What was measured

Disease Free Probability where DFS time is defined as time from randomization end of induction to first event (relapse, second malignant neoplasm, death) or date of last contact for patients who are event-free.

Analysis population: Includes only T-cell Acute Lymphoblastic Leukemia (T-ALL) patients randomized to Nelarabine versus No Nelarabine. T-LLY patients are excluded from this analysis. Induction failures non-randomly assigned to Arm IV were excluded from this analysis.
