Aim: Serum glycosylated Wisteria floribunda agglutinin-positive Mac-2 binding protein (WFA+ -M2BP) is a reliable, non-invasive marker of liver fibrosis. This study assessed the ability of WFA+ -M2BP to diagnose liver fibrosis in patients with chronic hepatitis B virus (HBV) infection and evaluated WFA+ -M2BP as a predictor of hepatocellular carcinoma (HCC) development.
Methods: Serum WFA+ -M2BP values were retrospectively evaluated in 112 treatment-naïve patients with HBV-related chronic hepatitis and cirrhosis who had undergone liver biopsy at our hospital.
Results: Serum WFA+ -M2BP levels were significantly related with liver fibrosis (r = 0.3725, P = 0.001). Fibrosis stage F2, F3, and F4 had a cut-off index of 0.94, 1.26, and 1.26, respectively. For diagnosing F ≥ 2 fibrosis, the area under the receiver-operating characteristic curve for WFA+ -M2BP was 0.713 and comparable with those of other non-invasive fibrosis markers, such as hyaluronic acid, type IV collagen 7S, aspartate aminotransferase-to-platelet ratio index, fibrosis-4 index, serum albumin, and platelet count. Multivariate analysis identified male, WFA+ -M2BP ≥0.71, alanine aminotransferase ≥80 IU/L, and platelet count <14.5 × 109 /L as independent risk factors for the development of HCC in patients with HBV infection.
Conclusions: Serum WFA+ -M2BP values appear to be useful for assessing liver fibrosis stage and are independently associated with HCC development in patients with chronic HBV infection.
