[摘要] 目的：探讨肿瘤标志物联合检测在良、恶性胸腔积液鉴别诊断中的临床意义。方法：采集有胸腔积液患者的血清和胸腔积液样本各165例，其中，恶性胸腔积液患者55例，良性胸腔积液患者110例，用化学发光法检测患者血清和胸腔积液CEA、TSGF的含量。结果：恶性胸腔积液组血清CEA、TSGF的阳性率分别为58.82%和54.29%，胸腔积液CEA、TSGF的阳性率分别为75.76%和70.67%；其中，肿瘤标志物CEA、TSGF血清及胸腔积液的阳性率明显高于良性胸腔积液组，差异有高度统计学意义(P<0.01)；两组含量的检测也得出相似的结果。联合检测血清CEA、TSGF诊断恶性胸腔积液的敏感度为85.71%，特异度为97.80%。结论：肿瘤标志物CEA、TSGF联合检测，对胸腔积液的鉴别诊断有较好的临床价值。

[Abstract] Objective: To study the clinical significance of tumor markers combined assay in the differential diagnosis of pleural effusion. Methods: 165 serum and hydrothorax samples were collected from 165 inpatients with pleural effusion. Among them, 55 patients were suffered with m alignant pleural effusion, and 110 patients with benign pleural effusion. The concentration of carcino-embryonic antigen (CEA), and tumor specific growth factor (TSGF) were determined by chemiluminescence assay. Results: In m alignant pleural effusion group, the positive rates of serum CEA and TSGF were 58.82% and 54.29% respectively, the positive rates of hydrothorax CEA and TSGF were 75.76% and 70.67% respectively. Among them, CEA and TSGF in m alignant group were significantly higher than those in benign pleural effusion group (P<0.01). The content detection also showed similar results. The sensitivity of combined assay with serum TSGF in diagnosing m alignant pleural effusion was 85.71%, with the specificity of 97.80%. Conclusion: Tumor markers of CEA and TSGF have high clinical values in the differential diagnosis of pleural effusion. The combined assay with TSGF is recommended ......
