“…The study design of the included studies was prevalently prospective (18, 66,7%), involving from 4 to 320 patients each. The devices used in the studies were: SAVI SCOUT (9, 33.3%) [ [32] , [33] , [34] , [35] , [36] , [37] , [38] , [39] , [40] , [41] ], Magseed (10, 37%) [ 38 , [42] , [43] , [44] , [45] , [46] , [47] , [48] , [49] , [50] ], Localizer (5, 18.5%) [ 38 , 40 , [51] , [52] , [53] , [54] , [55] ] and MaMaLoc (1, 3.7%) [ 56 ]. One study reported results about the use of both Magseed and LOCalizer [ 38 ] and in one both SAVI SCOUT and LOCalizer were used [ 40 ].…”

“…Magseed is based on the detection of a ferromagnetic seed by a proprietary handheld magnetometer called Sentimag which was originally developed for sentinel lymph node and occult breast lesion localisation in the MagSNOLL trial [ 32 , 33 ]. For the purpose of occult breast lesion localisation, a 5 mm seed is implanted using an 18 G introducer.…”

Wire-guided localisation (WGL) has been the gold-standard for localising non-palpable breast lesions before excision. Due to its drawbacks, various wireless alternatives have been developed, including LOCalizer™, which is based on radio-frequency identification (RFID) technology. In this systematic review, we consulted EMBASE, Medline and PubMed databases using appropriate search terms regarding the use of RFID technology in the localisation of occult breast lesions. Retrospective and prospective studies were included if they quoted the number of patients, rate of successful placement, retrieval rate, margin positivity rate and the re-excision rate. In addition, studies comparing RFID to WGL were also included and analysed separately. Seven studies were included in this systematic review spanning 1151 patients and 1344 tags. The pooled deployment rate was 99.1% and retrieval rate was 100%. Re-excision rate was 13.9%. One complication was identified. Two studies compared RFID with WGL (128 vs. 282 patients respectively). For both techniques the re-excision rate was 15.6% (20/128 vs. 44/282 respectively, p value is 0.995). Based on our review, LOCalizer™ is safe and non-inferior to WGL in terms of successful localisation and re-excision rates. However, further research is required to assess the cost effectiveness of this approach and its impact on the aesthetic outcome compared with WGL and other wire free technologies to better inform decision making in service planning and provision.

“…These techniques also utilise the gamma probe which is routinely available for sentinel lymph node biopsies, therefore avoiding purchase of additional equipment. However, radioactive localisation techniques are limited by the availability of nuclear medicine services, which may preclude regional/rural centres and are under strict government regulations, 6,8,13–17 which can be cumbersome and prescriptive.…”

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.
