Introduction
Adolescent and young adult cancer patients (AYAs; diagnosed between the ages of 15-39 years) are particularly vulnerable to financial toxicity (FT), which includes the psychological (e.g., increased anxiety or stress), material (e.g., increased debt, housing or food insecurity, or loss of income or employment), and behavioral aspects (e.g., delaying or forgoing treatment or follow-up care) of financial hardship.1,2 AYAs are especially susceptible to FT due to the critical developmental life stages that increase their financial responsibilities, such as entering higher-education and/or the workforce, experiencing long-term and late effects of cancer treatment, and healthcare transitions (HCTs) from pediatric and/or specialty oncology care to adult and/or primary follow-up care.3,4 Unique social determinants of health that impact racial/ethnic minorities, as well as rural residents, such as limited access to quality healthcare, cultural and/or language barriers, low socioeconomic status and educational attainment, heighten their vulnerability to FT and its associated negative health and financial outcomes. 5
Despite the significant medical needs stemming from the late and long-term effects of their original cancer, many AYA cancer survivors face barriers to participating in cancer-related follow-up care. 6 Poor HCTs can result in serious medical, psychological and financial repercussions, such as reduced treatment adherence, healthcare utilization, and higher hospitalization rates. 7 HCTs are especially challenging for AYA cancer survivors due to a variety of factors, including patient-related issues (e.g., psychosocial functioning, financial barriers, knowledge gaps, and self-efficacy),8-10 provider-related challenges (e.g., insufficient knowledge and training)11,12 and system-related obstacles (e.g., lack of appointment coordination or navigation support). 9 Race and rurality further complicate these transitions, as systemic inequalities often result in limited access to specialized care, lower health literacy, and greater geographic barriers to consistent treatment. Given these complex factors, AYA cancer survivors, particularly racial minorities and rural residents represent a critical target population for interventions aimed at promoting successful HCTs, maintaining engagement in adult/primary healthcare systems, and enhancing overall quality of life (QOL). 13
Although research in the field is expanding, racial and geographic disparities in FT remain poorly defined.4,8 The lack of comprehensive research on how these disparities specifically impact AYA cancer survivors underscores critical gaps in understanding the intersection of race, rurality, and social determinants of health in these vulnerable populations. 13 To address these gaps, we examined racial (Black vs White) and geographic (rural vs urban) disparities in FT and HCTs among AYA cancer survivors using data from the Kentucky Cancer Registry. We hypothesized that survivors who identify as Black and/or reside in rural regions will be more likely to experience greater FT and have poorer HCT outcomes compared to survivors who identify as White and/or reside in urban regions. Kentucky leads the nation in both cancer incidence and mortality across cancer sites with Black residents face a notably higher cancer mortality rate compared to both White residents and the overall state population, especially in breast, colorectal, prostate, liver, myeloma, endometrial and uterus cancers. 14 From 2010 to 2019, approximately 7621 White and 531 Black AYAs in Kentucky were diagnosed with cancer, with the most common primary sites being blood and bone, breast, thyroid, testis, and skin.
Methods
Study Design, Setting and Sample
We used a cross-sectional survey design, guided by the Social-ecological Model of AYA Readiness for Transition (SMART). 8 AYA cancer survivors residing in Kentucky were recruited from February 2022 to February 2023 through the population-based Kentucky Cancer Registry (KCR) using established recruitment procedures. 15 Recruitment began after the KCR team identified survivors who matched our inclusion criteria: (1) initial cancer diagnosis between the ages of 15 and 39, (2) 18 years or older at the time of recruitment, (3) residing in Kentucky, (4) able to read and write in English. The KCR used purposive sampling to identify a representative sample of cancer survivors categorized by Black and White race and rural and urban geographic regions. Letters were sent to 800 eligible cancer survivors notifying them of their eligibility for the study and requesting consent to release their contact information for research purposes. A total of 376 survivors agreed to be contacted; 200 completed online REDCap (Research Electronic Data Capture) surveys and 60 completed mailed surveys (surveys were identical). Along with obtaining written consent to gather and analyze survey data, participants also agreed to the release of their individual, record-level data from KCR. This study received approval from the University of Kentucky Institutional Review Board (#74682). The reporting of this study conforms to STROBE guidelines. 16
Data Collection
Participant-specific characteristics were obtained from individual KCR records, including sex, date of birth, race/ethnicity, county of residence, date of diagnosis, and age since diagnosis. County of residence was categorized as urban or rural using the 2013 rural-urban continuum codes 17 ; counties with codes from 1 to 3 were considered urban, while those in the 4-9 range were scored as rural. Participants filled out a descriptive survey that covered topics such as their education, income, health insurance coverage, employment status, marital status, and household size, which was used to assess their federal poverty level (FPL). Household income was categorized based on the 2024 FPL guidelines published by the U.S. Department of Health and Human Services.
