NEJM:戈舍瑞林可有效保护化疗期间乳癌患者的卵巢功能

2015-03-05 Mechront MedSci原创

随着检测技术的提高,乳腺癌患者不仅越来越多,还越来越年轻化。辅助化疗是乳腺癌治疗的常用手段,但其对卵巢有不可估量的毒副作用,常导致卵巢功能衰竭。在激素受体阴性的乳腺癌女性患者中,化疗过程中使用措施对卵巢进行保护是迫切需要的。目前学术界有关于GnRH激动剂保护卵巢功能的研究报道,但所得结果有好有坏,仍存争议,并且缺乏关于此类女性妊娠结局的数据。因此Halle C.F.等人在2004-02至

随着检测技术的提高,乳腺癌患者不仅越来越多,还越来越年轻化。辅助化疗是乳腺癌治疗的常用手段,但其对卵巢有不可估量的毒副作用,常导致卵巢功能衰竭。在激素受体阴性的乳腺癌女性患者中,化疗过程中使用措施对卵巢进行保护是迫切需要的。目前学术界有关于GnRH激动剂保护卵巢功能的研究报道,但所得结果有好有坏,仍存争议,并且缺乏关于此类女性妊娠结局的数据。因此Halle C.F.等人在2004-02至2011-05期间进行了一项研究以探究GnRH激动剂戈舍瑞林在化疗过程中对女性卵巢功能的保护作用。最新研究成果发表在近期NEJM上。

最终参与该研究的为218名未绝经女性,均为可手术、激素受体阴性的乳腺癌患者。研究者将其随机分为两组,试验组为化疗加GnRH激动剂戈舍瑞林(N=105),对照组只使用化疗(N=113)。以第2年卵巢功能衰竭作为原始结局指标,卵巢功能衰竭定义为:在这之前6个月都没有来月经,FSH水平处于绝经后范围。以妊娠结局、无病生存率和总生存率作为次级结局指标。

该研究结果显示,218名参与者中,有135名得到了原始结局指标,试验组卵巢功能衰竭数据为8%,对照组有22%,两组比较,OR=0.20,95% CI 0.09-0.97,P=0.04。因缺乏数据较多,对其进行敏感性分析之后,得出该结果是稳健的。缺乏数据在不同治疗组,或根据年龄、化疗等分层因素分层后没有差异。该研究还得出,在218名参与女性中,试验组和对照组妊娠数据为:21% vs. 11%,P=0.03。试验组无病生存率得到改善,P=0.004;试验组总生存率得到改善,P=0.05。

该研究结果表明,GnRH激动剂戈舍瑞林可以有效保护化疗期间乳腺癌患者的卵巢功能,避免卵巢功能衰竭,减少提前进入更年期的风险,改善其生育率。
