melphalan and Liver-Neoplasms

Regional therapies for primary and secondary liver tumors have garnered interest in recent years and several types of treatment approaches have been pursued to control disease, palliate symptoms, and extend survival. Chemosaturation is an innovative way to deliver high-dose chemotherapy to the liver via the hepatic artery. Within the last decade, "isolated hepatic perfusion" (IHP) has evolved from an open surgical approach to a minimally invasive procedure, now termed "chemosaturation" (CS) with "percutaneous hepatic perfusion (PHP)". The most conclusive data on CS-PHP is currently available for patients with hepatic metastases from uveal melanoma (UM) - a rare but devastating disease with a poor long-term survival rate. A global phase-3 study and several cohort studies have provided compelling evidence that CS-PHP is an effective salvage treatment for liver-dominant metastatic UM in institutions with appropriate expertise. In this review we provide an overview on the technique, available clinical data, including safety and efficacy, and potential indications for CS-PHP.

The most effective way to control severity and mortality rate of the novel coronavirus disease (COVID-19) is through sensitive diagnostic approaches and an appropriate treatment protocol. We aimed to identify the effect of adding corticosteroid and Tocilizumab to a standard treatment protocol in treating COVID-19 patients with chronic disease through hematological and lab biomarkers.. This study was performed retrospectively on 68 COVID-19 patients with chronic disease who were treated by different therapeutic protocols. The patients were categorized into four groups: control group represented the patients' lab results at admission before treatment protocols were applied; group 1 included patients treated with anticoagulants, Hydroxychloroquine, and antibiotics; group 2 comprised patients treated with Dexamethasone; and group 3 included patients treated with Dexamethasone and Tocilizumab.. The study paves the way into the effectiveness of combining Dexamethasone with Tocilizumab in treatment COVID-19 patients with chronic diseases.. La forma más eficaz de controlar la gravedad y la tasa de mortalidad de la enfermedad del nuevo coronavirus (COVID-19) es mediante enfoques de diagnóstico sensibles y un protocolo de tratamiento adecuado. Nuestro objetivo fue identificar el efecto de agregar corticosteroides y tocilizumab a un protocolo de tratamiento estándar en el tratamiento de pacientes con COVID-19 con enfermedad crónica a través de biomarcadores hematológicos y de laboratorio.. Este estudio se realizó de forma retrospectiva en 68 pacientes COVID-19 con enfermedad crónica que fueron tratados por diferentes protocolos terapéuticos. Los pacientes se clasificaron en cuatro grupos: el grupo de control representaba los resultados de laboratorio de los pacientes en el momento de la admisión antes de que se aplicaran los protocolos de tratamiento; el grupo 1 incluyó a pacientes tratados con anticoagulantes, hidroxicloroquina y antibióticos; el grupo 2 estaba compuesto por pacientes tratados con dexametasona; y el grupo 3 incluyó a pacientes tratados con dexametasona y tocilizumab.. El estudio allana el camino hacia la eficacia de la combinación de dexametasona con tocilizumab en el tratamiento de pacientes con COVID-19 con enfermedades crónicas.. The Child-Mother Index constitutes a potential useful risk factor indicator for statistical analyses on data after birth. The value of the Child-Mother Index based on the estimated fetal weight before birth deserves evaluation.. Six ceria supports synthesized by various synthesis methodologies were used to deposit cobalt oxide. The catalysts were thoroughly characterized, and their catalytic activity for complete methane oxidation was studied. The supports synthesized by direct calcination and precipitation with ammonia exhibited the best textural and structural properties as well as the highest degree of oxidation. The remaining supports presented poorer textural properties to be employed as catalytic supports. The cobalt deposited over the first two supports presented a good dispersion at the external surface, which induced a significant redox effect that increased the number of Co. Some studies show that children with obesity are more likely to receive a diagnosis of depression, anxiety, or attention-deficit hyperactivity disorder (ADHD). But this does not necessarily mean obesity causes these conditions. Depression, anxiety, or ADHD could cause obesity. A child's environment, including family income or their parents' mental health, could also affect a child's weight and mental health. Understanding the nature of these relationships could help scientists develop better interventions for both obesity and mental health conditions. Genetic studies may help scientists better understand the role of the environment in these conditions, but it's important to consider both the child's and their parents’ genetics in these analyses. This is because parents and children share not only genes, but also environmental conditions. For example, families that carry genetic variants associated with higher body weight might also have lower incomes, if parents have been affected by biases against heavier people in society and the workplace. Children in these families could have worse mental health because of effects of their parent’s weight, rather than their own weight. Looking at both child and adult genetics can help disentangle these processes. Hughes et al. show that a child's own body mass index, a ratio of weight and height, is not strongly associated with the child’s mental health symptoms. They analysed genetic, weight, and health survey data from about 41,000 8-year-old children and their parents. The results suggest that a child's own BMI does not have a large effect on their anxiety symptoms. There was also no clear evidence that a child's BMI affected their symptoms of depression or ADHD. These results contradict previous studies, which did not account for parental genetics. Hughes et al. suggest that, at least for eight-year-olds, factors linked with adult weight and which differ between families may be more critical to a child's mental health than a child’s own weight. For older children and adolescents, this may not be the case, and the individual’s own weight may be more important. As a result, policies designed to reduce obesity in mid-childhood are unlikely to greatly improve the mental health of children. On the other hand, policies targeting the environmental or societal factors contributing to higher body weights, bias against people with higher weights, and poor child mental health directly may be more beneficial..

The management of patients with diffuse liver metastases remains a significant clinical challenge. In many cancer patients, metastatic disease may be isolated to the liver or the liver may be the dominant site of progressive metastatic cancer. In this setting, progression of disease in the liver generally is the most significant cause of morbidity and mortality.

Patients with liver metastasis from uveal melanoma have a poor prognosis. Efficacy and safety of hepatic transarterial chemoembolization (TACE) using melphalan and microspheres was evaluated.. Monocentric retrospective study of all consecutive patients treated by TACE using melphalan and 250μm calibrated microspheres between 2004 and 2016. Radiological response was assessed according to RECIST 1.1, modified (m)-RECIST and EASL on contrast-enhanced computed tomography (CT) or magnetic resonance imaging (MRI). The primary endpoint was overall survival (OS). Liver metastasis response, hepatic, extrahepatic and global progression free survival (PFS) complications were evaluated with the common terminology criteria for adverse events version 4.0 (CTCAE 4.0) and survival factors were secondary endpoints.. Thirty-four patients underwent 138 TACE (4; 4.1 sessions; range 1-9). Median OS was 16.5 months (mean 21.6 months). Liver metastasis response combining partial and complete response was 42.4%, 97%, 97% with RECIST 1.1, mRECIST, EASL, respectively. There were 58 severe (CTCAE≥3) but manageable complications in 28 patients, except for 1 toxic death.. For patients with liver metastases from uveal melanoma ineligible for local treatments, TACE using melphalan may be performed as first line therapy in metastatic miliary disease from uveal melanomas with careful supportive care.

Liver malignancies are a major burden of disease worldwide. The long-term prognosis for patients with unresectable tumors remains poor, despite advances in systemic chemotherapy, targeted agents, and minimally invasive therapies such as ablation, chemoembolization, and radioembolization. Thus, the demand for new and better treatments for malignant liver tumors remains high. Surgical isolated hepatic perfusion (IHP) has been shown to be effective in patients with various hepatic malignancies, but is complex, associated with high complication rates and not repeatable. Percutaneous isolated liver perfusion (PHP) is a novel minimally invasive, repeatable, and safer alternative to IHP. PHP is rapidly gaining interest and the number of procedures performed in Europe now exceeds 200. This review discusses the indications, technique and patient management of PHP and provides an overview of the available data.

Recombinant human tumour necrosis factor (TNF) has a selective effect on angiogenic vessels in tumours. Given that it induces vasoplegia, its clinical use has been limited to administration through isolated limb perfusion (ILP) for regionally advanced melanomas and soft tissue sarcomas of the limbs. When combined with the alkylating agent melphalan, a single ILP produces a very high objective response rate. In melanoma, the complete response (CR) rate is around 80% and the overall objective response rate greater than 90%. In soft tissue sarcomas that are inextirpable, ILP is a neoadjuvant treatment resulting in limb salvage in 80% of the cases. The CR rate averages 20% and the objective response rate is around 80%. The mode of action of TNF-based ILP involves two distinct and successive effects on the tumour-associated vasculature: first, an increase in endothelium permeability leading to improved chemotherapy penetration within the tumour tissue, and second, a selective killing of angiogenic endothelial cells resulting in tumour vessel destruction. The mechanism whereby these events occur involves rapid (of the order of minutes) perturbation of cell-cell adhesive junctions and inhibition of alphavbeta3 integrin signalling in tumour-associated vessels, followed by massive death of endothelial cells and tumour vascular collapse 24 hours later. New, promising approaches for the systemic use of TNF in cancer therapy include TNF targeting by means of single chain antibodies or endothelial cell ligands, or combined administration with drugs perturbing integrin-dependent signalling and sensitizing angiogenic endothelial cells to TNF-induced death.

Many patients with tumors confined to the liver are not amenable for surgical resection, and an increasing number of these patients are treated by local ablation methods. Isolated hepatic perfusion is another treatment option especially suitable for patients with multiple or bulky primary or metastatic tumors. and can mediate clinical regression of advanced liver metastases. Experience with IHP is still limited to a few centers in the world because of its technical difficulties, surgery-related morbidity, and unproven efficacy. IHP remains an experimental modality restricted to specialized units dedicated to treating this difficult group of patients. Experimental animal IHP models have led us to explore new ways of improving efficacy, reducing technical difficulties, and minimizing regional and systemic toxicity. Future research should be directed to the identification of suitable biological or chemotherapeutic agents, defining clinical indications, and development of technical modifications to make it more generally applicable.

Isolated hepatic perfusion (IHP) involves a method of complete vascular isolation of the liver to allow treatment of liver tumours with toxic systemic doses. The recent clinical studies mainly employed IHP with melphalan with or without tumour necrosis factor-alpha (TNF-alpha) and mild hyperthermia. The results of these studies show that high response rates and high survival rates can be achieved by IHP. In this article, the current status, recent developments and future perspectives of IHP are discussed.

Metastatic or primary unresectable cancers confined to the liver are the sole or life-limiting component of disease for many patients with colorectal cancer, ocular melanoma, neuroendocrine tumors, or primary colangio- or hepatocellular carcinomas. Regional treatment strategies including infusional chemotherapy and local ablative therapy are under investigation, but have limitations with respect to the clinical conditions under which they can be employed. Isolated hepatic perfusion (IHP) was first clinically applied over 40 years ago, but because of its technical complexity, the attendant potential morbidity, and the lack of documented efficacy, it has not enjoyed consistent or widespread evaluation. In light of the antitumor activity with isolated limb perfusion with tumor necrosis factor (TNF) and melphalan in patients with unresectable extremity sarcoma or in transit melanoma, this regimen has been administered via IHP at several centers worldwide for patients with unresectable liver cancers. IHP with TNF and melphalan can result in significant regression of advanced refractory cancers from multiple histologies confined to the liver. Patient selection is important to ensure good results with minimal morbidity and mortality. Work to define the appropriate clinical groups is ongoing at many clinical centers.

Progressive growth of unresectable metastatic or primary malignancies confined to the liver is a significant clinical problem. Approximately 25% of patients with colorectal cancer will develop metastatic disease exclusively or largely confined to liver, the vast majority of which are not amenable to surgical resection. Despite aggressive systemic or regional chemotherapy, survival is only 12 to 18 months. More than 80% of patients with ocular melanoma develop liver metastases as the first site of recurrent disease, and death from hepatic disease progression typically occurs 2 to 7 months after diagnosis. In addition, the liver is also the preferred site of metastatic disease for gastrointestinal or pancreatic neuroendocrine tumors. A number of physiological and anatomic features of the liver make it an ideal organ for regionally directed therapy to allow dose intensification to the cancer-burdened area while reducing or eliminating unnecessary systemic toxicity. To that end, complete vascular isolation and perfusion of the liver using a recirculating extracorporeal circuit, also called isolated hepatic perfusion (IHP), has been under clinical evaluation at our institution and others. In this article, we review the current results with IHP and its potential utility in the treatment of patients with unresectable hepatic malignancies.

Metastatic or primary unresectable cancers confined to the liver are the sole or life-limiting component of disease for many patients with colorectal cancer, ocular melanoma, neuroendocrine tumors or primary colangio- or hepatocellular carcinomas. A number of regional treatment strategies including infusional chemotherapy and local ablative therapy are under clinical development and attest to the difficulty in adequately treating this condition. Isolated hepatic perfusion (IHP) was first clinically applied over 40 years ago, but because of its technical complexity, the attendant potential morbidity, and the lack of documented efficacy, it has not gained widespread application. In light of the remarkable antitumor activity with isolated limb perfusion with tumor necrosis factor (TNF) and melphalan in patients with unresectable extremity sarcoma or in transit melanoma, this regimen has been administered via IHP at several centers worldwide for unresectable liver cancers. IHP with TNF and melphalan can result in significant regression of advanced refractory cancers confined to the liver and, with additional clinical development, will most likely be a more routinely considered option for patients with this condition.

In an attempt to improve tumor response and survival among patients with colorectal cancer metastases confined to the liver, we developed an experimental (rats and pigs) and clinical isolated hepatic perfusion (IHP) technique to exploit maximally the steep dose-response relation of may anticancer drugs. In this overview we present our experimental and clinical results with mitomycin C (MMC) and melphalan (L-Pam). In rats, treatment with a four times higher maximally tolerated dose (MTD) of MMC during IHP compared to hepatic artery infusion (HAI) resulted in higher, more effective intratumoral concentrations of MMC. As a result, only in the IHP-treated rats were complete remissions observed and long-term survival achieved. Hepatotoxic side effects were minimal and transient in all animals. In the clinical phase I/II study with MMC 30 mg/m2 administered as a bolus in the isolated circuit, two of nine patients had a complete remission, with a median survival of 17 months. Four patients developed venoocclusive disease (VOD) of the liver, and as a result one patient died. Therefore we consider MMC unsuitable for further IHP studies. Meanwhile experiments in rats showed that IHP with the L-PAM MTD of 12 mg/kg was even more effective than MMC and did not cause hepatotoxic side effects. In the phase I/II dose-findings study with L-PAM in IHP, the MTD in humans was approximately 3.0 mg/kg. As in the rats, systemic toxicity was dose-limiting. The median survival of the whole group was 18 months. We have started a phase II study of L-PAM in IHP with a fixed dose of 200 mg L-PAM to determine if IHP can significantly increase the median survival and complete remission rate compared to other treatment modalities. Results from this study are expected by the end of 1997.

To report a series of cases of hepatic resection for metastatic gynecologic carcinomas.. We reviewed the records of all patients who underwent hepatic resection for metachronous liver metastases from gynecologic carcinomas at our institution from 1986 to 1996.. Twelve patients were identified with a median age of 60 years (range 30-73 years). The primary sites of carcinoma were as follows: ovary, 7 (58%); cervix, 2 (17%); endometrium, 2 (17%); and fallopian tube, 1 (8%). The median disease-free interval before the diagnosis of liver metastasis was 32 months (range 1-243 months). The types of liver resections were as follows: trisegmentectomy, 4 (33%); lobectomy, 4 (33%); segmentectomy, 3 (25%); and wedge resection, 1 (8%). To remove all visible tumor with adequate margins, additional surgery included the following: resection of a portion of the diaphragm, 5 (42%); wedge resection of the right lung, 3 (25%); resection of a portion of the pericardium, 2 (17%); and adrenalectomy, 1 (8%). One patient (8%) had pulmonary wedge resections of bilateral pulmonary metastases. There was no perioperative mortality. Ten patients (83%) received additional chemotherapy. With a median follow-up of 25 months (range 8-94 months), the median survival time is 27 months. Three patients (25%) have no evidence of tumor recurrence at 8, 17, and 38 months of follow-up. Nine patients (75%) have had tumor recurrence at a median of 12 months from the time of surgery.. Hepatic resection of metachronous metastases from gynecologic carcinomas can be performed safely and may help prolong survival in carefully selected patients.

About half of patients with metastatic uveal melanoma present with isolated liver metastasis, in whom the median survival is 6-12 months. The few systemic treatment options available only moderately prolong survival. Isolated hepatic perfusion (IHP) with melphalan is a regional treatment option, but prospective efficacy and safety data are lacking.. In this multicenter, randomized, open-label, phase III trial, patients with previously untreated isolated liver metastases from uveal melanoma were randomly assigned to receive a one-time treatment with IHP with melphalan or best alternative care (control group). The primary end point was overall survival at 24 months. Here, we report the secondary outcomes of response according to RECIST 1.1 criteria, progression-free survival (PFS), hepatic PFS (hPFS), and safety.. Ninety-three patients were randomly assigned, and 87 patients were assigned to either IHP (n = 43) or a control group receiving the investigator's choice of treatment (n = 44). In the control group, 49% received chemotherapy, 39% immune checkpoint inhibitors, and 9% locoregional treatment other than IHP. In an intention-to-treat analysis, the overall response rates (ORRs) were 40% versus 4.5% in the IHP and control groups, respectively (. IHP treatment resulted in superior ORR, hPFS, and PFS compared with best alternative care in previously untreated patients with isolated liver metastases from primary uveal melanoma.

