Multilevel analysis in rural cancer control: A conceptual framework and methodological implications

Association of county-level provider density and social vulnerability with colorectal cancer-related mortality

BACKGROUND

Health care providers play a crucial role in increasing overall awareness, screening, and treatment of cancer, leading to reduced cancer mortality. We sought to characterize the impact of provider density on colorectal cancer population-level mortality.

METHODS

County-level provider data, obtained from the Area Health Resource File between 2016 and 2018, were used to calculate provider density per county. These data were merged with county-level colorectal cancer mortality 2016-2020 data from the Centers for Disease Control and Prevention. Multivariable regression was performed to define the association between provider density and colorectal cancer mortality.

RESULTS

Among 2,863 counties included in the analytic cohort, 1,132 (39.5%) and 1,731 (60.5%) counties were categorized as urban and rural, respectively. The colorectal cancer-related crude mortality rate was higher in counties with low provider density versus counties with moderate or high provider density (low = 22.9, moderate = 21.6, high = 19.3 per 100,000 individuals; P < .001). On multivariable analysis, the odds of colorectal cancer mortality were lower in counties with moderate and high provider density versus counties with low provider density (moderate odds ratio 0.97, 95% confidence interval 0.94-0.99; high odds ratio 0.88, 95% confidence interval 0.86-0.91). High provider density remained associated with a lower likelihood of colorectal cancer mortality independent of social vulnerability index (low social vulnerability index and high provider density: odds ratio 0.85, 95% confidence interval 0.81-0.89; high social vulnerability index and high provider density: odds ratio 0.93, 95% confidence interval 0.89-0.98).

CONCLUSION

Regardless of social vulnerability index, high county-level provider density was associated with lower colorectal cancer-related mortality. Efforts to increase access to health care providers may improve health care equity, as well as long-term cancer outcomes.

Relationship between area-level socioeconomic status and health-related quality of life among cancer survivors

Area-level socioeconomic status (SES) impacts cancer outcomes, such as stage at diagnosis, treatments received, and mortality. However, less is known about the relationship between area-level SES and health-related quality of life (HRQOL) for cancer survivors. To assess the additive value of area-level SES data and the relative contribution of area- and individual-level SES for estimating cancer survivors' HRQOL, we conducted a secondary analysis of data from a population-based survey study of cancer survivors (the Measuring Your Health [MY-Health] Study). Multilevel multinomial logistic regression models were used to examine the relationships between individual-level SES, area-level SES as measured by the Centers for Disease Control and Prevention's Social Vulnerability Index, and HRQOL group membership (high, average, low, or very low HRQOL). Area-level SES did not significantly increase model estimation accuracy compared to models using only individual-level SES. However, area-level SES could be an appropriate proxy when the individual-level SES is missing.

Understanding advanced practice registered nurse perspectives on providing care to people with a history of breast cancer

BACKGROUND

People with a history of breast cancer (PHBC) face a lifelong risk of treatment-related sequelae affecting their quality of life. Stakeholders advocate for improving breast cancer survivorship outcomes by increasing clinicians' knowledge of cancer survivorship issues. In Missouri, advanced practice registered nurses (APRNs) in nononcology settings provide routine survivorship care to PHBC; however, little is known about how they approach survivorship care planning for PHBC.

PURPOSE

Examine perspectives of Missouri APRNs practicing in nononcology settings about providing survivorship care to PHBC.

METHODS

A combination of grounded theory and thematic analysis techniques was used for focus groups and semistructured interviews. The interviews were audio-recorded, transcribed, and analyzed using grounded theory coding methods.

RESULTS

Nineteen nononcology Missouri-based APRNs (18 NPs, 1 CNS/DNP) shared their perspectives about managing care for PHBC. We identified four major themes. Our participants (1) attuned their baseline assessment techniques to a history of breast cancer; (2) were prepared to order additional evaluations; (3) were willing to proactively figure out next best steps for PHBC beyond theneed for breast cancer recurrence surveillance; and (4) suggest that streamlining cancer survivorship care resources would benefit both clinicians and PHBC.

CONCLUSIONS

Our findings shed light on how APRNs approach care planning for PHBC and the needs of nononcology APRNs for managing PHBC.

