The aim of this umbrella review is to summarize and discuss the current state of research on information and other needs among migrant and ethnic minority cancer patients and survivors, as well as to provide a practical and comprehensive overview for medical personnel. In fact, although migrants and ethnic minorities with cancer show worse psychological and health-related quality of life outcomes, little is known about their needs during the different phases of cancer. Web of Science, PubMed, and PsycINFO databases were searched for systematic reviews on information and supportive care needs of ethnic minority and migrant cancer patients and survivors. From the 445 articles retrieved, 5 systematic reviews were included. During the diagnosis and therapy phase, almost all ethnic groups showed high needs for “cancer-specific”, “treatment-related”, and “prognosis” information. During the survivorship phase, high needs for “coping”, “rehabilitation”, and “prognosis” information were reported. Among mostly all migrant groups and ethnic minorities, information on the “general health care system” were among the most reported needs, especially on the topics of communication with medical personnel. Barriers towards the fulfillment of these needs were often reported in language and cultural differences. Supportive care needs concerning family and spirituality were not sufficiently met. Information needs on “body image/sexuality” were only present among certain minorities. Information and other needs are mostly similar among the various ethnic groups, as are the barriers towards them. However, some specific information or other needs are more present in some migrant groups or ethnic minority cancer patients and/or survivors than in others.
