Y-90 Treatment Response Using Transarterial Radioembolization

Summary

This prospective clinical study will examine the ability of contrast-enhanced ultrasound (CEUS) to assess the treatment response of hepatocellular carcinoma (HCC) to transarterial radioembolization (TARE). HCC is the third leading cause of cancer mortality worldwide and the single fastest growing cause of cancer mortality in the United States. TARE is recommended for 15-25% of HCC patients. Treatment response is generally evaluated using contrast-enhanced Computed Tomography (CT) or Magnetic Resonance Imaging (MRI) 1-2 months and 4-6 months post-TARE. Although TARE is an effective therapy, assessment of treatment response using CT/MRI is challenging because CT/MRI frequently diagnoses tumor response as equivocal or non-progressing for up to 6 months post-TARE based on Liver Imaging Reporting and Data System (LI-RADS) criteria. This delay in diagnosing tumor viability subsequently delays needed retreatment and can even serve as a barrier to transplantation. Our prior work in HCC locoregional therapy has shown CEUS provides improved sensitivity in detecting viable tumor following transarterial chemoembolization relative to traditional CT/MRI. Therefore, the investigators propose to evaluate both qualitative and quantitative CEUS as a tool for evaluating HCC post-TARE at similar time points of clinically recommended cross-sectional imaging, while also investigating the role of Kupffer phase imaging. The investigator plans to enroll a total of 30 patients scheduled for TARE of a treatment naïve HCC over an 18-month period, allowing for a minimum of 6 months follow up. Patients will undergo a CEUS examination within two weeks of their first two clinically indicated CT/MRI exams (obtained at Jefferson 1-2 months and 4-6 months post TARE). Patients will be recruited across six major hospitals within the Jefferson Health Enterprise. Those eligible for participation will be identified by project co-investigators and contacted by the study coordinator to discuss participation and to explain the study. The patient will be given time to consider the risks and benefits of the study and ask questions about participation. If agreeable, the patient will then arrange with the project coordinator to come to Jefferson's center city campus to sign consent and take part in the research study.
