Cancer mortality in the United States by education level and race

Sociodemographic, medical, health behavior, and psychosocial factors associated with COVID-19 diagnoses in the New Jersey cancer survivor cohort

BACKGROUND

Cancer survivors are more susceptible to contracting COVID-19. However, beyond race, age, and sex, less is known about other neighborhood and psychosocial factors contribute to this increased risk.

OBJECTIVE

The goal of this study was to examine the associations of individual and area-level social determinants of health (SDOH) measures, medical, lifestyle, and psychosocial factors and COVID-19 infection in a statewide cohort of cancer survivors in New Jersey.

METHODS

Survey data from 864 cancer survivors in New Jersey were collected from 2018 to 2022, which were merged with study participant data from the state of New Jersey on COVID-19 diagnoses in 2020, 2021, and 2022. We estimated adjusted odds ratios (aOR) for associations of COVID-19 diagnosis with individual-level factors (cancer type and stage, health behaviors, and psychosocial factors) and area-level SDOH [Social Vulnerability Index, Area Deprivation Index, and Index of Concentration at the Extremes (ICE) to quantify racialized deprivation vs. privilege based on income].

RESULTS

Cancer survivors born outside the US were more than twice as likely to contract COVID-19 compared to US-born survivors (aOR 2.29, 95% CI 1.01, 4.92). Compared to Quartile 4, residence in an area in Quartile 1 of racialized income ICE (i.e., predominantly Black, low income) was associated with higher odds of COVID-19 (aOR 2.15, 95% CI 0.98, 4.87). Retired survivors had lower odds of COVID-19 (aOR 0.39, 95% CI 0.19, 0.80) compared to those who were employed. Higher social well-being was associated with higher COVID-19 (aOR 1.07, 95% CI 1.02, 1.13). Type of cancer and cancer treatments received were not associated with the risk of COVID-19.

CONCLUSIONS

Immigrant status and increased racialized deprivation as measured by ICE for income were associated with COVID-19. These findings support evidence that individual and area-level SDOH measures contribute to increased risk of COVID-19 among cancer survivors.

Disparities in Palliative Treatment Utilization in Metastatic Colorectal Cancer Patients

INTRODUCTION

Patients with metastatic colorectal cancer (mCRC) often require multidisciplinary interventions due to the diversity of symptoms. Palliative treatment offers benefits including improved quality of life, yet sociodemographic disparities influence its utilization. This study aims to characterize these disparities in palliative treatment use among mCRC patients.

METHODS

Utilizing data from the National Cancer Database, we identified patients diagnosed with mCRC between 2016 and 2020. Patients were categorized by metastatic site: peritoneal, liver, lung, or bone/brain/lymph node. Palliative treatment rates were compared across metastatic sites as well as patient and hospital factors.

RESULTS

A total of 106,241 patients were identified as having mCRC, with 19,208 (18.08%) receiving palliative treatment; 24.0% of patients with multiple metastatic disease and 14.0% of those with solely peritoneal metastases (PM) utilized palliative treatment (p < 0.001). Furthermore, patients over 75 years of age had a significantly decreased likelihood of receiving palliative treatment compared with younger patients (p = 0.0002). Hispanic patients did not differ significantly from non-Hispanic White populations (p = 0.47). Those in the highest education quartile demonstrated a higher degree of palliative treatment use compared with the lowest education quartile (p = 0.0081).

CONCLUSION

Among patients with mCRC, those with multiple sites of metastatic disease tend to receive higher rates of palliative treatment compared with those with oligometastatic disease. Patients with PM had the lowest rate of receiving palliative treatment. Other determinates of utilizing palliative treatment include younger age groups and higher education. Further research is warranted to understand the patterns of disparities in palliative treatment use among mCRC patients.

NCRP Claims Six Studies Support LNT But They Show No-Effect to At Least 100 mGy

NCRP Commentary-27 reaffirmed Linear No Threshold (LNT) as the basis for radiation protection and listed six studies with "strong support" for LNT. This paper looks critically at these six studies and shows that they do not support LNT in the dose range of 0-100 mGy. These studies typically admit to no increase in cancer risk at significant dose levels. More importantly this paper shows that these studies assume LNT from the outset, underestimate uncertainty, ignore confounding factors, have biased control groups, and underestimate dose.

Socioeconomic status and its association with outcome in patients with Cushing's disease

OBJECTIVE

Cushing's disease (CD) is associated with severely impaired quality of life and shortened life expectancy. Little is known about the socioeconomic consequences of CD and their impact on long-term outcome.

METHODS

This was a nationwide study including 371 patients with CD (76% women), diagnosed between 1991 and 2018, and 4 matched controls per patient from the background population. Clinical data were retrieved from the national Swedish pituitary register and socioeconomic data were collected from national Swedish registers from up to 20 years before and up to 20 years after diagnosis.

RESULTS

The proportion of patients receiving disability pensions was increased, starting 6 years before diagnosis, and increased further thereafter, mainly due to mental and musculoskeletal disorders, to reach around 20%-25% during long-term follow-up. Low educational level in patients with CD was associated with lower rates of employment and increased mortality (adjusted hazard ratio 2.5, 95% CI 1.1-5.4).

CONCLUSIONS

CD is associated with low socioeconomic status that is already noticeable 6 years before diagnosis and remains high during follow-up. Low socioeconomic status, in particular low educational level, is associated with adverse outcome. The findings indicate a need for proactive rehabilitation plans as part of standard management.

Population attributable fraction of dietary risk factors for cancer mortality with a focus on gastrointestinal cancers in a population based cohort study

Diet and nutrition are critical factors influencing cancer, the second leading cause of death worldwide. This study evaluated dietary risk factors and cancer mortality. 49,773 participants aged 40-75 years from the Golestan Cohort Study (GCS) were followed for a median of 15 years. Dietary intake was assessed using a validated food frequency questionnaire. Cox proportional hazard models estimated hazard ratios (HRs) and 95% confidence intervals (CIs), while population attributable fractions (PAFs) quantified the impact of reducing dietary risk factors. Low fruit intake accounted for 4.7% (95% CI: 0.5-8.7%) of all cancer deaths and 4.91% (95% CI: 0-9.85%) of male cancer deaths. It contributed to 23.5% (95% CI: 4.7-38.59%) of pancreatic cancer mortality in both sexes and 29.36% (95% CI: 5.15-47.38%) of male pancreatic cancer deaths. Low omega-3 intake increased esophageal and gastric cancer mortality risks, with PAFs of 21.65% (95% CI: 1.14-37.9%) and 21.46% (95% CI: 2.81-36.53%), respectively. In females, low omega-3 intake accounted for 38.68% (95% CI: 4.05-60.81%) of gastric cancer deaths. Low fruit and omega-3 consumption elevated cancer mortality risk. Community- and individual-level interventions are essential to enhance nutrient intake and reduce cancer mortality.

