疾病控制中心(CDC)的研究者们发现,口服避孕药(OCs)的应用与宫颈原位癌(CIS)的危险性之间有阳性关系,但他们相信那些结果代表检测偏差(detection bias),而不属于OCs的真正致癌作用。研究者说“虽然我们不能排除OCs对宫颈有短暂致癌作用的可能性,但相信我们的研究,在数量上表明检测偏差是阳性关系的可能原因。” CDC生殖卫生科Irwin最近在Atlanta举行的第35届流行病情报处年会上介绍了在Costa Rican研究的发现。
Researchers at the Centers for Disease Control and Prevention (CDC) have found a positive relationship between the use of oral contraceptives (OCs) and the risk of cervical carcinoma in situ (CIS), but believe the results represent detection bias, It does not belong to the true carcinogenic effects of OCs. “While we can not rule out the possibility of OCs having a transient carcinogenic effect on the cervix, the researchers say,” we believe our study shows quantitatively that the test bias is a possible cause of the positive relationship. "Irwin, CDC’s Reproductive Health Division, The 35th Annual Epidemiology Information Office presented the findings of the Costa Rican study.
