Late-breaking abstracts (LBA)

Late-breaking abstracts may be submitted for high quality, new research findings with implications for clinical practice or understanding of disease processes.

The work must not have been previously published in any publication in a peer review setting or presented at a meeting of any other scientific organisation prior to ELCC 2020.

A preliminary abstract indicating the type of data that will be available by the late-breaking abstract deadline must be submitted online by 14 January 2020 and the intent to submit a late-breaking abstract check-box must be ticked.

Only abstracts for which no conclusive data are available at the time of the abstract submission deadline of 14 January 2020 will be considered for late-breaking status.

The final late-breaking abstract deadline of 10 March 2020 is under no circumstances to be considered as an extension of the general submission deadline.

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 ELCC 2020.

It is expected that abstracts submitted as Trial in Progress 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
  • Trial design


  • Recruitment must have already begun or have been completed by the abstract submission deadline of 14 January 2020.
  • Abstracts including results or preliminary data will be rejected.
  • Trial in Progress abstracts will be accepted for Poster outcome only.

Abstracts will be reviewed by the ELCC 2020 Scientific Committee and considered on the merits of the scientific and clinical rationale of the trial.

Publication schedule for accepted abstracts

  1. Abstracts accepted for presentation at ELCC 2020 as Proffered Paper, Mini Oral and Poster will be published online on the ESMO website at 12:00 CEST on Wednesday, 8 April 2020.
