AI Article Synopsis

  • A case of gemistocytic astrocytoma is presented, which unusually shows high intensity on both T1W and T2W MRI scans.
  • Typical astrocytomas are expected to show low density on T1-weighted images.
  • The high intensity in this case is attributed to the shortening of T1 relaxation time caused by a protein-rich cell structure in the tumor, with no signs of hemorrhage or other substances usually associated with such imaging characteristics.

Article Abstract

A gemistocytic astrocytoma demonstrating high intensity on both T1W and T2W MR images is reported. Astrocytoma usually shows low density in T1WI. This peculiar astrocytoma showed no hemorrhage, hemosiderin deposits, melanin or iron. Shortening of T1 relaxation time may be caused by protein hydration layer due to protein rich tumor cells.

Background And Objectives: IDH-wildtype glioblastoma multiforme (GBM) and grade 4 IDH-mutant astrocytoma are challenging to manage in oncology. This study explores the contrast between gross total resection (GTR) and supratotal resection (SupTR) for IDH-wildtype GBM and grade 4 IDH-mutant astrocytoma, aiming to summarize their influence on crucial clinical outcomes.

Methods: This systematic review was conducted in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines.

Background And Purpose: The characteristics and role of NOD-like receptor (NLR) signaling pathway in high-grade gliomas were still unclear. This study aimed to reveal the association of NLR with clinical heterogeneity of glioblastoma (GBM) patients, and to explore the role of NLR pathway hub genes in the occurrence and development of GBM.

Methods: Transcriptomic data from 496 GBM patients with complete prognostic information were obtained from the TCGA, GEO, and CGGA databases.

Background: Glioblastoma is the commonest malignant brain tumor and has a very poor prognosis. Reduced expression of the MGMT gene (10q26.3), influenced primarily by the methylation of two differentially methylated regions (DMR1 and DMR2), is associated with a good response to temozolomide treatment.

Isocitrate dehydrogenase 1/2 mutant (IDHmt) astrocytoma is considered a T cell-deprived tumor, yet little is known regarding the phenotypes underlying T cell exclusion. Using bulk, single nucleus and spatial RNA and protein profiling, we demonstrate that a distinct spatial organization underlies T cell confinement to the perivascular space (T cell cuff) in IDHmt astrocytoma. T cell cuffs are uniquely characterized by a high abundance of gemistocytic tumor cells (GTC) in the surrounding stroma.

This study aimed to investigate the genetic association between glioblastoma (GBM) and unsupervised deep learning-derived imaging phenotypes (UDIPs). We employed a combination of genome-wide association study (GWAS) data, single-nucleus RNA sequencing (snRNA-seq), and scPagwas (pathway-based polygenic regression framework) methods to explore the genetic links between UDIPs and GBM. Two-sample Mendelian randomization analyses were conducted to identify causal relationships between UDIPs and GBM.
