 This study developed and validated a preoperative prediction model to estimate the Omental metastasis status of locally advanced gastric cancer, LAGC. The model combines radiomic scores and clinical features to improve the accuracy of predicting Omental metastasis status. This model has been shown to have high accuracy in predicting Omental metastasis status in LAGC, which can be used as a tool to guide clinicians in making decisions regarding surgery.
