Impact of plerixafor use in the mobilization of blood grafts for autologous hematopoietic cell transplantation. Transfusion 2024; 64:742-750. [PMID: 38407504 DOI: 10.1111/trf.17755] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/02/2023] [Revised: 01/14/2024] [Accepted: 01/22/2024] [Indexed: 02/27/2024]
Abstract
Plerixafor (PLER), a reversible antagonist of the CXC chemokine receptor type 4, has been in clinical use for mobilization of blood grafts for autologous hematopoietic cell transplantation (AHCT) for about 15 years. Initially PLER was investigated in placebo-controlled trials with the granulocyte colony-stimulating factor (G-CSF) filgrastim. It has also been used in combination with chemotherapy plus G-CSF in patients who had failed a previous mobilization attempt or appeared to mobilize poorly with current mobilization (preemptive use). This review summarizes what is known regarding addition of PLER to standard mobilization regimens. PLER increases mobilization of CD34+ cells, decreases the number of apheresis sessions needed to achieve collection targets and increases the proportion of patients who can proceed to AHCT. It appears also to increase the amount of various lymphocyte subsets in the grafts collected. In general, hematologic recovery after AHCT has been comparable to patients mobilized without PLER, although slower platelet recovery has been observed in some studies of patients who mobilize poorly. In phase III studies, long-term outcome has been comparable to patients mobilized without PLER. This also appears to be the case in patients receiving plerixafor for poor or suboptimal mobilization of CD34+ cells. In practice, PLER is safe and has not been shown to increase tumor cell mobilization.

Adverse impact of delay of platelet recovery after autologous hematopoietic cell transplantation for aggressive non-Hodgkin lymphoma and multiple myeloma. Cytotherapy 2023; 25:1212-1219. [PMID: 37354150 DOI: 10.1016/j.jcyt.2023.05.015] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/06/2023] [Revised: 05/12/2023] [Accepted: 05/30/2023] [Indexed: 06/26/2023]
Abstract
BACKGROUND AIMS The prognostic impact of platelet recovery after autologous hematopoietic cell transplantation (AHCT) on clinical outcomes remains to be elucidated. We aimed to clarify the impact of platelet recovery on clinical outcomes, risk factors of delayed platelet recovery and the necessary dose of CD34+ cells for prompt platelet recovery in each patient. METHODS Using a nationwide Japanese registry database, we retrospectively analyzed clinical outcomes of 5222 patients with aggressive non-Hodgkin lymphoma (NHL) or multiple myeloma (MM). RESULTS At a landmark of 28 days after AHCT, a delay of platelet recovery was observed in 1102 patients (21.1%). Prompt platelet recovery was significantly associated with superior overall survival (hazard ratio [HR] 0.32, P < 0.001), progression-free survival (HR 0.48, P < 0.001) and decreased risks of disease progression (HR 0.66, P < 0.001) and non-relapse/non-progression mortality (HR 0.19, P < 0.001). The adverse impacts of a delay of platelet recovery seemed to be more apparent in NHL. In addition to the dose of CD34+ cells/kg, disease status, performance status and the hematopoietic cell transplant-specific comorbidity index in both diseases were associated with platelet recovery. We then stratified the patients into three risk groups according to these factors. For the purpose of achieving 70% platelet recovery by 28 days in NHL, the low-, intermediate- and high-risk groups needed more than 2.0, 3.0 and 4.0 × 106 CD34+ cells/kg, respectively. In MM, the low-risk group needed approximately 1.5 × 106 CD34+ cells/kg, whereas the intermediate- and high-risk groups required 2.0 and 2.5 × 106 CD34+ cells/kg to achieve about 80% platelet recovery by 28 days. CONCLUSIONS A delay of platelet recovery after AHCT was associated with inferior survival outcomes.

