Figure 5.

(A) Bar chart showing the quantity of cases of consistent/inconsistent expression of PD‐L1/CD8⁺ TILs between PLs and LNs; (B) Kaplan–Meier survival curves of patients with LN⁺ (A–C), consistent expression of PD‐L1 (between PLs and LNs) (D–F), inconsistent expression of PD‐L1 (G–I), consistent expression of CD8⁺ TILs density (J–L), inconsistent expression of CD8⁺ TILs density (M–O). Other than patients with inconsistent expression of PD‐L1, CD8^high TILs was associated with better OS than CD8^low in the rest four groups. It showed no correlation between PD‐L1 expression and OS among all the five groups. Notes: LN⁺ refers to metastatic lymph nodes (patients staged as p‐TxN1‐3Mx). PLs, primary lesions; LNs, lymph nodes.
