title: Colorectal cancer in patients over 70 years old. A prospective study of operative results.
abstract: All patients (284, mean age 70.8 years) admitted with a diagnosis of primary colorectal cancer to our surgical department during the years 1984-87 were evaluated prospectively. We compare 170 (59.9%) patients > 70 years old and 114 (40.1%) patients < or = 70 years. The overall operability rate was 97.3% and the resectability rate 92.8%. The overall operative mortality rate was 2.1%, four patients in the older group and two patients in the younger group (NS). Among patients who underwent emergency surgery, the operative mortality was 6.1% (4 patients). The overall morbidity rate was 26.7% without significant differences between the two age-groups. A separate subset analysis was done to compare the very old patients (age > or = 80) to the old patients (age 70-79). There were no significant differences between these groups in tumor location, presentation and staging, as well as in operability rate and operative morbidity and mortality. The operative mortality in those over the age of 80 was 3.5%. We concluded that age should not be a determinant in consideration of operation for primary colorectal cancer, since operative mortality and morbidity are similar in both the elderly and their younger counterparts.
