Abstract
BACKGROUND/AIMS Clinical guidelines should ideally be formulated from data representative of the population they are applicable to; however, historically, studies have disproportionally enrolled non-Hispanic White (NHW) patients, leading to potential inequities in care for minority groups. Our study aims to evaluate the extent to which racial minorities were represented in the United States Colorectal Cancer Surveillance Guidelines. METHODS We reviewed US guidelines between 1997 and 2020 and all identified studies cited by recommendations for surveillance after a baseline colonoscopy with no polyps, adenomas, sessile serrated polyps, and hyperplastic polyps. We analyzed the proportion of studies reporting race, and among these studies, we calculated the racial distribution of patients and compared the proportion of Non-NHW patients between each subtype. RESULTS For all guidelines, we reviewed 75 studies encompassing 9,309,955 patients. Race was reported in 24% of studies and 14% of total patients. Non-NHW comprised 43% of patients in studies for normal colonoscopies, compared with 9% for adenomas, 22% for sessile serrated polyps, and 15% for hyperplastic polyps. For the 2020 guidelines, we reviewed 33 studies encompassing 5,930,722 patients. Race was reported in 15% of studies and 21% of total patients. Non-NHW comprised 43% of patients in studies for normal colonoscopies, compared with 9% for tubular adenomas. Race was not cited for any other 2020 guideline. CONCLUSION Racial minorities are significantly underrepresented in US Colorectal Cancer Surveillance Guidelines, which may contribute to disparities in care. Future studies should prioritize enrolling a diverse patient population to provide data that accurately reflects their population.

Abstract
This study was designed to determine the enrollment patterns in breast cancer clinical trials (CCTs) of patients with diverse backgrounds in an equal access setting and to evaluate the factors contributing to low rates of clinical trial accrual in patients of low socioeconomic status (SES). We performed a retrospective review of a prospectively maintained database of new patients seen at the Dan L. Duncan Comprehensive Cancer Center dating from 5/2015 to 9/2021, which included 3043 patients screened for breast CCTs. We compared the rate of CCT availability, eligibility, and enrollment between two patient populations: Smith Clinic, where most patients are of low SES and uninsured, and Baylor St. Luke's Medical Center (BSLMC) with mostly predominantly insured, higher income patients. We performed logistic regression to evaluate whether differences in age, clinic, race, trial type, and primary language may be underlying the differences in CCT enrollment. More patients were eligible for CCTs at Smith Clinic (53.7% vs 44.7%, p < 0.001). However, Smith Clinic patients were more likely to decline CCT enrollment compared to BSLMC (61.3% declined vs 39.4%, p < 0.001). On multivariate analysis, Black patients had a significantly higher rate of CCT refusal overall (OR = 0.26, 95% CI 0.12-0.56, p < 0.001) and BSLMC only (OR = 0.20, 95% CI 0.060-0.60, p = 0.006). Our data shows that it is likely an oversimplification to assume that equal access will lead to the elimination of CCT disparities. Efforts to diversify CCTs must include consideration of structural and institutional inequities as well as social needs.

Psychosocial Factors That Influence a Woman's Decision to Enroll in a Clinical Trial: Implications on How to Improve Clinical Trial Enrollment Among Black Women. Int J Radiat Oncol Biol Phys 2024; 119:1347-1356. [PMID: 38387814 DOI: 10.1016/j.ijrobp.2024.02.017] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/05/2023] [Revised: 01/09/2024] [Accepted: 02/08/2024] [Indexed: 02/24/2024]
Abstract
PURPOSE Black women with breast cancer often present with more aggressive disease compared with other races, contributing to an increased risk of cancer mortality. Despite this inequity, Black women remain severely underrepresented in breast cancer clinical trials. We aim to characterize factors that influence a woman's decision to enroll in a clinical trial, with the goal of identifying clinical interventions to aid in the recruitment of vulnerable groups. METHODS AND MATERIALS A cross-sectional, descriptive study was conducted using a questionnaire adapted from 2 prevalidated surveys investigating factors influencing clinical trial enrollment. The survey was administered to women with curable breast cancer during a single follow-up visit at 4 different sites within a university medical system where all patients are screened for clinical trial eligibility. Chi-square tests and Mann-Whitney U tests were used to assess associations or differences between the populations. RESULTS One hundred ninety-four out of 209 women completed the survey, giving a compliance rate of 93%. Twenty-six percent of women self-identified as Black, most women were located at community sites (67.1%), most women had diagnoses of early-stage disease (I: 57.7%, II: 29.4%), and 81% of women had some collegiate-level education. Black women were younger at diagnosis (P = .005) and less likely to be married (P = .012) but more often lived with family members (P = .003) and had a lower median income (P < .001). According to the survey, Black women were less likely to trust their care team (P = .032), more likely to believe that research ultimately harms minorities (P < .001), and had a stronger belief in God's will determining illness and wellness (P < .001). Recurring themes of trust in the health care team, patient education, and advancement of cancer treatments were discussed in the focus groups. CONCLUSIONS Failure to offer clinical trials and mistrust in research institutions may pose the greatest hindrances to the enrollment of Black women in clinical trials. Empowering women through education and fostering trustworthy relationships can encourage greater clinical trial participation.

Abstract
Background Hypomethylating agents (HMAs) are guideline-recommended treatment for higher-risk myelodysplastic syndromes/neoplasms (MDS). However, a prior survey of patients with MDS reported challenges with intravenous (IV) and subcutaneous (SC) HMA therapies, including pain related to treatment administration and interference with daily activities; most patients also indicated a preference to switch to an oral therapy if one were available. Objectives This study evaluated the perspectives of US patients with MDS receiving oral decitabine/cedazuridine (DEC-C), an alternative to IV/SC HMAs. Methods An online survey was conducted among adult patients with MDS in the United States (10 November 2022 to 5 December 2022) who had filled a prescription for oral DEC-C between 2021 and 2022. Results A total of 150 patients completed the survey; 61% were aged ⩾60 years and 63% were male. Of these, 123 (82%) were still receiving oral DEC-C, and 27 (18%) had stopped oral DEC-C treatment. Half (50%) of patients had received oral DEC-C for ⩾6 months. The majority reported that treatment was convenient (83%) and that they were satisfied with treatment (86%). Most patients also reported very little/no interference with regular daily activities (82%), social activities (78%), and productivity (78%). When queried about negative impacts on quality of life (QOL), treatment side effects were the most commonly reported (30% of respondents). Among patients who had previously received IV/SC HMAs (n = 91), most agreed that oral DEC-C interfered less with daily life (91%) and had experienced improvement in QOL (85%) compared with previous treatment; 91% reported that oral DEC-C reduced the number of times they needed to travel to a healthcare facility. Conclusion Survey results suggest very little/no impact on regular daily activities and improved QOL with oral DEC-C relative to IV/SC HMAs, highlighting the potential for oral DEC-C to reduce the treatment burden associated with parenteral HMA therapy.

Abstract
Advances in cancer screening and treatment have improved survival after a diagnosis of cancer. As the number of cancer survivors as well as their overall life-expectancy increases, investigations of health-related quality of life (HRQOL) are critical in understanding the factors that promote the optimal experience over the course of survivorship. However, there is a dearth of information on determinants of HRQOL for African American cancer survivors as the vast majority of cohorts have been conducted predominantly among non-Hispanic Whites. In this review, we provide a review of the literature related to HRQOL in cancer survivors including those in African Americans. We then present a summary of published work from the Detroit Research on Cancer Survivors (ROCS) cohort, a population-based cohort of more than 5000 African American cancer survivors. Overall, Detroit ROCS has markedly advanced our understanding of the unique factors contributing to poorer HRQOL among African Americans with cancer. This work and future studies will help inform potential interventions to improve the long-term health of this patient population.

Abstract
BACKGROUND Triple-negative breast cancer (TNBC) is an aggressive subtype of breast cancer associated with shorter survival and a higher likelihood of recurrence. In early TNBC, platinum chemotherapy has been shown to improve pathological complete response (pCR); however, its effect on long-term survival outcomes has not been fully elucidated. METHODS Randomised controlled trials examining neoadjuvant or adjuvant platinum chemotherapy for early TNBC were included. Primary outcomes were disease-free survival (DFS) and overall survival (OS). Secondary outcomes were pCR, treatment adherence, grade III or IV toxicity related to chemotherapy, and quality of life. RESULTS From 3972 records, we included 20 published studies. All studies reporting DFS and OS used carboplatin. Inclusion of platinum chemotherapy improved DFS (neoadjuvant: hazard ratio (HR) 0.63, 95% confidence interval (CI) 0.53 to 0.75; adjuvant: HR 0.69, 95% CI 0.54 to 0.88) and OS (neoadjuvant: HR 0.69, 95% CI 0.55 to 0.86; adjuvant: 0.70, 95% CI 0.50 to 0.96). Our analysis confirmed platinum chemotherapy increased pCR rates (risk ratio (RR) 1.44, 95% CI 1.31 to 1.59). There were no differences seen in examined subgroups. Platinum chemotherapy was associated with reduced dose intensity and increased haematological toxicity. CONCLUSIONS Platinum-based chemotherapy using carboplatin in the adjuvant or neoadjuvant setting improves long-term outcomes of DFS and OS in early TNBC, with no evidence of differences by subgroup. This was at the cost of more frequent chemotherapy delays and dose reductions, and greater haematological toxicity. These findings support the use of platinum-based chemotherapy for people with early TNBC.

