In a retrospective case-control-study 500 women with a carcinoma in situ of the cervix uteri and 500 controls were examined by a standardized interview and compared by matched pair analysis. 8 risk factors for ca in situ were found indicating a lower social status, earlier sexual activities and more frequent inflammations of the cervix uteri. However screening programs should not be restricted to such women because it is difficult and expensive to identify and to reach the high risk group.
在一项回顾性病例对照研究中，对500名子宫颈原位癌女性患者和500名对照者进行了标准化访谈检查，并通过配对分析进行比较。发现了8个原位癌的危险因素，表明社会地位较低、性活动较早以及子宫颈炎症更频繁。然而，筛查项目不应仅限于此类女性，因为识别和接触高危人群既困难又昂贵。
