Résumé :

Gli autori si propongono di verificare l'utilità rispettiva della biopsia e della radiologia per identificare il grado di malignità dei gliomi cerebrali. L'esame critico della letteratura dimostra che la biopsia effettuata su materiale chirurgico è più affidabile di quella sterotassica, ma che comunque essa non è esente da errori tecnici o diagnostici e da pericoli. La TC è utile e non inferiore, anzi non raramente superiore, alla RM. In una ricerca personale condotta su 123 casi verificati istologicamente, la TC, riesaminata dallo stesso neuroradiologo senza conoscenza della diagnosi, senza e

Résumé :

Gli autori utilizzano una tecnica di radiochirurgia con acceleratore lineare dal 1982. La tecnica è basata su irradiazioni multiple ad archi intersecantisi focalizzate stereotassicamente su un bersaglio. Dopo che una valutazione meccanica e dosimetrica ha dimostrato la validità della procedura, la tecnica è stata impiegata su un gruppo selezionato di pazienti. Dal novembre 1982 al marzo 1988 sono stati trattati 155 casi. Tra loro 72 erano affetti da malformazioni arterovenose cerebrali, 16 da gliomi a bassa malignità, 8 da neurinoma dell'acustico, 8 da meningiomi e 11 da tumori maligni radiose

Abstract Glioma is one of the most aggressive cancers and represents approximately 80% of malignant brain tumors. The majority of CNS World Health Organization (WHO) grades 2-3 gliomas and a subset of high-grade gliomas (CNS WHO grade 4) harbor mutated isocitrate dehydrogenase 1 (IDH1R132H; mIDH1). Mutant IDH1 results in the accumulation of 2-hydroxyglutarate (2HG) which elicits profound changes in the glioma transcriptome/biology. Consequently, mIDH1 glioma patients have a significantly increased median survival compared to wildtype IDH1 patients. Recent data from our lab showed that mIDH1 gl

Résumé :

Abstract The brain tumor immune microenvironment (TIME) continuously evolves during glioma progression and a comprehensive understanding of the glioma-centric immune cell repertoire beyond a priori cell types and/or states is uncharted. Consequently, we performed single-cell RNA-sequencing on ~123,000 tumor-derived immune cells from 17-pathologically stratified, IDH (isocitrate dehydrogenase)-differential primary, recurrent human gliomas, and non-glioma brains. Our analysis delineated predominant 34-myeloid cell clusters (~75%) over 28-lymphoid cell clusters (~25%) reflecting enormous heteroge

Résumé :

Abstract Isocitrate dehydrogenase 1/2 mutations (IDHmut) define a subtype of glioma with profound epigenetic dysregulation through genomic hypermethylation. IDHmut gliomas are incurable and fatal, demonstrating new treatments are needed. These mutations are common in other solid tumors, including chondrosarcoma (CS) and intrahepatic cholangiocarcinoma (ICC). Histone deacetylase (HDAC) enzymes compose a class of epigenetic drug targets utilized clinically to treat cancer, but their potential against IDHmut gliomas has not been extensively studied. We previously showed that IDHmut glioma culture

Résumé :

Abstract Gliomas account for more than one-third of brain tumors in children, with high fatality rate despite aggressive adjuvant treatment. Two-thirds of survivors suffer from health conditions due to the toxicity of conventional therapies. Notably, gliomas with the BRAFV600E mutation, occurring in ~20% of all glioma cases, are difficult to treat and have a high risk for progression, especially when combined with CDKN2A deletion. The mechanisms for glioma progression remain unclear and unraveling them could lead to therapies that inhibit glioma progression, preventing high-grade gliomas. Obje

Résumé :

Abstract BACKGROUND Mutations in isocitrate dehydrogenase (IDH) 1 or 2 define glioma classification and determine the biology of these tumors. Although IDH is an essential enzyme in the cellular metabolism, powerful genome-wide analyses focus mostly at the genetic and epigenetic levels, while differences between distinct glioma entities at the proteomics, metabolomics, and functional levels are still poorly understood. Here, we provide an integrative multi-omics analysis of glioma patients to reveal metabolomic vulnerabilities of gliomas stratified by IDH mutation. MATERIAL AND METHODS We perf

Object Biomarkers for the diagnosis and prognosis of gliomas are lacking. To elucidate new diagnostic and prognostic targets, a routine method is used to evaluate differences between the protein profile of normal and tumor cells. The object of the current study was to investigate novel differentially expressed proteins and their roles in gliomas. Methods Differences in the protein profile were compared using 2D polyacrylamide gel electrophoresis using C6 glioma cells and rat astrocytes. The mRNA and protein expression of ANXA2, PGAM1, and CALR were analyzed in glioma tissues and normal brain t

Résumé :

Abstract Background Diffuse gliomas are fatal primary brain tumors that are poorly immunogenic. The basis for insufficient anti-tumor immunity in diffuse gliomas is not understood. Mutations in isocitrate dehydrogenases (IDH1 and IDH2) promote diffuse glioma formation through epigenetic reprogramming of a number of genes, including immune-related genes. Here, we identify epigenetic dysregulation of natural killer (NK) cell ligand genes as significant contributors to immune escape in glioma. Methods We analyzed the TCGA database for immune gene expression patterns in IDH mutant or wild-type gli

Abstract Background and Theory MRI and histopathological tissue sampling are routinely done as part of the diagnostic work-up of patients with glioma. MRI provides anatomical images with high resolution and excellent soft-tissue contrast. But this modality has limitations in identifying tumor grade, true tumor extension and differentiate viable tumor tissue from treatment induced changes. PET can provide quantitative information of cellular activity and metabolism, and may therefore have additional value compared to MRI alone.

Background. Glioma is the most common primary intracranial tumor and is associated with poor prognosis. Identifying effective biomarkers for glioma is particularly important. MXRA5, a secreted glycoprotein, is involved in cell adhesion and extracellular matrix remodeling and has been reported to be expressed in many cancers. However, the role and mechanism of action of MXRA5 in gliomas remain unclear. This study was aimed at investigating the role of MXRA5 at the transcriptome level and its clinical prognostic value.

Genetic analysis in glioma has been developed recently. Spinal cord glioma is less common than intracranial glioma. Thus, the clinical significance of genetic mutations in spinal cord gliomas remains unclear. Furthermore, because the spinal cord is an important communication channel between the brain and the rest of the body, increased attention should be paid to its functional prognosis. In this study, we investigated the functional prognosis and driver genetic mutations in eight patients with spinal cord gliomas (World Health Organization grade I, three cases; grade II, two cases; grade III/
