The number of tumor-infiltrating immune cells was presented as the mean number ± standard error of the mean (M ± SE) in one field of view (FOV): CD8-TC = 59.61 ± 6.28, CD8-IF = 185.73 ± 11.13, CD4-TC = 28.60 ± 2.18, CD4-IF = 122.81 ± 7.64, CD3-TC = 33.73 ± 3.11, CD3-IF = 131.37 ± 9.56, TAN-TC = 52.27 ± 4.53, TAN-IF = 82.43 ± 8.29. This evidence concerns the gene CD8A and neoplasm.
