Waldenström macroglobulinemia is defined by the presence of monoclonal immunoglobulin IgM type (M-IgM) and evidence of lymphoplasmacytic bone marrow infiltration. The disease has an indolent course, the treatment is only initiated when the disease has begun to damage its carrier. The following symptoms are regarded as proven indications for initiating therapy: B symptoms, symptomatic lymphadenopathy, splenomegaly, anemia with hemoglobin below 100 g / l or thrombocytopenia < 100 × 10(9)/l, caused by lymphoplasmacytic bone marrow infiltration. Frequent indications for initiating treatment include clinical evidence of hyperviscosity or cryoglobulinemia. M-IgM tends to have a character of autoantibody reaching up to 50 %, which may harm the organism, and therefore any proven damage to the organism by an autoimmune activity of M-IgM is also an indication for treatment. The text includes an overview of rare and very rare types of damage to the organism by M-IgM autoimmune activity. A combination of rituximab, cyclophosphamide and dexamethasone (RCD) is recommended for the initial treatment, possibly extended to R-CHOP regimen (rituximab, cyclophosphamide, vincristine, doxorubicin and prednisone). In our cohort of 43 patients the therapy involving a combination of R-CHOP achieved 3 (8.1 %) complete remissions and 31 (83.8 %) partial remissions. The remission in 75 % of the patients lasted more than 3 years. In case of recurrence after > 2 years, the same therapy can be used, in case of a relapse within a shorter period of time different treatment schedules are recommended. High-dose chemotherapy with an autologous transplant of stem cells obtained from peripheral blood is only recommended after the first recurrence for people under 65 years of age without contraindications. The text analyses the benefits of the new drugs for the treatment of Waldenström macroglobulinemia (bendamustine, thalidomide, lenalidomide, ibrutinib and high-dose chemotherapy).

At least four doses of quinine followed by a single dose of mefloquine or by a single dose of sulfadoxine-pyrimethamine are two highly effective regimens for chloroquine-resistant falciparum malaria. Mefloquine alone is valuable in ambulant patients. Chloroquine-sensitive falciparum malaria can be treated with a course of chloroquine. Vivax and all other types of malaria should be treated with sequential chloroquine and primaquine. Quinine, by intravenous infusion, is the most effective drug for severe falciparum malaria. The optimum intravenous dose varies between 5 mg/kg and 10 mg/kg administered over four hours. Intravenous or oral quinine should be administered about every 12 hours and the total daily dose of quinine should rarely exceed 20 mg/kg. Intravenous fluid input should be controlled in falciparum malaria to prevent pulmonary oedema. Established renal failure is best treated by dialysis. The value of adrenocortical steroids for falciparum coma has not been established. Fresh blood transfusion may be helpful in small doses for severe anaemia and to replace clotting factors. Anticoagulants, such as heparin, should not be used in falciparum malaria.

Ibrutinib, a first-in-class once-daily oral Bruton tyrosine kinase inhibitor indicated for chronic lymphocytic leukemia (CLL), is continued until progressive disease or unacceptable toxicity. We conducted an integrated safety analysis of single-agent ibrutinib from randomized phase 3 studies PCYC-1112 (RESONATE, n = 195) and PCYC-1115/1116 (RESONATE-2, n = 135), and examined longer-term safety separately in the phase 1b/2 PCYC-1102/1103 study (n = 94, 420 mg/d). In the integrated analysis (ibrutinib treatment up to 43 months), the most common adverse events (AEs) were primarily grade 1/2; diarrhea (n = 173, 52% any-grade; n = 15, 5% grade 3) and fatigue (n = 119, 36% any-grade; n = 10, 3% grade 3). The most common grade 3/4 AEs were neutropenia (n = 60, 18%) and pneumonia (n = 38, 12%). Over time, prevalence of AEs of interest (diarrhea, fatigue, grade ≥3 infection, bleeding, and neutropenia) trended down; prevalence of hypertension increased, but incidence decreased after year 1. AEs led to dose reductions in 42 (13%) patients and permanent discontinuations in 37 (11%); dose modifications due to AEs were most common during year 1 and decreased in frequency thereafter. The most common AEs (preferred term) contributing to discontinuation included pneumonia (n = 4), anemia (n = 3), and atrial fibrillation (n = 3). With long-term follow-up on PCYC-1102/1103 (ibrutinib treatment up to 67 months), grade 3/4 AEs were generally similar to those in the integrated analysis. Overall, AEs were primarily grade 1/2 and manageable during prolonged ibrutinib treatment in patients with CLL. These trials were registered at www.clinicaltrials.gov as #NCT01578707, #NCT01722487, #NCT01724346, #NCT01105247, and #NCT01109069.

