RT Journal Article SR Electronic A1 Nichols, Emma Hitt T1 Sentinel Lymph Node Biopsy before or after Neoadjuvant Chemotherapy: Final Results from the SENTINA Trial JF MD Conference Express YR 2013 FD SAGE Publications VO 12 IS 20 SP 14 OP 14 DO 10.1177/155989771220011 UL http://mdc.sagepub.com/content/12/20/14.1.abstract AB For patients with breast cancer who undergo primary surgery, sentinel lymph node biopsy (SLNB) is the standard staging procedure to determine the axillary status when the patient is clinically node negative [D'Angelo-Donovan DD et al. Surg Oncol 2012]. However, for patients who undergo neoadjuvant chemotherapy, the optimal role and timing of SLNB is still unclear. This article presents final results from the prospective German, multi-institutional Sentinel Neoadjuvant [SENTINA] trial.
