Efficiency and safety of percutaneous ultrasound-guided radiofrequency ablation for right adrenal metastases from hepatocellular carcinoma / 中华超声影像学杂志

ABSTRACT

Objective:To retrospectively summarize and evaluate the efficiency and safety of percutaneous ultrasound-guided radiofrequency ablation (RFA) for adrenal metastasis (AM) from hepatocellular carcinoma (HCC).Methods:From October 2009 to September 2018, 16 patients with AM from HCC who underwent percutaneous RFA in the First Affiliated Hospital of Sun Yat-Sen University were enrolled in the study. The complete ablation and local tumor progression rates were elevated, and the side effects and complications were summarized.Results:The median ablation time of AM was 16 min. The complete ablation rate was 87.5% (14/16). After the follow-up period of 3 to 55 months, among the patients with complete ablation, there were 3 patients were detected local tumor progression (LTP), the LTP rate was 21.4% (3/14). As for the side effects and complications, 3 patients were diagnosed as hypertension crisis (3/16, 18.8%), 2 showed reduced heart rate and 1 of them exhibited frequent premature ventricular contraction which resulted in termination of ablation. There was no ablation-related death or adrenal failure.Conclusions:Percutaneous US-guided RFA is safe and effective in the treatment of AM originated from HCC.
