| description | Radiofrequency ablation (RFA) is recommended in Japan for patients with hepatocellular carcinomas (HCCs) one to three in number and ≤3 cm in size. The arfa<sup>®</sup> and VIVA<sup>®</sup> RFA systems are widely used for patients with HCC and this retrospective observational study aims to compare their performances. The study included 365 patients with HCCs one to three in number and ≤3 cm in size who underwent RFA using the arfa<sup>®</sup> system (arfa<sup>®</sup> group) or the VIVA<sup>®</sup> system (VIVA<sup>®</sup> group). The total bilirubin (T-Bil) level after RFA was higher in the arfa<sup>®</sup> group than in the VIVA<sup>®</sup> group. With a 3-cm electrode needle, the longest diameter (Dmax) and the shortest diameter were analyzed and found to be greater in the arfa<sup>®</sup> group than in the VIVA<sup>®</sup> group. Furthermore, Dmax with the 2.5-cm electrode needle was greater in the arfa<sup>®</sup> group than in the VIVA<sup>®</sup> group. Statistically significant differences in the ablation area and in the T-Bil value after RFA were observed between the groups; however, these differences are not considered clinical problems because the difference in the ablation area was only slight and the Child–Pugh score was the same between the groups. Thus, hepatologists can use either of the RFA systems based on their preference. |
