[摘要]目的目前恶性胸腔积液确诊存在一定困难,寻找新的辅助诊断标志至关重要。本研究拟探讨胸水癌胚抗原(CEA)与血清 CEA 比值对恶性胸腔积液的诊断价值。方法本研究纳入南京医科大学附属南京医院呼吸与危重症医学科2017年1月1日至2018年12月31日胸腔积液患者462例,其中恶性胸腔积液174例、良性胸腔积液288例,收集临床相关数据并进行统计学分析。结果胸水 CEA 与血清 CEA 比值对恶性胸腔积液的诊断 ROC 曲线下面积0.918(95%CI:0.881~0.955),优于 CEA ROC 曲线下面积0.853(95%CI:0.804~0.902)。当胸水 CEA 与血清 CEA 比值最佳截断值为1.4时,诊断敏感性为0.85,特异性为0.84。结论胸水 CEA 与血清 CEA 比值对恶性胸腔积液具有良好的诊断价值,为临床诊断恶性胸腔积液提供新的依据。

[Abstract] Objective There are difficulties in making a definite diagnosis of malignant pleural effusion (MPE) and it is vital to find novel adjunctive diagnostic markers. This study intends to investigate the diagnostic value of the ratio of carcinoembryonic antigen (CEA) in pleural effusion (PE) to serum CEA in MPE. Methods A total of 462 patients with pleural effusion in Department of Respiratory and Critical Care Medicine, Nanjing Hospital Affiliated to Nanjing Medical University from January 1, 2017 to December 31, 2018 were included in this study, including 174 cases of MPE and 288 cases of benign pleural effusion. Related clinical data were collected and statistically analyzed. Results The results showed that the area under the Receiver Operating Characteristic (ROC) curve of the ratio of CEA in PE to serum CEA was 0.918(95% CI:0.881-0.955), which was better than that of CEA (0.853)(95% CI:0.804-0.902). When the best cutoff value of the ratio of CEA in PE to serum CEA was 1.4, the diagnostic sensitivity was 0.85 and the specificity was 0.84. Conclusion To sum up, the ratio of CEA in PE to serum CEA has a good diagnostic value for MPE, and provides a new basis for clinical diagnosis of MPE.

惡性胸腔积液(malignant pleural effusion,MPE)指原发于胸膜的恶性肿瘤或其他部位恶性肿瘤转移至胸膜引起的胸腔积液,生长迅速、病死率高[1-2]。MPE 确诊依赖于胸水脱落肿瘤细胞或胸膜活检阳性,但两者均存在缺陷[3-4]。目前 MPE 快速确诊存在挑战。癌胚抗原(carcinoembryonic antigen, CEA)在 MPE 形成后不易入血被清除,故 MPE CEA 较血清升高更明显[5-8]。本研究拟通过检测胸水 CEA 与血清CEA 比值,分析其诊断 MPE 敏感性、特异性,探讨胸水 CEA 与血清 CEA 比值在良恶性胸腔积液诊断中的价值。
