2301por Raghu, Ashley L. B., Chen, Jason A., Valdes, Pablo A., Essayed, Walid Ibn, Claus, Elizabeth, Arnaout, Omar, Smith, Timothy R., Chiocca, E. Antonio, Peruzzi, Pier Paolo, Bernstock, Joshua D.“…One recent series of cHGG included the subclasses of (1) high-grade astrocytoma with piloid features (HGAP, ~31% of tumors); (2) H3K27M diffuse midline glioma (~8%); and (3) isocitrate dehydrogenase (IDH) wildtype glioblastoma (~43%). The latter had an unusually low-frequency of epidermal growth factor receptor (EGFR) and high-frequency of platelet-derived growth factor receptor alpha (PDGFRA) amplification, reflecting a different composition of methylation classes compared to supratentorial IDH-wildtype tumors. …”

CDKN2A homozygous deletion predicted worse outcomes in the overall patient population, particularly in IDH-mutant 1p/19q oligodendrogliomas (grade 3). …”
