We examined the immunohistochemical expression of IFNalpha/betaR in 91 hepatocellular carcinoma (HCC), HCV-related chronic hepatitis (n=38) and cirrhosis (n=53), dysplastic nodules (n=5), and normal liver (n=9). The level of IFNalpha/betaR increased in chronic hepatitis and cirrhosis compared with normal liver. All the dysplastic nodules showed moderate or high expression. In HCCs, 26% (24/91) of patients showed high IFNalpha/betaR expression while the remaining 38% (35/91) showed moderate, and 35% (32/91) no or faint expression. Clinicopathological survey demonstrated a significant correlation between IFNalpha/betaR expression and differentiation of carcinoma (P=0.0008) although there was no correlation between IFNalpha/betaR expression in HCC and survival or disease-free survival. Thus, IFNalpha/betaR was expressed not only in chronic hepatitis or liver cirrhosis but in HCC and its expression was significantly correlated with tissue differentiation of carcinoma.PMID: 10853022, UI: 20313011 >>
