目的:通过检测肿瘤型 M2丙酮酸激酶(TuM2-PK )、细胞角蛋白18(CK18)-3A9和细胞角蛋白19片段(CYFRA21-1)在非小细胞肺癌(NSCLC)患者血清中的表达水平,评价其在NSCLC中的诊断价值。方法收集67例NSCLC患者(NSCLC组),72例肺部良性疾病患者(良性组)和75健康体检者(对照组)的血清,采用酶联免疫吸附试验(ELISA )检测TuM2-PK和CK18-3A9水平,采用电化学发光法检测CYFRA21-1水平。结果与对照组及良性组比较,NSCLC组 TuM2-PK、CK18-3A9和CYFRA21-1水平明显升高(P<0.05)。单一指标检测时,TuM2-PK、CK18-3A9的敏感性明显高于CYFRA21-1(P<0.05),CYFRA21-1的特异性明显高于TuM2-PK、CK18-3A9(P<0.01)。3项指标联合检测,其敏感性和准确性均高于单独检测CYFRA21-1(P<0.05);3项指标联合检测,其敏感性、特异性和准确性均高于单独检测TuM2-PK和CK18-3A9(P<0.05)。结论 TuM2-PK、CK18-3A9和CYFRA21-1联合检测可有效提高NSCLC诊断的敏感性和准确性。
目的:通過檢測腫瘤型 M2丙酮痠激酶(TuM2-PK )、細胞角蛋白18(CK18)-3A9和細胞角蛋白19片段(CYFRA21-1)在非小細胞肺癌(NSCLC)患者血清中的錶達水平,評價其在NSCLC中的診斷價值。方法收集67例NSCLC患者(NSCLC組),72例肺部良性疾病患者(良性組)和75健康體檢者(對照組)的血清,採用酶聯免疫吸附試驗(ELISA )檢測TuM2-PK和CK18-3A9水平,採用電化學髮光法檢測CYFRA21-1水平。結果與對照組及良性組比較,NSCLC組 TuM2-PK、CK18-3A9和CYFRA21-1水平明顯升高(P<0.05)。單一指標檢測時,TuM2-PK、CK18-3A9的敏感性明顯高于CYFRA21-1(P<0.05),CYFRA21-1的特異性明顯高于TuM2-PK、CK18-3A9(P<0.01)。3項指標聯閤檢測,其敏感性和準確性均高于單獨檢測CYFRA21-1(P<0.05);3項指標聯閤檢測,其敏感性、特異性和準確性均高于單獨檢測TuM2-PK和CK18-3A9(P<0.05)。結論 TuM2-PK、CK18-3A9和CYFRA21-1聯閤檢測可有效提高NSCLC診斷的敏感性和準確性。

Objective To investigate the value of tumor M2 pyruvate kinase (TuM2-PK ) ,cytokeratin-18 (CK18 )-3A9 and cytokeratin 19 fragment(CYFRA21-1) in non small cell lung cancer(NSCLC) ,and to evaluate the application value of combined de-tection of these three kinds tumor markers in diagnosis of NSCLC .Methods The serum levels of TuM2-PK and CK18-3A9 were measured in 67 patients with NSCLC(NSCLC group) ,72 patients with benign lung diseases(benign group) and 75 healthy control (control group) by enzyme linked immunosorbent assay(ELISA) .The level of CYFRA21-1 was detected by electrochemilumines-cence method .Results The serum levels of TuM2-PK ,CK18-3A9 and CYFRA21-1 in NSCLC group were higher than those in be-nign group and control group(P<0 .05) .The sensitivity of TuM2-PK or CK18-3A9 was better than CYFRA21-1(P<0 .05) ,the specificity of CYFRA21-1 was better than TuM2-PK or CK18-3A9(P<0 .01) .The sensitivity and accuracy of combined detection of TuM2-PK ,CK18-3A9 and CYFRA21-1 were both better than CYFRA21-1(P<0 .05) .The sensitivity ,specificity and accuracy of combined detection of TuM2-PK ,CK18-3A9 and CYFRA21-1 were all better than TuM2-PK or CK18-3A9 alone(P<0 .05) .Con-clusion The combined detection of TuM2-PK ,CK18-3A9 and CYFRA21-1 were better in sensitivity and accuracy of diagnosis of NSCLC .
