本文通过煤矿工人肺癌病例对照研究,探讨接尘与肺癌的关系,为研究煤工肺癌病因提供依据。资料来源和调查方法一、调查对象的选择自1979年开始,我局即建立有死亡报告和登记制度。为了保证病例与对照的可比性,我们选择了人口居住比较集中的洪山煤矿作为调查点,然后到工会、家属委员会将1980～1989年间登记死亡者作进一步的核实,确认无误后选为调查对象。病例组:该煤矿1980～1989年间确诊为肺癌死亡的正式男性职工64例。年龄42～78岁。属Ⅰ级诊断者49例(76.6%),Ⅱ级诊断者15例(23.4%)。
In this paper, coal miners lung cancer case-control study to explore the relationship between dust and lung cancer, in order to study the cause of coal-based lung cancer provide the basis. Sources of information and survey methods I. Selection of respondents Since 1979, our bureau has established a death report and registration system. In order to ensure the comparability of cases and controls, we chose Hongshan Coal Mine, which has a relatively concentrated population, as an investigation point. After that, we went to the trade union and the family committee to further verify the registered deaths from 1980 to 1989. Case Group: The coal mine was diagnosed in 64 cases of formal male workers who died of lung cancer from 1980 to 1989. Age 42 ~ 78 years old. There were 49 cases (76.6%) of grade Ⅰ diagnosed, 15 cases (23.4%) of grade Ⅱ diagnosed.
