Intraoperative ultrasound localization to guide surgical excision of nonpalpable breast carcinoma.

摘要: Abstract Background: This report describes a technique of intraoperative tumor localization by ultrasound without the use needle or wire to guide excision nonpalpable breast cancers. The results our experience with pathologic margin status are reviewed. Study Design: From 1994 1998, 65 cancers in 62 patients biopsy-proved cancer were excised using localization. margins from initial surgical specimen and any further excisions, either at first operation later procedures, was recorded. distance closest also determined. Results: overall success achieving pathologically negative 97% (63 cancers). Three underwent second operative procedure, two for positive one less than 1 mm (second operation=4.8% patients). After completion mean 0.8 cm. Conclusions: Intraoperative is feasible gives results, terms margins, that comparable those achieved standard needle-wire-guided excisions.
