Abstract

Many issues of middle-third gastric cancer need to be address for obtaining preferably clinical treatment. The objective of this retrospective study was to analyze clinicopathologic characteristics and results of surgery for 113 middle-third gastric cancer patients admitted to our hospital. Retrospective cohort analyses of clinicopathologic data and postoperative prognosis of 113 middle-third gastric cancer patients who underwent curative resection between January 1997 and December 2003 were reviewed. Compared with lower-third gastric cancer patients, middle-third gastric cancer patients had significantly lower 5-year survival rate (P < 0.001) and higher recurrence rate (P < 0.001). With the Cox proportional hazards model analysis, the types of gastrectomy (hazard ratio (HR) = 0.495, P = 0.012) and ratio between metastatic and dissected lymph nodes (RML) (HR = 1.681, P < 0.001) were identified as the independent predictors of overall survival (OS) of middle-third gastric cancer patients. Besides, only RML (HR = 3.026, P < 0.001) was an independent predictor of recurrence for middle-third gastric cancer patients after surgery identified using the logistic regression analysis. The prognosis of middle-third gastric cancer was significantly worse than lower-third gastric cancer. RML was a key indicator for OS and recurrence of middle-third gastric cancer.
