细胞周期蛋白依赖性激酶4和6(CDK4/6)抑制剂已成为激素受体阳性(HR+)/人表皮生长因子受体2阴性(HER2-)晚期乳腺癌的标准治疗。然而,对于CDK4/6抑制剂耐药的患者,尤其是原发耐药或快速进展患者的后续治疗,目前仍缺乏标准推荐。CDK4/6抑制剂的再挑战,磷脂酰肌醇3-激酶(PI3K)/蛋白激酶B(AKT)/雷帕霉素靶蛋白(mTOR)抑制剂的联合使用、新型抗体药物偶联物(ADC)以及新型内分泌治疗药物等,均是CDK4/6抑制剂进展后患者可选的治疗策略。此外,众多新型靶向药物和新的联合治疗策略也在不断探索。未来还应建立基于生物标志物指导下的精准治疗策略,以及不同治疗的最佳使用顺序。
CDK4/6 inhibitors have become the standard of care for HR-positive, HER2-negative advanced breast cancer. However, there is still a lack of standard recommendations for the subsequent treatment of patients with CDK4/6 inhibitor resistance, especially those with primary resistance or rapid progression. Currently, appropriate treatment strategies included re-challenge of CDK4/6 inhibitors, combination with PI3K/AKT/mTOR inhibitors, new antibody drug conjugate (ADC), novel endocrine therapy drugs, and chemotherapy. In addition, many new targeted drugs and new combination treatment strategies are also being explored. In the future, precise treatment strategies based on biomarkers should be established, as well as the optimal sequence of use of different therapies.
