Abstract

Peripheral blood hematopoietic progenitor cells (PBHC) are the standard source of support for high-dose chemotherapy because of faster recovery of marrow function. Unfortunately, a proportion of patients are unable to mobilize adequate progenitors to proceed to autologous hematopoietic cell transplant (AHCT). Granulocyte-CSF-stimulated BM-derived hematopoietic progenitor cells (BMHC) may circumvent this problem. From 1999 to 2006, 52 patients (cases) with AML, Hodgkin (HL) or non-Hodgkin's lymphoma (NHL) in whom PBHC mobilization failed underwent a G-CSF-stimulated bone marrow harvest and proceeded to AHCT. Their outcome was compared with 422 patients (controls) with AML, HL and NHL undergoing AHCT using only PBHC. Twenty-three patients received BMHC alone and 29 patients received a combination of PBHC and BMHC. Median engraftment time for neutrophils (>0.5 x 10(9)/l) and platelets (>20 x 10(9)/l) were 14 and 27 days, but significantly longer when compared with controls (11 days, 11 days, P<0.0001). Patients receiving both PBHC and BMHC had faster engraftment, when compared with those receiving BMHC alone (P<0.001). In conclusion, performing an AHCT using G-CSF-stimulated BMHC in patients failing PBHC collection is feasible wit...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.

B-Cell Lymphoma

B-cell lymphomas include lymphomas that affect B cells. This subtype of cancer accounts for over 80% of non-Hodgkin lymphomas in the US. Here is the latest research.
