Biopsy of sentinel nodes can predict the presence or absence of axillary-node metastases in patients with breast cancer. However, the procedure can be technically challenging, and the success rate varies according to the surgeon and the characteristics of the patient.

SummaryBackground-Sentinel node surgery was designed to minimize side effects of lymph node surgery but still offer outcomes equivalent to axillary dissection. The aims of NSABP Protocol B-32 were to determine whether sentinel node resection in breast cancer patients achieves the same survival and regional control as axillary dissection but with fewer side effects.
