Abstract
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.
Aims: This study aims to conduct a randomized controlled clinical trial comparing the efficacy of IRE with RFA 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: Forty-eight patients had been recruited from 5 centers, of which, 33 patients (median age, 59.1 years) with 38 tumors had completed the 1-month follow-up and 21 patients have complete the 3-month follow up, with 2.3 months median follow up period. The mean largest tumor diameter is 3.9 cm. 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 procedure. One major adverse event (AE) was occurred in the control group.
Conclusion: 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.
期刊介绍：
World Journal of Surgical Oncology publishes articles related to surgical oncology and its allied subjects, such as epidemiology, cancer research, biomarkers, prevention, pathology, radiology, cancer treatment, clinical trials, multimodality treatment and molecular biology. Emphasis is placed on original research articles. The journal also publishes significant clinical case reports, as well as balanced and timely reviews on selected topics.
Oncology is a multidisciplinary super-speciality of which surgical oncology forms an integral component, especially with solid tumors. Surgical oncologists around the world are involved in research extending from detecting the mechanisms underlying the causation of cancer, to its treatment and prevention. The role of a surgical oncologist extends across the whole continuum of care. With continued developments in diagnosis and treatment, the role of a surgical oncologist is ever-changing. Hence, World Journal of Surgical Oncology aims to keep readers abreast with latest developments that will ultimately influence the work of surgical oncologists.
