Official title
Selective Use of ALND in N1 HR+/HER2- Breast Cancer Patients With 1 or 2 Positive Sentinel Lymph Nodes Undergoing Upfront Breast Surgery and Adjuvant Radiation: A Prospective Study
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The purpose of this study is to find out how often the researchers can avoid an ALND in patients with early-stage, node-positive HR+/HER2- breast cancer who are having upfront surgery. The study researchers think that, if AUS before surgery can help identify people who may have up to 3 affected lymph nodes, it will be possible to perform the less radical standard SLNB during surgery.
