Rapid progression of multiple myeloma following G-CSF mobilization

Abstract

A 23-year-old man diagnosed as having multiple myeloma was treated with melphalan and prednisone monthly. After six cycles, an autologous peripheral blood stem cell transplantation (ABSCT) was planned. Peripheral blood mononuclear cells were collected after G-CSF mobilization (5 micrograms/kg/day for 5 days). Ten days after the last dose of G-CSF the patient showed a striking progression of multiple myeloma. A 57% infiltration of plasma cells in bone marrow and recurrence of laboratory abnormalities were evident. The patient's clinical course strongly suggests that myeloma progression was triggered by G-CSF and supports the concept of G-CSF mediated autocrine stimulation of myeloma growth.

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.
