Summary:Background We investigated the superiority of the 8th edition of the tumor-node-metastasis (TNM) system for patients in China with gastric cancer. Methods The survival outcomes of 1663 patients with gastric cancer undergoing radical resection were analyzed. Results In the 8th edition system, homogeneous 5-year survival rates among different pathological TNM (pTNM) categories belonging to the same stage were observed. However, in the 7th edition system, the differences of 5-year survival rate among pTNM categories belonging to the same stage were observed in stages IIB ( P  = 0.010), IIIB ( P  = 0.004), and IIIC ( P
