Abstract
BackgroundLaparoscopic liver resection (LLR) and radiofrequency ablation (RFA) play central roles to treat early-stage hepatocellular carcinoma (HCC, ≤3 cm, 1–3 nodules, and no macrovascular involvement), although data are lacking regarding whether LLR or RFA is preferable. This study aimed to compare outcomes of both treatments for small HCCs. MethodsTreatment outcomes of small HCCs were compared between all the minor LLRs performed between 2005 and 2016 and RFAs performed between 2011 and 2016 at Kyoto University. ResultsA total of 85 and 136 patients underwent LLR and RFA, respectively. Patients that underwent LLR had higher incidence of blood transfusions, complications, and longer hospital stay. Overall and disease-specific survival rates were similar between LLR and RFA; however, recurrence-free (49.2% vs. 22.1% at 3-year) and local recurrence-free survival rates (94.9% vs. 63.6% at 3-year) were higher after LLR. Multivariate analyses identified that multiple nodules and 65-year-old and above are predictors of disease-specific survival, and that RFA is a predictor of recurrence and local recurrence. ConclusionRFA is less invasive, although both LLR and RFA are safe and effective. LLR provides better local control with superior recurrence-free and local-recurrence free survival. These results help optimize treatment selection based on patient-specific factors.
