Background
There is currently no clear consensus on the relative suitabilities of laparoscopic hepatectomy (LH) and radiofrequency ablation (RFA) as minimally invasive treatment for small hepatocellular carcinoma (HCC).
Methods
In this retrospective study, we enrolled 156 patients with a single, small HCC with nodular diameters <4 cm and compared recurrence-free survival (RFS) and overall survival (OS) between patients treated with LH and control patients treated with RFA (n = 78 each). The groups were selected according to predefined criteria and matched in terms of their baseline clinical characteristics.
Results
During a median follow-up of 31.2 months, the 1-, 2-, and 3-year OS rates in the LH group were 96.2, 91.3, and 84.1 %, respectively, compared with 96.2, 82.6, and 78.8 % in the RFA group. The corresponding RFS rates were 82.1, 71.5, and 60.0 % in the LH group and 65.4, 47.7, and 37.6 % in the RFA group. Combined RFS rates were significantly higher in the LH groups (P = 0.006), but there was no significant difference in OS rates (P = 0.510). The incidence of postoperative complications was significantly lower in the RFA group (28.2 vs. 10.3 %, P = 0.004), and operation duration, intraoperative blood loss and blood transfusion, use of total parenteral nutrition, and length of stay as indicators of minimal invasiveness were also significantly better in the RFA group.
Conclusions
There was no difference between LH and RFA in terms of OS in patients with a single, small HCC. However, RFA was less invasive than the LH, but LH was associated with increased RFS.
