[Results of treatment of acute leukemia in children using intensive therapy programs]

The authors report the results of the treatment according to the programs BFM-ALL-90 and BFM-AML-83 and 87. A total of 110 children with acute lymphoblastic leukemia (ALL) and 35 with acute myeloblastic leukemia (AML) were treated with remission rate 94.5% and 74.5%, respectively. Under programmed treatment of ALL the recurrences occurred in 12.2% against 46% of the cases in nonprogrammed treatment. 2-year survival made up 75% and 47.3%, respectively. Among AML cases there were frequently prognostically unfavorable ones and patients with neuroleukemia this dictating the necessity of the treatment intensification and irradiation of the skull in AML. Improvement of adjuvant therapy is a must in advance of acute leukemia treatment.
