For breast cancer‐specific survival, four markers were associated with OS in the tumor compartment (EpCAM, P = 0.0072; ER, P = 0.037; Ki‐67, P = 0.039; STING, P = 0.043) and four in the stromal compartment (CD8, P = 0.024; CD25, P = 0.013; CD56, P = 0.018; ER, P = 0.018; Figs S5 and S6). Here, NCAM1 is linked to breast carcinoma.
