RESUMEN
The objective of this study was to investigate the efficacy of our treatment regimen in metastatic melanoma. Thirty patients entered the study after undergoing a thorough metastatic workup. Treatment protocol included carmustine (BCNU) (150 mg/m(2) IV, day 1) every 6 weeks, dacarbazine (DTIC) (220 mg/m(2) IV, days 1-3), and cisplatin (25 mg/m(2) IV, days 1-3) every 3 weeks, interferon A-2B (6 x 10(6) U/m daily s.c. on days 4-8 and 16-20) and tamoxifen 20 mg/day for 6 weeks. Among 29 evaluable patients, overall response was seen in 15 (52%) and complete response in 5 (17%) patients. Median duration of partial response was 4 months (range, 1-12 months); of complete response was 8 months (range, 2-14 months). Complete response continues in two patients with lung metastases. Median survival time was 8.7 months. Side effects were tolerable. Four (13%) patients developed neutropenic fever, and platelet transfusions were required in five (17%) patients. One patient died of neutropenic sepsis. Thrombocytopenia caused prolongation of the median interval between the first and second courses, and drug doses were reduced in the second course in 8 of 26 (31%) patients. Our chemoimmunohormonal regimen is efficient in metastatic malignant melanoma and can induce durable remission. Severe thrombocytopenia leads to a reduction of carmustine dose in a new protocol.
