BMI, body mass index; IDH, isocitrate dehydrogenase; KPS, Karnofsky performance status; MGMT, methylguanine-DNA methyltransferase; RPA, recursive partitioning analysis; WES, whole exome sequencing. Data are expressed as the number (%) unless otherwise specified. IDH1/2 mutation and MGMT promoter methylation status are based on the surgical pathology reports.
