Minimally invasive percutaneous ablative therapies for HCC
- Percutaneous ablative techniques for local control of HCC can be divided into two categories: thermal ablation and chemical ablation.
- Thermal ablation techniques alter the temperature of the tumor to cause cell death and include heat-based methods (radiofrequency ablation [RFA], microwave ablation, laser ablation, high-intensity focused US) and cold-based methods (cryoablation).
- Chemical ablation involves injecting substances such as ethanol or acetic acid directly into the tumor to produce tissue necrosis.
