Tumor ablation destroys a target lesion in situ using thermal or non-thermal energy delivered through a needle electrode, offering an organ-sparing, repeatable option for selected tumors of the liver, kidney, lung, and bone.
Clinical context
This article examines irreversible electroporation for cancer treatment mechanism technical considerations and emerging applications within the wider field of oncology ablation. Irreversible electroporation is a non-thermal option that spares adjacent structures such as ducts and vessels near the treatment zone. Patient selection based on tumor size, number, and location strongly influences local control.
Key considerations
- Irreversible electroporation is a non-thermal option that spares adjacent structures such as ducts and vessels near the treatment zone.
- Patient selection based on tumor size, number, and location strongly influences local control.
- Radiofrequency and microwave ablation generate lethal heat within the tumor, with microwave offering faster, larger, and less heat-sink-sensitive zones.
- Image guidance with ultrasound, CT, or fusion techniques is essential to accurate probe placement and complete tumor coverage with an adequate margin.
Diagnosis and evaluation
Careful patient selection and imaging-based evaluation underpin good outcomes in this area. Terminology that frequently arises includes radiofrequency ablation, microwave ablation, cryoablation, ablation margin. A structured assessment helps match the individual patient to the most appropriate treatment pathway.
Treatment approaches and technologies
Radiofrequency and microwave ablation generate lethal heat within the tumor, with microwave offering faster, larger, and less heat-sink-sensitive zones. A range of device technologies supports contemporary practice in oncology ablation.
