Cancers, Vol. 16, Pages 1345: Evaluating Radar Reflector Localisation in Targeted Axillary Dissection in Patients Undergoing Neoadjuvant Systemic Therapy for Node-Positive Early Breast Cancer: A Systematic Review and Pooled Analysis Cancers doi: 10.3390/cancers16071345 Authors: Umar Wazir Michael J. Michell Munaser Alamoodi Kefah Mokbel SAVI SCOUT® or radar reflector localisation (RRL) has proven accurate in localising non-palpable breast and axillary lesions, with minimal interference with MRI. Targeted axillary dissection (TAD), combining marked lymph node biopsy (MLNB) and sentinel lymph node biopsy (SLNB), is becoming a standard post-neoadjuvant systemic therapy (NST) for node-positive early breast cancer. Compared to SLNB alone, TAD reduces the false negative rate (FNR) to below 6%, enabling safer axillary surgery de-escalation. This systematic review evaluates RRL’s performance during TAD, assessing localisation and retrieval rates, the concordance between MLNB and SLNB, and the pathological complete response (pCR) in clinically node-positive patients post-NST. Four studies (252 TAD procedures) met the inclusion criteria, with a 99.6% (95% confidence [CI]: 98.9–100) successful localisation rate, 100% retrieval rate, and 81% (95% CI: 76–86) concordance rate between SLNB and MLNB. The average duration from RRL deployment to surgery was 52 days (range:1–202). pCR was observed in 42% (95% CI: ...
