Abstract

To explore the efficacy and safety of high-dose of etoposide with granulocyte colony-stimulating factor (G-CSF) for mobilization of peripheral blood stem cells, 10 patients with hematologic malignancies including 6 patients with multiple myeloma and 4 with non Hodgkin' s lymphoma received an etoposide dose of 1.6 g/m2. The total dose of undiluted etoposide was given on day 1 as a continuous intravenous infusion via a central vein for 10 hours. G-CSF 5 microg/kg was used on day 3 and given daily subcutaneously until leukopheresis was completed. The results showed that leukopheresis was started at days 11 (range 9-13 days) following etoposide therapy, the mean number of CD34+ cells collected in all 10 patients was 9.4 x 10(6)/kg (range 4.2 - 17.3 x 10(6)/kg), by an average of 2.6 leukophereses (range 1-4) times. Mobilization procedure that produced yields of greater than 4.0 x 10(6)/kg were achieved in every patient. Toxicity showed oropharyngeal mucositis, faucitis and urethritis respectively in 3 patients. It is concluded that high-dose etoposide with G-CSF is an effective and safe mobilizing regimen for autologous peripheral blood stem progenitor cells in patients with hematologic malignancies.

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.

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.
