BACKGROUND: The regional lymph node control and survival impact of axillary dissection in breast cancer has been the subject of multiple randomized trials, with various results. This study reviews and conducts a meta-analysis of contemporary trials of axillary dissection in patients with early stage breast cancer. METHODS: A systematic MEDLINE review identified 3 randomized trials published between January 2000 and January 2007 of axillary dissection versus no dissection in clinically lymph node negative early stage breast cancer patients. A fourth trial of axillary radiotherapy versus no axillary treatment was also identified and included in this review, Meta-analyses were performed for survival, axillary recurrence, metastatic disease, and ipsilateral breast recurrence. RESULTS: All trials reported a higher rate of axillary recurrence (1.5%-3%, median follow-up 5-15 years) in the absence of axillary dissection or radiotherapy. Overall survival was similar with and without definitive axillary treatment in 3 of the 4 trials, with an increased rate of non-breast cancer-related death in the observation arm of the fourth trial. Meta-analyses found no significant difference in overall survival (odds ratio [OR] 1.55; 95% confidence interval [0], 0.74-3.24), metastases (OR 0.91; 95% Cl, 0.65-1.29), or ipsilateral breast recurrence (OR 1.11; 95% Cl, 0.68-1.83) associated with axillary treatment. A significantly lower rate of axillary recurrence was seen after lymphadenectomy (OR 0.28; 95% Cl. 0.11-0.73, P
