Triple negative breast cancer (TNBC) is an aggressive breast cancer subtype that lacks estrogen receptor, progesterone receptor, and human epidermal growth factor receptor 2 (HER2) amplification. Due to the absence of these receptors, TNBC does not respond to traditional endocrine or HER2-targeted therapies that improve patient prognosis in other breast cancer subtypes. TNBC has a poor prognosis, and currently, there are no effective targeted therapies. Some TNBC tumors express androgen receptor (AR) and may benefit from AR-targeted therapies. Here, we review the literature on AR in TNBC and propose that TNBC be further sub-classified as either AR+ TNBC or quadruple negative breast cancer since targeting AR may represent a viable therapeutic option for a subset of TNBC.
三阴性乳腺癌(TNBC)是一种侵袭性乳腺癌亚型,缺乏雌激素受体、孕激素受体以及人表皮生长因子受体2(HER2)扩增。由于缺乏这些受体,TNBC对传统内分泌疗法或HER2靶向疗法无反应,而这些疗法可改善其他乳腺癌亚型患者的预后。TNBC预后较差,目前尚无有效的靶向治疗方法。一些TNBC肿瘤表达雄激素受体(AR),可能从AR靶向治疗中获益。在此,我们综述了关于TNBC中AR的文献,并建议将TNBC进一步细分为AR阳性TNBC或四阴性乳腺癌,因为靶向AR可能是一部分TNBC患者可行的治疗选择。
