Early and treatment-related deaths in childhood acute myeloid leukaemia in the Nordic countries: 1984-2003

Abstract Despite major improvements in the cure rate of childhood acute myeloid leukaemia (AML), 5-15% of patients still die from treatment-related complications. In a historical prospective cohort study, we analyzed frequency, clinical features and risk factors for early deaths (ED) and treatment-r...

Description
Summary:Abstract Despite major improvements in the cure rate of childhood acute myeloid leukaemia (AML), 5-15% of patients still die from treatment-related complications. In a historical prospective cohort study, we analyzed frequency, clinical features and risk factors for early deaths (ED) and treatment-related deaths (TRD) in 525 children included in the Nordic protocols NOPHO-AML-84, -88 and -93. Seventy patients (13%) died before starting treatment or from treatment-related complications. The death rate rose from 11% in NOPHO-AML-84 to 29% in -88, but then fell to 8% in -93. Sixteen patients (3%) died within the first two weeks, mainly from bleeding or leukostasis. Hyperleukocytosis, age <2 or >10 years were risk factors. After day 15, 10% of patients died from treatment-related complications with infection as the main cause of death. Risk factors were age <2 or >10 years and treatment according to the NOPHO-AML-88 protocol. The number of EDs and TRDs in AML is high. Therefore optimal antifungal prophylaxis is essential, and studies on the benefit of antibacterial prophylaxis and individual risk factors for ED and TRD are needed. : NO MORE UNTIL JAN 2005 (Hasle, Henrik) lene.molgaard@dadlnet.dk (Molgaard-Hansen, Lene) merja.mottonen@ppshp.fi (Mottonen, Merja) heidi.glosli@rikshospitalet.no (Glosli, Heidi) gudmkj@talnet.is (Jonmundsson, Gu?mundur K.) jonas.abrahamsson@vgregion.se (Abrahamsson, Jonas) hasle@dadlnet.dk (Hasle, Henrik) Aarhus University Hospital Skejby, Department of Paediatrics - Aarhus - DENMARK (Molgaard-Hansen, Lene) University Hospital, Oulu, Department of Paediatrics - Oulu - FINLAND (Mottonen, Merja) Oslo University Hospital, Rikshospitalet, Department of Paediatrics - Oslo - NORWAY (Glosli, Heidi) Landspitalinn University Hospital, Reykjavik, Department of Paediatrics - Reykjavik - ICELAND (Jonmundsson, Gu?mundur K.)
