Abstrakt		The 5th edition of TNM classification (1997) grades lymph node involvement in gastric cancer by the number of metastatic lymph nodes. Their prognostic significance as defined by the new (5th ed. 1997) and old (4th ed. 1987) TNM classification was evaluated and survival in pN categories between both versions was compared. It was demonstrated in our analysis that comparison of old and new TNM system is possible. Categories pN1 and pN2 contain patients selected by different criteria in both versions of TNM classification but with similar survival probabilities. Anatomic location of lymph nodes as described in the 4th ed. and number of involved nodes in the 5th ed. have about the same prognostic value in the category pN1 and pN2. The advantage of the 5th ed. is the identification of a group of patients (pN3, >15 involved lymph nodes) with significantly poor prognosis which includes in our series 15% of R0 resected patients with lymph-node metastases.
