    Abstract:
    An analysis of clinical and laboratory parameters and the results of treatment of 14 children with Down Syndrome and acute leukaemia was performed. The children were treated between 1986-1997. Their age ranged from 1 day to 13 years (average 5.5). There were 9 girls and 5 boys. Four of them had congenital heart disease. ALL was observed in 10, AML in 3 and TAM (Transient Abnormal Myelopoesis) in 1. Half of the children with ALL was classified as L1 according to FAB with the majority of common phenotypes and M6 in ANLL group. Remission was achieved in all ALL patients, six of them are still free of symptoms, the remaining four died of brain haemorrhage as a consequence of myelosuppression. Only 1 of 3 children with ANLL achieved remission. The child died of cardiac arrest after induction phase of BFM 95 programme (ADE). The 2 remaining children with ANLL also died of circulation failure before initiation of chemotherapy. The children had complicated cyanotic heart disease. The neonate with TAM is in clinical and hematological remission. In conclusion all children with ALL achieved hematological remission but tolerance of treatment was a problem. The majority of patients had diminished bone marrow reserve. Mortality was frequently related to circulatory failure in children with associated heart defects. It seems necessary to discuss the modification of accepted programmes for leukemia for the treatment of children with Down Syndrome.
