Figure 5. Tumors with higher PD-L1 expression were associated with a poor clinical outcome in the Sanbo cohort (p =0.017, (A). Tumor-infiltrating neutrophils (TINs) were significantly increased in tumors with PD-L1 positivity (p = 0.005, (B). Spearman correlation between TINs and PD-L1 mRNA levels showed that PD-L1 transcript levels were significantly positive with TINs in TCGA (p < 0.001, (C) and CGGA cohorts (p < 0.001, (D).
