Results of mobilization, apheresis and autoreinfusion of hematopoietic stem cells in children with neuroblastoma: role of monitoring the count of CD34+ cells in peripheral blood

Autologous hematopoietic stem cell transplantation (auto-HSCT) is a standard for the treatment of oncological, hematologic, and also some immune diseases, ensuring the restoration of blood counts after high-dose chemotherapy. In children, the success of mobilization and collection of hematopoietic stem cells (HSCs) is especially important. Mobilization schemes for children are decided on an individual basis, which requires the development and implementation of recommendations for improving the efficiency of mobilization and collection of HSCs. Mobilization schemes include the use of granulocyte colony-stimulating factor in the form of monotherapy or in combination with CXCR4 antagonists. These schemes are ineffective in some children, which requires re-mobilization or rejection of transplantation, which negatively affects the prognosis. When preparing a patient for HSCs collection, it is necessary to take into account all previous therapy, the patient’s age, weight and height indicators, and general somatic state. Harvesting the required amount of HSCs will allow for high-dose therapy followed by auto-HSCT, and thereby increase the effectiveness of treatment. It is necessary to optimize the protocol for mobilization of HSCs with a large bias for pediatric patients, which will clearly define the criteria for mobilization, give indications for this procedure and determine the criteria for technical collection, which will allow to obtain the optimal number of CD34+ cells, which will ensure the success of the treatment.
