Important Message - Date Change

Dear Colleagues:

It is with great sorrow that we watch the coronavirus epidemic continue to impact lives across the globe. Over 500,000 of our fellow human beings have lost their lives to COVID-19, as both the death toll and number of coronavirus cases continues to grow. Here in the United States, the coronavirus cases have greatly increased with much strain on the medical system for many of our states.  In addition, there have been many travel restrictions imposed for travel to/from the United States, and many other countries around the globe in response to the COVID-19 pandemic. Our recognition at this time is that it will not be possible to hold the IWWM-11 this year given the large safety concerns and travel restrictions.

Our initial intent was to move the workshop planned for this October in Madrid to 2022. We have succeeded in making this adjustment and have re-booked the WM workshop for the Westin Madrid for October 27 - 29, 2022. Our website has been adjusted to reflect this postponement. Our local chairs, Professors Ramon Garcia-Sanz and Jesus San Miguel have been very supportive of this adjustment, and we look forward to working with them on the program and being in Madrid in 2022.

We are also giving consideration at this time for a smaller WM workshop to be held next summer in Boston. This workshop would permit a smaller group  of 40  persons to safely attend to discuss emerging data for WM and help in the development of WM treatment guidelines.  While we thought this might have been possible for this Fall, the new realities of the COVID-19 crisis, and the feedback from many of our scientific advisors favored a live, but smaller meeting next year.

We will inform you of the details of the revised workshops once they become available. We thank you for all hard work and efforts on behalf of WM patients.

11th International Workshop on Waldenström’s Macroglobulinemia

Westin Palace Madrid, Madrid, Spain
October 27-29, 2022


Attend the world’s most comprehensive hematology/oncology event on Waldenstrom’s macroglobulinemia; the 11th International Workshop on Waldenstrom’s macroglobulinemia (IWWM-11).

The 11th International Workshop for Waldenstrom's Macroglobulinemia is being held October 27th through the 29th, 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. Onsite registration and check-in begin at 14:00 (2:00pm) on Wednesday, October 26th, conference sessions starting on Thursday, the 27th, at 8:00am.

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. Abstract submissions for poster presentations will begin in June 2022.

Opening Ceremonies will take place on Thursday, October 27th 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 Saturday, October 29th, 2022 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.

We look forward to welcoming you to the Workshop!
