Induction Intensification in Treating Infants With Newly Diagnosed Acute Lymphoblastic Leukemia

This study has been completed.

Last verified: February 2014

RATIONALE: Drugs used in chemotherapy work in different ways to stop cancer cells from dividing so they stop growing or die. Combining more than one chemotherapy drug and giving them as induction intensification may kill more cancer cells.

PURPOSE: This phase II trial is studying how well induction intensification works in treating infants with newly diagnosed acute lymphocytic leukemia.

Further study details as provided by Children's Oncology Group:

Primary Outcome Measures:
  • Feasibility of intensification
  • Event-free survival
  • Comparison of event-free survival rates in infants with and without leukemic blasts translocations

Secondary Outcome Measures:
  • Correlation of minimal residual disease at completion of induction, beginning of continuation, and at completion of therapy with patient outcome
  • Clinical prognostic features associated with outcome
  • Correlation of biologic characteristics of leukemia cells at diagnosis with outcome
  • Patterns of gene expression
