What was measured

Bone marrow MRD status is defined as negative with \< 0.1 detectable leukemia cells.

Analysis population: Group "Prednisone and High Dose MTX (non-random)" who either had EFS/OS events occur before 5 years or did not have minimum 5 years of follow-up.

Groups in this outcome

Dexamethasone and Capizzi Methotrexate Patients < 10 Years

Patients receive intrathecal cytarabine (Age-based dosing: Age (yrs) Dose 1 - 1.99 30 mg 2 - 2.99 50 mg ≥ 3 70 mg) on day 1; infusions of vincristine sulfate 1.5 mg/m2/dose (maximum dose of 2 mg) on Days 1, 8, 15 and 22 and daunorubicin hydrochloride (25 mg/m2/dose on Days 1, 8, 15 and 22. Dexamethasone (5 mg/m2/dose on Days 1-14 by mouth or infusion twice a day in weeks 1 and 2; intrathecal methotrexate (Aged based dosing: Age (yrs) Dose 1 - 1.99 8 mg 2 - 2.99 10 mg 3 - 8.99 12 mg ≥ 9 15 mg) on days 8 and 29 (CNS3 also on days 15 \& 22) and an injection of pegaspargase (2500 International units/m2 x 1 dose on Day 4, 5 or 6).

Dexamethasone, High Dose Methotrexate (Non Randomly Assigned)

Patients non-randomly assigned to the DH regimen based on one (or more) of the following characteristics: (1) CNS3 status at entry, (2) testicular leukemic involvement at entry, or (3) extensive pre-treatment with steroids prior to entry. Patients receive intrathecal cytarabine (Age-based dosing: Age (yrs) Dose 1 - 1.99 30 mg 2 - 2.99 50 mg ≥ 3 70 mg) on day 1; infusions of vincristine sulfate 1.5 mg/m2/dose (maximum dose of 2 mg) on Days 1, 8, 15 and 22 and daunorubicin hydrochloride (25 mg/m2/dose on Days 1, 8, 15 and 22.
