Primary Outcome Measures
NameTimeMethod
Neutrophil EngraftmentDay 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.

Secondary Outcome Measures
NameTimeMethod
Incidence of Graft FailureDay 100

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.

Disease-Free Survival6 Months

the length of time after treatment ends that a patient survives without any signs or symptoms of that cancer or any other type of cancer. In a clinical trial, measuring the disease-free survival is one way to see how well a new treatment works.

Incidence of Transplant-Related Mortality6 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 ChimerismDay 100, 6 Months, 1 Year

a state in bone marrow transplantation in which bone marrow and host cells exist compatibly without signs of graft-versus-host rejection disease.

Incidence of Acute Graft-Versus-Host DiseaseDay 100

Acute Graft-Versus-Host Disease is a severe short-term complication created by infusion of donor cells into a foreign host.

Incidence of Chronic Graft-Versus-Host Disease6 Months and 1 Year

Chronic Graft-Versus-Host Disease is a severe long-term complication created by infusion of donor cells into a foreign host.

Overall Survival6 Months

Overall survival will be defined as time from enrollment to date of death or censored at the date of last documented contact for patients still alive.
