曲妥珠单抗是一种针对HER2酪氨酸激酶受体的单抗。大多数最初对曲妥珠单抗有反应的转移性乳腺癌患者在治疗开始后一年内出现耐药性,在辅助治疗环境中,尽管使用曲妥珠单抗治疗,仍有15%的患者复发。在这篇综述中,我们讨论了曲妥珠单抗抗肿瘤活性的潜在机制,以及这些机制如何改变以促进治疗耐药。我们还讨论了可能提高曲妥珠单抗疗效的新疗法,这为患有HER2过表达肿瘤的乳腺癌患者提供了极大地提高生存率的希望。
Trastuzumab is a monoclonal antibody targeted against the HER2 tyrosine kinase receptor. The majority of patients with metastatic breast cancer who initially respond to trastuzumab develop resistance within one year of treatment initiation, and in the adjuvant setting 15% of patients still relapse despite trastuzumab-based therapy. In this review, we discuss potential mechanisms of antitumor activity by trastuzumab, and how these mechanisms become altered to promote therapeutic resistance. We also discuss novel therapies that may improve the efficacy of trastuzumab, and that offer hope that the survival of breast cancer patients with HER2-overexpressing tumors can be vastly improved.
