About SOHO

The Society of Hematologic Oncology (SOHO) was established as a non-profit corporation in 2012 with aims to promote worldwide research, education, prevention, clinical studies and optimal patient care in all aspects of hematologic malignancies and related disorders. Since that time, over 7,000 members from 110 countries have joined the society from around the globe.

SOHO is a global society designed specifically for clinicians, research scientists and related health care professionals who specialize in the research and treatment of patients with hematologic malignancies. SOHO’s mission is to expedite worldwide research and education through the exchange of scientific information. Organized by its founders and world class committees, SOHO is the only international society specific to this field.

Society Mission Statement

The Society of Hematologic Oncology (SOHO) was established as a non-profit corporation in 2012 with aims to promote worldwide research, education, prevention, clinical studies and optimal patient care in all aspects of hematologic malignancies and related disorders. The mission of the Society is: “to expedite the discovery and application of knowledge of the Biology, Therapy, Etiology and Prevention of the Hematologic Malignancies. These findings should provide a platform for the progress needed for ‘Cancer Control’.”

To read more about the founding of the Society, see the Commentary written by Founding President Emil J Freireich, MD.

Society Structure

SOHO is led by a Board of Directors with ten voting members. In addition, an outstanding group of clinician-scientists have been assembled to serve on the Steering Committee to provide guidance and direction in the continued development of SOHO.

Two additional committees, Scientific and Education, are responsible for abstract review and the scientific program of the annual meetings, respectively. A third committee, Publication, is responsible for identifying opportunities for publishing work derived from the Society's activities. In addition, members of the Publication Committee manage the publication of papers for the society's featured article series, "SOHO State of the Art and Next Questions." Members of these groups are listed on the 'Committees' webpage.

Annual Meeting

The SOHO annual meeting has no parallel general sessions so that delegates may attend all sessions in sequential order. In addition, presentations are limited to the ‘latest advances’ allowing all topics to be covered in only 3.5 days. Last year, more than 2,500 hematologic oncology experts gathered from around the world to share the latest clinical research impacting patient treatment at the hybrid 11th Annual Meeting of the Society of Hematologic Oncology. 

The eleventh annual meeting of the society, SOHO 2023, was held as a hybrid event (in-person AND virtual) on September 6-9, 2023. Advances in leukemia, lymphoma, myeloma, myeloproliferative neoplasms, myelodysplastic syndromes and related malignancies was highlighted during the official educational program.
