A 10-year outcome study was performed in 517 women (mean age, 52.6 years [range, 30 years-65 years]) with T1N0 breast cancer who were treated with conservative surgery and prospectively randomized to either axillary lymph node dissection or observation. Adjuvant treatment was based on biological factors of the primary tumor in the group of patients who received no axillary surgery. Overall survival and disease-free survival did not appear to differ significantly between treatment arms, thereby indicating that axillary surgery may be avoided in these patients.
