摘要
目的 探讨血清穿透素-3(serum penetrates-3,PTX-3)、细胞角蛋白片段(cytokeratin fragment 1,CYFRA21-1)和组织多肽特异性抗原(tissue polypeptide specific antigen,TPS)在非小细胞肺癌(non-small cell lung cancer,NSCLC)中的变化及其临床应用价值.方法 2013年10月~2014年10月选取58例NSCLC患者,60例肺部良性疾病组及60例健康对照者,采用ELISA法测定三组血清PTX-3,CYFRA21-1和TPS水平,采用受试者特异曲线(ROC)评价血清PTX-3,CY-FRA21-1和TPS在早期NSCLC患者中的应用价值.结果 NSCLC组血清PTX-3,CYFRA21-1和TPS水平分别为9.86±2.56 g/L,4.98±0.85 g/L和181.25±45.36 U/L,显著高于肺部良性疾病组的3.36±1.45 g/L,1.21±0.45 g/L,84.25±8.45 U/L和健康对照组2.18±0.78 g/L,1.12±0.25 g/L,62.32±5.96 U/L,差异有统计学意义(F=9.863,5.778,15.963,均P<0.05).NSCLC组患者中疾病进展(disease progression,PD)患者血清PTX 3,CYFRA21-1和TPS水平显著高于疾病稳定(stable disease,SD),部分缓解(partial remission,PR),完全缓解(complete remission,CR)者,两两比较差异有统计学意义(F=23,7.123,21.236,均P<0.05).经ROC分析可知,PTX-3,CYFRA21-1和TPS联合诊断时敏感度、特异度最高.结论 血清PTX-3,CYFRA21 1,TPS水平在NSCLC早期诊断及预后评估中具有一定的应用价值,三者联合诊断可提高诊断准确率,可作为NSCLC早期辅助诊断及预后判断的标志物.
Objective To investigate the changes and clinical significance of serum pentraxin -3 (PTX-3), cytokeratin frag- ment 19 (CYFRA21-1) and polypeptide specific antigen (TPS) in non-small cell lung cancer (NSCLC). Methods The lev- els of PTX-3,CYFRA2]-] and TPS of 58 cases of NSCLC patients,60 cases of benign lung disease group and 60 healthy control subjects were determined by ELISA from october 2013 to october 2014. The value of PTX-3 ,CYFRA21-I and TPS of NSCLC were evaluated with subjects specific curve (ROC). Results The levels of PTX-3 (9.86±2.56 g/L) ,CYFRA21- 1 (4.98±0.85 g/L) ,TPS (181.25±45.36 U/L) of NSCLC were higher than those in lung disease group (3.36±1. 45 g/ L,1. 21±0. 45 g/L,84.25±8.45 U/L) and the healthy control group (2.18±0.78 g/L,1.12±0.25 g/L,62.32±5.96 U/ L) (F= 9. 863,5. 778,15. 963, all P〈0.05). The levels of PTX-3, CYFRA2]-], TPS of PD NSCLC patients were higher than stable disease (SD),partial response (PR) and complete remission (CR) (F=8. 123,7. 123,21. 236,P〈0.05). The ensitivity and accuracy of PTX-3 jiont CYFRA21 1,TPS were higher than sigle Index by ROC analysis. Conclusion Serum PTX 3, CYFRA21-1, TPS has a certain level of value in the early diagnosis and prognosis of NSCLC, the combination of the three can improve the diagnostic accuracy of diagnosis can be used as an early NSCLC diagnosis and prognosis markers.
