Isolated Hepatic Perfusion With Melphalan in Treating Patients With Primary Unresectable Liver Cancer or Liver Metastases

ABSTRACT: RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Giving drugs in different ways may kill more tumor cells. PURPOSE: This phase II trial is studying how well isolated hepatic perfusion with melphalan works in treating patients with primary unresectable liver cancer or liver metastases.

Hepatic Arterial Infusion of Melphalan With Hepatic Perfusion in Treating Patients With Unresectable Liver Cancer

Project description:RATIONALE: Hepatic arterial infusion uses a catheter to deliver anticancer substances directly into the liver. Drugs used in chemotherapy, such as melphalan, work in different ways to stop tumor cells from dividing so they stop growing or die. Giving drugs in different ways may kill more tumor cells. PURPOSE: This phase II trial is studying how well giving an hepatic arterial infusion of melphalan together with hepatic perfusion works in treating patients with unresectable liver cancer.

Project description:RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining more than one drug and giving them in different ways may kill more tumor cells. It is not yet known which chemotherapy regimen is most effective for colorectal cancer that has spread to the liver. PURPOSE: Randomized phase III trial to compare the effectiveness of combination chemotherapy with or without isolated hepatic perfusion with melphalan in treating patients who have colorectal cancer that has spread to the liver.

A Phase I Study of Isolated Hepatic Perfusion With Escalating Dose Melphalan Followed by Postoperative Hepatic Arterial Floxuridine and Leucovorin for Metastatic Unresectable Colorectal Cancers of the Liver

Project description:Patients with unresectable metastatic colorectal cancer confined to the liver will undergo a 1 hour hyperthermic isolated hepatic perfusion (IHP) with escalating dose melphalan. Postoperatively, patients will be treated with hepatic arterial infusion of floxuridine (FUDR), 0.2 mg/kg/day and leucovorin (LV), 15 mg/M2/day as a 2-week continuous infusion regimen. Hepatic and systemic toxicity, response to treatment, duration of response, and survival will be followed.

Isolated hepatic perfusion with 200 mg melphalan for advanced noncolorectal liver metastases.

Project description:PURPOSE: 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. PATIENTS AND METHODS: 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. RESULTS: 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. CONCLUSION: 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.

Metabolic Changes Contribute to Melphalan Resistance in Multiple Myeloma

Project description:Multiple myeloma is an incurable hematological malignancy that impacts tens of thousands of people every year in the U.S. Treatment for eligible patients includes three stages: induction, consolidation with stem cell rescue, and maintenance. High dose therapy with the DNA alkylating agent, melphalan, remains the primary drug for consolidation therapy in conjunction with autologous stem cell transplant. As a result, melphalan resistance remains a clinical challenge. Here, we use proteometabolomics to examine mechanisms of melphalan resistance in two cell line models. Drug metabolism, steady-state metabolomics, activity-based protein profiling (ABPP), acute treatment metabolomics, and immunoblotting analyses have allowed us to further elucidate metabolic processes contributing to melphalan resistance. Proteometabolomics data indicate that both drug resistant cells have higher levels of pentose phosphate pathway metabolites than their naïve counterparts. Interestingly, we also observed cell line specific changes in purine, pyrimidine and glutathione metabolism that are linked to the differences in steady state metabolism of naïve cells and highlight the heterogeneity of melphalan resistance in these models. Because of the diversity of metabolic changes, our data suggest that omics approaches will be needed to fully examine melphalan resistance in patient specimens and define personalized strategies to optimize the delivery of this therapy.

In vivo study of ADH-1 in combination with melphalan for treatment of melanoma

Project description:To identify patterns of change in gene expression that correlated with drug treatment (saline control, ADH-1 alone, melphalan alone and ADH-1 plus melphalan) in our animal model of regional therapy for extremity melanoma we evaluated gene expression using microarray genechips and a Pearson correlation analysis. Genes were ranked according to the degree to which expression correlated with systemic ADH-1 treatment alone or in combination with regional melphalan. Tissue samples were harvested at 4, 24 and 48 hours after treatment with melphalan. Specific cellular pathways associated with drug treatment were identified using gene set enrichment analysis (GSEA). Keywords: time course; chemotherapy; melanoma; melphalan; N-cadherin; ADH-1

Melphalan-treated human retinal endothelial cells

Project description:Super-selective intra-ophthalmic artery chemotherapy (SSIOAC) is an organ-specific drug-delivery strategy to treat retinoblastoma, the most common primary ocular malignancy in children. Unfortunately, recent clinical reports associate adverse vascular toxicities with SSIOAC using melphalan, the most commonly used chemotherapeutic. To explore the reason for the unexpected vascular toxicities, we have developed in vitro studies with human retinal endothelial cells to test the effects of the chemotherapeutics and a non-human primate model to monitor the SSIOAC treatment in real-time and post-treatment. Melphalan and carboplatin (another chemotherapeutic used to treat retinoblastoma via SSIOAC) triggered migration, proliferation, and apoptosis when used to treat human retinal endothelial cells. Melphalan was associated with increased adhesion of leukocytes to human retinal endothelial cells, and tended to increase with increased cell expression of adhesion proteins (ICAM-1) and soluble chemotactic factors (IL-8). Histopathology post-SSIOAC indicated vessel wall sloughing, leukostasis, and vessel occlusion. We have established an in vitro human cell culture model and a non-human primate model to evaluate strategies designed to obviate vascular side effects, and optimize the efficacy of SSIAOC and the drug preparations used in SSIOAC. 4 non-treated (MNT) vs. 4 melphalan-treated primary human retinal endothelial cells (RECs).
