[Surgical treatment of colorectal carcinoma in the elderly].

Colorectal carcinoma is one of the most frequent tumor entities worldwide. The treatment of elderly and mostly polymorbid patients is an outstanding challenge in view of the demographic change with a continuously aging community. Due to the demographic changes the numbers of elderly (>65 years) and very old (≥80 years) patients are steadily increasing in surgical cohorts. This has resulted in higher morbidity and mortality rates in comparison to younger patients, with increased wound healing and cardiovascular complications but with comparable numbers of anastomotic insufficiency. Multivariate analysis revealed age ≥80 years, higher ASA status and emergency operations as independent risk factors for increased in-hospital mortality. With respect to the localization of colorectal cancer a shift to the right has been observed with increasing patient age. Whether minimally invasive surgical techniques can reduce postoperative morbidity and mortality rates in elderly patients requires further evaluation. Nevertheless, a reduction of both was reported without compromising the oncological result. Elderly patients require individualized treatment modalities, which take the extent of comorbidities and personal environment into consideration. So far, the cohort of octogenarians has not been adequately considered in current guidelines; therefore, geriatric expertise is recommended to be able to make a better assessment of benefit-risk ratios, as age itself has no impact on the decision for therapy.
