RESUMEN
The Center for International Blood and Marrow Transplant Research (CIBMTR) prepares an annual set of summary slides to summarize the trends in transplantation and cellular therapies. For the first time in the 2023 summary slides, the CIBMTR incorporated data for patients receiving chimeric antigen receptor T cell (CAR-T) infusions. In addition, data on patient-reported outcomes (PROs) are included. This report aims to update the annual trends in US hematopoietic cell transplantation (HCT) activity and incorporate data on the use of CAR-T therapies. A second aim is to present and describe the development, implementation, and current status of PRO data collection. In August 2020, the CIBMTR launched the Protocol for Collection of Patient-Reported Outcomes Data (CIBMTR PRO Protocol). The CIBMTR PRO Protocol operates under a centralized infrastructure to reduce the burden to centers. Specifically, PRO data are collected from a prospective convenience sample of adult HCT and CAR-T recipients who received treatment at contributing centers and consented for research. Data are merged and stored with the clinical data and used under the governance of the CIBMTR Research Database Protocol. Participants answer a series of surveys developed by the Patient Reported Outcomes Measurement Information System (PROMIS) focusing on physical, social and emotional, and other measures assessing financial well-being, occupational functioning, and social determinants of health. To complement traditionally measured clinical outcomes, the surveys are administered at the same time points at which clinical data are routinely collected. As of September 2023, PRO data have been collected from 993 patients across 25 different centers. With the goal of incorporating these important patient perspectives into standard clinical care, the CIBMTR has added the PRO data to Data Back to Centers (DBtC). Through expanding the data types represented in the registry, the CIBMTR aims to support holistic research accounting for the patients' perspective in improving patient outcomes. CIBMTR PRO data aim to provide a foundation for future large-scale, population-level evaluations to identify areas for improvement, emerging disparities in access and health outcomes (eg, by age, race, and ethnicity), and new therapies that may impact current treatment guidelines. Continuing to collect and grow the PRO data is critical for understanding these changes and identifying methods for improving patients' quality of life.

ABSTRACT: Allogeneic hematopoietic cell transplantation is a life-saving procedure used to treat a variety of devastating diseases. It requires hematopoietic stem cells collected via filgrastim-mobilized peripheral blood stem cells (PBSCs) or bone marrow (BM) harvest from volunteer unrelated donors (URDs). There is a paucity of safety data regarding donors' long-term adverse events. This prospective, observational study combined PBSC donors enrolled in the NMDP Investigational New Drug trial and BM donors between 1 July 1999 and 30 September 2015. The primary objective was to describe the long-term incidence of myeloid malignancies. The secondary objectives included describing the long-term incidence of lymphoid malignancies, nonhematologic malignancies, autoimmune disorders, and thrombotic events. A total of 21 643 donors (14 530 PBSCs and 7123 BM) were included. The incidence rate of myeloid disorders per 100 000 person-years in donors of PBSCs was 2.53 (95% confidence interval [CI], 0.82-7.84) and in donors of BM, it was 4.13 (95% CI, 1.33-12.8). The incidence rate ratio of PBSCs/BM donors was 0.61 (95% CI, 0.12-3.03; P = .55). The incidence of other malignancies, autoimmunity, and thrombosis did not differ between the donor types. This comprehensive study of the long-term effects of filgrastim in URDs of PBSCs provides strong evidence that donors who receive filgrastim are not at an increased risk of these events compared with BM donors. It also provides reassurance to current donors undergoing stem cell mobilization as well as individuals considering joining stem cell registries, such as NMDP.

