Specifically, the TCGA dataset included 153 GBM (mean age 60 y.o., 99 male and 54 female patients), and 505 LGG samples (mean age 43 y.o., 279 male and 226 female patients), and overall survival (OS), progression-free survival (PFS) [17], MGMT promoter methylation (only for GBM samples) [18], and IDH mutation statuses were extracted [17]. This evidence concerns the gene MGMT and glioblastoma.
