Achieving Cancer Equity by Improving Health Insurance Access for All Latinos.

Cancer is the top leading cause of death among Latino people. Lack of health insurance is a significant contributor to inadequate cancer detection and treatment. Despite healthcare policy expansions such as the Affordable Care Act, Latino people persistently maintain the highest uninsured rate among any ethnic and racial group in the US, especially among Latino individuals who are immigrants or part of a mixed immigration status household. Recognizing that immigration status is a critical factor in the ability of Latino community members to seek health insurance and access healthcare services, a few US states and the District of Columbia have implemented policies that have expanded coverage to children and adults regardless of immigration status. Expansion of Medicaid eligibility regardless of immigration status may significantly benefit Latino communities, however the facilitators and barriers to enrolling in these programs need to be evaluated to ensure reach and achieve health equity across the cancer control continuum for all Latinos.

Trends in 5-year cancer survival disparities by race and ethnicity in the US between 2002-2006 and 2015-2019.

Racial and ethnic disparities persist in cancer survival rates across the United States, despite overall improvements. This comprehensive analysis examines trends in 5-year relative survival rates from 2002-2006 to 2015-2019 for major cancer types, elucidating differences among racial/ethnic groups to guide equitable healthcare strategies. Data from the SEER Program spanning 2000-2020 were analyzed, focusing on breast, colorectal, prostate, lung, pancreatic cancers, non-Hodgkin lymphoma, acute leukemia, and multiple myeloma. Age-standardized relative survival rates were calculated to assess racial (White, Black, American Indian/Alaska Native, Asian/Pacific Islander) and ethnic (Hispanic, Non-Hispanic) disparities, utilizing period analysis for recent estimates and excluding cases identified solely through autopsy or death certificates. While significant survival improvements were observed for most cancers, notable disparities persisted. Non-Hispanic Blacks exhibited the largest gain in breast cancer survival, with an increase of 5.2% points (from 77.6 to 82.8%); however, the survival rate remained lower than that of Non-Hispanic Whites (92.1%). Colorectal cancer survival declined overall (64.7-64.1%), marked by a 6.2% point drop for Non-Hispanic American Indian/Alaska Natives (66.3-60.1%). Prostate cancer survival declined across all races, with Non-Hispanic American Indian/Alaska Natives showing a decrease of 7.7% points (from 96.9 to 89.2%). Lung cancer, acute leukemia, and multiple myeloma showed notable increases across groups. Substantial racial/ethnic disparities in cancer survival underscore the notable need for tailored strategies ensuring equitable access to advanced treatments, particularly addressing significant trends in colorectal and pancreatic cancers among specific minority groups. Careful interpretation of statistical significance is warranted given the large dataset.

Exploring Racial Disparities in Awareness and Perceptions of Oncology Clinical Trials: Cross-Sectional Analysis of Baseline Data From the mychoice Study.

BACKGROUND: Black/African American adults are underrepresented in oncology clinical trials in the United States, despite efforts at narrowing this disparity. OBJECTIVE: This study aims to explore differences in how Black/African American oncology patients perceive clinical trials to improve support for the clinical trial participation decision-making process. METHODS: As part of a larger randomized controlled trial, a total of 244 adult oncology patients receiving active treatment or follow-up care completed a cross-sectional baseline survey on sociodemographic characteristics, clinical trial knowledge, health literacy, perceptions of cancer clinical trials, patient activation, patient advocacy, health care self-efficacy, decisional conflict, and clinical trial intentions. Self-reported race was dichotomized into Black/African American and non-Black/African American. As appropriate, 2-tailed t tests and chi-square tests of independence were used to examine differences between groups. RESULTS: Black/African American participants had lower clinical trial knowledge (P=.006), lower health literacy (P<.001), and more medical mistrust (all P values <.05) than non-Black/African American participants. While intentions to participate in a clinical trial, if offered, did not vary between Black/African American and non-Black/African American participants, Black/African American participants indicated lower awareness of clinical trials, fewer benefits of clinical trials, and more uncertainty around clinical trial decision-making (all P values <.05). There were no differences for other variables. CONCLUSIONS: Despite no significant differences in intent to participate in a clinical trial if offered and high overall trust in individual health care providers among both groups, beliefs persist about barriers to and benefits of clinical trial participation among Black/African American patients. Findings highlight specific ways that education and resources about clinical trials could be tailored to better suit the informational and decision-making needs and preferences of Black/African American oncology patients.

