Are patients with cirrhotic stage primary sclerosing cholangitis at risk for the development of hepatocellular cancer?
OBJECTIVE
The risk of cholangiocarcinoma in primary sclerosing cholangitis is widely recognized to be 8-30%, whereas the risk of acquiring hepatocellular carcinoma in primary sclerosing cholangitis is unknown. As in other chronic liver diseases, the presence of hepatocellular carcinoma in a patient with primary sclerosing cholangitis undergoing evaluation for orthotopic liver transplantation would clearly impact on the candidacy, diagnostic evaluation, and alternative treatment options. Thus, the aim of our study was to determine the prevalence of hepatocellular carcinoma in patients undergoing liver transplantation for primary sclerosing cholangitis.


METHODS
The records of the 520 patients undergoing orthotopic liver transplantation at our institution between 1985 and May 1995 were reviewed. Of the 134 patients with primary sclerosing cholangitis, three (2%) had hepatocellular carcinoma. In the 386 patients without primary sclerosing cholangitis undergoing orthotopic liver transplantation, 22 (6%) had hepatocellular carcinoma.


RESULTS
Neither the duration of primary sclerosing cholangitis (range 7-23 years) nor the presence of ulcerative colitis (two of three patients) distinguished those patients with primary sclerosing cholangitis plus hepatocellular carcinoma from those with primary sclerosing cholangitis alone. None of the three patients with primary sclerosing cholangitis plus hepatocellular carcinoma had evidence for hepatitis B or C, alpha-1-antitrypsin deficiency, or hemochromatosis. None of the tumors was of the fibrolamellar variety of hepatocellular carcinoma.


CONCLUSIONS
The prevalence of hepatocellular carcinoma in patients with primary sclerosing cholangitis undergoing orthotopic liver transplantation is 2%. These data suggest that patients with advanced cirrhotic-stage primary sclerosing cholangitis are at increased risk for developing hepatocellular carcinoma and should be screened for hepatocellular carcinoma as well as for cholangiocarcinoma prior to orthotopic liver transplantation.
