Expression data from primary Glioblastoma in adults

ABSTRACT: Gene expression profiling revealed over-representation of a distinct (proneural-like) expression signature in long-term survivors that was linked to IDH1/2 mutation. However, among the IDH1/2-wildtype patients, tumors from long-term survivors did not show distinct gene expression profiles and included proneural, classical and mesenchymal glioblastoma subtypes. We performed genome- and/or transcriptome-wide molecular profiling of primary tumor samples from 70 glioblastoma patients of the German Glioma Network, including 23 longterm survivors with >36 months overall survival (OS), 16 short-term survivors with <12 months OS, and 31 patients with intermediate OS For this study, we screened prospectively recruited patients with a histopathological reference diagnosis of glioblastoma, known KPS
