Abstract: Compared with the general population, hematopoietic cell transplantation (HCT) survivors are at elevated risk for developing solid subsequent neoplasms (SNs). The Center for International Blood and Marrow Transplant Research (CIBMTR) is a key resource for quantifying solid SN incidence following HCT, but the completeness of SN ascertainment is uncertain. Within a cohort of 18 450 CIBMTR patients linked to the California Cancer Registry (CCR), we evaluated the completeness of solid SN data reported to the CIBMTR from 1991 to 2018 to understand the implications of using CIBMTR data alone or combined with CCR data to quantify the burden of solid SNs after HCT. We estimated the cumulative incidence of developing a solid SN, accounting for the competing risk of death. Within the cohort, solid SNs were reported among 724 patients; 15.6% of these patients had an SN reported by CIBMTR only, 36.9% by CCR only, and 47.5% by both. The corresponding cumulative incidence of developing a solid SN at 10 years following a first HCT was 4.0% (95% confidence interval [CI], 3.5-4.4) according to CIBMTR data only, 5.3% (95% CI, 4.9-5.9) according to CCR data only, and 6.3% (95% CI, 5.7-6.8) according to both sources combined. The patterns were similar for allogeneic and autologous HCT recipients. Linking detailed HCT information from CIBMTR with comprehensive SN data from cancer registries provides an opportunity to optimize SN ascertainment for informing follow-up care practices and evaluating risk factors in the growing population of HCT survivors., (Licensed under Creative Commons Attribution-NonCommercial-NoDerivatives 4.0 International (CC BY-NC-ND 4.0), permitting only noncommercial, nonderivative use with attribution.)

Low socioeconomic status (SES) is a risk factor for mortality and immune dysfunction across a wide range of diseases, including cancer. However, cancer is distinct in the use of allogeneic hematopoietic cell transplantation (HCT) as a treatment for hematologic malignancies to transfer healthy hematopoietic cells from one person to another. This raises the question of whether social disadvantage of an HCT cell donor, as assessed by low SES, might impact the subsequent health outcomes of the HCT recipient. To evaluate the cellular transplantability of SES-associated health risk, we analyzed the health outcomes of 2,005 HCT recipients who were transplanted for hematologic malignancy at 125 United States transplant centers and tested whether their outcomes differed as a function of their cell donor's SES (controlling for other known HCT-related risk factors). Recipients transplanted with cells from donors in the lowest quartile of SES experienced a 9.7% reduction in overall survival ( P = 0.001) and 6.6% increase in treatment-related mortality within 3 y ( P = 0.008) compared to those transplanted from donors in the highest SES quartile. These results are consistent with previous research linking socioeconomic disadvantage to altered immune cell function and hematopoiesis, and they reveal an unanticipated persistence of those effects after cells are transferred into a new host environment. These SES-related disparities in health outcomes underscore the need to map the biological mechanisms involved in the social determinants of health and develop interventions to block those effects and enhance the health of both HCT donors and recipients., Competing Interests: Competing interests statement:The authors declare no competing interest.

Assessing outcomes following hematopoietic cell transplantation (HCT) poses challenges due to the necessity for systematic and often prolonged patient follow-up. Linking the HCT database of the Center for International Blood and Marrow Transplant Research (CIBMTR) with cancer registry data may improve long-term outcome ascertainment, but the reliability of mortality data in death certificates from cancer registries among HCT recipients remains unknown. We compared the classification of vital status and primary cause of death (COD), as well as the length of follow-up between the CIBMTR and California Cancer Registry (CCR) to assess the possibility of supplementing the CIBMTR with cancer registry data. This retrospective study leveraged a linked CIBMTR-CCR dataset. We included patients who were California residents at the time of HCT and received a first allogeneic (allo) or autologous (auto) HCT for a hematologic malignancy diagnosed during 1991-2016. Follow-up was through 2018. We analyzed 18,450 patients (alloHCT, n = 8232; autoHCT, n = 10,218). The Vital status agreement was 97.7% for alloHCT and 97.2% for autoHCT. Unknown COD was higher in CIBMTR (12.9%) than in CCR (1.6%). After excluding patients with unknown COD information, the overall agreement of primary COD (cancer versus noncancer) was 53.7% for alloHCT and 83.2% for autoHCT. This agreement was lower within the first 100 days post-HCT (alloHCT, 31.0%; autoHCT, 54.6%). Compared with CIBMTR, deaths due to cancer were higher in CCR (alloHCT, 90.0%; autoHCT, 90.1% versus alloHCT, 47.3%; autoHCT, 82.5% in CIBMTR). CIBMTR reports more frequently noncancer-related deaths, including graft-versus-host disease and infections. The cumulative incidence of cancer-specific mortality at 20 years differed, particularly for alloHCT (CCR, 53.7%; CIBMTR, 27.6%). The median follow-up among alive patients was longer in CCR (alloHCT, 6.0 years; autoHCT, 4.7 years) than in CIBMTR (alloHCT, 5.0 years; autoHCT, 3.8 years). Our findings highlight the completeness of vital status data in CIBMTR but reveal substantial disagreement in primary COD. Consequently, caution is required when interpreting HCT studies that use only death certificates to estimate cause-specific mortality outcomes. Improving the accuracy of COD registration and follow-up completeness by developing communication pathways between cancer registries and hospital-based cohorts may enhance our understanding of late effects and long-term outcomes among HCT survivors., (Copyright © 2023.

The use of HLA-mismatched donors could enable more patients with ethnically diverse backgrounds to receive allogeneic hematopoietic cell transplantation (HCT) in the United States. However, real-world trends and outcomes following mismatched donor HCT for diverse patients remain largely undefined. We conducted this study to determine whether the use of mismatched donor platforms have increased the access to allogeneic HCT for ethnically diverse patients, particularly through the application of novel graft-versus-host disease (GVHD) prophylaxis regimens, and whether outcomes for diverse patients are comparable to those of non-Hispanic White patients. This observational cross-sectional study used real-world data from the Center for International Blood and Marrow Transplant Research (CIBMTR) registry. All patients receiving their first allogeneic HCT in the United States between 2009 and 2020 were included, with a focus on transplantations performed in 2020. Data from patients undergoing allogeneic HCT using bone marrow, peripheral blood, or cord blood from HLA-matched or mismatched related and unrelated donors were analyzed. Specifically, relative proportion of allogeneic HCT was generated as percentage of total for donor type and for patient age, disease indication, GVHD prophylaxis, and race and ethnicity. Causes of death were summarized using frequencies, and the Kaplan-Meier estimator was used for estimating overall survival. Compared to matched related donor and matched unrelated donor HCT, more ethnically diverse patients received mismatched unrelated donor, haploidentical donor, and cord blood HCT. Although matched unrelated donor remains the most common donor type, the use of haploidentical donors has increased significantly over the last 5 years. Paralleling this increase in haploidentical HCT is the increased use of post-transplantation cyclophosphamide (PTCy) as GVHD prophylaxis. Relative to previous transplantation eras, the most contemporary era is associated with the highest survival rates following allogeneic HCT irrespective of patient race and ethnicity. Nonetheless, disease relapse remains the primary cause of death for both adult and pediatric allogeneic HCT recipients by donor type and across all patient racial/ethnic groups. Ethnically diverse patients are undergoing allogeneic HCT at higher rates, largely through the use of alternative donor platforms incorporating PTCy. Maintaining access to potential life-saving allogeneic HCT using alternative donors and novel GVHD prophylaxis strategies and improving HCT outcomes, particularly disease relapse, remain urgent clinical needs., (Copyright © 2023 The American Society for Transplantation and Cellular Therapy.

From 2016 EBMT and JACIE developed an international risk-adapted benchmarking program of haematopoietic stem cell transplant (HSCT) outcome to provide individual EBMT Centers with a means of quality-assuring the HSCT process and meeting FACT-JACIE accreditation requirements relating to 1-year survival outcomes. Informed by previous experience from Europe, North America and Australasia, the Clinical Outcomes Group (COG) established criteria for patient and Center selection, and a set of key clinical variables within a dedicated statistical model adapted to the capabilities of the EBMT Registry. The first phase of the project was launched in 2019 to test the acceptability of the benchmarking model through assessment of Centers' performance for 1-year data completeness and survival outcomes of autologous and allogeneic HSCT covering 2013-2016. A second phase was delivered in July 2021 covering 2015-2019 and including survival outcomes. Reports of individual Center performance were shared directly with local principal investigators and their responses were assimilated. The experience thus far has supported the feasibility, acceptability and reliability of the system as well as identifying its limitations. We provide a summary of experience and learning so far in this 'work in progress', as well as highlighting future challenges of delivering a modern, robust, data-complete, risk-adapted benchmarking program across new EBMT Registry systems., (© 2023.

