Purpose: The aim of this study was to avoid radiotherapy and to induce an objective response in children with low-grade glioma (LGG) using a simple chemotherapy regimen based on cisplatin and etoposide.
Patients And Methods: Thirty-four children (median age, 45 months) with unresectable LGG were treated with 10 monthly cycles of cisplatin (30 mg/m(2)/d on days 1 to 3) and etoposide (150 mg/m(2)/d on days 1 to 3). Tumor originated in the visual pathway in 29 patients, in the temporal lobe in two, in the frontal lobe in two, and in the spine in one. Eight children were affected by neurofibromatosis type 1. Objective tumor response and toxicity were evaluated by magnetic resonance imaging and neurologic and functional tests at 3-month intervals.
Results: An objective response was obtained in 24 (70%) of 34 patients, whereas the others had stable disease. None of the children were electively irradiated. In 31 previously untreated children, overall survival was 100% and progression-free survival was 78% at 3 years, with a median follow-up of 44 months. Acute toxicity was unremarkable; 28% patients evaluated for acoustic neurotoxicity revealed a loss of perception of high frequencies.
Conclusion: Cisplatin and etoposide combined treatment is one of the most active regimens for LGG in children and allows avoidance of radiotherapy in the vast majority of patients.

There is major interest in deintensifying therapy for isocitrate dehydrogenase-mutant low-grade gliomas, including with single-agent cytostatic isocitrate dehydrogenase inhibitors. These efforts need head-to-head comparisons with proven modalities, such as chemoradiotherapy. Ongoing clinical trials now group tumors by intrinsic molecular subtype, rather than classic clinical risk factors.

The term "low-grade glioma" historically refers to adult diffuse gliomas that exhibit a less aggressive course than the more common high-grade gliomas. In the current molecular era, "low-grade" refers to World Health Organization central nervous system grade 2 gliomas almost always with an isocitrate dehydrogenase (IDH) mutation (astrocytomas and oligodendrogliomas). The term "lower-grade gliomas" has emerged encompassing grades 2 and 3 IDH-mutant astrocytomas and oligodendrogliomas, to acknowledge that histological grade is not as important a prognostic factor as molecular features, and distinguishing them from grade 4 glioblastomas, which lack an IDH mutation.

Background: Pediatric low-grade gliomas (pLGGs) have an overall survival of over 90%; however, patients harboring a BRAF alteration may have worse outcomes, particularly when treated with classic chemotherapy. Combined BRAF/MEK inhibition following incomplete resection demonstrated improved outcome in BRAF altered pLGG compared to combined carboplatin/vincristine chemotherapy and is now considered the standard FDA-approved treatment for this group of tumors. The aim herein was to investigate the efficacy and tolerability of single agent BRAF inhibitor treatment in BRAF altered pLGG.

Low-grade glioma (LGG) is a primary, slow-growing brain tumor; however, its treatment and prognosis remain challenging. In this study, we analyzed cancer data from the TCGA database, focusing particularly on the expression of the CDKN3 gene in LGG. The results showed that high CDKN3 expression in LGG patients was significantly associated with poor survival outcomes.

Aim: To evaluate the diagnostic performance of nonenhanced magnetic resonance imaging (MRI) in grading glioma and correlating isocitrate dehydrogenase (IDH) mutation status.
Materials And Methods: Patients with diagnoses confirmed by postoperative pathology were enrolled. Quantitative parameters, including the relative amide proton transfer-weighted (rAPTW), relative cerebral blood flow (CBF), and apparent diffusion coefficient (ADC) were applied to grade gliomas and correlate IDH mutation status.
