Abstract

Background and Objectives: Complete excision of a nonpalpable breast cancer after wire localization is a difficult procedure. Often, adequate margins are not obtained, and a second procedure is then required. Prospectively, we studied the feasibility of ultrasound-guided excisions of nonpalpable breast cancers, with particular attention to the accuracy of the procedure in obtaining adequate margins. Methods: Prospectively, 19 patients with 20 mammographically detected nonpalpable, highly suspect, breast tumors were entered in this feasibility study. In 15 of these, the diagnosis of invasive malignancy was established preoperatively. All patients underwent ultrasound-guided excision with the intent to obtain adequate margins. We also reviewed our own experience with the excision of nonpalpable breast cancers after wire localization. Results: Of the 20 excisions with ultrasound guidance, there were 19 carcinomas and 1 ductal carcinoma in situ. Of the 19 carcinomas, 17 (89%) were excised with adequate margins. Of the 43 carcinomas that were excised after wire localization, only 17 (40%) had been resected with adequate margins. Conclusions: Ultrasound-guided excision appears to be a reliable procedure for obtaining adequate margins in the resection of nonpalpable breast cancers. Other advantages of this procedure are increased patient comfort and decrease in operating room time.
