In their work, the densities of CD8+, DC-LAMP+, and NKp46+ TILs (markers of cytotoxic T cells, mature dendritic cells, and natural killer cells, respectively) were positively correlated between primary CRC and RCC tumors and corresponding lung metastases (r = 0.656 to 0.693 for CRC and 0.547 to 0.817 for RCC). This evidence concerns the gene CD8A and colorectal carcinoma.
