CD8A and neoplasm: The percentages of infiltrating CD8+, PD1+, and PD1+CD8+ T cells, as well as the ratio of PD1+CD8+/CD8+ T cells in the whole tumor, were marginally or statistically higher in preneoadjuvant therapy (pre‐NAT) samples from pCR patients than in non‐pCR patients (P = 0.096, P = 0.069, P = 0.013, and P = 0.012, respectively) (Table 1).
