摘要: In recent years, important advances have been achieved in the understanding of molecular biology glioblastoma multiforme (GBM); thus, complex genetic alterations and genomic profiles, which recurrently involve multiple signaling pathways, defined, leading to first molecular/genetic classification disease. this regard, different pathways appear distinguish primary (eg, EGFR amplification) versus secondary IDH1/2 or TP53 mutation) GBM. Such target distinct combinations growth factor receptor–ras as well phosphatidylinositol 3-kinase/phosphatase tensin homolog/AKT, retinoblastoma/cyclin-dependent kinase (CDK) N2A-p16 INK4A , TP53/mouse double minute (MDM) 2/MDM4/CDKN2A-p14 ARF cells that present features associated with key stages normal neurogenesis (normal) central nervous system cell types. This translates into well-defined profiles recently classified by The Cancer Genome Atlas Consortium four subtypes: classic, mesenchymal, proneural, neural Herein, we review most relevant GBM, specific involved, overall profile genetically heterogeneous group malignant tumors.
