A Positive Psychology Intervention in Allogeneic Hematopoietic Stem Cell Transplantation Survivors (PATH): A Pilot Randomized Clinical Trial.

BACKGROUND: Allogeneic hematopoietic stem cell transplantation (HSCT) survivors experience significant psychological distress and low levels of positive psychological well-being, which can undermine patient-reported outcomes (PROs), such as quality of life (QoL). Hence, we conducted a pilot randomized clinical trial to assess the feasibility and preliminary efficacy of a telephone-delivered positive psychology intervention (Positive Affect for the Transplantation of Hematopoietic stem cells intervention [PATH]) for improving well-being in HSCT survivors. METHODS: HSCT survivors who were 100 days post-HSCT for hematologic malignancy at an academic institution were randomly assigned to either PATH or usual care. PATH, delivered by a behavioral health expert, entailed 9 weekly phone sessions on gratitude, personal strengths, and meaning. We defined feasibility a priori as >60% of eligible participants enrolling in the study and >75% of PATH participants completing ≥6 of 9 sessions. At baseline and 9 and 18 weeks, patients self-reported gratitude, positive affect, life satisfaction, optimism, anxiety, depression, posttraumatic stress disorder (PTSD), QoL, physical function, and fatigue. We used repeated measures regression models and estimates of effect size (Cohen's d) to explore the preliminary effects of PATH on outcomes. RESULTS: We enrolled 68.6% (72/105) of eligible patients (mean age, 57 years; 50% female). Of those randomized to PATH, 91% completed all sessions and reported positive psychology exercises as easy to complete and subjectively useful. Compared with usual care, PATH participants reported greater improvements in gratitude (ß = 1.38; d = 0.32), anxiety (ß = -1.43; d = -0.40), and physical function (ß = 2.15; d = 0.23) at 9 weeks and gratitude (ß = 0.97; d = 0.22), positive affect (ß = 2.02; d = 0.27), life satisfaction (ß = 1.82; d = 0.24), optimism (ß = 2.70; d = 0.49), anxiety (ß = -1.62; d = -0.46), depression (ß = -1.04; d = -0.33), PTSD (ß = -2.50; d = -0.29), QoL (ß = 7.70; d = 0.41), physical function (ß = 5.21; d = 0.56), and fatigue (ß = -2.54; d = -0.33) at 18 weeks. CONCLUSIONS: PATH is feasible, with promising signals for improving psychological well-being, QoL, physical function, and fatigue in HSCT survivors. Future multisite trials that investigate PATH's efficacy are needed to establish its effects on PROs in this population.

Comparison of treatment response measures in cutaneous sclerosis after allogeneic hematopoietic cell transplantation.

Cutaneous sclerosis, a highly morbid subtype of chronic graft vs. host disease (cGVHD), demonstrates limited treatment response under current NIH Response Measures. We explored novel sclerosis-specific response measures using Chronic GVHD Consortium data. A training cohort included patients with cutaneous sclerosis from a randomized trial of imatinib vs. rituximab, and a Consortium observational study. The validation cohort was a different Consortium observational study. Clinician-reported measures (baseline, and baseline to 6-month change) were examined for association with 6-month clinician-reported response. Patient-reported measures (baseline and baseline to 6-month change) were studied for association with 6-month patient-reported response. A total of 347 subjects were included (training 183, validation 164). While multiple skin and joint measures were associated with clinician-reported response on univariate analysis, PROM total score, PROM total score change, and NIH 0-3 skin change were retained in the final multivariate model (AUC 0.83 training, 0.75 validation). Similarly, many patient-reported measures were associated, but final multivariate analysis retained the HAP AAS, SF36 vitality change, LSS skin, and LSS skin change in the model (AUC 0.86 training, 0.75 validation). We identified which sclerosis measures have greatest association with 6-month clinician- and patient-reported treatment response, a previously unstudied area. However, given the observed performance in the validation cohorts, we conclude that further work is needed. Novel response measures may be needed to optimally assess treatment response in cutaneous sclerosis.

Leveraging Hematopoietic Cell Transplant Data and Biorepository Resources at the Center for International Blood and Marrow Transplant Research to Improve Patient Outcomes.

