ORR was higher in the fotemustine arm compared to the DTIC arm in first-line treatment of disseminated melanoma. A trend in favor of fotemustine in terms of overall survival and time to BM was evidenced.

A total of 42 patients with cerebral metastases of malignant melanoma were included in this study of the nitrosourea fotemustine. The treatment plan consisted of a l-h i.v. infusion of 100 mg/m2 fotemustine every week for 3-4 weeks, followed by a 4- to 5-week rest period. Responding or stabilised patients then received 100 mg/m2 fotemustine every 3 weeks. Among the 39 evaluable patients, 2 complete responses and 9 partial responses were documented, leading to an overall response rate of 28.2%. Most of the responses were obtained in previously untreated patients and/or those presenting with a single cerebral metastasis. Toxicity was mild and mainly hematological, especially in patients previously treated by polychemotherapeutic regimen. Our study confirms the activity of fotemustine in cerebral metastases of disseminated malignant melanoma.

A total of 70 patients presenting with a disseminated malignant melanoma were entered into a multicentric study of combination chemotherapy using dacarbazine and fotemustine. In all, 63 patients were evaluable, 31.8% of whom had previously received cytotoxic chemotherapy. The protocol consisted of induction treatment with a weekly infusion of 100 mg/m2 fotemustine on days 1 and 8 and a daily infusion of 250 mg/m2 dacarbazine on days 15/18 followed by a 4- to 5-week rest period. Responding and stabilized patients were given maintenance treatment comprising fotemustine (100 mg/m2, day 1) and dacarbazine (250 mg/m2, days 2/5) every 3 weeks. The response rate was 33.3% (9 complete responses (CRs) and 12 partial responses (PRs)) and was outstanding among pretreated patients (34.9%). Responses were also documented in cerebral (28.6%), visceral (23.1%) and nonvisceral (43.3%) metastatic sites. Toxicity was mainly hematologic (22.2%, grade III/IV leukopenia; 20.3%, grade III/IV thrombocytopenia) and was acceptable. These results are encouraging in terms of the antitumor activity against nonvisceral metastases (43.3%) and the percentage of CRs obtained (23.3%), and they confirm the activity of fotemustine in cerebral metastatic sites.