COVID-19 has significantly impacted the practice of hematopoietic cell transplantation (HCT) and likely affected outcomes of HCT recipients. Early reports document substantially higher case fatality rates for HCT recipients than seen in faced by the general population. Currently we do not have a clear picture of how much of this threat is present within the first year after HCT and how infection rates and outcomes vary with time after HCT. There are important because center-specific survival estimates for reporting purposes focus on 1-year post-HCT mortality. Transplantation centers have dramatically changed their practices in response to the pandemic. At many centers, quality assurance processes and procedures were disrupted, changes that likely affected team performance. Centers have been affected unevenly by the pandemic through time, location, and COVID-19 burdens. Assessment of center-specific survival depends on the ability to adjust for risk factors, such as COVID-19, that are outside center control using consistent methods so that team performance based on controllable risk factors can be ascertained. The Center for International Blood and Marrow Transplantation Research (CIBMTR) convened a working group for the 2020 Center Outcomes Forum to assess the impact of COVID-19 on both patient-specific risks and center-specific performance. This committee reviewed the factors at play and developed recommendations for a process to determine whether adjustments in the methodology to assess center-specific performance are needed., (Copyright © 2021 The American Society for Transplantation and Cellular Therapy.

Background: The association of community factors and outcomes after hematopoietic cell transplantation (HCT) has not been comprehensively described. Using the County Health Rankings and Roadmaps (CHRR) and the Center for International Blood and Marrow Transplant Research (CIBMTR), this study evaluated the impact of community health status on allogeneic HCT outcomes., Methods: This study included 18,544 adult allogeneic HCT recipients reported to the CIBMTR by 170 US centers in 2014-2016. Sociodemographic, environmental, and community indicators were derived from the CHRR, an aggregate community risk score was created, and scores were assigned to each patient (patient community risk score [PCS]) and transplant center (center community risk score [CCS]). Higher scores indicated less healthy communities. The impact of PCS and CCS on patient outcomes after allogeneic HCT was studied., Results: The median age was 55 years (range, 18-83 years). The median PCS was -0.21 (range, -1.37 to 2.10; standard deviation [SD], 0.42), and the median CCS was -0.13 (range, -1.04 to 0.96; SD, 0.40). In multivariable analyses, a higher PCS was associated with inferior survival (hazard ratio [HR] per 1 SD increase, 1.04; 99% CI, 1.00-1.08; P = .0089). Among hematologic malignancies, a tendency toward inferior survival was observed with a higher PCS (HR, 1.04; 99% CI, 1.00-1.08; P = .0102); a higher PCS was associated with higher nonrelapse mortality (NRM; HR, 1.08; 99% CI, 1.02-1.15; P = .0004). CCS was not significantly associated with survival, relapse, or NRM., Conclusions: Patients residing in counties with a worse community health status have inferior survival as a result of an increased risk of NRM after allogeneic HCT. There was no association between the community health status of the transplant center location and allogeneic HCT outcomes., (© 2020 American Cancer Society.)

Hematopoietic cell transplantation (HCT) is a well-established treatment to control and/or cure many malignant and nonmalignant diseases involving the hematopoietic system and some solid tumors. We report information about HCT procedures performed in the United States in 2018 and analyze trends and outcomes of HCT as reported to the Center for International Blood and Marrow Transplant Research (CIBMTR). Overall, compared with 2017, the number of allogeneic HCTs performed in the United States increased by 1%, and the number of autologous HCTs decreased by 5%. Key findings are fewer autologous HCTs performed for non-Hodgkin lymphoma and increasing numbers of haploidentical HCTs, nearly all of which use post-transplantation cyclophosphamide for graft-versus-host disease prophylaxis. There is a continuing increase in HCT in adults age >70 years, particularly for acute myelogenous leukemia and myelodysplastic syndromes. Survival rates by disease, disease stage, donor type, and age are presented. This report, prepared annually by the CIBMTR, provides a snapshot of current transplant activity in the United States., (Copyright © 2020 American Society for Transplantation and Cellular Therapy.

In many healthcare settings, benchmarking for complex procedures has become a mandatory requirement by competent authorities, regulators, payers and patients to assure clinical performance, cost-effectiveness and safe care of patients. In several countries inside and outside Europe, benchmarking systems have been established for haematopoietic stem cell transplantation (HSCT), but access is not universal. As benchmarking is now integrated into the FACT-JACIE standards, the EBMT and JACIE established a Clinical Outcomes Group (COG) to develop and introduce a universal system accessible across EBMT members. Established systems from seven European countries (United Kingdom, Italy, Belgium, France, Germany, Spain, Switzerland), USA and Australia were appraised, revealing similarities in process, but wide variations in selection criteria and statistical methods. In tandem, the COG developed the first phase of a bespoke risk-adapted international benchmarking model for one-year survival following allogeneic and autologous HSCT based on current capabilities within the EBMT registry core dataset. Data completeness, which has a critical impact on validity of centre comparisons, is also assessed. Ongoing development will include further scientific validation of the model, incorporation of further variables (when appropriate) alongside implementation of systems for clinically meaningful interpretation and governance aiming to maximise acceptance to centres, clinicians, payers and patients across EBMT.

Importance: In 2010, the US Centers for Medicare & Medicaid Services (CMS) indicated that data regarding efficacy of allogeneic hematopoietic stem cell transplantation (HCT) in the CMS beneficiary population with myelodysplastic syndrome (MDS) were currently insufficient, but that coverage would be provided for patients enrolled in a clinical study that met its criteria for Coverage with Evidence Development (CED)., Objective: The Center for International Bone Marrow Transplant Research (CIBMTR) submitted a study concept comparing the outcomes of patients aged 55 to 64 years vs aged 65 years or older who met those criteria, effectively providing coverage by CMS for HCT for MDS., Design, Setting, and Participants: Data on patients aged 65 years or older were prospectively collected and their outcomes compared with patients aged 55 to 64 years. Patients were enrolled in the study from December 15, 2010, to May 14, 2014. The results reported herein were analyzed as of September 4, 2017, with a median follow-up of 47 months. The study was conducted by the CIBMTR. It comprises a voluntary working group of more than 420 centers worldwide that contribute detailed data on allogeneic and autologous HCT and cellular therapies., Interventions: Patients with MDS received HCT according to institutional guidelines and preferences., Main Outcomes and Measures: The primary outcome was overall survival (OS); secondary outcomes included nonrelapse mortality (NRM), relapse-free survival, and acute and chronic graft vs host disease., Results: During the study period, 688 patients aged 65 years or older underwent HCT for MDS and were compared with 592 patients aged 55 to 64 years. Other than age, there were no differences in patient and disease characteristics between the groups. On univariate analysis, the 3-year NRM rate was 28% vs 25% for the 65 years or older group vs those aged 55 to 64 years, respectively. The 3-year OS was 37% vs 42% for the 65 years or older group vs the 55 to 64 years age group, respectively. On multivariable analysis after adjusting for excess risk of mortality in the older group, age group had no significant association with OS (HR, 1.09; 95% CI, 0.94-1.27; P = .23) or NRM (HR, 1.19; 95% CI, 0.93-1.52; P = .16)., Conclusions and Relevance: Older patients with MDS undergoing HCT have similar OS compared with younger patients. Based on current data, we would recommend coverage of HCT for MDS by the CMS., Trial Registration: ClinicalTrials.gov identifier: NCT01166009.

Preclinical research shows that stress-induced activation of the sympathetic nervous system can promote hematopoietic malignancies via β-adrenoreceptor-mediated molecular pathways. Hematopoietic cell transplant (HCT) recipients exposed to conditions of chronic stress show activation of a conserved transcriptional response to adversity (CTRA) gene expression profile, which in turn is associated with increased relapse and decreased disease-free survival. We conducted a randomized controlled phase 2 biomarker trial testing the impact of the nonselective β-antagonist propranolol on CTRA-related gene expression of 25 individuals receiving an autologous HCT for multiple myeloma. Propranolol was administered for 1 week prior to and 4 weeks following HCT. Blood was collected at baseline, day -2, and day +28. Intention-to-treat analyses controlling for demographic characteristics, high-risk disease (International Myeloma Working Group risk score), and tumor stage tested effects on a 53-gene CTRA indicator profile and measures of CTRA-related cellular processes in peripheral blood mononuclear cells. Twelve participants were randomized to the intervention and 13 to the control. Relative to the control group, propranolol-treated patients showed greater decreases from baseline to HCT day -2 and day +28 for both CTRA gene expression (P = .017) and bioinformatic measures of CD16- classical monocyte activation (P = .005). Propranolol-treated patients also showed relative upregulation of CD34+ cell-associated gene transcripts (P = .011) and relative downregulation of myeloid progenitor-containing CD33+ cell-associated gene transcripts (P = .001). Ancillary analyses identified nonsignificant trends toward accelerated engraftment and reduced posttransplant infections in propranolol-treated patients. Peri-HCT propranolol inhibits cellular and molecular pathways associated with adverse outcomes. Changes in these pathways make propranolol a potential candidate for adjunctive therapy in cancer-related HCT., (© 2020 by The American Society of Hematology.)

