L’exploration axillaire en pratique quotidienne dans le parcours diagnostique d’un cancer du sein

When a breast cancer is diagnosed, the quality of the evaluation before treatment is essential to guide the therapeutic decision. The staging axillary is necessary because it estimates the regional extension of the disease, which makes it a paramount prognosis factor. Some different pre-operative medical imaging can reveal metastasis axillary nodes. However, the axillary ultrasound remains the reference imaging and it also leads the biopsies too. Since the ACOSOG-Z0011 trial, we are facing a therapeutic de-escalation in the axillary surgery. According to recent results, we can note that the position of the axillary imaging is more and more important. The purpose of the ultrasound is to avoid a two-stage dissection after a positive sentinel lymph node when the ACOSOG-Z0011 criteria are not met.