An elevated rate of whole-genome duplications in cancers from Black patients.

In the United States, Black individuals have higher rates of cancer mortality than any other racial group. Here, we examine chromosome copy number changes in cancers from more than 1800 self-reported Black patients. We find that tumors from self-reported Black patients are significantly more likely to exhibit whole-genome duplications (WGDs), a genomic event that enhances metastasis and aggressive disease, compared to tumors from self-reported white patients. This increase in WGD frequency is observed across multiple cancer types, including breast, endometrial, and lung cancer, and is associated with shorter patient survival. We further demonstrate that combustion byproducts are capable of inducing WGDs in cell culture, and cancers from self-reported Black patients exhibit mutational signatures consistent with exposure to these carcinogens. In total, these findings identify a type of genomic alteration that is associated with environmental exposures and that may influence racial disparities in cancer outcomes.

The COVID-19 pandemic and associated declines in cancer incidence by race/ethnicity and census-tract level SES, rurality, and persistent poverty status.

BACKGROUND: The COVID-19 pandemic had a significant impact on cancer screening and treatment, particularly in 2020. However, no single study has comprehensively analyzed its effects on cancer incidence and disparities among groups such as race/ethnicity, socioeconomic status (SES), persistent poverty (PP), and rurality. METHODS: Utilizing the recent data from the United States National Cancer Institute's Surveillance, Epidemiology, and End Results Program, we calculated delay- and age-adjusted incidence rates for 13 cancer sites in 2020 and 2015-2019. Percent changes (PCs) of rates in 2020 compared to 2015-2019 were measured and compared across race/ethnic, census tract-level SES, PP, and rurality groups. RESULTS: Overall, incidence rates decreased from 2015-2019 to 2020, with varying PCs by cancer sites and population groups. Notably, NH Blacks showed significantly larger PCs than NH Whites in female lung, prostate, and colon cancers (e.g., prostate cancer: NH Blacks -7.3, 95% CI: [-9.0, -5.5]; NH Whites: -3.1, 95% CI: [-3.9, -2.2]). Significantly larger PCs were observed for the lowest versus highest SES groups (prostate cancer), PP versus non-PP groups (prostate and female breast cancer), and all urban versus rural areas (prostate, female breast, female and male lung, colon, cervix, melanoma, liver, bladder, and kidney cancer). CONCLUSIONS: The COVID-19 pandemic coincided with reduction in incidence rates in the U.S. in 2020 and was associated with worsening disparities among groups, including race/ethnicity, SES, rurality, and PP groups, across most cancer sites. Further investigation is needed to understand the specific effects of COVID-19 on different population groups of interest.

Racial and ethnic disparities in mortality among World Trade Center Health Registry enrollees with post-9/11 cancer.

