A STUDY OF OPERATIONS FOR COLORECTAL CANCER IN AGED PATIENTS OVER 85

Eighteen aged patients over 85 who were operated on for colorectal cancer at the hospital were subjected to a study to elucidate their clinicopathological characteristics and the significance of such operations. 1) Most patients were detected having a colorectal cancer in an advanced stage, but their lesions were predominantly localized in the large intestine. 2) In 12 (66.7%) out of 14 patients who had no liver, peritoneal, and other distant metastases, dissection of lymph nodes of group I resulted in the curability A. 3) Original cancer deaths were few among the curability A patients and the 5-year survival rate was 53.8%. 4) About half of the patients fell in postoperative delirium. 5) Many patients had some underlying diseases preoperatively, but strict perioperative management permitted to avoid postoperative complications. We think that the significance of operations for aged patients with colorectal cancer may not lie in operation itself, but the importance of stric and proper perioperative management should be emphasized.
