Clinical Report: Hepatectomy Shows Superior Outcomes Compared to Microwave Ablation
Overview
This study compares the clinical efficacy of hepatectomy and microwave ablation (MWA) for colorectal cancer liver metastases (CRLM). Results indicate differences in recurrence-free survival and overall survival between the two treatments.
Background
Colorectal cancer liver metastases (CRLM) are a common complication in colorectal cancer, affecting a significant proportion of patients. Surgical options such as hepatectomy have been shown to improve long-term survival, while MWA is increasingly used as a minimally invasive alternative.

Overall Survival

Complete Ablation Rate (lesions >3 cm)
Higher in non-high-risk
Lower in high-risk
Key Findings
Hepatectomy resulted in better recurrence-free survival (RFS) and overall survival (OS) compared to MWA.
MWA achieved complete ablation for lesions <3 cm, but had lower rates for lesions >3 cm, especially in high-risk locations.
Tumor diameter was identified as an independent risk factor for incomplete ablation in the MWA cohort.
High-risk lesions, particularly those larger than 3 cm, exhibited lower efficacy with MWA.
Patients with CRLM treated with hepatectomy had better long-term survival outcomes.
Clinical Implications
Hepatectomy may be more effective for patients with CRLM, particularly for larger tumors or those in high-risk locations.
Conclusion
Hepatectomy demonstrates better outcomes compared to MWA for CRLM, particularly for larger and high-risk lesions.
