At first glance, it would seem triple-positive breast cancer would offer the best prognosis, followed by tumors that are ER-positive or HER2-positive, with triple-negative tumors having the worst outcomes. Androgen receptor (AR) is a member of the steroid receptor superfamily which is expressed in more than 70% of breast cancer and in about 15% of TNBC [ 3, 4, 5 ]. Positive expression of AR in TNBC patients was reported to be associated with worse clinical outcomes, indicating that AR blockade might be a potential endocrine therapy for TNBC [ 6 ]. 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].

7. Retrospective pooled analysis of AR mRNA expression in breast cancer The magnitude and direction of association between AR expression and clinical outcome in both ER-positive and ER-negative breast cancer is unclear. We report a systematic review and a meta-analysis of the influence of AR expression on clinical outcomes in early breast cancer. 2018-07-01 · A single study exploring the prevalence of AR expression in 88 patients with inflammatory breast cancer (IBC) showed that only 5 of the 17 TNBC were AR-positive. Interestingly, women with AR-negative TNBC had inferior 5-year survival rates compared with the AR-positive TNBC and the other histologic subgroups (p < 0.03) [53] .
