JAMA:遗传性HMG-CoA还原酶抑制降低卵巢癌风险

遗传性HMG-CoA还原酶抑制人群的上皮性卵巢癌风险较低

临床前和流行病学研究表明,他汀类药物在上皮性卵巢癌中具有潜在的化学预防作用。近日研究人员考察了HMG-CoA还原酶与卵巢上皮性癌人群和BRCA1/2突变携带者遗传抑制的相关性。

OCAC队列包含63347例侵袭性上皮性卵巢癌病例及对照,CIMBA队列包含31448BRCA1/2突变卵巢癌病例及对照,全基因组关联研究(GWAS)荟萃分析中,研究人员分析了HMGCR、NPC1L1、PCSK9等与低密度脂蛋白(LDL)胆固醇相关的单核苷酸多态性。

OCAC队列包括22406名浸润性上皮性卵巢癌患者和40941名对照个体,CIMBA样本包括3887名上皮性卵巢癌患者和27561名对照个体。2队列参与者年龄在41.5到59.0岁之间。在初步分析中,遗传性HMG-CoA还原酶抑制,导致LDL胆固醇降低1-mmol/L(37.7 mg/dL),与卵巢上皮癌的风险降低相关(OR:0.60)。在BRCA1/2突变携带者中, 遗传性HMG-CoA还原酶抑制与卵巢癌风险降低(危险比0.69)有关。二次分析显示, NPC1L1(OR:0.97)或PCSK9(OR:0.98)多态性,以及循环LDL胆固醇(OR:0.98)与卵巢癌风险无显著相关。

研究发现,遗传性HMG-CoA还原酶抑制人群的上皮性卵巢癌风险较低。
