Lancet oncol:芳香化酶抑制剂治疗乳腺癌的更佳时间,以及三种芳香化酶抑制剂的疗效对比

2018-02-24 MedSci MedSci原创

目前,利用芳香化酶抑制剂辅助治疗乳腺癌的最佳时间尚不确定,现也无临床试验直接对比三种芳香化酶抑制剂阿那曲唑(anastrozole)、依西美坦(exemestane)和来曲唑( letrozole)的效果。近日,Lancet子刊上发表一篇文章,研究人员对芳香化酶抑制剂用作辅助治疗雌激素受体阳性的早期乳腺癌的时间和类型进行评估。研究人员进行多中心的、开放性、随机化临床三期试验(FATA-GIM3),

目前,利用芳香化酶抑制剂辅助治疗乳腺癌的最佳时间尚不确定,现也无临床试验直接对比三种芳香化酶抑制剂阿那曲唑(anastrozole)、依西美坦(exemestane)和来曲唑( letrozole)的效果。近日,Lancet子刊上发表一篇文章,研究人员对芳香化酶抑制剂用作辅助治疗雌激素受体阳性的早期乳腺癌的时间和类型进行评估。

研究人员进行多中心的、开放性、随机化临床三期试验(FATA-GIM3),招募病理确诊的浸润性雌激素受体阳性的完全手术切除(肿瘤和腋窝淋巴结)的早期乳腺癌患者,予以6种不同的治疗。并排除采用激素替代疗法、复发或转移的、既往采取它莫西芬治疗以及既往10年患过其他恶性肿瘤的患者。符合要求的患者被随机均分至6个治疗组:口服阿那曲唑(1mg/日)、依西美坦(25mg/日)或来曲唑(2.5mg/日)(均持续5年)(upfront策略);或先口服它莫西芬(20mg/日)2年,随后口服上述三种芳香化酶抑制剂的一种,持续3年(switch策略)。主要评估指标:无进展存活期。

2007年3月9日-2012年7月31日,共招募3697位患者。中位随访60个月(IQR 46-72),共报道401例无进展存活病例,其中switch治疗组1850位患者中有211位(11%)、upfrongt治疗组1847位患者中有190位(10%)。switch治疗组和upfrongt治疗组的5年无进展存活率分别是88.5%(95% CI 86.7–90.0)和89.8%(88.2–91.2;危险比[HR]0.89,95% CI 0.73–1.08; p=0.23) 。阿那曲唑(124位)、依西美坦(148位)和来曲唑(129位)三组的5年无进展存活率分别是90.0%(95% CI 87.9–91.7)、88.0%(85.8–89.9)和89.4%(87.3 -91.1) (p=0.24)。未观察到预期外的重度不良反应和治疗相关的死亡。最常见的3-4级副反应是肌肉骨骼性副反应,switch治疗组的1761位患者中报道了130例(7%),upfront治疗组1766位患者中报道了128例(7%)。upfront治疗组的1级肌肉骨骼性副反应明显多于switch治疗组(924例[52%] vs 745例[42%])。两组的其他所有3-4级副反应发生率均低于2%。

芳香化酶抑制剂治疗5年的效果并不优于它莫西芬治疗2年+它莫西芬治疗3年的效果。三种芳香化酶抑制剂没有一种的疗效明显优于另外两种。因此,应根据患者的偏好、耐受性和经济状况等确定最佳的个性化的治疗方案。
