High cure rate with a moderately intensive treatment regimen in non-high-risk childhood acute lymphoblastic leukemia. Results of protocol ALL VI from the Dutch Childhood Leukemia Study Group.

Abstract

For children with non-high-risk ALL, the combination of IV medium high-dose methotrexate (2 g/m2 times three), triple intrathecal therapy in the first year of maintenance treatment, and the use of dexamethasone for induction and pulses during maintenance treatment has proved to be highly effective, especially in the prevention of CNS relapse. A high cure rate was achieved without the use of anthracyclines, alkylating agents, and cranial irradiation.
