[Results and problems in the treatment of childhood leukaemia (author's transl)]. / Ergebnisse und Probleme bei der Behandlung der kindlichen Leukämien in Ungarn.

391 children received complex chemotherapy according to uniform treatment schedules, proposed by the Hungarian Study Group for Childhood Leukaemia, which was established in 1971. Survival among the patients showed an increasing tendency: more than 50% of patients with ALL are stille alive 3 years after the beginning of treatment. One patient is in complete remission 9 3/4 years after the establishment of the diagnosis. Two types of maintenance therapy were investigated among the patients entered for this study in 1974. "Pulses" with Vincristine-Prednisolone every second month were found to be more optimal than monthly "pulses".