Abstract
Despite racial disparities in breast cancer mortality, Black women remain underrepresented in clinical trials. In this mixed methods research, 48 Black women were engaged via focus group discussions and in-depth interviews to better understand the lived experience of women with breast cancer. The results of this qualitative study informed the development of a subsequent online survey to identify barriers, motivators, and other factors that influence decision-making by Black women diagnosed with breast cancer when considering clinical trial participation. Among the 257 Black survey participants, most (95%) were aware of clinical trials; of those, most viewed them as lifesaving (81%) and/or benefiting others (90%). Negative perceptions such as serious side effects (58%), not receiving real treatment (52%), or risk of potential harm (62%) were indicated. Barriers included financial expenses (49%), concerns that their condition could be made worse (29%), that they would receive a placebo (28%), or that treatment was unapproved (28%). Participants were more likely than their health care providers (HCPs) to initiate discussions of clinical trials (53% versus 33%), and 29% of participants indicated a need for more information about risks and benefits, even after having those conversations. The most trustworthy sources of information on clinical trials were HCPs (66%) and breast cancer support groups (64%). These results suggest that trusted communities are key for providing education on clinical trials. However, there is also a need for HCPs to proactively discuss clinical trials with patients to ensure that they are adequately informed about all aspects of participation.

Abstract
BACKGROUND Medical mistrust, rooted in unethical research, is a barrier to cancer-related health care for Black/African American (AA) persons. Understanding trust, mistrust, and health care experiences is crucial, especially in multiple myeloma (MM), which disproportionately burdens Black/AA persons in incidence and survival. STUDY PURPOSE This study qualitatively examines the experiences of Black/AA and White dyads (patient with MM and adult caregiver) to gain insights into these phenomena. METHODS From November 2021 to April 2022, we recruited 21 dyads from the UNC Lineberger Comprehensive Cancer Center. Participants completed a sociodemographic survey and a 60-90 min semi-structured interview. We used ATLAS.ti v9 for project management and to facilitate data analysis using the Sort and Sift, Think and Shift approach (ResearchTalk Inc). RESULTS We interviewed 21 racially concordant dyads (11 Black/AA, 10 White) with mean patient ages of 70 (Black/AA) and 72 (White) at enrollment. Both Black/AA and White caregivers had a mean enrollment age of 68. The mean duration from MM diagnosis to enrollment for all patients was 5.5 years. Four key themes emerged: (1) knowledge and trust, (2) heightened emotions and discomfort, (3) differing mental constructs of health care experiences, and (4) mitigating mistrust, which varied by self-identified race. Black/AA participants had greater knowledge of historical events like the U.S. Public Health Service Untreated Syphilis Study at Tuskegee and carried the emotional burden longer. They also emphasized self-learning and self-guided research about MM for informed medical decision-making. Both Black/AA and White dyads emphasized the pivotal role of patient-provider relationships and effective communication in fostering trust and addressing concerns. CONCLUSION Our study offers contextual insights into the enduring challenges of medical mistrust, particularly within the Black/AA community, and its implications for patients and caregivers accessing and receiving MM-related care. Future studies should leverage these insights to guide the development of multilevel interventions addressing medical mistrust within the Black/AA community.

Abstract
BACKGROUND Little is known regarding the geographic disparity in the distribution of phase 1-3 clinical trials of new cancer treatments in the US and the associated factors. OBJECTIVE To examine county-level variation in the number of phase 1-3 cancer clinical trials and the associations between county characteristics and having phase 1-3 cancer clinical trials. METHODS We identified phase 1-3 cancer clinical trials started in the US between January 2008 and December 2022 from the Aggregate Analysis of ClinicalTrials.gov database. We analyzed the distribution of phase 1-3 cancer clinical trials at the county level. Using a mixed-effects regression with states as random intercepts, we estimated the associations between a county's median age, median household income, percentage of population from racial and ethnic minority groups, proportion of population aged 25 years or older with an educational attainment of bachelor's degree or higher, rurality, cancer incidence rate, and number of medical oncologists per population with having any phase 1-3 cancer clinical trial in a county. RESULTS After excluding trials that were suspended, terminated, and withdrawn, a total of 14,977 phase 1-3 cancer clinical trials started in the United States between January 2008 and December 2022 were included in the primary analysis. Only 1,333 out of 3,143 counties (42.4%) had 1 or more trial during this period. Counties that were rural, with lower median household income, a less educated population, fewer medical oncologists per population, and lower cancer incidence rates demonstrated a significantly lower likelihood of having phase 1-3 cancer clinical trials. CONCLUSIONS Our study revealed substantial geographic disparities in the distribution of phase 1-3 cancer clinical trials. Limited trial availability in low-income, low-education, low-oncologist, and rural areas can be a significant barrier to patient participation, potentially hindering adoption and worsening outcomes in disadvantaged populations.

Abstract
INTRODUCTION People from Black African Diaspora Communities (BAFDC) experience poorer health outcomes, have many long-term conditions and are persistently under-represented in health and care research. There is limited focus on programmes, or interventions that support inclusion and participation of people from BAFDC in research. Through coproduction, this realist review seeks to provide a programme theory explaining what context and mechanisms may be required, to produce outcomes that facilitate inclusion and participation for people from BAFDC in health and care research, in the UK. METHODS AND ANALYSIS A group of people from BAFDC with lived and professional experience, representing all levels of the health and care research system, will coproduce a realist review with a team of African-Caribbean, white British and white British of Polish origin health and care researchers. They will follow Pawson's five steps: (1) shaping the scope of the review; (2) searching for evidence; (3) document selection and appraisal; (4) data extraction and (5) data synthesis. The coproduction group will help to map the current landscape, identifying key issues that may inhibit or facilitate inclusion. Data will be extracted, analysed and synthesised following realist logic analysis, identifying and explaining how context and mechanisms are conceptualised in the literature and the types of contextual factors that exist and impact on inclusion and participation. Findings will be reported in accordance with Realist and Meta-narrative Evidence Synthesis Evolving Standards . ETHICS AND DISSEMINATION The coproduction group will agree an ethical approach considering accountability, responsibility and power dynamics, by establishing a terms of reference, taking a reflexive approach and coproducing an ethical framework. Findings will be disseminated to BAFDC and the research community through arts-based methods, peer-reviewed publications and conference presentations, agreeing a coproduced strategy for dissemination. Ethical review is not required. PROSPERO REGISTRATION NUMBER CRD42024517124.

Abstract
The treatment of multiple myeloma has evolved significantly over the past few decades with the development of novel therapeutics. The introduction of proteasome inhibitors, immunomodulatory drugs, monoclonal antibodies, and high-dose chemotherapy followed by hematopoietic stem cell transplantation has led to improved response rates and survival outcomes. The use of bispecific antibodies and chimeric antigen receptor T-cell therapy is currently under study, and early results are showing promise. Although outcomes for patients with MM have improved with the development of new treatments, there remains a subset of patients with high-risk disease who have a particularly poor prognosis. Therefore, it is critical that future clinical trials focus on developing new therapies specifically for high-risk multiple myeloma. Here we review the literature and provide guidance on treating patients with multiple myeloma for practicing oncologists.

Abstract
BACKGROUND Recruitment of cancer clinical trial (CCT) participants, especially participants representing the diversity of the US population, is necessary to create successful medications and a continual challenge. These challenges are amplified in Phase I cancer trials that focus on evaluating the safety of new treatments and are the gateway to treatment development. In preparation for recruitment to a Phase I recurrent head and neck cancer (HNC) trial, we assessed perceived barriers to participation or referral and suggestions for recruitment among people with HNC and community physicians (oncologist, otolaryngologist or surgeon). METHODS Between December 2020 and February 2022, we conducted a qualitative needs assessment via semistructured interviews with a race and ethnicity-stratified sample of people with HNC (n = 30: 12 non-Hispanic White, 9 non-Hispanic African American, 8 Hispanic and 1 non-Hispanic Pacific Islander) and community physicians (n = 16) within the University of Florida Health Cancer Center catchment area. Interviews were analyzed using a qualitative content analysis approach to describe perspectives and identify relevant themes. RESULTS People with HNC reported thematic barriers included: concerns about side effects, safety and efficacy; lack of knowledge and systemic and environmental obstacles. Physicians identified thematic barriers of limited physician knowledge; clinic and physician barriers and structural barriers. People with HNC and physicians recommended themes included: improved patient education, dissemination of trial information and interpersonal communication between community physicians and CCT staff. CONCLUSIONS The themes identified by people with HNC and community physicians are consistent with research efforts and recommendations on how to increase the participation of people from minoritized populations in CCTs. This community needs assessment provides direction on the selection of strategies to increase CCT participation and referral. PATIENT OR PUBLIC CONTRIBUTION This study focused on people with HNC and community physicians' lived experience and their interpretations of how they would consider a future Phase I clinical trial. In addition to our qualitative data reflecting community voices, a community member reviewed the draft interview guide before data collection and both people with HNC and physicians aided interpretation of the findings.

