Abstract
INTRODUCTION Pediatric PBSC harvests pose specific challenges during apheresis and a knowledge of the same and variables affecting PBSC collection are very important in planning these procedures. In the present study safety profile of pediatric PBSC procedures and variables influencing the successful collection were analyzed. METHOD Pediatric PBSC harvest data for 3 years was reviewed for donor, procedural and product parameters and any specific challenges faced during the procedures. Successful PBSC collection was defined when CD34 dose obtained was ≥2 × 106 cells/Kg of recipients' body weight. RESULTS 85 PBSC collections performed on 46 children (age range 1.5-15 years) were included. Sixty-two procedures were on autologous donors and 23 on allogenic donors. The median CD34+ cell dose in the PBSC product per procedure was 2.12 × 106 cells/Kg for autologous procedures and 4.6 × 106 cells/Kg for allogenic procedures. Systemic adverse reaction was observed during only one procedure (0.01 %) and was managed conservatively. Successful dose was collected in 52 procedures (61.17 %) and was significantly associated with CD34+ count of more than 19.7/μL, monocyte count of more than 1.65 × 106/μL, allogenic collection and female gender (p = 0.00001, p = 0.011, p = 0.00052, and p = 0.0001, respectively). CONCLUSION PBSC collection is safe in pediatric age groups and pre-procedure CD34 count of ≥20/μL on the day of collection may result in successful collection of stem cell dose. It is important to identify factors associated with failed collection for appropriate counselling and justifying pre-emptive use of stem cell mobilizing agents.

Optimized peripheral blood progenitor cell mobilization for autologous hematopoietic cell transplantation in children with high-risk and refractory malignancies. Pediatr Transplant 2020; 24:e13602.

Abstract
BACKGROUND Autologous hematopoietic stem cell transplantation (aHSCT) using hematopoietic progenitor cells (HPCs) has become an important therapeutic modality for patients with high-risk malignancies. Current literature on standardized method for HPC apheresis in children is sparse and failure rate reported as high as 30%. PATIENTS/METHODS A retrospective study of 125 pediatric patients with high-risk malignancies undergoing aHSCT in Western Australia between 1997 and 2016 was conducted. RESULTS Mobilization was achieved by means of chemotherapy and granulocyte colony-stimulating factor (G-CSF). Patients underwent apheresis the day after CD34+ counts reached ≥20/µL and an additional dose of G-CSF. Peripheral arterial and intravenous lines were inserted in pediatric intensive care unit under local anesthetic and/or sedation, omitting the need for general anesthesia as well as facilitating an uninterrupted apheresis flow. Larger apheresis total blood volumes were processed in patients weighing ≤20 kg. The minimal dose of ≥2 × 106 CD34+ cells/kg was successfully collected in 98.4% of all patients. The optimal dose of 3-5 × 106 CD34+ cells/kg was collected in 96% of patients scheduled for a single aHSCT, 87.5% for tandem, and 100% for triple aHSCT. All HPC collections were completed in one apheresis session. Mobilization after ≤3 chemotherapy cycles and cycles including cyclophosphamide resulted in a significantly higher yield of CD34+ cells. CONCLUSION Our approach to HPC mobilization by means of chemotherapy and single myeloid growth factor combined with optimal collection timing facilitated by continuous apheresis flow resulted in highly effective HPC harvest in children and adolescents with high-risk cancers.

Abstract
Selected patients with certain hematological malignancies and solid tumors have the potential to achieve long-term survival with autologous hematopoietic progenitor cell transplant. The collection of these cells in peripheral blood avoids multiple bone marrow aspirations, results in faster engraftment and allows treatment of patients with infection, fibrosis, or bone marrow hypocellularity. However, for the procedure to be successful, it is essential to mobilize a sufficient number of progenitor cells from the bone marrow into the blood circulation. Therefore, a group of Brazilian experts met in order to develop recommendations for mobilization strategies adapted to the reality of the Brazilian national health system, which could help minimize the risk of failure, reduce toxicity and improve the allocation of financial resources.

Abstract
Fifty-six aphaereses were performed in 23 pediatric patients with malignant hematological and solid tumors, following three different protocols for PBPC mobilization and distributed as follows: A: seventeen mobilized with 4 g/m2 of cyclophosphamide (CFA) and 10 μg/kg/day of granulocyte colony stimulating factor (G-CSF), B: nineteen with CFA + G-CSF, and C: twenty only with G-CSF when the WBC count exceeded 10 × 109/L. The average number of MNC/kg body weight (BW)/aphaeresis was 0.4 × 108 (0.1–1.4), 2.25 × 108 (0.56–6.28), and 1.02 × 108 (0.34–2.5) whereas the average number of CD34+ cells/kg BW/aphaeresis was 0.18 × 106/kg (0.09–0.34), 1.04 × 106 (0.19–9.3), and 0.59 × 106 (0.17–0.87) and the count of CFU/kg BW/aphaeresis was 1.11 × 105 (0.31–2.12), 1.16 × 105 (0.64–2.97), and 1.12 × 105 (0.3–6.63) in groups A, B, and C, respectively. The collection was better in group B versus group A (p = 0.007 and p = 0.05, resp.) and in group C versus group A (p = 0.08 and p = 0.05, resp.). The collection of PBPCs was more effective in the group mobilized with CFM + G-CSF when the WBC exceeded 10 × 103/μL in terms of MNC and CD34+ cells and there was no toxicity of the chemotherapy.

