Study design: international web-survey

Brief presentation: Breast cancer management was considerably modified during the COVID-19 pandemic. This was the first, fastest, and largest survey among breast specialists investigating this topic and showing a snapshot on the international discrepancies. In ten days, 377 breast units from 41 countries adhered and responded our questionnaire.

EUBREAST 08 (R) International Survey on lymph node management in node positive breast cancer patients after neoadjuvant chemotherapy

Topic:International discrepancies on the axillary management amongradiation oncologists and breast surgeons

Study design: international web-survey

Brief presentation: There is no consensus on the axillary management following primary systemic treatment in clinically node-positive breast cancer patients. The discrepancies in the breast surgical and radiation therapy approaches have been «quantified» testing a representative sample of 349 breast surgeons and radiation oncologists from 45 countries. The resulted heterogeneity among countries and centres, reinforces the rationale of the ongoing AXSANA (EUBREAST-3) study.