INTRODUCTION: There are well-documented racial and ethnic disparities in mortality after cancer in the general population, but less is known about whether disparities also exist in disaster-exposed populations. METHODS: We conducted a longitudinal cohort study of 4341 enrollees in the World Trade Center Health Registry (WTCHR) with a first-ever primary invasive cancer diagnosis after 9/11/2001 and followed through 2020. We examined associations of race and ethnicity with all-cause mortality risk and cause-specific mortality risk using multivariable Cox proportional hazards regression models and Fine and Gray's proportional sub-distribution hazards models, respectively. Models were adjusted for baseline characteristics and tumor characteristics. We also examined models further adjusted for socioeconomic status (SES), and we used inverse odds weighting to formally test for mediation by SES. RESULTS: Compared to non-Hispanic White enrollees with cancer, non-Hispanic Blacks had higher risks for all-cause mortality (adjusted hazard ratio (aHR) = 1.20, 95% CI = 1.02-1.41) and non-cancer mortality (aHR = 1.48, 95% CI = 1.09-2.01) in the full model. In the model without SES, Hispanic enrollees with cancer had higher risks for all-cause mortality (aHR = 1.32, 95% CI = 1.09-1.60) and cancer mortality (aHR = 1.31, 95% CI = 1.05-1.64) compared to non-Hispanic Whites; these associations became not statistically significant in the full model. In the inverse odds weighting analysis, SES explained 24% and 29% of the disparity in all-cause mortality risk observed in non-Hispanic Blacks and Hispanics, respectively, compared to non-Hispanic Whites. CONCLUSION: This study found that there are racial and ethnic disparities in mortality after cancer in the WTCHR. Additional studies are needed to further explore the factors mediating these disparities.

Medical student clinical cultural awareness in cancer care of sexual gender minority patients.

OBJECTIVE: Health disparities in lesbian, gay, bisexual, transgender, and queer/questioning (LGBTQ+), or sexual and gender minority (SGM) people are known. SGM people have higher cancer risk, but lower rates of screenings, resulting in a higher likelihood of late-stage disease. This study evaluates medical students' clinical cultural awareness in cancer care of SGM patients to identify gaps in education. METHODS: This was a cross-sectional survey distributed to medical students at a academic center. There were 38 questions on demographics, attitudes, and knowledge of SGM topics. Descriptive statistics were used for demographic information and stratified analyses assessed responses by demographic subgroups. RESULTS: There were 238 responses from 1145 students (response rate = 20.7 %). Of the responders, 91.2 % and 79 % were comfortable treating lesbian, gay, bisexual (LGB) and transgender patients respectively. Only 28.6 % and 21.8 % were confident treating LGB and transgender patients respectively after taking the survey. 91.2 % of students were interested receiving education regarding SGM health needs. CONCLUSION: While most medical students are comfortable treating LGBTQ+ patients, most are not confident in their knowledge. This difference is most profound in knowledge of transgender patients. PRACTICE IMPLICATIONS: Schools must provide more education in SGM topics to improve student knowledge to produce competent providers.

Early-onset cancer incidence in the United States by race/ethnicity between 2011 and 2020.

We characterized trends in early onset (aged 20-49) cancer incidence by race/ethnicity and sex using the 2011-2020 Surveillance, Epidemiology, and End Results (SEER) Program dataset. We estimated age-standardized cancer incidence rates, incidence rate ratios (IRR), and annual percentage changes (APC) with 95 % confidence intervals (CI). During the time period examined, cancer incidence increased for female breast (APC: 0.64; 95 % CI: 0.10, 1.20), female colorectal (APC: 2.16; 95 % CI: 1.22, 3.10), and male colorectal (APC: 2.49; 95 % CI: 1.81, 3.19) cancer. Among racial/ethnic groups examined, Hispanic individuals had the largest increases in female all sites (APC: 1.31; 95 % CI: 0.38, 2.25), female breast (APC: 1.04; 95 % CI: 0.29, 1.81), and female (APC: 4.67; 95 % Cl: 3.07, 6.30) and male (APC: 3.53; 95 % CI: 2.58, 4.49) colorectal cancer incidence. Further research is needed to clarify the causal mechanisms driving these patterns.

Addressing the Health Needs of Indian Americans in the Greater Philadelphia Region Through a Scoping Survey: Cancer Screening Assessment.

