Efficacy and safety of microwave ablation for benign breast lesions: a systematic review and meta-analysis.

We performed a systematic review and meta-analysis to evaluate the efficacy and safety of microwave ablation (MWA) for benign breast lesions.

PubMed, Embase, Web of Science, Cochrane Library databases, China National Knowledge Infrastructure, and Wanfang Data Knowledge Service Platform databases were searched.

A total of 10 studies were included, giving a sample size of 1241 patients and 2729 benign breast lesions. The first complete ablation success rate was 96%. The volume reduction ratio (VRR) after 3/6/12 months was 47.4%, 62.1%, and 85.8%, respectively. After 12 months, the lesion disappearance rate was 53.6%, and the efficiency rate was 99%. The rate of excellent cosmesis was 88% and the rate of good cosmesis was 10%. The complication rate was 2%.

MWA is safe and effective for treating benign breast lesions. It can be a promising minimally invasive choice for benign breast lesions.
