According to the results of the current study, histologic IDH-wildtype diffuse astrocytic gliomas of WHO grade II or III that carry EGFR amplification, +7/−10 or TERT promoter mutation are associated with significantly shorter survival compared to patients with other WHO grade II or III gliomas, and outcomes are similar to those in patients with IDH-wildtype glioblastoma (27). The gene discussed is EGFR; the disease is glioblastoma.
