Incidence and detection rates were calculated. Descriptive analysis of the cases was performed and, for comparative analysis, grade of DCIS was analysed as a binary variable (high vs. low\/intermediate) in keeping with the inclusion criteria for active surveillance trials. Analysis was performed in IBM Statistical Package for Social Sciences, version 26.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Between 2008 and 2020, 2240 women were diagnosed with DCIS through BreastCheck; 876 (39.1%) were low\/intermediate-grade. The overall incidence rate has remained relatively stable during this period. Women with low\/intermediate-grade DCIS were younger than women with high-grade DCIS (56 (interquartile range: 56-61) years v 57 (interquartile range: 53\u201361) years; p\u2009&lt;\u20090.001). They were also more likely to have been diagnosed at an initial screening episode compared with those who had high-grade lesions (42.5% v 29.0%; p\u2009&lt;\u20090.001).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>If current clinical trials recommend active surveillance as a feasible option for DCIS, up to 40% of women with screen-detected DCIS may be eligible. These women are younger and often diagnosed on initial screening episode, so may require longer active follow-up.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1177\/09691413221090739","type":"journal-article","created":{"date-parts":[[2022,3,28]],"date-time":"2022-03-28T03:08:28Z","timestamp":1648436908000},"page":"172-177","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":1,"title":["Screen-detected ductal carcinoma in situ, 2008\u20132020: An observational study"],"prefix":"10.1177","volume":"29","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7382-2377","authenticated-orcid":false,"given":"Caitriona","family":"Kelly","sequence":"first","affiliation":[{"name":"School of Public Health, Physiotherapy and Sports Science, University College Dublin, Dublin, Ireland"},{"name":"Department of Public Health HSE North East, Navan, Ireland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2524-3677","authenticated-orcid":false,"given":"Patricia","family":"Fitzpatrick","sequence":"additional","affiliation":[{"name":"School of Public Health, Physiotherapy and Sports Science, University College Dublin, Dublin, Ireland"},{"name":"National Screening Service, Dublin, Ireland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Cecily","family":"Quinn","sequence":"additional","affiliation":[{"name":"BreastCheck, National Screening Service, Dublin, Ireland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Fidelma","family":"Flanagan","sequence":"additional","affiliation":[{"name":"BreastCheck, National Screening Service, Dublin, Ireland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Alissa","family":"Connors","sequence":"additional","affiliation":[{"name":"BreastCheck, National Screening Service, Dublin, Ireland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Aideen","family":"Larke","sequence":"additional","affiliation":[{"name":"BreastCheck, National Screening Service, Dublin, Ireland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Therese","family":"Mooney","sequence":"additional","affiliation":[{"name":"National Screening Service, Dublin, Ireland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Maria","family":"Kennedy","sequence":"additional","affiliation":[{"name":"BreastCheck, National Screening Service, Dublin, Ireland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Margaret","family":"Sheehan","sequence":"additional","affiliation":[{"name":"BreastCheck, National Screening Service, Dublin, Ireland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Michael W.","family":"Bennett","sequence":"additional","affiliation":[{"name":"National Screening Service, Dublin, Ireland"},{"name":"Department of Pathology, Cork University Hospital, Cork, Ireland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Caroline","family":"Brodie","sequence":"additional","affiliation":[{"name":"BreastCheck, National Screening Service, Dublin, Ireland"},{"name":"Department of Anatomic Pathology, Galway University Hospital and National University of Ireland, Galway, Ireland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ann","family":"O\u2019Doherty","sequence":"additional","affiliation":[{"name":"BreastCheck, National Screening Service, Dublin, Ireland"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2022,3,28]]},"reference":[{"key":"bibr1-09691413221090739","doi-asserted-by":"publisher","DOI":"10.4161\/cbt.10.10.13879"},{"key":"bibr2-09691413221090739","doi-asserted-by":"publisher","DOI":"10.1016\/j.ajpath.2018.07.031"},{"key":"bibr3-09691413221090739","doi-asserted-by":"publisher","DOI":"10.1007\/s11912-019-0777-3"},{"key":"bibr4-09691413221090739","doi-asserted-by":"publisher","DOI":"10.1016\/j.ajpath.2018.08.020"},{"key":"bibr5-09691413221090739","doi-asserted-by":"publisher","DOI":"10.1097\/gme.0000000000001397"},{"key":"bibr6-09691413221090739","doi-asserted-by":"publisher","DOI":"10.1016\/j.pathol.2019.07.005"},{"key":"bibr7-09691413221090739","doi-asserted-by":"publisher","DOI":"10.1016\/j.jamcollsurg.2019.01.018"},{"key":"bibr8-09691413221090739","unstructured":"Women\u2019s Health Programme Irish College General Practitioners ICGP.