IMPLICATIONS FOR PRACTICE

Advanced practice registered nurses are well-positioned to improve cancer survivorship care. Increasing knowledge of cancer survivorship care guidelines could improve long-term health outcomes of PHBC. Access to cancer survivorship resources or experts via telehealth/technology for both APRNs and patients could improve survivorship care and overall health of PHBC.

Self-reported Racial Discrimination and Healthy Behaviors in Black Adults Residing in Rural Persistent Poverty Areas

BACKGROUND

Racism is a social determinant of health inequities and associated with poorer health and health behaviors. As a domain of racism, self-reported racial discrimination affects health through unhealthy behaviors (e.g., smoking) but the understudied impact of self-reported racial discrimination's relationship with healthy behaviors (e.g., cancer screening) precludes a comprehensive understanding of racism's impact on health inequities. Understanding how self-reported racial discrimination impacts healthy behaviors is even more important for those living in rural persistent poverty areas (poverty rates of 20% or more of a population since 1980), who have a higher disease burden due to poverty's interaction with racism. The distinct sociocultural context of rural persistent poverty areas may result in differential responses to self-reported racial discrimination compared to those in non-persistent poverty areas.

METHODS

A community-engaged process was used to administer a survey to a convenience sample of 251 Black adults residing in 11 rural persistent poverty counties in the state of Arkansas. Self-reported racial discrimination, fruit and vegetable intake, colorectal cancer screening, cervical cancer screening, and screening mammography were assessed. Stress and religion/spirituality were also assessed as potential mediators or moderators in the relationship between self-reported racial discrimination and healthy behaviors.

RESULTS

In adjusted models, those reporting more self-reported racial discrimination had a higher probability of having had a test to check for cervical cancer (situation discrimination: OR = 1.23, 95% CI: 1.04-1.5; frequency discrimination: OR = 1.06, 95% CI: 1.02-1.12). Stress and religion/spirituality were not significant mediators/moderators.

DISCUSSION

Greater self-reported racial discrimination was associated with a higher odds of cervical cancer screening. Black adults residing in rural persistent poverty areas may have greater self-reported racial discrimination-specific coping and racial identity attitudes.

Teleoncology: Novel Approaches for Improving Cancer Care in North America

Due to widespread healthcare workforce shortages, many patients living in remote and rural North America currently have reduced access to various medical specialists. These shortages, coupled with the aging North American population, highlight the need to transform contemporary healthcare delivery systems. The exchange of medical information via telecommunication technology, known as telemedicine, offers promising solutions to address the medical needs of an aging population and the increased demand for specialty medical services. This progressive movement has also improved access to quality health care by mitigating the current shortage of trained subspecialists. Minimizing the effects of these shortages is particularly urgent in the care of cancer patients, many of whom require regular follow-up and close monitoring. Cancer patients living in remote areas of North America have reduced access to specialized care and, thus, have unacceptably high mortality and morbidity rates. Teleoncology, or the use of telemedicine to provide oncology services remotely, has the ability to improve access to high-quality care and assist in alleviating the burden of some of the severe adverse events associated with cancer. In this review, the authors describe how recent advances in teleoncology can reduce healthcare disparities and improve future cancer care in North America.

Survival of Middle Eastern and North African Individuals Diagnosed with Colorectal Cancer: A Population-Based Study in California

BACKGROUND

Literature on colorectal cancer outcomes in individuals of Middle Eastern and North African (MENA) descent is limited. To address this gap, we estimated five-year colorectal cancer-specific survival by race and ethnicity, including MENA individuals, in a diverse, population-based sample in California.

METHODS

We identified adults (ages 18-79 years) diagnosed with a first or only colorectal cancer in 2004 to 2017 using the California Cancer Registry (CCR), including non-Hispanic White, non-Hispanic Black, non-Hispanic Asian, Hispanic, and MENA individuals. For each racial/ethnic group, we calculated five-year colorectal cancer-specific survival and used Cox proportional hazards regression models to examine the association of race/ethnicity and survival, adjusting for clinical and socio demographic factors.

