В обзоре рассматриваются отдельные вопросы режимов мобилизации и режимов кондиционирования, а также проведения аутологичной трансплантации гемопоэтических стволовых клеток (аутоТГСК) у больных с множественной миеломой. Цель-определить на этой основе новые научные направления по повышению эффективности аутоТГСК. Ключевые слова: множественная миелома, аутологичная трансплантация гемопоэтических стволовых клеток, режим мобилизации, режим кондиционирования.

Aim. To establish correlation between CD34+ autologous hematopoietic stem cell (HSC) count and colony-forming units (CFU) in the same peripheral blood apheresis product samples before and after cryopreservation in multiple myeloma and lymphoma patients, and to assess clinical value of these parameters. Materials & Methods. Cell samples of peripheral blood cyta-pheresis product and cell cultures were studied before and after cryopreservation in 32 multiple myeloma and 25 lymphoma patients who underwent autologous HSC transplantation. The material was analyzed using culture technique and flow cytometry. Results. The paper provides information on the relationship between CD34+ HSC count obtained by flow cytometry, and CFU in cell culture obtained by cytapheresis of the same peripheral blood samples. A direct correlation was confirmed between CD34+ count and all the CFUs before and after cryopreservation in lymphoma patients. Correlation between CD34+ count and granulocyte-macrophage CFUs was revealed in multiple myeloma and lymphoma patients before cryopreservation. Conclusion. The parameter of colony-forming capacity used for the assessment of the functional HSC was shown to be equally reliable criterion for condition evaluation of autotransplant proliferative pool than CD34+ cells. Both methods should be applied for qualitative and quantitative evaluation of an autotransplant for multiple myeloma and lymphoma patients.