BACKGROUND: Hematopoietic cell transplantation (HCT) has undergone many advances over the decades. Trends in HCT utilization have been impacted by research based on the data and samples collected by the Center for International Blood and Marrow Transplant Research (CIBMTR). OBJECTIVE: Here, we provide a summary report of the CIBMTR Biorepository resource and describe the biospecimen inventory along with collection and request procedures. STUDY DESIGN: The diversity captured in this inventory reflects transplant activity, and these samples can be leveraged for secondary analyses to generate more data and insights to advance the field. RESULTS: We describe how our resources have already impacted HCT practice and elaborate on possibilities for further collaboration and utilization to maximize capabilities and research opportunities. CONCLUSION: Hematopoietic cell transplant data and Biorepository resources at the Center for International Blood and Marrow Transplant Research have been and continue to be leveraged to improve patient outcomes.

Hemophagocytic Lymphohistiocytosis Gene Variants in Severe Aplastic Anemia and Their Impact on Hematopoietic Cell Transplantation Outcomes.

Germline genetic testing for patients with severe aplastic anemia (SAA) is recommended to guide treatment, including the use of immunosuppressive therapy and/or adjustment of hematopoietic cell transplantation (HCT) modalities. Hemophagocytic lymphohistiocytosis (HLH) is a life-threatening hyperinflammatory condition often associated with cytopenias with autosomal recessive (AR) or X-linked recessive (XLR) inheritance. HLH is part of the SAA differential diagnosis, and genetic testing may identify variants in HLH genes in patients with SAA. The impact of pathogenic/likely pathogenic (P/LP) variants in HLH genes on HCT outcomes in SAA is unclear. In this study, we aimed to determine the frequency of HLH gene variants in a large cohort of patients with acquired SAA and to evaluate their association(s) with HCT outcomes. The Transplant Outcomes in Aplastic Anemia project, a collaboration between the National Cancer Institute and the Center for International Blood and Marrow Transplant Research, collected genomic and clinical data from 824 patients who underwent HCT for SAA between 1989 and 2015. We excluded 140 patients with inherited bone marrow failure syndromes and used exome sequencing data from the remaining 684 patients with acquired SAA to identify P/LP variants in 14 HLH-associated genes (11 AR, 3 XLR) curated using American College of Medical Genetics and Genomics/Association of Molecular Pathology (ACMG/AMP) criteria. Deleterious variants of uncertain significance (del-VUS) were defined as those not meeting the ACMG/AMP P/LP criteria but with damaging predictions in ≥3 of 5 meta-predictors (BayesDel, REVEL, CADD, MetaSVM, and/or EIGEN). The Kaplan-Meier estimator was used to calculate the probability of overall survival (OS) after HCT, and the cumulative incidence calculator was used for other HCT outcomes, accounting for relevant competing risks. There were 46 HLH variants in 49 of the 684 patients (7.2%). Seventeen variants in 19 patients (2.8%) were P/LP; 8 of these were loss-of-function variants. Among the 19 patients with P/LP HLH variants, 16 (84%) had monoallelic variants in genes with AR inheritance, and 3 had variants in XLR genes. PRF1 was the most frequently affected gene (in 8 of the 19 patients). We found no statistically significant differences in transplantation-related factors between patients with and those without P/LP HLH variants. The 5-year survival probability was 89% (95% confidence interval [CI], 72% to 99%) in patients with P/LP HLH variants and 70% (95% CI, 53% to 85%) in those with del-VUS HLH variants, compared to 66% (95% CI, 62% to 70%) in those without variants (P = .16, log-rank test). The median time to neutrophil engraftment was 16 days for patients with P/LP HLH variants and 18 days in those with del-VUS HLH variants or without variants combined (P = .01, Gray's test). No statistically significant associations between P/LP HLH variants and the risk of acute or chronic graft-versus-host disease were noted. In this large cohort of patients with acquired SAA, we found that 2.8% of patients harbored a P/LP variant in an HLH gene. No negative effects of HLH gene variants on post-HCT survival were noted. The small number of patients with P/LP HLH variants limits the study's ability to provide conclusive evidence; nonetheless, our data suggest that there is no need for special transplantation considerations for patients with SAA carrying P/LP variants.

Study protocol: Close Assessment and Testing for Chronic Graft-vs.-Host disease (CATCH).

