接尘工人肺癌的病理学调查

Pathological Survey of Lung Cancer in Dust-exposed Workers

本文集中我国各地区1960-1990年接尘工人尸检1000例,以非接尘男性尸检612例做对照,对尘肺肺癌的发病率和病理进行分析研究。结果:(1)接尘工人尸检肺癌发病率为17.2%,比对照组(3.16%)显著超高,占全身各器官癌病之首;(2)石棉肺尸检肺癌率最高(26.92%),矽肺(18.5%)与煤工尘肺(16.79%)相近;(3)职业上,煤矿、金属矿和石棉矿是我国尘肺肺癌的三大主要工种,接尘工龄以11～20年段发病最多(55.1%);(4)病理类型依次为腺癌(含肺泡细胞癌)、鳞癌、未分化癌,其中石棉肺一半以上为腺癌。

A survey was made on 1000 autopsy cases during 1960-1990 period of the dust-exposed workers collected from nation-wide regions, and 672 autopsy cases of nondust-exposed males as control. The results showed that, 1. the incidence of lung cancer in the dust-exposed workers was significantly higher tha the control (17.2% vs 3.16%), and that in the asbestosis group was the highest (26.9%) ; 2. occupationally, coal and metal mines, as well as asbestos mills and mines were the three main jobs liable to lung cancer; 3.pathologically, the lung cancer was classified into adenocarcinoma (including alveolar carcinoma), squamous cell carcinoma, undifferentiated carcinoma in order, and more than half of the asbestosis patients subjected to adenocarcinoma.
