在回顾性队列研究基础上，对全国１５个省市２０个油毡厂工人肺癌发病情况继续进行前瞻性研究４年。结果表明，混合组和石油组肺癌显著超出对照人群和全国城市居民，ＳＭＲ分别为３．３３（Ｐ＜０．０１），１．７７（Ｐ＜０．０１）和３．４６（Ｐ＜０．０１），１．８８（Ｐ＜０．０１），接触不同种类沥青作业的油毡工人肺癌存在剂量－反应关系。接触人群中非吸烟者的肺癌也显著超量，其肺癌发病具有职业特点，是一种与职业有关的癌症。
Based on the retrospective cohort study, a forward-looking study was conducted on the incidence of lung cancer among 20 linoleum workers in 15 provinces and cities across the country for 4 years. The results showed that lung cancer in the mixed group and the petroleum group significantly exceeded the control population and the urban residents of the country, with SMR of 3.33 (P<0.01), 1.77 (P<0.01), and 3.46 (P<0, respectively). .01), 1.88 (P<0.01). There was a dose-response relationship between lung cancer in linoleum workers exposed to different types of asphalt. The lung cancer among non-smokers who come into contact with the population is also significantly over-proportioned. The onset of lung cancer has occupational characteristics and is a career-related cancer.
