Abstract
Purpose: The most important prognostic factors in gastric cancer is the depth of invasion of the primary tumor and lymph node metastasis. The nodal staging of the 5th edition of the Union Internationale Contrala Cancrums (UICC) TNM classification in 1997 was changed based on the number of metastatic lymph node. We attempted to evaluate the prognostic significance of N2 group metastasis in pT3pN1 gastric cancer patients by comparing two different nodal staging systems. Materials and Methods: A retrospective analysis was made for 352 gastric cancer patients who underwent curative resection, including D2 dissection, from 1991 to 1997 at Asan Medical Center. A clinicopathologic comparison between two groups by using a nodal staging systems was summarized into a table. Cumulative survival rates were calculated by using the Kaplan-Meier method. The difference between the two groups was evaluated by using the log rank test with SPSS 11.5 for Windows Results: There were no statistical differences in clinicopathologic factors. However, there was a significant difference in survival rate between the two groups (P=0.0009). This suggests that N2 group metastasis in pT3pN1 gastric cancer patients has a clinical significance for predicting prognosis. Conclusion: Our results suggest a possibility of prognostic significance of N2 group metastasis. Therefore, anatomical location of the lymph node should be described.
