Two-thirds of all pediatric malignant central nervous tumors, including high-grade (glioblastoma, anaplastic astrocytoma) and low-grade (ganglioglioma, pilocytic astrocytoma) carcinomas, are gliomas. Low-grade glioma (LGG) exhibits genetic alterations caused by the BRAF kinase mutation, such as replacing glutamic acid (E) in place of valine (V) at the 600 positions, known as the V600E point mutation. Pediatric low-grade gliomas (PLGGs) also comprise around one-third of juvenile brain tumors and are the most frequent central nervous system tumors. Patients were randomized 2:1 to dabrafenib plus trametinib (D+T) or carboplatin plus vincristine (C+V). Where possible, complete surgical removal is the mainstay of treatment for progressing or symptomatic PLGG. Radiation therapy has historically been used to treat PLGG in both up-front and salvage scenarios. To delay or avoid the necessity for radiation therapy in young children with advancing or incompletely resected PLGG, chemotherapy was created in 1980. On 16 March 2023, the Food and Drug Administration approved the use of trametinib (Mekinist, Novartis) with dabrafenib (Tafinlar, Novartis) in pediatric patients suffering from LGG who require systemic therapy and are at least one year old. Nevertheless, early-stage clinical trials have produced encouraging results that may revolutionize the treatment of LGG in the near future.
