Objective:To study the overall survival rate(OS),complete ablation rate(CA),and local tumor progression rate(LTP)in different years after percutaneous radiofrequency ablation(PRFA)for breast cancer liver metastases(BCLM)by Meta-analysis,in order to obtain the basis of evidence-based medicine for the clinical efficacy of PRFA in BCLM.Methods:Cohort studies or case-control studies on PRFA in the treatment of BCLM were systematically searched from PubMed,Cochrane library,Embase,CNKI and Wanfang from database inception to September 2023.References were screened according to inclusion and exclusion criteria,quality assessment was carried out,and data were extracted.Stata 15.1 software was used for statistical analysis and forest map drawing.Results:A total of 10 case-control studies and cohort studies were included.A total of 312 patients were treated with PRFA for BCLM,with OS at 1,2,3 and 5 years of 86%,57%,56%,33%,CA of 94%and LTP of 16%.Conclusion:The Meta-analysis indicates that PRFA is effective in the treatment of BCLM.
