Background For adolescent and young adult (AYA) cancer patients aged 18 to 39 years, health insurance literacy is crucial for an effective use of the health care system. AYAs often face high out-of-pocket costs or have unmet health care needs due to costs. Improving health insurance literacy could help AYAs obtain appropriate and affordable health care. This protocol illustrates a randomized controlled trial testing a virtual health insurance education intervention among AYA patients. Methods This is a two-arm multisite randomized controlled trial. A total of 80 AYAs diagnosed with cancer in the Mountain West region will be allocated to either usual navigation care or tailored health insurance education intervention with a patient navigator that includes usual care. All participants will complete a baseline and follow-up survey 5 months apart. The primary outcomes are feasibility (number enrolled and number of sessions completed) and acceptability (5-point scale on survey measuring satisfaction of the intervention). The secondary outcomes are preliminary efficacy measured by the Health Insurance Literacy Measure and the COmprehensive Score for financial Toxicity. Discussion This trial makes a timely contribution to test the feasibility and acceptability of a virtual AYA-centered health insurance education program.

Although access to pediatric cancer care has implications for use of such care and patient outcomes, little is known about the geographic accessibility of pediatric cancer care and how it may vary by population characteristics across the continental US. To estimate the travel time to pediatric cancer care settings in the continental US, identify potential disparities among subgroups of children and adolescents and young adults (AYAs), and identify areas needing improved access to pediatric cancer care. This cross-sectional study collected data from August 1 to December 1, 2021. Pediatric oncologists' service locations in 2021 served as the pediatric cancer care settings, data for which were scraped from 2 websites containing information about health professionals. Demographic characteristics for younger children and AYAs aged 0 to 21 years were obtained from the 2015 to 2019 American Community Survey 5-year estimates. Data were analyzed from January 1 to April 31, 2022. The main outcome was the travel time from geographic centroids of zip code tabulation areas to the nearest pediatric oncologist. The median (IQR) travel times for each demographic subgroup were estimated. Per capita pediatric oncologist supply was calculated by dividing the total number of pediatric oncologists for each state or US Census division by its population. Of the 90 498 890 children and AYAs included in the study, 63.6% were estimated to travel less than 30 minutes and 19.7% to travel between 30 and 60 minutes (for a total of 83.3%) to the nearest pediatric oncologist. Median (IQR) travel times were longest for the American Indian or Alaska Native pediatric population (46 [16-104] minutes) and residents of rural areas (95 [68-135] minutes), areas with high deprivation levels (36 [13-72] minutes), and the South (24 [13-47] minutes) and Midwest (22 [11-51] minutes) compared with the general population of children and AYAs. The pediatric oncologist supply was lowest in Wyoming (0 oncologists per 100 000 pediatric population) and highest in Washington, DC (53.3 oncologists per 100 000 pediatric population). Pediatric oncologist supply across Census divisions was lowest in the Mountain division (3.3 oncologists per 100 000 pediatric population) and highest in the New England division (8.1 oncologists per 100 000 pediatric population). Results of this study showed that most children and AYAs in the continental US had adequate access to pediatric cancer care, although disparities existed among racial and ethnic groups and residents in rural areas, areas with high deprivation levels, and some Southern and Midwestern states. Reducing these disparities may require innovative approaches, such as expanding the capabilities of local facilities and creating partnerships with adult oncology centers and primary care physicians.

Background Emerging research suggests that survivors of childhood and adolescent cancers are at risk for morbidity and mortality associated with air pollutants. However, caregiver perceptions of the effects of air pollution are unknown. Thus, to address this gap we described caregivers’ perceptions of air pollution’s impact on general population health and specifically on childhood cancer survivors, and caregivers’ air pollution information-seeking and exposure reduction behaviors. Methods Participants were Utah residents, ≥18 years, and caregiver of a childhood cancer survivor who had completed treatment. Semi-structured interviews were conducted with caregivers to describe their perspectives on air quality, how air pollution impacts health (general population and survivor health), and their information seeking and exposure reduction behaviors. Interviews were recorded, transcribed, and analyzed through two rounds of structured coding. Results Caregivers ( N  = 13) were non-Hispanic white and primarily females (92.3%) between 30 and 49 years old (46.2%). Most families lived within the Wasatch Front (69.2%), the main metropolitan of Utah. Two categories emerged pertaining to caregiver’s perceptions of air pollution: 1) Limited awareness about the health effects of air pollution, and 2) Unsuccessful information seeking and minimal exposure reduction behaviors. All caregivers held negative perceptions of air pollution in Utah, but most were unaware of how pollution affects health. While some families limited air pollution exposure by avoiding outdoor activity or physically leaving the region, few practiced survivor-specific exposure reduction. Nearly half of caregivers worried about potential effects of air pollution on survivor health and wanted more information. Conclusions Despite negative perceptions of air pollution, caregivers were divided on whether air pollution could impact survivor health. Few caregivers engaged in exposure reduction for their cancer survivor. As air pollution levels increase in the U.S., continued research on this topic is essential to managing cancer survivor respiratory and cardiovascular health.

