Diagnostic value of combined serum AFP,TK1 and DKK1 levels in primary liver cancer / 国际检验医学杂志

ABSTRACT

Objective To investigate the diagnostic value of combined detection of serum alpha fetoprotein (AFP),thymidine kinase 1(TK1)and secreted protein Dickkopf-1(DKK1)in patients with primary liver cancer(PHC).Methods 85 patients with PHC admitted to the hospital from August 2015 to October 2016 were selected as PHC group,and 73 patients with benign liver disease as benign liver disease group,and 80 ca-ses healthy subjects as the control group.The serum levels of AFP,TK1 and DKK1 were detected in three groups,and the differences in each group were compored,and the diagnostic sensitivity,specificity,positive predictive value,negative predictive value and accuracy were calcuated.The diagnostic value of each index was analyzed by logistic regression.Results The serum AFP,TK1 and DKK1 levels in PHC group were signifi-cantly higher than those in benign liver disease group and control group(P<0.05),the serum AFP TK1 and DKK1 levles in benign liver disease group were significantly higher than those in the control group(P<0.05);the sensitivity,accuracy and negative predictive value of AFP + TK1+ DKK1 joint detection were sig-nificantly higher than that in the single index detection(P<0.05);Logistic regression analysis showed that AFP,TK1 and DKK1 were closely correlated with the diagnosis of PHC(P<0.05).Conclusion The com-bined detection of serum AFP,TK1 and DKK1 can significantly improve PHC positive diagnosis rate,which is of great significance for clinical early diagnosis and effective treatment,and is worth popularizing.