Optimizing Treatment for Relapsed/Refractory Classic Hodgkin Lymphoma in the Era of Immunotherapy. Cancers (Basel) 2023; 15:4509. [PMID: 37760478 PMCID: PMC10526852 DOI: 10.3390/cancers15184509] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/30/2023] [Revised: 09/04/2023] [Accepted: 09/08/2023] [Indexed: 09/29/2023] Open
Abstract
Most patients with classic Hodgkin lymphoma (cHL) are cured with combination chemotherapy, but approximately 10-20% will relapse, and another 5-10% will have primary refractory disease. The treatment landscape of relapsed/refractory (R/R) cHL has evolved significantly over the past decade following the approval of brentuximab vedotin (BV), an anti-CD30 antibody-drug conjugate, and the PD-1 inhibitors nivolumab and pembrolizumab. These agents have significantly expanded options for salvage therapy prior to autologous hematopoietic cell transplantation (AHCT), post-transplant maintenance, and treatment of relapse after AHCT, which have led to improved survival in the modern era. In this review, we highlight our approach to the management of R/R cHL in 2023 with a focus on choosing first salvage therapy, post-transplant maintenance, and treatment of relapse after AHCT. We also discuss the management of older adults and transplant-ineligible patients, who require a separate approach. Finally, we review novel immunotherapy approaches in clinical trials, including combinations of PD-1 inhibitors with other immune-activating agents as well as novel antibody-drug conjugates, bispecific antibodies, and cellular immunotherapies. Ongoing studies assessing biomarkers of response to immunotherapy and dynamic biomarkers such as circulating tumor DNA may further inform treatment decisions and enable a more personalized approach in the future.

Autologous hematopoietic cell transplantation versus whole-brain radiotherapy consolidation in primary central nervous system lymphoma: A systematic review and meta-analysis. Hematol Oncol 2023; 41:88-96. [PMID: 36192141 DOI: 10.1002/hon.3083] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/03/2022] [Revised: 08/18/2022] [Accepted: 09/17/2022] [Indexed: 02/03/2023]
Abstract
The management of newly diagnosed primary central nervous system lymphoma (PCNSL) includes administration of high-dose methotrexate based regimens followed by consolidation therapy to minimize the risk of relapse. However, the best consolidation strategy (autologous hematopoietic cell transplant [auto-HCT] vs. whole-brain radiotherapy [WBRT]) is controversial. Hence, we performed a systematic review and meta-analysis of all randomized controlled trials that compared auto-HCT versus WBRT consolidation for patients with PCNSL after first-line treatment.The primary outcome was overall survival (OS), while the secondary outcomes included progression-free survival (PFS), response rates (overall response rate [ORR] and complete remission [CR]), relapse rate, treatment-related mortality (TRM), and neuropsychological adverse events. We performed a pooled analysis of the single-arm studies that incorporated auto-HCT or WBRT consolidation and evaluated neurocognitive outcomes. Only two studies met the inclusion criteria (n = 240). There was no significant difference in OS (HR = 1.50; 95% CI = 0.95-2.36), PFS (HR = 0.99; 95% CI = 0.44-2.22), ORR (RR = 1.48; 95% CI = 0.90-2.44), CR rate (RR = 1.21; 95% CI = 0.90-1.63), relapse rate (RR = 0.46; 95% CI = 0.05-4.28), and TRM (RR = 5.67; 95% CI = 1.01-31.91). The neuropsychological tests to assess neurocognitive domains were different and inconsistently reported in the two studies and therefore we were unable to perform a meta-analysis but provide a descriptive assessment. Both the studies showed a significant decline in the attention/executive function (based on the trail making test A and trail making test B) in those receiving WBRT compared to auto-HCT. We found 9 single-arm phase II studies that reported data on outcomes associated with either auto-HCT (5 studies) or WBRT (4 studies) consolidation. Of these, two studies (n = 43) reported data on neurocognitive decline following auto-HCT consolidation. Pooled proportion of patients with neurocognitive decline in these studies was 6% (95% CI, 0%-17%) for those receiving auto-HCT and there was no heterogeneity between studies (I2 = 0%). Three studies (n = 122) reported data on neurocognitive decline following WBRT consolidation. Pooled proportion of patients with neurocognitive decline in these studies was 43% (95% CI, 11%-78%) for those receiving WBRT and there was high heterogeneity between studies (I2 = 94%). There was significant heterogeneity between subgroups (p = 0.035). The outcomes were not significantly different in patients with PCNSL receiving auto-HCT or WBRT consolidation therapies, however, there is a higher degree of neurocognitive decline associated with WBRT compared to auto-HCT consolidation. The decision to choose a consolidation strategy needs to be individualized based on age, frailty, and co-morbidities.

