Y-90 Radioembolization Safe and Achieves 100% Objective Response in High-Risk Liver Adenomas

In 12 patients with high-risk hepatocellular adenomas, Y-90 radioembolization achieved a 100% objective response rate (20/20 target lesions), with 85% complete response and no grade ≥2 adverse events.

• - Grade 1 adverse events (fatigue, nausea, etc.) occurred in 75% of patients; no grade 2 or higher events were observed.
• - Objective response rate was 100% (20/20 target lesions) with 85% complete response; no lesions ruptured or progressed during median 17.7-month follow-up.
• - This was a small retrospective single-center experience (n=12), and the authors call for larger prospective studies with longer follow-up.
