Primary study of radiofrequency ablation for early breast cancer with negative sentinel lymph node / 中华超声影像学杂志

ABSTRACT

Objective:To summarize the preliminary experience of percutaneous radiofrequency ablation(RFA) in the treatment of early breast cancer(the length of the lesion<15 mm) with negative sentinel lymph node(SLN), and to evaluate its feasibility and efficacy.Methods:From October 2016 to November 2019, 18 patients with early breast cancer(the length of the lesion<15 mm) treated in the First Affiliated Hospital of Zhengzhou University underwent FNAC of axillary SLN under the guidance of CEUS were enrolled. Patients with pathologically negative axillary SLN were treated with percutaneous RFA of breast cancer. The complete ablation rate and the relapse rate were evaluated. Intraoperative pain, postoperative complications and postoperative patient satisfaction were analyzed.Results:Eighteen patients underwent CEUS-guided FNAC of SLN, of which 1 case was positive and 17 cases were negative. Seventeen breast cancer lesions of the 17 negative patients underwent percutaneous RFA. The length of the lesions was 3.3-14.0 (8.2±3.9)mm, the complete ablation rate was 100%, the ablation time was 9-18 (12.8±2.7)min. During the follow-up of 9-46 months, no patient developed tumor progression. There were no serious complications related to RFA after operation. The patients′ satisfactory rate for postoperative appearance was 100%.Conclusions:RFA of early breast cancer(the length of the lesion<15 mm) with negative SLN is feasible and has the advantages of safety, minimal invasion and beauty.
