[Expression of epidermal growth factor receptor, ErbB2 and matrix metalloproteinase-9 in hepatolithiasis and cholangiocarcinoma].

Abstract

EGFR expression appears to be the dominant component in periductular hyperplasia of hepatolithiasis and MMP-9 is upregulated not only in cholangiocarcinoma but also in hepatolithiasis. This study suggests that EGFR and MMP-9 are associated with cholangiocarcinoma and hepatolithiasis.
