A Randomized Phase III Trial of Hyperthermic Isolated Limb Perfusion With Melphalan, Tumor Necrosis Factor, and Interferon-Gamma in Patients With Locally Advanced Extremity Melanoma

DISEASE CHARACTERISTICS: Biopsy-proven Stage IIIA or IIIAB melanoma (M.D. Anderson staging system) of an extremity, as follows: Advanced local disease indicated by 2 or more satellite or in-transit metastases. Lower limb regional metastases must be distal to the apex of the femoral triangle except inguinal lymph node metastases. Upper limb regional metastases must be distal to the deltoid insertion except axillary lymph node metastases. No evidence of systemic disease outside the involved extremity. Recurrent disease subsequent to prior successful limb perfusion allowed. Bidimensional directly measurable dermal or subcutaneous lesion required. PRIOR/CONCURRENT THERAPY: No prior isolated limb perfusion. Biologic Therapy: At least 1 month since Biologic Therapy. At least 3 months since regional therapy of the extremity. Chemotherapy: At least 1 month since chemotherap.y At least 3 months since regional therapy of the extremity. Endocrine Therapy: Not specified. Radiotherapy: At least 1 month since radiotherapy. Surgery: Not specified. PATIENT CHARACTERISTICS: Age: 18 and over. Performance status: ECOG 0 or 1. Hematopoietic: Platelets greater than 150,000. Hepatic: Bilirubin less than 1.5 mg/dl; Coagulation profile normal. Renal: Creatinine less than 2.0 mg/dl. Cardiovascular: No evidence of peripheral vascular disease, e.g.: No history of claudication. OTHER: HIV negative. No pregnant or nursing women.
