A Phase 1 Study of Combined Y-90 Selective Internal Radiation Therapy (Y-90 SIRT) and Stereotactic Body Radiation Therapy (SBRT) in Unresectable Hepatocellular Carcinoma (HCC)

This study will investigate the combination of Ytrium-90 (Y-90) Selective Internal Radiation Therapy (SIRT) followed by Stereotactic Body Radiation Therapy (SBRT). Y-90 SIRT alone or SBRT alone are standard procedures used in the treatment of liver cancer. This study will assess the combination of Y-90 SIRT and SBRT and obtain preliminary information about the side effects and safety of the combination therapy. Additionally, this is the first time that Y-90 PET-CT imaging will be included in planning for SBRT.
