Positive diagnostic values and histological detection ratios from the Rotterdam cervical cancer screening programme

BACKGROUND: In organized screening programmes for cervical cancer, pre-cancerous lesions are detected by cervical smears. However, during follow-up after a positive smear these pre-cancerous lesions are not always found. The purpose of the study is to analyse positive diagnostic values of smears of at least mild dysplasia, made under the organized screening programmes in the Rotterdam area (1979-1991), and detection ratios of histologically confirmed CIN > or =3, among women participating in these screening programmes. METHODS: Positive diagnostic values and histological detection ratios, b... Mehr ...