Cancer disparities in rural and frontier communities are an important issue in Utah because much of Utah is sparsely populated. The aims of this study were to investigate whether there are differences in the cancer incidence and 5‐year survival rates in Utah by metropolitan/rural residence and to investigate disparities in distributions of cancer risk factors. We used cancer registry records to identify patients diagnosed with a first primary cancer in Utah between 2004 and 2008. We estimated 5‐year survival and incidence rates. The Cox proportional hazards model was used to estimate hazard ratios (HRs) for the risk of death. There were 32,498 (86.9%) patients with cancer who lived in metropolitan counties and 4906 (13.1%) patients with cancer who lived in rural counties at the time of cancer diagnosis. Patients with cancer from rural counties were more likely to be older, American Indian/Alaskan Native, non‐Hispanic, male, and diagnosed at higher stage. Rural residents had a five‐year relative survival that was 5.2% lower than metropolitan residents and a 10% increase in risk of death (HR = 1.10, 95% CI = 1.03, 1.18) after adjustment for multiple factors. Overall, the cancer incidence rates in rural counties were lower by 11.9 per 100,000 per year (449.2 in rural counties vs. 461.1 in metropolitan counties). Cancer patients living in rural counties of Utah had different demographic characteristics as well as differences in incidence and survival rates. Further studies with individual‐level data are necessary to investigate the reasons behind these differences in cancer incidence and survival to reduce disparities. Cancer disparities in rural and frontier communities are an important issue in Utah because much of Utah is sparsely populated.

Background Childhood cancer survivors face increased risks of adverse cardiovascular outcomes due to treatment exposures. National guidelines recommend periodic cardiomyopathy screening for survivors exposed to anthracyclines or radiation. We examined the receipt of and the adherence to guideline‐recommended cardiomyopathy testing (echocardiogram, multigated acquisition scan, magnetic resonance imaging) among Medicaid‐enrolled childhood cancer survivors. Method Using data from the Childhood Cancer Survivor Study linked to administrative Medicaid claims, we analyzed 1062 at‐risk survivors aged 18–64 years who were continuously enrolled in Medicaid each year throughout 2015–2019. Results We found that 26.8% received any cardiomyopathy test, and 9.6% adhered to guidelines. Residence in Medicaid expansion (vs. non‐expansion) states was associated with 6.9% points (95% CI = 0.7–13.1) higher likelihood of receiving any cardiomyopathy test and 4.2% points (95% CI = 0.4–7.9) higher likelihood of adherence. Conclusions These findings suggest low receipt and poor adherence to guideline‐recommended cardiomyopathy screening among long‐term survivors of childhood cancer. Our data further underscore the critical role of Medicaid programs in supporting access to quality survivorship care for this vulnerable population.

Background Vaccinations are a vital part of routine childhood and adolescent preventive care. We sought to identify current oncology provider practices, barriers, and attitudes towards vaccinating childhood and adolescent cancer patients and survivors. Methods We conducted a one-time online survey distributed from March-October 2018 to pediatric oncologists at nine institutions across the United States ( N  = 111, 68.8% participation rate). The survey included 32 items about vaccination practices, barriers to post-treatment vaccination, availability of vaccinations in oncology clinic, familiarity with vaccine guidelines, and attitudes toward vaccination responsibilities. Descriptive statistics were calculated in STATA 14.2. Results Participants were 54.0% female and 82.9% white, with 12.6% specializing in Bone Marrow Transplants. Influenza was the most commonly resumed vaccine after treatment (7030%). About 50%-60% were familiar with vaccine guidelines for immunocompromised patients. More than half (62.7%) recommended that patients restart most immunizations 6 months to 1 year after chemotherapy. Common barriers to providers recommending vaccinations included not having previous vaccine records for patients (56.8%) or lacking time to ascertain which vaccines are needed (32.4%). Of participants, 66.7% stated that vaccination should be managed by primary care providers, but with guidance from oncologists. Conclusions Many pediatric oncologists report being unfamiliar with vaccine guidelines for immunocompromised patients and almost all report barriers in supporting patients regarding vaccines after cancer treatment. Our findings show that further research and interventions are needed to help bridge oncology care and primary care regarding immunizations after treatment.