Young adults from underserved racial/ethnic groups are critically needed as unrelated hematopoietic stem cell (HSC) donors, yet they are more likely than other groups to opt out of donation after having matched a patient. Understanding which factors are most strongly associated with opting out among young underserved racial/ ethnic registered donors compared with their White counterparts will provide the basis for specific interventions to improve donor retention. We sought to determine the key, modifiable psychosocial, registry-related, and donation-related characteristics that are uniquely associated with opting out across 5 key racial/ethnic groups of young HSC donor registry members who had been contacted as a potential match for a patient. This study examines data from a large cross-sectional survey of young (age 18 to 30) registry members shortly after they preliminarily matched a patient (CT-stage) and continued toward or opted out of donation (CT-C and CT-NI), stratified by racial/ethnic group and sex. We assessed psychosocial, registry-related, and donation-related characteristics for all participants. We used chi-squared and F tests to assess differences between racial/ethnic groups. A separate logistic regression analysis for each racial/ethnic group was conducted to quantify adjusted associations between each variable and opting out. Then, we compared these associations across the racial/ethnic groups by evaluating the interaction effect between each variable and racial/ethnic group, with the same outcome (CT-C versus CT-NI) in question. Nine hundred thirty-five participants were surveyed, including 284 White, 165 Hispanic, 191 Black, 192 Asian/Pacific Islander, and 103 Multiracial/multiethnic participants. There were significant differences across racial/ethnic groups in values/goals, religious objections to donation, HSC-related medical mistrust, and parental involvement in donation decisions. Adjusted logistic regression subgroup analyses indicated that ambivalence was strongly associated with opting out across all racial/ethnic groups. Greater focus on intrinsic life goals (e.g., raising a family, becoming a community leader, influencing social values) was associated with opting out in the Multiracial/multiethnic, Hispanic, and Asian/Pacific Islander groups. Healthcare mistrust and insufficient registry contact was a significant factor for Hispanic participants. Protective factors against opting out included remembering joining the registry (Black participants), and parental support for donation decision (Asian/Pacific Islander participants). The performance of each logistic regression model was strong, with area-under-the curve ≥.88, CT-stage outcome classification accuracy ≥89%, and good fit between expected and observed opt-out probabilities. In the analysis across different racial/ethnic groups, the only significant interaction was race/ethnicity by whether more contact with the registry would have changed the decision at CT-stage; this variable was significant only for the Hispanic group. In the within-group analysis for Hispanic participants, the "more registry contact" variable was strongly associated with opting out (odds ratio 5.8, P = .03). Consistent with a growing body of HSC donor research, ambivalence was a key factor associated with opting-out for all racial/ethnic groups. Other key variables were differentially associated with opting-out depending on racial/ethnic group. Our study highlights key variables that registries should focus on as they develop targeted and tailored strategies to enhance commitment and reduce attrition of potential donors.

BACKGROUND: The Center for International Blood and Marrow Transplant Research (CIBMTR) provides a 1-year overall survival calculator to estimate outcomes for individual patients before they undergo allogeneic hematopoietic cell transplantation (HCT) to inform risk. The calculator considers pre-HCT clinical and demographic characteristics, but not patient-reported outcomes (PROs). Because pre-HCT PRO scores have been associated with post-HCT outcomes, the authors hypothesized that adding PRO scores to the calculator would enhance its predictive power. METHODS: Clinical data were obtained from the CIBMTR and the Blood and Marrow Transplant Clinical Trials Network. The PRO measures used were the 36-Item Short Form Survey (SF-36) and the Functional Assessment of Cancer Therapy-Bone Marrow Transplantation. One thousand thirty-three adult patients were included. RESULTS: When adjusted for clinical characteristics, the SF-36 physical component score was significantly predictive of 1-year survival (hazard ratio [HR], 0.88; 95% confidence interval [CI], 0.81-0.95; p = .0015), whereas the mental component score was not (HR, 1.02; 95% CI, 0.95-1.10; p = 0.6396). The baseline single general health question on the SF-36 was also significantly associated with mortality (HR, 1.91 for those reporting fair/poor health vs. good, very good, or excellent health; 95% CI, 1.33-2.76; p = .0005). The addition of PRO scores to the calculator did not result in a significant change in the model's predictive ability. Self-reported pre-HCT scores were strongly predictive of self-reported health status (odds ratio, 3.35; 95% CI, 1.66-6.75; p = .0007) and quality of life (odds ratio, 3.24; 95% CI, 1.93-5.41; p < .0001) after HCT. CONCLUSIONS: The authors confirmed the significant, independent association of pre-HCT PRO scores with overall survival, although adding PRO scores to the survival calculator did not improve its performance. They also demonstrated that a single general health question was as accurate as the full measure for predicting survival, an important finding that may reduce respondent burden and promote its inclusion in routine clinical practice. Validation of these findings should be performed.

