Due to the growing Coronavirus pandemic, the World Cancer Congress, originally scheduled to take place on 20-22 October 2020, has been delayed to 16-18 March 2021 and will take place in Muscat, Oman. Therefore, the call for abstracts has now been closed and will re-open on 30th September 2020. Please read on for more information about the abstract process and its updated timeline. 

Have you already submitted an abstract

All abstracts submitted by 6th April 2020 will be kept in the submission system and rolled over as "new submissions" for the delayed Congress edition held on 16 - 18 March 2021.

Abstract authors will have the option to edit their submission(s) when the system opens again for the "new call for abstracts" on 30th September 2020. This will give authors the opportunity to refresh the content of their abstract and make it more topical for a Congress that is held in March 2021.

  • This implies that all abstracts (even the ones currently accepted) will need to be reviewed again as part of the 1st tier process to ensure the content is not out-dated and remains relevant. 
  • Abstracts which have already received acceptance, will be encouraged to edit their submission(s) in order that they are up to date.
  • The 2nd tier review process (scoring) for the accepted batch of abstracts will now take place from 30 November 2020 - 8 January 2021 instead. 
  • If you would like to withdraw your abstract or for any other enquiries regarding your submission, please contact Delegate Services managed by UICC's partner agency K.I.T Group at 2020wcc@kit-group.org

1. Submission category

Three types of submissions are welcomed at the Congress:

  1. Abstracts on scientific studies describing the collection, analysis and interpretation of cancer-relevant data (clinical, behavioural, epidemiological, etc)
  2. Summaries of practice, policy and advocacy reports with impact describing innovative cancer and NCD programmes in detection, care, support, prevention, organisation.
  3. Summaries of fundraising campaign reports describing programmes to build public support to fund or donate to cancer and NCD control causes.
2. Review process and format of presentations

A two-tier review process has been put in place for abstracts submitted as part of the Congress.

In the first-tier review process, the Abstract Committee will screen each submission and each submitter will be notified within two weeks if their abstract has been accepted or rejected. 

Important - Abstracts that were submitted and accepted before 6th April 2020 will be reviewed again as part of the first-tier review process, to ensure they remain topical and up-to-date for a Congress held in 2021. Authors are highly encourage to log into the abstract submission platform again, AFTER 30 September, to edit and update their abstract, if necessary. 

Accepted abstracts will undergo a secondary review process conducted via an International Panel of Reviewers, once the call for abstracts has closed (20 November 2021).

Abstracts with the highest average score will be presented at the World Cancer Congress under one of the following formats:

  • Abstract oral: 8-minute presentation in front of a large audience (approximately 100 people)
  • Rapid Fire: 3-minute presentation in front of a large audience (approximately 100 people)
  • E-poster pod presentation: 3-minute presentation in an e-pod. The e-poster will be displayed on an e-poster screen and presented at a given time during one of the networking breaks. Each e-pod presentation will take place in an e-poster pod seating approximately 35 people.

Each accepted abstract will be available for consultation on the WCC abstract e-library.

Please read the complete submission guidelines here.
