A Randomized Controlled Trial of Gamification to Increase Physical Activity Among Black and Hispanic Breast and Prostate Cancer Survivors: Rationale and Design of the ALLSTAR Clinical Trial

Survivors of breast and prostate cancer, especially those that are Black and/or Hispanic, are at high risk for cardiovascular events. Physical activity can reduce the risk of cardiovascular events in cancer survivors, but Black and Hispanic people are less likely to engage in routine physical activity. Concepts from behavioral economics have been used to design scalable, low-touch, gamification interventions that increase physical activity in individuals at high risk for cardiovascular events, but the effectiveness of these strategies in Black and Hispanic survivors of breast and prostate cancer is uncertain. ALLSTAR (NCT05176756) is a pragmatic, virtual, randomized controlled trial designed to evaluate the effectiveness of a gamification intervention informed by behavioral economic concepts to increase daily physical activity in Black and Hispanic breast and prostate cancer survivors who received cardiotoxic therapies and have additional risk factors for cardiovascular disease. Patients were either referred by their cancer care team or identified by electronic health record searches; contacted by letter, email, text message and/or phone; and complete enrollment and informed consent on the Penn Way to Health online platform. Patients are then provided with a wearable fitness tracker, establish a baseline daily step count, set a goal to increase daily step count by 1500-3000 steps from baseline, and are randomized 1:1 to control or gamification. Interventions continue for 6 months, with follow-up for an additional 3 months to evaluate the durability of behavior change. The trial has met its enrollment goal of 150 participants, with a primary endpoint of change from baseline in daily steps over the 6-month intervention period. Key secondary endpoints include change from baseline in daily steps over the 3-month post-intervention follow-up period, change in moderate to vigorous physical activity over the intervention and follow-up periods, and change in patient-reported measures of physical function, fatigue, and overall quality of life. ALLSTAR is a virtual, pragmatic randomized clinical trial powered to demonstrate whether gamification is superior to control in increasing physical activity in Black and Hispanic breast and prostate cancer survivors. Its results will have important implications for strategies to promote physical activity in survivors of breast and prostate cancer, specifically among minority populations. clinicaltrials.gov; https://clinicaltrials.gov/study/NCT05176756.

Racial and ethnic disparities in mental health among breast cancer patients and survivors in the United States.

To decompose the mental health disparities between breast cancer patients and survivors (hereafter survivors) of racial and ethnic minority groups and non-Hispanic White survivors into the contributions of individual-, interpersonal-, community-, and societal-level determinants. We used data from the 2010-2020 Medical Expenditure Panel Survey Household Component (MEPS-HC). Our primary outcome was whether the person had mental health conditions or not. We employed the Kitagawa-Oaxaca-Blinder (KOB) method to understand to what extent the differences in outcomes were explained by the differences in the determinants between non-Hispanic Black or Hispanic breast cancer survivors and non-Hispanic White survivors. We also bifurcated the Hispanic sample analysis by the US-born status (and county of origin). Confidential geographic identifiers are utilized to supplement the MEPS-HC data with information on community characteristics and local healthcare resources. The prevalence of mental health conditions among non-Hispanic Black and Hispanic breast cancer survivors was 26.1% (95% CI: 20.4, 31.7) and 28.3% (95% CI: 21.9, 34.6), respectively. These rates were higher than those for their non-Hispanic White counterparts, 19.7% (95% CI: 17.4, 21.9). In our KOB model, the disparity between non-Hispanic Black and White survivors was fully explained by differences in education, health, and family structure, with community- and societal-level determinants playing no significant role. Conversely, our KOB model did not explain any of the overall differences between Hispanic and non-Hispanic White survivors. However, for foreign-born Hispanic survivors, the disparity was fully explained by a combination of individual- and societal-level determinants. Our findings, which identify specific individual-, interpersonal-, and societal- determinants that were associated with racial and ethnic differences in mental health, can be used by clinicians and policymakers to proactively address racial and ethnic disparities in health.

Abstract C036: Prevalence of and racial/ethnic differences in hearing and balance problems in a multiethnic cohort of patients with breast cancer

Abstract Background: Patients with breast cancer face many health issues during the cancer care continuum. Chemotherapy and radiotherapy can cause hearing and balance problems, e.g., tinnitus, hearing loss, and vertigo or persistent dizziness, negatively affecting patients’ health outcomes and quality of life. Hearing loss is more prevalent among cancer survivors than in the general population. However, little attention has been paid to tinnitus, hearing loss, and vertigo specifically among breast cancer patients and survivors, and it is unclear whether these symptoms vary across racial/ethnic groups. Methods: Between July and September 2023, we surveyed patients enrolled in the Chicago Multiethnic Epidemiologic Breast Cancer Cohort about whether they experienced tinnitus, hearing loss, and/or vertigo. Racial/ethnic groups included Asian or Pacific Islander (API), Black, Hispanic, and White. To examine racial/ethnic differences in hearing and balance problems, we fit separate multivariable logistic regression models, controlling for sociodemographic and clinicopathologic factors. Adjusted odds ratios (AOR) and 95% CIs were calculated. Results: Of 1,462 patients, the mean age was 54.2 years (SD 11.4), with a median duration from diagnosis to survey of 8.2 years (IQR: 5.0-12.4). Most were White (69.8%), followed by Black (22.7%), API (3.8%), and Hispanic (3.7%); and 46.0% received chemotherapy. Overall, 15.1%, 13.6%, and 7.7% reported experiencing tinnitus, hearing loss, and vertigo, respectively. Similar prevalences of these symptoms were observed among survivors who had received chemotherapy. By race/ethnicity, 16.1% of Black patients reported experiencing tinnitus compared to 15.6% of White, 9.4% of Hispanic, and 3.8% of API patients (P=.050). White patients reported a higher proportion of hearing loss (15.5%) than Hispanic (14.8%), Black (8.0%), and API (7.8%) patients (P=.004). A higher percentage of Black patients (13.2%) reported experiencing vertigo than White (6.5%), Hispanic (5.7%), and API (1.9%) patients (P=.001). After adjusting for demographic and clinical characteristics, Black patients had lower odds of experiencing hearing loss than White patients (AOR 0.39, 95% CI: 0.20-0.75). Compared with White patients, Black patients had greater odds of experiencing vertigo (AOR 1.80, 95% CI: 1.01-3.21). Due to limited power, we did not observe statistically significant differences in vertigo or hearing loss between API or Hispanic survivors and White survivors and in tinnitus across racial/ethnic groups. Older age and longer duration from diagnosis to survey were associated with greater odds of tinnitus or hearing loss. Conclusions: In this multiethnic cohort, hearing and balance problems were prevalent and varied by race/ethnicity among breast cancer patients. Our findings suggest that oncology programs should consider routine screening for these symptoms, encourage patient-provider discussion to identify unmet needs, and address racial/ethnic disparities to improve hearing and balance-related quality of life of breast cancer survivors.