Allogeneic hematopoietic cell transplantation (allo-HCT) with reduced-intensity conditioning (RIC) is commonly performed as an inpatient procedure. The feasibility and outcomes of RIC allo-HCT in the outpatient setting is not known. We performed a single-center retrospective cohort study of patients aged ≥ 18years with hematologic malignancies who underwent RIC allo-HCT either in the inpatient or outpatient setting. Donor types included HLA-matched sibling and well-matched unrelated donors. The objectives were to compare the survival, complications, charges, and incidences of relapse, nonrelapse mortality (NRM), and acute and chronic graft-versus-host disease (GVHD) between the 2 groups. Between 2014 and 2017, 151 eligible patients were included, with 116 undergoing RIC allo-HCT in the inpatient setting and 35 patients undergoing RIC allo-HCT in the outpatient setting. Baseline characteristics were comparable between the 2 groups except for a higher proportion of patients with myeloma in the outpatient cohort (inpatient 15.5% versus outpatient 37.1%). The cumulative incidence of grades II to IV acute GVHD (inpatient 25.2% versus outpatient 25.7%), grades III to IV acute GVHD (inpatient 10.4% versus outpatient 8.5%), chronic GVHD (inpatient 38.3% versus outpatient 51.6%), NRM at 1 year (inpatient 10.8% versus outpatient 3.2%), and relapse (inpatient 24.8% versus outpatient 33.2%) did not significantly differ between the 2 cohorts. One-year progression-free survival (inpatient 64.4% versus outpatient 63.6%, P = .39) and overall survival (inpatient 73.8% versus outpatient 82.8%, P = .93) were also not significantly different between the 2 groups. The proportion of patients who developed neutropenic fever (inpatient 25.8% versus outpatient 8.5%, P = .03) and mucositis (inpatient 50.8% versus outpatient 8.5%, P < .001) and who required total parenteral nutrition (inpatient 20.6% versus outpatient 5.7%, P = .04) were more frequent in the inpatient cohort. About 51.5% of the outpatient cohort never required hospital admission in the first 100days. Outpatient HCT resulted in significantly lower charges than inpatient HCT in the first 100days (median charges: inpatient $339,621 versus outpatient $247,334; P < .001). On multivariate analysis the site of the HCT (outpatient versus inpatient) was not a significant predictor of either overall or progression-free survival. Outpatient RIC allo-HCT is feasible and safe with daily outpatient evaluation and aggressive supportive care resulting in outcomes comparable with those who received the transplant in the inpatient setting., (Copyright © 2019 Elsevier Ltd.

To study the factors associated with poorer health-related quality of life at 1-year post-allogeneic hematopoietic cell transplantation (alloHCT), a secondary analysis of a prospective feasibility study was performed. Pediatric Quality of Life Inventory questionnaires were collected in 76 children undergoing alloHCT at baseline (within 30 d before transplantation), day 100, 6 months, and 12 months posttransplantation. The global score improved post-HCT (baseline: 67.1, 12 mo: 76.6). Females (odds ratio, 6.5; 95% confidence interval, 1.002-42.17; P=0.04) and patients with low baseline scores (odds ratio, 7.2; 95% confidence interval, 1.07-48.63; P=0.04) had lower scores at 12 months post-HCT and suggest a target group for early interventions such as physical exercise, stress management, and cognitive behavior therapy.

This study aimed to develop a survivorship care plan (SCP) that can be individualized to facilitate long-term follow-up care of hematopoietic cell transplantation (HCT) survivors. A sample SCP was developed that included 2 documents: a treatment summary and preventive care recommendations that combined data on treatment exposures routinely submitted by HCT centers to the Center for International Blood and Marrow Transplant Research (CIBMTR) with long-term follow-up guidelines. Focus groups were conducted by phone to characterize the critical patient-centered elements of the SCP. Focus group eligibility criteria included (1) adult patients >1 year post-HCT and their caregivers (3 groups; n = 22), (2) HCT physicians and advanced practice providers (APPs) (2 groups; n = 14), (3) HCT nurses and social workers (4 groups; n = 17), and (4) community health care professionals (3 groups; n = 24). Transcripts were analyzed for saturation of key themes using NVivo 10 software. Patients and caregivers suggested combining the treatment summary and care guidelines into a single document. They also requested sections on sexual and emotional health and the immune system. Providers wanted the treatment summary to focus only on what they absolutely must know. Themes were similar across healthcare professionals, although screening for psychosocial issues was emphasized more by the nurses and social workers. All preferred to receive the SCP electronically; however, hardcopy was considered necessary for some patients. All felt that the SCP would facilitate appropriate post-HCT care. This study highlights the need for an SCP instrument to facilitate HCT survivorship care. Furthermore, it demonstrates the feasibility and value of engaging HCT recipients, caregivers, and providers in developing an SCP. Their feedback was incorporated into a final SCP that was subsequently tested in a randomized trial., (Copyright © 2018 American Society for Blood and Marrow Transplantation.

Background: Exposures to DNA-damaging drugs and ionizing radiations increase risks of acute myeloid leukemia (AML) and myelodysplastic syndrome (MDS)., Methods: 9028 recipients of hematopoietic cell autotransplants (1995-2010) for Hodgkin lymphoma (HL; n = 916), non-Hodgkin lymphoma (NHL; n = 3546) and plasma cell myeloma (PCM; n = 4566), reported to the CIBMTR, were analyzed for risk of subsequent AML or MDS., Results: 335 MDS/AML cases were diagnosed posttransplant (3.7%). Variables associated with an increased risk for AML or MDS in multivariate analyses were: (1) conditioning with total body radiation versus chemotherapy alone for HL (HR = 4.0; 95% confidence interval [1.4, 11.6]) and NHL (HR = 2.5 [1.1, 2.5]); (2) ≥3 versus 1 line of chemotherapy for NHL (HR = 1.9 [1.3, 2.8]); and (3) subjects with NHL transplanted in 2005-2010 versus 1995-1999 (HR = 2.1 [1.5, 3.1]). Using Surveillance, Epidemiology and End Results (SEER) data, we found risks for AML/MDS in HL, NHL and PCM to be 5-10 times the background rate. In contrast, relative risks were 10-50 for AML and approximately 100 for MDS in the autotransplant cohort., Conclusions: There are substantial risks of AML and MDS after autotransplants for HL, NHL and PCM., (Copyright © 2018. Published by Elsevier Ltd.)

Significant advances in hematopoietic cell transplantation (HCT) have increased the long-term survivorship of its recipients, but because of unique complications arising from radiation and chemotherapy, recipients require lifelong follow-up. To evaluate current survivorship or long-term follow-up (LTFU) clinics specifically for HCT survivors and to evaluate the potential barriers in their establishment, the American Society for Blood and Marrow Transplantation (ASBMT) Practice Guidelines Committee electronically surveyed 200 HCT programs to gather quantitative and qualitative data about models of care. Among 77 programs (38.5%) that responded, 45% indicated presence of an LTFU clinic; however, LTFU care models varied with respect to services provided, specialist availability, type of patients served, and staffing. Among 55% of programs without an LTFU clinic, 100% agreed that allogeneic HCT survivors have unique needs separate from graft-versus-host disease and that complications could arise during the transition of care either from pediatric to adult settings or away from the HCT center. Lack of expertise, logistics, financial issues, and the observation that 84% of individual practitioners prefer to provide survivorship care were the identified obstacles to establishing new LTFU clinics. The ASBMT hopes that policymakers, HCT providers, and institutions will benefit from the results of this survey and recommends that delivering guidelines-driven screening and expert management of late effects is the goal of first-rate HCT survivorship care., (Copyright © 2018 The American Society for Blood and Marrow Transplantation.

