Major or local surgery for cure in early rectal and sigmoid carcinoma--a prospective evaluation.

The results of different types of treatment for early cancer in 158 out of 1,300 patients with rectal and sigmoid cancer were evaluated in a prospective study from 1979 to 1984. Radical surgery was performed in 121 patients (mean age 66 years) with cancer Dukes' A (median diameter 3 cm), while 37 patients (mean age 71) with smaller cancers (median 2 cm) had polypectomy or local excision. Post-operative complications were significantly more frequent in the first group. No patients in any of the two groups with carcinoma in pedunculated adenomas or within the upper half of the submucosa or above 9 cm from the anal verge had recurrent cancer. CEA-measurements had no prognostic value. No difference was found in crude or cancer-related death between the two groups. The overall results support the use of local treatment in elderly patients with complicating disease, having small cancers, not penetrating the tunica muscularis externa of the rectosigmoid wall.
