Aromatase is an enzyme that converts testosterones to estrogens. Inhibition of this enzyme has been shown to have several clinical utilities in breast cancer. Currently, there are three aromatase inhibitors (AIs) in clinical use, namely anastrozole, letrozole, and exemestane. AIs have been used in various clinical settings for breast cancer, ranging from chemoprevention in breast cancer to treating breast cancer in both early stage in the adjuvant setting and metastatic disease. This article reviews mechanism of action, AI classification, and clinical utilities of AIs in various clinical settings in the context of breast cancer.
芳香化酶是一种将睾酮转化为雌激素的酶。已证明抑制该酶在乳腺癌中有多种临床应用。目前,有三种芳香化酶抑制剂(AIs)正在临床使用,即阿那曲唑、来曲唑和依西美坦。AIs已被用于乳腺癌的各种临床场景,从乳腺癌的化学预防到辅助治疗早期乳腺癌以及转移性疾病。本文在乳腺癌的背景下综述了AIs在各种临床场景中的作用机制、AI分类及临床应用。
