Overall survival and recurrence-free survival in the two groups. The 5-year overall survival rates were 61.1% and 39.5% in the SR and RFA groups, respectively. The 5-year recurrence-free survival rates were 40.2% and 22.3% in the SR and RFA groups, respectively. Both overall survival () and recurrence-free survival () were significantly higher in the SR group than in the RFA group. SR, three-dimensional visualization system-guided surgical resection; RFA, radiofrequency ablation.