The role of additional chemotherapy prior to autologous HCT in patients with relapse/refractory DLBCL in partial remission-A retrospective multicenter study. Eur J Haematol 2023; 110:149-156. [PMID: 36251268 PMCID: PMC10092282 DOI: 10.1111/ejh.13884] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/08/2022] [Revised: 10/09/2022] [Accepted: 10/11/2022] [Indexed: 01/20/2023]
Abstract
OBJECTIVES To evaluate the role of additional chemotherapy before autologous hematopoietic cell transplantation (HCT) in patients with relapse/refractory diffuse large B-cell lymphoma (DLBCL) who achieve partial remission following first salvage therapy. METHODS We conducted a multicenter retrospective study of all adult patients with DLBCL who underwent HCT between 2008 and 2020 and achieved partial response (PR) after the first salvage and were either referred directly to HCT (n = 47) or received additional salvage therapy before HCT (n = 22). RESULTS Post-HCT CR rate and progression-free survival were comparable between the two groups (66% vs. 68%, p = .86 and median not reached vs. 10.2 months [95% confidence interval, CI 7.1-12.3], p = .27, respectively). Median overall survival (OS) and estimated 3-year OS favored patients who were directly referred to HCT (105.8 [95% CI 63-148] months vs. 14.5 [95% CI 0-44] months, p = .035, and 65% [95% CI 51%-75%] vs. 40% [95% CI 21%-53%], p = .035, respectively). In Cox regression model, while International Prognostic Index and primary refractory versus relapse disease did not impact OS, allocation to a second salvage regimen and older age were both associated with inferior survival (hazard ratio [HR] = 2.57 95% CI 1.1-5.8, p = .023 and HR = 1.04 95% CI 0.99-1.2, p = .064, respectively). CONCLUSIONS Referring patients with chemotherapy-sensitive disease in PR directly to HCT is associated with better OS compared to those receiving additional lines of treatment.

Cost saving, patient centered algorithm for progenitor cell mobilization for autologous hematopoietic cell transplantation. J Clin Apher 2021; 36:553-562.

Abstract
Administration of plerixafor with granulocyte-colony stimulating factor (G-CSF) mobilizes CD34+ cells much more effectively than G-CSF alone, but cost generally limits plerixafor use to patients at high risk of insufficient CD34+ cell collection based on low peripheral blood (PB) CD34+ counts following 4 days of G-CSF. We analyzed costs associated with administering plerixafor to patients with higher day 4 CD34+ cell counts to decrease apheresis days and explored the use of a fixed split dose of plerixafor instead of weight-based dosing. We analyzed 235 patients with plasma cell disorders or non-Hodgkin's lymphoma who underwent progenitor cell mobilization and autologous hematopoietic cell transplantation (AHCT) between March 2014 and December 2017. Two hundred ten (89%) received G-CSF plus Plerixafor and 25 (11%) received G-CSF alone. Overall, 180 patients (77%) collected in 1 day, 53 (22%) in 2 days and 2 (1%) in 3 days. Based on our data, we present a probabilistic algorithm to identify patients likely to require more than one day of collection using G-CSF alone. CD34+ cell yield, ANC and platelet recovery were not significantly different between fixed and standard dose plerixafor. Plerixafor enabled collection in 1 day and with estimated savings of $5000, compared to patients who did not receive plerixafor and required collection for three days. While collection and processing costs and patient populations vary among institutions, our results suggest re-evaluation of current algorithms.

