Method: A retrospective study was conducted on 182 patients with hepatitis B virus (HBV) infection in our hospital’s outpatient and inpatient departments. The liver cancer group was divided into AFP positive and AFP negative subgroups, and the receiver operating characteristic (ROC) curve was used to evaluate the diagnostic efficacy of different tumor markers for PLC. Results: Serum ALT, AST, ALP, ALB, PLT, PT and INR levels were significantly different among the three groups (P P > 0.05). The serum levels of AFP, AFP-L3, and AFP-L3% were higher in the AFP positive subgroup, and the differences were statistically significant (P P > 0.05). The difference in GP73 levels between the AFP positive and AFP negative subgroups and the non liver cancer group was not significant (P > 0.05). In the AFP positive subgroup, besides AFP, AFP-L3 showed the highest sensitivity (97.30%) and specificity (84.50%), while in the AFP negative subgroup, AFP-L3% showed the highest specificity. Conclusion: The diagnostic value of serum AFP-L3 and AFP-L3% levels for primary liver cancer is higher in the AFP positive subgroup, while the diagnostic value of serum GP73 level for PLC is lower.展开更多
