Microwave ablation versus radiofrequency ablation for subcapsular hepatocellular carcinoma: a propensity score-matched study.

•Compared to radiofrequency ablation, microwave ablation showed better local tumor control for patients with subcapsular hepatocellular carcinoma. •Microwave ablation showed similar major complication rates for patients with subcapsular hepatocellular carcinoma. •Microwave ablation may be preferred for patients with subcapsular hepatocellular carcinoma when they need to receive thermal ablation.
