Abstract
BACKGROUND
Primary liver cancer is one of the most lethal malignancies in the world. Traditional treatment methods have limitations in terms of efficacy and safety. Radiofrequency ablation (RFA) guided by B-ultrasound, as a minimally invasive treatment, has attracted increasing attention in the treatment of primary liver cancer in recent years.
AIM
To study the efficacy and safety of RFA were compared with those of traditional surgery (TS) for treating small liver cancer.
METHODS
At least 2 people were required to search domestic and foreign public databases, including foreign databases such as EMBASE, PubMed and the Cochrane Library, and Chinese databases such as the China National Knowledge Infrastructure database, China Biomedical Literature database, Wanfang database and VIP database. Controlled trials of RFA vs conventional surgery for small liver cancer were retrieved from January 2008 to January 2023. They were screened and evaluated according to the quality evaluation criteria in the Cochrane Handbook of Systematic Reviews. The meta-analysis was performed using RevMan 5.3 software.
RESULTS
A total of 10 studies were included in this study, including 1503 patients in the RFA group and 1657 patients in the surgery group. The results of the meta-analysis showed that there was no significant difference in 1-year overall survival between the two groups (P > 0.05), while the 3-year and 5-year overall survival rates and 1-year, 3-year and 5-year tumor-free survival rates in the surgery group were greater than those in the RFA group (P < 0.05). In terms of complications, the incidence of complications in the RFA group was lower than that in the surgery group (P < 0.05).
CONCLUSION
In terms of long-term survival, TS is better than RFA for small liver cancer patients. However, RFA has fewer complications and is safer.
Core Tip: To evaluate the efficacy and safety of B-ultrasound-guided radiofrequency ablation (RFA) in the treatment of primary liver cancer by meta-analysis. This study systematically searched a variety of medical databases, screened out clinical trials and observational studies that met the criteria, extracted relevant data, and used statistical methods for comprehensive analysis. The key indicators of RFA, such as tumor ablation success rate, patient survival rate, complication rate and postoperative recurrence rate, were mainly concerned. Through comparison and analysis, the aim is to provide more powerful evidence support for clinical practice, optimize the treatment strategy of primary liver cancer, and improve the quality of life and prognostic effect of patients.
