Abstract

To evaluate the clinical efficacy and safety of radiofrequency ablation (RFA) with surgical re-resection (SRR) in patients with postoperative recurrent hepatocellular carcinoma (RHCC) meeting the Milan criteria. A literature search was performed to identify comparative studies addressing outcomes of both RFA and SRR for RHCC meeting the Milan criteria. Pooled odds ratios (OR) with 95% confidence intervals (95% CI) were calculated using either the fixed effects model or the random effects model. Five nonrandomized controlled trials were included in the analysis. These studies included a total of 543 patients: 243 treated with RFA and 300 treated with SRR. The SRR group had a better 3-year recurrence-free survival rate compared with RFA group (OR 0.44, 95%CI 0.25-0.77, p=0.004). However, there were no obvious differences between RFA and SRR group in overall survival (OS) rates, re-recurrence rate and OS rates with tumors ≤ 3cm. What's more, the RFA group had a safety advantage with less complications of Clavien classification grade II or higher compared with SRR group (OR 0.21, 95%CI 0.05-0.94, p=0.04). RFA seemed to be superior to SRR in the treatment of patients with RHCC meeting the Milan criteria on account of clinical safety...Continue Reading