RESULTS

Of 110,192 persons diagnosed with colorectal cancer, five-year colorectal cancer-specific survival was lowest in Black (61.0%) and highest in MENA (73.2%) individuals. Asian (72.2%) individuals had higher survival than White (70.0%) and Hispanic (68.2%) individuals. In adjusted analysis, MENA [adjusted HR (aHR), 0.82; 95% confidence interval (CI), 0.76-0.89], Asian (aHR, 0.86; 95% CI, 0.83-0.90), and Hispanic (aHR, 0.94; 95% CI, 0.91-0.97) race/ethnicity were associated with higher, and Black (aHR, 1.13; 95% CI, 1.09-1.18) race/ethnicity was associated with lower survival compared with non-Hispanic White race/ethnicity.

CONCLUSIONS

To our knowledge, this is the first study to report colorectal cancer survival in MENA individuals in the United States. We observed higher survival of MENA individuals compared with other racial/ethnic groups, adjusting for sociodemographic and clinical factors.

IMPACT

Future studies are needed to identify factors contributing to cancer outcomes in this unique population.

Aging in Rural Communities

Purpose of Review

Population aging is occurring worldwide, particularly in developed countries such as the United States (US). However, in the US, the population is aging more rapidly in rural areas than in urban areas. Healthy aging in rural areas presents unique challenges. Understanding and addressing those challenges is essential to ensure healthy aging and promote health equity across the lifespan and all geographies. This review aims to present findings and evaluate recent literature (2019-2022) on rural aging and highlight future directions and opportunities to improve population health in rural communities.

Recent Findings

The review first addresses several methodological considerations in measuring rurality, including the choice of measure used, the composition of each measure, and the limitations and drawbacks of each measure. Next, the review considers important concepts and context when describing what it means to be rural, including social, cultural, economic, and environmental conditions. The review assesses several key epidemiologic studies addressing rural-urban differences in population health among older adults. Health and social services in rural areas are then discussed in the context of healthy aging in rural areas. Racial and ethnic minorities, indigenous peoples, and informal caregivers are considered as special populations in the discussion of rural older adults and healthy aging. Lastly, the review provides evidence to support critical longitudinal, place-based research to promote healthy aging across the rural-urban divide is highlighted.

Summary

Policies, programs, and interventions to reduce rural-urban differences in population health and to promote health equity and healthy aging necessitate a context-specific approach. Considering the cultural context and root causes of rural-urban differences in population health and healthy aging is essential to support the real-world effectiveness of such programs, policies, and interventions.

Barriers and facilitators to early-stage lung cancer care in the USA: a qualitative study

PURPOSE

Improved outcomes in lung cancer treatment are seen in high-volume academic centers, making it important to understand barriers to accessing care at such institutions. Few qualitative studies examine the barriers and facilitators to early-stage lung cancer care at US academic institutions.

METHODS

Adult patients with suspected or diagnosed early-stage non-small cell lung cancer presenting to a multidisciplinary lung cancer clinic at a US academic institution over a 6-month period beginning in 2019 were purposively sampled for semi-structured interviews. Semi-structured interviews were conducted and a qualitative content analysis was performed using the framework method. Themes relating to barriers and facilitators to lung cancer care were identified through iterative team-based coding.

RESULTS

The 26 participants had a mean age of 62 years (SD: 8.4 years) and were majority female (62%), white (77%), and urban (85%). We identified 6 major themes: trust with providers and health systems are valued by patients; financial toxicity negatively influenced the diagnostic and treatment experience; social constraints magnified other barriers; patient self-advocacy as a facilitator of care access; provider advocacy could overcome other barriers; care coordination and good communication were important to patients.

CONCLUSIONS

We have identified several barriers and facilitators to lung cancer care at an academic center in the US. These factors need to be addressed to improve quality of care among lung cancer patients. Further work will examine our findings in a community setting to understand if our findings are generalizable to patients who do not access a tertiary cancer care center.

County-Level Social Vulnerability and Breast, Cervical, and Colorectal Cancer Screening Rates in the US, 2018

IMPORTANCE

Area-level factors have been identified as important social determinants of health (SDoH) that impact many health-related outcomes. Less is known about how the social vulnerability index (SVI), as a scalable composite score, can multidimensionally explain the population-based cancer screening program uptake at a county level.

