Abstract
- PURPOSE
Absorbable retaining thread (ART) needle localization utilizes a guiding needle with a thread; this technique was invented to reduce patient discomfort and wire migration. We investigated the feasibility of ultrasound (US)-guided ART needle localization for nonpalpable breast lesions.
METHODS
ART needle localization was performed for 26 nonpalpable breast lesions in 26 patients who were scheduled to undergo surgical excision the day after localization. Seventeen breast lesions were initially diagnosed as invasive ductal carcinoma, six as ductal carcinomas in situ, and one as fibrocystic change. The other two cases without an initial pathologic diagnosis had suspicious US features, and excision was planned concomitantly with contralateral breast cancer surgery. The primary outcome was the technical success rate of ART needle localization confirmed by US immediately after the procedure, and the secondary outcomes were the percentage of clear margins on pathology and the complication rate of ART needle localization.
RESULTS
The technical success rate of ART needle localization was 96.2% (25 of 26 patients), and the ART was located 1 cm away from the mass in one patient (3.8%). The lesions were successfully removed with clear margins in all 26 patients. No significant complications related to ART needle localization were observed.
CONCLUSION
ART needle localization can be an alternative to wire needle localization for nonpalpable breast lesions.
