Association of central obesity with hepatocellular carcinoma in patients with chronic hepatitis B receiving antiviral therapy

Summary Background Obesity is typically associated with metabolic dysfunction, but its impact on hepatocellular carcinoma (HCC) remains unclear in patients with chronic hepatitis B (CHB). Aim To study the effect of obesity on HCC development in patients with CHB receiving antiviral therapy. Methods...

Description
Summary:Summary Background Obesity is typically associated with metabolic dysfunction, but its impact on hepatocellular carcinoma (HCC) remains unclear in patients with chronic hepatitis B (CHB). Aim To study the effect of obesity on HCC development in patients with CHB receiving antiviral therapy. Methods We included patients from a Chinese multicentre, prospective, observational, treated CHB cohort in this study. General obesity was evaluated by body‐mass index (BMI). Central obesity was evaluated by waist circumference, waist‐to‐hip ratio and waist‐to‐height ratio. Results A total of 5754 nucleos(t)ide analogue treated patients were enrolled in the analysis. The 5‐year cumulative incidence of HCC was 2.9%. Waist‐to‐height ratio performed better in predicting HCC development than BMI, waist circumference or waist‐to‐hip ratio. Patients with central obesity (defined as waist‐to‐height ratio >0.5) had significantly higher 5‐year incidence of HCC than those without central obesity in the overall population (3.9% vs 2.1%, hazard ratio [HR]: 2.06, P = 0.0001) and 745 propensity score matched pairs (4.7% vs 2.3%, HR: 2.04, P = 0.026), respectively. Besides cirrhosis status and aMAP HCC risk score, central obesity was also independently associated with HCC risk (HR: 1.63, P = 0.013). Waist‐to‐height ratio gain within 1 year was associated with a significantly higher HCC risk with an adjusted HR value of 1.88 (95% confidence interval: 1.12‐3.13, P = 0.017). Conclusions Central obesity, evaluated by the waist‐to‐height ratio, was associated with a twofold increase in HCC risk among CHB patients receiving antiviral treatment, highlighting the important role of abnormal metabolic function in the progression of liver disease.
