Some 2766 patients with breast cancer and 1-2 positive nodes on sentinel lymph node biopsy were randomly allocated to axillary dissection or no surgery. Adjuvant treatment was similar in both groups. 5-year recurrence free survival was similar: 89.7 per cent in controls and 88.7 per cent in the axillary dissection group.
Comment: Very important trial that questions the need for a procedure that has a number of significant local complications and adverse effects on quality of life, without any evidence for survival benefit.
