Kaplan–Meier survival plots for Overall Survival (OS) and Disease Specific Survival (DSS) related to PNI and other tumor characteristics. A-B: PNI status graded by H&E + IHC. C-D: lymph node metastasis clinical status. E-F: Patients with negative lymph node stratified by PNI status. Overall log-rank p-value for E is 0.145 and for F is 0.039. G: Tumor stage with patients stratified as T1 + T2 and T3 + T4. H: Worst pattern of invasion (POI). The number of patients at risk for each group at each time point is shown below the plots.
