对肺癌高危险职业人群进行了１０年前瞻性研究并与同时、同地居民用截缩寿命在法进行对比全、去死因寿命。分析了高危险人群的寿命水平、死亡特征、肺癌死因对寿命的影响。结果表明，高危职业人群的寿命水平低于居民，肺癌死亡居恶性肿瘤死亡之首。去除肺癌死因后，高危职业人群的期望寿命将提高１．３８～１．５８岁，其肺癌导致寿命损耗比当地同性别居民损耗多１．１５岁．对以上结果做了扼要讨论。
A 10-year prospective study was conducted on the high-risk occupational population of lung cancer and compared with the same time, the residents living in the same area used the method of shortening the life expectancy in comparison with the life expectancy. Analysis of the life-threatening level of high-risk groups, the characteristics of death, lung cancer deaths on the impact of life. The results show that the life expectancy of high-risk occupational groups is lower than that of residents, and the death of lung cancer ranks first among malignant tumor deaths. After removing the cause of death from lung cancer, the life expectancy of the high-risk occupational population will increase 1.38 to 1.58 years, and the life span of lung cancer will be 1.15 years more than that of the local same-sex population. The above results are briefly discussed.
