Age, Karnofsky performance status (KPS), and extent of surgery are all prognostic in GBM [2, 3], and more recently prognostic biomarkers have been described including O6-methylguanine-DNA methyltransferase (MGMT) promoter methylation [4, 5], isocitrate dehydrogenase 1 or 2 gene mutations [6, 7], and subventricular zone (SVZ) involvement [8]. Here, MGMT is linked to glioblastoma.
