Abstract
Background: Ablation is an alternative treatment modality for selected patients with colorectal liver metastases (CRLMs). Although initially widely performed via radiofrequency ablation (RFA), more recently, microwave ablation (MWA) is being preferred due to its perceived superiority in creating the ablation zones. The aim of this study is to compare the long-term efficacy of these two modalities performed surgically. Methods: Patients undergoing surgical liver ablation from 2005-2023 at a tertiary center by a single surgeon for CRLM were included in a retrospective institutional review board-approved study. Outcomes were compared using Wilcoxon, Chi-square, Kaplan-Meier, and Cox multivariate regression analyses. Continuous data are presented as median (interquartile range). Results: the RFA group (P=0.005). Conclusions: . RFA.
