KK Women's and Children's Hospital150 enrolled

Overview

The investigators aimed to determine if axillary ultrasound can reliably distinguish between patients with limited or high nodal burden, so that the patients with limited nodal burden can potentially avoid chemotherapy and instead receive upfront surgery followed by gene assay testing.
