Purpose: To spare DCIS patients from overtreatment, treatment de-escalated over the years. This study evaluates the influence of these developments on the patterns of care in the treatment of DCIS with particular interest in the use of breast conserving surgery (BCS), radiotherapy following BCS and the use and type of axillary staging.
Methods: In this large population-based cohort study all women, aged 50-74 years diagnosed with DCIS from January 1989 until January 2019, were analyzed per two-year cohort.
Background Trends in the detection of suspicious microcalcifications at mammography screening and the yield of these lesions after recall are unknown. Purpose To determine trends in recall and outcome of screen-detected microcalcifications during 20 years of mammography screening. Materials and Methods The authors performed a retrospective analysis of a consecutive series of 817 656 screening examinations (January 1997 to January 2017) in a national breast screening program.

Methods: All women with an excision biopsy among 817,656 screens, obtained from January 1997 to January 2017, were included.
Results: Of 18,593 recalled women (recall rate, 2.
Purpose: In a biennial screening mammography programme, we analysed the trends in incidence of screen-detected DCIS and invasive breast cancers in the era of screen-film mammography (SFM) screening, the period of the transition to full-field digital mammography (FFDM) screening and the period of FFDM screening. We also investigated a possible association between the incidence and grading of screen-detected DCIS and invasive breast cancer.
Methods: In the southern part of the Netherlands, FFDM screening gradually replaced SFM screening between May 2009 and April 2010.