Mutational disparities in colorectal cancers of White Americans, Alabama African Americans, And Oklahoma American Indians

The high incidence and mortality rates of colorectal cancer (CRC) in Alabama African Americans (AAs) and Oklahoma American Indians (AIs) are recognized as cancer disparities, yet the underlying causes have been poorly demonstrated. By evaluating CRC whole-exome sequencing and mutational profiles, here we report sets of mutated genes whose frequencies differed significantly (p < 0.05) in a race-specific manner. Secondary screening with cancer database identified "survival-critical genes (SCGs)" (i.e., genes whose mutations/alterations are associated with significant differences in the patients' survival rates) among the differentially mutated genes. Notable SCGs with race-pronounced variants were different from DEGs and their involved pathways included nucleotide catabolism and cell cycle checkpoints for AAs, and extracellular matrix organization for AIs. The inclusion of these SCGs with race-pronounced variants in the clinical CRC next-generation sequencing panels and the development of targeting drugs will serve as refinements for precision medicine to overcome racial disparities in health outcomes of CRC.

Introduction of Cancer Education Program in Secondary School Curriculum: Perceptions of Education Teachers and Policymakers in Oman

The prevalence of cancer is expected to increase worldwide for reasons related to a lack of awareness of cancer prevention, diagnosis, and treatment. Implementing cancer education programs in schools in the developing countries with similar demographic, economic, and health transition to that of Oman is crucial for enhancing students' cancer knowledge and promoting healthy behavior. This study aims to explore the perceptions of education, policymakers, and teachers regarding the inclusion of cancer education in secondary school curriculum. The study employed a qualitative method, conducting semi-structured interviews with ten education policymakers and ten school teachers. Interviews were audio recorded, transcribed, and analyzed verbatim and qualitatively using the framework approach. Three main themes have emerged: (1) perception of the importance of cancer education inclusion within the school curriculum, (2) the perception of cancer education implementation in schools, and (3) the perceived challenges of introducing cancer education in schools. Policymakers and teachers in Oman recognize the importance of cancer education in schools and emphasized the need to prioritize it due to the increasing prevalence of the disease and the belief that negative lifestyle habits played a role in its increased prevalence. Implementing cancer education programs in schools is essential in improving students' knowledge of cancer and health behaviors. Collaboration between the department of school health in ministry of education and in ministry of health and incorporating cancer education into different school activities can be beneficial. However, the perceived challenges of cancer education in schools include the decision on the priority of cancer education among other topics, the required procedures to introduce cancer education in schools, and the financial and logistics obligations of implementing cancer education programs. Therefore, addressing the financial and logistic requirements is essential to overcome the associated challenges for implementing cancer education programs within the school curriculum.

Health Disparities and Inequities in the Utilization of Proton Therapy for Prostate Cancer

Our study sought to review and summarize the reported health disparities and inequities in the utilization of proton beam therapy (PBT) for prostate cancer. We queried the PubMed search engine through 12/2023 for original publications examining disparate utilization of PBT for prostate cancer. The query terms included the following: prostate cancer AND proton AND (disparities OR IMRT OR race OR insurance OR socioeconomic OR inequities)". Studies were included if they involved United States patients, examined PBT in prostate cancer, and addressed health inequities. From this query, 22 studies met the inclusion criteria, comprising 13 population-based analyses, 5 single-institutional analyses, 3 cost/modeling investigations, and 1 survey-based study. The analyses revealed that in addition to age-related and insurance-related disparities, race and socioeconomic status played significant roles in the receipt of PBT. The likelihood of receiving PBT was lower for non-White patients in population-based and single-institution analyses. Socioeconomic metrics, such as higher median income and higher education level, portended an increased likelihood of receiving PBT. Conclusively, substantial age-based, racial, socioeconomic/insurance-related, and facility-associated disparities and inequities existed for PBT utilization in prostate cancer. The identification of these disparities provides a framework to better address these as the utility of PBT continues to expand across the US and globally.

Analysing premature cardiovascular disease mortality in the United States by obesity status and educational attainment

BACKGROUND

In the United States (US), premature cardiovascular disease (CVD) mortality rates (35-74 years) have exhibited increases in recent years, particularly in younger adults, and large differentials by educational attainment. This trend has occurred concurrently with high and increasing obesity prevalence, which also show significant differences by education. This study aims to jointly model premature CVD mortality trends in the US according to obesity status and educational attainment.

METHODS

We used multiple cause of death data from the National Center for Health Statistics, obesity prevalence data from the National Health and Nutrition Examination Survey (NHANES), and educational attainment data from the American Community Survey and NHANES. We applied Bayes' theorem to these data to calculate the conditional probability of premature CVD mortality given obesity status and educational attainment for 2003-2019. We then projected this conditional probability for 2020-2029 using the Lee-Carter model.

RESULTS

The probability of premature CVD mortality was greatest for obesity and low education (not graduated high school) and was substantially higher (females 6.7 times higher, males 5.9) compared with non-obesity and high education (Bachelor's degree or higher) in 2019. There was a widening of the gap in premature CVD mortality from 2003 to 2019 between the obese and non-obese populations, which occurred at each education level and was projected to continue in 2020-2029, especially for males. The conditional probability of premature CVD death for obesity and middle education (finished high school but no Bachelor's degree) increased substantially and was projected to surpass the level for non-obesity and low education in coming years for males and in younger age groups. At high education, the conditional probability of premature CVD death for the obese population was projected to increase to 2029, while for non-obesity it was projected to remain steady for females and fall for males; this projected widening is greatest at older age groups.

CONCLUSIONS

The findings demonstrate the public health challenge to reduce premature US CVD mortality posed by continued high obesity prevalence, especially for younger ages, lower education groups and males. The relative importance of obesity in influencing premature CVD mortality trends has risen partly due to the decline in CVD mortality attributable to other risk factors.

Contrasting income-based inequalities in incidence and mortality of breast cancer in Korea, 2006-2015

OBJECTIVES

Breast cancer incidence and mortality rates in Korea are increasing. This study analyzed income-based inequalities in the incidence and mortality of women breast cancer from 2006 to 2015, using national data that covered all Korean women.

METHODS

We used the National Health Information Database from 2006 to 2015. For women aged 20 and older, the age-standardized incidence and mortality rates of breast cancer per 100,000 by income quintile per year were calculated using the direct method. The rate ratio and rate difference (RD) of the age-standardized incidence and mortality rates of breast cancer per 100,000 between the top and bottom income quintiles were calculated as relative and absolute measures for inequalities.

