In our TNAC cohort, a luminal androgen receptor (LAR) subtype, which is closely related to breast cancer of the apocrine type24, was the most common (29/73, 39.7%), followed by the mesenchymal stem-like (MSL) subtype (11/73, 15.1%), except for unstable (UNS) (Fig. 4A). Here, AR is linked to breast carcinoma.
