Therefore, we conducted a population\u2010based study including 47,220 patients with hematological malignancies (diagnosed 1992\u20132006) and their 235,868 matched controls to define the incidence and risk factors for suicide and suicide attempt. Information on suicides, suicide attempts, and preexisting psychiatric disorders was obtained from Swedish registers and individual medical records. There was a twofold increased (hazard ratio [HR]\u00a0=\u00a01.9, 95% confidence interval 1.5\u20132.3, <jats:italic>P<\/jats:italic>\u00a0&lt;\u00a00.0001) risk of suicide\/suicide attempt during the first 3\u00a0years after diagnosis in patients with hematological malignancies compared to matched controls. Of all hematological malignancies, multiple myeloma was associated with the highest risk (HR\u00a0=\u00a03.4; 2.3\u20135.0, <jats:italic>P<\/jats:italic>\u00a0&lt;\u00a00.0001). Patients with a preexisting psychiatric disorder were at a very high risk of suicide and suicide attempt (HR\u00a0=\u00a023.3; 16.6\u201332.6, <jats:italic>P<\/jats:italic>\u00a0&lt;\u00a00.0001), regardless of type of hematological malignancy. Among patients who committed suicide, 19% were in a palliative phase and 44% were in remission with no active treatment. In conclusion, the risk of suicide and suicide attempt is elevated in patients with hematological malignancies. Certain high\u2010risk patients may benefit from early detection and preventive measures.<\/jats:p>","DOI":"10.1002\/cam4.316","type":"journal-article","created":{"date-parts":[[2014,8,26]],"date-time":"2014-08-26T05:01:23Z","timestamp":1409029283000},"page":"147-154","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":21,"title":["Incidence and risk factors for suicide and attempted suicide following a diagnosis of hematological malignancy"],"prefix":"10.1002","volume":"4","author":[{"given":"Malin","family":"Hultcrantz","sequence":"first","affiliation":[{"name":"Division of Hematology Department of Medicine Karolinska University Hospital Solna and Karolinska Institutet Stockholm Sweden"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tobias","family":"Svensson","sequence":"additional","affiliation":[{"name":"Clinical Epidemiology Unit Department of Medicine Karolinska University Hospital Solna and Karolinska Institutet Stockholm Sweden"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"\u00c5sa R.","family":"Derolf","sequence":"additional","affiliation":[{"name":"Division of Hematology Department of Medicine Karolinska University Hospital Solna and Karolinska Institutet Stockholm Sweden"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sigurdur Y.","family":"Kristinsson","sequence":"additional","affiliation":[{"name":"Division of Hematology Department of Medicine Karolinska University Hospital Solna and Karolinska Institutet Stockholm Sweden"},{"name":"Faculty of Medicine University of Iceland and Department of Hematology Landspitali National University Hospital Reykjavik Iceland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ebba K.","family":"Lindqvist","sequence":"additional","affiliation":[{"name":"Division of Hematology Department of Medicine Karolinska University Hospital Solna and Karolinska Institutet Stockholm Sweden"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Anders","family":"Ekbom","sequence":"additional","affiliation":[{"name":"Clinical Epidemiology Unit Department of Medicine Karolinska University Hospital Solna and Karolinska Institutet Stockholm Sweden"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Fredrik","family":"Granath","sequence":"additional","affiliation":[{"name":"Clinical Epidemiology Unit Department of Medicine Karolinska University Hospital Solna and Karolinska Institutet Stockholm Sweden"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Magnus","family":"Bj\u00f6rkholm","sequence":"additional","affiliation":[{"name":"Division of Hematology Department of Medicine Karolinska University Hospital Solna and Karolinska Institutet Stockholm Sweden"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2014,8,26]]},"reference":[{"key":"e_1_2_7_2_1","doi-asserted-by":"publisher","DOI":"10.1182\/blood-2008-09-179341"},{"key":"e_1_2_7_3_1","doi-asserted-by":"publisher","DOI":"10.1200\/JCO.2006.09.0100"},{"key":"e_1_2_7_4_1","doi-asserted-by":"publisher","DOI":"10.1200\/JCO.2012.42.1925"},{"key":"e_1_2_7_5_1","doi-asserted-by":"publisher","DOI":"10.1056\/NEJMoa011795"},{"key":"e_1_2_7_6_1","doi-asserted-by":"publisher","DOI":"10.1200\/JCO.2011.34.7542"},{"key":"e_1_2_7_7_1","doi-asserted-by":"publisher","DOI":"10.1038\/leu.2014.23"},{"key":"e_1_2_7_8_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.leukres.2012.05.020"},{"key":"e_1_2_7_9_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1600-0609.2012.01831.x"},{"key":"e_1_2_7_10_1","doi-asserted-by":"publisher","DOI":"10.1002\/cncr.22365"},{"key":"e_1_2_7_11_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00520-012-1630-5"},{"key":"e_1_2_7_12_1","doi-asserted-by":"publisher","DOI":"10.1200\/JCO.2007.13.8941"},{"key":"e_1_2_7_13_1","doi-asserted-by":"publisher","DOI":"10.1080\/14034940410019226"},{"key":"e_1_2_7_14_1","doi-asserted-by":"publisher","DOI":"10.1200\/JCO.2004.02.052"},{"key":"e_1_2_7_15_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0959-8049(03)00598-7"},{"key":"e_1_2_7_16_1","volume-title":"Cancer incidence in Sweden 2011 = Cancerf\u00f6rekomst i Sverige 2011","author":"Sverige.
