Fig. 3From: A homogenized approach to classify advanced gastric cancer patients with limited and adequate number of pathologically examined lymph nodesKaplan–Meier analysis showing the detailed survival differences of the study cohort using the different TNM classifications. Illustration of the overall survival of advanced gastric cancer patients using the a 8th AJCC TNM classification, b 8th AJCC TNM classification stratified into Limited (< 16 eLNs) and Adequate (≥ 16 eLNs) eLN cohort, and c the TN′M classification, which consists of patients re-classified using the N′ classification and it can be found to demonstrate a better demarcation between patients with less advanced disease (IB′) in contrast to those with more advanced disease. Note: the horizontal broken lines demonstrate the survival differences between c and a and simultaneously the rationale for formulating c from b.