Despite higher income and education, there are profound health disparities among Asian Americans. These disparities are highlighted in particular by screening behaviors for cancer. Between 1998 and 2008, cancer rates increased threefold among Indian Americans, raising concern that cancer screening in this group may be especially low. To better understand cancer screening behavior, we collected data from a total of 157 self-identifying Indian Americans residing in the greater Philadelphia area. Nearly all participants reported having health insurance (98.7%), and most had received a physical exam within a year (87.3%). Only17.4% of the participants were referred for mammography, while 30% of participants over age 30 were referred for ovarian cancer screening. Just 4 participants were recommended for pancreatic cancer screening. The findings contribute new information to the understanding of health needs of Indian Americans residing in the greater Philadelphia region and reveal a need for greater focus on preventive care.

Multidimensional structural racism and estimated cancer risk from traffic-related air pollution.

BACKGROUND: Traffic-related air pollutants have been associated with a variety of adverse human health impacts, including cancers. In the United States, numerous studies have documented racial inequities in neighborhood exposures to traffic-related air pollution. Emerging evidence suggests that structural racism may influence neighborhood exposures to air pollutants. However, existing research has largely focused on residential racial segregation, one indicator of structural racism. This study developed a multidimensional measure of structural racism to examine the relationship between structural racism and estimated cancer risk from air pollutants in Georgia. METHODS: Carcinogenic air toxics data were obtained from the US Environmental Protection Agency's 2019 Air Toxics Screening Assessment and sociodemographic data from the American Community Survey. Guided by stakeholder input, county-level data on residential segregation, education, employment, incarceration, economic status, political participation, and homeownership were used to create a multidimensional county-level structural racism index. Relative risks (RRs) were estimated for associations between structural racism and elevated (top 10% in Georgia) estimated cancer risk from air toxics. RESULTS: Multilevel analyses revealed a significant association between multidimensional structural racism and exposure to carcinogenic traffic-related air pollutants. Neighborhoods in the highest quartile of structural racism exhibited an elevated cancer risk from traffic-related air pollutants (RR, 7.84; 95% CI, 5.11-12.05) compared to neighborhoods with lower levels of structural racism. CONCLUSIONS: Multidimensional structural racism was associated with estimated cancer risk from traffic-related air pollution in Georgia. Findings can inform future studies and policy interventions that address racial inequalities in exposure to traffic-related air pollution.

Associations between Structural Racism, Environmental Burden, and Cancer Rates: An Ecological Study of US Counties.

Objective: In this study, we examined associations between county-level measures of structural racism and county-level cancer incidence and mortality rates between race groups while accounting for factors associated with cancer rates and county-level measures of environmental burden. Methods: To explore this relationship, we conducted multiple linear regression analyses. Data for these analyses came from an index of county-level structural racism and publicly available data on 2015 to 2019 age-adjusted cancer rates from the US Cancer Statistics Data Visualization Tool, 2019 County Health Rankings and Roadmaps, the Environmental Protection Agency's 2006 to 2010 Environmental Quality Index, and 2015 to 2019 estimates from the US Census American Community Survey. Results: County-level structural racism was associated with higher county cancer incidence rates among Black (adjusted incidence rate: 17.4, 95% confidence interval [95% CI]: 9.3, 25.5) and Asian/Pacific Islander populations (adjusted incidence rate: 9.3, 95% CI: 1.8, 16.9) and higher mortality rates for American Indian/Alaskan Native (adjusted mortality rate [AMR]: 17.4, 95% CI: 4.2, 30.6), Black (AMR: 11.9, 95% CI: 8.9, 14.8), and Asian/Pacific Islander (AMR: 4.7, 95% CI: 1.3, 8.1) populations than White populations. Conclusion: Our findings highlight the detrimental impact of structural racism on cancer outcomes among minoritized populations. Strategies aiming to mitigate cancer disparities must embed processes to recognize and address systems, policies, laws, and norms that create and reproduce patterns of discrimination.

Understanding Indigenous peoples experiences to inform recommendations for improving cultural safety and care in radiation therapy centres in Alberta, Canada.