Abstract
The COVID-19 pandemic halted many in-person programs of research and required researchers to pivot to technology-enhanced approaches. To date, there are no examples or guidelines on how to use technology to implement health promotion programs rooted in the community-based participatory research (CBPR) model among low-income older Black adults. The aims of this paper are (a) to describe and report on the health-related outcomes of an in-person CBPR model-based health promotion intervention program for older Black adults in a low-income community, and (b) to describe the process of adapting this program to a technology-enhanced and Zoom-delivered format and provide preliminary evidence on the health-related outcomes and acceptability of this program. This paper highlights the potential benefits of a technology-enhanced and Zoom-delivered health promotion program among low-income older Black adults and provides recommendations to optimize such efforts to foster these benefits. These recommendations are aligned with the four domains of the CBPR model (i.e., contexts, partnership processes, intervention and research, and outcomes). We conclude that CBPR model-based, technology implemented health promotion interventions for low-income older Black adults are acceptable to such adults and should attend to the values, perspectives, and preferences of these individuals. The information in this manuscript is relevant to health promotion specialists at this seemingly ongoing though post-pandemic era because technology-enhanced interventions are scalable and cost-effective and those anchored in CBPR are well-positioned to promote health equity.

Abstract
African American adults have the highest mortality rate for most cancers in the United States, and meaningful, community-driven research is needed to inform optimal strategies for addressing these disparities. Unfortunately, research mistrust, often driven by historical inequities, is well-documented among African Americans.This study explored trust, attitudes, and preferences regarding participation in cancer research activities among primarily African American and other medically underserved communities in South Carolina from August 2020 to December 2021. Trust was measured using the Trust in Medical Researchers Scale (TMRS).The mean TMRS score for all study participants (N = 179) was 26.54 (SD 7.57) out of 48 (maximum possible score). Significant differences in mean values of the TMRS scores were only observed for gender (p = 0.0056) and race (p < 0.0001), with White participants and males reporting higher levels of trust in medical researchers. Overall, 52.5% of participants were somewhat likely or likely to volunteer to participate in a cancer research opportunity, with White participants (73.81%) being more likely to participate in cancer research compared to African American participants (45.74%) (p = 0.0054). Furthermore, participants were most willing to provide saliva (80.85%) and urine samples (80.85%), new blood samples (60.64%), stool samples (54.26%), medical records or laboratory results (52.13%) and least willing to allow left-over blood, tissue, or other fluids from medical procedures to be used for research (50%).These results provide evidence of the need for concerted programmatic efforts to build trust in cancer researchers, particularly among females and African American adults.

Abstract
BACKGROUND We investigate the geographical and racial disparities in accessing CAR-T and bispecific antibodies trials for DLBCL. MATERIALS AND METHODS ClinicalTrials.gov was searched, and 75 trials with at least 1 open site in the US were included. 2020 US Census Bureau data was used to obtain data on race and ethnicity. SPSS version 26 was used for analysis. RESULTS There were 62 CAR-T and 13 bispecific antibodies trials with 6221 enrolled or expected to enroll patients. Eighty-five percent of the clinical trials were only open in the US, and the majority 64% were pharmaceutical-funded. There were 126 unique study sites distributed over 31 states with 11 (0-51) mean number of trials per state and 4.5 (1-26) and 4.4 (1-24) mean number of CAR-T and bispecific antibodies trials per site, respectively. Southern states had the most number of trials 31%, followed by Midwestern 25%, Northeastern 24%, and Western 20%. The highest number of study locations were in California 13, New York 9, and Pennsylvania 9, while the highest number of open studies were in California 51, Texas 32, and New York 23. Twenty states had no open CAR-T or bispecific antibodies trials. Only 33% of African Americans (AA) lived in a county with a trial, and 7 out of 10 states with the highest proportion of AA residents (18.6%-41.4%) have no or less than 4 trial sites. Of the 62 counties analyzed, 92% were White predominant, while only 8% were AA predominant (P = .009). CONCLUSIONS Strategies should be framed to address the observed disparities and to improve access.

Abstract
The representation of racial and ethnic minority populations in clinical trials continues to be a challenge despite mandates, good intentions, and concerted efforts by funding agencies, regulatory bodies, and researchers to close the clinical trials gap. A lack of diversity in research results in both continued disparities and poorer health outcomes. It is thus imperative that investigators understand and effectively address the challenges of clinical trials participation by underrepresented populations. In this paper, we expound on best practices for participatory research by clearly defining the community, highlighting the importance of proper identification and engagement of strong community partners, and exploring patient- and provider-level barriers and facilitators that require consideration. A clearer understanding of the balance of power between researchers and community partners is needed for any approach that addresses clinical trials representation. Unintended biases in study design and methods may continue to prevent racial and ethnic minority participants from taking part, and significant organizational changes are necessary for efficient and transparent relationships. Comprehensive community engagement in research includes dissemination of clinical trial results within and in partnership with community partners. Through careful deliberation and honest reflection, investigators, institutions, and community partners can develop the tailored blueprints of research collaborations essential for true equity in clinical trials.

Abstract
Black and Latino/Hispanic populations are disproportionately impacted by multiple myeloma (MM) in the United States and are underrepresented in many clinical trials. The Multiple Myeloma Research Foundation sponsored a 1-day workshop of 46 experts spanning the ecosystem of MM research and care, including government, academia, nonprofits, pharma/biotech, community partners, and retail pharmacy. Specific, tangible steps to overcome the well-documented barriers to improving the diversity and inclusivity of clinical trials were discussed, including broadening inclusion/exclusion criteria, reducing the financial and other burdens of trial participants, selecting diverse study sites, including implicit bias training, and taking steps to empower patients.

Abstract
OBJECTIVE To examine the performance of the Palacios et al [Aguilar Palacios D, Wilson B, Ascha M, et al. New baseline renal function after radical or partial nephrectomy: a simple and accurate predictive model. J Urol. 2021;205:1310-1320] post-nephrectomy future glomerular function rate (fGFR) equation in a diverse cohort using both the Chronic Kidney Disease Epidemiology (CKD-EPI) 2009 equation with race, used in the creation of the formula, as well as the CKD-EPI 2021 equation without race. METHODS Patients who underwent partial or radical nephrectomy for renal cell carcinoma from 2005-2021 were identified in our institutional database. Patients with creatinine values preoperatively and 3-12 months postoperatively were included. Correlation/bias/accuracy/precision of the fGFR equation (fGFR = 35+ [preoperative eGFR × 0.65] - 18 [if radical] - [age × 0.25] + 3 [if tumor >7 cm] - 2 [if diabetes]) with observed postoperative eGFR was determined by both the CKD-EPI-2021 and CKD-EPI 2009 equations. RESULTS A total of 1443 patients were analyzed. Seventy-one percent (1024) were White and 22.9% (331) were Black. Most underwent radical nephrectomy (60.3%). 40% T3-T4 renal cell carcinoma (RCC), with 14.8% of patients having M1 disease. Median observed vs predicted fGFR was 58.0 vs 58.7 mL/min/1.73 m2 for CKD-EPI 2021 and 56.0 vs 57.5 for CKD-EPI 2009. For the total cohort, the correlation/bias/accuracy/precision of the fGFR equation was 0.805/-0.5/81.7/7.9-9.0 for CKD-EPI 2021 and 0.809/-0.8/81.3/-8.1 to 8 for CKD-EPI 2009. In Black patients, fGFR equation demonstrated >75% accuracy with both CKD-EPI equations; however, accuracy was lower in black patients with the CKD-EPI2021 equation (76.1% vs 83.4%, P = .003). CONCLUSION The fGFR equation performed well in our large, diverse cohort, though accuracy was relatively lower when using CKD-EPI 2021 compared to CKD-EPI 2009.

Abstract
Despite advances in screening, diagnosis, and treatment for prostate cancer (PCa), Black men tend to be diagnosed at younger ages, have higher mortality rates, and are at increased risk of recurrence or metastasis compared to their White counterparts. PCa disparities among Black men are caused by a complex interaction of social, behavioral, and biological factors across the public policy, community, organizational, interpersonal, and individual levels. Key contributing factors include mistrust in the health care system, poor communication between patients and providers, low awareness of screening guidelines, and high medical costs. These disparities are further exacerbated by the low representation of Black men in clinical trials, which limits access to high-quality cancer care and generalizability for PCa treatments. In this narrative review of the existing literature, we examined the epidemiology and identified contributing factors, and propose multi-level strategies to address and mitigate disparities among Black men with PCa.

