Ablation of liver metastases: current status

Area of Science:

• Oncology
• Interventional Radiology

Background:

• Local ablative therapies are increasingly used for liver metastases.
• Radiofrequency ablation (RF ablation) has shown significant success in colorectal cancer, with 5-year survival rates reaching 55%.

Purpose of the Study:

• To review the literature on radiofrequency ablation, microwave ablation, and cryoablation for liver metastases.
• To evaluate the effectiveness of these ablative techniques in treating metastatic disease to the liver.

Main Methods:

• Systematic review of published literature.
• Analysis of outcomes for RF ablation, microwave ablation, and cryoablation in liver metastases.

Main Results:

• RF ablation has demonstrated high survival rates in colorectal cancer liver metastases.
• Published results for microwave ablation and cryoablation in liver metastases are promising.
• Evidence for selected patients with other malignancies is limited but suggests potential benefit.

Conclusions:

• Local ablative therapies are effective for liver metastases, particularly in colorectal cancer.
• Microwave ablation and cryoablation show promise and require further investigation.
• Continued evaluation of outcomes is essential for optimizing treatment strategies.