INTRODUCTION: Rates of common cancers are continuously increasing among Indigenous peoples and are above the incidence rates of non-Indigenous Canadians. When considering the intersecting social determinants of health such as culture, geography, funding, and access to basic health services, these all contribute to the unique cancer burden faced by Indigenous people. Indigenous patients sometimes feel alienated by the word "cancer", intimidated in the oncology setting and often avoid or delay seeking care, bypass screening and preventative care, and cease prescribed treatment before it is finished. Providing culturally competent, safe care to improve Indigenous health outcomes have been suggested and prioritized in health care systems across Canada. METHODS: Using an Indigenous methodology, sharing circles were held in Northern Alberta, Canada. Five Indigenous survivors of cancer and two Indigenous caregivers shared their experiences with oncology treatment in the radiation therapy centre. Results were transcribed verbatim and thematic analysis was conducted. RESULTS: This resulted in four main themes (1) historical and cultural understandings (2) reduce systemic harm by having dedicated Indigenous staff, cultural competency, and Indigenous specific supports (3) meaningful time commitment and relationship building (4) importance of kinship and Indigenous-centred, family-and-patient-centred care. These themes fed into the development of nine recommendations for policy and decision makers to improve cultural safety in the Alberta radiation therapy centres. CONCLUSION: Support for Indigenous patients and caregivers is essential to improve care in the radiation therapy centres. The findings from this work will support recommendations for health decision and policy makers within radiation therapy centres, which may be transferable to other centres within oncology and health.

Structural Racism and Obesity-Related Cancer Inequities in the United States: Challenges and Research Priorities.

Structural racism has been identified as a fundamental cause of health disparities. For example, racial, ethnic, and economic neighborhood segregation; concentrated poverty; community disinvestment; and sociocultural context influence obesity and cancer disparities. Effects of structural racism are also evident through neighborhood obesogenic conditions such as limited access to affordable and healthy foods and physical activity opportunities within segregated communities that contribute to obesity and obesity-related cancer disparities. This article describes and expands on cross-cutting themes raised during a webinar held by the National Cancer Institute (NCI): (1) how structural factors, including neighborhood segregation and obesogenic conditions within racial and ethnic disadvantaged communities, influence disparities in the United States; (2) current research challenges and best ways to address them; and (3) selected priorities of the NCI aimed at addressing multilevel and intersecting factors that influence obesity-related cancer disparities. Further research is needed to understand how residential segregation and neighborhood obesogenic conditions influence cancer prevention and control across the continuum. Identifying the best approaches to address obesity and cancer disparities using social determinants of health framework and community-engaged approaches guided by a structural racism lens will allow researchers to move beyond individual-level approaches.

Racial differences in treatment adherence and response to acupuncture and cognitive behavioral therapy for insomnia among Black and White cancer survivors.

BACKGROUND: Racial disparities in sleep are well-documented. However, evidence-based options for addressing these disparities are lacking in cancer populations. To inform future research on sleep interventions, this study aims to understand racial differences in treatment responses to acupuncture and cognitive behavioral therapy for insomnia (CBT-I) among Black and White cancer survivors. METHODS: We conducted a secondary analysis of a comparative effectiveness trial evaluating acupuncture versus CBT-I for insomnia in cancer survivors. We compared insomnia severity, sleep characteristics, and co-morbid symptoms, as well as treatment attitudes, adherence, and responses among Black and White participants. RESULTS: Among 156 cancer survivors (28% Black), Black survivors reported poorer sleep quality, longer sleep onset latency, and higher pain at baseline, compared to White survivors (all p < 0.05). Black survivors demonstrated lower adherence to CBT-I than White survivors (61.5% vs. 88.5%, p = 0.006), but their treatment response to CBT-I was similar to white survivors. Black survivors had similar adherence to acupuncture as white survivors (82.3% vs. 93.4%, p = 0.16), but they had greater reduction in insomnia severity with acupuncture (-3.0 points, 95% CI -5.4 to 0.4, p = 0.02). CONCLUSION: This study identified racial differences in sleep characteristics, as well as treatment adherence and responses to CBT-I and acupuncture. To address racial disparities in sleep health, future research should focus on improving CBT-I adherence and confirming the effectiveness of acupuncture in Black cancer survivors.

