A Post Approval Study to Evaluate Safety and Effectiveness of Multicompartmental Dosimetry Planning. (ADVANCE-MCD)

22. juni 2026 opdateret af: Boston Scientific Corporation

A Post Approval Single-arm Study Evaluating Transarterial Radioembolization Treatment for Hepatocellular Carcinoma Using Multicompartment Dosimetry Planning

The purpose of this study is to assess the safety and effectiveness of treating a tumor using a different planning method called MCD for the FDA-Approved device, TheraSphere.

TheraSphere Microspheres are microscopic radioactive glass spheres that deliver radiation therapy in the liver tissue where they are placed. This study investigates a procedure called multicompartment dosimetry (MCD). When using a multicompartment dosimetry approach, the doctor will look at images of the liver to see where there is tumor to determine where to treat. That area will be divided into "compartments" where the dose to tumor and the healthy liver are calculated separately. The goal of MCD is to give the tumor a higher radiation dose while protecting more of the healthy part of the liver.

Traditional planning for the TheraSphere Microspheres procedure uses single compartment dosimetry (SCD) which treats the tumor and the healthy liver as one area so the dose is more evenly distributed and the dose to the tumor may be lower than with the MCD approach. The single compartment approach is standard and is well established however this research study is to see if giving TheraSphere Microspheres with an MCD planning method is safe and effective by evaluating the effect of radiation on the liver as well as how the tumor responds to higher doses
