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 (ELISA)测定 14例结核性和 4 0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 6 7.5 % ,特异性为 85 .7% ,诊断符合率为 72 .2 % ;CEA的敏感性为 5 7.5 % ,特异性为 78.6 % ,诊断符合率为 6 2 .9% ;联合检测胸水TSGF和CEA敏感性为 93% ,特异性为 6 7.4 % ,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

Objective 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 .
