Background: The Korean National Cancer Screening Programme (NCSP) for liver cancer was initiatedin 2003. The objective of this study was to evaluate participation in the NCSP and provide essential evidenceassociated with the screening of Korean adults at high risk for liver cancer.
Methods: Liver cancer screeningwas conducted in two stages. During the first, the fraction of the population at high risk for liver cancer wasidentified through detection of the hepatitis B virus surface antigen (HBsAg) and hepatitis C virus antibodies(anti-HCV Ab). During the second stage, this high-risk population was kept under surveillance to detect livercancers as quickly as possible, and screening participation rates and recall rates were assessed. We estimated the95% confidence intervals (CIs) for all outcome measures.
Results: In the first stage, 2.57% (95% CI, 2.47-2.67)of Medical Aid Programme (MAP) recipients tested positive for HBsAg and 3.70% (95% CI, 3.25-4.15) testedpositive for anti-HCV Ab. The total target population for liver cancer screening in 2008 included 433,822 adultsover 40 years of age. Of them, 141,381 (32.6%) participated in the NCSP for liver cancer. Participation rates were34.9% for National Health Insurance (NHI) recipients and 25.2% for MAP recipients. Among participants, 1,139individuals exhibited a positive screening result (recall rate = 0.81%).
Conclusions: Our findings demonstratethe current status of liver cancer screening in Korea. They provide evidence for implementing an organised livercancer screening programme among high-risk groups.
