Comparison of the survival curves of AEG patients according to the N classification of the TNM staging system and the PLNR. A. By using the N classification of TNM staging, the prognoses of N2 and N3 patients were very similar until 2.5 years after surgery. The 2.5-year survival rates of patients with N0, N1, N2 and N3 were 90.7%, 75.0％, 52.4％ and 51.9％, respectively. B. By using the PLNR cut-off values (PLNR 0, PLNR 0 - < 0.1, PLNR 0.1 - < 0.2 and PLNR ≥ 0.2), patients were more appropriately classified into four groups compared to using the N classification of TNM staging. The 2.5-year survival rates of patients with PLNR 0, PLNR 0 - < 0.1, PLNR 0.1 - < 0.2 and PLNR ≥ 0.2 were 90.7％, 66.7％, 57.1％ and 35.7％, respectively