Financial toxicity was measured as a total score and 3 subscores corresponding with each domain: 1) psychological response, 2) material conditions and 3) coping behaviors. 18 Psychological response was measured using the 11-item FACIT-COST (Comprehensive Score for Financial Toxicity; Cronbach α = .92). 18 To assess material conditions of FT, four items from the Medical Expenditure Panel Survey Experiences with Cancer Survey (MEPS-ECS) 19 were utilized to determine if participants had borrowed money or went into debt, filed for bankruptcy, unable to cover share of medical care costs, or made other financial sacrifices because of cancer. Coping behaviors were assessed using a single item from the MEPS-ECS, which asked whether participants had delayed, skipped, or made other changes to any of the following cancer care such as medications, specialist visits, treatment, follow-up care, or mental health services due to costs. A total FT score was created using the 3 domain scores with a reverse-coded COST-FACIT to give the psychological response domain the same polarity as the other FT measures where higher scores indicate greater financial toxicity. 20 These tools and scoring mechanisms have been used in previous studies.15,20,21
Healthcare Transitions outcomes were measured using 3 survey tools assessing four sets of variables: 1) transition readiness, 2) number of medical issues experienced by the participant, 3) follow-up care for cancer, and 4) health-related QOL. Transition readiness was measured using the 18-item Self-Management in Adulthood with Rx = Treatment (STARx) questionnaire, a validated (Cronbach α = .80) tool, focusing on three key areas: communication with providers, disease knowledge, and self-management. 22 Information on medical issues and follow up care were collected using a 39-item checklist on late/long-term effects of cancer treatment from the NCI’s Follow-Up Care Use and Health Outcomes of Cancer Survivors (FOCUS) Survey. 23 Tools from the Patient-Reported Outcomes Measurement Information System (PROMIS) including the 10-item Global Health measure, 24 the 4-item Anxiety Short Form (Cronbach α = .98), 25 and the 6-item Depression Short Form (Cronbach α = .98). 26 Scoring for PROMIS was performed using HealthMeasures, with standardized t scores applied for analysis. Higher scores on PROMIS Global Health indicate greater quality of life and higher scores on PROMIS Anxiety and Depression indicate greater severity of anxiety and depression.
Data Analysis
Survey data were downloaded from REDCap directly into SAS 27 and summarized using descriptive statistics, including means, standard deviations, and ranges or frequency distributions (n, %). Bivariate analyses were conducted to examine the associations amongst indicators of FT, and indicators of HCTs with Black and White as well as rural and urban participants using two-sample t-tests. Bivariate analyses between indicators of FT and indicators of HCTs were assessed using simple linear regression with estimated slopes and standard errors as well as the P-value assessing whether the slope was significantly different from zero. Finally, two-way ANCOVA modeling was used to assess whether associations between FT indicators (predictor variable) and HCT indicators (outcome) differed between the two sociodemographic variables of interest (race and rurality). The two-way interaction between the FT indicator and either race or rurality were used to test the hypothesis of whether the HCT/FT associations differed by race or rurality. This is essentially a test of whether race or rurality are effect modifiers. Separate two-way ANCOVAs were fitted for the unique FT variable and race as well as FT variable and rurality combinations. Hypothesis testing was conducted using a Type I error rate for each comparison made of 5%. All analyses were conducted using SAS. 27 We have deidentified all patient details in this report. An a priori power analysis was conducted using nQuery Advisor (v. 8) to ensure sufficient statistical power. With a sample size of 180, and at least 25% Black participants, the power of the two-sample t-test to detect a medium effect size was estimated to be at least 82%. With a sample of at least 180 subjects, up to 10 predictors, and an alpha level of .05, the power of the multiple linear regression F test to detect R2 as small as 0.1 was estimated to be at least 87%.

Descriptive Summary of Demographics and Clinical Variables for Total Sample
Note: Household income was categorized based on the 2024 FPL guidelines published by the U.S. Department of Health and Human Services.
