Abstract

Mobilized PBPs are an acceptable alternative to ABMT for hematopoietic rescue following high-dose therapy (table 10-3). Platelet recovery appears to be faster following PBPs than ABMT. In most series, leukocyte recovery is also accelerated, but this may be particularly due to the use of colony-stimulating factor. Morbidity and mortality also appear to be reduced. The optimal mobilization methodology is not defined, but larger numbers of PBPs are mobilized by chemotherapy plus colony-stimulating factors compared to CSFs alone, at the cost of enhanced toxicity. The use of PBPs has also facilitated the study of very-high-intensity regimens in which multiple courses of high-dose chemotherapy are given at very short intervals. Following completion of feasibility studies, prospective random assignment trials will be necessary to determine the benefit, if any, of this approach.

Blood And Marrow Transplantation

The use of hematopoietic stem cell transplantation or blood and marrow transplantation (bmt) is on the increase worldwide. BMT is used to replace damaged or destroyed bone marrow with healthy bone marrow stem cells. Here is the latest research on bone and marrow transplantation.

Allogenic & Autologous Therapies

Allogenic therapies are generated in large batches from unrelated donor tissues such as bone marrow. In contrast, autologous therapies are manufactures as a single lot from the patient being treated. Here is the latest research on allogenic and autologous therapies.
