Bookmark and Share



The Late-Breaking Research sessions and the Late-Breaking Abstract titles are now available for browsing and searching in the Online Itinerary Planner. The Late-Breaking Abstract bodies will be posted to the online planner on Friday, March 30. [Note: Some Late-Breaking Abstracts have been embargoed and will be posted to the online planner at or after the time of presentation. Copies of the embargoed abstracts will also be distributed at the sessions.]


Because the Proceedings of the AACR is intended to represent a summary of all of the abstract presentations at the Annual Meeting, every abstract that has been accepted for publication in the Proceedings of the AACR must also be presented at the meeting. Specifically, the author listed as the presenter for an abstract submission must attend the session in which the abstract is scheduled to discuss in detail the research outlined in the published abstract, according to the specific guidelines of the session. If, due to unforeseen circumstances, the designated presenter is unavailable to attend the session to present the abstract, he or she must contact the AACR Program Development Department to designate a co-author to serve as the presenter. If no authors are available to present the abstract, the presenter must withdraw the abstract immediately by contacting the AACR Program Development Department at (215) 440-9300 or

    Failure to comply with these regulations pertaining to abstract presentation may result in actions including, but not limited to:
  • The withdrawal of the abstract from the session
  • The removal of the abstract from the online Proceedings
  • The loss of future sponsorship privileges for the sponsor of the abstract
  • The loss of future abstract submission/authorship privileges for the presenter of the abstract


The AACR cannot comply with any request for withdrawal of an abstract that will delay the publication of the Proceedings. However, requests to withdraw abstracts will be accepted through Thursday, January 26. Requests to withdraw late-breaking abstracts will be accepted through Wednesday, February 29. Withdrawal requests must be made in writing and sent by fax to (267) 825-9565. Withdrawal requests must include the abstract control number and title as well as an explanation of the reason for withdrawal.