Financial Toxicity
The reversed COST-FACIT mean score was 18.8 (±7.60, range: 0 to 44; higher scores indicate greater FT), with a material conditions mean score of 1.7 (±1.34, range: 0 to 5), a coping behavior mean score of 0.9 (±1.66, range: 0 to 9). The total FT mean score was 0.26 (±0.11, range: 0.04 to 0.59) (see Table 1). Regarding household income, 47% indicated they were “getting by” with 21% reporting ‘finding it difficult or very difficult’. 31% indicated that they had gone into debt because of cancer treatment.
Healthcare Transitions
The mean transition readiness score was 60.2 (±12.9, range: 14 to 80) (see Table 1 for domain scores). The average number of medical issues reported was 1.8 (±2.26, range: 0 to 13) with nearly 87% of study participants reported having sought follow-up care for cancer at some point in time, 79% within the last two years. The global health mean score was 27.3 (±8.73, range: 9 to 52) with a mean anxiety score of 56.3 (±9.38, range: 40.3 to 81.6), and a mean depression score of 53.1 (±10.07, range: 38.4 to 80.3).

In all four models with transition readiness as the outcome, neither race nor any of the 4 FT variables (total FT, COST-FACIT, material conditions and coping behaviors) were significantly associated. For the number of medical issues, total FT (P < 0.0001), coping behavior (P = 0.0159), and material conditions (P < 0.0001) scores were significantly associated adjusting for race.
In the models with global health as the outcome, total FT and material conditions scores were significantly associated with the outcome when race was included in the models. The mean total FT score in Blacks (M = 29.1, SE = 1.01) differed (P = 0.0364) from Whites (M = 26.6, SE = 0.60) with each unit increase in the total FT score resulting in a 30.3 unit increase in the global health score (β = 30.3) (P < 0.0001). Similarly, the mean material conditions score in Blacks (M = 29.0, SE = 1.00) differed (P = 0.0464) from Whites (M = 26.6, SE = 0.59) (β = 2.5). The model that contained race and COST-FACIT revealed a race difference (P = 0.0154) but not a COST-FACIT association (P = 0.9189). Similarly, the model with race and coping behavior indicated an association of global health scores with coping behavior (P < 0.0001) but not race (P = 0.0745).
The models for anxiety showed a significant (P < 0.0001) increase in anxiety for each unit increase in total FT (β = 24.4, SE = 5.38), coping behavior (β = 1.5, SE = 0.35) and material conditions (β = 2.2, SE = 0.43) scores when adjusting for race. The only significant race difference was observed with the model involving reversed COST-FACIT and race. The mean anxiety score in Blacks was estimated to be 58.4 (SE = 1.20) and in Whites was 55.6 (SE = 0.70; P = 0.0441).
For the depression outcome, there were no significant differences in race in any of the 4 models, but the total FT (β = 17.7, SE = 5.94, P = 0.0031), coping behavior (β = 1.3, SE = 0.38, P = 0.0005) and the material conditions (β = 1.8, SE = 0.47, P = 0.0002) scores were all positively associated with this outcome adjusting for race.

Discussion
The purpose of this study was to examine racial (Black vs White) and geographic (rural vs urban) disparities in FT and HCTs among AYA cancer survivors. Our sample of 260 AYAs from the Kentucky Cancer Registry was composed of 73% participants who identified as White and 27% as Black, 75% were urban residents, and 60% reported an annual income at or above $50,000. To put this into the context of Kentucky’s broader population, the state is composed of approximately 87% White residents and 9% Black residents, more than half of the state population resides in urban areas, and the median annual household income in 2023 was $62,417.28,29 Our sample had moderate COST-FACIT, coping behavior and material conditions scores. They also had moderate transition readiness scores, experienced fewer long/late term effects of treatment, and had higher rates of seeking cancer-related follow-up care compared to similar samples in existing studies. Strong and positive associations were found between total FT scores and long/late term effects of treatment, global health, anxiety and depression. Our findings that higher FT levels were associated with higher rates of long/late term effects of treatment, anxiety, and depression strengthens existing literature, which links high FT with decreased treatment compliance
30
and diminished QOL.
31
Similarly, our sample bolstered evidence from previous studies with the finding that higher levels of depression and anxiety were associated with higher material conditions and coping behavior scores.
