Glioblastomas (GBM) are the most common adult primary brain tumor and are unfortunately aggressive, relatively resistant to therapy, and have a corresponding poor prognosis. Los patólogos describen demasiada proteÃna como "sobreexpresada" y ninguna proteÃna como "nula". >> IDH1-or IDH2-mutant gliomas have been well-studied and associated with nearly twice the median overall survival as nonmutated counterparts (Cairncross et al. 2013 May 13;23(5):570-2. doi: 10.1016/j.ccr.2013.04.024. Primary glioblastomas largely equate to glioblastoma, IDH-wildtype, whereas secondary glioblastomas now equate to astrocytoma, IDH-mutant, WHO CNS grade 4. Las mutaciones en IDH1 están presentes en hasta el 7â14% de los pacientes con LMA y más comúnmente implican una sustitución de cisteÃna o histidina por arginina en el residuo 132, R132C y R132H, respectivamente (2). Cuando se examina bajo el microscopio, el glioblastoma se compone de astrocitos anormales que se parecen muy poco a los astrocitos que normalmente se encuentran en todo el sistema nervioso central (SNC).
