Vienna, Austria

ESTRO 2023

Registrations are open

It is my great pleasure to invite you to ESTRO 2023 which will take place from 12 to 16 May in Vienna, Austria.

The ambition of ESTRO to further reinforce radiation oncology as a core 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.’. After a challenging couple of years, it is more important than ever before to gather as a community to connect, share and learn.

The congress theme, From innovation to action, builds on previous topics and focusses on how we translate and implement research into practice.  It will be reflected throughout the programme via state-of-the-art sessions. Along with symposia, debates and teaching lectures, the scientific programme will feature panel discussions and pitch sessions with the aim of increasing interaction between faculty and audience. Joint sessions with partner associations aim to connect delegates with new communities and increase the reach of the ESTRO population. Fostering the development of young radiation oncology professionals remains a top priority for ESTRO and therefore the Young Scientists track will continue to provide educational activities focussed on those in the earlier stages of their careers.

This year we will continue to optimise the contributions from submitted abstracts. The best abstract submitted to each track will be celebrated in the Best Proffered Papers plenary session. Other sessions will showcase the Latest Clinical Trials and Late-breaking Papers. The successful mini-oral sessions will continue, enhancing the visibility of your submitted research, while poster discussion sessions offer you a platform to showcase your work. We will continue to emphasise the interdisciplinarity of the ESTRO scientific programme by calling for abstracts which are of interest to a broad range of disciplines.

Networking with corporate partners is always invaluable. ESTRO 2023 will host Europe’s largest industry exhibition in radiation oncology. It will offer you a unique opportunity to interact with industry leaders and to find out about the latest developments in technology, techniques and oncology products.

We look forward to welcoming you in Vienna.

With warm regards,
