The Management of Colorectal Cancer Liver Metastases: The Interventional Radiology Viewpoint

"Comparison of Stereotactic Body Radiation Therapy and Radiofrequency Ablation in the Treatment of Intrahepatic Metastases" by Jackson et al is a thought-provoking addition to the literature concerning treatment of colorectal cancer metastasis (CLM). The benefits of hepatic CLM resection are well established; however, most patients are not candidates for resection. Local tumor ablation is a safe and effective alternative treatment for select patients. Considerable research has evaluated percutaneous ablation as treatment of CLM, including retrospective reviews with long-term follow-up and prospective randomized trials showing prolongation of progression-free and patient survival compared with chemotherapy alone.
