Vienna, Austria

ESTRO 2023

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,

ESTRO welcomes the interest of the press in cancer issues and is happy to provide assistance to journalists attending the ESTRO 2023 from 12-16 May 2023, or using the congress online platform, as a resource in their coverage of cancer issues.



The congress is open to bona fide representatives of print and electronic media. Press registration is free of charge to journalists who meet the criteria outlined in this section.

Journalists are required to submit appropriate supporting documents as part of the registration process including:

  • a valid and recognised press card
  • a commissioning letter on headed paper from a recognised news organisation or publication, and two recently published by-lined articles for freelancers.

Registration for the ON SITE congress in Vienna:

The original of the press card or of the commissioning letter will also have to be presented at the conference registration desk together with a valid passport or ID-card.

Media registration in advance is strongly recommended. The documents should be sent, together with the media registration form, to Cécile Hardon-Villard, Communication Manager at the ESTRO office, by email: (with scanned documents).

The media registration form can be downloaded by clicking here.

Press registration is not available to Industry or its public relations representatives or event management, nor to media outlet managers, marketing, sales or communication representatives. They are however welcome to register as regular attendees or visitors.

Business cards or membership cards from news media, communications, or writers’ organisations are not sufficient to establish eligibility.

Journalists must register in person. Applications for media registration made via pharmaceutical, marketing or public relations companies will not be considered.

Information regarding media registrations belongs to ESTRO. Past and current media lists are not available to be given, rented or sold.

The ESTRO Office reserves the right to withhold approval of press registration and press accreditation if the applicant does not satisfy the required criteria, or if the form is sent without the requested supporting documents. The decision of the ESTRO Press Office is final regarding all press registration requests.



The ESTRO 2023 abstracts will go up online on the congress website one month before the congress at and can be reported from that time onwards.

Companies wishing to organise a news conference during the congress should send a request in writing to Cécile Hardon-Villard, Communication Manager at the ESTRO office, by email: It is not permitted to schedule press events, either on or off site, to coincide with the key ESTRO 2023 sessions.

There are two types of media materials and events permitted at the ESTRO meeting:

1. Those that pertain to presentations being made at the meeting in oral or poster sessions

2. Those that relate to products/services offered by companies exhibiting at the meeting

1. Media materials pertaining to presentations in oral or poster sessions

The programme for any third-party news conference should be submitted to, and agreed by, the ESTRO Communication Office before any invitations are sent out. This applies to any media event, regardless of whether it is held on or off site.

Third party press releases must be labelled clearly with the abstract number, time and date of presentation at the congress, and submitted to, and agreed by, the ESTRO Communication Office before they are issued to the media. 

Third party press materials are not permitted outside the exhibitor’s booth.

Third party media materials (including press releases, media invitations, flyers and posters) must not contain the logos of ESTRO, and they must not be presented in any way that could be construed as suggesting endorsement by ESTRO.

2. Media materials relating to products/services offered by exhibiting companies

Media materials that do not relate to an oral or poster presentation at the meeting, and instead are designed to give information about products that exhibiting companies wish to promote at the meeting are permitted on two conditions: 1) they are submitted to and approved by ESTRO Communication Office prior to the start of the meeting, and 2) they are distributed from the exhibitors’ stall.

These media materials must not contain the logos of ESTRO, and they must not be presented in any way that could be construed as suggesting endorsement by ESTRO.



Any national society or local organisation planning to organise press activities needs to inform the ESTRO office at the earliest opportunity. The programme for any national society or local organisations’ news conference should be submitted to and agreed by the ESTRO Communication Office before any invitations are sent out. This applies to any media event, regardless of whether it is held on or off site.

National societies and organisations press releases must be labelled clearly with the abstract number, time and date of presentation to the congress, and submitted to, and agreed by, ESTRO Communication Office before they are issued to the media. If the press release is not in English, an outline of a few sentences in English will be requested.

If the media event and/or press release for a national society or local organisation is unrelated to a specific abstract or scientific session, then the content must be discussed with the ESTRO Communication Office and approved before any plans are finalised or media invitations issued. The ESTRO Communication Office’s decision on whether or not to allow these events to take place will be final.

National societies and organisations media materials (including press releases, media invitations, flyers and posters) must not contain the logos of ESTRO, and they must not be presented in any way that could be construed as suggesting endorsement by ESTRO unless they are part of a media programme joined with ESTRO.


ESTRO does not make media lists available to any third-party organisations.
