Late-breaking abstracts (LBA)
Late-breaking abstracts may be submitted for high quality, new research findings from randomised phase II or phase III trials with implications for clinical practice or understanding of disease processes.
The final late-breaking abstract deadline of 7 October 2025 is under no circumstances to be considered as an extension of the general submission deadline (12 August 2025).
Trial in progress abstracts (TiP)
Trial in Progress (TiP) abstracts in all phases of clinical research (phases I to III) may be submitted to the ESMO Asia Congress 2025.
It is expected that abstracts submitted as Trial in Progress are ongoing trials that have not reached any protocol-specified endpoints for analysis.
Presentation and publication of accepted abstracts
The ESMO Asia 2025 Scientific Committee will select abstracts for presentation during the Congress based on the following possibilities:
- Presidential Symposium – Oral presentations by authors presenting cutting-edge and significant clinical practice-changing studies, followed by expert discussion and perspectives.
- Proffered Paper – Oral presentations by authors presenting original data of superior quality, followed by expert discussion and perspectives.
- Mini Oral – Short oral presentations by authors presenting data of good quality, followed by expert discussion and perspectives.
- Poster – Paper poster presentation for review and discussion onsite. Presenting authors must attend the Congress in person and represent their work. Preparation of an e-Poster is also mandatory for inclusion in the e-Poster Gallery.
- e-Poster - Electronic poster in PDF format for inclusion in the e-Poster Gallery. Presenting authors of e-Posters are not required to attend the Congress in person to represent their work. Paper posters are not to be prepared, and poster boards will not be provided.
All accepted abstracts, including late-breaking abstracts, will be published online only in the ESMO Asia Congress 2025 Abstract Book, a supplement to the official ESMO journal, Annals of Oncology.
