ARTICLE HIGHLIGHTS
Research background
Successful hepatitis C virus (HCV) eradication cannot eliminate hepatocellular carcinoma (HCC) development. Chronic HCV infection induces profound alterations in cytokine and chemokine signatures. Clearance of HCV results in host immune modification, which may interfere with immune-mediated cancer surveillance.
Research motivation
The mechanism of hepatocarcinogenesis despite HCV clearance is still unclear.
Research objectives
To investigate the impact of differential cytokine expression on the development of HCC following HCV eradication.
Research methods
One hundred treatment-naïve HCV patients with advanced fibrosis who received antiviral therapy and achieved sustained virologic response (SVR) were enrolled. The primary endpoint was the development of new-onset HCC. In total, 64 serum cytokines were detected by the multiplex immunoassay at baseline and 24 wk after end-of-treatment.
Research results
The dynamics of serum tumor necrosis factor-α (TNF-α) and TNF-like weak inducer of apoptosis (TWEAK) were associated with HCC occurrence after HCV clearance. Multivariate Cox regression analysis showed that ΔTNF-α ≤ -5.7 pg/mL was an independent risk factor for HCC. An HCC predictive model comprising the Fibrosis-4 index, hemoglobin A1c, ΔTNF-α, and ΔTWEAK had excellent performance in stratifying the risk of HCC among HCV patients with SVR.
Research conclusions
Downregulation of serum TNF-α significantly increased the risk of HCC after HCV eradication.
Research perspectives
Our findings provide a clue for the pathogenesis of hepatocarcinogenesis and a strategy for HCC surveillance based on risk stratification.
