摘要

•Whether HBsAg seroclearance affects the risk of late (≥2 years) HCC recurrence after liver resection remains unanswered. •2,520 consecutive Korean patients who underwent curative-intent liver resection for HBV-related HCC of BCLC 0 or A were analyzed. •HBsAg seroclearance after liver resection was independently associated with a reduced risk of late (≥2 years) HCC recurrence. Background & Aims It is unknown whether HBsAg seroclearance affects the risk of hepatocellular carcinoma (HCC) recurrence after liver resection. We aimed to investigate the impact of HBsAg seroclearance on the recurrence of HCC after curative liver resection, with a focus on late recurrence. Methods This study comprised 2,520 consecutive patients who received curative liver resection for HBV-related HCC of Barcelona Clinic Liver Cancer stage 0 or A in Korea between 2000 and 2017. To focus on late recurrence, patients with recurrence or a follow-up duration less than 2 years were excluded. The impact of HBsAg seroclearance on HCC recurrence was assessed by landmark analysis (2-, 5-and 8-year after liver resection), time-dependent Cox and multistate modeling. Results The mean patient age was 54.4 years and 75.7% were men. A total of 891 (35.4%) patients developed HCC recurrence at rates of 11.2%, 25.5%, and 46.8% at 3, 5, and 10 years after resection. HBsAg seroclearance was achieved in 172 (6.8%) patients during a median follow-up duration of 6.9 years after resection. HBsAg seroclearance, compared with persistent HBsAg positivity, was associated with a lower risk of late HCC recurrence in the 2-, 5-, and 8-year landmark analysis (p = 0.04, p = 0.02 and p = 0.03, respectively) and on time-dependent multivariable Cox modeling (adjusted hazard ratio 0.62; p = 0.005). Based on a 3-state unidirectional illness–death model, patients without HBsAg seroclearance transitioned to HCC recurrence more rapidly than patients who experienced HBsAg seroclearance. Conclusions HBsAg seroclearance is associated with a lower risk of late recurrence of HBV-related HCC among Korean patients who undergo curative liver resection. Lay summary Hepatitis B virus (HBV) infection is a leading cause of chronic liver disease and hepatocellular carcinoma (HCC). Suppression of HBV replication is known to lower the risk of HCC recurrence after liver resection (a procedure used to treat and in some cases cure HCC). However, whether the loss of a specific HBV protein (hepatitis B surface antigen or HBsAg) has an impact on recurrence after liver resection remains unknown. Herein, we show that loss of HBsAg is associated with a reduce risk of late recurrence of HCC after liver resection in patients with HBV-related HCC. It is unknown whether HBsAg seroclearance affects the risk of hepatocellular carcinoma (HCC) recurrence after liver resection.
