Reduced Intensity Conditioning
Includes patients receiving a second or greater allogeneic hematopoietic stem cell transplant (HSCT) using reduced intensity conditioning (RIC). Patients will receive busulfan, fludarabine, total body irradiation and stem cell transplant. Keppra will be given for seizure prophylaxis.
0.4 mg/kg (0.5 mg/kg if <4 years of age) intravenously (IV) every 6 hours on Days -8 and -7.
Other Name: Busulfex
40 mg/m^2 intravenously (IV) over 1 hour on days -6 through -2.
Other Name: Fludara
Radiation: Total body irradiation
200 cGy on Day -1
Biological: Stem cell transplant
stem cell infusion on day 0
Keppra will be given for seizure prophylaxis during busulfan administration as per the standard institutional protocol.
Other Name: Levetiracetam
- Time to Engraftment [ Time Frame: Day 42 ]Neutrophil engraftment is defined as the first day of three consecutive days where the neutrophil count (absolute neutrophil count) is 500 cells/mm3 (0.5 x 109/L) or greater.
- Incidence of Graft Failure [ Time Frame: Day 42 ]Graft failure is defined as not accepting donated cells. The donated cells do not make the new white blood cells, red blood cells and platelets.
- Status of Donor Chimerism [ Time Frame: Day 100, 6 Months, 1 Year ]A state in bone marrow transplantation in which donor hematopoietic cells and host cells exist compatibly without signs of rejection.
- Incidence of Acute Graft-Versus-Host Disease (GVHD) [ Time Frame: Day 100 ]Acute Graft-Versus-Host Disease is a severe short-term complication created by infusion of donor cells into a foreign host.
- Change in Incidence of Chronic Graft-Versus-Host Disease (GVHD) [ Time Frame: 6 Months, 1 Year ]Chronic Graft-Versus-Host Disease is a severe long-term complication created by infusion of donor cells into a foreign host.
- Incidence of Transplant Related Mortality [ Time Frame: 6 Months ]In the field of transplantation, toxicity is high and all deaths without previous relapse or progression are usually considered as related to transplantation.
- Incidence of Overall Survival [ Time Frame: 6 Months ]
The percentage of people in a study or treatment group who are alive for a certain period of time after they were diagnosed with or treated for a disease. Also called survival rate.
Overall survival will be defined as time from date of enrollment to date of death or censored at the date of last documented contact for patients still alive.
