RETRACTED ARTICLE: Radiofrequency ablation versus hepatic resection for breast cancer liver metastasis: a systematic review and meta-analysis

To evaluate the comparative therapeutic efficacy of radiofrequency ablation (RFA) and hepatic resection (HR) for breast cancer liver metastases (BCLMs). Studies that had examined the outcomes for both RFA and HR for BCLM were identified by searching the electronic databases PubMed, EMBASE, and the Cochrane Library. Pooled analyzes of the overall survival (OS), disease-free survival (DFS), and short-term outcomes of BCLM were performed. Patients with BCLM gained many more survival benefits from HR than from RFA with regard to the 3-year OS rate (combined odds ratio (OR) 0.41, 95% confidence interval (CI) 0.29–0.59, P
