Treatment of advanced colorectal adenocarcinoma with weekly high-dose l-leucovorin and 5-fluorouracil

Oncol Rep. 2002 Jan-Feb;9(1):93-6.

Abstract

We report the results of 5-fluorouracil (5-FU) combined with high-dose l-folinic acid (leucovorin) therapy for patients with advanced colorectal carcinoma. In each treatment course, the patients weekly received both 5-FU (600 mg/m2 by intravenous 15 min infusion) and l-folinic acid (250 mg/m2 by intravenous infusion over a period of 2 h). A total of six treatments were administered with a 14-day interval to the next course of six treatments. Forty-eight patients were evaluated for toxicity and 32 for response. The combined complete and partial response rate was 25% in 32 patients. Toxicity was within acceptable limits without grade 4 toxicity. Although the response rate was slightly lower than those reported in phase II trials in Japan, the result was satisfactory. This therapy can be the standard chemotherapy for colorectal cancer patients, even in Japan.
