Cell counts of CD8+/PD1− TILs, not CD8+/PD1+ TILs, were significantly related with E-Cad expression percentile, and there were 14 CD8+/PD1− TILs in BC patients with a positive E-Cad expression (Figure 2(a)) and 6 CD8+/PD1− TILs in BC patients with a negative E-Cad expression (p < 0.05, Figure 2(b), Table 5). This evidence concerns the gene CAD and breast cancer.
