Comparative efficacy of stereotactic body radiotherapy and percutaneous radiofrequency ablation for oligometastatic liver disease—radiation oncologists’ perspective and practice guideline
Abstract
Abstract Localized treatment of oligometastatic liver disease can improve both local control and survival. The liver is a frequent site of metastases from colorectal, breast, and lung cancers, but most patients are not eligible for surgical resection due to lesion number, location, or comorbidities. For these patients, non-surgical ablative methods such as radiofrequency ablation (RFA) and stereotactic body radiotherapy (SBRT) are widely used. While RFA has been the traditional approach, SBRT is emerging as a promising alternative, offering precise, non-invasive treatment. SBRT may be especially useful for larger lesions or tumors in locations where RFA is difficult to perform. However, high-quality evidence and large-scale trials are still needed to confirm its efficacy and define its role. This review compares the strengths and limitations of both methods and provides practical guidance for clinical decision-making in the treatment of patients with inoperable liver metastases.
