Overview
Brief Summary
This clinical trial aimed to confirm the effectiveness of sentinel lymph node surgery by determining the lymph node identification rate using multimodal sentinel lymph node marker methods in patients with advanced breast cancer undergoing neoadjuvant chemotherapy (NAC).
Detailed Description
After NAC, the sentinel lymph node (SLN) identification rate is lower, and it has a higher false-negative rate than that in early-stage breast cancer. As appropriate SLN surgery directly affects the treatment and prognosis of patients undergoing NAC, evaluation to identify SLN using various methods is necessary. This clinical trial aimed to confirm the effectiveness of sentinel lymph node surgery by determining the lymph node identification rate using multimodal sentinel lymph node marker methods in patients with advanced breast cancer undergoing neoadjuvant chemotherapy (NAC).
