Background. Sentinel lymph node biopsy (SLNB) is a technique that is widely used in the management of early breast cancer. Surgeons are encouraged to validate their initial SLNB results by performing an audit in which both a SLNB and an axillary lymph node dissection (ALND) are performed. For surgeons in solo private practice this is not financially viable as the SLNB would not be paid for by the medical insurance companies. Methods. Forty consenting patients were enrolled in the audit. The initial 5 patients (group A) were entered into a traditional Audit–an ALND and a SLNB. The next 35 patients (group B) formed part of a modified audit–an axillary sample was performed if the sentinel node was negative (group B1) and an ALND if the node was positive (group B2).