Abstract
The introduction of plerixafor has enabled successful collection of stem cells in the majority of patients with lymphoma or myeloma in whom previous attempts at mobilization have failed. However, a proportion of patients have been shown to be resistant to this mobilization regimen. To identify the factors that impair stem cell mobilization and collection with plerixafor, we reviewed the data for 197 patients who had undergone mobilization with plerixafor and granulocyte-colony stimulating factor in Central Europe. Predictors of mobilization failure were evaluated using logistic regression analysis. Among the 197 patients mobilized, the target of ≥2.0 × 10(6) CD34+ cells/kg was collected from 133 (67.5%). Our analysis revealed that previous treatment with lenalidomide, bortezomib, melphalan, radiotherapy, or autologous stem cell transplantation and regimen of plerixafor use in combination with chemotherapy had no significant effect on the efficiency of collection. In contrast, an age ≥65 years (odds ratio 0.331, 95% CI: 0.112-0.977, P < 0.05), a diagnosis of non-Hodgkin's lymphoma (odds ratio 0.277, 95% CI: 0.124-0.622, P < 0.01), and treatment with ≥ four chemotherapy regimens (odds ratio 0.366, 95% CI: 0.167-0.799, P < 0.05) were associated significantly with failed mobilization. The rate of successful mobilizations was decreased in patients treated with purine analogues (odds ratio 0.323, 95% CI: 0.096-1.094, P = 0.07) but increased in female patients (odds ratio 1.961, CI: 0.943-4.080, P = 0.07). Patients who are characterized by the above negative features could benefit potentially from further improvement in the mobilization strategy.

Abstract
BACKGROUND Plerixafor (P) reduces mobilization failure rates but it is very expensive. For better utilization of P, we employed a risk-adaptive strategy of using it only in patients who are at high risk of mobilization failure, defined by peripheral blood (PB) CD34+ cell count of fewer than 10×10(6)/L after 4 days of filgrastim (F) alone. STUDY DESIGN AND METHODS Herein, we present the results of efficacy and cost-benefit analysis of this risk-adaptive approach for hematopoietic progenitor cell (HPC) collection. All patients received daily F for 4 days, and P was added for those "at-risk" patients from Day 4 with apheresis commencing the following morning. F and P were continued daily for up to a maximum of 4 days or until more than 5×10(6) CD34+ cells/kg were collected. Forty-two transplant-eligible patients underwent HPC mobilization. RESULTS Eighteen patients mobilized with F alone and 24 patients required P with F. Two patients failed adequate HPC mobilization after F+P. Addition of P increased the PB CD34+ count by 6.8-fold with a mean yield of 4.9×10(6) CD34+ cells/kg. Decision-analysis model estimated cost-effectiveness for this risk-adaptive approach of using P with savings of $19,300/patient. Engraftment after HPC infusion was similar among the patients regardless of mobilization regimens. CONCLUSION These results suggest that addition of P to F based on a risk-adaptive strategy significantly reduces the frequency of mobilization failures and is also cost-effective.

Abstract
Stem cells harvested from peripheral blood are the most commonly used graft source in hematopoietic stem cell transplantation. While G-CSF is the most frequently used agent for stem cell mobilization, the use of G-CSF alone results in suboptimal stem cell yields in a significant proportion of patients undergoing autologous transplantation. Plerixafor (AMD3100, Genzyme Corporation) is a bicyclam molecule that antagonizes the binding of the chemokine stromal cell-derived factor-1 (SDF-1) to its cognate receptor CXCR4. Plerixafor results in the rapid and reversible mobilization of hematopoietic stem cells into the peripheral circulation and is synergistic when combined with G-CSF. In clinical studies of autologous stem cell transplantation, the combination of plerixafor and G-CSF allows the collection of large numbers of stem cells in fewer apheresis sessions and can salvage those who fail G-CSF mobilization alone.

