Age specific sensitivity and sojourn time in a breast cancer screening programme (DOM) in The Netherlands: a comparison of different methods.

STUDY OBJECTIVE: To estimate age dependent sensitivity and sojourn time in a breast cancer screening programme by different methods. POPULATION AND METHODS: The study population comprised women participating in the DOM project--the Utrecht screening programme for the early detection of breast cancer. Breast cancer screening prevalence data and incidence rates after a negative screen were used to estimate age specific sensitivity and mean sojourn time by different methods. MAIN RESULTS: Maximum likelihood estimates of the mean sojourn time varied from one year for women aged 40-49 years to thre... Mehr ...