Abstract C062: Racial and ethnic disparities in risk of second primary non-breast cancer in breast cancer survivors

Abstract Purpose: Disparities in cancer outcomes are multifactorial and are attributed to differences in access to care, socioeconomic status, tumor characteristics, treatment, family history, and comorbidity burden. Studies evaluating disparities in breast cancer outcomes have mostly been restricted to Black and White patients. Additionally, whether racial and ethnic disparities affect the risk of second primary cancer in breast cancer survivors, remains under-studied. We evaluated disparities in risk of second primary non-breast cancer in a racially and ethnically diverse cohort of breast cancer survivors treated at an integrated healthcare system. Methods: This retrospective cohort study included 37,222 breast cancer patients (aged ≥18 years) diagnosed between 2008-2020 at Kaiser Permanente Southern California (KPSC). Data on tumor characteristics, cancer treatments and sociodemographic variables were extracted from KPSC’s cancer registry and electronic health records. Patients were followed electronically from breast cancer diagnosis until they developed second primary non-breast cancer, died, disenrolled from the health plan, or reached study’s end (12/31/2021), whichever occurred first. Cox proportional hazards regression was used to report the association [Hazard Ratio (95% Confidence Interval)] between race and ethnicity and second primary non-breast cancer. Results: More than half of the study cohort consisted of non-Hispanic White survivors (51.2%), followed by 20.9% Hispanic survivors, 13.9% Asian/Pacific Islander (API) survivors, 12.7% non-Hispanic Black survivors, and 1.3% survivors of other/mixed races. Overall, 55.7% and 23.9% were diagnosed with local and regional breast cancer, respectively. During a median follow-up of 5.2 years, 4.6% survivors developed second primary non-breast cancers. In the multivariable model adjusted for sociodemographic characteristics, breast tumor characteristics, and breast cancer treatments, Hispanic and API survivors were 25% and 28% less likely to develop second primary cancer compared to White survivors [adjusted HR (95%CI): 0.75 (0.65-0.86)] and 0.72 (0.61-0.86), respectively]. We did not find an increased risk in Black survivors compared to White survivors [adjusted HR (95%CI): 0.91 (0.78-1.04)]. However, factors related to higher risk of second primary non-breast cancers were older age at breast cancer diagnosis, smoking, and higher comorbidity burden. Conclusion: Interestingly, risk of second primary non-breast cancer was lower in Hispanic and API survivors compared to White survivors in this insured cohort. Next steps will include examining which lifestyle factors (e.g. less smoking), or if pharmacological management of modifiable comorbidities might have played a role in the decreased risks seen in these two racial and ethnic groups.

Abstract B014: Cannabis use among cancer survivors and its association with cardiometabolic risk factors: Findings from the All of Us Research Program

Abstract Purpose: Cannabis use has been linked to alleviating symptoms such as sleep issues, mental health, and physical problems resulting from cancer treatment among cancer survivors. However, in the US general population, evidence suggests that an increase in cannabis use increases the risk for cardiovascular disease including high blood pressure, type 2 diabetes, and high cholesterol. This is even more alarming since users who have been diagnosed with cancer have an even greater independent risk of cardiovascular events due to the toxicities of cancer therapeutic drugs. Given the US trend in cannabis legalization and decriminalization and the limited knowledge of the association between cannabis use and cardiometabolic biomarkers among cancer survivors, we aim to assess the independent associations between cannabis use and several cardiometabolic biomarkers and explore racial/ethnic and sex differences among a sample of cancer survivors from the All of Us (AoU) Program. Methods: Cross-sectional cannabis data and cardiometabolic risk factor biomarkers were obtained from adult cancer survivors in the AoU Research Program from 2018-2022. Cannabis use was defined as never use (in a lifetime or past three months), occasional use (twice or monthly in the past three months), and frequent/regular use (weekly or daily). Cardiometabolic outcomes included cardiovascular (e.g., systolic, diastolic blood pressure, hypertension), immune (i.e., White Blood Cell [WBC] counts, C-reactive protein [CRP]), and metabolic systems biomarkers (e.g. waist-to-hip ratio, lipids, HbA1c), were dichotomized from continuous values to elevated vs normal where high values, defined by clinically established cutoffs or >75th percentile, represented elevated biomarkers. Multivariable logistic regression and stratified models if interactions were statistically significant, adjusting for treatment, smoking, hazardous alcohol use, and sociodemographic variables were used. Results: Our cohort (N=6,985) consisted of 7.6% Hispanic, 6.2% Black, and 86.2% White survivors. Overall, 8.2% of survivors reported occasional and frequent/regular cannabis use, with Black survivors (9.7%) reporting a greater proportion of frequent/regular use compared to White (3.2%) and Hispanic (4.7%) survivors. Similarly, female (2.8%) survivors reported a lower frequency of frequent/regular cannabis use compared to male (4.2%) survivors. Compared to never users, frequent/regular users were 3.35(95% CI=1.10-10.53) times as likely to report elevated WBC count. No significant associations were found between cannabis use and CRP, cardiovascular, and metabolic systems biomarkers. Similarly, no race/ethnicity or sex (both pinteraction > 0.05) differences were found in the cannabis and WBC association. Conclusion: Our results underscore that more frequent cannabis use may have a detrimental effect on immune risk factors like WBC counts among survivors. Being that high WBC may be predictive of cardiovascular diseases and mortality, future studies should explore the longitudinal effects of cannabis use on WBC.

