Summary

With this protocol the ALL-SZT BFM international study group wants

to evaluate whether hematopoietic stem cell transplantation (HSCT) from matched family or unrelated matched donors (MD) is equivalent to the HSCT from matched sibling donors (MSD).

to evaluate the efficacy of haematopoietic stem cell transplantation (HSCT) from mismatched family or unrelated mismatched donors (MMD) as compared to HSCT from matched sibling donor (MSD) and matched donor (MD).

to determine whether therapy has been carried out according to the main haematopoietic stem cell transplantation (HSCT) protocol recommendations. The standardisation of the treatment options during haematopoietic stem cell transplantation (HSCT) from different donor types aims at the achievement of an optimal comparison of survival after HSCT with survival after chemotherapy only.

to prospectively evaluate and compare the incidence of acute and chronic graft- versus-host-disease (GvHD) after haematopoietic stem cell transplantation (HSCT) from matched sibling donor (MSD), from matched donor (MD) and from mismatched donor (MMD).

Additional Information

Official title Allogeneic Stem Cell Transplantation in Children and Adolescents With Acute Lymphoblastic Leukaemia
Description Patients with high risk or relapsed acute lymphoblastic leukaemia (ALL) have a worse prognosis compared to all other patients with ALL. For these patients additional therapy approaches are required after they have achieved remission with multimodal chemotherapy. Allogeneic haematopoetic stem cell transplantation shows promising results mainly due to an immunological antileukaemic control by the graft-versus-leukaemia effect, but treatment related mortality and morbidity remains a serious problem.