Marginal zone lymphoma (MZL) is a heterogeneous B-cell malignancy for which no standard treatment exists. MZL is frequently linked to chronic infection, which may induce B-cell receptor (BCR) signaling, resulting in aberrant B-cell survival and proliferation. We conducted a multicenter, open-label, phase 2 study to evaluate the efficacy and safety of ibrutinib in previously treated MZL. Patients with histologically confirmed MZL of all subtypes who received ≥1 prior therapy with an anti-CD20 antibody-containing regimen were treated with 560 mg ibrutinib orally once daily until progression or unacceptable toxicity. The primary end point was independent review committee-assessed overall response rate (ORR) by 2007 International Working Group criteria. Among 63 enrolled patients, median age was 66 years (range, 30-92). Median number of prior systemic therapies was 2 (range, 1-9), and 63% received ≥1 prior chemoimmunotherapy. In 60 evaluable patients, ORR was 48% (95% confidence interval [CI], 35-62). With median follow-up of 19.4 months, median duration of response was not reached (95% CI, 16.7 to not estimable), and median progression-free survival was 14.2 months (95% CI, 8.3 to not estimable). Grade ≥3 adverse events (AEs; >5%) included anemia, pneumonia, and fatigue. Serious AEs of any grade occurred in 44%, with grade 3-4 pneumonia being the most common (8%). Rates of discontinuation and dose reductions due to AEs were 17% and 10%, respectively. Single-agent ibrutinib induced durable responses with a favorable benefit-risk profile in patients with previously treated MZL, confirming the role of BCR signaling in this malignancy. As the only approved therapy, ibrutinib provides a treatment option without chemotherapy for MZL. This study is registered at www.clinicaltrials.gov as #NCT01980628.

