Abstract

Nonalcoholic fatty liver disease (NAFLD) is easily the most common cause of chronic liver disease in the United States (U.S.) as the hepatic manifestation of the metabolic syndrome. Although only 5 to 20% of patients with NAFLD are generally considered to meet criteria for nonalcoholic steatohepatitis (NASH), with its inherent risk for progression to cirrhosis, this still represents an alarmingly large number of individuals. The exponentially growing rates of hepatocellular carcinoma (HCC) in the U.S. may be partially attributable to increased numbers of NASH cirrhotics, although recent evidence has suggested that NAFLD may directly promote hepatic carcinogenesis independent of cirrhosis. This review focuses on HCC in noncirrhotic NASH with an emphasis on clinical presentation, pathogenesis, and implications for screening.
