恶性肿瘤相关物质及CEA的联合检测对鉴别结核性和恶性胸腔积液的临床价值

目的：探讨胸水中恶性肿瘤相关物质(TSGF)与癌胚抗原(CEA)联合检测对鉴别结核性和恶性胸腔积液的价值。方法：采用酶联免疫吸附法(ELlSA)测定14例结核性和40例恶性胸腔积液患者胸水TSGF和CEA的含量。结果：恶性胸腔积液患者胸水TSGF和CEA平均水平均高于结核性胸腔积液患者；TSGF诊断恶性胸腔积液中的敏感性为67．5％，特异性为85．7％，诊断符合率为72．2％；CEA的敏感性为57．5％，特异性为78．6％，诊断符合率为62．9％；联合检测胸水TSGF和CEA敏感性为93％，特异性为67．4％，诊断符合率为88．9％。结论：联合检测胸水中TSGF与CEA水平可提高对恶性胸腔积液诊断的敏感性与诊断效率；对于鉴别结核性和恶性胸腔积液具有重要价值。

Clinical value of tumor supplied group of factor combined with CEA in diagnosing tuberculosis pleural effusion and malignant pleural effusion]

OBJECTIVES: To determine the clinical value of tumor supplied group of factor (TSGF) combined with carcinoembryonic antigen (CEA) in diagnosing tukerculosis pleural effusion and malignant pleurul effusion. METHODS: TSGF and CEA were detected by ELISA in 14 patients with tuberculosis pleural effusion and 28 patients with malignant pleural effusion. RESULTS: The average levels of TSGF and CEA in patients with malignant pleural effusion were higher than those with tuberculosis pleural effusion. The diagnostic sensitivity of TSGF and CEA in the malignant pleural effusion was 67.5% and 57.5%, the specificity was 85.7% and 78.6%, and the agreement rate was 72.2% and 62.9% respectively; while the sensitivity, specificity and agreement rate of TSGF combined with CEA were 93%, 67.4%, and 88.9%. CONCLUSION: The sensitivity and agreement rate of TSGF combined with CEA are higher than those of either of the two methods. TSGF combined with CEA is important in differentiating tuberculosis and malignant pleural effusion.
