Abdominal ultrasound, with or without alpha-fetoprotein, is the recommended strategy for hepatocellular carcinoma (HCC) surveillance but misses over one-third of HCC at an early stage. Emerging imaging modalities, including computed tomography and magnetic resonance imaging, have early data showing high sensitivity for early-stage HCC, but potential issues such as radiologic capacity, patient acceptance, cost-effectiveness, and need for validation in Western non-hepatitis B virus populations still need to be evaluated. Similarly, blood-based biomarker panels, including GALAD and liquid biopsy techniques, have shown promising data in phase II case-control studies and may concurrently help address issues of surveillance underuse; however, these tools require validation in phase III and IV cohort studies. While awaiting prospective validation data for these emerging strategies, ultrasound with or without alpha-fetoprotein remains the current gold standard HCC surveillance strategy.