Background: Repurposing existing medications for antineoplastic purposes can provide a safe, cost-effective, and efficacious means to further augment available cancer care. Clinical and preclinical studies suggest a role for the ß-adrenergic antagonist (ß-blocker) propranolol in reducing rates of tumor progression in both solid and hematologic malignancies. In patients undergoing hematopoietic cell transplantation (HCT), the peri-transplant period is a time of increased activity of the ß-adrenergically-mediated stress response., Methods: We conducted a proof-of-concept randomized controlled pilot study assessing the feasibility of propranolol administration to patients between ages 18-75 who received an autologous HCT for multiple myeloma. Feasibility was assessed by enrollment rate, tolerability, adherence, and retention., Results: One hundred fifty-four patients underwent screening; 31 (20%) enrolled in other oncology trials that precluded dual trial enrollment and 9 (6%) declined to enroll in the current trial. Eighty-nine (58%) did not meet eligibility requirements and 25 (16%) were eligible; of the remaining eligible patients, all were successfully enrolled and randomized. The most common reasons for ineligibility were current ß-blocker use, age, logistics, and medical contraindications. 92% of treatment arm patients tolerated and remained on propranolol for the study duration; 1 patient discontinued due to hypotension. Adherence rate in assessable patients (n = 10) was 94%. Study retention was 100%., Conclusions: Findings show that it is feasible to recruit and treat multiple myeloma patients with propranolol during HCT, with the greatest obstacle being other competing oncology trials. These data support further studies examining propranolol and other potentially repurposed drugs in oncology populations., Trial Registration: This randomized controlled trial was registered at clinicaltrials.gov with the identifier NCT02420223 on April 17, 2015.

Background: Allogeneic hematopoietic cell transplantation (HCT) cures many patients, but often with the risk of late effects and impaired quality of life. The value of quantifying patient-reported outcomes (PROs) is increasingly being recognized, but the routine collection of PROs is uncommon. This study evaluated the feasibility of prospective PRO collection by an outcome registry at multiple time points from unselected HCT patients undergoing transplantation at centers contributing clinical data to the Center for International Blood and Marrow Transplant Research (CIBMTR), and then it correlated the PRO data with clinical and demographic data., Methods: The Functional Assessment of Cancer Therapy-Bone Marrow Transplant (FACT-BMT), 36-Item Short Form Health Survey (SF-36), and Pediatric Quality of Life Inventory measures were administered before HCT, on day 100, and at 6 and 12 months. Patients were recruited by the transplant center, but posttransplant PRO collection was managed centrally by the CIBMTR., Results: There were 580 eligible patients, and 390 (67%) enrolled. Feasibility was shown by high time-specific retention rates (176 of 238 at 1 year or 74%) and participant satisfaction. Factors associated with higher response rates were an age > 50 years (odds ratio [OR], 1.58; 95% confidence interval [CI], 1.03-2.41; P = .0355), white race (OR, 4.61; 95% CI, 2.66-7.99; P < .0001), and being married (OR, 2.28; 95% CI, 1.42-3.65; P = .0006) for adults and a higher family income for children (OR, 4.99; 95% CI, 2.12-11.75; P = .0002). Importantly, pre-HCT PRO scores independently predicted survival after adjustments for patient-, disease-, and transplant-related factors. The adjusted probabilities of 1-year survival were 56%, 67%, 75%, and 76% by increasing quartiles of the pre-HCT FACT-BMT score and 58%, 72%, 62%, and 82% by increasing quartiles of the pre-HCT SF-36 physical component score., Conclusions: A hybrid model of local consent for centralized PRO collection is feasible, and pretransplant PROs provide critical prognostic information for HCT outcomes.

Atorvastatin administration to both the donors and recipients of matched related donor (MRD) allogeneic hematopoietic cell transplantation (allo-HCT) as acute graft-versus-host disease (GVHD) prophylaxis has been shown to be safe and effective. However, its efficacy as acute GVHD prophylaxis when given only to allo-HCT recipients is unknown. We conducted a phase II study to evaluate the safety and efficacy of atorvastatin-based acute GVHD prophylaxis given only to the recipients of MRD (n = 30) or matched unrelated donor (MUD) (n = 39) allo-HCT, enrolled in 2 separate cohorts. Atorvastatin (40 mg/day) was administered along with standard GVHD prophylaxis consisting of tacrolimus and methotrexate. All patients were evaluable for acute GVHD. The cumulative incidences of grade II to IV acute GVHD at day +100 in the MRD and MUD cohorts were 9.9% (95% confidence interval [CI], 0 to 20%) and 29.6% (95% CI,15.6% to 43.6%), respectively. The cumulative incidences of grade III and IV acute GVHD at day +100 in the MRD and MUD cohorts were 3.4% (95% CI, 0 to 9.7%) and 18.3% (95% CI, 6.3% to 30.4%), respectively. The corresponding rates of moderate/severe chronic GVHD at 1 year were 28.1% (95% CI, 11% to 45.2%) and 38.9% (95% CI, 20.9% to 57%), respectively. In the MRD cohort, the 1-year nonrelapse mortality, relapse rate, progression-free survival, and overall survival were 6.7% (95% CI, 0 to 15.4%), 43.3% (95% CI, 24.9% to 61.7%), 50% (95% CI, 32.1% to 67.9%), and 66.7% (95% CI, 49.8% to 83.6%), respectively. The respective figures for the MUD cohort were 10.3% (95% CI, 8% to 19.7%), 20.5% (95% CI, 7.9% to 33.1%), 69.2% (95% CI, 54.7% to 83.7%), and 79.5% (95% CI, 66.8% to 92.2%), respectively. No grade 4 toxicities attributable to atorvastatin were seen. In conclusion, the addition of atorvastatin to standard GVHD prophylaxis in only the recipients of MRD and MUD allo-HCT appears to be feasible and safe. The preliminary efficacy seen here warrants confirmation in randomized trials., (Copyright © 2017 The American Society for Blood and Marrow Transplantation. Published by Elsevier Inc.

Hematopoietic cell transplantation (HCT) survivors are at risk for development of late complications and require lifelong monitoring for screening and prevention of late effects. There is an increasing appreciation of the issues related to healthcare delivery and coverage faced by HCT survivors. The 2016 National Institutes of Health Blood and Marrow Transplant Late Effects Initiative included an international and broadly representative Healthcare Delivery Working Group that was tasked with identifying research gaps pertaining to healthcare delivery and to identify initiatives that may yield a better understanding of the long-term value and costs of care for HCT survivors. There is a paucity of literature in this area. Critical areas in need of research include pilot studies of novel and information technology supported models of care delivery and coverage for HCT survivors along with development and validation of instruments that capture patient-reported outcomes. Investment in infrastructure to support this research, such as linkage of databases including electronic health records and routine inclusion of endpoints that will inform analyses focused around care delivery and coverage, is required., (Copyright © 2017 The American Society for Blood and Marrow Transplantation.

Blood and Marrow Transplant Clinical Trials Network (BMT CTN) protocol 0902 evaluated whether exercise and stress management training before hematopoietic cell transplantation (HCT) improved physical and mental functioning after HCT. Neither overall survival nor other patient-reported transplantation outcomes were improved by the training intervention. In some animal studies of HCT, moderate-intensity exercise for 8 weeks before HCT has been associated with positive effects on hematopoietic progenitors, resulting in improved donor engraftment and improved survival. Accordingly, we performed a secondary analysis of data from BMT CTN 0902 to determine whether exercise engagement before HCT was associated with engraftment and survival. We found no significant associations between self-reported pre-HCT exercise levels and engraftment or survival. There was also no effect of pretransplantation exercise on either neutrophil or platelet engraftment. These findings do not support the observations in animal models but are limited by several shortcomings that do not refute the hypothesis that exercise before HCT may be beneficial., (Copyright © 2017 The American Society for Blood and Marrow Transplantation.

This secondary analysis of a large, multicenter Blood and Marrow Transplant Clinical Trials Network randomized trial assessed whether patient-reported outcomes (PROs) and socioeconomic status (SES) before hematopoietic stem cell transplantation (HCT) are associated with each other and predictive of clinical outcomes, including time to hematopoietic recovery, acute graft-versus-host disease, hospitalization days, and overall survival (OS) among 646 allogeneic and autologous HCT recipients. Pretransplantation Cancer and Treatment Distress (CTXD), Pittsburgh Sleep Quality Index (PSQI), and mental and physical component scores of the Short-Form 36 were correlated with each other and with SES variables. PROs and SES variables were further evaluated as predictors of clinical outcomes, with the PSQI and CTXD evaluated as OS predictors (P < .01 considered significant given multiple testing). Lower attained education was associated with increased distress (P = .002), lower income was related to worse physical functioning (P = .005) and increased distress (P = .008), lack of employment before transplantation was associated with worse physical functioning (P < .01), and unmarried status was associated with worse sleep (P = .003). In this large heterogeneous cohort of HCT recipients, although PROs and SES variables were correlated at baseline, they were not associated with any clinical outcomes. Future research should focus on HCT recipients at greater psychosocial disadvantage., Competing Interests: Financial disclosure: Conflict of interest statement: There are no conflicts of interest to report., (Copyright © 2016 The American Society for Blood and Marrow Transplantation.