Chronic graft-versus-host disease (GVHD) is an immune-mediated disorder that causes significant late morbidity and mortality following allogeneic hematopoietic cell transplantation. The "Close Assessment and Testing for Chronic GVHD (CATCH)" study is a multi-center Chronic GVHD Consortium prospective, longitudinal cohort study designed to enroll patients before hematopoietic cell transplantation and follow them closely to capture the development of chronic GVHD and to identify clinical and biologic biomarkers of chronic GVHD onset. Data are collected pre-transplant and every two months through one-year post-transplant with chart review thereafter. Evaluations include clinician assessment of chronic GVHD and its manifestations, patient-reported outcomes, multiple biospecimens (blood, saliva, tears, buccal mucosa and fecal samples, biopsies of skin and mouth), laboratory testing, and medical record abstraction. This report describes the rationale, design, and methods of the CATCH study, and invites collaboration with other investigators to leverage this resource. trial registration: This study is registered at www.clinicaltrials.gov as NCT04188912.

Racial, Ethnic and Socioeconomic Diversity and Outcomes of Patients with Graft-versus-Host Disease: A CIBMTR Analysis.

Socioeconomic status (SES) and race/ethnicity have been associated with outcomes of allogeneic hematopoietic cell transplantation (allo-HCT). Certain aspects of GVHD management such as the need for long term care, prolonged immunosuppressive treatment, and need for close follow up for complications may exacerbate disparities. Adults (≥ 18 years) reported to the Center for International Blood and Marrow Transplant Research (CIBMTR) who underwent a first alloHCT for acute leukemia, myelodysplastic syndrome, or myeloproliferative neoplasm between 2008 - 2018 were included. Endpoints for those developing GVHD included overall survival (OS), transplant related mortality (TRM), and disease relapse. Models were adjusted for patient and transplant related variables. A two-sided p-value < 0.01 was considered significant. Among the 14,825 allo-HCT recipients, 6,259 (42.2%) and 6,675 (45.0%) patients developed aGVHD and cGVHD, respectively. In patients with aGVHD, non-Hispanic Blacks had increased TRM (HR 1.50, 95% CI 1.24-1.83, p=0.0001) and overall mortality (HR 1.31, 1.14-1.50, p=0.0002) compared with non-Hispanic Whites, an association that disappeared when severity of aGVHD was included in the model. Lower SES was associated with increased risk of disease relapse (p=0.0016) but not OS or TRM. In patients who developed cGVHD, race and ethnicity were not associated with OS, TRM and disease relapse. However, the highest quartile of annual household income (≥ $80,000) had improved OS (HR 0.77, 0.69-0.85, p<0.0001) and reduced TRM (HR 0.86, 0.67-0.87, p<0.0001) compared with lowest quartile, adjusting for race and ethnicity. Race/ethnicity and SES are associated with outcomes after GVHD. Optimizing health care resources available to low SES patients and strategies to minimize the risk of severe GVHD in non-Hispanic Blacks may improve long-term outcomes.

Intensive Reinduction Chemotherapy Followed by Early Allogeneic Hematopoietic Cell Transplantation for Relapsed/Refractory High-Grade Myeloid Neoplasms.

Outcomes for adults with relapsed/refractory (R/R) high-grade myeloid neoplasms remain poor, with allogeneic hematopoietic cell transplantation (HCT) the sole therapy likely to result in cure. We conducted the present study to determine the feasibility of early HCT-within 60 days of beginning reinduction chemotherapy-to see whether getting patients to HCT in an expeditious manner would expand the number of patients being offered this curative option. In this proof-of-principle feasibility study, we included adults age 18 to 75 years with R/R myeloid malignancies with ≥10% blood/marrow blasts at diagnosis who were eligible for a reduced-intensity HCT. Subjects received reinduction chemotherapy with cladribine, cytarabine, mitoxantrone, and filgrastim (CLAG-M) and proceeded to HCT with reduced-intensity conditioning (fludarabine/ melphalan). We enrolled 30 subjects, all of whom received CLAG-M reinduction, although only 9 underwent HCT within 60 days (<15, the predetermined threshold for feasibility "success"), with a median time to HCT of 48 days (range, 42 to 60 days). Eleven additional subjects received HCT beyond the target 60 days (off-study), with a median time to transplantation of 83 days (range, 53 to 367 days). Barriers to early HCT included infection, physician preference, lack of an HLA-matched donor, logistical delays, and disease progression, all of which may limit the real-world uptake of such early-to-transplantation protocols.

Donor whole blood DNA methylation is not a strong predictor of acute graft versus host disease in unrelated donor allogeneic haematopoietic cell transplantation.

