Bone marrow and blood cells as alternative sources of hematopoietic progenitors after failure of a first collection. A single institution retrospective study

Abstract

From October 1992 through October 1994, we retrospectively identified 12 patients who underwent two collections of hematopoietic progenitors because the first one was considered inadequate. Five patients had bone marrow harvest first and underwent apheresis later. Seven patients underwent apheresis first and had bone marrow harvest later. Most patients had advanced cancer and had been heavily pretreated at time of harvesting. The second harvest yielded an appropriate number of progenitors for a proportion of patients. Nine of 12 patients received both cryopreserved marrow and blood cells. Hematopoietic recovery in these patients was somewhat longer than in patients currently receiving blood cells as a support for high dose chemotherapy at our institution; however, except for 2 patient, neutrophil and platelet recovery was observed within a reasonable delay. We conclude that patients who have poor blood cell collection may benefit from bone marrow harvesting, and vice versa.

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.