OBJECTIVE

To examine the geographic variation of US Preventive Services Task Force (USPSTF)-recommended breast, cervical, and colorectal cancer screening rates and the association between county-level SVI and the 3 screening rates.

DESIGN, SETTING, AND PARTICIPANTS

This population-based cross-sectional study used county-level information from the Centers for Disease Control and Prevention's PLACES and SVI data sets from 2018 for 3141 US counties. Analyses were conducted from October 2021 to February 2022.

EXPOSURES

Social vulnerability index score categorized in quintiles.

MAIN OUTCOMES AND MEASURES

The main outcome was county-level rates of USPSTF guideline-concordant, up-to-date breast, cervical, and colorectal screenings. Odds ratios were calculated for each cancer screening by SVI quintile as unadjusted (only accounting for eligible population per county) or adjusted for urban-rural status, percentage of uninsured adults, and primary care physician rate per 100 000 residents.

RESULTS

Across 3141 counties, county-level cancer screening rates showed regional disparities ranging from 54.0% to 81.8% for breast cancer screening, from 69.9% to 89.7% for cervical cancer screening, and from 39.8% to 74.4% for colorectal cancer screening. The multivariable regression model showed that a higher SVI was significantly associated with lower odds of cancer screening, with the lowest odds in the highest SVI quintile. When comparing the highest quintile of SVI (SVI-Q5) with the lowest quintile of SVI (SVI-Q1), the unadjusted odds ratio was 0.86 (95% posterior credible interval [CrI], 0.84-0.87) for breast cancer screening, 0.80 (95% CrI, 0.79-0.81) for cervical cancer screening, and 0.72 (95% CrI, 0.71-0.73) for colorectal cancer screening. When fully adjusted, the odds ratio was 0.92 (95% CrI, 0.90-0.93) for breast cancer screening, 0.87 (95% CrI, 0.86-0.88) for cervical cancer screening, and 0.86 (95% CrI, 0.85-0.88) for colorectal cancer screening, showing slightly attenuated associations.

CONCLUSIONS AND RELEVANCE

In this cross-sectional study, regional disparities were found in cancer screening rates at a county level. Quantifying how SVI associates with each cancer screening rate could provide insight into the design and focus of future interventions targeting cancer prevention disparities.

Examination of risk factors for discontinuation of follow-up care in patients with head and neck cancer

BACKGROUND

Little research has examined discontinuation of follow-up care in patients with head and neck cancer. This exploratory study sought to examine key demographic, disease, and behavioral factors as possible correlates of discontinuation (N = 512).

METHODS

Cross-sectional study examined correlates of discontinuation of follow-up care within 1 year. The primary outcome was defined as a disease-free survivor not returning to cancer clinic for two consecutive follow-up appointments within the first year of care and not reentering oncologic care at any point thereafter. Demographic, disease, and behavioral factors were examined using multivariable logistic regression.

RESULTS

One hundred twenty-six (24.6%) patients discontinued by 12-month follow-up. Being unmarried (OR = 1.28, 95% CI = 1.01-1.63, p = 0.041) and having elevated depressive symptomatology (OR = 1.04, 95% CI = 1.01-1.07, p = 0.034) were significantly associated with discontinuation. Receipt of a single (vs. multimodal) treatment approached significance (OR = 1.71, 95% CI = 0.96-3.07, p = 0.071).

CONCLUSION

Approximately one quarter of patients disengaged from important follow-up care within 1 year. Lack of social support, depressive symptomatology, and single treatment modality may be important correlates of discontinuation of care in patients with head and neck cancer. Additional studies of this outcome are needed. Improved understanding of correlates associated with discontinuation could facilitate the identification of at-risk patients and further development of interventions to keep patients engaged at a crucial time in the survivorship care trajectory.

Geographic determinants of colorectal cancer in Louisiana

Purpose

Currently, rural residents in the United States (US) experience a greater cancer burden for tobacco-related cancers and cancers that can be prevented by screening. We aim to characterize geographic determinants of colorectal cancer (CRC) incidence in Louisiana due to rural residence and other known geographic risk factors, area socioeconomic status (SES), and cultural region (Acadian or French-speaking).

