作者研究了加拿大魁北克沙维尼根聚氯乙烯厂工人中1955年以来诊断的十例肝血管肉瘤。本文着重研究肝血管肉瘤患者的职业史、饮酒和吸烟习惯以及肿瘤的组织病理类型。患者均为男性,死亡年龄为41～61岁,平均死亡年龄为50.5岁。不吸烟者1例;中等吸烟者5例,每天吸烟平均为20支或20支以下;严重吸烟者4例,每天吸烟一包或一包以上。中等吸烟和不吸烟者中发现肿瘤的年龄平均为47岁,严重吸烟者平均年龄为54岁。由此认为吸烟与肝血管肉瘤发病无直接关系。此十例患者饮酒都很少,只有2例每天喝一瓶多啤酒。也未发现饮酒与氯乙烯工人肝血管肉瘤有什么关系。
The authors studied ten hepatic angiosarcomas diagnosed since 1955 in PVC plant workers in Savignane, Quebec, Canada. This article focuses on occupational history, alcohol consumption and smoking habits, and histopathological types of the tumor in patients with hepatic angiosarcoma. Patients were male, the death age was 41 to 61 years old, the average age of death was 50.5 years old. 1 case of non-smoker; 5 cases of moderate smokers, the average daily smoking of 20 or less; 4 smokers in 4 cases, a pack of cigarettes a day or more. The median age at which tumors were found in moderately smokers and non-smokers was 47 years and that in serious smokers was 54 years. So that the incidence of smoking and hepatic angiosarcoma is not directly related. The ten patients had very little alcohol consumption and only two had more than a bottle of beer per day. Also did not find alcohol and vinyl chloride workers hepatic angiosarcoma have anything to do.
