Serum Mac‐2‐binding protein glycosylation isomer and risk of hepatocellular carcinoma in entecavir‐treated chronic hepatitis B patients

Abstract Background To investigate serum Mac-2-binding protein glycosylation isomer (M2BPGi) levels in predicting hepatocellular carcinoma (HCC) and mortality at virological remission (VR, HBV DNA <20 IU/mL) following antiviral therapy in chronic hepatitis B (CHB) patients with cirrhosis. Methods This retrospective cohort study included patients with CHB-related Child-Pugh A cirrhosis undergoing long-term antiviral therapy. Serum M2BPGi levels were quantified and multivariable Cox proportional hazards regression models were used to identify risk predictors for HCC and death. Results A total of 126 and 145 patients were included in the derivation and validation cohorts, respectively. The mean age was 56, and the mean M2BPGi level was 1.86 cut-off index (COI) in the derivation cohort. After adjustment for confounders, a higher M2BPGi level at VR significantly predicted HCC (hazard ratio [HR]: 1.58, 95% confidence interval [CI]: 1.19-2.10, P=0.002) and death (HR: 2.17, 95% CI: 1.02-4.62, P=0.044). The M2BPGi ³3 COI significantly increased the risk of HCC and death in the derivation and validation cohorts. Serial M2BPGi levels declined significantly (P=0.0001) in non-HCC patients only, and remained significantly lower than those who developed HCC afterwards (P=0.039). Conclusions Serum M2BPGi levels at antiviral therapy-induced VR predict HCC development and death in patients with CHB-related Child-Pugh A cirrhosis.

Fibrosis Marker

We aimed to analyze the serum level of a novel fibrosis marker, Mac-2-binding protein glycosylation isomer (M2BPGi), and its predictive value for hepatocellular carcinoma (HCC) development in chronic hepatitis B (CHB) under nucleot(s)ide analogue (NA) therapy. Serum M2BPGi levels were quantified in 147 CHB patients at baseline, 48 weeks after starting NA therapy, and at the patients’ last visit. The serum M2BPGi level serially decreased at each time point. During the median follow-up time of 6.6 years, 14 of 147 patients developed HCC. Multivariate Cox proportional hazard analysis demonstrated that high serum M2BPGi at 48 weeks was an independent risk factor for HCC development. A cutoff value of M2BPGi at 48 weeks > 1.5 showed an adjusted hazard ratio = 34.9 (95% confidence interval, 4.3–284.9). The 3- and 5-year cumulative incidence of HCC in patients with low M2BPGi were 0.9% and 4.2%, respectively, whereas those in patients with high M2BPGi were 10.1% and 25.6%, respectively (p < 0.001). In conclusion, Serum M2BPGi level at 48 weeks is a useful predictor for HCC development in patients with CHB who receive NA therapy.
