Figure 3

In patients without lymph node metastasis, the tumoral PD-L1 expression (≥1%, 5%, 10%, 20%, or 30% as cut-off value) was associated with improved DFS (P=0.026, 0.024, 0.015, 0.003, or 0.005) A-E. and OS (P=0.019, 0.015, 0.016, 0.007 or 0.011) F-J. However, in patients with lymph node metastasis, the tumoral PD-L1 expression (≥1%, 5%, 10%, 20%or 30% as cut-off value) was not associated with DFS (P=0.973, 0.996, 0.622, 0.881 or 0.254) K-O. and OS (P=0.864, 0.943, 0.610, 0.675, or 0.126) P-T.
