EPIRUBICIN-SEQUENTIAL METHOTREXATE-5-FLUOROURACIL-LEUCOVORIN TREATMENT IN ADVANCED CANCER OF THE EXTRAHEPATIC BILIARY SYSTEM - A PHASE-II STUDY

A combination chemotherapy was used to treat patients with advanced cancer of the extrahepatic biliary system not amenable to surgical resection. Between February 1985 and April 1992, 22 consecutive patients entered into the study; 17 (11 with extrahepatic bile duct cancer and 6 with gallbladder cancer) were evaluable for response and toxicity. The treatment schedule was as follows: epirubicin 20 mg/m2 given as a bolus, followed by methotrexate 150 mg/m2 as a 30-minute infusion, 1 hour later 5-fluorouracil 600 mg/m2 as a 30-minute infusion. Leucovorin rescue (15 mg orally every 6 hours for eight doses) was started 24 hours after methotrexate. This course was administered once a week in 3 successive weeks followed by a 2 to 3 weeks rest period. A total of 174 courses was given. No objective tumor regression was observed. This regimen was well tolerated, the main toxicity being gastrointestinal. The median survival time for the 17 evaluable patients was 9 months.
