The principle aim of the present study was to elucidate research trends and issues related to school re-entry. We reviewed past studies concerning school re-entry support for children with chronic illness. A total of 36 papers were analyzed for the keywords of "school re-entry," "support," "pediatric cancer," and "chronic illness." The results revealed that the concerns regarding the children and school re-entry support roles of legal guardians, healthcare providers, teachers, etc., and specific examples of collaboration with other occupations. "Guaranty a right to learn " and "relationship maintenance" were noted as issues, and ensuring a system that can establish certain learning opportunities even if the enrollment status of the child changes, continued maintenance of relationships of the patient before the onset of disease, and support to maintain the relationship of healthcare providers and teachers who are involved after onset of the disease are necessary even after school re-entry.
