ABSTRACT: Objective:Effective communication for cancer patients and/or caregivers can meet information needs, reduce caregiver burden, improve physical and mental health, and promote intimacy. The aim of this review was to identify the communication needs of cancer patients and/or caregivers and to explore their specific communication needs to guide the development of future communication interventions. Methods:Chinese and English databases were systematically searched from January 2010 to October 2019, including MEDLINE, CINAHL, PubMed, and the China Academic Journal Full-text Database. The key search terms used were "cancer" or "carcinoma" or "oncology" AND "patient" or "caregiver" or "carer" AND "communication" or "discussion" or "talk" AND "need" or "needs" or "desire.". Results:A total of 26 articles was identified and included in this review. The findings revealed the needs of cancer patients and/or caregivers in terms of communication target, content, style, timing, and preferences. Communication targets included health professionals, peers, caregivers, and patients. Communication content included illness-related, emotional support, daily life, sexuality, death, and a way to communicate with health professionals. Communication style needed to be expressed through such things as language and communication atmosphere. Communication timing mainly referred to before treatment and approaching death. Communication preferences were related to factors such as demographics and ethnic origin. Conclusions:Cancer patients and/or caregivers have different communication needs in terms of target, content, style, and communication timing. A better understanding of the unique communication needs of patients and/or caregivers will offer health professionals detailed information on designing appropriate interventions to support cancer patients and caregivers.
