This table provides a comprehensive overview of the clinical outcomes and safety across various studies that evaluated microwave ablation in comparison with other ablation techniques such as radiofrequency ablation, hepatic resection, and other modalities. The table summarizes key metrics, including the follow-up duration, complication rates, local recurrence rates, overall survival, and disease-free survival. These metrics highlight the relative effectiveness and safety profiles of microwave ablation and its potential advantages or limitations in the treatment of colorectal liver metastases. MWA: Microwave ablation; RFA: Radiofrequency ablation; HR: Hepatic resection; HAI: Hepatic artery infusion; TACE: Transarterial chemoembolization.
