METHODS： Medical records of 191 patients with total gastrectornies for adenocarcinorna of the cardia between 1995 and 2000 were reviewed. The clinicopathologic features associated with a positive margin were determined, and the predictors for survival were analyzed. RESULTS： The incidence of positive proximal margin was 8.4% （16/191）. The positive margins were associated with advanced diseases. The tumor size and the depth of tumor invasion were independent risk factors for a positive margin. The mean survival in the positive margin group was 33.9 mo as compared.with 62.4 mo in the negative group （P 〈 0.001）. However, the difference in survival lost significance in subgroup analysis according to stage. Multivariate analysis identified that a positive margin was not an independent prognostic factor for survival. CONCLUSION： A positive margin is more of an indication of advanced disease in patients with gastric adenocarcinoma of the cardia rather than an independent prognostic factor for survival.展开更多
