Each tumor was scored at three mean cutoff levels (< or ≥10%, 15%, or 20% of 100 tumor cells) for the Ki-67 labeling index (LI), whereas mean absolute number of CD8 immunopositive cells in ten high-power fields (HPF = 400×) was expressed at three cutoff levels (< or ≥10, 15, or 20 cells per HPF). Here, CD8A is linked to neoplasm.
