胸腔积液临床常见,其病因繁多,其中癌性胸腔积液约占整个胸腔积液的25％,41.5％癌性胸腔积液系由支气管肺癌所致。为了提高对癌性胸腔积液的认识,本文收集我院1974年至1990年经X线检查和临床综合确诊的34例支气管肺癌伴胸腔积液者进行回顾性分析。一般资料一、性别与年龄:癌性胸腔积液34例。男19例,女15例,年龄46～87岁。平均68岁。 Pleural effusion is common clinically, and its causes are numerous. Among them, cancerous pleural effusion accounts for about 25% of the total pleural effusion. 41.5% of cancerous pleural effusions are caused by bronchial lung cancer. In order to improve the understanding of cancer pleural effusion, we collected 34 cases of bronchial lung cancer with pleural effusion from 1974 to 1990 by X-ray examination and clinical diagnosis. General Information 1. Sex and Age: 34 cases of cancerous pleural effusion. There were 19 males and 15 females, aged 46-87 years old. Average 68 years old.
