Refining the chemotherapy approach for older patients with colon cancer.

Population studies support an increased incidence of most cancers among older adults. Colorectal cancer has high prevalence in the aging population, with a median age of 69 years at diagnosis and 74 years at death. The vast majority of patients with colon cancer (CC) will require chemotherapy treatments during their disease course, challenging oncologists with the task of tailoring therapy for older patients with CC in the face of limited evidence-based data to guide them. Factors such as comorbidity, performance status, cognitive function, and social support may affect decision making and complicate tolerance of any recommended therapy. In recent years, attention to the specific needs of the aging population with cancer has given rise to the field of geriatric oncology in general, and has generated an increasing fund of knowledge on which to base chemotherapy delivery for this specific population of patients with CC. This article will review the available data specifically for chemotherapy management of older patients with CC in the postoperative and metastatic settings.
