CD8A and non-small cell lung carcinoma: The results of the analysis showed that high density of TILs indicated favorable OS (HR = 0.80, 0.70–0.89) and PFS (HR = 0.73, 0.61–0.85) in patients with NSCLC; a high density of CD3+, CD4+, CD8+ TILs indicated high DSS and a high density of CD20+ TILs indicated favorable OS (HR = 0.65, 0.36–0.94).