Abstract
INTRODUCTION Lenalidomide maintenance, commonly prescribed in the postautologous transplantation (AHCT) setting for multiple myeloma (MM), is associated with development of secondary primary malignancies (SPM). Proteasome inhibitor maintenance (PIM) has also been evaluated in MM. We conduct a systematic review/meta-analysis to assess the efficacy of PIM in MM. METHODS Performing a comprehensive search of the medical literature using PubMed/Medline and EMBASE on September 11, 2019, we extracted data on clinical outcomes related to benefits (OS, PFS, and depth of hematologic response [DOHR]) and harms (SPM and adverse events). 2144 references were identified; three studies were eligible for inclusion. RESULTS A total of 1760 patients were included in the analysis; 507 patients received bortezomib and 395 received ixazomib maintenance. Control arms were either placebo (n = 261) or thalidomide (n = 358). PIM did not improve OS (HR 0.88, 95% CI 0.73-1.05, P = .15) but improved PFS (HR 0.77, 95% CI 0.69-0.86, P ≤ .00001) and DOHR (HR 0.88, 95% CI 0.79-0.98, P = .02) compared with control. There were no significant differences between PIM and control regarding SPM (p = NS) and ≥grade 3 peripheral neuropathy (PN) (p = NS). CONCLUSIONS PIM following AHCT in MM improves PFS and DOHR without an increase in development of SPM or severe PN compared with placebo/thalidomide.

Abstract
Hematopoietic cell transplantation (HCT) is an essential component of potentially curative therapy for patients with hematologic malignancies. High-dose chemotherapy with autologous (auto) stem cell rescue is used to overcome chemoresistance in multiple myeloma, non-Hodgkin lymphoma, and Hodgkin lymphoma. Alternatively, poor-risk acute leukemias rely on the graft versus leukemia effect of allogeneic (allo) products. Long-term remissions are feasible with both auto- and allo-HCT; however, disease relapse is the leading cause of death after HCT for many patients. In recognition of this, novel therapies are being investigated in the upfront, relapsed/refractory, and post-HCT maintenance settings to deepen response and maintain disease control. To date, the most robust data to support this approach are in multiple myeloma, where post-transplant maintenance therapy has improved clinical outcomes. In Hodgkin lymphoma, patients with high-risk features may benefit from post-auto-HCT vedotin (BV) regardless of pre-HCT BV exposure. Apart from mantle cell lymphoma, where rituximab maintenance is generally accepted, post-auto-HCT maintenance in other forms of NHL is less established. In patients who undergo allo-HCT, the utilization of maintenance therapy is an important component of improving post-HCT outcomes, however, an individualized approach that considers patient factors such as residual toxicity from HCT, an immature graft with poor graft function, infection, and graft-versus-host disease create a complex environment for aggressive interventions. Initiation of directed agents in patients with identified mutations prior to allo-HCT, including FLT3 in acute myeloid leukemia and Philadelphia chromosome in acute lymphoid leukemia have generally improved post-HCT outcomes. Ongoing studies are exploring the safety and efficacy of additional maintenance strategies post-allo-HCT in an effort to further improve post-HCT outcomes.

Abstract
Engraftment syndrome (ES), a complication of autologous hematopoietic cell transplantation (auto-HCT), can occur around the time of neutrophil recovery. We sought to identify the incidence of ES in light chain (AL) amyloidosis patients undergoing auto-HCT at our centre by evaluating 72 consecutive amyloidosis patients transplanted between 1999 and 2017. To assess trends in ES over time, patients were divided into two Eras (Era 1 = 1999-2008 and Era 2 = 2009-2017) based on year of auto-HCT. Twenty-two (31%) patients developed ES; three (16%) and 19 (36%) in Era 1 and 2, respectively (p = .1). Three (16%) and 51 (96%) patients in Era 1 and 2 received chemotherapy before auto-HCT (p = <.001). The most common symptoms observed with ES in addition to fever was diarrhoea (73%), rash (68%), weight gain (56%) and non-cardiogenic pulmonary oedema (23%). Day 100 post-auto-HCT haematological response (19.5% vs. 14%, p = .7) or post-transplant best organ response (23% vs. 36%, p = .2) were not significantly different in patients who did not or did develop ES, respectively. In this single centre series, we define the incidence and characteristics of ES in AL amyloidosis patients undergoing auto-HCT.

