Targeted therapy and elderly people: A review.

The use of targeted therapy (TT) has radically changed the outcome of various cancers and introduces the era of personalised medicine. Elderly patients (≥65 years) represent the majority of cancer diagnoses and deaths by age group with an increase expected over the next decade. This group of patients is heterogeneous with three categories of patients: fit, vulnerable and frail, with specific treatment for each subgroup. In this review, we assess safety and efficacy of TT in elderly patients, principally from data of pivotal clinical trials with subgroup analysis, but elderly people represented a small percentage of the total number of patients. Few specific trials have been carried out for TT in elderly people with most patients considered to be fit. However, tolerance and efficacy of TT in elderly patients seems similar to that for younger patients, with an increase in incidence of specific adverse events in elderly patients for selected TTs. An adapted geriatric selection and strict monitoring could help to decrease toxicity, and specific clinical trials for elderly cancer patients would be useful. Copyright Â
