Multi‐pronged analysis of pediatric low‐grade glioma and ganglioglioma reveals a unique tumor microenvironment associated with BRAF alterations

Brain Pathology, Volume 35, Issue 6, November 2025.
A multi pronged analysis approach revealed distinct neoplastic populations in PA and GG. Non‐neoplastic populations in PA showed higher levels of immune mobilizing chemokines in PA compared to GG. Abstract Pediatric low‐grade gliomas (pLGG) comprise 35% of all brain tumors.

Molecular Landscape of Pediatric Low‐Grade Gliomas: Insights From RNA‐NGS and Bioinformatic Analysis

Genes, Chromosomes and Cancer, Volume 64, Issue 10, October 2025.
ABSTRACT Pediatric low‐grade gliomas (pLGG) are the most common group of childhood brain tumors. Genetic alterations in the RAS–RAF–mitogen‐activated protein kinase (MAPK) pathway are the molecular drivers in the vast majority of pLGG. A large proportion of pediatric pLGG are characterized by the presence of fusion genes.

The prognostic impact of TERT promoter mutations in glioblastomas is modified by the rs2853669 single nucleotide polymorphism [PDF]

, 2016
Human hotspot TERT promoter (TERTp) mutations have been reported in a wide range of tumours. Several studies have shown that TERTp mutations are associated with clinicopathological features; in some instances, TERTp mutations were considered as ...

Anatomy‐Guided, Modality‐Agnostic Segmentation of Neuroimaging Abnormalities

Human Brain Mapping, Volume 46, Issue 14, 01 October 2025.
Region ModalMix is a data augmentation strategy that leverages brain parcellations to improve MRI‐based tumor segmentation under missing modality conditions. By mixing anatomical regions across available modalities during training, our framework enhances model robustness, supporting more reliable decision making with incomplete multimodal neuroimaging ...

Tumor‐related epilepsy in glioma: A multidisciplinary overview

Epilepsia, Volume 66, Issue 10, Page 3621-3641, October 2025.
Abstract Seizures are a common and challenging symptom in brain tumors, affecting approximately 60% of patients. Tumor‐related epilepsy (TRE) in glioma patients requires personalized and dynamic management in a multidisciplinary environment, especially for its intricate pathophysiology and unpredictable disease evolution. This investigation provides an