RESULTS

When comparing 2006 and 2015, both the incidence and mortality rates of breast cancer increased. The lowest income quintile experienced higher mortality rates despite having lower incidence rates. In 2015, the income-based RD in incidence and mortality rates between the highest and lowest income quintiles (Q1-Q5) was -19.9 (95% confidence interval [CI], -24.3 to -15.5) and 4.4 (95% CI, 2.9 to 5.8), respectively. Throughout this period, there was no statistically significant trend in income-based disparities in breast cancer incidence and mortality. The age-specific contributions to the absolute magnitude of inequality (RD) in incidence and mortality were more pronounced among middle-aged women than among older women.

CONCLUSIONS

This study found that breast cancer in Korea exhibited pro-rich inequalities in mortality despite pro-poor inequalities in incidence. More equitable policies for screening and treatment of breast cancer are needed.

Demographic differences in early vs. late-stage laryngeal squamous cell carcinoma

PURPOSE

This study aims to evaluate how various demographic factors impact the stage at diagnosis and, therefore, prognosis of laryngeal cancer.

MATERIALS AND METHODS

Using the National Cancer Database, 96,409 patients were diagnosed with laryngeal squamous cell carcinoma between 2004 and 2020. Early (stage 0 or I) vs. late-stage (stage IV) cancers were compared based on demographic variables utilizing Chi-square and multivariate analysis with a significance of p < 0.05.

RESULTS

Female, Black, and generally older patients were more likely to have late-stage cancer than their counterparts. When compared with a community cancer program, patients treated at other facility types were more likely to be diagnosed late. Patients with private insurance, Medicare, or other government insurance were all less likely to have late-stage cancer compared to patients without insurance. Compared to patients in the lowest median household income quartile, patients in the third quartile and fourth quartile were diagnosed earlier. Patients living in an area with the lowest level of high school degree attainment were most likely to be diagnosed late. Living in a more populous area was associated with a lower chance of being diagnosed late. Increasing Charlson-Deyo Score was associated with a stronger likelihood of being diagnosed at a later stage.

CONCLUSION

Patients who are female, Black, uninsured, have a low household income, live in less populated and less educated areas, are treated at non-community cancer programs, and have more comorbid conditions have later stage diagnoses. This data contributes to understanding inequities in healthcare.

The effects of racial and socioeconomic disparities on time to diagnosis and treatment of pediatric functional seizures in the United States

PURPOSE

The present study sought to assess the effects of racial and socioeconomic status in the United States on time to treatment and diagnosis of pediatric functional seizures (FS).

METHODS

Eighty adolescents and their parent/guardian completed a demographics questionnaire and reported date of FS onset, diagnosis, and treatment. Paired samples t-tests compared time between FS onset and diagnosis, onset and treatment, and diagnosis and treatment based on race (White vs racial minority), annual household income (≤$79,999 vs ≥$80,000), maternal and paternal education (≤Associate's Degree vs Bachelor's Degree), and combined parental education (≤Post-graduate training vs Graduate degree).

RESULTS

Adolescents with lower annual household income began treatment >6 months later than adolescents with greater annual household income (p = 0.049). Adolescents with lower maternal and paternal education (≤Associate's Degree vs Bachelor's Degree) began treatment >4 and ∼8.5 months later than adolescents with greater maternal and paternal education (p = 0.04; p = 0.03), respectively. Adolescents with lower maternal education also received a diagnosis >5 months later (p = 0.03). Adolescents without a mother or father with a graduate degree received a diagnosis and began treatment∼3 and >11 months later (p = 0.03; p = 0.01) than adolescents whose mother or father received a graduate degree, respectively. No racial differences were found.

CONCLUSIONS

Adolescents with lower annual household income and/or parental education experienced increased duration between FS onset and treatment and diagnosis. Research is needed to clarify the mechanisms underlying this relationship, and action is needed to reduce these disparities given FS duration is associated with poorer prognosis and greater effects on the brain.

Comparing acceptance of smoking cessation and smoke-free home intervention offers and associated factors among people with low income in the USA: baseline results of a randomised controlled trial

Introduction

State tobacco quitlines are the most commonly available smoking cessation programmes; however, they have low reach and typically only enrol people who are ready to quit in the next 30 days. Expanding quitline services may increase the total number of people engaged in tobacco control efforts and the number who eventually quit. In this randomised controlled trial, we offered both arms a tobacco quitline intervention. In arm 2, if they declined the quitline, we then offered a smoke-free home (SFH) intervention. We examined the number of participants who accepted each intervention offer at baseline and whether acceptance varied by participant characteristics.

Methods

We recruited 1982 people who called 211, a social services helpline for social needs; mean age=50, 68% female; 45% white, 41% black and 14% other race/ethnicity; 68% reported an annual household income

Results

In each arm, 59.7% of participants accepted the quitline offer. In arm 2, among those who declined the quitline offer, 53.1% accepted the SFH intervention offer. Thus, an additional 212 (21.4% of all arm 2 participants) people who smoke engaged in tobacco control programmes than would have with standard practice alone (quitline only). Acceptance differed by participant characteristics: males were less likely than females to accept either offer. Whites were less likely, and older adults and those with greater nicotine dependence were more likely, to accept the quitline offer.

Conclusions

Proactive approaches identified many low-income people who smoke and offering an SFH intervention retained many more of them in tobacco control efforts. Future trial results will assess intervention engagement and effects on cessation.

Equity in oncology care: addressing disparities in cancer treatment in Georgia

This research delves into the disparities in access to oncology care among cancer patients in Georgia, with a specific focus on the distinct challenges faced by African American (AA) individuals compared to non-African American (Non-AA) counterparts. Leveraging data from the 2020 Behavioral Risk Factor Surveillance System (BRFSS) survey and supplementary online resources, the study meticulously examines socioeconomic factors, including income, education, and insurance coverage, which significantly influence the quality of cancer care received. The analysis reveals substantial income gaps between AA and Non-AA patients, underscoring the critical implications for healthcare access. Moreover, AA patients exhibit lower rates of full insurance coverage for cancer-related treatments, posing additional barriers to comprehensive care. By investigating the intersections of race, income, and education, the research aims to pinpoint the root causes of these disparities and proposes evidence-based solutions to address the identified challenges. The ultimate objective is to contribute valuable insights that inform targeted policy recommendations and community-based interventions, fostering a more equitable landscape for oncology care in Georgia. This study seeks to amplify awareness and advocate for tangible measures, striving toward healthcare equity for all cancer patients, irrespective of their racial or socioeconomic backgrounds.