Palliative care (PC) benefits patients undergoing hematopoietic stem cell transplantation (HSCT), but it remains underutilized. Although transplant physicians report concerns regarding how patients perceive PC, HSCT recipients' perceptions about PC remain unaddressed. We conducted a multisite, cross-sectional survey of autologous and allogeneic HSCT recipients 3 to 12 months after transplant to assess their familiarity, knowledge, and perception of PC, as well as their unmet PC needs. We computed a composite score of patients' perceptions of PC and used a generalized linear regression model to examine factors associated with these perceptions. We enrolled 69.6% (250/359) of potential participants (median age = 58.1; 63.1% autologous HSCT). Overall, 44.3.8% (109/249) reported limited knowledge about PC and 52% (127/245) endorsed familiarity with PC. Most patients felt hopeful (54%) and reassured (50%) when they heard the term PC; 83% saw referral as a sign their doctor cared about what was happening to them. In multivariate analyses, patients who were more knowledgeable about PC were more likely to have positive perceptions of PC (B = 7.54, standard error = 1.61, P < .001). Patients' demographics, HSCT features, quality of life, and symptom burden were not significantly associated with perceptions of PC. HSCT recipients have positive perceptions of PC, though many have limited knowledge about its role. Patients who were more knowledgeable about PC were more likely to have positive perceptions of PC. These data do not support transplant physicians' negative concerns about how patients perceive PC and underscore the need to further educate patients and transplant physicians about PC.

Young adults enrolled in hematopoietic stem cell (HSC) donation registries, including the Be The Match registry in the United States, often opt out of the registry when a potential recipient is identified. This results in a limited supply from the most desirable allogeneic source of HSCs used in transplantation to treat serious health conditions. The differences in demographic, psychosocial, registry-related, and donation-related characteristics between those who continue to donation and those who opt out may elucidate the modifiable risk factors for attrition, but these characteristics have not been extensively studied in young donors up to age 30 years. Our goal was to study demographic, psychosocial, registry-related, and donation-related characteristics in a group of young HSC donor registry members who had recently been contacted about a potential recipient, to determine the key characteristics that differ between those who continued toward donation and those who opted out and to examine the extent of these differences. We conducted a cross-sectional survey in a random sample of young (age 18 to 30 years) current and former registry members, stratified by race/ethnicity and sex. Demographic, psychosocial (eg, life goals, HSC allocation mistrust), registry-related (eg context and motive for joining the registry), and donation-related (eg, ambivalence, religious objections to donation, knowledge about donation) characteristics were assessed. Chi-square and 2-sample t tests were used to examine differences between those who continued (CT-C group) and those who opted out (CT-NI group). Hierarchical logistic regression was used to estimate adjusted covariate effects on the odds of opting out. A total of 935 participants were surveyed. Donation-related knowledge was higher in the CT-C group than in the CT-NI group. HSC allocation mistrust, religious objections, and concerns about donation were higher in the CT-NI group. After adjusting for covariates in a logistic regression model, we found that having more intrinsic life goals, having more ambivalence, and talking with registry staff only once/twice were significantly associated with opting out of the registry. Ambivalence had the strongest association with opting out. In contrast, remembering joining the registry, believing that parents would support donation, and having medical concerns were significantly associated with continuing toward donation. This effect of medical concerns on donation was discovered only after adjusting for the related but distinct ambivalence variable, with the remaining effect of medical concerns relating to engagement with the donation process and information-seeking. The model had strong discriminative ability (area under the receiver operating characteristic curve = .92) and classification accuracy (86.6%). Our data indicate that among young adult members of a national HSC donor registry, ambivalence and limited contact with registry staff were more strongly associated with opting out of donation. Medical concerns were associated with continuing toward donation. Further studies are needed to confirm a causal link between medical concerns and continuing to donation among young donors. Our study suggests that these concerns might not be directly related to attrition, whereas other factors (eg, ambivalence, low donation-related knowledge) are associated with attrition and thus should be targeted for attrition reduction strategies.

