Comparison of high-intensity focused ultrasound therapy and radiofrequency ablation for recurrent hepatocellular carcinoma

Hepatocellular carcinoma (HCC), which accounts for more than 90% of primary liver cancer, is a major health problem worldwide, and is the third most common cause of cancer-related death. It is the fifth most prevalent cancer in men and the seventh in women (1-3). The prognosis for untreated HCC is generally poor, and curative treatments consist of surgical resection, radiofrequency ablation (RFA), and liver transplantation (1-3).
