ABSTRACT
OBJECTIVE: To analyze the clinical manifestations and diagnostic points of patients with peritoneal mesothelioma caused by occupational asbestos. METHODS: The clinical data of a female patient with peritoneal mesothelioma caused by occupational asbestos and the diagnosis of occupational diseases were retrospectively analyzed. RESULTS: In 2016, the patient was diagnosed and treated in a number of hospitals in a province due to chest and back pain, persistent cough, suffocation, and foamy sputum. After laparoscopic surgery, the peritoneal biopsy was taken for pathological analysis and diagnosed as peritoneal mesothelioma. In December 2016, she died due to a worsening of her condition and lung infection. The patient′s family requested occupational disease diagnosis in May 2017. After investigation and verification by the local occupational disease diagnosis agency and the Bureau of Industry and Information Technology, it was clear that the patient had a history of occupational exposure to asbestos for a total of 23 years and two months. In July 2018, she was retrospectively diagnosed as an occupational tumor(mesothelioma caused by asbestos). CONCLUSION: A clear history of occupational exposure to asbestos and histopathological examination are helpful for the diagnosis of occupational tumors(mesothelioma caused by asbestos).
ABSTRACT
OBJECTIVE: To summarize and analyze the diagnostic ideas of new occupational lung tumors in Guangdong Province.METHODS: According to the Law of the People′s Republic of China on the Prevention and Control of Occupational Disease and the GBZ 94-2002 Diagnostic Criteria of Occupational Cancer, the key diagnostic points of 6 new occupational lung tumors diagnosed in Guangdong Province from 2010 to 2011 were analyzed. RESULTS: There were 9 cases of 6 new kinds of new occupational tumors were diagnosed in Guangdong Province in 2010-2011. The cases included 3 occupational lung cancer of coke oven workers, 2 occupational lung cancer caused by asbestos, 1 occupational mesothelioma caused by asbestos, 1 occupational lung cancer caused by arsenate, 1 occupational lung cancer caused by chromate salt, and 1 occupational lung cancer caused by asphalt. During the process, the diagnosis was based on the principles of the comprehensive analysis and the attribution diagnosis, combined with occupational history, occupational disease hazard exposure history, clinical data and auxiliary examination results. If the patients were diagnosed with a primary tumor, the patients′ exposure history to occupational carcinogens should be tracked, traced and confirmed, and the diagnosis should be confirmed by referring to the list of occupational carcinogens and literature reports of the International Labor Organization, and not limited to only the personnel in a particular industry. CONCLUSION: During the diagnostic process of occupational tumors, attention should be paid to confirm the exposure history of occupational carcinogen. The key is to determine the exposure of corresponding occupational carcinogen, the route and the time of exposure and the incubation period.
