Ultrasound-guided percutaneous microwave ablation in the treatment of large hepatocellular carcinoma in the cauda lobe (a report of 13 cases)

Abstract

Abstract: Objective To evaluate the safety and efficacy of microwave ablation for large primary liver tumor in the caudate lobe.Methods The clinical data of 13 patients with large primary liver tumors in the caudate lobe treated by microwave ablation in our hospital from December 2011 to September 2018 were collected. And the complete ablation rate, complications and prognosis of these patients were analyzed. Results All the 13 patients were ablated successfully.The complete ablation rate was 76.9% for the first ablation and the overall ablation rate was 92.3%.The 1-year, 2-year and 3-year overall survival rates were 84.5%, 74.0% and 49.4%, respectively. Ablation-related obstructive jaundice occurred in 2 patients, which subsided after treatment, and no death was observed.Conclusion For large tumors in the caudate lobe of the liver at high risk sites, microwave ablation is safe, effective and feasible. And it can be used as a potential treatment of non-resectable liver tumors.
