在对四川省1950～1986年尘肺流行病学调查中发现,尘肺中癌瘤死亡率为1566/10万,在尘肺死因中居第4位,占死亡病例的6.52％,其中均以石棉肺为最高,且都有随尘肺期别上升而下降的趋势。在对1970—1986年间尘肺回顾性队列研究中,分别以全国和四川省普通人群为对照,按年龄别计算其癌瘤的SMR,尘肺(包括石棉矽肺、肺和煤工尘肺)中,肺癌危险性明显增高,石棉肺又显著高于其它类型尘肺。结果认为,矿物粉尘和尘肺与肺癌有着密切的关系,应予高度警惕和重视,然而除石棉外,矽尘和煤尘致人类肺癌的作用尚须进一步探讨。
In the epidemiological survey of pneumoconiosis from 1950 to 1986 in Sichuan Province, it was found that the death rate of cancer in pneumoconiosis was 1566/100000, the fourth in pneumoconiosis, accounting for 6.52% of the deaths, of which the asbestosis was the highest , And all have the tendency to fall with pneumoconiosis. In the retrospective cohort study of pneumoconiosis during 1970-1986, the risk of lung cancer was calculated as SMR, pneumoconiosis (including asbestos silicosis, lung and coal worker pneumoconiosis) by age-specific comparisons of the general population in the country and in Sichuan Province, respectively Sex was significantly higher, asbestosis was significantly higher than other types of pneumoconiosis. The results suggest that mineral dust and pneumoconiosis have a close relationship with lung cancer and should be highly vigilant and valued. However, the role of silica and coal dust in causing human lung cancer needs to be explored further.
