Between March, 1983 and June, 1986, 64 patients with metastatic or recurrent colorectal cancer were treated with a combination chemotherapy consisting of 5-fluorouracil (5-FU), 1,000 mg/㎡ iv continuous infusion over 12 hours on day 1-5; mitomycin-C, 10 mg/㎡ iv on day 1; cycled every 4 weeks. Among 46 patients with measurable lesions, none achieved complete remission and 5 (11%) achieved partial remissions. The median duration of remission was 31 weeks. Overall median survival was 49 weeks for all patients; 65 weeks for patients with remission; 51 weeks for those with stable disease; and 31 weeks for those with progressive disease. Greater response rates were observed in patient groups with age over 50, performance status 0-1, no previous history of chemotherapy, initial CEA level less than 10 ng/ml, or metastatic sites of lymph node, than in respective comparative patient groups. But, these differences did not achieved statistical significance. Toxicity was common, but generally mild to moderate and rapidly reversible.
