【摘要】 本文报道2383例石棉工人的肺癌发生率,采用回顾队列调查法,追踪10年（1972—1981）。结果全死亡SMR_1.13,没有显著性差异,而肺癌SMR_2.66,RR_10.36均有显著性差异（P<0.05）。发生肺癌的潜伏期平均为23.8年,主要发生在高石棉粉尘浓度的工种,表明肺癌的发生与接触石棉有关。更多还原

【Abstract】 A retrospective cohort study of lung cancer in 2383 asbestos workers was carried out from January 1,1972 to December 31,1981.Result of the study showed that the mortality of the study group was not significantly different from that of the control group (SMR 1.13),but the prevalence of lung cancer (SMR 2.66,RR 10.36)was significantly greater(P<0.05).The average latent period of lung cancer was 23.8 years.Those workers who developed lung cancers worked mainly at workplaces with higher asbestosdust concentrations,suggested thatthere was a relationship between asbestos dust exposure and death of the lung cancer.更多还原
