Microwave ablation versus resection for colorectal cancer liver metastases – A propensity score analysis from a population-based nationwide registry

Introduction Many previous studies comparing liver resection versus thermal ablation for colorectal cancer liver metastases (CRCLM) are subject to severe selection bias. The aim of this study was to compare survival after microwave ablation (MWA) versus liver resection for CRCLM in a population-based cohort study using propensity score analysis to reduce confounding by indication. Methods All patients undergoing liver resection or MWA as a first...
