In this situation, a full axillary lymph node dissection, removing more than 10 lymph nodes from the arm pit, is unnecessarily extensive in about half of the patients. More extensive surgery leads to a risk for arm lymphedema and functional problems with the arm and shoulder region, which should be avoided if not beneficial for diagnosis or prognosis. This trial seeks to ascertain that less extensive surgery, performed by only removing the first lymph node\u002Fs in the armpit (the sentinel lymph node\u002Fs) and the known metastatic lymph nodes (targeted axillary dissection, TAD), offers non-inferior survival outcomes to a full axillary lymph node dissection.",[58,59,60],"Breast Carcinoma","Breast Cancer","Breast Surgery",[62,63,64,65,66],"axillary metastases","axillary lymph node dissection","targeted axillary dissection","sentinel lymph node biopsy","axillary ultrasonography","NOT_YET_RECRUITING","2025-11-27",{"date":70,"type":71},"2025-12-05","ACTUAL",{"date":73,"type":52},"2026-01-01",{"date":75,"type":52},"2040-12-31",{"name":5,"class":6}]
