CD8A and neoplasm: In addition, there was a significant correlation with immune cell subtypes/IC markers, i.e., tumor infiltrating lymphocytes (TILs; rs = 0.368; p <0.001), CD3+ T cells (rs = 0.301; p <0.001), cytotoxic CD8+ T cells (rs = 0.348; p <0.001), CD56+ natural killer cells (NK cells; rs = 0.351; p <0.001) and CXCL9 protein expression (rs = 0.394; p <0.001).
