Family caregivers provide substantial care for patients with advanced cancer, while suffering from hidden morbidity and unmet needs. The objectives of this review were to examine risk factors associated with caregiving for patients with advanced cancer, evaluate the evidence for pertinent interventions, and provide a practical framework for palliative care of caregivers in oncology settings. We reviewed studies examining the association of factors at the level of the caregiver, patient, caregiver-patient relationship, and caregiving itself, with adverse outcomes.