The Child-Mother Index constitutes a potential useful risk factor indicator for statistical analyses on data after birth. The value of the Child-Mother Index based on the estimated fetal weight before birth deserves evaluation.. Six ceria supports synthesized by various synthesis methodologies were used to deposit cobalt oxide. The catalysts were thoroughly characterized, and their catalytic activity for complete methane oxidation was studied. The supports synthesized by direct calcination and precipitation with ammonia exhibited the best textural and structural properties as well as the highest degree of oxidation. The remaining supports presented poorer textural properties to be employed as catalytic supports. The cobalt deposited over the first two supports presented a good dispersion at the external surface, which induced a significant redox effect that increased the number of Co. Some studies show that children with obesity are more likely to receive a diagnosis of depression, anxiety, or attention-deficit hyperactivity disorder (ADHD). But this does not necessarily mean obesity causes these conditions. Depression, anxiety, or ADHD could cause obesity. A child's environment, including family income or their parents' mental health, could also affect a child's weight and mental health. Understanding the nature of these relationships could help scientists develop better interventions for both obesity and mental health conditions. Genetic studies may help scientists better understand the role of the environment in these conditions, but it's important to consider both the child's and their parents’ genetics in these analyses. This is because parents and children share not only genes, but also environmental conditions. For example, families that carry genetic variants associated with higher body weight might also have lower incomes, if parents have been affected by biases against heavier people in society and the workplace. Children in these families could have worse mental health because of effects of their parent’s weight, rather than their own weight. Looking at both child and adult genetics can help disentangle these processes. Hughes et al. show that a child's own body mass index, a ratio of weight and height, is not strongly associated with the child’s mental health symptoms. They analysed genetic, weight, and health survey data from about 41,000 8-year-old children and their parents. The results suggest that a child's own BMI does not have a large effect on their anxiety symptoms. There was also no clear evidence that a child's BMI affected their symptoms of depression or ADHD. These results contradict previous studies, which did not account for parental genetics. Hughes et al. suggest that, at least for eight-year-olds, factors linked with adult weight and which differ between families may be more critical to a child's mental health than a child’s own weight. For older children and adolescents, this may not be the case, and the individual’s own weight may be more important. As a result, policies designed to reduce obesity in mid-childhood are unlikely to greatly improve the mental health of children. On the other hand, policies targeting the environmental or societal factors contributing to higher body weights, bias against people with higher weights, and poor child mental health directly may be more beneficial..

Ocular melanoma is the most common primary intraocular malignancy and has a very poor prognosis once liver metastases occur. The aim of this study was to prospectively assess the efficacy and safety of percutaneous hepatic perfusion with melphalan (M-PHP) using the new second-generation (GEN 2) hemofiltration system in patients with ocular melanoma metastases confined to the liver.. Prospective, single-center, single-arm, phase II study including patients with unresectable ocular melanoma metastases confined to the liver. Treatment consisted of two M-PHP procedures at 6-8 weeks interval. Procedures were performed using the CHEMOSAT (GEN 2) system with 3 mg/kg melphalan. Primary endpoints were overall response rate (ORR) and best overall response (BOR). Secondary endpoints included overall survival (OS), progression-free survival (PFS), hepatic PFS (hPFS), and safety.. Sixty-four M-PHP procedures were performed in 35 patients between February 2014 and June 2017. The ORR was 72%. BOR was as follows: complete response in 3%, partial response in 69%, stable disease in 13%, and progressive disease in 16%. There was no treatment-related mortality. Fourteen serious adverse events occurred. At a median follow-up of 19.1 months (range 5.6-69.5), median OS was 19.1 months and was significantly longer in responders than in nonresponders (27.5 vs. 11.9 months, p < 0.001). The 1- and 2-year OS was 77% and 43%, respectively. PFS and hPFS were 7.6 and 11.2 months, respectively.. M-PHP using the GEN 2 filter can achieve a high ORR and prolonged survival in patients with liver-only ocular melanoma metastases.

To investigate the safety and toxicity of percutaneous hepatic perfusion with melphalan (M-PHP) with the Delcath Systems' second-generation (GEN 2) filter and compare the outcomes with historical data from studies using the first-generation filter.. A prospective, single-arm, single-center phase II study was carried out including 35 patients with unresectable, histologically confirmed liver metastases from ocular melanoma between February 2014 and June 2017. Main exclusion criteria were extrahepatic disease and age > 75 years. M-PHP was performed with melphalan 3 mg/kg (maximum dose 220 mg). Safety and toxicity were assessed according to the Common Terminology Criteria for Adverse Events version 4.03.. A total of 67 M-PHPs were performed in 35 patients (median 2 procedures). Although hematologic grade 3/4 events were seen in the majority of patients (thrombocytopenia 54.5%, leukopenia 75.6%, neutropenia 66.7%, anemia (only grade 3) 18.1%), these were all well manageable or self-limiting. Of the non-hematologic grade 3 events (n = 14), febrile neutropenia (n = 3), pulmonary emboli (n = 2) and post-procedural hemorrhage (n = 2) were most common. A case of sepsis with bacterial pharyngitis was the only non-hematologic grade 4 event. Prior therapy for liver metastases was found to be a predictor of late grade 3/4 neutropenia with an odds ratio of 5.5 (95% CI 1.4-21.7).. M-PHP using the GEN 2 filter has an acceptable safety and toxicity profile, and seems to reduce hematologic toxicity when compared to M-PHP with a first-generation filter. Prior therapy of liver metastases is a possible predictive factor in developing grade 3/4 hematologic toxicity.

Percutaneous hepatic perfusion (PHP) with melphalan is an effective treatment for patients with hepatic metastases, but associated with high rates of bone marrow depression. To reduce systemic toxicity, improvements have been made to the filtration system. In pre-clinical studies, the Delcath System's GEN2 filter was superior to the first-generation filters. In this clinical study, we analysed the pharmacokinetics and toxicity of PHP using the new GEN2 filter.. Starting February 2014, two prospective phase II studies were initiated in patients with hepatic metastases from ocular melanoma or colorectal cancer. In 10 PHP procedures performed in the first 7 enrolled patients, blood samples were obtained to determine filter efficiency and systemic drug exposure. PHP was performed with melphalan 3 mg/kg with a maximum of 220 mg. Complications were assessed according to CTCAE v4.03. Response was assessed according to RECIST 1.1.. Pharmacokinetic analysis of blood samples showed an overall filter efficiency of 86% (range 71.1-95.5%). The mean filter efficiency decreased from 95.4% 10 min after the start of melphalan infusion to 77.5% at the end of the procedure (p = 0.051). Bone marrow depression was seen after up to 80.0% of 10 procedures, but was self-limiting and mostly asymptomatic. No hypotension-related complications or procedure-related mortality occurred.. The GEN2 filter has a higher melphalan filter efficiency compared to the first-generation filters and a more consistent performance. PHP with the GEN2 filter appears to have an acceptable safety profile, but this needs further validation in larger studies.

Uveal melanoma is the most common primary intraocular malignancy in adults. Despite successful control of the primary tumor, metastatic disease will ultimately develop in approximately 35% of the patients, with the liver being the most common site for metastases. These metastases are generally refractory to systemic chemotherapy, and the median survival for patients with liver metastases is about 6 months. This phase II trial reports the experience of isolated hepatic perfusion (IHP) as a treatment option.. A total of 34 patients with isolated liver metastasis from ocular melanoma underwent IHP. An overall survival comparison was made using data retrieved from the National Patient Register managed by the Swedish National Board of Health and Welfare.. An overall radiological response was seen in 68% of the patients, with 12% having a complete response. Time to local progression was 7 months; 68% of the patients developed extrahepatic metastases after a median of 13 months, and the median overall survival was 24 months. There was a significant survival advantage of 14 months (p = 0.029) when comparing these patients with a control group consisting of the longest surviving patients in Sweden with uveal melanoma liver metastases not treated with IHP.. IHP is a treatment option with a high response rate and a potential survival benefit of more than 1 year. IHP should be considered an option in the treatment of uveal melanoma metastases. A randomized trial comparing IHP and best alternative care will start during 2013 (the SCANDIUM trial, ClinicalTrials.gov identifier NCT01785316).

Diffuse isolated liver metastases are the dominant mode of tumor progression in a number of cancers and present a major treatment challenge for oncologists. An experimental treatment, percutaneous hepatic perfusion (PHP), utilizes partial venovenous cardiopulmonary bypass to allow administration of high-dose chemotherapy directly and solely to the liver with filtration of chemotherapeutic agents from the blood prior to its return to the systemic circulation, thereby minimizing toxic systemic effects. The following case series describes the management of 5 patients with metastatic melanoma undergoing serial PHPs.. A single-center experience from a national multi-center random-assignment trial comparing PHP to best alternative care (BAC) in patients with diffuse melanoma liver metastases.. A tertiary care hospital.. Five patients with metastatic melanoma to the liver.. Five patients underwent a total of fifteen PHPs using a venovenous bypass circuit with hemofiltration, receiving hepatic intra-arterial melphalan, 3 mg/kg of ideal body weight, for 30 minutes with a total of 60 minutes of hemofiltration.. Five patients tolerated the procedure well with transient hemodynamic and metabolic changes.. In patients with diffuse isolated liver metastases, PHP is a safe and well-tolerated procedure that can be performed more than once and is associated with marked anti-tumor activity in some patients.

Chemosaturation with percutaneous hepatic perfusion (PHP; Hepatic CHEMOSAT(®) Delivery System; Delcath Systems Inc, USA) is a minimally invasive, repeatable regional therapy for unresectable hepatic metastases. It uses a system of catheters and filters to isolate hepatic venous blood from the systemic circulation, allowing delivery of high-dose chemotherapy to the hepatic artery. Effluent hepatic venous blood is filtered before being returned to the systemic circulation, thereby reducing exposure to chemotherapy. We describe our experiences with chemosaturation-PHP at 2 European centers.. 14 patients presented unresectable hepatic metastases from solid tumors; 13 received 1 - 3 sessions of chemosaturation-PHP. Melphalan 2.0 (n = 1) or 3.0 (n = 12) mg/kg was given as a 30-minute infusion into the hepatic artery. 12 patients were evaluable for tumor response.. One complete (cholangiocarcinoma, n = 1) and 6 partial responses (ocular, n = 3 or cutaneous melanoma, n = 3) were observed, 5 patients had stable disease (ocular melanoma, n = 3; breast cancer, n = 1; gastric cancer, n = 1). Mild to moderate filter-related toxicity (i. e. thrombocytopenia, anemia) was observed immediately post-procedure. Grade 3/4 melphalan-related pancytopenia developed after 1 - 2 weeks. All hematological events were managed effectively with transfusions and/or other supportive measures. The new high-efficiency filter showed milder toxicity and faster recovery. In one case, chemosaturation-PHP was abandoned prematurely due to heparin-induced vaginal bleeding, and one patient died due to retroperitoneal hemorrhage from heparin anti-coagulation.. Chemosaturation-PHP for non-resectable liver metastases is a feasible treatment option when performed by an experienced multi-disciplinary team. It may be a promising regional therapy for patients with no effective treatment options.

To improve isolated hepatic perfusion (IHP), we performed a phase I dose-escalation study to determine the optimal oxaliplatin dose in combination with a fixed melphalan dose.. Between June 2007 and July 2008, 11 patients, comprising of 8 colorectal cancer and 3 uveal melanoma patients and all with isolated liver metastases, were treated with a one hour IHP with escalating doses of oxaliplatin combined with 100 mg melphalan. Samples of blood and perfusate were taken during IHP treatment for pharmacokinetic analysis of both drugs and patients were monitored for toxicity, response and survival.. Dose limiting sinusoidal obstruction syndrome (SOS) occurred at 150 mg oxaliplatin. The areas under the concentration-time curves (AUC) of oxaliplatin at the maximal tolerated dose (MTD) of 100 mg oxaliplatin ranged from 11.9 mg/L h to 16.5 mg/L h. All 4 patients treated at the MTD showed progressive disease 3 months after IHP.. In view of similar and even higher doses of oxaliplatin applied in both systemic treatment and hepatic artery infusion (HAI), applying this dose in IHP is not expected to improve treatment results in patients with isolated hepatic metastases.

To compare the median overall survival of patients with isolated nonresectable liver metastases in comparable groups of patients treated with either isolated hepatic perfusion (IHP) with melphalan or systemic chemotherapy.. Colorectal cancer patients with isolated liver metastases, who underwent IHP, were included in this study. The control group consisted of a subgroup of colorectal cancer patients with liver metastases only, who were enrolled in the randomized CApecitabine, IRinotecan, Oxaliplatin (CAIRO) phase III study.. Ninety-nine patients were treated with IHP, and 111 patients were included in the control group. All patient characteristics were comparable except for age. Median follow-up was 78.1 months for IHP versus 54.7 months in the control group. Median overall survival was 25.0 [95% confidence interval (CI) 19.4-30.6] months for IHP and 21.7 (95% CI 19.6-23.8) months for systemic treatment and did not differ significantly (P = 0.29). Treatment-related mortality was 2% for the systemic treatment and 6% for IHP (P = 0.11).. Compared with a patient group with comparable characteristics treated with systemic chemotherapy, IHP does not provide a benefit in overall survival in patients with isolated nonresectable colorectal liver metastases. Currently, the use of IHP cannot be advocated outside the scope of clinical studies.

The liver is one of the most common sites for metastatic solid tumors. If the liver is the only site of metastatic disease, regional treatment options can offer the benefit of high local exposure with limited systemic toxicity, especially for patients without (further) systemic treatment options. We report the results of our experience with isolated hepatic perfusion (IHP) in patients with isolated liver metastases from a variety of primary tumors.. Nineteen patients with isolated unresectable liver metastases from a variety of tumors (13 uveal melanomas, 2 neuroendocrine carcinomas, 2 gastrointestinal stromal tumors, 1 hepatocellular carcinoma, and 1 high-grade sarcoma) were treated with a 60-min IHP using 200 mg melphalan. Patients were monitored for toxicity, response according to response evaluation criteria in solid tumors (RECIST) criteria, and survival.. One melanoma patient was not perfused due to insufficient isolation of the liver. There was no treatment-related mortality. Reversible grade 3 or 4 hepatoxicity occurred in 10 (56%) patients, while veno-occlusive disease occurred in 4 (22%) patients. Of the 12 uveal melanoma patients who were perfused, 4 (33%) patients had a partial hepatic response, 6 (50%) patients had stable hepatic disease, and 2 (17%) patients were immediately progressive. Median disease-free survival was 6.6 months with a median overall survival of 10.0 months. Fifty percent of other primary tumors showed at least partial remission, including one complete remission in a high-grade sarcoma patient.. IHP with melphalan shows activity in patients with liver metastases from a variety of primary tumors, but other or additional drugs may improve therapeutic outcome.

We conducted a phase I study of a 30-minute hepatic artery infusion of melphalan via a percutaneously placed catheter and hepatic venous hemofiltration using a double balloon catheter positioned in the retrohepatic inferior vena cava to shunt hepatic venous effluent through an activated charcoal filter and then to the systemic circulation. The purpose of the study was to demonstrate feasibility in an initial cohort and subsequently determine the maximum tolerated dose and dose-limiting toxicity of melphalan.. The initial cohort (n = 12) was treated with 2.0 mg/kg of melphalan before dose escalation to 3.5 mg/kg (n = 16). Total hepatic drug delivery, systemic levels, and percent filter efficiency were determined. Patients were assessed for hepatic and systemic toxicity and response.. A total of 74 treatments were administered to 28 patients. Twelve patients with primary and metastatic hepatic tumors received 30 treatments (mean, 2.5 per patient) at an initial melphalan dose of 2.0 mg/kg. At 3.5 mg/kg, a dose-limiting toxicity (neutropenia and/or thrombocytopenia) was observed in two of six patients. Transient grade 3/4 hepatic and systemic toxicity was seen after 19% and 66% of treatments, respectively. An overall radiographic response rate of 30% was observed in treated patients. In the 10 patients with ocular melanoma, a 50% overall response rate was observed, including two complete responses.. Delivery of melphalan via this system is feasible, with limited, manageable toxicity and evidence of substantial antitumor activity; 3 mg/kg is the maximum safe tolerated dose of melphalan administered via this technique.

Uveal melanoma is the most common primary intraocular tumour in adults. After treatment of the primary tumour, up to 50% of patients will ultimately develop metastases. Treatment options for metastases are limited. When uveal melanoma metastases are confined to the liver, isolated hepatic perfusion (IHP) could be a treatment option. Herein, we report the results of a small group of patients with uveal melanoma metastases of the liver treated with IHP. Eight patients with uveal melanoma metastases confined to the liver underwent IHP with high-dose melphalan (200 mg) for 1 h. Toxicity was graded according to the National Cancer Institute Common Toxicity Criteria and tumour response was assessed according to World Health Organization criteria. The tumour response rate (complete or partial remission) was 50%. The median time to progression was 6.7 months (range, 1.7-16.9 months). The overall median survival was 9.9 months (range, 4.7-34.6 months), with a 1 year survival of 50% and a 2 year survival of 37.5%. Three patients experienced grade 3-4 hepatotoxicity which was transient within 3 months. Although only a small group of patients has been treated and evaluated so far, IHP is a treatment option for uveal melanoma metastases confined to the liver which can result in tumour responses and may lead to survival benefits in a selective group of patients.