Potential Risks for Healthcare Disparities Among Individuals With Voice and Upper Airway Disorders: A Systematic Review

PURPOSE

To assess the potential epidemiological association between various possible risk factors and healthcare disparities specifically related to the access, use and/or quality of speech language pathology services for individuals with voice and upper airway disorders.

METHOD

A systematic review was conducted using the Preferred Reporting Items for Systematic Review and Meta-Analysis. Full text journal articles were identified through PubMed, PsycINFO and Web of Science. The reference sections of included articles were also manually screened and identified four additional studies for consideration of inclusion. Included articles specifically addressed healthcare disparities in voice and upper airway disorders related to speech pathology care. International literature was excluded. Eligible studies were reviewed and data extracted. Risk of bias of each eligible study was performed using the quality assessment tool from National Institute of Health for observational cohort and cross-sectional studies. Data from eligible studies were synthesized thematically.

RESULTS

A total of 1,101 resources were retrieved from the search; of these, 133 were duplicates. Titles and abstracts of 968 articles were screened, with 14 selected for full-text review. Eleven articles were considered eligible for inclusion. Voice disorders were the condition most frequently examined followed by only one article addressing upper airways disorders. There was considerable heterogeneity in the methodology and statistical analyses among the eligible papers. There was a lack of standard methodology for collecting and accurately determining patient characteristics as well as variability in measuring confounding variables and providing statistical analyses for such adjustments that may have impacted the findings. The information extracted from these articles revealed healthcare disparities related to sex/gender, age, insurance status/coverage, race/ethnicity, among others including etiology and preferred language.

CONCLUSIONS

This systematic review highlights the limited research on speech language pathology-specific healthcare disparities for individuals with voice and upper airway disorders. There was significant clinical and methodological heterogeneity between studies which may have contributed to varied results between studies. There is a need for greater methodological rigor and prospectively designed studies to better characterize the impact of disparities in the access to, use of, and quality of speech pathology care for this patient population.

Impact of socioeconomic disparities on outcomes in adults undergoing allogeneic hematopoietic cell transplantation for acute myeloid leukemia

Racial and socioeconomic disparities impact outcomes after chemotherapy and limit access to allogeneic hematopoietic cell transplantation (HCT) in acute myeloid leukemia (AML), yet studies have yielded mixed results on the influence of disparities on post-HCT outcomes. Therefore, we studied 1024 adults with AML who underwent allogeneic HCT between 5/2006 and 10/2021 at a single large university-affiliated cancer center. Collected data included non-biologic and demographic characteristics (including race/ethnicity, marital status, distance traveled, and household size), transplant- and disease-related characteristics, and area-level and individual-level socioeconomic factors (i.e., area deprivation index and occupational status). After multivariable adjustment, no socioeconomic- or non-biologic factors were associated with non-relapse mortality (NRM), overall survival (OS), relapse-free survival (RFS), or relapse except being married (associated with improved NRM: hazard ratio [HR] = 0.7 [0.50-0.97]) and having no insurance (associated with worse OS: HR = 1.49 [1.05-2.12] and RFS: HR = 1.41 [1.00-1.98]). Despite a relatively racially homogenous cohort, Asian race was associated with improved NRM (HR = 0.47 [0.23-0.93]) and American Indian/Alaskan Native race was associated with higher relapse risk (HR = 2.45 [1.08-5.53]). In conclusion, in our retrospective analysis, socioeconomic-, demographic-, and non-biologic factors had limited impact on post-HCT outcomes in AML patients allografted in morphologic remission. Further research is needed to investigate disparities among HCT-eligible patients.

Association of socioeconomic status and overactive bladder in US adults: a cross-sectional analysis of nationally representative data

Background

Socioeconomic status inequality is an important variable in the emergence of urological diseases in humans. This study set out to investigate the association between the prevalence of overactive bladder (OAB) and the poverty income ratio (PIR) that served as a more influential indicator of socioeconomic status compared to education and occupation.

Method

Data from the National Health and Nutrition Examination Survey (NHANES) conducted from 2007 to 2020 were used in this cross-sectional study. The association between the PIR and OAB was examined using weighted multivariate logistic regression and weighted restricted cubic splines (RCS). Additionally, interaction analysis was used for investigation to the connections between PIR and OAB in various covariate groups in order to confirm the stability of the results.

Results

We observed a noteworthy inverse association between PIR and OAB after adjusting for potential confounding variables (OR = 0.87, 95% CI, 0.84-0.90, p < 0.0001). PIR was transformed into categorical variables, and the association held steady after that (1.0 < PIR <4.0 vs. PIR ≤ 1.0, OR = 0.70, 95% CI =0.63-0.77, p < 0.0001; PIR ≥ 4.0 vs. PIR ≤ 1.0, OR = 0.56, 95% CI =0.48-0.65, p < 0.0001). Additionally, RCS analysis showed that PIR and OAB had a negative nonlinear response relationship. Subgroup analyses showed that the inverse association between PIR and prevalence of OAB was stronger in obese than in nonobese individuals (P for interaction < 0.05).

Conclusion

In our study, we observed a significant negative association between the PIR and the prevalence of OAB. In the future, PIR could be used as a reference standard to develop strategies to prevent and treat OAB.

Breast Cancer Disparity and Outcomes in Underserved Women

Women in the United States who continue to face obstacles accessing health care are frequently termed an underserved population. Safety-net health care systems play a crucial role in mitigating health disparities and reducing burdens of disease, such as breast cancer, for underserved women. Disparities in health care are driven by various factors, including race and ethnicity, as well as socioeconomic factors that affect education, employment, housing, insurance status, and access to health care. Underserved women are more likely to be uninsured or underinsured throughout their lifetimes. Hence they have greater difficulty gaining access to breast cancer screening and are less likely to undergo supplemental imaging when needed. Therefore, underserved women often experience significant delays in the diagnosis and treatment of breast cancer, leading to higher mortality rates. Addressing disparities requires a multifaceted approach, with formal care coordination to help at-risk women navigate through screening, diagnosis, and treatment. Mobile mammography units and community outreach programs can be leveraged to increase community access and engagement, as well as improve health literacy with educational initiatives. Radiology-community partnerships, comprised of imaging practices partnered with local businesses, faith-based organizations, homeless shelters, and public service departments, are essential to establish culturally competent breast imaging care, with the goal of equitable access to early diagnosis and contemporary treatment.

Social disparities in sleep health of African populations: A systematic review and meta-analysis of observational studies

OBJECTIVES

To document the relationship between socioeconomic status (SES) and sleep health in African populations.

METHODS

Observational cross-sectional or cohort studies examining the association between SES indicators and sleep outcomes in participants from African countries were included. The search was performed in the MEDLINE, Embase, and Web of Science Core Collection electronic databases in June 2021. Selection, confounding, attrition/exclusion, detection, and selective reporting bias were assessed using the OHAT Risk of Bias Tool. Random effects meta-analysis was used for summarizing the effect estimates.

