Abstract:
INTRODUCTION:Brain tumors make up over a quarter of pediatric malignancies. Depending on the age of presentation and treatment, pediatric brain tumor survivors experience varying degrees of treatment induced morbidity and sequelae. Epigenetic mechanisms play a critical role in silencing of tumor suppressor genes and activation of driver genes involved in oncogenesis in different types of brain tumors. Epigenetic modifications in pediatric brain tumor patients may influence long-term survival and may refine the molecular response to treatment induced morbidity and sequelae. However, there is a dearth of studies on how epigenetics of pediatric brain tumors is connected with neurocognition and other treatment related sequelae in survivors. METHODS/RESULTS:In this review we explore epigenetic factors that may contribute to the survivorship and treatment of pediatric brain tumor patients. We focus on glioblastoma, medulloblastoma, and the neurocutaneous syndrome neurofibromatosis type-1 to highlight epigenetic biomarkers that can potentially serve not only as prognostic indicators of overall patient survival, but hopefully as indicators to the response to treatment neurocognitively and otherwise. CONCLUSIONS:Future studies will hopefully soon bridge the gap in our knowledge on how epigenetic modifications are linked to treatment related sequelae in pediatric brain tumor patients.
