[Prospective randomized trial comparing modified FAM (5-fluorouracil (5-FU) + adriamycin + mitomycin C) versus 5-FU alone for the treatment of non-resectable pancreatic and biliary tract carcinomas (the 1st trial in non-resectable patients). Study Group of Surgical Adjuvant Therapy for Carcinomas of the Pancreas and Biliary Tract].

The modified FAM (5-fluorouracil (5-FU) + adriamycin (ADR) + mitomycin C (MMC)) therapy (FAM group) was compared with 5-FU mono-therapy (F group) by multi-institutional randomized trial in the patients with cancer of the pancreas or the biliary tract who underwent non-resection. The patients in FAM group received 6 mg/m2 of i.v. MMC during operation, 310 mg/m2 of i.v. 5-FU for 5 days in the 1st and 3rd postoperative weeks and 12 mg/m2 of i.v. ADR in the 2nd postoperative week. Those in F group received only 5-FU course in the administration schedule of FAM group. Among the cases which completed respective whole administration schedules. 35 cases in FAM group and 36 in F group, better effect than partial response (PR) was observed in neither groups, and there was no significant difference between groups with respect to overall/each disease survival duration, progression-suppressed duration and clinical effect. Primary adverse effects were alimentary symptoms and hepatic dysfunction, neither of which was serious, and there was no difference between groups except that hair loss was observed in more cases in FAM group (p less than 0.05). Results in FAM group did not statistically surpass those in F group, but a tendency was observed that FAM group was better than F group in terms of survival duration and clinical effect for cancer of the gall-bladder.
