Childhood Cancer Predisposition: An Overview for the General Pediatrician.

Abstract

Cancer predisposition syndromes (CPS), or genetic syndromes leading to increased cancer risk, are responsible for at least 10% of all childhood cancers. With advances in both tumor and germline sequencing, these syndromes have been uncovered both in patients with and without syndromic features and family history of cancer. Recognition of CPS in children and use of associated screening guidelines can improve morbidity and mortality from childhood cancer. Given the multidisciplinary approach needed for management of CPS, knowledge of clinical features and surveillance guidelines are essential for the general pediatrician. Pediatricians also play a vital role in anticipatory guidance regarding cancer prevention strategies and management of psychosocial stressors associated with ongoing screening. This article discusses 10 of the more common pediatric CPS, reasons to refer patients for CPS genetic testing and evaluation, and general cancer prevention strategies.
