Precision radiation zaps untreatable liver tumors in tiny pilot study
NCT ID NCT04903548
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested a procedure called selective internal radiation therapy (SIRT) using Y-90 resin microspheres (SIR-Spheres) in one patient with liver cancer that could not be removed by surgery. The goal was to see if a flexible dosing approach could improve outcomes like tumor shrinkage, survival, and treatment costs. The study is complete but very small, so its findings are preliminary.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Y-90 resin microspheres (SIR-Spheres)
- What this could lead to
- If successful, this approach could offer a more precise way to deliver radiation to liver tumors, potentially improving tumor control and survival while reducing side effects.
- What could go wrong
- This was a very small, single-center study with only one participant, so results may not apply to others. The procedure carries risks like radiation damage to healthy liver tissue or lungs.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Age 18 years or older * All patients diagnosed with unresectable HCC in two of fewer hepatic segments at MDMC who undergo at least one SIRT procedure with Y-90 resin microspheres (SIR-Spheres®, Sirtex Medical Limited, Sydney, Australia) will be included in data capture. HCC is considered unresectable if it is multifocal or bilobar, or if the patient has malignant portal vein thrombosis, portal hypertension, or decompensated liver disease (Child-Pugh B or C). * Eligible cases for inclusion are those that would have undergone Y-90 resin SIRT and had an Eastern Cooperative Oncology Group (ECOG) performance status score of 0 to 2; platelets \>60,000; creatinine \<2 mg/dL; bilirubin \<2 mg/dL; and international normalized ratio (INR) \<1.2. Exclusion Criteria: * Subjects that do not meet the inclusion criteria * Patients are not eligible for SIRT if they had any extrahepatic disease; contraindication to hepatic artery catheterization such as vascular abnormalities, bleeding diathesis, allergy to contrast dye, concurrent malignancy, refractory ascites, previous external beam radiation, or evidence of any uncorrectable flow to the gastrointestinal tract; or greater than 30 Gy of radiation estimated to be delivered to the lung based on angiography or Tc-99 microaggregated albumin scan (shunt fraction of 20% or greater).