Allogeneic hematopoietic cell transplantation (HCT) is used to treat many blood-based disorders and malignancies, however it can also result in serious adverse events, such as the development of acute graft-versus-host disease (aGVHD). This study aimed to develop a donor-specific epigenetic classifier to reduce incidence of aGVHD by improving donor selection. Genome-wide DNA methylation was assessed in a discovery cohort of 288 HCT donors selected based on recipient aGVHD outcome; this cohort consisted of 144 cases with aGVHD grades III-IV and 144 controls with no aGVHD. We applied a machine learning algorithm to identify CpG sites predictive of aGVHD. Receiver operating characteristic (ROC) curve analysis of these sites resulted in a classifier with an encouraging area under the ROC curve (AUC) of 0.91. To test this classifier, we used an independent validation cohort (n = 288) selected using the same criteria as the discovery cohort. Attempts to validate the classifier failed with the AUC falling to 0.51. These results indicate that donor DNA methylation may not be a suitable predictor of aGVHD in an HCT setting involving unrelated donors, despite the initial promising results in the discovery cohort. Our work highlights the importance of independent validation of machine learning classifiers, particularly when developing classifiers intended for clinical use.

Returning to Work Following Hematopoietic Cell Transplantation: The Survivor's Perspective.

While curing a patient's underlying disease is the primary goal of physicians performing hematopoietic cell transplantation (HCT), the ultimate objective is to provide patients with optimal post-HCT quality of life. For many survivors, this includes returning to work (RTW). We conducted a survey of 1- to 5-yr post-HCT survivors at our center to evaluate their perspective on facilitators and barriers to RTW as well as to gauge interest in potentially useful RTW support interventions. Survivors aged 18 to 65 yrs (n = 994) were sent an annual survey that included 36 supplementary questions about post-HCT RTW. Survey questions were selected from published national cancer survivor surveys and then modified specifically for HCT survivors. Three hundred forty-four (35%) survivors with a mean age of 53 yrs completed the survey, of whom 272 (79%) had worked prior to their diagnosis. Of those 272 patients, 145 (53%) were working currently and another 22 (8%) had attempted to go back to work following HCT but were not presently working. We found that having had an allogeneic versus autologous HCT (P = .006) was associated with a decreased likelihood of currently working, whereas frequent employer communication (>once a month) (P = .070) and having a more supportive employer (P = .036) were associated with a greater chance of currently working. Of survivors currently working, 45% reported that they had made one or more changes to their work schedule (e.g., flexible schedule or part-time work) or environment (e.g., work from home) upon RTW. Ninety-five percent of responders reported that they could have benefited from RTW support provided by the transplant center, but only 13% indicated that they had received it. Education on RTW challenges, information on disability benefits, and access to physical therapy were among the most requested support interventions. To improve post-HCT quality of life for survivors open to assistance, providers should address work status and goals, recognize barriers to successful return, and offer RTW support including working directly with employers. Allogeneic HCT survivors are particularly vulnerable to failing attempts to RTW and should be the target of retention interventions. A previously published manuscript on RTW guidance for providers of stem cell transplant patients endorsed by the American Society of Transplant and Cellular Therapy is available in Open Access and can be used as a tool to counsel and support these patients.

Financial Toxicity, Time Toxicity, and Quality of Life in Multiple Myeloma.

BACKGROUND: Patients with multiple myeloma (MM) may be on therapy for years, which can lead to financial toxicity (FinTox) or time toxicity (TimeTox). The prevalence, predictors, and quality of life (QOL) impacts of FinTox and TimeTox during different phases of MM treatment have not been characterized. PATIENTS AND METHODS: We conducted a single-center cross-sectional survey of patients with MM who had undergone transplantation. FinTox+ was defined as a COST-FACIT score <23, TimeTox+ as MM-related interactions (including phone calls) ≥1x weekly or ≥1x monthly in-person among far-residing patients, QOL using PROMIS Global Health, and functional status using patient-reported Karnofsky performance status (KPS). RESULTS: Of 252 patients, 22% and 40% met FinTox+ and TimeTox+ criteria respectively. Respective FinTox+ and TimeTox+ proportions were 22%/37% for patients on maintenance, 22%/82% with active therapy, and 20%/14% with observation. FinTox+ predictors included annual income (P < .01) and out-of-pocket costs (P < .01). TimeTox+ predictors included disease status (P < .001), caregiver status (P = .01), far-residing status (P < .001), and out-of-pocket costs (P = .03). FinTox+ was associated with a clinically meaningful decrease in mental QOL, while TimeTox+ patients were more likely to have KPS ≤ 80. CONCLUSIONS: In our large study, monetary status but not disease status predicted FinTox. Over a third of patients on maintenance reported TimeTox. FinTox+ was associated with decreased mental health, while TimeTox+ was associated with worse performance status. These two toxicities may negatively impact patient wellbeing, and studies of strategies to mitigate their impact are in development.

