To assess glioblastoma heterogeneity using pre-treatment MR imaging texture analysis and evaluate its relationship with overall patient survival time.
Analyzed pre-treatment postcontrast T1-weighted MRI scans from 133 patients with primary glioblastoma from The Cancer Genome Atlas, stratified into long-term (≥12 months, n=67) and short-term (<12 months, n=66) survival groups.
Extracted three texture types—co-occurrence matrix (local), run-length matrix (regional), and histogram (global)—and evaluated classification performance using support vector machine models with recursive feature elimination.
Co-occurrence matrix features yielded the highest classification performance among individual texture categories, while combining all feature types achieved the best survival stratification.
Recursive feature elimination identified an optimal subset of 43 top-ranked features, with the top 10 consisting of seven run-length matrix and three co-occurrence matrix features.

Implication

Retrospective study demonstrates that MRI texture analysis stratifies survival in glioblastoma, indicating that local and regional tumor heterogeneity predicts clinical prognosis.