Most patients with chronic lymphocytic leukaemia or small lymphocytic lymphoma relapse after initial therapy. Bendamustine plus rituximab is often used in the relapsed or refractory setting. We assessed the efficacy and safety of adding ibrutinib, an oral covalent inhibitor of Bruton's tyrosine kinase (BTK), to bendamustine plus rituximab in patients with previously treated chronic lymphocytic leukaemia or small lymphocytic lymphoma.. The HELIOS trial was an international, double-blind, placebo-controlled, phase 3 study in adult patients (≥18 years of age) who had active chronic lymphocytic leukaemia or small lymphocytic lymphoma with measurable lymph node disease (>1·5 cm) by CT scan, and had relapsed or refractory disease following one or more previous lines of systemic therapy consisting of at least two cycles of a chemotherapy-containing regimen, an Eastern Cooperative Oncology Group (ECOG) performance status of 0-1, and adequate bone marrow, liver, and kidney function. Patients with del(17p) were excluded because of known poor response to bendamustine plus rituximab. Patients who had received previous treatment with ibrutinib or other BTK inhibitors, refractory disease or relapse within 24 months with a previous bendamustine-containing regimen, or haemopoietic stem-cell transplant were also excluded. Patients were randomly assigned (1:1) by a web-based system to receive bendamustine plus rituximab given in cycles of 4 weeks' duration (bendamustine: 70 mg/m(2) intravenously on days 2-3 in cycle 1, and days 1-2 in cycles 2-6; rituximab: 375 mg/m(2) on day 1 of cycle 1, and 500 mg/m(2) on day 1 of cycles 2-6 for a maximum of six cycles) with either ibrutinib (420 mg daily orally) or placebo until disease progression or unacceptable toxicity. Patients were stratified according to whether they were refractory to purine analogues and by number of previous lines of therapy. The primary endpoint was independent review committee (IRC)-assessed progression-free survival. Crossover to ibrutinib was permitted for patients in the placebo group with IRC-confirmed disease progression. Analysis was by intention-to-treat and is continuing for further long-term follow-up. The trial is registered with ClinicalTrials.gov, number NCT01611090.. Between Sept 19, 2012, and Jan 21, 2014, 578 eligible patients were randomly assigned to ibrutinib or placebo in combination with bendamustine plus rituximab (289 in each group). The primary endpoint was met at the preplanned interim analysis (March 10, 2015). At a median follow-up of 17 months (IQR 13·7-20·7), progression-free survival was significantly improved in the ibrutinib group compared with the placebo group (not reached in the ibrutinib group (95% CI not evaluable) vs 13·3 months (11·3-13·9) in the placebo group (hazard ratio [HR] 0·203, 95% CI 0·150-0·276; p<0·0001). IRC-assessed progression-free survival at 18 months was 79% (95% CI 73-83) in the ibrutinib group and 24% (18-31) in the placebo group (HR 0·203, 95% CI 0·150-0·276; p<0·0001). The most frequent all-grade adverse events were neutropenia and nausea. 222 (77%) of 287 patients in the ibrutinib group and 212 (74%) of 287 patients in the placebo group reported grade 3-4 events; the most common grade 3-4 adverse events in both groups were neutropenia (154 [54%] in the ibrutinib group vs 145 [51%] in the placebo group) and thrombocytopenia (43 [15%] in each group). A safety profile similar to that previously reported with ibrutinib and bendamustine plus rituximab individually was noted.. In patients eligible for bendamustine plus rituximab, the addition of ibrutinib to this regimen results in significant improvements in outcome with no new safety signals identified from the combination and a manageable safety profile..

To document fetal stress hormone and Doppler changes after intrauterine transfusions (IUTs) in either the intrahepatic portion of the umbilical vein (IHV) or the placental cord insertion (PCI).. Pregnant women scheduled for IUT for fetal anemia (N = 25) were included prospectively. Cortisol, β-endorphin and noradrenalin concentrations in fetal plasma and middle cerebral artery pulsatility index before and after transfusion were compared. Transfusions were performed through the (IHV), thus puncturing the fetus, or at the PCI.. There were no measurable differences between the transfusion sites.. In anemic fetuses undergoing transfusion, Doppler changes and fetal stress hormone changes were unrelated to the site of needle insertion.

