Radiotherapy has become a part of the standard treatment of high-grade gliomas. Studies have shown that high-dose radiation results in more effective tumor control but at the cost of radionecrosis and other radiation-related side effects. Despite advancing techniques in stereotaxy and precise radiotherapy delivery techniques, studies published for stereotactic radiosurgical treatment of high-grade gliomas have not been unanimous, with large trials showing no survival benefit compared with conventional conformal radiotherapy. New imaging modalities have been studied with the hope to improve accuracy in the planning of radiosurgical treatments. However, further large scale studies are needed to confirm these results.

Background: Central nervous system tumors (CNSTs) represent a significant oncological challenge in pediatric populations, particularly in developing regions where access to diagnostic and therapeutic resources is limited.
Methods: This research investigates the epidemiology, histological classifications, and survival outcomes of CNST in a cohort of pediatric patients aged 0 to 19 years within a 25-year retrospective study at the Civil Hospital of Guadalajara, Mexico, from 1999 to 2024.
Results: Data was analyzed from 273 patients who met inclusion criteria, revealing a higher incidence in males (51.
Does Personality Influence the Quality of Life of Patients with Brain Tumors Treated with Radiotherapy?

Understanding the role of personality traits in shaping treatment outcomes is crucial given the multifaceted challenges posed by brain tumors and the significant adverse impact of radiotherapy (RT) on patients' well-being. This study aimed to provide insights into how personality traits affect psychosocial well-being and quality of life during RT in patients with high-grade malignant brain tumors. Personality traits in patients with high-grade glioma were assessed using the Eysenck Personality Questionnaire-Revised (EPQ-R).

Article Synopsis
- Canine high-grade glioma (HGG) is a severe form of cancer that's hard to treat, largely due to differences in tumor cell types and how tumors adapt after treatment, especially in breeds like French bulldogs.
- Immunotherapy shows promise in extending survival rates but has led to poor outcomes specifically in French bulldogs, prompting research into genetic differences in their tumors compared to other breeds like boxers and Boston terriers.
- Through RNA sequencing, the study found that French bulldog tumors exhibit unique gene expression patterns and show significant changes in immune-related pathways after treatment, contributing valuable insights for developing targeted therapies for different dog breeds and potential links to human glioblastoma.

Malignant gliomas are heterogeneous tumors, mostly incurable, arising in the central nervous system (CNS) driven by genetic, epigenetic, and metabolic aberrations. Mutations in isocitrate dehydrogenase (IDH1/2) enzymes are predominantly found in low-grade gliomas and secondary high-grade gliomas, with IDH1 mutations being more prevalent. Mutant-IDH1/2 confers a gain-of-function activity that favors the conversion of a-ketoglutarate (α-KG) to the oncometabolite 2-hydroxyglutarate (2-HG), resulting in an aberrant hypermethylation phenotype.
