structure of the idiotype.

Safety of autotransplants with high-dose melphalan in renal failure: a pharmacokinetic and toxicity study.
    Clinical cancer research : an official journal of the American Association for Cancer Research, 1996, Volume: 2, Issue:6

    Melphalan (MEL) is probably the most effective chemotherapeutic agent in multiple myeloma (MM) with a clear dose-response effect. It can be escalated without excessive toxicity to 200 mg/m2, a myeloablative dose requiring hematopoietic stem cell support. Patients with marked renal insufficiency, not an infrequent finding in MM, have either received reduced doses or have been excluded from therapy with high-dose MEL. A prospective study was performed to evaluate the relationship between MEL pharmacokinetics and renal function in 20 patients with MM. Six patients had severe renal insufficiency (creatinine clearance, <40 ml/min), including five on chronic hemodialysis. Three patients with severe renal impairment first received a low test dose of MEL (16 mg/m2) for pharmacokinetic studies. All patients received 200 mg/m2 MEL divided into two equal doses of 100 mg/m2 i.v. on 2 consecutive days, followed by the administration of peripheral blood stem cells. MEL pharmacokinetics, performed after the first dose of 100 mg/m2, was not adversely affected by impaired renal function. The median half-life (t1/2), area under the concentration curve, and clearance of MEL were 1.1 h, 5.5 mg h/liter, and 27.5 liter/h, respectively, in patients with a creatinine clearance of <40 ml/min compared to 1.9, 7.9, and 23.6 for the others. Renal insufficiency also had no apparent negative impact on the quality of peripheral blood stem cell collections and did not adversely affect posttransplant engraftment, transfusion requirements, incidence of severe mucositis, or overall survival. However, it was associated with longer durations of fever (P = 0. 0005) and hospitalization (P = 0.004). No transplant-related deaths were observed. Plasma t1/2 and area under the concentration curve differed by a factor of 10 and MEL clearance by a factor of 5 between patients with the lowest and highest values. These large variations in MEL elimination could not be explained by patient or disease characteristics. We conclude that renal failure does not require dose reduction of MEL in autologous transplant. Due to marked interindividual variation in MEL elimination, pharmacokinetically guided dosing as well as cellular pharmacology studies may be helpful in achieving a more uniform antitumor effect.

Assessment of the therapeutic potential of cytokines, cytotoxic drugs and effector cell populations for the treatment of multiple myeloma using the 5T33 murine myeloma model.
    Immunology and cell biology, 1995, Volume: 73, Issue:4

    The therapeutic potential of six cytokines, eight cytotoxic drugs and two effector cell populations for the treatment of multiple myeloma was assessed in vitro using the 5T33 murine myeloma model. The efficacy of combination IFN-alpha and melphalan therapy was also evaluated in vitro and in vivo. Of the cytokines tested in vitro using the MTT assay, only IFN-alpha demonstrated significant inhibition of myeloma cell growth at non-toxic concentrations (ED50 = 1508.3 +/- 181.3 U/mL and 2617.9 +/- 334.0 U/mL for murine IFN-alpha [mIFN-alpha] and human IFN-alpha hybrid B/D [hIFN-alpha B/D], respectively). The ED50 for the eight cytotoxic drugs tested ranged from 2.3 x 10(-9) to 4.3 x 10(-13) mol/L and all were within the therapeutic range for humans. Combination hIFN-alpha B/D and melphalan were found to be additive in their inhibitory effects on myeloma cell growth in vitro and this finding was confirmed in vivo in C57BL/KaLwRij mice bearing disseminated 5T33 myeloma. Control animals demonstrated a median survival duration of 25.3 days whereas hIFN-alpha B/D or melphalan treatment alone increased survival to 30.5 and 33.3 days, respectively (P < 0.001). Combination IFN-alpha/melphalan therapy increased median survival duration to 38.5 days (P < 0.001) which was also significantly greater than that obtained with single agent therapy (P < 0.01). The murine myeloma cells were found to be resistant to NK cell lysis but susceptible to lysis by LAK cells (49.3 +/- 6.3% lysis at an effector to target ratio of 100:1).(ABSTRACT TRUNCATED AT 250 WORDS)

In multiple myeloma, clonotypic B lymphocytes are detectable among CD19+ peripheral blood cells expressing CD38, CD56, and monotypic Ig light chain.
    Blood, 1995, Jan-15, Volume: 85, Issue:2

    Multiple myeloma (MM) is characterized by a plasma cell infiltrate of the bone marrow (BM). However, late-stage monotypic B cells have been detected in the blood. This work analyzes the effects of clinical treatment on late stage CD19+ B cells present in 752 blood samples from 152 MM patients. MM patients have 2 to 8 times as many circulating CD19+ cells as do normal donors. Analysis of the Ig heavy chain (IgH) gene rearrangements using polymerase chain reaction indicates that the CD19+ population includes cells sharing the same clonotypic CDR3 region as is detected in the BM plasma cells, for patients analyzed during chemotherapy or in relapse. They are also monotypic as defined by their cytoplasmic or surface expression of Ig kappa or lambda light chain. The light chain restriction is the same as that of the BM plasma cells. Individual patients observed over 1- to 2-year periods exhibit considerable variation in the number of B cells present in blood; this number does not correlate with the concentration of serum monoclonal Ig. The monoclonal blood CD19+ cells are not eliminated by any of the chemotherapy regimens analyzed and remain at high levels during transient remissions. Patients in the progressive phase of disease or in relapse have significantly higher numbers of B cells than do patients in transient remission or untreated patients. During periods when the quantity of blood B cells approaches normal, phenotypically their quality is highly abnormal, with physical and phenotypic heterogeneity. Most B cells express CD45R0, a high density of CD38, and CD56 characteristic of late-stage B or pre-plasma cells. CD38hi blood B cells had a cyclical presence. We conclude that monoclonal B cells in the blood of myeloma patient populations include drug-resistant reservoirs of clonotypic cells that may underlie relapse.

[IgD-lambda type multiple myeloma associated with IgG-kappa type benign monoclonal gammopathy].
    Nihon Rinsho Men'eki Gakkai kaishi = Japanese journal of clinical immunology, 1995, Volume: 18, Issue:2

    A 76-year-old man was admitted to Kisen hospital because of lumbago and chest pain. Laboratory examinations revealed a chronic renal failure with marked elevation of the serum BUN (48.8 mg/dl) and creatinine levels (8.2 mg/dl). The serum electrophoresis demonstrated a hypergammaglobulinemia with M peaks. An immunoelectrophoresis demonstrated monoclonal IgD-lambda and IgG-kappa proteins in the serum, and lambda-type Bence Jones protein in the urine (0.4 g/day). Bone marrow smears revealed an abnormal proliferation of atypical plasma cells (43%). A systemic X-ray examination of the skeletal system showed systemic osteoporosis without punched out lesion. The patient was diagnosed as having IgD-lambda type multiple myeloma and IgG-kappa type benign monoclonal gammopathy by quantifying concentration of two M proteins (1,160 mg/dl in IgD, 1,179 mg/dl in IgG, respectively). A combination chemotherapy with melphalan and prednisolone was administered monthly for multiple myeloma, and hemodialysis for the renal failure was performed 3 times a week. A marked improvement of his laboratory findings including a diminution of the serum IgD-lambda M-protein was obtained. On the other hand, IgG-kappa M-protein level was unchanged. Two M-protein levels showed a different behavior after the combination chemotherapy. Although the patient died of congestive heart failure, the partial remission of multiple myeloma has been maintained for 16 months with chemotherapy.

    A 67-year-old woman was treated with MP-P therapy and combination chemotherapy for multiple myeloma IgG-lambda type. After the therapy for about three years, pancytopenia developed. Bone marrow aspiration study revealed a few of myeloma cell and many atypical cells showing promyelocytic feature. Chromosomal abnormality was 46, X, -X, +8, -13, +mar. CD33 and CD56 were positive, but CD16 and HLA-DR were negative. We diagnosed as multiple myeloma complicated with secondary myeloid/natural killer (NK) cell acute leukemia. After she had been treated with low dose etoposide for leukemia, she obtained complete remission. But since myeloma progressed and the amount of M protein was increased, she was treated with dexamethasone and low dose etoposide, resulting in a decrease in the amount of M protein. After that, because of leukemic cell re-proliferation, she was treated with etoposide. However, she died of sepsis due to severe myelosuppression. This case was interesting one in coexist of multiple myeloma and secondary myeloid/NK cell acute leukemia, and those affecting her clinical course each other.

Extramedullary plasmacytomas presenting as mediastinal masses: clinicopathologic study of two cases preceding the onset of multiple myeloma.
    Modern pathology : an official journal of the United States and Canadian Academy of Pathology, Inc, 1995, Volume: 8, Issue:3

    We present two cases of extramedullary plasmacytoma presenting as a mediastinal mass and preceding the onset of full-blown multiple myeloma. The patients are a 62-year-old woman who presented with progressive dyspnea and left-sided chest pain and a 59-year-old asymptomatic man. In both patients, radiographic studies revealed a posterior and anterior mediastinal mass, respectively. Surgical resection of the tumor was performed in the two cases. The tumors were characterized by a well-circumscribed proliferation of plasma cells surrounded by residual lymph nodal tissue. Immunohistochemical studies on paraffin sections demonstrated lambda light chain restriction. Follow-up in our patients revealed that both of them developed multiple myeloma after 6 months and 2 years, respectively. One patient received treatment with melphalan and prednisone and is currently alive and well without evidence of disease, 2 years after diagnosis. The second patient died 4 years after resection of his tumor with evidence of disease in lumbar spine, skull, and lungs. Extramedullary plasmacytoma presenting as a mediastinal mass may precede the onset of full-blown multiple myeloma; therefore, institution of early systemic therapy in these patients may be of value in preventing further progression of the disease.

Myeloma during a decade: clinical experience in a single centre.
    Annals of oncology : official journal of the European Society for Medical Oncology, 1995, Volume: 6, Issue:1

    One hundred and fifty-six patients with multiple myeloma were treated over a period of 12 years at St. Bartholomew's Hospital. The progress of the disease was affected in 96/156 patients (61%). Response was defined as achieving a plateau of M component. A partial or complete response was seen in 68/120 patients treated conventionally (56.5%), and in 28/36 patients treated with high-dose therapy (77.7%). The median survival of the group as a whole was 20 months, with a 2-year survival of just over 40%. In the 36 patients treated with high-dose therapy, median survival was 6 years, and in a small group who have had maintenance Interferon therapy, the median has not yet been reached. In a univariate analysis, age, intensity of therapy, haemoglobin and creatinine levels were significant, but multivariate analysis showed that only age and intensity of therapy were independent predictors for survival. The outlook for relapsed patients who showed progression of disease remains poor, but palliation was best achieved by steroid and Interferon in combination. Patients who achieve complete responses and are maintained on Interferon appear to be doing better both in terms of freedom from symptoms and in survival, and methods to enable an elderly population to tolerate this form of therapy need to be explored.

    Acta radiologica (Stockholm, Sweden : 1987), 1995, Volume: 36, Issue:1

    The bone marrow of the spine, pelvis and proximal femora was examined with MR imaging at diagnosis in 30 cases of multiple myeloma (MM), and during treatment on 69 occasions. The MR pattern was normal, focal or diffuse and correlated to stage. A tumour mass index (TMI) was calculated by estimating the total myeloma mass visualised at MR imaging. The TMI correlated significantly with stage, lytic bone lesions, serum calcium, serum beta-2-microglobulin and survival. No abnormalities were seen at MR investigation in 4 of 6 patients classified as stage II because of osteoporosis only. Therapy efficacy evaluation with MR imaging corresponded to clinical evaluation on 54 of the 69 occasions. MR examination of bone marrow in MM patients can be used for tumour mass assessment, both at diagnosis and during follow-up. Valuable information can be obtained when the tumour mass is difficult to estimate using clinical criteria, e.g. in non-secretory MM or when osteoporosis is the only variable indicating an increase in the tumour mass.

Refractory and relapsing multiple myeloma treated by blood stem cell transplantation.
    The American journal of the medical sciences, 1995, Volume: 309, Issue:3

    Between June 1989 and June 1992, 12 patients with advanced multiple myeloma underwent peripheral blood stem cell autotransplantation after high-dose chemotherapy and radiotherapy. The conditioning regimen included melphalan (140 mg/m2), high-dose cyclophosphamide (120 mg/kg), methylprednisolone (2 g daily x 7), and total body irradiation (9-12 Gy). Transplant morbidity included severe mucositis (n = 7) and acute renal failure (n = 2) related to infusion of the stem cells. Engraftment was delayed (n = 4) in this heavily pretreated population, and two patients had complete graft failure. Despite the advanced nature and chemotherapy-refractory state of their disease, 11 of 11 evaluable patients achieved an objective response. Six patients survived to leave the hospital, and four remain alive--one died of acute leukemia induced by prior melphalan exposure. Three of the four are relapse-free at a median of 24.9 months (range, 18-28 months). Some patients with advanced refractory multiple myeloma can achieve objective responses from highdose chemoradiotherapy with peripheral blood stem cell rescue. Harvesting peripheral blood stem cells from high-risk patients early in their disease for later use may decrease the risk of graft failure. Peripheral blood stem cell transplantation after high-dose chemotherapy and total body irradiation can produce durable responses in patients with advanced refractory myeloma.

Diffuse plane xanthomatosis and acquired palmoplantar keratoderma in association with myeloma.
    The British journal of dermatology, 1995, Volume: 132, Issue:2

    We report a patient with diffuse plane xanthomatosis, acquired palmoplantar keratoderma, and myeloma. Although diffuse plane xanthomatosis is a recognized manifestation of paraproteinaemia, keratoderma is not. However, successful treatment of the myeloma in our patient coincided with a dramatic improvement in the keratoderma, suggesting a genuine association between the two disorders.

2',5'-Oligoadenylate synthetase levels in patients with multiple myeloma receiving maintenance therapy with interferon alpha 2b do not correlate with clinical response.
    British journal of cancer, 1995, Volume: 72, Issue:6

    In clinical trials with interferon alpha 2b (IFN-alpha 2b) as maintenance therapy for multiple myeloma, the therapeutic benefit is inconclusive. Although the mechanism(s) by which IFN-alpha 2b prolongs remission in some patients is unknown, 2',5'-oligoadenylate synthetase (2,5-A synthetase) has been used as an objective indicator that IFN-alpha 2b is active in vivo. The enzyme was assayed in cytosol preparations of peripheral blood mononuclear cells (MNCs) from 111 patients who were receiving IFN-alpha 2b and 54 patients who were not, using an assay which measures the conversion of [alpha-32P]ATP to triphospho(adenylyl 2',5')adenosine. 2,5-A synthetase activity was compared with response to intensive therapy and with duration of maintenance therapy. Seventy-three per cent of patients had measurable amounts of 2,5-A synthetase during the first 6 months of maintenance therapy. This percentage decreased with longer follow-up but not significantly. There was no difference between the magnitude of enzyme induction amongst patients who were in complete remission, partial response or who had no change in disease status following intensive therapy. Peripheral blood T cells were a major source of 2,5-A synthetase activity in patients receiving the cytokine. However, both T and B cells produced the enzyme following exposure to IFN-alpha in vitro. The data show that the level of 2,5-A synthetase in patients with multiple myeloma is not indicative of clinical response to IFN-alpha 2b.

Busulfan and melphalan as conditioning regimen for autologous peripheral blood stem cell transplantation in multiple myeloma.
    British journal of haematology, 1995, Volume: 91, Issue:2

    Twenty-four patients with multiple myeloma (MM), three (12.5%) in complete remission (CR) and 21 (87.5%) in partial remission (PR) were treated with high-dose chemotherapy (HDCT) (busulfan 12 mg/kg+melphalan 140 mg/m2) as preparative regimen for autologous peripheral blood stem cell (PBSC) transplantation. These cells were previously collected by leukapheresis after mobilization by high-dose cyclophosphamide (HD Cy)+rhGM-CSF (18 patients) or rhG-CSF alone (six patients). Considering 23 evaluable patients following HDCT, the CR rate was 58% (14 patients) and the PR rate was 38% (nine patients). One transplant-related death occurred following this regimen (4%). With a median follow-up of 20 months (range 4-34) after transplantation, 21 patients are alive (87%). Disease progression after transplantation was observed in four patients. Overall and relapse-free actuarial survival at 24 months was 91% and 74%, respectively. 12 patients (50%) remain in CR 15 months (4-34) post transplant. The major toxicity was mucositis. Busulfan+melphalan is a safe and feasible conditioning regimen for APBSCT in MM with acceptable toxicity and a high objective response rate, which may result in prolonged survival.

Chemotherapy-associated changes in 31P MRS spectra of sera from patients with multiple myeloma.
    NMR in biomedicine, 1995, Volume: 8, Issue:3

    31P NMR spectra were obtained from sera of 22 healthy volunteers and 20 patients with multiple myeloma at the time of diagnosis and repeated up to five times during therapy. All spectra consisted of a Pi peak (used as a reference peak) and two peaks from phospholipids (PL): one peak due to phosphatidylethanolamine and sphingomyelin (PE + SM) and a second peak due to phosphatidylcholine (PC). Prior to therapy, peak intensities of the phospholipids were low relative to Pi. During therapy leading to remission, the resonance from PL progressively increased to approximate the spectral pattern seen in normal sera. By contrast, in non-responders an opposite trend was noted: the intensities of the phospholipid peaks became progressively reduced or remained unchanged. Long-term follow-up studies showed a good correlation between this 31P MRS evaluation of sera and the response of the disease to the therapy. In addition to the correlation with tumor response, our studies also show significant correlations between area, intensities of peaks of PE + SM, PC, and the concentrations of high-density lipoprotein (HDL) (correlation coefficients 0.46, 0.43, 0.59, respectively; p < 0.001). We found that the concentration of HDL in serum of patients with multiple myeloma was significantly reduced. In individuals responding to therapy HDL levels increased to the point where there were no statistically significant differences between them and healthy volunteers. In patients not responding to therapy, HDL concentration did not increase.(ABSTRACT TRUNCATED AT 250 WORDS)

Up-regulation of gamma-glutamylcysteine synthetase activity in melphalan-resistant human multiple myeloma cells expressing increased glutathione levels.
    Cancer chemotherapy and pharmacology, 1994, Volume: 34, Issue:1

    Levels of intracellular glutathione (GSH) and the GSH-related enzymes gamma-glutamylcysteine synthetase (gamma-GCS) and gamma-glutamyltranspeptidase (gamma-GT) were measured in the melphalan-resistant human multiple myeloma cell line 8226/LR-5 and were compared to those measured in the drug-sensitive 8226/S and doxorubicin-resistant 8226/Dox40 cell lines. Both GSH and gamma-GCS activity, the rate-limiting step in the de novo synthesis of GSH, were elevated by a factor of approximately 2 in the melphalan-resistant 8226/LR-5 cells relative to the other two lines. gamma-GT activity was not elevated significantly in the /LR-5 cells. Northern analysis with a probe specific for the large subunit of human liver gamma-GCS identified two bands (3.2 and 4.0 kb), both of which were increased by a factor of 2-3 in the 8226/LR-5 line. Levels of gamma-GCS mRNA expression were comparable in the /S and /Dox40 cell lines. Levels of gamma-GT mRNA were similar in the /S and /LR-5 lines but were reduced in the /Dox40 cells. These data suggest that the increased GSH levels associated with resistance to melphalan in the 8226/LR-5 myeloma cells is attributable to up-regulation of gamma-GCS. This observation is consistent with recent demonstrations of up-regulation of gamma-GCS in melphalan-resistant prostate carcinoma cells and cisplatinum-resistant ovarian carcinoma cells, suggesting that increased expression of gamma-GCS may be an important mediator of GSH-associated resistance mechanisms.

The costs of peripheral blood progenitor cell reinfusion mobilised by granulocyte colony-stimulating factor following high dose melphalan as compared with conventional therapy in multiple myeloma.
    European journal of cancer (Oxford, England : 1990), 1994, Volume: 30A, Issue:4

    In a retrospective study, we calculated the treatment costs of 26 patients, who received either high dose melphalan combined with granulocyte colony-stimulating factor (G-CSF; filgrastim)(n = 7) or without G-CSF (n = 11) or alternatively, peripheral blood progenitor cell reinfusion (PBPC) mobilised by G-CSF following high dose melphalan. In comparison with the control group, a shortening of the pancytopenic period and platelet recovery was noticed in the PBPC group. This resulted in a reduction in hospital costs, diagnostics, laboratory services, total parenteral nutrition and transfusions. The average costs per treatment in the PBPC group amounted to about US$ 17,908 as compared to US$ 32,223 in the control group, implying a cost reduction of 44% when changing to PBPC reinfusion.

Peripheral blood progenitors mobilised by G-CSF (filgrastim) and reinfused as unprocessed autologous whole blood shorten the pancytopenic period following high-dose melphalan in multiple myeloma.
    Bone marrow transplantation, 1994, Volume: 13, Issue:1

    Growth factor granulocyte colony-stimulating factor (G-CSF; filgrastim) is effective at progenitor release into the peripheral blood. After high-dose chemotherapy haematopoietic reconstitution occurs after reinfusion of these peripheral blood progenitor cells (PBPC). However, the collection by leukapheresis and further processing of PBPC are very time consuming and expensive. We have studied the transplantation potential of a small volume of unprocessed autologous whole blood after G-CSF mobilisation. Six patients with plasma cell disorders received G-CSF 10 micrograms/kg sc during 6 days. Subsequently 11 of whole blood was collected by phlebotomy, kept unprocessed at room temperature and reinfused 24 h after high-dose melphalan 140 mg/m2. CFU-GM content was 845 per ml blood (median, range 320-3472) and CD34+ cells rose to a median percentage of 0.9 (range 0.4-2.0). Haematological recovery was significantly faster in the study group compared with the control group of 20 patients who received the same dose of melphalan without reinfusion of PBPC. The neutrophil count reached 0.5 x 10(9)/l at a median of 12.5 days after infusion of PBPC vs 38 days in the control group (p = 0.0003). The platelet count reached 20 x 10(9)/l after a median of 23.5 days vs 38 days (p = 0.0218). The shortened recovery was reflected by less transfusions, less antibiotic use and shortening of hospital stay (19 days vs 43 days, p = 0.0003). We conclude that this easy technique of mobilisation and collection of PBPC is very effective for hastening haematologic recovery after high-dose chemotherapy.

Autologous bone marrow transplantation for myeloma patients using PNA- and CD19-purged marrow rescue.
    Bone marrow transplantation, 1994, Volume: 13, Issue:6

    A new method of in vitro bone marrow purging using a lectin and monoclonal antibody in combination has been used for the first time in vivo. Two patients with advanced myeloma were treated with high-dose melphalan and total body irradiation and then rescued with autologous bone marrow which had been purged in vitro to remove malignant cells by using a combination of a plasma cell-binding lectin (peanut agglutinin, PNA) and the anti-B lymphocyte monoclonal antibody anti-CD19, bound to magnetised microspheres. Both patients showed rapid engraftment of the purged bone marrow and remain well 36 and 46 months later with normal bone marrow morphology, although one patient still has a low level of circulating paraprotein. This is a promising form of therapy for what has been an invariably fatal condition.

[Multiple myeloma preceding myelodysplastic syndrome with eosinophilia and der (1;7)].
    [Rinsho ketsueki] The Japanese journal of clinical hematology, 1994, Volume: 35, Issue:11

    Multiple myeloma (IgG kappa + IgA kappa type, clinical stage IA) was diagnosed in a 82-year-old woman in January 1986. Chemotherapy (melphalan, prednisolone, vindesine, cyclophosphamide), caused prolonged myelosuppression. Therefore she was given other treatment. In October 1992, her peripheral blood examination demonstrated 2% blastic cells and 12% eosinophils. Bone marrow aspiration showed dysplastic features of trilineage blood cells with 4.8% myeloblasts. The karyotype of bone marrow cells from this patients was 47, XX, +der(1)t(1;7) (p11;p11), -7, +8. A diagnosis of therapy-related myelodysplastic syndrome (refractory anemia) was established. Eleven months after diagnosis of myelodysplastic syndrome, she is alive without leukemic transformation.

Secondary myelodysplastic syndrome in multiple myeloma--a study of nine patients with an attempt to detect myeloma patients at risk.
    Haematologia, 1994, Volume: 26, Issue:2

    Over a follow-up period of ten years, nine of our 100 patients with multiple myeloma (MM), developed myelodysplastic syndrome (MDS, preleukaemia). MDS occurred 19-156 (median 35) months from the diagnosis of MM. Six patients presented with pancytopenia and no patients had active MM at the time of MDS diagnosis. Three patients were defined as having refractory anaemia (RA) and six as refractory anaemia with excess blasts (RAEB) or RAEB in transformation (RAEBT), according to the FAB classification. The clinical course is characterized by increasing red blood cell and platelet transfusion requirements, recurrent infections and bleeding episodes. All patients, except for one, died within 3 to 8 (median 5) months from MDS diagnosis. The causes of death were sepsis or bleeding; three patients underwent leukaemic transformation. Thus, the clinical course of this small group of myeloma patients who developed secondary MDS (sMDS), was similar to other series of patients with sMDS. Serial bone marrow examinations suggest an initial hypercellular phase, followed by a rapidly evolving preterminal hypocellular marrow. In an attempt to detect MM patients at risk of developing sMDS, the epidemiological (including ethnic), clinical and laboratory data of the 9 MDS patients at the time of the MM presentation were reviewed and compared to the other MM patients. No significant differences were observed between the two groups in most parameters, except for two. All MDS patients were Ashkenazi Jews and no patients of Sepharadic origin developed MDS. Also, no IgA-myeloma patient developed MDS. If these findings are confirmed in a larger series, it may point to subgroups at risk which may require a different approach.(ABSTRACT TRUNCATED AT 250 WORDS)

    Within a period from March 1983 to November 1988, 93 newly diagnosed patients with multiple myeloma, 47 men and 46 women aged from 41 to 80 years were treated with protocol VBCMP-M2. A response was achieved in 30 (60%) patients in stage II and 22 (51%) in stage III, the overall response rate being 56%. 41% of all patients entered plateau phase, more frequently in stage II (46%) than in stage III (37%) patients. The median survival of all patients was 35 months. Comparing these groups of patients with other series from the literature, we were not able to demonstrate any advantage of this multidrug combination over other combinations or even melphalan and prednisone alone.

    A 35-year-old male presented with chronic myelomonocytic leukemia (CMMoL) after 6.5 years of alkylating agent therapy for IgG-kappa type multiple myeloma. The total dose of melphalan was 0.648 g. CMMoL was stable with weekly injection of alpha-interferon for one year. Thereafter, monocytosis and thrombocytopenia aggravated, and the patient died of disseminating intravascular coagulation. Prolonged drug therapy can induce CMMoL, as well as other myelodysplastic syndromes.

Multiple myeloma: the National University Hospital (NUH) experience.
    Singapore medical journal, 1994, Volume: 35, Issue:4

    The aim of this retrospective study was to define the characteristics of local patients with multiple myeloma. Twenty-nine de novo cases were accrued from October 1986 to January 1992 at the National University Hospital of Singapore. Features like median age of presentation, sex distribution, the incidence of IgG, IgA and light chain subtypes were similar to published data. However IgD myeloma appeared to be more common here and it tended to be more advanced at presentation. Objective response rate to treatment with the melphalan-prednisolone combination was about 40% with a median survival of 18 months.

High-dose therapy for refractory multiple myeloma: improved prognosis with better supportive care and double transplants.
    Blood, 1994, Aug-01, Volume: 84, Issue:3

    One hundred and thirty-five patients with advanced and refractory myeloma received one of three high-dose therapy regimens: melphalan at doses of 90 to 100 mg/m2 (MEL 100; 47 patients) without autotransplant; total body irradiation (TBI; 850 cGy) with either melphalan 140 mg/m2 or thiotepa 750 mg/m2 and autologous bone marrow transplant (ABMT) (< or = 30% plasma cells; 21 patients); melphalan 200 mg/m2 (MEL 200) supported by both peripheral blood stem cells (PBSC) and ABMT plus GM-CSF intended as a double-transplant program (67 patients; 42 have completed and 3 are still awaiting a second autotransplant; 5 additional patients received an allograft for their second transplant). Mortality within 2 months of therapy was 20% to 25% with MEL 100 and TBI regimens, but less than 1% with MEL 200, mainly because severe neutropenia (< 500/microL) was shortened to less than 1 week due to infusion of PBSC and use of growth factor therapy. Low beta 2-microglobulin (beta 2M) levels < or = 2.5 mg/L and MEL 200 therapy were identified as the two most important independent favorable variables associated with prolonged event-free survival (EFS) and overall survival (OS). On the basis of these two parameters, three risk groups were defined: 29 good-risk patients with low beta 2M receiving MEL 200 had the best outcome, with median durations of EFS of 37 months and projected OS of > or = 43 months; 54 intermediate-risk patients displaying one of the two favorable parameters had EFS and OS durations of 16 and 36 months, respectively; and 52 poor-risk patients with high beta 2M not receiving MEL 200 had a dismal prognosis, with EFS of 3 months and OS of 5 months (all P < .0001). Further analysis that excluded treatment as a variable identified high beta 2M and resistant relapse as the two major adverse prognostic factors, one of which was present in 80% of the 135 patients. Among these 108 high-risk patients, prognosis was improved markedly with MEL 200 because of both better supportive care (PBSC and hematopoietic growth factors) and more intensive therapy using the double-transplant approach. This study supports the concept that safer and potentially more-effective therapies can be developed in the setting of advanced and resistant disease.

Three courses of high dose therapy. Feasibility in the treatment of multiple myeloma--a "France autogreffe" study.
    Cancer, 1994, Dec-01, Volume: 74, Issue:11

    High dose melphalan is used widely in the treatment of multiple myeloma (MM) and in the conditioning regimen of autologous stem cell transplantation (ABST). Double courses of high dose melphalan and double autologous bone marrow transplantation (ABMT) programs also have been widely reported. However, there are no data about the feasibility and efficacy of three courses of high dose therapy, such as high dose melphalan or powerful therapies in the treatment of malignant disease.. In 1991, a retrospective study in France was initiated to evaluate how many patients with MM had received three courses of high dose therapy with or without hematopoietic stem cell rescue.. This small study of six patients with multiple myeloma showed that three courses of high dose therapy with or without stem cell rescue can be performed with relative safety. Stem cell rescue appears to shorten the duration of aplasia. In terms of antitumor response, long term response could be obtained in patients with MM that responded to the first course of high dose melphalan.. High dose therapy with or without ABMT can be an effective treatment for relapse in a subgroup of patients with MM who respond to high dose melphalan as initial treatment.

Quality and functional capacity of the bone marrow microenvironment of autologous blood stem cell transplantation (ABSCT) recipients.
    Nouvelle revue francaise d'hematologie, 1994, Volume: 36, Issue:4

    We have previously reported that the rate of haematopoietic recovery following Autologous Blood Stem Cell Transplantation (ABSCT) could be influenced by the type of conditioning regimen or by the underlying disease. Furthermore, Peripheral Blood Stem Cell (PBSC) growth was found to be sensitive to stimulation by irradiated allogeneic stromal layers. In the present study, we used the long term culture system (LTC) to investigate the quality of the bone marrow (BM) microenvironment from patients who had undergone ABSCT for either Malignant Lymphoma (ML, 13 patients) or Multiple Myeloma (MM, 8 patients) after conditioning regimens comporting myeloablative chemotherapy (CT) or Total Body Irradiation (TBI). Among the 13 ML patients, 10 received CT conditioning and 9 of the 10 BM samples developed a complete confluent stromal layer. The remaining 3 ML patients received TBI prior to ABSCT and 2 of the 3 samples developed confluent stroma. In contrast, when LTC were established with BM from the 8 MM patients, all of whom were treated with TBI prior to ABSCT, only 3 of the 8 marrow samples developed a complete confluent stromal layer. Thus BM from patients who had received CT conditioning therapy tended to form confluent stroma more often than BM from those who had received TBI (p = 0.08). CFU-GM production was also evaluated for the stromal layers derived from all transplanted patients.(ABSTRACT TRUNCATED AT 250 WORDS)

High-dose intravenous melphalan in a patient with multiple myeloma and oliguric renal failure.
    The Clinical investigator, 1994, Volume: 72, Issue:7

    A kappa light-chain myeloma was diagnosed as the underlying disease in a 52-year-old woman with acute oliguric renal failure. The patient was erroneously treated with high-dose intravenous melphalan (60 mg/m2). Because of this overdose treatment with granulocyte colony-stimulating factor was initiated, but pronounced absolute leukopenia (white blood cell count < 0.5 x 10(9)/l) developed and lasted for 13 days. Following melphalan treatment a continuous increase in urine volume was accompanied by a decrease of serum creatinine and blood urea nitrogen. Within 10 days after the administration of melphalan the patient no longer required hemodialysis. We conclude that high-dose chemotherapy in combination with hematopoietic growth factors should be considered in individual cases with newly diagnosed light-chain nephropathy.

Early myeloablative therapy for multiple myeloma.
    Blood, 1994, Dec-15, Volume: 84, Issue:12

    The value of early myeloablative therapy supported by autologous bone marrow or blood progenitor cells was assessed in 72 patients with multiple myeloma who were treated within 1 year of initial therapy. Forty-five patients were consolidated during remission, and 27 patients were treated for primary refractory disease. Outcomes were compared with those of similar patients who did not receive intensive treatment primarily for socioeconomic reasons. Among patients who had responded previously, myeloablative therapy increased the rate of complete remission from 5% to 45% (P < .01) but did not prolong progression-free intervals or survival times. The same treatment controlled the myeloma in 70% of patients with primary resistant disease and prolonged the median survival from 37 to 83 months (P = .03). Intensive treatment for primary resistant myeloma administered later in the disease course resulted in significantly lower response rates and shorter progression-free intervals. Current myeloablative regimens supported by autologous stem cells appeared useful primarily in patients with primary resistant disease during the first year of therapy.

