Hepatocellular carcinoma is a leading cause of death worldwide, and cirrhosis is the main risk factor
Infection with hepatitis B and hepatitis C is the main cause of underlying liver disease
Prevention of chronic liver disease would greatly reduce incidence
Early tumour diagnosis through screening of at risk groups is cost effective
New treatments, such as sorafenib, are exciting potential adjuncts to patient care
Hepatocellular carcinoma is the third most common cause of cancer related mortality worldwide, and in the United Kingdom population data show that age standardised incidence rose from 1.4 to 3.9 per 100 000 people between 1975 and 2006 (http://info.cancerresearchuk.org/cancerstats/types/liver). Cirrhosis of the liver is the strongest predisposing factor—80-90% of cases arise from chronic liver disease. Furthermore, in cohort studies of patients with cirrhosis, hepatocellular carcinoma is the leading cause of liver related death.1 2

We based this review on the available evidence presented in international consensus guidelines and cited in PubMed after searching with the terms “hepatocellular carcinoma”, “natural history”, “surveillance”, “screening”, “outcome”, “treatment”, and “prevention”.
What predisposes people to hepatocellular carcinoma?
Worldwide rates of hepatocellular carcinoma (fig 1⇓) correlate with widespread infection with hepatitis B in Asia and Africa and hepatitis C in Western countries and Japan. These viral infections are the most common underlying causes of liver disease that predispose to hepatocellular carcinoma (box 1).
Box 1 Important risk factors for hepatocellular carcinoma
Cirrhosis (any cause)
Chronic hepatitis B and C infection
Sustained added excess alcohol consumption
Non-alcoholic steatohepatitis (both independently and as a cofactor)
Family history of hepatocellular carcinoma