Combined effect of unrelated donor age and HLA peptide-binding motif match status on HCT outcomes.

ABSTRACT: An HLA-mismatched unrelated donor who is class I peptide-binding motif (PBM)-matched is preferred over a PBM-mismatched donor. We hypothesized that using a younger donor (aged ≤35 years vs >35 years) could compensate for the inferior overall survival (OS) associated with PBM mismatches. We compared 6 groups: HLA-matched/younger donor (n = 10 531), HLA-matched/older donor (n = 3572), PBM-matched/younger donor (n = 357), PBM-matched/older donor (n = 257), PBM-mismatched/younger donor (n = 616), and PBM-mismatched/older donor (n = 339) in patients undergoing transplantation with conventional graft-versus-host disease prophylaxis. In multivariate analysis, HLA-matched/younger donors were associated with superior OS relative to any other group. Pairwise comparisons showed that donor age significantly impacted OS in both HLA-matched and HLA-mismatched groups. Moreover, younger donors appeared to negate the detrimental effect of PBM mismatching: the PBM-matched/younger donor group had similar OS as the HLA-matched/older donor group and the PBM-mismatched/younger donor group had similar OS as the PBM-matched/older donor group. Our study suggests that older unrelated donor age and PBM mismatching confer similarly adverse effects on OS and the impacts are additive, a finding which may widen the "acceptable" donor pool. The best OS is observed with HLA-matched/younger donors and the worst with PBM-mismatched/older donors. These findings should be validated with other data sets and with posttransplantation cyclophosphamide-based prophylaxis.

Late Cytomegalovirus Disease after Hematopoietic Cell Transplantation: Significance of Novel Transplantation Techniques.

Pre-emptive therapy (PET) and letermovir prophylaxis are effective in preventing CMV disease within the first 100 days after allogeneic hematopoietic cell transplantation (HCT) but are associated with late-onset CMV disease. We retrospectively examined the clinical manifestations, risk factors, prevention algorithm, and outcome of late CMV disease in CMV seropositive day 100 survivors transplanted between 2001-2017 (PET cohort) and 2018-2021 (letermovir cohort). There were 187 episodes of late CMV disease among 2469 day 100 survivors and the estimated cumulative incidence of first late CMV disease was 6.7% (95% CI 5.6-%-7.6%) with no difference between the PET 6.7% (95% CI 5.7%-7.8%) and the letermovir group 5.4% (95% CI 3.2%-8.3%). 32 (1.3%) patients had a second episode of late CMV disease. In multivariable Cox regression models, post-transplant cyclophosphamide was associated with an increased risk of gastrointestinal CMV disease. CMV viremia detected before day 100, corticosteroid treatment after day 100 at dose ≥1mg/kg, acute and chronic GvHD, lymphopenia, HLA mismatched related donors status and recipient age were also associated with late CMV disease. HLA mismatched donor status and late use of corticosteroids (≥1 mg/kg) were risk factors for late CMV disease recurrence. Late CMV disease occurred most frequently in a setting of prolonged low-level untreated viremia and was independently associated with death by year two after HCT. In summary, late CMV disease continues to occur in the current era. Improved prevention strategies for late CMV disease are needed.

Patient-Reported Outcomes and Mortality in Cutaneous Chronic Graft-vs-Host Disease.