The C.B.17 scid mouse strain as a model for human disseminated leukaemia and myeloma in vivo.
    Leukemia research, 1994, Volume: 18, Issue:7

    Using the C.B.17 scid mouse strain, we have developed a model of disseminated leukaemia and myeloma using five human cell lines, CCRF-Cem, Molt-4, Raji, IM9 and HS-Sultan. Introduction of any of these cell lines by either an intravenous or an intraperitoneal route eventually kills the mouse due to leukaemia or myeloma cell load. Neoplastic cells can be found in the blood, liver and bone marrow. Intraperitoneal transfer produces a local solid tumour whereas intravenous transfer produces foci of neoplastic cells in the spine and brain. A single dose of melphalan is able to increase survival time from infection of a lethal dose of the T-cell leukaemia cell line, CCRF-Cem.

Coexisting kappa light chain multiple myeloma and primary hyperparathyroidism.
    Scandinavian journal of rheumatology, 1994, Volume: 23, Issue:1

    The authors report the case of an 82 year old woman hospitalized for hypercalcemia associated with low serum phosphate. Multiple myeloma was first diagnosed. However, despite chemotherapy, hypercalcemia persisted and she was subsequently diagnosed as primary hyperparathyroidism; eucalcemic state was then obtained after parathyroidectomy. Fifteen similar cases are reported in the literature and the mechanisms and implications of such an association are discussed.

[Skin lesions as a rare initial symptom of Kahler's disease].
    Nederlands tijdschrift voor geneeskunde, 1994, Mar-05, Volume: 138, Issue:10

    Multiple skin lesions developed in a 70 year-old-man. Pathological examination revealed plasmacytomas. Because of the presence of a IgD paraprotein and 15% abnormal plasma cells in the bone marrow Kahler's disease of the IgD type was diagnosed. In accordance with literature the course of the disease was rapidly progressive. After an initial favourable response to chemotherapy and radiotherapy, the patient died one year after diagnosis. Extraosseous tissue involvement and hepatosplenomegaly are well-known phenomenon of IgD-Kahler's disease. Skin plasmacytomas as the first symptom of the disease are very rare.

High-dose melphalan for multiple myeloma: long-term follow-up data.
    Journal of clinical oncology : official journal of the American Society of Clinical Oncology, 1994, Volume: 12, Issue:4

    To present long-term follow-up data of patients with myeloma treated with high-dose melphalan HDM, including an assessment of prognostic factors.. Between November 1981 and April 1986, 63 previously untreated patients with multiple myeloma received HDM 140 mg/m2 without autologous bone marrow transplantation.. The overall response rate was 82% (51 of 62), with 32% (20 of 62) patients entering complete remission (CR). The median duration of response was 18 months, and six patients remain alive and free from disease progression at 60+ to 84+ months. Improvements in quality of life associated with remission were immediate in terms of pain grade (89% of patients) and performance status (92%), and later in terms of bone healing (29%). Currently, at a median follow-up duration of 74 months (range, 63 to 100) since HDM, 23 patients are alive with a median survival duration of 47 months, and 35% of patients are expected to be alive at 9 years. Apart from early-stage disease, no factors were found to predict long-term survival. No second malignancies or other late side effects have been recorded.. Single-agent HDM without autologous bone marrow transplantation is a feasible therapeutic option in myeloma, and is associated with a high objective response rate, relatively long remission durations, and good symptom control.

Relapse of aggressive myeloma after complete remission in secondary acute leukemia: coincidence or consequence?
    Leukemia & lymphoma, 1993, Volume: 12, Issue:1-2

    We describe a patient with multiple myeloma who developed secondary acute myelomonocytic leukemia after long-term melphalan treatment. Following two courses of low-dose cytarabine, complete remission of the A.M.L. was achieved. Shortly thereafter an aggressive relapse of the quiescent myeloma occurred with acute renal failure and massive infiltration of bone marrow with multinucleated giant plasma cells. Although it is well known that administration of melphalan to patients with multiple myeloma increases the likelihood of A.M.L., this case demonstrates that treatment of A.M.L. in a patient with multiple myeloma may perhaps influence the course of multiple myeloma.

    Revue du rhumatisme (Ed. francaise : 1993), 1993, Volume: 60, Issue:4

    Although studies of patients with rheumatoid arthritis have found no increases in overall cancer rates, significant elevations in rates of lymphoma and myeloma have been reported, suggesting a causal relationship between autoimmune disorders and lymphoid malignancies. Nevertheless, only 22 cases of concomitant rheumatoid arthritis and multiple myeloma were identified during a retrospective national multicenter study carried out in France. Neither disease exhibited unusual features. In every case, rheumatoid arthritis preceded multiple myeloma. Monoclonal gammopathy preceded multiple myeloma in two patients, by 3 and 7 years respectively. No patient had amyloid arthritis. Analysis of data from the cancer registry of the Somme district in northern France did not suggest a significantly increased risk of multiple myeloma in rheumatoid arthritis patients (relative risk 2.3). Use of interferon alpha to treat myeloma has been reported to exacerbate concomitant autoimmune disorders.

Repeat administration of high dose melphalan in relapsed myeloma.
    British journal of cancer, 1993, Volume: 68, Issue:5

    At a median time of 20 months following high dose melphalan for myeloma, 29 patients relapsed and were treated with induction chemotherapy to maximum response followed by a second course of high dose melphalan. The majority (90%) of patients received 200 mg m-2 with an autologous bone marrow transplant. Sixteen (55%) patients achieved complete remission and 11 (38%) a partial response. The median duration of remission was 17 (4-42) months. The median survival has not been reached, with 50% of patients alive at 58+ months after presentation. The period of neutropenia was similar during both first and second high dose procedures, but the duration of thrombocytopenia was longer in patients receiving melphalan for a second time (median 22 (16-56) days and 41 (18-69) days respectively). There was one treatment-related death due to thrombocytopenic haemorrhage. Repeated administration of high dose melphalan is a feasible approach for patients with relapsed myeloma.

Therapy-related myelodysplastic syndrome. Two cytogenetically unrelated abnormal clones in a patient with multiple myeloma.
    Cancer genetics and cytogenetics, 1993, Oct-15, Volume: 70, Issue:2

    A multiple myeloma patient presented for cytogenetic analysis at diagnosis of secondary MDS, which followed cytotoxic treatment including melphalan. Two abnormal unrelated clones were detected, one of them had 5q-, 7q- with clonal evolution of an additional aberration, t(12;13); in the second clone there was a translocation between the two homologues of chromosome 1 as the only aberration. We suggest that the clone with 5q- and 7q- represented the secondary MDS cells, whereas the abnormal clone with t(1;1) represented the plasmablasts of the multiple myeloma.

Prognostic value of plasma-cell immunophenotype in patients with multiple myeloma.
    Neoplasma, 1993, Volume: 40, Issue:6

    A review is given of the prognostic significance of immunophenotyping of blood lymphoplasmocytic cells. From a group of 250 patients followed from 1981 through 1991 a subgroup of 70 patients (followed 1986 through 1991) were phenotyped at 6-month intervals by immunofluorescence tests with monoclonal antibodies for cytoplasmic immunoglobulin, kappa-lambda index, CD71, CD10, CD20, CD38, and HLA-DR receptors. In course of a longitudinal study it was found that prognostic significance for shortened survival can be derived from the presence of circulating CD10, CD71, and CD20 positive undifferentiated cells in peripheral blood. There was a correlation between increase of CALLA positive and CD71 positive cells. Further, an increase of undifferentiated clone occurred during transition of the disease to an aggressive phase. The median survival of the total group of 250 patients treated by the VMCP/MOCCA protocol, according to statistical analysis, was 90 months, the median survival of the aggressive stage with plasmoblastic and lymphoplasmocytic cell type, respectively, was only 12 months. The significance of phenotypization in the prognostic evaluation of variant heterogenous myeloma types is stressed.

Radiopharmaceutical therapy of 5T33 murine myeloma by sequential treatment with samarium-153 ethylenediaminetetramethylene phosphonate, melphalan, and bone marrow transplantation.
    Journal of the National Cancer Institute, 1993, Sep-15, Volume: 85, Issue:18

    Total-body irradiation, followed by hematopoietic system rescue by bone marrow transplantation (BMT), has been found to improve the response of patients with multiple myeloma to treatment with melphalan. The problems of nonhematopoietic toxicity from whole-body irradiation might be circumvented by using a bone-seeking radiopharmaceutical, such as samarium-153 ethylenediaminetetramethylene phosphonate (153Sm-EDTMP), to ablate the bone marrow.. A mouse model system for multiple myeloma was used to evaluate the potential therapeutic efficacy of sequential therapy with 153Sm-EDTMP, melphalan, and BMT.. Female C57BL/KaLwRij mice were inoculated with 8 x 10(5) 5T33 murine myeloma cells. Treatment protocols were begun 3 or 10 days later, when the myeloma was either confined to bone marrow or disseminated in liver, spleen, and lymph nodes, simulating human multiple myeloma. 153Sm, a potent beta particle-emitting radioisotope of short half-life (46.7 hours), was linked to the bone-seeking chelate EDTMP. Animals in the first treatment group were each given 22.5 MBq 153Sm-EDTMP via the jugular vein (day 3 or 10), followed by 18.5 mg/kg melphalan (maximum tolerated dose) given intraperitoneally 5 days later (day 8 or 15) and syngeneic BMT another 2 days later (day 10 or 17). Survival in groups of six to 10 animals for each time series was compared with that in mice left untreated (control cohort), in mice treated with 153Sm-EDTMP alone (day 3 or 10), or in mice treated with melphalan alone (day 8 or 15). The hematopoietic systems of animals in the latter two treatment groups recovered full function, obviating the necessity of BMT. The end point was onset of paraparesis, at which time the animals were immediately killed by carbon dioxide asphyxiation.. Median survival in untreated control animals was 23 days in those with localized disease and 24 days in those with disseminated myeloma. Treatment with 153Sm-EDTMP alone improved survival to a median of 29 days when commenced on day 3 and 30 days when begun on day 10. Melphalan treatment alone improved the median survival to 31 days for animals with localized myeloma and 34 days in animals with disseminated disease. Additional improvement in survival to a median of 42 days was achieved in animals treated 3 days after tumor inoculation with sequential 153Sm-EDTMP, melphalan, and BMT; median survival was 40 days using this regimen in animals with disseminated myeloma.. Animals in all three treatment protocols survived longer than those left untreated after inoculation with myeloma cells (P < .001). Sequential treatment with 153Sm-EDTMP, melphalan, and BMT was significantly more effective than single-agent treatment (P < .01). No evidence of radiotoxicity was detected in nonhematopoietic organs.. The survival advantage conferred by our sequential treatment protocol suggests its potential clinical usefulness in the treatment of multiple myeloma and other hematologic malignancies in humans.

Combination therapy with interferon-dexamethasone for newly diagnosed patients with multiple myeloma.
    Cancer, 1993, Nov-01, Volume: 72, Issue:9

    Alpha-interferon and dexamethasone are each effective in patients with multiple myeloma and have a combined inhibitory effect on the in vitro growth of myeloma colonies. The effect of combined therapy in newly diagnosed patients is unknown.. Fifty-one consecutive patients with previously untreated multiple myeloma of low tumor mass received primary therapy with 3 million units (mu)/m2/day of interferon administered subcutaneously for 20 days and 20 mg/m2 of dexamethasone given orally each morning for 4 days beginning on days 1, 9, and 17. Courses were repeated after a rest period of 14 days. Results were compared with those of similar patients who received primary treatment with dexamethasone alone in the same dose regimen.. The response rate was similar: 57% for patients treated with interferon-dexamethasone and 48% for those treated with dexamethasone alone. Remission and survival times of both groups were identical. Twenty-nine percent of patients resistant to interferon-dexamethasone and 19% of patients resistant to dexamethasone responded subsequently to either standard melphalan-prednisone or to a cyclophosphamide-vincristine-doxorubicin-dexamethasone combination. These regimens were also effective in one third of patients with disease relapse despite interferon.. In this nonrandomized study of previously untreated patients with multiple myeloma, the addition of interferon in a dose of 3 mu/m2/day to dexamethasone achieved results similar to those with dexamethasone alone.

Renal replacement therapy in multiple myeloma and systemic amyloidosis.
    Irish journal of medical science, 1993, Volume: 162, Issue:6

    Renal failure frequently complicates both multiple myeloma and systemic amyloidosis. Renal replacement therapy (RRT) may be poorly tolerated and its role in such patients is not clearly defined. Of fifty patients (26 males and 24 females) referred to a single centre because of renal failure associated with multiple myeloma or systemic amyloidosis 37 progressed to end-stage renal failure and 30 of these patients received RRT. Nine patients have been treated by CAPD, 13 by haemodialysis, and 8 patients have required both forms of dialysis. Overall one year and two year survival rates were 66% and 57% respectively. The median duration on RRT was 7.5 months (range 1-96 months) with a 51% one year, and a 46% two year survival rate. Of 7 patients with amyloidosis who underwent renal transplantation, 3 died within 6 months of transplantation. Undiagnosed cardiac involvement contributed to this early mortality. We conclude that renal replacement therapy is appropriate for some patients with multiple myeloma and systemic amyloidosis who develop endstage renal failure. Careful assessment and selection of patients is necessary prior to renal transplantation.

[Smoldering myeloma].
    Orvosi hetilap, 1993, Sep-26, Volume: 134, Issue:39

    The authors present the history of a 74 year old woman. The patient was observed from 1972. Initially the bone marrow and serum protein dischanges were identical to multiple myeloma, therefore she was treated with melphalan-prednisolone regimen for one year. She was symptom free for 12 years with none of any treatment. Her bone marrow picture and serum protein aberrations were stabil. In 1985, the clinical signs and laboratory parameters of multiple myeloma arised. Major clinical symptoms, myelomatous bone lesions were detectable and the monoclonal protein level increased. In activation period repeated local irradiation and VCMP and VACP polychemotherapy was performed. Her history was typical to smoldering myeloma. The presentation of that disease is not available in Hungarian literature. The authors present the criteria of diagnosis, the therapeutic possibilities and the differential diagnosis of benign and malignant gammopathies.

Pharmacokinetics of peptichemio in myeloma patients: release of m-L-sarcolysin in vivo and in vitro.
    Cancer chemotherapy and pharmacology, 1993, Volume: 31, Issue:4

    Peptichemio (PTC) is a mixture of six synthetic oligopeptides, each of which contains the alkylating residue m-[di(2-chloroethyl)amino]-L-phenylalanine (L-mSL). The fate of PTC was investigated in eight patients with multiple myeloma after intravenous infusion of the drug. The quantitative analysis of the plasma samples was performed by liquid chromatography with fluorometric detection. L-mSL was rapidly released from the peptides and reached its maximal plasma concentration at the end of the infusion. Its median elimination half-life was 1.73 (range, 0.72-2.41) h. It was possible to follow the concentration of only one of the peptides, L-mSL-L-Arg(NO2)-L-Nval.OEt, during and shortly after the infusion of PTC. The stability of L-mSL and the peptides was studied in buffer solution (pH 7.3), plasma, and blood. The stability of some of the peptides was drastically decreased in blood, the degradation half-lives being only about 1 min. We conclude that L-mSL plays an important role in the mechanism of action of PTC.

IgE response in multiple myeloma.
    Annals of allergy, 1993, Volume: 70, Issue:3

    IgE levels in sera of patients with multiple myeloma (MM) were found to be similar to those of patients with monoclonal gammopathy of unknown significance (MGUS) and to normal controls. This is in contrast to the significant depression in the level of the other polyclonal isotypes in patients with MM. Immediate skin test response to common environmental allergens was also preserved in patients with MM as compared with normal nonatopic controls. One-year treatment of MM patients with alkylating agents caused a significant decrease in the monoclonal immunoglobulin level and induced a tendency toward decreasing IgE level but had no effect on the polyclonal immunoglobulin concentrations. These findings suggest that IgE production and immediate skin test response is not impaired by the pathologic process in MM patients, in contrast to the production of other polyclonal immunoglobulins. This demonstrates the dissociation between the response of the IgE antibody and the other isotypes.

Alteration of the systemic antitumor activity of melphalan by sodium cyanate in MOPC-460D myeloma-bearing BALB/c mice.
    Journal of surgical oncology, 1993, Volume: 52, Issue:2

    Sodium cyanate is a selective inhibitor of protein synthesis in a variety of mammalian tumor cells without a corresponding effect on normal tissue of the tumor-bearing animals. In the present study, we investigated the potential role of sodium cyanate in the augmentation of the antitumor activity of melphalan in MOPC-460D myeloma-bearing BALB/c mice. The simultaneous intraperitoneal injection of sodium cyanate, 250 mg/kg, and melphalan, 12 mg/kg, followed by another dose of sodium cyanate, 200 mg/kg, administered 18 hours later, resulted in a tumor growth inhibition index (TGII) of 207%. In contrast, melphalan or sodium cyanate administered separately at the same dose induced a TGII of 133% and 15%, respectively, when compared to control animals. Furthermore, a direct comparison of the volume of tumor implants in mice treated with the combination of sodium cyanate and melphalan vs. those treated with melphalan alone showed a statistically significant growth inhibition in favor of the sodium cyanate and melphalan combination on days 35, 39, and 42 from initiation of treatment. The data presented here suggest that the antitumor activity of melphalan could be increased, with moderate toxicity, by the concomitant intraperitoneal administration of sodium cyanate in BALB/c mice bearing measurable subcutaneous MOPC-460D tumor transplants. This is the first report of an increase in melphalan antitumor activity by sodium cyanate at a tumor location distant from the site of injection.

Application of a sensitive immunoassay to the study of DNA adducts formed in peripheral blood mononuclear cells of patients undergoing high-dose melphalan therapy.
    European journal of cancer (Oxford, England : 1990), 1993, Volume: 29A, Issue:5

    The levels of DNA adducts formed in peripheral blood mononuclear cells of 13 patients undergoing high-dose melphalan therapy were determined 0-24 h after drug administration using a modification of a previously described immunoassay. This assay was validated for DNA extracted from drug-treated cells. Adduct levels in normal mononuclear blood cells 1 h after drug administration correlated well (r = 0.846) with drug dose (expressed as mg/m2) and with area under the curve for plasma levels of melphalan during the first h (r = 0.842). 1 patient sustained a high degree of toxic side-effects from the melphalan treatment and showed a high level of adducts. Plasma cell leukaemia tumour cells from another patient showed a level of adducts approximately six times higher than those in the normal blood cells of the other patients. The levels of DNA adducts in normal peripheral blood mononuclear cells did not change markedly between 1 and 24 h after drug administration.

    There are only 3.3% of patients with multiple myeloma in Japan Myeloma Study Group who have lived longer than ten years. Features associated with long survival include responded well to simple treatment such as melphalan or cyclophosphamide and prednisone, short duration of treated time with long activity and prolonged unmaintained remissions. High-dose melphalan therapy, VAD chemotherapy and MCNU-VP16-melphalan combination were tried for patients relapsed with alkylating agents and the result were reported.

Double-intensive therapy in high-risk multiple myeloma.
    Blood, 1992, Jun-01, Volume: 79, Issue:11

    A high remission rate is achieved with high-dose melphalan (HDM) in multiple myeloma (MM), and autologous transplantation of hematopoietic stem cells allows a prompt hematologic recovery after high-dose therapy. We treated 97 patients with high-risk MM (group 1:44 advanced MM including 14 primary resistances and 30 relapses; group 2: 53 newly diagnosed MM) with a first course of HDM. For responding patients a second course of high-dose therapy with hematopoietic stem cell support was proposed. After the first HDM, the overall response and complete remission rates were 71% and 25% with no significant difference between the two groups. The median durations of neutropenia and thrombocytopenia were significantly longer in group 1 (29.5 days and 32 days, respectively) than in group 2 (23 days and 17 days, respectively). This severe myelosuppression led to eight toxic deaths and the fact that only 38 of the 69 responders could proceed to the second course (three allogenic and 35 autologous transplantations). Among the 35 patients undergoing autologous transplantation (10 in group 1, 25 in group 2), 31 received their marrow unpurged collected after the first HDM, and four received peripheral blood stem cells. The median durations of neutropenia and thrombocytopenia after autologous transplantation were 24 days and 49 days, respectively. Two toxic deaths and nine prolonged thrombocytopenias were observed. The median survival for the 97 patients was 24 months (17 months in group 1, 37 months in group 2) and the median duration of response was 20 months. The only parameters that have a significant impact on the survival are the age (+/- 50 years) and the response to HDM. The median survival of the 35 patients undergoing autologous transplantation is 41 months, but the median duration of remission is 28 months with no plateau of the remission duration curve. Patients responding to HDM may have prolonged survival, but even a second course of high-dose therapy probably cannot eradicate the malignant clone.

Low-risk intensive therapy for multiple myeloma with combined autologous bone marrow and blood stem cell support.
    Blood, 1992, Oct-01, Volume: 80, Issue:7

    To improve the safety of autotransplantation for myeloma, peripheral blood stem cell (PBSC) collection was attempted in 75 previously treated patients after the administration of high-dose cyclophosphamide (HD-CTX; 6 g/m2) with or without granulocyte-macrophage colony-stimulating factor (GM-CSF). Sixty patients subsequently received melphalan 200 mg/m2 (57 patients) or melphalan 140 mg/m2 and total body irradiation (850 cGy) (3 patients) supported by both autologous bone marrow and PBSC; 38 patients received GM-CSF posttransplantation. Among 72 patients undergoing PBSC apheresis, "good" mobilization (greater than 50 colony-forming units granulocyte-macrophage [CFU-GM] per 10(5) mononuclear cells) was achieved when prior chemotherapy did not exceed 1 year and when GM-CSF was used post-HD-CTX; similarly, rapid platelet recovery to 50,000/microL within 2 weeks was associated with "good" PBSC mobilization. These same variables also predicted for rapid engraftment after autotransplantation, so that hematologic recovery (granulocytes greater than 500/microL and platelets greater than 50,000/microL) proceeded within 2 weeks among the 37 patients with "good" PBSC collection. As a result of rapid neutrophil recovery (greater than 500/microL) within a median of 2 weeks, infectious complications both post-HD-CTX and posttransplant were readily manageable, resulting in only one treatment-related death post-HD-CTX. The cumulative response rate (greater than or equal to 75% cytoreduction) for all 75 patients was 68%, with 12-month event-free and overall survival projections of about 85%. Using both bone marrow and PBSC together with GM-CSF, autotransplants are safe and appear effective in myeloma, especially when prior therapy had been limited to less than 1 year. More than 80% of transplanted patients achieved complete hematologic recovery within a median of 1 month posttransplant (granulocytes greater than 1,500/microL; platelets greater than 100,000/microL; hemoglobin greater than 10 g%), thus providing sufficient hematopoietic reserve for further chemotherapy in the event of posttransplant relapse.

High-dose busulfan in patients with myeloma.

    To evaluate the use of high-dose busulfan (HDB) with autologous bone marrow transplantation (ABMT) in patients with myeloma.. Fifteen patients received HDB (16 mg/kg), eight of whom received high-dose melphalan (HDM) but had experienced a short remission or progression-free interval. Two patients had received HDM on two previous occasions, one had no response to low-dose melphalan, and four had impaired renal function (edathamil clearance < 40 mL/min). All patients received induction chemotherapy before HDB.. Two patients were in complete remission (CR) after induction chemotherapy before HDB. Of the remaining 13 patients, four (31%) achieved CR and two (15%) achieved a partial remission for an overall response rate of 46%. There were three treatment-related deaths, but the toxicity was otherwise predictable and manageable.. In heavily pretreated patients, HDB results in a relatively high response rate. It can also be used safely in patients with renal impairment who are not suitable for HDM.

Consolidation hemibody radiotherapy following induction combination chemotherapy in high-tumor-burden multiple myeloma.
    Journal of clinical oncology : official journal of the American Society of Clinical Oncology, 1992, Volume: 10, Issue:11

    Curative therapy for multiple myeloma continues to be an elusive goal. This report discusses the Northern California Oncology Group (NCOG) phase I and II trial in high-tumor-burden disease that used a strategy that consisted of induction chemotherapy (vincristine, melphalan, cyclophosphamide, and prednisone [VMCP]) for eight cycles followed by sequential hemibody radiation therapy (RT) and subsequent chemotherapy for an additional eight cycles.. Seventy-two previously untreated stage III myeloma patients were entered onto the study. Sixty-nine received induction chemotherapy, 40 received induction chemotherapy and hemibody RT, and 23 received induction chemotherapy, hemibody RT, and consolidative chemotherapy.. Twenty-two complete responses (CRs) were obtained by induction chemotherapy, with four additional CRs after RT and consolidative chemotherapy. Nineteen patients developed grade 4 hematologic toxicity primarily after upper hemibody RT. Eight of these developed long-standing neutropenia or thrombocytopenia. Median survival of the group was 134 weeks, which was not significantly different from other approaches.. Hemibody RT can be combined with chemotherapy as induction therapy and can be safely administered in a community setting. However, as administered here no survival advantage was demonstrated.

Investigations of the frequency of DNA strand breakage and cross-linking and of sister chromatid exchange frequency in the lymphocytes of patients with multiple myeloma undergoing cytostatic therapy with melphalan and prednisone.
    Carcinogenesis, 1992, Volume: 13, Issue:11

    An investigation was made of 17 patients with multiple myeloma using the method of alkaline filter elution for the detection of DNA damage and the determination of sister chromatid exchange (SCE) frequency in peripheral lymphocytes during a course of chemotherapy with melphalan and prednisone. We were able to detect elevated SCE frequencies in pretreated patients that approximately doubled during the therapeutic cycle. An appreciable level of DNA cross-linking was detected by alkaline filter elution; DNA cross-linking scarcely increased during a course of chemotherapy. The increase in the SCE frequency during the first therapy cycle was even greater in the case of patients with newly diagnosed multiple myelomas. The results obtained by alkaline filter elution and measuring SCE frequencies suggest that these techniques are suitable as methods in molecular epidemiology, especially if applied to persons who are chronically exposed to cytostatic drugs. Whether or not the methods could be valuable in evaluating therapy response needs further investigation.

Non-secretory multiple myeloma presenting as primary plasma cell leukaemia.
    Postgraduate medical journal, 1992, Volume: 68, Issue:800

    A case of non-secretory multiple myeloma presenting as primary plasma cell leukaemia in a 65 year old woman is presented. Bone pain was the initial clinical manifestation. Laboratory analysis showed 20% of circulating immature plasma cells. Despite the presence of osteolytic lesions, no M-component could be demonstrated in serum protein electrophoresis, and serum and urine immunoelectrophoresis. Bone marrow aspirate demonstrated an 83% infiltration of plasma cells showing various degrees of immaturity. Immunofluorescence with monoclonal antisera demonstrated intracytoplasmic kappa light chains in a high percentage of plasma cells. Immature plasma cells without cellular capacity to synthesize and excrete complete immunoglobulins could be more aggressive, leading to an initial leukaemic process. Previous work regarding possible pathogenetic mechanisms, clinical and laboratory features, and response to treatment of this extremely rare association are reviewed.

Treatment of melphalan-resistant multiple myeloma with vincristine, BCNU, doxorubicin, and high-dose dexamethasone (VBAD).
    European journal of cancer (Oxford, England : 1990), 1992, Volume: 29A, Issue:1

    A total of 65 patients (35 male/30 female) with multiple myeloma primarily (33) or secondarily (32) resistant to melphalan and prednisone were treated with vincristine, carmustine (BCNU), doxorubicin, and high-dose dexamethasone (VBAD) at 4-week intervals. Among 60 evaluable patients the overall response was 36.6% (21.6% objective response plus 15% improvements). The response rate was significantly higher in primarily resistant patients than in those becoming resistant after a prior response (48.4 vs. 24.1%, P < 0.05). The median duration of response was 17.5 months. When survival of responders and non-responders were compared by the conventional method, a highly significant difference was observed (P < 0.001). However, using the Mantel and Byar procedure and the landmark method, only a trend for longer survival in the responders was registered. These results indicate that although VBAD is effective in at least one third of patients with advanced multiple myeloma resistant to melphalan, its impact on survival is limited.

Primary dexamethasone treatment of multiple myeloma.
    Blood, 1992, Aug-15, Volume: 80, Issue:4

    Intermittent courses of dexamethasone (DEX) were administered to 112 consecutive, previously untreated patients with multiple myeloma (MM). Using criteria based on a 75% or greater reduction of calculated tumor mass, the overall response rate was 43%. Among comparable patients, response rate were approximately 15% less than those observed previously with vincristine-doxorubicin by continuous infusion with intermittent DEX (VAD) and similar to those with melphalan-prednisone. The projected survival times with VAD or DEX were similar. Results indicated that DEX accounted for most of the plasma cell reduction achieved with VAD. Serious complications occurred in 27% of patients treated with VAD, but in only 4% of those who received DEX. In view of the similar outcome with fewer serious complications, DEX provided a simple, effective, and safe primary treatment for a large fraction of patients with MM. Patients who appear most likely to benefit include those with hypercalcemia or pancytopenia, or who require simultaneous radiotherapy for a pathologic fracture.

Serum concentration of the cross-linked carboxyterminal telopeptide of type I collagen (ICTP) is a useful prognostic indicator in multiple myeloma.
    British journal of cancer, 1992, Volume: 66, Issue:2

    Type I collagen is the main collagen type found in mineralised bone. Specific immunoassays for PICP (carboxyterminal propeptide of type I procollagen) and ICTP (cross-linked carboxyterminal telopeptide region of type I collagen) allow simultaneous assessment of the synthesis and degradation of type I collagen in serum samples, respectively. Our aim was to find out whether these metabolites of type I collagen are useful markers for following bone turnover and evaluating treatment response in multiple myeloma, which is a good model disease of excessive osteolysis. Fifteen consecutive patients were studied before and throughout their treatment. Samples for serum PICP and ICTP were collected before starting each treatment course of melphalan and prednisolon. Response to treatment was evaluated by following the changes in M protein and bone roentgenograms. The disease was progressing in four and regressive in 11 patients, but in four of these a recurrence occurred. In nonresponders the ICTP concentration was permanently elevated despite treatment. In responders both increased or normal levels of ICTP were initially observed, but they returned to or remained in the reference interval during treatment. The ICTP concentration increased upon recurring disease. There was a strong correlation between the extent of bone lesions and ICTP. There was no correlation between ICTP and PICP, the latter mainly remaining within the reference range, a finding that suggests no change in bone formation. ICTP was a significant predictor for survival in this patient group (P less than 0.05). We conclude that ICTP is a specific and sensitive marker for bone resorption. Simultaneous use of serum ICTP and PICP offers an additional and easy means to follow bone turnover and evaluate the response to therapy in multiple myeloma.

Bence-Jones myeloma with pleural effusion: response to alpha-interferon and combined chemotherapy.
    Internal medicine (Tokyo, Japan), 1992, Volume: 31, Issue:5

    A 73-year-old female patient with myelomatous pleural effusions is described. She was admitted to our hospital with lumbago and emaciation. Laboratory findings revealed cytopenia and hypogammaglobulinemia. Immunoelectrophoresis demonstrated Bence-Jones monoclonal protein in the serum, but not in the urine. Bence-Jones myeloma was diagnosed by the bone marrow aspiration. Chest X-ray film, however, showed bilateral pleural effusions. Fluid cytology revealed numerous immature plasma cells, indicating pleural involvement. Intrapleural administration of alpha-interferon combined with systemic chemotherapy (oral melphalan-prednisolone with alpha-interferon im.) was successful in maintaining the resolution of pleural effusions. Intrapleural alpha-interferon administration seems to be effective in the management of myelomatous pleural effusions.

Myeloma cell resistance to melphalan, BCNU and epirubicin determined in vitro with the 3H-thymidine incorporation technique prior to chemotherapy.
    Neoplasma, 1992, Volume: 39, Issue:1

    Drug resistance of marrow plasma cells had been measured in vitro before chemotherapy was started. Resistance to melphalan was found in 20, to BCNU in 27 and to epirubicin in 38 out of 65 myelomas. Nineteen myelomas were resistant to a single cytostatic, 14 to two cytostatics and further 13 to all three. Patients with plasma cells resistant to melphalan in vitro failed to reduce 50% of monoclonal Ig plasma level after therapy along the VBMCP (M2) protocol, whereas sensitive myelomas responded to this program satisfactorily. Patients with cells resistant to two or three cytostatics, beside a bad therapeutic response, had also a shorter survival time. Results in vitro were in conformity with in vivo effects in 78%.

Flow cytometric DNA analysis and clinical correlations in multiple myeloma.
    American journal of clinical pathology, 1992, Volume: 97, Issue:3

    DNA content of both bone marrow and peripheral blood mononuclear cells was measured by flow cytometric analysis in 46 patients with untreated multiple myeloma and 15 patients with benign monoclonal gammopathy to clarify further the incidence and clinical correlations of DNA aneuploidy. Aneuploidy was detected in the bone marrow of 25 multiple myeloma patients (54%) but in only one benign monoclonal gammopathy patient (7%), who developed multiple myeloma 34 months later. Thus DNA aneuploidy is considered rare in benign monoclonal gammopathy. In two multiple myeloma patients, DNA aneuploidy was detected also in blood, indicating circulating myeloma cells. The light chain of the M component was more frequently lambda in the diploid and kappa in the aneuploid group. Most of the patients with only light chain secretion were DNA aneuploid. Multiple myeloma patients with DNA hypodiploidy (7%), biclonal aneuploidy (4%), or DNA aneuploidy detectable in blood (4%) did not respond to therapy with melphalan and prednisone. Survival was not influenced by DNA content. No DNA aneuploidy was detected in the bone marrow or the peripheral blood of 26 patients with chronic lymphocytic leukemia or two patients with Waldenström's macroglobulinemia.

