The IWWM-11’s primary concern is the health and safety of those involved in our activities. Given the massive and worldwide impact of the COVID-19 crisis, the Workshop Scientific and Chair Committees have decided to reschedule the 11th International Workshop on Waldenstrom’s macroglobulinemia (IWWM-11), in Madrid, Spain, to October 5-8, 2022.

Our sympathy and respect goes out to all involved in fighting the COVID-19 crisis. We urge all of you to stay safe and to regularly visit our special COVID-19 Hematology Hub for the latest updates.

The 11th International Workshop for Waldenstrom's Macroglobulinemia is being held October 5-8, 2022 in Madrid, Spain. The venue chosen for this meeting is one of Madrid’s premier hotels, Westin Palace Madrid, situated in the Las Letras quarter. The hotel nestles in one of the city’s most historic areas linking the city’s most enriching museums, Prado, Reina Sofia and Thyssen-Bornemisza, vibrant parks and gardens, and epicurean eateries. Instructions for registration and check-in will be provided as we get closer to the newly rescheduled dates.

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. IWWM-11 will continue to support future research by including a Junior Investigator Poster presentation event with short oral presentations. Instructions for Abstract submissions for poster presentations will be announced at a later date..


Opening Ceremonies will take place on (date TBD) in the Neptuno room of the Westin Palace Madrid. The ceremony will feature the presentation of the R. Kyle Award and evening lectures.

The Closing Ceremonies will take place on (date TBD) at one of the prestigious art museums in Madrid. The ceremony will feature the presentation of the Waldenstrom Award and evening lectures.

We expect this international Workshop to be as comprehensive as IWWM-10, which included 15 sessions with over 60 technical presentations. Since the IWWM began in 2000, the number of participating international investigators has steadily grown to over 30 countries, and over 6,500 publications including those created and developed from the IWWM Workshops. These publications have been published in the New England Journal of Medicine, Blood, Clinical Lymphoma Myeloma, Haematologica, Journal of Clinical Oncology, Leukemia, Nature, and other top publications.

IWWM-11 will continue the mission to enrich each attendee’s understanding and help foster discoveries and collaborations leading to more effective treatments and ultimately find a cure for Waldenstroms macroglobulinemia.
