RESUMO

BACKGROUND: Currently, there are broadly differing patterns in the management of the axilla after neoadjuvant chemotherapy (NAC) and no consensus with clinically strong evidence on the subject. A survey was performed to assess the current axillary management after NAC among Brazilian breast cancer surgeons. METHODS: The Brazilian Society of Mastology members were invited by email to complete an anonymous online survey and a total of 426 responses were collected. RESULTS: The majority of responders (67%) indicated performing routine axillary staging by physical exam, ultrasound, and fine needle biopsy in case of a suspicious node before NAC. Among breast surgeons working in the Brazilian Public Unified Health System, 11.3% answered that sentinel lymph node biopsy (SLNB) is not reasonable after NAC in their services. Seventy-seven responders (18.2%) reported performing SLNB instead of axillary lymph node dissection (ALND) only in patients who are clinically node-negative before NAC. Axillary complete pathologic response is necessary to omit ALND for 42.8% of responders. The molecular profile of a breast tumor is not considered when choosing axillary management after NAC for 73.7% of responders. CONCLUSIONS: Our survey highlighted the trend towards de-escalation of axillary surgery and observed high heterogeneity in axillary management after chemotherapy in a group of brazilian breast surgeons.
