ABSTRACT
Prognosis for children treated according to the BFM-90m protocol (Berlin-Frankfurt-Munster Group) for acute lymphoblastic leukemia (ALL) improved significantly as compared with previous modalities. Methotrexate was used in the dose of 1,000 mg/m2, 36 h. The paper presents the 10-year results for this modification. Patients aged 0-15 years were treated at hematological hospitals of Moscow, other Russian towns and in Minsk, Belarus, (July 5, 1990-November 11, 2000). BFM-90m treatment was given to 682 children out of 1,326 with primary diagnosis of ALL; a comparative trial of the MB-91 protocol hed been carried out at the same clinics since 1991. During 10 years, recurrence-free survival was 72% while overall survival--77%. Toxicity of side-effects was tolerable. The BFM-90m treatment showed significantly better results in both countries.
