preparative regimen

High doses of cancer chemotherapy and/or radiation therapy, used prior to bone marrow or cord blood transplantation to eliminate the recipient's blood-forming cells. Very high doses of drugs and/or radiation are used to eliminate as many diseased cells from the recipient's marrow as possible. As a result, the recipient's normal blood cells are also destroyed. Preparative regimens temporarily make patients immunodeficient, anemic, and platelet–deficient. Immunocompetence and the ability to form red cells and platelets are restored to patients when the donated stem cells they receive engraft, i.e., begin to repopulate and reproduce in the marrow. Also known as conditioning regimen.

The tolerability of RIC makes it an attractive preparative regimen for allo-HSCT, but the reduced dose or omission of cyclophosphamide, busulfan, and total body irradiation (TBI) raised concerns regarding the immunosuppressive and tumor-ablative potency.

Several studies documented that reduced intensity preparative regimen followed by stem cell infusion was associated with mixed chimerism and then full chimerism with a documented graft vs leukemia (GVL) effect in the setting of hematologic malignancies and graft versus tumor (GVT) effect in the setting of solid tumors (26-32).

"For the majority of unrelated transplants following a standard high-dose preparative regimen, bone marrow should be used since survival is equivalent with two sources but the incidence of chronic graft-versus-host disease, which can be a debilitating complication, is significantly less with marrow," Dr.

Before the injection, patients undergo an immunodepleting preparative regimen to eliminate competing T regulatory cells and lymphocytes.

The incidence of HC varies considerably according to the preparative regimen, the preventative measures employed and perhaps the incidence of GVHD.

All recipients received the standard preparative regimen involving cyclophosphamide (60 mg∙kg [sup]-1∙d [sup]-1 x 2, day −4, day −3) and total body irradiation (TBI) (5 Gy/day x 2, day −2, day −1).

Busulfan is a myeloablative agent that is used in combination with cyclophosphamide as a preparative regimen for bone marrow transplantation; high-dose busulfan can be used as a substitute for total body irradiation.

The strengths of this study include looking at the kinetics of chimerism and not at just one point of time chimerism and a cohort of adult patients with only myeloid malignancies treated at a single center by the same physicians with uniform peripheral blood stem cell grafts and the widely used Bu based myeloablative preparative regimens with the standard-of-care methotrexate/tacrolimus-based with or without antithymocyte globulin GVHD prophylaxis.

Moreover, HCT preparative regimens used for AA are associated with unacceptable organ toxicity in DC patients, whereas newer, disease-specific preparative regimens of reduced intensity have yielded improved outcomes.
