abstract
Glioblastoma (GB) is the most common and most aggressive form of diffuse glioma, with a median overall survival of 15 months after standard of care.1 Young GB patients (<40 years old) may carry isocitrate dehydrogenase 1 or 2 (IDH1/2) mutations or, in rare instances, harbor H3F3A or HIST1H3B mutations. Other cases are wild-type for those genes and harbor gain of chromosome (chr) 7, loss of chr 10, and epidermal growth factor receptor (EGFR) amplification (amp). IDH1/2 mutations are associated with longer survival (24 mo), whereas...
