What was measured

Relapse is defined as post-transplant disease recurrence in participants who had initially recovered or improved, with incidence measured from Day 0 to 1 year post-transplant, and from 1 year post-transplant to 2 years post-transplant. Monitoring will take place separately for the single and double UCBT cohorts.

Analysis population: Analysis population is all patients who underwent UCB transplant on study.

Groups in this outcome

Regimen A: High-dose TBI + Fludarabine + Cyclophosphamide; Single-cord Transplant

Patients receive myeloablative conditioning comprising fludarabine IV over 30 minutes on days -8 to -6, cyclophosphamide IV on days -7 and -6, and undergo high-dose TBI BID on days -4 to -1. Patients then undergo single-unit UCBT on day 0. Fludarabine: Given IV Cyclophosphamide: Given IV Total-Body Irradiation: Undergo high-dose TBI Umbilical Cord Blood Transplantation: Undergo UCBT Patients receive GVHD prophylaxis comprising cyclosporine IV over 1 hour every 8 or 12 hours, then cyclosporine PO (if tolerated), on days -3 to 100 with taper on day 101. Patients also receive mycophenolate mofetil IV every 8 hours on days 0 to 7 and then PO (if tolerated) TID on days 8-30. Mycophenolate mofetil is tapered to BID on day 30 or 7 days after engraftment if there is no acute GVHD, and then tapered over 2-3 weeks beginning on day 45 (or 15 days after engraftment if engraftment occurred \> day 30) after engraftment if there continues to be no evidence of acute GVHD. Cyclosporine: Given IV and PO Mycophenolate Mofetil: Given IV and PO Laboratory Biomarker Analysis: Correlative studies

Regimen B: Middle-intensity TBI + Fludarabine + Cyclophosphamide + Thiotepa; Single-cord Transplant

Patients receive myeloablative conditioning comprising fludarabine IV over 30-60 minutes on days -6 to -2, cyclophosphamide IV on day -6, thiotepa IV over 2-4 hours on days -5 and -4, and middle-intensity TBI QD on days -2 and -1. Patients then undergo single-unit UCBT on day 0. Fludarabine: Given IV Cyclophosphamide: Given IV Thiotepa: Given IV Total-Body Irradiation: Undergo moderate-intensity TBI Umbilical Cord Blood Transplantation: Undergo UCBT Patients receive GVHD prophylaxis comprising cyclosporine IV over 1 hour every 8 or 12 hours, then cyclosporine PO (if tolerated), on days -3 to 100 with taper on day 101. Patients also receive mycophenolate mofetil IV every 8 hours on days 0 to 7 and then PO (if tolerated) TID on days 8-30. Mycophenolate mofetil is tapered to BID on day 30 or 7 days after engraftment if there is no acute GVHD, and then tapered over 2-3 weeks beginning on day 45 (or 15 days after engraftment if engraftment occurred \> day 30) after engraftment if there continues to be no evidence of acute GVHD. Cyclosporine: Given IV and PO Mycophenolate Mofetil: Given IV and PO Laboratory Biomarker Analysis: Correlative studies

Regimen A: High-dose TBI + Fludarabine + Cyclophosphamide; Double-cord Transplant

Patients receive myeloablative conditioning comprising fludarabine IV over 30 minutes on days -8 to -6, cyclophosphamide IV on days -7 and -6, and undergo high-dose TBI BID on days -4 to -1. Patients then undergo double-unit UCBT on day 0. Fludarabine: Given IV Cyclophosphamide: Given IV Total-Body Irradiation: Undergo high-dose TBI Umbilical Cord Blood Transplantation: Undergo UCBT Patients receive GVHD prophylaxis comprising cyclosporine IV over 1 hour every 8 or 12 hours, then cyclosporine PO (if tolerated), on days -3 to 100 with taper on day 101. Patients also receive mycophenolate mofetil IV every 8 hours on days 0 to 7 and then PO (if tolerated) TID on days 8-30. Mycophenolate mofetil is tapered to BID on day 30 or 7 days after engraftment if there is no acute GVHD, and then tapered over 2-3 weeks beginning on day 45 (or 15 days after engraftment if engraftment occurred \> day 30) after engraftment if there continues to be no evidence of acute GVHD. Cyclosporine: Given IV and PO Mycophenolate Mofetil: Given IV and PO Laboratory Biomarker Analysis: Correlative studies

Regimen B: Middle-intensity TBI + Fludarabine + Cyclophosphamide + Thiotepa; Double-cord Transplant

Patients receive myeloablative conditioning comprising fludarabine IV over 30-60 minutes on days -6 to -2, cyclophosphamide IV on day -6, thiotepa IV over 2-4 hours on days -5 and -4, and middle-intensity TBI QD on days -2 and -1. Patients then undergo double-unit UCBT on day 0. Fludarabine: Given IV Cyclophosphamide: Given IV Thiotepa: Given IV Total-Body Irradiation: Undergo moderate-intensity TBI Umbilical Cord Blood Transplantation: Undergo UCBT Patients receive GVHD prophylaxis comprising cyclosporine IV over 1 hour every 8 or 12 hours, then cyclosporine PO (if tolerated), on days -3 to 100 with taper on day 101. Patients also receive mycophenolate mofetil IV every 8 hours on days 0 to 7 and then PO (if tolerated) TID on days 8-30. Mycophenolate mofetil is tapered to BID on day 30 or 7 days after engraftment if there is no acute GVHD, and then tapered over 2-3 weeks beginning on day 45 (or 15 days after engraftment if engraftment occurred \> day 30) after engraftment if there continues to be no evidence of acute GVHD.
