“…We then proceeded to screen the full texts, when available, for the 21 abstracts which initially met the criteria for analysing Magseed localisation efficacy (9,(11)(12)(13)(14)(15)(16)(17)(18)(19)(20)(21)(22)(23)(24)(25)(26)(27)(28)(29)(30). Five studies were excluded from the localisation/identification rate calculation because these data was not provided or were unclear (12,15,21) or because the total number of Magseeds used was unclear (13,22). Hence, 16 studies were used to calculate the rates of successful localisation and placement in the pooled analysis (9,11,14,(16)(17)(18)(19)(20)(23)(24)(25)(26)(27)(28)(29)(30).…”

“…Two publications focused specifically on clinician satisfaction and patient anxiety outcomes for Magseeds compared to WGL (13,21). A prospective interim analysis evaluating clinical outcome and clinician satisfaction with Magseeds compared to WGL reported statistically significant and favourable outcomes for Magseeds: 84.9% of clinicians found Magseeds to be easy/very easy to localise as opposed to 64.5% for WGL.…”

“…However, a separate analysis of patient anxiety related to Magseeds and WGL used standardised state trait anxiety questionnaires to investigate any patterns of the association between localisation method and subsequent patient anxiety (21). Although significance values were not calculated, scalebased average scores were 36 for Magseeds and 41 for WGL, suggesting lower pre-operative anxiety when patients were faced with the Magseed as their localisation technique.…”

Background/Aim: Wire-guided localisation (WGL) remains the most widely used technique for the localisation of non-palpable breast lesions; however, recent technological advances have resulted in non-wire, non-radioactive alternatives, such as magnetic seeds (Magseeds). The aim of this pooled analysis was to determine whether Magseeds are an effective tool for localising non-palpable breast lesions. Materials and Methods: Various databases were searched for publications which reported data on the localisation and placement rates of Magseed. Data on re-excision rates under use of Magseed and WGL were also collected. Results: Sixteen studies, spanning the insertion of 1,559 Magseeds, were analysed. The pooled analysis showed a successful placement rate of 94.42% and a successful localisation rate of 99.86%. Four studies were analysed in a separate pooled analysis and showed no statistically significant difference between reexcision rates using Magseeds and WGL. Conclusion: The use of Magseeds is an effective, non-inferior alternative to WGL that overcomes many of the limitations of the latter. The pre-operative localisation of non-palpable breast cancer traditionally employs wire-guided localisation (WGL) (1). However, several limitations are associated with WGL. The localisation wire can cause manifold complications, such as diathermy burns, pericardial injury and wire dislocation/ transection (2, 3). Furthermore, wire migration and surgical difficulties in accurately assessing the position of the wire tip intraoperatively can pose significant difficulty for the operating surgeon (4). WGL is performed on the day of surgery, and interdepartmental coordination with radiology for localisation in addition to everyday scheduling difficulties may lead to a prolonged surgical waiting time. An underreported limitation of the flexible wire used in WGL is that it increases the risk of needle-stick injury for the surgeon and the pathologist. Furthermore, it protrudes from the breast and is uncomfortable for the patient. The prospect of an additional procedure on the day of major breast surgery can also be very stressful for patients in whom anxiety level is already high (2). Widespread use of screening methods has led to an increased incidence of non-palpable breast cancer. It is therefore imperative that localisation methods with high patient, radiologist and surgical satisfaction rates are developed. Radioactive seed localisation (RSL) is a feasible alternative to WGL. RSL can occur up to 5 days prior to the surgery and the seeds can be accurately detected with a hand-held gamma probe (5). Furthermore, recent evidence suggests that RSL would be more cost-effective than WGL (6) and would improve the oncological outcomes of imageguided surgery (7). However, handling of radioactive material requires special licensing and is associated with strict regulatory requirements. Hence, the optimal solution would be a non-wire non-radioactive localisation method which contains no energy source. This has led to the emergence of Savi Sco...

“…Magseed technology is an evolving localisation strategy for impalpable breast lesions, with possible advantages over other localisation techniques, including the decoupling of radiology and theatre, flexibility in incision placement and improved patient experience 13,18 . Thus, magnetic technology may have the advantages of radioactive seeds without the radiation safety issues.…”

Background Magseed technology is a recently introduced localisation technique for impalpable breast lesions with possible advantages over traditional techniques. These include improved theatre logistics, flexibility in incision placement and improved patient experience. This multicentre study evaluates the experience of introducing Magseed technology into routine surgical practice. Methods A prospective multicentre study of Magseed localised procedures was performed. Insertion data were recorded by the radiologist including lesion characteristics and Magseed insertion accuracy. The surgical team recorded time from insertion to operation, operating time and surgical satisfaction. Pathology results were reviewed for specimen weight and margins. Results Between February 2019 and June 2020, 100 patients were enrolled. Magseed localised procedures included 18 excisional biopsies, 23 wide local excisions (WLE), 50 WLE with axillary surgery and four cases of Magseed localised breast WLE with Magseed localised axillary surgery. There were three therapeutic mammoplasties and two cases of Magseed localised targeted axillary node dissection alone. A total of 90% of Magseeds were radiologically placed within 5 mm of the target lesion/node. Time between incision and specimen removal was 17 min (range 6–40 min). All breast and axillary Magseeds were successfully identified and retrieved during surgery. The target lesion was identified in the specimen in all cases. A total of 10% of cases required further surgery for pathologically positive margins. Overall, surgeons reported that Magseed localisation was “easy” or “very easy” in 77% of cases. Conclusion Magseed is a reliable, safe and accurate surgical technique that provides logistical advantages and flexibility of surgical approach. The method was well‐accepted by all users.

Image-guided Localization Techniques for Nonpalpable Breast Lesions: An Opportunity for Multidisciplinary Patient-centered Care

Selection of a localization method for nonpalpable breast lesions offers an opportunity for institutions to seek multidisciplinary input to promote value-based, patient-centered care. The diverse range of nonpalpable breast and axillary pathologies identified through increased utilization of screening mammography often necessitates image-guided preoperative localization for accurate lesion identification and excision. Preoperative localization techniques for breast and axillary lesions have evolved to include both wire and nonwire methods, the latter of which include radioactive seeds, radar reflectors, magnetic seeds, and radiofrequency identification tag localizers. There are no statistically significant differences in surgical outcomes when comparing wire and nonwire localization devices. Factors to consider during selection and adoption of image-guided localization systems include physician preference and ease of use, workflow efficiency, and patient satisfaction.
