Selective lymph node dissection

ACOSOG Z0011 trial 0  (stages I and II) in patients who undergo breast conservation therapy, axillary lymph node dissection does not improve locoregional control or survival.

This trial has demonstrated the safety of limiting axillary surgery to the SLNB without performing formal axillary dissection for sentinel node positivity.

This  avoids of the  morbidity of the axillary dissection.

If node is  positive the patient should receive adjuvant chemotherapy and radiation therapy.
