BACKGROUND Diagnostic accuracy of various tumor markers and their combinations for hepatocellular carcinoma(HCC)was not fully *** To evaluate the diagnostic accuracy of alpha-fetoprotein(AFP),the Lens culinaris agglutinin-reactive fraction of AFP(AFP-L3),and protein induced by vitamin K absence or antagonist-II(PIVKA-II)and their combination for HCC *** Patients with newly detected liver mass or elevated serum AFP levels were considered *** AFP level,AFP-L3 fraction,and PIVKA-II level were measured at the first *** In total,622 patients were included;355 patients(57.1%)had chronic liver disease,and 208(33.4%)had liver *** was diagnosed in 160 patients(25.7%).The area under the receiver operating characteristics curves(AUROCs)of the serum AFP,AFP-L3 fraction,AFP-L3,and PIVKA-II levels for the diagnosis of HCC were 0.775,0.792,0.814,and 0.834,respectively.A novel diagnostic model was developed by classifying patients in a 1:1 ratio into training and validation *** the binary regression analysis of the training cohort,the AFP,AFP-L3 fraction,and PIVKA-II(ALPs)score was calculated as follows:ALPs score=3.8×[serum AFP level(ng/mL)×AFP-L3 fraction(%)×0.01]+0.2×PIVKA-II level(mAU/mL).The AUROC of the ALPs score for diagnosis of HCC was 0.878,significantly higher than that of serum AFP level(P<0.001),AFP-L3 fraction(P<0.001),PIVKA-II level(P=0.036),and AFP-L3 level(P=0.006).The optimal ALPs score cut-off was 5.3(sensitivity,85.0%,specificity 80.1%).The validation cohort showed similar *** The ALPs score calculated using serum AFP level,AFP-L3 fraction,and PIVKA-II level showed improved accuracy in HCC diagnosis.