To establish the maximum tolerated dose of lonafarnib, a novel farnesyltransferase inhibitor, in combination with paclitaxel in patients with solid tumors and to characterize the safety, tolerability, dose-limiting toxicity, and pharmacokinetics of this combination regimen.. In a Phase I trial, lonafarnib was administered p.o., twice daily (b.i.d.) on continuously scheduled doses of 100 mg, 125 mg, and 150 mg in combination with i.v. paclitaxel at doses of 135 mg/m(2) or 175 mg/m(2) administered over 3 h on day 8 of every 21-day cycle. Plasma paclitaxel and lonafarnib concentrations were collected at selected time points from each patient.. Twenty-four patients were enrolled; 21 patients were evaluable. The principal grade 3/4 toxicity was diarrhea (5 of 21 patients), which was most likely due to lonafarnib. dose-limiting toxicities included grade 3 hyperbilirubinemia at dose level 3 (100 mg b.i.d. lonafarnib and 175 mg/m(2) paclitaxel); grade 4 diarrhea and grade 3 peripheral neuropathy at dose level 3A (125 mg b.i.d. lonafarnib and 175 mg/m(2) paclitaxel); and grade 4 neutropenia with fever and grade 4 diarrhea at level 4 (150 mg b.i.d. lonafarnib and 175 mg/m(2) paclitaxel). The maximum tolerated dose established by the continual reassessment method was lonafarnib 100 mg b.i.d. and paclitaxel 175 mg/m(2). Paclitaxel appeared to have no effect on the pharmacokinetics of lonafarnib. The median duration of therapy was eight cycles, including seven cycles with paclitaxel. Six of 15 previously treated patients had a durable partial response, including 3 patients who had previous taxane therapy. Notably, two of five patients with taxane-resistant metastatic non-small cell lung cancer had partial responses.. When combined with paclitaxel, the recommended dose of lonafarnib for Phase II trials is 100 mg p.o. twice daily with 175 mg/m(2) of paclitaxel i.v. every 3 weeks. Additional studies of lonafarnib in combination regimens appear warranted, particularly in patients with non-small cell lung cancer.

We reviewed haematological investigations for 43 patients treated at a single centre with alectinib, an inhibitor of anaplastic lymphoma kinase (ALK) which is considered standard first-line treatment for patients with ALK-rearranged advanced non-small cell lung cancer. Ninety-five percent of patients developed marked acanthocytosis, echinocytosis and/or spheroacanthocytosis, not observable with prior treatment with other ALK-inhibitors. Anaemia developed in 73% of patients (38% <100 g/L, 8% <80 g/L), though definite new haemolysis was present in only 11%. Eosin-5-maleimide binding was reduced in all assessed patients, and increased membrane cholesterol was identified in one patient assessed with lattice light sheet microscopy. We have identified a previously undescribed phenomenon whereby alectinib induces red cell membrane abnormalities in nearly all patients through an unclear, but likely ALK-independent, mechanism, resulting in mild anaemia without universal haemolysis.

The development of enhanced recovery after surgery (ERAS) protocols for patients undergoing radical cystectomy (RC) represents a significant advance in perioperative care.. To evaluate gastrointestinal (GI) complications following RC and urinary diversion (UD) using our institutional ERAS protocol.. We identified 377 consecutive cases of open RC and UD for which our ERAS protocol was used from May 2012 to December 2015. Exclusion criteria were consent refusal; non-bladder primary disease; palliative, salvage, or additional surgery; and prolonged postoperative intubation. A matched cohort of 144 patients for whom a traditional postoperative protocol (pre-ERAS) was used between 2003 and 2012 was selected for comparison.. A total of 292 ERAS patients with median age of 70 yr were included in the study, 65% of whom received an orthotopic neobladder. The median time to first flatus and bowel movement was 2 d. The median length of stay was 4 d. GI complications occurred in 45 patients (15.4%) during the first 30 d following RC, 93% of which were of minor grade. The most common GI complication was postoperative ileus (POI) in 34 cases (11.6%). Some 22 patients (7.5%) required a nasogastric tube, and parenteral nutrition was required in three patients. The rate of 30-d GI complications was significantly lower in the ERAS cohort than in the control group (13% vs 27%; p=0.003), as was the rate of POI (7% vs 23%; p<0.001). This effect was independent of other variables (hazard ratio 0.38, 95% confidence interval 0.18-0.82; p=0.01).. Our institutional ERAS protocol for RC is associated with significantly improved perioperative GI recovery and lower rates of GI complications. This protocol can be tested in multi-institutional studies to reduce GI morbidity associated with RC.. In this study, we showed that an enhanced recovery protocol for patients undergoing radical cystectomy for bladder cancer was associated with a significantly shorter length of hospital stay and lower rates of gastrointestinal complications, especially postoperative ileus.

