目的 了解石棉作业工人与恶性肿瘤发病的关系。方法 对某市石棉厂石棉作业工人 1 96 4年 1月 1日～ 2 0 0 2年 1 2月 31日期间全死亡、肿瘤发病及死亡情况进行回顾性调查。结果 全死因死亡率为2 97.7/1 0万 ,全恶性肿瘤死亡率为 1 0 2 .0 87/1 0万 ,特发部位恶性肿瘤死亡率为 6 1 .39/1 0万。与当地人口肿瘤年龄别死亡率进行比较 ,显示两者差异显著 (P <0 .0 0 1 )。腹膜恶性间皮瘤 1例 ,接尘工龄为 4年 ,潜伏期2 4年。肺癌 3例 ,接尘工龄平均 1 8年 ,潜伏期平均 2 3年。结论 石棉可导致特发部位恶性肿瘤
Objective To understand the relationship between asbestos workers and the incidence of malignant tumors. Methods The asbestos workers in a asbestos factory in a city were retrospectively investigated for the complete death, the incidence of cancer and their deaths between January 1, January 19, January 31, 2002 and January 31, 2002. Results The all-cause mortality rate was 2 97.7 / 100 000, the total malignant tumor death rate was 102.07 / 100 000 and the malignant tumor death rate was 61.39 / 100 000 in the idiopathic part. Compared with the age-specific mortality rate of local population, the difference between the two groups was significant (P <0.01). 1 case of peritoneal malignant mesothelioma, dust-dependent work for 4 years, the incubation period of 24 years. 3 cases of lung cancer, an average of 18-year service workers, the incubation period of an average of 23 years. Conclusion Asbestos can cause idiopathic malignancies