Methods

Primary colorectal cancer diagnosed among adults 30 years and older in 2008–2017 were obtained from the Louisiana Tumor Registry. Population and social and economic data were obtained from US Census American Community Survey. Rural areas were defined using US Department of Agriculture 2010 rural–urban commuting area codes. Estimates of relative risk (RR) were obtained from multilevel binomial regression models of incidence.

Results

The study population was 16.1% rural, 18.4% low SES, and 17.9% Acadian. Risk of CRC was greater among rural white residents (RR Women: 1.09(1.02–1.16), RR Men: 1.11(1.04–1.18)). Low SES was associated with increased CRC for all demographic groups, with excess risk ranging from 8% in Black men (RR: 1.08(1.01–1.16)) to 16% in white men (RR: 1.16(1.08–1.24)). Increased risk in the Acadian region was greatest for Black men (RR: 1.21(1.10–1.33)) and women (RR: 1.21(1.09–1.33)). Rural–urban disparities in CRC were no longer significant after controlling for SES and Acadian region.

Conclusion

SES remains a significant determinant of CRC disparities in Louisiana and may contribute to observed rural–urban disparities in the state. While the intersectionality of CRC risk factors is complex, we have confirmed a robust regional disparity for the Acadian region of Louisiana.

Characterizing head and neck cancer survivors' discontinuation of survivorship care

BACKGROUND

Little is known about cancer survivors who discontinue survivorship care. The objective of this study was to characterize patients with head and neck cancer who discontinue survivorship care with their treating institution and identify factors associated with discontinuation.

METHODS

This was a retrospective cohort study of patients diagnosed with head and neck cancer between January 1, 2014, and December 31, 2016, who received cancer-directed therapy at the University of Iowa Hospitals and Clinics (UIHC). Eligible patients achieved a cancer-free status after curative-intent treatment and made at least 1 visit 90+ days after treatment completion. The primary outcome was discontinuation of survivorship care, which was defined as a still living survivor who had not returned to a UIHC cancer clinic for twice the expected interval. Demographic and oncologic factors were examined to identify associations with discontinuation.

RESULTS

Ninety-seven of the 426 eligible patients (22.8%) discontinued survivorship care at UIHC during the study period. The mean time in follow-up for those who discontinued treatment was 15.4 months. Factors associated with discontinuation of care included an unmarried status (P = .036), a longer driving distance to the facility (P = .0031), and a single-modality cancer treatment (P < .0001). Rurality was not associated with discontinuation (24.3% vs 21.6% for urban residence; P = .52), nor was age, gender, or payor status.

CONCLUSIONS

The study results indicate that a sizeable percentage of head and neck cancer survivors discontinue care with their treating institution. Both demographic and oncologic factors were associated with discontinuation at the treating institution, and this points to potential clinical and care delivery interventions.

County-level characteristics associated with incidence, late-stage incidence, and mortality from screenable cancers

BACKGROUND

Cancer screening differs by rurality and racial residential segregation, but the relationship between these county-level characteristics is understudied. Understanding this relationship and its implications for cancer outcomes could inform interventions to decrease cancer disparities.

METHODS

We linked county-level information from national data sources: 2008-2012 cancer incidence, late-stage incidence, and mortality rates (for breast, cervical, and colorectal cancer) from U.S. Cancer Statistics and the National Death Index; metropolitan status from U.S. Department of Agriculture; residential segregation derived from American Community Survey; and prevalence of cancer screening from National Cancer Institute's Small Area Estimates. We used multivariable, sparse Poisson generalized linear mixed models to assess cancer incidence, late-stage incidence, and mortality rates by county-level characteristics, controlling for density of physicians and median household income.

RESULTS

Cancer incidence, late-stage incidence, and mortality rates were 6-18% lower in metropolitan counties for breast and colorectal cancer, and 2-4% lower in more segregated counties for breast and colorectal cancer. Generally, reductions in cancer associated with residential segregation were limited to non-metropolitan counties. Cancer incidence, late-stage incidence, and mortality rates were associated with screening, with rates for corresponding cancers that were 2-9% higher in areas with more breast and colorectal screening, but 2-15% lower in areas with more cervical screening.

