Patients with IDH wild type anaplastic astrocytoma and glioblastoma had a significantly shorter median PFS (19.3 months vs. NR, p = 0.001) and median OS (43.5 months vs NR, p = 0.007) than those with IDH mutated grade III anaplastic astrocytoma and oligodendroglioma.

As of 2016, isocitrate dehydrogenase (IDH)-1 and IDH-2 mutations are part of the definition of an oligodendroglioma and may be seen in a significant subset of grade II-IV fibrillary astrocytomas.

A total of 135 cases consisted of 38 IDH-mutant [17 astrocytoma (AC), 13 oligodendroglioma (OD) and eight glioblastoma (GBM)], 87 IDH-wildtype (six AC, three OD and 78 GBM), and 10 diffuse midline glioma, H3K27M-mutant.

Trisomy of chromosome 7 in IDH mutated astrocytoma and PTEN mutations in IDH mutated oligodendroglioma are potential markers of poor prognosis, but require confirmation in larger series.

Secondly, when analyzed in molecular subgroups, we were similarly unable to detect a significant PFS or OS benefit in IDH MT/codel subgroup (N = 269; HR 1.47; 95% CI 0.92-2.34; P = 0.11 and HR 1.54; 95% CI 0.78-3.05; P = 0.21, respectively), oligodendroglioma with IDH MT/codel subgroup (N = 233; HR 1.33; 95% CI 0.79-2.21; P = 0.28 and HR 1.16; 95% CI 0.53-2.54; P = 0.70, respectively) or other relevant subgroups.

One hundred twenty-six tumors could be classified: 20 as type II (IDH mutation [mut], "astrocytoma"), 49 as type I (1p/19q codeletion, "oligodendroglioma"), 55 as type III (7+/10q- or TERTmut and 1p/19q intact, "glioblastoma"), and 2 as childhood glioblastoma (H3F3Amut), leaving 7 unclassified (total 91% classified).

Our data reveal that the methylation profiles in 23 of the 25 GC tumors corresponded to either IDH mutant astrocytoma (n = 6), IDH mutant and 1p/19q codeleted oligodendroglioma (n = 5), or IDH wild-type glioblastoma including various molecular subgroups, i.e., H3F3A-G34 mutant (n = 1), receptor tyrosine kinase 1 (RTK1, n = 4), receptor tyrosine kinase 2 (classic) (RTK2, n = 2) or mesenchymal (n = 5) glioblastoma groups.

Indeed, 1p36/19q13 has been shown successively to predict increased chemosensitivity and better prognosis, to be associated with frontal location in brain and classic oligodendroglioma morphology, to be mutually exclusive with high-level gene amplification, to be actually whole chromosome arms 1p/19q codeletion, to mediate a t(1;19)(q10;p10) and to be associated with IDH mutations.
