Kim WH, et al. - Researchers here aimed to review their experience with ultrasound (US)-guided localization of axillary lymph nodes using activated charcoal for the guidance of axillary surgery after neoadjuvant chemotherapy (NAC) in clinically node-positive breast cancer patients. At restaging after NAC in clinically node-positive breast cancer patients, they recognized this technique as a useful technique to guide axillary surgery, with a high identification rate.
