摘要
目的:探讨人端粒酶逆转录酶(human telomerase reverse transcriptase,hTERT)、CEA、CA19-9在鉴别诊断良恶性胸腔积液的意义。方法:采用全自动化学发光法检测胸腔积液中CEA、CA19-9含量及RT-PCR检测胸腔积液中hTERT mRNA表达。结果:恶性组中hTERTmRNA、CEA、CA19-9阳性率显著高于良性组(P<0.05)。三者在恶性胸腔积液的敏感性(%)、特异性(%)和诊断符合率(%)分别为:hTERT mRNA:81.8/90.5/86.1,CEA:52.3/92.9/72.1,CA19-9:34.1/90.5/61.6。hTERT mRNA+CEA在恶性胸腔积液中诊断阳性率97.7%。结论:三者均有助于良恶性胸腔积液的鉴别诊断,而hTERT mRNA对于鉴别良恶性胸腔积液有更大的临床价值,CA19-9不宜作为首选指标;hTERT mRNA和CEA联合检测可以进一步提高恶性胸腔积液的阳性检出率,有助于提高其诊断价值。
Objective: To.detect hTERT mRNA, CEA, and CA19-9 in pleural fluids and to explore their significance in the differential diagnosis of malignant and-benign effusions. Methods: The concentrations of CEA and CA19-9 in pleural fluids were measured by automated chemiluminescence and the expression of hTERT mRNA was detected by RT-PCR. Results: The positive rates of hTERT mRNA, CEA and CA19-9 were significantly higher in the malignant group than in the henigh group (P〈0.05). The sensitivity, specificity and diagnostic accordance Late. (%) of the three tumor markers were as follows: hTERT mRNA: 81.8%, 90.5%, and 86.1%; CEA: 52.3%, 92.9%, and 72.1%; CA19-9: 34.1%, 90.5%, and 61.6%. The positive rate of hTERT mRNA combined with CEA was 97.7%. Conclusion: Detection of hTERT mRNA, CEA, and CA19-9 can be helpful for the differential diagnosis of pleural effusions. The combined detection of hTERT mRNA and CEA in pleural effusions is a more helpful method.
