Fotemustine plus dacarbazine for malignant melanoma.

119 patients with metastatic melanoma received fotemustine 100 mg/m2 on days 1 and 8 and dacarbazine 250 mg/m2 on days 15-18. After a 5-week rest, fotemustine 100 mg/m2 on day 1 and dacarbazine 250 mg/m2 on days 2-5 was given every 3-4 weeks. 12 complete responses (11.6%) and 16 partial responses were observed in 103 evaluable patients (response rate 27.2%). The median duration of response was 21.5+ weeks (8+ to 53+). The response rate was 26.3% in CNS, 18.2% in visceral sites and 37.5% in non-visceral sites. The toxicity was mainly haematological: grade III-IV leukopenia in 27.4% and thrombocytopenia in 23.4%. The response rate was lower than that in 63 patients previously reported. The present series had a higher median age (54 vs. 40 years) without any differences in other population variables. However, activity on CNS metastases and on non-visceral sites was confirmed. Haematological toxicity was about 50% lower than that with fotemustine alone. Hence, this is an active outpatient regimen for metastatic melanoma, especially against cerebral and non-visceral metastases.
