Outcome of colorectal cancer

Abstract

The outcome of 454 patients who presented with colorectal carcinoma during a 16 year period is reviewed: 54 per cent were males, 58 per cent were aged more than 60 and 10 per cent had an emergency admission, 42 per cent of tumours occurred in the rectum. A curative resection was possible in 68 per cent. Postoperative mortality was 7 per cent. The overall crude 5-year survival was 41 per cent. The mortality from local recurrence was significantly higher in rectal (11.7 per cent) than in colonic cancer (8.8 per cent; P less than 0.01). The rate of recurrence and metastases was higher in patients with low rectal cancer than in patients with cancer of the middle and the upper rectum (P less than 0.01). Distant metastases were the cause of death in 94 per cent of the patients who had a Miles' operation for cancer of the middle rectum, whereas local recurrence was responsible for late mortality in 80 per cent of patients who underwent an anterior resection. No difference in 5-year survival was found in the restorative and in the excisional group.
