摘要:

三阳性乳腺癌是指雌激素受体(estrogen receptor,ER)、孕激素受体(PR)和人类表皮生长因子受体2(human epidermal growth factor receptor 2,HER2)均为阳性,约占HER2阳性乳腺癌病人总数的50%~60%。三阳性乳腺癌中存在的ER信号通路和HER2信号通路之间的交互作用可能会削弱其抗HER2治疗和内分泌治疗的疗效,这一特点引起了广泛的关注。越来越多的证据显示,同时阻断HER2信号通路和ER信号通路,如采用抗HER2双靶向+内分泌治疗±CDK4/6抑制剂,可有效规避治疗之间的相互耐药,提高治疗效果且安全性良好。同时,生物标志物也在积极探索中,包括Ki67、内生亚型及多基因检测等,有助于选择真正获益的人群,指导精准治疗。

Abstract:

Triple positive breast cancer overexpress ER (estrogen receptor), PR and HER2 (human epidermal growth factor receptor 2, HER2), accounting for about 50%-60% of the HER2 positive breast cancer patients. Based on the data from clinical trials, the crosstalk between the ER signaling pathway and the HER2 signaling pathway in triple-positive breast cancer may weaken the efficacy of anti-HER2 therapy and endocrine therapy, and this feature has attracted widespread attention. Emerging evidence shows that while blocking HER2 signaling pathway, together with enhancing blocking of ER signaling pathway, such as anti-HER2 dual-targeting + endocrine therapy ± CDK4/6 inhibitors, could effectively overcome drug resistance, and improve the efficacy. Predictive biomarkers including Ki67, intrinsic subtypes, and multi-gene assay, which have the potential benefit for personalized treatment.

Key words: triple positive breast cancer, crosstalk, treatment strategy, biomarkers