Ibrutinib shows superiority over obinutuzumab with chlorambucil (G-Clb) in untreated patients with chronic lymphocytic leukemia with comorbidities who cannot tolerate fludarabine-based therapy. However, ibrutinib is relatively more expensive than G-Clb. In this study we evaluated the cost-effectiveness of ibrutinib compared with G-Clb from the United Kingdom (UK) health care perspective.. A 3-state semi-Markov model was parameterized to estimate the lifetime costs and benefits associated with ibrutinib compared with G-Clb as first-line treatment. Idelalisib with rituximab was considered as second-line treatment. Unit costs were derived from standard sources, (dis)utilities from UK elicitation studies, progression-free survival, progression, and death from clinical trials, and postprogression survival and background mortality from published sources. Additional analyses included threshold analyses with ibrutinib and idelalisib at various discount rates, and scenario analysis with ibrutinib as second-line treatment after G-Clb.. An average gain of 1.49 quality-adjusted life-years (QALYs) was estimated for ibrutinib compared with G-Clb at an average additional cost of £112,835 per patient. To be cost-effective as per the UK thresholds, ibrutinib needs to be discounted at 30%, 40%, and 50% if idelalisib is discounted at 0%, 25%, and 50% respectively. The incremental cost-effectiveness ratio was £75,648 and £-143,279 per QALY gained for the base-case and scenario analyses, respectively. Sensitivity analyses showed the robustness of the results.. As per base-case analyses, an adequate discount on ibrutinib is required to make it cost-effective as per the UK thresholds. The scenario analysis substantiates ibrutinib's cost-savings for the UK National Health Services and advocates patient's access to ibrutinib in the UK.

Poly(ADP-ribose) polymerase (PARP) proteins are used by cells in several DNA repair processes. PARP inhibition can result in preferential death of cancer cells when another mechanism for repairing DNA is defective. Two PARP inhibitors, olaparib and rucaparib, have been approved by the US Food and Drug Administration (FDA) for the treatment of recurrent, BRCA-associated ovarian cancer. More recently, these two and a third PARP inhibitor, niraparib, were approved by the FDA as maintenance therapy following platinum-based chemotherapy for recurrent ovarian cancer. This has caused a paradigm shift in disease management and a challenge for clinicians, who must decide how best to use these agents in individualized treatment. The oral formulation is attractive to patients, but adverse effects such as nausea and fatigue can impact quality of life. As clinicians become comfortable selecting PARP inhibitors and managing associated toxicities, future steps will be to investigate how to safely administer them in combination with other therapies.

Anemia is considered as one of the most frequent hematological demonstration of malignant diseases, which lead to momentous impairment in every tissues and organs of cancer patients and put them under serious stress. This major problem may arise because of the underlining diseases (i.e., cancer diseases) or radiotherapy or chemotherapy treatment received. This present study tries to find the association between anemia onset and severity with different chemotherapeutics regimens used in the treatment of several solid cancers and to find the association of anemia onset and severity with different doses of these chemotherapeutics drugs.. This retrospective observational study was conducted in Penang General Hospital on 534 anemic solid cancer patients who were admitted between 2003 and 2009. The main statistical tests used were Chi-square test and Logistic regression test for categorical data. While for continues data the main statistical tests were Linear regression and correlation test. The significance of the result will be when the P<0.05, while the confidence interval for this study was 95%.. FEC, 5-FU+5-FU, Docetaxel and Cisplatin+ 5-FU regimen has strong association and correlation with anemia onset and severity. However the associations and correlations with anemia severity were stronger than those with the onset. Different doses of 5-FU, cyclophosphamide, docetaxel and cisplatin play a critical role in anemia onset and severity.. Monitoring and determination of hemoglobin levels for cancer patients treated with FEC, 5-FU+5-FU, Docetaxel, Cisplatin+ 5-FU specifically with high doses must be emphasized and a focus of particular attention.
