Our study tested the hypothesis that reluctance to perform prostate biopsies in men who are anticoagulated results in lower rates of diagnosed prostate cancer, leading to an apparent protective effect. Rates of prostate biopsies have decreased from 2000 to 2015, allowing calendar time to be used as the intervention. In a national population\u2010based sample of elderly men, our study compared trends in prostate cancer incidence between 17,815 men treated with chronic oral anticoagulation for prosthetic heart valve thromboprophylaxis and a general population comparison group of 356,300 men. Cancer events were based on administrative claims. Among men enrolled in 2000\u20132001 and followed through 2015, prostate cancer incidence was substantially lower in the anticoagulation group (adjusted incidence rate ratio [IRR] 0.70; 95% confidence interval [CI] 0.62\u20130.80). Incidence decreased over time in the general population group to approach that of the anticoagulation group among men enrolled in 2008\u20132010 (IRR 0.86; 95% CI 0.71\u20131.04). Rates of prostate biopsies also decreased over time in the general population group to match the rate in the anticoagulation group. These results indicate that the apparent protective effect of warfarin treatment on the risk of prostate cancer is likely the result of detection bias from lower rates of biopsies among men who are anticoagulated.<\/jats:p>","DOI":"10.1002\/ijc.32712","type":"journal-article","created":{"date-parts":[[2019,10,4]],"date-time":"2019-10-04T03:01:27Z","timestamp":1570158087000},"page":"3022-3025","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Chronic oral anticoagluation and risk of prostate cancer: Evidence of detection bias"],"prefix":"10.1002","volume":"146","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1857-9367","authenticated-orcid":false,"given":"Michael M.","family":"Ward","sequence":"first","affiliation":[{"name":"National Institute of Arthritis and Musculoskeletal and Skin Diseases, National Institutes of Health  Bethesda MD"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2019,10,23]]},"reference":[{"key":"e_1_2_6_2_1","doi-asserted-by":"publisher","DOI":"10.1056\/NEJM200006293422604"},{"key":"e_1_2_6_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/S1470-2045(07)70046-3"},{"key":"e_1_2_6_4_1","doi-asserted-by":"publisher","DOI":"10.1182\/blood-2010-08-304758"},{"key":"e_1_2_6_5_1","doi-asserted-by":"publisher","DOI":"10.1093\/aje\/kwr268"},{"key":"e_1_2_6_6_1","doi-asserted-by":"publisher","DOI":"10.1007\/s10552-014-0417-z"},{"key":"e_1_2_6_7_1","doi-asserted-by":"publisher","DOI":"10.1002\/ijc.27905"},{"key":"e_1_2_6_8_1","doi-asserted-by":"publisher","DOI":"10.1080\/21681805.2016.1228085"},{"key":"e_1_2_6_9_1","doi-asserted-by":"publisher","DOI":"10.1001\/jamainternmed.2017.5512"},{"key":"e_1_2_6_10_1","doi-asserted-by":"publisher","DOI":"10.1002\/ijc.31886"},{"key":"e_1_2_6_11_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.eururo.2013.05.049"},{"key":"e_1_2_6_12_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.crad.2012.08.005"},{"key":"e_1_2_6_13_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.eururo.2016.03.015"},{"key":"e_1_2_6_14_1","doi-asserted-by":"publisher","DOI":"10.1097\/01.mlr.0000160417.39497.a9"},{"key":"e_1_2_6_15_1","doi-asserted-by":"publisher","DOI":"10.1161\/01.STR.0000230607.07928.17"},{"key":"e_1_2_6_16_1","doi-asserted-by":"publisher","DOI":"10.1007\/s12325-018-0782-1"},{"key":"e_1_2_6_17_1","doi-asserted-by":"publisher","DOI":"10.1053\/j.ajkd.2007.11.023"},{"key":"e_1_2_6_18_1","unstructured":"2001\u20132015 Database: National Program of Cancer Registries and Surveillance Epidemiology and End Results SEER*Stat Database: NPCR and SEER Incidence\u2014USCS 2001\u20132015 Public Use Research Database United States Department of Health and Human Services Centers for Disease Control and Prevention and National Cancer Institute.
