Introduction: Given the high rate of complete nodal response, the role of axillary lymph node dissection on staging the axilla has been questioned. This survey, addressed to breast cancer surgeons in Spain, has the objective of assessing current clinical trends on axillary staging of cN + patients treated with NAC.
Methods: An online survey was conducted among breast surgeons from the Spanish Society of Surgery (AEC), Spanish Surgical Oncology Society (SEOQ), Spanish Breast Cancer Surgeons Society (AECIMA) and Spanish Gynecology and Obstetrics Society (SEGO). It was structured in 5 sections: general information and clinical practice, knowledge of clinical trials, diagnosis work-up and nodal marking, axillary staging, and axillary treatment.
Results: 150 breast cancer surgeons completed the full survey (96.7%). 81.8% of respondents performed SLNB or targeted axillary dissection in cN1 patients treated with NAC. Radiological axillary response was the preferred parameter guiding the surgical strategy. The excision of the clipped node (92.0%), use of dual tracer (73.2%), and axillary US (65.9%) after treatment were the most important variables considered by respondents, to increase the accuracy of SLNB in cN + patients.
Conclusion: This survey confirms a trend toward a less invasive approach for axillary staging in cN + patients treated with NAC among breast cancer surgeons in Spain. While there is widespread agreement in less invasive approaches to axillary staging, there is, however, a lack of consensus around treatment strategy. Further, it shows a wide heterogeneity in their clinical practice. This study highlights the need for clear evidence concerning less invasive staging procedures and their oncological safety, to ensure consistent recommendations in surgical practice.
