Evaluation of high-risk factors and the diagnostic value of alpha-fetoprotein in the stratification of primary liver cancer

Figure 2 Area under the curve. A-B: Represent small tumors and primary liver cancer (PLC) at Barcelona Clinic Liver Cancer (BCLC) stage A, respectively. Data above demonstrated that alpha-fetoprotein (AFP) had little diagnostic value in PLC patients with small tumors and at BCLC stage A. As shown, carcinoembryonic antigen, carbohydrate antigen 19-9, and gamma-glutamyl transferase improved the diagnostic value of AFP. AFP: Alpha-fetoprotein; BCLC: Barcelona Clinic Liver Cancer; CEA: Carcinoembryonic antigen; CA 19-9: Carbohydrate antigen 19-9; GGT: Gamma-glutamyl transferase.
