Abstract:
Objective: To study the pathological types of lung cancer caused by coke oven emissions and analyze the correlation between different exposure levels. Methods: In October 2020, the relevant data of 86 confirmed cases of lung cancer caused by coke oven emissions (including basic information of patients, relevant occupational exposure and clinical data) were collected, The workers were grouped according to the different COEs concentrations in their posts: workers in auxiliary posts were taken as the low exposure group (11 persons) , The workers at coke side and furnace bottom are the medium exposure group (14 persons) , and the workers at furnace top are the high exposure group (61 persons) , and the correlation between pathological types of lung cancer and different exposure levels was analyzed. Results: There was no significant difference in age and length of service among the groups (P>0.05) ; The number of lung cancer cases and pathological types among workers in each group were statistically significant (P=0.044) . After adjusting for interference factors, the number of undifferentiated cancers (mainly small cell lung cancer) increased with the increase of exposure level, with a statistically significant difference (P=0.001) . The incidence of lung cancer increased gradually with the length of service, and the incidence rate of lung cancer among workers of different working ages was statistically significant (P<0.05) . Conclusion: Undifferentiated small cell carcinoma is the most common pathological type of lung cancer caused by coke oven emissions, and the incidence of lung cancer tends to increase with the length of service.