Background: In hematopoietic cell transplantation (HCT), current risk adjustment strategies are based on clinical and disease-related variables. Although patient-reported outcomes (PROs) predict mortality in multiple cancers, they have been less well studied within HCT. Improvements in risk adjustment strategies in HCT would inform patient selection, patient counseling, and quality reporting. The objective of the current study was to determine whether pre-HCT PROs, in particular physical health, predict survival among patients undergoing autologous or allogeneic transplantation., Methods: In this secondary analysis, the authors studied pre-HCT PROs that were reported by 336 allogeneic and 310 autologous HCT recipients enrolled in the Blood and Marrow Transplant Clinical Trials Network (BMT CTN) 0902 protocol, a study with broad representation of patients who underwent transplantation in the United States., Results: Among allogeneic HCT recipients, the pre-HCT Medical Outcomes Study Short Form-36 Health Survey (SF-36) physical component summary (PCS) scale independently predicted overall mortality (hazards ratio, 1.40 per 10-point decrease; P<.001) and performed at least as well as currently used, non-PRO risk indices. Survival probability estimates at 1 year for the first, second, third, and fourth quartiles of the baseline PCS were 50%, 65%, 75%, and 83%, respectively. Early post-HCT decreases in PCS were associated with higher overall and treatment-related mortality. When adjusted for patient variables included in the US Stem Cell Therapeutic Outcomes Database model for transplant center-specific reporting, the SF-36 PCS retained independent prognostic value., Conclusions: PROs have the potential to improve prognostication in HCT. The authors recommend the routine collection of PROs before HCT, and consideration of the incorporation of PROs into risk adjustment for quality reporting., (© 2015 American Cancer Society.)

Prospective validation of the hematopoietic cell transplantation-comorbidity index (HCT-CI) using contemporary patients treated with hematopoietic cell transplantation (HCT) across the Unites States is necessary to confirm its widespread applicability. We performed a prospective observational study including all patients (8115 recipients of allogeneic and 11,652 recipients of autologous HCT) who underwent a first HCT that was reported to the Center for International Blood and Marrow Transplant Research between 2007 and 2009. In proportional hazards models, increased HCT-CI scores were independently associated with increases in hazard ratios for nonrelapse mortality (NRM) (P < .0001) and overall mortality (P < .0001) among recipients of allogeneic HCT. HCT-CI scores of ≥3 were uniformly associated with higher risks for outcomes in both allogeneic and autologous HCT and in all subgroups, regardless of diagnoses, age, and conditioning intensity. Recipients of allogeneic HCT with scores of 1 and 2 who were ages < 18 years or were treated with lower intensity conditioning regimens had similar outcomes compared with those with a score of 0. Higher risks for overall mortality, but not for NRM, were observed among recipients of autologous HCT with scores of 1 and 2 versus 0. Our results confirm the validity the HCT-CI in both allogeneic and autologous HCT. The index should be used as a valid standard-of-care health measure in counseling patients for HCT, in clinical trial design, and in adjusting outcome analyses., (Copyright © 2015 American Society for Blood and Marrow Transplantation.

Hematopoietic cell transplantation (HCT) is a complex procedure that requires availability of adequate infrastructure, personnel, and resources at transplantation centers. We conducted a national survey of transplantation centers in the United States to obtain data on their personnel, infrastructure, and care delivery models. A 42-item web-based survey was administered to medical directors of transplantation centers in the United States that reported any allogeneic HCT to the Center for International Blood and Marrow Transplant Research in 2011. The response rate for the survey was 79% for adult programs (85 of 108 centers) and 82% for pediatric programs (54 of 66 centers). For describing results, we categorized centers into groups with similar volumes based on 2010 total HCT activity (adult centers, 9 categories; pediatric centers, 6 categories). We observed considerable variation in available resources, infrastructure, personnel, and care delivery models among adult and pediatric transplantation centers. Characteristics varied substantially among centers with comparable transplantation volumes. Transplantation centers may find these data helpful in assessing their present capacity and use them to evaluate potential resource needs for personnel, infrastructure, and care delivery and in planning for growth., (Copyright © 2015 American Society for Blood and Marrow Transplantation.

Purpose: The study aims to evaluate the mediating effect of depressive symptoms on the relationship between physical symptoms and health-related quality of life (HRQOL) in hematopoietic stem cell transplant (HSCT) survivors and to test a conceptual model of psychosocial factors, in addition to physical and psychological symptoms, that might contribute to HRQOL., Methods: This is a secondary data analysis using HSCT survivors (N = 662) identified from the Center for International Blood and Marrow Transplant Research. Data were collected through mail and phone surveys and medical records. We used structural equation modeling to test the mediating role of depressive symptoms on the relationship of physical symptoms with HRQOL. We also tested comprehensive pathways from physical symptoms to HRQOL by adding psychosocial factors (optimism, coping, and social constraints)., Results: In the depressive symptom mediation analyses, physical symptoms had a stronger direct effect on physical HRQOL (b = -0.98, p < 0.001) than depressive symptoms (b = 0.23, p > 0.05). Depressive symptoms were associated with mental HRQOL and mediated the relationship between physical symptoms and mental HRQOL. In comprehensive pathways, physical symptoms remained the most significant factor associated with physical HRQOL. In contrast, depressive symptoms had direct effects (b = -0.76, p < 0.001) on mental HRQOL and were a significant mediator. Psychosocial factors were directly associated with mental HRQOL and indirectly associated with mental HRQOL through depressive symptoms., Conclusion: Physical symptoms are most strongly associated with physical HRQOL, while depressive symptoms and psychosocial factors impact mental HRQOL more than physical HRQOL. Interventions addressing psychosocial factors as well as symptoms may improve the HRQOL of HSCT survivors.

Cytokine-based mobilization in light chain (AL) amyloidosis is frequently complicated by fluid overload, weight gain, cardiac arrhythmias, and peri-mobilization mortality. We analyzed hematopoietic progenitor cells (HPC) mobilization outcomes in 49 consecutive AL amyloidosis patients at our institution between 2004 and 2013 with granulocyte colony-stimulating factor (G) (10 μg/kg/day) (n = 25) versus an institutional protocol to limit G exposure using plerixafor (P) (.24 mg/kg s.c. starting day 3 of G 10 μg/kg) (n = 24). G+P strategy yielded higher total CD34(+) cells/kg (12.8 × 10(6) versus 6.3 × 10(6); P < .001) and CD34(+) cells/kg collected on day 1 (10.8 × 10(6) versus 4.9 × 10(6), P = .004) compared with the G cohort. More G+P patients collected ≥5 × 10(6) CD34(+) HPCs/kg (22 versus 16, P = .02) and ≥ 10 × 10(6) CD34(+) HPCs/kg (13 versus 5, P = .01). Four patients (16%) had mobilization failure with G; none with G+P. Peri-mobilization weight gain was lower with G+P strategy (median weight gain 1 versus 7 pounds, P = .009). Numbers of apheresis sessions (median, 1 versus 1, P = .52), number of hospitalization days (median, 1.1 versus 1.6, P = .52), transfusions, use of intravenous antibiotics, and cardiac arrhythmias were similar. In conclusion, our study demonstrates that upfront use of G+P as a mobilization strategy results in superior HPC collection, no mobilization failures, and less weight gain than G alone., (Copyright © 2014 American Society for Blood and Marrow Transplantation.

Studies show that engaging patients in exercise and/or stress management techniques during hematopoietic cell transplantation (HCT) improves quality of life. The Blood and Marrow Transplant Clinical Trials Network tested the efficacy of training patients to engage in self-directed exercise and stress management during HCT. The study randomized 711 patients at 21 centers to receive 1 of 4 training interventions before HCT: a self-directed exercise program, a self-administered stress management program, both, or neither. Participants completed self-reported assessments at enrollment and up to 180 days after HCT. Randomization was stratified by center and transplant type. There were no differences in the primary endpoints of the Physical Component Summary and Mental Component Summary scales of the Medical Outcomes Study Short Form 36 at day +100 among the groups, based on an intention-to-treat analysis. There also were no differences in overall survival, days of hospitalization through day +100 post-HCT, or in other patient-reported outcomes, including treatment-related distress, sleep quality, pain, and nausea. Patients randomized to training in stress management reported more use of those techniques, but patients randomized to training in exercise did not report more physical activity. Although other studies have reported efficacy of more intensive interventions, brief training in an easy-to-disseminate format for either self-directed exercise or stress management was not effective in our trial., (Copyright © 2014 American Society for Blood and Marrow Transplantation.

