携带BRCA1致病性突变的女性或卵巢储备功能下降,生育时间有缩短的可能性!

BRCA1和BRCA2基因通过同源重组在双链DNA断裂(DSB)修复中具有至关重要的作用。现已明确,BRCA1/2基因突变与乳腺癌卵巢癌风险增加有关。但是,BRCA1/2基因突变与卵巢储备功能的相关性尚不清楚。

本研究旨在明确胚系BRCA(gBRCA)致病变异是否与卵巢储备功能下降有关。

研究人员使用了五个数据集对828名进行了gBRCA检测的女性进行了单独的患者水平数据荟萃分析。在这828名女性中,250名携带gBRCA突变,另578名未检测到gBRCA突变(对照)。在携带gBRCA突变的女性中,4个中心研究的受试者是乳腺癌患者(n=161),1个研究的受试者是健康个体(n=89)。根据研究中心、年龄、体重指数、吸烟和口服避孕药的使用进行校正数据。在系统治疗之前测定了受试女性的抗苗勒管激素(AMH)水平。

有无BRCA突变的AMH值

有无gBRCA1/2突变(34.1 ± 4.9 v 34.3 ± 4.8 岁,p=0.48),以及携带gBRCA1或gBRCA2突变(33.7 ± 4.9 v 34.6 ± 4.8 岁,p=0.16)的女性的平均年龄均相近。经校正后,携带gBRCA1/2突变的女性的AMH水平明显低于对照组(低 23%;95% CI 4-38,p=0.02)。对患病女性(157位携带gBRCA突变 vs 524位不携带突变)进行校正分析时,上述差异仍存在(低 25%;95% CI 9-38,p=0.003)。

携带gBRCA1突变 vs gBRCA2突变的AMH水平

与对照相比,携带gBRCA1突变的女性的AMH水平明显更低(低 33%,95% CI 12-49,p=0.004),但携带gBRCA2突变的女性的AMH水平没有明显低于对照组(低 7%,95% CI 低 31% - 高 26%,p=0.64)。

综上所述,携带gBRCA致病变异的年轻女性,特别是那些患有乳腺癌和携带gBRCA1突变的,血清AMH水平明显低于对照个体,提示卵巢储备功能下降。鉴于这类个体的卵巢储备功能下降,可能需要优先提示她们生育时间有缩短的可能性。
