In 42 children being in the advanced stage of an acute lymphoblastic leukaemia as well in 7 children with lymphosarcoma a total of 83 series of treatment with L-asparaginase were carried out. During the first blastic crisis of acute leukaemia 74% of complete or partial remissions could be obtained by two treatments and 52% by the following ones. The best results were obtained by organ manifestations of acute leukaemia (80% of complete or partial remissions). Less satisfactory results were achieved in treating lymphosarcoma. All remissions were only of a short duration.
