Abstract
Aim: The present study aimed to compare the long-term survival outcomes of hepatic resection (HR) and radiofrequency ablation (RFA) in patients with single small (≤2 cm) hepatocellular carcinoma (HCC).Materials & methods: This retrospective study enrolled patients with a single small HCC measuring 2 cm or smaller underwent HR or RFA as their initial treatment.Results: Overall survival (OS) was significantly higher in the HR group than in the RFA group, while no significant difference was observed in recurrence free survival (RFS) between the two groups. However, after propensity score matching, both OS and RFS in the HR group were significantly higher than in the RFA group. Multivariate analysis showed that patients with hepatitis B virus infection, elevated prothrombin-induced by vitamin K absence or antagonist-II, and albumin-bilirubin (ALBI) grade 2/3 before treatment had poorer OS. Patients with ALBI grade 1 in the HR group demonstrated the highest OS.Conclusion: HR showed significantly better long-term OS and RFS compared with RFA in patients with as a single HCC (≤2 cm). Moreover, the ALBI grade may help identify patients who would benefit from HR or RFA.
