ABSTRACT
Although the overall prognosis of patients with HCC is still poor, patients diagnosed at early stage through surveillance can be expected to have an improved survival with curative treatments. Accordingly, ultrasound-based hepatocellular carcinoma (HCC) surveillance programs proposed by international society guidelines are now being implemented and updated continuously based on the latest evidence to improve their efficacy. Recently, other imaging modalities such as magnetic resonance imaging have shown potentials as an alternative surveillance tool based on individualized risk stratification. In this review article, we describe the current status of ultrasound-based surveillance for HCC with the supporting evidence. We also discuss alternative surveillance imaging modalities that are underway to validate their diagnostic performance and cost-effectiveness.
