[Chemotherapy of elderly patients with colorectal cancer].
Elderly patients will be the largest group of oncology patients in the future. Because of minimal participation of older patients in randomized clinical trials there is a lack of evidence-based data to make correct decisions with regard to chemotherapy and/or targeted therapy in this age group. Elderly patients have similar benefits from systemic therapies as younger counterparts, but many elders have substantial co-morbidities, which may limit the life expectancy and the effectiveness of systemic therapy. Close collaboration between oncologists and geriatrists will help make decisions on the management of elderly patients suffering from cancer.
