Aim. Comparative effi cacy analysis of autologous hematopoietic stem cells (HSC) prior to auto-HSCT in patients with lymphoproliferative disorders (LPDs) and multiple sclerosis (MS). Materials & Methods. The trial included 237 patients: 103 LPD and 134 MS patients. In 225 patients HSC mobilization involved only colony-stimulating factors (CSFs), in 12 patients chemotherapy (cyclophosphamide, etoposide) was combined with CSFs. On the intended date of cytapheresis all the patients were tested for CD34+ marker expression. Сytapheresis followed in the patients with CD34+ count more than 0.01 × 106/mL. Results. In 23 (22 %) LPD patients CD34+ count was too low for auto-HSCT (‘collection failure group’). Within this group 19 patients received CSF mobilization, and 4 patients received chemotherapy + CSF. Plerixafor was administered in 5 patients, in 4 of them a repeated mobilization also failed to collect enough cells. In 80 LPD patients the number of mobilized and collected CD34+ cells was suffi cient for auto-HSCT (‘collection success group’). Within this group 77 patients received auto-HSCT, 74 patients were treated with CSF mobilization, 6 patients received chemotherapy + CSF, and in 11 patients plerixafor was administered. Median total number of CD34+ cells in the ‘collection success group’ was 2.7 × 106/kg. All 134 MS patients had enough CD34+ cells for auto-HSCT. All of them received CSF mobilization. Median total number of CD34+ cells in the MS group was 2.34 × 106/kg. Potential risk factors for HSC mobilization failure in LPDs were evaluated. They included age, gender, prior radiotherapy, number of antitumor treatment lines prior to auto-HSCT, clinical response prior to auto-HSCT (complete/partial remission or stabilization), and HSC mobilization regimen. These factors with the exception of gender were not associated with mobilization failure parameters. The worst mobilization outcomes were reported in male patients. 52 О.В. Федык и др. КЛИНИЧЕСКАЯ ОНКОГЕМАТОЛОГИЯ аутоТГСК (полная, частичная ремиссия или стабилизация), режим мобилизации ГСК. Перечисленные факторы, кроме пола пациентов, не отнесены к параметрам «неудачной» мобилизации. Худшие показатели мобилизации отмечались у лиц мужского пола. Заключение. У 22 % больных ЛПЗ не удалось реализовать план лечения, включавший высокодозную химиотерапию и аутоТГСК, вследствие недостаточного количества аутологичных клеток CD34+ в продукте афереза. Возможным прогностическим фактором «неудачной» мобилизации при ЛПЗ может служить мужской пол пациента.

Сравнительный анализ эффективности мобилизации и коллекции аутологичных гемопоэтических стволовых клеток крови у пациентов с лимфопролиферативными заболеваниями и рассеянным склерозом. Клиническая онкогематология. 2019;12(1):51–8. DOI: 10.21320/2500-2139-2019-12-1-51-58 Conclusion. In 22 % of LPD patients the planned high-dose chemotherapy and auto-HSCT failed due to insuffi cient counts of autologous CD34+ cells in apheresis product. Male gender can be considered to be a prognostic factor of mobilization failure in LPDs.
