Scientific Meetings

The AACR marshals the full spectrum of expertise of the cancer community to accelerate progress in the prevention, biology, diagnosis, and treatment of cancer by annually convening more than 30 conferences and educational workshops, the largest of which is the AACR Annual Meeting with more than 74,000 attendees for the 2020 virtual meetings and more than 22,500 attendees for past in-person meetings.

Details for select upcoming meetings are below:


The American Association for Cancer Research (AACR), the National Cancer Institute (NCI), and the European Organisation for Research and Treatment of Cancer (EORTC) will host their annual International Conference on Molecular Targets and Cancer Therapeutics Oct. 7-11, 2021. The Molecular Targets and Cancer Therapeutics conference is one of the premier international meetings featuring novel cancer therapeutics. It will bring together scientists, academics, and pharmaceutical industry representatives from leading cancer research organizations around the world to discuss and collaborate on innovations in drug development, target selection, and the impacts of new and recent discoveries in molecular biology.

Embargo policy

Abstract titles and authors will be posted on the AACR website on September 30. Once the titles and authors are posted, a curtain-raiser press release may be issued as long as it does not contain any data.

Abstracts will be posted to the meeting platform when the meeting begins on October 7 at 9 a.m. ET. Any information in the abstract may be disclosed at that time. If there is additional information in the presentation that is not in the abstract, that information is embargoed until the beginning of the session where the study will be presented.

AACR Annual Meeting

The AACR Annual Meeting program covers the latest discoveries across the spectrum of cancer research—from population science and prevention; to cancer biology, translational, and clinical studies; to survivorship and advocacy—and highlights the work of the best minds in research and medicine from institutions all over the world.

The American Association for Cancer Research (AACR) hosted Week 1 of its two-week virtual Annual Meeting on April 10-15, 2021. Week 1 featured the Opening Ceremony, plenary sessions, major scientific sessions, and award lectures. All proffered abstracts that were accepted for presentation—including clinical trials and late-breaking abstracts—were presented that week. Week 2, which ran from May 17-21, featured education sessions, methods workshops, meet the expert sessions, and professional advancement sessions.
