目的探讨胸水细胞学与胸水癌胚抗原(CEA)联合检测在肺癌胸腔积液诊断中的价值。方法回顾肺癌胸腔积液脱落细胞学的诊断,结合病理组织学检查,分析其诊断价值。检测肺癌胸腔积液CEA浓度分析判断其诊断价值。结果细胞学检查阳性率为76.19%。胸水CEA阳性率为80.95%。两者联合检测阳性率95.23%。结论胸水细胞学是检测肺癌胸腔积液的重要手段,胸水CEA检测在肺癌胸腔积液中的阳性率较高,可作为筛选指标。两者联检可提高敏感性。
Objective To investigate the value of combined detection of pleural fluid cytology and pleural fluid carcinoembryonic antigen (CEA) in the diagnosis of pleural effusion in lung cancer. Methods The diagnosis of pleural effusion cytology in lung cancer was reviewed. Combined with histopathological examination, the diagnostic value was analyzed. Detection of CEA concentration in lung cancer pleural effusion to determine its diagnostic value. Results The positive rate of cytology was 76.19%. Pleural effusion CEA positive rate was 80.95%. The combined detection rate of the two was 95.23%. Conclusions Pleural fluid cytology is an important method to detect pleural effusion in lung cancer. The positive rate of pleural fluid CEA in pleural effusion of lung cancer is high, which can be used as a screening index. Joint detection of the two can increase the sensitivity.
