CD8A and non-small cell lung carcinoma: The results showed that a high density of CD8+ TILs in the TN indicated a better OS (HR = 0.98; 95% CI, 0.97–1.0; p<0.001), PFS (HR = 0.55; 95% CI, 0.34–0.76; p<0.001), DFS (HR = 0.74; 95% CI, 0.57–0.91; p<0.001), RFS (HR = 0.37; 95% CI, 0.10–0.65; p = 0.008) and DSS (HR = 0.75; 95% CI, 0.52–0.98; p<0.001) for patients with NSCLC.
