We aimed to evaluate PIVKA-II in comparison to established pancreatic cancer (PC) biomarkers (CA 19-9, carcinoembryonic antigen (CEA) and CA 242) measured in PC patients and in patients with benign pancreatic diseases. Materials and methods: We studied 26 PC patients (Group 1) and 20 patients with benign pancreatic diseases (Group 2). PIVKA-II and CEA were measured by chemiluminescent enzyme immunoassay method (CLEIA) on LUMIPULSE G1200 (Fujirebio-Europe, Gent, Belgium), CA 19-9 and CA 242 were measured by ELSA (CisBio Bioassays, Codolet, France) and EIA (Fujirebio Diagnostics AB, Gˋteborg, Sweden), respectively. Receiver operating characteristic (ROC) analysis was performed to assess biomarkers* diagnostic characteristics in both groups. Results: Median and interquartile range (IQR) in Group 1 and Group 2 were: 1749.0 (320.2 每 3921.0) vs. 31.0 (23.0 每 43.0) mAU/mL (P < 0.001) for PIVKA-II, 260.0 (158.7 每 272.0) vs. 45.2 (9.0 每 58.0) U/mL (P = 0.034) for CA 19-9, 104.0 (30.2 每 150.0) vs. 7.2 (4.8 每 26.0) U/mL (P < 0.050) for CA 242, 9.4 (5.3 每 37.5) vs. 4.5 (1.8 每 7.0) ng/mL (P = 0.021) for CEA. Areas under the ROC curve of PIVKA-II, CA 19-9, CA 242, CEA were 0.86 (95% CI: 0.71 每 1.00), 0.58 (95% CI: 0.38 每 0.78), 0.73 (95% CI: 0.54 每 0.92), 0.64 (95% CI: 0.44 每 0.85), respectively. Conclusions: PIVKA-II is significantly higher in PC than in benign pancreatic diseases. PIVKA-II shows a rather good diagnostic performance compared to CA 19-9, CEA and CA242, thus its determination could help PC management %K pancreatic cancer %K PIVKA-II %K CA 19-9 %K CA 242 %K CEA %U https://hrcak.srce.hr/index.php?show=clanak&id_clanak_jezik=322742