Abstract
Effective hematopoietic cell transplantation relies upon collecting adequate numbers of CD34+ hematopoietic stem cells, typically from peripheral blood. A minimum of ≥2 × 106 CD34+ cells/kg are necessary, while transplants of ≥5-6 × 106 CD34+ cells/kg are associated with improved hematopoietic recovery. Granulocyte colony stimulating factor (G-CSF) remains the gold standard for hematopoietic stem cell mobilization. However, in randomized trials for autologous-hematopoietic cell transplantation in multiple myeloma, approximately 45% of patients remain unable to optimally mobilize with G-CSF alone despite multiple injections and apheresis days. Therefore, reducing mobilization failures remains an unmet need. The study objective is to evaluate the superiority of one dose of BL-8040 plus G-CSF over placebo plus G-CSF to mobilize ≥6.0 × 106 CD34+ cells/kg in up to two apheresis days.

Abstract
BACKGROUND Obesity has implications for hematopoietic progenitor cell (HPC) mobilization, chemotherapy administration, and medication dosing. We analyzed the impact of obesity on HPC mobilization as well as key outcomes that are associated with cell dose in autologous hematopoietic cell transplantation (AHCT) recipients. METHODS We conducted a retrospective cohort study on 556 consecutive eligible AHCT recipients at our institution from 1/2004 to 12/2009. Patients were categorized into four groups based on the body mass index (BMI): underweight (BMI < 18.5), normal (18.5-24.9), overweight (25.0-29.9), or obese (≥30.0). Primary endpoints of interest included HPC mobilization, neutrophil and platelet recovery, hospital stay and survival. RESULTS The diagnoses were mostly non-Hodgkin lymphoma, multiple myeloma, and Hodgkin lymphoma. The majority of the patients had received three or less prior chemotherapy regimens and had not received prior radiation therapy. Most patients had chemosensitive disease at time of transplant. For HPC mobilization regimen, 68% received chemotherapy and G-CSF, 32% received G-CSF alone. Busuflan/etoposide/cyclophosphamide, melphalan, and busulfan/cyclophosphamide were used for conditioning. Obesity did not correlate with HPC mobilization and had no association with neutrophil or platelet recovery, or length of transplant hospitalization. On multivariable analysis, obese patients demonstrated better survival than those who were not obese. CONCLUSION Obese AHCT recipients had similar rates of HPC mobilization, neutrophil and platelet engraftment and length of transplant hospitalization, and experienced better survival compared with recipients with lower BMI. High BMI by itself should not be considered as a contraindication to AHCT.

Abstract
BACKGROUND The spectrum of infectious complications in autologous hematopoietic cell transplant recipients (AHCT) with multiple myeloma has not been well described in the recent era of novel agent induction and improved supportive care. METHODS We conducted a retrospective cohort study of 413 adult myeloma AHCT recipients at our institution from 2007-2016 to describe the cumulative incidence and risk factors for various infections and FN occurring within the first 100 days after AHCT. Additionally, landmark analysis was done among 404 patients who survived at least 100 days after transplant admission to estimate the association of infections with subsequent non-relapse mortality (NRM), overall survival (OS), and relapse-free survival (RFS). RESULTS Cumulative incidences (95% CI) of infection events by day 100 were: FN 43% (38-48), any infection 21% (17-25), bacterial 17% (14-21), viral 4% (3-7) and fungal 1% (0.5-3), central line-associated blood stream infection 3% (2-6), and Clostridium difficile colitis 6% (4-8). Patients with infection had a longer initial transplant hospitalization (median 17 vs 16 days, P < 0.01), more readmissions (31% vs 8%, P < 0.01), and spent more days in hospital in first 100 days (median 18 vs 16 days, P < 0.01). A 100-day mortality was low and similar between groups (2% vs 1%, P = 0.28). In landmark analysis of 404 100-day survivors, OS was worse among patients with early infections (hazard ratio 1.54 [1.03-2.30], P = 0.03), although there was no difference in NRM and RFS. CONCLUSIONS Notwithstanding advances in supportive care, early infectious complications remain a relevant source of morbidity and require attention in myeloma AHCT recipients.

