Despite the abundance of studies concerning caring for patients with cancer, less is known about caring for an older cancer survivor (≥65 years). We aimed to systematically gather literature about the psychosocial well-being of caregivers of older cancer survivors and to identify possible risk factors for developing psychosocial problems. Fourteen articles met the following inclusion criteria: articles about (a) cancer, (b) informal caregivers, (c) older survivors and a (d) curative setting. After critical appraisal, nearly all were considered to be of moderate-to-strong quality.
