Abstract

Twenty-three patients with advanced colorectal cancer were treated with folinic acid (200 mg/m2/day 1-5IV bolus injection) and 5-fluorouracil (400 mg/m2/day 1-5 IV in 15 minutes) every 28 days. Only three patients were pretreated. Objective response was observed in 6 (30%) of 20 evaluable patients (three complete and three partial responses). The median duration of response was 9 months (range 5-15) and time to disease progression ranged from 2 to 12 months (median 6 months). Median survival was 21 months (range 12-23+) for responders. Another 6 (30%) patients had stabilization of disease. Toxicity was generally gastrointestinal (mucositis, diarrhea, nausea); moderate leukopenia was noted. The response rate found in this study indicates that folinic acid administered in high doses enhances the effectiveness of 5-FU administered concomitantly in colorectal cancer.
