In contrast, patients classified as alive were linked to favorable prognostic variables, including oligoastrocytomas and oligodendrogliomas, grade 2, IDH mutant, codeleted 1p19q, methylated MGMT promoter, absence of combined Chr7+/Chr10– (chromosome 7 gain and 10 loss), lack of TERT expression, ATRX mutant, and the proneural (PN) and neural (NE) transcriptome subtypes (Table 1). Here, TERT is linked to oligoastrocytoma.
