Breast cancer is the second-leading cause of metastatic disease in the central nervous system (CNS). Recent advances in the biological understanding of breast cancer have facilitated an unprecedented increase of survival in a subset of patients presenting with metastatic breast cancer. Patients with HER2 positive (HER2+) or triple negative breast cancer are at highest risk of developing CNS metastasis, and typically experience a poor prognosis despite treatment with local and systemic therapies. Among the obstacles ahead in the realm of developmental therapeutics for breast cancer CNS metastasis is the improvement of our knowledge on its biological nuances and on the interaction of the blood–brain barrier with new compounds. This article reviews recent discoveries related to the underlying biology of breast cancer brain metastases, clinical progress to date and suggests rational approaches for investigational therapies.
乳腺癌是中枢神经系统(CNS)转移性疾病的第二大主要原因。近年来,对乳腺癌生物学的深入了解,使得一部分转移性乳腺癌患者的生存率得到了前所未有的提高。HER2 阳性(HER2+)或三阴性乳腺癌患者发生 CNS 转移的风险最高,尽管采用局部和全身治疗,但其预后通常较差。在乳腺癌 CNS 转移的发展治疗领域中,面临的挑战之一是提高我们对其生物学细微差别以及血脑屏障与新化合物相互作用的认识。本文综述了与乳腺癌脑转移的基础生物学相关的最新发现、迄今为止的临床进展,并为探索性治疗提出了合理的方法。
