20 consecutive adult patients with acute lymphoblastic leukemia were treated with an intense induction regimen including vincristine, doxorubicin, prednisolone, L-asparaginase and cyclophosphamide. 16 patients (80%) achieved complete remission and were then given CNS prophylaxis and 3 years of maintenance therapy. With minimum follow-up of 24 months, the median duration of first remission is 37+ months. Out of 10 patients who have completed maintenance therapy, 2 have relapsed after 14 and 22 months, respectively, and 7 are in continuous complete remission 1+-55+ months off therapy.

Complex clinical, neurological and psychological examination was carried out in 23 children with acute lymphoblastic leukemia (ALL), being in complete initial remission from 5 to 12 years and without medication following the successful intensive therapy according to the protocol 0171 from 2 1/2 to 9 years. Somatic deficiency was observed in 2 children. Slightly hypoplastic bone marrow haemopoesis was found in 2 children. All children had normal haemogram. In 7 children lowered values of E-rosettes and in 3 children lowered levels of serum IgA were detected. Two children were HBsAg positive, in one of them with mild fibrosis was found at biopsy. Pathological neurological findings occurred in 7 children; pathological electromyogram (EMG) and electroencephalogram (EEG) in 8 and 5 children, respectively. Deviations of intellectual development were observed in 13 children. Deviations found can be connected in particular with long-term antileukemic therapy, especially with neurotoxic effects of some components of therapeutic regimen used (methotrexate, brain irradiation).
