Summary
The ALL SCTped 2012 FORUM is a multinational, multi-centre, controlled, prospective phase III study for the therapy and therapy optimisation for children and adolescents with ALL in complete morphological remission (CR, less than 5% bone marrow blasts, no blasts in cerebrospinal fluid, no other extramedullary leukemia), who have an indication for HSCT with a myeloablative conditioning regimen. The stratification of patients in first and following remissions according to the individual transplantation modalities rests upon an indication for allogeneic HSCT and the availability of a suitable donor within the individual transplantation groups.
