NCT07669727

Brief Summary

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

Study Arms (1)

Unresectable Hepatocellular Carcinoma

Patients with unresectable hepatocellular carcinoma (HCC) with tumor sizes 1-8cm. Patients will be candidates for TheraSphere Microspheres and planning to undergo the procedure as part of their treatment plan.

Device: TheraSphere

Interventions

Placement of TheraSphere Microspheres into the area of the primary tumor using multicompartment dosimetry instead of single compartment dosimetry

Unresectable Hepatocellular Carcinoma

Study Population

Participants will be selected from U.S. centers that are participating in the trial. Patients at these centers who are planning to undergo TheraSphere Microsphere treatment for their hepatocellular carincoma will be considered for this study.

You may qualify if:

  • TheraSphere Microspheres treatment determined as the optimal therapy
  • Have unresectable solitary HCC
  • Treatment Naïve
  • ECOG 0 or 1
  • Adequate liver function
  • Adequate renal and marrow function
  • Negative pregnancy test and/or adequate contraception for the patient and his/her sexual partner

You may not qualify if:

  • Macrovascular invasion
  • Extrahepatic metastases
  • Previous or current ascites/encephalopathy
  • Previous liver radiation, TACE, or systemic therapy for the disease
  • History of organ allograft including bone marrow
  • Any significant comorbities or contraindications to TheraSphere