Racial Disparities in Cancer Stage at Diagnosis and Survival for Adolescents and Young Adults.

Importance: There are limited studies assessing stage at diagnosis and risk of death among all 5 federally defined races in the US among adolescent and young adult (AYA) patients with cancer. Objective: To identify racial disparities in stage at diagnosis and survival among AYA patients with cancer. Design, Setting, and Participants: This retrospective cohort study used data from a US national hospital-based oncology database on AYA patients, aged 15 to 39 years, with the 10 deadliest cancers among AYA patients who received a diagnosis from January 1, 2004, to December 31, 2017, with 6 months or more of follow-up. Analyses by race were categorized by the 5 federally defined races in the US: American Indian or Alaska Native, Asian, Black, Native Hawaiian or Other Pacific Islander, and non-Hispanic White (hereafter, White). White patients served as the majority reference group. Statistical analysis was performed from November 2022 to September 2023. Main Outcomes and Measures: The primary end points were late stage at diagnosis (logistic regression with adjusted odds ratios [AORs] and 95% CIs) and overall survival (log-rank tests and Cox proportional hazards regression with adjusted hazard ratios [AHRs] and 95% CIs). Results: A total of 291 899 AYA patients (median age, 33 years [IQR, 28-37 years]; 186 549 female patients [64%]; 189 812 [65%] with stage I or II cancers) were evaluated. The cohort included 1457 American Indian or Alaska Native patients (1%), 8412 Asian patients (3%), 40 851 Black patients (14%), 987 Native Hawaiian or Other Pacific Islander patients (0.3%), and 240 192 White patients (82%). Cancers included breast (n = 79 195 [27%]), lymphoma (n = 45 500 [16%]), melanoma (n = 36 724 [13%]), testis (n = 31 413 [11%]), central nervous system (n = 26 070 [9%]), colon or rectum (n = 22 545 [8%]), cervix (n = 20 923 [7%]), sarcoma (n = 14 951 [5%]), ovary (n = 8982 [3%]), and lung (n = 5596 [2%]). Risk of late-stage diagnosis was higher for Asian (AOR, 1.20; 95% CI, 1.14-1.26), Black (AOR, 1.40; 95% CI, 1.36-1.43), and Native Hawaiian or Other Pacific Islander (AOR, 1.34; 95% CI, 1.16-1.55) patients compared with White patients. Overall survival differed by race for all cancer sites, except cancers of the central nervous system and ovary. Risk of death was higher for American Indian or Alaska Native (AHR, 1.15; 95% CI, 1.02-1.30), Black (AHR, 1.22; 95% CI, 1.19-1.26), and Native Hawaiian or Other Pacific Islander (AHR, 1.25; 95% CI, 1.09-1.44) patients but lower for Asian patients (AHR, 0.90; 95% CI, 0.85-0.95) compared with White patients. Conclusions and Relevance: This cohort study of AYA patients suggests that stage at diagnosis and survival varied across races for the 10 deadliest AYA cancers. These results support the need for tailored interventions and informed public policy to achieve cancer care equity for all races.

Creating safer cancer care with ethnic minority patients: A qualitative analysis of the experiences of cancer service staff.