Abstract A120: Cancer screening uptake among Hispanic survivors of adolescent and young adult cancer

Abstract Introduction: Advances in treatment have significantly improved the survival rates of adolescent and young adult (AYA) cancer patients, with a five-year survival rate reaching 86%. However, these survivors remain at increased risk for developing secondary cancers later in life. Racial and ethnic minority groups, such as Hispanics, often experience significant healthcare disparities, including lower cancer screening rates. Cancer survivors, particularly those who are Hispanic and diagnosed as AYAs, may face unique barriers in adhering to recommended cancer screening guidelines. This study examines the uptake rates of colon, breast, and cervical cancer screenings among Hispanic survivors of AYA cancer compared to their age- and sex-matched Hispanic non-cancer controls. Methods: The National Health Interview Survey data (years 2000 - 2021) [R1] were analyzed to identify Hispanic survivors of AYA cancer and Hispanic age- and sex-matched non-cancer controls. Data on cancer screening, including whether patients were up- to-date and ever screened for colon, breast, and cervical cancers, were assessed. The US Preventive Services Task Force recommendations were used to determine whether survivors were up-to-date for the cancer screening tests. The sample included 92 colon cancer survivors, 113 breast cancer survivors, and 313 cervical cancer survivors, matched with 920, 1130, and 3130 controls, respectively. Weighted percentages and odds ratios (OR) were calculated, adjusting for age at survey, sex, marital status, education, poverty status, and insurance. Results: Colon cancer screening uptake was significantly higher among survivors, with 26.1% up-to-date versus 11.5% of controls (OR=2.49, 95% CI=1.17-5.30, p=0.019). For breast cancer, 14.6% of survivors were up-to-date compared to 5.1% of controls [R2] (OR=2.51, 95% CI=1.33-4.72, p=0.005), and 82.6% of survivors were ever screened versus 38.7% of controls (OR=7.41, 95% CI=4.43-12.41, p<0.001). Cervical cancer screening showed the most pronounced difference, with 40.6% of survivors up-to-date compared to 19.0% of controls (OR=3.36, 95% CI=2.43- 4.65, p<0.001), and 71.2% of survivors ever screened compared to 28.6% of controls (OR=14.16, 95% CI=8.56-23.40, p<0.001). Conclusion: Hispanic AYA cancer survivors exhibit significantly higher cancer screening rates compared to matched controls. Despite these positive findings, the overall low screening rates highlight the need for targeted interventions to ensure that all survivors adhere to recommended screening guidelines. Enhancing access to healthcare and ensuring continuity of care are critical steps toward reducing disparities and improving health outcomes for this vulnerable population.

Disparities in self-reported pain control among cancer survivors.

151 Background: Cancer survivors often suffer from chronic pain. However, not all patients have access to medication and other pain management strategies, making pain control challenging. We aim to determine the association of sociodemographic factors with self-reported pain control in cancer survivors with cancer-related chronic pain. Methods: A cross-sectional analysis was conducted using data from the 2022 Behavioral Risk Factor Surveillance System survey. Cancer survivors who self-reported physical pain from cancer or treatment were included. Non-melanoma skin cancer survivors were excluded. The outcome of interest was pain control. Univariate analysis with chi-square and multivariable logistic regression were used to determine the sociodemographic characteristics associated with pain control. Models were adjusted for age, sex, marital status, income, insurance coverage, BMI, smoking status, and cancer site. Results: 1,670 cancer survivors with self-reported cancer-related chronic pain were identified. 9.2% were aged < 40, 61.5% were female, and 71.6% were non-Hispanic white. 97.2% were insured, 50.5% earned ≥ $50,000, and 27.6% were college graduates. 29.8% of survivors reported a history of breast cancer, followed by melanoma (6.3%), and lung cancer (6.1%). Young adults (age 18-39) reported significantly lower pain control compared to older survivors (52% vs. 77.7%, p <0.001). Non-Hispanic Black survivors reported the highest rates of pain control, followed by non-Hispanic white, and Hispanic survivors (87.7% vs. 77.5% vs. 60.6%, respectively, p= 0.013). Employed survivors reported significantly higher pain control than those out of the workforce (83.2% vs. 73.7%, p= 0.008, respectively). College graduates reported better pain control than those without a college degree (82.9% vs. 74.7%, p=0.009, respectively). There was no significant association between pain control and insurance coverage or income. On multivariate analysis, young adults had lower pain control than older adults (OR: 0.454; 95% CI: 0.219-0.942). Compared to non-Hispanic white survivors, being Hispanic was associated with worse pain control (OR: 0.324; 95% CI: 0.142-0.737); no significant association was found for non-Hispanic Black survivors (OR: 1.964; 95% CI: 0.851-4.631). Employment was associated with better pain control (OR: 1.997; 95% CI: 1.235-3.231). College degree attainment was not significantly associated with pain control on multivariate analysis (OR: 1.414; 95% CI: 0.934-2.142). Conclusions: Age, race/ethnicity and employment were associated with pain control among cancer survivors. Young adults, Hispanic and unemployed survivors were most likely to have poor pain control. Further research should elucidate the factors driving these relationships in order to achieve more equitable pain management in this population.

