Abstract
INTRODUCTION
Obtaining tumor-free margins during breast conservative surgery (BCS) is essential to avoid local recurrence and frequently requires reoperation. Radiofrequency ablation (RFA) of surgical margins after lumpectomy seems to be a helpful tool to avoid reoperations, but evidence is insufficient. This study analyzes the efficacy and safety of RFA after BCS to obtain free surgical margins.
METHODS
Non-randomized experimental study performed in an intervention group of 40 patients assigned to receive RFA after lumpectomy and successive resection of surgical margins, and a historical control group of 40 patients treated with BCS alone. In the intervention group, the RFA effect on tumor cell viability in the surgical margins was analyzed. Also, reoperation rate, complications and cosmetic results were compared in both groups.
RESULTS
A total of 240 excised margins were analyzed after RFA, obtaining a high number of tumor-free margins. Compared to the control group, the reoperation rate decreased significantly (0% vs 12%; P=.02), without differences in terms of postoperative complications (10% vs 5%; P=.67) or cosmetic results (excellent or good 92.5% vs 95%; P=.3).
CONCLUSIONS
RFA after lumpectomy is a reliable, safe and successful procedure to obtain tumor-free surgical margins and to decrease the reoperation rate without affecting complications or compromising cosmetic results.
