Abstract Objectives This study estimated the risk of occupational exposure for lung cancer in the metropolitan region of Sao Paulo, the largest urbanized and industrialized area in Brazil.Methods In this hospital-based case-referent study of 398 cases and 860 referents, the cases were matched to referents according to age, gender, and hospital and personally interviewed for information on lifetime job history, smoking habits, passive smoking exposure, cancer in relatives, socioeconomic status, and migratory history. The analysis concerned industrial titles and occupational categories. With the use of a job-exposure matrix, exposure to asbestos, polynuclear aromatic hydrocarbons, arsenic, dust, nickel and chromium was assessed.Results For the men in the 56 industrial and 122 occupational categories examined, an excess risk of lung cancer was found in the machinery industry [odds ratio (OR) 1.62, 95% confidence interval (95% CI) 1.02-2.55). In pottery manufacturing the risk (OR 2.21, 95% CI 1.00-4.87) was increased for workers exposed greater than or equal to 10 years (OR 6.43, 95% CI 1.12-37.01). Textile workers employed for greater than or equal to 10 years with a latency of greater than or equal to 40 years had an elevated risk (OR 21.93, 95% CI 1.96-245.0). In the analysis using the job-exposure matrix no risk was detected for the specific lung cancer carcinogens examined. For the women, no significantly elevated risk was observed.Conclusions The results of this study revealed risks of lung cancer for men in the machinery industry and for pottery and textile workers with long-term exposure.
