The effect of radiofrequency ablation vs. liver resection on survival outcome of colorectal liver metastases (CRLM): a meta-analysis.

Background/aims: For patients with solitary colorectal liver metastasis (CRLM), it is still controversial whether radiofrequency ablation (RFA) has the same effect as liver resection (LR). This study aims to pool available evidence and to analyze the effect of RFA versus LR for resectable solitary CRLM in sur- vival indicators.

Methodology: Relevant studies were searched among databases and a meta-analysis was performed to pool the hazard ratio (HR) of RFA versus LR in overall survival (OS) and disease free survival (DFS).
