Title Study of cancer incidence among 8530 male workers in eight Norwegian plants producing ferrosilicon and silicon metal
Bibliographic information Sep. 1999, Vol.56, No.9, p.625-631. 38 ref.
Abstract To examine the association between cancer incidence and duration of work among employees in Norwegian plants producing ferrosilicon and silicon metal, cases of cancer were obtained from The Cancer Registry of Norway. The numbers of various cancers were compared with expected figures calculated from age and calendar time specific rates for Norwegian men during the same period. Internal comparisons of rates were performed with Poisson regression analysis. A total of 832 cases of cancer were observed against 786 expected (standardized incidence ratio (SIR) = 1.06). Among the furnace workers an increased incidence of lung cancer (SIR 1.57) and testicular cancer (SIR 2.30) was found. Internal comparisons of rates among the rural furnace workers showed a positive trend between incidence of lung cancer and duration of work of 1.05/work-year. Excess cases of prostate and kidney cancer were found among blue collar non-furnace workers, in particular among the mechanics. Results suggest associations between furnace work and lung and testicular cancer, and between non-furnace work and prostate cancer.
