Presentation and Publication
The titles and presenting authors of all regular abstracts scheduled for presentation at this conference will be available online prior to the conference. With the exception of abstracts selected for a conference press program (if applicable), all conference abstracts will not be available until the Conference App is released on September 16. Abstracts will be available online as a supplement to the AACR journal, Cancer Immunology Research, within 2-3 months of the conference. Every effort will be made to reproduce the content of the abstracts as submitted, except in certain circumstances where changes may be made to comply with the conference style guide.

Poster boards dimensions will be provided in email correspondence to the Submitting Authors.  The organizers will provide poster numbers and pushpins.

From the accepted posters, a small number of highly rated abstract authors will also be invited to deliver short oral presentations of their work during the general sessions.  All abstracts will be considered.  Instructions will be sent to the Submitting Authors with the date, time, and format for these presentations.

Conference Registration
Presenting Authors must register for the conference and attend the session in which the abstract is scheduled to discuss the research in detail, according to the specific guidelines of the session.  If an abstract is not accepted, the presenter may request a full refund of the registration fee.

Request for Withdrawal
Once an abstract has been submitted, it may be withdrawn only by written request from the Submitting Author.  The request may be sent by email to and must be received at least 30 days prior to the start of the conference.
