Currently, mainstream studies consider the EGJ to be a region that is separate from both the esophagus and the stomach.Our study aimed to construct a nomogram that accurately predicts the prognosis of postoperative patients with GCA at stages I–III based on a multivariate analysis. The C‐index and AUC values were both greater than 0.71, indicating favorable discrimination of the nomogram. Compared to the TNM staging system alone, the nomogram model had a higher accuracy, as shown by the AUC value. The DCA curve was used to analyze the clinical benefits of the model, and the results suggested that the nomogram had a high net clinical benefit. Further statistical analyses showed that the nomogram model had more advantages than the TNM staging system. The use of our nomogram model aligns with the current principles of personalized treatment. Finally, the applicability of the model was verified using an external population.Although chemotherapy is widely used in the treatment of GCA, our study found that it did not have a positive therapeutic effect on patients in this study.In the multifactor analysis, race, age, marital status, histological grade, T stage, and LODDS were determined to be independent prognostic factors. It has been widely reported that older age is a poor prognostic factor in cancer patients.Zhu et al. observed that White patients had the highest risk of GCA compared with that in the other ethnic groups, which is consistent with our findings.Compared with the study by Guo et al.,