Attrition of young adult registry members is a significant issue impacting hematopoietic stem cell (HSC) donation registries, including the Be The Match registry in the US. The resulting limited supply of allogeneic HSCs, used to treat serious health conditions, has a stronger impact on racial/ethnic minority groups in the US. Compared with young white adults, young adults identifying with these minority groups are more likely to drop out of the donor registry when called to donate. However, the underlying psychosocial factors that differ between white and nonwhite registrants have not been fully investigated. The central goal of this study was to examine demographic, registry-related, and donation-related characteristics in a young, newly registered group of potential donors and to determine whether these characteristics differed by, or were distributed differently among, racial/ethnic groups. We conducted a cross-sectional survey in a random sample of young (age 18 to 30 years) newly registered members, stratified by racial/ethnic group and sex. Demographic, registry-related (eg, context and motive for joining the registry), and donation-related (eg, ambivalence, religious objections to donation, knowledge about donation) characteristics were assessed. The chi-square test and analysis of variance were used to examine differences among racial/ethnic groups. Discriminant function analysis was used to assess whether patterns of the 3 classes of characteristics were associated with membership in particular racial/ethnic groups. A total of 524 participants were surveyed. Joining online was most common among white individuals, whereas joining at college was most common among black and Hispanic individuals. Ambivalence toward donation was higher among Asian/Pacific Islanders compared with white or multiracial/multiethnic individuals. Discriminant function analysis revealed 4 psychosocial/attitudinal functions predicting membership in certain racial/ethnic groups. The function accounting for the most variance in responses included mistrust of HSC allocation, religious objections to donation, low parental support, and low knowledge level. This function discriminated significantly between the white and nonwhite groups. Another function also identified ambivalence as a discriminating factor, which was most strongly associated with Asian/Pacific Islanders. Among young adult members of an HSC donor registry, such factors as ambivalence, family concerns about donation, mistrust of HSC allocation, religious objections, and less knowledge about donation were more strongly associated with membership in the nonwhite groups compared with the white group. These factors are known to be associated with a higher risk of opting out after having been preliminarily matched with a patient. The finding that these characteristics are associated with racial/ethnic minority group membership provides targets for recruitment strategies aimed at improving retention of young registry members.

The importance of patient-reported outcomes (PROs) in cellular therapies, including hematopoietic cell transplantation (HCT) is highlighted in this study. Longitudinal collection of PROs in a registry is recommended for several reasons, yet to date, PROs are not routinely collected from HCT patients to augment clinical registry data. The aim of this study was to determine the feasibility of electronic PRO data collection by a national clinical outcomes registry, by assessing differences between who does and does not report PROs. We conducted a cross-sectional pilot collection of PROs from HCT recipients after treatment using computer-adapted tests from the Patient-Reported Outcome Measurement Information System (PROMIS). We implemented centralized data collection through the Center for International Blood and Marrow Transplant Research (CIBMTR) among patients who underwent HCT for myelodysplastic syndromes (MDS), were at least 6 months post-HCT, and spoke English or Spanish. The main objective was identifying patient, disease, and transplant-related differences associated with completion of electronic PROs. Patients were excluded from analysis if they were determined to be ineligible (deceased, did not speak English or Spanish, refused to be contacted by the CIBMTR). A total of 163 patients were contacted and potentially eligible to participate; of these, 92 (56%) enrolled and 89 (55%) completed the PRO assessment. The most frequent reason for incomplete surveys was inability to contact patients (n = 88), followed by declining to participate in the study (n = 37). There were no sociodemographic or age differences between those who completed the PRO survey (n = 89) and eligible nonresponders (n = 155). Patient scores were within 3 points of the US average of 50 for all symptoms and functioning except physical functioning. Responders and nonresponders did not exhibit meaningfully different sociodemographic characteristics. Difficulty contacting patients posed the greatest barrier and also provided the greatest opportunity for improvement. Once enrolled, survey completion was high. These results support standardizing centralized PRO data collection through the CIBMTR registry.

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.

Survivorship Care Plans (SCPs) may facilitate long-term care for cancer survivors, but their effectiveness has not been established in hematopoietic cell transplantation recipients. We evaluated the impact of individualized SCPs on patient-reported outcomes among transplant survivors. Adult (≥18 years at transplant) survivors who were 1-5 years post transplantation, proficient in English, and without relapse or secondary cancers were eligible for this multicenter randomized trial. SCPs were developed based on risk-factors and treatment exposures using patient data routinely submitted by transplant centers to the Center for International Blood and Marrow Transplant Research and published guidelines for long-term follow up of transplant survivors. Phone surveys assessing patient-reported outcomes were conducted at baseline and at 6 months. The primary end point was confidence in survivorship information, and secondary end points included cancer and treatment distress, knowledge of transplant exposures, health care utilization, and health-related quality of life. Of 495 patients enrolled, 458 completed a baseline survey and were randomized (care plan=231, standard care=227); 200 (87%) and 199 (88%) completed the 6-month assessments, respectively. Patients' characteristics were similar in the two arms. Participants on the care plan arm reported significantly lower distress scores at 6 months and an increase in the Mental Component Summary quality of life score assessed by the Short Form 12 (SF-12) instrument. No effect was observed on the end point of confidence in survivorship information or other secondary outcomes. Provision of individualized SCPs generated using registry data was associated with reduced distress and improved mental domain of quality of life among 1-5 year hematopoietic cell transplantation survivors. Trial registered at clinicaltrials.gov 02200133.

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.
