Consistently, in the cohorts used in this study, the median OS of the IDH-wildtype GBM are 11.5, 13.3, and 13.83 months in the CGGA-RNAseq cohort, TCGA-RNAseq cohort and TCGA-microarray cohort, respectively, while, those of the IDH-mutant GBM are 18.5 months (CGGA-RNAseq cohort), 34.13 months (TCGA-RNAseq cohort), and 35.9 months (TCGA microarray cohort). This evidence concerns the gene IDH1 and glioblastoma.
