Forty-four previously untreated patients with advanced inoperable and/or disseminated gastric carcinoma were given an i.v. combination (FAM2) chemotherapy of 5-fluorouracil, 400 mg/m2 on days 1, 2 and 3, and 21, 22 and 23; adriamycin, 40 mg/m2 on days 2 and 22; and mitomycin C, 10 mg/m2 on day 1, with a recycle on day 42 (1 cycle = 41 days). Forty patients have completed 2 cycles and are evaluable (median number of cycles 5; range 3 to 8): 26 of these achieved a partial remission, with a response rate of 65%; 4 (10%) gained a stable situation for 3 to 6 months, and 10 (25%) showed progression of disease. Median duration of partial remissions was 10 months, and median survival was 15 months for responders and 5 months for nonresponders. A fall in WBC (less than 2500/microliter) occurred in 7% and of platelets (less than 80,000/microliter) in 4.5%. Total alopecia occurred in 20 of 40 patients and nausea and or weakness were common findings. No drug-related infection, bleeding or death was observed. Patients with advanced gastric carcinoma can derive useful palliation from FAM2 chemotherapy.