Background: Hematopoietic stem-cell transplantation (HSCT) is a potentially lifesaving therapy for several blood cancers and other diseases. For patients without a suitable related HLA-matched donor, unrelated-donor registries of adult volunteers and banked umbilical cord-blood units, such as the Be the Match Registry operated by the National Marrow Donor Program (NMDP), provide potential sources of donors. Our goal in the present study was to measure the likelihood of finding a suitable donor in the U.S. registry., Methods: Using human HLA data from the NMDP donor and cord-blood-unit registry, we built population-based genetic models for 21 U.S. racial and ethnic groups to predict the likelihood of identifying a suitable donor (either an adult donor or a cord-blood unit) for patients in each group. The models incorporated the degree of HLA matching, adult-donor availability (i.e., ability to donate), and cord-blood-unit cell dose., Results: Our models indicated that most candidates for HSCT will have a suitable (HLA-matched or minimally mismatched) adult donor. However, many patients will not have an optimal adult donor--that is, a donor who is matched at high resolution at HLA-A, HLA-B, HLA-C, and HLA-DRB1. The likelihood of finding an optimal donor varies among racial and ethnic groups, with the highest probability among whites of European descent, at 75%, and the lowest probability among blacks of South or Central American descent, at 16%. Likelihoods for other groups are intermediate. Few patients will have an optimal cord-blood unit--that is, one matched at the antigen level at HLA-A and HLA-B and matched at high resolution at HLA-DRB1. However, cord-blood units mismatched at one or two HLA loci are available for almost all patients younger than 20 years of age and for more than 80% of patients 20 years of age or older, regardless of racial and ethnic background., Conclusions: Most patients likely to benefit from HSCT will have a donor. Public investment in donor recruitment and cord-blood banks has expanded access to HSCT.

Because the outcome of allogeneic hematopoietic cell transplantation (HCT) is predominantly influenced by disease type and status, it is essential to be able to stratify patients undergoing HCT by disease risk. The Disease Risk Index (DRI) was developed for this purpose. In this study, we analyzed 13,131 patients reported to the Center for International Blood and Marrow Transplant Research who underwent HCT between 2008 and 2010. The DRI stratified patients into 4 groups with 2-year overall survival (OS) ranging from 64% to 24% and was the strongest prognostic factor, regardless of age, conditioning intensity, graft source, or donor type. A randomly selected training subgroup of 9849 patients was used to refine the DRI, using a multivariable regression model for OS. This refined DRI had improved prediction ability for the remaining 3282 patients compared with the original DRI or other existing schemes. This validated and refined DRI can be used as a 4- or 3-group index, depending on the size of the cohort under study, for prognostication; to facilitate the interpretation of single-center, multicenter, or registry studies; to adjust center outcome data; and to stratify patients entering clinical trials that enroll patients across disease categories., (© 2014 by The American Society of Hematology.)

Advances in hematopoietic cell transplantation (HCT) technology and supportive care techniques have led to improvements in long-term survival after HCT. Emerging indications for transplantation, introduction of newer graft sources (eg, umbilical cord blood) and transplantation of older patients using less intense conditioning regimens have also contributed to an increase in the number of HCT survivors. These survivors are at risk for developing late complications secondary to pre-, peri-, and posttransplantation exposures and risk factors. Guidelines for screening and preventive practices for HCT survivors were published in 2006. An international group of transplantation experts was convened in 2011 to review contemporary literature and update the recommendations while considering the changing practice of transplantation and international applicability of these guidelines. This review provides the updated recommendations for screening and preventive practices for pediatric and adult survivors of autologous and allogeneic HCT.

We conducted a prospective cohort study testing the noninferiority of survival of ablative intravenous busulfan (IV-BU) vs ablative total body irradiation (TBI)-based regimens in myeloid malignancies. A total of 1483 patients undergoing transplantation for myeloid malignancies (IV-BU, N = 1025; TBI, N = 458) were enrolled. Cohorts were similar with respect to age, gender, race, performance score, disease, and disease stage at transplantation. Most patients had acute myeloid leukemia (68% IV-BU, 78% TBI). Grafts were primarily peripheral blood (77%) from HLA-matched siblings (40%) or well-matched unrelated donors (48%). Two-year probabilities of survival (95% confidence interval [CI]), were 56% (95% CI, 53%-60%) and 48% (95% CI, 43%-54%, P = .019) for IV-BU (relative risk, 0.82; 95% CI, 0.68-0.98, P = .03) and TBI, respectively. Corresponding incidences of transplant-related mortality (TRM) were 18% (95% CI, 16%-21%) and 19% (95% CI, 15%-23%, P = .75) and disease progression were 34% (95% CI, 31%-37%) and 39% (95% CI, 34%-44%, P = .08). The incidence of hepatic veno-occlusive disease (VOD) was 5% for IV-BU and 1% with TBI (P < .001). There were no differences in progression-free survival and graft-versus-host disease. Compared with TBI, IV-BU resulted in superior survival with no increased risk for relapse or TRM. These results support the use of myeloablative IV-BU vs TBI-based conditioning regimens for treatment of myeloid malignancies.

Allogeneic hematopoietic cell transplantation (HCT) from human leukocyte antigen (HLA) matched related donor (MRD) and matched unrelated donors (MUD) produces similar survival for patients with acute myelogenous leukemia. Whether these results can be extended to patients with myelodysplastic syndromes (MDS) is unknown. Therefore, analysis of post-HCT outcomes for MDS was performed. Outcomes of 701 adult MDS patients who underwent HCT between 2002 and 2006 were analyzed (MRD [n = 176], 8 of 8 HLA-A, -B, -C, -DRB1 allele matched MUD [n = 413], 7 of 8 MUD [ n = 112]). Median age was 53 years (range, 22-78 years). In multivariate analyses, MRD HCT recipients had similar disease free survival (DFS) and survival rates compared with 8 of 8 MUD HCT recipients (relative risk [RR] 1.13 [95% confidence interval (CI) 0.91-1.42] and 1.24 [95% CI 0.98-1.56], respectively), and both MRD and 8 of 8 MUD had superior DFS (RR 1.47 [95% CI 1.10-1.96] and 1.29 [95% CI 1.00-1.66], respectively) and survival (RR 1.62 [95% CI 1.21-2.17] and 1.30 [95% CI 1.01-1.68], respectively) compared with 7 of 8 MUD HCT recipients. In patients with MDS, MRD remains the best stem cell source followed by 8 of 8 MUD. Transplantation from 7 of 8 MUD is associated with significantly poorer outcomes.

Advances in hematopoietic cell transplantation (HCT) have led to an increasing number of transplant survivors. However, long-term survival is challenged by late relapse, late complications and late non-relapse mortality, and HCT survivors need continued lifelong surveillance for screening, early detection and timely treatment of late complications such as secondary cancers, late infections and organ toxicity. Guidelines for screening and preventive practices for pediatric and adult survivors of autologous and allogeneic HCT were updated and published in 2012. However, several barriers to the care of HCT survivors and routine utilization of these guidelines in clinical practice exist. Examples include paucity of and challenges to conducting prospective randomized trials for screening and prevention of late complications, lack of resources to manage late effects at the level of transplant centers and community health care providers, and inadequate tools to facilitate care and followup of HCT survivors. We summarize the long-term followup guidelines in this review, discuss ways that providers can integrate and utilize them for the care of their patients, and identify areas for research that can inform and increase the utilization of screening and prevention guidelines in clinical practice.

Purpose: Over the past four decades, allogeneic hematopoietic cell transplantation (alloHCT) has evolved as a curative modality for patients with hematologic diseases. This study describes changes in use, technique, and survival in a population-based cohort., Patients and Methods: The study included 38,060 patients with hematologic malignancies or disorders who underwent first alloHCT in a US or Canadian center from 1994 to 2005 and were reported to the Center for International Blood and Marrow Transplant Research., Results: AlloHCT as treatment for acute lymphoblastic (ALL) and myeloid leukemias (AML), myelodysplastic syndrome (MDS), and Hodgkin and non-Hodgkin lymphomas increased by 45%, from 2,520 to 3,668 patients annually. From 1994 to 2005, use of both peripheral (7% to 63%) [corrected] and cord blood increased (2% to 10%), whereas use of marrow decreased (90% to 27%). Despite a median age increase from 33 to 40 years and 165% [corrected] increase in unrelated donors for alloHCT, overall survival (OS) at day 100 significantly improved for patients with AML in first complete remission after myeloablative sibling alloHCT (85% to 94%; P < .001) and unrelated alloHCT (63% to 86%; P < .001); 1-year OS improved among those undergoing unrelated alloHCT (48% to 63%; P = .003) but not among those undergoing sibling alloHCT. Similar results were seen for ALL and MDS. Day-100 OS after cord blood alloHCT improved significantly from 60% to 78% (P < .001) for AML, ALL, MDS, and chronic myeloid leukemia. Use of reduced-intensity regimens increased, yielding OS rates similar to those of myeloablative regimens., Conclusion: Survival for those undergoing alloHCT has significantly improved over time. However, new approaches are needed to further improve 1-year OS.