Abstract
Lymphomas constitute the second most common indication for autologous hematopoietic cell transplantation (AHCT). Graft infusion is followed by a rapid hematological recovery and slower immune recovery. The number of natural killer cells and CD3+ T lymphocytes achieve normal counts usually within a month, whereas the recovery of CD3+CD4+ T lymphocytes is much slower. Early immune recovery is usually defined as the absolute lymphocyte count (ALC) ≥0.5 × 109/L, which has been associated with improved progression-free and even overall survival. Several factors have been associated with early immune recovery, including higher infused lymphocyte and CD34+ cell doses, both of which are affected by the choice of mobilization. This review summarizes the clinical importance of early immune recovery for long-term success of AHCT in lymphomas. Factors known to affect early immune recovery are discussed and suggestions made how to improve mobilization and collection processes to optimize immune recovery and post-transplant outcomes.

Abstract
Standard therapy for acute myeloid leukemia (AML) consists of hematopoietic cell transplantation (HCT) including autologous-HCT (AUTO) and allogeneic-HCT from a matched-sibling donor (MSD) or well-matched unrelated donor (WM-URD). When a conventional donor is not available, HCT from a partially-matched (PM)-URD or familial-mismatched donor (FMMD) is typically considered. We analyzed 561 patients with intermediate to poor-risk molecular cytogenetics who underwent transplant from 2002 to 2013 in their first remission. Engraftment was successful in all donor types except five patients who died in aplasia. Disease-free survival (DFS) at 5 years was 61.4% for MSD, 62.1% for WM-URD, 65.3% for FMMD, 44.7% for AUTO and 36.8% for PM-URD. AUTO showed the highest relapse rate (51.0%) compared to MSD (23.5%) and FMMD (18.5%), but showed the lowest 5-year non-relapse mortality (NRM) rate (3.8%). PM-URD showed the highest NRM (29.3%) with more instances of acute graft-vs.-host disease (GVHD) with grade≥III (29.3%), compared to MSD (15.6%) and FMMD (15.7%). In a poor-risk subgroup, the 5-year DFS for FMMD and MSD was 59.8% and 46.7%, respectively, while for AUTO and PM-URD it was 12.6% and 0.0%, respectively, which was caused by a high relapse rate (87.1% in AUTO, 83.3% in PM-URD). In the intermediate-risk subgroup, the 5-year DFS of AUTO (53.9% was not different from the conventional donors in multivariate analysis, presenting a low NRM rate (5.1%). FMMD should be considered prior to PM-URD in intermediate-to-poor-risk AML and GVHD prophylaxis should be intensified when PM-URD is needed. AUTO might be considered for selected patients in the intermediate-risk group.

