Relationship between Tumor Enhancement, Edema,<i>IDH1</i>Mutational Status,<i>MGMT</i>Promoter Methylation, and Survival in Glioblastoma

Abstract

Imaging features are potentially predictive of IDH1 mutational status but were poorly correlated with MGMT promoter methylation. Edema stratifies survival in MGMT promoter methylated but not in unmethylated tumors; patients with methylated tumors with little or no edema have particularly long survival.
