Androgen receptor (AR) is a member of the steroid receptor superfamily which is expressed in more than 70% of breast cancer and in about 15% of TNBC [ 3, 4, 5 ]. Positive expression of AR in TNBC patients was reported to be associated with worse clinical outcomes, indicating that AR blockade might be a potential endocrine therapy for TNBC [ 6 ].

Treatment with abiraterone acetate plus prednisone was beneficial for some patients with molecular apocrine breast cancer, a subtype that expresses androgen receptor (AR), but not estrogen Many people still believe that breast cancer, even hormone-positive disease, is essentially cured after five years; this can lead to misunderstandings in families. Loved ones who don't understand late recurrence may downplay your feelings, or criticize you when you think "brain tumor" each time you get a headache.

About 80% of all breast cancers are “ER-positive.” That means the cancer cells grow in response to the hormone estrogen. About 65% of these are also “PR-positive.” They grow in response to another

The role of AR in breast cancer carcinogenesis is complex. Without its ligand, AR is found in the cytoplasm kept inactive by a heterocomplex with heat-shock proteins and a chaperone complex (HSP-70, HSP-90). Circulating androgens bind to the C-terminal ligand-binding domain leading to a conformational change which allows AR dimerization.