Neutropenic fever during peripheral blood progenitor cell mobilization is associated with decreased CD34+ cell collection and increased apheresis collection days. J Clin Apher 2017; 33:303-309. [PMID: 29134688 DOI: 10.1002/jca.21605] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/04/2017] [Revised: 08/29/2017] [Accepted: 11/03/2017] [Indexed: 12/28/2022]
Abstract
BACKGROUND Peripheral blood progenitor cell (PBPC) mobilization with chemotherapy in addition to Granulocyte-Colony Stimulating Factor (G-CSF) improves cell collection compared to G-CSF alone; however, it is associated with increased risk of neutropenic fever (NF). METHODS We analyzed risk factors for post-priming NF and NF association with autologous stem cell transplant outcomes. Between 1998 and 2008, 593 adult patients with lymphoma underwent PBPC mobilization with etoposide and G-CSF. RESULTS Median age was 51 years (range 18-77) and 372 (63%) were male. Diagnoses were 457 (77%) non-Hodgkin lymphoma and 136 (23%) Hodgkin lymphoma. Of 554 (93%) transplanted patients, majority were in complete or partial remission at time of transplant (88%). Overall, 141 (24%) patients were hospitalized for NF. Nine patients (6%) had bacteremia, 4 (3%) had pneumonia, 2 (<1%) had herpes simplex viral infections, and the remaining 126 (90%) had no identified infection source. NF patients had lower likelihood of proceeding to transplant (86% vs. 96%, P < .001), lower CD34+ cell dose collection (median 7.23 × 106 CD34+ cells/kg vs. 8.98 × 106 CD34+ cells/kg, P = .002), and were more likely to require > 4 days of apheresis (48% vs. 37%, P < .001). NF was associated with a higher 30-day readmission rate following transplant hospitalization (17% vs. 9%, P = .012). CONCLUSION NF during etoposide priming is associated with lower likelihood of proceeding to transplant, lower CD34+ cell dose collection, more apheresis days required for collection and a higher 30-day readmission rate following transplant discharge.

Abstract
Breast implant-associated anaplastic large-cell lymphoma will be identified as a separate nosological entity in the 2017 adapted WHO classification due to differences in its clinical presentations, pathogenesis, and prognosis with those of nodal and cutaneous anaplastic large-cell lymphomas. The paper gives a review of the literature and describes the authors' own clinical case of common breast implant-associated anaplastic large-cell lymphoma involving breast tissue, axillary lymph nodes, anterior chest muscles, and bone marrow. The treatment policy chosen by the authors could achieve complete remission.

Targeting complete response with upfront bortezomib consolidation versus observation after the achievement of complete response following autologous transplantation for multiple myeloma (TUBA study). Hematol Oncol 2017; 36:202-209.

Abstract
Complete response (CR) after treatment for multiple myeloma is associated with superior progression-free survival (PFS). Multiple myeloma patients were prospectively recruited for induction treatment with bortezomib and dexamethasone (BD) followed by autologous hematopoietic cell transplantation (auto-HCT) between 2010 and 2012. If patients did not achieve CR after auto-HCT, BD consolidation therapy was added to target CR. After the BD induction phase (n = 46), greater than or equal to CR was achieved in 4 patients (8%). After auto-HCT (n = 34), greater than or equal to CR was achieved in 9 patients (20%) and very good partial response (VGPR) was achieved in 11 (24%). Of the 24 patients who received auto-HCT and whose response was less than CR, 21 received BD consolidation therapy for a median of 4 courses. Finally, the maximum response with or without BD consolidation was greater than or equal to CR in 19 (41%), VGPR in 7 (15%), and PR in 6 (13%). Through BD consolidation, CR was achieved in 8 of 11 patients with post-HCT VGPR and in 2 of 12 patients with post-HCT PR. In total, 4 year PFS and overall survival were 43 and 80%, respectively. After adjusting for clinical factors, there was no difference in PFS between CR patients after auto-HCT and BD consolidation, while patients with less than or equal to VGPR after consolidation had a significantly lower PFS. Patients with post-HCT CR showed good PFS, and targeting CR through BD consolidation could improve the CR rate. It would be worthwhile to prospectively compare the efficacy of consolidation only for patients who failed to achieve CR to a universal consolidation strategy.

