Microwave ablation matches surgical resection for liver metastases

In a cohort study involving 1,027 patients with colorectal liver oligometastases, survival outcomes between microwave ablation (MWA) and surgical resection (SR) were compared. After a median follow-up of 39.8 months, no significant differences were found in overall survival rates (MWA: 70.6 months vs. SR: 83.2 months) or progression-free survival (MWA: 18.5 months vs. SR: 22.3 months). The presence of 3-5 intrahepatic nodules and surgical resection were identified as independent risk factors for survival.
