NSABP B-32 confirming the safety of SNB in clinically node negative breast cancer

ASCO 2010:
This abstract is the 8 year follow up of the NSABP B-32 trial, which compared SNB (sentinel node biopsy) alone vs axillary dissection in clinically node negative patients. 5,611 patients were randomized in this trial, with the power to detect a 2% difference in DFS at 5 years. Thankfully for current practice, there was no difference between the two groups.

Primary outcome results of NSABP B-32, a randomized phase III clinical trial to compare sentinel node resection (SNR) to conventional axillary dissection (AD) in clinically node-negative breast cancer patients.
