Fotemustine (S 10036) in the intra-arterial treatment of liver metastasis from malignant melanoma. A phase II Study.
Fotemustine is a new nitrosourea which has shown some efficacy on disseminated malignant melanoma (DMM) (24.2% response rate (RR) among 153 patients in a Phase II trial) but little activity on hepatic metastasis (8.8% RR). In order to improve those poor results, hepatic intra-arterial infusion (HIAI) of fotemustine was performed. After two years, thirteen patients, all in good general condition, were evaluable. Seven were pretreated and six had extrahepatic metastasis on entry into the study. All patients had a surgically implanted intra-arterial catheter. The induction cycle consisted of 100 mg/m2/week for 3-4 weeks, followed by 5 weeks rest and maintenance therapy of 100 mg/m2 every 3 weeks for stabilized or responding patients. Two complete responses (CR) (72+ and 145+ weeks) and six partial responses (PR) (7-18.5 weeks) were observed. The hepatic RR reached 61.5%. A RR of 42.8% was registered on preexisting EHM (one CR and one PR on cerebral lesions). Nevertheless, this treatment is limited by the high progression rate of 46.1% in extrahepatic disease. Toxicity was mainly hematologic (grade III-IV), comprising 36% neutropenia and 15% thrombopenia. Hepatic intra-arterial infusion of fotemustine is efficient therapy for liver metastases of DMM, but combination schedules (IV + HIA) are warranted.
