2020-11-19 · Based on the androgen receptor (AR) expression, triple-negative breast cancer (TNBC) can be subdivided into AR-positive TNBC and AR-negative TNBC, also known as quadruple-negative breast cancer (QNBC). QNBC characterization and treatment is fraught with many challenges. two AR antibodies, AR441 (Dako, Carpinteria, CA) and SP107 (Ventana, Tucson, AZ), wereoptimized for testing breastcancer tissue.22 IHC results using SP107 determined eligibility and were used to report study-related outcomes. Investigators were informed only that a patient was AR positive or negative. 2019-03-14 · Breast cancer (BC) is still characterized by high morbidity and mortality. A specific BC subtype named triple negative BC (TNBC) lacks estrogen and progesterone receptors (ER and PR, respectively 2020-02-11 · Increased rates of locoregional recurrence (LR) have been observed in triple negative breast cancer (TNBC) despite multimodality therapy, including radiation (RT).

AR seems to play a major role in TNBC carcinogenesis. However, its impact on patient prognosis and its predictive role in patients with TNBC are still controversial.
So even though you aren’t receiving hormonal therapy, you’re likely getting treatment that’s very effective for hormone-receptor-negative breast cancer. Breast cancers are ER-positive, HER2-positive, or triple negative. The type of breast cancer you have determines the type of medication you take. Learn more from experts at WebMD. Triple-negative breast cancer cells don’t have estrogen or progesterone receptors and also don’t make too much of the protein called HER2. These cancers tend to be more common in women younger than 40 years of age, who are African-American, or who have a mutation in the BRCA 1 gene.

More and more evidences demonstrate that androgen receptor (AR), epidermal growth factor receptor (EGFR), and breast cancer susceptibility gene 1 (BRCA1) have unique clinical implications for targeted therapy or prognosis in triple-negative breast cancer (TNBC). The androgen receptor (AR) is present in approximately 80% of invasive breast cancer patients and in up to 30% of patients with triple-negative breast cancer (TNBC). Therefore, our aim was to investigate the targeting of AR as a possible hormonal approach to the treatment of TNBC.

Based on the androgen receptor (AR) expression, triple-negative breast cancer (TNBC) can be subdivided into AR-positive TNBC and AR-negative TNBC, also known as In this study, we investigated the high‐risk group of breast cancer with the triple‐negative phenotype (estrogen receptor‐negative, progesterone receptor‐negative, and HER2‐negative) that lacks the benefit of specific therapy that targets these proteins to characterize and identify additional prognostic markers that can identify tumors with more aggressive behavior.

AB - Background: The significance of androgen receptor (AR) expression in triple-negative breast cancer (TNBC) is unclear, and published studies so far have been inconclusive. Over 275,000 patients will be diagnosed with breast cancer in 2020. Approximately 15% (over 40,000) will be triple negative breast cancer which is a type of breast cancer that lacks the 3 receptors (or markers) found in breast cancer – Estrogen Receptor, Progesterone Receptor, and HER2.
