Radiofrequency Ablation for the Treatment of Hepatocellular Carcinoma Just Below the Hepatic Capsule

Background/Objectives: During radiofrequency ablation (RFA) for the treatment of hepatocellular carcinoma (HCC), electrodes are generally inserted into the center of the tumor through the hepatic parenchyma under image guidance, including ultrasound or computed tomography (CT) guidance. However, tumors located just below the hepatic capsule require special puncture techniques. This retrospective study aimed to analyze the efficacy and outcomes of RFA for HCC located just below the subcapsular region of the liver.

Methods

A total of 81 patients with 81 subcapsular HCC tumors underwent RFA. Baseline patient characteristics, treatment results, and adverse events were investigated. Factors associated with local recurrence were also examined.
