This review describes the current treatment of human epidermal growth factor receptor-2 (HER2)-positive breast cancer with a focus on recently reported clinical trials.Treatment of resistant disease and central nervous system metastases will be reviewed as will new agents that are being developed to target HER2-amplified breast cancers.
Recent studies evaluating trastuzumab-resistant breast cancer have shown a benefit of continuing trastuzumab with chemotherapy or with another HER2-targeted agent.Targeting the vascular endothelial growth factor, mammalian target of rapamycin, and PI3 kinase pathways in addition to HER2 may enhance efficacy compared with individual agents. Several novel anti-HER2 compounds are being evaluated with promising early data.
HER2-positive breast cancer has traditionally been associated with poor prognosis.However, treatment with HER2-targeted therapies has changed the natural history of this disease. Greater success depends on elucidating mechanisms of resistance and exploring new methods of blocking signal transduction via HER2 and related pathways.
本文主要介绍了人表皮生长因子受体 2(HER2)阳性乳腺癌的治疗方法,重点关注了最近报道的临床试验。我们还将回顾耐药性疾病和中枢神经系统转移的治疗方法,以及正在开发用于治疗 HER2 扩增型乳腺癌的新药物。
最近评估曲妥珠单抗耐药性乳腺癌的研究表明,继续使用曲妥珠单抗联合化疗或另一种 HER2 靶向药物治疗具有获益。与单一药物相比,针对血管内皮生长因子、雷帕霉素哺乳动物靶蛋白和 PI3 激酶通路联合 HER2 可能会提高疗效。目前正在评估几种新型抗 HER2 化合物,早期数据显示出良好的效果。
HER2 阳性乳腺癌传统上与预后不良相关。然而,HER2 靶向治疗改变了这种疾病的自然病程。更大的成功取决于阐明耐药机制,并探索通过 HER2 及相关通路阻断信号转导的新方法。
