Abstract:
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 .
