我院自1992～1996年用放射免疫法测定48例已明确诊断的良恶性胸水中癌胚抗原（CEA）、铁蛋白(Ft)值,发现可提高对胸水性质的鉴别。 资料和方法 一、资料:胸水48例（男36,女12）,年龄22～79岁。其中恶性胸水20例（包括肺癌胸膜转移12例,乳腺癌胸膜转移3例,白血病胸膜浸润2例,Ⅳ期淋巴瘤3例）;良性胸水28例（包括结核性胸膜炎20例,肝肾综合征5例,红斑狼疮性胸水2例,化脓性胸水1例）。所有病例均经X光胸片、胸部CT检查,部分病例经纤维支气管镜活检或胸水中找到肿瘤细胞而确诊。
In our hospital from 1992 to 1996, radioimmunoassay was used to determine the CEA and Ft values in 48 benign and malignant pleural effusions that were diagnosed. It was found that the identification of pleural effusions could be improved. Materials and Methods First, information: 48 cases of pleural effusion (male 36, female 12), aged 22 to 79 years old. There were 20 cases of malignant pleural effusion (including 12 cases of lung cancer pleural metastasis, 3 cases of pleural metastases of breast cancer, 2 cases of leukemia pleural infiltration, and 3 cases of stage IV lymphoma); 28 cases of benign pleural effusion (including 20 cases of tuberculous pleurisy, hepatorenal syndrome) Five patients had lupus erythematosus in 2 cases and purulent pleural effusion in 1 case). All cases were examined by X-ray chest and chest CT. Some cases were diagnosed by fiberoptic bronchoscopy biopsy or finding tumor cells in pleural fluid.
