Purpose Non-Radioactive seed localisation (NRSL) is a highly feasible alternative to hookwire-guided localisation (HWL) for breast lesion excisions. Much data is published in international literature, however Australasian studies are scarce. We present single-institution analysis with scoping review of the Australasian literature to inform clinicians on use and efficacy of NRSL. Methodology A retrospective study was undertaken at a single institution for patients that underwent breast surgery using Magseed and/or Magtrace technologies from inception through to Dec 2023. Primary outcome was the rate of successful excision of lesion, secondary outcomes was the placement and removal of Magseed, operation time and complications. A scoping review was concurrently undertaken. Results 14 patients were included in our study. All underwent Magseed insertion with no reports of seed migration prior to operation. No radiological adverse events occurred. Magseed were removed in 100% of cases with average clear margins of >2mm. Two cases required re-excision and there were no Magseed related complications. Magtrace was utilised in 6 cases, reporting 100% clearance of sentinel nodes that have taken up Magtrace, Scoping review identified four studies in the Australasian literature involving 310 patients. Two studies were retrospective and two were prospective, all outlined advantages of Magseed use with general consensus reporting a lower re-excision rate (20%) in comparison to HWL (26%). Conclusion Limited research exists in the Australasian literature for the use of NRSL. Our study data is generally in agreement with the published literature, purporting the safe, efficacy and preferable use of Magseed for breast lesion excisions.
