Summary
Local ablation techniques offer effective treatment for liver metastases when surgery is not an option. These methods, including microwave and radiofrequency ablation, provide comparable long-term control for select patients.
Area of Science:
- Oncology
- Interventional Radiology
- Hepatobiliary Surgery
Background:
- Liver metastases from solid tumors (e.g., colon, breast, neuroendocrine, sarcomas) have expanding treatment options.
- Non-resection methods are increasingly utilized for managing liver metastases.
Purpose of the Study:
- To review literature on local ablation techniques for liver metastases.
- To evaluate technique, perioperative, and long-term outcomes of ablation for liver metastases.
Main Methods:
- Literature review focused on liver metastases treatment.
- Analysis of outcomes specifically for local ablation techniques.
Main Results:
- Ablation modalities are popular for patients unsuitable for surgical resection.
- Local ablation, alone or combined with other therapies, extends survival and can offer disease-free survival rates similar to resection.
Conclusions:
- Surgical resection is optimal for liver metastasis, but local ablation offers similar long-term control in selected patients.
- Microwave ablation and radiofrequency ablation are key local treatment options.
