Abstract: The present disclosure provides a construction method of a risk prediction model for a prognosis of gastric cancer, and belongs to the technical field of biomedicine. In the present disclosure, from the perspective of bioinformatics analysis, it is predicted that gastric cancer exosomes carry circRNAs. Markers regulating the occurrence and development of gastric cancer are selected by combining the circRNAs with an RNA binding protein (RBP). A predictive marker for the prognosis of gastric cancer is an RPB gene, including one or more of AUH, HNRNPC, HNRNPD, U2AF2, and FXR1. The risk prediction model constructed based on the predictive marker can quickly and accurately predict the prognosis of patients with gastric cancer.
