Advanced colorectal cancer treated with combined 5-fluorouracil and folinic acid: the experience within a surgical department.

Thirty-seven patients with advanced colorectal cancer were treated with fluorouracil (5-FU) and folinic acid (FA) (Jan 1990-Dec 1992). Clinical assessment and administration of chemotherapy was incorporated as part of the daily work load of a busy general surgical unit. Records were available for all 37 patients and showed that 13 patients (Treatment failures, Group B) failed to receive more than 3 monthly cycles of treatment, while the remaining 24 received 6 or greater cycles (Treatment completed, Group A). There was no survival advantage demonstrated for the complete study cohort (n = 37) when compared to an historical group (n = 1038) of untreated patients. Median survival in Group A (14.2 months) was significantly greater (chi-squared, P < 0.0001) than survival in Group B (6.7 months). Toxicity was common with 43% experiencing mouth ulcers or stomatitis (13% severe). Three per cent had dose-limiting diarrhoea and myelotoxicity was minimal. There were six partial responses and 16 patients had no change in their disease status while on treatment. Current regimen of 5-FU/FA are well-tolerated with low toxicity but show no survival advantage for advanced colorectal cancer. However, these regimens may be administered within the confines of general surgical practice.
