Objective: This study aimed to evaluate the efficacy, feasibility, and tolerability of ultrasound (US)-guided percutaneous microwave ablation (MWA) for treating hepatocellular carcinoma (HCC) originating in the caudate lobe. Materials and Methods: The treatment and survival parameters of 32 patients with HCC in the caudate lobe, who met the inclusion criteria and had received US-guided percutaneous MWA in our department from November 2010 to October 2015, were retrospectively analyzed. Imaging examination (contrast-enhanced computed tomography or magnetic resonance) 1 month after MWA was used to evaluate the efficacy of US-guided MWA. Results: Thirty-two patients underwent percutaneous MWA for caudate lobe HCC. The average tumor size was 3.42 ± 0.27 (range: 1–6.8) cm. The initial complete ablation (CA) rate was 87.5% (28/32), and the total CA rate was 96.88% (31/32). Furthermore, the median length of hospitalization was 4 days (range: 2–10 days), and no major complication was observed in this study. The overall survival rates were 87.5%, 50%, and 28.13% at 1, 2, and 3 years, respectively. The progression-free survival after MWA was 93.75%, 53.15%, and 28.13% at 6, 12, and 18 months, respectively. Conclusions: US-guided percutaneous MWA was a safe and effective treatment. It is a promising alternative therapy for HCC originating in the caudate lobe.
