铁矿工肺癌病因病例对照研究

A case-control study on causation of lung cancer in iron ore miners.

本研究系在历史前瞻性队列研究基础上,采用同厂矿队列内病例:对照=1:4配比,对接尘、矽肺、吸烟与肺癌之间关系进行了对比分析。结果未发现肺癌发病与接尘、矽肺有直接关系;但结果说明吸烟与肺癌关系密切。

Based on a retrospective cohort study, a nested case-control study had been conducted with case: control=1:4 for exploring relationship among dust exposure, silicosis, smoking and lung cancer. No causation was found among dust exposure, silicosis and lung cancer,but smoking might raise the risk of lung cancer among iron ore miners.