Isolated hepatic perfusion for irresectable metastases confined to the liver has reported response rates of 50% to 75%. Magnitude, costs, and nonrepeatability of the procedure are its major drawbacks. We developed a less invasive, less costly, and potentially repeatable balloon catheter-mediated isolated hypoxic hepatic perfusion (IHHP) technique.. In this phase I and II study, 18 consecutive patients with irresectable colorectal or ocular melanoma hepatic metastases were included. Two different perfusion methods were used, both with inflow via the hepatic artery, using melphalan 1 mg/kg. In the first eight patients, the portal vein was occluded, and outflow was via the hepatic veins into an intracaval double-balloon catheter. This orthograde IHHP had on average 56% leakage. In next 10 patients, we performed a retrograde outflow IHHP with a triple balloon blocking outflow into the caval vein and allowing outflow via the portal vein. The retrograde IHHP still had 35% leakage on average.. Although local drug concentrations were high with retrograde IHHP, systemic toxicity was still moderate to severe. Partial responses were seen in 12% and stable disease in 81% of patients. The median time to local progression was 4.8 months.. We have abandoned occlusion balloon methodology for IHHP because it failed to obtain leakage control. We are presently conducting a study using a simplified surgical retrograde IHHP method, in which leakage is fully controlled, which translates into high response rates.

We report results of using isolated hepatic perfusion (IHP) in patients with advanced progressive liver metastases (LM) from pancreatic and gastrointestinal neuroendocrine neoplasms (NENs).. Thirteen patients with LM from NENs (mean percent hepatic replacement, 30; range, 10-60) were treated with a 1-hour hyperthermic IHP via a laparotomy with the use of 1.5 or 2.0 mg/kg melphalan and/or 1 mg tumor necrosis factor. An oxygenated extracorporeal circuit with inflow through the gastroduodenal artery and common hepatic artery, and outflow to a segment of the inferior vena cava was used. Portal flow and inferior vena cava flow were shunted to the axillary vein. Radiographic response, recurrence pattern, and survival were assessed.. Mean operative time was 9 hours (8-11 hours), and a median hospital stay was 10 days (6-64 days). Fifty percent of evaluable patients had a radiographic partial response in the liver (mean duration, 15 months; range, 6-26 months; 2 ongoing). Four had a marginal response (25%-49% reduction in the neoplasm). The median, hepatic, progression-free survival was 7 months (range, 3-27 months). The median actuarial survival was 48 months including 1 treatment mortality (median follow-up, 23 months).. For patients with advanced LM from NENs, IHP provides a reasonable response rate and duration with acceptable morbidity; continued clinical evaluation is important.

Isolated hepatic perfusion (IHP) involves complete vascular isolation of the liver to allow treatment with doses that would be toxic if delivered systemically. A phase II study of IHP in patients with colorectal metastases confined to the liver was performed.. Seventy-three patients with irresectable colorectal metastases underwent IHP with high-dose melphalan (200 mg) for 1 h. Toxicity was graded according to the National Cancer Institute Common Toxicity Criteria and tumour response was assessed according to World Health Organization criteria.. Seventy-one patients were perfused according to the protocol. Four patients died within 30 days after IHP, resulting in an operative mortality rate of 5.6 per cent. Sixteen patients (22.5 per cent) experienced grade 3-4 hepatotoxicity 1 week after IHP, which was transient and resolved within 3 months in all patients. The tumour response rate (complete or partial remission) was 59 per cent. Median time to progression was 7.7 (range 2.3-31.4) months. Overall median survival after IHP was 28.8 months with a 3-year survival rate of 37 per cent.. IHP for irresectable colorectal metastases confined to the liver resulted in good response rates and long-term survival in a selected group of patients.

Liver metastases are the sole or life-limiting component of disease in the majority of patients with ocular melanoma who recur. Because median survival after diagnosis of liver metastases is short and no satisfactory treatment options exist, we have conducted clinical trials evaluating isolated hepatic perfusion (IHP) for patients afflicted with this condition.. Twenty-nine patients (male: 14, female: 15; mean age, 49 years) with unresectable liver metastases from ocular melanoma were treated with a 60-min hyperthermic IHP using 1.5 mg/kg of melphalan (mean total dose 105 mg). Via laparotomy, perfusion inflow was established with a cannula in the gastroduodenal artery and outflow via a cannula positioned in an isolated segment of the retrohepatic inferior vena cava. Portal and infra-renal inferior vena cava blood flow was shunted externally to the axillary vein using a veno-veno bypass circuit. Patients were assessed for toxicity, radiographic response, and survival.. There was no treatment related mortality and transient grade 3/4 hepatic toxicity was observed in 19 patients (65%). Mean length of operation and hospital stay was 8.3 h and 10 days, respectively. There were 3 (10%) complete responses (duration: 12, 14+, 15 months) and 15 partial responses (52%; mean duration: 10 months). The initial site of disease progression included liver in 17 of 25 patients (68%) who recurred. At a median follow-up of 30.7 months the median actuarial progression-free and overall survivals were 8 and 12.1 months, respectively.. IHP with melphalan alone results in significant regression of established liver metastases for patients with ocular melanoma. However, after IHP, disease progression is most commonly observed in the liver, and survival after disease progression is short. On the basis of a pattern of tumor progression predominantly in liver, continued clinical evaluation of hepatic directed therapy in this patient population is justified.

Unresectable colorectal liver metastases are a significant clinical problem. Isolated hepatic perfusion (IHP) is a regional treatment technique that delivers high dose chemotherapy, biologic agents, and hyperthermia via a completely isolated vascular recirculating perfusion circuit as a means of regionally treating liver tumors. This study presents our results of IHP with tumor necrosis factor (TNF) plus melphalan or IHP with melphalan alone followed by infusional floxuridine (FUDR) and leucovorin in patients with advanced or refractory unresectable hepatic colorectal metastases.. Fifty-one patients with unresectable colorectal hepatic metastases underwent a 60-minute IHP with 1.5 mg/kg melphalan and hyperthermia (39 degrees C to 40 degrees C). Thirty-two patients received IHP with 1 mg TNF with melphalan and 19 patients had IHP with melphalan alone followed by monthly hepatic intra-arterial infusional (HAI) FUDR (0.2 mg/kg/day) and leucovorin (15 mg/M(2)/day) for 14 days monthly for up to 12 months. Twenty-six patients failed 1 or more previous treatment regimens for established hepatic metastases and 27 had greater than 25% hepatic replacement (PHR) by tumor. Patients were monitored for response, toxicity, and survival.. There was 1 perioperative death (2%), and only 2 patients (4%) had measurable perfusate leak during IHP (both less than 4%). In the 32 patients treated with IHP alone there were no detectable systemic TNF or melphalan levels during perfusion. The overall objective radiographic response rate (all partial [PR]) was 76% (38 of 50 assessable patients) with a median duration of 10.5 months (range, 2 to 21 months). Twenty-four of 31 patients (77%) had a PR after IHP alone and 14 of 19 (74%) after IHP with postperfusion HAI. Median duration of response was 8.5 months after IHP alone and 14.5 months after IHP and HAI; median survival was 16 and 27 months, respectively. There were 18 PRs in 26 patients (69%) whose prior therapy had failed and 18 PRs in 27 patients (67%) with PHR of 25 or greater.. IHP can be performed with acceptably low morbidity and has significant antitumor activity in patients with unresectable hepatic metastases from colorectal cancer including those with refractory disease or PHR of 25 or greater. HAI appears to prolong the duration of response after IHP, and this combined treatment strategy deserves additional clinical evaluation as a therapeutic modality in this setting.

A phase I dose-escalation study was performed to determine whether isolated hepatic perfusion (IHP) with melphalan (L-PAM) allows exposure of the liver to much higher drug concentrations than clinically achievable after systemic administration and leads to higher tumour concentrations of L-PAM. Twenty-four patients with colorectal cancer confined to the liver were treated with L-PAM dosages escalating from 0.5 to 4.0 mg kg(-1). During all IHP procedures, leakage of perfusate was monitored. Duration of IHP was aimed at 60 min, but was shortened in eight cases as a result of leakage from the isolated circuit. From these, three patients developed WHO grade 3-4 leukopenia and two patients died due to sepsis. A reversible elevation of liver enzymes and bilirubin was seen in the majority of patients. Only one patient was treated with 4.0 mg kg(-1) L-PAM, who died 8 days after IHP as a result of multiple-organ failure. A statistically significant correlation was found between the dose of L-PAM, peak L-PAM concentrations in perfusate (R = 0.86, P< or =0.001), perfusate area under the concentration-time curve (AUC; R = 0.82, P<0.001), tumour tissue concentrations of L-PAM (R = 0.83, P = 0.011) and patient survival (R = 0.52, P = 0.02). The peak L-PAM concentration and AUC of L-PAM in perfusate at dose level 3.0 mg kg(-1) (n = 5) were respectively 35- and 13-fold higher than in the systemic circulation, and respectively 30- and 5-fold higher than reported for high dose oral L-PAM (80-157 mg m(-2)) and autologous bone marrow transplantation. Median survival after IHP (n = 21) was 19 months and the overall response rate was 29% (17 assessable patients; one complete and four partial remissions). Thus, the maximally tolerated dose of L-PAM delivered via IHP is approximately 3.0 mg kg(-1), leading to high L-PAM concentrations at the target side. Because of the complexity of this treatment modality, IHP has at present no place in routine clinical practice.

There are no satisfactory treatment options for patients with ocular melanoma metastatic to liver, and after liver metastases are identified, median survival is only between 2 and 7 months. Because liver metastases are the sole or life-limiting component of disease in the vast majority of patients who recur, we reasoned that complete vascular isolation and perfusion of the liver might result in clinically meaningful regression of disease. Between September 1994 and July 1999, 22 patients (13 women and 9 men; mean age, 49 years) with ocular melanoma metastatic to liver were treated with a 60-min hyperthermic isolated hepatic perfusion (IHP) using melphalan alone (1.5-2.5 mg/kg, n = 11) or with tumor necrosis factor (TNF, 1.0 mg, n = 11). Via a laparotomy, IHP inflow was via the hepatic artery alone (n = 17) or hepatic artery and portal vein (n = 5) and outflow from an isolated segment of inferior vena cava. Most patients had advanced tumor burden with a mean percentage of hepatic replacement of 25% (range, 10-75%) and a median number of metastatic nodules of 25 (range, 5 to >50). Complete vascular isolation was confirmed in all patients using a continuous intraoperative leak monitoring technique with 131I radiolabeled albumin. There was one treatment mortality (5%). The overall response rate in 21 patients was 62% including 2 radiographic complete responses (9.5%) and 11 partial responses (52%). The overall median duration of response was 9 months (range, 5-50) and was significantly longer in those treated with TNF than without (14 versus 6 months, respectively; P = 0.04). Overall median survival in 22 patients was 11 months. These data indicate that a single 60-min IHP can result in significant regression of advanced hepatic metastases from ocular melanoma. TNF appears to significantly prolong the duration of response.

For a variety of histologies, the liver represents the only or the dominant site of metastatic disease. Regional treatment of the liver has the theoretic advantage of maximizing drug delivery while minimizing systemic toxicity. This article describes the technique of isolated hepatic perfusion using tumor necrosis factor and melphalan under conditions of moderate hyperthermia for the treatment of unresectable liver tumors.. Fifty patients with biopsy-proved unresectable primary or metastatic cancer to the liver were treated. Isolated hepatic perfusion was performed for 60 minutes under conditions of moderate hyperthermia during a laparotomy with inflow through the gastroduodenal artery and outflow through an isolated segment of inferior vena cava. During isolated hepatic perfusion portal and infrahepatic blood flow were shunted externally by a centrifugal pump to the axillary vein. Complete vascular isolation was confirmed intraoperatively using a continuous 131I-labeled serum albumin leak monitoring system. Operative and perfusion parameters were recorded.. By using a standard operative technique to achieve complete vascular isolation of the liver during perfusion, there was no leak ofperfusate detected in 48 of 50 patients as determined by the continuous leak monitoring system and absence of detectable systemic tumor necrosis factor levels. Operating time, transfusion requirements, and blood loss were within the range expected for a major operative procedure. Stable hemodynamic and perfusion parameters were achieved consistently and all patients successfully completed the 60-minute perfusion. Two patients (4%) died as a result of treatment and significant tumor regression was observed in 75%.. Isolated hepatic perfusion is a technique that can be used to deliver high doses of chemotherapy or biologic therapy regionally and without systemic exposure. By using a standard operative technique, continuous intraoperative leak monitoring, and an external veno-veno bypass circuit, this procedure can be done safely and with acceptable morbidity and mortality. This article demonstrates that sustained and complete vascular isolation of the liver can be achieved and indicates further study is warranted to better define the role of isolated hepatic perfusion in the treatment of unresectable liver tumors.

Despite reports that i.v. melphalan is active in the settings of conditioning regimens utilizing high-dose chemotherapy for autologous bone marrow transplantation and in isolated limb perfusion for the treatment of malignant melanoma, its activity at conventional doses has never been defined in this disease. We conducted a phase II study of conventional-dose i.v. melphalan (30 mg/m2) in 17 patients with metastatic melanoma. All patients were previously untreated with chemotherapy with performance status 0, 1 or 2. Forty-seven cycles were given with a median of two cycles. One patient was not evaluable due to early death. There were no responses in the 16 patients, resulting in a 0% response rate (95% confidence interval = 0-17%). We conclude that conventional-dose melphalan by i.v. administration has no appreciable activity in patients with metastatic malignant melanoma.

To determine the toxicity and efficacy of isolated hepatic perfusion with tumour necrosis factor alpha (TNF-alpha) and melphalan (Alkeran) under mild hyperthermic conditions.. A phase I trial was performed. Eleven patients with unresectable metastatic malignancies in the liver were pre-treated with 3 x 10(6) U leukocyte IFN daily 2 days before the perfusion. The liver was isolated and inflow catheters inserted in the hepatic artery and the portal vein. The hepatic veins were drained via a catheter in the retrohepatic caval vein. The venous blood flow from the lower extremities and the splanchnic circulation was bypassed to the axillar vein. The liver circuit was perfused with oxygenated blood and 30-200 microg TNF-alpha was added. At 39 degrees C in the liver circuit 0.5 mg/kg melphalan was added and the perfusion was continued for 1 h.. Six patients underwent re-operation due to post-operative bleeding. Two patients died of coagulopathy or multiple organ failure within the first post-operative month. Three of six patients with liver metastases from malignant melanoma or leiomyosarcoma showed a partial response while no patients with liver metastases from colorectal cancer showed any response. The mean survival time was 20 months, which is within the same range as seen in previous isolated hepatic perfusion (IHP) studies.. IHP with this drug regimen is a method with a considerable toxicity, though it is hard to distinguish between toxicity from TNF-alpha and that from the perfusion procedure itself. The method was not effective in patients with colorectal liver metastasis, but the results in melanoma and leiomyosarcoma patients warrant further studies.

In this study, we have evaluated hepatotoxicity, secondary cytokine production and hepatic acute-phase response (APR) in patients who underwent isolated hepatic perfusion (IHP) with tumour necrosis factor (TNF) alpha and melphalan for irresectable colorectal liver metastases.. An extracorporeal veno-venous bypass was used to shunt blood from the lower body and intestines to the heart. Inflow catheters were placed in the hepatic artery and portal vein, and an outflow catheter in the inferior caval vein. The liver was perfused for 60 min with 0.4 mg of TNF-alpha plus 1 mg kg-1 melphalan (IHPTM group, n = 6) or 1 mg kg-1 melphalan (IHPM group, n = 3). The liver was washed with macrodex before restoring vascular continuity.. After the washout procedure, a TNF-alpha peak (169 +/- 38 pg mL-1) was demonstrated in the IHPTM group only. Both groups demonstrated peak levels of interleukin 6 (IL-6) in the perfusate as well as systemically. These were significantly higher in the IHPTM group. Acute-phase protein (APP) levels followed a similar pattern as has been demonstrated after major surgery, with no significant differences between both groups. The addition of TNF-alpha to the perfusate did not lead to a significant difference in APP levels and the time course between groups.. IHP with TNF and melphalan is followed by a transient systemic peak of TNF directly after liver washout. Secondary IL-6 induction was seen in the present study after IHP with and without TNF, which was highest when TNF was added. This phenomenon cannot be extrapolated to APP induction, which appeared unaffected by the addition of TNF, presumably because the surgical procedure itself already causes maximal stimulation of APP production.

To evaluate the efficacy and systemic and regional toxicities of hyperthermic isolated hepatic perfusion (IHP) using tumor necrosis factor (TNF) and melphalan for the treatment of unresectable primary or metastatic cancers confined to the liver.. Thirty-four patients (18 men and 16 women; mean age, 49 years) underwent a 60-minute hyperthermic (39.5 degrees to 40.0 degrees C) IHP performed by laparotomy that used TNF 1.0 mg and melphalan 1.5 mg/kg. Perfusion inflow was through the gastroduodenal artery and outflow was from a cannula positioned in an isolated segment of retrohepatic inferior vena cava (IVC). Infrahepatic IVC and portal venous blood flow were shunted to the axillary vein using an external venoveno bypass circuit. Complete vascular isolation of the liver was confirmed by an I-131-labelled human serum albumin monitoring technique.. There was no operative mortality. Seventy-five percent of patients had reversible grade III or IV (National Cancer Institute Common Toxicity Criteria) hepatic toxicity with one treatment-related mortality (3%) because of hepatic venoocclusive disease. In 33 assessable patients, the overall response rate was 75% (complete response, one patient [3%]; partial response, 26 patients [72%]). With a median potential follow-up of 15 months, the mean duration of response was 9 months (range, 2 to 30 months).. IHP with TNF and melphalan results in significant regression of bulky hepatic cancers confined to the liver in the majority of patients. Based on these initial results, further refinement of this treatment technique is warranted; perhaps by the combination of IHP with other regional treatment strategies to provide long-term control of unresectable cancers confined to liver.

