Further, AR inhibitors have demonstrated antitumor activity in preclinical and early clinical studies. Trippelnegativ bröstcancer (TNBC) innebär att tumören saknar receptorer (mottagarmolekyler) för de kvinnliga könshormonerna östrogen/progesteron och HER2, ett protein på cellers yta som stimulerar celltillväxt. Därför kan tumören inte behandlas med målinriktad behandling som antiöstrogen, aromatashämmare eller HER2 terapi. Request PDF | On May 20, 2015, Maximiliano C Kneubil and others published Prognostic factors correlation with androgen receptor (AR) in triple negative breast cancer (TNBC). | Find, read and cite 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 2018-01-31 · However, molecular assays of TNBC have identified distinct subsets of TNBC that may inform therapeutic strategies. One such subset expresses the androgen receptor (AR), and recent trials have shown that patients with AR-positive TNBC had modest response to the AR inhibitors abiraterone acetate ( Ann Oncol 2016; 27:812 ) and bicalutamide ( Clin Cancer Res 2013; 19:5505 ).

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.

Using AR + TNBC cell line and xenograft models we evaluated the effectiveness of PI3K inhibitors, used alone or in combination with an AR antagonist, on tumor cell growth and viability. Results: PIK3CA kinase mutations were highly clonal, more frequent in AR + vs. AR- TNBC (40% vs. 4%), and often associated with concurrent amplification of the PIK3CA locus. 2014-08-08 · Using AR + TNBC cell line and xenograft models we evaluated the effectiveness of PI3K inhibitors, used alone or in combination with an AR antagonist, on tumor cell growth and viability.

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.

Evidence from ongoing clinical trials suggests that patients with AR-positive luminal-type (LAR) TNBC may benefit from anti-androgen drugs that are used to treat prostate cancer. BCRF is investing $10 million as part of its Drug Research Collaborative to advance our understanding of LAR TNBC and accelerate targeted therapies to the clinic.

The first proof‐of‐concept trial established activity of the AR antagonist, bicalutamide, in patients with advanced AR‐positive TNBC. 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.
