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.

A skeleton indicating the type of data that will be available by the late-breaking abstract deadline must be submitted online by the regular abstract deadline on 8 May 2019. 

Submitters of preliminary versions receiving approval to proceed must submit the final LBA by 21 August 2019, 21:00 CEST (Central European Summer Time).

Trial in progress abstracts (TiP)

Trial in Progress (TiP) abstracts in all phases of clinical research (phases I to III) may be submitted to ESMO 2019.

It is expected that abstracts submitted as Trial in Progress (TiP) are ongoing trials that have not reached any protocol-specified endpoints for analysis and consequently will only require the completion of two (2) sections: Background and Trial design. 


  • Recruitment must have already begun or have been completed by the abstract submission deadline of 8 May 2019.
  • Abstracts including results or preliminary data will be rejected.
  • Trial in Progress abstracts will NOT be considered for Proffered Paper (oral) presentation or Poster Discussion.
  • Encore TiP abstracts will NOT be accepted.

Presentation and publication of accepted abstracts

The ESMO 2019 Scientific Committee will select abstracts for presentation during the Congress based on the following possibilities:

Presidential Symposium: Oral presentations by authors of the very best submitted abstracts containing 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.

Poster Discussion: Presentation and analysis by an invited speaker highlighting important findings within a disease type or about a common theme plus interactive audience discussion.

Poster: Display sessions for review, discussion and questions. Rotated by category, posters will be displayed for one day of the Congress and the presenting authors must be available for Q&A for one hour to represent their work. 

All accepted abstracts, including Late-breaking, will be published online only in the ESMO 2019 Abstract Book.
