ABSTRACT
Radiofrequency ablation [RFA] is a well known therapeutic modality in the curative treatment of hepatocellular carcinoma [HCC]. The aim of this work was to assess the efficacy of percutaneous RFA in patients with tumors 400 ng/ml] and/or typical pattern of triphasic CT examination. RFA was employed to all patients. Triphasic CT examination was performed 1 month after the end of procedure and at three months interval for one year of follow up. Ultrasound examination and AFP were performed at 3 months interval for the same follow up period. Recurrence was considered when typical criteria were detected at triphasic CT examination. The results showed that full necrosis of the tumor was achieved in 42 patients in group I [93.3%] and in 41 patients in group II [93.18%]; [P>0.05]]. Recurrence after 1 year was detected in 11 patients of group I [26.19%] and 12 patients of group II [29.27%], [P> 0.05]
