Somatic alterations of driver genes in oligodendroglial tumors. (A) Driver gene mutations and copy number alterations were generated and visualized using OncoPrinter, which is included in the cBioPortal for Cancer Genomics software suite. (B) Kaplan–Meier analysis of progression-free survival (PFS) of patients with grade III oligodendroglial tumors with and without ARID1A mutations. (C) Kaplan–Meier analysis of PFS of patients with grade III oligodendroglial tumors with and without CDKN2A/B homozygous deletions.
