Update on Genetic Counselor Practice and Recommendations for Pediatric Cancer Predisposition Evaluation and Surveillance

Abstract

Abstract In July 2023, the American Association for Cancer Research held the second Childhood Cancer Predisposition Workshop, at which international experts in pediatric cancer predisposition met to update the previously published 2017 consensus statements on pediatric cancer predisposition syndromes. Since 2017, advances in tumor and germline genetic testing and increased understanding of cancer predisposition in patients with pediatric cancer have led to significant changes in clinical care. Here, we provide an updated genetic counseling framework for pediatric oncology professionals. The framework includes referral indications and timing, somatic and germline genetic testing options, testing for adult-onset cancer predisposition syndromes in children with and without cancer, evolving genetic counseling models to meet the increased demand for genetic testing, barriers to cancer genetic testing and surveillance in children, and psychosocial and equity considerations regarding cancer genetic testing and surveillance in children. Adaptable genetic counseling services are needed to provide support to pediatric oncology provider teams and diverse patients with pediatric cancer, cancer predisposition, and their families.
