Background Breast cancer is the most commonly diagnosed noncutaneous malignancy and remains the second leading cause of cancer deaths in women. The Savi Scout (Cianna Medical, Merit Medical Systems, Inc. South Jordan, UT) is a wireless, nonradioactive, wave reflection implant system that enables surgeons to remove targeted breast lesions. Our study aims to be the largest comparison of wire and Savi Scout localization techniques for positive margin, complication, and reoperation rates. Methods Single-institution retrospective review of 512 patients that had Savi Scout Surgical Guidance System breast lesion biopsy or wire localized breast biopsy from May 2017 to December 2018. A RedCaps database was created and reviewed for outcomes. Results For 320 Savi scout patients, margins were positive or less than 1 mm in 18 cases (5.6%). 17 (5.3%) patients required reoperation. Surgical site occurrence was found in 7 (2.1%) patients, and 2 patients required intervention (0.6%). For 175 wire localization patients, margins were positive or less than 1 mm in 24 patients, and all required reoperation (13.7%). A surgical site occurrence was found in 13 (7.4%) patients and 5 patients required intervention (2.8%). Discussion In our series, the Savi Scout localization system resulted in a lower rate of positive margins, reoperation, and surgical site occurrence. These data suggest that Savi Scout localization is a reasonable replacement to wire localization for breast lesions and might produce superior results.

Wire localized excision (WLE) has been a long-standing method for localization of nonpalpable breast lesions. Disadvantages of this method include difficulty locating the wire tip in relation to borders of the lesion, imprecise placement of the wire, and the need to place the wire shortly before scheduled surgery. These shortcomings may lead to a high positive margin rate requiring re-excision to obtain clear margins for breast cancer. Radioactive seed localized excision (RSLE) of nonpalpable breast lesions has been advocated as a safe and effective alternative to WLE. The primary endpoints of the study were to compare re-excision rates between WLE and RSLE of nonpalpable breast lesions and to determine if there were any differences in volume of tissue removed. One hundred three patients were included in a retrospective review of localized breast excisions done by a single surgeon. Forty-four patients underwent WLE between April 2007 and February 2009. Fifty-nine patients underwent RSLE between September 2009 and January 2012. Margins were considered to be clear if at least 1 mm of normal tissue was obtained from the circumferential periphery of the lesion in question. RSLE resulted in a re-excision rate of 17 versus 55 per cent re-excision rate for wire localization ( P < 0.001). Excision volume was greater for patients having wire localization ( P = 0.074). RSLE is an effective technique for excision of non-palpable breast lesions in the community setting. This technique allows for accurate localization and appears to allow for smaller volume of tissue to be excised.

There have been very few reports of severe complications accompanied by wire localization of breast lesions, such as transsection of the wire and wire migration to the extramammary sites. This is a report of wire migration into the pulmonary hilus demanding surgical removal.

Background: Nonpalpable breast lesions require localization, the gold standard for which is preoperative ultrasound-guided wire localization (PUGWL). Our unit also employs intraoperative ultrasound-guided wire localization (IUGWL). Here we evaluate PUGWL and IUGWL outcomes between 2014 and 2018. Primary outcomes were reoperation rates, complication rates and average specimen weights. Trainee feedback and cost analysis assessed IUGWL viability. Methods: Prospectively recorded data were collected. 511 patients were included (241 PUGWL and 270 IUGWL). Results: Reoperation rates: PUGWL 17.7% versus IUGWL 13.9% (p = 0.28) . Complication rates: PUGWL 5.8% versus IUGWL 6.6% (p = 0.72) . Average specimen weight: PUGWL 34.2 g versus IUGWL 24.3 g (p < 0.0001) . Trainees needed 15 supervised cases to be IUGWL competent. Performing IUGWL saves £289 per localization. Conclusion: IUGWL outcomes are comparable to those of PUGWL. IUGWL is cost-effective, patient-friendly and easy to learn and replicate. IUGWL merits wider dissemination and further planned research.

Purpose. For accurate resection of nonpalpable malignant breast lesions with a tumor-free resection rim, an exact and stable wire localization is essential. We tested the resistance towards traction force of different localization devices used in our clinic for breast lesions in two types of tissue.Materials and Methods. Eight different commercially available hook-wire devices were examined for resistance towards traction force using an analogue spring scale.Results. Most systems showed a high level of movement already under small traction force. Retractable systems with round hooks such as the Bard DuaLok , the Fil d’Ariane, and the RPLN Breast Localization Device withstood less traction force than the other systems. However, the Bard DuaLok system was very resistant towards a small traction force of 50 g when compared to the other systems. The Ultrawire Breast Localization Device withstood the most traction force in softer tissue and Kopans Breast Lesion Localization Needle withstood the most force in harder tissue.Conclusion. The Ultrawire Breast Localization Device and Kopans Breast Lesion Localization Needle withstood the most traction force. In general retractable systems withstand less traction force than nonretractable systems.
