目的探究血清癌胚抗原(CEA)、人附睾蛋白(HE4)、角蛋白19片段(CYFRA21-1)联合检测在肺癌患者诊断中的检测结果和应用价值。方法 37例肺癌患者作为研究组,37例健康体检者作为对照组,均采用电化学发光免疫法对患者血清CEA、HE4、CYFRA21-1水平进行检测,观察比较两组检测结果和三项指标联合检测的临床价值。结果研究组患者血清CEA、HE4、CYFRA21-1水平均高于对照组,差异具有统计学意义(P<0.05)。血清CEA、HE4、CYFRA21-1联合检测的诊断敏感性均高于CEA、HE4、CYFRA21-1各项单一检测,差异具有统计学意义(P<0.05)。结论肺癌患者采用血清CEA、HE4、CYFRA21-1等各项肿瘤标志物联合检测,可有效提高临床中肺癌诊断敏感性,检测效果良好,应用价值高。
Objective To investigate the diagnostic value and diagnostic value of combined detection of serum carcinoembryonic antigen (CEA), human epididymal protein (HE4) and keratin 19 fragment (CYFRA21-1) in patients with lung cancer. Methods Thirty-seven patients with lung cancer were selected as study group and 37 healthy individuals as control group. The levels of serum CEA, HE4 and CYFRA21-1 were detected by electrochemiluminescence immunoassay. The results of the two groups were compared with those of three indicators Detection of clinical value. Results The levels of serum CEA, HE4 and CYFRA21-1 in the study group were significantly higher than those in the control group (P <0.05). The diagnostic sensitivity of the combined detection of serum CEA, HE4 and CYFRA21-1 were higher than those of single detection of CEA, HE4 and CYFRA21-1, the difference was statistically significant (P <0.05). Conclusions The combination of serum CEA, HE4, CYFRA21-1 and other tumor markers in patients with lung cancer can effectively improve the diagnostic sensitivity of lung cancer in clinical practice. The detection effect is good and the application value is high.