Association between perceived quality of care and social isolation among cancer survivors in the US.

e23182 Background: Though social isolation has been linked to poorer survival outcomes among cancer survivors, studies assessing its association with perceived quality of care have not been explored in this population. We examined the association between perceived quality of care and self-reported social isolation among cancer survivors. Methods: Cross-sectional analyses were conducted using the Health Information National Trends Survey (HINTS) data collected from a nationally representative population of US adults from March to November 2022. Social isolation was assessed with the self-reported Patient-Reported Outcomes Measurement Information System (PROMIS) Social Isolation Short Form. Multiple linear regression models were used to examine the association between perceived quality of care and self-reported social isolation among cancer survivors. Other factors associated with social isolation in this population were also assessed. Results: In the adjusted analyses, social isolation scores were 6.3 points (95% CI: 2.30–10.28) higher among cancer survivors who reported fair/poor quality health care relative to those that reported excellent/very good/good quality of care. When compared to Non-Hispanic White cancer survivors, Non-Hispanic Blacks (β: –2.96; 95% CI: –5.35– –0.57) and Hispanic survivors (β: –4.06; 95% CI: –7.71– –0.40) had lower social isolation scores. Cancer survivors who were married or cohabiting had 3.3 points (95% CI: –6.01– –0.55) lower social isolation scores relative to single cancer survivors. Cancer survivors with high school or less education had lower isolation scores (β: –2.03; 95% CI: –4.00– –0.07) than those with some college education or more and those with an income of $50,000 or higher reported lower isolation scores (β: –2.19; 95% CI: –4.17– –0.21) than their counterparts earning less than $50,000. Furthermore, those with a diagnosis of depression or anxiety had 5.2 points (95%: 3.23–7.21) higher social isolation scores than cancer survivors without depression/anxiety. Conclusions: Fair or poor quality of care was associated with higher social isolation among cancer survivors. Additionally, race/ethnicity, marital status, level of education, income, and depression/anxiety were correlated with social isolation. To reduce the impact of social isolation and improve the health outcomes of cancer survivors, healthcare providers need to prioritize delivering holistic care, promote social connectivity and incorporate mental health screening and referrals into standard care practices.

Institutional Betrayal in the Criminal and Civil Legal Systems: Exploratory Factor Analysis with a Sample of Black and Hispanic Survivors of Intimate Partner Violence.

Institutional betrayal (IB) is well-documented among survivors of gender-based violence seeking help and/or reporting incidents of violence in various settings, including college campuses and health care settings. Two of the most common institutions from which survivors seek help are the criminal and civil legal systems; however, less is known about the experiences of IB among survivors interfacing with those systems. Previous studies exploring IB have implemented the Institutional Betrayal Questionnaire (IBQ) and its various adaptations, but this scale has not yet been analyzed in the criminal or civil legal context, nor has it been analyzed among racially marginalized survivors. This paper explores the potential for utilizing the IBQ-Health among a sample of 199 Black and Hispanic survivors of intimate partner violence (IPV) who sought help from the criminal and/or civil legal system(s). An exploratory factor analysis was conducted to explore the fit of the measure to the data. Results suggest that the measure as it has previously been used does not demonstrate strong reliability or fit with this population or institution. Possible explanations and future directions are explored, including support for developing and piloting a new measure to assess IB among Black and Hispanic survivors of interpersonal violence who are seeking help from criminal and civil legal institutions.

Racial/Ethnic Disparities: Discrimination's Impact on Health-Related Quality of Life-An All of Us Cancer Survivors' Cross-sectional Study.

Discrimination is associated with worse mental and physical health outcomes. However, the associations among cancer survivors are limited. We examined whether discrimination is associated with HRQoL and whether adjusting for it reduces racial/ethnic disparities in HRQoL among cancer survivors. Cross-sectional data from adult cancer survivors who completed surveys on discrimination in the medical settings (DMS), everyday perceived discrimination (PD), and HRQoL in the "All of Us" Program from 2018 to 2022 were assessed. We created a binary indicator for fair-to-poor vs. good-to-excellent physical health and mental health. PD and DMS scores were a continuous measure with higher scores reflecting more discrimination. Multivariable logistic regression models tested whether DMS and PD are associated with HRQoL and whether they differently affect the association between race/ethnicity and HRQoL. The sample (N = 16,664) of cancer survivors was predominantly White (86%) and female (59%), with a median age of 69. Every 5-unit increase in DMS and PD scores was associated with greater odds of fair-to-poor physical health (DMS: OR [95%CI] = 1.66 [1.55, 1.77], PD: 1.33 [1.27, 1.40]) and mental health (DMS: 1.57 [1.47, 1.69], PD: 1.33 [1.27, 1.39]). After adjusting for DMS or PD, Black and Hispanic survivors had a decreased likelihood of fair-to-poor physical health and mental health (decrease estimate range: - 6 to - 30%) compared to White survivors. This effect was greater for Black survivors when adjusting for PD, as the odds of fair-to-poor mental health compared to White survivors were no longer statistically significant (1.78 [1.32, 2.34] vs 1.22 [0.90, 1.64]). Experiences of discrimination are associated with lower HRQoL and reducing it may mitigate racial/ethnic disparities in HRQoL.

