Abstract

Objective: The postoperative survival rates of patients with gastric cancer at different stages treated at the National Cancer Center (NCC) of China have not been reported. Therefore, we evaluated the survival of patients with gastric cancer who underwent surgery at the NCC from 2011 to 2018 to provide baseline information for further studies.

Methods: We identified 7,301 patients with primary gastric carcinoma who underwent surgery at the NCC between January 2011 and May 2018; among these, 5,008 patients were enrolled in this study. Follow up was completed on April 30, 2020. We analyzed the 5-year survival according to the stage, sex, age, and other clinicopathological features.

Results: Five-year survival rates of patients with pTNM stages IA, IB, IIA, IIB, IIIA, IIIB, IIIC, and IV treated at the NCC were 94.9%, 91.8%, 86.5%, 76.1%, 61.1%, 44.2%, 29.7%, and 8.1%, respectively, which were similar to those reported in Japan during the same period. Five-year survival rates of patients with ypTNM stages I, II, III, and IV were 93.1%, 63.2%, 27.2%, and 0.0%, respectively. In multivariable analysis, age, signet ring cell carcinoma, adjuvant chemotherapy, and degree of differentiation were revealed as important prognostic factors.

Conclusion: The survival rates of patients with gastric cancer treated at the NCC have been significantly improved, reaching the levels of Japan in the same period.