RESULTS

Forty-three reports were selected, having sampled 153,372 Africans from 26 countries. Education was the most frequent SES indicator and composite measures of sleep quality or disturbances was the most common sleep outcome. Low educational attainment was significantly associated with lower odds of short sleep (odds ratio [OR]=0.65, 95% confidence intervals [0.50, 0.84], p = .001) and higher odds of insomnia (OR=1.53, [1.18, 1.99], p = .001) or poor sleep quality (OR=1.60, [1.17, 2.18], p = .003). Low levels of income/assets were related to higher odds of insomnia (OR=1.38, [1.02, 1.86], p = .04) and low occupational/employment status was linked to lower odds of short sleep duration (OR=0.49, [0.30, 0.79], p = .004).

CONCLUSIONS

Socioeconomic disadvantage was a significant predictor of insomnia and poor sleep quality, while it was associated with longer sleep duration. Significant heterogeneity in terms of exposure and outcomes, scarcity of longitudinal designs, lack of objective outcome measurement, and low representation of rural samples and participants from low-income countries limit the quality of evidence.

Association of educational attainment with cancer mortality in a national cohort study of black and white adults: A mediation analysis

Background

Low educational attainment is associated with excess cancer mortality. However, the mechanisms driving this association remain unknown.

Methods

Using data from the REasons for Geographic and Racial Differences in Stroke (REGARDS) study, we evaluated the associations of participant and parental/caregiver education with cancer mortality using Cox proportional hazards models, adjusting for socio-demographic characteristics and health conditions. We used principal components analysis to generate indices of measures representing the social determinants of health (SDOH) and health behaviors. We used structural equation modeling to determine if the association between educational attainment and cancer mortality was mediated by these domains.

Results

Among 30,177 REGARDS participants included in this analysis, 3798 (12.6%) had less than a high school degree. In fully adjusted models, those without a high school education experienced about 50% greater risk of death than high school graduates and higher (White participants HR: 1.47; 95% CI: 1.23, 1.76 and Black HR: 1.54; 95% CI: 1.33, 1.79). There was evidence of a modest mediation effect for the association between education and cancer mortality by the SDOH domain score (White total effect HR: 1.25; 95% CI: 1.18, 1.33, indirect effect HR: 1.04; 95% CI: 1.03, 1.05, direct effect HR: 1.21; 95% CI: 1.14, 1.28 and Black total effect HR: 1.24; 95% CI: 1.18, 1.29, indirect effect HR: 1.04; 95% CI: 1.03, 1.05, direct effect HR: 1.19; 95% CI: 1.14, 1.24). There was no evidence of mediation by the health behaviors score. No significant associations were found for female caregiver/mother's or male caregiver/father's education (N = 13,209).

Conclusions

In conclusion, participant education was strongly associated with cancer mortality, and this association was partially mediated by the SDOH domain score.

Educational Attainment and Cancer Incidence in a Large Nationwide Prospective Cohort

BACKGROUND

Educational attainment is a social determinant of health and frequently used as an indicator of socioeconomic status. Educational attainment is a predictor of cancer mortality, but associations with site-specific cancer incidence are variable. The aim of this study was to evaluate the association of educational attainment and site-specific cancer incidence adjusting for known risk factors in a large prospective cohort.

METHODS

Men and women enrolled in the American Cancer Society's Cancer Prevention Study-II Nutrition Cohort who were cancer free at baseline were included in this study (n = 148,965). Between 1992 and 2017, 22,810 men and 17,556 women were diagnosed with incident cancer. Cox proportional hazards regression models were used to estimate age- and multivariable-adjusted risk and 95% confidence intervals of total and site-specific cancer incidence in persons with lower versus higher educational attainment.

RESULTS

Educational attainment was inversely associated with age-adjusted cancer incidence among men but not women. For specific cancer sites, the multivariable-adjusted risk of cancer in the least versus most educated individuals remained significant for colon, rectum, and lung cancer among men and lung and breast cancer among women.

CONCLUSIONS

Educational attainment is associated with overall and site-specific cancer risk though adjusting for cancer risk factors attenuates the association for most cancer sites.

IMPACT

This study provides further evidence that educational attainment is an important social determinant of cancer but that its effects are driven by associated behavioral risk factors suggesting that targeting interventions toward those with lower educational attainment is an important policy consideration.

Disparities in survival of hematologic malignancies in the context of social determinants of health: a systematic review

Social determinants of health (SDHs) have been reported as relevant factors responsible for health inequity. We sought to assess clinical data from observational studies conducted in the United States evaluating the impact of SDHs on the outcomes of patients with hematologic malignancies. Thus, we performed a systematic review in 6 databases on 1 September 2021, in which paired reviewers independently screened studies and included data from 41 studies. We assessed the risk of bias using the Joanna Briggs Institute appraisal tools and analyzed the data using a descriptive synthesis. The most common SDH domains explored were health care access and quality (54.3%) and economic stability (25.6%); others investigated were education (19%) and social and community context (7.8%). We identified strong evidence of 5 variables significantly affecting survival: lack of health insurance coverage or having Medicare or Medicaid insurance, receiving cancer treatment at a nonacademic facility, low household income, low education level, and being unmarried. In contrast, the reports on the effect of distance traveled to the treatment center are contradictory. Other SDHs examined were facility volume, provider expertise, poverty, and employment rates. We identified a lack of data in the literature in terms of transportation, debt, higher education, diet, social integration, environmental factors, or stress. Our results underscore the complex nature of social, financial, and health care barriers as intercorrelated variables. Therefore, the management of hematologic malignancies needs concerted efforts to incorporate SDHs into clinical care, research, and public health policies, identifying and addressing the barriers at a patient-based level to enhance outcome equity (PROSPERO CRD42022346854).

Social Determinants of Health in Imaging-based Cancer Screening: A Case-based Primer with Strategies for Care Improvement

Health disparities, preventable differences in the burden of disease and disease outcomes often experienced by socially disadvantaged populations, can be found in nearly all areas of radiology, including emergency radiology, neuroradiology, nuclear medicine, image-guided interventions, and imaging-based cancer screening. Disparities in imaging-based cancer screening are especially noteworthy given the far-reaching population health impact. The social determinants of health (SDoH) play an important role in disparities in cancer screening and outcomes. Through improved understanding of how SDoH can drive differences in health outcomes in radiology, radiologists can effectively provide patient-centered, high-quality, and equitable care. Radiologists and radiology practices can become active partners in efforts to assist patients along their imaging journey and overcome existing barriers to equitable cancer screening care for traditionally marginalized populations. As radiology exists at the intersection of diagnostic imaging, image-guided diagnostic intervention, and image-guided treatment, radiologists are uniquely positioned to design these strategies. Cost-effective and socially conscious strategies that address barriers to equitable care can improve both public health and equitable health outcomes. Potential strategies include championing supportive health policy, reducing out-of-pocket costs, increasing price transparency, improving education and outreach efforts, ensuring that appropriate language translation services are available, providing individualized assistance with appointment scheduling, and offering transportation assistance and childcare. ©RSNA, 2023 Quiz questions for this article are available in the supplemental material.

