BACKGROUND The aim of this study was to compare the long-term safety and efficacy of oral busulfan 12 mg/kg plus melphalan 140 mg/m(2) and melphalan 200 mg/m(2) as conditioning regimens for autologous stem cell transplantation in newly diagnosed patients with multiple myeloma in the GEM2000 study. DESIGN AND METHODS The first 225 patients received oral busulfan 12 mg/kg plus melphalan 140 mg/...
PURPOSE The onset of drug resistance is a major cause of treatment failure in multiple myeloma. Although increasing evidence is defining the role of miRNAs in mediating drug resistance, their potential activity as drug-sensitizing agents has not yet been investigated in multiple myeloma. EXPERIMENTAL DESIGN Here we studied the potential utility of miR-221/222 inhibition in sensitizing refract...
Peptichemio (PTC), a mixture of six oligopeptides all containing m-L-sarcolysin, has previously shown impressive results in clinical trials. The tripeptide P2 (L-prolyl-m-L-sarcolysyl-p-L-fluorophenylalanine ethyl ester) has been suggested as the main contributor to PTC activity. In contrast to its analogue melphalan, m-L-sarcolysin never reached clinical use. To allow a direct comparison, the ...
Melphalan resistance developed previously in a human melanoma cell line (MM253) could not be further increased. Cross-resistance was found to nitrogen mustard but not to ultraviolet light radiation. A clone of MM253 had the same drug sensitivity and heterogeneous chromosome complements as did the parent culture. The melphalan-resistant cells (MM253-12M) had 2.6-fold the D0, 1.5-fold the size, 1...
BACKGROUND This study aims to determine the synergistic effects of the chemotherapeutic drug melphalan and the phytoconstituents extracted from Pinus kesiya Royle ex Gordon (Simaosong) in human cancer cells. METHODS P. kesiya twigs extracted from 50 % ethanol-water were evaluated alone (6-500 µg/mL) and in combination with melphalan (0.75-15 µg/mL). The cytotoxic effects of single extract or ...
Melphalan transport, glutathione levels, and glutathione-S-transferase activity were measured in two continuous human medulloblastoma cell lines and transplantable xenografts in athymic nude mice, TE-671 and Daoy. In vitro mean glutathione levels were 10.06 nmol/10(6) cells in TE-671 and 2.96 nmol/10(6) cells in Daoy. In vitro mean glutathione-S-transferase values were 91.52 nmol/min/mg protein...
Cytoreductive surgery (CRS) with hyperthermic intraperitoneal chemotherapy (HIPEC) is a treatment option for peritoneal metastases. The optimal agents for HIPEC have not been established. Melphalan is a drug with broad activity and a favorable profile for intraperitoneal application. The purpose of this study is to review our experience using melphalan for HIPEC. Pharmacologic data was obtained...
Based on previous work demonstrating the activity of cyclophosphamide and melphalan in a series of human medulloblastoma and rhabdomyosarcoma cell lines and transplantable xenografts, investigations were conducted to define the effects of combining cyclophosphamide or melphalan with VP-16. These studies demonstrated a synergistic interaction between cyclophosphamide and VP-16 and melphalan and ...
Median survival of patients with AL amyloidosis with clinically significant cardiac involvement is 5 months when treated with cyclic melphalan and prednisone. We investigated a regimen of continuous oral melphalan as a single agent for patients with cardiac amyloidosis who were unable to tolerate prednisone or more aggressive chemotherapy. Thirty patients with amyloid cardiomyopathy were treate...
Isolated limb perfusion (ILP) with melphalan and tumor necrosis factor (TNF)-α is used to treat bulky, locally advanced melanoma and sarcoma. However, TNF toxicity suggests a need for better-tolerated drugs. Cilengitide (EMD 121974), a novel cyclic inhibitor of alpha-V integrins, has both anti-angiogenic and direct anti-tumor effects and is a possible alternative to TNF in ILP. In this study, r...
