Abstract:
Objective To evaluate the application value of serum tumor markers in small cell lung Cancer, and analyse the relationship between serum tumor markers and immunohistochemistry indicators.Methods The electrochemical luminescence technology was used to detect the concentration of carcino-embryonic anti-gen(CEA),neuronspecific enolase(NSE),cyto-keratin fragment 19(CYFRA21-1),the immunological lumines-cence technology was used to detect the concentration of ProGRP,the expression of Ki-67,TTF-1 were detec-ted by MaxVision immunohistochemistry methods,the date was analyzed by two independent sample rank sum test,rank correlation methods,chi-square test and ROC curve.Results The concentration of CEA,NSE,pro-gastrin-releasing peptide(ProGRP),CYFRA21-1 in SCLC were higher than that in benign disease,the concen-tration of CEA,NSE,ProGRP,CYFRA21-1 in extensive stage were higher than that in limited stage(P<0. 05),the difference was statistically significant.The ROC area of NSE,ProGRP were large,they were 0.972 and 0.965,the Kappa value of the NSE+ProGRP was 0.860,optimstic data consistency with "the gold stand-ard".There was a negative relationship between Ki-67 and CEA,NSE,ProGRP,the positive rate of TTF-1 was higher than CYFRA21-1,while lower than ProGRP,But NSE,CEA and TTF-1 have same results(P>0.05). Conclusion Combined detection NSE and ProGRP is of great value in the diagnosis and periods of SCLC,the sensibility and specificity of NSE+ProGRP was high in SCLC,he high expression of Ki-67 was not responsed the concentration of serum tumor markers,TTF-1 had the same results with NSE,while inferior to ProGRP in detect of SCLC.
