One-year morbidity after sentinel node biopsy and breast surgery

Abstract

Posttreatment morbidity within 1 year after sentinel node biopsy was evaluated objectively by physical examination and also by evaluating patients self-reports of symptoms in a questionnaire. These patients were compared with patients who underwent axillary clearance. At 2 weeks after surgery patients who had undergone sole sentinel node biopsy had made significantly better recoveries than those who had undergone axillary clearance. Although every fourth patient complained of at least mild arm symptoms 1 year after sole SNB, the risk of severe long-term morbidity is minimal. In particular, the risk of disabling lymphoedema seems to be negligible after SNB only.