Autologous hematopoietic cell transplantation (auto-HCT) is performed to treat relapsed and recurrent malignant disorders and as part of initial therapy for selected malignancies. This study evaluated changes in use, techniques, and survival in a population-based cohort of 68,404 patients who underwent first auto-HCT in a US or Canadian center between 1994 and 2005 and were reported to the Center for International Blood and Marrow Transplant Research (CIBMTR). The mean annual number of auto-HCTs performed was highest during 1996-1999 (6948), and decreased subsequently 2000-2003 (4783), owing mainly to fewer auto-HCTs done to treat breast cancer. However, the mean annual number of auto-HCTs increased from 5278 annually in 1994-1995 to 5459 annually in 2004-2005, reflecting increased use for multiple myeloma, non-Hodgkin lymphoma, and Hodgkin lymphoma. Despite an increase in the median recipient age from 44 to 53 years, there has been a significant improvement in overall survival (OS) from 1994 to 2005 in patients with chemotherapy-sensitive relapsed non-Hodgkin lymphoma (day +100 OS, from 85% to 96%; 1-year OS, from 68% to 80%; P < .001) and chemotherapy-sensitive multiple myeloma (day +100 OS, from 96% to 98%; 1-year OS, from 83% to 92%; P < .001). This improvement in OS was most pronounced in middle-aged (>40 years) and older (>60 years) individuals., (Copyright © 2013 American Society for Blood and Marrow Transplantation.

African Americans and Blacks have low participation rates in clinical trials and reduced access to aggressive medical therapies. Hematopoietic cell transplantation (HCT) is a high-risk but potentially curative therapy for sickle cell disease (SCD), a disorder predominantly seen in African Americans. We conducted focus groups to better understand participation barriers to HCT clinical trials for SCD. Nine focus groups of youth with SCD (n=10) and parents (n=41) were conducted at 3 sites representing the Midwest, South Atlantic, and West South Central US. Main barriers to clinical trial participation included gaps in knowledge about SCD, limited access to SCD/HCT trial information, and mistrust of medical professionals. For education about SCD/HCT trials, participants highly preferred one-on-one interactions with medical professionals and electronic media as a supplement. Providers can engage with sickle cell camps to provide information on SCD/HCT clinical trials to youth and local health fairs for parents/families. Youth reported learning about SCD through computer games; investigators may find this medium useful for clinical trial/HCT education. African Americans affected by SCD face unique barriers to clinical trial participation and have unmet HCT clinical studies education needs. Greater recognition of these barriers will allow targeted interventions in this community to increase their access to HCT.

We studied graft-versus-host disease (GVHD) on relapse, transplant-related mortality (TRM), disease-free survival (DFS), and overall survival (OS) after allogeneic transplantation for acute myelogenous leukemia (AML) (n = 4224) and myelodysplastic syndrome (MDS) (n = 1517) in 4 groups: without GVHD, acute GVHD (aGVHD) alone, chronic GVHD (cGVHD) alone, and aGVHD + cGVHD. Examining GVHD as a time-dependent covariate, after myeloablative conditioning (MAC), cGVHD and aGVHD + cGVHD were associated with lower relapse (P < .002). TRM was higher in all GVHD groups (P < .0001); DFS and OS were lower with aGVHD ± cGVHD (P < .0001). After reduced-intensity conditioning (RIC), relapse was lower in all GVHD groups (P < .0001); TRM was increased and DFS and OS were reduced with any GVHD (P < .0001). In those surviving disease-free (≥1-year) after MAC, relapse risks were similar in all groups and TRM was higher with any GVHD (P < .0001). DFS and OS were lower with cGVHD and aGVHD + cGVHD (P < .0006). After RIC, relapse was lower (P = .009) and TRM higher (P = .002) only with aGVHD + cGVHD. DFS was similar in all groups and OS worse with aGVHD + cGVHD. After MAC, GVHD has an adverse effect on TRM with early modest augmentation of GVHD-associated graft-versus-leukemia (GVL). With RIC, GVHD-associated GVL may be important in limiting both early and late leukemia recurrence., (Copyright © 2012 American Society for Blood and Marrow Transplantation.

Despite prophylaxis with immunosuppressive agents or a variety of other approaches, many patients suffer from acute graft-versus-host disease (aGVHD) after allogeneic hematopoietic cell transplantation. Although consensus has emerged supporting the use of high-dose methylprednisolone or prednisone for initial treatment of aGVHD, practices differ among centers with respect to the initial glucocorticoid dose, the use of additional immunosuppressive agents, and the approach to withdrawal of treatment after initial improvement. Despite many studies, practices vary considerably with respect to the selection of agents for treatment of glucocorticoid-resistant or refractory GVHD. Investigators and clinicians have recognized the lack of progress and lamented the absence of an accepted standard of care for secondary treatment of aGVHD. The American Society of Blood and Marrow Transplantation has developed recommendations for treatment of aGVHD to be considered by care providers, based on a comprehensive and critical review of published reports. Because the literature provides little basis for a definitive guideline, this review also provides a framework for the interpretation of previous results and the design of future studies., (Copyright © 2012 American Society for Blood and Marrow Transplantation.

Adolescents and young adults (AYAs) with cancer have not experienced improvements in survival to the same extent as children and older adults. We compared outcomes among children (<15 years), AYAs (15-40 years) and older adults (>40 years) receiving allogeneic hematopoietic cell transplant (HCT) for acute myeloid leukemia (AML). Our cohort consisted of 900 children, 2,708 AYA, and 2,728 older adult recipients of HLA-identical sibling or unrelated donor (URD) transplantation using myeloablative or reduced-intensity/nonmyeloablative conditioning. Outcomes were assessed over three time periods (1980-1988, 1989-1997, 1998-2005) for siblings and two time periods (1989-1997, 1998-2005) for URD HCT. Analyses were stratified by donor type. Results showed overall survival for AYAs using either siblings or URD improved over time. Although children had better and older adults had worse survival compared with AYAs, improvements in survival for AYAs did not lag behind those for children and older adults. After sibling donor HCT, 5-year adjusted survival for the three time periods was 40%, 48%, and 53% for children, 35%, 41%, and 42% for AYAs, and 22%, 30%, and 34% for older adults. Among URD HCT recipients, 5-year adjusted survival for the two time periods was 38% and 37% for children, 24% and 28% for AYAs, and 19% and 23% for older adults. Improvements in survival occurred because of a reduction in risk of treatment-related mortality. The risk of relapse did not change over time. Improvements in survival among AYAs undergoing allogeneic HCT for AML have paralleled those among children and older adults., (Copyright © 2012 American Society for Blood and Marrow Transplantation.

Approximately one-third of patients with an indication for hematopoietic cell transplantation (HCT) have an HLA-matched related donor (MRD) available to them. For the remaining patients, a matched unrelated donor (MUD) is an alternative. Prior studies comparing MRD and MUD HCT provide conflicting results, and the relative efficacy of MRD and MUD transplantation is an area of active investigation. To address this issue, we analyzed outcomes of 2223 adult acute myelogenous leukemia patients who underwent allogeneic HCT between 2002 and 2006 (MRD, n = 624; 8/8 HLA locus matched MUD, n = 1193; 7/8 MUD, n = 406). The 100-day cumulative incidence of grades B-D acute GVHD was significantly lower in MRD HCT recipients than in 8/8 MUD and 7/8 MUD HCT recipients (33%, 51%, and 53%, respectively; P < .001). In multivariate analysis, 8/8 MUD HCT recipients had a similar survival rate compared with MRD HCT recipients (relative risk [RR], 1.03; P = .62). 7/8 MUD HCT recipients had higher early mortality than MRD HCT recipients (RR, 1.40; P < .001), but beyond 6 months after HCT, their survival rates were similar (RR, 0.88; P = .30). These results suggest that transplantation from MUD and MRD donors results in similar survival times for patients with acute myelogenous leukemia.

