Core Tip
Core Tip: The role of stereotactic body radiotherapy (SBRT) in hepatocellular carcinoma is evolving within contemporary treatment guidelines. In this prospective real-world registry, SBRT achieved durable local control with minimal toxicity across curative, bridging-to-transplant, and salvage indications, including patients with impaired liver function and advanced disease. Despite excellent in-field control, out-of-field intrahepatic progression was the dominant failure pattern, highlighting the importance of integrating SBRT within multidisciplinary, stage-adapted treatment pathways.
