title: Colorectal cancer treatment in elderly patients: an update on recent clinical studies.
abstract: Colorectal cancer (CRC) is one of the most common cancers in the Western world, with > 500,000 new cases diagnosed each year. One of the strongest risk factors for colon cancer is age. Physicians and their older patients commonly face the dilemma of whether to give/receive systemic chemotherapy for CRC. Evidence supports similar survival benefits with adjuvant and palliative chemotherapy in elderly patients compared with younger age groups. Data on treatment- related side effects did not reveal a different toxicity profile for elderly patients. The safety and efficacy of systemic chemotherapy in fit older patients were proven, and this group of patients could be enrolled in clinical trials. Conversely, frail older patients are more likely to suffer adverse outcomes when faced with stressors and might not benefit from chemotherapy. Despite a growing body of data, a great deal of work is still needed to establish optimal strategies to care for patients diagnosed with cancer later in life. There is a paucity of reports published in the literature because of the difficulty in routinely collecting such data. We report an overview of recent studies (clinical trials, pooled analysis, and population studies) to provide more information and to identify new and better treatment options.
