[Current Status and Future Directions of Hepatocellular Carcinoma Surveillance Test Based on Cost-effective Analysis].

Detection of hepatocellular carcinoma (HCC) at an early stage enables patients to receive curative treatment with survival gains. Current international liver society guidelines recommend the enrollment of patients at high risk for HCC in surveillance programs. In Korea, surveillance for HCC advocated for patients with chronic hepatitis B, chronic hepatitis C, and liver cirrhosis. The established surveillance tool for HCC is liver ultrasonography plus serum alpha-fetoprotein measurement every 6 months. However, there would be obstacles to the improvement of efficacy and cost-effectiveness of the HCC surveillance test. Assessing who is at risk of developing HCC remains incompletely validated. Also, which surveillance tools to use according to patients' characteristics are controversial. The present paper reviews the latest knowledge regarding the strategies and cost-effectiveness of HCC surveillance.