INTRODUCTION: Effective consumer engagement practices can enhance patient safety. This is important for consumers from ethnic minority backgrounds who are exposed to increased risk of patient safety events. Using the Systems Engineering Initiative for Patient Safety model, this study explored staff experiences of creating opportunities for engagement with consumers from ethnic minority backgrounds to contribute to their cancer care safety. METHOD: A qualitative study was conducted using semistructured interviews with cancer service staff from four cancer services across two states in Australia. Purposive sampling was used to recruit healthcare staff from a diverse range of professions. Data were analysed using the Framework Analysis method. RESULTS: Fifty-four interviews were conducted with healthcare staff. Analysis of the qualitative interview data identified enablers and associated challenges that contributed to creating a shared understanding between consumers and staff of the information, processes, expectations and problems arising in care. Enablers and challenges are reported in relation to four themes: (1) co-creating safety through shared understanding of care processes; (2) tools and technologies support planned communication; (3) organisational policy levers exist but lack implementation in direct care and (4) formal tasks incorporate consumer engagement more readily than informal interactions. CONCLUSION: The availability of infrastructure and resources to support communication with consumers from ethnic minority backgrounds was limited to specific tasks across the cancer care continuum. Strategies implemented by health services to foster effective communication during formal interactions now require expansion to support and create conditions for effective consumer engagement during informal and everyday care tasks. The use of innovative language support tools and cultural considerations are required at the service and system level to support consumer engagement in all types of care interactions. PUBLIC AND PATIENT INVOLVEMENT: The study was embedded within a larger project that included a consumer investigator and was guided by a consumer advisory group (CAG). These consumer team members have lived experience of cancer and are from diverse ethnic backgrounds. CAG members provided feedback on the draft interview guide and participant information for this study.

Differences in the mutational landscape of clonal hematopoiesis of indeterminate potential among races and between male and female patients with cancer.

Clonal hematopoiesis of indeterminate potential (CHIP) has emerged as a significant precursor to hematological malignancies and is associated with several age-related diseases. We leveraged public data to explore differences in the mutational landscape of CHIP between males (Ms) and females (Fs) and across diverse racial populations. DNA (cytosine-5) methyltransferase 3 alpha (DNMT3A) mutations were substantially more prevalent in Fs than in Ms (38.94% vs. 31.37%, p-value: < 0.001, q-value: < 0.001). Additional sex combs-like 1 (ASXL1) mutations were more frequent in Ms than Fs (5.82% vs. 2.69%, p-value < 0.001, q-value < 0.001). In the racial cohorts with sufficient sample sizes, STAT5B and CSF1R mutations were most frequent in Asian populations (1.40% and 0.84%), followed by Black populations (0.98% and 0.24%) and White populations (0.29% and 0.09%) (p-value: < 0.001 , q-value: 0.023 for both genes). Several other CHIP mutations were enriched in Black: RARA, SMAD2, CDKN1B, CENPA, CTLA4, EIF1AX, ELF3, MSI1, MYC, SOX17, and AURKA. On the other hand, H3C1, H3C4, and MYCL were enriched in the Asian cohort. Our analysis highlights sex and racial differences in CHIP mutations among patients with cancer. As CHIP continues to gain recognition as a critical precursor to malignancies and other diseases, understanding how these differences contribute to CHIP's underlying mechanisms and clinical implications is critical.

Association between Hispanic Ethnicity and Greater Expectation of Benefit from Acupuncture or Massage for Pain in Cancer.

Individuals living with cancer and survivors of cancer who self-identify as Hispanic experience higher pain burden and greater barriers to pain management compared with their non-Hispanic counterparts. The Society for Integrative Oncology-ASCO guideline recommends acupuncture and massage for cancer pain management. However, Hispanic individuals' expectations about these modalities remain under-studied and highlight a potential barrier to treatment utilization in this population. We conducted a subgroup analysis of baseline data from two randomized clinical trials to evaluate ethnic differences in treatment expectations about integrative pain treatment modalities among Hispanic and non-Hispanic cancer patients and survivors of cancer. The Mao Expectancy of Treatment Effects (METE) instrument was used to measure treatment expectancy for electro-acupuncture, auricular acupuncture, and massage therapy. Results of this study demonstrated that Hispanic participants reported greater expectation of benefit from electroacupuncture, auricular acupuncture, and massage (all P < 0.01). After controlling for age, gender, race, and education, Hispanic ethnicity remained significantly associated with greater expectation of benefit from integrative therapies for pain (coef.=1.47, 95% CI, 0.67-2.27). Non-white race (coef.=1.04, 95% CI, 0.42-1.65), no college education (coef.=1.16, 95% CI, 0.59-1.74), and female gender (coef.=0.94, 95% CI, 0.38-1.50) were also associated with a greater expectation of benefit from integrative therapies. Pain management should be informed by a shared decision-making approach that aligns treatment expectancy with treatment selections to optimize outcomes. Compared with non-Hispanic participants, Hispanic individuals reported higher expectation of benefit from acupuncture and massage, highlighting the potential role for integrative therapies in addressing ethnic pain disparities. Trial Registration NCT02979574 NCT04095234.

