卷烟厂男性职工恶性肿瘤死亡回顾性队列研究

为分析烟草尘对卷烟厂男性职工恶性肿瘤死亡专率的影响，采用回顾性队列研究的方法，对河南、黑龙江两省某两卷烟厂１９８２～１９９４年间在册的男性职工进行恶性肿瘤死因分析。以队列成员中的非暴露于烟草尘组为内对照，比较两组间的恶性肿瘤死亡专率的差异。结果表明男性职工暴露组的恶性肿瘤死亡专率显著高于非暴露组，且可能存在剂量－效应关系。提示接触烟草尘可能是恶性肿瘤死亡的危险因素，且吸烟和接触烟草尘对上述疾病可能存在协同作用。

我国北方两卷烟厂职工死亡回顾性调查

为分析烟草尘对卷烟厂职工恶性肿瘤、呼吸系疾病死亡专率的影响，采用回顾性队列研究的方法，对河南、黑龙江两省某两卷烟厂１９８２～１９９４年间在册的职工进行恶性肿瘤、呼吸系疾病死因分析。以队列成员中的非暴露于烟草尘组为内对照，比较两组间的各死因死亡专率的差异。结果表明：男、女职工暴露组的恶性肿瘤、呼吸系疾病死亡专率均显著高于非暴露组。按接触烟草水平分为非接触组、低剂量接触组和高剂量接触组分析发现：恶性肿瘤、呼吸系疾病死亡与其暴露烟草尘水平可能存在剂量－效应关系。提示：接触烟草尘可能是恶性肿瘤、呼吸系疾病死亡的危险因素。吸烟和接触烟草尘的协同作用分析表明：吸烟和接触烟草尘对恶性肿瘤、呼吸系疾病可能存在协同作用。

Smoking imputation and lung cancer in railroad workers exposed to diesel exhaust

BACKGROUND: An association between diesel exhaust exposure and lung cancer mortality in a large retrospective cohort study of US railroad workers has previously been reported. However, specific information regarding cigarette smoking was unavailable. METHODS: Birth cohort, age, job, and cause of death specific smoking histories from a companion case-control study were used to impute smoking behavior for 39,388 railroad workers who died 1959-1996. Mortality analyses incorporated the effect of smoking on lung cancer risk. RESULTS: The smoking adjusted relative risk of lung cancer in railroad workers exposed to diesel exhaust compared to unexposed workers was 1.22 (95% CI = 1.12-1.32), and unadjusted for smoking the relative risk was 1.35 (95% CI = 1.24-1.46). CONCLUSIONS: These analyses illustrate the use of imputation in record-based occupational health studies to assess potential confounding due to smoking. In this cohort, small differences in smoking behavior between diesel exposed and unexposed workers did not explain the elevated lung cancer risk.     

Epidemiologic study of cancer mortality among Israeli asphalt workers

BACKGROUND: We describe the results of a cancer mortality study among asphalt workers in Israel. METHODS: Personal identifiers and employment histories of 2,176 workers were extracted from company records. RESULTS: Mortality from all malignant neoplasms was significantly reduced in the whole cohort (SMR 0.68, 95% confidence interval (CI) 0.56-0.83). SMR for lung cancer was elevated in workers exposed to bitumen (SMR 1.05, 95% CI 0.62-1.66). No significant elevation or reduction in mortality was observed in relation to a specific site. SMRs for lung cancer was higher among ever exposed to bitumen than among unexposed. There was no association between lung cancer risk and estimated exposure to bitumen fume, and no dose-response was apparent. CONCLUSIONS: While the results of this cohort study indicate a slightly increased SMR for lung cancer, it did not produce evidence of a causal link between lung cancer and exposure to bitumen fume.     

Mortality experience of haematite mine workers in China.

The mortality risk of iron ore (haematite) miners between 1970 and 1982 was investigated in a retrospective cohort study of workers from two mines, Longyan and Taochong, in China. The cohort was limited to men and consisted of 5406 underground miners and 1038 unexposed surface workers. Among the 490 underground miners who died, 205 (42%) died of silicosis and silicotuberculosis and 98 (20%) of cancer, including 29 cases (5.9%) of lung cancer. The study found an excess risk of non-malignant respiratory disease and of lung cancer among haematite miners. The standardised mortality ratio for lung cancer compared with nationwide male population rates was significantly raised (SMR = 3.7), especially for those miners who were first employed underground before mechanical ventilation and wet drilling were introduced (SMR = 4.8); with jobs involving heavy exposure to dust, radon, and radon daughters (SMR = 4.2); with a history of silicosis (SMR = 5.3); and with silicotuberculosis (SMR = 6.6). No excess risk of lung cancer was observed in unexposed workers (SMR = 1.2). Among current smokers, the risk of lung cancer increased with the level of exposure to dust. The mortality from all cancer, stomach, liver, and oesophageal cancer was not raised among underground miners. An excess risk of lung cancer among underground mine workers which could not be attributed solely to tobacco use was associated with working conditions underground, especially with exposure to dust and radon gas and with the presence of non-malignant respiratory disease. Because of an overlap of exposures to dust and radon daughters, the independent effects of these factors could not be evaluated.

Mortality in a cohort of pentachlorophenol manufacturing workers, 1940–1989

Mortality in a cohort of 770 workers with potential pentachlorophenol (PCP) exposure was evaluated from 1940 through 1989. The study cohort is a subset of a larger cohort of workers with potential exposure to higher chlorinated dioxins. Total mortality and cancer mortality, in the PCP cohort were slightly lower than expected in comparison to the U.S. white male population. There were 229 total deaths with 242.5 expected (SMR = 94, 95% confidence interval 83–108), and 50 cancer deaths with 52.6 expected (SMR = 95, 95% confidence interval 71–125). In comparison with unexposed employees, the risk ratio for total mortality was 1.03 (95% confidence internal 0.90–1.17), and the risk ratio for all cancer mortality was 0.95 (95% confidence interval 0.71–1.26). In most cause of death categories of a priori interest no deaths were observed in the cohort. A small excess of other and unspecified lymphopoietic cancer deaths was observed but did not appear to be related to exposure. Excesses of deaths due to cancer of the kidney, gastric and duodenal ulcer, cirrhosis of the liver, and all accidents were observed in comparison with the U.S. white male population and with unexposed employees. These were associated with increasing estimated cumulative PCP exposure after lagging exposures by 5 and 15 years. Despite the limited size and the generally favorable total mortality experience of the cohort, it was concluded that cohort members may have incurred increased risk of death due to some specific causes. The risks could not, however, be attributed conclusively to PCP exposure and may have been associated with other occupational and nonoccupational factors. Additional mortality surveillance of this cohort will be performed. © 1996 Wiley-Liss, Inc.
