Source of stem cells impacts on hematopoietic recovery after high-dose chemotherapy

Abstract

The restoration of hematopoiesis after high-dose chemotherapy may be accelerated by the use of stem cells from the bone marrow (BM) or peripheral blood. Numerous reports utilizing mobilized peripheral blood progenitor cells (PBPC) for stem cell rescue have shown that PBPC are sufficient to restore hematopoiesis, but there are little data comparing the recovery among patients treated with various stem cell sources. We reviewed the clinical outcomes of 69 women at our institution who were treated for locally advanced or metastatic breast cancer with high-dose cyclophosphamide (CY) and thiotepa and autologous stem cell and growth factor support. Of the 43 patients with normal BM, 19 received BM alone and 24 received BM plus G-CSF mobilized PBPC. Of the 26 patients with evidence of metastatic disease in the BM, or evidence of fibrosis and hypocellularity, 15 received CY-mobilized PBPC and 11 received CY/G-CSF-mobilized PBPC. Of the marrow-negative patients, those receiving BM alone had significantly longer (P < 0.001) granulocyte recovery (absolute neutrophil count > 500 x 10(6)/l) and platelet recovery (platelets > 50 x 10(9)/l) compared with BM + G-CSF-mobilized PBPC. They also had significantly longer (P < 0.001) durations of an...Continue Reading

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.
