OBJECTIVE
To investigate incidence of malignant tumor in workers exposed to dust in a mine during the past 30 years.
METHODS
A retrospective cohort study was conducted in 16,711 workers exposed to dust and 7,598 non-exposed workers.
RESULTS
Incidence of lung cancer in exposed workers ranked the first place, whth an SMR of 2.648, as compared with that of non-exposed workers. Incidence of lung cancer in the dust-exposed workers with a longer duration of employment was significantly higher than in those with a shorter one. Incidence of lung cancer in exposed workers with a wetoperation mode was lower than that in those with dry-operation mode.
CONCLUSION
Malignant tumor, especially lung cancer, occurred more frequently in the workers exposed to dust, which could be a potential risk factor contributing to carcinogenesis.
目的
调查某矿山过去30年接触粉尘工人的恶性肿瘤发病率。
方法
对16711名接触粉尘工人和7598名非接触粉尘工人进行回顾性队列研究。
结果
与非接触粉尘工人相比，接触粉尘工人的肺癌发病率位居首位，标准化发病比（SMR）为2.648。就业年限较长的接触粉尘工人的肺癌发病率明显高于就业年限较短的工人。采用湿式作业方式的接触粉尘工人的肺癌发病率低于采用干式作业方式的工人。
结论
接触粉尘工人恶性肿瘤尤其是肺癌的发生率较高，这可能是导致癌症发生的潜在危险因素。
