Resumen
Neoadjuvant therapy, which reduces advanced breast tumours before surgery, is common in medical practice. However, accurately mapping lymph nodes post-therapy is challenging and affects staging accuracy. One solution is marking the affected lymph nodes in the armpit before therapy, then removing the marked nodes during surgery via targeted axillary dissection (TAD), which combines standard sentinel lymph node biopsy (SLNB) with pre-neoadjuvant marked lymph node biopsy (MLNB). Radar reflector localisation (RRL) is a promising technology for locating tumours. Our study found that using RRL in TAD is reliable and accurate. This reduces the need for extensive armpit surgery in responsive patients, minimising surgical complications and improving their quality of life without compromising cancer outcomes.