Importance: Chronic graft-vs-host disease (GVHD) is associated with impaired quality of life and symptom burden. The independent association of skin involvement with patient-reported outcomes (PROs) and their utility as a clinical prognostic marker remain unknown. Identification of patients with cutaneous chronic GVHD and impaired PROs could assist in initial risk stratification and treatment selection. Objective: To compare the association of sclerotic and epidermal-type chronic GVHD with longitudinal PROs and to evaluate whether PROs can identify patients with cutaneous chronic GVHD at high risk for death. Design, Setting, and Participants: This multicenter prospective cohort study involved patients from the Chronic GVHD Consortium of 9 US medical centers, enrolled between August 2007 and April 2012, and followed up until December 2020. Participants included adults 18 years and older with a diagnosis of chronic GVHD requiring systemic immunosuppression and with skin involvement during the study period. Main Outcomes and Measures: Patient-reported symptom burden was assessed using the Lee Symptom Scale (LSS) skin subscale with higher scores indicating worse outcomes. Quality of life was measured using the Functional Assessment of Cancer Therapy-Bone Marrow Transplantation (FACT-BMT) instrument with lower scores indicating worse outcomes. Nonrelapse mortality, overall survival, and their association with PROs at diagnosis were also assessed. Results: Among 436 patients with cutaneous chronic GVHD (median [IQR] age at transplant, 51 [41.5-56.6] years; 261 [59.9%] male), 229 patients had epidermal-type chronic GVHD (52.5%), followed by 131 with sclerotic chronic GVHD (30.0%), and 76 with combination disease (17.4%). After adjusting for confounders, patients with sclerotic chronic GVHD had mean FACT-BMT scores 6.1 points worse than those with epidermal disease (95% CI, 11.7-0.4; P = .04). Patients with combination disease had mean LSS skin subscale scores 9.0 points worse than those with epidermal disease (95% CI, 4.2-13.8; P < .001). Clinically meaningful differences were defined as at least 7 points lower for FACT-BMT and 11 points higher for LSS skin subscale. At diagnosis, clinically meaningful worsening in FACT-BMT score was associated with an adjusted odds of nonrelapse mortality increased by 9.1% (95% CI, 2.0%-16.7%; P = .01). Similarly, for clinically meaningful worsening in LSS skin subscale score, adjusted odds of nonrelapse mortality increased by 16.4% (95% CI, 5.4%-28.5%; P = .003). These associations held true after adjusting for clinical severity by the National Institutes of Health Skin Score. Conclusions and Relevance: The results of this cohort study demonstrated that skin chronic GVHD was independently associated with long-term PRO impairment, with sclerotic and combination disease carrying the highest morbidity. The degree of impairment at skin chronic GVHD diagnosis was a prognostic marker for mortality. Therefore, PROs could be useful for risk stratification and treatment selection in clinical practice and clinical trials.

Gratitude, optimism, and satisfaction with life and patient-reported outcomes in patients undergoing hematopoietic stem cell transplantation.

OBJECTIVE: Associations between positive psychological well-being (PPWB) and patient-reported outcomes (PROs, e.g., quality of life [QOL]) have yet to be studied extensively in patients with hematologic malignancies who are allogeneic hematopoietic stem cell transplant (HSCT) survivors, despite substantial evidence that PPWB impacts PROs of other medical populations. METHODS: We conducted a secondary analysis of cross-sectional data examining the association of PPWB and PROs at day 100 post-transplant among 158 allogeneic HSCT recipients. Optimism, gratitude, life satisfaction, and PROs (i.e., QOL, anxiety, depression, and PTSD symptoms) were assessed using the Life Orientation Test-Revised, Gratitude Questionnaire, Satisfaction with Life Scale, Functional Assessment of Cancer Therapy-Bone Marrow Transplant, Hospital Anxiety and Depression Scale, and Post-Traumatic Stress Disorder (PTSD) Checklist-Civilian Version, respectively. We used linear and multivariate regressions for all analyses and controlled for patient factors. RESULTS: Optimism was associated with better QOL (ß = 1.46; p < 0.001) and lower levels of anxiety (ß = -0.28; p < 0.001), depression (ß = -0.31; p < 0.001), and PTSD (ß = -0.58; p < 0.001). Gratitude was associated with better QOL (ß = 1.11; p < 0.001) and lower levels of anxiety (ß = -0.21; p = 0.001), depression (ß = -0.14; p = 0.021), and PTSD (ß = -0.32; p = 0.032). Finally, satisfaction with life was associated with better QOL (ß = 1.26; p < 0.001) and lower levels of anxiety (ß = -0.18; p < 0.001), depression (ß = -0.21; p < 0.001), and PTSD (ß = -0.49; p < 0.001). CONCLUSION: Optimism, gratitude, and satisfaction with life were all associated with better QOL and lower levels of psychological distress in allogeneic HSCT survivors. These data support studies to harness PPWB as a therapeutic intervention for this population throughout HSCT recovery.

