Presentation Type

Abstracts can be considered for “Oral or Poster” OR “Poster ONLY.” Those who select “Poster ONLY” will not be considered for oral presentation within SITC’s Annual Meeting. Selecting “Oral or Poster” will allow you to be considered for oral presentation within the Annual Meeting and/or poster presentation.

Submission Guidelines

Below are the guidelines for your abstract submission. The submitting author is responsible for assuring that the abstract adheres to these.

General Requirements

  • Type the text unjustified without hyphenating words at line breaks.
  • Use single line spacing. Use hard returns only to end headings and paragraphs.
  • Abbreviations should be used as sparingly as possible and should be defined when first used.
  • All abstracts must be in English. Spelling within any one abstract should be US English or UK English, but not a mixture.
  • In most cases, Greek letters and other special characters will transfer from your word processing software via copy and paste functions. If you are unable to reproduce a particular special character, type out the name of the symbol in full.
  • SI units should be used throughout (liter and molar are permitted, however.)


The title must be entered exactly as it should appear and should be in sentence case. Do not put the title in quotes, underline it, or use punctuation. The title can be a maximum of 200 characters, including spaces.


Example: Novel pharmacologic approach to enhance the epigenetic and immune priming effect of decitabine in patients with advanced non-small cell lung cancer

Session Selection

Abstract submitters that select the presentation type “Oral or Poster” will be asked to indicate the session they feel the abstract would most belong in. Abstracts will be reviewed and chosen by the Co-Chairs of the session selected.

Abstract Category

All abstract submitters will be asked to indicate the category that they feel the abstract most belongs to. If accepted, this selection will determine the category your abstract is listed under in publications such as the Annual Meeting Abstract Book and the JITC supplement as well as the category used for poster displays.


All abstract submitters will be asked to indicate keywords for their abstract. Keywords are included in the Annual Meeting Abstract Book, website and app publications to assist users in searching for abstracts. Up to 10 keywords can be selected.

Abstract Structure

The following is included in the abstract body and must not exceed 400 words total. 


*For Clinical Trials In Progress, if results and conclusion are not applicable please put N/A when submitting

The following are no longer required to stay within the 400 word limit.

Trial Registration: If applicable, abstracts related to randomized controlled clinical trials (RCTs) should include the trial registry along with the unique identifying number. Trial registers that currently meet the publisher’s requirements can be found at
References: Citations to references should be included in square brackets [1,2]. All references need corresponding citations in the text, and vice versa.

  • Primary clinical endpoint for analysis
  • Type of analysis
Lab-Based Study

Late-Breaking Abstract Information and 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 33rd 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 33rd Annual Meeting.

Late-breaking abstracts are considered for, but not limited to, oral abstract presentations during the Late-Breaking Abstract Sessions from Noon – 12:30 p.m. on Friday, Nov. 9 and 11:35 a.m. – 12:05 p.m. on Saturday, Nov. 10.
