Trends in Volumes and Survival After Hematopoietic Cell Transplantation in Racial/Ethnic Minorities.

There has been an increase in volume as well as improvement in overall survival (OS) after hematopoietic cell transplantation (HCT) for hematologic disorders. It is unknown if these changes have impacted racial/ethnic minorities equally. In this observational study from Center for International Blood and Marrow Transplant Research of 79,904 autologous (auto) and 65,662 allogeneic (allo) HCTs, we examined the volume and rates of change of auto HCT and allo HCT over time and trends in OS in 4 racial/ethnic groups: Non-Hispanic Whites (NHWs), Non-Hispanic African Americans (NHAAs), Hispanics across five 2-year cohorts from 2009 to 2018. Rates of change were compared using Poisson model. Adjusted and unadjusted Cox proportional hazards models examined trends in mortality in the 4 racial/ethnic groups over 5 study time periods. The rates of increase in volume were significantly higher for Hispanics and NHAAs vs. NHW for both autoHCT and alloHCT. Adjusted overall mortality after autoHCT was comparable across all racial/ethnic groups. NHAA adults (HR 1.13; 95% CI 1.04-1.22; p=0.004) and pediatric patients (HR 1.62; 95% CI 1.3-2.03; p<0.001 had a higher risk of mortality after alloHCT compared to NHWs. Improvement in OS over time was seen in all 4 groups after both autoHCT and alloHCT.Our study shows the rate of change for the use of autoHCT and alloHCT is higher in NHAAs and Hispanics compared to NHWs. Survival after autoHCT and alloHCT improved over time, however NHAAs have worse OS after alloHCT which has persisted. Continued efforts are needed to mitigate disparities for patients requiring alloHCT.

Vaccination of Adults With Cancer: ASCO Guideline.

PURPOSE: To guide the vaccination of adults with solid tumors or hematologic malignancies. METHODS: A systematic literature review identified systematic reviews, randomized controlled trials (RCTs), and nonrandomized studies on the efficacy and safety of vaccines used by adults with cancer or their household contacts. This review builds on a 2013 guideline by the Infectious Disease Society of America. PubMed and the Cochrane Library were searched from January 1, 2013, to February 16, 2023. ASCO convened an Expert Panel to review the evidence and formulate recommendations. RESULTS: A total of 102 publications were included in the systematic review: 24 systematic reviews, 14 RCTs, and 64 nonrandomized studies. The largest body of evidence addressed COVID-19 vaccines. RECOMMENDATIONS: The goal of vaccination is to limit the severity of infection and prevent infection where feasible. Optimizing vaccination status should be considered a key element in the care of patients with cancer. This approach includes the documentation of vaccination status at the time of the first patient visit; timely provision of recommended vaccines; and appropriate revaccination after hematopoietic stem-cell transplantation, chimeric antigen receptor T-cell therapy, or B-cell-depleting therapy. Active interaction and coordination among healthcare providers, including primary care practitioners, pharmacists, and nursing team members, are needed. Vaccination of household contacts will enhance protection for patients with cancer. Some vaccination and revaccination plans for patients with cancer may be affected by the underlying immune status and the anticancer therapy received. As a result, vaccine strategies may differ from the vaccine recommendations for the general healthy adult population vaccine.Additional information is available at www.asco.org/supportive-care-guidelines.

Multiple Myeloma in Young Patients: A Scoping Review.

Data on the disease course, presenting features, outcomes, and prognosis of younger patients with multiple myeloma (MM) are lacking. Younger patients with MM have historically been considered to have better outcomes primarily based on better tolerance of treatment and lack of medical comorbidities, but the specific age range of this population has not been uniformly defined. Given the lack of consistent data reporting in patients considered to be young MM patients, we performed a scoping review to highlight the research currently available to start drawing conclusions about these patients and highlight unmet areas of need to focus on further investigation. We searched Embase, Cochrane Central Register of Controlled Trials, CINAHL Plus, Web of Science, and the OVID version of MEDLINE including broad terms that embody the concept of young patients with MM. Our final review included 201 studies which were then categorized according to age group, number of patients, outcomes, and comparators to older patients, along with location and database when available. We have chosen to categorize 3 age groupings: <50: young adults with MM (YA MM), 50 to 65: mid-life adults with multiple myeloma (ML MM) and 65+: older adults with multiple myeloma (OA MM). This review demonstrates the heterogeneity that exists in defining and describing young patients with MM, highlights the lack of studies specifically addressing the unique needs of younger patients, and emphasizes areas of future research unique to this population.

Second-Line Chimeric Antigen Receptor T-Cell Therapy in Diffuse Large B-Cell Lymphoma : A Cost-Effectiveness Analysis.

BACKGROUND: First-line treatment of diffuse large B-cell lymphoma (DLBCL) achieves durable remission in approximately 60% of patients. In relapsed or refractory disease, only about 20% achieve durable remission with salvage chemoimmunotherapy and consolidative autologous stem cell transplantation (ASCT). The ZUMA-7 (axicabtagene ciloleucel [axi-cel]) and TRANSFORM (lisocabtagene maraleucel [liso-cel]) trials demonstrated superior event-free survival (and, in ZUMA-7, overall survival) in primary-refractory or early-relapsed (high-risk) DLBCL with chimeric antigen receptor T-cell therapy (CAR-T) compared with salvage chemoimmunotherapy and consolidative ASCT; however, list prices for CAR-T exceed $400 000 per infusion. OBJECTIVE: To determine the cost-effectiveness of second-line CAR-T versus salvage chemoimmunotherapy and consolidative ASCT. DESIGN: State-transition microsimulation model. DATA SOURCES: ZUMA-7, TRANSFORM, other trials, and observational data. TARGET POPULATION: "High-risk" patients with DLBCL. TIME HORIZON: Lifetime. PERSPECTIVE: Health care sector. INTERVENTION: Axi-cel or liso-cel versus ASCT. OUTCOME MEASURES: Incremental cost-effectiveness ratio (ICER) and incremental net monetary benefit (iNMB) in 2022 U.S. dollars per quality-adjusted life-year (QALY) for a willingness-to-pay (WTP) threshold of $200 000 per QALY. RESULTS OF BASE-CASE ANALYSIS: The increase in median overall survival was 4 months for axi-cel and 1 month for liso-cel. For axi-cel, the ICER was $684 225 per QALY and the iNMB was -$107 642. For liso-cel, the ICER was $1 171 909 per QALY and the iNMB was -$102 477. RESULTS OF SENSITIVITY ANALYSIS: To be cost-effective with a WTP of $200 000, the cost of CAR-T would have to be reduced to $321 123 for axi-cel and $313 730 for liso-cel. Implementation in high-risk patients would increase U.S. health care spending by approximately $6.8 billion over a 5-year period. LIMITATION: Differences in preinfusion bridging therapies precluded cross-trial comparisons. CONCLUSION: Neither second-line axi-cel nor liso-cel was cost-effective at a WTP of $200 000 per QALY. Clinical outcomes improved incrementally, but costs of CAR-T must be lowered substantially to enable cost-effectiveness. PRIMARY FUNDING SOURCE: No research-specific funding.

Use of subjective minimizing language at hematology and oncology conferences: A systematic review.

BACKGROUND: Subjective minimizing language in oncology conferences may undermine patient-centered care and hinder comprehensive treatment strategies. Subjective terms like "safe," "tolerable," and "well-tolerated" can vary in interpretation among individuals, making it difficult to compare results across trials and potentially downplaying significant risks and limitations associated with treatments. METHODS: This study evaluates subjective minimizing language in major oncology conferences and its use in adverse event reporting. We conducted a search of three electronic databases, ASCO, ASH, and ESMO, for published abstracts from January 1, 2019, to December 31, 2021. This study included prospective cohort studies or clinical trials in humans that used safety terms like "safe," "well-tolerated," "tolerable," "no new safety signal," or "no new safety concern" in the abstract text. RESULTS: Out of 34,975 reviewed records, 5299 (15.2%) abstracts used subjective minimizing language terms. The analysis included 2797 (52.8%) abstracts meeting the inclusion criteria. The majority of studies were Phase 1 trials (45.5%), followed by Phase 2 (29.6%) and Phase 3 trials (7.4%). Solid tumors accounted for the most common disease category (56.5%), followed by malignant hematology following (37.1%). Subjective minimizing terms like "safe" (69.2%), "well-tolerated" (53.2%), "tolerable" (25.6%), and "no new safety signal/concerns" (10%) were used frequently. Of the abstracts using subjective minimizing language (n = 2797), 81.9% reported data on any grade adverse events (AEs). Grade I/II AEs were reported in 62.6% of abstracts, Grade III/IV AEs in 78%, and Grade V AEs (death related to AEs) in 8.8%. Discontinuation due to AEs occurred in 11.4% (SD 9.5%) of studies using subjective minimizing language terms. CONCLUSIONS: Frequent use of subjective minimizing language in major oncology conferences' abstracts may obscure interpretation of study results and the safety of novel treatments. Researchers and clinicians should provide precise and standardized information to avoid overstatement of benefits and understand the true impact of interventions on patients' safety and well-being.

Characteristics of post hoc subgroup analyses of oncology clinical trials: a systematic review.

BACKGROUND: Subgroup analyses in clinical trials assess intervention effects on specific patient subgroups, ensuring generalizability. However, they are usually only able to generate hypotheses rather than definitive conclusions. This study examined the prevalence and characteristics of post hoc subgroup analysis in oncology. METHODS: We systematically reviewed published subgroup analyses from 2000 to 2022. We included articles presenting secondary, post hoc, or subgroup analyses of interventional clinical trials in oncology, cancer survivorship, or cancer screening, published separately from the original clinical trial publication. We collected cancer type, year of publication, where and how subgroup analyses were reported, and funding. RESULTS: Out of 16 487 screened publications, 1612 studies were included, primarily subgroup analyses of treatment trials for solid tumors (82%). Medical writers contributed to 31% of articles, and 58% of articles reported conflicts of interest. Subgroup analyses increased significantly over time, with 695 published between 2019 and 2022, compared to 384 from 2000 to 2014. Gastrointestinal tumors (25%) and lymphoid lineage tumors (39%) were the most frequently studied solid and hematological malignancies, respectively. Industry funding and reporting of conflicts of interest increased over time. Subgroup analyses often neglected to indicate their secondary nature in the title. Most authors were from high-income countries, most commonly North America (45%). CONCLUSIONS: This study demonstrates the rapidly growing use of post hoc subgroup analysis of oncology clinical trials, revealing that the majority are supported by pharmaceutical companies, and they frequently fail to indicate their secondary nature in the title. Given the known methodological limitations of subgroup analyses, caution is recommended among authors, readers, and reviewers when conducting and interpreting these studies.

Assessing Medicaid Coverage for Hematopoietic Cell Transplantation and Chimeric Antigen Receptor T Cell Therapy: A Project from the American Society for Transplantation and Cellular Therapy and the National Marrow Donor Program ACCESS Initiative.

The American Society for Transplantation and Cellular Therapy (ASTCT) and the National Marrow Donor Program (NMDP) formed the ACCESS Initiative to address and reduce barriers to hematopoietic cell transplantation (HCT) and cellular therapy (CT) to ensure equal access and outcomes for all patients in need. The 3 committees, addressing awareness, poverty, and racial and ethnic inequity, defined pilot projects focusing on addressing relevant barriers to HCT/CT. Because many socioeconomically disadvantaged HCT/CT recipients receive care through state Medicaid programs, the Poverty Committee conducted a Medicaid scan of all 50 US states with the following objectives: to define beneficiary coverage for allogeneic and autologous HCT and chimeric antigen receptor (CAR) T cell therapy; to define support for travel, temporary lodging, and meals for both beneficiaries and caregivers; and to determine search and cell acquisition payment procedures. Here we summarize the results of the Medicaid scan and highlight significant variations and gaps in coverage for HCT/CT recipients. We also provide an initial roadmap for addressing gaps in Medicaid support for HCT and CAR-T therapy recipients.

Racial and Socioeconomic Disparities in Long-Term Outcomes in ≥1 Year Allogeneic Hematopoietic Cell Transplantation Survivors: A CIBMTR Analysis.

Racial/ethnic minorities have demonstrated worse survival after allogeneic hematopoietic cell transplantation (HCT) compared to whites. Whether the racial disparity in HCT outcomes persists in long-term survivors and possibly may be even exacerbated in this population, which frequently transitions back from the transplant center to their local healthcare providers, is unknown. In the current study, we compared long-term outcomes among 1-year allogeneic HCT survivors by race/ethnicity and socioeconomic status (SES). The Center for International Blood and Marrow Transplant Research database was used to identify 5473 patients with acute myeloid leukemia, acute lymphocytic leukemia, chronic myeloid leukemia, or myelodysplastic syndromes who underwent their first allogeneic HCT between 2007 and 2017 and were alive and in remission for at least 1 year after transplantation. The study was restricted to patients who underwent HCT in the United States. SES was defined using patient neighborhood poverty level estimated from the recipient's ZIP code of residence; a ZIP code with ≥20% of persons below the federal poverty level was considered a high poverty area. The primary outcome was to evaluate the associations of race/ethnicity and neighborhood poverty level with overall survival (OS), relapse, and nonrelapse mortality (NRM). Cox regression models were used to determine associations of ethnicity/race and SES with OS, relapse, and NRM. Standardized mortality ratios were calculated to compare mortality rates of the study patients and their general population peers matched on race/ethnicity, age, and sex. The study cohort was predominately non-Hispanic white (n = 4385) and also included non-Hispanic black (n = 338), Hispanic (n = 516), and Asian (n = 234) patients. Overall, 729 patients (13%) resided in high-poverty areas. Significantly larger proportions of non-Hispanic black (37%) and Hispanic (26%) patients lived in high-poverty areas compared to non-Hispanic whites (10%) and Asians (10%) (P < .01). Multivariable analysis revealed no significant associations between OS, PFS, relapse, or NRM and race/ethnicity or poverty level when adjusted for patient-, disease- and transplantation-related covariates. Our retrospective cohort registry study shows that among adult allogeneic HCT recipients who survived at least 1 year in remission, there were no associations between race/ethnicity, neighborhood poverty level, and long-term outcomes.

High Cost of Chimeric Antigen Receptor T-Cells: Challenges and Solutions.

Chimeric antigen receptor (CAR) T-cells are a cellular immunotherapy with remarkable efficacy in treating multiple hematologic malignancies but they are associated with extremely high prices that are, for many countries, prohibitively expensive. As their use increases both for hematologic malignancies and other indications, and large numbers of new cellular therapies are developed, novel approaches will be needed both to reduce the cost of therapy, and to pay for them. We review the many factors that lead to the high cost of CAR T-cells and offer proposals for reform.

Long-term health outcomes of allogeneic hematopoietic stem cell transplantation.

Background: Fifty years of hematopoietic cell transplantation (HCT) has ushered in an exciting era of cellular therapy and has led to enormous progress in improving the outcomes of patients with both malignant and non-malignant hematologic disease. As the survival of transplanted patients has increased, so has the recognition of long-term complications related to this therapy. Purpose: The goal of this review is to highlight some of the most common long-term complications of HCT. Data sources: To this end, we have conducted a review of the published literature on the long-term complications of HCT encompassing the past 50 years. Study selection: We have endeavored to include long-term complications reported in research articles, case series and case reports, reviews, and abstracts. We have focused primarily on adult allogeneic HCT, but have included some data from studies of pediatric allogeneic HCT as well. We have also prioritized the literature published in the last 15 years. Data extraction: Key data supporting the onset and prevalence of the most common long-term complications was extracted. Limitations: While the list of long-term complications extracted and reported was comprehensive, it was not exhaustive. Conclusions: We have endeavored to highlight some of the most common long-term complications of HCT, the recognition and management of which constitutes an important part of HCT survivorship care.

Clinical Features of Acute Kidney Injury in the Early Post-Transplantation Period Following Reduced-Intensity Conditioning Allogeneic Hematopoietic Stem Cell Transplantation.

Allogeneic hematopoietic stem cell transplantation (HCT) is a potentially curative therapy for patients with hematologic malignancies but is associated with acute kidney injury (AKI). To date, few studies have examined risk factors for AKI at engraftment, or the relationship between AKI and clinical outcomes. This study examined the incidence and risk factors for periengraftment AKI, as well as the association between AKI and overall survival (OS) and nonrelapse mortality (NRM). We conducted a retrospective analysis of adult patients undergoing reduced-intensity conditioning (RIC) allogeneic HCT at the Dana-Farber Cancer Institute between 2012 and 2019. Periengraftment (day 0 to day 30) AKI incidence and severity were defined using modified KDIGO (Kidney Disease: Improving Global Outcomes) criteria. Factors associated with periengraftment AKI risk were examined using Cox regression analysis. The impact of periengraftment AKI on OS and NRM (defined as death without recurrent disease after HCT), was evaluated using Cox regression and the Fine and Gray competing risks model, respectively. Kidney recovery, defined as a return of serum creatinine (SCr) to within 25% of baseline or liberation from kidney replacement therapy (KRT), was examined at day 90 post-HCT. Periengraftment AKI occurred in 330 of 987 patients (33.4%) at a median of 13 days (interquartile range, 4 to 30 days) post-transplantation. Factors associated with a higher multivariable-adjusted risk of AKI were supratherapeutic rapamycin (hazard ratio [HR], 1.56; 95% confidence interval [CI], 1.20 to 2.03; P < .001), fludarabine/melphalan conditioning (HR, 1.35, 95% CI, 1.01 to 1.81; P = .05, compared to fludarabine/busulfan and fludarabine, cyclophosphamide, and total body irradiation), HCT Comorbidity Index ≥4 (HR, 1.43; 95% CI, 1.14 to 1.79; P = .002), albumin <3.4 g/dL (HR, 2.04; 95% CI, 1.33 to 3.12; P = .001), hemoglobin ≤12 (HR, 1.96; 95% CI, 1.38 to 2.78; P < .001), supratherapeutic tacrolimus (HR, 1.45; 95% CI, 1.07 to 1.95; P = .02), and baseline SCr >1.1 mg/dL (HR, 1.87; 95% CI, 1.48 to 2.35; P < .001). Periengraftment AKI was associated with worse OS (HR, 1.40; 95% CI, 1.16 to 1.71; P < .001) and NRM (subdistribution HR, 2.10; 95% CI, 1.52 to 2.89; P < .001). Kidney recovery occurred in 18%, 15%, and 30% of patients with stage 1, stage 2, and stage 3 AKI without KRT, respectively, and 4 of 16 patients (25%) were liberated from KRT. Periengraftment AKI is common among RIC allogeneic HCT recipients. We identified several important risk factors for periengraftment AKI. Its association with worse OS and NRM underscores the importance of timely recognition and management.

Demographics, Motivations, and Experiences of Participants in Transplantation or Cellular Therapy Fellowships.

Recent American Society for Transplantation and Cellular Therapy guidelines have sought to establish clinical and research expectations for participants in blood and marrow transplantation (BMT) and cellular therapy (CT) fellowships. However, little is known about participants in BMT/CT fellowships and the value they find from this additional training. We wanted to characterize the demographics, motivations, and experiences of recent participants in BMT/CT fellowships. We developed a 27-item online survey addressing backgrounds, application processes, training experiences, and perceived benefits among physicians who had started a clinical U.S.-based BMT/CT fellowship between 2012 to 2021. Anonymous responses were solicited through program director outreach, society website postings, targeted emails, and social media. Of 105 respondents (44% pediatric trainees), 4% were URMs and 39% were non-U.S. IMGs. The most important motivations for applying were comfort with allogeneic BMT, improved career prospects, and opportunities for research and publication. Almost all respondents (92%) attended donor selection meetings, whereas smaller proportions visited cell processing facilities (65%), HLA laboratories (57%), or good manufacturing practice facilities (22%). Most respondents reported ≥1 publication (26% reported 4+) based on research or experiences during their fellowship. Respondents reported improved post-fellowship comfort with all queried BMT/CT-related competencies. Seventy percent of respondents stated that they would recommend their fellowship highly to others; this corresponded to a Net Promoter Score of +65%, consistent with a strongly positive experience. Most respondents reported currently being in clinical practice (89% at academic centers), with a median of 70% of time currently spent caring for BMT/CT recipients. Although limited by recruitment methods and recall bias, our study demonstrated that BMT/CT fellowships are effective at increasing comfort with BMT/CT management and that most participants would highly recommend this BMT/CT training to others. Nevertheless, our study identified substantial heterogeneity in clinical responsibilities and BMT/CT-related laboratory exposure. The high representation of non-U.S. IMGs underscores the distinct role of BMT/CT fellowships for this group, whereas improved URM recruitment remains an important future direction for the field. Whether advanced fellowships will ever become required for the future BMT/CT workforce, analogous to the additional training required for solid organ transplantation in other medical and pediatric subspecialties, remains uncertain.

Analysis of repeated roles in editorial boards at oncology focused journals.

AIM OF THE STUDY: Our objective was to investigate current landscape of editorial board members at oncology journals with a focus on characteristics of editorial board members who serve on editorial boards at multiple journals concurrently. METHODS: We conducted a cross-sectional study describing characteristics of editorial board members at oncology journals with an impact factor (IF) of ≥ 10 in the 2020 Journal Citation Reports. RESULTS: A total of 73 journals in the period of 2016-2020 were analyzed. A total of 5833 editorial roles were included in our final analysis of which 3979 (68%) roles were carried by men and 3572 (61%) were members located in the US. Repeated roles occurred in 1101 (19%; range: 2-6 roles) of total included editorial roles and were distributed in 488 distinct editorial members. Most editorial board members with repeated roles carried either 2 roles (80%) or 3 roles (17%); however, 18 (3%) editorial board members carried ≥ 4 roles at different journals. A total of 23% of editors-in-chief carried another editorial role at a different journal. Only 1% of all editorial roles were carried by individuals affiliated with universities located in low- or middle-income countries. CONCLUSION: One-fifth of the editorial board positions were held by members who served on more than one editorial board, including members serving as editors-in-chief. Editors with repeated roles may be at higher risk for influence from competing interests and diminished quality of work, may contribute to publication delays, and may limit editorial opportunities for other qualified scientists. POLICY STATEMENT: A considerable number of editorial team members had multiple roles across various cancer-focused journals, including members serving as editors in chief. Such repeated roles limit appropriate representation and hinders diversity in academia. Regulations to prevent repeated editorial roles are needed.

The Impact of Pre-Apheresis Health Related Quality of Life on Peripheral Blood Progenitor Cell Yield and Donor's Health and Outcome: Secondary Analysis of Patient-Reported Outcome Data from the RDSafe and BMT CTN 0201 Clinical Trials.

There is a lack of evidence about how health-related quality of life (HRQoL), including psychosocial factors, might affect donation-related experiences and clinical markers in the context of hematopoietic stem cell donation. The broader literature suggests that psychological factors, including anxiety and depression, are associated with higher levels of inflammatory burden leading to poorer postprocedural outcomes including longer hospital stays and increased pain perception. In this study, we aimed to evaluate whether predonation HRQoL markers predict toxicity profile and stem cell yield after peripheral blood stem cell (PBSC) donation in healthy donors. The study population comprised adult granulocyte colony-stimulating factor mobilized PBSC-related donors (RD) (n = 157) and unrelated donors (URD) (n = 179) enrolled in the related donor safety study (RDSafe) and Blood and Marrow Transplant Clinical Trials Network (BMT CTN) 0201 clinical trials. Pre-donation HRQoL was assessed using the Short-Form-12 (SF-12) in RDSafe and SF-8 questionnaire in BMT CTN 0201 (higher score is better). The aims of this study were to (a) determine the impact of pre-donation HRQoL on peri-collection pain and acute toxicities experienced and (b) to investigate the pre-procedural HRQoL indicators on stem cells yield. URDs were younger than RDs (median age 35 versus 63). A higher proportion of RDs were female (50% versus 40%) and obese (41% versus 35%). A higher proportion of RD PBSC donations required 2 days or more of apheresis (44% versus 21%). More RD collections were lower volume procedures (<18L, 16% versus 28%), and required a central line (28% versus 11%). RDs were more likely to report pre-donation grade 1-2 pain (27% versus 8%) and other toxicities (16% versus 6%). Among RDs, a lower pre-donation physical component summary (PCS) score was associated with significantly more grade 2-4 pain at 1 month (P = .004) and at 1-year after donation (P = .0099) in univariable analyses. In multivariable analysis, pre-donation PCS remained significantly associated with grade 2-4 pain 1 month after donation (P = .0098). More specifically, RDs with predonation PCS scores in the highest quartile were less likely to report pain compared with donors with PCS scores in the lowest quartile (odds ratio 0.1; 95% confidence interval 0.01-0.83; P = .005). There was also a trend toward higher grade 2-4 pain at 1-year post-donation among RDs with lower predonation PCS score (P = .018). Among URDs, neither PCS nor mental component summary (MCS) scores were associated with pain or toxicities at any time point after donation based on the univariable analysis. Because of low rates of postdonation grade 2-4 pain and toxicities, multivariable analysis was not performed in the URD setting. Moreover, there was no correlation between preapheresis HRQoL score (PCS or MCS) and PBSC collection yield in either the RD or URD setting. Our study demonstrates that pre-donation HRQoL scores are significantly associated with the toxicity profile after PBSC donation in the RD setting, with adult RDs with lower predonation physical HRQoL experiencing higher levels of pain at 1 month and persisting up to 12 months after a PBSC collection procedure. There were no such associations found in URD. Our findings can help clinicians identify donors at higher risk of pain with donation, and lead to personalized information and interventions for specific donors. Lack of correlation between predonation HRQoL and stem cell yield may be due to a small sample size and warrants further evaluation.

Peer support in patients with hematologic malignancies undergoing hematopoietic stem cell transplantation (HSCT): a qualitative study.

Peer support, a distinctive form of social support in which patients share emotional, social, and practical help based on their own lived experience of illness and treatment, positively impacts patient-reported outcomes in cancer populations. However, data on peer support experiences among hematopoietic stem cell transplant (HSCT) recipients are limited. We conducted semi-structured qualitative interviews among 12 allogeneic HSCT recipients who were ≤6 months post transplant without any complications and 13 allogeneic HSCT recipients >6 months post transplant and living with chronic graft-versus-host disease. Interviews explored patients' experiences with peer support and their preferences for a peer support intervention tailored to the needs of HSCT recipients. While the majority (70%) of participants reported no formal experience with peer support, most (83%) articulated themes of potential benefits of peer support (e.g., managing expectations and uncertainty that accompany HSCT). Most participants (60%) reported a preference for a peer support intervention prior to the HSCT hospitalization. Despite the limited data on peer support interventions among HSCT recipients and lack of formal peer support experience in most of our cohort, our study shows that HSCT recipients clearly acknowledge the potential benefits of a peer support intervention, and they prefer that it start prior to transplantation.

Time is Blood: The Impact of Diagnostic Delays on Acquired Hemophilia A.

Background and objective Acquired hemophilia A (AHA) is an uncommon autoimmune bleeding disorder caused by the formation of neutralizing antibodies against endogenous factor VIII (FVIII). Delays between the onset of symptoms and the correct diagnosis of the condition lead to poor outcomes and a higher mortality rate. In this study, we aimed to analyze the impact of delays in diagnosis on AHA patients. Methods We conducted a retrospective study at a single hospital system between March 1, 2010, and January 17, 2017, which included six patients meeting the criteria for AHA diagnosis. Results Initial analysis revealed a median age of 79.5 years and a median time to diagnosis from the onset of bleeding of 14 days. Among the six patients, three had cancer (bladder, renal, and prostate) and three had unknown etiologies. One of the patients died prior to the initiation of a bypassing agent. The remaining five patients received recombinant FVIIa (NovoSeven®, Novo Nordisk, Bagsværd, Denmark), and two of those five required a second-line bypassing agent, recombinant porcine sequence FVIII (Obizur®, Takeda Pharmaceutical, Tokyo, Japan) for refractory bleeding. All five patients achieved hemostasis; however, three died within a year, and none of the patients survived for five years. Four of these five patients died directly from bleeding complications. Conclusions Based on our study findings and review of the literature, we propose an algorithm to potentially aid in the early diagnosis and treatment of AHA in emergency and non-specialized settings.

Administration of Immune Checkpoint Inhibitors Near the End of Life.

PURPOSE: Recent literature suggests an increasing use of systemic treatment in patients with advanced cancer near the end of life (EOL), partially driven by the increasing adoption of immune checkpoint inhibitors (ICIs). While studies have identified this trend, additional variables associated with ICI use at EOL are limited. Our aim was to characterize a population of patients who received a dose of ICI in the last 30 days of life. METHODS: We performed a manual retrospective chart review of patients ≥ 18 years who died within 30 days of receiving a dose of ICI. Metrics such as Eastern Cooperative Oncology Group performance status (ECOG PS), number of ICI doses, need for hospitalization, and numerous other variables were evaluated. RESULTS: Over a 4-year time period, 97 patients received an ICI at EOL. For 40% of patients, the ICI given in the 30 days before death was their only dose. Over 50% of patients had an ECOG PS of ≥ 2, including 17% of patients with an ECOG PS of 3. Over 60% were hospitalized, 65% visited the emergency department, 20% required intensive care unit admission, and 25% died in the hospital. CONCLUSION: Our study contributes to the ongoing literature regarding the risks and benefits of ICI use in patients with advanced cancer near the EOL. While accurate predictions regarding the EOL are challenging, oncologists may routinely use clinical factors such as ECOG PS along with patient preferences to guide recommendations and shared decision making. Ultimately, further follow-up studies to better characterize and prognosticate this population of patients are needed.
