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.

Abstract Guidelines
  • Follow the online instructions

Late-Breaking Abstract Submissions
The Congress late-breaking policy allows the submission of late-breaking abstracts that include results of phase III studies or potentially practice-changing results for which no preliminary data are available at the time of the abstract submission deadline.

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.

Changes to Abstracts
You may change your abstract even after finalizing up until the submission deadline of 8 March 2018, 16:00 PM CET.  Once the submission site has closed, changes to abstracts will not be accepted.
