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 Inclusion Criteria: - Age: 18-70 years old, female - Eastern Cooperative Oncology Group (ECOG) 0 or 1 - Confirmed by pathology or organizing cytology AR positive(IHC：≧10%)triple negative breast cancer - For the first time recurrence or newly diagnosed advanced breast cancer,Disease-free survival time 12 months above - Measurable disease per RECIST version 1.1,or immeasurably lesions bone 2020-09-07 AR is expressed in >60% of BC and in up to 90% of ERα-positive tumors. Multiple studies suggest that AR is associated with a favorable prognosis. However, AR overexpression and, in particular, the high AR:ER ratio, seem to be involved in resistance to hormonal treatment. 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.

When the hormones estrogen and progesterone attach to these receptors, they fuel the cancer growth. Cancers are called hormone receptor-positive or hormone receptor-negative based on whether or not they have these receptors (proteins). Androgen Triggers the Pro-Migratory CXCL12/CXCR4 Axis in AR-Positive Breast Cancer Cell Lines: Underlying Mechanism and Possible Implications for the Use of Aromatase Inhibitors in Breast Cancer.

Hormone receptor-positive (or hormone-positive) breast cancer cells have either estrogen (ER) or progesterone (PR) receptors or both. These breast cancers can be treated with hormone therapy drugs that lower estrogen levels or block estrogen receptors.

(2017) 44:66–84. doi: 10.1159/000484584 β2-AR is highly expressed in Her2-positive breast cancer. In our previous study, we demonstrate that enforced overexpression of Her2 in breast cancer cells upregulates the expression of β2-AR at both mRNA and protein levels [], raised questions as to how the expression of β2-AR is modulated by Her2 in breast cancer. tumours: importance of immune response.

Breast Carcinoma + AR is altered in 1.82% of breast carcinoma patients [ 4 ]. AR Positive is an inclusion criterion in 18 clinical trials for breast carcinoma, of which 13 are open and 5 are closed. 2021-01-18 · The role of the androgen receptor (AR) in estrogen receptor (ER)-α-positive breast cancer is controversial, constraining implementation of AR-directed therapies.

2021-01-18 · The role of the androgen receptor (AR) in estrogen receptor (ER)-α-positive breast cancer is controversial, constraining implementation of AR-directed therapies. 2019-02-22 · The androgen receptor (AR) is an emerging prognostic marker and therapeutic target in breast cancer. AR is expressed in 60–80% of breast cancers, with higher prevalence among estrogen receptor-positive (ER+) tumors.

However, AR overexpression and, in particular, the high AR:ER ratio, seem to be involved in resistance to hormonal treatment. Conclusions: The AR is expressed in normal breast tissue, and expression decreases with advancement to DCIS and invasive cancer.

Expression of AR has been observed in 70%–80% of all breast cancer [16-18], and HR‐positive (+) breast cancer exhibits significantly higher AR expression than HR‐negative (−) breast cancer [17, 18]. Moreover, AR expression seems to be associated with favorable clinical outcome in estrogen receptor (ER) + breast cancer [19, 20].