Correlations between Demographic, Clinical, and Paraclinical Variables and Outcomes in Patients with KRAS-Mutant or KRAS Wild-Type Metastatic Colorectal Cancer-A Retrospective Study from a Tertiary-Level Center in Romania

Colorectal cancer (CRC) is a significant global public health concern and its characteristics in Eastern Europe are underexplored. In this retrospective study, data of 225 patients with metastatic colorectal cancer (mCRC) from the Colțea Clinical Hospital's Oncology Department in Bucharest were analyzed between 2015 and 2023. They were divided into two groups based on the presence of KRAS mutation. The primary objective of the study was to investigate whether the presence of KRAS mutations influenced the prognosis of mCRC and to identify any demographic, clinical, or paraclinical factors associated with KRAS mutations in stage IV CRC. The overall survival for the entire study population was 29 months. There was a trend towards increased survival in the KRAS wild-type group (31 months) compared to the KRAS-mutant group (26 months), but this difference did not reach statistical significance. We found that lower levels of education, advanced T stage, advanced N stage, and M1 stage at diagnosis negatively impacted prognosis. Real-world data are crucial in shaping public policy strategies to better support patients with metastatic CRC. Understanding the correlations between the demographic, clinical, and paraclinical variables and the outcomes in mCRC patients with KRAS-mutant and KRAS wild-type colorectal cancer is essential for improving patient care and treatment strategies in Romania and beyond.

Molecular disparities in colorectal cancers of White Americans, Alabama African Americans, and Oklahoma American Indians

In the US, the majority of cancer samples analyzed are from white people, leading to biases in racial and ethnic treatment outcomes. Colorectal cancer (CRC) incidence and mortality rates are high in Alabama African Americans (AAs) and Oklahoma American Indians (AIs). We hypothesized that differences between racial groups may partially explain these disparities. Thus, we compared transcriptomic profiles of CRCs of Alabama AAs, Oklahoma AIs, and white people from both states. Compared to CRCs of white people, CRCs of AAs showed (a) higher expression of cytokines and vesicle trafficking toward modulated antitumor-immune activity, and (b) lower expression of the ID1/BMP/SMAD axis, IL22RA1, APOBEC3, and Mucins; and AIs had (c) higher expression of PTGS2/COX2 (an NSAID target/pro-oncogenic inflammation) and splicing regulators, and (d) lower tumor suppressor activities (e.g., TOB2, PCGF2, BAP1). Therefore, targeting strategies designed for white CRC patients may be less effective for AAs/AIs. These findings illustrate needs to develop optimized interventions to overcome racial CRC disparities.

A Systematic Review of Patient Race, Ethnicity, Socioeconomic Status, and Educational Attainment in Prostate Cancer Treatment Randomised Trials-Is the Evidence Base Applicable to the General Patient Population?

Context

Prostate cancer (PC) disproportionately affects men of Black race, and lower educational and socioeconomic status. Guidelines are based on randomised controlled trials (RCTs); however, the representation of different races, educations, and socioeconomic backgrounds in these trials is unclear.

Objective

To assess reporting of equality, diversity, and inclusion characteristics (Equality, Diversity and Inclusion [EDI]) and differences in treatment effects between different races, and educational or socioeconomic status.

Evidence acquisition

We conducted a systematic review of CENTRAL, MEDLINE, and Embase in April 2020 examining RCTs investigating treatments for PC. Outcomes collected were race/ethnicity, educational attainment, and socioeconomic status. RCTs investigating PC treatment in any population or setting were included. Data extraction of characteristics was performed independently by pairs of reviewers and checked by a senior author. The Cochrane risk of bias tool assessed the quality of included papers.

Evidence synthesis

A total of 265 trials were included, and 138 of these were available as full-text articles. Fifty-four trials including 19 039 participants reported any EDI data. All 54 trials reported race, 11 reported ethnicity, three reported educational attainment, and one reported socioeconomic status. Patients of White race were the majority of the recruited population (82.6%), while the minority prevalence was as follows: Black 9.8% and Asian 5.7%. Three studies reported mortality outcomes depending on the participant's race. All three studies investigated different treatments, so a meta-analysis was not performed. No studies reported outcomes stratified by the educational or socioeconomic status of participants.

Conclusions

There is poor reporting of patient race, ethnicity, socioeconomic background, and educational attainment in RCTs for PC treatments between 2010 and 2020. Addressing this for future studies will help explain differences in the incidence of and mortality from PC and improve the generalisability of results.

Patient summary

In this study, we reviewed prostate cancer treatment trials to see whether these reported race, education, and socioeconomic backgrounds of their patient populations. We conclude that reporting of these characteristics is poor. This needs to be improved in future to improve outcomes for patients with prostate cancer of all ethnical, racial, and socioeconomic groups.

A Survey of Cancer Risk Behaviors, Beliefs, and Social Drivers of Health in New Hampshire and Vermont

Compared with urban areas, rural areas have higher cancer mortality and have experienced substantially smaller declines in cancer incidence in recent years. In a New Hampshire (NH) and Vermont (VT) survey, we explored the roles of rurality and educational attainment on cancer risk behaviors, beliefs, and other social drivers of health. In February-March 2022, two survey panels in NH and VT were sent an online questionnaire. Responses were analyzed by rurality and educational attainment. Respondents (N = 1,717, 22%) mostly lived in rural areas (55%); 45% of rural and 25% of urban residents had high school education or less and this difference was statistically significant. After adjustment for rurality, lower educational attainment was associated with smoking, difficulty paying for basic necessities, greater financial difficulty during the COVID-19 pandemic, struggling to pay for gas (P < 0.01), fatalistic attitudes toward cancer prevention, and susceptibility to information overload about cancer prevention. Among the 33% of respondents who delayed getting medical care in the past year, this was more often due to lack of transportation in those with lower educational attainment (21% vs. 3%, P = 0.02 adjusted for rurality) and more often due to concerns about catching COVID-19 among urban than rural residents (52% vs. 21%; P < 0.001 adjusted for education). In conclusion, in NH/VT, smoking, financial hardship, and beliefs about cancer prevention are independently associated with lower educational attainment but not rural residence. These findings have implications for the design of interventions to address cancer risk in rural areas.