We report our experience with isolated hepatic perfusion (IHP) with tumor necrosis factor (TNF) and melphalan in an experimental pig study and of a phase I study in humans. IHP was performed with inflow catheters in the hepatic artery and portal vein and an outflow catheter in eh caval vein. An extracorporeal venovenous bypass was used. IHP consisted of a 60-min perfusion with hyperthermia (> 41 degrees C). For the pig protocol rhTNF alpha 50 micrograms/kg alone (n = 5) or rhTNF alpha 50 micrograms/kg plus melphalan 1 mg/kg (n = 3) were added. In two control pigs no drugs were added. In the phase I study, patients received melphalan 1 mg/kg with 0.4 mg rhTNF alpha (n = 8) or 0.8 mg rhTNF alpha (n = 1). After the perfusion the liver was washed with Macrodex before vascular continuity was restored. All pigs but one survived the procedure. Systemic leakage was less than 0.02%. Transient, mild liver toxicity was seen in all pigs, including controls, as demonstrated by liver enzyme assays and histology. There was no significant hemodynamic, cardiopulmonary hematological, or renal toxicity. In the phase I clinical study there was leakage in one patient (cumulative leakage 20%). There were three perioperative deaths (one possibly drug-related). All patients demonstrated significant hepatotoxicity. Survival ranged from 6 to 26 months (median 10.3 months). All patients demonstrated a tumor response (partial response 5/6, 1/6 stable disease) with a median duration of 18 weeks. In contrast to our pig program, many problems were encountered in the phase I study. By using both the hepatic artery and portal vein for IHP we encountered more toxicity than expected based on data from the pig program, resulting in fatal coagulative disturbances in one patient who received the second rhTNF alpha dose. Furthermore, local control after one IHP with TNF alpha and melphalan is only temporary.

A phase I trial was performed to determine the toxicity and efficacy of isolated hepatic perfusion with tumour necrosis factor alpha (TNF) and melphalan (Alkeran) under mild hyperthermic conditions. Eleven patients with unresectable metastatic malignancies in the liver (malignant melanoma, leiomyosarcoma, colorectal cancer) underwent the procedure. Compared to our earlier experience with melphalan and cis-platinum under hyperthermic conditions (41.7 degrees C), this phase I study with TNF 30-200 micrograms and melphalan ).5 mg/kg body weight under 39 degrees C hyperthermia neither improved the response rate nor decreased the serious adverse effects. Two patients died within the first postoperative month owing to coagulopathy or multiple organ failure. Five patients were reoperated owing to postoperative bleeding. Three of six patients with liver metastases from malignant melanoma or leiomyosarcoma and none of five patients with liver metastases from colorectal cancer showed a partial response.

Tumor cell resistance against melphalan (LPAM) has been associated with increased cellular reduced glutathione (GSH) levels and glutathione S-transferase activity. Therefore, GSH conjugation of LPAM has been hypothesized to be a key factor in tumor cell resistance. In the present study, we evaluated GSH conjugation of LPAM by the perfused liver in patients with colorectal cancer metastases undergoing a Phase II study of isolated liver perfusion as well as in the rat. To evaluate whether LPAM-GSH conjugates were synthesized in the rat in vivo, LPAM was infused i.v. at a rate of 2.0 micromol/kg/min. In bile samples obtained during the infusion, two major GSH conjugates were identified by mass spectrometry: mono-hydroxy-mono-GSH-LPAM and di-GSH-LPAM. The maximum biliary excretion rate of these two conjugates accounted for only 1.3% of the LPAM infusion rate. In bile or perfusate samples from patients treated for 60 min initially with 0.3 mM LPAM in the perfusion medium via isolated liver perfusion (200 mg LPAM in approximately 2 liters perfusion medium), none of the above-mentioned conjugates were detected. When comparable rat liver perfusions were performed initially with 66 microM or 0.66 mM LPAM in the perfusion medium, bile samples did contain GSH-LPAM conjugates; the cumulative biliary excretion of the two conjugates amounted to 0.4 and 0.2% of the LPAM dose, respectively. These data suggest that both in rats and humans, hepatic GSH conjugation plays a very minor (if any) role in the elimination of LPAM and, therefore, that modulation of GSH levels is unlikely to affect the rate of elimination of this drug.

Current treatments for metastatic breast cancer are not associated with significant survival benefits despite response rates of over 50%. High-dose therapy with autologous bone marrow transplantation (ABMT) has been investigated, particularly in North America, and prolonged survival in up to 25% of women has been reported, but with a significant treatment-related mortality. However, in patients with haematological malignancies undergoing autologous transplantation, haematopoietic reconstruction is significantly quicker and mortality lower than with ABMT, when peripheral blood progenitor cells (PBPCs) are used. In 32 women with metastatic breast cancer, we investigated the feasibility of PBPC mobilisation with high-dose cyclophosphamide and granulocyte colony-stimulating factor (G-CSF) after 12 weeks' infusional induction chemotherapy and the subsequent efficacy of the haematopoietic reconstitution after conditioning with melphalan and either etoposide or thiotepa. PBPC mobilisation was successful in 28/32 (88%) patients, and there was a rapid post-transplantation haematopoietic recovery: median time to neutrophils > 0.5 x 10(9) l-1 was 14 days and to platelets > 20 x 10(9) l-1 was 10 days. There was no procedure-related mortality, and the major morbidity was mucositis (WHO grade 3-4) in 18/32 patients (56%). In a patient group of which the majority had very poor prognostic features, the median survival from start of induction chemotherapy was 15 months. Thus, PBPC mobilisation and support of high-dose chemotherapy is feasible after infusional induction chemotherapy for patients with metastatic breast cancer, although the optimum drug combination has not yet been determined.

In an open study of unresectable liver tumours, isolated regional perfusion with hyperthermia and cytotoxic drugs has been tested in 29 patients. Four patients had primary hepatocellular cancer, 10 patients had metastases from malignant melanoma, remaining from breast cancer, colorectal cancer, midgut carcinoids and miscellaneous primaries. At laparotomy the proper hepatic artery and portal vein were canulated and connected to a pump oxygenator. The inferior vena cava was canulated with a triple lumen catheter (Perfufix) allowing for porto-caval shunting, drainage of lower body and renal veins to the heart and separate drainage of liver veins to the pump oxygenator. Liver perfusion was performed with a mean flow of 900 ml per min. Melphalan and cis-platinum 0.5 mg/kg body-weight were added to the perfusate for 1 h after liver temperature reached 40 degrees C. Four patients died within 30 days of perfusion due to multiple organ failure. These patients had more than 50% of liver volume occupied by cancer. All surviving patients developed reversible hepato- and renal toxicity. Partial tumour regression was registered in 20% of the patients. Five patients have survived more than three years. Hyperthermic liver perfusion is feasible but in patients with massive liver tumour, there is a significant risk of developing multiple organ failure.

The therapeutic effects of adriamycin and of melphalan in patients with advanced carcinoma of the ovary were tested in a prospective randomized study. Complete and partial remission occurred in eight of 19 patients treated with adriamycin and in four of 20 patients given melphalan. The difference, however, is not statistically significant. The median duration of complete and partial remissions was slightly longer after treatment with melphalan than with adriamycin. The number of cycles required to produce the initial regression state was less in the patients in the group given adriamycin as compared with those in the group treated with melphalan. No cross resistance was observed between the two drugs. These data indicate that, in patients with carcinoma of the ovary, the therapeutic efficacy of adriamycin is competitive with that of the most effective conventional agents, such as melphalan.

Cholangiocarcinoma (CCA) are the second most common primary liver tumors and carry a dismal prognosis. Chemosaturation with percutaneous hepatic perfusion (PHP) is a palliative, intra-arterial therapeutic approach that provides a high dose chemotherapy of the liver with reduced systemic exposure. Aim of this retrospective, monocentric study was to analyze PHP as a palliative treatment for unresectable CCA. Toxicity, adverse events and complications were classified using the Common Terminology Criteria for Adverse Events (CTCAE v5.0). Overall response rate (ORR) and disease control rate (DCR) were evaluated according to the Response Evaluation Criteria in Solid Tumors (RECIST1.1). Median overall survival (mOS), median progression-free survival (mPFS) and hepatic mPFS (mhPFS) were computed using Kaplan-Meier estimation. In total 17 patients were treated with 42 PHP between 10/2014 and 09/2020. No significant complications occurred during the interventions. mOS was 27.6 (interquartile range (IQR) 16.5-37) months from first diagnosis and 9.9 (IQR 3.8-21) months from first PHP. mPFS was 4 (IQR 2-7) and mhPFS was 4 (IQR 3-10) months. ORR was 25% and DCR 75%. Significant, but transient hematotoxicity was frequent with grade 3/4 thrombopenia after 50%, leukopenia after 26% and anaemia after 21% of the interventions. An increase of transaminases (AST increase after 21% and ALT increase after 14% of the PHP) developed more often than a deterioration of the liver synthesis capacity. Salvage treatment with PHP has the potential to prolong life in selected patients with unresectable, refractory cholangiocarcinoma. The interventional procedure is safe. Post-interventional toxicity is frequent but manageable.

Uveal melanoma accounts for 80% of all ocular melanomas, and 30-60% of patients have metastases to the liver. A few patients are candidates for liver resection, and this disease is associated with poor prognosis. There are few data on optimal management of metastatic uveal melanoma. Isolated hepatic perfusion is a perspective method for regional treatment of inoperable metastatic liver lesions with uveal melanoma. We present a patient with uveal melanoma who underwent previous enucleation of the eye. Cancer progressed 15 years later as an isolated inoperable metastatic liver lesion. The patient underwent isolated liver perfusion with melphalan, hyperthermia and oxygenation. Subsequently, the patient received systemic therapy with pembrolizumab. Partial response was achieved 1 month after the procedure. There was no progression for 20 months after surgery under systemic therapy with pembrolizumab. Thus, isolated liver chemoperfusion with melphalan is advisable in these patients.. Увеальная меланома составляет 80% всех глазных меланом, и 30—60% пациентов имеют метастазы, ограниченные только печенью. Немногие пациенты являются кандидатами на потенциально лечебную резекцию печени, поэтому это заболевание связано с плохим прогнозом. Опубликовано мало данных об оптимальном ведении и лечении метастатической увеальной меланомы. Перспективным методом регионального лечения неоперабельного метастатического поражения печени увеальной меланомой является метод изолированной химиоперфузии печени. Мультидисциплинарный коллектив НМИЦ радиологии и Костромского онкологического диспансера представил клинический случай больной с увеальной меланомой, перенесшей энуклеацию глаза, и прогрессированием спустя 15 лет в форме изолированного нерезектабельного метастатического поражения печени. Пациентке была проведена изолированная перфузия печени с мелфаланом, гипертермией и оксигенацией. В дальнейшем пациентке проводили системную терапию пембролизумабом. Достигнут частичный ответ через 1 мес после выполнения процедуры. Констатировано отсутствие прогрессирования на протяжении 20 мес после операции на фоне системной терапии пембролизумабом. На основании представленного клинического наблюдения этой категории пациентов целесообразно применение изолированной химиоперфузии печени мелфаланом в комбинации с иммунотерапией.

Chemosaturation (CS; CHEMOSAT®, Delcath Systems Inc.) temporarily administers melphalan into the liver by percutaneous hepatic perfusion (PHP). CS-PHP can effectively control growth in liver tumors, but efficacy and tolerability of sequential treatments are unclear. We analyzed outcomes of sequential CS-PHP treatment. Patients with either unresectable intrahepatic metastases of ocular melanoma (OM, n = 9), cholangiocarcinoma (CCA, n = 3), or hepatocellular carcinoma (HCC, n = 1) were recruited retrospectively. Response was assessed by tomography imaging. Ten patients (mean age 60 years) with more than one CS-PHP treatment were included. CS-PHP was administered 2-6 times in the OM patients, 3 times in the CCA, and the HCC patient received 6 treatments. Overall response rate (ORR) to CS-PHP was 80%, and stable disease was achieved in one patient. Median hepatic progression-free survival (hPFS) was 336 days (range 0-354) for OM, 251 days for the CCA patient, and 256 days for the HCC patient. At the end of observation (153-701 days after first CS-PHP), 6/10 patients were still alive (5/9 with OM, 0 with CCA, and 1 with HCC). Death cases were not related to CS-PHP. Adverse events were mostly hematologic, grade I-IV, and self-resolving. The liver function was not deteriorated by CS-PHP. We conclude that repeated CS-PHP treatments were effective and well tolerated in the long term.

Percutaneous hepatic perfusion with melphalan (M-PHP) is increasingly used in patients with liver metastases from various primary tumors, yet data on colorectal liver metastases (CRLM) are limited. The aim of this study was to prospectively evaluate the efficacy and safety of M-PHP in patients with CRLM.. Prospective, single-center, single-arm phase II study of M-PHP with hemofiltration in patients with unresectable CRLM. Proven, extrahepatic metastatic disease was one of the exclusion criteria. Primary outcomes were overall response rate (ORR) and best overall response (BOR). Secondary outcomes were overall survival (OS), progression-free survival (PFS), hepatic PFS (hPFS), and safety.. A total of 14 M-PHP procedures were performed in eight patients between March 2014 and December 2015. All patients (median age 56 years, ranging from 46 to 68) had received (extensive) systemic chemotherapy before entering the study. The ORR was 25.0%, with two out of eight patients showing partial response as BOR. Median OS was 17.3 months (ranging from 2.6 to 30.9) with a one-year OS of 50.0%. Median PFS and hPFS were 4.4 and 4.5 months, respectively. No serious adverse events occurred. Grade 3/4 hematologic adverse events were observed in the majority of patients, though all were transient and well-manageable.. M-PHP is a safe procedure with only limited efficacy in patients with unresectable CRLM who already showed progression of disease after receiving one or more systemic treatment regimens.

Uveal melanoma, the most common primary ocular malignancy in adults, carries a poor prognosis: 50% of patients develop the metastatic disease with a 10-25% 1-year survival and no established standard of care treatment. Prior studies of melphalan percutaneous hepatic perfusion (M-PHP) have shown promise in metastatic uveal melanoma (mUM) patients with liver predominant disease but are limited by small sample sizes. We contribute our findings on the safety and efficacy of the procedure in the largest sample population to date. A retrospective analysis of outcome and safety data for all mUM patients receiving M-PHP was performed. Tumour response and treatment toxicity were evaluated using RECIST 1.1 and Common Terminology Criteria for Adverse Events v5.03, respectively. 250 M-PHP procedures were performed in 81 patients (median of three per patient). The analysis demonstrated a hepatic disease control rate of 88.9% (72/81), a hepatic response rate of 66.7% (54/81), and an overall response rate of 60.5% (49/81). After a median follow-up of 12.9 months, median overall progression-free (PFS) and median overall survival (OS) were 8.4 and 14.9 months, respectively. There were no fatal treatment-related adverse events (TRAE). Forty-three grade 3 (29) or 4 (14) TRAE occurred in 23 (27.7%) patients with a significant reduction in such events between procedures performed in 2016-2020 vs. 2012-2016 (0.17 vs. 0.90 per patient, P < 0.001). M-PHP provides excellent response rates and PFS compared with other available treatments, with decreasing side effect profile with experience. Combination therapy with systemic agents may be viable to further advance OS.

The aim of this study was to identify positive predictors for survival in uveal melanoma (UM) patients treated with percutaneous hepatic perfusion with melphalan (M-PHP), by retrospectively pooling data from three centers.. Retrospective analysis including patients ([Formula: see text] 18 years) treated with M-PHP between February 2014 and December 2019 for unresectable liver-dominant or liver-only metastases from UM. Predictors for OS were assessed using uni- and multivariate analyses. Other study outcome measures were response rate, progression-free survival (PFS), liver progression-free survival (LPFS), overall survival (OS) and complications according to CTCAEv5.0.. In total, 101 patients (47.5% males; median age 59.0 years) completed a minimum of one M-PHP. At a median follow-up time of 15.0 months, complete response (CR), partial response (PR), stable disease (SD) and progressive disease were seen in five (5.0%), 55 (54.5%), 30 (29.7%) and 11 (10.9%) patients, respectively, leading to a 89.1% disease control rate. Median PFS, LPFS and OS were 9.0, 11.0 and 20.0 months, respectively. Survival analyses stratified for radiological response demonstrated significant improved survival in patients with CR or PR and SD category. Treatment of the primary tumor with radiotherapy, ≥ 2 M-PHP and lactate dehydrogenase (LDH) < 248 U/L were correlated with improved OS. Thirty-day mortality was 1.1% (n = 2). Most common complication was hematological toxicity (self-limiting in most cases).. M-PHP is safe and effective in patients with UM liver metastases. Achieving CR, PR or SD is associated with improved survival. Primary tumor treatment with radiotherapy, normal baseline LDH and > 1 M-PHP cycles are associated with improved OS.

