结局指标
主要结局
Technical success
时间窗: Immediately after radiofrequency ablation
Technical success addresses whether the index tumor was treated according to a predefined protocol and entirely covered by the ablation zone.
Local tumor progression rate
时间窗: 12 months after radiofrequency ablation
Local tumor progression, defined as the appearance of tumor foci at the margin of the ablation zone after the attainment of treatment success.
次要结局
- Complication after radiofrequency ablation(Immediately, 1 month, 3 months, 6 months, 9 months, and 12 months after radiofrequency ablation)
- Recurrence-free survival(12 months after radiofrequency ablation)