DISCUSSION

Lower cancer burden was observed in counties that were metropolitan and more segregated. Effect modification was observed by metropolitan status and county-level residential segregation, indicating that residential segregation may impact healthcare access differently in different county types. Additional studies are needed to inform interventions to reduce county-level disparities in cancer incidence, late-stage incidence, and mortality.

Comparative Analysis of Rural-Urban Definitions in Predicting Surgeon Workforce Supply

BACKGROUND

There are multiple different systems that define a rural area in health services research, but few studies compare their ability to measure access to health resources. Our objective was to compare various definitions of rurality to determine which system best measures local surgeon supply.

MATERIALS AND METHODS

In this retrospective observational study, we used the 2019 Area Health Resource File to obtain the 2017 county-level supply of general surgeons, surgical subspecialists, and total physicians for all counties in the United States. Physicians per 100,000 population were calculated for each physician measure and were the primary outcomes. The rural-urban measurements included were the Office of Management and Budget 2017 definition, Urban Influence Codes (UIC), Rural-Urban Commuting Codes (RUCCs), and Census urban population within the county. We also developed and tested a measure combining the RUCCs and Census urban population. Linear regression was used to compare performance of these definitions for each outcome using adjusted R² values.

RESULTS

In 3138 counties included in the study, dichotomous measures of rural-urban using the UIC/RUCC had the lowest adjusted R² values across all outcomes. Quartiles using the Census urban population and the RUCC/Census urban population combined measure had the highest adjusted R² values for all outcomes.

CONCLUSIONS

The Census urban population had the best performance in measuring geographic access to surgical care. This study can inform surgical health services researchers who want to include measures of rurality in their analysis.

Spatial analysis of colorectal cancer outcomes and socioeconomic factors in Virginia

BACKGROUND

Colorectal cancer (CRC) disparities vary by country and population group, but often have spatial features. This study of the United States state of Virginia assessed CRC outcomes, and identified demographic, socioeconomic and healthcare access contributors to CRC disparities.

METHODS

County- and city-level cross-sectional data for 2011-2015 CRC incidence, mortality, and mortality-incidence ratio (MIR) were analyzed for geographically determined clusters (hotspots and cold spots) and their correlates. Spatial regression examined predictors including proportion of African American (AA) residents, rural-urban status, socioeconomic (SES) index, CRC screening rate, and densities of primary care providers (PCP) and gastroenterologists. Stationarity, which assesses spatial equality, was examined with geographically weighted regression.

RESULTS

For incidence, one CRC hotspot and two cold spots were identified, including one large hotspot for MIR in southwest Virginia. In the spatial distribution of mortality, no clusters were found. Rurality and AA population were most associated with incidence. SES index, rurality, and PCP density were associated with spatial distribution of mortality. SES index and rurality were associated with MIR. Local coefficients indicated stronger associations of predictor variables in the southwestern region.

CONCLUSIONS

Rurality, low SES, and racial distribution were important predictors of CRC incidence, mortality, and MIR. Regions with concentrations of one or more factors of disparities face additional hurdles to improving CRC outcomes. A large cluster of high MIR in southwest Virginia region requires further investigation to improve early cancer detection and support survivorship. Spatial analysis can identify high-disparity populations and be used to inform targeted cancer control programming.

Rural Cancer Disparities: Understanding Implications for Breast and Cervical Cancer Diagnoses

BACKGROUND

Rural populations experience several disparities, influenced by structural-, community-, and individual-level barriers, across the breast and cervical cancer continuum.

OBJECTIVES

This study seeks to identify structural-, community-, and individual-level barriers that affect rural populations across the cancer continuum, understand the role of nurses serving rural populations in breast and cervical cancer screening and diagnostics, and provide recommendations for working with rural patients.

METHODS

This is a secondary analysis of qualitative interviews conducted with public health nurses serving rural populations.

FINDINGS

Emergent themes indicate that rural populations experience barriers that affect disparities across the breast and cervical cancer continuum, including a changing healthcare landscape, access to cancer-focused care, access to insurance, collective poverty, and demographic factors. Nurses working with rural communities can address these disparities as they fulfill multiple roles and responsibilities.