Background Adherence to cancer screening is important for cancer survivors because they are at high risk of subsequent cancer diagnoses or recurrence. We assessed adherence to breast, cervical, and colorectal cancer‐(CRC)‐screening guidelines and evaluated demographic disparities among a population‐based sample of survivors. Methods A representative sample of Utah survivors diagnosed from 2012–2018 with any reportable invasive cancer was selected from central cancer registry records for a survey about survivorship needs. We estimated the proportion of eligible survivors adhering to U.S. Preventive Services Task Force screening guidelines and calculated risk ratios and 95% confidence intervals. Analyses were age‐adjusted and weighted to account for sample design and nonresponse. Results And 1421 survivors completed the survey (57.2% response rate). Screening adherence was 74.4% for breast, 69.4% for cervical, and 79.7% for CRC. Rural residents were more likely to adhere to breast cancer screening than urban residents (86.1% vs. 72.7%; adjusted RR = 1.19, CI = 1.05, 1.36). Higher educational attainment was associated with increased adherence to cervical and colorectal cancer screening. Younger age was associated with greater adherence to cervical cancer screening (p = 0.006) but lower adherence to CRC screening (p = 0.003). CRC screening adherence was lower among the uninsured and those without a primary care provider (45.6%) compared to those with a regular provider (83.0%; adjusted RR = 0.57, CI = 0.42, 0.79). Conclusions Surveys based on samples from central cancer registries can provide population estimates to inform cancer control. Findings demonstrate work is needed to ensure all Utah cancer survivors obtain recommended cancer screenings. Efforts should focus particularly on increasing uptake of breast and cervical cancer screening and reducing demographic disparities in CRC screening. Precis Despite high risk for subsequent cancer diagnosis, Utah cancer survivors are not all obtaining recommended breast, cervical, and colorectal cancer screenings. This presents a significant healthcare gap. In this paper, we examine adherence to breast, cervical, and colorectal cancer screening guidelines using a population‐based sample survey of cancer survivors in Utah. Our findings indicate additional work is needed to ensure all Utah cancer survivors obtain recommended cancer screenings and reduce demographic disparities in screening.

Background Lung cancer is the leading cause of cancer-related mortality in Utah despite having the nation’s lowest smoking rate. Radon exposure and differences in lung cancer incidence between nonmetropolitan and metropolitan areas may explain this phenomenon. We compared smoking-adjusted lung cancer incidence rates between nonmetropolitan and metropolitan counties by predicted indoor radon level, sex, and cancer stage. We also compared lung cancer incidence by county classification between Utah and all SEER sites. Methods SEER*Stat provided annual age-adjusted rates per 100,000 from 1991 to 2010 for each Utah county and all other SEER sites. County classification, stage, and sex were obtained from SEER*Stat. Smoking was obtained from Environmental Public Health Tracking estimates by Ortega et al. EPA provided low (< 2 pCi/L), moderate (2–4 pCi/L), and high (> 4 pCi/L) indoor radon levels for each county. Poisson models calculated overall, cancer stage, and sex-specific rates and p -values for smoking-adjusted and unadjusted models. LOESS smoothed trend lines compared incidence rates between Utah and all SEER sites by county classification. Results All metropolitan counties had moderate radon levels; 12 (63%) of the 19 nonmetropolitan counties had moderate predicted radon levels and 7 (37%) had high predicted radon levels. Lung cancer incidence rates were higher in nonmetropolitan counties than metropolitan counties (34.8 vs 29.7 per 100,000, respectively). Incidence of distant stage cancers was significantly higher in nonmetropolitan counties after controlling for smoking (16.7 vs 15.4, p  = 0.02*). Incidence rates in metropolitan, moderate radon and nonmetropolitan, moderate radon counties were similar. Nonmetropolitan, high radon counties had a significantly higher incidence of lung cancer compared to nonmetropolitan, moderate radon counties after adjustment for smoking (41.7 vs 29.2, p  < 0.0001*). Lung cancer incidence patterns in Utah were opposite of metropolitan/nonmetropolitan trends in other SEER sites. Conclusion Lung cancer incidence and distant stage incidence rates were consistently higher in nonmetropolitan Utah counties than metropolitan counties, suggesting that limited access to preventative screenings may play a role in this disparity. Smoking-adjusted incidence rates in nonmetropolitan, high radon counties were significantly higher than moderate radon counties, suggesting that radon was also major contributor to lung cancer in these regions. National studies should account for geographic and environmental factors when examining nonmetropolitan/metropolitan differences in lung cancer.