Percutaneous hepatic chemosaturation is a treatment option for unresectable primary or secondary liver tumors. In this procedure the part of the inferior vena cava (VCI) that collects blood from the hepatic veins is isolated using a double balloon catheter. Like this, systemic distribution of the chemotherapeutic agent melphalan which is administered via the hepatic artery can be prevented. After passage through the liver and drainage from the retrohepatic VCI, the chemosaturated blood passes through two extracorporeal filters. Subsequently, the filtered blood is returned via the jugular vein. The procedure is often accompanied by severe hemodynamic instability, the cause of which is still not completely understood. In addition, coagulation management of extracorporeal circulation is often challenging. The authors report a case in which a thrombus formed in the returning leg of the extracorporeal circulation despite sufficient activated clotting time (ACT). Targeted problem search and resolution were necessary simultaneously to hemodynamic stabilization and interdisciplinary collaboration to successfully perform the intervention and provide the patient with safe treatment.. Die perkutane hepatische Chemosaturation ist eine Behandlungsoption bei nichtresektablen primären oder sekundären Lebertumoren. Dabei wird der Bereich der Lebervenenmündung der Vena cava inferior (VCI) mittels 2 Ballons von der Zirkulation isoliert, sodass die systemische Verteilung des über die Leberarterie applizierten Chemotherapeutikums Melphalan verhindert wird. Nach Passage der Leber und venöser Drainage aus der retrohepatischen VCI durchläuft das chemosaturierte Blut 2 parallel geschaltete extrakorporale Filter. Anschließend wird das gereinigte Blut jugulär rückgeführt. Das Verfahren geht oft mit einer ausgeprägten hämodynamischen Instabilität einher, deren Ursache nicht abschließend geklärt ist. Zusätzlich stellt das Gerinnungsmanagement eine Herausforderung dar. Die Autoren berichten von einem Fall, bei dem sich trotz ausreichender „activated clotting time“ (ACT) ein Thrombus im rückführenden Schenkel der extrakorporalen Zirkulation bildete. Gezielte Problemsuche und -lösung waren parallel zur hämodynamischen Stabilisierung und interdisziplinären Zusammenarbeit notwendig, um die Intervention erfolgreich durchzuführen und der Patientin eine sichere Therapie zukommen zu lassen.

The aim of the study was to evaluate pretreatment inflammatory markers as prognostic factors in patients with unresectable uveal melanoma liver metastases treated with transarterial hepatic chemoperfusion.. 54 patients (44% male, median age: 61 years) were retrospectively assessed. A median of 3 (range: 1-11) treatment sessions were performed with melphalan (92%) or fotemustin (8%). Inflammatory indices were calculated as follows: neutrophils/nl to lymphocytes/nl ratio (NLR), systemic immune-inflammation index ([platelets/nl × neutrophils/nl]/[lymphocytes/nl]; SII), and platelets/nl to lymphocytes/nl ratio (PLR). The cut-off for dichotomization purposes was set at the median (inflammatory indices, hepatic tumor burden) or the upper level of normal. Kaplan Meier analysis was performed for median overall survival (OS) in months, and Cox proportional hazard model for uni(UVA) and multivariate (MVA) hazard ratio (HR, 95%CI) analyses were performed.. Median OS of the study cohort was 7.7 (6.3-10.9) months. In UVA OS was prolonged for low C reactive protein (CRP) (13.5. Pretreatment inflammatory markers (CRP, SII) and AST were independent prognostic survival markers in patients with uveal melanoma liver metastases treated with transarterial hepatic chemoperfusion. A combination of factors may help to identify patients potentially benefitting from treatment.

Percutaneous hepatic melphalan perfusion (PHMP) for the selective treatment of hepatic metastases is known to be associated with procedural hypotension and coagulation disorders. Studies on anesthetic management, perioperative course, complications, and postoperative recovery in the intensive care unit (ICU) have not been published.. In a retrospective observational study, we analyzed consecutive patients who were admitted for PHMP over a 6-year period (2016-2021). Analyses included demographic, treatment, and outcome data with regard to short-term complications until ICU discharge.. Fifty-three PHMP procedures of 16 patients were analyzed. In all of the cases, procedure-related hypotension required the median (range) highest noradrenaline infusion rate of 0.5 (0.17-2.1) μg kg min-1 and fluid resuscitation volume of 5 (3-14) liters. Eighty-four PHMP-related complications were observed in 33 cases (62%), of which 9 cases (27%) involved grade III and IV complications. Complications included airway constriction (requiring difficult airway management), vascular catheterization issues (which resulted in the premature termination of PHMP, as well as to the postponement of PHMP and to the performance of endovascular bleeding control after PHMP), and renal failure that required hemodialysis. Discharge from the ICU was possible after one day in most cases (n = 45; 85%); however, in 12 cases (23%), prolonged mechanical ventilation was required. There were no procedure-related fatalities.. PHMP is frequently associated with challenging cardiovascular conditions and complications that require profound anesthetic skills. For safety reasons, PHMP should only be performed in specialized centers that provide high-level hospital infrastructures and interdisciplinary expertise.

Chemosaturation with percutaneous hepatic perfusion (CS-PHP; Hepatic CHEMOSAT® Delivery System; Delcath Systems Inc, USA) is a novel interventional procedure, which delivers high doses of melphalan directly to the liver in patients with liver tumors while limiting systemic toxicity through hemofiltration of the hepatic venous blood. We have previously shown promising efficacy for patients with ocular melanoma (OM) and cholangiocarcinoma (CCA) within our single-center and multi-center experiences. The aim of this study was to analyze the safety and efficacy of CS-PHP after 141 treatments at Hannover Medical School, Germany.. Overall response rates (ORR) were assessed according to Response Evaluation Criteria In Solid Tumors (RECIST1.1). Median Overall survival (mOS), median progression-free survival (mPFS), and median hepatic PFS (mhPFS) were analyzed using the Kaplan-Meier estimation.. Overall, 60 patients were treated with CS-PHP in the salvage setting from October 2014 until January 2019 at Hannover Medical School with a total of 141 procedures. Half of the patients were patients with hepatic metastases of ocular melanoma (OM) (n = 30), 14 patients had CCA (23.3%), 6 patients had hepatocellular carcinoma (10%), and 10 patients were treated for other secondary liver malignancies (16.7%). In total, ORR and disease stabilization rate were 33.3% and 70.3% (n = 25), respectively. ORR was highest for patients with OM (42.3%), followed by patients with CCA (30.8%). Independent response-associated factors were normal levels of lactate dehydrogenase (odds ratio (OR) 13.7; p = 0.015) and diagnosis with OM (OR 9.3; p = 0.028). Overall, mOS was 9 months, mPFS was 4 months, and mhPFS was 5 months. Patients with OM had the longest mOS, mPFS, and mhPFS with 12, 6, and 6 months, respectively. Adverse events included most frequently significant, but transient, hematologic toxicities (80% of grade 3/4 thrombopenia), less frequently hepatic injury up to liver failure (3.3%) and cardiovascular events including two cases of ischemic insults (5%).. Salvage treatment with CS-PHP is safe and effective particularly in patients OM and CCA. Careful attention should be paid to possible, serious hepatic, and cardiovascular complications.

The potential role of chronic inflammation in the development of cancer has been widely recognized. However, there has been little research fully and thoroughly exploring the molecular link between hepatitis B virus (HBV) and hepatocellular carcinoma (HCC).. To elucidate the molecular links between HBV and HCC through analyzing the molecular processes of HBV-HCC using a multidimensional approach.. First, maladjusted genes shared between HBV and HCC were identified by disease-related differentially expressed genes. Second, the protein-protein interaction network based on dysfunctional genes identified a series of dysfunctional modules and significant crosstalk between modules based on the hypergeometric test. In addition, key regulators were detected by pivot analysis. Finally, targeted drugs that have regulatory effects on diseases were predicted by modular methods and drug target information.. The study found that 67 genes continued to increase in the HBV-HCC process. Moreover, 366 overlapping genes in the module network participated in multiple functional blocks. It could be presumed that these genes and their interactions play an important role in the relationship between inflammation and cancer. Correspondingly, significant crosstalk constructed a module level bridge for HBV-HCC molecular processes. On the other hand, a series of non-coding RNAs and transcription factors that have potential pivot regulatory effects on HBV and HCC were identified. Among them, some of the regulators also had persistent disorders in the process of HBV-HCC including microRNA-192, microRNA-215, and microRNA-874, and early growth response 2, FOS, and Kruppel-like factor 4. Therefore, the study concluded that these pivots are the key bridge molecules outside the module. Last but not least, a variety of drugs that may have some potential pharmacological or toxic side effects on HBV-induced HCC were predicted, but their mechanisms still need to be further explored.. The results suggest that the persistent inflammatory environment of HBV can be utilized as an important risk factor to induce the occurrence of HCC, which is supported by molecular evidence.

In patients undergoing percutaneous liver perfusion with melphalan (M-PHP), the presence of variant hepatic arteries (HAs) may require catheter repositioning and thus prolong procedure time. Coil-embolization of variant HAs may enable M-PHP with a single catheter position as occlusion of variant HAs results in redistribution of flow through preexisting intrahepatic arterial collaterals. We aimed to evaluate whether redistribution of flow has any negative effect on therapeutic response in ocular melanoma patients undergoing M-PHP.. We retrospectively analyzed pretreatment angiograms in all 32 patients that underwent M-PHP between January 2014 and March 2017 for unresectable liver metastases from ocular melanoma. Patients that underwent embolization of a variant left HA (LHA) or middle HA (MHA) during pretreatment angiography followed by at least one technically successful M-PHP were included for further analysis. Redistribution of arterial flow was evaluated on angiography and cone-beam computed tomography (CBCT) images. In each patient, tumor response in liver segments with redistributed blood flow was evaluated using RECIST 1.1 and mRECIST, and then compared with tumor response in segments without flow redistribution. Follow-up scans were reviewed to evaluate progression of liver metastases.. A total of 12 patients were included. Replaced LHA embolization resulted in redistribution of flow to segment(s) 2 (n=3), 2 and 3 (n=5), and 2, 3 and 4 (n=2). MHA embolization resulted in redistribution of flow to segment 4 (n=2). Successful redistribution was confirmed by angiography and/or CBCT in all patients. Tumor response was similar for redistributed and non-redistributed liver segments in 8 out of 9 patients (89%) according to RECIST 1.1, and in 7 out of 8 patients (88%) according to mRECIST. In three patients, tumor response was not evaluable according to RECIST 1.1 or mRECIST as metastases were too small to be categorized as target lesions (n=1), or target lesions were confined to non-redistributed segments (n=2). In one patient, tumor response was not evaluable according to mRECIST as target lesions in the redistributed segments were hypovascular. After a median follow-up time of 17.1 months (range, 9.1-38.5 months), hepatic progression was seen in 9 out of 12 patients with a median time to progression of 9.9 months (range, 2.5-17.7 months). Progression of liver metastases was never seen only in the redistributed liver segments.. Flow redistribution in liver segments by coil-embolization of variant HAs is a feasible technique that does not seem to compromise tumor response in patients undergoing M-PHP.

Metastatic uveal melanoma (UM) carries a poor prognosis; liver is the most frequent and often solitary site of recurrence. Available systemic treatments have not improved outcomes. Melphalan percutaneous hepatic perfusion (M-PHP) allows selective intrahepatic delivery of high dose cytotoxic chemotherapy.. Retrospective analysis of outcomes data of UM patients receiving M-PHP at two institutions was performed. Tumor response and toxicity were evaluated using RECIST 1.1 and Common Terminology Criteria for Adverse Events (CTCAE) v4.03, respectively.. A total of 51 patients received 134 M-PHP procedures (median of 2 M-PHPs). 25 (49%) achieved a partial (N = 22, 43.1%) or complete hepatic response (N = 3, 5.9%). In 17 (33.3%) additional patients, the disease stabilized for at least 3 months, for a hepatic disease control rate of 82.4%. After median follow-up of 367 days, median overall progression free (PFS) and hepatic progression free survival (hPFS) was 8.1 and 9.1 months, respectively and median overall survival was 15.3 months. There were no treatment related fatalities. Non-hematologic grade 3-4 events were seen in 19 (37.5%) patients and were mainly coagulopathic (N = 8) and cardiovascular (N = 9).. M-PHP results in durable intrahepatic disease control and can form the basis for an integrated multimodality treatment approach in appropriately selected UM patients.

Ocular melanoma has a predilection for liver metastases. Systemic treatment is ineffective and the optimal regional therapy approach is poorly defined. Isolated hepatic perfusion (IHP) with melphalan has emerged as a viable treatment option, however a subset of patients are not candidates for this treatment. We therefore sought to determine if melphalan could be safely administered via the hepatic artery for these patients.. A retrospective review of patients treated with hepatic artery infusion (HAI) of melphalan was undertaken. All patients had contraindications to IHP and were without other therapy options. Melphalan infusion was repeated every four weeks with consideration for dose escalation in the absence of toxicity or significant disease progression.. Fourteen patients were treated with HAI of melphalan from 2010 to 2015. All patients had hepatic dysfunction or prohibitive tumor volume precluding IHP. There were no procedure-related complications. Three patients (21%) died within 30 days and the median survival was 2.9 months. Elevated baseline bilirubin > 2.5 mg/dL was associated with worse overall survival (0.93 vs 6.3 months, P < 0.05).. HAI of melphalan is safe and feasible for patients with metastatic ocular melanoma. Further study to determine the optimal utilization of this treatment approach is warranted.

Chemosaturation with percutaneous hepatic perfusion (CS-PHP; hepatic CHEMOSAT. Overall response rates (ORR) were assessed according to response evaluation criteria in solid tumors (RECIST1.1). Overall survival (OS), progression-free survival (PFS), and hepatic PFS (hPFS) were analyzed using the Kaplan-Meier estimation.. 29 patients were treated with CS-PHP as last-line therapy up to five sessions. 19 patients had unresectable hepatic metastases from solid tumors [ocular melanoma (OM) n = 11; colorectal carcinoma n = 2; pancreatic adenocarcinoma n = 2; periampular carcinoma n = 2; breast and endometrial cancer each n = 1] and 10 patients were diagnosed with hepatocellular or cholangiocarcinoma (HCC/CCA). ORR was 19.2%. Patients with OM had the highest ORR (33.3%). Similar to patients with OM, patients with hepatobiliary tumors had durable disease stabilization (40%). Median OS, PFS, and hPFS were 261, 117, and 135 days, respectively. Tumor volume negatively correlated with OS. Complications and toxicities included thrombocytopenia, cardiovascular events, ulcerous bleeding, and edema.. Second-generation CS-PHP seems to be effective and tolerable. Patient selection based on tumor volume and entity is of importance. Particularly, patients with OM and hepatobiliary tumors represent promising candidates for CS-PHP.

Hepatic arterial infusion chemotherapy (HAIC) is an option for patients with liver-predominant metastatic breast cancer (LMBC), when no further systemic treatment is available. But systematic reports are limited. Here we conducted a retrospective analysis of LMBC patients treated at an expert center.. Individual patient data were retrieved from the clinical data base of the West German Cancer Center. Primary endpoints included hepatic response (RECIST), progression-free survival (PFS), overall survival (OS), and toxicity. A score based on LDH, AST, ALT and bilirubine was developed to estimate the hepatic metastasis load.. Data from 70 consecutive patients were included. All patients were heavily pretreated (median 7 treatment lines for LMBC). HAIC protocols included mitomycin/5-FU (70%), mitomycin (14.3%), melphalan (12.9%) and 5-FU (7.1%), with selection based on patient characteristics. Partial hepatic remission was obtained as best response in 14 patients (20.0%), stable disease in 27 patients (38.6%), and progressive disease in 29 patients (41.4%). Median PFS and OS from initiation of HAIC were 2 (range 0-10) and 7 months (range 1-37). Mainly hepatic and hematopoietic HAIC-related toxicities were observed; there was no treatment-related death. The hepatic metastasis score effectively separated two prognostic groups: Patients with a score <3 had significantly superior PFS (15 vs 7 weeks, p = 0.017) and OS (12 vs 5 months, p = 0.002).. HAIC offers a safe and effective salvage treatment strategy in heavily pretreated patients with LMBC and no further treatment options. The hepatic metastasis score may help to identify patients with sustained clinical benefit.

Percutaneous isolated hepatic perfusion (PIHP) with Melphalan has been developed as a treatment for patients with isolated hepatic metastases of uveal melanoma. We discuss patient outcome and safety in a retrospective multi-centre study.. Between 2012 and 2016 18 patients with un-resectable isolated hepatic metastases of uveal melanoma received single or repeated PIHP with Melphalan (n = 35) at seven sites. Progression-free time, overall survival time (OS) and tumour response by means of RECIST 1.1 criteria were evaluated. Peri- and post-procedural adverse events (AE) were registered. Patients' life quality was assessed using four-point scale questionnaires.. Of 18 patients, initial PIHP treatment resulted in partial response (PR) in eight, stable disease (SD) in seven and progressive disease (PD) in three cases. Nine patients underwent second PIHP with PR in eight cases and PD in one case. Six patients were evaluated after third PIHP with PR in five patients and SD in one patient. Two patients received fourth PIHP with PD in both cases. Median OS was 9.6 months (range 1.6-41.0 months). Median progression-free survival time was 12.4 months (range 0.9-41.0 months) with 1-year survival of 44%. Most common post-procedural AE grade 3 and 4 were temporary leukopenia (n = 11) and thrombocytopenia (n = 8). Patients' self-assessments showed good ratings for overall health and quality of life with only slight changes after PIHP, and a high degree of satisfaction with PIHP treatment.. PIHP with Melphalan proved to be a relatively safe, minimal-invasive and repeatable treatment for patients with non-resectable hepatic metastases of uveal melanoma.

