Few studies have addressed these challenges across site\u2010specific cancer diagnoses. The present study aimed to examine the sensitivity and negative predictive value (NPV) of self\u2010reported cancer in a Danish nationwide survey among adults aged \u226516\u2009years, using registry data as the criterion standard. Moreover, the influence of sociodemographic variables and time since diagnosis on sensitivity was explored using multiple logistic regression models. Self\u2010reported data on cancer history of any site were derived from the Danish National Health Survey 2017 (n\u2009=\u2009183\u2009372). Individual\u2010level survey data were linked to data from the Danish Cancer Registry on 10 site\u2010specific cancer diagnoses. NPV was consistently high \u226599.5% across the included cancer diagnoses. In contrast, sensitivity varied greatly and was lowest for cancer in brain\/central nervous system (CNS) among both men (25.6%) and women (23.9%) and highest for rectal cancer among men (96.9%) and for breast cancer among women (98.9%). Sensitivity was also relatively low for nonmelanoma skin cancer (41.4% among men; 44.6% among women) and urinary tract cancer (60.0% among men; 60.4% among women). When restricting diagnostic definitions for cancer in brain\/CNS and urinary tract cancer to include only malignant neoplasms, sensitivity increased. For several cancer diagnoses, sensitivity decreased with increasing age and lower educational level, whereas conflicting results were observed for time from diagnosis to self\u2010report. Future studies are encouraged to use self\u2010reported cancer history data with caution and for example, include questions on only site\u2010specific cancer diagnoses with high sensitivity.<\/jats:p>","DOI":"10.1002\/ijc.34692","type":"journal-article","created":{"date-parts":[[2023,8,19]],"date-time":"2023-08-19T15:23:49Z","timestamp":1692458629000},"page":"217-225","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Variations in the agreement of self\u2010reported cancer: A Danish nationwide study"],"prefix":"10.1002","volume":"154","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7171-7429","authenticated-orcid":false,"given":"Heidi Amalie Rosendahl","family":"Jensen","sequence":"first","affiliation":[{"name":"National Institute of Public Health University of Southern Denmark  Copenhagen K Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Trine Allerslev","family":"Horsb\u00f8l","sequence":"additional","affiliation":[{"name":"National Institute of Public Health University of Southern Denmark  Copenhagen K Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lau Caspar","family":"Thygesen","sequence":"additional","affiliation":[{"name":"National Institute of Public Health University of Southern Denmark  Copenhagen K Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michael","family":"Davidsen","sequence":"additional","affiliation":[{"name":"National Institute of Public Health University of Southern Denmark  Copenhagen K Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anne Illemann","family":"Christensen","sequence":"additional","affiliation":[{"name":"National Institute of Public Health University of Southern Denmark  Copenhagen K Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ola","family":"Ekholm","sequence":"additional","affiliation":[{"name":"National Institute of Public Health University of Southern Denmark  Copenhagen K Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2023,8,18]]},"reference":[{"key":"e_1_2_11_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0140-6736(19)32007-0"},{"key":"e_1_2_11_3_1","unstructured":"The Cause of Death Register 2020.Danish Health Data Authority 2022.
