Assessment of the correlation between serum prolidase and alpha-fetoprotein levels in patients with hepatocellular carcinoma

Figure 1 Relationship between serum prolidase and alpha fetoprotein levels in patients with hepatocellular carcinoma (r = 0. 616; P < 0.01).

Figure 2 Relationship between serum prolidase and alpha fetoprotein levels in patients with hepatocellular carcinoma with regard to tumor size (A), number (B), barcelona-clinic liver cancer staging (C) and macrovascular invasion (D).

Figure 3 Receiver operating characteristic curves of prolidase and alpha fetoprotein levels. A: Predictive value of prolidase and α-fetoprotein (AFP) regarding tumor size (diameters; ≤ 3 cm and > 3 cm ); B: Predictive value of prolidase and AFP regarding tumor number (number; ≤ 1 and ≥ 2 ).
