We here aim to replicate these findings in an independent trial cohort.We evaluate the treatment benefit of bevacizumab according to gene expression subtypes of pretreatment tumor samples (n = 123) in the GLARIUS trial (NCT00967330) for MGMT unmethylated glioblastoma patients with Kaplan-Meier analyses, log-rank tests and Cox regression models.Employing the Phillips classifier, bevacizumab conferred a significant PFS advantage in patients with proneural IDH wild-type tumors (10.4 vs. 6.0 months, p = 0.002), but no OS advantage (16.4 vs. 17.4 months, p = 0.6). Multivariable analysis adjusting for prognostic covariates confirmed the absence of a significant OS advantage from bevacizumab (hazard ratio, 1.05, 95 %K Bevacizumab (Other) %K Gene expression (Other) %K Glioblastoma (Other) %K Newly diagnosed glioblastoma (Other) %F PUB:(DE-HGF)16 %9 Journal Article %$ pmid:37787906 %R 10.1007/s11060-023-04470-9 %U https://inrepo02.dkfz.de/record/284416
