Hepatocellular carcinoma surveillance in Australia: current and future perspectives

Hepatocellular carcinoma (HCC) is a leading cause of cancer-related death worldwide, and is increasing in incidence in Australia.For most people with cirrhosis and chronic hepatitis B, HCC screening and surveillance is recommended with 6-monthly ultrasound. However, most patients with HCC are still diagnosed outside of surveillance with incurable disease.While HCC surveillance almost certainly reduces cancer-related mortality, the potential harms of surveillance are incompletely understood.Surveillance uptake remains suboptimal in many contexts, and stems from a combination of patient, clinician and system level barriers.Improved case-finding strategies may be required to identify high risk individuals in need of surveillance, as cirrhosis and viral hepatitis are often asymptomatic.HCC prediction models and novel surveillance tools such as biomarker panels, computed tomography and magnetic resonance imaging may have a future role in personalised HCC surveillance.Analyses suggest surveillance may be cost-effective, but Australian data remain limited.A centralised HCC surveillance program may ultimately have a role in delivering improved and more equitable care.
