Abstract
PURPOSE: To determine the efficacy of ultrasound (US)-guided excision of nonpalpable breast cancer and compare it to standard wire-guided breast-conserving surgery (BCS). METHODS: One hundred fifty-eight women with nonpalpable breast cancer who underwent BCS were retrospectively studied. Positive surgical margins and reexcision rates were investigated. RESULTS: Of the total cohort, 68 patients were treated with wire-guided and 90 with US-guided tumor excision. The tumor and patient characteristics were similar in the 2 groups; 13.2% and 12.2% of patients in the wire-guided and US-guided groups, respectively, had positive margins. Patient age, menopausal status, tumor size, histologic type, and histologic grade were associated with increased risk of positive margins. The shave margins were reexcised at the time of original operation more often by wire-guided localization (26.5%) than in the US-guided group (10.0%) (P = .010). The surgeon was able to identify correctly the problematic margin in 100% via intraoperative US and in only 27.8% when the wire-guided surgery was used (P < .001). The reexcision rate by a second operation was similar in 2 groups (P = .798). Eight (11.8%) of 68 patients in the wire-guided group and 9 (10.0%) of 90 patients in the US-guided underwent a second operation. CONCLUSION: US-guided BCS is as effective and safe as standard wire-guided excision of nonpalpable breast tumors.
