It is my great pleasure to welcome you all to the the 12th I-BFM Biennial Childhood Leukemia and Lymphoma Symposium (CLLS). We are very glad to have our traditional meeting hosted for the first time in Spain, in Valencia. We will be in a special country, and I am sure it will be a special meeting!
Since the beginning, we thought to have the CLLS meeting as an important opportunity for fellows, researchers and junior faculty to highlight novel basic and clinical information on malignant hematological malignancies. The keynote topics of this conference are acute lymphoblastic leukemia (ALL), translational research in ALL and lymphoma, immunotherapy and targeted agents in leukemia and lymphoma, myeloid disorders, therapy and outcome of leukemia and lymphoma in low- and middle-income countries, optimal supportive care in malignant hematologic malignancies, amongst others...



  • Biology and Translational Research of Primary and Relapsed/Refractory Acute Leukemias and Lymphomas
  • Therapy and Outcome of Acute Leukemias and Lymphomas in Low- and Middle-Income Countries
  • Myelodysplastic and Myeloproliferative Disorders
  • Cellular Therapies of Acute Leukemias and Lymphomas 
  • Optimal Supportive Care in Leukemia and Lymphoma
