CEBP:尿液中氧化应激标志物8-oxodG与ER阳性乳腺癌发生相关

2013-07-26 MedSci MedSci原创

氧化应激可能是肿瘤发生有关,因此一项假设研究尿液中氧化应激相关的分子标志物8-oxodG与乳腺癌发生的关系。这是一项巢氏队列研究,收集了24697例50-64岁绝经后妇女,并进行了3-7年的随访。在未发生乳腺癌的人群中,对发生乳腺癌的病例进行匹配。共匹配336例,比较ER阳性和ER阴性乳腺癌发生情况。研究结果显示,尿液中8-oxodG与乳腺癌发生阳性相关。与ER阳性的乳腺癌相关性更大

8-oxodG与乳腺癌发生的关系。这是一项巢氏队列研究,收集了24697例50-64岁绝经后妇女,并进行了3-7年的随访。在未发生乳腺癌的人群中,对发生乳腺癌的病例进行匹配。共匹配336例,比较ER阳性和ER阴性乳腺癌发生情况。

研究结果显示,尿液中8-oxodG与乳腺癌发生阳性相关。与ER阳性的乳腺癌相关性更大 (IRR: 1.11; 1.01–1.23) ,以及与饮食中铁摄及有关(IRR: 1.10; 1.06–1.37 per unit increase),与是否使用雌激素替代治疗关系不大(IRR: 1.11; 0.97–1.26)。因此,认为尿液中8-oxodG可能与ER阳性乳腺癌的风险增加相关。
