IntroductionPediatric low-grade gliomas (PLGG) are the most common primary central nervous system tumor in children. Patients in whom gross total resection can be achieved have an excellent overall (OS) and event-free survival (EFS) and do not require adjuvant therapy. However, children with unresectable tumors often experience multiple progressions and require additional treatment.Conventional chemotherapyRadiotherapy results in long-term tumor control, but it is associated with significant toxicity, making chemotherapy the preferred therapeutic option. Several chemotherapy combinations have been found to be successful in PLGG, but 5-year EFS has been below 60 % with most of them.Molecular-based treatmentRecent molecular advances have led to a better understanding of the molecular pathways involved in the biology of LGG, allowing the development of promising tumor-specific, molecularly targeted therapies. |
