Abstract
Background: Hepatitis Cvirus (HCV)-infected patientswho achieve viral eradicationmay still develop hepatocellular carcinoma (HCC). Little is known about the impact of dynamic change of serum markers on HCC development. Methods: We enrolled 1351 HCV-infected patients who achieved sustained virological response (SVR). Laboratory datawere collected at least 1 year after IFN-based therapy and to the latest follow-up. Data on α-fetoprotein (AFP) were obtained >6 months prior to HCC development to exclude HCC-related AFP elevation. Results: HCC developed in 49 patients. Risk factors for HCC in SVR patients were old age, liver cirrhosis, higher pre- and post-treatment AFP and high post-treatment AST-to-platelet ratio index (APRI). Patients with pre- AFP ≥15 ng/mL→post-AFP ≥15 ng/mL (at 1 year, 23.1%; 5 years, 42.3%) and pre-AFP <15 ng/mL→post-AFP ≥15 ng/mL (at 1 year, 25%; 5 years, 50%) had the highest risk of HCC development, followed by pre- AFP ≥15 ng/mL→post-AFP<15 ng/mL (at 1 year, 5.2%; 5 years, 7.6%) and pre-AFP<15 ng/mL→post-AFP ng/mL <15 ng/mL (at 1 year, 0.5%; 5 years, 0.9%) (P<0.001). The pattern was similar for platelets and APRI (P<0.001). SVR patients with pre-APRI ≥0.7→post-APRI ≥0.7 had the highest risk of HCC development, followed by comparable risks among the other three groups. Conclusions: SVR patients with a persistently high AFP level (≥15 ng/mL) and a high APRI (≥0.7) before and after treatment had the highest incidence of HCC development. Patients with a reduction of AFP and APRI to the normal range after treatment had a markedly decreased risk of HCC. The risk was lowest for patients who kept persistently normal AFP and APRI before and after treatment.
