JCEM:妊娠末期雌激素水平与母体乳腺癌关系如何?

2017-08-02 MedSci MedSci原创

大家知道足月妊娠可使母亲乳腺癌风险短暂增加但终生减少么?在妊娠末3个月雌酮(E1)、雌二醇(E2)、雌三醇(E3)是高浓度的雌激素。E1和E2的代谢产物产生致癌中介,而E3却不会。近日在JCEM上发表的一篇文章验证怀孕期间高浓度E3起保护作用而高浓度E1+E2增加风险的假设。

大家知道足月妊娠可使母亲乳腺癌风险短暂增加但终生减少么?在妊娠末3个月雌酮(E1)、雌二醇(E2)、雌三醇(E3)是高浓度的雌激素。E1和E2的代谢产物产生致癌中介,而E3却不会。近日在JCEM上发表的一篇文章验证怀孕期间高浓度E3起保护作用而高浓度E1+E2增加风险的假设。

研究人员对儿童健康与发展研究中心38年随访中共15528例孕妇进行了前瞻性队列研究(N=620;204乳腺癌病例),并测定了妊娠末3个月血清中E1、E2和E3水平,并估算了它们与乳腺癌风险的相关性。

总体而言,E1+E2加倍有很高的风险(风险比(HR)= 1.7,95%可信区间(CI)= 1.2-2.4)。相比之下,E3加倍则起到保护作用(HR = 0.7,95% CI = 0.5-1.0)。与分娩后16-38年、>27岁产妇、初产妇相比,分娩后2-15年(p=0.0002)、<<27岁产妇(p=0.01)、经产妇(p=0.02)与乳腺癌诊断关联性更强(p=0.0002)。

该研究显示妊娠末期3个月相对较高的E3水平可以保护妇女死于乳腺癌,而E1和E2可以提高风险。如果该研究结果在其他人群中得到证实,并在实验上得到支持,妊娠末期3个月雌激素可能有助于解释其对乳腺癌的影响。
