The GRAALL Intergroup (LALA, GOELAL, SAKK) has been created in 2003. It includes all French and Swiss Hematology centers dealing with adult patients with acute lymphoblastic leukemia (ALL), as well as a part of Belgian centers. One important feature of the GRAALL Intergroup is the continuous development of functional links between clinical, translational and more basic research teams working in the ALL field, based on centralised biological characterisation and bio banking.
