N2 - BACKGROUND. Single-agent chemotherapy with dacarbazine continues to be the standard of care for the treatment of metastatic melanoma. However, there is a large population of patients who have failed first-line therapy and might benefit from additional treatment. In the current study, the authors evaluated the antitumor effects and toxicity of vinorelbine therapy in patients who had failed one prior systemic therapy. METHODS. Patients were required to have a histologic diagnosis of melanoma and be of Stage IV with measurable disease, a Southwest Oncology Group (SWOG) performance status (PS) of 0-2, no evidence of brain metastases, and adequate bone marrow and liver function. Treatment was comprised of vinorelbine given at a dose of 30 mg/m2/week by intravenous bolus. RESULTS. Twenty-four patients were registered to the study, 3 of whom were determined to be ineligible. The 21 eligible patients had a median age of 58 years with a SWOG PS of 0 in 7 patients, 1 in 13 patients, and 2 in 1 patient. There were no complete or partial responses observed, for a response rate of 0 of the 21 patients studied (95% confidence interval [95% CI], 0-16%); the study closed after the first stage of accrual. The estimated median progression-free survival was 2 months (95% CI, 1.5-3.3 months) and the estimated median overall survival was 6 months (95% CI, 3.7-8.3 months). There was one death due to febrile neutropenia reported, with six patients experiencing one or more Grade 4 toxicities, including neutropenia/granulocytopenia, leukopenia, dyspnea, and fatigue. CONCLUSIONS. Despite impressive preclinical activity against melanoma, vinorelbine does not appear to have enough clinical activity to be of interest in previously treated patients with disseminated melanoma. The progression-free and overall survival results noted in previously treated patients in the current study were similar to results reported in prior SWOG Phase II trials in untreated patients. The group of previously treated patients may be used to evaluate new agents for the treatment of disseminated melanoma.
