Dear abstract authors,

We are very pleased you are interested in submitting your research abstract to the 2024 American Society of Hematology meeting -- the premier global meeting in hematology -- being held in San Diego, California, December 7 - 10, 2024. Before you begin the process, I would like to highlight several changes in our abstract format and in abstract categories and give you more information regarding requirements for presentation of abstracts at the annual meeting. Your close attention is necessary to give your abstract the best chance for inclusion in the annual meeting as an oral session presentation or poster.

  • Abstracts will be limited to 3,800 characters to be accommodated on our digital platform.
  • In contrast to previous years, figures and tables are not permitted.

Please carefully review all category descriptions before selecting a category for your abstract. Categories are updated every year to respond to submission trends and to encompass new topics. This year, updates have been made to multiple category descriptions with significant changes including the renumbering of categories (particularly those in the 600 and 900 groupings), discontinuation of two categories (731. Autologous Transplantation, and 705. Cellular Immunotherapies: Commercial and Late Stage), addition of several new categories (909. Education, Communication, and Workforce, 628. Aggressive Lymphomas: Cellular Therapies, and 655. Multiple Myeloma: Cellular therapies), and splitting of several categories (including several in thrombosis and homeostasis, clinical lymphomas, and health services, quality improvement and outcomes research).

ASH reserves the right to move your abstract to a more appropriate category if misplacement is noted by the Secretary during abstract processing; however, correct categorization at the time of submission is the author's responsibility and will ensure the highest quality review process.

The 66th ASH Annual Meeting of the American Society of Hematology (ASH) will be held Saturday, December 7, through Tuesday, December 10, 2024, in San Diego, California. The meeting will be in person, with a virtual attendance option, however, presenting authors are expected to be on-site San Diego. If the first author is unable to attend in person, another abstract author able to attend in person may be substituted as the presenter. We realize decisions about attendance may not be feasible before the abstract submission deadline and we will accommodate changes as necessary. ASH is committed to providing a safe and healthy environment for all attendees and continually monitors the state of the COVID-19 pandemic. We encourage you to monitor this page to stay abreast of any updates to the health and safety information for the 66th ASH Annual Meeting in San Diego, California.

  • Poster presenters will be required to submit pre-recorded presentations and PDFs of their posters by November 12th.
  • ASH reminds authors that the last date to withdraw abstracts from the annual meeting is September 18, 2024.