    A 56-year-old man complained of general malaise, diffuse bone pain, nocturnal sweating, lack of appetite and weight loss (7 kg within one year). Pain in the pelvic and lumbar regions markedly impaired movement. Roentgenologically, multiple lucencies were visualised in many skeletal areas. Examination of the bone marrow revealed an increase in the proportion of atypical plasma cells to 40%. The IgG concentration was 29.8 milligrams, mainly monoclonal immunoglobulins of the IgG-kappa type, which reacted against nuclear antigens (68-kD-U1-RNP nuclear protein) with a 1:2,000 titre. The symptoms markedly regressed under cyclical combined therapy with three times 5 mg melphalan daily for 4 days and 100 mg prednisolone daily for 7 days (a total of 24 cycles). At the same time the IgG concentration and the autoantibody titre decreased markedly and the patient became symptom-free.

[IgG-lambda-type multiple myeloma with plasma-cell pericardial effusion and terminal plasma-cell leukemia].

    Monoclonal gammopathy of type IgG-lambda (IgG concentration 27.8 g/l) was discovered by chance in a 66-year-old woman with aortic and mitral valve disease. The patient declined any further diagnostic procedures. Three months later she experienced severe pain in the lumbar spine and developed decompensated cardiac failure with pulmonary and ankle edema. The IgG concentration had risen to 50.5 g/l. Echocardiography showed a large pericardial effusion and 600 ml of bloodstained fluid containing numerous plasma cells was aspirated (total protein 81.8 g/l, gamma-globulin 38.9%). Iliac crest biopsy showed diffuse infiltration with polymorphic plasma cells, but the differential count in peripheral blood was unremarkable. Multiple myeloma of Stage IIa was diagnosed and she was given cytostatic therapy with 17.5 mg melphalan and 112 mg methylprednisolone daily by mouth (for 4 days at intervals of 6 weeks). Though at first the IgG concentration fell, it later rose again. The beta 2-microglobulin level was raised at 30 mg/l. After three cycles of chemotherapy the patient complained of severe pain in the hips and thighs. The blood film now showed numerous, predominantly immature plasma cells. A few days later, having been ill for four months in all, she died, showing all the signs and symptoms of plasma cell leukaemia.

[Study on the therapy of multiple myelomas--initial induction therapy (MP, IFN alpha, steroid pulse) and maintenance therapy (VMP, MP continuous, VEP, MCNU)].
    [Rinsho ketsueki] The Japanese journal of clinical hematology, 1992, Volume: 33, Issue:5

    Untreated twenty patients of multiple myeloma were treated with the chemotherapy protocol as follows: Initial induction therapy;MP continuous or MP intermittent----IFN alpha----steroid pulse. Maintenance therapy;alkylating agents which have no cross resistance were used ((V) MP----(MP)----(V) EP----MCNU). Remission rate (CR+PR) after the initial MP therapy was 45%, and that after including IFN alpha and steroid pulse therapy was 50%, Fifty percent survival rate was almost as same as those reported previously (34M). Our protocol presented here was based on the idea that, initially, myeloma cells with proliferative activity could be affected by MP therapy, and subsequent IFN alpha therapy would have effect even on the residual myeloma cells. Serial checks of 3H-TdR uptake of myeloma cells during the therapy supported this idea. During the maintenance therapy, clinical responses to the initial induction therapy were not aggravated in the responded cases when evaluated by the variation of serum M-protein level. We propose that considering from a point of proliferative activity of myeloma cells is important for designing therapeutic protocols for multiple myeloma.

High-risk multiple myeloma treated with high-dose melphalan.
    Journal of clinical oncology : official journal of the American Society of Clinical Oncology, 1992, Volume: 10, Issue:1

    This study was undertaken to evaluate the efficacy and toxicity of high-dose melphalan (HDM) 140 mg/m2 in poor-risk multiple myeloma (MM).. Thirteen patients were previously untreated, and 13 had been pretreated with vincristine, Adriamycin (doxorubicin; Adria Laboratories, Columbus, OH), and dexamethasone (VAD) for refractory or relapsed MM.. All 11 fully assessed, untreated patients responded, and six achieved a complete response. Remissions were of excellent quality, but response duration--a median of 16 months--was short. This was probably due to the high incidence of unfavorable prognostic signs, like a high beta 2-microglobulin (B2M) and/or a high plasma cell labeling index (LI). None of the nine pretreated patients with a measurable M component had more than 50% reduction of M component after HDM, indicating that intensive treatment has no effect on a residual tumor population. The relapse-free period after HDM in this group of patients (median, 9 months) was not better than in a historical control group of patients treated with VAD alone. The major complications due to the prolonged myelosuppression were severe infections. After primary HDM, median time to recovery to greater than 0.5 x 16(9) granulocytes was 30 days; in previously treated patients, the recovery period was even longer. There were three toxic deaths. Fulminant relapses with features of J-chain disease were frequently observed, indicating a dedifferentiated tumor, probably induced or selected by the HDM.. HDM is an effective treatment resulting in good remissions for untreated MM. However, other therapy strategies should be explored first, focusing on the reduction of toxicity and prolongation of the relapse-free period, before HDM can be recommended as first-line treatment for the younger MM patient.

Flow cytometry for clinical estimation of circulating hematopoietic progenitors for autologous transplantation in cancer patients.
    Blood, 1991, Jan-15, Volume: 77, Issue:2

    Optimum methods of harvesting circulating hematopoietic progenitors for autologous transplantation to support myeloablative cancer therapy are still uncertain, mostly because of the lack of an assay for marrow-repopulating stem cells. The CFU-GM assay, the commonly used indirect indicator of the quality of the graft, is poorly standardized and provides results evaluable only retrospectively. Based on the knowledge that hematopoietic progenitors express CD34 and CD33 differentiation antigens, we developed a dual-color direct immunofluorescence flow cytometry assay with the aim of replacing the CFU-GM assay advantageously. For this purpose, we applied both assays to 157 blood samples obtained daily throughout 20 different recoveries from pancytopenia induced by high-dose cyclophosphamide or etoposide cancer therapy with or without recombinant human GM colony-stimulating factor (rhGM-CSF). The appearance of CD34+ cells in the circulation indicated that hematopoietic progenitors had increased to more than 500 CFU-GM/mL, a level clinically adequate for large-scale harvest by leukapheresis. Total CD34+ cells correlated well with CFU-GM (r = .89), and data could be fitted by a linear regression line described by the equation y = 388.3 + 64.0x, where y = CFU-GM/mL and x = CD34+ cells per microliter. Moreover, in a series of six patients treated with myeloablative chemoradiotherapy, early hematopoietic recovery of marrow functions was predicted more accurately by the number of transplanted CD34+/CD33+ cells than by either total nucleated cells, CFU-GM, CD34+/CD33- cells, or CD34-/CD33+ cells. Data presented in this article favor clinical use of the CD34/CD33 flow cytometry assay to guide harvesting of circulating hematopoietic progenitors for autologous transplantation and contribute to better understanding of the role played by circulating hematopoietic progenitor cell subsets in marrow recovery after myeloablative cancer therapy.

Influence of interferon on antibody production and viability of malignant cells from patients with multiple myeloma.
    European journal of haematology, 1991, Volume: 46, Issue:1

    The influence of interferon (IFN) on antibody production and viability of malignant cells from patients with multiple myeloma was evaluated. Following incubation of bone marrow cells with IFN-alpha (5000 units/ml) for 7 days) a decreased production of monoclonal immunoglobin (mlg) was detected in all experiments except one. IFN induced a greater than 50% decrease in myeloma cell viability in 11 patients and a greater than or equal to 25% decrease in 4 patients, whereas in myeloma cells from 8 patients IFN had no or only minor effects. The observed effect was not due to an inhibition of proliferation since less than 5% of the myeloma cells were labeled with [3H]-thymidine during 7 d of culture. There was no statistically significant correlation between decreases in myeloma cell viability and effects on mlg production, exemplified by the fact that mlg production was decreased also in patients showing no sensitivity to IFN's cytotoxic action. Depletion of autologous T-cells, NK-cells and/or monocytes did not abrogate the effects observed. We conclude that IFN can reduce the viability of myeloma cells and the production of Ig from these cells and that the latter can be exerted without an antitumor effect.

Interphase cell death as related to the cell cycle of melphalan-treated human myeloma cells.
    Medical oncology and tumor pharmacotherapy, 1991, Volume: 8, Issue:2

    The effect of melphalan on cell loss, cell growth and cell-cycle traverse was studied on the human myeloma cell line RPMI 8226. Melphalan treatment resulted in arrest of cells in late S- and G2-phases in a population of unsynchronized cells. At high concentrations of melphalan (e.g. 40 microM), cell loss was noticed during the first cell cycle after melphalan treatment in addition to the aforementioned arrest of cells in late S and G2. The cell loss after melphalan treatment was further analysed in cells enriched for G1-phase. Cell death in this population of cells occurred between 24 and 48 hr after treatment as the cells were in S and moving over to G2.

[Extraskeletal diffusion of multiple myeloma. A clinico-pathological description of 4 cases].
    Recenti progressi in medicina, 1991, Volume: 82, Issue:11

    The authors describe 4 cases of multiple myeloma that developed one or more extraskeletal localizations. They have evaluated the relation between the onset of the extraskeletal localizations and the following myeloma characteristics: tumor burden, clinical phase, chemotherapy response, prognostic significance. All the patients showed these localizations in a plateau phase of myeloma. None of the patients had fever, pancytopenia and in no one the performance status worsened. All patients obtained at least a partial reduction of the localization and only the patient with the retro-orbital localization, got worse and died for myeloma. The other three patients are alive and do not show any sign of progression.

Three cases of multiple myeloma developing into melphalan-related chronic myelomonocytic leukemia.
    Journal of medicine, 1991, Volume: 22, Issue:3

    From 1980 to 1987, three cases of chronic myelomonocytic leukemia (CMML) were encountered among 68 cases of multiple myeloma who survived more than three years from the diagnosis. The incidence (4.8%) of secondary myelodysplastic syndrome (MDS) is almost identical to previous reports, but case reports of chronic myelomonocytic leukemia were rare. In Japan, there are few reports of multiple myeloma patients who later developed secondary MDS or acute myelogenous leukemia (AML). In our cases, none of the 31 patients treated with cyclophosphamide developed secondary MDS, while three of 37 patients treated with melphalan developed CMML. This difference is not statistically significant.

[Immunological and rheological disorders in multiple myeloma patients].
    Terapevticheskii arkhiv, 1991, Volume: 63, Issue:7

    Overall 30 patients with multiple myeloma (MM) were examined for immunological and rheological parameters. MM was shown to be marked by imbalance of immunobiological reactivity, with the greatest changes being seen in the B cell immunity system. MM is also characterized by marked rheological shifts related to the immunological alterations and underlying the hyperviscosity syndrome and heart failure. Administration of polychemotherapy resulted in a decrease of the count of B lymphocytes, circulating immune complexes; a tendency toward normalization of the rheological blood properties was observed. Introduction of plasmapheresis into the treatment program of the patients noticeably raised the treatment efficacy.

[The effect of different programs of cytostatic therapy on the blood coagulation and rheological properties in multiple myeloma patients].
    Terapevticheskii arkhiv, 1991, Volume: 63, Issue:7

    Three different programs of polychemotherapy (PCT) of multiple myeloma (MM) were compared. The programs included the use of cyclophosphamide (up to 750 mg/m2), vincristine (1.4 mg/m2), rubomycin (40 mg/m2), sarcolysine (7.5 mg/m2), paphencyl (50 mg/day) and prednisolone (from 30 to 60 mg/m2) in different combinations with regard to the hemocoagulation and rheological blood properties. It has been shown that in patients with MM there occur profound hemocoagulation and rheological alterations playing an important part in the genesis of the syndrome of hyperviscosity and circulation failure. The use of the programs of PCT in conjunction with therapeutic plasmapheresis brought about an appreciable improvement of the patients' general health status and correction of hemocoagulation and hemorheological disorders. To control the efficacy of PCT, its individualization, intensity and duration, it is recommended that in addition to the common tests, the activity of the antithrombin-III-heparin complex may be measured and the test for the presence of fibrin monomer in the plasma be made, since these parameters clearly reflect the changes in the system of hemostasis and enable one to discover the early signs of proliferation activation in MM thereby preventing hemorrhages.

Interaction of melphalan and dexamethasone in a human myeloma cell line.
    Anti-cancer drugs, 1991, Volume: 2, Issue:6

    The effects of a combination of melphalan and dexamethasone on cell growth, cell cycle flow, cell loss and DNA cross-links were studied on a myeloma cell line (RPMI 8226). At low concentrations melphalan reduced the cell growth by prolonging the S and G2 stages. Steroid sensitivity of the cell line was characterized by dose-dependent inhibition of cell growth after exposure of up to 1 micron dexamethasone with no cell loss found even at 10-fold saturation concentration. Dexamethasone induced prolongation of all cell cycle phases without any preferences. In combined treatment with melphalan and dexamethasone, inhibition of cell growth was found after 24 h followed by cell loss after 48 h. This cell loss was obtained with concentrations of the drugs which by themselves are only growth inhibitory. Calculation of cell flow showed that cell loss is a delayed process occurring after the cells have left the G1 phase. By alkaline elution it was found that dexamethasone treatment caused an increase in melphalan-induced DNA interstrand crosslinks.

Combination therapy of M2-protocol and interferon-alpha as remission induction in refractory multiple myeloma.
    Haematologia, 1991, Volume: 24, Issue:1

    A successful induction of remission in two patients with resistant multiple myeloma using a new combination therapy of modified M-2 protocol and interferon-alpha (IFN-alpha) is described. The first case was a 32-year-old man with K type urinary Bence-Jones protein who became resistant after treatment with melphalan and prednisone (MP protocol). IFN-alpha alone had a marginal response. The modified M-2 protocol proved insufficient. Therefore, IFN-alpha was administered in the interval of M-2 protocol. This combination therapy showed remarkable responses. The second case was a 59-year-old woman with advanced IgA myeloma who was treated with M-2 protocol and became resistant. IFN-alpha alone resulted in a slight response. After addition of IFN-alpha to the modified M-2 protocol, a rapid reduction in the level of serum IgA was found and clinical symptoms including bone pain, anaemia and so on were dramatically improved. No infection and/or intolerable side effects were observed in either case. This combination treatment appears worthy to try in cases of resistant or relapsing myeloma patients.

Efficacy of peptide bound m-L-sarcolysin (peptichemio) on melphalan resistant human myeloma cells in vitro.
    Medical oncology and tumor pharmacotherapy, 1991, Volume: 8, Issue:4

    Peptichemio (PTC) is a mixture of six synthetic oligopeptides, each containing the alkylating agent m-di(2-chloroethyl)amino-phenylalanine. Freshly obtained myeloma cell infiltrated human bone marrow specimens were in parallel exposed to melphalan and PTC. The cytotoxic effect of the drugs on the myeloma cells of each specimen was measured by the differential staining culture method (DISC). PTC displayed higher cytotoxicity to the myeloma cells as compared to melphalan in all 12 cases analysed. The increase of the cytotoxic effect of PTC compared to melphalan varied between different cases. In melphalan resistant cases the cytotoxic effect of PTC as compared to melphalan was clearly significant (P = 0.001).

Diurnal variations of serum beta 2-microglobulin in multiple myeloma.
    Life sciences, 1991, Volume: 49, Issue:6

    The chronobiological circadian behaviour in serum levels of beta 2-microglobulin has been investigated in three groups of subjects: (A) 6 healthy controls; (B) 6 patients with untreated multiple myeloma; (C) 6 patients with multiple myeloma in complete remission after polychemotherapy. From all subjects, under the same standard life conditions, venous blood samples were drawn at 4-hour intervals starting from midnight during the span of a whole day. Circulating serum beta 2-microglobulin levels were determined by RIA method. The time-related data were analyzed by chronograms and the "mean-group cosinor" method. A significant circadian rhythm for serum beta 2-microglobulin was detected in the control group, with a peak in the morning hours, and in untreated patients, with a peak in the afternoon hours. No significant rhythm was found in treated patients with multiple myeloma. A significant mesor reduction was noted in patients with complete remission, correlated with the absence of circadian rhythm, in respect to untreated patients. These data suggest that serum levels of beta 2-microglobulin could be related to the neoplastic plasma cell proliferation and to the effect of therapy, and that the circadian evaluation could be used as a guide in monitoring myeloma patients.

Development and characterization of a melphalan-resistant human multiple myeloma cell line.
    Cancer research, 1991, Feb-01, Volume: 51, Issue:3

    We present data describing a human myeloma cell line (8226/LR-5) selected for resistance to melphalan which exhibits a 7-fold level of resistance to melphalan and is partially cross-resistant to other bifunctional alkylators and X-irradiation. Melphalan resistance is relatively unstable with a decrease in resistance observed within 17 weeks in the absence of drug. The resistance observed in this cell line is not mediated by reduced intracellular melphalan accumulation. DNA interstrand cross-linking at equivalent intracellular drug accumulation is significantly reduced in the resistant subline. Whether this reduction is the result of a decrease in the formation of this lesion or to an increased rate of removal of the lesion remains to be determined. Growth characteristics and cell cycle kinetics, including S phase, were similar between sensitive and resistant cell lines. Intracellular nonprotein thiols were found to be significantly elevated in the resistant 8226/LR-5 cells; as cells revert or lose resistance, intracellular nonprotein sulfhydryl levels decline. Prior treatment of the cells with buthionine sulfoximine significantly reduced nonprotein sulfhydryl levels and enhanced melphalan cytotoxicity in both the sensitive and resistant cell lines. Thiols appear to play a role in mediating melphalan resistance.

Monoclonal antibody-purged autologous bone marrow transplantation therapy for multiple myeloma.
    Blood, 1991, Feb-15, Volume: 77, Issue:4

    Eleven patients with plasma cell dyscrasias underwent high-dose chemoradiotherapy and anti-B-cell monoclonal antibody (MoAb)-treated autologous bone marrow transplantation (ABMT). The majority of patients had advanced Durie-Salmon stage myeloma at diagnosis, all were pretreated with chemotherapy, and six had received prior radiotherapy. At the time of ABMT, all patients demonstrated good performance status with Karnofsky score of 80% or greater and had less than 10% marrow tumor cells. Eight patients had residual monoclonal marrow plasma cells and 10 patients had paraprotein. Following high-dose melphalan and total body irradiation (TBI) there were seven complete responses, three partial responses, and one toxic death. Granulocytes greater than 500/mm3 were noted at a median of 21 (range 12 to 46) days posttransplant (PT) and untransfused platelets greater than 20,000/mm3 were noted at a median of 23 (12 to 53) days PT in 10 of the 11 patients. Natural killer cells and cytotoxic/suppressor T cells predominated early PT, with return of B cells at 3 months PT and normalization of T4:T8 ratio at 1 year PT. Less than 5% polyclonal marrow plasma cells were noted in all patients after transplant. Three of the seven complete responders have had return of paraprotein, two with myeloma, and have subsequently responded to alpha 2 interferon therapy. Eight patients are alive at 18.9 (8.9 to 43.1) months PT and four remain disease-free at 12.3, 17.5, 18.9, and 29 months PT. This preliminary study confirms that high-dose melphalan and TBI can achieve high response rates without unexpected toxicity in patients who have sensitive disease, and that MoAb-based purging techniques do not inhibit engraftment. Although the follow-up is short- and long-term outcome to be determined, relapses post-ABMT in these heavily pretreated patients suggest that ABMT or alternative treatment strategies should be evaluated earlier in the disease course.

Lack of correlation between objective response and death rate in multiple myeloma patients treated with oral melphalan and prednisone.
    Annals of oncology : official journal of the European Society for Medical Oncology, 1991, Volume: 2, Issue:3

    An analysis of survival by response category was performed on 76 patients with stage II and III multiple myeloma, who were treated with oral melphalan and prednisone. The analysis demonstrated a survival advantage for responders over non-responders only in stage III patients (32.3 months for responders vs. 15.6 months for non-responders, p = 0.03). However, two possible sources of error must be considered: a) the poor prognosis of early responders that may adversely affect the survival of all responders, and b) the bias introduced by the 'guarantee time' of responders (i.e., the time on-study required to detect the response). Exclusion from the analysis of the unfavourable subgroup of 'early' responders (median survival 14.7 mos.) provided an improvement of the difference in survival between the remaining 'slow' responders and non-responders in stage III (p = 0.005) as well as in the series as a whole (p = 0.025). Because of the consistent 'guarantee time' of slow responders, the Mantel-Byar test (which credits survival to responders only after the response has been obtained) was then applied. The survival advantage of slow responders over non-responders, previously observed in all patients, particularly those with stage III, was not confirmed by the Mantel-Byar test (chi-square 0.831 and 1.457, respectively), thus supporting the hypothesis of an equal death rate over time in each response category. It therefore appears that the usual response criteria (which require at least a 50% reduction of the myeloma protein) should perhaps be reassessed, as they seem to be an inadequate parameter for evaluation of treatment effectiveness in multiple myeloma.

    A 71-year-old man was hospitalized in November, 1983 for a back pain and a diagnosis of multiple myeloma was made, based on the Bence Jones proteinuria, The serum M-component of a IgG-kappa type (3.3 g/dl), and plasmacytosis in the bone marrow (37%). Treatment consisted of melphalan and prednisolone. A blood count in March, 1986 revealed 6000/microliters of WBC with 30% of a blast form and 8% plasma cells, and 20,000/microliters of platelets. A bone marrow aspirate revealed that 14% were myeloblasts and 26% were plasma cells. Distinguishing the myeloblasts from the immature plasma cells in the peripheral blood proved difficult. Studies by electron microscopy and an immunological inspection of phenotypes were helpful in achieving a determination. A karyotypic analysis of the bone marrow cells indicated a hypodiploid cell population, a marker chromosome, and a karyotypic instability. These findings indicate that his multiple myeloma had undergone a leukemic change associated with acute myelogenous leukemia.

Adult Fanconi syndrome secondary to kappa-light chain myeloma: improvement of tubular functions after treatment for myeloma.
    Nephron, 1990, Volume: 55, Issue:3

    A 66-year-old man with kappa-light chain multiple myeloma had adult Fanconi syndrome. Renal tubular transport abnormalities consisted of renal tubular acidosis, renal glycosuria, aminoaciduria, phosphaturia and renal hypouricemia. After therapy for multiple myeloma, urinary Bence Jones protein became undetectable, and all these renal tubular abnormalities except urate wasting were corrected. Histological examination revealed electron-dense tubular and rod-like deposits in proximal tubular epithelium. This clinical observation suggests that the renal tubular transport defects were secondary to the myeloma process, possibly due to Bence Jones proteinuria.

    Eight patients with progressive multiple myeloma were given an intermediate intravenous dose of melphalan (30 mg/m2). A response lasting 2-18 months was observed in 7 patients. The bone marrow toxicity was well acceptable and most courses could be given on an outpatient basis. Intermediate-dose intravenous melphalan may be considered an alternative for treatment of relapsing or progressive multiple myeloma, even if the patient has previously received oral melphalan.

    A 66-year-old female was admitted to our hospital with lumbago. On admission, laboratory examination revealed hemolytic anemia. Direct Coombs' test was positive, and also direct monospecific-Coombs' test by anti-C3d serum was positive. Immunoelectrophoresis showed IgA-lambda type M proteins in serum. Bone marrow aspiration disclosed increased atypical plasma cells. X-ray of skull showed punched-out lesion. From these findings, she was diagnosed as IgA (lambda) myeloma complicating with autoimmune hemolytic anemia. Hemolysis was improved by chemotherapy. It was thought that IgA and C3 were related well to hemolysis in this case.

Ondansetron--a new safe and effective antiemetic in patients receiving high-dose melphalan.
    Cancer chemotherapy and pharmacology, 1990, Volume: 25, Issue:6

    A total of 33 patients with myeloma receiving treatment with high-dose melphalan (140-200 mg/m2 i.v.) were given the 5HT3 antagonist Ondansetron (Glaxo) as an antiemetic. In 42% of patients, emetic episodes were either abolished (15%) or reduced to two or less (27%). Efficacy was not related to scheduling (two regimens) or total dose. No sedative or other significant side effects were seen. Ondansetron is a highly effective non-sedative antiemetic that justifies further assessment in combination with other antiemetics in patients receiving cytotoxic drugs associated with the production of severe nausea and vomiting.

Oral dosage of melphalan and response to treatment in multiple myeloma.
    European journal of cancer (Oxford, England : 1990), 1990, Volume: 26, Issue:3

    Forty-nine consecutive patients with multiple myeloma were analysed for treatment response in relation to dose of orally administered melphalan (induction therapy). All patients were given at least six courses of melphalan-prednisone. Treatment response, defined as a reduction of the myeloma protein of greater than 50%, was seen in 26 patients while 23 were non-responders. When treatment response was related to the dosage of melphalan given by mg/kg of body weight, the numbers of responding and non-responding patients were similar in the group of patients without dose reduction as well as in that with dose reduction. Drug-induced suppression of white blood cell and platelet count was similar in the responding as well as in the non-responding group indicating that the reason for non-response is not simply explained by deficient drug absorption. When the cumulative dose of melphalan given during the induction therapy was analysed, however, a positive correlation (r = 0.47, P less than 0.001) was seen between the cumulative dose and the degree of response. Thus, the cumulative dose of melphalan given during induction therapy seems to be of importance for the response, but other factors as intrinsic differences in cell sensitivity may also explain the individual responsiveness.

High-dose melphalan and granulocyte-macrophage colony-stimulating factor for refractory multiple myeloma.
    Blood, 1990, Aug-15, Volume: 76, Issue:4

    High-dose melphalan has induced remissions in about 40% of patients with refractory myeloma, but the mortality has been high, at about 20%, due to complications of prolonged granulocytopenia. In an attempt to stimulate earlier granulocyte recovery, recombinant human granulocyte-macrophage colony-stimulating factor (GM-CSF) was administered subcutaneously to 23 patients with refractory myeloma who had been treated with melphalan at a high dose of 100 mg/m2. Thirty-nine percent of patients achieved marked tumor cytoreduction by at least 75%, 2 died within 2 months from infectious complications during severe neutropenia; and median durations of relapse-free and overall survival were 7 and 10+ months, respectively. The nine patients presenting with both advanced age over 50 years and a long history of prior therapy of over 1 year required significantly longer median times of 31 days for granulocytes and of 63 days for platelets to reach safe levels of at least 500/microL and 50,000/microL, respectively, than the 14 remaining patients who had none or only one of these adverse features (21 and 26 days, respectively). In a historic control of 43 patients treated previously with high-dose melphalan but without GM-CSF, hematologic recovery to the aforementioned levels of granulocytes and platelets proceeded over almost 5 weeks, regardless of age and prior treatment exposure. Thus GM-CSF seems to hasten marrow recovery, especially in patients with adequate normal marrow stem-cell reserve as defined by younger age or less prior therapy. While not shortening the duration of neutropenia, GM-CSF dose increments (from 0.25 to 0.5 to 0.75 mg/m2) increased the incidence of severe toxicity from 0% to almost 40%, especially among older patients. These results support the usefulness of low-dose GM-CSF (0.25 mg/m2) in stimulating marrow recovery in selected patients with adequate marrow reserve treated with high-dose melphalan for refractory multiple myeloma.

Colony stimulating activity in the serum of patients with multiple myeloma is enhanced by interleukin 3: a possible role for interleukin 3 after high dose melphalan and autologous bone marrow transplantation for multiple myeloma.
    British journal of haematology, 1990, Volume: 75, Issue:3

    Sera from 36/37 multiple myeloma patients and 19/21 sera from patients with other solid or liquid tumours had granulocyte-macrophage colony stimulating activity (CSA) towards normal human donor bone marrow whereas 1/16 sera from normal donors had this activity. Unlike human rhGM-CSF and GM-CSF from 5637 (human bladder cell line) conditioned medium which is heat stable, CSA from serum is heat labile (56 degrees C/30 min). In multiple myeloma patients, CSA was detectable more than 2 years after treatment with 'high dose melphalan. Although multiple myeloma patients, at relapse, have sufficient CSA in their serum to produce maximal stimulation of GM-CFUc from normal donor bone marrow in vitro, their own GM population responds poorly. The results suggest that the failure of patients own bone marrow to respond to endogenous CSA may be due to damage to the stem cells of the marrow or the failure of precursor cells to respond to CSA. Addition of rhIL-3 to myelomatous serum increased the number of GM-CFUc from both normal and myelomatous bone marrow but did not stimulate the growth of MY-CFUc significantly. The results suggest that rhIL-3 may assist bone marrow recovery in multiple myeloma patients after intensive chemotherapy.

Autopsy-documented cure of multiple myeloma 14 years after M2 chemotherapy.
    Cancer, 1990, Oct-01, Volume: 66, Issue:7

    Multiple myeloma was diagnosed in a 65-year-old woman in 1974 who thereafter received five-drug M2 chemotherapy. All protein abnormalities subsequently returned to normal and serial bone marrow studies documented complete bone marrow remission. Destructive bone lesions persisted radiographically, but did not progress. In 1987, a localized sigmoid adenocarcinoma was resected. In 1988, the patient presented with multiple brain metastases associated with a primary pulmonary adenocarcinoma that proved rapidly fatal. At autopsy, no evidence of multiple myeloma was found. This report describes the first tissue-documented cure of multiple myeloma 14 years after diagnosis and initiation of M2 chemotherapy. The possible association of multiple myeloma with other malignancies is also discussed.

    [Rinsho ketsueki] The Japanese journal of clinical hematology, 1990, Volume: 31, Issue:6

    A 76-year-old female was admitted to our hospital because of anemia. Complete blood count was as follows: RBC 2.37 X 10(6)/microliters, Hb 7.7 g/dl, WBC 2,600/microliters, Plt 105 X 10(3)/microliters. A bone marrow aspirate revealed 40.8% plasmacytoid cells showing the characteristics of plasma cells by electron microscopy. Total serum protein was 5.4 g/dl. Monoclonal protein was not observed by electrophoresis. On immunoelectrophoresis, M-bow was not observed in the serum or in 50-fold concentrated urine. The plasma cells were negative for cytoplasmic IgG, M, A, E, D, kappa or lambda by immunoperoxidase studies. Although radiologic studies of the bones did not reveal destructive or punched out lesions, we diagnosed this case as a nonproducing myeloma and the patient responded to MP therapy. This case was considered interesting as regards the pathological entity of myeloma.

[Complete remission in multiple myeloma with natural interferon-alpha (HLBI) and melphalan/prednisolone intermittent therapy].
    [Rinsho ketsueki] The Japanese journal of clinical hematology, 1990, Volume: 31, Issue:6

    A 46-year-old man was admitted because of lumbago and numbness of the left leg. Pelvic X-ray showed a large defect in the left sacrum and CT revealed multiple punched-out lesions. Serum IgA was 1,740 mg/dl with a monoclonal component of IgA kappa by serum electroimmunofixation. Bence Jones protein of kappa type was detected in urine. Diagnosis of myeloma was made on the basis of histology of the biopsied sacral tumor. Repeated melphalan/prednisolone intermittent therapy (MP) was done with concomitant administration of natural interferon-alpha (IFN-alpha) 3 X 10(6) U intramuscularly for 67 days. Performance status including gait markedly improved. Normal bone marrow morphology and disappearance of M-protein by electroimmunofixation were achieved after 13 cycles of MP, when pelvic X-ray revealed prominent recalcification. No further treatment was instituted for subsequent 6 months, without any demonstrable M-protein. Complete remission of myeloma is rare with conventional therapies and thus new therapeutic modalities have been waited for. IFN-alpha may promise better responses if appropriately combined with other chemotherapies.

Autologous bone marrow transplantation in multiple myeloma: identification of prognostic factors.
    Blood, 1990, Nov-01, Volume: 76, Issue:9

    Multiple myeloma remains a universally fatal malignancy with a median survival time not exceeding 3 years. A clinical trial was undertaken to determine feasibility and efficacy of marrow-ablative chemoradiotherapy supported by unpurged autologous bone marrow (ABMT) and to define prognostic variables. Total body irradiation and either melphalan or thiotepa were administered to 55 patients (median age 53 years; range 20 to 66 years). The group of 21 patients with resistance to standard melphalan-prednisone and to continuous infusions of vincristine and Adriamycin with high dose dexamethasone (VAD) included 7 with primary unresponsive disease and 14 with resistant relapse; among the 34 patients achieving remission with the VAD regimen, 14 were in first and 20 in a subsequent remission. Marked cytoreduction by greater than or equal to 75% was observed among all 21 patients with refractory myeloma, whereas further cytoreduction of this magnitude was noted in only 56% of the 34 patients already in remission after VAD. Five of the 6 early deaths among all 55 patients occurred in the 14 patients with resistant relapse, none of whom achieved complete remission and who, as a group, had median durations of relapse-free and overall survival of only 8 and 7 months, respectively. Among the 41 remaining patients, there was only one early death, and 27% achieved complete remission including a 36% incidence among the 14 patients treated in first remission; their projected 4-year survival rate was 82% regardless of their disease status (first or later remission or primary resistance). When information about sensitivity to prior therapy is unavailable, the presence before ABMT of both high beta-2-microglobulin levels (greater than 3 mg/L) and non-IgG isotype helped identify 9 among the 55 patients with a very poor prognosis: all 8 responders relapsed within 9 months, and 8 patients died within 15 months. By contrast, a 4-year projected survival rate of over 70% for the other patients (about 80% of this series) justifies further investigation of this novel treatment approach in comparison with standard dose regimens. Our results indicate that marrow-ablative therapy cannot be recommended for myeloma patients with resistant relapse or those with a combination of risk factors (advanced tumor burden, absence of IgG isotype). The apparent lack of an adverse effect of even marked plasmacytosis in autografts (up to 30%) emphasizes the need for better cytoreduction rather than bone

Evidence that multiple myeloma may be regulated by homeostatic control mechanisms: correlation of changes in the number of clonogenic myeloma cells in vitro with clinical response.
    British journal of cancer, 1990, Volume: 61, Issue:3

    Myeloma colonies (MY-CFUc) could be grown in vitro for 6 months (median time) after a group of 12 myeloma patients had reached complete remission (CR). In a second group of 25 patients MY-CFUc increased in 17/25 and GM-CFUc in 20/25 patients after cyclophosphamide even though 24/25 patients had a partial response to VAMP and one was in CR. These data suggest that cell killing by cyclophosphamide stimulates residual tumour cells into proliferation and adds further support to the idea that myeloma is under some degree of homeostatic control which may be analogous to that in normal bone marrow. Although lymphoplasmacytoid myeloma cells may be more drug resistant than plasmacytoid myeloma cells in vitro, it was not possible to conclude that the emergence of lymphoplasmacytoid cells at relapse was indicative of resistance to further treatment.

