| Abstract: | European and American guidelines recommend surveillance for hepatocellular carcinoma (HCC) by performing ultrasonography on a six-month basis on an at risk population, defined by presence of cirrhosis. HCC, due to non-alcoholic steatohepatitis (NASH), is rising. Patients with NASH have a high risk of developing HCC and, therefore, have to be enrolled in a screening program. One of the challenges with NASH-induced HCC is that half of the cases arise in non-cirrhotic patients. There is a need to identify those patients in order to screen them for HCC. The obesity of these patients is another challenge, it makes ultrasound screening more difficult. Other radiological methods, such as computer tomography (CT) scans or magnetic resonance imaging (MRI), are available, but the surveillance program would no longer be cost-effective. There is a need to prospectively acquire information on cohorts of patients with NASH in order to improve the tools we have to diagnose early tumors in these patients. |
