Breast cancer, a leading cause of increased morbidity and mortality among women, overexpresses the human epidermal growth factor receptor 2 in approximately 20% to 30% of cases. Trastuzumab (Trz), a monoclonal antibody against the human epidermal growth factor receptor 2, improves survival in breast cancer patients in both the adjuvant and metastatic settings. Despite the therapeutic benefits of Trz, there is an increased incidence of cardiotoxicity, particularly when administered following anthracycline-based chemotherapy. The pathogenesis underlying Trz-mediated cardiotoxicity remains poorly understood. The present review focuses on the current understanding of Trz-mediated cardiotoxicity from both the basic and clinical science perspectives.
乳腺癌是女性发病率和死亡率上升的主要原因之一,在约20%至30%的病例中过度表达人表皮生长因子受体2。曲妥珠单抗(Trz)是一种针对人表皮生长因子受体2的单克隆抗体,在辅助治疗和转移性治疗中均可提高乳腺癌患者的生存率。尽管Trz具有治疗益处,但心脏毒性的发生率有所增加,尤其是在基于蒽环类化疗后使用时。Trz介导的心脏毒性的发病机制仍知之甚少。本综述从基础科学和临床科学的角度聚焦于对Trz介导的心脏毒性的当前认识。
