The XIX International Workshop on CLL will now be fully virtual in 2021.

The iwCLL organizing committee has made this decision out of an abundance of caution for everyone’s health and safety.

While this change was unexpected, and we regret the loss of the opportunity to connect with you in person, we hope to view this as an opportunity to innovate. The committee is diligently working on an interactive and engaging agenda. The iwCLL biennial international conference continues to be committed to advancing the field of chronic lymphocytic leukemia (CLL) and related lymphoproliferative disorders through thought-provoking discussions, debates, and virtual networking.

Please continue to check back on the website for updates. We hope that you will be able to join us in this new virtual format, even if you were not originally planning to make the trip to Krakow.