Abstract
BACKGROUND It is often a clinical dilemma to determine when to collect autologous peripheral blood progenitor cells (PBPCs) in patients who received prior chemotherapy. It is also challenging to predict if the collected cells will be enough for one or two transplants. STUDY DESIGN AND METHODS A total of 103 PBPC donors were followed to evaluate factors that predict poor autologous PBPC collection. The donors were categorized into three groups: plasma cell disorders (PCDs), lymphomas, and normal allogeneic donors. RESULTS Our evaluation showed that platelet (PLT) count before growth factor administration significantly correlated with total CD34+ cell yield (Spearman r = 0.38, p < 0.001). Further analysis showed this correlation was only significant in plasma cell disease patients who received prior chemotherapy (Spearman r = 0.5, p = 0.008). Baseline PLT counts did not correlate with PBPC collection yield in untreated PCD, lymphoma, and normal allogeneic donors. In addition, daily PLT count during PBPC harvest correlated with CD34+ cell yield for that day (Spearman r = 0.41, p < 0.001). With a multiple linear regression model (adjusted R(2) = 0.31, AIC = 63.1), it has been determined that the baseline PLT count significantly correlates with total CD34+ cell yield in treated PCD patients. CONCLUSION Baseline PLT count is a sensitive indicator of autologous PBPC mobilization in PCD patients who received prior chemotherapy. This finding may be considered before growth factor administration to determine the optimal period to mobilize treated PCD patients and to predict if enough cells can be collected for one or two transplants.

Abstract
BACKGROUND Peripheral blood progenitor cells (PBPC) collection after high dose chemotherapy can be influenced by several factors. We searched for parameters that may predict the best day to start harvesting of PBPC in order to collect most CD34+ cells with the least number of aphereses. METHODS We studied patients who underwent mobilization chemotherapy for autologous transplantation. The influence of age, sex, diagnosis, number of previous chemotherapy cycles, peripheral blood (PB) counts at day of mobilization (D0), day of neutrophils <1.0 x 10(9) l(-1) and day of nadir and interval between both (delta) on harvesting was investigated. Multivariate linear correlation models were built to predict the best harvesting with principles of parsimony. In patients where sequential CD34+ cell count was performed, the theoretical day of peak was calculated by interpolation in polynomial regression. RESULTS One hundred and thirty four patients entered the analysis: 36 Hodgkin's lymphoma (HL), 65 B-large cell lymphoma (NHL) and 33 multiple myeloma (MM). Day of harvesting correlated with nr CHT, hemoglobin on D0, day of granulocytes <1.0 x 10(9) l(-1), delta and dosis of mobilization therapy. The day of CD34+ peak could be calculated by the formula = (-0.41) x Hemoglobin D0 + (day peripheral CD34+ cells = 10 x 10(6) microl(-1)) x 0.99 + 7.8. This model could explain 81% of the variance of the peak day and was stable by bootstrap resampling. Day of peripheral CD34+ cells = 10 x 10(6) microl(-1) preceded the calculated peak by 3-9 days. CONCLUSIONS Although the day of best collection can be predicted using only sequential PB counts after mobilization chemotherapy, a model of prediction using peripheral CD34+ cell count is important especially for optimizing collection in poor mobilizing patients.

Abstract
Inadequate stem cell mobilization is seen in approximately 25% of patients undergoing autotransplantation for hematologic malignancies. Remobilization strategies include chemotherapy/cytokine combinations or high-dose cytokines alone or in combination. From 1/1997 to 7/2002, we remobilized 86 patients who failed an initial mobilization (median total CD34=0.72 x 10(6)/kg) in sequential cohorts using high-dose G-CSF (32 microg/kg/day) or G-CSF(10 microg/kg/day)+GM-CSF (5 microg/kg/day). No difference in CD34/kg yields were seen (G-CSF alone: 2.2 x 10(6) and G-CSF+GM-CSF 1.6 x 10(6)) in the median 3 aphereses performed (P=0.333). Of the 86, 23 (27%) failed the second mobilization; 14 were remobilized again (yield=1.5 x 10(6) CD34/kg; three aphereses). Of the 86, 93% went to transplant: three progressed, and three had inadequate stem cells. Significant risk factors for a failed remobilization were: number of stem-cell-damaging regimens (P=0.015), time between last chemotherapy and first mobilization (P=0.028), and higher WBC at initiation of first mobilization (P=0.04). High-dose G-CSF (32 microg/kg/day) was more costly @ USD $9,016, vs $5,907 for the G-CSF+GM-CSF combination (P<0.001). Most patients failing an initial mobilization benefit from a cytokine only remobilization. Lower cost G-CSF+GM-CSF is as effective as high-dose G-CSF.