This report describes the outcomes and long-term follow-up data from all isolated hepatic perfusions (IHPs) performed at a single institution in Sweden between the years 1989 and 2013 for patients with isolated uveal melanoma metastases.. A total of 68 patients (median age, 61 years) were treated consecutively at Sahlgrenska University Hospital. Of the 68 patients, 67 % had fewer than 10 tumors. The median diameter of the largest lesion was 2.5 cm. The patients underwent IHP with either melphalan alone or the addition of either tumor necrosis factor-alpha or cisplatin. The response was assessed after 8-12 weeks by computed tomography or magnetic resonance imaging.. The overall response rate was 67 and 20 % of the patients had a complete response. The median times to local and systemic progression were respectively 10 and 14 months. The prognostic factors for time to local recurrence were response and number of tumors. The median survival time was 22 months. The prognostic factors for survival were response, largest tumor diameter, and number of tumors. Five patients (7 %) died within 30 days, and six patients (9 %) experienced major complications (Clavien-Dindo 3/4).. Isolated hepatic perfusion is a treatment option with high response rates and tolerable mortality and morbidity. Whether IHP has a survival benefit compared with other treatment options currently is being investigated in a randomized trial.

Unresectable liver metastases of colorectal cancer can be treated with systemic chemotherapy, aiming to limit the disease, extend survival or turn unresectable metastases into resectable ones. Some patients however, suffer from side effects or progression under systemic treatment. For patients with metastasized uveal melanoma there are no standard systemic therapy options. For patients without extrahepatic disease, isolated liver perfusion (IHP) may enable local disease control with limited systemic side effects. Previously, this was performed during open surgery with satisfying results, but morbidity and mortality related to the open procedure, prohibited a widespread application. Therefore, percutaneous hepatic perfusion (PHP) with simultaneous chemofiltration was developed. Besides decreasing morbidity and mortality, this procedure can be repeated, hopefully leading to a higher response rate and improved survival (by local control of disease). During PHP, catheters are placed in the proper hepatic artery, to infuse the chemotherapeutic agent, and in the inferior caval vein to aspirate the chemosaturated blood returning through the hepatic veins. The caval vein catheter is a double balloon catheter that prohibits leakage into the systemic circulation. The blood returning from the hepatic veins is aspirated through the catheter fenestrations and then perfused through an extra-corporeal filtration system. After filtration, the blood is returned to the patient by a third catheter in the right internal jugular vein. During PHP a high dose of melphalan is infused into the liver, which is toxic and would lead to life threatening complications when administered systemically. Because of the significant hemodynamic instability resulting from the combination of caval vein occlusion and chemofiltration, hemodynamic monitoring and hemodynamic support is of paramount importance during this complex procedure.

An increasing number of children with advanced malignancies have recently received high-dose chemotherapy (HDC) with hematopoietic stem cell transplantation (HSCT), followed by surgery. In this study, we reviewed our experience with surgery after HDC and autologous (auto) or allogeneic (allo) HSCT to elucidate the problems associated with this treatment and establish the optimum surgical management strategy.. We retrospectively reviewed the cases of 24 children with advanced malignancy treated with HDC and HSCT before tumor resection at our institution. The tumors included 18 neuroblastomas, 5 soft tissue sarcomas, 2 hepatoblastomas, and 1 Wilms tumor. The source of hematopoietic stem cells was auto-HSCT in 19 patients and allo-HSCT in 5 patients. To be able to undergo surgery, it was necessary that the patient's general condition, including hemostasis, should be fairly good and that the results of hematological examinations should include a white blood cell (WBC) count of>1,000/µL, hemoglobin level of>10 g/dL and platelet count of>5 × 10(4)/µL.. The mean duration before WBC recovery after HSCT was 14.5 ± 1.4 days after auto-HSCT and 23.8 ± 1.2 days after allo-HSCT, respectively (p<0.01). The mean duration before platelet recovery after HSCT was 46.5 ± 5.2 days for auto-HSCT and 48.6 ± 5.5 days for allo-HSCT (not significant [n.s.]). The mean interval between allo-HSCT and surgery was significantly longer (92.8 ± 6.2 days) than that between auto-HSCT and surgery (57.0 ± 3.9 days) (p<0.01), likely because of the use of steroids and immunosuppressants after HSCT. The tumors were completely resected in all cases without severe complications. All the patients treated with allo-HSCT had an acute graft versus host (aGVH) reaction at 2 to 3 weeks after HSCT, and specifically required the administration of steroids and immunosuppressants to prevent aGVH. The postoperative complications included paralytic ileus in two cases and a tacrolimus-associated encephalopathy in one case involving allo-HSCT. In half of the patients, the WBC count was not elevated after surgery, whereas the postoperative serum C-reactive protein (CRP) level was elevated in all cases.. Our data indicate that surgical treatment can be safely performed even after HDC with HSCT if attention is paid to myelosuppression and the adverse effects of both chemotherapeutic agents and immunosuppressants.

Isolated hepatic perfusion (IHP) is a procedure where the liver is surgically isolated and perfused with a high concentration of the chemotherapeutic agent melphalan. Briefly, the procedure starts with the setup of a percutaneous veno-venous bypass from the femoral vein to the external jugular vein. Via a laparotomy, catheters are then inserted into the proper hepatic artery and the caval vein. The portal vein and the caval vein, both supra- and infrahepatically, are then clamped. The arterial and venous catheters are connected to a heart lung machine and the liver is perfused with melphalan (1 mg/kg body weight) for 60 min. This way it is possible to locally perfuse the liver with a high dose of a chemotherapeutic agent, without leakage to the systemic circulation. In previous studies including patients with isolated liver metastases of uveal melanoma, an overall response rate of 33-100% and a median survival between 9 and 13 months, have been reported. The aim of this protocol is to give a clear description of how to perform the procedure and to discuss IHP as a treatment option for liver metastases of uveal melanoma.

A new melphalan hemoperfusion filter (GEN 2) was evaluated in a simulated-use porcine model of percutaneous hepatic perfusion (PHP). The current study evaluated melphalan filtration efficiency, the transfilter pressure gradient, and the removal of specific blood products.. A porcine PHP procedure using the GEN 2 filter was performed under Good Laboratory Practice conditions to model the 60-min clinical PHP procedure.. The mean filter efficiency for removing melphalan in six filters was 99.0 ± 0.4 %. The transfilter pressure gradient across the filter averaged 20.9 mmHg for the 60-min procedure. Many blood components, including albumin and platelets, decreased on average from 3.55 to 2.02 g/dL and from 342 to 177 × 10.e3/μL, respectively, during the procedure.. The increased melphalan extraction efficiency of the new filter is expected to decrease systemic melphalan exposure. In addition, the low transfilter pressure gradient resulted in low resistance to blood flow in the GEN 2 filter, and the changes to blood components are expected to be clinically manageable.

The poor prognosis of children with high-grade glioma (HGG) and high-risk neuroblastoma, despite multidisciplinary therapeutic approaches, demands new treatments for these indications. F14512 is a topoisomerase II inhibitor containing a spermine moiety that facilitates selective uptake by tumor cells via the Polyamine Transport System (PTS) and increases topoisomerase II poisoning. Here, F14512 was evaluated in pediatric HGG and neuroblastoma cell lines. PTS activity and specificity were evaluated using a fluorescent spermine-coupled probe. The cytotoxicity of F14512, alone or in combination with ionizing radiation and chemotherapeutic agents, was investigated in vitro. The antitumor activity of F14512 was assessed in vivo using a liver-metastatic model of neuroblastoma. An active PTS was evidenced in all tested cell lines, providing a specific and rapid transfer of spermine-coupled compounds into cell nuclei. Competition experiments confirmed the essential role of PTS in the cell uptake and cytotoxicity of F14512. This cytotoxicity appeared greater in neuroblastoma cells compared with HGG cells but appeared independent of PTS activity levels. In vivo evaluation confirmed a marked and prolonged antitumoral effect in neuroblastoma cells. The combinations of F14512 with cisplatin and carboplatin were often found to be synergistic, and we demonstrated the significant radiosensitizing potential of F14512 in the MYCN-amplified Kelly cell line. Thus, F14512 appears more effective than etoposide in pediatric tumor cell lines, with greater efficacy in neuroblastoma cells compared with HGG cells. The synergistic effects observed with platinum compounds and the radiosensitizing effect could lead to a clinical development of the drug in pediatric oncology.

Evidence suggests that paeoniflorin may be involved in anticancer activities. Here, we have investigated the effects of paeoniflorin and correlative mechanisms on anti-invasion and anti-metastasis in human hepatocellular carcinoma (HCC) cell lines.. In the current study, we have applied 3-(4,5-dimethylthiazol-2-yl)-2, 5-diphenyl tetrazolium bromide (MTT) assay to determine the proliferative effect of HepG2 and Bel-7402, two human hepatoma cell lines, and we have established a boyden chamber assay, a wound healing assay and cell adhesion assay to detect and quantify the invasion, metastasis and adhesion of both HepG2 and Bel-7402. In addition, we have analyzed the protein expression of matrix metalloproteinas (MMP)-9, E-cadherin (E-cad) and extracellular signal-regulated kinase (ERK) in both cell lines through western blot analysis.. Paeoniflorin (6. 25-200 µM) had inhibitory effect on the growth of HepG2 and Bel-7402 cell lines, and reduced significantly invasion, metastasis and adhesion of HCC cell lines. In addition, paeoniflorin decreased the expression of MMP-9 and ERK in HepG2 and Bel-7402 cells, and increased expression of E-cad in both cell lines.. Paeoniflorin is effective anti-metastatic and anti-invasive agent for suppressing HCC invasion and metastasis (Fig. 5, Ref. 30).

The goal of this study was to determine whether liver, gastric, or colonic cancer may be suitable targets for chemosaturation therapy with percutaneous hepatic perfusion (CS-PHP) and to assess the feasibility of utilizing other cytotoxic agents besides melphalan in the CS-PHP system.. Forty human cell lines were screened against three cytotoxic chemotherapeutic agents. Specifically, the dose-dependent effect of melphalan, oxaliplatin, and paclitaxel on proliferation and apoptosis in each cell line was evaluated. These agents were also evaluated for their ability to induce apoptosis in normal primary human hepatocytes. A high-dose short-term drug exposure protocol was employed to simulate conditions encountered during CS-PHP.. The average concentration of melphalan required for inducing significant apoptosis was 61 μM, or about 3-fold less than the theoretical concentration of 192 μM, achieved in the hepatic artery during CS-PHP dosing with melphalan. Additionally, we found that gastric cancer cell lines were 2-5 fold more sensitive to apoptosis than liver cancer cell lines to all three compounds, suggesting that in addition to colonic and gastric cancer metastases to the liver, primary gastric cancer may also be amenable to management by CS-PHP using an appropriate therapeutic agent. Significantly, at concentrations that are predicted using the CS-PHP system, these agents caused apoptosis of colonic, gastric, and liver cancer cells but were not toxic to primary human hepatocytes.. The compounds tested are potential candidates for use in the CS-PHP system to treat patients with gastric and colonic metastases, and primary cancer of the liver.

The low molecular weight of many chemotherapeutics causes their untargeted distribution in the body and fast renal clearance, which leads to a loss of therapeutic activity and to unspecific toxic side effects. Therefore, there is a growing interest in conjugating anticancer drugs to water soluble polymers and thus, take advantage of the 'enhanced permeability and retention' (EPR) effect in tumors. In this study, water soluble polyphosphoesters were used as polymer carriers of melphalan hydrochloride (hydrochloride of p-bis(2-chloroethyl)amino-L-phenylalanine), which is a multifunctional alkylating agent. Melphalan was chemically immobilized by covalent bonding to poly(oxyethylene H-phosphonate) under Atherton-Todd reaction conditions. Novel polymer-melphalan complexes with ionic and hydrogen bonds were designed as controls, basing on two other biodegradable polyphosphoesters: poly(hydroxyoxyethylene phosphate) and poly(methyloxyethylene phosphate). The structure of the formed products was elucidated by (1)H, (13)C, (31)P NMR and FT-IR spectroscopy. The cytotoxic effect of the melphalan formulations was evaluated on different tumor cell lines. The novel polymer formulations showed a concentration dependent antitumoral activity, comparable to the effect of unmodified melphalan. The polymer-melphalan conjugate was also evaluated in vivo in the human hepatocellular carcinoma HuH7 xenograft mouse model. It improved the therapeutic efficacy of pure melphalan without causing side effects.

Whereas surgical resection is the only curative treatment for liver tumors, effective treatment for isolated unresectable lesions when there is tumor progression in spite of several lines of chemotherapy remains to be found. We report herein two cases of patients treated by a 1-hour Hyperthermic Isolated Liver Perfusion (HILP) with a combination of melphalan and bevacizumab leading to complete response. The first patient had liver metastases secondary to previously resected malignant glucagonoma and the second, recurrent hepatocellular carcinoma. We used bevacizumab in association with melphalan for HILP because of the additional effect of an anti-VEGF antibody in these highly vascularized tumors and its locally restricted delivery to the isolated hepatic vascular compartment despite of its classic contraindication in association with surgery. The protocol was approved by the Ethics Committee. Enhanced CT scans during follow-up showed complete tumor necrosis as early as the second postoperative day. Patients had 27 and 7 months disease-free survival and 48 and 41 months overall survival after HILP, for neuroendocrine liver metastases and HILP plus liver transplantation for HCC respectively. Under very specific conditions, bevacizumab in HILP can provide excellent tumor response in hopeless clinical cases of liver tumors.

The aim of this retrospective study was to analyze the outcome and identify risk factors associated with progression-free survival (PFS) in 36 children with high-risk neuroblastoma who underwent autologous peripheral blood progenitor cell (PBPC) transplantation between 1994 and 2010. The conditioning regimen used in all cases consisted of high-dose of busulfan and melphalan. Median age at transplantation was 3 years (range: 0.7-14 years). The median times to neutrophil and platelet engraftment were 11 days (range: 9.16 days) and 13 days (range: 9.33), respectively. Twenty-one patients developed nonhematologic toxicity: 15 patients had mucositis, 4 patients developed an engraftment syndrome, and there were 2 cases of liver toxicity. No toxic deaths were observed. There were 15 patients who relapsed. The median time to relapse was 6 months after the transplant (range: 3-13 months). With a median follow-up of 55 months (range: 4-180 months), the PFS was 57% ± 8.5% for the whole group. In multivariate analysis, age below 3 years (P < .005), complete remission (CR) pretransplantation (P < .07) and 1p germline status (P < .01) were variables associated with better outcomes. Patients who were or achieved early CR following transplantation (3 months posttransplantation) had a probability of PFS of 91% ± 6% as compared to patients who did not (PFS 9% ± 8%) (P < .0001). This retrospective study shows that high dose of busulfan and melphalan as conditioning regimen in children with high-risk neuroblastoma is associated with very low morbidity and no mortality in the authors' hands. Younger patients with no 1p deletions and in first CR at transplantation had the better outcome.

To assess the survival of patients with hepatic uveal melanoma metastases undergoing sequential transarterial hepatic chemoperfusion.. 61 patients (mean age, 60.3 ± 13.8 y) underwent a total of 249 hepatic chemoperfusion procedures (mean: 4 chemoperfusion procedures; range, 1-7 chemoperfusion procedures; standard deviation, 2.3 chemoperfusion procedures). All patients started with melphalan. In the case of progressive disease, melphalan was replaced by a different chemoperfusion agent. 38 patients were treated with melphalan only, 23 patients were treated with a combination of melphalan and other drugs. The median overall survival time was calculated for the overall population and several sub-groups. Differences in the survival rate between the sub-groups were assessed for statistical significance. The complication rate was assessed.. The median overall survival of the entire population was 10 months. The patients in the subgroups with a maximum number of 9 hepatic metastases as well as the patients in the subgroup without extrahepatic metastases at the beginning of therapy survived significantly longer than patients with more than 9 metastases/extrahepatic metastases (p = 0.019, p = 0.008). One patient (0.4%) died from liver failure after initial infusion of melphalan.. Intraarterial sequential hepatic chemoperfusion offers a minimally invasive treatment in patients with hepatic uveal melanoma metastases with good survival times and an acceptable major complication rate.

Patients with ocular melanoma liver metastases have a poor prognosis, treatment options are limited, and median survival is less than 1 year. In this study, we characterized the early molecular changes that occur in tumors immediately after vascular isolation perfusion with melphalan with hyperthermia in patients with hepatic metastases from ocular melanoma.. Patients underwent treatment on a clinical trial using a 60-min hyperthermic isolated hepatic perfusion (IHP) with melphalan. Microarray analysis was performed in 28 tumor samples obtained intraoperatively of which 12 were pre- and 16 were post-IHP. Various statistical analyses were performed to identify differentially expressed genes and gene categories between the groups.. Median survival of 17 treated patients was 11.9 months. Unsupervised hierarchical clustering of all tumors resulted in separation of pre and post-IHP samples into two distinct groups. Analysis of genes showed that the Ras GTPase activator, ecotropic viral integration site 5 (EVI5), and several other melanoma-associated genes were overexpressed in pre-IHP tumors. In post-IHP samples the overexpression of a DNA replication associated gene, replication factor C (RFC5), was significantly associated with shortened survival (P < 0.003). Other major gene ontology categories identified in the post-IHP tumor samples were DNA-directed RNA polymerase activity and chromatin remodeling, both important categories involved in DNA replication and repair.. These results demonstrate that acute changes in gene expression patterns occur in tumors immediately after treatment with melphalan administered via hyperthermic IHP. Rapid activation of DNA synthesis and repair pathways may be a mechanism of acquired tumor resistance in patients with ocular melanoma.

