✦ Synopsis
Background: Male age-adjusted lung cancer mortality rate is high in Rosario City, Argentina (62.7 per 100,000). Methods: Case-control study involving interviews with 367 male lung cancer patients and 576 controls. Results: The histological distribution detected was: squamous cell 39%, adenocarcinoma 34%, small cell carcinoma 13%, and other or no speci®ed cell type 14%. When comparing with the group unlikely to be exposed to occupational carcinogens, a 60% increase in risk was observed for the remaining occupations (P `0.008). Risks were high for drivers (OR 1.9, CI: 1.1±4.0), construction (OR 2.5, CI: 1.0±5.9), and agricultural workers also (OR 1.8, CI: 1.1±3.1). In regard to squamous cell carcinoma, increased risks were observed in the metal industry, particularly in welders (OR 2.9, CI: 1.0±10.1) and mechanics (OR 1.8, CI: 0.9±4.2). Smoking was not a substantial confounding effect. Conclusions: Occupational exposures partly account for the high lung cancer mortality rate among male residents of Rosario City. Am. J. Ind. Med. 36:437±443, 1999.
