Call for Abstracts

Helpful Tips Before You Begin Your Submission:

• To submit an abstract, you will need to log in with an ASCO.org account. If you are not an ASCO member, you can create a guest account. The person submitting the abstract is not required to be an author on the abstract and will be able to select the first/presenting author on the designated step.
• Abstract submissions will be automatically assigned a temporary abstract ID once they complete the Title step in the submitter.
• Abstracts may be viewed and modified at any time between submission and the deadline by the designated submitter or the first author. Your ASCO username and password are required to log in and edit the submission.
• Please note that you will be charged a nonrefundable $60 (USD) fee to complete your submission.
• All authors' conflict of interest disclosure information is required to complete a submission. To do so:
  • Distribute the Coauthor Disclosure Form to your coauthors, collect responses, and manually enter them at the COI Disclosure step. It is recommended to collect this information before starting your submission;
  • OR Authors can submit their disclosure electronically through the ASCO Disclosure Management System. If an author has provided his/her disclosure through the system already, the information will automatically populate across all of their submissions.
