Conclusion This study validates the normal tissue sparing effect of proton FLASH when delivered with pencil beam scanning. Full dose response curves for acute skin damage in a mouse leg model were obtained, which enabled the quantification of the normal tissue sparing factor for proton FLASH. A 41-55% higher dose was required to give the same biological response when using FLASH dose rates compared to the conventional dose rates.

Abstract Text Studies suggest that DEI (Diversity, Equity and Inclusion) in the medical workforce may improve patient care and have a positive impact in academic environments, improving science and education. A survey was launched in collaboration with the Young and National Society Committees of ESTRO to provide a benchmark of DEI amongst professionals in the field of Radiation Oncology in Europe. In this talk, I will first describe how this yESTRO project on DEI was developed: - from the submission of the idea & approval by ESTRO - to the obtention of a licensing agreement with the University of Massachusetts - and the creation of the survey. I will then go through the results, and the collaboration that was developed for their analysis. Finally, I will discuss what could be the next steps at ESTRO, using these results as a basis for future projects to promote DEI.
