AACR Abstract Submission System
Authors must submit abstracts for presentation at the Annual Meeting 2019 using the AACR Abstract Submission System. You can create, modify, and submit abstracts until the Nov. 15, 2018, abstract deadline.

Responsibilities of Authors
By submitting an abstract for presentation at the AACR Annual Meeting, abstract authors agree and/or attest to the following:

  • Support for Abstract/Verification of Authorship. It is assumed that all authors accept sole responsibility for the statements in their abstract. It is also assumed that the submitting author has ensured that all authors have agreed to the submission of the abstract and to their being listed as contributors prior to submission. Authors will be notified of their inclusion on an abstract via email.
  • Sponsorship of Abstracts. The submitting author must provide the name of an AACR member who has agreed to sponsor the abstract, and the submitting author must attest that the permission of the member sponsor has been secured prior to initiating an abstract submission.
  • Transfer of Copyright. On behalf of all authors, the submitting author must assign and transfer copyright for the abstract to the AACR, Inc.
  • Presentation of Abstracts. The submitting author for each abstract must designate a presenter who agrees to register for the meeting and attend the corresponding session to discuss in detail the research presented in the published abstract. If the assigned presenter cannot attend the meeting, the authors are expected to designate a replacement or withdraw the abstract.
  • Confirmation of No Prior Publication/Presentation. Authors who submit an abstract confirm that they have not previously published these data, that they have not previously presented them at a large national annual scientific meeting, and that they are not planning to present or publish them prior to the dates of the AACR Annual Meeting 2019.

    Exception: Encore presentations are permitted for clinical trial abstracts that are submitted for the Jan. 10, 2019, clinical trial deadline. During the submission process, authors of encore clinical trial abstracts must provide the date and name of the meeting at which the original trial abstract was presented.
  • Confidentiality of Abstracts. Authors must keep the content of their abstracts confidential until they have been made publicly available. In accordance with the AACR's embargo policy, abstracts will be posted to the AACR Online Itinerary Planner on Wednesday, February 27, 2019 at 4:30 p.m. ET, excepting those abstracts that have been selected for inclusion in the AACR press program. Abstracts in the AACR press program will be made publicly available at the date and time of presentation, either at the meeting or an official AACR press conference.

Content of Abstracts
Each abstract should contain: (a) an introductory sentence indicating the purposes of the study; (b) a brief description of pertinent experimental procedures; (c) a summary of the new,
unpublished data; and (d) a statement of the conclusions.

Abstracts should be carefully proofread to avoid errors in the published literature. American spelling should be used
throughout; for more information regarding American spelling, please refer to Scientific Style and Format: The CSE Manual for Authors, Editors, and Publishers, Eighth Edition (Council of Science
Editors, 2014). 

Abstract Control Number An Abstract Control Number (e.g., 18-A-1234-AACR) will be assigned to each abstract submitted online and will be listed on all email correspondence regarding the abstract. Please refer to the Abstract Control Number in any abstract communications.

Financial Relationships of Coauthors
Per ACCME regulations, the AACR must collect information on the financial relationships of all meeting presenters and abstract authors. You will be asked to disclose your financial relationships and the financial relationships of all of your coauthors. Learn more about financial relationships.

Length of Abstracts
The combined length of the abstract body, title, and tables may not exceed 2,600 characters, not including spaces and the author string. Tables count for 800 characters against the limit. Submission cannot be completed for abstracts that exceed this limit.

Abstract Category and Subclassification
You must select a category and subclassification for your abstract. View categories and learn more

Disclosure of Chemical Structures 
At the time of abstract submission, the submitting author is required to state whether chemical compounds were used in the scientific work to generate the data in the proffered paper. Chemical compounds are defined as low-molecular-weight (generally <1000 g/mol) organic or inorganic molecules, peptides, or proteins/nucleic acids co-crystallized with low-molecular-weight molecules.

If chemical compounds were used, the corresponding author is further required to indicate whether the complete chemical structures of the compounds used will be disclosed at the time of presentation at the meeting. The chemical structures are not required to be included at the time of abstract submission; rather, an indication of the intent to disclose any such structures at the time of presentation is required.

The Program Committee will then evaluate the information provided by the corresponding author and determine the acceptability of the proffered paper for presentation. Those who do not intend to disclose chemical structures may have their abstracts rejected for participation; however, a limited number of these abstracts may be accepted for presentation if deemed to be of sufficient scientific merit.

Submission Fee
Each abstract submitted must be accompanied by a $65 abstract submission fee. The submission fee can be paid by credit card or check. The fee is nonrefundable regardless of the final disposition of the abstract.

Abstract Deadline
The deadline for abstract submissions is 11:59 p.m. U.S. ET, Thursday, Nov. 15, 2018. Abstracts submitted after the deadline will not be considered by the Program Committee. No changes may be made to abstracts after the Nov. 15, 2018, deadline.

Note: Submitting an abstract for presentation at the AACR Annual Meeting 2019 does not constitute registration for the meeting. Abstract presenters must register to attend the meeting by submitting the registration form or by registering online.

If, due to unforeseen circumstances, the designated presenter is unavailable to attend the session to present the paper, he or she must contact the AACR Program Development Department to designate a coauthor to serve as the presenter. If no abstract authors are available to present the data, they must withdraw the abstract immediately by contacting the AACR Program Development Department at (215) 440-9300 or

  • The loss of future abstract submission/authorship privileges for the presenter of the abstract