Incorporating patient-reported outcome data into a predictive calculator for allogeneic hematopoietic cell transplantation recipients.

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.

Protocol for multi-site randomized trial of inpatient palliative care for patients with hematologic malignancies undergoing hematopoietic stem cell transplantation.

BACKGROUND: Patients with hematologic malignancies undergoing hematopoietic stem cell transplantation (HSCT) commonly experience debilitating physical and psychological symptoms during a 3-4-week-hospitalization. During hospitalization, caregivers (i.e., family and friends) also endure immense emotional stress as they witness their loved one struggle with HSCT toxicities. Yet interventions to improve quality of life (QOL) and reduce psychological distress during HSCT are limited. METHODS: We are conducting a multi-site randomized controlled trial of inpatient integrated palliative and transplant care versus usual care in 360 patients hospitalized for HSCT and their caregivers at three academic centers. Intervention participants meet with a palliative care clinician at least twice weekly during the HSCT hospitalization to address their physical and psychological symptoms. Patients assigned to usual care receive all supportive care measures provided by the HSCT team and could be seen by palliative care upon request. We assess patient QOL (Functional Assessment of Cancer Therapy (FACT) - Bone Marrow Transplant), depression and anxiety symptoms (Hospital Anxiety and Depression Scale), post-traumatic stress (PTSD) symptoms (PTSD checklist), symptom burden (Edmonton Symptom Assessment Scale), and fatigue (FACT-Fatigue) as well as caregiver-reported outcomes at baseline, 2 weeks, 3-months, 6-months, and 12-months post-HSCT. The primary endpoint is to compare QOL at week-2 during HSCT hospitalization between the two groups when patients typically experience their QOL nadir during HSCT. CONCLUSIONS: This multi-site trial will define the role of palliative care for improving QOL and care for patients with hematologic malignancies undergoing HSCT and their caregivers.

A Positive Psychology Intervention for Caregivers of Hematopoietic Stem Cell Transplantation Survivors (PATH-C): Initial Testing and Single-Arm Pilot Trial.

Caregivers of patients with hematologic malignancies undergoing allogeneic hematopoietic stem cell transplantation (HSCT) play a crucial role in supporting their loved ones through physical, emotional, and practical challenges. This role has been associated with high levels of psychological distress and low levels of positive psychological well-being (PPWB). Positive psychology interventions for caregivers in other disease groups (eg, breast cancer) have been associated with improved outcomes. However, positive psychology interventions that specifically address HSCT caregivers' psychological needs are currently lacking. The goal of this single-arm open-pilot trial was to determine the feasibility and acceptability of the Positive Affect in the Transplantation of Hematopoietic Stem Cells (PATH) intervention for HSCT Caregivers to identify caregiver preferences to tailor PATH for HSCT caregivers. Adult caregivers of HSCT recipients were eligible for PATH during the HSCT recipient's first 100 d post-transplant. We defined, a priori, feasibility as >60% of participants who start the intervention completing ≥6/9 intervention sessions and acceptability as weekly ratings of ease and utility of the PP exercises ≥7/10 on a 10-point Likert Scale (0 = very difficult/not helpful; 10 = very easy/very helpful). We conducted semistructured qualitative exit interviews (n = 15) to explore HSCT caregivers' perception of PATH's content, benefits of PATH, as well as facilitators and barriers to engaging with the intervention. Transcribed interviews were analyzed using framework-guided rapid analysis by 2 coders. The intervention was feasible with 83% (15/18) of caregivers who started the intervention completing ≥6/9 intervention sessions. Among caregivers who completed ≥6/9 intervention sessions, ratings of ease (mean = 8.1; 95% CI: 7.4, 8.7) and utility (mean = 8.3; 95% CI: 7.8, 8.9) also exceeded our a priori threshold of ≥7/10. Caregivers identified benefits of PATH, including identifying and responding to emotions, dedicating time to self-care, and cultivating important relationships. Sociodemographic factors (eg, being retired) and the manualized structure of PATH were cited as facilitators to intervention engagement. Barriers to PATH engagement included lack of time and competing caregiving responsibilities. Caregivers preferred remote intervention delivery within the first 100 d post HSCT. This is the first study to show a 9-wk, phone-delivered positive psychology intervention is feasible in caregivers of allogeneic HSCT recipients. Our findings also underscore the specific preferences of this population for positive psychology interventions. Larger studies are warranted to establish the efficacy of these interventions in addressing persistent unmet psychological needs for HSCT caregivers.

