Pediatric central nervous system primitive neuro-ectodermal brain tumors (CNS-PNETs) are rare tumors with ill-defined biological features. In this issue of Cell, Sturm et al. used state-of-the-art methods to interrogate these tumors' biology. Their integrated molecular analyses led them to propose a new molecular classification, with four new entities identified, that should get oncologists' at...
PURPOSE 3T magnetic resonance scanners have boosted clinical application of 1 H-MR spectroscopy (MRS) by offering an improved signal-to-noise ratio and increased spectral resolution, thereby identifying more metabolites and extending the range of metabolic information. Spectroscopic data from clinical 1.5T MR scanners has been shown to discriminate between pediatric brain tumors by applying mac...
Pediatric central nervous system tumors are the most common solid tumor of childhood. Of these, approximately one-third are gliomas that exhibit diverse biological behaviors in the unique context of the developing nervous system. Although low-grade gliomas predominate and have favorable outcomes, up to 20% of pediatric gliomas are high-grade. These tumors are a major contributor to cancer-relat...
Objective: One of the most frequent causes of death and acquired disability in the pediatric population is the Traumatic Brain Injury (TBI). TBI is secondary to falls, road traffic and vehicle collisions, child abuse and assaults. Penetrating brain injury is a severe form of traumatic brain injury. Blunt head injury is more frequent than TBI in children, but the second one carries a poor progno...
Pediatric low-grade gliomas are the most common tumors of the central nervous system in children, accounting for almost 50% of all childhood brain tumors. They are a heterogeneous group of tumors with different histologic subtypes. Most treatment studies address low-grade gliomas as a single entity, depriving us of histology-specific treatment outcomes. This is mostly due to a lack of understan...
KIT receptor tyrosine kinase is expressed in tumor endothelial cells of adult glioblastomas, but its expression in pediatric brain tumor endothelial cells is unknown. We assessed expression of KIT, phosphorylated KIT, stem cell factor (SCF) and vascular endothelial growth factor receptor-2 (VEGFR-2) in 35 juvenile pilocytic astrocytomas and 49 other pediatric brain tumors using immunohistochemi...
Kinase inhibitors are effective cancer therapies, but tumors frequently develop resistance. Current strategies to circumvent resistance target the same or parallel pathways. We report here that targeting a completely different process, autophagy, can overcome multiple BRAF inhibitor resistance mechanisms in brain tumors. BRAFV600Emutations occur in many pediatric brain tumors. We previously rep...
