  1. Quantitative estimates of the impact of sensitivity and specificity in mammographic screening in Germany.

    Article - En anglais

    Study objective

    To estimate quantitatively the impact of the quality of mammographic screening (in terms of sensitivity and specificity) on the effects and costs of nationwide breast cancer screening.

    Design

    Three plausible « quality » scenarios for a biennial breast cancer screening programme for women aged 50-69 in Germany were analysed in terms of costs and effects using the Microsimulation Screening Analysis model on breast cancer screening and the natural history of breast cancer.

    Firstly, sensitivity and specificity in the expected situation (or « baseline » scenario) were estimated from a model based analysis of empirical data from 35 000 screening examinations in two German pilot projects.

    In the second « high quality » scenario, these properties were based on the more favourable diagnostic results from breast cancer screening projects and the nationwide programme in The Netherlands.

    Thirdly, a worst case, « low quality » hypothetical scenario with a 25% lower sensitivity than that experienced in The Netherlands was analysed.

    Setting

    The epidemiological and social situation in Germany in relation to mass screening for breast cancer.

    Results

    In the « baseline » scenario, an 11% reduction in breast cancer mortality was expected in the total German female population, ie 2100 breast cancer deaths would be prevented per year. (...)
