SAVI SCOUT® localization of metastatic axillary lymph node prior to neoadjuvant chemotherapy for targeted axillary dissection: a pilot study.

Purpose: In clinically node-positive breast cancer, axillary staging after neoadjuvant chemotherapy (NAC) is optimized with targeted axillary dissection (TAD), which includes removal of the biopsy-proven metastatic lymph node (LN) in addition to sentinel lymph nodes (SLN). Localization of the clipped node is currently performed post-NAC; however, technical limitations can make detection and localization of the treated LN challenging. We prospectively evaluated the feasibility of localizing the metastatic LN with a SAVI SCOUT® reflector (SAVI) prior to NAC for targeted removal at surgery.

A comparison of two non-radioactive alternatives to wire for the localization of non-palpable breast cancers.

Purpose: Multiple wire-free technologies for localization of non-palpable breast cancers have emerged as satisfactory alternatives to wire. However, no study has compared two non-radioactive wire-free approaches to one another. The purpose of this study was to compare outcomes among LOCalizer™ radiofrequency identification (RFID), SAVI Scout® (SAVI), and wire localization (WL).

Microchipping the breast: an effective new technology for localizing non-palpable breast lesions for surgery.

Purpose: Use of a wire to localize a non-palpable breast lesion for surgery is standard but archaic. We sought to evaluate a new radiofrequency localization system (RFLS) as an effective, non-radioactive alternative to the wire.

Methods: Patients who required surgical excision of a non-palpable breast lesion were consented for the study.