Abstract
Importance There has been little consideration of genomic risk of recurrence by breast cancer subtype despite evidence of racial disparities in breast cancer outcomes. Objective To evaluate associations between clinical trial end points, namely pathologic complete response (pCR) and distant recurrence-free survival (DRFS), and race and examine whether gene expression signatures are associated with outcomes by race. Design, Setting, and Participants This retrospective cohort study used data from the Investigation of Serial Studies to Predict Your Therapeutic Response With Imaging and Molecular Analysis 2 (I-SPY 2) multicenter clinical trial of neoadjuvant chemotherapy with novel agents and combinations for patients with previously untreated stage II/III breast cancer. Analyses were conducted of associations between race and short- and long-term outcomes, overall and by receptor subtypes, and their association with 28 expression biomarkers. The trial enrolled 990 female patients between March 30, 2010, and November 5, 2016, with a primary tumor size of 2.5 cm or greater and clinical or molecular high risk based on MammaPrint or hormone receptor (HR)-negative/ERBB2 (formerly HER2 or HER2/neu)-positive subtyping across 9 arms. This data analysis was performed between June 10, 2021, and October 20, 2022. Exposure Race, tumor receptor subtypes, and genomic biomarker expression of early breast cancer. Main Outcomes and Measures The primary outcomes were pCR and DRFS assessed by race, overall, and by tumor subtype using logistic regression and Cox proportional hazards regression models. The interaction between 28 expression biomarkers and race, considering pCR and DRFS overall and within subtypes, was also evaluated. Results The analytic sample included 974 participants (excluding 16 self-reporting as American Indian or Alaska Native, Native Hawaiian or Other Pacific Islander, or multiple races due to small sample sizes), including 68 Asian (7%), 120 Black (12%), and 786 White (81%) patients. Median (range) age at diagnosis was 47 (25-71) years for Asian, 49 (25-77) for Black, and 49 (23-73) years for White patients. The pCR rates were 32% (n = 22) for Asian, 30% for Black (n = 36), and 32% for White (n = 255) patients (P = .87). Black patients with HR-positive/ERBB2-negative tumors not achieving pCR had significantly worse DRFS than their White counterparts (hazard ratio, 2.28; 95% CI, 1.24-4.21; P = .01), with 5-year DRFS rates of 55% (n = 32) and 77% (n = 247), respectively. Black patients with HR-positive/ERBB2-negative tumors, compared with White patients, had higher expression of an interferon signature (mean [SD], 0.39 [0.87] and -0.10 [0.99]; P = .007) and, compared with Asian patients, had a higher mitotic score (mean [SD], 0.07 [1.08] and -0.69 [1.06]; P = .01) and lower estrogen receptor/progesterone receptor signature (mean [SD], 0.31 [0.90] and 1.08 [0.95]; P = .008). A transforming growth factor β signature had a significant association with race relative to pCR and DRFS, with a higher signature associated with lower pCR and worse DRFS outcomes among Black patients only. Conclusions and Relevance The findings show that women with early high-risk breast cancer who achieve pCR have similarly good outcomes regardless of race, but Black women with HR-positive/ERBB2-negative tumors without pCR may have worse DRFS than White women, highlighting the need to develop and test novel biomarker-informed therapies in diverse populations.

Abstract
BACKGROUND Black men and other minoritized populations have represented 4-5% or less of participants in most practice-informing clinical trials. This study sought to assess the knowledge, attitudes, and practices of clinicians around equity and inclusion in prostate cancer clinical trial initiatives in the United States. METHODS An anonymous, web-based questionnaire was administered via REDCap (Research Electronic Data Capture) with questions focused on inclusivity of minoritized populations with respect to race and ethnicity in prostate cancer clinical trials research. The survey link was distributed across the United States via several professional organizations, prostate cancer groups, and social media. Responses were analyzed both quantitatively (descriptive statistics) and qualitatively (thematic analysis). RESULTS Overall, 131 respondents completed the survey (70% self-identified as White, 17% as Asian, and 6% as Black). Most respondents practiced in an urban setting (89%). Of those who engaged in outreach with minoritized communities during the trial design process, 69% observed improved enrollment of minoritized populations. However, 18% of respondents noted that outreach alone does not overcome existing structural barriers to participation in clinical trials. Thematic analysis identified four key areas to address for improving equity: structural, health system, trial-/study-specific, and relationship-/engagement-related factors. CONCLUSION Study participants demonstrated a knowledge of the importance of improving equity in prostate cancer clinical trials research. Designing trials that reduce issues associated with access and improving community outreach were emphasized as key focus areas for reducing health disparities in prostate cancer clinical trials research.

Abstract
BACKGROUND Black patients with cancer are less likely to receive precision cancer treatments than White patients and are underrepresented in clinical trials. To address these disparities, the study aimed to develop and pilot-test a digital intervention to improve Black patients' knowledge about precision oncology and clinical trials, empower patients to increase relevant discussion, and promote informed decision-making. METHODS A community-engaged approach, including a Community Advisory Board and two rounds of key informant interviews with Black patients with cancer, their relatives, and providers (n = 48) was used to develop and refine the multimedia digital intervention. Thematic analysis was conducted for qualitative data. The intervention was then pilot-tested with 30 Black patients with cancer to assess feasibility, acceptability, appropriateness, knowledge, decision self-efficacy, and patient empowerment; Wilcoxon matched pairs signed-rank test was used to analyze quantitative data. RESULTS The digital tool was found to be feasible, acceptable, and culturally appropriate. Key informants shared their preferences and recommendations for the digital intervention and helped improve cultural appropriateness through user and usability testing. In the pilot test, appreciable improvement was found in participants' knowledge about precision oncology (z = -2.04, p = .052), knowledge about clinical trials (z = -3.14, p = .001), and decisional self-efficacy for targeted/immune therapy (z = -1.96, p = .0495). CONCLUSIONS The digital intervention could be a promising interactive decision-support tool for increasing Black patients' participation in clinical trials and receipt of precision treatments, including immunotherapy. Its use in clinical practice may reduce disparities in oncology care and research. PLAIN LANGUAGE SUMMARY We developed a digital interactive decision support tool for Black patients with cancer by convening a Community Advisory Board and conducting interviews with Black patients with cancer, their relatives, and providers. We then pilot-tested the intervention with newly diagnosed Black patients with cancer and found appreciable improvement in participants' knowledge about precision oncology, knowledge about clinical trials, and confidence in making decisions for targeted/immune therapy. Our digital tool has great potential to be an affordable and scalable solution for empowering and educating Black patients with cancer to help them make informed decisions about precision oncology and clinical trials and ultimately reducing racial disparities.

Abstract
BACKGROUND Multiple myeloma (MM) is an incurable debilitating blood cancer associated with the lowest health related quality of life (HRQoL) of all cancers. With nearly 88% of adults aged ≥55 years at diagnosis, age-associated physical losses, comorbidities, and social factors contribute to worsening HRQoL. This qualitative study assessed dyadic (patient-informal caregiver) perspectives on the factors contributing to HRQoL in MM survivors. METHODS We recruited 21 dyads from the UNC-Chapel Hill Lineberger Comprehensive Cancer between 11/2021 and 04/2022. Participants completed a single dyadic semistructured interview capturing broad perspectives on MM. We used ATLAS. ti v 9 for project management and to facilitate data analysis using the Sort and Sift, Think and Shift approach (ResearchTalk, Inc.). This iterative approach allowed the exploration and identification of themes within and across transcripts. RESULTS The mean age at enrollment was 71 years (median: 71, range: 57-90) for patients and 68 years (median 67, range: 37-88) for caregivers. All dyads were racially concordant (11 Black/AA and 10 White). However, we aggregated the findings due to no consistent racial differences. Six themes related to (1) physical burden, (2) treatment challenges, (3) losses of independence, (4) caregiver burden, (5) patient and caregiver perseverance, and (6) adjustment to a new normal were identified. Dyads also experienced MM together, resulting in patients and caregivers experiencing changes in their ability to engage in physical and social activities, which further contributed to poor HRQoL. Patients' increased need for social support led to shifts in the caregiver roles, resulting in caregivers feeling burdened by their responsibilities. All dyads acknowledged the need for perseverance and adaptability to a new normal with MM. CONCLUSION The functional, psychosocial, and HRQoL of older patients with MM and their caregivers remain impacted ≥6 months after a new diagnosis highlighting clinical and research opportunities to focus on preserving or improving the health of dyads living with MM.

Abstract
Growing evidence has demonstrated significant, persistent, and widespread disparities in cancer clinical trial enrollment across myriad disease sites and target populations. Although mechanisms underlying such disparities are complex and multifactorial, clinical trial eligibility criteria may serve as a key structural barrier to equitable and diverse trial enrollment. In this review, we provide an overview of the data describing historical and current disparities in cancer clinical trial enrollment and subsequently describe several patient-, institution-, and trial-related factors which appear to be key drivers of enrollment inequity, with specific discussion regarding the impact of eligibility criteria. We further describe the landscape of ongoing professional efforts aimed at eliminating clinical trial disparities through various medical, professional, and advocacy groups. The review concludes with a practical discussion of how modernization of eligibility criteria in clinical trials may decrease or eliminate trial disparities, including specific actionable recommendations aimed at improving the quality of future eligibility criteria.

