Abstract
The results of surgical treatment of 301 patients with malignant tumors of the colon and rectum presenting to 2 small district general hospitals in 1972-1977 were analyzed. A total of 274 patients (91%) underwent surgery with an operative mortality of 8.7%. Curative resections were performed in 58% of the patients. The overall crude 5-yr survival rate was 32%. The crude 5-yr survival rates for curative resection, palliative procedures and inoperable patients were 47%, 11% and 0%, respectively. Survival rates were considerably improved in patients in the 40-to-50-yr group with 9-12 mo. duration of symptoms, and in those with early unfixed, resected tumors. It was diminished in patients with bowel perforation presenting as an emergency, and in patients with 2 wk or less duration of symptoms. Survival was not related to the site or grade of the tumor.
