The influence of age on resection rates and postoperative mortality in 6457 patients with colorectal cancer.
Due to the ageing of the general population, the proportion of elderly patients with colorectal cancer has increased. In a registry-based study, we evaluated the influence of age and other variables on resection rates and operative risk. Resection rates and postoperative mortality rates (30-day) were analysed in 6457 patients with colorectal cancer, diagnosed from 1985 through 1992 in hospitals connected to the Rotterdam Cancer Registry. Overall, 87% of the patients underwent resection but resection rates were lower for patients older than 89 years (67%) and for patients with rectal cancer (83%). The postoperative mortality rate was 1% for patients younger than 60 years and steadily increased with age. For patients 80 years and older the operative risk was 10%. According to multivariate analysis gender, age, subsite and stage were defined as independent prognostic factors. In view of the lack of alternatives, elderly patients with colorectal cancer should not be denied surgery on account of chronological age alone. Even in patients over 90 years of age resections can be performed with acceptable risk.
