Among 893 patients with colorectal cancer who underwent surgery in our department during the 10 years from 1982 to 1991, 44 patients over 80 years old were compared with patients aged 50 to 59 in terms of clinicopathological aspects, preoperative complications, postoperative complications and prognosis. The clinicopathological. characteristics of the group composed of patients over 80 years old included a lower incidence of cases with lymph node metastasis, a higher incidence of cases with cancer in other organ and a higher ratio of cases with stage II.<BR>In patients over 80 years old, the incidence of preoperative complications was higher and the ratio of resection was lower. However, concerning incidence of preoperative complications and survival rates, no significant difference was noted between those over 80 years old and those aged 50-59.<BR>In addition, R1 lymph node dissection was more frequently observed in patients over 80 years old. Based on the above results, surgical procedures with R1 lymph node dissection are generally recommended for patients over 80 years with colorectal cancer, as our retrospective study demonstrated they obtained almost the same postoperative results as patients aged 50-59 with colorectal cancer.