Ocular melanoma prefers to metastasize to the liver and the liver is the sole site of metastatic disease in 80% of patients. Until now there has been no standard treatment available and these patients have a very poor prognosis (median survival 2-5 months). Isolated hepatic perfusion may be an option in patients with irresectable hepatic ocular melanoma metastases. The aim of this study was to evaluate applicability, toxicity and response in this selected group of ocular melanoma patients by treatment with isolated hypoxic hepatic perfusion with retrograde outflow (IHHP) with melphalan.. From September 2002 until July 2006 eight consecutive patients were included in this study. IHHP was performed with inflow via the hepatic artery and retrograde outflow via the portal vein during 25 min with 1mg/kg melphalan. The perfusion was followed by a complete wash-out procedure.. The median total operation time was 4h with a median blood/fluid loss of 1100 ml. No postoperative mortality was observed. Median hospital stay was 9.5 days. Toxicity was moderate: WHO grade 3 leukocytopenia in 3 patients, grade 3 hepatic toxicity in 1 patient. In 37% of patients (3/8) a partial response could be demonstrated 3 months after IHHP. Stable disease was found in 3 patients and progressive disease in 2 patients. Median time to local progression was 6 months and the median survival was 11 months.. Melphalan-based IHHP with retrograde outflow is a safe treatment option for patients with irresectable ocular melanoma metastases. Survival benefit seems to be comparable to classical IHHP.

Focal nodular hyperplasia (FNH) is a benign, poorly understood hepatic tumor that is rare in children. Although there is no evidence for malignant degeneration, FNH can occur adjacent to a malignancy. Here, the case of a 4-year-old boy with a hepatic mass and history of stage IV neuroblastoma is presented. Initial imaging and core-needle biopsy were consistent with FNH. However, after left lateral segmentectomy, pathologic examination revealed a malignant tumor most consistent with small cell undifferentiated hepatoblastoma as well as 3 foci of FNH in the surrounding parenchyma.

Percutaneous hepatic perfusion (PHP), a regional cancer therapy, entails insertion of percutaneous catheters to isolate hepatic vasculature and enable simultaneous hepatic venous hemofiltration of high-dose chemotherapy. PHP has been shown to be safe and to benefit some patients with liver metastases.. We examined hemodynamic and metabolic changes as well as anesthetic implications during PHP in patients with metastatic liver cancer enrolled in clinical trials of escalating doses of melphalan between 2001 and 2006.. Fifty-one patients underwent 136 PHPs with general anesthesia. Diagnoses included neuroendocrine tumors, melanoma, and metastatic carcinomas. Based upon available data derived from all procedures, incorporating multiple procedures per patient, after occlusion of the inferior vena cava and during hepatic perfusion, there were decreases in mean arterial (-15.4 +/- 1 and -7.4 +/- 1 mmHg, respectively) and central venous pressure (-5.4 +/- 0.3 and -5.6 +/- 0.3 mmHg) and increases in heart rate (11 +/- 1 and 13.4 +/- 0.9 bpm) (all p < 0.0001) which resolved with completion of the procedure. During vascular isolation, patients received norepinephrine (13% of procedures), phenylephrine (70%), or both agents (11%). During hepatic perfusion with melphalan, compared to baseline, there were decreases in pH (-0.09 +/- 0.01) and bicarbonate (-3.3 +/- 0.6 mmol/L) (both p < 0.0001) and, upon completion of procedure, increases (2.6 +/- 0.4 mmol/L) in bicarbonate, compared to values during hepatic perfusion (p < 0.0001).. PHP therapy can be associated with transient but significant hemodynamic and metabolic perturbations. In order to assure patient comfort and facilitate timely diagnosis and treatment of associated hemodynamic and metabolic changes, we favor administration of general anesthesia, rather than sedation, for patients undergoing PHP.

Isolated hepatic perfusion with high-dose chemotherapy is a treatment option for patients with irresectable metastases confined to the liver. Prolonged local control and impact on survival have been claimed. Major drawbacks are magnitude and costs of the procedure. We developed an isolated hypoxic hepatic perfusion (IHHP) with retrograde outflow without the need for a heart-lung machine.. Twenty-four consecutive patients with irresectable metastases of various origins were treated. IHHP inflow was via the hepatic artery, outflow via the portal vein with occlusion of the retrohepatic caval vein. Radiolabeled albumine was used for leakage monitoring. Melphalan was used at 1-2 mg/kg. A 25-minute perfusion period was followed by a complete washout. Local and systemic melphalan concentrations were determined.. Compared with oxygenated classical IHP, the IHPP procedure reduced operation time from >8 h to 4 hours, blood loss from >4000 to 900 cc and saved material and personnel costs. Leakage was 0% with negligible systemic toxicity and 0% perioperative mortality. Tumor response: complete response (CR) in 4%, partial response (PR) in 58%, and stable disease (SD) in 13%. Median time to progression was 9 months (2-24 months); pharmacokinetics demonstrated intrahepatic melphalan concentrations more than 9 fold higher than postperfusion systemic concentrations.. IHPP is a relatively simple procedure with reduced costs, reduced blood loss, no mortality, limited toxicity, and response rates comparable to classic IHP. The median duration of 9 months of tumor control should be improved. Hereto, vasoactive drugs, will be explored in further studies.

The aim of this study was to identify prognostic factors for local and systemic failure after isolated hepatic perfusion (IHP) with 200 mg melphalan in patients with colorectal liver metastases.. Hundred and fifty-four patients were selected for IHP and underwent laparotomy. Patients were monitored for response, toxicity and survival. Univariate and multivariate analyses were carried out to identify prognostic factors for hepatic response and progression-free and overall survival.. Hepatic response rate was 50% with a median progression-free and overall survival of, respectively, 7.4 and 24.8 months. In multivariate analyses, absence of ability to perfuse through the hepatic artery (P = 0.003), severe postoperative complications (P = 0.048) and >10 liver metastases (P = 0.006) adversely influenced overall survival and no adjuvant chemotherapy adversely influenced progression-free survival.. This is the first study to report prognostic factors for survival after IHP. Possibly, overall and disease-free survival can increase if preoperative screening is improved. In future studies on IHP, adjuvant chemotherapy should be considered.

The objective was to analyze the outcome of three treatment strategies using isolated hyperthermic liver perfusion (IHP) with melphalan for liver metastases of malignant melanoma. It was designed as an exploratory study. The setting was a single-center study in a university hospital. The study was carried out on 27 patients. IHP was used with modifications during three different time periods (IHP I, IHP II and IHP III), in technique and temperature (amount of melphalan: 0.5, 1.0 and 2 mg/kg body weight in the perfusate; 41, 40 and 40 degrees C). Tumor response was estimated according to WHO criteria with computed tomography or MRI. Mortality and morbidity were secondary measures. Six of 11 patients in the IHP I cohort experienced a partial response (PR). In the IHP II cohort, two patients of 11 experienced a complete response and five a PR. In the IHP III cohort, five of five patients experienced a PR. Six postoperative deaths were reported (27%) (three in the IHP I and three in the IHP II series), secondary to liver insufficiency and multiorgan failure. Treatment of liver metastases of malignant melanoma with isolated hyperthermic melphalan perfusion has shown an impressive tumor response rate, which seems to be higher than the response rates reported for other systemic chemotherapy regimens. The maximum tolerated dose for melphalan in the perfusate was surpassed with a 2 mg/kg body weight. By modifying the technique and restricting the allowed tumor burden, the response rate remained high and the mortality was reduced.

Isolated hepatic perfusion (IHP) offers the advantage of high local drug exposure with limited systemic toxicity. To increase local drug exposure, we administered melphalan at a reduced flow in the hepatic artery during IHP (hepatic artery infusion, hepatic artery-portal vein perfusion, HI-HPP). Between December 2001 and December 2004, 30 patients with colorectal cancer liver metastases underwent HI-HPP with 200mg melphalan. Samples of the perfusate were taken for pharmacokinetic analysis. Patients were monitored for response, toxicity and survival. Perfusion was aborted prematurely in 2 patients due to leakage. During melphalan administration in the hepatic inflow cannula a mean flow rate of 121.3 mL/min and mean pressure of 62.5mm Hg were achieved. One patient died within 30 days after HI-HPP. Four patients developed veno-occlusive disease (VOD), while 2 patients showed signs of VOD. Twelve patients showed hepatic response, with a median duration of response of 11.5 months, according to WHO criteria. Although HI-HPP results in high perfusate melphalan concentration levels, it is associated with a relatively high level of hepatotoxicity and a limited response rate. We believe that the low flow and pressure rates found in this study can result in reduced drug penetration of the tumour and thus limited tumour response.

We have investigated a rapidly reversible hydrophobization of therapeutic agents for improving first-pass uptake in locoregional drug therapy. This approach involves the attachment of a hydrophobic moiety to the drug by highly labile chemical linkages that rapidly hydrolyze upon injection. Hydrophobization drastically enhances cell-membrane association of the prodrug and, consequently, drug uptake, while the rapid lability protects nontargeted tissues from exposure to the highly active agent. Using the membrane-impermeable DNA intercalator propidium iodide, and melphalan, we report results from in vitro cellular internalization and toxicity studies. Additionally, we report in vivo results after a single liver arterial bolus injection, demonstrating both tumor targeting and increased survival in a mouse tumor model.

Irinotecan given with 5-fluorouracil and leucovorin is currently used as first-line therapy for patients with metastatic colorectal cancer (CRC). However, the response duration is <1 year, and second-line systemic chemotherapy has limited efficacy. We analyzed the efficacy of isolated hepatic perfusion (IHP) for patients with progressive CRC liver metastases after irinotecan.. Between March 1993 and February 2003, 124 patients with CRC liver metastases underwent IHP on institutional review board-approved protocols. The overall treatment mortality was 4% (5 of 124). Twenty-five patients (10 women and 15 men; mean age, 53 years) were identified who had progressive liver metastases by carcinoembryonic antigen, imaging studies, or both after irinotecan. A 1-hour hyperthermic IHP (mean hepatic temperature, 40.0 degrees C) with melphalan 1.5 mg/kg (mean total dose, 100 mg) was administered via laparotomy. Perfusion with an oxygenated extracorporeal circuit was established with inflow via a cannula in the gastroduodenal artery and common hepatic artery inflow occlusion. Outflow was via a cannula in an isolated segment of the inferior vena cava. During IHP, portal and inferior vena caval flow were shunted to the axillary vein. Patients were assessed for radiographical response, recurrence pattern, and survival.. The mean number of prior irinotecan cycles in 25 patients was 6 (range, 2-14), and it was given primarily as second-line therapy. The median number of liver metastases before IHP was 10 (range, 1-50), and the median percentage of hepatic replacement by tumor was 25%. The mean operative time was 9 hours (range, 6-12 hours), and the median hospital stay was 11 days (range, 8-76 days). There was 1 complete response and there were 14 partial responses in 25 patients (60%), with a median duration of 12 months (range, 5-35 months). Disease progressed systemically in 13 of 25 patients at a median of 5 months (range, 3-16 months). The median overall survival was 12 months (range, 1-47 months), and the 2-year survival was 28%.. For patients with progressive CRC liver metastases after irinotecan, IHP has good efficacy in terms of response rate and duration. Continued evaluation of IHP with melphalan as second-line therapy in this clinical setting is justified.

Locoregional treatments like photodynamic therapy (PDT), radiofrequency ablation (RFA) or hepatic artery infusion (HAI) of chemotherapeutics may be applied for unresectable colorectal liver metastases. We evaluated the effect of these treatments on the immune response in a rat colon tumour liver metastases model.. Wag/Rij rats were inoculated at day 0 with CC531 tumour cells at two sites in the liver. At day 15, one of two tumours was treated with RFA or PDT, or the liver was treated by HAI. Twelve days later (day 27), rats were rechallenged locally with CC531 cells in the liver or systemically with CC531 cells in the femoral vein. At day 42, tumour growth in liver and lungs was determined.. RFA, PDT and HAI were very effective in liver tumour eradication, but following RFA or PDT there was no inhibitory effect on untreated nearby liver tumours. Outgrowth after local rechallenge was, however, significantly inhibited in RFA-, PDT- and HAI-treated rats, whereas all control rats showed outgrowth of a third liver tumour. After systemic rechallenge, control rats developed lung metastases whereas treated rats did not, but this difference was not statistically significant.. These results show that following PDT, RFA and HAI resistance to local and possibly systemic tumour rechallenge is increased. This may be partly due to the induction or enhancement of a cellular immune response.

Primary hepatocellular carcinoma is one of the most common malignancies worldwide. Isolated hepatic perfusion (IHP) is a regional treatment technique that isolates the organ to allow delivery of high-dose chemotherapy, biological agents, and hyperthermia directly to unresectable cancers confined to the liver. This study presents our experience using IHP with melphalan with or without tumor necrosis factor (TNF) to treat patients with hepatocellular carcinoma or adenocarcinoma of hepatobiliary origin. Nine patients with unresectable primary hepatic malignancies underwent a 60-minute IHP with 1.5 mg/kg melphalan with or without 1.0 mg TNF. Four patients failed one or more previous treatment regimens, and the mean hepatic replacement by tumor was 41% (range 10% to 75%). Patients were monitored for response, toxicity, time to recurrence, and survival. Six (67%) of nine patients experienced greater than 50% regression of tumor by objective radiographic imaging and an additional patient had a 45% reduction in tumor burden. Mean time to progression was 7.7 months for those who responded to treatment. Patients who had a response to therapy had an average overall survival of 16.3 months. IHP can be performed safely and has significant antitumor activity in patients with unresectable primary hepatic malignancies. Hepatic progression continues to be the dominant factor influencing survival in this group of patients.

Melphalan is a chemotherapeutic drug that exerts its cytotoxic effect mainly through the formation of DNA adducts. We report the specific immunohistochemical detection and visualisation of melphalan-DNA adducts using the monoclonal antibody MP5/73 in cultured tumour cells and solid tumour tissue from colorectal liver metastases from patients treated with melphalan. The human colon cancer cell lines HT29, SW480 and SW1116, and the rat colon cancer cell line CC531 were exposed to different concentrations of melphalan. In addition, tumour samples from 17 patients with colorectal liver metastases treated by isolated hepatic perfusion with high dose melphalan (200mg) were collected. Cell lines and tumour samples were stained with the MP5/73 antibody against melphalan-DNA adducts and cell viability was determined by an MTT assay. Melphalan-DNA adducts could be visualised by immunohistochemistry in both cultured cells and solid tumour tissue. A correlation between melphalan exposure concentration, the subsequent melphalan-DNA adduct staining intensity, and melphalan cytotoxicity existed for each individual cell line, but the level of both parameters independently differed between cell lines. Specific staining for melphalan-DNA adducts also was feasible in the human solid tumour tissue. There was considerable variation in melphalan-DNA adduct staining, staining intensity, and distribution in the tumour stroma and the tumour epithelium among the different patients. Melphalan-DNA adducts appeared to be more intense in tumour cells at the border of the tumour nodules than in tumour cells in the centre. Thus, visualisation of melphalan-DNA adducts by immunohistochemistry allows the study of distribution of melphalan-DNA adducts in solid tumours.

An 8-year-old female Shetland sheep dog had hyperproteinemia with a monoclonal gammopathy and a solid mass on the liver, which was histologically diagnosed as a plasma cell tumor. After the treatment of surgery and chemotherapy, serum protein level reduced to the normal range and the gammopathy was disappeared. These findings indicate the plasma cell tumor developed primarily from the liver.

Isolated hepatic perfusion (IHP) is a recently reconsidered locoregional approach for unresectable primary or metastatic cancer and encouraging results have been achieved from its clinical application. Ten patients underwent hyperthermic IHP with melphalan. There was no intraoperative mortality. In the postoperative period two patients died due to multi-organ failure. Four patients had significant but transient hepatic toxicity. In 8 assessable patients, the overall response rate was 63%. We observed objective tumor regression in a significant percentage of patients refractory to standard treatments. Locoregional toxicity was significant, which underscores the need for a more accurate preoperative evaluation of hepatic function.

The optimum conditions (duration and concentration) of a fixed dose, intra-arterial melphalan infusion in relation to its antitumor effect and toxicity in the liver were investigated in a rat colon tumor model (CC531) of liver metastases. We studied the difference in tumor and liver uptake, as well as antitumor effect and hepatotoxicity after 5- and 20-min hepatic arterial infusion (HAI) of a fixed melphalan dose. Melphalan content in perfusate, liver, and tumor tissue was analyzed by high-performance liquid chromatography. The antitumor effect and hepatotoxicity in rats treated either systemically or with 5- and 20-min HAI, with a fixed dose melphalan (4.4 micromol), were assessed 2 weeks after treatment. No difference in melphalan content of tumor/liver tissue or antitumor effect was observed between rats treated with 5- and 20-min HAI. Hepatotoxicity was strongly affected by perfusion duration/concentration, however. Rats treated with 5-min HAI weighed significantly less, and liver toxicity parameters were significantly increased compared with those of all other groups; eight of nine rats showed severe cholangiofibrosis. Body weights and liver toxicity parameters of the rats treated with 20-min HAI were not statistically different from the control group. In conclusion, duration of HAI with 4.4 micromol of fixed dose melphalan did not affect tumor uptake and antitumor effect, but the resulting increase in melphalan concentration had major impact on hepatobiliary toxicity. Therefore, in a clinical setting, caution should be taken when infusion duration and concentration of melphalan are changed.

