NCIt definition : Administration of high doses of chemotherapy or radiation therapy, as well as immunosuppressive
therapy, to a transplant recipient prior to a bone marrow or hematopoietic stem cell
transplant. Conditioning destroys the patient's abnormal blood cells or cancer, as
well as slows the patient's immune response against the donor bone marrow (graft rejection).;
Alternative definition : NCI-GLOSS: The treatments used to prepare a patient for stem cell transplantation
(a procedure in which a person receives blood stem cells, which make any type of blood
cell). A conditioning regimen may include chemotherapy, monoclonal antibody therapy,
and radiation to the entire body. It helps make room in the patient's bone marrow
for new blood stem cells to grow, helps prevent the patient's body from rejecting
the transplanted cells, and helps kill any cancer cells that are in the body.;
