[Geriatric assessment prior to oncological therapy].

Ageing is the single most important risk factor for cancer. This is also true for most cancer diseases of the genitourinary tract. In combination with the demographic changes in Germany and most other countries, the consequence is a substantial increase in the number of elderly patients with cancer. Most therapies in oncology have a high risk for toxic side effects. Ageing is a very heterogeneous process. The chronological age of a patient insufficiently reflects the individual resources, deficits and risk factors but this can be assessed by a structured geriatric assessment. Integration of geriatric assessment into oncological treatment decisions is still low and is one of the major tasks in cancer care in the future.
