CD8A and neoplasm: Patients (33/196; 16.8%) with high tumor PD-L2 had a high density of CD8+ TILs, and 105 of 437 (24.0%) patients with low tumor PD-L2 had a high number of CD8+ TILs, indicating that tumor PD-L2 expression was inversely correlated with intratumoral CD8+ TILs (p = 0.048, Pearson's chi-squared test).
