Dickkopf-1: as a diagnostic and prognostic serum marker for early hepatocellular carcinoma.

Background And Aims: The aim of the present study was to evaluate serum Dickkopf-1 (Dkk-1) as a marker for early detection of hepatocellular carcinoma (HCC), as well as for prognostic prediction of early HCC after hepatic resection.

Methods: One-hundred and four cases of matched fresh tissue specimens of early HCC and adjacent non-tumorous liver tissue (ANLT) were obtained for RT-PCR, qRT-PCR, western blot and immunohistochemistry assays. Sera were collected from patients with early HCC (n=184), benign liver tumors (n=29), cirrhosis (n=174), non-cirrhotic hepatitis B (n=193), and from healthy individuals (n=202).

Current therapy of hilar cholangiocarcinoma.

Background: Hilar cholangiocarcinoma (HC) is an adenocarcinoma of the extrahepatic biliary tree arising from the main left or right hepatic ducts or their confluence. This tumor is still considered to be difficult to treat or to cure.

Data Sources: We reviewed the medical literature on HC.
