It is my great pleasure to invite you back to Vienna, Austria for ESTRO 2025 which will take place from 2 to 6 May. Building on the huge success of previous congresses in this vibrant city, situated ideally in the centre of Europe, we will convene the radiation oncology community for five days of learning, collaborating and connecting.

The ambition of ESTRO to further reinforce radiation oncology as a key partner in multidisciplinary cancer care, and to guarantee accessible and high-value radiation therapy for all cancer patients who need it, is expressed in the society’s vision statement for 2030: ‘Radiation Oncology. Optimal Health for All, Together.’

Continuous evolution and refinement of radiation oncology is one important path of innovation to achieve this goal. ESTRO 2025 will put an emphasis on breakthrough research and innovation. Such revolutionary innovation is happening within our discipline, and even more opportunities open by collaboration and partnership with neighbouring and even distant fields of research. With this aim, the congress theme is Transformative Innovation Through Partnership. The programme will focus on how all stakeholders can learn from each other and cooperate to push the boundaries of radiation oncology and multidisciplinary cancer care in general. The theme will be reflected throughout the programme via state-of-the-art sessions.