Abstract
We conducted a retrospective registry-based study involving 198 patients with acute promyelocytic leukemia (APL) who underwent autologous hematopoietic cell transplantation (HCT) during second complete remission (CR2) from 1995 to 2012. Arsenic trioxide (ATO) became commercially available in Japan in December 2004, and a substantial increase in the annual numbers of transplantations has occurred since 2005. Patients transplanted after 2006 had significantly better relapse-free and overall survival than those transplanted before 2004 (p = .028 and p = .027, respectively). There was a significant difference in cumulative incidence of relapse in favor of those transplanted after 2006 (p = .008), whereas non-relapse mortality did not differ between the two groups (p = .683). Our findings suggest that the introduction of ATO may have reduced post-transplantation relapse without increasing non-relapse mortality, resulting in significant improvements in overall outcomes for relapsed APL patients undergoing autologous HCT during CR2.

Abstract
PB is a source of HSC, especially for autologous HCT in solid tumors. However, there is a risk of failing to achieve the target number of SC after mobilization with growth factors alone in patients who were heavily pretreated with chemotherapy or those in need for tandem transplants. SC were harvested from seven pediatric patients with solid tumors who were in need of autologous HCT following combination GCSF and plerixafor. Six of them received plerixafor after failing to achieve enough SC with GCSF only, while the seventh patient received the combined protocol upfront. All seven patients achieved the target number of SC according to their treatment protocol. There were no adverse events. All patients underwent autologous HCT using the harvested HSC and achieved full engraftment. A protocol for harvesting autologous HCT using GCSF and plerixafor is feasible and safe in children with solid tumors who had been heavily pretreated with chemotherapy or needed tandem transplants.

Abstract
BACKGROUND Patients undergoing hematopoietic cell transplantation (HCT) for hematological malignancies experience a number of challenges during treatment. There is growing evidence that malglycemia (hyperglycemia, hypoglycemia, and/or increased glycemic variability) contributes to HCT-related complications, even in patients without preexisting diabetes. The purpose of this pilot study was to investigate factors influencing glycemic status and associated infection occurrences in nondiabetic autologous HCT recipients. METHODS Oncology patients without preexisting diabetes treated with autologous HCT at a National Cancer Institute-designated cancer center were followed from admission through discharge or 28 days post-HCT. Patients had morning fasting laboratory tests. Descriptive statistics and Cox proportional hazards models were used to examine associations between BG levels and risk for infection while adjusting for baseline covariates including age, body mass index (BMI), cumulative glucocorticoid dose, and diagnosis. RESULTS The sample included 28 female and 25 male predominately non-Hispanic White patients (mean age 55.7 years, SD = 11.32). Blood glucose (BG) range was 35-325 mg/dl. Twenty-three patients incurred at least one infection. BMI ≥ 25 kg/m(2) was associated with high BG and infections. In the multivariate Cox model, an increase of 1 interquartile range in BG 2 days before infection was associated with a moderately increased risk of infection (hazard ratio = 1.44, p = .008). CONCLUSIONS Understanding the contributors to and consequences of malglycemic events can lead to better protocols for identifying patients at greater risk for infection. Further investigation is warranted for interventions to mitigate BG events for improved outcomes.

Abstract
Lymphomas with recurrent chromosomal breakpoints activating multiple oncogenes, including MYC, BCL2, and BCL6 are often referred to as "Dual Hit" or "Double Hit" lymphomas (DHL). In the updated classification for malignant lymphomas by the World Health Organization (WHO), the novel category of "B-cell lymphoma unclassifiable with features intermediate between diffuse large B-cell lymphoma (DLBCL) and Burkitt's lymphoma (BL)" was proposed in an attempt to create a (temporary) container for aggressive mature B-cell lymphomas that should not be diagnosed as either BL or DLBCL. DHL make up an important part of this novel WHO category, the other part representing heterogeneous cases of aggressive B-cell lymphoma that have features of BL. DHL are highly aggressive lymphomas with generally poor response to first line and salvage treatment. Limited data is available to guide therapeutic decisions, and despite aggressive measures including high dose (HD) chemotherapy followed by autologous hematopoietic cell transplantation (AHCT), outcome is unsatisfyingly poor. Herein, we report a case of a patient with DHL and review the relevant literature.