Background Endometrial cancer is the second most common cancer among female cancer survivors in the US and is increasing in incidence. Rural endometrial cancer patients experience lower survival rates but the reasons for the lower survival are not known. The aim of this study is to examine whether prognostic factors are different for rural and urban patients in a population-based cohort. Methods Endometrial cancer patients diagnosed 1997-2012 were identified through the Utah Cancer Registry and Utah Population Database. The address at cancer diagnosis was used to classify patients in rural or urban residences. Demographic and cancer-specific characteristics were examined as prognostic factors for both all-cause and endometrial cancer-specific mortality using Cox proportional hazards models. Results There were 2,994 endometrial cancer patients and 14.1% of these patients lived in rural areas at diagnosis. Rural endometrial cancer patients were older at cancer diagnosis and did not appear to be different in terms of obesity or overweight at cancer diagnosis. There were no differences for treatment or stage at diagnosis although rural patients had higher proportions of higher grade. Age at diagnosis, poverty, education, and histology were significant prognostic factors for all-cause death. Rural patients with more advanced stages of cancer had significantly increased risks of all-cause and endometrial cancer-specific death than urban patients. Rural endometrial cancer patients diagnosed at advanced stage had a 17-fold increase in the risk of all-cause death compared to an 8-fold increase in death for urban patients. Conclusions Rural endometrial cancer patients in Utah were older at diagnosis, had higher grade and higher comorbidities. While urban and rural endometrial cancer patients shared many prognostic factors, the risk of mortality is greater among rural patients with advanced stage endometrial cancer. Future studies should examine where patients are receiving treatment and how that impacts their survival and how to reduce the mortality rates of high risk patients.

Purpose Childhood cancer survivors are at higher risk of human papillomavirus (HPV)‐related second cancers than adolescents without cancer, yet their HPV vaccination uptake is lower. Using a statewide sample, we evaluated whether survivors are at higher risk of missed opportunities for concomitant HPV vaccination. Methods From statewide healthcare data, we identified encounters where vaccines were received. Concomitant HPV vaccine missed opportunities were defined as a vaccine encounter where the HPV vaccine was not administered, although eligibility criteria were met. From these encounters, our sample included 327 survivors identified from the Utah Cancer Registry, diagnosed 2000–2016 at ages 0–9, and a birth year and sex‐matched sample without cancer from the general population (n = 1,911). Mixed‐effects Poisson regression estimated the rate of concomitant missed opportunities per vaccine encounter and 95% confidence intervals by vaccine encounter type (all vaccines, flu shot only, or adolescent/catch‐up) from 2013 to 2016. Results Survivors had more concomitant HPV vaccine missed opportunities than the population sample (70.0% vs. 59.0%). On average, survivors were 12% more likely to have missed opportunities at vaccine encounters and 4% more likely at flu shot only encounters. The predicted excess risk of concomitant missed opportunities for survivors ranged from 0.5 per10 vaccine encounters to 1.1 per10 vaccine encounters. Higher parental education, rurality, younger first vaccine age, and chemotherapy were associated with missed opportunities. Conclusions Childhood cancer survivors have more missed opportunities for concomitant HPV vaccination than a population sample. As flu shots should be administered annually, providers have a regular opportunity to recommend and deliver the HPV vaccine to survivors. Childhood cancer survivors face a higher risk of HPV‐related cancers than adolescents without a cancer history; however, their vaccination rates tend to be lower. We assessed HPV vaccine missed opportunities among age‐eligible childhood cancer survivors and found significantly more missed opportunities for survivors than adolescents without a cancer history.
