[Geriatric assessment. Is it significantly helpful in selection of elderly tumour patients for a difficult therapy?]

With increasing life expectancy, a therapeutic decision raises the question of the primary goals to be aimed for. Is an absolute gain in age a goal equal to the preservation of an active life? While in younger patients the strategy followed by the patient and the doctor will usually be that of long-term survival, the decision making process for older patients with functional deficits is more challenging. Though functional deficits show a positive correlation with age, a causal relationship does not exist, which implies considerable inter-individual heterogeneity in the group of older patients. In particular, patients who have reached older ages "successfully" without any major limitations in their health should be considered for more intensive treatment strategies. At the same time, younger patients with relevant functional limitations and without any chance of improvement may not benefit from these interventions. The comprehensive geriatric assessment (CGA) offers the opportunity to describe and classify these deficits systematically. It therefore has a key role in the individual decision making process.
