The association between immune markers and tumor recurrence. a The percentage of low levels of CD8+ TIL was higher in patients with recurrence than in the control patients without recurrence. b The number of CD8+ TILs in IHC staining was significantly less in patients with recurrence than in control patients without any recurrence. Scale bar = 20 μm. c The expression of PD-L1 in IHC staining was not significantly different between patients with and without recurrence. Kaplan–Meier analyses demonstrated that the CD8+ TIL levels (d) significantly correlated with recurrence-free survival, whereas the PD-L1 expression (e) did not. IHC, immunohistochemistry; PD-L1, programmed death ligand 1; TILs, tumor-infiltrating lymphocytes