    Sangre, 1990, Volume: 35, Issue:2

    The results achieved in a series of 63 patients diagnosed of multiple myeloma in one Centre between February 1981 and December 1984 are reported. One patient was in stage IA, 27 in stage II (A, 24; B, 3), and the remaining 35 were in stage III (A, 22; B, 13). The initial therapy consisted of courses of vincristine, cyclophosphamide, melphalan and prednisone combination chemotherapy (VCMP) given every 4th week. Among the 56 patients who were evaluable, 28 (50%) showed objective response, 6 (10.7%) clinical improvement, and therapeutical failure was seen in 14, whereas 8 patients died during the first two months of treatment. The haematological tolerance to VCMP was acceptable, but neurotoxicity due to vincristine appeared in 17.8% of the cases. Thirty-two patients showing resistance to VCMP at any given moment received vincristine, BCNU, adriamycin and prednisone or dexamethasone (VBAP/D) as salvage therapy, only 5 responses (15.6%) being achieved. Only 5 patients are still alive and the median survival of the series is 23 months. Progression of the disease and infections were the major causes of death.

Acute leukemia evolving from multiple myeloma and co-expressing myeloid and plasma cell antigens.
    American journal of hematology, 1990, Volume: 34, Issue:3

    This report describes the development of acute myeloblastic leukemia in a patient after long-term alkylator therapy for multiple myeloma. Despite chromosome deletions -5, -7, the patient lacked the histochemistry and clinical findings characteristic of therapy-induced leukemia. In double-labeled surface marker studies by flow cytometry, the leukemic blast cells co-expressed myeloid and plasma cell surface markers. The findings may support the hypothesis of a single stem cell abnormality's being responsible for both the malignant plasma cells and the myeloid leukemic cells.

Cytogenetic abnormalities in acute leukemia complicating melphalan-treated multiple myeloma.

    The cytogenetic findings in 11 patients with multiple myeloma in whom a myelodysplastic syndrome or an acute nonlymphocytic leukemia developed are reported. All patients were treated with oral melphalan for 2-9 years in a total dose of 0.5-4.1 g. When examined during the myelodysplastic or leukemic phase, all patients had an abnormal bone marrow karyotype, hypodiploid in nine of the 11 cases. The chromosome abnormalities were clearly nonrandom and comprised a 5q deletion in three cases, monosomy 5 in four cases, deletion 7q--in two cases, and monosomy 7 in three cases. Loss of material from the long arm of chromosomes 5, 7, or both was found in eight patients. The different chromosome abnormalities were not associated with any specific morphological or clinical features.

    In a 59-year-old man with multiple myeloma (kappa-light chain paraproteinaemia) in stage IIIB, bone marrow infiltration with atypical plasma cells was reduced by five cytostatic treatment courses with vincristine, melphalan, cyclophosphamide and prednisone (VMCP protocol), but anaemia requiring blood transfusion persisted (haemoglobin concentration 5.3 g/dl). Even administration of interferon alpha-2b (5 million units s.c. every other day) failed to alter this. Only a combination of interferon and erythropoietin (150 U/kg i.v. every other day) achieved lasting regression of the anaemia (haemoglobin concentration up to 14 g/dl). In four other anaemic patients with multiple myeloma, stage III, treated according to the VMCP protocol but without additional interferon, erythropoietin did not improve erythropoiesis.

    Seventy patients with progressive multiple myeloma received combination chemotherapy with cyclophosphamide and prednisolone (CP), BCNU, cyclophosphamide, procarbazine and prednisolone (BCPP), and MCNU, cyclophosphamide, melphalan and prednisolone (MCMP) as first line treatment. Total remission rate in patients treated with CP, BCPP, and MCMP was 76.2%, 86.1%, and 91%, and complete response rate 26.1%, 33.3% and 63.7%, respectively, 5-yr survival in the patients treated with CP and BCPP regimen was 51.9 +/- 11.1%, 39.7 +/- 8.9%, respectively, however, the difference was not significant, 1-yr survival in the patients treated with MCMP was 91 +/- 8.7%. It was postulated that long-term survival or cure can only be anticipated if the treatments giving high CR rates was developed. The study, though preliminary, supports the notion that MCMP therapy should be used as primary standard treatment for patients with multiple myeloma.

The role of continuous ambulatory peritoneal dialysis in end-stage renal failure due to multiple myeloma.
    American journal of kidney diseases : the official journal of the National Kidney Foundation, 1990, Volume: 16, Issue:3

    A study in 10 patients (eight male, two female; mean age 61.9 +/- 10.7 years) suffering from multiple myeloma (MM) and end-stage renal failure (ESRF) is detailed. Continuous ambulatory peritoneal dialysis (CAPD) was the preferred mode of chronic dialysis in all the patients. Survival after diagnosis was 32.2 +/- 23.9 months. Survival after starting dialysis was 24.6 +/- 20.6 months. All patients on CAPD were adequately dialyzed and in good fluid control. Peritonitis was the main problem on CAPD (one episode per 5.6 patient-months). The majority of peritonitis episodes responded to intraperitoneal antibiotic therapy. One patient with Staphylococcus aureus peritonitis, septicemia, and neutropenia secondary to chemotherapy, died. Recommendations for prophylaxis and treatment of peritonitis are given. Three patients were transferred to hemodialysis. The use of subclavian vein catheters during hemodialysis was associated with a high incidence of gram-positive septicemia. Alkylating agent-based chemotherapy resulted in hematological responses in five patients. Survival after diagnosis in those responders was 47.4 +/- 25.6 months, compared with 17.0 +/- 7.2 months in the nonresponders (P less than 0.05). All responders subsequently relapsed. Four patients died with progressive myeloma. Bone marrow suppression resulted in a high blood transfusion requirement, neutropenia, and thrombocytopenia associated with bleeding into the gastrointestinal tract and central nervous system. Uremic myeloma patients can be adequately dialyzed using CAPD. Those patients who do not have an initial hematological response have a poor prognosis.

Treatment of multiple myeloma by high dose chemotherapy, total body irradiation and autologous blood stem cell autograft.
    Nouvelle revue francaise d'hematologie, 1989, Volume: 31, Issue:2

    Fourteen patients with stage III aggressive multiple myeloma were treated by high dose chemotherapy (carmustine, etoposide and melphalan) and total body irradiation. This procedure was followed by autografting using blood stem cells previously collected by leukapheresis performed during recovery of cytotoxic drug-induced bone marrow aplasia. One patient died from cerebral bleeding at day 40. All other patients, including 9 whose disease was refractory to conventional treatments, achieved an impressive tumor mass reduction (over 90% in 12 cases). Two patients relapsed and died 12 and 15 months after the graft; another one relapsed but is still alive at 24 months. Two to 23 months (median 12 months) after the autograft, 10 patients are well either in apparent complete remission (2 cases) or with a state of stable minimal residual disease. Autologous blood-derived hematopoietic stem cells induced successful and sustained engraftment in the 13 evaluable patients. The cells collected by leukapheresis were studied for clonal Ig genes rearrangements indicative of circulating tumoral cells (or clonal B precursors) and none were found. Although preliminary, these results appear promising and high dose chemotherapy followed by autologous blood stem cell graft deserves consideration in young patients with multiple myeloma.

Intensive treatment of multiple myeloma and criteria for complete remission.
    Lancet (London, England), 1989, Oct-14, Volume: 2, Issue:8668

    50 previously untreated patients with multiple myeloma received two-phase treatment: repeated cycles of 4 day infusion with vincristine, doxorubicin, and methylprednisolone (VAMP) followed by high-dose melphalan (HDM), with autologous bone marrow transplantation where possible. The overall response rate was 74% (37/50), with 25 patients (50%) achieving complete haematological and biochemical remission. These remissions were associated with a good quality of life as measured by performance status, pain grade, and the reversal of humoral immunosuppression. 6 patients died during the VAMP phase and there was 1 death related to HDM. The achievement of complete remission, as defined here, in such a high proportion of patients is exceptional and may represent a useful advance in the management of myeloma.

    50 patients were treated for multiple myeloma with 5-drug combination chemotherapy between Jan 1979 and Feb 1980. After 8 years 12 patients (24%) were alive. The relative age-adjusted survival rate was 27%. The risk of death was constant during the follow-up, and active myelomatosis was still the main cause of death during the 8th yr. Thus the treatment is not curative. All 7 long-term survivors initially at stages II or III had at least a 75% response to the primary treatment. The other 5 patients were initially in an early stage (I) of their disease. Acute leukaemia has developed in 2 patients.

Hypoparathyroidism during alpha-INF therapy in a patient with multiple myeloma.
    Journal of medicine, 1989, Volume: 20, Issue:5-6

    A 66 year-old woman with multiple myeloma developed hypoparathyroidism during combination chemotherapy with melphalan, prednisolone, and alpha-interferon (INF). Seven weeks after commencement of the therapy, the serum calcium (Ca) level decreased to 7.4 mg/dL, and the phosphorus (P) level increased to 7.2 mg/dL; parathyroid hormone (PTH) was at a critically low level. By 13 weeks after discontinuation of alpha-INF, the levels of Ca, P, and PTH had returned to normal values: 8.6 mg/dL, 4.5 mg/dL, and 310 pg/ml, respectively. These changes suggest a strong correlation between hypoparathyroidism and the administration of alpha-INF. Autoantibodies against the parathyroid gland cell were not present in the serum of this patient by indirect immunofluorescent techniques. The mechanism of hypoparathyroidism by alpha-INF could not be identified, but this is the first case of this condition during alpha-INF therapy.

High serum levels of lactic dehydrogenase identify a high-grade lymphoma-like myeloma.
    Annals of internal medicine, 1989, Apr-01, Volume: 110, Issue:7

    Although conferring a grave prognosis in patients with malignant lymphoma, high levels of serum lactic dehydrogenase (LDH) are usually not seen in patients with multiple myeloma, a more indolent tumor composed mainly of B cells in their terminal stage of differentiation. Thus, only 2 of 118 patients in earlier phases of myeloma showed marked LDH elevations to more than 500 U/L, whereas such abnormalities were present in 12 of 64 patients with advanced disease progressing despite treatment with vincristine, doxorubicin (Adriamycin), dexamethasone (VAD) (median LDH level, 700 U/L). High LDH levels were associated with high serum levels of beta-2-microglobulin, hypercalcemia, extraosseous disease features, a short preceding clinical course as well as a short subsequent survival time. A poor prognosis was also noted in patients with lower LDH in whom marked increments were induced by high-dose chemotherapy; thus, LDH elevations to greater than 300 U/L present before or found after high-dose cytotoxic therapy were observed in about 50% of patients with VAD-resistant myeloma and define a new clinical entity with features of extraosseous disease and an unusually aggressive course ("high-grade myeloma"). The shorter survival of newly diagnosed patients with high-normal compared with those with low-normal LDH levels (less than 200 U/L), regardless of tumor mass, suggests the presence in some patients of a tumor subpopulation with high LDH production that escapes growth control with standard treatment. Staging of multiple myeloma should therefore include measurements of serum LDH levels in addition to beta-2-microglobulin analysis and tumor mass estimation.

Autologous bone marrow transplantation therapy for multiple myeloma.
    European journal of haematology. Supplementum, 1989, Volume: 51

    We have begun an autologous bone marrow transplantation (ABMT) treatment protocol for patients with myeloma who achieve a minimal disease (less than 10% marrow plasma cells) status. Sites of bony disease are irradiated before BMT. Melphalan 70 mg/m2 on days 1 and 2 is followed by 1200 rads total-body irradiation administered in fractionated doses over 3 d. Autologous marrow which has been previously treated with anti-CALLA, B1, and PCA-1 monoclonal antibodies is then thawed and reinfused. 4 males and 2 females with median age of 46 yr (41-56) have been treated. Granulocytes greater than 500/mm3 and platelets greater than 20,000/mm3 were noted at 21 (12-46) and 23 (12-53) d post-transplant (PT), respectively. Acute mucositis and dermatomal Herpes zoster developed in 3 patients each; all patients are clinically well at 233 (30-807) d PT. All patients achieved pathologically normal marrows, but monoclonal plasma cells and marrow myelofibrosis were each noted in a single patient at 486 and 272 d PT, respectively. A single patient has responded to alpha 2 interferon therapy PT; all others have received no therapy. AMBT offers an exciting new treatment for myeloma; however, relapses post-ABMT suggest that improved ablative regimens and/or marrow purging methods may be required.

Spinal cord compression in myelomatosis: response to chemotherapy alone.
    European journal of cancer & clinical oncology, 1989, Volume: 25, Issue:2

    Current management of spinal cord compression due to multiple myeloma usually involves irradiation with or without decompressive surgery. We report five patients (three of whom were severely affected) with a neurological deficit due to spinal cord compression by multiple myeloma, who regained ambulation and sphincter control with melphalan and prednisone alone. The dramatic response in these cases, as well as other evidence presented, suggests that systemic treatment may have a major role in the management of spinal cord compression by sensitive malignant tumours.

Acute myelomonoblastic leukemia in a patient with multiple myeloma.
    Acta medica Iugoslavica, 1989, Volume: 43, Issue:1

    A 40-year-old man who developed acute myelomonoblastic leukemia (M4) after 7 years of treatment for multiple myeloma with the alkylating agent melphalan and steroids is presented. Leukemia was treated with courses of adriblastin, cytosine arabinoside, and thioguanin (DAT protocol), with a 8 months' survival.

[Myelomatosis. A study of 138 patients treated with melphalan, prednisone and vincristine with particular attention to the prognostic value of a stage subdivision].
    Ugeskrift for laeger, 1989, Mar-27, Volume: 151, Issue:13

    With the object of evaluating three recognized prognostic stage subdivision systems for myelomatosis, retrospective data from 138 patients treated from 1976 to 1986 were employed. During this period, uniform therapeutic principles were employed, viz interval treatment with melphalan and prednisone supplemented, in cases of anaemia or raised serum creatinine, with vincristine. The prognostic significance for survival was calculated from variables at the time of diagnosis. The major prognostic factors were: age, tumour cell mass assessed by plasma cell percentage in the bone-marrow aspirate and/or M-component concentration, demonstration of Bence-Jones protein, renal function and the haemoglobin and calcium concentrations in the blood. Stage subdivision according the principles established by the Medical Research Council based on haemoglobin concentration and renal function were the best for assessing the prognosis in treated patients. Autopsy was performed on 55 out of the 96 patients who had died. The commonest cause of death was infection (75%).

Hemibody irradiation. An effective second-line therapy in drug-resistance multiple myeloma.
    Cancer, 1989, Jun-15, Volume: 63, Issue:12

    The authors report the results of treatment of 41 patients with melphalan-resistant multiple myeloma using single half-body irradiation (HBI) or double half-body irradiation (DHBI). Patients were grouped using prognostic classification reported by the Medical Research Council. Patients in group I and II showed the best response to therapy with reduction in serum of urinary paraprotein and improvement in symptoms, most notably a marked reduction in bone pain. In these groups five patients have survived over 2 years after therapy. The therapeutic response appeared better in those patients who received DHBI as opposed to those whom treated with single HBI. Patients in group III did not achieve prolonged survival but effective relief of bone pain was a consistent finding in these patients also. Thus HBI represents an alternative to combination chemotherapy as second-line treatment of patients with melphalan-resistant multiple myeloma. A comparative study of HBI versus combination chemotherapy is now indicated to establish which therapeutic approach is most effective.

Pharmacokinetics of oral melphalan in relation to renal function in multiple myeloma patients.
    European journal of cancer & clinical oncology, 1989, Volume: 25, Issue:5

    The impact of renal function on oral melphalan pharmacokinetics was studied in 15 patients with multiple myeloma. A two-fold interindividual variation in the plasma concentration-time curve (AUC) was found. An increase in AUC and melphalan mean residence time (MRT) was noted in patients with renal dysfunction. No correlation was found between GFR and the terminal plasma half-life time. We conclude from these results that renal dysfunction is associated with an increase in AUC and MRT of oral melphalan. A careful follow-up of hematological toxicity and possibly a dose reduction of melphalan are proposed for myeloma patients with renal impairment.

Glutathione and glutathione S-transferases in a human plasma cell line resistant to melphalan.
    Biochemical pharmacology, 1989, Jun-15, Volume: 38, Issue:12

    We report the development of a melphalan-resistant HS-Sultan human plasma cell line. The melphalan-resistant [MEL(R)] cell line was 16.7-fold more resistant to melphalan in vitro than the parent cell line [MEL(S)]. The wild type and MEL(R) HS-Sultan cell lines formed localized plasmacytomas when injected into nude mice. A dose-response effect of melphalan against the drug-sensitive plasmacytomas was present in vivo. A dose of 10 mg/kg of melphalan, which caused a 90% regression of MEL(S) plasmacytomas, had no effect on the MEL(R) plasmacytomas in vivo. In contrast to previous reports, there was no increase in the levels of glutathione (GSH) in the MEL(S) and MEL(R) plasmacytomas, suggesting that the association of elevated glutathione levels and melphalan resistance may not be common to all drug-resistant lines. In the MEL(R) plasmacytomas, there was a 1.5-fold induction of a pi type glutathione S-transferase (GST) as evidenced by isoelectric focusing (IEF) and Western blotting. This GST isoenzyme was purified and, although immunochemically similar to the pi type isoenzymes induced in other drug-resistant cell lines, was noted to have different functional characteristics. These data suggest that, depending on cell type and the drug studied, functionally different GST isoenzymes may be induced and they could be of importance in the development of drug resistance.

Oral melphalan pharmacokinetics--relation to dose in patients with multiple myeloma.
    Medical oncology and tumor pharmacotherapy, 1989, Volume: 6, Issue:2

    The pharmacokinetics of melphalan have been studied after oral doses of 5, 10 and 20 mg, and 10 mg i.v. Seven patients with multiple myeloma received the drug on 4 consecutive days and the concentration of melphalan was determined by liquid chromatography. Melphalan was rapidly absorbed after p.o. administration. Absorption lag-time was less than 1 h. The median time for attaining the peak concentration was 1.12 h (97% confidence interval: 0.68-1.55), 1.21 h (0.85-1.43) and 1.08 h (0.84-1.29) after doses of 5, 10 and 20 mg. The bioavailability showed large interindividual variations, and was not significantly affected by the dose given. There was a significant decrease in bioavailability during the treatment course (P less than 0.05). Absorption of melphalan obeys first-order kinetics in the dose interval studied. The results indicate that it might be of benefit to administrate oral melphalan for fewer days than the usually used 4 day regimen, in an attempt to achieve a higher bioavailability.

Etoposide, dexamethasone, cytarabine, and cisplatin in vincristine, doxorubicin, and dexamethasone-refractory myeloma.
    Journal of clinical oncology : official journal of the American Society of Clinical Oncology, 1989, Volume: 7, Issue:10

    Based on remarkable activity in refractory lymphomas, a combination of etoposide, cisplatin (both administered by 4-day continuous infusions), cytarabine (Ara-C), and dexamethasone (EDAP) was evaluated in 20 patients with advanced myeloma refractory to standard melphalan and prednisone (MP) and/or vincristine, Adriamycin (doxorubicin; Adria Laboratories, Columbus, OH), and dexamethasone (VAD) and even to high doses of melphalan (HDM) (seven patients). Forty percent of patients responded regardless of previously recognized risk factors (eg, duration of drug resistance, tumor mass, and serum lactic dehydrogenase [LDH] level). While the median survival was only 4.5 months, patients with good performance (Zubrod less than 2) and low or intermediate tumor stage survived more than 14 months compared with only 2 months for the remaining group. EDAP could be readily administered in the outpatient clinic, but neutropenic fever prompted hospital admission in 80% of patients, half of whom developed penumonia and sepsis, a fatal outcome in four patients. Severe myelosuppression was of short duration, so that subsequent cycles could be administered every 3 to 4 weeks. No serious extramedullary toxicity, including renal toxicity, was encountered. Marrow toxicity and hence infectious complications may be reduced by elimination of Ara-C without compromising treatment efficacy. We conclude that the lack of cross-resistance with VAD and even HDM makes EDAP or a similar combination an attractive regiment to be formally explored in an alternating sequence with VAD in high-risk myeloma.

[Multiple myeloma following chronic neutrophilia terminated with acute monocytic leukemia (AML, M 5 b)].
    [Rinsho ketsueki] The Japanese journal of clinical hematology, 1989, Volume: 30, Issue:6

    A case of a 70 years old female who developed multiple myeloma during a course of neutrophilia, and later on terminated with acute monocytic leukemia (AML, M 5 b) following Melphalan therapy for five years is reported. This patient was first found to have neutrophilia in 1966, After six years, she developed monoclonal gammopathy, (IgG1 kappa type) which coexisted with the neutrophilia. She was put on Melphalan regimen for 5 years which was discontinued due to anemia, leukocytopenia and the reduction of serum IgG. By routine bone marrow examination, she was diagnosed as AMoL (AML, M 5 b) in July 1984. Thereafter, a combination chemotherapy of BH-AC, 6-MP and prednisolone was started and complete remission for the AMoL was achieved after 2 months. Sixteen months later, she relapsed and a similar combination chemotherapy for reinduction regimen was administered. However, the AMoL was resistant and after 7 months, she died of pneumonia and multiple organ failure. The association of neutrophilia with multiple myeloma, the occurrence of AMoL after prolonged Melphalan therapy for the multiple myeloma and the strategy of therapy for secondary leukemia is discussed.

[Successful treatment of secondary erythroleukemia with androgen].
    [Rinsho ketsueki] The Japanese journal of clinical hematology, 1989, Volume: 30, Issue:7

    A case of secondary erythroleukemia treated with apparent success with androgen is reported. The patient is 63-year-old Japanese female. She had a history of multiple myeloma and had been treated with melphalan, vincristine and prednisolone. She developed erythroleukemia 88 months after the initiation of chemotherapy, while her myeloma was a complete remission. She was treated first with vitamin D3 with no beneficial effect and subsequently with 0.5 mg/kg of mepitiostane. A hematologic improvement began two months from the initiation of androgen therapy, and a complete remission of erythroleukemia was attained thereafter. A chromosomal abnormality of bone marrow cells, which was observed at the time of developing erythroleukemia, also disappeared after the treatment. She remained in good condition and hematologic remission under the androgen therapy at the latest follow-up, 1-year after the development of erythroleukemia. Androgen therapy may be considered as a useful treatment for secondary erythroleukemia.

Relevance of the hydrolysis and protein binding of melphalan to the treatment of multiple myeloma.
    Cancer chemotherapy and pharmacology, 1989, Volume: 23, Issue:2

    Experiments to determine the hydrolysis and protein binding of melphalan (L-phenylalanine mustard, L-PAM) were carried out in vitro for therapeutic concentration of the drug: the decrease in L-PAM concentration in plasma and whole blood during 24 h incubation at 37 degrees C was only 5% due to hydrolysis. Serum protein binding was about 90%, whereby 60% and 20% of this binding was due to interactions with albumin and acid alpha 1-glycoprotein, respectively. Immunoglobulins did not participate in the binding of L-PAM. The covalently bound part of L-PAM in serum was 30% in the concentration range of 1-30 micrograms/ml. The binding of dihydroxymelphalan (DOH) in serum did not exceed 20%. Glucocorticoids used in combination with L-PAM for treating multiple myeloma did not influence its protein binding. Our study with 35 sera from 15 patients with multiple myeloma shows that high levels of paraproteins do not increase but may decrease the binding of L-PAM, resulting in an elevated concentration of free drug.

In vitro studies of ways to overcome resistance to VAMP--high dose melphalan in the treatment of multiple myeloma.
    British journal of haematology, 1989, Volume: 71, Issue:2

    Myeloma colonies (MY-CFUc) from 7/24 patients undergoing treatment with VAMP (vincristine, adriamycin and methyl prednisolone) and high dose melphalan (HDM) were melphalan-resistant. It was not possible to conclude that VAMP induced melphalan resistance in MY-CFUc, but that resistance is endogenous in some myeloma cell populations. In 12/13 of the same patients of whom four had MY-CFUc which were melphalan resistant, the sensitivity of MY-CFUc and GM-CFUc to busulphan was similar. Thus resistance of MY-CFUc to melphalan did not confer resistance to busulphan. MY-CFUc from 1/7 of a second group of patients were adriamycin-resistant. This resistance was removed when the cells were treated with a combination of verapamil (3 micrograms/ml) and adriamycin. Verapamil also enhanced the toxicity of adriamycin to MY-CFUc from two patients where there was no evidence for adriamycin resistance. In these three patients the sensitivity of both MY-CFUc and GM-CFUc was similar after treatment with verapamil. Verapamil did not affect the uptake or efflux of 3H-daunorubicin in sensitive and resistant RPMI-8226 cells (myeloma) and peripheral blood mononuclear cells from a normal donor; neither did it affect the binding of 3H-daunorubicin to nucleic acid. It is concluded that verapamil may be a useful adjuvant to VAMP chemotherapy and that busulphan may provide an alternative to melphalan in patients whose myeloma cells are melphalan resistant.

Intermediate-dose (25 mg/m2) intravenous melphalan for patients with multiple myeloma in relapse or refractory to standard treatment.
    European journal of haematology, 1989, Volume: 42, Issue:3

    Intermediate-dose (25 mg/m2) intravenous melphalan has been evaluated in 34 multiple myeloma patients refractory to standard chemotherapies. The median time from diagnosis to entering of patients into the study was 27 months (range 7-71 months). A response was obtained in 12/34 patients (35%). 4 of 12 responding patients have relapsed and 2 of these have died; 8 responders have not relapsed and are still alive. The median duration of survival after 28 months of follow-up has not yet been reached in the group of patients responding to treatment. However, the overall median duration of survival for the 34 patients entered into the study was 8 months. The median duration of response was 16 months. Toxicity was limited to leukopenia, thrombocytopenia, nausea and vomiting. This lack of severe toxicity allowed us to administer the drug on an outpatient basis. The response rate and the low toxicity observed in this group of patients are encouraging and suggest that intermediate-dose intravenous melphalan is an effective and safe second line treatment for patients with multiple myeloma not responding to conventional treatment.

Combination chemotherapy for multiple myeloma with melphalan, ifosfamide, prednisolone, nitrosourea and vincristine.
    Acta medica Okayama, 1988, Volume: 42, Issue:3

    Melphalan, ifosfamide, prednisolone, nitrosourea [1-(4-amino-2-methyl-5-pyrimidyl)-3-(2-chloroethyl)-3-nitrosourea hydrochloride, ACNU or 1, 3-bis (2-chloroethyl)-1-nitrosourea, BCNU] and vincristine (MIP-NV) were given in combination to 48 patients with multiple myeloma. The response rate was 57% in previously untreated patients, and 39% in previously treated patients. The median survival time of previously untreated patients in stage IA + IIA was 49 months, and that of patients in stage IIIA + B was 27 months. The median survival time of stage III patients depended significantly on the duration of remission. The duration of remission and survival time of patients with relief of pain and improvement in daily activity were significantly longer than those of patients without such effects. Age, sex, blood hemoglobin concentration and bone lesion were important prognostic factors. As for the side effects, leukopenia (less than 1,000/microliter) and thrombocytopenia (less than 5 X 10(4)/microliter) occurred in 10.4% and 2.1% of the patients, respectively. It was concluded that multiple drug combination therapy with MIP-NV (MIP-NV therapy) was effective for patients with multiple myeloma at all clinical stages, because it resulted in long survival with low toxicity.

IgD multiple myeloma: a cure at 21 years.

    A 52-year-old man with a plasmacytoma of the body of T-10 in February 1965 returned 6 months later with multiple myeloma characterized by bone pain, osteolytic lesions, and IgD lambda monoclonal protein in the serum, 6.1 g of Bence Jones protein in the urine, and 21% plasma cells in the bone marrow. The M-protein and bone pain disappeared within 6 weeks after therapy with melphalan and prednisone was started. Therapy was discontinued in December 1974. Immunoelectrophoreses and immunofixations of the serum and urine over the years revealed no monoclonal protein. A mediastinal tumor developed, and the patient died of respiratory insufficiency on October 23, 1986. Autopsy revealed a large bronchogenic carcinoma of the right lung extending to the mediastinum, trachea, and esophagus. There was no evidence of multiple myeloma. This patient had responded rapidly to chemotherapy and had no recurrence of myeloma during a 21-year follow-up.

The pharmacokinetics of melphalan during intermittent therapy of multiple myeloma.
    European journal of clinical pharmacology, 1988, Volume: 35, Issue:2

    During intermittent melphalan-prednisone therapy the area under the plasma concentration-time curve of melphalan increased by an average of 45% after oral or intravenous administration of the drug in myeloma patients during the initial three courses at six-week intervals. The rise in melphalan plasma concentrations could not be referred to an alteration in melphalan elimination, metabolism, erythrocyte/plasma partition ratio, or protein binding. A possible explanation could be that covalent binding sites of melphalan were successively saturated during intermittent treatment, resulting in higher drug concentrations during successive courses of therapy.

Prognostic factors with high-dose melphalan for refractory multiple myeloma.
    Blood, 1988, Volume: 72, Issue:6

    High doses of melphalan (HDM) and dexamethasone were administered to 43 patients with advanced multiple myeloma, 36 of whom were refractory to both standard melphalan-prednisone and vincristine-adriamycin-dexamethasone (VAD). Forty-four percent responded with greater than 75% reduction in calculated tumor mass, including three patients who achieved a complete remission. The response rate to HDM was 56% in 18 relapsing patients and 50% in 12 patients with less than 12 months of primary drug resistance, but it was only 23% among the remaining 13 unresponsive patients. A high early mortality rate of 30% was confined to 26 patients with either poor performance (Zubrod greater than 1) or impaired renal function (creatinine greater than 1.4 mg%). When this toxic treatment was given to the 21 patients with good performance (Zubrod less than 2) whose disease lacked high serum lactic dehydrogenase (less than or equal to 500 U/L) as a recently recognized feature of high-grade myeloma, a superior median survival of 18 months was obtained as opposed to only 3 months for the 22 remaining patients (P less than .001). Thus, when employed in a timely fashion, HDM overcomes resistance to standard chemotherapy and VAD and benefits selected patients with advanced myeloma.

M-protein kinetics in multiple myeloma treated with melphalan, ifosfamide, prednisolone, nitrosourea and vincristine in combination.
    Acta medica Okayama, 1988, Volume: 42, Issue:5

    Patients with multiple myeloma were treated chemotherapeutically with a combination of melphalan, ifosfamide, prednisolone, nitrosourea and vincristine (MIP-NV therapy). The M-protein kinetics during the course of MIP-NV therapy was studied. The kinetics of serum and urinary M-protein in the first cycle of the chemotherapy was classified into four patterns, and the mode of change in the M-protein level over the entire course of chemotherapy was classified into four prototypes. There were intimate relationships among M-protein kinetics patterns in the first cycle of the chemotherapy, the effect of the chemotherapy on M-protein reduction, maturity of myeloma cells, pretreatment labeling index and clinical stage of the disease. Moreover, analyzing the prototypes, it was found that both the time for maximum M-protein reduction and the rate of increase in the M-protein level after maximum M-protein reduction affected the survival time. To predict the effect of the chemotherapy on M-protein reduction and survival time, it was useful to analyze subgroups, which were classified according to the M-protein kinetics pattern in the first cycle, the time for maximum M-protein reduction and the rate of increase in the M-protein level after maximum M-protein reduction.

Early plasma cell recruitment in multiple myeloma following chemotherapy.
    Cell and tissue kinetics, 1988, Volume: 21, Issue:6

    Therapy-induced modifications of bone marrow plasma cell kinetics were studied in three patients with myelomatosis. The investigation was performed prior to and 15 d after termination of a course of aggressive chemotherapy. An increase in the labelling index (40-212% of pretreatment values) with a corresponding reduction of Ts (5-34%) was observed in all cases. As a consequence of this combined variation, the fractional turnover rate (which represents the percentage of cells produced per unit time) was the parameter with the highest increment (54-276%). These results indicate that plasma cell recruitment occurs soon after chemotherapy and is characterized by a shorter S phase and a higher number of DNA-synthesizing cells.

M-2 protocol for melphalan-resistant and relapsing multiple myeloma.
    European journal of haematology, 1988, Volume: 40, Issue:2

    33 patients with advanced refractory multiple myeloma received a combination of vincristine, cyclophosphamide, carmustine, melphalan and steroids (M-2 protocol). 20 of them had failed prior chemotherapy with alkylating agents and the remaining 13 patients had relapsed after a response to these drugs. An objective tumour cell mass reduction (greater than or equal to 50%) was achieved in 17% of the patients (6% of previously nonresponders and 33% of previously relapsing), while 9 additional patients improved (30-50% tumour reduction), for an overall response rate of 47% (39% for previously nonresponders and 58% for previously relapsing). The median duration of response was 7 months. Thrombocytopenia was the most common toxicity encountered in the study (39% of cases). Our findings indicate that M-2 protocol is an effective salvage treatment for patients who relapse from previous chemotherapy with alkylating agents. In contrast, results in patients who are primarily resistant to these drugs justify the search for different treatment programmes which can produce greater degrees of tumour reduction.

