Abstract: |
The combination of cisplatin plus dacarbazine (DTIC) is active in metastatic melanoma with response rates reported between 10% and 55%. To optimize this regimen, a Phase II study was conducted employing a dose intensity of cisplatin higher than previously reported. Twenty‐two patients were treated. Eight patients received cisplatin 100 mg/m2 on days 1 and 8 combined with DTIC 300 mg/m2 on days 1, 2, 8, and 9 (regimen A). Because of excessive toxicity, the protocol was modified so that cisplatin was given at 50 mg/m2 per day and DTIC 350 mg/m2 per day on days 1 through 3 (regimen B). The overall response rate was 32% and consisted of four partial and three complete responses (CR). The median duration of response was 6 months. Two of the CR remain in sustained, unmaintained remission in excess of 1.5 years. All seven patients that responded were treated on regimen B. High‐dose cisplatin plus DTIC on a 3‐day schedule represents an effective, well‐tolerated therapy for metastatic melanoma. Copyright © 1991 American Cancer Society |