Coping in patients with hematologic malignancies undergoing hematopoietic cell transplantation.

ABSTRACT: Patients undergoing hematopoietic cell transplantation (HCT) must cope with physical and psychological symptoms. Yet, studies examining pre-HCT coping are limited. We aimed to characterize pre-HCT coping, evaluate the association of coping with baseline quality of life (QOL) and psychological distress, and identify sociodemographic factors associated with pre-HCT coping. We conducted a cross-sectional analysis of baseline data from a multisite randomized supportive care intervention trial among patients with hematologic malignancies undergoing allogeneic or autologous HCT. We assessed patient-reported QOL, psychological distress, and coping within 72 hours of admission for HCT. We used the median split method to dichotomize coping and multivariate regression analyses to characterize the association of coping with psychological distress and QOL. Of patients awaiting HCT (n = 360; mean age, 55.4 years; 49.7% autologous), 43.5% were high users of approach-oriented coping, whereas 31.3% were high users of avoidant coping. Patients reported high use of emotional support (60.9%), acceptance (51.2%), self-blame (33%), and denial (31.3%). Older age (≥65 years) was associated with less frequent use of avoidant coping (odds ratio, 0.5; P = .01). Approach-oriented coping was associated with better pre-HCT QOL (Beta(B) = 6.7; P = .001), and lower depression (B = -1.1; P = .001) and anxiety (B = -0.9; P = .02) symptoms. Avoidant coping was associated with worse pre-HCT QOL (B = -13.3; P < .001) and symptoms of depression (B = 1.9; P < .001), anxiety (B = 3.1; P < .001), and posttraumatic stress disorder (B = 8.1; P < .001). Pre-HCT coping is strongly associated with psychological distress and QOL. These data support the need for interventions to address coping during HCT hospitalization. This clinical trial was registered at www.clinicaltrials.gov as #NCT03641378.

Severity of Chronic Graft-versus-Host Disease and Late Effects Following Allogeneic Hematopoietic Cell Transplantation for Adults with Hematologic Malignancy.

The study aimed to determine the association of chronic graft-versus-host disease (cGVHD) diagnosis and severity with the development of subsequent neoplasms (SN) and nonmalignant late effects (NM-LE) in 2-year disease-free adult survivors following hematopoietic cell transplantation (HCT) for a hematologic malignancy. To do so, we conducted a retrospective analysis of 3884 survivors of HCT for hematologic malignancy in the Center of International Blood and Marrow Transplant Research database. We conducted a landmark analysis at the 2-year post-transplantation date, comparing first SN and NM-LE in survivors with and without cGVHD. The cumulative incidence (CuI) of SN and NM-LE were estimated through 10 years post-HCT in both groups, with death or disease relapse as a competing risk. Cox proportional hazards models were used to evaluate the associations of cGVHD and its related characteristics with the development of SN and NM-LE. The estimated 10-year CuI of SN in patients with GVHD (n = 2669) and patients without cGVHD (n = 1215) was 15% (95% confidence interval [CI], 14% to 17%) versus 9% (7.2% to 11%) (P < .001). cGVHD by 2 years post-HCT was independently associated with SN (hazard ratio [HR], 1.94; 95% CI, 1.53 to 2.46; P < .0001) with a standardized incidence ratio of 3.2 (95% CI, 2.9 to 3.5; P < .0001). Increasing severity of cGVHD was associated with an increased risk of SN. The estimated 10-year CuI of first NM-LE in patients with and without cGVHD was 28 (95% CI, 26% to 30%) versus 13% (95% CI, 11% to 15%) (P < .001). cGVHD by 2 years post-HCT was independently associated with NM-LE (HR, 2.23; 95% CI, 1.81 to 2.76; P < .0001). Multivariate analysis of cGVHD-related factors showed that increasing severity of cGVHD, extensive grade, having both mucocutaneous and visceral involvement, and receiving cGVHD treatment for >12 months were associated with the greatest magnitude of risk for NM-LE. cGVHD was closely associated with both SN and NM-LE in adult survivors of HCT for hematologic malignancy. Patients identified as having more severe involvement and both mucocutaneous and visceral organ involvement may warrant enhanced monitoring and screening for SNs and NM-LEs. However, caution is warranted when interpreting these results, as patients with cGVHD may have more vigilant post-transplantation health care and surveillance for late effects.
