A case-control study, undertaken to identify reasons for the exceptionally high incidence of bladder cancer among men in the Chicoutimi census division of the province of Quebec, revealed an increased risk associated with employment in the electrolysis department of an aluminum reduction plant. The estimated relative risk was 2.83 (95% confidence interval; 1.06 to 7.54). An interaction was found between such employment and cigarette smoking, resulting in a combined relative risk of 5.70 (95% confidence interval: 2.00 to 12.30). These findings suggest that employment in an aluminum reduction plant accounts for part of the excess of bladder cancer in the region studied.
