“…This study has a larger sample size than that of previous retrospective studies 25,28 . In addition, this study is a multicenter clinical trial, thus avoiding the selection bias caused by a single-center design and the information bias caused by differences in medical conditions and doctors' experience levels.…”

“…Previous studies have compared the effects of IRE and RFA, but were all retrospective in nature and nonrandomized prospective study. For example, Thamtorawat et al 25 retrospectively evaluated 42 patients with HCC who underwent IRE and RFA from January 2014 to September 2020 and compared the e cacy and safety of these treatments. Biliary tract adverse events were found in one (7.7%) patient in the IRE group and ve (16.1%) patients in the RFA group.…”

Background At present, the main clinical application of local ablation therapy, such as radiofrequency ablation (RFA), is to heat the tissue to a certain temperature. However, high temperature will cause thermal damage. Irreversible electroporation (IRE) is a novel minimally invasive local ablation technology for tumors. By high-frequency pulse, the tumor cell membrane can be irretrievably perforated, resulting in the destruction of the intracellular environment, which can preserve important structures in the treatment area. However, there are no randomized controlled clinical trials comparing the efficacy of IRE with traditional local ablation in the treatment of liver cancer. Methods We will conduct a multicenter, randomized, parallel-controlled non-inferiority clinical trial to compare the efficacy and safety of IRE and RFA for hepatocellular carcinoma (HCC). One hundred and ninety patients with HCC from five academic medical centers will be enrolled. The patients will be randomized into treatment arm (IRE) and control arm (RFA). The primary outcome is the progress -free survival (PFS) and the key secondary outcome is the Overall survival (OS). Results Thirty-three patients have completed the 1-month follow-up. These 33 patients (median age, 59.1 years) have a total of 38 tumors, and the mean largest tumor diameter is 3.9 cm. In these 33 patients, no end point was observed for PFS or OS in both groups, and the complete ablation rate was 100% in both groups. The lesions in the IRE group showed obvious shrinkage 1 month after surgery. One major adverse event (AE) was occurred in the control group. Conclusions This is the first randomized controlled clinical trial to compare the clinical effects of IRE and RFA. The preliminary results suggest that both RFA and IRE are effective in the treatment of HCC, which can provide strong evidence for the use of IRE in HCC and provide more options for the treatment of patients with HCC. Clinical Trial Registration ClinicalTrials.gov, identifier NCT05451160.
