Yttrium-90 Radioembolization for Hepatocellular Carcinoma.

(90)Y radioembolization refers to the selective, transcatheter, and intra-arterial injection of micrometer-sized particles loaded with the radioisotope yttrium-90 for the treatment of primary and metastatic hepatic malignancies. In the treatment of intermediate- and advanced-stage hepatocellular carcinoma, (90)Y radioembolization provides favorable outcomes with minimal side effects, offering an alternative treatment option to other transarterial therapies, such as bland embolization and chemoembolization. This review provides an overview of the use of (90)Y radioembolization in the treatment of hepatocellular carcinoma, including patient selection criteria, dosimetry, and clinical outcomes.
