Dear Friends and Colleagues,

As you are all aware of, due to the Coronavirus (COVID-19) pandemic, we had to postpone the 12th Biennial Childhood Leukemia and Lymphoma Symposium (CLLS) to 2021. Due to the uncertainty on how the pandemic will develop and its continuing threat, we have decided to hold the Symposium as a full virtual meeting on 11–12 March 2021. So please continue to hold these on your calendar. We hope that as many of you as possible could take part at the virtual meeting and that together we will still make it a special event.

Should you require any further information, please do not hesitate to contact us at info@clls2021.org
Stay safe! With our best wishes!
Andishe Attarbaschi and Andrea Biondi