Abstract 3474: Racial disparities in receipt of surveillance mammography after breast cancer diagnosis

Abstract Background: The 5-year survival rate for breast cancer (BC) stands at an estimated 91%, with approximately 3.8 million BC survivors in the U.S. This large population of breast cancer survivors remains at risk of loco-regional recurrence, with variations noted across racial groups. White survivors face a locoregional breast cancer recurrence rate of 1.8%, whereas Black, Asian, and Hispanic survivors experience higher rates of 3.9%, 3.6%, and 3.1%, respectively. Notably, Black BC survivors with recurrent breast cancer exhibit a median survival time of 1.8 years compared with 3.6 years observed for White BC survivors. Current recommendations from the U.S. Preventative Services Task Force and the American College of Radiology advocate for surveillance through annual mammography and routine clinical visits following breast-conserving surgery and lumpectomies. However, there are gaps in the data available regarding disparities in the utilization of surveillance mammography by race/ethnicity. Thus, the goal of this study is to estimate race/ethnic disparities in surveillance mammography utilization and its impact on survival among breast cancer survivors at a large comprehensive cancer center. Methods: A retrospective cohort study of female breast cancer survivors ≥19 years diagnosed and/or treated at the Duke Cancer Institute (DCI) between 2014 and 2022 was conducted. Data was abstracted on patient socio-demographics, cancer type (invasive ductal and ductal in situ carcinomas) and utilization of surveillance mammography within 2-5 years post initial breast cancer diagnosis. Chi-squared testing will be used to analyze rates of mammography surveillance receipt among different races presenting with BC at DCI. Kaplan-Meier estimates will be used for analysis on survival. Results: A total of 10,904 women with a mean age of 43.7 years were included in the study. The study cohort is comprised of 69% non-Hispanic (NH) White, 24% NH Black, 2.2% Hispanic, 0.5% NH Native American, 1% NH other, and 3.2% NH Asian women. There were 1,791 cases of ductal in situ carcinomas and 9,113 invasive ductal carcinoma cases. NH Black women had the lowest 5-year relative survival rate (81.5%) of all represented racial groups: NH White 89.1%, Hispanic 95.3%, NH Native 87.8%, Asian 97.9%, and NH Other 88.0%. Ongoing analysis will be completed to estimate disparities in the use of post-treatment surveillance mammography amongst breast cancer survivors. Conclusions: This study will inform efforts to increase post-treatment surveillance and improve adherence to survivorship guidelines with the ultimate goal of reducing mortality disparities among breast cancer survivors.

Cultural and linguistic adaptation of a telephone-based cognitive-behavioral therapy (CBT) intervention to treat depression and anxiety in Hispanic cancer survivors

Purpose/Objectives The purpose of this study was to transcreate a manualized cognitive-behavioral therapy (CBT) intervention to address depression and anxiety among Hispanic cancer survivors. Design/Research Approach Stakeholders reviewed the CBT workbook for language, content, and cultural relevance. We designed semi-structured interview guides to elicit intervention feedback. Sample/Participants Stakeholder participants were Hispanic cancer survivors (n = 4), bilingual mental health providers (n = 2), and oncology professionals (n = 4). Methods Transcreation was conducted by initial translation of the workbook followed by incorporation of stakeholder feedback. A bilingual (Spanish and English) interviewer conducted stakeholder interviews. The study team discussed themes/suggestions before refining the workbook. Findings Stakeholders reported enthusiasm for the intervention. We gathered significant feedback regarding wording, images, and resources for the workbook. Conclusion Development of culturally appropriate mental health resources for Hispanic cancer survivors is critical. Implications for Psychosocial Providers or Policy By broadening research on psychosocial care to the Hispanic population, we increase the reach of evidence-based psychological care. Future research should fully evaluate the adapted CBT intervention among Hispanic survivors.

Abstract B129: The association of Covid-19 pandemic restrictions with patient-reported outcomes and lifestyle behaviors among breast cancer survivors: Evidence from a cohort of Black and Hispanic breast cancer survivors in New Jersey

Abstract Purpose: The onset of COVID-19 pandemic restrictions in the US since March 2020 has worsened the disproportionate burden of physical and mental health challenges faced by vulnerable Black and Hispanic breast cancer (BrCa) patients. BrCa survivors experienced delays in their cancer treatments and limited access to supportive care, which may lead to further physical, and psychosocial challenges during an already difficult time. This study aimed to evaluate the association of the COVID-19 pandemic restrictions with patient-reported outcomes (PROs) (i.e. health-related quality of life (HRQoL), sleep, perceived stress, coping and financial toxicity), and lifestyle behaviors (i.e. obesity, smoking, and alcohol) among Black and Hispanic BrCa survivors participating in the Women’s Circle of Health Follow-Up 1 (WCHSFU1) and the New Jersey Breast Cancer Survivors Study (NJBCS), two ongoing population-based studies in New Jersey. Methods: The NJBCS followed similar methods to those in the WCHSFU1. We included a total of 447 Black (npre=364 and npost=83) and 182 Hispanic (npre=102 and npost=80) BrCa survivors who completed a home interview ~24 months post-diagnosis, from 2017 to 2023. The COVID-19 pandemic era was defined as pre- (recruited prior to March 2020) and post-(recruited after March 2020) pandemic. To assess the association of the pandemic with PROs and lifestyle behaviors we employed multivariable adjusted Poisson regression models with robust standard errors to estimate prevalence ratios with 95%CI. Results: Compared to the pre-pandemic group, Black survivors in the post-pandemic group were more likely to be educated, to have higher income, and to be foreign-born, while Hispanic women were significantly more likely to have private insurance and higher HRQoL, physical and emotional well-being mean scores (p<0.05 for all). Adjusted Poisson models indicated that Hispanic women in the post-pandemic group had 1.53 times higher prevalence of low resilience (vs high resilience) (PR:1.53 95% CI: 1.15-2.04), compared to the pre-pandemic group. Whereas Black women in the post-pandemic group reported a higher prevalence of clinically significant sleep disturbance and efficiency (PR: 1.43 95% CI: 1.23-1.68 and PR:1.50 95% CI: 1.30 – 1.73, respectively), compared to the pre-pandemic group. Both Hispanic and Black women in the post-pandemic group showed significantly less perceived stress and a lower prevalence of alcohol consumption. Conclusion: We found heterogeneity in the prevalence of PROs and lifestyle behaviors by pandemic era among Black and Hispanic survivors. Notably, we also noticed differences in demographic characteristics of women participating after the onset of the pandemic, which highlights the importance of considering the impact of the pandemic in all aspects of research, including the interpretation of findings. Continuing research to untangle important factors contributing to racial and ethnic differences in patient characteristics, PROs and lifestyle behaviors post-pandemic in cancer survivorship is warranted.

