Managing Older Patients With Colorectal Cancer

Abstract

Colorectal cancer (CRC) is predominantly a disease of older persons, and our population is aging. Physicians and their older patients commonly face the dilemma of whether or not to give/receive systemic chemotherapy for CRC. Evidence supports the safety and efficacy of systemic chemotherapy in fit older patients motivated enough to enroll onto clinical trials. Conversely, frail older patients are more likely to suffer adverse outcomes when faced with stressors and may not benefit from chemotherapy. However, the majority of patients are neither fit nor frail, and current evidence is insufficient to either quantify or qualify the benefit of chemotherapy for this intermediate group of patients. Thus, treatment decisions must be individualized based on each older person's physical state (eg, their function and degree of comorbidity) and values. 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.
