ABSTRACT

Objective To evaluate the efficacy of radiofrequency ablation in breast-conserving surgery followed neoadjuvant chemotherapy.Methods Retrospective analysis of 30 cases of breast cancer patients admitted to Beijing Friendship Hospital,Capital Medical University from April 2015 to September 2018.The average age was 54.3 years and the range was 28 to 70 years.For breast invasive ductal cancer,patients underwent breast-conserving surgery after neoadjuvant chemotherapy,and then received radiofrequency ablation.The clinical and pathological characteristics,postoperative complications,recurrence and metastasis,and cosmetic effects were observed.Results All 30 patients with breast-conserving surgery successfully completed radiofrequency ablation.The average outpatient follow-up was 22.5 months,ranging from 2 to 43 months,without local recurrence or metastasis;skin burns occurred in 2 cases (6.67％),and solid nodules formed in situ in 6 cases (20.00％);cosmetic satisfaction rate was 86.67％ (26/30).Conclusions The radiofrequency ablation techniques applied in breast-conserving surgery have a high rate of technical success with relative low complication rates.And the radiofrequency ablation techniques may improve the cosmetic results after breast-conserving surgery and enhance local control.
