目的分析某焦化厂近40年间焦炉工人肺癌的发病特征。方法收集、整理该焦化厂1970—2008年间焦炉工人肺癌的发病资料,利用SPSS18.0软件并对其发病年龄、潜伏期、生存期及病理特点等进行描述性分析。结果①67例焦炉工人肺癌病例主要分布于炉顶工段,占62.7%;其次为炉侧区,占26.9%;②发病平均年龄为61.4岁,大都集中在50～70岁;③焦炉工人肺癌的潜伏期平均为35a,生存期较短,1、3、5a生存率分别为48.6%、12.9%、8.6%;④病理类型以腺癌为主,占55%;其次为鳞癌,占41%。结论焦炉工人肺癌主要分布于炉顶工段,其潜伏期较长而生存期较短,腺癌占的比例较大。该焦化厂近年来肺癌发病人数增加较快,应当引起重视。
Objective To analyze the incidence of lung cancer in coke oven workers in a coking plant over the past 40 years. Methods The incidence of lung cancer in coke oven workers during 1970-2008 was collected and sorted out. Descriptive analysis was made on the age of onset, incubation period, survival time and pathological features using SPSS18.0 software. Results ①The cases of lung cancer in 67 coke oven workers were mainly found in the top of the furnace, accounting for 62.7%; followed by the furnace side, accounting for 26.9%; ② The average age of onset was 61.4 years old, mostly concentrated in the 50-70 years old; ③Coke oven workers lung cancer The average survival time was 35.6%, the average survival time was 35.6%, and the survival rate was 48.6%, 12.9% and 8.6% respectively; ④ The pathological types were adenocarcinoma, accounting for 55%; followed by squamous cell carcinoma, accounting for 41% . Conclusion Coke oven workers are mainly located in the top of the lung cancer work section, longer latency and shorter survival, adenocarcinoma accounted for a larger proportion. The coking plant in recent years the incidence of lung cancer increased rapidly, deserves attention.
