  Purpose

RATIONALE: Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Combining more than one drug may kill more cancer cells. It is not yet known which regimen of combination chemotherapy is more effective for childhood acute lymphoblastic leukemia.

PURPOSE: This randomized phase III trial is comparing different regimens of combination chemotherapy to see how well they work in treating children with acute lymphoblastic leukemia.

Primary Outcome Measures:
  • Event-free survival [ Time Frame: 4 years ] [ Designated as safety issue: No ]
    The test statistic will compare Kaplan-Meier curves with sample size derived from a modification of the Makuch-Simon method for historical controls

  • Occurrence of anticipated failures [ Time Frame: Up to 7 years ] [ Designated as safety issue: No ]
    An O'Brien-Fleming analysis will be conducted, with significance declared if the observed logrank Z-statistic exceeds the z/sqrt(IF), where IF=fraction of anticipated failures that have occurred and z=critical value of the final analysis.

  • Grade 3 or greater CNS toxicity rates assessed using NCI CTC version 2.0 [ Time Frame: Up to 7 years ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:
  • Measures of laboratory factors (other than MRD) [ Time Frame: Up to 7 years ] [ Designated as safety issue: No ]
    Cox multiple regression will be utilized.

  • Homocysteine levels [ Time Frame: Up to 7 years ] [ Designated as safety issue: No ]
    Will be correlated to acute neurotoxicity by Cox regression.
