Comparison with Other Minimally Invasive Techniques

Radiofrequency ablation is only one of many minimally invasive techniques, and other techniques include PEI, chemoembolization, and microwave, laser, or cryo-ablations. There are at least two studies comparing the outcome of RF ablation with PEI.[56,63] They showed that complete tumor necrosis was better (90% versus 80% to 85%) and local tumor recurrence was lower (2% versus 7%) with RF ablation when compared with PEI. Another advantage was the fewer number of sessions (1.2 to 1.3 versus 3.3 to 4.8) required with the RF ablation technique. However, there is paucity of literature providing a direct comparison between RF ablation and other techniques.
