The luminal androgen receptor (LAR) subtype of TNBC is characterized by chemoresistance, yet a lower risk of disease recurrence. 67 It was hypothesized the AR inhibition would result in antitumor activity in this subtype of TNBC, a principle that was proved in the TBCRC001 phase II trial of bicalutamide in which 26 patients with AR positive, ER negative metastatic breast cancer had a 19%
AR-positive TNBC may represent a breast cancer subtype with unique features that may be amenable to treatment with alternative targeted therapies. The significance of androgen receptor (AR) expression in triple-negative breast cancer (TNBC) is unclear, and published studies so far have been inconclusi

II. Triple-negative breast cancer (sometimes abbreviated TNBC) is any breast cancer that does not express the genes for estrogen receptor (ER), progesterone receptor (PR) and HER2/neu. This makes it more difficult to treat since most hormone therapies target one of the three receptors, so triple-negative cancers often require combination therapies. In addition, recent studies reported that anti-androgen therapy shows preclinical efficacy in androgen-receptor (AR)-positive TNBC cells. Here we examined the effect of palbociclib in combination with an anti-androgen enzalutamide in TNBC cells. 2019-03-01 AR-Positive TNBC (N=340) AR-Neg TNBC (QNBC) (N=1612) AR-unknown (N=119) Breast Liver Lymph Nodes Skin Lung Connective Tissue Other Patient Age Average 59.2 54.9 p<0.0001 Interquartile Range 52-68 47-63 Although TNBC lacks hormone receptors traditionally associated with breast cancer, emerging data suggest that AR plays a strong role in the Patients with ER-positive and/or progesterone receptor-positive primary tumors were eligible if they had advanced TNBC.

But research is now focusing on the androgen receptor (AR) in a subset of patients with TNBC who are AR-positive. “There is compelling evidence that the androgen pathway may deliver the next target for drug development,” Traina said, referring to a phase 2 safety and efficacy study evaluating enzalutamide (Xtandi) in this subpopulation (NCT01889238).
