This review aimed to identify the unmet supportive care needs to conduct an integrative review of the literature, to identify the unmet supportive care needs of Arab people affected by cancer (patients and caregivers), and the impact of these needs on quality of life and psychosocial well-being. In July 2015 databases, search engines and electronic list servers were searched, with no limit on the year of publication. Reference lists of included articles and published reviews were also hand searched. Six studies met the inclusion criteria. Most studies examined the supportive care/ unmet needs of Arab cancer patients and their family caregivers. Language, communication, information, and the need to get relief from dependency were the most frequently reported unmet needs among Arab cancer patients. For immigrant Arab patients, physical unmet needs were higher than other migrant groups and native Anglo-Australians. Arab caregivers' unmet needs included concerns about providing suitable care for their family member, sharing their experience with other caregivers, obtaining information, and, in the case of pediatric cancers, dealing with siblings' emotional reactions. The existing literature exploring the unmet supportive care needs of Arab people affected by cancer is limited suggesting that comprehensive studies are needed to enhance our understanding of these needs and to inform service planning.
