| Popis: | Introduction After neoadjuvant chemotherapy (NAC) for clinically node-positive breast cancer (NPBC), targeted axillary dissection (TAD) reduces the false negative rate (FNR) of axillary node sampling. Axillary lymph node dissection (ALND) is indicated if the clipped node cannot be identified. Prior studies have indicated that a sentinel lymph node harvest (SLNH) of ≥3 also leads to low FNR. We investigated the performance of SLNH thresholds at inferring the status of the axilla during TAD. Methods Retrospective review of the Legacy Health System Tumor Registry was performed. We identified NPBC patients between 2011 and 2016 managed with NAC and TAD. Results In 29 patients, the FNR of the SLNB component of TAD was 11% with SLNH of ≥3; with SLNH of ≤2 nodes the FNR was 20%. Conclusions In patients with NPBC receiving NAC, adequate SLNH is associated with acceptably low FNR. The decision to pursue ALND for clip identification should be made on a case-by-case basis. |
