Would you go back and do an axillary lymph node dissection if a sentinel lymph node biopsy showed a single lymph node with extracapsular extension?

For microscopic ECE, would manage with comprehensive RNI but if gross ECE, would favor dissection and then RT.

I would agree that omission of axillary dissection for pathologic extranodal extension on sentinel node biopsy for a clinically negative axilla is appropriate based on the Z11 trial. Patients with gross extranodal extension (ie. matted lymph nodes) were excluded from the study but microscopic extran...

AMAROS and OTOASOR both allowed microscopic ECE - so that is not an indication to exclude patients from axillary RT and subject these patients to the morbidity of AND.
