CD8A and neoplasm: When the group of patients was divided based on the median cell count per mm2 in the tumor area, higher pCR rates were observed in patients with high (above median) CD8+ infiltrate compared to low (below median) CD8+ infiltrate (pCR: 18.4% in high CD8+ infiltrate vs. 5.2% in low CD8+ infiltrate; p = 0.01).
