Audit of Targeted Sentinel Node Biopsy (TSNB) in Patients With Limited Nodal Disease Undergoing Primary Surgery

Targeted Sentinel Node Biopsy will be performed according to routine local practice. The procedure has been standardised for the post-NACT setting as part of the ongoing ATNEC trial. Sites are advised to follow the ATNEC protocol in the primary surgery setting, using either a dual- or single-tracer sentinel node biopsy technique, with localisation and removal of the marked biopsy proven positive node, and removal of at least 3 nodes.