VBAMDex chemotherapy in advanced multiple myeloma.
    European journal of haematology, 1988, Volume: 40, Issue:3

    In a phase II study 28 patients with advanced multiple myeloma were treated with a five drug regimen consisting of vincristine, BCNU, adriamycin, melphalan and dexamethasone. 11 out of 13 patients without prior chemotherapy showed significant remissions (greater than 25% tumor cells mass reduction), 7 of them had more than 75% TCM reduction. Out of 15 additional patients resistant to previous chemotherapy, 13 had significant remissions, including 9 patients with greater than 75% TCM reduction. No tumor progression was observed in either group of patients. The median follow-up of all patients was 12.75 months. 4 patients relapsed. Toxicity mainly related to the bone marrow was observed in 14 patients. This regimen might offer a promising alternative for the treatment of advanced multiple myeloma, but still has to be tested in a prospective randomized trial.

Dose intensity analysis of melphalan and prednisone in multiple myeloma.
    Journal of the National Cancer Institute, 1988, May-18, Volume: 80, Issue:6

    The average relative dose intensity (DI) of conventional oral melphalan and prednisone therapy received by 93 newly diagnosed multiple myeloma patients was correlated with survival and with percent reduction in M-protein. A survival advantage was shown with increasing average relative DI of melphalan and prednisone. Multivariate analysis showed survival to correlate with increasing DI of prednisone (P = .05) but not with the DI of melphalan (P = .93) nor with the percent decrement in M-protein (P = .10). These results suggest that the initial management of myeloma should be reassessed, with particular emphasis on more intensive therapy employing high-dose steroids.

Multiple myeloma of the serosa coat.
    Journal of cancer research and clinical oncology, 1988, Volume: 114, Issue:3

    We report on a 47-year-old male patient with IgA-kappa plasmacytoma, who 12 months subsequent to diagnosis developed marked ascites. On light and electron microscopy morphologically identical plasma cells with bizarre intracytoplasmatic material were found in the bone marrow, pleural exudate, and ascites fluid. This kind of extramedullary spread is extremely rare and usually resists therapy. The mean survival rate for the 9 patients with malignant plasmacellular ascites whose cases have been documented so far was 2 months. After progression under VCMP regimens our patient has been successfully treated over a period of more than 4 years with i.v. VP16 monotherapy with additional intermittent local administration of methotrexate and systemic poly-chemotherapy according to the VAD scheme.

A simple method for culturing myeloma cells from human bone marrow aspirates and peripheral blood in vitro.
    British journal of haematology, 1988, Volume: 69, Issue:2

    A double layer agar technique has been developed to grow myeloma colonies (MY-CFUc) from human bone marrow aspirates and peripheral blood. Heavily irradiated HL60 cells (5 x 10(5)/plate) are added to an agar underlay in growth medium containing 0.5% agar. Mononuclear cells from the test bone marrow or blood are overlayered in either 0.2 ml HL60-conditioned medium (HL60-CM) or in 0.5 ml growth medium containing 0.23% agar, and the cultures are incubated at 37 degrees C in an atmosphere of 5% CO2, 10% O2 and 85% N2. Colonies (greater than 50 cells) form between 2 and 3 weeks. Using this method 60/68 samples of bone marrow and 7/12 samples of blood from 54 patients have produced colonies in soft agar and in liquid on an agar underlay. The cells which form these colonies are of two distinct sizes, the larger cells being plasmacytoid and the smaller lymphoid. The two cell types are usually, but not always, present in separate colonies. Both plasmacytoid and lymphoid cells carry the isotype of the respective patient's myeloma protein and the plasma cell marker (HAN PC1). This technique has enabled us to culture myeloma cells from patients with as few as 2% plasma cells in the bone marrow but it does not permit the growth of normal B, T or granulocyte-macrophage colonies (GM-CFUc). The drug sensitivity of myeloma cells (MY-CFUc) compared with normal haemopoietic cells (GM-CFUc) can be measured using dose-response curves in individual patients. Furthermore, this method can detect resistant subpopulations within a given myeloma sample.

[A case of multiple myeloma responding very well to the combination of K18 with prednisolone].
    Gan to kagaku ryoho. Cancer & chemotherapy, 1987, Volume: 14, Issue:4

    A case of multiple myeloma refractory to various anticancer drugs was effectively treated with the combination of K 18 with prednisolone, which led to a remarkable decrease of serum M-protein and overall recovery. In 8 months of the treatment, although slight bone marrow suppression was noted, no severe side effect was observed. The patient has survived for more than one year in remission. We suggest that the combination of K18 with prednisolone may be effective for multiple myeloma which is unresponsive to treatment with anticancer drugs.

[Heterogenicity of the response to chemotherapy in plasmablastic myeloma].
    Nouvelle revue francaise d'hematologie, 1987, Volume: 29, Issue:6

    Several recent studies have identified in multiple myeloma a plasmablastic subgroup characterized by its very sombre prognostic. We report the results of treatment in 10 high risk patients with plasmablastic myeloma stage IIIA in the Durie and Salmon classification, stage III in the Bartl classification (tumoral mass greater than 50%). The median survival of the 10 patients was 8 months. These patients, who were resistant to melphalan-prednisone (M-P) or to VMCP in conventional doses, fell into 2 categories: those who responded to chemotherapy with adriamycin, and those who resisted all types of chemotherapy from the start. The finding of such heterogeneous responses to chemotherapy in the plasmablastic subgroup of multiple myeloma and the usefulness of CALLA+ antigen determination make it necessary to study cell differentiation antigens, which would in the long term alter the therapeutic approach in these patients.

Short course intermediate dose intravenous melphalan therapy in myeloma--relation to early emergence of drug resistance (phase II study).
    Acta haematologica, 1987, Volume: 78, Issue:4

    Intermediate dose intravenous melphalan at a dose of 15 mg/m2 x 4 given at 21-day intervals has been evaluated in 20 consecutive patients. The aims were to assess the time to obtain maximal response, duration of response and response to reintroduction of intravenous melphalan on relapse. Median time to maximal response was 17 weeks. Four patients achieved a complete response with complete disappearance of paraprotein. On relapse, reintroduction of intravenous melphalan was unsuccessful in causing a reduction of paraprotein, suggesting that resistance to this dose of melphalan occurs early even in responding patients.

Biology and therapy of multiple myeloma.
    Acta haematologica, 1987, Volume: 78 Suppl 1

    Bone marrow plasma cells of patients with myeloma are frequently aneuploid, have a high RNA content and typically show monoclonal immunoglobulin in their cytoplasm. Kappa-lambda co-expression in aneuploid tumor cells was restricted to patients with IgG lambda myeloma. Immunophenotype studies revealed early B cell expression often in association with mature B cell markers. Chromosomal aberrations were complex with a predominance of numeric but also structural lymphoma-type translocations; the latter were most prevalent in IgA myeloma. Specific translocations such as t(8;14) and t(11;14) were accompanied by aberrations of c-myc and bcl-l cellular genes. Effective salvage programs have been developed for melphalan-prednisone refractory myeloma. In comparing high-dose dexamethasone with vincristine-adriamycin + dexamethasone (VAD), VAD was superior particularly for relapsing myeloma (response rate of 60 vs. 23%). For VAD refractory myeloma, high-dose melphalan (HDM) programs were developed; total body irradiation (850 rad) followed by HDM 140 mg/m2 and supported by autologous bone marrow grafts was particularly effective and relatively well tolerated with all 4 patients still in remission from 3 to 15 months.

High-dose chemoradiotherapy and autologous bone marrow transplantation for resistant multiple myeloma.
    Blood, 1987, Volume: 70, Issue:3

    Seven patients with advanced multiple myeloma, refractory to therapy with alkylating agent-VAD (vincristine-adriamycin-dexamethasone), received a regimen combining high-dose melphalan with total body irradiation supported by autologous bone marrow transplantation. Very rapid, usually greater than 90% tumor mass reduction was achieved in six patients, regardless of prior chemotherapy responsiveness and marrow plasmacytosis up to 30%. Despite signs of early relapse in three patients (median remission duration of all patients, 15 months), five remain alive and well without further cytotoxic therapy from 2 to 21 months (median, 9+ months). Two patients died, one from surgical complications after transplantation and a second due to persistent neutropenia with fatal pneumonia. This treatment provides meaningful disease control for selected patients with resistant myeloma and a poor prognosis.

    Schweizerische medizinische Wochenschrift, 1987, Feb-21, Volume: 117, Issue:8

    Since the beginning of the seventies there have been an increasing number of reports of second malignancies in patients treated with cytotoxic agents. The commonest of these malignancies are acute nonlymphocytic leukemias. Such occurrences are also known in patients with multiple myeloma treated with melphalan. In a 74-year-old female with multiple myeloma treated with melphalan for 19 months, erythroleukemia developed 23 months after the start of treatment. The second malignancy has almost entirely displaced the myeloma cells in the marrow. In consequence, the paraprotein gradient in electrophoresis diminished in size.

Three cases of secondary leukemia. Clinicopathologic findings.
    Acta pathologica japonica, 1987, Volume: 37, Issue:5

    Three cases of secondary leukemia developing after chemotherapy and/or radiotherapy for myeloma, mycosis fungoides, and non-Hodgkin's lymphoma are reported. The first case was a 51-year-old man with IgG-lambda myeloma, treated with melphalan and prednisolone, who developed acute myelomonocytic leukemia 54 months after the diagnosis of myeloma. The second case was a 54-year-old woman with mycosis fungoides treated with radiation, predonine, and cyclophosphamide, who developed acute megakaryoblastic leukemia 298 months after the diagnosis of mycosis fungoides. The third case was a 35-year-old woman with stage IV non-Hodgkin's lymphoma treated with VEMP who developed acute myelogenous leukemia 26 months after the diagnosis of malignant lymphoma. All cases showed pancytopenia and two of three cases had morphologic abnormality in several hemopoietic cell lineages in the leukemic stage. There is a possibility that second malignancies are an increasingly recognized complication in the patients treated with a large amount of chemo-radiotherapy.

    Six patients with multiple myeloma were treated with HLBI-MP regimen; HLBI 300 X 10(4)U/day daily, Melphalan 4 mg/day p.o. from day 1 to 4 and prednisolone 20 mg/day p.o. from day 1 to 4. Two patients had been refractory to a combination chemotherapy consisting of vincristine, cyclophosphamide, prednisolone and/or adriamycin, while the other 4 patients had been previously untreated. With the HLBI-MP regimen, 3 of 6 patients showed clinical effects. Among the two patients previously treated, one showed an improvement in performance status and the other disappearance of plasmacytoma, respectively. One previously untreated patient showed more than 50% reduction of M-protein. Slight to moderate leukocytopenia was found in all cases, but this was controlled without need for cessation of HLBI. HLBI-MP regimen is thus expected to be useful in the clinical management of patients with multiple myeloma.

Multiple myeloma treated with high dose intravenous melphalan.
    British journal of haematology, 1987, Volume: 66, Issue:1

    High dose melphalan (HDM, 140 mg/m2 i.v.) has been evaluated in 58 patients under 63 years with multiple myeloma. Among previously untreated patients 11/41 (27%) entered a complete remission (CR: no measurable myeloma protein and a normal bone marrow) and 21 (51%) entered a partial remission (more than 50% reduction in myeloma protein and improvement in all other features). Median duration of remission is 19 months. Two patients who had responded to previous conventional treatment entered CR after HDM. Among 15 patients who had failed on previous chemotherapy the response rate was 66% including two CRs. However, in this group all patients have relapsed within 1 year. Profound myelosuppression, moderate nausea, vomiting, mucositis and diarrhoea with reversible alopecia occurred in all patients. There were 10 deaths within 2 months of treatment mainly due to sepsis and haemorrhage. In a subsequent study, high dose methyl prednisolone (1 g/m2 daily for 5 d) has been added to HDM. Response rates are similar with 6/22 (27%) CR, 13/22 (59%) PR and 2/22 NR but there was only one early death, reflecting improvements in medical management. The high CR rate is an encouraging feature of this approach which is now to be the basis of a prospective trial sponsored by the Medical Research Council in which HDM, with and without steroids, is compared to the best available conventional therapy (the MRC VI Myelomatosis trial).

Interferon alfa-2b/melphalan/prednisone in previously untreated patients with multiple myeloma: a phase I-II trial.
    Investigational new drugs, 1987, Volume: 5 Suppl

    Interferon alfa-2b (Intron A; Schering Plough) has been shown to be active in advanced previously treated multiple myeloma (MM). Recent in vitro evidence has suggested synergy between cytotoxic agents and interferon alfa-2b. This phase I-II protocol was initiated to study interferon alfa-2b in combination with melphalan and prednisone. Groups of five patients received interferon alfa-2b twice-weekly for two weeks at dose levels of 0.5, 1.0, 2.0, 5.0 and 10.0 X 10(6) IU/m2. During week 2, melphalan (9 mg/m2) and prednisone (40 mg/m2) were administered concurrently with interferon alfa-2b followed by a rest period during nadir myelosuppression, the cycles being repeated every 28 days. Thirty patients were entered of whom 21 were Stage III, 3 Stage II and 6 Stage I. Median nadir WBC/mm3 and platelets/mm3 at the various dose levels are given in the table. Serious adverse reactions while on study included myocardial infarction, renal failure and leukopenia-related sepsis. Early response information is available. Twenty-six patients are evaluable for response. Seven have had progressive disease and 19 (69%) a partial response, the median duration was 11+ months. Interferon alfa-2b does not appear to antagonize melphalan/prednisone effectiveness and may be additive or synergistic. Full evaluation of this combination will be undertaken in randomized controlled trials which are now underway.

Are the current criteria for response useful in the management of multiple myeloma?
    Journal of clinical oncology : official journal of the American Society of Clinical Oncology, 1987, Volume: 5, Issue:9

    One hundred seventy-three patients with multiple myeloma were treated from the time of diagnosis with standard oral melphalan and prednisone at 28-day intervals until they became refractory to treatment. Response to treatment was determined according to the Chronic Leukemia-Myeloma Task Force (TF) criteria, and independently according to the Southwest Oncology Group (SWOG) criteria. Survival by disease stage and response according to the two sets of criteria were analyzed for patients living longer than 3 months. The median survival of responding and nonresponding (TF criteria) stage II patients was 43.8 and 40.3 months, respectively (P = .29). By SWOG criteria, median survival for responding and nonresponding stage II patients was 48.3 and 39.0 months, respectively (P = .12). In stage III patients, median survival for responders and nonresponders (TF criteria) was 34.0 and 21.7 months, respectively (P = .01), compared with 35.5 and 24.4 months (P = .04) by SWOG criteria. These data would suggest that the TF criteria predicts a survival disadvantage only in very advanced myeloma and that applying the stricter limits for the definition of response of the SWOG does not further aid in selecting a subgroup of myeloma patients with poorer survival.

Weekly cyclophosphamide and alternate-day prednisone: an effective secondary therapy in multiple myeloma.
    Cancer treatment reports, 1987, Volume: 71, Issue:10

    Intravenous or oral cyclophosphamide, 150-250 mg/m2 (500 mg maximum), once per week with alternate-day oral prednisone, 100 mg, was given to 57 myeloma patients resistant to melphalan and prednisone (MP). Seven responses in 28 primary MP-resistant patients and ten responses in 29 secondary MP-resistant patients were observed. Previous response to MP was not a significant factor in predicting response to weekly cyclophosphamide and alternate-day prednisone. The results suggest that the regimen of weekly cyclophosphamide and alternate-day prednisone may be as effective as more aggressive regimens in the treatment of patients with myeloma who have failed MP therapy. However, a randomized trial would be required to determine the relative contributions of cyclophosphamide and prednisone to the effectiveness of this regimen.

Impaired chemiluminescence response by neutrophils in patients with multiple myeloma.
    Scandinavian journal of haematology, 1986, Volume: 37, Issue:4

    Neutrophil chemiluminescence (CL) as a measure of oxygen-dependent killing activity was evaluated in 3 groups of patients: (a) 63 patients with multiple myeloma (MM); (b) 31 subjects with monoclonal gammopathy of undetermined significance (MGUS); (c) 32 healthy controls. Neutrophil CL response was shown to be significant reduced both in patients with MM (p less than 0.001) and in subjects with MGUS (p less than 0.001). A significant difference was also observed between the results obtained in MM and those of MGUS (p less than 0.001). Treated MM patients showed a more severe impairment of neutrophil chemiluminescence response than that observed in untreated patients (p less than 0.001). It is suggested that the impairment of neutrophil CL response, possibly related to decreased killing activity, may play a role, along with other known causes, in the increased susceptibility to infection observed in MM patients.

    K 18, an IgG-Melphalan conjugate was administered to 30 patients, who had recurrent hematopoietic malignancy. Ten out of the 30 patients received single doses of 1 to 20 enteric tablets containing 10 mg of K 18, as a phase I study. No side effects were observed. K 18 was administered every day to the remaining 20 patients in order to evaluate the side effects and therapeutic effects, as a phase II study. One patient attained partial remission. Although no remission effect was obtained in 14 of the 20 patients, antitumor effects such as a decrease in leukemia cells, were observed in 4 of 20 patients. As to side effects, neither recurrence of tumor nor cumulative toxicity were shown in one patient with NHL who received only K 18 for 14 months as maintenance therapy. Evaluation of antitumor effect was difficult in the case of the remaining 4 patients. In the 20 cases who entered the phase II study, a decrease in neutrophils was observed in 2 patients, a slight decrease in platelets in 3 patients and increased transaminase activity in one patient as side effects of K 18. In brief, compared with Melphalan, K 18 has between 1.3 and 2 times a more potent therapeutic effect, with extremely low side effects.

High-dose melphalan with autologous bone marrow transplantation for multiple myeloma.
    Blood, 1986, Volume: 67, Issue:5

    A large dose of melphalan was given to 23 patients with advanced multiple myeloma that was refractory to multiple prior treatments. Sixteen patients received a dose of 80 to 100 mg/m2, and seven were given 140 mg/m2 followed by autologous bone marrow infusion. Tumor mass was reduced by more than 75% in 14 patients, including four who died of bone marrow aplasia. Serious infections were prevented in six of seven patients who received autologous bone marrow. The marked cytoreduction in patients with previously refractory disease indicated the apparent drug resistance could be overcome by dose escalation. However, short remission times in most responding patients were consistent with rapid regrowth of primordial tumor cells with high proliferative activity. Although high-dose melphalan was of limited benefit to patients with refractory myeloma, further studies are necessary to clarify its role during earlier phases of disease.

BCNU (5.5 mg/kg, in a single dose) and total body irradiation (10 Gy in a single fraction) we observed in all 3 cases the disappearance both of serum M component and of monoclonal bone marrow plasma cells. 1 patient died of acute GVH disease, grade IV, at 2 months, while the other 2 patients are in good health and in unmaintained complete remission at 4 and 20 months, respectively. The usefulness of allogeneic bone marrow transplantation in the management of multiple myeloma is emphasized.

Therapy of primary resistant and relapsed multiple myeloma.
    Onkologie, 1986, Volume: 9, Issue:4

    This article reports the efficacy of two salvage programs for primary resistant and relapsed multiple myeloma. Employing high dose dexamethasone alone or combined with continuous infusions of vincristine and adriamycin (VAD) in 83 patients, 1/3 achieved a greater than or equal to 75% tumor cytoreduction. The highest response rate of 65% was observed among previously responding patients receiving VAD compared to approximately 1/4 among those receiving VAD for primary resistant disease or dexamethasone alone regardless of prior response status. Tumor halving times were short with values of 0.5 months for VAD and 1.3 months for dexamethasone alone. The single most important pretreatment variable associated with failure to achieve remission was a low RNA content of myeloma plasma cells in the bone marrow. The second program evaluated high dose melphalan with or without autologous bone marrow transplantation in 23 patients resistant to VAD salvage treatment. Ten of 23 patients responded for at least 2 months, and 4 others had a comparable anti-tumor effect but died between 4-6 weeks from disseminated infection. Unlike the VAD regimen, responses occurred regardless of prior response or plasma cell RNA content, and tumor halving times were extremely short with a median of 0.3 months. With autologous bone marrow support, the higher melphalan dose (140 vs. 100 mg/m2) could be more safely administered to an older patient population (median of 63 vs. 44 years) with 1 of 7 vs 6 of 16 drug-related deaths in the absence of marrow support.(ABSTRACT TRUNCATED AT 250 WORDS)

Alpha-2-interferon/melphalan/prednisone in previously untreated patients with multiple myeloma: a phase I-II trial.
    Cancer treatment reports, 1986, Volume: 70, Issue:4

    Alpha-2-interferon (IFN) has demonstrable activity in advanced, relapsing, or refractory multiple myeloma. Because of the in vitro synergism between the IFNs and cytotoxic agents, we conducted a trial of 30 previously untreated patients with multiple myeloma utilizing various doses of alpha-2-IFN in combination with standard oral doses of melphalan and prednisone. The combination was well-tolerated without unusual or unexpected toxic effects. The limiting toxicity included dose-related myelosuppression, and alpha-2-IFN induced flu-like symptoms and fatigue. Response was seen in at least as many patients as would be expected with melphalan and prednisone alone. The maximal tolerated dose for a phase II-III trial was 5.0 X 10(6) IU/m2 of alpha-2-IFN in combination with standard doses of melphalan and prednisone. Future trials should utilize this dose of alpha-2-IFN with dose de-escalation according to tolerance.

Renal function in the elimination of oral melphalan in patients with multiple myeloma.
    Cancer chemotherapy and pharmacology, 1986, Volume: 17, Issue:2

    Pharmacokinetic studies in 11 patients with multiple myeloma were undertaken on the first and last days of one course of chemotherapy. The drug was administered PO in single doses of 6-14 mg daily. Melphalan concentrations were determined by high-performance liquid chromatography. The interpatient variability of pharmacokinetic parameters noted by other authors was observed. Regression analysis showed a significant positive correlation between the elimination rate constant for melphalan and renal function (P = 0.003). The form of the line which describes the overall elimination rate constant for melphalan is given by the equation: Kel = 5.67 X 10(-3) + [4.90 X 10(-5) X GFR]. There was also a significant negative correlation between renal function and the area under the plasma melphalan concentration/time curve (P = 0.006). In vitro stability studies of melphalan in plasma at 37 degrees C and pharmacokinetic data suggest that hydrolysis and renal clearance are the major mechanisms of melphalan elimination. This work shows quantitatively the relationship between renal function and drug elimination and how the data may be used in predicting melphalan half-life from creatinine clearance.

Prognostic factors for multiple myeloma in the dog.
    Journal of the American Veterinary Medical Association, 1986, Jun-01, Volume: 188, Issue:11

    Multiple myeloma was diagnosed in 60 dogs. Diagnosis was confirmed in each case by observation of greater than 5% plasma cells on examination of a bone marrow aspirate and detection of monoclonal gammopathy of immunoglobulin (Ig) A or IgG. Treatment with melphalan, cyclophosphamide, and prednisone was associated with long-term survival (median, 540 days). Response to therapy was significantly related to prognosis (P less than 0.01), whereas hypercalcemia and Ig light chain proteinuria (Bence Jones) were associated with shorter median survival times.

[Interstitial pneumopathy caused by melphalan].
    Revue des maladies respiratoires, 1986, Volume: 3, Issue:2

    The Authors have described a case of interstitial pneumonia due to 1-phenyl alanine (Melphalan). This case report, where a diagnosis of myeloma of the lung was excluded, was characterised by contact with a single cytotoxic agent in low doses and a short delay before the appearance of the pneumopathy. The different cytotoxic substances capable of inducing such pulmonary lesions are recalled as well as the mechanisms responsible for the phenomenon. The Authors compare their observations to the 5 well documented cases in the literature and suggest that hypersensitivity may have been a contributory factor in their case.

Renal failure in multiple myeloma. A study of the presenting findings, response to treatment and prognosis in 26 patients.
    Nouvelle revue francaise d'hematologie, 1986, Volume: 28, Issue:3

    The presenting clinical features, response to treatment and survival duration of 26 consecutive multiple myeloma patients with renal failure at diagnosis were investigated. All but 1 of the patients had high tumour cell mass stage, as identified by one (3 cases) or more (22 cases) of the criteria defined by Durie and Salmon. Survival length of azotaemic patients was significantly shorter than that of stage III patients with normal renal function (median: 4 months vs 41 months, respectively, P less than 0.0005), and was positively affected by reversal of renal failure following treatment (P less than 0.0005). Of the 26 patients, 56% achieved reversal of renal failure. Recovery of normal renal function was prompt in most of the cases and appeared to be independent from both M component type and pretreatment serum creatinine levels. Finally, it was shown that patients with reversible renal impairment but with myeloma unresponsive to alkylating agents had early recurrence of impaired renal function and a shorter life expectancy than patients with a significant decrease in tumour cell mass.

    Deutsche medizinische Wochenschrift (1946), 1986, May-30, Volume: 111, Issue:22

    99 patients with multiple myeloma were treated over a period of 6 1/2 years; 62 of these were initially treated with vincristine, carmustine, cyclophosphamide, melphalan and prednisone: M 2-Protocol. Response to this therapy was assessed after three therapy cycles had been completed, which had been given at intervals of 5-6 weeks. In patients responding to the therapy, treatment was continued until a maximum regression of the paraproteins was achieved. By the end of May 1985, the data of 52 patients could be evaluated, in 31 (60%) of whom remission was observed. Median survival time of all patients was 27 months. In 18 patients with "complete" remission the median has not yet been reached after 40 months. In 13 patients with partial remission, the median survival time was 36 months. In patients with complete remission, the median remission period was 26.5 months, in patients with partial remission 13.9 months.

Interferons in the treatment of multiple myeloma.
    Seminars in oncology, 1986, Volume: 13, Issue:3 Suppl 2

    Recombinant DNA technology has made adequate quantities of human interferons available for both in vitro and in vivo testing. In the clonogenic assay, RPMI-8226 myeloma cells were tested with recombinant interferon alfa-2b (Intron A), melphalan, cyclophosphamide, and prednisone. Prednisone used as a single agent had the least cytotoxic effect. Concentrations of alfa-2b as low as 1 unit/mL (international antiviral activity) showed a reduction in colony number of less than 30% of the untreated controlled cultures. Melphalan and cyclophosphamide showed measurable cytotoxic activity, expressed in terms of 50% inhibition of colony growth, at doses of 0.15 microgram/mL and 0.4 microgram/mL, respectively. Additive antiproliferative effects were noted with combinations of alfa-2b plus cyclophosphamide and alfa-2b plus prednisone. However, the alfa-2b-melphalan combination had a synergistic effect on tumor-cell colony reduction. Even greater cytotoxic activity was seen with the three-drug combination of alfa-2b, melphalan, and prednisone. Clinical trials have shown that alfa-2b may be effective in patients with relapsing and refractory multiple myeloma. Of 38 patients evaluated, seven responded to treatment. Three of the seven responders have continued to respond for over 33 months, with monoclonal proteins approaching undetectable levels. A pilot study of the feasibility of combining alfa-2b with melphalan and prednisone in previously untreated patients with multiple myeloma has been completed. Although response was not the primary objective of this study, an overall response rate of 78% was achieved using criteria established by the Chronic Leukemia Task Force. Phase II trials conducted thus far have established tumor responsiveness to interferons in human myeloma. To clearly define the role of these agents in the treatment of myeloma, well-planned multicenter studies are needed.

Peptichemio in pretreated patients with plasmacell neoplasms.
    European journal of cancer & clinical oncology, 1986, Volume: 22, Issue:9

    Twenty-one patients with alkylator-resistant plasmacell neoplasms were treated with Peptichemio (PTC) at a dose of 40 mg/m2 for 3 days every 3 weeks or, in the case of persistent leukopenia and/or thrombocytopenia, at the single dose of 70 mg/m2 every 2-3 weeks according to haematological recovery. Seventeen patients, 10 with multiple myeloma and seven with extramedullary plasmacytoma (EMP), were fully evaluable. Six of 17 patients (35%) responded: three of seven EMP patients had a complete remission and 3 of 10 multiple myeloma patients had an objective response greater than 50%. The median duration of response was 8.5 months. An EMP patient obtained a complete response lasting for 16 months. The most frequent toxic effect were phlebosclerosis, occurring in all the patients, and myelosuppression, which was severe in only one case. PTC appears to be an active drug in patients with plasmacell neoplasms even if resistant to alkylating agents.

    In 12 of 18 patients with multiple myeloma refractory to treatment with the combination of vincristine, melphalan, cyclophosphamide, and prednisone, favorable results were obtained by replacing vincristine in this combination with vindesine. Although only three patients showed marked reductions (greater than 50%) of myeloma protein, this treatment, which was well tolerated, was also clearly beneficial to the other responding patients, thus postponing the need for more toxic treatment programs.

Multiple myeloma masquerading as metastatic breast cancer.

    Two women are described in whom, on the basis of prior therapy for breast cancer and the presence of painful, lytic bone lesions, an initial diagnosis of metastatic breast cancer was made. Further evaluation established the diagnosis of multiple myeloma in both patients. Neither had evidence of recurrent breast cancer. These cases indicate that women with a history of breast cancer in whom lytic bone lesions develop without evidence of extraskeletal metastases should have the diagnosis of multiple myeloma excluded.

Melphalan-resistant multiple myeloma: results of treatment according to the M-2 protocol.
    Cancer chemotherapy and pharmacology, 1985, Volume: 14, Issue:3

    A group of 46 patients with melphalan-resistant multiple myeloma was treated according to the M-2 protocol with melphalan, prednisolone, BCNU, cyclophosphamide, and vincristine. According to the Salmon and Durie classification, four patients had stage II A; 36, stage III A; and six, stage III B disease. Treatment resulted in five patients (11%) entering remission, while 21 (46%) had stable and 20 (43%) had progressive disease. The median survival for all patients was 12.5 months, patients in remission surviving longer (median 46 months) than those with stable disease (median 15.4 months) or progressive disease (median 6.9 months). Compared with other treatment regimens used in melphalan-resistant myeloma, the remission rate is low but the median survival exceeds that reported by most other authors.

    Adherence to the dose or the need for dose reduction and the duration of treatment intervals were determined retrospectively for 1446 chemotherapy courses in 291 patients with malignant lymphoma and breast cancer. In patients over 60 years of age treated with the COP and COPP regimes there was a significantly higher frequency of deviation from the standard regime than in younger patients; a similar situation was seen in patients with breast cancer. The cause in the elderly patients was presumably due to the higher incidence of non-oncological diseases. In a group treated using the CHOP-scheme there was no difference in comparison with the reference group. In this group patients with severe pre-existent diseases were excluded before treatment. The results indicate that age itself is not a major risk factor for a combination chemotherapy. Pre-existent diseases play a substantial role in the toxicity of cytostatics.

    54 consecutively referred, previously untreated patients with stage II and III multiple myeloma have been treated with the M-2 protocol. 50% of patients had a performance status of less than 50%. 13% were stage II and 87% stage III. In 50 of 54 patients (90%), and objective response according to the Myeloma Task Force was achieved; 10% of the responses have been complete (9+, 15+, 17+, 18+ and 66+ months). Remissions now range from 1 to 86+ months. The actuarial median survival determined from the initiation of therapy will exceed 4 years. Toxicity was acceptable with mild myelosuppression. These results confirm the efficacy of the M-2 protocol in multiple myeloma with regards to response rate and survival.

Monitoring myeloma: light chain isotype suppression. A new parameter.
    Australian and New Zealand journal of medicine, 1985, Volume: 15, Issue:5

    Optimal therapy in patients with multiple myeloma relies on methods which indicate stability or progression of disease. At present, patients are assessed by monitoring the myeloma M-component in the serum and the urinary light chain excretion levels, or by calculating the myeloma cell mass. However, clinical disease activity does not always correlate with changes in these indices. Recent studies suggest that monitoring the expression of light chain isotypes on peripheral blood lymphocytes may provide evidence of progressive disease before clinical deterioration. Stable plateau phase disease has been shown to be associated with suppression of the expression, on peripheral blood lymphocytes, of the light chain isotype concordant with the malignant paraprotein. Loss of this suppression has been associated with active disease.

    A patient with IgG3 lambda plasma cell myeloma characterized by anemia, hypercalcemia, hypoalbuminemia, renal insufficiency, osteolytic bone lesions, and serum and urinary light chains inadvertently received a dose of intravenous melphalan considerably greater than standard. A complete remission ensued characterized by normal protein and bone marrow studies. Healing of bone lesions occurred. This and two somewhat similar happenstances producing rare complete remissions in myeloma may have significant chemotherapeutic ramifications.

    A 71-year-old woman with multiple myeloma was successfully managed for 8 years with melphalan (total dose 2056 mg). She developed a refractory anemia (myelodysplastic state), which terminated in acute eosinophilic leukemia. This form of acute leukemia, induced by chemotherapy, appears to be very rare. The cytogenetic changes, including 5q- and monosomy 7, were similar to those observed in other patients with acute nonlymphocytic leukemia as a secondary malignancy following treatments of other primary tumors.

Chylomicronaemia in multiple myeloma.
    Scandinavian journal of haematology, 1985, Volume: 34, Issue:5

    A patient with multiple myeloma presented with an accumulation of chylomicron-like particles. This rare finding resembled that of the type V hyperlipoproteinaemia phenotype. The lipid and lipoprotein concentration and composition were compared with values obtained from other patients with multiple myeloma, patients with the type V hyperlipoproteinaemia phenotype (accumulation of chylomicrons and very low density lipoproteins), and normal subjects. An immunoglobulin-lipid complex was demonstrated in our patient. This complex was found not to be associated with the chylomicrons and was detected only in the lipoprotein-deficient plasma. Lipid and lipoprotein concentration and composition differed from the other groups. Very low density lipoprotein concentration was reduced, and there was thus a marked difference from the type V phenotype. The chylomicrons derived from this patient were also richer in apolipoprotein C compared to chylomicrons derived from the patients with type V hypolipoproteinaemia. It appears that the abnormal composition of the triglyceride-rich lipoproteins observed in this patient renders her refractory to the normal pathways of metabolism.