Race and Ethnicity, Socioeconomic Factors, and Epigenetic Age Acceleration in Survivors of Childhood Cancer.

Importance: Current research in epigenetic age acceleration (EAA) is limited to non-Hispanic White individuals. It is imperative to improve inclusivity by considering racial and ethnic minorities in EAA research. Objective: To compare non-Hispanic Black with non-Hispanic White survivors of childhood cancer by examining the associations of EAA with cancer treatment exposures, potential racial and ethnic disparity in EAA, and mediating roles of social determinants of health (SDOH). Design, Setting, and Participants: In this cross-sectional study, participants were from the St Jude Lifetime Cohort, which was initiated in 2007 with ongoing follow-up. Eligible participants included non-Hispanic Black and non-Hispanic White survivors of childhood cancer treated at St Jude Children's Research Hospital between 1962 and 2012 who had DNA methylation data. Data analysis was conducted from February 2023 to May 2024. Exposure: Three treatment exposures for childhood cancer (chest radiotherapy, alkylating agents, and epipodophyllotoxin). Main Outcomes and Measures: DNA methylation was generated from peripheral blood mononuclear cell-derived DNA. EAA was calculated as residuals from regressing Levine or Horvath epigenetic age on chronological age. SDOH included educational attainment, annual personal income, and the socioeconomic area deprivation index (ADI). General linear models evaluated cross-sectional associations of EAA with race and ethnicity (non-Hispanic Black and non-Hispanic White) and/or SDOH, adjusting for sex, body mass index, smoking, and cancer treatments. Adjusted least square means (ALSM) of EAA were calculated for group comparisons. Mediation analysis treated SDOH as mediators with average causal mediation effect (ACME) calculated for the association of EAA with race and ethnicity. Results: Among a total of 1706 survivors including 230 non-Hispanic Black survivors (median [IQR] age at diagnosis, 9.5 [4.3-14.3] years; 103 male [44.8%] and 127 female [55.2%]) and 1476 non-Hispanic White survivors (median [IQR] age at diagnosis, 9.3 [3.9-14.6] years; 766 male [51.9%] and 710 female [48.1%]), EAA was significantly greater among non-Hispanic Black survivors (ALSM = 1.41; 95% CI, 0.66 to 2.16) than non-Hispanic White survivors (ALSM = 0.47; 95% CI, 0.12 to 0.81). Among non-Hispanic Black survivors, EAA was significantly increased among those exposed to chest radiotherapy (ALSM = 2.82; 95% CI, 1.37 to 4.26) vs those unexposed (ALSM = 0.46; 95% CI, -0.60 to 1.51), among those exposed to alkylating agents (ALSM = 2.33; 95% CI, 1.21 to 3.45) vs those unexposed (ALSM = 0.95; 95% CI, -0.38 to 2.27), and among those exposed to epipodophyllotoxins (ALSM = 2.83; 95% CI, 1.27 to 4.40) vs those unexposed (ALSM = 0.44; 95% CI, -0.52 to 1.40). The association of EAA with epipodophyllotoxins differed by race and ethnicity (ß for non-Hispanic Black survivors, 2.39 years; 95% CI, 0.74 to 4.04 years; ß for non-Hispanic White survivors, 0.68; 95% CI, 0.05 to 1.31 years) and the difference was significant (1.77 years; 95% CI, 0.01 to 3.53 years; P for interaction = .049). Racial and ethnic disparities in EAA were mediated by educational attainment (
