School performance of childhood cancer survivors in Korea: A multi-institutional study on behalf of the Korean Society of Pediatric Hematology and Oncology.

We found that 20% to 25% of survivors experienced peer-related difficulties upon returning to school. Patients who return to school, especially high school, should be provided more educational support to overcome low academic achievement. Particular concern is needed to the patients with brain tumors, who are at risk for significant academic and social difficulties and therefore may require more intensive support in school.