Abstract
OBJECTIVE Describe the demographic profile of US participants in Amgen clinical trials over a 10-year period and variations across therapeutic areas, indications, and geographies. METHODS Cross-sectional retrospective study including participants enrolled (2005-2020) in phase 1-3 trials completed between January 1, 2012 and June 30, 2021. RESULTS Among 31,619 participants enrolled across 258 trials, one-fifth represented racial minority populations (Asian, 3%; Black or African American, 17%; American Indian or Alaska Native, Native Hawaiian or Other Pacific Islander, multiracial, each < 1%); fewer than one-fifth (16%) represented an ethnic minority population (Hispanic or Latino). Compared with census data, representation of racial and ethnic groups varied across US states. Across most therapeutic areas (bone, cardiovascular, hematology/oncology, inflammation, metabolic disorders, neuroscience) except nephrology, participants were predominantly White (72-81%). A similar proportion of males and females were enrolled between 2005 and 2016; male representation was disproportionately higher than female between 2016 and 2020. Across most medical indications, the majority of participants were 18-65 years of age. CONCLUSIONS AND RELEVANCE While the clinical research community is striving to achieve diversity and proportional representation across clinical trials, certain populations remain underrepresented. Our data provide a baseline assessment of the diversity and representation of US participants in Amgen-sponsored clinical trials and add to a growing body of evidence on the importance of diversity in clinical research. These data provide a foundation for strategies aimed at supporting more equitable and representative research, and a baseline from which to assess the impact of future strategies to advance health equity.

Abstract
Plasma cell leukemia (PCL) is a rare, aggressive subtype of multiple myeloma (MM) with a poor prognosis. Prior studies have shown that racial disparities affect MM patients in various ways, which may affect patients' outcomes. In this study, we aimed to investigate racial differences in hospitalization outcomes for PCL using Nationwide Inpatient Sample data. Overall, hospitalization rates for PCL tended to decrease over the past decade. Among hospitalized patients with a primary diagnosis of PCL, there was no statistically significant association between race/ethnicity and hospitalization rates, between NH-White patients and NH-Black patients (OR 1.94; 95%CI 0.3-3.54, p 0.95), and Hispanic patients (OR 0.47; 95% CI 0.05-4.23, p 0.5). Additionally, there was no significant association between race/ethnicity and inpatient mortality. The overall lower incidence of PCL, more significant disease burden, and poor prognosis across all groups may contribute to our findings. With increasing evidence that PCL is cytogenetically distinct from MM, more investigation into biological and sociodemographic factors that affect healthcare utilization and treatment outcomes should be carried out.

Abstract
BACKGROUND Triple-negative breast cancer (TNBC) is an aggressive subtype of breast cancer associated with shorter survival and a higher likelihood of the cancer returning. In early TNBC, platinum-based chemotherapy has been shown to improve pathological complete response (pCR); however, its effect on long-term survival outcomes has not been fully elucidated and recommendations to include platinum chemotherapy are not consistent in international guidelines. OBJECTIVES To evaluate the benefits and harms of platinum-based chemotherapy as adjuvant and neoadjuvant treatment in people with early triple-negative breast cancer. SEARCH METHODS We used standard, extensive Cochrane search methods. The latest search date was 4 April 2022. SELECTION CRITERIA We included randomised controlled trials examining neoadjuvant or adjuvant platinum chemotherapy for early TNBC. DATA COLLECTION AND ANALYSIS We used standard Cochrane methods. Our primary outcomes were disease-free survival (DFS) and overall survival (OS). Our secondary outcomes were pCR, treatment adherence, grade III or IV toxicity related to chemotherapy, and quality of life. Prespecified subgroups included BRCA mutation status, homologous recombination deficiency (HRD) status, frequency of chemotherapy, type of platinum agent used, and the presence or absence of anthracycline chemotherapy. We assessed risk of bias using Cochrane's RoB 1 tool and certainty of evidence using the GRADE approach. MAIN RESULTS From 3972 records, we included 20 published studies involving 21 treatment comparisons, and 25 ongoing studies. For most domains, risk of bias was low across studies. There were 16 neoadjuvant chemotherapy studies (one of which combined neoadjuvant and adjuvant therapy) and four adjuvant chemotherapy trials. Most studies used carboplatin (17 studies) followed by cisplatin (two), and lobaplatin (one). Eight studies had an anthracycline-free intervention arm, five of which had a carboplatin-taxane intervention compared to an anthracycline-taxane control. All studies reporting DFS and OS used carboplatin. Inclusion of platinum chemotherapy improved DFS in neoadjuvant and adjuvant settings (neoadjuvant: hazard ratio (HR) 0.63, 95% confidence interval (CI) 0.53 to 0.75; 7 studies, 8 treatment comparisons, 1966 participants; high-certainty evidence; adjuvant: HR 0.69, 95% CI 0.54 to 0.88; 4 studies, 1256 participants; high-certainty evidence). Platinum chemotherapy in the regimen improved OS (neoadjuvant: HR 0.69, 95% CI 0.55 to 0.86; 7 studies, 8 treatment comparisons, 1973 participants; high-certainty evidence; adjuvant: 0.70, 95% CI 0.50 to 0.96; 4 studies, 1256 participants; high-certainty evidence). Median follow-up for survival outcomes ranged from 36 to 97.6 months. Our analysis confirmed platinum chemotherapy increased pCR rates (risk ratio (RR) 1.44, 95% CI 1.31 to 1.59; 15 studies, 16 treatment comparisons, 3083 participants; high-certainty evidence). Subgroup analyses showed no evidence of differences in DFS according to BRCA mutation status, HRD status, lymph node status, or whether the intervention arm contained anthracycline chemotherapy or not. Platinum chemotherapy was associated with reduced dose intensity, with participants more likely to require chemotherapy delays (RR 2.23, 95% CI 1.70 to 2.94; 4 studies, 5 treatment comparisons, 1053 participants; moderate-certainty evidence), dose reductions (RR 1.77, 95% CI 1.56 to 2.02; 7 studies, 8 treatment comparisons, 2055 participants; moderate-certainty evidence) and early cessation of treatment (RR 1.20, 95% CI 1.04 to 1.38; 16 studies, 17 treatment comparisons, 4178 participants; moderate-certainty evidence). Increased haematological toxicity occurred in the platinum group who were more likely to experience grade III/IV neutropenia (RR 1.53, 95% CI 1.43 to 1.63; 19 studies, 20 treatment comparisons, 4849 participants; moderate-certainty evidence), anaemia (RR 8.20, 95% CI 5.66 to 11.89; 18 studies, 19 treatment comparisons, 4757 participants; moderate-certainty evidence) and thrombocytopenia (RR 7.59, 95% CI 5.10 to 11.29; 18 studies, 19 treatment comparisons, 4731 participants; moderate-certainty evidence). There was no evidence of a difference between chemotherapy groups in febrile neutropenia (RR 1.16, 95% CI 0.89 to 1.49; 11 studies, 3771 participants; moderate-certainty evidence). Renal impairment was very rare (0.4%, 2 events in 463 participants; note 3 studies reported 0 events in both arms; 4 studies; high-certainty evidence). Treatment-related death was very rare (0.2%, 7 events in 3176 participants and similar across treatment groups; RR 0.58, 95% 0.14 to 2.33; 10 studies, 11 treatment comparisons; note 8 studies reported treatment-related deaths but recorded 0 events in both groups. Thus, the RR and CIs were calculated from 3 studies rather than 11; 3176 participants; high-certainty evidence). Five studies collected quality of life data but did not report them. AUTHORS' CONCLUSIONS Platinum-based chemotherapy using carboplatin in the adjuvant or neoadjuvant setting improves long-term outcomes of DFS and OS in early TNBC, with no evidence of differences by subgroup. This was at the cost of more frequent chemotherapy delays and dose reductions, and greater haematological toxicity, though serious adverse events including neuropathy, febrile neutropenia or treatment-related death were not increased. These findings support the use of platinum-based chemotherapy for people with early TNBC. The optimal dose and regimen are not defined by this analysis, but there is a suggestion that similar relative benefits result from the addition of carboplatin to either anthracycline-free regimens or those containing anthracycline agents.

