Oral Abstract Presenters, Quick Pitch Presenters and Poster Presenters can find more information below specific to their presentation format.
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 Francisco. Unfortunately, we cannot accommodate virtual presentations. If you are unable to attend for any reason, please decline your role and reach out to the Annual Meeting team for assistance, as needed.
All abstract authors must submit their slides ahead of time. Slides can be submitted virtually through the Speaker Center until Monday, September 22, 2025, 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 22, at 11:59 p.m. Pacific time, you may upload directly in the Speaker Ready Room, in Room 102/103. 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 Thursday, August 28, 2025. 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 with instructions to forward three to four summary slides and a take-home message in PowerPoint by Thursday, August 28, 2025. 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 sessions are labeled as “QP 01, QP 02,” and are 60-minutes in length. 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.

Nearly 1,700 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 Francisco, and through the Annual Meeting Portal 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 (September 27 – October 1, 2025). 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.

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.
