위험도가 높은 환자의 간세포암종 감시 전향적 평가(간암 선별검사)

This prospective multicenter observational study evaluates the performance of a structured hepatocellular carcinoma (HCC) surveillance program in patients at increased risk of developing liver cancer. Participants will undergo routine surveillance with semiannual abdominal ultrasound reported using the Ultrasound Liver Imaging Reporting and Data System (US LI-RADS) and serum alpha-fetoprotein (AFP) testing as part of standard clinical care. The study aims to assess HCC detection rates, stage at diagnosis, detection of other hepatic malignancies, and the time intervals between detection, diagnosis, and treatment in a real-world setting. Approximately 300 participants will be enrolled and followed for up to 36 months.
