Late-Breaking Abstract Criteria & Eligibility

  • Late-breaking abstract submission is solely for abstracts with late-breaking data and not for abstracts submitted “late”. The late-breaking abstract deadline is not intended to be an extension of the general submission deadline.
  • Late-breaking abstracts highlight novel and practice-changing studies, and only apply to data that would have not otherwise have been presented as an abstract at the SITC 32nd Annual Meeting.
  • Examples of acceptable late-breaking abstracts include the following (in each case, results were not available or significant by the regular abstract submission deadline):
    • Results of a practice-changing prospective Phase III clinical trial
    • Phase II study showing anti-tumor activity in a novel context
    • An early clinical trial with novel proof-of-principle data
    • Demonstration of novel cancer biology with therapeutic implications
  • For clinical studies, authors need to justify late consideration by documenting the closure date of the study, and submit a late-breaking abstract application by the regular abstract submission deadline (Aug. 1). This application needs to include necessary abstract information (without results and conclusions) and incorporate the primary clinical endpoint for analysis, type of analysis, date of planned analysis, and planned statistical methods for analysis.
  • Laboratory-based studies need to be justified within the author's late-breaking abstract application. Authors need to specify why experiments could not be completed before the standard abstract deadline.
  • The data in the abstract must not be published prior to the SITC 32nd Annual Meeting.
