Radiogenomics correlation between MR imaging features and mRNA-based subtypes in lower-grade glioma.


ABSTRACT: BACKGROUND:To investigate associations between lower-grade glioma (LGG) mRNA-based subtypes (R1-R4) and MR features. METHODS:mRNA-based subtyping was obtained from the LGG dataset in The Cancer Genome Atlas (TCGA). We identified matching patients (n?=?145) in The Cancer Imaging Archive (TCIA) who underwent MR imaging. The associations between mRNA-based subtypes and MR features were assessed. RESULTS:In the TCGA-LGG dataset, patients with the R2 subtype had the shortest median OS months (P??5%, OR: 14.733; P??5%, OR: 0.14; P?
