Key clinical point: Microwave ablation may be a safe and effective first-line locoregional therapy (LRT) for bridging patients with hepatocellular carcinoma (HCC) to liver transplant (LT), with no cases of waitlist removal due to tumor seeding, procedural adverse events, or local tumor progression.
Major finding: In total, 71 (80.7%) of 88 patients eventually received LT. None of the patients died while on the waitlist, and only 4.5% of patients dropped out due to tumor growth outside of the Milan Criteria. The 5-year post-transplant overall survival rate was 76.7%, with the overall and major adverse event rates being 5.1% and 3.0%, respectively.
Study details: Findings are from a single-center, retrospective study including 88 patients with HCC on the waitlist for LT who received percutaneous microwave ablation as the first-line LRT.
Disclosures: The study did not receive any funding. Some authors declared consulting for, being on the board of directors or a shareholder of, or receiving research support from various sources.
