An integrative genomic analysis, performed on 293 glioma patients by the Cancer Genome Atlas Network, showed that patients with oligodendrogliomas (IDH-mutant, 1p/19q codel) had a better overall survival (OS) than those with astrocytomas [13•, 14•], which was consistent with other reports [15]. The gene discussed is IDH2; the disease is astrocytoma (excluding glioblastoma).
