This is a prospective, multi-center trial conducted at 4 high-volume gastric cancer centers in China (Nanfang Hospital of Southern Medical University; Sun Yat-Sen University Cancer Center; First Affiliated Hospital, Sun Yat-Sen University; The Third Affiliated Hospital, Sun Yat-Sen University) designed to determine the predicted performance of radiomics-based prediction model for identifying metastasis of each station lymph nodes by enhanced CT for preoperative noninvasive assessment of the lymph node status in patients with gastric cancer. The study includes the construction of CT radiomics-based prediction model and the validation of the prediction model.
This study proposes to establish a CT radiomics-based prediction model for identifying metastasis of each station lymph nodes in gastric cancer.
