Trials in Progress Abstract Submissions

The 20th ESMO World Congress on Gastrointestinal Cancer is now accepting Trials in Progress abstract submissions in all phases of clinical research (phase I to phase III). All abstracts submitted as Trials in Progress are ongoing trials that have not reached any protocol-specific endpoint for analysis and will only require the completion of two sections: Background and Trial Design. It is a requirement that recruitment must have already begun or have been completed by the abstract submission deadline.

Late-Breaking Abstract Submissions

An abstract template should be submitted by the regular abstract deadline (8 March). The template should include: title, author list, and a description of the study. A final abstract version must be submitted by 17 May and will be published in a supplement of the Annals of Oncology. Once the final version is available, please email so we can provide you with late-breaking abstract submission instructions.

Even after finalizing, you may change your abstract up until the submission deadline of 8 March 2018 at 16:00 CET. Once the submission site has closed on 8 March 2018 changes to abstracts will NOT be accepted.
