Impact of breast density on the efficacy of radiofrequency ablation in early-stage breast cancer.

ABSTRACT:

Background

Radiofrequency ablation (RFA) is a minimally invasive technique employed in the management of small breast tumors. RFA involves the delivery of a high-frequency current through a needle electrode under ultrasound guidance. In Japan, RFA has been covered by insurance since 2023 as a localized treatment option for early-stage breast cancers.

Methods

We retrospectively analyzed the data of patients who underwent RFA at our institution between February 2016 and March 2025. Breast density was classified into four categories based on the Breast Imaging Reporting and Data System. Associations between breast density and RFA parameters, including ablation temperature, time, and impedance, were evaluated.

Results

A total of 50 breasts in 49 female patients were treat