Abstract A002: Alcohol use patterns and patient-provider discussions about alcohol use among cancer survivors: Differences by race and ethnicity in the National Survey of Drug Use and Health

Abstract Background: Alcohol is a leading modifiable risk factor for cancer risk and recurrence. The American Cancer Society recommends abstaining from alcohol for cancer prevention and advises that those who choose to drink should limit their intake. Healthcare providers are uniquely positioned to counsel cancer survivors about alcohol’s harms. Prior research has revealed stark differences in heavy drinking among cancer survivors by race and ethnicity. We build on this work by examining the prevalence of multiple alcohol use patterns, alcohol screening, and patient-provider discussions about alcohol by race and ethnicity among a cancer survivor population. Methods: We conducted a cross-sectional study using data from the National Survey on Drug Use and Health (NSDUH) 2015-2019. Eligible respondents included adults (18+ years) who reported a prior cancer diagnosis. Outcomes included alcohol use patterns (lifetime abstention, alcohol use and binge drinking in the past 30 days), alcohol screening in the past year, and report of an in-person alcohol discussion with a healthcare provider in the past year. We estimated the adjusted prevalence of these outcomes by race and ethnicity from marginal effects of logistic regression models that accounted for sociodemographic characteristics (i.e., age, gender, educational attainment, household income) and health insurance type. Models included cluster, strata, and weight variables to account for the complex survey design and nonresponse bias. Results: The unweighted analytic sample size included 6,240 cancer survivors – 431 identified as Black, Non-Hispanic; 461 identified as Hispanic, and 5,348 identified as White, Non-Hispanic. Though not statistically significant, adjusted binge drinking prevalence was highest among Black, Non-Hispanic survivors (17.3% [95% CI: 11.6 – 23.0]) followed by White survivors (13.4% [95% CI: 12.2 – 14.6]) and Hispanic survivors (13.1% [95% CI: 9.8 – 16.4]). Significant differences in adjusted binge drinking prevalence by race and ethnicity were found for binge drinking among current drinkers – Black (41.4% [95% CI: 30.7 – 52.1]), Hispanic (31.7% [95% CI: 22.6 – 40.8]), White (26.7% [95% CI: 24.6 – 28.8]). No significant differences were found for alcohol screening prevalence by race and ethnicity. Black (44.7% [955 CI: 36.4 – 53.0]) and Hispanic (48.8% [95% CI: 40.1 – 57.6%]) cancer survivors were less likely than White survivors (56.9% [95% CI: 54.9 – 59.0]) to report an in-person provider discussion about alcohol. Conclusions: There is a significant racial disparity in problematic drinking between Black, Hispanic, and White cancer survivors, with higher proportions of Black and Hispanic survivors reporting binge drinking than their White peers. Yet, Black and Hispanic cancer survivors are less likely to have an in-person discussion with a provider about alcohol use compared with White cancer survivors. Black and Hispanic cancer survivors may not be receiving important messages about alcohol’s harms from their providers, who could be important sources of this information. Citation Format: Naomi K.

Associations between race/ethnicity and SEER-CAHPS patient care experiences among female Medicare beneficiaries with breast cancer

IntroductionWe aimed to determine if racial/ethnic disparities exist in survivorship care patient experiences among older breast cancer survivors. Materials and MethodsNineteen thousand seventeen female breast cancer survivors aged ≥65 at post-diagnosis survey contributed data via the National Cancer Institute Surveillance, Epidemiology, and End Results (SEER) and Centers for Medicare and Medicaid Services Consumer Assessment of Healthcare Providers & Systems (CAHPS) data linkage (2000–2019). Multivariable linear regression models were used to estimate adjusted beta (β) coefficients and standard error (SE) estimates for associations between race/ethnicity and survivorship care patient experiences. ResultsMost women were non-Hispanic (NH)-White (78.1%; NH-Black [8.1%], NH-Asian [6.5%], Hispanic [6.2%]). On average, women reported 76.3 years (standard deviation [SD] = 7.14) at CAHPS survey and 6.10 years since primary diagnosis (SD = 3.51). Compared with NH-White survivors, NH-Black survivors reported lower mean scores for Getting Care Quickly (β = −5.17, SE = 0.69, p ≤0.001), Getting Needed Care (β = −1.72, SE = 0.63, p = 0.006), and Overall Care Ratings (β = −2.72, SE = 0.48, p ≤0.001), mirroring the results for NH-Asian survivors (Getting Care Quickly [β = −7.06, SE = 0.77, p ≤0.001], Getting Needed Care [β = −4.43, SE = 0.70, p ≤0.001], Physician Communication [β = −1.15, SE = 0.54, p = 0.03], Overall Care Rating [β = −2.32, SE = 0.53, p ≤0.001]). Findings among Hispanic survivors varied, where mean scores were lower for Getting Care Quickly (β = −2.83, SE = 0.79, p ≤0.001), Getting Needed Care (β = −2.43, SE = 0.70, p = 0.001), and Getting Needed Prescription Drug(s) (β = −1.47, SE = 0.64, p = 0.02), but were higher for Health Plan Rating (β = 2.66, SE = 0.55, p ≤0.001). Education, Medicare plan, and multimorbidity significantly modified various associations among NH-Black survivors, and education was a significant modifier among NH-Asian and Hispanic survivors. DiscussionWe observed racial/ethnic disparities in the associations with survivorship care patient experience among NH-Black, Hispanic, and NH-Asian breast cancer survivors. Future research should examine the impact of education, Medicare plans, and multimorbidity on these associations.

