许多学者致力于胸腔积液中癌胚抗原(CEA)的测定来鉴别良,恶性病变。业已证明,恶性胸腔积液中的CEA 值比良性胸腔积液高。本文报道213例.其中恶性胸腔积液为140例。良性胸腔积液为73例。胸腔积液中的CEA 用放射免疫测定法检查。结果发现,良性胸腔积液CEA平均含量为8.9±9.7ng/ml(中位数6ng/ml);间皮瘤性胸腔积液2.5±3.4ng/ml(中位数1.5ng
Many scholars committed to the determination of carcinoembryonic antigen (CEA) in pleural effusion to identify benign and malignant lesions. It has been demonstrated that CEA in malignant pleural effusions is higher than in benign pleural effusions. This article reports 213 cases, of which 140 cases of malignant pleural effusion. 73 cases of benign pleural effusion. CEA in pleural effusion was examined by radioimmunoassay. The results showed that the average content of CEA in benign pleural effusion was 8.9 ± 9.7ng / ml (median 6ng / ml); mesothelioma pleural effusion 2.5 ± 3.4ng / ml (median 1.5ng