A retrospective cohort study of cutaneous squamous cell carcinoma of the scalp: features of disease and influence of sociodemographic factors on outcomes

BACKGROUND

Cutaneous squamous cell carcinoma (SCC) is an increasingly prevalent and potentially fatal disease with considerable implications if not recognized early and treated promptly. Several disease features contribute to a higher risk profile and adverse outcomes in affected patients.

AIMS

Given the clinical observation that elderly males from rural communities often present with large SCCs of the scalp, we sought to investigate and describe features of disease and sociodemographic factors from a cohort of patients with scalp SCCs.

METHODS

Histology reports of scalp primary SCCs were retrospectively assessed. Disease and demographic features were recorded. Descriptive statistics were generated, and statistical analyses (Fisher's exact, Mann-Whitney U and Spearman's rank test) were utilized to examine relationships between high-risk disease features and sociodemographic features.

RESULTS

Ninety-three occurrences of scalp SCC in 61 patients were assessed. The average age at presentation was 78.81 years. Males were predominantly affected at a 14:1 ratio. Half of all tumours were greater than 2 cm (47/93 (50.54%)). The geographical distance from treatment was significantly associated with larger tumours at presentation. (r_s = .34 P = 0.002). Recurrence and metastasis rates were determined amongst 188 patients with a primary scalp SCC, and low rates were observed (2.66% and 2.13%, respectively).

CONCLUSIONS

Elderly males are inordinately affected by scalp SCC compared to females. Those living further from care exhibited larger tumours at presentation. Data from this study characterize features of SCC of the scalp and provide evidence to suggest that rural isolation may act as a mediator of high-risk presentation and larger tumour size.

Cancer genetic testing in marginalized groups during an era of evolving healthcare reform

BACKGROUND

The Affordable Care Act and subsequent reforms pose tradeoffs for racial-ethnic, rural, and sex-related groups in the United States experiencing disparities in BRCA1/2 genetic counseling and testing and colorectal cancer screening, calling for policy changes.

METHODS

A working group of the American Public Health Association Genomics Forum Policy Committee engaged in monthly meetings to examine ongoing literature and identify policy alternatives in the coverage of cancer genetic services for marginalized groups. 589 items were collected; 408 examined. Efforts continued from February 2015 through September 2020.

RESULTS

African Americans and Latinos have shown 7-8 % drops in uninsured rates since the Exchanges opened. The ACA has increased BRCA1/2 test availability while several disparities remain, including by sex. Rural testing and screening utilization rates have improved. Medicaid expansion and the inclusion of Medicare in the ACA have resulted in mixed improvements in colorectal cancer screening rates in marginalized groups.

CONCLUSION

Cancer genetic testing and screening to date have only partially benefited from healthcare reforms. Sensitivity to cost concerns and further monitoring of emerging data are needed. A reduction in disparities depends on the availability of private insurance, Medicaid and Medicare to the marginalized. Attention to value-based design and the way cancer benefits are translated into actual testing and screening are crucial.

POLICY SUMMARY

The findings suggest the need for further benefits-related health agency interpretation of and amendments to the ACA, continued Medicaid and innovative Medicare expansion, and incorporation of cancer services values-based considerations at several levels, aimed at reducing group disparities.

The Intersection of Rural Residence and Minority Race/Ethnicity in Cancer Disparities in the United States

One in every twenty-five persons in America is a racial/ethnic minority who lives in a rural area. Our objective was to summarize how racism and, subsequently, the social determinants of health disproportionately affect rural racial/ethnic minority populations, provide a review of the cancer disparities experienced by rural racial/ethnic minority groups, and recommend policy, research, and intervention approaches to reduce these disparities. We found that rural Black and American Indian/Alaska Native populations experience greater poverty and lack of access to care, which expose them to greater risk of developing cancer and experiencing poorer cancer outcomes in treatment and ultimately survival. There is a critical need for additional research to understand the disparities experienced by all rural racial/ethnic minority populations. We propose that policies aim to increase access to care and healthcare resources for these communities. Further, that observational and interventional research should more effectively address the intersections of rurality and race/ethnicity through reduced structural and interpersonal biases in cancer care, increased data access, more research on newer cancer screening and treatment modalities, and continued intervention and implementation research to understand how evidence-based practices can most effectively reduce disparities among these populations.
