Title Meta-analysis of silicosis and lung cancer
Bibliographic information Dec. 2005, Vol.31, No.6, p.450-458. Illus. 66 ref.
Abstract This study examined the association between silicosis and lung cancer in 31 studies (27 cohort studies and four case-control studies) that reported a measure of association (standardized mortality ratio, relative risk or odds ratio) relating lung cancer to silicosis. Without adjustment for smoking, the analysis indicated that the common standardized mortality ratio (SMR) was 2.45. When the results of the cohorts for which mortality data were adjusted for smoking were pooled, the common SMR was 1.60. In a dose-response analysis, the profusion of small and large opacities found in chest X-rays correlated with the risk of death from lung cancer. Because of biases inherent to observational studies, it is likely that the risk of lung cancer among silicosis patients is overestimated in current literature. There is nevertheless evidence that silicosis and lung cancer are associated.
