Assessment of Primary Colorectal Cancer Heterogeneity by Using Whole-Tumor Texture Analysis: Contrast-enhanced CT Texture as a Biomarker of 5-year Survival

Purpose To determine if computed tomographic (CT) texture features of primary colorectal cancer are related to 5-year overall survival rate. Materials and Methods Institutional review board waiver was obtained for this retrospective analysis. Texture features of the entire primary tumor were assessed with contrast material–enhanced staging CT studies obtained in 57 patients as part of an ethically approved study and by using proprietary...