32
When adjusting for race, our findings showed significant associations between FT, coping behaviors, and material conditions to global health, anxiety, and depression (Figure 1). These associations further reinforce previous findings5,8 that FT may impact patient outcomes, particularly levels of psychological distress. Main Findings
The sampled AYA cancer survivors experienced moderate levels of FT and transition readiness, and had higher levels of healthcare utilization/follow up care. These outcomes contradict previous studies that have documented high levels of FT 33 and low transition readiness, and healthcare utilization among AYAs. 34 This discrepancy may be influenced by factors such as time since diagnosis, suggesting that financial burden may decrease as survivors move further away from their initial treatment. Another potential explanation for these findings may be related to the sample’s relatively higher level of education and employment as previous studies have associated low educational attainment and income with an increase in financial burden.35,36 Participants in this study indicated self-reported difficulties with living on their current income and going into debt due to cancer treatment, which reflects and compounds upon established evidence of the material hardship experienced by AYAs in other studies. 37 The discrepancies between our sampled participant responses and existing literature underscores the need for future research with larger samples to better consider these variables in relation to subsets of age groups and time since diagnosis. Such an approach may provide a more nuanced understanding of the FT experienced by AYA cancer survivors and further delineate its relationship with HCTs. Our study highlights the importance of ongoing efforts to address the diverse needs of AYA cancer survivors across different contexts.
Our study found that Black participants demonstrated higher anxiety levels and increased reliance upon coping behaviors compared to White participants, even after adjusting for FT. These findings align and add to prior research demonstrating greater QOL disparities among Black cancer survivors (i.e., increased psychological distress, reduced healthcare access, and social isolation).38,39 These disparities often lead to the use of negative coping habits like treatment avoidance or disengagement, which may worsen the emotional and financial burdens they may already be experiencing. 40 The racial disparities expanded upon here stem from structural inequities surrounding access to care, income levels, and insurance coverage.1,2,41,42 Our findings highlight the need for tailored interventions targeted at improving access to care with a focus on reducing anxiety and other psychological impacts of FT.
Beyond the finding that urban residing participants had higher material conditions scores when compared to rural counterparts, our study did not find significant differences in FT and HCT outcomes between rural and urban AYA cancer survivors. However, these findings should be interpreted with caution, as they may be influenced by limitations in our study’s sampling of rural residents. Existing literature highlights rural disparities in cancer care compliance, 43 FT experience, 44 and psychosocial outcomes 45 necessitating tailored interventions in these areas. 46 Cancer centers should remain cognizant of unique FT experiences such as limited healthcare infrastructure, access barriers, and lower cost-related health literacy 36 of rural AYA cancer survivors in the design and implementation of financial navigation efforts.
Our study findings show the need for targeted interventions focused on mitigating the impact of FT on underserved AYA cancer survivors. Oncology financial navigation is one evidence-based approach that has demonstrated reductions in FT among cancer patients.20,47 Financial navigators help patients and caregivers navigate the costs of cancer care by ensuring they have access to appropriate health insurance coverage and connect individuals to financial assistance programs.20,21 While not established as standard of care, financial navigation services have been incorporated across cancer centers in the U.S. Barriers to implementing navigation services include lack of funding and other resources, which could be a driving implementation factor in under resourced cancer centers serving vulnerable populations. Additional research is needed on tailoring financial navigation interventions to expand their reach and accessibility in racially diverse and rural populations.
Limitations
Findings from our study should be interpreted with caution due to limitations in sampling. Our sample was limited in number of Black and rural residing participants, which may have influenced our multivariate analyses. Race was limited to Black and White groups due to constraints related to recruiting other racial/ethnic groups from the KCR. The inclusion of only English-speaking participants for our study was an additional limitation reducing generalizability of our findings to non-English speaking populations. Use of cross-sectional design and lack of longitudinal data limits understanding of FT among AYAs across the trajectory of their cancer experience and at corresponding developmental milestones. Most of our sample had higher levels of education, income, and insurance coverage, which limits our understanding of FT experiences among underserved cancer survivors. Despite these limitations, recruitment via KCR provided us the most comprehensive access to Black and rural-residing cancer survivors, offering an unparalleled opportunity to capture a relatively diverse racial and geographically diverse sample.
Conclusions
Our study highlights the connection between FT, HCTs, and racial and geographic disparities faced by AYA cancer survivors. We found that Black participants experienced higher anxiety and relied more on coping strategies compared to White participants, while urban residents had better material conditions than those in rural areas. Although FT was associated with anxiety, depression, and long-term treatment effects, these associations did not differ by race or location. These findings emphasize the need to address financial barriers to care, and by considering race and geography, we may gain clearer insights into how social determinants of health impact QOL and HCTs. Future research should focus on designing and implementing culturally tailored interventions for Black and rural communities to address gaps in existing literature. Implementing financial and legal navigation services could help reduce FT and improve access to care, which may ultimately enhance health outcomes for AYA cancer survivors.
