The Use of Stem Cell Mobilization for the Treatment of Blood Related Cancers

Autologous hematopoietic stem cell transplantation (aHSCT) is a well-established treatment for hematologic malignancies such as multiple myeloma (MM) and non-Hodgkin lymphoma (NHL). [1,2] Various changes in the field over the past decade, including the frequent use of tandem aHSCT in MM, the advent of novel therapies for the treatment of MM and NHL, plus the addition of new stem cell mobilization techniques, have led to the need to reassess current stem cell mobilization strategies.

Mobilization failures with traditional strategies are common and result in delays in treatment and increased cost and resource utilization. The mobilization of hematopoietic stem cells fails in approximately 20% of patients with MM and up to 40% of patients with NHL.[3,4] Poor mobilization can lead to poor engraftment, increased morbidity, greater resource utilization, and increased costs.[4,5] The cause of poor mobilization can be partially explained by clinical variables (i.e., age, underlying disease, prior therapies, underlying marrow function) and cannot be predicted.[6] 

Methods to increase the circulating concentrations of hematopoietic stem cells (HSCs) have been found to be necessary to ensure adequate and successful collections. Novel mobilization regimens have changed the climate of stem cell transplantation such aHSCT may now be performed in more than 90% of those patients in whom the procedure is indicated, with a minimal need for remobilization strategies. The precise regimen that is most effective remains to be determined, however, and may vary depending on patient population and the specific goal of stem cell collection. [7,8]