Rate of M-component changes and plasma cell labeling index in 25 patients with multiple myeloma treated with peptichemio.
    Cancer treatment reports, 1985, Volume: 69, Issue:9

    Twenty-five consecutive patients with previously untreated multiple myeloma were studied for bone marrow plasma cell labeling index, response to peptichemio induction therapy, and rate of M-component (MC) changes during the course of the disease. They received intermittent melphalan or cyclophosphamide as maintenance therapy and peptichemio associated with vincristine at first relapse. The response rate (76%) was independent of clinical stage, evaluated according to Merlini et al and to Durie and Salmon. Among responsive patients, rapid responders (half-life of MC decrease less than 47 days for IgA and IgG and less than 29 days for light chain myelomas) had a bone marrow plasma cell labeling index significantly higher (P less than 0.01) than that of slow responders. Rapid responders had a median survival of 15 months, while slow responders had a median survival of 42 months (P less than 0.05). The difference in survival between the two groups was accounted for mainly by the difference in duration of first response and the different rates of MC increase following it. Both of these parameters were directly related to the half-life of MC decrease at response in IgA and IgG myelomas. The duration of second response and the half-life of MC increase following it were shorter than the duration of first response and than the half-life of MC increase at first relapse.

[High life expectancy in multiple myeloma].
    Terapevticheskii arkhiv, 1985, Volume: 57, Issue:7

    The authors describe the main clinicolaboratory finding of 9 patients with multiple myeloma (MM) who survived 10 and more years. The number of the "long-lived" survivors among 256 patients with MM seen from 1966 to 1980 amounted to 3.5%. The main characteristics of the disease of the "long-lived" survivors were correlated to those of 247 MM patients who survived for less than 10 years. In principle, no differences were revealed between the compared groups in term of the size of the initial tumor mass, red blood, and the degree of osteolysis. It was established that the 10-year and higher survival was observed in relatively young people without signs of renal insufficiency, who responded well to the cytostatic treatment. In 8 out of the 9 survivors, a long-term remission was attained by combining sarcolysine and prednisolone. The median survival rate for the entire group amounted to 25 months, that for the "long-lived" survivors to 133 months. In the authors' opinion, an unusually high survival rate among MM patients cannot be only attributed to successful cytostatic therapy. Among the 247 MM patients, 60% responded to the treatment fairly well. However, only 3.5% of the patients survived over 10 years. The prognosis of MM is likely to be determined by some individual features of the tumor and by the patients' antitumor defence mechanisms.

[Possibility of complete recovery in multiple myeloma].
    Terapevticheskii arkhiv, 1985, Volume: 57, Issue:7

    In three patients with multiple myeloma, stage IIIA, a complete remission lasting from 6 to 8 years was attained, in spite of the fact that not all of them received treatment. In the latter case the remission lasted from 5 to 6 years. One of the patients had diffuse Gk + BIk myeloma, one presented with multiple focal one with protein BIk production, and one patient had multiple focal myeloma with spinal cord compression and complete lower paraplegia without verified secretion of monoclonal immunoglobulin. The times of therapy until the attainment of a complete remission were 3,5 and 13 years, whereas the total survival amounted to 9, 5 and 20 years since the appearance of the first disease symptoms. Sarcolysine was employed as the basic cytostatic agent in all the cases. Annual control examinations of the patients in a state of remission have not revealed any signs of myeloma. One patient is manifesting osteolytic deficiencies, however biopsy withdrawn from the focus of osteolysis have not shown any tumor. Immunochemical assay of serum and urine has failed to detect paraprotein, blood immunoglobulins have been discovered to be within normal. The author analyses 4 similar cases reported in literature. It is assumed that it would be premature to regard the patients described above as completely recovered from the biological standpoint and that it would be more wise to consider such cases as prolonged and fairly profound remissions.

Therapy related acute non-lymphocytic leukemia: report of 4 cases.
    The Southeast Asian journal of tropical medicine and public health, 1985, Volume: 16, Issue:3

    Four cases of acute myelodysplastic-non-lymphocytic leukemia secondary to cytotoxic agents were reported. Primary diseases were breast cancer (1 patient), ovarian cancer (2 patients) and multiple myeloma (1 patient). All except one (with multiple myeloma) were in clinical remission of their primary diseases. Common cytotoxic agent used was melphalan. Median total drug dose and median latent period from diagnosis of primary diseases were 1299 mg and 63 months respectively. None with the exception of one received specific treatment. All died except one who is in a very poor condition. Survival from the diagnosis of hematologic diseases ranged from 3-9 months. Clinical features, cytogenetic findings, pathogenetic mechanism and risk of the disease were briefly discussed.

Peripheral neuropathy in osteosclerotic myeloma: clinical and electrodiagnostic improvement with chemotherapy.
    Muscle & nerve, 1984, Volume: 7, Issue:2

    A patient with a severe remote-effect polyneuropathy and other paraneoplastic features of osteosclerotic myeloma improved dramatically with melphalan and prednisone treatment. Serial electrodiagnostic studies provided an objective means of following the response to therapy and documented the improvement. We believe this represents the first reported patient with multifocal osteosclerotic myeloma and a myelomatous polyneuropathy responding to melphalan and prednisone.

    Onkologie, 1984, Volume: 7, Issue:3

    A 44 year old man with kappa-light plasmacytoma is presented who had been treated for osteoporosis and multiple bone fractures since 12 years. On admittance he had a rapidly progressive myeloma kidney and an extensive extramedullary tumor within the pelvis. Remission was induced using combination chemotherapy according to the VMCP-protocol. It is discussed that the long-lasting osteoporosis of the present case represents an unusually long, monosymptomatic early stage of a multiple myeloma rather than an independent primary disease.

    Scleromyxedema is an uncommon fibromucinous connective tissue disease characterized by accumulation of mucinous material in the dermis. A monoclonal paraprotein is regularly identified. A review of the literature (57 cases) shows the exceptional association of scleromyxedema with multiple myeloma (8.7%) and macroglobulinemia Waldenström (3.5%). A man with scleromyxedema, IgG lambda paraproteinemia, and sclerodactylia--as a special sign of scleromyxedema--is reported. Melphalan is the drug of choice in serious cases, but not effective in sclerodactylia.

    A patient who presented simultaneously with typical hairy cell leukaemia (HCL) and multiple myeloma (MM) is described. He was treated with melphalan and irradiation and 18 months later presented with an adenocarcinoma. The occurrence of multiple neoplasms in this patient may reflect an underlying predisposition to neoplasia secondary to the immunological defects common in B cell lymphoproliferative diseases.

Effective treatment of advanced multiple myeloma refractory to alkylating agents.
    The New England journal of medicine, 1984, May-24, Volume: 310, Issue:21

    Twenty-nine patients with advanced refractory multiple myeloma were treated with intermittent high-dose dexamethasone in combination with four-day infusions of vincristine and doxorubicin. Rapid and marked tumor-mass reduction (greater than 75 per cent) was noted in 14 of 20 patients whose disease was resistant to alkylating agents and in 3 of 9 patients with additional resistance to doxorubicin--a result far superior to those in previous trials with similar patients. In responsive patients, remissions were of excellent quality, and survival was significantly longer than in unresponsive patients.

    Deutsche medizinische Wochenschrift (1946), 1984, Jun-29, Volume: 109, Issue:26

    Melphalan and prednisolone were intermittently used for treatment of 101 patients with multiple myeloma. In case of progression, either initially or after remission or after a phase of stabilisation, treatment was changed to the M-2 protocol. By primary treatment, remission was obtained in 24 patients, a stable phase in 47 patients. The treatment of second choice which became necessary in a total of 46 patients led to remission in 5 patients (11%), 21 (46%) became stabilised and in 20 (43%) the disease progressed. The median survival time for all 101 patients was 40.5 months after commencement of treatment. In patients with remission it was clearly longer (67 months) than in those with stable disease (38.1 months) or in those with progression (16.8 months). The mean time of survival after commencement of treatment of second choice was 12.5 months. Compared to other studies the remission rates are slight, the time of survival, however, is very remarkable. The overall survival rates are equivalent to the results thus far obtained by more aggressive treatment schemes.

Efficacy of the M-2 protocol in previously untreated patients with advanced multiple myeloma.
    Blut, 1984, Volume: 49, Issue:5

    37 consecutive, previously untreated patients with advanced multiple myeloma (16 patients Stage II, 21 patients Stage III) were treated with a five drug regimen consisting of carmustine, melphalan, vincristine, cyclophosphamide and prednisolone (M-2-protocol) in a prospective manner. Remission was achieved in 24 patients (65%). The median time to remission was 10 weeks, the median duration of remission 15,3 months. Median survival time from the onset of treatment was 24 months for all patients. Responding patients have a projected 65% three year survival. Median survival in non-responders was 10 months. 8 patients died during the first year of treatment. These results do not confirm the favourable results with this drug combination obtained in a previous trial. The discrepancy may be explained by a higher proportion of poor risk patients in the present study.

Distribution of SCEs in lymphocytes in persons with normal, slightly increased, and heavily increased SCEs.
    Mutation research, 1984, Volume: 125, Issue:2

    The distribution of SCEs in lymphocytes was examined for 165 healthy persons (58 non-smokers and 107 smokers with cigarette consumption ranging from 1 to greater than 20 per day), and for 1 patient treated with melphalan, a cytostatic drug. The data from the healthy persons did not follow a Poisson distribution. A mixed Poisson that allowed different lambda values for the 30 cells scored from each person and postulated a gamma distribution for the lambda s within the 30 cells fitted all the data examined including those from the melphalan-treated patient. In the latter case the 7 samples taken at various times after the treatment could all be represented satisfactorily with a common parameter, c, in the gamma distribution for the lambda s, even though the mean SCEs/cell varied from 9.8 to 36.8. Because the c parameter determines the spread of lambda values within the 30 cells, this suggested that the effect of the cytostatic drug was to increase all the lambda s by a constant amount. The sum of the SCEs taken over all 30 cells in a sample is a convenient summary statistic, and the transformation y = square root s + square root s + 1 behaves as a normal variate with a constant variance within a group.

Long-term survival of a patient with multiple myeloma--a cure? A case report.
    Cancer, 1984, May-15, Volume: 53, Issue:10

    Multiple myeloma is a disease characterized by the proliferation of malignant plasma cells, the over-production of a monoclonal immunoglobulin (paraprotein) and the subsequent depression of the other normal immunoglobulins. Whereas many patients respond to treatment and enter a plateau phase of variable duration, these patients eventually die of their disease. This report describes a patient with Stage III multiple myeloma diagnosed in 1966 and now with documentation of prolonged disease-free survival and perhaps cure, with the patient presently alive and well without evidence of disease.

Comparison of the fed and fasting states on the absorption of melphalan in multiple myeloma.
    Cancer chemotherapy and pharmacology, 1984, Volume: 12, Issue:3

    Melphalan absorption was studied over three consecutive days in five patients with multiple myeloma. On 1 day melphalan (approximately 7 mg/m2 = 10-12 mg) was administered IV, on 1 day PO fasting, and on 1 day PO after a standard breakfast. The order was different for each patient to minimise trends that might affect absorption. Melphalan concentrations were determined by high-pressure liquid chromatography and fitted to biexponential equations by computer. The parameters of these equations were in broad agreement with previously published data, and melphalan absorption varied between patients. Considerable differences were observed in the melphalan concentration curves between the 'PO fed' and 'PO fasting' days: on the PO fed days the delay before absorption started was longer (1.1 +/- 0.5 h as against 0.3 +/- 0.1 h); peak plasma levels were one-third the value (65 +/- 15 ng/ml; 195 +/- 80 ng/ml) and occurred at twice the time after administration (2.8 +/- 0.8 h; 1.3 +/- 0.3 h); and areas under the curve were smaller 10.8 +/- 4.7 min X micrograms/ml; 23.8 +/- 13.8 min X micrograms/ml). There was a significant difference between the fraction of the dose of melphalan absorbed on the PO fed day (0.49 +/- 0.20) and on the PO fasting day (0.93 +/- 0.22), with P less than 0.005. This work suggests that melphalan should be taken first thing in the morning to obtain greatest absorption.

    The authors report the results of a prospective, multi-centre trial involving 87 patients with previously untreated myeloma who were treated by combination chemotherapy consisting of melphalan, cyclophosphamide, CCNU, prednisone and vincristine. 83.1% of patients had a high tumour mass (stage III on Durie and Salmon's classification). The response to treatment could be evaluated in 76 patients and 70% were found to respond. The median actuarial survival of the whole population is 30 months. The survival is significantly longer (p less than 0.001) in responders (median 40 months) than in non-responders (median: 17 months); the survival is significantly shorter (p less than 0.01) in subjects with renal failure (median: 10 months) than in subjects without renal failure (median: 36 months). This treatment is sufficiently well tolerated to be administered on an outpatient basis. One case of acute monoblastic leukaemia was observed. These results are similar to those reported in the literature.

    The results of a combination chemotherapy trial (melphalan, CCNU, vincristine, cyclophosphamide) involving 28 patients with stage III (n = 21) or stage II (n = 7) multiple myeloma suggest a high response rate, with a mean 71% malignant cell destruction in 78.5% of the patients. A longer survival in responsive stage III patients as compared with patients treated with alkylating agents seems likely, but this can only be established by a randomized trial. Despite haematological side-effects, this combination therapy may be used in high risk patients, especially those resistant to a single alkylating agent and in whom the frequency, intensity and duration of responses appears to be the same as in previously untreated patients. In contrast, only one of the 7 patients treated for relapse after previous response to a single alkylating agent responded to the combination chemotherapy.

Osteosclerotic myeloma and peripheral neuropathy.
    Neurology, 1983, Volume: 33, Issue:2

    Sixteen cases of osteosclerotic myeloma and peripheral neuropathy (SM-PN) were reviewed. The neuropathy resembled chronic inflammatory-demyelinating polyneuropathy with predominantly motor disability, high CSF protein levels, and low motor nerve conduction velocities. Twelve of the 16 patients had detectable levels of monoclonal serum proteins, all with lambda light chains, but results of other laboratory studies were usually normal. Most of the patients also had organomegaly, endocrine abnormalities, or both. Treatment of solitary lesions with tumoricidal irradiation usually improved the neuropathy and reversed the nonneurologic abnormalities; chemotherapy for multiple osteosclerotic lesions was less helpful.

Prognostic significance of pretreatment serum beta 2-microglobulin levels in multiple myeloma.
    European journal of cancer & clinical oncology, 1983, Volume: 19, Issue:10

    Pretreatment serum beta 2m levels were estimated in 65 patients with multiple myeloma. After correction for changes in renal function, the level of beta 2m attributable to multiple myeloma (beta 2m-m) no longer correlated with the serum creatinine, but showed a strong correlation with the total body myeloma cell mass (P = 0.002). There was an inverse correlation between beta 2m-m and the Karnofsky performance status of patients at presentation (P = 0.001). Patients with a pretreatment beta 2m-m level of less than the median value of 2.94 mg/l survived significantly longer than those with a raised level (P = 0.0008).

    Three patients with plasma cell leukemia are reported. Two of them has a previous history of myeloma; the third one started with a plasma cell leukemia. Diagnosis was made from the required presence of 20% plasma cells in the peripheral blood. In all 3 cases, bone marrow aspiration and peripheral blood showed plasma cells strongly positive for acid phosphatase and alpha-naphthyl acetate esterase, and negative for periodic acid-Schiff. The first patient was treated with a polychemotherapy regimen that included vincristine, cyclophosphamide, chlorambucil and prednisone, and the second patient with melphalan and prednisone; the third one, who started with plasma cell leukemia, received total body irradiation at the dose of 600 rad. The results of the therapy and survival time, which was never more than 3 months, are in accord with other reports in the literature.

Heavy chain loss after treatment with Melphalan in a patient with "nonsecretory" myeloma.
    Blut, 1983, Volume: 46, Issue:2

    A case of "nonsecretory" myeloma is described. The patient had typical osteolytic lesions and marked infiltration of myeloma cells in the bone marrow, and plasma cell leukemia. A good partial remission was obtained with Melphalan, but the patient relapsed and died one year later. Immunofluorescent and immunoelectroscopic studies on the myeloma cells demonstrated the presence of cytoplasmic gamma-and kappa-chains at the initial stage and of only kappa-chains at a relapse. The electron microscopic method for polysome analysis indicated that both L-and H-chains were synthesized on membrane-bound polysomes initially, but the ability to produce H-chain was missing at the relapse.

Long-term survival of patients with multiple myeloma and acute renal failure at presentation.
    American journal of kidney diseases : the official journal of the National Kidney Foundation, 1983, Volume: 2, Issue:5

    Eight patients presented with simultaneous multiple myeloma and acute renal failure requiring hemodialysis. Patients had no known pre-existing renal disease nor exposure to nephrotoxic agents or x-ray contrast dye. Renal failure was attributed to light chain nephropathy in all cases. In 4 of these patients the diagnosis of myeloma was initially unsuspected. Renal biopsies in 3 of these patients, and post-mortem material in a fourth revealed the changes of "myeloma kidney." No patient regained renal function and all required chronic hemodialysis. Among these eight patients, three survived for periods greater than 21 months.

Multiple myeloma with renal failure. A case for intensive treatment.
    Australian and New Zealand journal of medicine, 1983, Volume: 13, Issue:2

    A series of nine consecutive patients with multiple myeloma and renal failure is presented. All patients were treated with urinary alkalinisation with sodium bicarbonate and/or acetazolamide, diuresis with saline, mannitol and/or furosemide, pulse melphalan and prednisone and, where indicated, allopurinol and aluminium hydroxide. A substantial and sustained improvement in renal function has been achieved in all nine patients. Of five patients with a urea more than 25 mmol/L at presentation, the median survival to date is 64 weeks. Of these patients only one has died --not from renal failure but pneumonia, eighteen months after presentation. The others are alive and well. The results confirm the effectiveness of these measures in both improving renal function and prolonging survival, and suggest a more optimistic prognosis for patients with multiple myeloma and renal failure.

    Twenty patients with plasma cell myeloma were treated with high-dose (10 mg/kg) intermittent administration of cyclophosphamide for remission induction and maintenance therapy. High-dose intermittent administration of glucocorticosteroid hormone was also performed usually in parallel with large-dose of cyclophosphamide. A significant objective response was obtained in 12 of 20 patients (60.0%). The median survival was 32 months in all cases; 47 months in the responding cases. The response rate was not affected by the class of M-protein, the type of light-chain and/or the presence of bone lesions. All responders were on the 3rd stage. High-dose intermittent administration of cyclophosphamide was evaluated as very useful since it showed equivalent effects obtained by combination chemotherapy regimens, hardly producing bone marrow suppression.

[The osteocondensing variety of multiple myeloma. Review of the literature and description of a case].
    Minerva medica, 1983, Oct-27, Volume: 74, Issue:41

    A case of IgG myeloma with eburnation of the femoral and ileoischiopubic bones is described. A review of the literature confirmed the rarity of osteosclerotic myeloma, especially if other possible causes of bone eburnation or the typical contemporary existence of osteolysis are excluded. The hypothesis that osteosclerotic myeloma may constitute an autonomous form of the disease, probably related to the type and/or extent of the proliferating bone is discussed.

Prognostic value of bone marrow plasma cell infiltration in stage I multiple myeloma.
    British journal of haematology, 1983, Volume: 55, Issue:4

    We analysed for prognosis and response to chemotherapy a series of 48 consecutive stage I myeloma patients who were treated with melphalan and prednisone soon after diagnosis. It was found that the extent of bone marrow plasma cell infiltration had prognostic value, the survival of the patients with more than 50% plasma cells being significantly shorter (P less than 0.005) than that of the patients with less than 50% plasma cells. In the latter group, the observed number of deaths was so small (two cases) as to preclude any further analysis. In contrast, in the former group, a significant relationship between the response to chemotherapy and patients' survival (P less than 0.001) was demonstrated. We conclude that a prospective randomized trial of treatment versus no treatment is warranted in stage I patients who have a high risk of death (i.e. with a high bone marrow plasma cell infiltration) in order to establish whether chemotherapy prolongs the length of survival.

DNA content of human myeloma cells.
    European journal of cancer & clinical oncology, 1983, Volume: 19, Issue:1

    DNA flow cytofluorometry of bone marrow cells from 29 patients with multiple myeloma disclosed a 55% incidence of aneuploid cell populations with a DNA index between the diploid and the tetraploid regions (2-4 C) and a mean value of 2.5 C. The bone marrow of these patients demonstrated a correlation between the proportion of aneuploid and morphologically identifiable myeloma cells, which indicates a monoclonal pattern in the aneuploid cases without additional diploid myeloma cell clones. In the present patient material no statistically significant relation was found between diploid and aneuploid cases as regards the type of monoclonal immunoglobulin. Further, there was no difference between the diploid and aneuploid cases as regards myeloma cell differentiation, myeloma cell [3H]-thymidine labeling index or response to melphalan treatment.

Clinical staging and therapeutic results in multiple myeloma.
    European journal of cancer & clinical oncology, 1983, Volume: 19, Issue:10

    The validity of the Durie and Salmon's clinical staging system for multiple myeloma has been tested in 81 consecutive patients studied at the Istituto Nazionale Tumori of Milan from January 1970 to June 1982. Median survival from diagnosis was 48 months for stage I, 41 months for stage II and 23 months for stage III (P = 0.02). Median survival of patients with normal renal function (A) was 35 months and of those with abnormal kidney function (B) 7 months. Almost all early deaths were observed in patients with stage III disease associated with renal failure. No statistically significant difference was found in the median survival in patients with kappa and those with lambda light chains. The analysis of survival according to the three main combinations of chemotherapy used in this study (melphalan-prednisone vs melphalan-procarbazine-prednisone vs adriamycin-prednisone) could not disclose any significant difference. Prognosis was, however, closely related to the response to combination chemotherapy: median survival was 72 months in responders, 36 months in patients with improvement and 25 months in non-responders (P less than 0.01). A lower incidence of response was obtained in patients with stage III myeloma compared to patients with stage I-II. The myeloma staging system used in this study is simple to employ and allows identification of truly comparable patient groups in the evaluation of therapeutic results. Our therapeutic results confirm the effectiveness of melphalan plus prednisone and fail to demonstrate any advantage in the administration of adriamycin as first-line therapy.

Treatment of multiple myeloma with M-2 protocol and without maintenance therapy.
    European journal of cancer & clinical oncology, 1983, Volume: 19, Issue:10

    From September 1975 to December 1981, 63 consecutive untreated patients with multiple myeloma received the Lee M-2 protocol. We used the same drugs (melphalan, cyclophosphamide, vincristine, BCNU and prednisone) but employed the lowest suggested doses and recycled earlier, i.e. after 21-28 days. Thirty-five patients (62.5%) were in stage III, 16 (28.6%) in stage II and 5 (8.9%) in stage I. An objective response (reduction in paraprotein production rate greater than 50%) was obtained in 44 out of 56 cases (78%); 32 (57%) had a reduction greater than 75%. The median duration of response was 21.5 months. In responding patients the treatment was stopped after 1 yr and resumed only at relapse. Twenty-two out of 25 retreated patients are now evaluable. Eighteen of them (82%) responded again; in retreatment the degree of response was lower, but the duration of second response was only slightly lower than the first response (15.7 vs 21.5 months, NS). Of 7 patients receiving a third M-2 reinduction 4 responded again. The median survival for all the patients is 51 months. The high rate of second response to the M-2 regimen after an unmaintained remission brings into question the value of continuous therapy in responsive multiple myeloma.

    Zeitschrift fur die gesamte innere Medizin und ihre Grenzgebiete, 1983, Dec-01, Volume: 38, Issue:23

    62 patients with multiple myeloma were primarily treated with the combination vincristin + melphalan + cyclophosphamide + prednisolone (VMCP). In therapy failures and relapses, respectively, vincristin + cyclophosphamide + adriamycin + prednisolone (VCAP) were administered. Under primary treatment with VMCP in 28 patients (45%) remissions were obtained, in 22 patients (36%) incomplete remissions and 12 patients (19%) were estimated as therapy failures. The secondary application of VCAP increased the total number of the remissions to 32 (52%). Incomplete remissions and therapy failures more frequently appeared in the clinical stage III and in undifferentiated myelomas. The median survival time of the total group was 46 months. With more than 60 months patients with remission showed significantly larger median survival times than those ones with incomplete remission (14.5 months) and therapy failures (6 months), respectively.

Tumor proliferation and chemotherapy in immunosuppressed mice.
    Cancer research, 1983, Volume: 43, Issue:3

    The influences on host immunosuppression by treatment with cyclophosphamide (200 mg/kg), steroid (prednisolone, 12.0 mg/kg for seven doses or 235 mg/kg for one dose), and adult thymectomy on tumor growth were compared. Treatment with cyclophosphamide 24 hr prior to MOPC 104E tumor transplantation produced the greatest facilitation of tumor growth. The role of prednisolone in rendering the MOPC 104E cells more vulnerable to conventional chemotherapy was also investigated. The combination of prednisolone with melphalan added measurably to the cytotoxicity of the treatment and increased the percentage of disease-free survivors. The observed effects of prednisolone might have been due to the increase in the cycling of myeloma cells directly, or the drug may have facilitated growth of the myeloma by blocking host expansion of T-cell immunity. Alterations of the host by adult thymectomy and immunosuppression with cyclophosphamide or prednisolone led to growth facilitation of myeloma. The limited studies reported here point out the usefulness of facilitation of tumor growth to accomplish increased neoplastic cell kill and increased percentage of disease-free survivors.

[Therapy of multiple myeloma. Study of hospital patients: 81 cases in 16 years' observation].
    Minerva medica, 1983, Feb-11, Volume: 74, Issue:5

    The results achieved with different approaches of chemotherapy protocols applied to 81 patients affected by multiple mieloma and followed up for a duration of 16 years in the geographical area pertaining to the Saronno County Hospital are presented. All the patients are divided into sub-groups, according to the type of treatment they required while being monitored over the years. Each single sub-group is evaluated according to the following criteria: objective response to therapy; median survival rates; toxic effects due to drug exposure. The results are analyzed with reference to the most relevant literature on the matter. A comprehensive retrospective review of emerging data suggests an overlapping median survival--30 and 31 months--in patients given monochemotherapy as such as in those given polychemotherapy. Evidence is also made for a clearly meaningful increase of survival in treated patients compared with that of untreated ones. Median survival depends significantly on the initial stage of the disease. Both therapeutical effectiveness and toxicity are shown to be higher, in accordance with the current literature, in polychemotherapy which include vincristine--especially when a large tumor cell mass is pointed out--compared with therapy based on alkilating agents and prednisone.

    A case of myelodysplasia (refractory anaemia with excessive blasts) arising 7 years after a 3 year period of intermittent monthly treatment cycles with melphalan for multiple myelomas is reported. This is another example of preleukaemic syndrome possibly caused by melphalan. Among the possible pathogenetic mechanisms, the incidence of cyclic episodes of medullary hypoplasia are emphasised.

Cross-resistance to alkylating agents in multiple myeloma.
    Cancer, 1983, Sep-01, Volume: 52, Issue:5

    In order to ascertain whether multiple myeloma patients resistant to one alkylating agent would respond to a second one, high-dose intermittent cyclophosphamide was administered to 12 patients showing resistance to melphalan and prednisone. On the other hand, intermittent melphalan and prednisone treatment was employed in eight myeloma patients resistant to intermittent cyclophosphamide. Only one objective response was achieved among 12 patients on cyclophosphamide therapy, in spite of having employed high doses of this alkylating agent. No responses were achieved with melphalan in the group of cyclophosphamide-resistant patients. The median survival probability was 8.7 months (SD +/- 2.9) for all patients after starting the second alkylating agent. These results suggest cross-resistance between melphalan and cyclophosphamide in myeloma. The authors conclude that a single second alkylating agent cannot be recommended as a treatment of patients with multiple myeloma who are truly refractory to one alkylating agent.

Prednisone pulse therapy for refractory myeloma.
    Blood, 1983, Volume: 62, Issue:3

    The utility of vindesine and a frequent prednisone schedule was evaluated in 70 patients with refractory myeloma. No patient responded to vindesine alone, but about one-fourth achieved significant tumor reductions from intermittent high-dose prednisone, either alone or in combination with vindesine. Forty-seven percent responded when prednisone pulses were combined with vincristine and doxorubicin, providing the best results yet achieved in our patients with refractory myeloma. In responding patients, remissions were of excellent quality and survival was prolonged significantly. These results supported the utility of a more frequent corticosteroid schedule with increased doxorubicin dose in patients with advanced and resistant multiple myeloma.

Human myeloma: kinetics of the remission phase.
    Acta haematologica, 1982, Volume: 68, Issue:3

    The kinetics of myeloma cells at diagnosis and during complete remission were compared on 4 IgG K patients. We were able to study experimentally the kinetics of the minimal tumor mass because we prepared anti-idiotypic sera specifically directed against the hypervariable region of the M protein. We have shown that the residual myeloma cell labelling index during remission is usually lower than that observable on diagnosis. This finding conflicts with the current opinion on minimal tumor mass kinetics. Therefore, it is suggested that a new therapeutic strategy should be adopted in the complete remission phase.

    Acta medica Austriaca, 1982, Volume: 9, Issue:4

    Chemotherapy with alkylating agents and Prednisone can achieve a prolonged median survival time in patients with multiple myeloma which lasts as long as the remission endures. Aggressive therapeutic regimens could not achieve a further tumor cell reduction as soon as a stable phase is reached. Waldenström's macroglobulinemia requires a therapeutic approach, which is adjusted to the individual case. Patients with small tumor mass and therapy responders have a significant prolonged median survival time compared to patients with large tumor mass and non-responders.

    A 62-year-old woman had multiple plasmacytomas of the skin with no roentgenographic or bone marrow evidence of multiple myeloma. Serum IgA-lambda level was increased to 1,000 mg/dL (normal range, 90 to 450 mg/dL). The skin lesions regressed completely when the patient was treated with melphalan. She had recurrence of a skin plasmacytoma and lytic bone lesions ten months later and died of bronchopneumonia 11 months after the was first seen. Solitary skin plasmacytomas are rare, and multiple skin plasmacytomas are even rarer. Occasionally, these lesions may precede roentgenographic and bone marrow evidence of multiple myeloma.

Vitamin A and retinol-binding protein in patients with myelomatosis and cancer of epithelial origin.
    European journal of cancer & clinical oncology, 1982, Volume: 18, Issue:4

    Serum vitamin A and retinol-binding protein (RBP) concentrations were measured in patients comprising 53 myeloma and 28 epithelial cell cancer cases. Vitamin A levels in these patients were found to be significantly lower than those in the 30 healthy subjects, the effect being more marked in the patients with cancer of epithelial origin. The serum concentrations of retinol-binding protein (RBP) fell in parallel with vitamin A in the epithelial cancer patients, while the RBP concentrations remained unaffected in the patients with myeloma, suggesting that the underlying factor for resulting low vitamin A levels may be different in these two groups of patients.

Pharmacokinetics of oral and intravenous melphalan during routine treatment of multiple myeloma.
    European journal of cancer & clinical oncology, 1982, Volume: 18, Issue:4

    Plasma melphalan levels have been measured in nine (mostly stage IIIA) multiple myeloma patients after therapeutic doses of drug had been given p.o. and i.v. A new isocratic high-pressure liquid chromatographic (HPLC) method with a sensitivity limit o 5 ng/ml was used to quantify the melphalan. Patients receiving 8-28.5 mg melphalan i.v. showed alpha and beta plasma decays with half-lives of 7.7 +/- 3.3 (mean +/- S.D.) and 83 +/- 14 min respectively. The apparent volume of the central compartment was 12.8 +/- 4.3 1, and the total volume of distribution was 0.62 +/- 0.21 l/kg. Very variable absorption was seen in the same patients after receiving 5-12 mg melphalan p.o. The half-life of the absorption phase varied from 2.1 to 62.1 min (22.8 +/- 18.1 min) with delays (before absorption started) of 0-113 min. The fraction of dose absorbed varied from 0.32 to 1.03 (0.72 +/- 0.23), and the half-life of the beta phase was 92 +/- 27 min. The type of breakfast eaten before p.o. melphalan was found to correlate with the fraction of drug absorbed.

Combination chemotherapy for multiple myeloma with melphalan, prednisone, cyclophosphamide, vincristine, and carmustine (BCNU) (M-2 protocol).
    Cancer treatment reports, 1982, Volume: 66, Issue:11

    From January 1975 to May 1981, 25 consecutive patients with multiple myeloma (MM) were entered in a prospective study and treated with the M-2 protocol (melphalan, prednisone, cyclophosphamide, vincristine, and carmustine [BCNU]). The Karnofsky performance status was less than 70 in 62% of the patients. Nineteen patients were classified as being in stage III, three were in stage II, and three were in stage I. All patients had symptomatic and previously untreated MM. In 17 of 21 (80.9%) evaluable patients, an objective response according to Myeloma Task Force criteria was obtained. There was no difference in response rate among patients in the various stages of the disease or according to types of proteins secreted. The median time to obtain an objective response was 2 months and the median duration of the remission is 18+ months. The actuarial median survival was 42 months. In the first 15 months of follow-up, 20% of the patients died. Toxicity was not negligible and was mainly hematologic. One treatment-related death occurred. Our study confirms the efficacy of the M-2 protocol in MM and supports the data reported by the Memorial Hospital group.

Long-term survival in myelomatosis. A report to the MRC working party on leukaemia in adults.

