目的为摸清煤工尘肺并发肺癌患者死亡情况,研究煤工尘肺与肺癌的关系,进一步做好煤矿尘肺病防治工作。方法对煤工尘肺及其并发肺癌病例资料进行回顾性调查分析。结果 1393例煤工尘肺死亡患者死于肺癌148例,占死亡病例的10.62%。经对各期别尘肺患者肺癌发病率进行比较,差异无统计学意义(χ2=5.572,P>0.05)。各期煤工尘肺肺癌死亡年龄比较差异无统计学意义(F=0.60,P>0.05)。煤工尘肺肺癌患者接害工龄以10～29年的居多,占81.76%,平均井下接尘(19.73±7.64)年;按煤矿主要工种划分,148例尘肺肺癌患者按接害工种比较各接害工种的平均接害工龄差异有统计学意义(F=3.53,P<0.01)。结论煤矿工人接触粉尘与肺癌发病密切相关,做好粉尘综合防治,降低尘肺病及尘肺肺癌患者的发生,是煤矿职业病防治重点。
Objective To find out the death of coal worker’s pneumoconiosis complicated with lung cancer, to study the relationship between coal worker’s pneumoconiosis and lung cancer, and to make further prevention and control of coal mine pneumoconiosis. Methods The data of coal workers’ pneumoconiosis and its associated lung cancer were retrospectively analyzed. Results A total of 148 cases of lung cancer died of pneumoconiosis in 1393 coal workers, accounting for 10.62% of the deaths. After comparing the incidence of lung cancer patients with pneumoconiosis, the difference was not statistically significant (χ2 = 5.572, P> 0.05). There was no significant difference in the death ages of pneumoconiosis patients from coal workers in each phase (F = 0.60, P> 0.05). Coal miners with pneumoconiosis and lung cancer received the majority of their length of service from 10 to 29 years, accounting for 81.76% of the average downhole dust (19.73 ± 7.64) years. According to the classification of major types of coal mines, 148 cases of pneumoconiosis were compared according to their types of work The average difference in occupational occupational differences was statistically significant (F = 3.53, P <0.01). Conclusion Coal miners exposed to dust and lung cancer are closely related to do a good job of integrated dust control and reduce pneumoconiosis and pneumoconiosis patients is the focus of prevention and control of coal mine occupational diseases.
