Advance care planning for cancer patients: a systematic review of perceptions and experiences of patients, families, and healthcare providers.

Patients with advanced cancer may benefit from end of life (EOL) planning, but there is evidence that their willingness and desire to engage in advance care planning (ACP) varies. The reasons for this remain poorly understood. Previous reviews on ACP most commonly report outcome measures related to medical interventions and type of care. Synthesis of the literature, which aims to illuminate the salient characteristics of ACP and investigates the psychological and social features of preparation for the EOL, is required.