Cancer Med 2023; 12:18098-18109. [PMID: 37519123 PMCID: PMC10524029 DOI: 10.1002/cam4.6370] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/25/2023] [Revised: 06/25/2023] [Accepted: 07/16/2023] [Indexed: 08/01/2023] Open
Abstract
BACKGROUND Racial differences have been reported in toxicity outcomes for anticancer drug treatments. However, these observations were often from studies with small sample sizes, and many only reported the maximum grade of toxicity and no longitudinal information. This current analysis aims to investigate racial differences in longitudinal toxicities using a large-scale clinical trials database. METHODS Early-phase clinical trials sponsored by the Cancer Therapy Evaluation Program at the National Cancer Institute, USA, that evaluated cytotoxic drugs and molecularly targeted agents between March 2000 and December 2012 were studied. Race was categorized as White, Black or African-American, and Asian. Each toxicity's grade prevalence, mean grade at each cycle, and time to develop grade 2 or higher toxicity was evaluated. RESULTS In total, 25,442 patients from 697 trials were included in this study. The number of patients categorized as White, Black, and Asian designations was 22,756 (89%), 1874 (7%), and 812 (3%), respectively. Notable findings include the rate of any grade of diarrhea in Black people was 26% and 21% lower than that of White and Asian people. The median time to the first grade 2 or higher event was 6 cycles in White people, 8 in Black people, and 6 in Asian people. The rate of any grade hyperglycemia was significantly higher in Asian people. CONCLUSIONS Although we identified several racial differences in longitudinal toxicities, most were of generally lower grade. Further study is needed to clarify the cause of racial differences in treatment-associated toxicities.

Abstract
INTRODUCTION Multiple myeloma (MM) is more common in Black persons when compared to non-Hispanic White persons. The International Myeloma Working Group (IMWG) provides consensus for diagnosis and treatment of MM. Our study aimed to assess the racial composition of supporting studies used by IMWG to publish their guidelines METHODS: We performed a cross sectional study that included all IMWG publications up to July 2022. References cited in each publication were reviewed. Review articles, comments, editorials, case reports, and animal-based studies were excluded. RESULTS A total of 59 IMWG publications with 3956 references were reviewed. Final analysis included 2047 references of which 39 % (n = 804) were clinical trials, 35 % (n = 712) were observational studies, 20 % (n = 401) were diagnostic and or genetic testing-based studies, 3 % (n = 65) were population-based analysis and 3 % (n = 65) classified as others. Only 10.4 % of included references (n = 213/2047) reported race/ethnicity of studied patients. The total number of patients in all referenced studies were 5,747,920, only 2.6 % (n = 150,790) black patients. Of the trials referenced and done exclusively in the US, 41 out of 282 (14.5 %) reported race/ethnicity with a total number of patients of 38,050 of which 2493 (6.5 %) were black patients. CONCLUSION IMWG guidelines were based mainly on studies that did not include enough Black patients. Guidelines should consider inclusion of observational, diagnostic and population-based studies with more black patients to allow for better reflection of disease prevalence, clinical characteristics and/or outcomes.

Abstract
BACKGROUND Black breast and ovarian cancer patients are underrepresented in clinical cancer trials disproportionate to the prevalence of these cancers in Black females. Historically, lower enrollment has been attributed to individualized factors, including medical mistrust, but more recently structural factors, including systemic racism, have received additional scrutiny. We interviewed Black women with a personal or family history of breast and ovarian cancer to understand their views and experiences related to research participation. METHODS Qualitative interviews were conducted via telephone or video conference and transcribed verbatim. Transcripts were qualitatively analyzed for iterative themes related to the offer and participation in cancer clinical trials and research studies, impact on cancer care, and recommendations to increase enrollment of Black patients. RESULTS Sixty-one Black women completed an interview. Participants expressed that Black women are underrepresented in cancer research, and that this negatively impacted their own care. Many cited past historical abuses, including the Tuskegee syphilis trial, as a potential factor for lower enrollment but suggested that lower enrollment was better understood in the context of the entirety of their healthcare experiences, including present-day examples of patient mistreatment or dismissal. Participants suggested that proactive community engagement, transparency, and increased representation of Black research team members were strategies likely to foster trust and bolster research participation. CONCLUSION(S) Medical mistrust is only a partial factor in the lower participation of Black patients in cancer research. Researchers should implement the strategies identified by our participants to promote diverse enrollment and ensure that Black patients are included in future therapeutic advances.

Examining participant representation by sex, race, ethnicity and age in United States blood donation and blood transfusion clinical trials. Transfus Apher Sci 2023:103653. [PMID: 36781328 DOI: 10.1016/j.transci.2023.103653] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/17/2022] [Revised: 02/03/2023] [Accepted: 02/07/2023] [Indexed: 02/11/2023]
Abstract
Significant inequities based on sex, race, ethnicity, and age exist among participants in clinical trials dedicated to investigating medical disease states. While general demographic data regarding blood donors and blood transfusion recipients have been studied extensively, the demographics of participants involved in blood donation and blood transfusion clinical trials are unknown. We performed a cross-sectional analysis of United States (U.S.) -based interventional blood donation and blood transfusion clinical trials registered with Clinicaltrials.gov to ascertain the composition of participants' sex, race, ethnicity, and age, as well as diagnostic conditions and geographic trial locations.Eligible trials were undertaken between July 2003 and August 2020. Thirty-eight of the one hundred and fifty-two blood donation and blood transfusion clinical trials met inclusion criteria (seven blood donation and thirty-one blood transfusion trials). While the participant dataset from trial reports were incomplete, 100 % of blood donation trials reported sex and age, 71.4 % reported race, and 42.3 % reported ethnicity. 96.8 % of blood transfusion trials reported sex, 51.6 % reported race, 38.7 % reported ethnicity, and 100 % reported age. Among 2720 participants enrolled in the seven blood donation trials, females were underrepresented (28.5 %) compared to U.S. Census data. Conversely, female (50.8 %) and male participants (49.2 %) were equally represented in blood transfusion trials (9255 participants). White participants were overrepresented in blood donation trials (73.4 %), while Hispanic or Latinos were underrepresented in both blood donation (7.7 %) and blood transfusion (8.2 %) trials compared to 2019 U.S.Census data. Only 8.3 % of blood transfusion clinical trials open to adults reported including older adults (i.e., ≥ 65yo). Despite mandatory reporting requirements and an already established framework, researchers frequently failed to report complete demographics of blood donation and blood transfusion clinical trial participants. Furthermore, various demographic groups were underrepresented in blood donation and/or blood transfusion clinical trials, including females, Hispanic or Latino individuals, and older adults. These findings demonstrate the need for implementation of strategies to ensure equitable representation of individuals in blood donation and transfusion clinical trials.

Abstract
PURPOSE Residents of communities facing social vulnerability (eg, poverty) have limited access to clinical trials, leaving them susceptible to experiencing poor health outcomes. We examined the association between North Carolina county-level social vulnerability and available multiple myeloma (MM) trials. METHODS Using a novel data linkage between ClinicalTrials.gov, the 2019 American Community Survey, and the Centers for Disease Control and Prevention's Social Vulnerability Index, we investigated at the county level (1) availability of MM trial sites and (2) the relationship between Social Vulnerability Index and MM trial site availability using logistic regression. RESULTS Between 2002 and 2021, 229 trials were registered across 462 nonunique trial sites in 34 counties. Nearly 50% of trial sites were in academic medical centers, 80% (n = 372) of all trials were industry-sponsored, 60% (n = 274) were early-phase, and 50% (n = 232) were for patients with relapsed or refractory MM. Counties with low as opposed to high poverty rates had six times greater odds of having ≥ 1 MM trial sites (odds ratio [OR], 5.60; 95% CI, 1.85 to 19.64; P = .004). Counties with the lowest percentage of Black Indigenous Persons of Color and non-native English speakers had 77% lower odds (OR, 0.23; 95% CI, 0.07 to 0.69; P = .011) of having ≥ 1 trial sites. The effect remained significant after accounting for the presence of five academic medical centers (n = 95; OR, 0.18; 95% CI, 0.05 to 0.6; P = .008) and adjustment for metropolitan, suburban, or rural status (OR, 0.25; 95% CI, 0.07 to 0.81; P = .025). CONCLUSION Counties with the lowest poverty rates had more MM trial sites, whereas those with the lowest percentage of Black Indigenous Persons of Color populations had fewer MM trial sites. Multilevel efforts are needed to improve the availability and access to trials for socially vulnerable populations.

Abstract
INTRODUCTION Engaging communities in research planning and implementation can enhance recruitment and retention (R&R) of racial and ethnic groups historically excluded and underrepresented in clinical research; however, most studies do not use community-informed approaches. This paper describes the formative research process used to design a Community-Informed Recruitment Plan Template for racial and ethnic groups historically excluded and underrepresented in clinical research. METHODS Using an existing R&R template as a starting point, we iteratively developed and refined the community-informed template through a 3-phase process to achieve cultural-appropriateness. Phase 1 included a literature review, 34 community engagement (CE) studios to review recommendations, community advisory board (CAB) review, and survey data from minority recruitment experts. Phase 2 involved integration of content into existing R&R template. Phase 3 was a final review and revision using input of the CAB and researchers' panel. Survey data collected in Phase 1 were analyzed using descriptives (i.e., frequencies and percentages). Open-ended survey responses were analyzed using inductive, qualitative thematic analysis. RESULTS The final 8-section template can help develop effective grant or proposal language where study R&R plans are requested. They include: 1) Recruitment Strategy; 2) A Stakeholder Communication Plan; 3) Evidence of Recruitment Feasibility; 4) Recruitment and Retention Team; 5) Recruitment and Retention Methods; 6) Recruitment and Retention Timeline; 7) Evaluation; and 8) Budget. CONCLUSIONS Incorporating multiple perspectives into this formative research process enhances the cultural appropriateness of this community-informed R&R template to help research teams achieve R&R goals for individuals historically excluded and underrepresented in clinical research.

