Preoperative computed tomography‐guided disease‐free survival prediction in gastric cancer: a multicenter radiomics study

Purpose Preoperative and noninvasive prognosis evaluation remains challenging for gastric cancer. Novel preoperative prognostic biomarkers should be investigated. This study aimed to develop multidetector‐row computed tomography (MDCT)‐guided prognostic models to direct follow‐up strategy and improve prognosis. Methods A retrospective dataset of 353 gastric cancer patients were enrolled from two centers and allocated to three cohorts: training...
