Embodiment 1
[0031] The present invention first establishes a domestic multi-center, large sample, complete clinical database of clinical pathological data and follow-up data for gastric cancer, and selects 6753 patients who meet the requirements from the basic data of 10213 Chinese gastric cancer patients as the basis for constructing the prediction model It is divided into a model training set and two external validation sets for prediction and calculation of prediction accuracy. Finally, the predicted patient survival is compared with the actual survival of the patient to evaluate the prediction performance. The detailed results are as follows:
[0032] 1. Through conditional screening of 10,213 gastric cancer patients, gastric remnant cancer, multiple primary tumors, patients with preoperative chemotherapy, patients with distant metastases, patients with early tumors, patients with non-D2 radical resection, patients with non-R0 resection, and perioperative period were excluded.