Depressive symptoms and physical activity among young adult survivors of childhood cancer.

Young adult survivors of childhood cancers are less likely to be physically active compared to non-cancer affected controls, putting them at an increased risk for morbidity and mortality. Preliminary research has examined how mental health may contribute to physical activity (PA) in this population; however, those more recently diagnosed and Hispanic survivors have been understudied. The objectives were to examine associations of dimensions of depressive symptoms, demographic characteristics, and cancer-related predictors with PA among a diverse sample of young adult childhood cancer survivors. Participants (N=895) diagnosed with childhood cancer between 1996 and 2010 (53% Hispanic; Mage =26.2±4.9years; Mage =14.8±4.4years at diagnosis) were recruited from the Los Angeles County cancer registry. Self-report surveys assessed current PA, depressive symptoms (i.e., positive affect, negative affect, somatic symptoms, interpersonal problems), late effects of cancer treatment, and demographic factors. Multivariable ordinal regressions examined the study objectives. About 70% of participants engaged in low or moderate frequency PA (fewer than 3days a week). Participants who were older, female, Asian, or reported more late effects of cancer treatment were less likely to engage in PA. Greater positive affect was significantly associated with higher frequency PA, whereas negative affect, somatic symptoms, and interpersonal problems were not associated with PA. The findings suggests that positive-but not negative-mental health characteristics are more likely to facilitate or result from PA among young adult survivors of childhood cancers. Interventions seeking to increase PA may benefit from considering positive aspects of mental health/well-being.

Cardiovascular Risk Factor Disparities in Adult Survivors of Childhood Cancer Compared With the General Population.

It is unknown whether a history of childhood cancer modifies the established disparities in cardiovascular risk factors (CVRFs) observed in the general population. We sought to determine if disparities in CVRFs by race/ethnicity are similar among childhood cancer survivors compared with the general population. The Childhood Cancer Survivor Study (CCSS) is a retrospective cohort with a longitudinal follow-up of 24,084 5-year survivors diagnosed between 1970 and 1999. Multivariable piecewise exponential regression estimated incidence rate ratios (IRRs) for hypertension, hyperlipidemia, diabetes, obesity, and≥2 CVRFs by race/ethnicity. The CCSS sibling cohort and the National Health and Nutrition Examination Survey cohort were used to compare the sociodemographic-adjusted IRRs for same-race/same-ethnicity disparities. Non-Hispanic Black (NHB) (n=1,092) and Hispanic (n=1,405) survivors compared with non-Hispanic White (NHW) (n=13,960) survivors reported a higher cumulative incidence of diabetes (8.4%, 9.7%, and 5.1%, respectively); obesity (47.2%, 48.9%, and 30.2%, respectively); multiple CVRFs (17.7%, 16.6%, and 12.3%, respectively); and, for NHB survivors, hypertension (19.5%, 13.6%, and 14.3%, respectively) by 40 years of age (P< 0.001). Controlling for sociodemographic and treatment factors compared with NHW survivors, IRRs for NHB were increased for hypertension (IRR: 1.4; 95% CI: 1.1-1.8), obesity (IRR: 1.7; 95% CI: 1.4-2.1), and multiple CVRFs (IRR: 1.6; 95% CI: 1.2-2.1). IRRs for Hispanic survivors were increased for diabetes (IRR: 1.8; 95% CI: 1.2-2.6) and obesity (IRR: 1.4; 95% CI: 1.2-1.7). The pattern of IRRs for CVRF differences was similar among CCSS sibling and National Health and Nutrition Examination Survey cohorts. The higher burden of CVRFs among NHB and Hispanic survivors compared with NHW survivors was similar to the general population. The promotion of cardiovascular health equity is critical in this high-risk population.

Medicaid enrollment changes among U.S. adult survivors of childhood cancer following medicaid expansion: A report from the Childhood Cancer Survivor Study (CCSS).

10011 Background: Little is known about whether Medicaid expansion under the Affordable Care Act (ACA) affected insurance coverage among adult survivors of childhood cancer, a population at high-risk for poor health outcome. We addressed this gap by evaluating the association between ACA Medicaid expansion and Medicaid enrollment among participants in the Childhood Cancer Survivor Study (CCSS). Methods: The CCSS cohort of 5-year survivors of childhood cancer was linked to administrative Medicaid insurance data in 2010-2016. We identified 13,895 adult survivors (aged 18-64 years) diagnosed with cancer under age 21 and between 1970 and 1999. Outcomes included (1) percentage with any Medicaid enrollment by year; and (2) Medicaid-covered days (number of days when a survivor was enrolled in Medicaid) during each year. Multivariable difference-in-differences (DD) models were used to examine outcome changes pre vs. post ACA Medicaid expansion, in expansion- vs. non-expansion states, adjusting for age, sex, race/ethnicity, income, education, and chronic conditions. Multivariable models were conducted overall and then stratified by cancer type, race/ethnicity, income, and education. Results: Medicaid enrollment rates increased more in expansion states (17.6% pre-expansion to 24.1% post-expansion) than non-expansion states (16.4% to 16.9%), leading to a net increase in enrollment of 6.6 percentage points (ppt; 95% CI = 5.5-7.7) in the multivariable DD model. Multivariable DD model showed a net increase of 18.4 days (95% CI = 13.8-23.1) in Medicaid-covered days in expansion states relative to non-expansion states. The expansion-associated increase in Medicaid enrollment rates was greatest among survivors of leukemia (multivariable DD estimate: 8.9 ppt, 95% CI = 6.9-11.0) and non-Hodgkin lymphoma (8.0 ppt, 95% CI = 5.0-10.9). Greater increases in Medicaid enrollment were seen in non-Hispanic Black (13.5 ppt, 95% CI = 8.0-19.1) and Hispanic survivors (15.8 ppt, 95% CI = 10.6-21.0) than non-Hispanic White peers (5.1 ppt; 95% CI = 4.0-6.2); in survivors with &lt; $20K household income (11.7 ppt, 95% CI = 8.9-14.4) compared to those with ≥$60K household income (2.9 ppt, 95% CI = 1.6-4.2); and in survivors with high school or lower education (9.3 ppt, 95% CI = 6.9-11.8) compared to those with a college or higher degree (3.9 ppt, 95% CI = 2.6-5.3). Similar patterns were observed across survivor subgroups when examining Medicaid-covered days. Conclusions: We provide the first evidence on increased Medicaid enrollment and longer coverage duration among adult survivors of childhood cancer following Medicaid expansion, with greater increases seen among survivors of underrepresented racial/ethnic populations, those with low socioeconomic status, and high medical need survivors.

