Culture of Respect

In an effort to improve practice around using respectful language regarding patients and colleagues, ASTRO Leadership has developed Culture of Respect Guidelines that we ask all presenters to review and adhere to during their presentations at the Annual Meeting and all ASTRO meetings. The language addresses the importance of using professional introductions, correct pronunciations of names and correct use of pronouns, as well as respectful language around patients. The guidelines provide examples of appropriate and inappropriate language that you will find helpful as you prepare your presentation.

Faculty Best Practices Training

Abstract Presenters

Oral Abstract Presenters, Quick Pitch Presenters and Poster Presenters can find more information below specific to their presentation format.

Oral Presenters


Oral scientific sessions are labeled as “SS 01, SS 02,” and are either 60- or 75-minutes in length. The session will contain either six or seven abstracts depending on the scheduled session time. Each speaker is given seven minutes to present their abstract followed by a three-minute question and answer period, for a total of 10 minutes per abstract.

All abstract presenters must deliver their presentations in person, in San Diego. Unfortunately, we cannot accommodate virtual presentations. If you are unable to attend for any reason, please decline your role and reach out to ASTRO staff for assistance, as needed.


All abstract authors must submit their slides ahead of time. Slides can be submitted virtually through the Speaker Center until Tuesday, September 26, 2023, at 11:59 p.m. Pacific time. All speakers must also review their slides with ASTRO AV technicians in the Speaker Ready Room once you arrive on site. If you are unable to upload before September 26, at 11:59 p.m. Pacific time, you may upload directly in the Speaker Ready Room. We highly encourage all presenters to upload before the deadline in order to ensure there are no AV concerns during your session and to allow your moderator time to review your slides prior to the session.

If your session has a Discussant, you must submit a second set of summary slides for the Discussant (more information is included below). The Discussant slides are due no later than Friday, September 8, 2023. If you fail to meet this deadline, your abstract will not be included in the Discussant's presentation.


Each session is assigned two moderators to keep time and assist speakers with the question-and-answer period. Presenters will be able to see their session Moderators in the Speaker Center.


Scientific Sessions may also include a Discussant to provide a background to frame the presentations, emphasize the key points or provide an alternative point of view of the presented abstracts. IF your session has been assigned a Discussant to discuss your paper, you will be notified in a subsequent email to forward three to four summary slides and a take-home message in PowerPoint by Friday, September 8, 2023. Your slides will be given to the Discussant prior to the Annual Meeting to aid them in the preparation of their presentation and slides.

Presenters will be able to see their Discussant in the Speaker Center.

Quick Pitch Presenters


Quick Pitch sessions are 60-minutes long. Each session will include six presenters who have five minutes and five slides to present the highlights of their study and a take-home message. These sessions will include time for Q&A at the end of the session, with the two moderators and six presenters.

All abstract presenters must deliver their presentations in person, in San Diego. Unfortunately, we cannot accommodate virtual presentations. If you are unable to attend for any reason, please decline your role and reach out to ASTRO staff for assistance, as needed.


All Quick Pitch abstract authors must submit their slides ahead of time. Slides can be submitted through the Speaker Center until Tuesday, September 26, 2023, at 11:59 p.m. Pacific time. All presenters must also review their slides with ASTRO AV technicians in the Speaker Ready Room upon arrival.


Each session is assigned two moderators to assist speakers with the question and answer period. Presenters will be able to see their session moderators in the Speaker Center.

Poster Presenters

Nearly 1,650 digital posters will be available to view both at the in-person meeting, and on the virtual meeting platform. All poster presenters must record an audio narration to be used as your presentation. This will allow both in-person and virtual meeting attendees to view all poster presentations.

Posters will be available for viewing and listening on kiosks in San Diego and through the Annual Meeting Portal, MyASTROApp and ASTRO website via the Virtual Poster Library. Posters will be available to view throughout the meeting and beyond. Poster Q&A Sessions will be scheduled based on disease sites throughout the meeting dates (October 1-4, 2023). During the scheduled Poster Q&A Session time, attendees will have the opportunity to ask questions to specific poster presenters. Poster presenters are required to attend the Poster Q&A sessions to answer questions from the audience.

There will not be any virtual poster sessions.

Depending on the publication details and size of the other meeting, your abstract may be withdrawn from the ASTRO meeting in order to maintain the integrity of our scientific program.

Vendor/Commercial Names

To remain in compliance with the ACCME guidelines, ASTRO must avoid any commercial bias in the scientific and educational programs at the Annual Meeting. Vendor names or names of commercial products or services will be removed from all abstracts, at ASTRO's discretion.

Embargo and Press Program Policy

All abstracts to be presented at ASTRO’s Annual Meeting are embargoed until the date and time of scientific presentation or presentation at an ASTRO news briefing, whichever occurs first. The embargo policy applies to all abstracts regardless of whether information is obtained from another source.

Embargo violations by abstract authors and/or sponsors may result in removal of the abstract from the scientific program. The submitting author is responsible for conveying this information to all co-authors, and notifying financial and other sponsors about this embargo policy.

All abstracts accepted for presentation at the ASTRO Annual Meeting may be highlighted in ASTRO’s Press Program. All submitters agree to cooperate in the publicity of their study. Questions regarding the embargo or press policy may be directed to ASTRO’s media relations team.
