2020 ASTRO Annual Meeting

Late-breaking Abstracts

October 25-28, 2020
Miami Beach Convention Center
Miami Beach, Florida

Late-breaking abstract submission site opens: Friday, July 24, 2020
Late-breaking abstract submission site closes: Sunday, August 9, 2020, at 11:59 p.m. Pacific time

Original research abstracts will be selected for late-breaking presentations based on scientific merit, timeliness and interest to ASTRO’s membership and attendees. A special panel of peer reviewers will review the late-breaking abstracts using the highest standards.

Abstracts should only be submitted as late-breaking abstracts if they meet the following criteria:

  • The research is limited to highly significant and timely findings in clinical oncology, radiobiology or medical physics that were not available during the February 24, 2020, submission process.
  • Only abstracts that are deemed to be of high scientific priority and that merit presentation in the Plenary, Clinical Trials or the special Late-breaking Abstract session will be accepted.
  • Late-breaking abstracts cannot be a revision of an abstract submitted during the February 24, 2020, submission process.
  • Late-breaking abstracts must not have been submitted, presented, accepted for presentation or published in any other scientific venue.
  • Standards for accepting late-breaking abstracts for presentation are much higher than those required for abstracts accepted for the general scientific sessions.

Red Journal, PRO and Advances in Radiation Oncology

Authors of accepted abstracts are encouraged to submit a full manuscript for review and consideration for publication in one of ASTRO’s official journals, the International Journal of Radiation Oncology•Biology•Physics (Red Journal), Practical Radiation Oncology (PRO) or Advances in Radiation Oncology. Please contact the editorial office at 703-502-1550 or visit www.redjournal.orgwww.practicalradonc.org or www.advancesradonc.org if you have questions regarding manuscript submission.

Embargo Policy and Press Program Policy

All abstracts submitted to 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 media professionals may result in suspension of credentials at the ASTRO Annual Meeting as well as future meetings and may also impact the ability to receive advance media materials for future meetings. Embargo violations by abstract authors and/or sponsors may result in removal of the abstract from the scientific program. Abstract authors are responsible for notifying financial and other sponsors about this embargo policy.

Questions about the embargo policy may be directed to ASTRO’s media relations team.

The full text of the abstracts selected for oral and poster presentation will be available online at the start of ASTRO's Annual Meeting. Abstracts also will be published in a supplement of the International Journal of Radiation Oncology•Biology•Physics (www.redjournal.org).


You will be notified via email of the disposition of your late-breaking abstract in late July 2019. Acceptance of the abstract by the committee obligates the author to present the paper and pay the meeting registration fee. If circumstances prevent attendance, you must notify ASTRO of your withdrawal and arrange for an alternate presenter, preferably a co-author. Late-breaking abstracts will be published online and in the International Journal of Radiation Oncology•Biology•Physics, www.redjournal.org. They will also be made available at the Annual Meeting on ASTROmobile and ASTRO's website.