Risk Factors and Trends for HPV-Associated Subsequent Malignant Neoplasms among Adolescent and Young Adult Cancer Survivors.

Subsequent malignant neoplasms (SMN; new cancers that arise after an original diagnosis) contribute to premature mortality among adolescent and young adult (AYA) cancer survivors. Because of the high population prevalence of human papillomavirus (HPV) infection, we identify demographic and clinical risk factors for HPV-associated SMNs (HPV-SMN) among AYA cancer survivors in the SEER-9 registries diagnosed from 1976 to 2015. Outcomes included any HPV-SMN, oropharyngeal-SMN, and cervical-SMN. Follow-up started 2 months after their original diagnosis. Standardized incidence ratios (SIR) compared risk between AYA survivors and general population. Age-period-cohort (APC) models examined trends over time. Fine and Gray's models identified therapy effects controlling for cancer and demographic confounders. Of 374,408 survivors, 1,369 had an HPV-SMN, occurring on average 5 years after first cancer. Compared with the general population, AYA survivors had 70% increased risk for any HPV-SMN [95% confidence interval (CI), 1.61-1.79] and 117% for oropharyngeal-SMN (95% CI, 2.00-2.35); cervical-SMN risk was generally lower in survivors (SIR, 0.85; 95% CI, 0.76-0.95), but Hispanic AYA survivors had a 8.4 significant increase in cervical-SMN (SIR, 1.46; 95% CI, 1.01-2.06). AYAs first diagnosed with Kaposi sarcoma, leukemia, Hodgkin, and non-Hodgkin lymphoma had increased HPV-SMN risks compared with the general population. Oropharyngeal-SMN incidence declined over time in APC models. Chemotherapy and radiation were associated with any HPV-SMN among survivors with first HPV-related cancers, but not associated among survivors whose first cancers were not HPV-related. HPV-SMN in AYA survivors are driven by oropharyngeal cancers despite temporal declines in oropharyngeal-SMN. Hispanic survivors are at risk for cervical-SMN relative to the general population. Encouraging HPV vaccination and cervical and oral cancer screenings may reduce HPV-SMN burden among AYA survivors.

Abstract LB128: Cardiovascular disease mortality among cancer survivors by race and ethnicity in the United States

Abstract Background Cancer survivors have higher cardiovascular disease (CVD) mortality than the general population but comprehensive data by race and ethnicity are limited. Methods Data from 17 Surveillance, Epidemiology, and End Results (SEER) registries were used to identify adults diagnosed with invasive cancer at ages ≥20 years from 2000 to 2018. CVD mortality was calculated for five mutually exclusive race/ethnicity categories (non-Hispanic American Indian/Alaska Native [AIAN], non-Hispanic Asian or Pacific Islander [API], Hispanic, non-Hispanic Black [Black], and non-Hispanic White [White]). Standardized mortality ratios (SMR) were estimated to compare mortality rates in cancer survivors to their counterparts in the general population. Analyses were stratified by demographic factors, CVD subtype, and cancer site. Results During a mean follow up of 5.3 person-years among 5,786,876 survivors (20-64 years, 49.3%; men, 51.2%; White, 71.7%; Black, 10.1%; Hispanic, 10.9%; API, 7%, AIAN, 0.3%), 358,970 CVD deaths (cardiac death, 76.9%; cerebrovascular death, 15.9%) occurred. CVD mortality per 10,000 person-years was highest among survivors who were Black (122.9), followed by White (114.7), AIAN (86.7), API (78.6) and Hispanic (75.3). In contrast, SMRs were greatest among AIAN survivors (SMR=1.42, 95% CI=1.32-1.51), followed by API (SMR=1.39, 1.37-1.41), Hispanic (SMR=1.29, 1.27-1.30), Black (SMR=1.19, 1.17-1.20) and White (SMR=1.08, 1.07-1.08) survivors. Among survivors ages 20-64 years, Black survivors were approximately three times as likely to die from cardiac death as Hispanic or API survivors (46.7 vs. 14.5-17.6 per 10,000). SMR, however, was 1.47 among Hispanic survivors (95% CI=1.42-1.51) and 1.80 among API survivors (95% CI=1.42-1.51), greater than 1.25 among Black survivors (95% CI=1.22-1.27). Across cancer types, the highest SMR was among API survivors of pancreatic cancer (SMR=5.27, 3.83-7.08) and brain cancer (SMR=4.56, 3.10-6.48) in ages 20-64 years and among Hispanic (SMR=3.77, 3.09-4.56) and API survivors of brain cancer (SMR=3.24, 2.40-4.28) in ages ≥65 years. Conclusion Black survivors had the greatest CVD mortality of all groups, demonstrating that CVD health disparities in the general population extend to cancer survivors. Despite the lower absolute mortalities, relative risks compared to their counterparts in the general population were greatest among API and Hispanic survivors, implying a greater impact of cancer diagnosis on the risk of CVD death among survivors of these populations. Targeted primary care and cardio-oncologic intervention strategies are needed to improve CVD outcomes and achieve cardiovascular health equity among cancer survivors.