Abstract
Importance Since the onset of the COVID-19 pandemic, there have been calls for COVID-19 clinical trials to be fully representative of all demographic groups. However, limited evidence is available about the sex, racial, and ethnic representation among COVID-19 prevention and treatment trials. Objective To investigate whether female participants and racial and ethnic minority individuals are adequately represented in COVID-19 prevention and treatment trials in the US. Data Sources Identified studies were registered on ClinicalTrials.gov or published in the PubMed database from October 2019 to February 2022. Study Selection Included studies must have provided the number of enrolled participants by sex, race, or ethnicity. Only interventional studies conducted in the US for the primary purpose of the diagnosis, prevention, or treatment of (or supportive care for) COVID-19 conditions were included. Data Extraction and Synthesis Data on counts of enrollments by demographic variables (sex, race, and ethnicity) and location (country and state) were abstracted. Studies were broadly categorized by primary purpose as prevention (including vaccine and diagnosis studies) vs treatment (including supportive care studies). A random effects model for single proportions was used. Trial estimates were compared with corresponding estimates of representation in the US population with COVID-19. Main Outcomes and Measures Sex, racial, and ethnic representation in COVID-19 clinical trials compared with their representation in the US population with COVID-19. Results Overall, 122 US-based COVID-19 clinical trials comprising 176 654 participants were analyzed. Studies were predominantly randomized trials (n = 95) for treatment of COVID-19 (n = 103). Sex, race, and ethnicity were reported in 109 (89.3%), 95 (77.9%), and 87 (71.3%) trials, respectively. Estimated representation in prevention and treatment trials vs the US population with COVID-19 was 48.9% and 44.6% vs 52.4% for female participants; 23.0% and 36.6% vs 17.7% for Hispanic or Latino participants; 7.2% and 16.5% vs 14.1% for Black participants; 3.8% and 4.6% vs 3.7% for Asian participants; 0.2% and 0.9% vs 0.2% for Native Hawaiian or Other Pacific Islander participants; and 1.3% and 1.4% vs 1.1% for American Indian or Alaska Native participants. Compared with expected rates in the COVID-19 reference population, female participants were underrepresented in treatment trials (85.1% of expected; P < .001), Black participants (53.7% of expected; P = .003) and Asian participants (64.4% of expected; P = .003) were underrepresented in prevention trials, and Hispanic or Latino participants were overrepresented in treatment trials (206.8% of expected; P < .001). Conclusions and Relevance In this systematic review and meta-analysis, aggregate differences in representation for several demographic groups in COVID-19 prevention and treatment trials in the US were found. Strategies to better ensure diverse representation in COVID-19 studies are needed, especially for prevention trials.

ALZHEIMER'S & DEMENTIA (AMSTERDAM, NETHERLANDS) 2022; 14:e12384. [PMID: 36505397 PMCID: PMC9728547 DOI: 10.1002/dad2.12384] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 07/25/2022] [Revised: 11/04/2022] [Accepted: 11/10/2022] [Indexed: 12/12/2022]
Abstract
Introduction Alzheimer's disease (AD) is a public health priority. AD biomarkers may vary based on race, but the recruitment of diverse participants has been challenging. Methods Three groups of Black and White participants with and without prior research advocacy or participation were interviewed individually or in focus groups to better understand perspectives related to AD biomarker research participation. A rapid qualitative data analytic approach was used to analyze the data. Results Identified barriers to AD biomarker research participation included hesitancy due to fear, distrust of research and researchers, lack of relevant knowledge, and lack of research test results disclosure. Drivers for engagement in biomarker research procedures included knowledge about research, AD, and related clinical procedures, perceived benefits of participation, and outreach from trusted sources. Discussion Participants' comments related to the need for diversity in research and desire for results disclosure suggest opportunities to engage Black individuals. Highlights Black Americans experience more salient barriers to Alzheimer's disease (AD) biomarker research participation.Concerns about research diversity influence research participation decisions.Research test disclosure may affect research participation and retention.

BMC Cancer 2022; 22:983.

Abstract
Background Cancer clinical trials (CCTs) are essential for cancer care, yet the evidence is scarce when it comes to racial disparities in CCT participation among cancer survivors in the Midwest. This study aimed to 1) assess disparities in the awareness of and willingness to participate in CCTs between African American and White cancer survivors; and 2) compare perceptions about CCTs between the two racial groups. Methods The study was based on cross-sectional data from the survey “Minority Patient Participation in Cancer Clinical Trials” that collected information from 147 Black and White cancer survivors from Nebraska between 2015 and 2016. Chi-square tests and logistic regressions were used to assess differences between Black and White cancer survivors regarding their awareness, willingness, and perceptions associated with CCT participation. Results After adjusting for the effects of socio-demographic, health status, and psychosocial variables, Black cancer survivors were much less likely than White cancer survivors to be aware of CCTs (AOR 0.26; CI 0.08–0.81), to express willingness to participate in CCTs (AOR 0.03; CI 0.01, 0.32) and to actually participate in CCTs (AOR 0.13; CI 0.04–0.38). Black cancer survivors reported a lower level of trust in physicians and were less likely than White cancer survivors to believe that CCTs make a significant contribution to science. Conclusions Relative to White cancer survivors, Black cancer survivors had much lower awareness of and willingness to participate in CCTs. Part of these differences might be related to the differential perception of CCTs, psychosocial factors, and trust in physicians between the two groups.

Abstract
BACKGROUND AND OBJECTIVES Increasing evidence suggests patient-oriented benefits of nonoperative management (NOM) for rectal cancer. However, vigilant surveillance requires excellent access to care. We sought to examine patient, socioeconomic, and facility-level factors associated with NOM over time. METHODS Using the National Cancer Database (2006-2017), we examined patients with Stage II-III rectal adenocarcinoma, who received neoadjuvant chemoradiation and received NOM versus surgery. Factors associated with NOM were assessed using multivariable logistic regression with backward stepwise selection. RESULTS There were 59,196 surgical and 8520 NOM patients identified. NOM use increased from 12.9% to 15.9% between 2006 and 2017. Patients who were Black (adjusted odds ratio [aOR]: 1.36, 95% confidence interval [CI]: 1.26-1.47), treated at community cancer centers (aOR: 1.22, 95% CI: 1.12-1.30), without insurance (aOR: 1.87, 95% CI: 1.68-2.09), and with less education (aOR: 1.53, 95% CI: 1.42-1.65) exhibited higher odds of NOM. Patients treated at high-volume centers (aOR: 0.79, 95% CI: 0.74-0.84) and those who traveled >25.6 miles for care (aOR: 0.59, 95% CI: 0.55-0.64) had lower odds of NOM. CONCLUSIONS Vulnerable groups who traditionally have difficulty accessing comprehensive cancer care were more likely to receive NOM, suggesting that healthcare disparities may be driving utilization. More research is needed to understand NOM decision-making in rectal cancer treatment.

The impact of race, ethnicity, and obesity on CAR T-cell therapy outcomes. Blood Adv 2022; 6:6040-6050.

Abstract
Cancer outcomes with chemotherapy are inferior in patients of minority racial/ethnic groups and those with obesity. Chimeric antigen receptor (CAR) T-cell therapy has transformed outcomes for relapsed/refractory hematologic malignancies, but whether its benefits extend commensurately to racial/ethnic minorities and patients with obesity is poorly understood. With a primary focus on patients with B-cell acute lymphoblastic leukemia (B-ALL), we retrospectively evaluated the impact of demographics and obesity on CAR T-cell therapy outcomes in adult and pediatric patients with hematologic malignancies treated with CAR T-cell therapy across 5 phase 1 clinical trials at the National Cancer Institute from 2012 to 2021. Among 139 B-ALL CAR T-cell infusions, 28.8% of patients were Hispanic, 3.6% were Black, and 29.5% were overweight/obese. No significant associations were found between race, ethnicity, or body mass index (BMI) and complete remission rates, neurotoxicity, or overall survival. Hispanic patients were more likely to experience severe cytokine release syndrome compared with White non-Hispanic patients even after adjusting for leukemia disease burden and age (odds ratio, 4.5; P = .001). A descriptive analysis of patients with multiple myeloma (n = 24) and non-Hodgkin lymphoma (n = 23) displayed a similar pattern to the B-ALL cohort. Our findings suggest CAR T-cell therapy may provide substantial benefit across a range of demographics characteristics, including for those populations who are at higher risk for chemotherapy resistance and relapse. However, toxicity profiles may vary. Therefore, efforts to improve access to CAR therapy for underrepresented populations and elucidate mechanisms of differential toxicity among demographic groups should be prioritized.

