Background and aim: Gliomas are the most common primary brain tumors, classified according to their histopathological and genetic features. Tumorigenesis depends on alterations in different genes. The aim of this study was the identification of mutations in IDH1 and TERT genes in gliomas of Argentine pat...
Resumen Objetivo: Analizar características por resonancia magnética (RM) de gliomas IDH-mutados (grado II y III) en base a parámetros cualitativos, a fin de valorar el rendimiento del signo del mismatch T2-FLAIR y otras características morfológicas de los tumores, en predecir el estado del 1p/19q ...
Introdução: Os gliomas representam 80% dos tumores do sistema nervoso central. A Organização Mundial da Saúde (OMS) adicionou, em 2016, critérios moleculares na classificação dos gliomas. A fisiopatologia e os fatores de risco desses tumores ainda não são totalmente conhecidos. Objetivo: Realiz...
Introducción. Los gliomas son las neoplasias malignas primarias más frecuentes del sistema nervioso central, asociadas con una mortalidad y morbilidad elevadas. Las mutaciones en los genes IDH1 e IDH2 de la enzima isocitrato deshidrogenasa (IDH) son clave en la tumorogénesis, y son consideradas un fac...
Vasculogenic mimicry (VM) plays an important role in human glioma progression and resistance to antiangiogenic therapy as a compensatory neovascularization mechanism in malignant tumors. Caveolin-1 (Cav-1) has been found to contribute to VM formation. However, it remains largely unknown whether Cav-1 exp...
This work aimed to research the function of MARVEL domain-containing protein 1 (MARVELD1) in glioma as well as its functioning mode. Bioinformatics analysis was utilized to assess the MARVELD1 expression in glioma tissues and its relationship with grade and prognosis, based on The Cancer Genome Atlas (TC...

ABSTRACT The anesthesia for awake craniotomy (AC) is a consecrated anesthetic technique that has been perfected over the years. Initially used to map epileptic foci, it later became the standard technique for the removal of glial neoplasms in eloquent brain areas. We present an AC anesthesia technique co...
Abstract Background: Astrocytomas are cancer tumors of the central nervous system and represent the most common type of solid tumors during human childhood. In 2016, the World Health Organization established a molecular classification system to regroup tumor entities to achieve a more accurate diagnosis...

La Clasificación de Tumores del Sistema Nervioso Central de la OMS 2016 incorpora biomarcadores moleculares junto a las características histológicas clásicas, en un diagnóstico integrado, con el fin de definir distintas entidades de gliomas con la mayor precisión posible. Los estudios de perfiles m...
Abstract Cerebellar astrocytoma (low-grade glioma) is the most frequent tumor of the Central Nervous System in pediatric age, corresponding to 10-20% of brain tumors, having its maximum incidence at 5 years. Brain tumors are the second cause of death at this age, behind leukemias. Its most frequent clini...