Increasing the drug concentration in tumors may produce massive tumoral response. By using a variety of hepatic vascular isolation techniques, high concentrations of chemotherapeutic drugs may be achieved in the hepatic vascular bed.. Complete percutaneous isolated hepatic perfusion (IHP) is feasible and safe.. Case series.. The hepatobiliary unit of a university hospital.. Ten patients with irresectable and chemoresistant hepatic tumors were eligible for study participation; 4 patients with hepatic metastases of breast cancer, gastric cancer, colorectal cancer, and cholangiocarcinoma were included.. Patients received 3 successive courses of chemotherapy by IHP. The first course was given at laparotomy, and the next 2 courses were given percutaneously. The interval between courses was 3 to 6 weeks. Each course involved IHP of the liver for 15 to 30 minutes, without oxygenation, with 1 to 3 boluses of melphalan (15 mg).. Morbidity and mortality.. Ten IHPs were performed (4 at laparotomy and 6 percutaneously). Concentrations of melphalan in the extracorporeal circulation were 10 times higher than those in the systemic circulation. Percutaneous IHPs had more leakage than those at laparotomy. However, hepatotoxicity was minimized. One patient experienced hepatic artery thrombosis, and 3 had severe neutropenia. Minor complications included ascites and pleural effusion. No deaths were observed 2 months after the last IHP. One partial response was observed (hepatic metastases of breast cancer).. Percutaneous IHP for intensive chemotherapy is less aggressive and less hepatotoxic than IHP at laparotomy and may be iterative.

Liver plasmacytoma is a very rare form of solitary plasmacytoma, in fact the presence of plasma cells in the liver is generally associated with a more aggressive form of multiple myeloma. We report an unusual case of liver plasmacytoma without systemic disease, diagnosed by percutaneous needle biopsy of the hepatic lesion, treated with six courses of melphalan and prednisone who achieved a good clinical remission after five years of follow-up.

Many patients with colorectal carcinoma develop unresectable metastases confined to the liver that remain the life-limiting component of disease despite best available systemic or regional chemotherapy. In the current study, the authors present their results using vascular isolation and perfusion of the liver for individuals with progressive, unresectable liver metastases from colorectal carcinoma that were refractory to both previous systemic and regional chemotherapy.. Seven patients with refractory, progressive, unresectable colorectal carcinoma metastases confined to the liver underwent a 60-minute hyperthermic (39-40 degrees C) isolated hepatic perfusion (IHP) and were followed for toxicity, response, and survival.. There was no surgical- or treatment-related mortality; all patients experienced transient Grade 3-4 (according to National Cancer Institute common toxicity criteria) hepatic toxicity. At a median potential follow-up of 16 months, the overall objective radiographic response rate (all partial responses) was 71% (5 of 7 assessable patients). It is interesting to note that two patients who were treated with tumor necrosis factor (TNF) alone demonstrated no response to therapy compared with all five patients who were treated with melphalan and TNF (three patients) or melphalan alone (two patients). For the 5 patients who responded to treatment, the median duration of response was 10 months (range, 10-13 months) and in all 7 patients the mean overall survival was 19.7 months (range, 2-33 months), including 5 months and 7.5 months, respectively, for the 2 patients treated with TNF alone.. The results of the current study demonstrate that IHP using melphalan with or without TNF has significant antitumor activity in this patient population. IHP deserves continued clinical evaluation as a therapeutic modality for patients with unresectable colorectal carcinoma metastases to the liver.

Isolated hepatic perfusion (IHP) with melphalan is used for patients with nonresectable metastases confined to the liver. To improve the efficacy of IHP and to reduce the toxicity to the liver, reversion (retrograde perfusion) of the bloodstream through the liver in a rat model was studied. For liver tumor induction male WAG/Rij rats were inoculated with CC531 cells, a colorectal tumor cell line. After 11 to 12 days the tumor-bearing rat livers were perfused by single-pass perfusion through either the portal (orthograde) or caval vein (retrograde) for different time periods. During perfusion melphalan (160 Schultze) was infused in the hepatic artery. Melphalan concentrations were measured by high-performance liquid chromatography. A rapid extraction of melphalan by the liver occurred in the first 5 min, reaching steady state after 10 to 20 min for both perfusion directions. The melphalan concentration of the outflow perfusate was significantly higher in the retrograde perfusion compared with the orthograde perfusion. The melphalan content of the tumor tissue was unaffected by perfusion direction at any time point. To the contrary, the melphalan uptake in liver tissue was strongly influenced: the melphalan content after 40-min retrograde perfusion was 12% of that after orthograde perfusion. The average tumor/liver concentration ratio was 6 for orthograde perfusion and 30 for retrograde perfusion. In conclusion, retrograde IHP with continuous melphalan infusion in the hepatic artery provides a high tumor uptake of melphalan with potentially reduced liver toxicity compared with orthograde IHP.

We compared two prospective trials of intra-arterial cytokine/chemotherapeutic infusion plus chemoembolization in the treatment of inoperable colorectal liver metastases.. One hundred and three patients with disseminated inoperable colorectal liver metastases received intra-arterial chemotherapy with 5-FU and granulocyte-macrophage colony-stimulating factor (GM-CSF) plus chemoembolization via an angiographically positioned hepatic artery catheter. Two different regimens were used in two consecutive studies. Group A: short-term i.a. infusion of 550 mg/m(2)5-FU (days 1-4) plus 80 microg/m(2)GM-CSF (day 1+2) combined with chemoembolization with 25 mg/m(2)melphalan plus Lipiodol and Gelfoam (day 5). Group B: continuous circadian intra-arterially administered 1400 mg/m(2)5-FU infusion plus 60 mg/m(2)i.v. leucovorin and 80 microg/m(2)GM-CSF (day 1+2) combined with chemoembolization with 25 mg/m(2)melphalan plus Lipiodol and Gelfoam (day 3).. One hundred and three patients (62 male/41 female) with a median age of 59.9 and a median Karnofsky index of 88.5 were treated with 447 cycles of immuno-chemoembolization (group A 299, group B 148 cycles). Fifty-seven percent of these patients had received prior systemic chemotherapy. Side-effects were seen in all patients, mainly upper abdominal pain lasting 1-4 days and grade 1 or 2 vomiting. Systemic side-effects were mild and transient with a very low rate of leukopenia. Using World Health Organization response criteria, the following responses could be demonstrated: group A: CR 2.7%, PR 32.4%, MR 21.6%, SD 12.7%, NR 16.2%; group B: CR 1.0%, PR 42.4%, MR 24.2%, SD 18.2%, NR 12.1%. Time to progression was 7 as compared to 8 months. Median survival was 17 months in group A, whereas it has not been reached after 28 months (P=0.0095) in group B. There was no statistically significant difference between chemo-naive patients and patients who had received prior systemic therapy.. Immuno-chemoembolization combined with 2-day circadian administration of 5-FU is an effective tool in the treatment of disseminated colorectal liver metastases. This regimen is also effective as second-line treatment.

Isolated organ perfusion of the liver or extremity with tumor necrosis factor (TNF) and melphalan results in regression of bulky tumors in the majority of patients. The efficacy of TNF in this setting is not known, although data suggest that it may exert antitumor effects primarily on tumor-associated neovasculature. We studied the effects of TNF on capillary leak in liver and tumor tissue during isolated hepatic perfusion (IHP) with melphalan. Twenty-seven patients with unresectable cancer confined to the liver underwent a 60-min hyperthermic IHP using 1.5 mg/kg melphalan alone (n = 7) or with 1.0 mg of TNF (n = 20). Complete vascular isolation was confirmed in all patients using an intraoperative leak monitoring I-131 radiolabeled albumin technique. Samples of tumor and liver were collected just prior to and immediately after IHP. There was no difference in I-131 radiolabeled cpm/g of tissue (cpm) in liver versus tumor at baseline (P2 = 0.44). After IHP, I-131 albumin cpm were higher in tumor versus liver (10,999 +/- 1,976 versus 3,821 +/- 780, respectively; P2 < 0.005). However, I-131 albumin cpm in tumor were not effected by TNF (11,636 +/- 2,518 with TNF versus 9,180 +/- 2,674 without TNF; P2 = 0.59). TNF did not affect melphalan concentrations in tumor (1,883 +/- 540 ng/g versus 1,854 +/- 861 ng/g without TNF; P2 = 0.9). Capillary leak, as reflected by diffusion of I-131 radiolabeled albumin into the interstitial space, is comparable in liver and tumor before IHP but is significantly higher in tumor after IHP. The increased diffusion in the capillary tumor bed must occur through TNF-independent mechanisms such as intrinsic features of tumor neovasculature, hyperthermia, or other unrecognized perfusion-related factors. These data indicate that TNF must continue to be critically evaluated in clinical trials before it is routinely used with melphalan in isolated organ perfusion.

In this study we determined the level of tumour necrosis factor alpha (TNF-alpha) in liver and tumour tissue samples obtained from patients with colorectal metastases confined to the liver, who were treated with isolated liver perfusion with TNF-alpha and melphalan. We adapted a standard enzyme-linked immunosorbent assay kit for the quantification of TNF-alpha in serum to measure the amount of this cytokine in solid tissue. For this purpose, we developed a buffer that lysed the tissues without affecting the TNF-alpha present. The minimum detection level was about 2 pg of TNF-alpha per mg tissue. Using this technique, we found a significant increase in the TNF-alpha level after perfusion in the liver tissue of all evaluable patients, which may explain the transient liver toxicity we observed in all patients. In tumour tissue, a significant TNF-alpha increase was observed in one out of five patients. The level of TNF-alpha in all liver tissue samples and some of the tumours after treatment by isolated liver perfusion was much higher than the peak serum concentrations obtained after systemic administration of the maximum tolerated dose of TNF-alpha. Furthermore, we demonstrated that the level of TNF-alpha in the liver tissue samples was about seven to eight times higher than in tumour tissue. We concluded that regional liver treatment resulted in a relatively high local level of TNF-alpha, but also that this cytokine did not preferentially accumulate in tumour tissue.

Regional isolated perfusion using tumor necrosis factor (TNF) shows significant promise for treatment of cancer which is limited to limbs or organs. The high toxicity of TNF requires very sensitive real time monitoring of leakage in order to avoid serious patient complications. Human serum albumin labeled with iodine-131 is used with an externally mounted and collimated NaI(Tl) detector to track the leakage of blood from the isolated perfusion blood circuit into the general systemic vascular space. Blood activity levels measured using the monitor demonstrated a very good correlation with blood serum samples taken concurrently with external monitoring. External monitoring can reduce the risks of perfusion leakage intraoperatively with the precision necessary to safely perform isolated perfusion using TNF.

A 44-year-old woman had small cell carcinoma of the esophagus complicated by liver and lymph node metastases. She was treated with aggressive combination chemotherapy, followed by autologous bone marrow transplantation and adjuvant radiation therapy. (The authors believe this to be the first use of autologous bone marrow transplantation for treatment of this condition.) This regimen resulted in apparent complete regression of the disease as documented by computed tomography and endoscopic study. Three years later, she again experienced general malaise and was found to have extensive recurrent disease in the lung, bone, and liver. Her condition deteriorated rapidly, and she died within 1 month. A review of the literature reveals that this patient survived longer than any others who have had this rare but aggressive tumor. The authors suggest that this form of therapy should be considered for future patients.

Eight patients with advanced liver malignancy undergoing isolated hyperthermic liver perfusion with melphalan and cisplatin were studied with regard to complement activation and formation of anaphylatoxins (C3a and C5a) and terminal C5b-9 complement complexes (TCCs). Blood samples for complement variables (C1-INH, C3, C4, C5, C3a, C5a and TCCs) were taken before surgery, 1 min before the start of perfusion, 1, 2 and 3 h after the start of perfusion, and 24 h after operation. Samples were drawn from the perfusate 1 h after the start of perfusion. Activation of complement was observed during perfusion. Raised plasma concentrations of C3a and TCCs were recorded and high levels of C3a and TCCs were found in the perfusate. In vitro tests indicated that melphalan and cisplatin may activate complement. This activation occurred at 37 and 42 degrees C but was more pronounced at 42 degrees C.

Regional chemotherapy allows further exploitation of the steep dose response curve of most chemotherapeutic agents, while systemic toxicity remains tolerable. We investigated the difference in maximally tolerated dose, pharmacokinetics and antitumour effect comparing administration of melphalan as a bolus in isolated liver perfusion (ILP) or via hepatic artery infusion (HAI). For these in vivo studies an experimental model for liver metastases in male WAG/Ola rats is obtained by subcapsular inoculation of CC531 rat colon carcinoma cells. In this system, ILP allowed administration of a two times higher dose than HAI (12 mg kg-1 vs 6 mg kg-1). In both treatment modalities systemic toxicity (leukopenia) was dose limiting. No hepatic toxicity was observed. Bolus administration of the maximally tolerated doses of melphalan in HAI (6 mg kg-1) and ILP (12 mg kg-1) resulted in four times higher concentrations in both liver and tumour tissue of the ILP treated rats. However, the ratio of mean drug concentration in liver vs tumour tissue appeared to be 1.5 times that found for HAI. In the range of the in tumour tissue measured melphalan concentrations the CC531 cells showed a steep dose response relationship in vitro. Whereas HAI resulted in significant tumour growth delay, complete remissions were observed in 90% of the rats treated with ILP. This study shows that with 12 mg kg-1 melphalan in ILP highly effective drug concentrations are achieved in CC531 tumour tissue; although the melphalan concentration in liver tissue shows an even higher increase than in tumour tissue, hepatic toxicity is negligible in this dose range.(ABSTRACT TRUNCATED AT 250 WORDS)

A 54-year-old man was admitted to our hospital for precise examination of pancytopenia in October 1988. He had been cut off his left femur and irradiated because of osteosarcoma in 1954. After 30 years, he was diagnosed as Waldenström's macroglobulinemia. Melphalan had been given 2 mg daily for 19 months until August 1988, when it was discontinued due to pancytopenia. Peripheral blood showed Hb 6.6 g/dl, platelet 40 x 10(3)/microliters, and WBC 2000/microliters with 33% blasts. Bone marrow showed normocellularity with 36% blasts. Although blasts were negative for peroxidase staining, surface marker analysis revealed myeloid (CD 13, CD 33) phenotypes. Chromosome analysis showed 45, XY, -7, inv (3). A CT scan of the liver showed a mass, 10 by 10 cm, compatible with hepatocellular carcinoma. He was treated with very low dose Ara-C without noticeable effect. Hepatic tumor gradually enlarged, and he died of hepatic failure. This is a rare case of quadruplicate malignancies. The chromosomal abnormality suggests that AML was secondary leukemia which might be associated with immunosuppression due to macroglobulinemia and/or melphalan therapy.

Nineteen patients with metastatic malignant melanoma were treated with 20 courses of high-dose combination alkylating agent chemotherapy and autologous bone marrow support. All 20 treatment courses were evaluable for toxic reactions and 17 of 20 courses were assessable for response. Twelve of the 20 courses were given at the phase 2 dose per square meter of cyclophosphamide (5.625 g), cisplatin (165 mg), and carmustine (600 mg). Marrow reconstitution occurred with a median time to recovery of 21 and 24 days for more than 500 neutrophils and more than 20,000 platelets, respectively. The overall response rate was 65%, with one patient achieving a complete response with chemotherapy alone. Ten additional patients achieved partial responses following chemotherapy, of which three were subsequently rendered disease free by surgical resection of single areas of residual tumor. Two of these patients are alive and disease free more than 22 months following chemotherapy and one remains relapse free. The median survival for responding patients was 15.2 months and 8.6 months for the entire group.

The inoculation of a mixture of drugs and guinea pig hepatoma cells (line-10) induced tumor-specific immunity in about 20% of guinea pigs. When guinea pigs with established intradermal tumors were given various drugs ip, no cures were observed; in contrast, multiple intralesional injections of actinomycin D, 1,3-bis(2-chlorethyl)-1-nitrosourea, adriamycin, mitomycin C, and melphalan were effective in curing animals of their intradermal tumors at a time when there were tumor cells in the draining lymph nodes; dimethyl-triazenoimidazole carboxamide, methotrexate, 5-fluorouracil, and 6-mercaptopurine were not effective. More than 80% of the cured animals were immune to rechallenge with 10(6) line-10 tumor cells.

Immunological function was studied in 48 patients before, during and after cancer treatment, using cutaneous tests, spontaneous rosettes test and the PHA and PWM lymphocyte stimulation tests. Chemotherapeutic drugs were used individually or in combination for 5 days a month and were preceeded by a cellular synchronization using Vincristine (1 mg/m2/day). When treatment was discontinued, we observed in 30 patients increased rates of spontaneous rosettes and of thymidine uptake. We noticed in several cases that the cutaneous tests became positive even if they were negative before and during treatment. The I.O.P. appeared 5 days after chemotherapy was discontinued and lasted 8 to 12 days. The topography of the neoplasm had no influence on the I.O.P. Failure to manifest I.O.P. is not indicative of a negative response of the tumor to chemotherapy (9 positive responses to chemotherapy out of 18 patients without I.O.P.) But the I.O.P. was a fairly constant feature in patients with positive response to chemotherapy and with favorable prognosis (28/30).
