About this trial
At four major centers in Korea, patients with hepatocellular carcinoma (HCC) that exceed the up-to-7 criteria yet remain locally confined will undergo ablative radioembolization using Yttrium-90 glass microspheres, guided by a standardized dosimetry method. Their treatment response, survival outcomes, and adverse events will be monitored for two years following the procedure.
