Resistance to endocrine therapy is the major problem for ERα(+) breast cancer patients. Research in endocrine resistance, mainly based on breast cancer cell lines and transplantation animal models, has indicated that phosphorylation of estrogen receptors, high expression of SRC and high activation of ErbB/MAPK pathway are the 3 main mechanisms for occurrence of endocrine resistance. Restoration of ER expression and exploration of inhibitors to various biological targets are the 2 promising ways to solve this problem. Further research is needed to deeply explore relevant mechanisms and resolvents so as to guide clinical practice.
内分泌治疗耐药是 ERα(+)乳腺癌患者面临的主要问题。内分泌耐药相关研究主要基于乳腺癌细胞系和移植动物模型,提示雌激素受体磷酸化、 SRC 高表达和 ErbB/MAPK 通路持续激活是内分泌耐药发生的 3 个主要机制。恢复 ER 表达和探索针对各种生物学靶点的抑制剂是解决这一问题的 2 种有前途的方法。需要进一步深入研究相关机制和解决方法,以指导临床实践。
