Abstract excerpt
BACKGROUND: High-grade IDH-wildtype gliomas are aggressive tumors with marked molecular heterogeneity. This study assessed whether tumor location reflects distinct developmental origins. METHODS: We retrospectively analyzed 5,945 high-grade IDH-wildtype gliomas using de-identified mutational and transcriptomic data. Tumors were grouped as cortical (e.g., frontal, temporal) or deep/dorsal midline (e.g., brainstem,...
