The mean stromal and intra-tumoral CD4 + and CD8 + T-cell density and their sum (CD4 + and CD8 +) were significantly higher in lymphocytic predominant BC samples (LPBC; stromal TIL > 50%) compared to non-LPBC tumors (Fig. 3d, e and Supplementary Table 2). The gene discussed is CD8A; the disease is breast cancer.
