摘　　要：The factors influencing the long-term survival of patients with proximal gastric cancer (PGC) after curative resection were investigated. Data from 171 patients who underwent curative resection for PGC were retrospectively analyzed. The patients were grouped according to the clinicopathological factors and operative procedures. The tumor depth (T stage) and lymph node metastasis (pN stage) were graded according to the fifth edition of TNM Staging System published by UICC in 1997. The metastatic lymph node ratio (MLR) was divided into four levels: 0%, 30%. The data of survival rate were analyzed by Kaplan-Meier method (log-rank test) and Cox regression model. The 5-year overall survival rate of 171 patients was 37.32%. The univariate analysis demonstrated that the survival time of the postoperative patients with PGC was related to tumor size (χ2=4.57, P=0.0325), gross type (χ2=21.38, P30% (χ2=13.34, P=0.0003), TNM Ⅲ (χ2=14.05, P=0.0002) or TNM Ⅳ stage (χ2=4.37, P=0.0366); and combining splenectomy was beneficial to the cases of T3 (χ2=5.68, P=0.0171) or MLR >30% (χ2=6.11, P=0.0134). It was concluded that MLR, pN stage, TNM stage, T stage, and gross type had advantages in providing a precise prognostic evaluation for patients undergoing curative resection for PGC, in which MLR was the most valuable index. TG and combining splenectomy were useful to improve the prognosis to patients with PGC of TNM Ⅲ/Ⅲ stage, serosa invasion, or extensive regional lymph node metastasis.The factors influencing the long-term survival of patients with proximal gastric cancer (PGC) after curative resection were investigated.
