Current axillary management of patients with early breast cancer and low volume nodal disease undergoing primary surgery: Results of a United Kingdom national practice survey

Purpose:
UK NICE guidelines recommend axillary node clearance (ANC) should be performed in all patients with biopsy-proven node positive breast cancer having primary surgery. There is however increasing evidence such extensive surgery may not always be necessary. Targeted axillary dissection (TAD) may be an effective alternative in patients with low volume nodal disease who are clinically node negative (cN0) but have abnormal nodes detected radiologically. This survey aimed to explore current management of this group to inform feasibility of a future trial.

Methods:
An online survey was developed to explore current UK management of patients with low volume axillary disease and attitudes to a future trial. The survey was distributed via breast surgery professional associations and social media from September-November 2022. One survey was completed per unit and simple descriptive statistics used to summarize the results.

Results:
51 UK breast units completed the survey of whom 78.5% (n=40) reported performing ANC for all patients with biopsy-proven axillary nodal disease having primary surgery. Only 15.7% of units currently performed TAD either routinely (n=6, 11.8%) or selectively (n=2, 3.9%). There was significant uncertainty (83.7%, n=36/43) about the optimal surgical management of these patients. Two-thirds (n=27/42) of units felt an RCT comparing TAD and ANC would be feasible.

Conclusions:
ANC remains standard of care for patients with low-volume node positive breast cancer having primary surgery in the UK, but considerable uncertainty exists regarding optimal management of this group. This survey suggests an RCT comparing the outcomes of TAD and ANC may be feasible.
