[Chemotherapy for colorectal carcinoma in the elderly].

With nearly 50 % of all colorectal cancers being diagnosed in patients at the age of 70 or above colorectal cancer is a disease of the elderly. In an adjuvant setting, fit elderly patients can receive the same benefit from cytotoxic therapy as younger patients with an only slightly increased toxicity. In a palliative setting, the treatment of elderly patients with respect to clinical endpoints such as response, time to progression or overall survival is as effective as in their younger counterparts. In clinical studies, older patients are generally underrepresented and among the elderly patients involved in clinical studies there is a bias towards particularly fit patients. Therefore it is not possible to extrapolate the results of many randomized trials to all elderly patients. A Comprehensive Geriatric Assessment (CGA) should be applied to detect the diversities in the geriatric population. Based on this assessment elderly patients classified as suitable for chemotherapy should be enrolled into clinical trials for colorectal cancer.
