Results: A 1% cutpoint was confirmed as the appropriate threshold for AR positivity. Using this cutpoint 41% of 135 TNBC were AR+. AR+ TNBC occurred in older women, were larger, had lower mean proliferation rate and increased incidence of axillary metastasis than AR- TNBC. 76% of TNBC with apocrine morphology were AR+. 2018-06-08 · Summary of clinical and pathological features of AR positive TNBC. Using ≥1% AR immunoreactivity to define AR+TNBC, 41% of our study cohort were AR+. When compared to AR-TNBC, AR+TNBC were larger and more frequent in older women, showed a higher incidence of apocrine differentiation, a higher incidence of axillary lymph node metastasis, and lower proliferation rates. 2018-07-01 · With DFS data available for 521 TNBC patients, AR-positive tumors had a significant lower risk of relapse compared to the other TNBC subgroups (OR for DFS 0.44, p 0.002) .
Enhertu granted Priority Review in the US for the treatment of
Approximately one-third of TNBC expressed androgen receptor (AR) and evaluation of AR-positive TNBC primary tumors shows nuclear localization of AR, an indication of transcriptionally active receptors. Growing studies demonstrated that Androgen Receptor (AR) has an oncogenic role for the patients with AR-positive Triple Negative Breast Cancer (TNBC). AR antagonists in therapy, such as bicalutamide, completely binds to the AR, increasing AR degradation, thus are investigated for the efficacy of the treatment of patients with AR-positive TNBC in the study. e12102 Background: Increased rates of locoregional recurrence have been observed in TNBC despite chemotherapy and radiation (RT).

TNBC cells derived from these luminal AR + tumors have high frequency phosphatidylinositol-4,5-bisphosphate 3-kinase
Luteolin represses the proliferation of AR-positive TNBCs The expression level of the AR in four TNBC cell lines (MDA-MB-231, MDA-MB-468, BT-20, and BT-549) was assessed by western blotting analysis. A higher level of AR expression was observed in the BT-20 and BT-549 cells compared with MDA-MB-231 and MDA-MB-468 cells (Fig. 1 B).
Patients with ER-positive and/or progesterone receptor-positive primary tumors were eligible if they had advanced TNBC. Nearly 80% of the evaluable samples expressed nuclear AR >0%, and more than
As a greater understanding of triple-negative breast cancer (TNBC) heterogeneity develops over time, combinations of PD-1/PD-L1 plus PARP inhibitors, androgen receptor (AR) targeted agents, and PI3K/AKT/mTOR pathway inhibitors are undergoing evaluation by investigators in the field. “We’ve learned that triple-negative breast cancer has multiple different subtypes,” Kari B. Wisinski, MD, said during a presentation at the 22nd Annual Lynn Sage Breast Cancer Symposium, a virtual event. 1
Further, AR inhibitors have demonstrated antitumor activity in preclinical and early clinical studies.

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.
AR-positive TNBC may represent a breast cancer subtype with unique features that may b … The AR is expressed in normal breast tissue, and expression decreases with … In this study we determine the appropriate threshold of AR immunoreactivity to define AR positive (AR+) TNBC, describe the clinicopathologic features of AR+ TNBC, and discuss the utility of AR positivity as a prognostic and predictive marker in TNBC. 2018-06-08 2013-09-18 However, its prognostic value remains controversial in triple negative breast cancer (TNBC). Here we present a meta-analysis to investigate the correlation between AR expression and TNBC prognosis. Results: Thirteen relevant studies with 2826 TNBC patients were included. AR positive rate was 24.4%. 2018-07-01 2014-08-08 Investigators assessed the outcomes of 118 patients with AR-positive locally advanced or metastatic TNBC who received enzalutamide 160 mg once daily. Examples of these tailored approaches include poly(ADP-ribose) polymerase inhibitors for BRCA-mutated TNBC, antiandrogens for androgen receptor (AR)-positive TNBC, fibroblast growth factor receptor (FGFR) inhibitors for TNBC harboring FGFR amplifications, and gamma-secretase inhibitors for TNBC with mutations in the PEST domain of NOTCH proteins.

The aim of this study was to evaluate the expression of the AR, E-cadherin and Ki-67 in relation to histological type, time to relapse and overall survival (OS). Immunohistochemistry (IHC) was carried out on formalin-fixed AR biomarker discovery Treat to progression AR testing IHC results reported as: “Positive” (AR > 0%) “Negative” (AR = 0%) • AR “positive” TNBC* • ECOG-PS ≤ 1 • Sufficient tissue to enable biomarker discovery • No CNS metastases • Any number of prior therapies permissible • Evaluable bone-only disease allowed Stage 1 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 · At the 10% cutpoint of AR positive, AR expression was associated with the high pathological grade of TNBC patients . Thus, our results revealed that AR immunoreactivity in at least 1% of tumor cell was considered the most appropriate threshold to define AR positivity. 2020-01-01 · AR can both stimulate proliferation and dedifferentiation and induce apoptosis and cell death, depending on the simultaneously activated signaling pathways. Although early studies have suggested a negative prognostic effect of AR in TNBC, the latest data have reaffirmed that patients with AR-positive TBNC have a more favorable outcome.
Met and its ligand HGF are associated with clinical outcome in
43 , 44 In this study, of 424 patients with ER/PR‐negative BC, 12% was AR‐positive. The androgen receptor (AR) is a promising therapeutic target for a subset of triple-negative breast cancers (TNBCs) in which AR is expressed. However, the mechanistic action of AR and the degree to which primary and metastatic tumors depend on AR, both before and after conventional treatment, remain to be defined. We discuss preclinical and clinical data for AR+ TNBC, the difficulties in Although AR expression is often associated with a favorable prognosis in ERα-positive (ERα+) BC, many findings suggest that, in some instances, high levels of AR can contribute to the therapy-resistance. Again, in ERα negative BC (ERα-), AR is mainly expressed in tumors with apocrine differentiation and a lower Nottingham grade.
