Percutaneous hepatic ablation: what needs to be known in 2014

Area of Science:

• Interventional Radiology
• Hepatobiliary Oncology

Background:

• Percutaneous ablation for liver tumors was initially limited to inoperable patients with small, few tumors.
• Technological and technical advancements have expanded the use of these minimally invasive treatments.
• Monopolar radiofrequency ablation (RFA) remains dominant but faces competition from second-generation microwave ablation (MWA).

Purpose of the Study:

• To review the evolving indications for percutaneous ablation in liver tumor treatment.
• To discuss the impact of new techniques and technologies on patient selection.
• To guide clinical decision-making based on patient factors and available technologies.

Main Methods:

• Literature review of percutaneous ablation techniques for liver tumors.
• Analysis of current clinical practices and technological trends.
• Discussion of factors influencing the choice between RFA and MWA.

Main Results:

• Percutaneous ablation is increasingly used in broader patient groups and complex strategies.
• The choice of technique is influenced by institutional expertise and available technology.
• Second-generation MWA presents a significant alternative to traditional RFA.

Conclusions:

• Percutaneous ablation is a versatile tool for liver tumor management, with expanding indications.
• Optimal patient selection and technique choice are crucial for successful outcomes.
• Continued technological innovation will likely further broaden the role of percutaneous ablation.
