This analysis corroborated that EGFR alterations were independent good prognostic markers of OS in patients with IDH‐wildtype GBM (p = 0.023; Table 3) and unmethylated MGMTp was an independent poor prognostic marker of OS in patients with IDH‐wildtype GBM (p < 0.001; Table 3). This evidence concerns the gene EGFR and glioblastoma.
