## Relevancia
Conferencia internacional de consenso bianual; punto de referencia mundial para la toma de decisiones en cancer de mama temprano. El panel multidisciplinar vota sobre escenarios clinicos clave, incluyendo des-escalada quirurgica axilar post-NAC en pacientes cN+ que convierten a ypN0.

## Recomendaciones clave (resumen)
- Acepta BSGC post-NAC en pacientes cN+ que convierten a cN0 si se cumplen estandares de calidad (>=3 ganglios, doble trazador, marcaje del ganglio biopsiado).
- Tendencia consistente a des-escalada quirurgica axilar en respondedoras.
- Recomienda evaluacion clinica/ecografica axilar post-NAC antes de la cirugia.
- TAD (Targeted Axillary Dissection) reconocida como tecnica aceptable para reducir tasa de falsos negativos.

## Abstract
This year, the St. Gallen Consensus Conference on early breast cancer treatment standards took place for the third time in Vienna, Austria, which is where the next conference will also take place (next date: March 17-20, 2021!). Once again, more than 3,000 participants from over 100 countries came together, and, overall, the 2019 St. Gallen/Vienna conference was a great success. After 3 days of reviews conducted by a global faculty concerning the most important evidence published in the last 2 years, the Consensus votes' challenge was to define the impact on routine everyday practice. This year, the conference's main theme was the optimization of early breast cancer therapies by assessment of the magnitude of benefit, aiming at further refinement when compared to de-escalation and escalation, which were mainly the topic of the 2017 conference. Patient empowerment and the importance of shared decision-making were particularly emphasized. The traditional panel votes were moderated by Eric Winer from Harvard, and for the most part, they managed to clarify most of the critical questions. This brief report by Editors ofsummarizes the results of the 2019 international panel votes with respect to locoregional and systemic treatment as a quick news update for our readers, but it expressly does not intend to replace the official St. Gallen Consensus publication that will follow shortly in.
