We evaluated associations between multiple myeloma and occupational exposure to six chlorinated solvents: 1,1,1-trichloroethane, trichloroethylene (TCE), methylene chloride (DCM), perchloroethylene, carbon tetrachloride and chloroform.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>In-person interviews obtained occupational histories and information on jobs with likely solvent exposure. We assigned exposure metrics of probability, frequency, intensity and confidence using job-exposure matrices modified by job-specific questionnaire information. We used logistic regression to estimate ORs and 95% CIs for associations between multiple myeloma and ever exposure to each, and any, chlorinated solvent and analysed whether associations varied by duration and cumulative exposure. We also considered all occupations that were given the lowest confidence scores as unexposed and repeated all analyses.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Risk of multiple myeloma was elevated for subjects ever exposed to 1,1,1-trichloroethane (OR (95% CI): 1.8 (1.1 to 2.9)). Ever exposure to TCE or DCM also entailed elevated, but not statistically significant, risks of multiple myeloma; these became statistically significant when occupations with low confidence scores were considered unexposed (TCE: 1.7 (1.0 to 2.7); DCM: 2.0 (1.2 to 3.2)). Increasing cumulative exposure to perchloroethylene was also associated with increasing multiple myeloma risk. We observed non-significantly increased multiple myeloma risks with exposure to chloroform; however, few subjects were exposed.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Evidence from this relatively large case-control study suggests that exposures to certain chlorinated solvents may be associated with increased incidence of multiple myeloma; however, the study is limited by relatively low participation (52%) among controls.<\/jats:p><\/jats:sec>","DOI":"10.1136\/oem.2009.054809","type":"journal-article","created":{"date-parts":[[2010,9,11]],"date-time":"2010-09-11T02:20:40Z","timestamp":1284171640000},"page":"391-399","source":"Crossref","is-referenced-by-count":41,"title":["The relationship between multiple myeloma and occupational exposure to six chlorinated solvents"],"prefix":"10.1136","volume":"68","author":[{"given":"Laura S","family":"Gold","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Patricia A","family":"Stewart","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kevin","family":"Milliken","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mark","family":"Purdue","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Richard","family":"Severson","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Noah","family":"Seixas","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Aaron","family":"Blair","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Patricia","family":"Hartge","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Scott","family":"Davis","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Anneclaire J","family":"De Roos","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2010,9,10]]},"reference":[{"key":"2024052300320264000_68.6.391.1","doi-asserted-by":"publisher","DOI":"10.1200\/JCO.2005.05.021"},{"key":"2024052300320264000_68.6.391.2","doi-asserted-by":"publisher","DOI":"10.1097\/00001648-200111000-00023"},{"key":"2024052300320264000_68.6.391.3","doi-asserted-by":"publisher","DOI":"10.1002\/(SICI)1097-0274(199701)31:1<21::AID-AJIM4>3.0.CO;2-#"},{"key":"2024052300320264000_68.6.391.4","doi-asserted-by":"publisher","DOI":"10.1002\/ijc.11351"},{"key":"2024052300320264000_68.6.391.5","doi-asserted-by":"publisher","DOI":"10.1136\/oem.2005.020453"},{"key":"2024052300320264000_68.6.391.6","first-page":"742","article-title":"Cancer risks in painters: study based on the New Zealand Cancer Registry","volume":"47","author":"Bethwaite","year":"1990","journal-title":"Br J Ind Med"},{"key":"2024052300320264000_68.6.391.7","doi-asserted-by":"crossref","first-page":"270","DOI":"10.5271\/sjweh.320","article-title":"Mortality and cancer incidence among Swedish paint industry workers with long-term exposure to organic solvents","volume":"24","author":"Lundberg","year":"1998","journal-title":"Scand J Work Environ Health"},{"key":"2024052300320264000_68.6.391.8","doi-asserted-by":"crossref","first-page":"629","DOI":"10.1002\/ajim.4700230410","article-title":"A case-control study of multiple myeloma and occupation","volume":"23","author":"Demers","year":"1993","journal-title":"Am J Ind Med"},{"key":"2024052300320264000_68.6.391.9","doi-asserted-by":"publisher","DOI":"10.1136\/oem.57.3.188"},{"key":"2024052300320264000_68.6.391.10","doi-asserted-by":"publisher","DOI":"10.1158\/1055-9965.EPI-08-0343"},{"key":"2024052300320264000_68.6.391.11","doi-asserted-by":"publisher","DOI":"10.1097\/00001648-200101000-00014"},{"key":"2024052300320264000_68.6.391.12","unstructured":"De Roos AJ Baris D Weiss NS .