Abstract
BACKGROUND We describe factors associated with trial enrollment for patients with hepato-pancreato-biliary (HPB) malignancies. We analyzed the association and effect of trial enrollment on overall survival (OS). METHODS The National Cancer Database (2004-2017) was queried for common HPB malignancies (pancreatic adenocarcinoma [PDAC] & neuroendocrine tumors, hepatocellular carcinoma [HCC], biliary tract cancers [BTC]). Multivariable logistic regression was used to identify factors associated with trial enrollment. OS was analyzed by multivariable Cox regression. Inverse-probability-weighted Cox regression was utilized to determine the effect of trial enrollment on OS. RESULTS A total of 1573 (0.3%) of 511,639 patients were enrolled in trials; pancreatic malignancy: 1214 (0.4%); HCC: 217 (0.14%); BTC: 106 (0.15%). HCC and BTC were associated with lower likelihood of enrollment compared with pancreatic malignancy. Black and Hispanic patients were less likely to be enrolled compared to White patients. Treatment at academic facilities and metastatic disease were associated with higher likelihood of enrollment. Enrollment was associated with higher OS for PDAC, metastatic HCC, and metastatic BTC. Trial enrollment exhibited an OS advantage for PDAC and metastatic HCC. CONCLUSION Nationally, fewer than 1% of patients with HPB malignancies were enrolled in clinical trials. There are racial, sociodemographic, and facility-based disparities in trial enrollment.

Abstract
IMPORTANCE The use of chimeric antigen receptor-T cell (CAR-T) therapy and bispecific antibodies in multiple myeloma is expanding, with encouraging early results. It is unknown if the current geographic distribution of CAR-T therapy and bispecific antibodies in multiple myeloma allows access for patients in need, especially for Black populations, which have a higher incidence of multiple myeloma. OBJECTIVE To investigate if the current geographic distribution of CAR-T cell therapy and bispecific antibodies for multiple myeloma allows equitable access for Black patients with multiple myeloma. DESIGN, SETTING, AND PARTICIPANTS This cross-sectional study of data from CAR-T therapy and bispecific antibodies multiple myeloma clinical trials for all available studies listed in ClinicalTrials.gov until January 31, 2022. Only studies with 1 or more open sites in the US were analyzed. Data were analyzed February 2022. RESULTS A total of 162 clinical trials were found, and 69 analyzed-7896 participants were either enrolled or expected to enroll, with 4386 participants (55.5%) enrolled or to be enrolled in CAR-T therapies clinical trials. The vast majority of clinical trials (66 [96%]) were sponsored by industry, and there were 140 clinical trials sites. The mean number of sites per trial was 8.1 (7.8 for CAR-T trials [range, 1-30 trials] vs 8.7 for bispecific antibodies [range, 1-26 trials]). Only 35.9% of Black patients lived in a county with an open trial. For the 10 states with the highest proportion of Black residents (ranging from 18.6% to 41.4%), 6 of those states (60%) had no (3 states) or less than 3 clinical trial openings (3 states) for either a CAR-T or bispecific antibody study. CONCLUSIONS AND RELEVANCE In this cross-sectional study, we found that the geographic distribution of clinical trials for CAR-T and bispecific antibodies may contribute to disparities in access to the most advanced clinical trials for new multiple myeloma therapies. Since most of the ongoing trials were sponsored by industry, regulating the distribution of clinical trial sites may reduce these inequities.

Abstract
To address health disparities faced by Black patients with cancer, it is critical that researchers conducting cancer clinical trials (CCTs) equitably recruit and retain Black participants, develop strategies toward this aim, and document associated outcomes. This narrative scoping literature review, as part of a larger study, aimed to identify, describe, and categorize strategies and interventions intended to improve the recruitment and retention of Black participants with breast, lung, prostate, colorectal, or multiple myeloma cancer into CCTs. We conducted comprehensive searches in PubMed, Embase, Cochrane Library, PsycInfo, CINAHL, Scopus, and Web of Science with three main concepts: Black persons, neoplasms, and clinical trial recruitment. The search resulted in 1,506 articles, of which 15 met inclusion criteria. Five main categories of recruitment and retention strategies and interventions were identified based on their specific population focus and type of approach: (1) participant identification, (2) provider awareness/resources, (3) focused research staff interventions, (4) patient and community–focused awareness strategies, and (5) participant-directed resources. Thirteen studies had recruitment acceptance rates of over 30%. Eight studies with acceptance rates of ≥ 50% reported implementing ≥ 5 strategies, with an average use of seven strategies across multiple categories. Five studies with acceptance rates ≥ 50% implemented strategies in ≥ 3 categories. Four studies reported retention rates ≥ 74%. Three studies with reported retention rates ≥ 74% used strategies in ≥ 3 categories, and all included strategies aimed at meeting participant needs beyond the study. Our results show that many efforts that aim to increase the recruitment and retention of Black participants into CCTs have great potential, but the most promising strategies use a multiprong approach.

Abstract
Diverse factors contribute to significant and dire disparities in cancer risk and treatment outcomes. To address this, there was a call for inclusion of sex as a biological variable, which resulted in more instances of careful inclusion of sex in preclinical studies of cancer. Another variable in cancer treatment is genetic ancestry. Although this is considered explicitly in clinical research, it is considerably neglected in preclinical studies. Preclinical research can use several 3D in vitro model systems, such as spheroids/organoids, xenografts, or other bioengineered systems that combine biomaterials and cellular material. Ultimately, the cellular base for all of these in vitro model systems is derived from human cell lines or patient samples, to investigate mechanisms of cancer and screen novel therapeutics, all of which aim to maximize successful outcomes in clinical trials. This in itself offers an opportunity to potentiate effective treatments for many groups of people, when diverse variables like genetic ancestry are consciously included into study design. This Perspective highlights the need for conscious inclusion of genetic ancestry in preclinical cancer tissue engineering, especially when it pertains to determining therapeutic outcomes. Summary: Genetic determinants, like ancestry, impact cancer risk and therapeutic outcomes. Hence, this is an important variable to consider at the very initial stages of biomedical research at the bench.

Abstract
IMPORTANCE Disparities that affect Black persons with various hematological malignant neoplasms are substantial, yet little is known about disparities related to the use of US Food and Drug Administration (FDA)-approved chimeric antigen receptor-T cell (CAR-T) therapy. OBJECTIVE To examine the enrollment of Black participants in clinical trials that resulted in a subsequent FDA approval of CAR-T products in hematological malignant neoplasms. DESIGN, SETTING, AND PARTICIPANTS A cross-sectional study was performed using publicly available data on drug products and demographic subgroups from Drugs@fda in the period of August 2017 to May 2021. Data analysis included patients with large B cell lymphoma, follicular lymphoma, mantle cell lymphoma, acute lymphoblastic leukemia, and multiple myeloma who were enrolled into 7 clinical trials that investigated various CAR-T products. The study was conducted from July 1, 2021, to November 30, 2021. MAIN OUTCOMES AND MEASURES Frequencies of participation of Black participants were calculated with adjustment for disease prevalence. RESULTS Of the 1057 enrolled patients included in the study, CAR-T products were given to 746 patients (71%), and efficacy was reported for 729 enrolled patients (69%) across all the approved CAR-T products and indications. Most patients (1015 patients [96%]) were enrolled in the US. Black participants were included in the racial category other in the study that supported tisagenlecleucel approval in acute lymphoblastic leukemia; otherwise, their enrollment was specified either in the study publication and/or the demographic subgroup information available under the FDA product labeling information. The number of Black participants who received the CAR-T product and had reported efficacy varied between studies (range, 1-12 participants [2%-5%]). Adjusted prevalence measures showed the lowest participation to prevalence ratio of 0.2 for multiple myeloma and 0.6 for large B cell lymphoma. CONCLUSIONS AND RELEVANCE The findings of this study suggest that there are substantial disparities affecting Black patients across all approved CAR-T products used to treat hematological malignant neoplasms with otherwise limited effective treatment options. The study findings might aid policy discussions regarding the immediate need of regulations that enforce certain thresholds of Black patients' enrollment before granting FDA approval.

Abstract
The population of older adults with cancer in the United States is rapidly increasing, which will have a substantial impact on the oncology and public health workforces across the cancer continuum, from prevention to end of life. Unfortunately, inequities in existing social structures that cause increased psychosocial stressors have led to disparities in the incidence of cancer and the morbidity and mortality of cancer for individuals from marginalized backgrounds. It is imperative that older adults, especially those from historically marginalized backgrounds, be adequately represented in all stages of cancer research to address health inequities. Continued efforts and progress toward achieving social justice and health equity require a deeper commitment to and better understanding of the impact of social determinants of health within the cancer domain. Undoubtedly, a more holistic and integrated view that extends beyond the biologic and genetic factors of health must be adopted for health entities to recognize the critical role of environmental, behavioral, and social determinants in cancer health disparities. Against this backdrop, this paper uses a life course approach to present a multifactorial framework for understanding and addressing cancer disparities in an effort to advance social justice and health equity for racially and ethnically diverse older adults.