    The patients entered into the Medical Research Council's First Myelomatosis Trial (MRCI) have been followed up for a minimum of 12 years, and an attempt has been made to define features recorded at presentation that might predict long-term survival and to estimate the risk of acute myeloid leukaemia (AML) induced by treatment with either of the alkylating agents, melphalan or cyclophosphamide. In this series, the chance of a patient surviving 5 years was strongly related to the haemoglobin, blood urea concentration (BUC) and performance status at presentation. Other features, including paraprotein levels, type of heavy or light chain, bone lesions and recovery of polyclonal immunoglobulin added little useful information. Six patients died of AML, all after more than 4 years in the trial; the incidence of AML among 4-year survivors was 10%. All six patients had been treated with continuous melphalan and the implications of this for future chemotherapy for myelomatosis are discussed.

Prognostic factors in multiple myeloma treated with prednisolone and sequential melphalan and ifosfamide: MIP combination chemotherapy.
    Acta medica Okayama, 1982, Volume: 36, Issue:1

    Response rates and survival times were studied in 47 patients who had multiple myeloma and who were being treated with Prednisolone and sequential Melphalan and Ifosfamide (MIP therapy). The clinical response was determined by objective parameters such as the reduction of M-protein level, tumor volume and healing of bone destruction. Twenty-eight of the patients (59.6%) responded to the MIP therapy. The 50% survival time as followed from the initiation of treatment to death was 19 months. Of the prognostic factors, the age (greater than or equal to 70 years), clinical stage III of Durie and Salmon, hypercalcemia, extensive bone lesions, and the patho-morphological type IV of Brücher were associated with a decreased life-span. Therefore, MIP therapy was more effective in poor risk (high tumor mass group) than in good risk (low or intermediate tumor mass group) patients, but the survival of patients on MIP therapy was shorter in the poor risk group than in the good risk one. In addition, the group which responded rapidly (i.e. within 2-5 weeks) had longer remission and longer survival than the group which improved slowly (i.e. after 6-16 weeks).

    Five patients with multiple myeloma ending in acute leukemia are described. The preleukemic phase was characterized by anemia, leukopenia and/or thrombocytopenia. The incidence of acute leukemia in myeloma was calculated to be 6%. Melphalan therapy for more than two years increased the incidence to 14%. All patients who developed leukemia had received a total melphalan dose of at least 1 100 mg.

Multiple myeloma: a therapeutic enigma.
    American journal of clinical oncology, 1982, Volume: 5, Issue:1

    Multiple myeloma is one of the few malignancies with a distinct tumor marker, the myeloma protein. This marker, as well as other disease manifestations, can be used to follow the progress of the tumor. Myeloma was also one of the first cancers to respond to chemotherapy and well known are the reports in the early 1960s of good results with melphalan and with cyclophosphamide. Since that time many other agents have been introduced and combination chemotherapy with several drugs were tried extensively. The enigma: Despite the tumor marker and despite the many available drugs there has been very little progress made in improving the outcome of multiple myeloma in the last two decades.

Chronic lymphatic leukemia developing in a patient with multiple myeloma: immunologic demonstration of a clonally distinct second malignancy.
    Cancer, 1982, Aug-01, Volume: 50, Issue:3

    A patient with multiple myeloma who subsequently developed chronic lymphocytic leukemia is reported. Initial studies demonstrated clinical and hematological features of multiple myeloma with an IgM lambda paraprotein. Skeletal disease was a significant presenting feature, although relapse occurred in extraosseous sites, particularly the pleura. He developed chronic lymphatic leukemia 31 months later and immunological studies showed the malignant lymphocytes to have kappa (Kappa) light chain surface immunoglobulin, demonstrating separate clonal origin of this patient's two B-cell malignancies.

Peptichemio induction therapy in myelomatosis.
    Cancer chemotherapy and pharmacology, 1982, Volume: 8, Issue:1

    Fifteen patients with multiple myeloma, two of whom had plasma cell leukemia, were treated between May 1974 and December 1978. Peptichemio was administered intravenously at doses of 40-80 mg/48 h, courses including 4-17 administrations in association with moderate doses of prednisone (15-50 mg/day) and androstanes at high dosages (250 mg weekly). In two patients PTC was associated with vincristine (VCR) administered on the first day of the course. Eight patients were previously untreated, four had been resistant to melphalan (MPH) and/or cyclophosphamide (CTX), and three had been treated irregularly with one or both of these alkylating agents. The criteria of response to therapy are reported. Out of a total of 15 PTC courses administered we obtained 13 responses, eight complete and five partial; no response was achieved in the other two patients. In the four patients who were resistant to MPH and/or CTX we obtained three responses, which were maintained with the same alkylating agent to which they had been resistant previously. The time needed to obtain a response in 90% of the patients was 6 weeks. Peptichemio was shown to be effective in patients in an advanced stage of the disease, in patients with light-chain myeloma and in those with plasma cell leukemia. The association of VCR potentiated the antitumor effect, but also increased the myelotoxicity. The PTC treatment was well tolerated. It is suggested that PTC be used in induction treatment of myelomatosis and in patients resistant to traditional alkylating agents.

Plasma melphalan and prednisolone concentrations during oral therapy for multiple myeloma.
    Cancer chemotherapy and pharmacology, 1982, Volume: 9, Issue:1

    Nine patients with myeloma were studied over 13 oral administrations of 10 mg melphalan and 5-10 mg prednisolone. Plasma melphalan concentrations were estimated by high-pressure liquid chromatography, prednisolone concentrations by quantitative thin-layer chromatography. The mean plasma half-life of unchanged melphalan was 0.9 +/- 0.5 (SD) h. The 'lag-time' before melphalan was detected in the plasma varied from 1 to 4 h, the mean peak concentration was 96 +/- 21 ng/ml, and the mean area under the plasma concentration by time curve was 160 +/- 78 ng h/ml. This variability was consistent with observations made elsewhere following much higher oral doses of melphalan and illustrates the relatively wide interindividual variability of absorption. Observations made in the same subjects on two separate occasions showed lower variability. The melphalan elimination rate was not significantly affected by moderate impairment of creatinine clearance (to 31 ml/min). Absorption of prednisolone in five of these patients was apparently normal and unaffected by concurrent administration of melphalan.

Measurement of plasma melphalan at therapeutic concentrations using isocratic high-performance liquid chromatography.
    Journal of chromatography, 1982, Nov-12, Volume: 232, Issue:2

    A sensitive isocratic high-performance liquid chromatographic (HPLC) method for the measurement of melphalan in plasma is presented. It requires an extraction step using columns of XAD-2 resin before injecting the clarified methanol eluate directly into the HPLC system. The HPLC system uses an isocratic mobile phase containing an ion-pair reagent, and a sensitive fixed-wavelength (254 nm) monitor with a noise specification of less than 2 . 10(-5) absorbance units peak to peak. The concentration of melphalan was followed in a patient with multiple myeloma on day 1 and day 4 of a four-day course of the drug. Little difference was detected between the two curves with terminal half-lives of 71 and 68 min respectively and areas under the curve of 1.08 and 1.15 min . microgram/ml . (mg dose)-1.

Notwithstanding the presumptions of the pathogenesis of amyloidosis and the capacity of colchicine to inhibit amyloid synthesis in rats treated with casein, the form in question derived little benefit from the association of colchicine (0.5 mg t.i.d.) and Melphalan (cycles of 4 days every 6 weeks - 0.25 mg/Kg/die).

Effect of chemotherapy on the anion gap in multiple myeloma.
    Acta haematologica, 1981, Volume: 66, Issue:1

    In 12 myeloma patients responding to chemotherapy (7 IgG and 5 IgA), we studied the effect on the anion gap of a 50% reduction in the serum paraprotein concentration. In contrast to the pretreatment anion gap which was decreased in IgG myeloma and increased in IgA myeloma, the value calculated when the paraprotein spike was halved showed a tendency towards normalization in the former type of myeloma, whereas it appeared as quite normalized in the latter. Our results lend further support to the conceptions that IgG and IgA paraproteins behave in the serum as cations and anions, respectively, and that serial determinations of the anion gap may be of value for monitoring the response to treatment in patients with multiple myeloma.

Drug resistance in multiple myeloma associated with high in vitro incorporation of 3H-thymidine.
    Blood, 1981, Volume: 58, Issue:3

    In multiple myeloma, tumor cell mass and labeling index correlate with subsequent survival duration, but do not predict for response to treatment. In the present study was have autoradiographically measured the incorporation of 3H-thymidine as determined by the number of grains over the myeloma nuclei in bone marrow aspiration samples. In 33/37 patients with less than 50% tumor regression or progressive disease, the pretreatment grain count was greater than or equal to 20/myeloma nucleus. Conversely, values of less than 20 were found in 27/29 patients who had greater than or equal to 50% cell mass reduction. Survival duration was significantly better than (p less than 0.001) in patients with grain counts less than 20. Sixty percent of the patients with both a low labeling index (less than or equal to 3%) and grain count (less than 20) were alive at 48 mo, whereas 15/17 patients with a high labeling index and grain count had a median survival of less than 6 mo. In a subset of 22 patients, there as a significant correlation between in vitro resistance to melphalan, adriamycin, and vincristine as tested in the myeloma stem cell colony assay system and a grain count of greater than 20. We can only speculate as to the reasons for the increased 3H-thymidine uptake by myeloma cells resistant to treatment, however, it could be associated with accumulation of excess DNA and /or increased unscheduled DNA synthesis following injury from alkylating agents.

The growth fraction of human myeloma cells.
    Blood, 1981, Volume: 57, Issue:2

    Greater reductions of tumor load in patients with multiple myeloma may result from therapeutic strategies that are based on a better knowledge of growth kinetics. We have previously shown that the labeling index of myeloma cells remains unchanged when tumor mass is reduced and that the cells of relapsing patients have differnt biologic properties than the cells present before melphalan-prednisone therapy. This study investigated the growth fraction (GF) of myeloma cells at various disease stages using continuous i.v. infusions of tritiated thymidine. We studied 17 patients on 22 occasions (4 untreated, 2 unresponsive, 6 in remission, and 10 in relapse). All untreated an unresponsive patients and 5 of 6 patients in remission had a GF of less than 4%. GF was defined in these studies as the maximum percentage of labeled plasma cells exposed continuously to tritiated thymidine. Relapsing patients, with the most rapid tumor doubling times, had GF ranging from 14% to 83%. The plasma cell transit time through the proliferative compartment for all of the relapsing patients ranged from 6.6 to 11.9 days and the calculated intrinsic cell loss ranged from 50% to 86%. These findings support our model for the growth kinetics of multiple myeloma that assumes that the entire tumor mass issues from a small proportion of proliferating cells and that the growth kinetics of myeloma cells in relapsing patterns differ from those in untreated and unresponsive patients. Therapeutic trials with cycle-active agents need further investigation in selected relapsing patients who are likely to have a high growth fraction.

Lithium carbonate in chronic cluster headache assessment of therapeutic efficacy and possible mechanisms of action.
    Italian journal of neurological sciences, 1980, Volume: 1, Issue:3

    6 patients with chronic cluster headache were treated with lithium carbonate in order to establish the individual lowest effective dose and to assess the possibility of suspending treatment after prolonged administration. Lithium was give at rising doses until more than 90% improvement was obtained. This was achieved in 1 case with only 300 mg daily, in 3 cases with 600 mg and in 2 with 900 mg daily. Of the 5 patients in whom drug administration was suspended 3 had an immediate return of daily attacks of headache, 1 after a 4-month free interval and 1 has maintained the improvement after 6 months without the drug. The sharp decline of the effectiveness of lithium on administration of an antimitotic (Melphalan) provides the starting-point for a discussion on the possible mechanisms of action of lithium in cluster headache.

Cyclic oscillation of blood neutrophils in a patient with multiple myeloma.
    Blood, 1980, Volume: 55, Issue:1

    A patient with multiple myeloma developed periodic blood neutropenia (periodicity of 15-25 days) after 3 yr of intermittent treatment with cytotoxic agents. Peaks of serum colony-stimulating activity (CSA) level coincided with valleys of blood neutrophils. Fraction of marrow neutrophils in the multiplicative pool was high during blood neutrophil valleys and low during neutrophil peaks. In contrast, the maturation storage pool exhibited the reverse pattern. An increased fraction of marrow neutrophilic cells in the multiplicative pool was in active proliferation during a blood neutrophil valley and a decreased fraction during a blood neutrophil peak. These findings suggest that the marrow granulopoiesis was regulated through CSA. The defect causing the periodicity was probably related to the reduced number of neutrophils in the marrow maturation storage pool, which in turn may be related to a reduced and/or defective granulocytic stem cell pool size consequent to the long-term administration of cytotoxic drugs and/or infiltration of the marrow by myeloma cells.

    The variety of cutaneous lesions in primary systemic or multiple myeloma-associated amyloidosis is impressive and includes purpura, waxy papules, tumors, plaques, alopecia, and, rarely, bullae. We report a patient in whom the diagnoses of amyloidosis and multiple myeloma were established after he presented with bullae and extensive infiltrated, purpuric plaques. Immunoelectrophoresis of the blister fluid revealed an IgA kappa monoclonal protein similar to that found in the patient's serum and urine.

Induction of unscheduled DNA synthesis in human myeloma cells.
    Blood, 1980, Volume: 55, Issue:2

    Unscheduled DNA synthesis (UDS) induced by melphalan, nitrogen mustard and ultra-violet irradiation was studied in bone marrow cells from myeloma patients. In a previous study, normal bone marrow cells in various stages of maturation were found to display a gradual decrease in UDS parallel with the process of maturation. Myeloma cells showed a similar pattern. Poorly differentiated myeloma cells exhibited a similar level of UDS to myeloblasts and erythroblasts. Irrespective of which repair-inducing agent was used, the relationship between the levels of UDS in the various cell types was constant. This indicates that the differences in the level of UDS in the various cell types was not due to differences in the uptake of the repair-inducing agent.

The following results were obtained : 1) Only 42.6% of patients respond to induction therapy ; 2) Fewer than 10% of patients showing a response reach a second levelling with Vincristine ; 3) 50% of those not showing a response reach a levelling between --20 and --50 and have prolonged survival ; 4) Only 20% of non responders are improved by Cy P or A and NU. The median actuarial survival is 42 months. Among the responders two poor prognosis factors must be underlined : hypercalcemia and the speed of response.

The ultrastructure of bone marrow plasma cells obtained from patients with multiple myeloma during the clinical course of the disease.
    Acta pathologica et microbiologica Scandinavica. Section A, Pathology, 1980, Volume: 88, Issue:1

    The ultrastructure of plasma cells from 65 consecutive bone marrow specimens from 13 patients with multiple myeloma is described. Biopsies were taken from 12 of the patients prior to and after initiation of treatment. The study was undertaken with the aim of correlating ultrastructural characteristics of the myeloma cells with biochemical and clinical parameters, including the survival time after treatment of the patients with cytostatics. Intranuclear inclusions were only seen in the cells of four patients, all of whom had rather long survival times. Two of these are still alive and, furthermore, their plasma cells are characterized by a low mean number of mitochondria in each sectioned cell studied, i.e. 7 and 14, respectively. Nuclear bodies were found in about 7 per cent of the plasma cells in biopsies taken before treatment was initiated. During treatment this percentage increased significantly to about 16 (2P = 0.004). A nuclear/cytoplasmic asynchrony was a characteristic feature of the ultrastructure of the myeloma cells. During treatment a significant increase from 34 to 54 per cent (2P = 0.03) was observed in the number of plasma cells with slight asynchrony. No correlation could be established between any ultrastructural features and the values obtained with clinical tests considered of major prognostic significance at the time of diagnosis, e.g. the concentrations of serum creatinine, haemoglobin, serum albumin and serum calcium.

Reversible melphalan-induced lung damage.
    The American journal of medicine, 1980, Volume: 68, Issue:5

    Pulmonary toxicity occurs after the administration of several different chemotherapeutic agents. Pulmonary toxicity due to melphalan alone has not been documented. In the patient we describe respiratory symptoms and pulmonary infiltrates developed twice within two weeks of the second course of a monthly melphalan and prednisone regimen. Open lung biopsy revealed interstitial pneumonitis. The infiltrates cleared on both occasions when melphalan was withheld. Special studies performed seven weeks after the last dose of melphalan had been given revealed that the patient's alveolar macrophages suppressed phytohemagglutinin induced blastogenesis of his peripheral lymphocytes. Melphalan itself did not stimulate the blastogenesis of the peripheral lymphocytes. Melphalan should be added to the list of therapeutic agents that induce pulmonary disease. However, the pathogenesis of the disease remains to be elucidated.

    An unambiguous and sensitive method based on gas chromatography-chemical ionization-mass spectrometry has been developed to quantitate L-phenylalanine mustard and has been applied to measure levels in plasma of five patients receiving 0.15 to 0.25 mg/kg (10 to 17 mg) of the drug p.o. Peak plasma levels of 50 to 190 ng/ml were found to occur between 0.7 and 2.3 hr after ingestion. The time for the plasma level to fall to one-half of the peak value varied from 0.6 to 3 hr, and very low levels (less than 2 ng/ml) were present by 24 hr.

Interferon therapy in multiple myeloma.
    Acta medica Scandinavica, 1979, Volume: 205, Issue:3

    A woman with multiple myeloma relapsed after 6 years of satisfactory tumor control with melphalan therapy. When progression then occurred, she was given exogenous human leukocyte interferon, 3 x 10(6) reference units twice daily i.m., as the sole therapy. Side-effects of the interferon therapy consisted of fever reactions and thrombocytopenia. One month after the initiation of interferon therapy there was 1) improvement of general health with less pain and tiredness, 2) reduction of the M-component, IgG-lambda, in the serum, and 3) a reduced plasma cell concentration in the bone marrow. After 5 months of interferon therapy tumor progression occurred despite continuous interferon treatment. At the same time, the tumor cells were less sensitive to interferon in in vitro tests than prior to interferon therapy. It is suggested that interferon therapy should be given as initial treatment to a few patients with multiple myeloma in a phase I trial.

Response to therapy in IgG myeloma patients excreting lambda or kappa light chains: CALGB experience.
    Blood, 1979, Volume: 54, Issue:1

    Sixty-eight previously untreated patients with IgG myeloma who were entered into five protocols of Cancer and Leukemia Group B (CALGB) were studied in order to determine the possible influence of excretion of kappa versus lambda urinary light chains on responses to treatment and survival. All patients in these protocols were included if the serum and urine protein abnormalities were confirmed by one of the two group reference laboratories. Pretreatment characteristics of the two groups of patients did not differ significantly. Of 44 patients with kappa Bence Jones proteinuria, 19 patients (43%) had good responses to treatment, whereas only 3 of 24 patients (13%) with lambda Bence Jones proteinuria had good responses (p = 0.02). Survival for the patients excreting kappa light chains was significantly better than survival for patients excreting lambda chains (median survival 31 versus 12 mo, p = 0.02).

    A case of nonproductor myeloma is reported. The diagnosis was supported by the radiological findings, the heavy marrow infiltration of malignant plasma cells, the absence of a monoclonal component in the serum or urine and the failure to demonstrate intracytoplasmic immunoglobulins with immunoifluorescent techniques. The clinical findings of our patient are similar to those reported for the 5 cases of nonproductor myeloma described so far, indicating that there are no characteristic features differentiating nonproductor myeloma from productor myelomas.

    56 cases of myeloma observed since 1956 are reviewed and it is noted that course, prognosis and survival have changed in relation to the improvement in diagnostic procedures and therapeutic aids. The recent introduction of polychemotherapeutic approaches based on theoretical considerations has not yet been fully vetted in the clinic although a higher percentage of remissions compared to that obtained by monochemotherapy would seem to be confirmed. Personal experience with a new polychemotherapeutic schema in advanced myeloma resistant to monochemotherapy + prednisone is reported.

Solid tumors in multiple myeloma.
    Annals of internal medicine, 1979, Volume: 90, Issue:5

    The frequency of solid tumors was evaluated in 628 consecutive patients with multiple myeloma who had been treated with various melphalan-prednisone combinations. Among those patients who lived at least 2 months, the incidence and diversity of second tumors were similar to those in normal persons of the same age and duration at risk. The diagnosis was usually made within 2 years after the start of chemotherapy for the myeloma. Long-term melphalan therapy did not seem to contribute to the pathogenesis of second solid tumors in patients with multiple myeloma.

    A 46-year-old woman presented and IgG myeloma without metastases at the time of the diagnosis. A complete hematologic remission was achieved with melphalan and prednisone, but the patient then developed a polysymptomatic condition with myelomatous metastases in different organs. In some cases these were confirmed histologically (meninges, stomach, skin, and scalp); in others there was a strong clinical evidence (liver, oral mucosa, lymph nodes, and lumbar vertebra). There were manifestations of the disease in all of these sites, while complete hematologic remission was maintained. The meningeal metastasis was treated by surgery and irradiation with orbital penetration; the lymph nodes were irradiated, and COPP polychemotherapy was given to treat the rest of the metastatic localizations. In this way an apparently remission was achieved temporarily. The incidence of each one of the extraskeletal manifestations in this unusual case of myeloma is reviewed in the literature.

[2 cases of multiple myeloma with osteosclerosis].
    Schweizerische medizinische Wochenschrift, 1979, Nov-17, Volume: 109, Issue:44

    A report on two patients with osteoclerotic myeloma is presented (myeloma with osteoblastic lesions). In case one, metastatic bone tumor of unknown origin was wrongly diagnosed initially. Because of increasing neurological symptoms laminectomy was performed. Biopsy led to the correct diagnosis of multiple myeloma of IgA-type. Patient also had a very severe peripheral neuropathy. The second patient had pancytopenia and osteosclerotic lesions of the pelvis. Bone marrow aspiration revealed so-called "empty marrow". Based on these findings, myelofibrosis was wrongly diagnosed at another hospital. Bone marrow aspiration, paper- and immunoelectrophoresis subsequently produced the correct diagnosis of multiple myeloma of IgG-type. Multiple myeloma usually is characterized by osteolytic lesions of the bones. However, the literature contains some 50 cases with osteosclerotic multiple myeloma, three different forms of which are described. In a fairly large percentage osteosclerotic multiple myeloma is combined with periphereal polyneuropathy. It would appear that in IgE-myeloma the incidence of sclerotic lesions is higher. Osteosclerotic multiple myeloma is very rare. It should however be considered if the differential diagnosis of osteosclerotic bone lesions is established.

[Analysis of the results of treatment of multiple myeloma].
    Acta haematologica Polonica, 1979, Volume: 10, Issue:4

    Therapeutic results were analysed in 62 cases of multiple myeloma treated by two-stage method: I. with cyclically non-specific agents (melphalan) in each case. When this treatment was a failure the second step was given: II. cyclically specific and non-specific agents by the M-2 schedule. Good therapeutic response was obtained in 70% of cases. The mean survival time in the whole group was 35 months, and in the subgroup with good prognosis it was 44 months. Most (74%) patients with IgG M-protein responded well to treatment with cyclically non-specific agents, while only 50% of those with IgA M-protein had a good response to them.

Quantitation of differential sensitivity of human-tumor stem cells to anticancer drugs.
    The New England journal of medicine, 1978, Jun-15, Volume: 298, Issue:24

    With a direct in vitro tumor-colony assay developed to measure sensitity of human-tumor stem cells to anticancer drugs, we performed 32 retrospective or prospective clinical studies in nine patients with myeloma and nine with ovarian cancer treated with standard agents that were tested in vitro. The results were clearly correlated (P is less than 0.00001). Unique patterns of sensitivity and resistance to the six drugs tested were observed for individual patients. In eight cases of myeloma and three of obarian carcinoma in vitro sensitivity corresponded with in vivo sensitivity whereas in one case of myeloma it did not. In vitro resistance correlated with clinical resistance in all five comparisons in myeloma and all 15 in ovarian cancer. We conclude that this assay shows sufficient promise to warrant larger-scale testing to determine its efficacy for selection of new agents and individualized cancer chemotherapy regimens.

IgG2a-producing variants of an IgG2b-producing mouse myeloma cell line.
    The Journal of experimental medicine, 1978, Jun-01, Volume: 147, Issue:6

    12 variant cell lines producing an IgG2a (kappa) immunoglobulin derived via different routes from the IgG2b (kappa) synthesizing MPC 11 were studied. These variants all have the parental MPC 11 idiotype as shown by a radioimmunoassay. A comparison of the variants by charge, peptide maps, and assembly patterns has shown that most of them differ from one another, and some can be grouped. One group consists of three primary variants generated with two mutagenic agents: these three have almost indistinguishable peptide maps. Two other primary variants which arose in a similar fashion differ markedly from each other and from this group. A second group is comprised of the four secondary variants which arose from two short heavy chain producing primary variants. Other secondary variants and the one spontaneously arising variant cannot be grouped. Possible genetic mechanisms such as translocation, expression of previously silent genes and recombination are discussed.

Sideroblastic anaemia and leukaemia in multiple myeloma.
    Australian and New Zealand journal of medicine, 1978, Volume: 8, Issue:5

    Two patients with IgA myeloma and one patient with kappa light chain disease developed sideroblastic anaemia from two to four years after the initial diagnosis. All had previously received radiotherapy and chemotherapy (melphalan and prednisone). In two patients the myeloma was quiescent when the sideroblastic change occurred. Leukaemia occurred in two patients two and seven months respectively after the diagnosis of sideroblastic anaemia was made. In one of them, the myeloma became active again at the same time. The development of sideroblastic anaemia may be a pre-leukaemic event and may be recognised by the appearance of a dimorphic blood film.

Cytomegalovirus pneumonia after treatment with melphalan and prednisone. Report of a case.
    Acta medica Scandinavica, 1978, Volume: 203, Issue:4

    A patient with multiple myeloma had pancytopenia after treatment with melphalan and prednisone and died of an interstitial pneumonia. Post-mortem examinations showed cytomegalic cells in the lungs. Lung tissue showed a high titer of cytomegalovirus. Only when other causes have been ruled out by microbiologic, serologic, and histologic examinations should melphalan be believed to cause respiratory illness.

Bence Jones proteins and light chains of immunoglobulins. XV. Effect of corticosteroids on synthesis and excretion of Bence Jones protein.
    The Journal of clinical investigation, 1978, Volume: 61, Issue:1

    The effect of corticosteroids and cytotoxic chemotherapeutic agents on the excretion of Bence Jones protein was determined for periods of 1 - 62 mo in 29 patients with multiple myeloma and Bence Jones proteinuria. The amount of protein present in 24-h urine specimens collected before treatment and at frequent intervals during monthly treatment cycles was determined. Striking variations occurred in the amount of Bence Jones protein excretion; these changes were especially evident when 75 mg of prednisone were given daily for 7 days as part of a monthly chemotherapeutic regimen. Within the 7-day period seven patients showed essentially no decrease (<25%), whereas 13 and 9 patients had a moderate decrease (25-75%) or a marked decrease (>75%), respectively, in Bence Jones proteinuria as compared to pre-treatment values. The decrease in excretion of Bence Jones protein during this period was attributed mainly to corticosteroid therapy because of the transient nature of the response in most patients and the lack of such response in three patients when the hormone was omitted. Biosynthetic studies were performed to determine in vitro the effect of corticosteroids on Bence Jones protein synthesis. Plasma cells obtained from the bone marrow of 13 patients were incubated in a growth medium containing (14)C-labeled lysine and isoleucine and prednisone in concentrations up to 240 mug/ml, and the amount of Bence Jones protein synthesized was determined immunochemically. No differences in viability were apparent between untreated and prednisone-treated cells. The type of response exhibited by an individual patient in the percent decrease of Bence Jones protein excreted after 7 days of prednisone treatment was comparable to the percent decrease in newly-synthesized Bence Jones protein secreted by tumor cells when cultured in the presence of prednisone at a concentration of 120 mug/ml. The marked differences in the capacity of corticosteroids to affect Bence Jones protein synthesis appear to reflect a biochemical heterogeneity among plasma cell neoplasms.

Multiple myeloma complicating the course of seronegative systemic lupus erythematosus.
    Arthritis and rheumatism, 1978, Volume: 21, Issue:2

    A patient with a 20-year history of clinical systemic lupus erythematosus (SLE) who later developed multiple myeloma is described. SLE was diagnosed on the basis of a butterfly rash, photosensitivity, nondeforming arthritis, pleuropericarditis, and alopecia. However, the patient has never had LE cells, antinuclear antibody, or depressed complement. The patient was treated with intermittent courses of corticosteroids over a 20-year period with good results. Multiple myeloma, diagnosed by bone marrow biopsy, has responded favorably to therapy with L-phenylalanine mustard and prednisone.

Factors responsible for bone marrow toxicity after treatment of myeloma patients with different alkylating agents.
    Acta medica Scandinavica, 1978, Volume: 203, Issue:4

    Leukopenia and thrombocytopenia were studied after loading doses of melphalan (5 mg/daily for 18-25 days) in 71 myeloma patients. Seventy per cent of the patients developed pronounced leukopenia (white cells less than 2.0 X 10(9)/l) and/or thrombocytopenia (platelets less than 100 X 10(9)/l). The patients with pronounced and moderate hematological side-effects, respectively, were compared for weight and age. The body weight was the same in the two groups, indicating that the patient's weight is of minor importance for the dosage of melphalan. There was a numerical difference in age, on the borderline for statistical significance, indicating that the age of the myeloma patient may be of minor importance for the dosage of melphalan. It is possible that more pronounced age differences may be of greater importance in this respect. Fifteen patients with myeloma were treated with cyclophosphamide. Compared with melphalan, the effect on white cells was the smae, while the incidence of thrombocytopenia was statistically significantly lower with cyclophosphamide.

Pyoderma gangraenosum (dermatitis ulcerosa) and monoclonal (IgA) globulin healed after melphalan treatment. Case report and review of the literature.
    Acta medica Scandinavica, 1978, Volume: 203, Issue:4

    Since 1968 we have been treating a patient, who has had a combination of pyoderma gangraenosum (dermatitis ulcerosa) and signs that may indicate early multiple myeloma. She also had carcinoma of the colon, which was successfully operated. The pyoderma healed later after intensive and successful cytostatic treatment of the "myeloma". The ulcers remain practically healed and the protein pattern is normal in May 1977. Such cases are rare and a search in the literature has not been very rewarding. In our own series of more than 200 cases with myeloma this combination is unique. The lieterature is discussed in detail with data on the follow-up on some of the patients.

Unmaintained remissions in multiple myeloma.
    Blood, 1978, Volume: 51, Issue:6

    Twenty-eight patients with multiple myeloma responding to prior melphalan-prednisone combinations, but without additional chemotherapy, were followed until relapse. Patients receiving no further treatment had a median survival time similar to that of those receiving indefinite courses of melphalan-prednisone or carmustine-prednisone. Prolonged periods of unmaintained remission occurred primarily in patients without extensive disease at the time of diagnosis or in whom the abnormal protein disappeared from the electrophoresis strip. The initial relapse after an unmaintained remission was controlled in 80% of patients with the resumption of melphalan-prednisone, but second remissions were usually less marked in degree and shorter in duration. Results supported the long-term evaluation without chemotherapy of selected patients with low numbers of plasma cells after treatment who were likely to experience long durations of disease stability and respond again to retreatment with melphalan-prednisone.

[Successful haemodialysis treatment of acute renal failure in a patient with multiple myeloma (author's transl)].
    Medizinische Klinik, 1978, May-05, Volume: 73, Issue:18

    A case of multiple myeloma with severe osteolytic destructions and myeloma kidney is presented, in whom a rapidly progressive renal insufficiency because of hyponatraemia and dehydration developed. After 5 months of regular dialysis treatment diuresis increased and a sufficient global kidney function recurred. Aetiological factors and the pathomechanisms of acute renal failure in multiple myeloma are discussed. We assume that acute renal insufficiency is - in rare cases - at least partly reversible. Therefore patients with acute renal failure and multiple myeloma should not be excluded from haemodialysis treatment because even complete rehabilitation can be achieved.

    Criteria for the diagnosis of multiple myeloma and differential diagnostic considerations are presented. The indications for treatment are discussed. Combination of melphalan or cyclophosphamide with prednisone may be considered standard therapy today. This produces objective tumor regression in 50-70% of patients. The parameters for determining remission and their significance with regard to survival and tumor cell mass are discussed. The importance of supportive measures is stressed. Persistent problems and potential for improving present therapy are discussed.

A new basis for treatment of multiple myeloma.
    Schweizerische medizinische Wochenschrift, 1978, Oct-14, Volume: 108, Issue:41

    In order to get a better understanding of tumor biology, prognostic factors and approaches to treatment, total body tumor cell number, cell kinetics and drug sensitivity have been studied in a series of patients with multiple myeloma. We found that the presenting tumor mass stage was inversely proportional to survival, but did not predict drug sensitivity. Patients with both a high tumor cell mass and a large proliferative compartment of tumor cells had a particularly poor prognosis. Studies of myeloma stem cells in agar culture showed individual patterns of drug sensitivity with a correlation between in vitro sensitivity to melphalan, adriamycin, and BCNU, with in vivo sensitivity to these same classes of agents. Use of such measurements may permit selection of useful new drugs as well as an individualized basis for treatment of multiple myeloma.

Adriamycin, 1,3-bis (2-chloroethyl) 1 nitrosourea (BCNU, NSC No. 409962), cyclophosphamide plus prednisone (ABC-P) in melphalanresistant multiple myeloma.
    Cancer, 1978, Volume: 42, Issue:3

    Fourteen patients with multiple myeloma resistant to melphalan plus prednisone were treated with BCNU 50 mg/m2 plus cyclophosphamide 200 mg/m2 on day 1, adriamycin 20 mg/m2 on day 2 and prednisone 60 mg orally, daily for days 1 through 5. Therapy was repeated every four weeks. Depending upon criteria used, objective antitumor responses were achieved in five to nine of the 14 patients. Mean survival was 9.5 months and actuarial median survival was 7.0 months. Six patients are alive, four to 35 months after initiation of therapy. This preliminary report indicates that this combination may be a useful treatment program in the management of patients with advanced multiple myeloma. A review of studies employing adriamycin plus BCNU suggests that these regimens currently offer the most effective treatment of melphalan-resistant patients.

