High PD-L1⁺ lymphatic and PD-1⁺ CD8⁺ T cell infiltration correlate with poor CCa prognosis

(A and B) Correlation of PD-1⁺ CD8⁺ T cells (A) and PD-L1⁺ lymphatics (B) to overall survival (OS) and disease-free survival (DFS). (C−E) The OS and DFS of CCa patients with lower versus higher expression of PD-1⁺ CD8⁺ T cells (C), or PD-L1⁺ lymphatics (D), or PD-1⁺ CD8⁺ T cells plus PD-L1⁺ lymphatics (E) were estimated using Kaplan-Meier curves. The median expression was used as the cut-off value. ∗∗∗p < 0.001.
