 note = {From 1978 to 1996, 69 patients who were 80 years of age or older (Group Ⅰ), 75 patients who were between 75 and 79 years of age (Group Ⅱ) and 618 patients who were between 50 and 69 years of age (Group Ⅲ) received surgical treatment for colorectal cancer in our department, A retrospective comparative study of the three groups was made to assess the relevant pathological and surgical factors, preoperative co-existent disease and postoperative complications, postoperative mortality and survival rates, Statistically significant differences were observed in lymph node dissection, the frequency of preoperative co-existent disease, and the frequency of total postoperative complications between Group Ⅰ and Group Ⅲ. The total perioperative mortality rates and 3 years survival rates of the three groups were not significantly different, These results led us to the conclusion that a better prognosis for elderly patients can be achieved if surgery is performed.Therefore, better management and a better rationale governing operative procedures are needed for the treatment of colorectal cancer},
