[Breast cancer and axillary area: state of the art and perspectives]. / Cancer du sein et creux axillaire : état de l'art et perspectives.

A therapeutic surgical de-escalation has been observed since many years with an actual prolongation for axillary lymph node area treatment. Axillary lymph node dissection (ALND) omission has been studied before and after validation of sentinel node (SN) biopsy procedure. A non-inferiority of ALND omission has been reported in case of non-involved SN. ALND omission has been studied in case of SN involvement without consensus in relation with scientific level of proof and with selective indications. The purpose of this work is to make a synthesis of the experiences on this subject then to envisage the current and future perspectives.