Significance

In NH and VT, the finding that some associations between cancer risk factors and rural residence are more closely tied to educational attainment than rurality suggest that the design of interventions to address cancer risk should take educational attainment into account.

Lung and Colorectal Cancer Disparities in Appalachian Kentucky: Spatial Analysis on the Influence of Education and Literacy

Low educational attainment and high cancer incidence and mortality rates have long been a challenge in Appalachian Kentucky. Prior studies have reported disparities in cancer incidence and mortality between Appalachian and non-Appalachian populations, but the influence of education on this disparity has not been extensively studied. Herein, all cancers and two cancer sites with available screenings (colorectal and lung) were joined with education indicators (educational attainment and literacy) and one geographic indicator across all 120 Kentucky counties. This dataset was used to build choropleth maps and perform simple linear and spatial regression to assess statistical significance and to measure the strength of the linear relationship between county-level education and cancer-related outcomes in Appalachian and non-Appalachian Kentucky. Among all cancer sites, age-adjusted cancer incidence and mortality was higher in Appalachian versus non-Appalachian Kentucky. The percentage of the population not completing high school was positively correlated with increased colorectal and lung cancer incidence and mortality in Appalachia. Similarly, counties with a higher percentage of the population lacking basic literacy had the strongest correlation with colorectal and lung cancer incidence and mortality, which were concentrated in Appalachian Kentucky. Our findings suggest a need for implementing interventions that increase educational attainment and enhance basic literacy as a means of improving cancer outcomes in Appalachia.

Inequity in care delivery in cardio-oncology: dissecting disparities in underrepresented populations

It is well known that patients with cancer have a significantly higher cardiovascular mortality risk than the general population. Cardio-oncology has emerged to focus on these issues including risk reduction, detection, monitoring, and treatment of cardiovascular disease or complications in patients with cancer. The rapid advances in early detection and drug development in oncology, along with socioeconomic differences, racial inequities, lack of support, and barriers to accessing quality medical care, have created disparities in various marginalized populations. In this review, we will discuss the factors contributing to disparities in cardio-oncologic care in distinct populations, including Hispanic/Latinx, Black, Asian and Pacific Islander, indigenous populations, sex and gender minorities, and immigrants. Some factors that contribute to differences in outcomes in cardio-oncology include the prevalence of cancer screening rates, genetic cardiac/oncologic risk factors, cultural stressors, tobacco exposure rates, and physical inactivity. We will also discuss the barriers to cardio-oncologic care in these communities from the racial and socioeconomic context. Appropriate and timely cardiovascular and cancer care in minority groups is a critical component in addressing these disparities, and there need to be urgent efforts to address this widening gap.

Disparities in lung cancer

Lung cancer is the second most common cancer and the leading cause of cancer death among men and women in the United States. Despite a substantial decline in lung cancer incidence and mortality across all races in the last few decades, medically underserved racial and ethnic minority populations continue to carry the greatest burden of disease throughout the lung cancer continuum. Black individuals experience a higher incidence of lung cancer due to lower rates of low-dose computed tomography screening, which translate into advanced disease stage at diagnosis and poorer survival outcomes compared with White individuals. With respect to treatment, Black patients are less likely to receive gold standard surgery, have access to biomarker testing or high-quality treatment compared with White patients. The reasons for those disparities are multifactorial and include socioeconomic (eg, poverty, lack of health insurance, and inadequate education), and geographic inequalities. The objective of this article is to review the sources of racial and ethnic disparities in lung cancer, and to propose recommendations to help address them.

The impacts of the scope of benefits expansion on hospice care among adult decedents: a nationwide longitudinal observational study

OBJECTIVES

Compared to aggressive treatment for patients at the end stage of life, hospice care might be more likely to satisfy such patients' need and benefits and improve their dignity and quality of life. Whether the reimbursement policy expansion affect the use of hospice care among various demographics characteristics and health status was unknown. Therefore, the purpose of this study was to explore the impacts of reimbursement policy expansion on hospice care use, and to investigate the effects on people with various demographics characteristics and health status.

METHODS

We used the 2001-2017 Taiwan NHI claims data, Death Registry, and Cancer Registry in this study, and we included people who died between 2002 and 2017. The study period was divided into 4 sub-periods. hospice care use and the initiation time of 1st hospice care use were used as dependent variables; demographic characteristics and health status were also collected.

RESULTS

There were 2,445,781 people who died in Taiwan during the study period. The results show that the trend of hospice care use increased over time, going steeply upward after the scope of benefits expansion, but the initiation time of 1st hospice care use did not increase after the scope of benefits expansion. The results also show that the effects of expansion varied among patients by demographic characteristics.

CONCLUSION

The scope of benefits expansion might induce people's needs in hospice care, but the effects varied by demographic characteristics. Understanding the reasons for the variations in all populations would be the next step for Taiwan's health authorities.

The Colocation Model in Community Cancer Care: A Description of Patient Clinical and Demographic Attributes and Referral Pathways

PURPOSE

Cancer disparities are well documented among Black, Indigenous, and People of Color, yet little is known about the characteristics of programs that serve these populations. Integrating specialized cancer care services within community settings is important for addressing the needs of historically marginalized populations. Our National Cancer Institute-Designated Cancer Center initiated a clinical outreach program incorporating cancer diagnostic services and patient navigation within a Federally Qualified Health Center (FQHC) to expedite evaluation and resolution of potential cancer diagnoses with the goal of collaboration between oncology specialists and primary care providers in a historically marginalized community in Boston, MA.

MATERIALS AND METHODS

Sociodemographic and clinical characteristics were analyzed from patients who were referred to the program for cancer-related care between January 2012 and July 2018.

RESULTS

The majority of patients self-identified as Black (non-Hispanic) followed by Hispanic (Black and White). Twenty-two percent of patients had a cancer diagnosis. Treatment and surveillance plans were established for those with and without cancer at a median time to diagnostic resolution of 12 and 28 days, respectively. The majority of patients presented with comorbid health conditions. There was a high prevalence of self-reported financial distress among patients seeking care through this program.

CONCLUSION

These findings highlight the wide spectrum of cancer care concerns in historically marginalized communities. This review of the program suggests that integrating cancer evaluation services within community-based primary health care settings offers promise for enhancing the coordination and delivery of cancer diagnostic services among historically marginalized populations and could be a method to address clinical access disparities.

Impact of the COVID-19 pandemic on breast, colorectal, lung, and prostate cancer stage at diagnosis according to race

PURPOSE

To determine if the COVID-19 pandemic has further exacerbated racial disparities in late-stage presentation of breast, colorectal, lung, and prostate cancers.

