The advantages of oophorectomy, adrenalectomy and hypophysectomy in women with advanced BC have been demonstrated many years ago, and currently ET consist of(1) ovarian function suppression(OFS), usually obtained using gonadotropinreleasing hormone agonists(Gn RHa);(2) selective estrogen receptor modulators or down-regulators(SERMs or SERDs); and(3) aromatase inhibitors(AIs), or a combination of two or more drugs. For patients aged less than 50 years and ER+ BC, there is no conclusive evidence that the combination of OFS and SERMs(i.e., tamoxifen) or chemotherapy is superior to OFS alone. Tamoxifen users exhibit a reduced risk of BC, both invasive and in situ, especially during the first 5 years of therapy, and extending the treatment to 10 years further reduced the risk of recurrences. SERDs(i.e., fulvestrant) are especially useful in the neoadjuvant treatment of advanced BC, alone or in combination with either cytotoxic agents or AIs. There are two types of AIs: type Ⅰ are permanent steroidal inhibitors of aromatase, while type Ⅱ are reversible nonsteroidal inhibitors. Several studies demonstrated the superiority of the third-generation AIs(i.e., anastrozole and letrozole) compared with tamoxifen, and adjuvant therapy with AIs reduces the recurrence risk especially in patients with advanced BC. Unfortunately, some cancers are or became ET-resistant, and thus other drugs have been suggested in combination with SERMs or AIs, including cyclin-dependent kinase 4/6 inhibitors(palbociclib) and mammalian target of rapamycin(m TOR) inhibitors, such as everolimus. Further studies are required to confirm their real usefulness.展开更多

内分泌治疗在激素受体阳性乳腺癌中扮演着至关重要的角色,并与患者的绝经状态密切相关。本文旨在深入探讨关于乳腺癌患者绝经状态判断的两个关键问题。第一,针对绝经前患者添加卵巢功能抑制(ovarian function suppression,OFS)治疗后,...内分泌治疗在激素受体阳性乳腺癌中扮演着至关重要的角色,并与患者的绝经状态密切相关。本文旨在深入探讨关于乳腺癌患者绝经状态判断的两个关键问题。第一,针对绝经前患者添加卵巢功能抑制(ovarian function suppression,OFS)治疗后,雌二醇(estradiol,E2)数值仍超标,可能存在“真性”超标和“假性”超标两种情况,氟维司群、阿贝西利、依西美坦及他莫昔芬等内分泌治疗药物可能干扰E2测定结果,需要警惕检测性“假性”超标的可能性。第二,在判断OFS治疗下患者是否已进入生理性绝经状态时,需考虑化疗对绝经状态的影响、围绝经期内分泌变化的复杂性等因素。建议根据患者年龄及内分泌治疗方案,考虑转换治疗并定期监测血清E2和卵泡刺激素(follicle-stimulating hormone,FSH)水平,针对疑难情况可综合抗缪勒管激素(anti-Mullerian hormone,AMH)、抑制素B(inhibin B,INHB)和雄激素等指标进行评估。展开更多
