Combination chemotherapy of cisplatin and 5-FU in advanced colorectal carcinoma.

Thirty-two patients with advanced colorectal carcinoma were treated with cisplatin (100 mg/m2) by infusion over 24 hours on Day 1 and 5-FU (1000 mg/m2/day) by infusion over 24 hours on Days 2-6 every 28 days. Ten of the 32 patients had received prior chemotherapy consisting of either 5-FU alone or 5-FU combination regimens. Objective response was observed in 13 patients (two complete and 11 partial responses). Another 11 patients had stabilization of disease. The overall median survival time in this study was 9.53 months. Toxicity was generally mild and tolerable. The response rate found in this study indicated that continuous infusion of cisplatin-5-FU administered at this dose and schedule was moderately active in advanced colorectal carcinoma.
