Synopsis

A total number of 439 patients with esophageal squamous cell carcinoma (ESCC) were enrolled in this study. All patients scanned using StarVIBE sequences. We split the data randomly into training and independent test cohort in a ratio of 7 to 3. We proposed a method for feature selection to find the most useful features for survival analysis. The radiomics score combined with clinical variables achieved the highest consistency in the prediction of disease-free survival (DFS) with a C-index value of 0.682 in the test cohort and overall survival (OS) with a C-index value of 0.691 in the test cohort.
