Perspectives on functional status in older adults with cancer: An interprofessional report from the International Society of Geriatric Oncology (SIOG) nursing and allied health interest group and young SIOG

Most adults with cancer are over 65 years of age, and this cohort is expected to grow exponentially. Older adults have an increased burden of comorbidities and risk of experiencing adverse events on anticancer treatments, including functional decline. Functional impairment is a predictor of increased risk of chemotherapy toxicity and shorter survival in this population. Healthcare professionals caring for older adults with cancer should be familiar with the concept of functional status and its implications because of the significant interplay between function, cancer, anticancer treatments, and patient-reported outcomes. In this narrative review, we provide an overview of functional status among older patients with cancer including predictors, screening, and assessment tools. We also discuss the impact of functional impairment on patient outcomes, and describe the role of individual members of an interprofessional team in addressing functional impairment in this population, including the use of a collaborative approach aiming to preserve function.