Abstract
Factors affecting progenitor cell mobilisation in patients with non-Hodgkin's lymphoma (NHL) are incompletely understood. We have analysed factors predicting mobilisation failure in 97 consecutive patients with NHL (59 males, 38 females; median age 49 years) who received mobilisation with intermediate-dose CY (4 g/m(2)) followed by G-CSF. The histology included large cell B (N=50), mantle cell (N=16), follicular (N=16) and other NHL (N=15). The disease status was 1CR/PR/primary refractory in 66 patients and >1 CR/PR in 31 patients. The minimum criterion for successful mobilisation was the collection of >or=1.5 x 10(6)/kg CD34(+) cells. In all, 18 patients (19%) failed to reach this threshold. In univariate analysis, premobilisation factors associated with mobilisation failure included BM involvement at the time of diagnosis (P=0.001) or prior to mobilisation (P=0.001) and low platelet count just prior to mobilisation (P=0.001). In multivariate analysis, only BM involvement at diagnosis (P=0.004) and platelet count just prior to mobilisation (P=0.01) were associated with mobilisation failure. A mathematical model based on these two factors and presented in the form of a receiver operating characteristics curve showed a sensitivity of 0.71 and a specificity of 0.77 in the prediction of mobilisation failure. Patients at a high risk of mobilisation failure may benefit from novel approaches.

Abstract
About 10-30% of patients with non-Hodgkin's lymphoma (NHL) intended to receive high-dose therapy are difficult to mobilise. Damage to the stem cell pool caused by previous chemotherapy may be an important factor in predicting progenitor cell mobilisation. We have analysed associations between chemotherapy score and efficiency of progenitor cell mobilisation in 120 consecutive NHL patients mobilised with intermediate-dose cyclophosphamide (4 g/m(2)) plus G-CSF. The original chemotherapy scoring system proposed by Drake et al was applicable in only 27% of our patients and was not predictive for mobilisation outcome. Therefore we made an improved scoring system for previous chemotherapy by adding new drugs. Altogether, 111 patients (93%) could be scored. Our chemotherapy score showed an inverse correlation with the peak blood CD34(+) count measured after the mobilisation (r=-0.214, P=0.024) and with the number of CD34(+) cells collected (r=-0.234, P=0.02). However, in the receiver operating characteristics curve, no threshold value could be detected for chemotherapy score predicting mobilisation failure. Thus, both the original scoring system as well as our more widely applicable scoring system seem to be of limited value in predicting progenitor cell mobilisation in patients with NHL.

Abstract
Few experiences of peripheral blood (PB) hematopoietic stem cell mobilization for autologous transplantation have been reported to date in children with acute leukemia (AL). The five-drug-chemotherapy 'DIAVE' (dexamethazone, idarubicine, cytosine-arabinoside, vincristine, etoposide), followed by G-CSF, previously reported as consolidation, was adopted as a mobilization regimen in 29 children (median age: 8 years, range: 3-21; median weight: 34 kg, range: 15-73) with ALL in second remission (CR2: 21), in CR3 (2) or ANLL in CR1 (6). A median peak of 94 x 10(6) CD34(+)cells/l (range: 10-604) was reached at a median time of 12 days (range: 10-18) after the beginning of the mobilizing regimen, which was well tolerated. A median of 10.9 x 10(6) CD34(+)cells/kg (range: 2.4-56.6) were collected in 25 patients (86%), approaching 40 x 10(6)/l CD34(+) cells in the PB (ALL in CR2: 20/21, in CR3: 0/2; ANLL: 5/6) by means of one (20) or two (5) leukaphereses; a median of 2.5 blood volumes was processed. Patients with ANLL mobilized more cells than patients with ALL; moreover, the shorter the interval between remission and mobilizing therapy, the higher was the yield. The products collected underwent purification, aiming at achieving complete removal of possibly contaminating leukemic cells, in 21 cases; also, unmanipulated aliquots were stored as rescues for all but one patient. All the 23 patients undergoing transplantation engrafted (ANC >0.5 x 10(9)/l) at a median of 12 days. In conclusion, the DIAVE regimen compares favorably with conventional mobilizing regimens, usually containing cyclophosphamide, in terms of low toxicity, collection time predictability, and efficacy, as shown by the high proportion of patients mobilizing, the large amounts of stem cell collected by means of one or two leukaphereses only, and the prompt engraftment after infusion.

Abstract
Hematopoietic stem cell transplantation has been extensively exploited as a therapeutic and research modality and has revolutionized current patient care. At present, more and more medical centers use peripheral blood progenitor cells for transplantation by mobilizing hematopoietic stem cells from bone marrow to peripheral blood because of potential advantages of peripheral blood stem cell transplantation over bone-marrow transplantation. Different effective mobilization regimens have been developed recently with chemotherapeutic agents, hematopoietic growth factors or their combination. This article reviews current developments related to hematopoietic stem cell mobilization including the biology of hematopoietic stem cells, strategies for mobilization, management for mobilization failure, mechanisms of mobilization, and side effects during mobilization. Finally, the Initiation-Amplification-Emigration-Adaptation Model is proposed to help aid understanding of the mechanisms of hematopoietic stem cell mobilization and to stimulate development of novel and optimal mobilization strategies for patient care.
