title: Colorectal cancer in patients over 80 years of age.
abstract: Between January 1, 1973, and December 31, 1986, 1,734 patients underwent colorectal resections for carcinoma. Patients were divided into two groups: Group I included 163 patients aged greater than or equal to 80 years on first presentation; Group II comprised 1,571 patients aged less than 80 years. The total perioperative mortality rates for the elderly and young group were 15.3 percent and 5 percent, respectively (P less than 0.001). The surgical mortality rates after elective operations in Groups I and II were 7.4 and 4.5 percent, respectively, and were not statistically different. Emergency surgery was associated with a significantly higher incidence of perioperative deaths at any age (P less than 0.001). In the elderly group, most deaths (88 percent) resulted from complications of coexisting medical disorders or thromboembolic complications. The 5-year survival for the young and elderly group were 46.2 percent and 35 percent, respectively (P less than 0.05). However, excluding patients dying from nonmalignant disease, the 5-year survival rate did not differ significantly between the two groups of patients (49.5 percent vs. 41.2 percent).
