Key clinical point: First-line radiofrequency ablation (RFA) is associated with worse long-term therapeutic outcomes for single periportal hepatocellular carcinoma (HCC) than for single nonperiportal HCC.
Main finding: At 1 and 5 years, periportal vs nonperiportal HCC was associated with significantly higher local tumor progression rates (15.7% and 46.9% vs 6.0% and 28.7%, respectively; P = .007) and worse overall survival rates (81.3% and 42.9% vs 99.3% and 78.1%, respectively; P < .0001).
Study details: The data come from a retrospective study involving 233 patients with HCC, either periportal (n=56) or nonperiportal (n=177), who underwent percutaneous RFA alone or combined with transarterial chemoembolization as first-line treatment.
Disclosures: The authors reported no funding source or conflict of interests.
