A pioneer Australian case of Savi-Scout™ assisted resection for breast cancer recurrence

Abstract

Abstract This case describes a 48-year-old female who the first patient in Australia treated surgically with Savi-Scout™ assisted breast cancer localization, utilizing electromagnetic wave signalling for accurate depth guidance. After initial breast cancer diagnosis at age 44 treated with bilateral mastectomies and DIEP flap reconstructions, clinical surveillance found recurrent right chest wall disease. US and MRI identified a 4–6 mm interpectoral lesion; poorly differentiated metastatic micropapillary carcinoma on core biopsy. Savi-Scout™ was selected to assist localization and removal of the lesion due it’s technically challenging location. Informed consent was gained and one month pre-operatively a 12× 1.6 mm electromagnetic wave Savi-Scout™ reflector was inserted via US-guidance. A Savi-Scout™ probe guided marking, incision and dissection of subcutaneous tissues and pectoralis muscles, through localization to the reflector. The lesion and reflection were excised and confirmed on specimen radiograph, with clear histopathology margins. This technology has potential applications for challenging breast cancer cases.
