ABSTRACT
Purpose : We evaluated the influence of the changes regarding the classification of gastric cancer in the 7th UICC TNM classification compared to 6th UICC TNM classification. Materials and Methods : Between January 1990 and August 2007, 339 patients with gastric cancer who had undergone gastric surgery with D2 and with 15 or more lymph nodes retrieved were studied retrospectively. Results : According to the 7th UICC stage, the 5-year cumulative survival rates of stage IA, IB, IIA, IIB, IIIA, IIIB, IIIC, IV were 92.2%, 91.2%, 85.2%, 82.4%, 49.7%, 36.9%, 24.7%, and 0%, respectively.(P<0.001) In multivariate analysis, age(60 year below and above), 6th TNM stage, 7th TNM stage have survival significance. Significant sectional differences were higher at 6th edition(60%) than 7th edition(28.6%). Conclusion : The 6th UICC classification system has better survival significance compared to 7th edition except stage IV gastric cancer. In the era of 7th edition, it is better to perform peritoneal cytology during advanced gastric cancer surgery to have exact stage.
