Abstract

To investigate the results of radiofrequency ablation (RFA) in obtaining the necrosis of hepatocellular carcinoma (HCC) in cirrhotic patients and to assess the results of RFA in relation to recurrence of HCC and survival of the treated patients. Fifty-six consecutive cirrhotic patients with 63 HCCs were treated with RFA between May 2000 and May 2004. The diameter of the HCCs ranged from 1 cm to 5 cm (mean 2.8 cm). In all cases RFA was performed with percutaneous approach under ultrasound guidance using expandable needle electrode (LeVeen needle). Treatment efficacy and recurrence were evaluated with dual-phase spiral computed tomography (CT). Complete necrosis after single or multiple treatment was achieved in 96.8% (61/63) tumors. We observed recurrence after complete necrosis in 23 patients (41%) during a mean follow-up of 32.3 months. The recurrences were local in 2 patients (8.6%) and in different segments in 21 (91.4%). Major complications occurred in 3 patients (4%). During follow-up period, 32 (57.1%) patients died; 15 due to progression of HCC, 11 from liver failure, 3 from esophageal varices bleeding and 3 from the causes not related to liver disease. RFA with LeVeen needle is an effective and safe treatment for HCC<5 ...Continue Reading
