Summary
Radiofrequency ablation offers a curative option for unresectable liver metastases, with lower morbidity than cryoablation. Selective use of radiofrequency ablation improves tumor clearance in these patients.
Area of Science:
- Hepatobiliary surgery
- Interventional oncology
- Minimally invasive cancer treatment
Background:
- Surgical resection is the gold standard for liver metastases but often not feasible due to multifocality or insufficient remnant liver volume.
- Local ablative techniques aim to increase the number of patients eligible for curative treatment by selectively destroying tumors.
- Cryoablation and radiofrequency ablation show curative potential, while transarterial chemoembolization and alcohol injection are palliative.
Purpose of the Study:
- To evaluate the efficacy and safety of local ablative techniques for unresectable liver metastases.
- To compare cryoablation and radiofrequency ablation in terms of local recurrence and morbidity.
- To identify limitations of radiofrequency ablation and propose selective use for improved outcomes.
Main Methods:
- Review of local ablative techniques for liver metastases, focusing on cryoablation and radiofrequency ablation.
- Comparison of local recurrence rates and complication profiles between cryoablation and radiofrequency ablation.
- Analysis of specific limitations of radiofrequency ablation, including biliary and vascular proximity issues.
Main Results:
- Local recurrence rates for cryoablation and radiofrequency ablation are comparable and below 10%, contingent on selection criteria.
- Morbidity is significantly higher with cryoablation, favoring radiofrequency ablation in clinical practice.
- Radiofrequency ablation faces challenges with proximal biliary lesions and near-major vessel metastases due to heat dissipation effects.
Conclusions:
- Radiofrequency ablation is a preferred local ablative technique over cryoablation for unresectable liver metastases due to lower morbidity.
- Selective application of radiofrequency ablation, considering its limitations, can achieve complete tumor clearance in select patients.
- Further refinement in technique and patient selection can enhance the role of radiofrequency ablation in managing unresectable liver metastases.
