Abstract:
Introduction: Traditionally impalpable breast cancers have been localised with image guided techniques of wire guidance or ultrasound marking. Magseed is a small magnetic seed which is changing practice of localisation of these cancers. The aim of this study was to see if the change of practice of localisation to Magseed affected patient outcome evaluated by re-excision rate, specimen weight and patient satisfaction. Method(s): A change of practice service evaluation was conducted at the Shrewsbury and Telford Hospital of all patients who had imaged guided wide local excision for impalpable breast cancer from July 2017 to August 2019. Data recorded included tumour demographics, localisation method, size of tumour and specimen weight. Evaluation of localisation methods included re-excision rates, type of further surgery, cost saving in reduction in re-excision, and patient satisfaction. Result(s): 2017/2018 226 Traditional guided WLE were performed. 2018/2019 90 traditional guided WLE, and 106 Magseed WLE were performed. Tumour demographics, size of tumour were similar for localisation methods. The introduction of Magseed in our practice has resulted in a significant reduction in overall re-excision rates from 22.4 to 12%, (z =2.6616 p.00782), and average specimen weight from 40 to 27g (t= -3.2364, P.000716). Cost saving analysis of further surgery showed a saving of 34,457 with 48% less further operations following change of practice. 98% of patients had a very good/excellent experience of Magseed. Conclusion(s): Magseed demonstrates a triple effect on patient outcome with significant reduction in re-excision rate, cost saving by reducing further surgery and high patient satisfaction.
