Objectives: Surveillance for liver cancer has been shown to improve survival via earlier cancer detection. Although liver cancer surveillance is conducted at national level in Korea, little is known of the diagnostic performance and adherence to this surveillance, especially in a real surveillance setting. The purpose of this study was to evaluate the adherence and diagnostic accuracy of the liver cancer surveillance in real practice setting in Korea. Methods: We used the National Health Insurance Service claims data linked with the National Liver Cancer Surveillance Program (NLCSP) from 2013 to 2015. We analyzed the surveillance adherence and diagnostic accuracy. Sensitivity, specificity, and positive predictability values were assessed based on patients diagnosed with liver cancer within 3, 6, or 12 months after undergoing surveillance during the study period. Results: The annual surveillance rate resulted that individuals undergoing the NLCSP was 41.2% in 2014. Female, the younger, and people with less comorbidity and more income received more surveillance. The sensitivity of the surveillance program was 37.0% and 40.4% for positive predictive value and it was varied depending on the criteria used to define the diagnosis of liver cancer. Conclusion: This study highlights the current status of the NLCSP and the needs for continues efforts to help improve the current surveillance practice in quantitative and qualitative to fulfil the goal of NLCSP.
