Which children do benefit from bone marrow transplant? The EBMT Paediatric Diseases Working Party.
The development of chemotherapy in childhood ALL has been the leader of the success story of paediatric oncology. At least 2/3 of the children can be cured nowadays at the first attempt of treatment. From the remaining again 1/3 can be treated successfully for the relapse of their disease with conventional therapeutic strategies. This means, however, that there is no chance for cure with chemotherapy alone for 20 to 25% of the children. BMT has been shown for a long time to be an alternative therapy especially in those cases in which conventional chemotherapy fails. In spite of the fact that many children with ALL have been transplanted during recent years there is still no general agreement on the question which children need BMT. However a few statements can be made: The value of ABMT in ALL is probably not better than that of chemotherapy alone. In 1st CR a group of children can be defined, which might benefit from BMT. In 2nd CR the value of chemotherapy depends very much from the duration of 1st remission. Allogeneic BMT is the only chance for cure in very early relapses, superior to chemotherapy in early and late relapses and possibly equal to chemotherapy in very late relapses. The paper tries to summarise our current knowledge about the situation.
