Dear Friends and Colleagues

Happy New Year 2024!

We would like to take this opportunity to inform you about changes that have been made to the date and venue for the 12th International Workshop on Waldenstrom’s Macroglobulinemia (IWWM-12). As you undoubtedly know, on October 7, 2023, Hamas launched a horrific attack on the people of Israel prompting an ongoing war which will likely continue for months to come.

Therefore, with great sadness, we have opted to change plans for IWWM-12 which was to be held in Jerusalem. We do so with heavy heart knowing how important this workshop was to so many in our WM community and to the local physicians and scientists in Israel who have contributed much to our understanding and treatment of WM. We want to assure our Co-Chairs Drs. Moshe Gatt (Hadassah Medical Center, Israel) and Merav Leiba (Ben-Gurion University of the Negev, Israel), that one day soon IWWM will be held in Israel, and to thank them for their efforts in the extensive preparations that were already undertaken. In response, our Workshop Secretariat Chris Patterson and I have sought the guidance of many of our WM global thought leaders and prior IWWM chairs. We proposed several venues based on availability, and have selected Prague, Czech Republic as the new venue for IWWM-12.

We look forward to welcoming you to Prague. Please feel free to reach out for any questions or additional details.

Sincerely yours,

12th International Workshop on Waldenström’s Macroglobulinemia

Prague Marriott Hotel

Prague, Czech Republic
October 17-19, 2024

 The 12th International Workshop on Waldenstrom’s Macroglobulinemia (IWWM-12) is scheduled to take place from October 17th to October 19th, 2024, in Prague, Czech Republic. The conference will be held at the Prague Marriott Hotel, one of Prague’s premier hotels located in the old city of Prague. The hotel is situated in one of the city’s most historic areas, surrounded by enriching museums, vibrant parks and gardens, and epicurean eateries.

The welcome reception will be held on Wednesday, October 16th, 2024, at the Prague Marriott Hotel. The Opening Ceremonies will take place on Thursday, October 17th, 2024, at the inspiring National Museum, and the Closing Ceremonies will be held on Saturday, October 19th, 2024, on board the Grand Bohemia-Prague Boats.

These venues promise to provide an in-depth appreciation of Czech history, architecture, food, and culture, and provide an exciting backdrop for the Jan Gosta Waldenstrom, Robert A. Kyle, and the Peter S. Bing Humanitarian Awards. Drs. Christian Buske (University of Ulm, Germany) and Jeffrey Matous (Colorado Blood Institute, USA) will be serving as Co-Chairs for this workshop.

On Friday, October 18th, 2024, the IWWM-12 will continue to support future WM research by sponsoring the Junior Investigator Poster presentation event along with the Young Investigator Awards. The top eight abstracts highly scored will have a separate plenary session in the program. With appreciation from the IWWM, the International Waldenstrom’s Macroglobulinemia Foundation (IWMF) has generously gifted the top 20 Young Investigator Awards (YIAs) payment for registration fees, travel, and lodging. Abstract submissions for poster presentations will open on March 1st, 2024, and close on July 15th, 2024.

The 12th International Workshop on Waldenstrom’s Macroglobulinemia (IWWM-12) is expected to be as comprehensive as IWWM-11, which included twenty sessions with over ninety technical presentations. Since the IWWM began in 2000, the number of participating international investigators has steadily grown to over thirty countries, and over 8,700 publications including those created and developed from the IWWM Workshops. These publications have been published in top publications such as the New England Journal of Medicine, Blood, Clinical Lymphoma Myeloma, Haematologica, Journal of Clinical Oncology, Leukemia, Nature, Lancet, and Seminars of Hematology 1.

The Workshop’s mission is to further the understanding, diagnosis, treatment, and prevention of disorders affecting the blood, bone marrow, and the immunologic system by promoting targeted research, clinical care methods, education, training, and advocacy for Waldenstrom’s macroglobulinemia. The goal is to enrich each attendee’s understanding and help foster research discoveries and lifetime collaborations leading to more effective treatments and ultimately find a cure for Waldenstrom’s macroglobulinemia.

We are excited to welcome you to the 2024 Workshop!
