CD8A and neoplasm: Our results showed that, of all tumor-infiltrating immune cells (TIICs), the abundance of B-cell memory, T-cell CD8 memory, and T-cell CD4 memory resting significantly decreased in the high-risk group, which was consistent with the GO enrichment result that the immune process was inhibited, indicating there existed immune escape caused by T-cell depletion in the high-risk group.
