Summary
The SAVI SCOUT® system offers effective wireless localisation for nonpalpable breast lesions, demonstrating high success rates in reflector placement, localisation, and retrieval. This method provides a reliable alternative to wire localisation for breast lesion excision.
Area of Science:
- Oncology
- Radiology
- Surgical Oncology
Background:
- Wire localisation is a standard technique for nonpalpable breast lesions.
- Logistical challenges associated with wire localisation have driven the adoption of wireless alternatives.
- The SAVI SCOUT® system represents a wireless solution for breast lesion localisation.
Purpose of the Study:
- To evaluate the efficacy and reliability of the SAVI SCOUT® system for wireless localisation of nonpalpable breast lesions.
- To assess key outcomes including reflector placement, intraoperative localisation, and margin status.
- To compare SCOUT®-guided excision with traditional wire localisation methods.
Main Methods:
- Retrospective analysis of patients undergoing SCOUT®-guided excision of nonpalpable breast lesions.
- Data collected from February 2024 to June 2025 across a tertiary institution and private practice.
- Primary outcomes: successful reflector placement, intraoperative localisation, reflector retrieval, and positive margin rates.
Main Results:
- 170 lesions excised from 163 patients; 24 post-neoadjuvant chemotherapy (NACT).
- High success rates: 97% reflector placement, 98% intraoperative localisation, 100% reflector retrieval.
- Margin involvement and re-excision rates were 9% and 19%, respectively; 8.2% post-operative complications.
Conclusions:
- The SAVI SCOUT® system is an effective and reliable wireless method for nonpalpable breast lesion excision.
- It overcomes limitations of wire localisation, offering high procedural success.
- This technology supports accurate and efficient surgical planning and execution.
