Abstract:
Low-grade gliomas are the commonest brain tumor in children comprising heterogeneous pathological entities. Though the overall prognosis is good, unresectable, and recurrent or progressive tumors in eloquent areas of the brain remain major therapeutic challenge even with advances in chemotherapeutic strategies. With the evolving surge of molecular data, improved understanding of the biology of these tumors is now perceivable that could provide insights into novel therapies. We hope the new era will enable us to profile comprehensive histopathological/molecular classification and prognostic molecular markers in these tumors and guide us to tailor optimal targeted therapy.
Insights
Pediatric low-grade gliomas pose challenges, especially when unresectable. Advances in molecular data offer hope for tailored therapies and improved outcomes for these common childhood brain tumors.
