Intervention: methotrexate
Description: methotrexate 15 mg/m2 IV on day +1 (do not give until 24 hours after marrow infusion), and 10mg/mg2 IV on days +3 and +6.~Methotrexate may be held after two doses for bilirubin .2 mg/dL. If serum creatinine is \>2x baseline, methotrexate will be omitted. If the presence of ascites or pleural effusion, methotrexate will be omitted.

Group type: ACTIVE_COMPARATOR
Intervention: Mesna
Description: Dosing per institutional preference for hemorrhagic cystitis. Mesna 300 mg/m2 as a 15 minute infusion prior to each dose of cyclophosphamide, then at 3,6,9,12, 18 and 21 hours after initiation of each cyclophosphamide infusion. Alternative method of Mesna administration is 10 mg/kg prior to cyclophosphamide and 100 mg/kg/24 hours by continuous infusion.

Group type: ACTIVE_COMPARATOR
Intervention: Radiation
Description: Central Nervous System (CNS) therapy:~a) CNS Leukemia prior to study entry: No TBI i) No prior CNS irradiation: 2340 centigray (cGy) in 13 fractions of 180 cGy to the cranial field and 600 cGy in 200 cGy fractions to the spinal field prior to conditioning. II) \>/= 1800 cGy prior CNS irradiation: 1800 cGy to cranial field and 600 cGy spinal prior to conditioning. If prior radiation therapy (RT) doses \>3000 cGy have been administered or CNS Leukemia prior to study entry: TBI, consult with Principal Investigator (PI). Recommend: 1) no prior CNS irradiation: 600 cGy in 3 fractions to the cranial field prior to conditioning or overlapping with TBI.~Testicular Boost Irradiation: a) overt testicular leukemia at relapse: No TBI 2400 cGy in 12 fractions prior to conditioning; b) overt testicular leukemia at relapse: TBI 1200 cGy in 6 fractions over 8-10 days prior to conditioning. c) No overt testicular leukemia: 200 cGy first and last fractions of TBI-
