The role of androgen receptor varies depending on subtype. AR confers good prognosis in estrogen receptor positive (ER+) breast cancer, but its role in ER-negative (ER−) breast cancer is unclear. Combined Androgen and Estrogen Receptor Status in Breast Cancer: Treatment Prediction and AR confers good prognosis in estrogen receptor positive (E..

Triple negative breast tumors: 6.6 - 75%; range due to variable cutoffs, source of antibody and methodologies, highest expression in luminal androgen receptor subtype (Breast Cancer Res Treat 2011;130:477, Clin Cancer Res 2011;17:1867, Clin Cancer Res 2013;19:5505, Clin Adv Hematol Oncol 2016;14:186) An international study led by Australian scientists has shown for the first time that the androgen receptor (AR) is a tumor suppressor in estrogen receptor-positive (ER+) metastatic breast cancer, including in endocrine therapy resistance, which supports the use of an AR agonist-based treatment strategy. The study, published in Clinical Cancer Research, tested tumors from patients with ER/progesterone receptor (PgR)-negative advanced breast cancer for AR by IHC (>10 percent nuclear staining considered positive). If either the primary or a metastatic site was positive, patients were then eligible to receive Casodex at a dose of 150 mg daily.

Patients and Methods Tumors were tested for AR with an immunohistochemistry assayoptimized for breast cancer; nuclear ARstaining .0% wasconsidered positive. Patientsreceived enzalutamide 160 mg once per dayuntil 2018-06-08 Tiffany A. Traina, MD. In findings from the phase II MDV3100-11 study published in theJournal of Clinical Oncology, enzalutamide demonstrated early signs of efficacy in patients with androgen receptor (AR)-positive triple-negative breast cancer (TNBC).. The single-arm, 2-stage study enrolled 118 patients, with 78 evaluable for response. Androgen receptor (AR, a member of the steroid hormone receptor family) status has become increasingly important as both a prognostic marker and potential therapeutic target in breast cancer. AR is expressed in up to 90% of estrogen receptor (ER) positive breast cancer, and to a lesser degree, human epidermal growth factor 2 (HER2) amplified tumors. 2019-10-29 Androgen Receptor-Positive Triple Negative Breast Cancer: A Unique Breast Cancer Subtype Lee J.

Conclusions: The AR is expressed in normal breast tissue, and expression decreases with advancement to DCIS and invasive cancer. AR-positive TNBC was more common in older patients and had a higher propensity for LN metastases. AR-positive TNBC may represent a breast cancer subtype with unique features that may be amenable to treatment with alternative targeted therapies. Androgen Receptor Modulator in ER-Positive/AR-Positive Breast Cancer By: Vanessa A. Carter, BS Posted: Thursday, January 21, 2021 Carlo Palmieri, PhD , of the Clatterbridge Cancer Center NHS Foundation Trust, Liverpool, and colleagues devised a study to determine the efficacy of enobosarm in patients with advanced estrogen receptor (ER)-positive/androgen receptor (AR)-positive breast cancer.
