Abstract
Introduction: Simple predictive markers enabling even non-specialized medical doctors, and clinicopathological features of primary liver cancer (PLC) following HCV clearance with direct-acting antivirals (DAAs) are unclear. Methods: The subjects of this retrospective study were 2 476 patients following HCV clearance with DAAs. All patients were confirmed to be PLC-free before and during DAAs. Results: PLC was diagnosed in 73 patients during the follow-up, with an incidence rate per 1 000 person years of 5.9. The annual rate of PLC during the first 6 years was 0.6%. Multivariate analysis identified gender, GGT, and FIB-4 index as the significant determinants of PLC. According to a combination of these risk factors, the cumulative PLC incidence rates were significantly different among the five subgroups based on the number of PLC risk scores. In 73 patients with PLC, the rates of abnormal AFP, PIVKAII, and serum TERT C228T positive were 37.0, 32.4, and 22.2%. PIVKAII levels in BCLC stage A and B were significantly higher than those in stage 0. In 41 patients, who underwent surgical resection for PLC, maximum tumor diameters of abnormal PIVKAII were significantly larger than those of normal PIVKAII. PLC of abnormal PIVKAII significantly indicated presence of vp more than that of normal PIVKAII, and did not contain well-differentiated HCC. Conclusions: Combination of simple markers, enabling even non-specialized medical doctors, is useful for the evaluation of PLC risk following HCV clearance with DAAs. However, imaging studies are regularly recommended for the early detection of PLC.Keywords
