CD8A and neoplasm: Table 4 shows the significant correlations between tumour-infiltrating (intratumoural, stromal) lymphocytes, respectively (TILs: rho = 0.601, p < 0.001, and rho = 0.641, p < 0.001; CD4+ T cells (stroma): rho = 0.468, p = 0.006; CD8+ T cells: rho = 0.446, p = 0.009, and rho = 0.471, p = 0.006), and grade of pathological response (grade 1 (no pathological response) to grade 5 (pCR)) in the breast cancers following 8 cycles of NAC.
