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.
Content of AbstractsEach 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unpublished data; and (d) a statement of the conclusions.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

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.
Presentation of Proffered Papers at the AACR Annual MeetingEvery proffered abstract that has been accepted for publication in the
Proceedings must have a corresponding presentation at the meeting. Specifically, the author listed as the presenter for an accepted proffered paper must attend the corresponding session 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 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
Failure to comply with these regulations pertaining to abstract presentation may result in actions including, but not limited to:
