Temporal trends in critical care utilization and outcomes in allogeneic hematopoietic stem cell transplant recipients.

Historically, the prognosis of allogeneic hematopoietic stem cell transplant (allo-HCT) recipients who require intensive care unit (ICU) admission has been poor. We aimed to describe the epidemiological trends of ICU utilization and outcomes in allo-HCT patients. We conducted a retrospective cohort study including adults (≥ 18) undergoing allo-HCT between 01/01/2005 and 31/12/2020 at Mayo Clinic, Rochester. Temporal trends in outcomes were assessed by robust linear regression modelling. Risk factors for hospital mortality were chosen a priori and assessed with multivariable logistic regression modelling. Of 1,249 subjects, there were 486 ICU admissions among 287 individuals. Although older patients underwent allo-HCT (1.64 [95% CI: 1.11 to 2.45] years per year; P = 0.025), there was no change in ICU utilization over time (P = 0.91). The ICU and hospital mortality rates were 19.2% (55/287) and 28.2% (81/287), respectively. There was a decline in ICU mortality (-0.38% [95% CI: -0.70 to -0.06%] per year; P = 0.035). The 1-year post-HCT mortality for those requiring ICU admission was 56.1% (161/287), with no significant difference over time, versus 15.8% (141/891, 71 missing) among those who did not. The frequency and duration of invasive mechanical ventilation (IMV) declined. In multivariable analyses, higher serum lactate, higher sequential organ failure assessment (SOFA) scores, acute respiratory distress (ARDS), and need for IMV were associated with greater odds of hospital mortality. Over time, rates of ICU utilization have remained stable, despite increasing patient age. Several trends suggest improvement in outcomes, notably lower ICU mortality and frequency of IMV. However, long-term survival remains unchanged. Further work is needed to improve long-term outcomes in this population.

Preparing Hematology/Oncology Fellows for Success: Implementing an Annual Career Development and Research Retreat.

Multiple factors, including job satisfaction, personality traits, and training experiences, influence the career trajectory of hematology/oncology fellows. In an effort to expose hematology/oncology fellows to (1) the various careers in oncology, (2) a diverse group of speakers for future mentorship, and (3) research opportunities, and grant writing experience, we established an annual career development and research retreat. During the retreat, we engaged speakers who covered a range of career trajectories, including academic, private practice, industry, government, and administrative paths. We introduced clinicians and researchers with a track record of providing top-notch mentorship to fellows with aligning interests and detailed research opportunities and grant writing. The sessions were led by senior fellows, and we adopted an in-person and virtual hybrid model to allow speakers from various institutions to participate. Feedback from participants, as gathered through surveys, indicated positive responses: all respondents reported that this retreat was "extremely" or "very helpful," and a majority expressed their intent to pursue academic careers. The curriculum and structure of this retreat may help to inform the development of fellowship career development and research retreats at other institutions.

Day 100 Natural Killer Cell/CD14+HLA-DRDIM ratio and survival in lymphoma post-autologous peripheral blood hematopoietic stem cell transplantation.

INTRODUCTION: The infusion of autograft Natural Killer Cells (NKC)/CD14+ HLA-DRDIM ratio is a predictor of survival in lymphoma patients undergoing autologous peripheral blood hematopoietic stem cell transplantation (APBHSCT). This study evaluated if the Day 100 NKC/CD14+ HLA-DRDIM ratio still functions as a prognostic immune-biomarker. METHODS: This was a retrospective, single-institution, cohort analysis including 107 patients in this study that had clinical assessment at Day 100 post-APBHSCT from our prior phase III trial. We evaluated the prognostic ability of the Day 100 NKC/CD14+ HLA-DRDIM ratio to predict overall survival (OS) and progression-free survival (PFS) using Cox regression model for outcome analysis and survival by Kaplan-Meier method. RESULTS: The median follow-up from day 100 was 94.7 months (range 4.83-158.1 months) for the entire cohort. Patients with a Day 100 NKC/CD14+ HLA-DRDIM ratio ≥1.67 experienced better OS and PFS versus those with a Day 100 NKC/CD14+ HLA-DRDIM ratio <1.67: median OS was not reached versus 49.7 months, the 5-year OS rates were 91% (95% CI, 81%-96%) versus 40% (95% CI, 27%-55%), p < .0001, respectively; and median PFS was not reached versus 23.5 months, the 5-year PFS rates were 66% (95% CI, 55%-81%) versus 21% (95% CI, 15%-40%), p < .0001, respectively. Day 100 NKC/CD14+ HLA-DRDIM ratio was an independent predictor for OS and PFS in the multivariate analysis. CONCLUSIONS: Day 100 NKC/CD14+ HLA-DRDIM ratio is a prognostic immune-biomarker in lymphoma patients post- APBHSCT.

Analysis of Medicare Expenditure for Discarded Infused Cancer Therapeutics From 2017-2020.

OBJECTIVE: To explore patterns in Medicare reimbursement for wasted oncologic and hematologic infusion drugs from 2017 to 2020 and estimate the savings that implementation of the Infrastructure Investment and Jobs Act (IIJA) would have had. METHODS: Using the publicly available Medicare Part B Discarded Drug Units database, we analyzed reimbursement data for discarded antineoplastic and hematology therapies from 2017 to 2020. RESULTS: Medicare Part B utilization data was extracted for 77 therapies. From 2017 to 2020, the median annual dollar value of discarded therapies was $590 million. Every year, bortezomib, azacitidine, cabazitaxel, and decitabine were among the most wasted products, an average 24% waste. The IIJA policy would have impacted a median of 20 oncology agents and resulted in median annual refund of $172 million. Had the top five most discarded therapies been redistributed, they could have treated 18,289 patients. The five most wasted drugs were all dosed by weight and distributed in single-use vials. CONCLUSION: The IIJA could potentially significantly reduce waste or encourage redistribution to treat thousands of additional patients. We propose that a fusion of fixed and weight-based dosing may help reduce wasteful medication administration by offering doses that better accommodate most patients. We anticipate that manufacturers will adapt to the IIJA perhaps by adjusting fixed doses or simply increasing drug prices. If price changes from dose delivery adjustment occur, rebates offered to pharmacy benefit managers and insurers will likely follow suit and may alter formulary positioning.

Relationships Among Health Insurance Literacy, Financial Toxicity, and Sociodemographic Factors in Patients With Cancer.

PURPOSE: The objective of the study was to describe the prevalence of health insurance literacy (HIL) and investigate how patient-reported outcome measures assessing HIL are related to financial toxicity in patients with cancer. METHODS: We assessed HIL and financial toxicity in 404 patients enrolled between December 2019 and January 2021 at two medical centers in the United States. We conducted exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) to explore and test the relationships among the factors and items. We fit structural equation models (SEMs) to find the relationships among the factors and sociodemographic/clinical characteristics. RESULTS: The EFA revealed items loaded on four factors: knowledge about health insurance, confidence related to HIL (HIL confidence), information-seeking behavior related to health insurance, and financial toxicity. The four-factor CFA model had good fit statistics (comparative fit index, 0.960; Tucker-Lewis index, 0.958; root mean square error of approximation, 0.046; and standardized root mean square residual, 0.086). In SEM, income, education level, and race positively predicted knowledge about health insurance. Knowledge about health insurance and number of total lines of cancer treatment was positively associated with HIL confidence. Higher income, older age, and HIL confidence were associated with less financial toxicity. Higher levels of financial toxicity, HIL confidence, and knowledge were associated with greater information-seeking behavior. CONCLUSION: Our findings showed how different aspects of HIL are related to financial toxicity even after adjustment for sociodemographic and clinical characteristics. Future studies should investigate the longitudinal relationships among these factors to help develop interventions to mitigate financial toxicity.

Response to COVID-19 Vaccination Post-CAR T Therapy in Patients With Non-Hodgkin Lymphoma and Multiple Myeloma.

COVID-19 adversely affects individuals with cancer. Several studies have found that seroconversion rates among patients with hematologic malignancies are suboptimal when compared to patients without cancer. Patients with non-Hodgkin lymphoma (NHL) and multiple myeloma (MM) are immunocompromised due to impaired humoral and cellular immunity in addition to prescribed immunosuppressive therapy. Chimeric antigen receptor T-cell (CAR T) therapy is now widely used for NHL and MM, but little is known about seroconversion rates after COVID-19 vaccination among these populations. We evaluated SARS-CoV-2 spike-binding IgG antibody levels following COVID-19 vaccination among NHL and MM CAR T therapy recipients. Out of 104 CAR T infusions, 19 patients developed known COVID-19 infection post-CAR T. We tested 17 patients that received CAR T for antibody spike titers post COVID-19 vaccination, only 29 % (n = 5) were able to mount a clinically relevant antibody response (>250 IU/mL).

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.

Allogeneic Hematopoietic Stem Cell Transplantation in the Outpatient Setting: The Mayo Clinic Experience.

Hematopoietic stem cell transplantations (HSCT) are intensive and potentially curative modalities available for a variety of hematological diseases. Although alloHSCTs are typically performed in an inpatient setting, there has been increasing interest in moving them to the outpatient setting. AlloHSCTs are associated with a median length of hospital stay of 30 days. AlloHSCTs in the inpatient setting may increase patient exposure to nosocomial infections, drug-resistant organisms, rapid deconditioning with time spent in hospital beds, and loss of muscle mass. In this study, we aim to share outcomes of 856 consecutive alloHSCTs done in our institute over the past 2 decades. This is a single-center retrospective chart review encompassing 856 patients who underwent outpatient alloHSCTs between 2000 and 2017. Reduced-intensity conditioning, stem cell infusion, and much of the immediate follow-up in the early alloHSCT period was performed on an outpatient basis with daily evaluation, laboratory assessment, and intervention as needed. Rate of non-routine hospital admission was our primary outcome of interest. We also looked at various secondary outcomes, including causes of admission, median length of stay, and in-hospital mortality rate. Data analysis was performed using STATA statistical software Version 15. Descriptive statistics were used to summarize baseline demographic data and outcomes. Logistic regression modeling was used to identify predictors of hospital admission. We observed that about one third of our cohort never required admission to the hospital throughout the first 100 days after HSCT. Among those admitted, 6.6% experienced a direct admission to the intensive care unit, and the overall in hospital mortality was low at 5%. Furthermore, the median length of stay was noted to be decreased at 6 days compared to a median reported 30 days in existing literature. Overall, we observed favorable safety profile and outcomes with outpatient management of HSCTs.

Financial hardship in breast cancer survivors: a prospective analysis of change in financial concerns over time.

PURPOSE: Medical financial hardship, encompassing material, behavioral, and psychologic domains, has been shown to impair quality of life during and after cancer therapy. We sought to evaluate the change in financial concerns in breast cancer survivors over time and identify those at risk of worsening financial concerns. METHODS: In Mayo Clinic Breast Disease Registry (MCBDR), a prospective cohort of consenting patients seen at Mayo Clinic Rochester within 1 year of their initial breast cancer diagnosis, consenting participants were asked to complete baseline and annual follow-up surveys that included an item on which respondents were asked to report their financial concerns on a linear analogue scale from 0 ("none") to 10 ("constant concerns"). We compared patient-reported financial concern at baseline to that on each patient's most recent survey, with worsening concerns defined as a 1+-point increase. Logistic regression analysis evaluated for possible predictors of worsening financial concerns. RESULTS: One-thousand nine-hundred fifty-seven participants responded to financial concern questions on the baseline and at least one follow-up survey between 2015 and 2020. Three-hundred fifty-seven (18.2%) reported worsening financial concerns. Only baseline financial situation of "enough to pay the bills, but little spare money to buy extra or special things," was associated with a greater likelihood of worsening financial concerns. CONCLUSIONS: More than one in seven breast cancer survivors develop worsening financial concerns within 5 years of diagnosis, and those with less financial security at baseline appear to be most vulnerable. IMPLICATION FOR CANCER SURVIVORS: Financial concerns may worsen over time for breast cancer survivors, and therefore, oncology providers must continue to assess the financial well-being of survivors over time.

Time to first treatment is an independent prognostic factor for Multiple Myeloma (MM).

INTRODUCTION: Multiple myeloma (MM) is an incurable plasma cell neoplasm. In this study, we aimed to analyze the impact of time to initiation of systemic therapy for MM on overall survival (OS). METHODS: We identified cases diagnosed with MM from the National Cancer Database from 2004 to 2013. RESULTS: A total of 38,178 MM patients were included in the analysis. The median time to systemic therapy in our cohort was 17 days (range 0-120). The median OS for patients who initiated therapy > 30-days after diagnosis was longer than those who received it ≤ 7 days (46 vs. 27-month, p < 0.001). On multivariable analysis, patients who received treatment ≤ 7 days from diagnosis had worse mortality compared with those receiving treatment > 30 days (HR 1.5; 95% CI 1.4-1.6). CONCLUSIONS: In our study, time to initiation of systemic therapy was an independent prognostic factor in MM. Similar to other lymphoid malignancies, this metric may be a surrogate for high-risk disease in MM, and future trials may need to investigate time-to-treatment as a factor to allow enrollment of potentially sick patients.

Frontline polatuzumab vedotin for diffuse large B-cell lymphoma: A survey of clinician impressions.

In the POLARIX trial, pola-R-CHP demonstrated improved progression-free survival (PFS) compared to R-CHOP in untreated intermediate- to high-risk DLBCL. We surveyed practicing clinicians regarding their interpretation of POLARIX, including impressions of efficacy, safety, and cost. Of 174 respondents, most from academic centers (82%) in the United States (57%), 70% stated they would not replace R-CHOP with pola-R-CHP due to insufficient PFS difference, lack of overall survival benefit, and excessive cost. Respondents not recommending pola-R-CHP expressed concerns about financial implications for both society and patients. We observed considerable heterogeneity in both study interpretation and plans for real-world implementation of pola-R-CHP.

The forgotten survivor: A comprehensive review on Non-Hodgkin lymphoma survivorship.

The number of non-Hodgkin lymphoma (NHL) survivors is increasing. With the advancement of NHL therapies, it is crucial to focus on the challenges these survivors may face. Three main categories are to be considered in NHL survivorship, including quality of life and uncertainty about the future, possible physical health complications (including cardiovascular disease, infertility, and subsequent neoplasms), and the impact of novel NHL treatments and their potential complications. The latter includes CAR T-cell therapy, monoclonal antibodies, checkpoint inhibitors, and hematopoietic stem cell transplantation. In this report, we aim to shed the light on these aspects and to discuss survivorship care plan for NHL.

Association of Health Insurance Literacy With Financial Hardship in Patients With Cancer.

Importance: Patient-reported financial hardship is an increasing challenge in cancer care delivery. Health insurance literacy and its association with financial hardship in patients with cancer, especially after controlling for financial literacy, have not been well examined. Objective: To examine the prevalence of and factors in the association between health insurance literacy and financial literacy as well as the overall and individual domains of financial hardship and their association with health insurance literacy, both independently and when adjusted for financial literacy, in patients with cancer. Design, Setting, and Participants: This cross-sectional survey study recruited and enrolled patients from 2 separate ambulatory infusion centers at Mayo Clinic Arizona in Phoenix, Arizona, and the University of Mississippi Medical Center in Jackson, Mississippi. Adult patients aged 18 years or older were enrolled from December 2019 to February 2020 and from August to October 2020 at Mayo Clinic Arizona (n = 299) and from September 2020 through January 2021 at the University of Mississippi Medical Center (n = 105). Survey respondents received a $5 gift card. Exposures: Surveys included questions about sociodemographic characteristics, health insurance literacy and financial literacy, financial knowledge, and financial hardship and its domains (material hardship, psychological hardship, and behavioral hardship). Main Outcomes and Measures: Financial hardship was assessed using the COST-FACIT (Comprehensive Score for Financial Toxicity-Functional Assessment of Chronic Illness Therapy) measure and National Health Interview Survey questions to capture information about the domains of financial hardship. The Health Insurance Literacy Measure is a validated 21-item measure of a consumer's ability to select and use health insurance. Five questions from the National Financial Capability Study assessed financial literacy. Results: A total of 404 participants were enrolled in the study. Median (IQR) age of the respondents was 63 (54-71) years, and 219 were women (54%), 307 were non-Hispanic White individuals (76%), 153 (38%) had private insurance, and 289 (72%) had solid tumors. Overall financial hardship (denoted by median COST-FACIT score <27 points) was reported by 49% (95% CI, 44%-53%) of the cohort. Prevalence of financial hardship was higher using the National Health Interview Survey questions, with 68% (95% CI, 63%-72%) of respondents reporting at least 1 hardship domain (n = 276). Sixty-six percent (95% CI, 60%-69%) of respondents (n = 265) had a high level of financial literacy. The mean (SD) Health Insurance Literacy Measure score was 64.9 (13.3) points. In multivariable analyses, each 10-point increase in the Health Insurance Literacy Measure score was associated with lower odds of financial hardship (odds ratio, 0.82; 95% CI, 0.68-0.99; P = .04). However, this association was no longer significant after adjusting for financial literacy. Conclusions and Relevance: Results of this study showed that, despite a high level of health insurance literacy and financial literacy, the prevalence of financial hardship was high. Although there were lower odds of financial hardship with increased health insurance literacy, the association was no longer significant when financial literacy was added to the model, suggesting that a high level of financial literacy may help mitigate the adverse outcome of lower health insurance literacy levels in patients with cancer.

Longitudinal Patient Reported Outcomes with CAR-T Cell Therapy Versus Autologous and Allogeneic Stem Cell Transplant.

There are limited data on patient experience after chimeric antigen receptor (CAR) T-cell therapy, especially in comparison to autologous and allogeneic transplantation, which are more established forms of cellular therapy. We prospectively evaluated longitudinal patient-reported quality of life (QoL), symptom burden and cognition after CAR-T cell therapy and compared it with prospective cohorts of patients undergoing autologous stem cell transplantation (autoSCT) and allogeneic SCT (alloSCT). This was a single center study. The primary endpoint was change in QoL. Secondary endpoints were patient-reported adverse events (PRO-AEs) measured by Patient-Reported Outcomes version of the Common Terminology Criteria for Adverse Events (PRO-CTCAE) and cognitive function (NeuroQOLv2 questionnaire). Time profile of PRO-AEs was evaluated using longitudinal analysis, Toxicity over Time (ToxT). Patients completed questionnaires at baseline, week 2 and monthly for 6 months. One hundred four patients were evaluable (CAR-T: 34, autoSCT: 33, alloSCT: 37). Baseline QoL was similar across groups. We observed a short-term decline in QoL in all groups that gradually returned to baseline. The nadir in QoL was at week 2 and coincided with peak in symptom burden. The decline in overall QoL, physical and functional well-being was significantly less with CAR-T versus SCT groups and returned to baseline faster. Patients in the alloSCT group experienced the greatest symptom burden, greater decrease in performance status, largest short-term decline in QoL and slowest recovery. This study provides comprehensive data comparing QoL, PRO-AEs and cognition following CAR-T cell therapy versus autoSCT and alloSCT, and the first application of ToxT to PRO-CTCAE data. Short-term QOL, including physical and functional domains was better in the CAR-T group versus SCT groups, although all groups experienced an initial decline coinciding with peak symptoms. These data can serve as a guide for patient education, symptom management, and future studies in CAR-T cell therapy.

Impact of COVID-19 on Hematology-Oncology Fellowship Programs: A Quantitative and Qualitative Survey Assessment of Fellowship Program Directors.

PURPOSE: The COVID-19 pandemic led to unprecedented challenges in medical training, and we sought to assess the specific impact of COVID-19 on hematology-oncology (HO) fellowship programs. METHODS: We conducted a cross-sectional anonymous online survey of 103 HO program directors (PDs) in conjunction with the American Society of Hematology (ASH) and ASCO. We sought to assess the specific impact of COVID-19 on HO fellowship programs' clinical, educational, and research activities, evaluate perceptions regarding PD and trainee emotional and mental health, and identify ways to support programs. Data were analyzed using descriptive statistics, parametric and nonparametric tests, and multivariable logistic regression models. Responses to open-ended questions were analyzed with thematic analysis. RESULTS: Significant changes to fellowship activities included transitioning fellow training from outpatient clinics to telehealth (77.7%), shifting to virtual education (94.2%), and moving to remote research work (63.1%). A minority (21.4%) of PDs reported that their fellows were redeployed to cover non-HO services. Most PDs (54.4%) believed COVID-19 had a slight negative impact on fellowship training. PD self-reported burnout increased significantly from 15.5% prepandemic to 44.7% during the pandemic, and most PDs witnessed minor signs of fellow burnout (52.4%). Common PD concerns included inadequate supervision for telehealth activities, reduced opportunities for fellow advancement and promotion, lack of professional development activities, limited research operations and funding, program financial constraints, and virtual recruitment. CONCLUSION: We encourage institutions and national societies to allocate resources and develop programs that can support fellowships and mitigate the potential negative effects of COVID-19 on trainee and PD career development.

Impact of COVID-19 on Hematology-Oncology Trainees: A Quantitative and Qualitative Assessment.

PURPOSE: Graduate medical and research training has drastically changed during the COVID-19 pandemic, with widespread implementation of virtual learning, redeployment from core rotations to the care of patients with COVID-19, and significant emotional and physical stressors. The specific experience of hematology-oncology (HO) fellows during the COVID-19 pandemic is not known. METHODS: We conducted a mixed-methods study using a survey of Likert-style and open-ended questions to assess the training experience and well-being of HO fellows, including both clinical and postdoctoral trainee members of the American Society of Hematology and ASCO. RESULTS: A total of 2,306 surveys were distributed by e-mail; 548 (23.8%) fellows completed the survey. Nearly 40% of fellows felt that they had not received adequate mental health support during the pandemic, and 22% reported new symptoms of burnout. Pre-existing burnout before the pandemic, COVID-19-related clinical work, and working in a primary research or nonclinical setting were associated with increased burnout on multivariable logistic regression. Qualitative thematic analysis of open-ended responses revealed significant concerns about employment after training completion, perceived variable quality of virtual education and board preparation, loss of clinical opportunities to prepare for independent clinical practice, inadequate grant funding opportunities in part because of shifting research priorities, variable productivity, and mental health or stress during the pandemic. CONCLUSION: HO fellows have been profoundly affected by the pandemic, and our data illustrate multiple avenues for fellowship programs and national organizations to support both clinical and postdoctoral trainees.