Prognostic factors and treatment of multiple myeloma: interest of a cyclic sequential chemohormonotherapy combining cyclophosphamide, melphalan, and prednisone.
    Recent results in cancer research. Fortschritte der Krebsforschung. Progres dans les recherches sur le cancer, 1978, Volume: 65

    1. A type 2 therapeutic trial consisting of the administration of monthly cycles of chemohormonotherapy, each cycle combining weekly sequences of mephalan, prednisone, cyclophosphamide, and prednisone, has been achieved in 20 stage II or III myeloma patients. Tolerance of this regimen in treated out-patients was found to be excellent. Preliminary data indicate that the better survival rate in patients treated by this regimen is still not reached at a 30-month follow-up examination by three other nonrandomized control groups of patients receiving continuous therapy with prednisone alone, prednisone + cyclophosphamide, or prednisone + melphalan. 2. Analysis of the main prognostic factors of the four trials indicates that a) IgG-type myelomas are associated with a better prognosis than IgA type; nonexcreting myelomas are associated with the best prognosis, while Bence Jones myelomas are associated with a prognosis as poor as that of the IgA type; b) tumor volume as well as renal insufficiency, at the time of diagnosis, are also prognosis factors; this study confirms the prognostic value of the recently proposed clinical staging system based on these parameters but outlines that 10% of the patients died from a cause not directly related to myeloma plasmocyte proliferation. 3. In conclusion, these results point out: a) the possible advantage of using two alkylating agents instead of one at the beginning of the disease; b) the need to classify multiple myeloma according to prognosis before attempting therapeutic trials.

    In 19 patients with multiple myeloma tumor cell mass was determined. In addition the influence of tumor cell number on certain clinical parameters as well as on survival time has been analysed. In some patients the behaviour of tumor cell number in the course of different therapeutic regimen was studied. A close correlation between tumor cell mass on the one side and certain clinical parameters as well es more objective rationale for planning further therapy regimen can be obtained with the application of this method.

Multiple myeloma associated with Kaposi sarcoma.
    Acta haematologica, 1977, Volume: 58, Issue:2

    A patient with multiple myeloma (MM) who developed Kaposi sarcoma (KS) is described. The KS appeared 18 months after the diagnosis of MM and 1 month after the treatment was changed from cyclophosphamide to melphalan. The treatment with melphalan was discontinued and the spread of the KS was arrested by irradiation and bleomycin. One month after the melphalan was restarted, the KS advanced. The patient died 28 months after the diagnosis of MM and 10 months after KS had developed. The association of KS and MM is discussed and the previously reported cases are reviewed. A possible connection between the treatment with melphalan and the development of KS is proposed.

Plasma cell leukemia: response to conventional myeloma therapy.
    Journal of medicine, 1977, Volume: 8, Issue:6

    A 76-year-old man with plasma cell leukemia was treated with L-phenylalanine mustard and prednisone (CLGB 7461). There was good partial remission of the plasma cell disease characterized by disappearance of the plasma cells in the peripheral blood, reduction of plasma cells in the marrow aspirates to less than 5% of the nucleated hematopoietic cells, a reduction in the serum monoclonal IgG from 7.6 to 2 gms/100 ml, and the disappearance of urinary monoclonal IgG, Bence-Jones protein and a complex of gamma-chain fragment and beta2-microglobulins. There was also a marked improvement in the renal function and a decrease in the proteinuria from 4+ to 1+. The patient relapsed after more than 8 months of response and failed to respond to subsequent treatment with cytoxan and cytosine arabinoside. However, the efficacy of standard myeloma therapy was clearly apparent in this case of plasma cell leukemia.

Acute leukemia in multiple myeloma.
    Annals of internal medicine, 1977, Volume: 86, Issue:4

    Of 476 patients with multiple myeloma treated during a 9-year period, 11 developed acute myelogenous leukemia or sideroblastic anemia. In all, the myeloma was in remission from chemotherapy with melphalan-prednisone combinations that had been continued for a median duration of 3 years. The incidence of acute leukemia or sideroblastic anemia was about 100 times higher than found in normal individuals of the same age. In all patients studied, major cytogenetic abnormalities were present, with hypodiploidy and evidence of chromosomal damage being noted most frequently. The frequency and nature of the chromosome changes were attributed to effects resulting from the prolonged drug therapy. These findings supported the long-term follow-up of selected patients with myeloma without any chemotherapy when marked degrees of remission followed the initial treatment courses.

    A report is presented on two patients with the very rare combination of thrombocythaemia and multiple myeloma. Both patients displayed an increase in monoclonal immunoglobulin in the serum, an increased amount of plasma cells in the bone marrow, and multiple osteolytic lesions in the skeleton, along with a platelet count exceeding 1 mill./mm3, haemorrhagic diathesis, and thromboembolic complications. In case 1, both diseases reacted favourably to treatment with melphalan during a 36-month follow-up. In case 2, the thrombocythaemia had been brought under control with busulphan prior to the diagnosis of myeloma. The latter patient died before initiation of treatment of the myeloma. The signifacance of the combination is discussed.

Multiple myeloma: uncommon or uncommonly diagnosed?
    Postgraduate medicine, 1977, Volume: 61, Issue:5

    The experience of a solo practitioner suggests that the incidence of multiple myeloma is higher than the widely reported figure of 2.7/100,000. Only by early recognition and treatment will the survival rate be increased. Measurement of the sedimentation rate may be helpful in spotting the disease, for a rapid rate in patients with bone pain and anemia suggests multiple myeloma.

Kaposi's sarcoma after long-term alkylating agent therapy for multiple myeloma.
    Southern medical journal, 1977, Volume: 70, Issue:8

    Described is a patient with multiple myeloma who, during long-term treatment with alkylating agents, developed cutaneous Kaposi's sarcoma. Patients with multiple myeloma, unlike those with malignant lymphoma, do not usually develop Kaposi's sarcoma during the natural course of the disease. It is suggested that the immunosuppression resulting from the long-term alkylating agent therapy for multiple myeloma may have prediposed this individual to the development of Kaposi's sarcoma.

Intermittent melphalan and prednisolone therapy in plasma cell myeloma.
    Acta medica Scandinavica, 1977, Volume: 202, Issue:1-2

    Thirty-two consecutive, previously untreated patients with plasma cell myeloma were treated with 4-day courses of melphalan (0.25 mg/kg/day) and prednisolone (2 mg/kg/day) every sixth week. The observation period ranged from 26 to 75 months and the total median survival time was 29 months. 75% of the patients responded to therapy and their median survival time was 42 months. Sex did not influence either the response rate or the survival time. Most patients were treated in an out-patient clinic and required a minimum of check-ups.

Tumor growth patterns in multiple myeloma.
    Cancer, 1977, Volume: 39, Issue:3

    Serial changes in tumor mass were evaluated in 61 patients with multiple myeloma who had received intermittent courses of melphalan-prednisone until death. The variations in the kinetics of tumor reduction and relapse could be explained by a mathematical model based on two cell populations, one sensitive to and one resistant to chemotherapy. For all responding patients, the median tumor halving-time was 1.3 months and the median doubling time was 2.9 months. The duration of a constant tumor mass during remission was brief in most patients. A larger fraction of resistant cells prior to therapy was associated with a slower tumor doubling-time during relapse. With a constant fractional reduction of sensitive cells and a tumor halving-time of one month or less, all cells sensitive to alkylating agents would be eliminated with 3 years of uninterrupted intermittent therapy.

Prediction of the complete growth pattern of human multiple myeloma from restricted initial measurements.
    Cell and tissue kinetics, 1977, Volume: 10, Issue:6

    A method is presented for predicting the complete growth pattern of human IgG multiple myeloma from a few initial measurements of tumour cell number. This permits identification of patterns of undisturbed neoplastic growth in individual patients whose therapy cannot ethically be withheld for long periods. Since the unperturbed growth pattern is a necessary part of the information required for the prediction of individual patient response to alternative treatment schedules, the prospects for improved treatment of human multiple myeloma by optimal scheduling of drug administration are greatly increased.

Clinical evaluation of Asaley.
    Medical and pediatric oncology, 1977, Volume: 3, Issue:4

    Asaley is an L-leucine derivative of sarcolysin which is more active against some rodent tumors. Studies in the USSR demonstrated activity in patients with ovarian and breast carcinoma, Hodgkin's disease, and multiple myeloma. This study in 73 evaluable patients indicated that an appropriate oral dose for patients with adequate bone marrow is 800 mg/M2/day X 4 days at 5-6 week intervals. The most common toxicities were myelosuppression, nausea, and vomiting. Antitumor activity was observed in 2 of 24 evaluable patients with melanoma, and stabilization of previously progressive disease was observed in patients with adenocarcinoma of the colon, multiple myeloma, lymphoma, breast carcinoma, and thyroid carcinoma. Responses were minimal and of short duration but most of the patients had received extensive prior therapy.

    Serum beta-lipoprotein and other specific protein concentrations were measured in 56 patients suffering from multiple myelomatosis, "benign" paraproteinaemia or Waldenström's macroglobulinaemia and in 56 control subjects. The mean level of B-lipoprotein in untreated patients with multiple myelomatosis and macroglobulinaemia was significantly lower than that of the controls. Patients who responded to chemotherapy showed a rapid return to normal of the beta-lipoprotein concentration, while the level remained unchanged in most of those who did not.

Monoclonal B-lymphocytes in peripheral blood of patients with plasma cell myeloma. Relation to activity of the disease.
    Scandinavian journal of haematology, 1976, Volume: 16, Issue:2

    Antisera were produced in rabbits against idiotypic determinants of the myeloma protein from 3 patients with IgG-k myeloma. The antisera did neither cross-react nor react with normal immunoglobulin (Ig). Idiotypic Ig-structures were demonstrated by indirect immunofluorescence (IFL) on 70-94% of peripheral B-lymphocytes inuntreated patients. The total numbers of circulating B-lymphocytes were increased with a simultaneous decrease of T-lymphocytes. Only one of the patients had blood lymphocytes which stained for cytoplasmic Ig with idiotypic antiserum. The monoclonal lymphocyte population decreased gradually during treatment. Plasma cell counts in bone marrow, IgG concentration in serum and erythrocyte sedimentation rate decreased simultaneously, whilt the haemoglobin concentration increased. Very few monoclonal lymphocytes were present during remission. Later, the monoclonal lymphocyte population began to increase in 2 of the patients in parallel with clinical signs indicating relapse. It is concluded that presence of monoclonal B-lymphocytes indicates dissemination of the disease and that they may belong to the malignant cell clone.

Management and prognosis of multiple myeloma.
    Mayo Clinic proceedings, 1976, Volume: 51, Issue:12

    Patients with asymptomatic or smoldering multiple myeloma should not be treated but should be observed closely for progression. For symptomatic myeloma, chemotherapy is indicated. Melphalan, the agent of choice, should be given with prednisone for 1 week of every 6 weeks, If melphalan brings no response, or response and then relapse, cyclophosphamide (Cytoxan) should be give intravenously every 4 weeks or orally every day. BCNU, CCNU, and doxorubicin (Adriamycin) have also shown activity in myeloma. Hypercalcemia occurs in one-third of patients and should be countered with hydration, corticosteroids, Neutra-Phos, or mithramycin. Long-term hemodialysis has achieved some success. The combination of sodium flouride and calcium carbonate produces new bone formation; it seems a useful adjunct in treatment for myelomatous bone disease. Radiation should be utilized only for severe, localized pain or for solitary lesions. Survival with multiple myeloma varies, mean durations being 2 to 3 years. Multivariate analysis indicates that serum creatinine and calcium levels are the most significant indicators regarding 2-year survival. We have found monoclonal proteinuria not significantly more frequent with renal insufficiency than with normal renal function, renal insufficiency not significantly more frequent with lambda than with kappa chains, and survival not significantly greater with IgG myeloma than with IgA.

Light chain myeloma with features of the adult Fanconi syndrome: six years remission following one course of melphalan.
    Acta medica Scandinavica, 1976, Volume: 199, Issue:6

    A 41-year-old woman, presenting with renal failure, renal glucosuria and moderate anemia, was found to have light chain myeloma, indicated by a kappa chain M-component in the serum, heavy urinary excretion of kappa chains and plasma cell infiltration of the bone marrow. After administration of one course of melphalan, resulting in transient pancytopenia, the light chains disappeared completely, renal function returned to normal, glucosuria disappeared and the Hb concentration normalized. During an observation period of six years she has remained in good health and there has been no sign of relapse.

Duplication of part of the long arm of chromosome 1 in marrow cells of a treated case of myelomatosis.
    Blood, 1976, Volume: 48, Issue:4

    In a case of classical myelomatosis treated with melphalan, a clone of cells with a chromosomal abnormality was found in the bone marrow during remission. There was good reason to think that the hemopoietic cells, rather than plasmacytoma cells, were implicated. Although the clone persisted, no evidence of leukemia developed over a period of observation of 2 yr. The anomaly was interpreted as a duplication of part of the long arm of chromosome 1, which appeared to involve the segment q21 to q31.

Mephalan in the treatment of multiple myeloma.
    Clinical bulletin, 1976, Volume: 6, Issue:4

    Seventy-three patients with symptomatic multiple myeloma at Memorial Sloan-Kettering Cancer Center were treated with melphalan from 1963-1967. All patients but one were followed for three years or until their death. Of the 60 evaluable patients, 31 obtained no benefit, 20 patients had objective and subjective responses consistent with clear clinical benefit; 6 patients had subjective responses in the absence of objective change, and 3 patients had stabilization of their disease. Toxicity was tolerable. It was not possible to predict which patients would respond, utilizing clinical status, hematological status or protein excretion patterns (i.e., which type of light chain was produced). In previously untreated patients, survival from time of diagnosis is 21 months. The median survival of the melphalan responders (39 months) is longer than that for the patients with no response (15 months). These data will provide useful baseline material for the evaluation of future therapeutic trials in patients with multiple myeloma at this Center.

The morphology of dyserythropoiesis in a patient with acute erythroleukaemia associated with multiple myeloma.
    Scandinavian journal of haematology, 1976, Volume: 17, Issue:5

    A patient with multiple myeloma in whom acute erythroleukaemia developed 5 years following treatment with irradiation and melphalan is reported. Immunoglobulin synthesis and immunofluorescence investigations provided evidence that the blast cells in the peripheral blood did not belong to the plasma cell series; ultrastructure examination demonstrated their myeloid origin. Chromosomally abnormal cells were observed in both the bone marrow and peripheral blood. Light-and electron microscopy of erythropoiesis in this case showed distinct features of dyserythropoiesis, similar to those described in other entities. The erythroid cell abnormalities are discussed in the light of their being either indications of malignancy or of a reactive process.

Acute leukemia as a delayed consequence of cancer chemotherapy.
    Cancer, 1976, Volume: 37, Issue:2 Suppl

    Acute myelocytic leukemia occurring many years after intensive radiotherapy and/or chemotherapy has been reported in 82 patients with Hodgkin's disease, 58 patients with multiple myeloma, and 40 patients with chronic lymphocytic leukemia. The precise incidence of this occurrence is uncertain, since the total number of patients at risk is unknown. Most patients with Hodgkin's disease had received intensive radiation therapy. Many also received chemotherapy. One-third of the patients with myeloma were treated only with melphalan. Acute leukemia may occur as part of the natural history of Hodgkin's disease and multiple myeloma; it has been seen with increasing frequency in recent years due to improved survival secondary to better treatment. It is also possible that radiotherapy and/or chemotherapy may be causally related to the development of acute leukemia.

Ancillary measures in treatment of myeloma. Use of immune serum globulin, fluoride, or androgen.
    Archives of internal medicine, 1975, Volume: 135, Issue:1

    We reviewed the efficacy of three agents advocated as ancillary therapy in myeloma patients. Intramuscularly administered immune serum globulin (gamma globulin) was ineffective in preventing infection. Hemoglobin level was improved in some myeloma patients receiving androgens. However, the response rate and the degree of leukopenia or thrombocytopenia were not superior with androgen-melphalan-prenisone combination therapy, as compared with those resulting from the two-drug combination without androgen. A controlled study evaluating androgen plus melphalan has not been done. The long-term administration of fluoride, supplemented by calcium and androgen, induced radiologically apparent bone fluorosis, but strengthening of lytic bone was not observed. Neither objective nor subjective benefit was demonstrated in a controlled study comparing the effects of fluoride (without calcium supplement) with those of the placebo.

Treatment of osteolytic myelomatosis with mithramycin.
    Lancet (London, England), 1975, Mar-29, Volume: 1, Issue:7909

    The treatment of rapidly progressive skeletal demineralisation in myelomatosis has been studied with the help of metabolic calcium balance in two patients; In one, osteoporosis accelerated during treatment with melphalan and prednisolone, although he remained normocalcaemic throughout, suggesting that osteoporosis was aggravated by corticosteroid therapy. In the other patient, who was initially hypercalcaemic, conventional treatment produced clinical remission before eventual relapse with more hypercalcaemia and skeletal dissolution. Both patients were then treated with mithramycin alone, and, although neither obtained haematological remission, bone pain was relieved, hypercalciuria and hypercalcaemia were abolished, and calcium balances proved that mithramycin was effective in restoring calcium equilibrium. The results indicate that mithramycin may abolish excessive bone resorption in myelomatosis and that severe bone dissolution may occur in the absence of hypercalcaemia. Regular determination of 24-hour urinary calcium excretion as well as of plasma-calcium is important in monitoring process. Mithramycin should be considered in the early treatment not only of hypercalcaemia but also of severe hypercalciuria, if these complications do not rapidly remit during the first course of conventional myeloma therapy, with or without steroids. Finally, these results add to evidence that a humoral factor may be responsible for osteoclast stimulation in myelomatosis.

Amyloidosis associated with dermatomyositis and features of multiple myeloma. The progression of amyloidosis associated with corticosteroid and cytotoxic drug therapy.
    The American journal of medicine, 1975, Volume: 59, Issue:3

    Described here is a 59 year old man with dermatomyositis and hypogammaglobulinemia. His muscle power improved after corticosteroid therapy, but extensive amyloidosis and repeated infections appeared. Bone marrow morphology suggested multiple myeloma, but treatment with cytotoxic drugs had no beneficial effect on the amyloidosis. Because of rapid progression of the amyloidosis and further infections, cytotoxic drug therapy was stopped, corticosteroid dosage was decreased, and supplementary immunoglobulin therapy was instituted. The infections occurred less frequently and the amyloidosis appeared to regress. This case suggests that immunosuppressive therapy may exacerbate amyloidosis. The literature is reviewed, and the possible role of humoral immunodeficiency in the pathogenesis of amyloidosis is discussed. It is suggested that supplementary immunoglobulin may be beneficial in amyloidosis.

Expansion of the growth fraction in multiple myeloma with alkylating agents.
    Blood, 1975, Volume: 45, Issue:1

    Patients with IgG multiple myeloma underwent serial studies of tumor cell kinetics including (1) estimation of the total body myeloma cell number (TBMC), (2) measurement of the myeloma cell tritiated thymidine labeling index (LI), and (3) calculation of the total number of myeloma cells undergoing DNA synthesis. Intermittent courses of chemotherapy with cycle-non-specific agents such as melphalan resulted in a marked increase in the LI of myeloma cells in patients who had a 75% reduction in TBMC. The long "plateau" phase of partial remission of myeloma in these patients was associated with a continued high LI: this suggests that the plateau resulted from a balance between the cytoreductive effects of chemotherapy and expansion of the growth fraction (GF) of the tumor. Preliminary attempts to capitalize therapeutically on this expansion of the GF in several patients included administration of the cycle-active agents vincristine and cytosine arabinoside. Vincristine appeared to induce a further reduction in tumor in several patients, although cytosine arabinoside appeared to be ineffective despite clear evidence of its inhibition of DNA synthesis in myeloma cells in vivo. Further clinical studies of the effects of cycle-active drugs on myeloma appear to be warranted; however, successful exploitation of the dynamic change in myeloma cell kinetics with chemotherapy will require the use of cycle-active agents with marked selective toxicity for myeloma cells.

Treatment of plasma cell myeloma with cytotoxic agents.
    Archives of internal medicine, 1975, Volume: 135, Issue:1

    Because cross-resistance between alkylating agents has not been observed, we attempt in a prospective trial to determine the advantages, if any, in administering three alkylating agents sequentially, alternately, or concurrently. A patient with myeloma, showing progressive shortening of M-protein doubling time from 98 to 15 days, developed an acute terminal phase, characterized by fever and pancytopenia. A similar acute terminal phase was observed in 17 of 50 deaths from myeloma. Since alkylating agents are only effective in controlling the chronic phase of myeloma, future improvements will require the discovery of agents that delay, prevent, or are effective in the treatment of the acute phase. Forty-five patients with kappa- and 36 with lambda-light-chain disease showed no differences in frequency of amyloidosis, renal failure, response to treatment, or survival after treatment with alkylating agents.

Bence Jones proteins and light chains of immunoglobulins. XI. A transient Bence Jones-related protein associated with corticosteroid therapy.
    The Journal of clinical investigation, 1975, Volume: 55, Issue:3

    Urine specimens from patients with multiple myeloma and Bence Jones proteinuria frequently contain low molecular weight proteins which correspond either to the amino-terminal, variant half (VL) or to the carboxyl-terminal, constant half (CL) of the Bence Jones protein. Analyses of urine specimens from such patients who had received high doses of corticosteroids as part of their treatment regimen revealed that concomitantly with a decrease in Bence Jones protein excretion was the appearance of a low molecular weight protein related to the Bence Jones protein but not identical to the VL or to the CL. Analyses of daily urine specimens obtained from one such patient over an extended time period revealed that a reproducible chain of events occurred during a treatment regimen which included oral administration of 75 mg of prednisone daily for 7 consecutive days. The amount of Bence Jones protein excreted decreased progressively, and by the 5th day was usually less than 10% of the pretreatment value. The urine specimen obtained on the 6th day of treatment was virtually devoid of Bence Jones protein but contained a newly appearing protein whose electrophoretic mobility was distinct from that of the Bence Jones protein or its VL or CL. Cessation of corticosteroid therapy resulted in a prompt disappearance of the new protein and in a progressive increase in the amount of Bence Jones protein excreted. The new protein was isolated from the urine of this patient and was purified for comparative studies with Bence Jones protein and with the VL and CL prepared by specific enzymatic cleavage of the Bence Jones protein. These studies revealed that the new protein was most related antigenically to the CL, but could be distinguished immunochemically from the CL. This new protein, a component found in vivo related to the constant half of the light polypeptide chain, was designated CL, and was structurally 25 amino acid residues longer than the CL, that is, the amino-terminus of the enzymatically prepared CL was at position 117 whereas that of the transitory new Bence Jones-related protein was at position 92 of the light polypeptide chain. Biosynthetic studies were performed with plasma cells derived from the bone marrow of this patient at a time when both the CL and the Bence Jones protein were being excreted; both proteins were identified in extracellular culture fluid by immunochemical techniques. Whether the CL is of synthetic or catabolic origin is presently not known; h

    Fifteen cases of multiple myeloma and 6 cases of macroglobulin emia Waldenstrom were followed up from 1957 to 1974. As for administration of drugs a low continuous dose regimen was mainly employed instead of a high intermittent dose regimen. 50% survival time from the onset of the disease was 18 months for multiple myeloma and 25 months for macroglobulinemia Waldenstrom. 3 cases of multiple myeloma are still living 44 months after the onset of symptoms. Cyclophosphamide and melphalan seem to have contributed much to the prolonged survival of these patients as well as improved supportive care.

Multiple myeloma and acute leukemia associated with alkylating agents.
    Archives of internal medicine, 1975, Volume: 135, Issue:1

    Rapidly fatal acute myelomonocytic leukemia developed in five patients with multiple myeloma who were treated with melphalan for 28 to 54 months. In each patient, multiple myeloma responded to therapy and progress was satisfactory until the development of acute leukemia. At postmortem examination, leukemic infiltration of organs was seen, and there was little or no evidence of myeloma. Consideration of these cases and a review of the literature suggest that these circumstances represent the development of acute myelomonocytic leukemia rather than plasma cell leukemia; there also appears to be an increased incidence of acute leukemia in multiple myeloma, probably related to the alkylating agent.

The monoclonal nature of lymphocytes in multiple myeloma. Effects of therapy.
    Annals of internal medicine, 1975, Volume: 83, Issue:1

    Despite the increased amounts of serum immumoglobulins (Ig) in multiple myeloma, the percentage of bone marrow-dependent (B) cells carrying surface Ig in the peripheral blood compartment were decreased, when compared with that in control patients with polyclonal gammopathy or with that in normals (5 plus or minus 2% in patients with multiple myeloma and 19 plus or minus 5% or 22 plus or minus 7% in controls). Most circulating B cells in patients with multiple myeloma were shown to carry individually specific idiotypic Ig. The monoclonal idiotypic nature of the surface Ig was shown by using antiserums raised against the monoclonal Ig. The idiotypic antiserum was capable of actively binding to and stimulating the idiotypic lymphocytes to divide in vitro. Commercial anti-Ig antiserums raised against normal Ig did not bind to the myeloma lymphocytes. After chemotherapy, lymphocytes carrying the idiotypic Ig decreased in numbers, and this correlated with other variables of clinical improvements. Its role in the pathogenesis of myeloma and its importance for diagnosis and follow-up of patients with myeloma are discussed.

Chromosome studies in acute leukemias developing in patients with multiple myeloma.
    Cancer research, 1975, Volume: 35, Issue:10

    Chromosomal findings are reported in three patients with acute myelomonocytic leukemia and in one with reticulosarcoma leukemia who had been treated for multiple myeloma with melphalan and X-ray. All four patients had striking chromosomal anomalies. An iatrogenic causation of aneuploidy is suggested. This is supported by chromosomal findings in patients with acute leukemia following polycythemia vera and Hodgkin's disease; practically all of the leukemias have been aneuploid. A comparison is made of such "secondary" acute leukemias with "primary" acute leukemias that are aneuploid in only 40% of the cases. Chromosomal changes are not considered to be the initial event in leukemogenesis.

Monitoring myelomatosis.
    Archives of internal medicine, 1975, Volume: 135, Issue:1

    There is evidence for the value of the following tests in the diagnosis, monitoring, and prognosis of myelomatosis: (1) serum paraprotein measurements, (2) urine paraprotein (including Bence Jones) measurements, (3) serum ablumin, (4) serum urea, (5) proteins in the urine other than those in 2, and (6) hemoglobin level. During treatment, increased rate of rise in 1 or 2, disproportionate increase in 2, emergence of related paraprotein, loss of 1 or 2 with reticulosarcomatous change, and monocytic leukemia suggest that more malignant subclones can emerge from the original myeloma clone, possibly due to drugs acting on DNA.

Clinical classification of plasma cell myeloma.
    Archives of internal medicine, 1975, Volume: 135, Issue:1

    Clinical and electrophoretic data were evaluated in 334 consecutive patients with myeloma or monoclonal peaks on serum or urine electrophoresis. Of the 242 patients with myeloma, 7% had localized plasmacytomas with absent or low level monoclonal peaks on electrophoresis and received only radiotherapy to focal disease areas. Chemotherapy was also withheld from eight other patients in an indolent clinical phase of multiple myeloma. Disease progression was apparent in about one third of the patients with localized and indolent myeloma within 12 months. Forty-three patients had idiopathic peaks on serum electrophoresis; more than 90% were of the IgG type with levels less than 3.0 gm/100 ml. Serial elecrtophoreses, immunoglobulin quantitations, and skeletal radiographs are recommended for the evaluation of patients with idiopathic peaks, the classification of early phases of myeloma, and the confirmation of tumor mass change.

Evaluation of a cooperative group human myeloma protocol using the MOPC 104E myeloma model.
    Cancer research, 1975, Volume: 35, Issue:5

    Data are presented on the response rates, maximum rate of cell kill, and survival rates for individual and groups of mice with MOPC 104E myeloma treated with a variety of chemotherapeutic agents and combination regimens used in clinical human myeloma. The tumor immunoglobulin M measurements are used to evalutae the therapeutic effects of drugs. Prednisolone and mescaline, when given as single drugs, showed no therapeutic action and the animals died of tumor as in the controls. The immunoglobulin M values are very similar and ranged between 8,125 and 13,410 mug/mouse. Prednisolone and melphalan given in combination indicated therapeutic effect. 1,3-Bis(2-chloroethyl)-1-nitrosourea-cyclophosphamide-prednisolone combination caused tumor regression but was toxic as shown by the immunoglobulin M values and percentage of survival. The complications and potential uses of this system, which utilized only 40 animals in 64 days, are discussed.

Pseudomyeloma. Is association of severe osteoporosis with serum monoclonal gammopathy an entity or a coincidence?
    Archives of internal medicine, 1975, Volume: 135, Issue:2

    The designation "pseudomyeloma'' is used to describe three patients who had a clinical picture that closely resembled multiple myeloma and was characterized by severe osteoporosis and a serum monoclonal paraprotein peak. The diagnosis of myeloma could not be made histologically, initally or after three, four, or ten years of observation. The protein abnormalities and the bone marrow picture remained stable. It is not known if this association has pathophysiologic importance or if it represents a chance phenomenon.

Plasma cells in urine: occurrence in multiple myeloma.
    Archives of internal medicine, 1975, Volume: 135, Issue:9

    Numerous plasma cells were transiently found in the urine of a patient with multiple myeloma. The patient was in acute renal failure, and she had K-type Bence-Jones proteinemia and proteinuria. A slide of stained urine sediment showed cells with freatures characteristic of plasma cells. Their cytoplasm was highly reactive with anti-K antiserum on immunofluorescence, suggesting that these were myeloma cells.

Chromosomal abnormalities and dyserythropoiesis in the preleukaemic phase of multiple myeloma.
    British journal of haematology, 1975, Volume: 31, Issue:1

    Two patients with multiple myeloma and one patient with a plasma-cytoma are reported in whom acute leukaemia developed following long-term treatment with melphalan. Each patient had a complete remission of the plasma cell disorder during which time the bone marrow was moderately to severely hypoplastic. The end of the clinical remission was heralded by a dyserythropoietic anaemia which persisted several months before the emergence of the terminal acute leukaemia. Marked chromosomal abnormalities were observed in marrow cells during the dyserythropoietic phase.

Plasma cell myeloma: response of melphalan-resistant patients to high-dose intermittent cyclophosphamide.
    Canadian Medical Association journal, 1972, Nov-04, Volume: 107, Issue:9

    High-dose intermittent cyclophosphamide was used in the treatment of 19 patients with plasma cell myeloma who had demonstrated resistance to melphalan. Good objective improvement was found in six patients and partial responses in five. Patients have survived from three to more than 36 months (estimated median 21 months) after starting cyclophosphamide, and 11 are still alive. The important implications of the lack of cross-resistance between these two alkylating agents are discussed in terms of the mechanisms of cellular resistance to alkylating agents.

Kinetics of tumor growth and regression in IgG multiple myeloma.
    The Journal of clinical investigation, 1972, Volume: 51, Issue:7

    Studies of immunoglobulin synthesis, total body tumor cell number, and tumor kinetics were carried out in a series of patients with IgG multiple myeloma. The changes in tumor size associated with tumor growth or with regression were underestimated when the concentration of serum M-component was used as the sole index of tumor mass. Calculation of the total body M-component synthetic rate (corrected for concentration-dependent changes in IgG metabolism) and tumor cell number gave a more accurate and predictable estimate of changes in tumor size. Tumor growth and drug-induced tumor regression were found to follow Gompertzian kinetics, with progressive retardation of the rate of change of tumor size in both of these circumstances. This retardation effect, describable with a constant alpha, may be caused by a shift in the proportion of tumor cells in the proliferative cycle. Drug sensitivity of the tumor could be described quantitatively with a calculation of B(O), the tumor's initial sensitivity to a given drug regimen. Of particular clinical significance, the magnitude of a given patient's tumor regression could be predicted from the ratio of B(O) to alpha. Mathematical proof was obtained that the retardation constant determined during tumor regression also applied to the earlier period of tumor growth, and this constant was used to reconstruct the preclinical history of disease. In the average patient, fewer than 5 yr elapse from the initial tumor cell doubling to its clinical presentation with from 10(11) to more than 10(12) myeloma cells in the body. The reduction in total body tumor mass in most patients responding to therapy ranges from less than one to almost two orders of magnitude. Application of predictive kinetic analysis to the design of sequential drug regimens may lead to further improvement in the treatment of multiple myeloma and other tumors with similar growth characteristics.

Multiple myeloma. Clinical correlation of immunoglobulin changes with therapy. A report of 23 cases.
    California medicine, 1969, Volume: 110, Issue:1

    Twenty-three patients with multiple myeloma were studied. They were grouped according to their clinical response and changes in myeloma globulin in the serum or urine while under chemotherapy. Sixteen responded favorably with clinical improvement and marked reduction in the respective M-globulins. Four did not respond and showed progression of disease, and three had short-lived clinical response with essentially unchanged myeloma-globulin values. Patients with renal insufficiency showed simultaneous improvement of uremia and M-globulins in response to chemotherapy. Three patients had solitary plasmacytomas when first seen, and dissemination occurred later in one. Combination of alkylating agents with steroids appeared to give faster, longer-lasting and more satisfactory clinical remissions, although the bone marrow may remain essentially unchanged. Radiation therapy was the most effective agent against localized pain (without altering the M-globulin) when used alone. Twenty-two of the 23 patients already had a significant decrease in IgM at the time multiple myeloma was diagnosed. A diminution in IgM can be considered of diagnostic significance although the mechanism for this reduction is not known. It has been felt to involve a feed-back mechanism, where one immunoglobulin elevation results in a subsequent diminution in the other immunoglobulins.
