Pre-operative localization of impalpable breast lesions using iodine 125 seeds: Placement accuracy and multidisciplinary challenges

Research output: Contribution to journalArticle

Abstract

Introduction: The number of impalpable breast lesions requiring pre-operative lesion localization (PLL) continues to increase. The use of Radio-guided Occult Lesion Localization with Iodine 125 Seeds (ROLLIS) offers multiple benefits for the multidisciplinary team (MDT), but is not without challenges. Aims: The aims of this audit were to review our multidisciplinary team's experience following introduction of ROLLIS as standard of care for PLL, identify challenges and evaluate seed placement accuracy (SPA). Results/outcomes: Over a nineteen month period, 327 seeds were inserted: 96% of single seed localizations were within 10 mm, 91% within 5 mm and 42% within or in contact with the lesion (or marker clip surrogate) on post-insertion two view mammography. Each component of the MDT reported on benefits of the ROLLIS program and challenges faced. Examples included: an undetectable seed in the operating room, a seed damaged in pathology during specimen processing, suboptimal seed position requiring hook-wire localization (HWL) and delayed seed removal in a patient who initially refused to return for surgery. Conclusion: ROLLIS results in high seed placement accuracy. Despite clear advantages, use of ROLLIS presents some multidisciplinary challenges. Robust patient information, training of new staff and adherence to strict policies and protocols are required to ensure safe delivery of a ROLLIS program.
