Accuracy of Intraoperative Frozen-Section Analysis of Breast Cancer Lumpectomy-Bed Margins

Intraoperative analysis of margins using FSA is effective at minimizing the number of additional operations, with 19 patients benefiting from immediate intervention in this study. The authors believe that the number of second operations prevented and the high BCT rates justify performing FSA. Ductal carcinoma in situ is more difficult to identify in FSA. Preoperative discussions with the patient should reflect these findings.
