What was measured

Disease-free survival defined as time from randomization end of induction to first event (relapse, second malignant neoplasm, remission death) or date of last contact for those who are event-free.

Analysis population: Includes only T-cell Acute Lymphoblastic Leukemia (T-ALL) patients randomized to Capizzi Methotrexate (CMTX) versus High-Dose Methotrexate (HDMTX). CNS3 patients non-randomly assigned to HDMTX (Arms III and IV) and Induction failures non-randomly assigned to Arm IV were excluded. T-LLY patients are excluded.
