Abstract
Two groups of children with refractory acute lymphoblastic leukemia were treated with a regimen of methotrexate (MTX) and asparaginase (Asn'ase) based on studies of the effect of MTX in vitro on human lymphoblasts exposed to Asn'ase. Induction therapy in 12 children produced 4 complete remissions, 3 partial remissions, and 5 failures. Responsiveness to Asn'ase seemed necessary for successful induction with the drug combinations. Maintenance therapy in 18 children produced a median hematologic remission of 31 weeks (range 3-85 weeks). During remission, 2 children developed central nervous system leukemia and 2 died of infection. The mean maximally tolerated dose of MTX was 361 mg/m2. The results of this trial suggest therapeutic synergy in maintenance therapy and the capability of Asn'ase to attenuate MTX toxicity.Entities:
