Irinotecan in the treatment of elderly patients with advanced colorectal cancer

Irinotecan is an active drug in the first and subsequent lines of chemotherapy for patients with advanced colorectal cancer. Frequently, the elderly patients are excluded from receiving irinotecan alone or in combination, and on many occasions these patients receive an initial reduced dose of this drug. This revision has been focused in the role of irinotecan in elderly patients.Material and methodsData from pharmacokinetic studies, comparative analysis of prospective trials according to age and prospective studies with irinotecan alone or irinotecan-combinations in the elderly have been revised and put into context.ResultsEither pharmacokinetic and clinical data suggest that fit elderly patients may tolerate irinotecan as well as the younger population. Response rate and survival achieved in elderly patients with irinotecan combinations seem to be equivalent to that obtained in younger patients.ConclusionElderly patients with advanced colorectal cancer should be carefully evaluated in order to be classified as fit or not fit through a comprehensive geriatric assessment. For the group of fit elderly patients, irinotecan may be used as in the younger population.
