ABSTRACT SUBMISSION

Abstract submission for ESTRO 2027 is now open. The deadline for submission is 11 November 2026, 23:59 CET.

The peer review and selection process take place in December and January. Selection results will be communicated by beginning of February 2027.

LANGUAGE MATTERS -  A Call to Change the Perception of Radiotherapy

Words influence perceptions. In our daily work, some of the terminology we use in radiotherapy can sound unnecessarily alarming or even misleading to patients, caregivers, policymakers, the general public and to colleagues outside our specialty. By adopting a more balanced and patient-friendly language, we can improve understanding and build greater trust in our field.

LATE-BREAKING ABSTRACTS

Late-breaking abstract submission opens on 17 March 2027. The deadline for submission is 31 March 2027, 23:59 CET.

Late-breaking abstracts must present timely findings which were not available at the time of the deadline (11 November 2026). The late-breaking abstract deadline is not intended to be a second deadline for abstract submissions. Abstracts deemed to not be truly late-breaking are rejected.

The ESTRO annual meeting is growing at an accelerated pace, with record numbers of delegates and submitted abstracts in 2026. With the Championing Scientific Excellence initiatives will continue for ESTRO 2027, to make it the event to submit your top research to.

CALL FOR ABSTRACTS: Green Journal Collaboration with The Lancet Oncology

After the enormous success in 2025 and 2026, Radiotherapy & Oncology (the Green Journal) and The Lancet Oncology are once again joining forces for ESTRO 2027. The top clinical trials and other transformative research abstracts will be selected for a special Green Journal - The Lancet Oncology joint session and could be published in either journal.

ABSTRACT SUBMISSION DEADLINES

The deadlines for both regular abstract submission and late-breaking abstract submission have been moved back to ensure that you are able to submit your most up-to-date science to the congress.

• Regular abstract submission deadline: 11 November 2026
• Late-breaking abstract submission deadline: 31 March 2027

ABSTRACT PRESENTATIONS

The latest research will be presented in a plenary setting, without other sessions taking place in parallel, ensuring maximum exposure for the most up-to-date science. Many of your proffered papers will be followed by discussants to highlight the presented science. Some sessions will also include a panel of experts to discuss the importance of your presented work.

All abstract presentations, from proffered papers to mini-orals to poster discussions, will be recorded to ensure that delegates have the chance to see all your research submitted to the congress.

With the increasing number digital posters included in the programme, the new category of Poster Highlights will be continued in 2027. This will give the opportunity for the top-scoring digital posters to be promoted and give you the chance to network with delegates and discuss your work.

The abstracts scoring in the top 5% will receive a certificate attesting to the quality of the submitted science.

MEDIA ACTIVITIES

We will build on the success of the press activities of ESTRO 2026, inviting journalists to cover the breaking science and latest research presented at the congress. Collaborations with leading oncology news sites will be repeated. Along with social media ambassadors and daily congress email reports, communications before, during and after the congress will promote the important work you will present at the congress.

ESTRO will apply for CME accreditation (ECMEC®s) to the European Accreditation Council for Continuing Medical Education (EACCME®). The EACCME® is an institution of the European Union of Medical Specialists (UEMS), www.uems.eu.We expect to receive 22 credits.

Each medical specialist should claim only those credits that they actually spent in the educational activity. Delegates should ensure that their badges are scanned for each session they attend.

After the congress, delegates will receive the post-congress email where they can complete the CME evaluation. The CME certificate will then be sent via email.

Through an agreement between the European Union of Medical Specialists and the American Medical Association, physicians may convert EACCME^® credits to an equivalent number of AMA PRA Category 1 Credits™.  Information on the process to convert EACCME^® credits to AMA credits can be found at https://edhub.ama-assn.org/pages/applications.

Live educational activities occurring outside of Canada, recognised by the UEMS-EACCME^® for ECMEC^® credits are deemed to be Accredited Group Learning Activities (Section 1) as defined by the Maintenance of Certification Program of the Royal College of Physicians and Surgeons of Canada.

Information regarding the conversion of EACCME^® credits

Credit will be converted based on one (1) hour of participation equalling one credit for all activities. Physicians wishing to convert EACCME^® credits to AMA PRA Category 1 Credit™ will be required to access the AMA website at https://edhub.ama-assn.org/pages/applictations to obtain the necessary paperwork and instructions. Physicians and other health care professionals will be required to pay a processing fee to the AMA.

For other countries, please contact the relevant national/regional accreditation authority.