Advances in hematopoietic cell transplantation (HCT) technology and supportive care techniques have led to improvements in long-term survival after HCT. Emerging indications for transplantation, introduction of newer graft sources (eg, umbilical cord blood) and transplantation of older patients using less intense conditioning regimens have also contributed to an increase in the number of HCT survivors. These survivors are at risk for developing late complications secondary to pre-, peri-, and posttransplantation exposures and risk factors. Guidelines for screening and preventive practices for HCT survivors were published in 2006. An international group of transplantation experts was convened in 2011 to review contemporary literature and update the recommendations while considering the changing practice of transplantation and international applicability of these guidelines. This review provides the updated recommendations for screening and preventive practices for pediatric and adult survivors of autologous and allogeneic HCT., (Copyright © 2012.

With greater numbers of patients surviving long-term after allogeneic stem cell transplantation (SCT), second malignancies have increasingly been recognized. Secondary solid tumors, the most prevalent second malignancies after allogeneic SCT, are reviewed with particular emphasis on recent developments in the pathogenesis, early diagnosis, and treatment of these transplant-related complications., (Copyright © 2012 Elsevier Inc.

Shortage of manpower and center capacity is expected to be a major challenge to the anticipated future growth in the utilization of allogeneic hematopoietic cell transplantation (HCT) in the United States. Using data from the National Marrow Donor Program's Transplant Center Network Renewal Survey, we describe transplant center and transplant physician capacity in the United States from 2005 to 2009. Over this 5-year period, the number of allogeneic transplants increased by 30%, bed capacity increased by 17%, and physician full-time equivalents increased by 26%. The number of related donor HCT increased by 15% and unrelated donor HCT increased by 45%. In addition to large centers, small- and medium-sized centers also made a major contribution to overall national transplant volumes for both related and unrelated donor HCT. Increase in utilization of unrelated donor HCT occurred in centers irrespective of their size. The majority of transplant centers were performing more transplantations using existing physician and bed capacity. Our study provides important descriptions of allogeneic transplant activity and capacity of U.S. centers, and our data will assist policy makers plan for the projected growth in the use of transplantation., (2011 American Society for Blood and Marrow Transplantation.

Purpose: Allogeneic hematopoietic cell transplantation (HCT) is curative but is associated with life-threatening complications. Most deaths occur within the first 2 years after transplantation. In this report, we examine long-term survival in 2-year survivors in the largest cohort ever studied., Patients and Methods: Records of 10,632 patients worldwide reported to the Center for International Blood and Marrow Transplant Research who were alive and disease free 2 years after receiving a myeloablative allogeneic HCT before 2004 for acute myelogenous or lymphoblastic leukemia, myelodysplastic syndrome, lymphoma, or severe aplastic anemia were reviewed., Results: Median follow-up was 9 years, and 3,788 patients had been observed for 10 or more years. The probability of being alive 10 years after HCT was 85%. The chief risk factors for late death included older age and chronic graft-versus-host disease (GVHD). For patients who underwent transplantation for malignancy, relapse was the most common cause of death. The greatest risk factor for late relapse was advanced disease at transplantation. Principal risk factors for nonrelapse deaths were older age and GVHD. When compared with age, sex, and nationality-matched general population, late deaths remained higher than expected for each disease, with the possible exception of lymphoma, although the relative risk generally receded over time., Conclusion: The prospect for long-term survival is excellent for 2-year survivors of allogeneic HCT. However, life expectancy remains lower than expected. Performance of HCT earlier in the course of disease, control of GVHD, enhancement of immune reconstitution, less toxic regimens, and prevention and early treatment of late complications are needed.

Purpose: Transplantation-related mortality (TRM) is a major barrier to the success of allogeneic hematopoietic cell transplantation (HCT)., Patients and Methods: We assessed changes in the incidence of TRM and overall survival from 1985 through 2004 in 5,972 patients younger than age 50 years who received myeloablative conditioning and HCT for acute myeloid leukemia (AML) in first complete remission (CR1) or second complete remission (CR2)., Results: Among HLA-matched sibling donor transplantation recipients, the relative risks (RRs) for TRM were 0.5 and 0.3 for 2000 to 2004 compared with those for 1985 to 1989 in patients in CR1 and CR2, respectively (P < .001). The RRs for all causes of mortality in the latter period were 0.73 (P = .001) and 0.60 (P = .005) for the CR1 and CR2 groups, respectively. Among unrelated donor transplantation recipients, the RRs for TRM were 0.73 (P = .095) and 0.58 (P < .001) for 2000 to 2004 compared with those in 1990 to 1994 in the CR1 and CR2 groups, respectively. Reductions in mortality were observed in the CR2 group (RR, 0.74; P = .03) but not in the CR1 group., Conclusion: Our results suggest that innovations in transplantation care since the 1980s and 1990s have reduced the risk of TRM in patients undergoing allogeneic HCT for AML and that this reduction has been accompanied by improvements in overall survival.

Preservation of fertility after hematopoietic cell transplantation (HCT) can have a significant influence on the quality of life of transplant survivors. We describe 178 pregnancies in HCT recipients that were reported to the Center for International Blood and Marrow Transplant Research (CIBMTR) between 2002 and 2007. There were 83 pregnancies in female HCT recipients and 95 pregnancies in female partners of male HCT recipients. Indications for transplantation included hematologic and other malignancies (N = 99) and nonmalignant disorders (N = 79, of which 75 patients had severe aplastic anemia). The cohort included recipients of autologous HCT (20 women, 13 men), myeloablative (MA) allogeneic HCT (12 women, 50 men), and nonmyeloablative allogeneic HCT (2 women, 2 men). Age at HCT was <20 years for 50% of women and 19% of men. Conditioning regimens included total body irradiation (TBI) in 16% of women and 19% of men; doses were MA in 10% of women and in 16% of men. Live births were reported in 86% of pregnancies in partners of male transplant patients and 85% of pregnancies in female transplant patients, with most pregnancies occurring 5 to 10 years after HCT. We conclude that some HCT recipients can retain fertility, including patients who have received TBI and/or MA conditioning. Young patients undergoing HCT should be counseled both before and after HCT about potential loss of fertility, methods for preserving fertility, and planning for future pregnancy. Fertility and outcomes of pregnancy after HCT need prospective evaluation in large transplant cohorts., (Copyright © 2011 American Society for Blood and Marrow Transplantation.

Mucopolysaccharidosis VI (MPS VI, Maroteaux-Lamy Syndrome) is one of approximately 50 known lysosomal storage disorders. MPS VI is characterized by an absence or deficiency of N-acetylgalactosamine 4-sulfatase (arylsulfatase B) resulting in accumulation of dermatan sulfate. Prior to the availability of enzyme replacement therapy (ERT), the clinical management of MPS VI was limited to supportive care and allogeneic hematopoietic stem cell transplantation (HSCT); however, due to the rarity of this disease, little is known about the long-term outcomes of HSCT for MPS VI. The following retrospective study was performed using aggregate data gathered by the Center for International Blood and Marrow Transplant Research (CIBMTR) between 1982 and 2007 to determine survival probability for patients with MPS VI following allogeneic HSCT. This analysis identified 45 MPS VI patients with a median age of 5 years (range, 1-22 years) at the time they received an allogeneic HSCT. Cumulative incidence (95% CI) of acute graft-vs.-host disease at 100 days was 36% (21-53%). Probability of survival was 78% (65-89%) at 100 days and 66% (52-79%) at 1 and 3 years. While these data are based upon small numbers of recipients, they represent the largest series to date and may help clinicians assess the relative risks and benefits of currently available therapies., (Copyright © 2010 Elsevier Inc.

Risks of secondary solid cancers among allogeneic hematopoietic cell transplant (HCT) recipients who receive conditioning without total body irradiation are not well known. We evaluated the incidence and risk factors for solid cancers after HCT using high-dose busulfan-cyclophosphamide conditioning in 4318 recipients of first allogeneic HCT for acute myeloid leukemia in first complete remission (N = 1742) and chronic myeloid leukemia in first chronic phase (N = 2576). Our cohort represented 22 041 person-years at risk. Sixty-six solid cancers were reported at a median of 6 years after HCT. The cumulative-incidence of solid cancers at 5 and 10 years after HCT was 0.6% and 1.2% among acute myeloid leukemia and 0.9% and 2.4% among chronic myeloid leukemia patients. In comparison to general population incidence rates, HCT recipients had 1.4× higher than expected rate of invasive solid cancers (95% confidence interval, 1.08-1.79, P = .01). Significantly elevated risks were observed for tumors of the oral cavity, esophagus, lung, soft tissue, and brain. Chronic graft-versus-host disease was an independent risk factor for all solid cancers, and especially cancers of the oral cavity. Recipients of allogeneic HCT using busulfan-cyclophosphamide conditioning are at risk for developing solid cancers. Their incidence continues to increase with time, and lifelong cancer surveillance is warranted in this population.
