The status of the prognostic glioma biomarkers O (6)-methylguanine-DNA methyltransferase (MGMT) promoter (methylated or unmethylated), isocitrate dehydrogenase 1 and 2 (IDH1/2) (wild-type or mutated), phosphatase and tensin homolog (PTEN) (wild-type or deleted), and epidermal growth factor receptor (EGFR) (amplified or mutated) in the tumors are presented in Table 1.
