Instructions to Authors of Hematology


You were asked to provide a written update of new information and concepts within your assigned area of expertise. Hematology 2022 is not intended as an exhaustive or comprehensive review. Information that is readily available in current hematology textbooks, especially lengthy descriptions of clinical presentations or historical treatments, should not be included in your manuscript. Where appropriate, a personalized approach to important clinical problems ("How I treat...") should be included. This may be included within the text, or set off as a text box or shown in a figure or a flow chart.

We request that manuscripts be case-based. Please lead off your manuscript with a brief clinical case (denote this section with the subhead “Clinical Case”), which highlights one or more of the key clinical questions that you will address in the manuscript. Please come back to the case at least once at the end of the manuscript to provide follow-up and answer the key question(s). You may elect to come back to the case multiple times within the manuscript to address multiple questions. You may also have the patient’s clinical course evolve to highlight additional questions. For example, in a manuscript on the treatment of ITP, you might start out with a case of a patient with newly diagnosed ITP who requires first-line rescue therapy. You may subsequently come back to the case three months later after the patient has proven refractory to first-line therapy and requires second-line maintenance therapy.

Hematology 2022 is a peer-reviewed collection of articles that is indexed in PubMed and many other sources; the book and articles are published online at ashpublications.org/hematology in a permanent archive. The Hematology periodical is frequently accessed online and very highly regarded by your peers. ASH offers two tests (one malignant; the other non-malignant) to align with Hematology chapters, for a total of 40 CME credits.


Please limit the main text of your manuscript to no more than 2,500 words and no more than 40 references; in general, the references should include work that has been published within the past five years. Please also include a minimum of four and no more than eight tables or figures, including a visual abstract (see below), which should be an original figure (not a duplication or slight variation of one of the manuscript figures). Figures and tables do not count against the 2,500-word limit.


Include a short, unstructured abstract (150–250 words). It will appear with your article and will be indexed in Medline.

Visual Abstract

Authors are responsible for creating your own original visual abstract that summarizes the main message(s) of your manuscript. The visual abstract counts toward the requirement for 4-8 tables and figures. The visual abstract should be original and not duplication or slight variation of one of the manuscript figures. If you have any questions, you may contact [email protected].

Learning Objectives

Include at least two learning objectives based on the content of your manuscript. Use a strong action verb to describe what process or outcome the audience will learn as a result of reading your manuscript.


The manuscript title must match your presentation title exactly. Do not include the name of the session in the title but be sure to include the name of the disease so that the title can stand alone. For example, “Optimal use of PET imaging in high-risk disease” is not sufficiently specific. The title of the presentation and manuscript should be “Optimal use of PET imaging in high-risk lymphoma.”


Manuscripts are to be authored by the speaker. If more than one co-author is listed, the speaker must be either first or last author. All authors will be required to complete a copyright transfer form upon manuscript acceptance.


Format the references using the style in Blood, as follows:

Melo JV, Gordon DE, Cross NC, et al. The ABL-BCR fusion gene is expressed in chronic myeloid leukemia. Blood. 1993;81(1):158-165.

For complete instructions on reference style, refer to ashpublications.org/blood/pages/references. Personal communications, unpublished observations, manuscripts submitted but not yet accepted for publication, or papers “in preparation” must appear parenthetically in the text. Please submit written permission when citing a personal communication.

Figures and Tables

Optimal specifications: grayscale 600 dpi; color 300 dpi; line drawing 1,200 dpi. Only digital figure, image, and, table files are required. All figures and images are verified. Include proof of permission for all previously published figures, images, and, tables that are under copyright law by a publisher.

Reprint Permission

You will need to obtain written permission from any respective copyright owners for the use of any textual, illustrative, or tabular materials that have been previously published or are otherwise copyrighted and owned by third parties. Contact the original publisher for written permission to reprint and display (in print and all electronic formats available now and in the future); ASH will pay any fees charged for permissions. Please keep a copy of the permission(s) for your records.


You will receive manuscript submission instructions with a link to the online submission site in April.

Review Process

Hematology 2022 is a peer-reviewed publication. Your paper will be reviewed by one of the publication’s editors, the session chair, and one outside peer reviewer. You will receive the editor’s opinion along with the reviewers’ comments for your revision and response. You will also have an opportunity to review later copyedited page proofs and answer additional queries prior to publication.


Inquiries regarding your manuscript should be directed to [email protected].