METHODS

We conducted a registry-based retrospective study of patients with newly reported diagnoses of breast, colorectal, lung, and prostate cancers between March 2019-June 2019 (pre-COVID-19) and March 2020-June 2020 (early-COVID-19). We compared the volume of new diagnoses and stage at presentation according to race between both periods.

RESULTS

During the study period, a total of 3528 patients had newly diagnosed cancer; 3304 of which had known disease stages and were included in the formal analyses. 467 (14.1%) were Blacks, and 2743 were (83%) Whites. 1216 (36.8%) had breast, 415 (12.6%) had colorectal, 827 (25%) had lung, and 846 (25.6%) had prostate cancers, respectively. The pre-COVID-19 period included 2120 (64.2%), and the early-COVID-19 period included 1184 (35.8%), representing a proportional 44.2% decline in the volume of new cases of breast, colorectal, lung, and prostate cancers, p < 0.0001. Pre-COVID-19, 16.8% were diagnosed with metastatic disease, versus 20.4% early-COVID-19, representing a proportional increase of 21.4% in the numbers of new cases with metastatic disease, p = 0.01. There was a non-significant proportional decline of 1.9% in Black patients diagnosed with non-metastatic breast, colorectal, lung, and prostate cancers early-COVID-19 (p = 0.71) and a non-significant proportional increase of 7% in Black patients diagnosed with metastatic disease (p = 0.71). Difference-in-difference analyses showed no statistically significant differences in metastatic presentation comparing Black to White patients.

CONCLUSION

While we identified substantial reductions in the volume of new cancer diagnoses and increases in metastatic presentations due to the COVID-19 pandemic, the impact was similar for White and Black patients.

Oncology distress screening within predominately Black Veterans: Outcomes on supportive care utilization, hospitalizations, and mortality

BACKGROUND

We evaluated whether patients' initial screening symptoms were related to subsequent utilization of supportive care services and hospitalizations, and whether patient-level demographics, symptoms, hospitalizations, and supportive care service utilization were associated with mortality in primarily low-income, older, Black Veterans with cancer.

METHODS

This quality improvement project created collaborative clinics to conduct cancer distress screenings and refer to supportive care services at an urban, VA medical center. All patients completed a distress screen with follow-up screening every 3 months. Supportive care utilization, hospitalization rates, and mortality were abstracted through medical records. Poisson regression models and cox proportional hazard models were utilized.

RESULTS

Five hundred and eighty five screened patients were older (m = 72), mostly Black 70% (n = 412), and had advanced cancer 54%. Fifty-eight percent (n = 340) were screened only once with 81% (n = 470) receiving ≥1 supportive care service and 51.5% (n = 297) being hospitalized ≥1 time 18 months following initial screen. Symptom severity was significantly related to number of hospitalizations. Low mood was significantly related to higher supportive services (p < 0.001), but not hospitalizations (p ≥ 0.52). Pain, fatigue, physical function, nutrition, and physical symptoms were significantly associated with more supportive services and hospitalizations (p < 0.01). Twenty percent (n = 168) died; Veterans who were Black, had lower stage cancers, better physical health, and utilized less supportive care services had lower odds of mortality (p ≤ 0.01).

CONCLUSION

Individuals with elevated distress needs and those reporting lower physical function utilized more supportive care services and had higher hospitalization rates. Lower physical function, greater supportive care use, higher stage cancer, and being non-Black were associated with higher odds of death.

Sexual Dysfunction among Gynaecological Cancer Survivors: A Descriptive Cross-Sectional Study in Malaysia

BACKGROUND

Sexual dysfunction is a major issue among gynaecological cancer survivors. This study aimed to evaluate the prevalence of sexual dysfunction among survivors of gynaecological cancer in Malaysia and to determine its risk factors.

METHODS

A cross-sectional study was conducted of 116 married women with gynaecological cancer who attended the gynaeoncology and oncology clinics at Universiti Kebangsaan Malaysia Medical Centre (UKMMC). Sociodemographic and clinical data were collected. Sexual dysfunction was measured using the Malay Version Female Sexual Function Index (MVFSFI). Univariate and multivariate logistic regression analyses were used to determine the risk factors of female sexual dysfunction.

RESULTS

The prevalence of sexual dysfunction among gynaecological cancer survivors was 60% (70 out of 116). Sexual dissatisfaction was the most prevalent domain of sexual dysfunction at 68.1%. Sexual dysfunction was significantly associated with low education levels (Primary level, AOR = 4.92, 95% CI: 1.12-21.63; secondary level, AOR = 4.06, 95% CI: 1.14-14.44). Non-Malays were significantly more likely to have sexual dysfunction compared with Malays (AOR = 3.57, 95% CI: 1.16-11.06). In terms of treatment, combinations of surgery and radiotherapy (AOR = 4.66, 95% CI: 1.01-21.47) as well as surgery and chemoradiation (AOR = 5.77, 95% CI: 1.20-27.85) were considered.

CONCLUSIONS

Gynaecological cancer survivors with lower education levels, non-Malay ethnicity, and receiving treatment combinations of surgery and radiotherapy or surgery and chemoradiation have a higher risk of sexual dysfunction. A holistic approach in managing the various sociocultural and clinical issues is required to prevent sexual dysfunction among these patients.

Spatial Analysis of Breast Cancer Mortality Rates in a Rural State

Introduction

Breast cancer affects 1 in 8 women in the US and is the most frequently diagnosed cancer in women. In South Dakota, 102 women die from breast cancer each year. We assessed which sociodemographic factors contributed to mortality rates in South Dakota and used spatial analysis to investigate how counties’ observed age-adjusted mortality rates compared with expected rates.

Methods

We computed standardized incidence ratios (SIRs) of all counties in South Dakota by using the age-adjusted mortality rates, the 2000 US standard population, and the South Dakota estimated population. We used a linear regression model to identify sociodemographic factors associated with breast cancer mortality rates and to compute a new SIR value, after controlling for relevant factors.

Results

Educational level and breast cancer incidence rates were significantly associated with breast cancer mortality rates at the county level. The SIR values based on age-adjusted counts showed which counties had more deaths due to breast cancer than what might be expected using South Dakota as the reference population. After controlling for sociodemographic factors, the range of SIR values decreased and had lower variability.

Conclusion

The regression model helped identify factors associated with mortality and provided insights into which risk factors are at play in South Dakota. This information, in combination with the spatial distribution of mortality by county, can be used to help allocate resources to the counties in South Dakota that need them most.

Rectal Cancer and Diabetes Relationship: An Evidence-Based Overview for Healthcare Providers

As the third most frequently diagnosed cancer through the worldwide, colorectal cancer (CRC) is the fourth leading cause and account for around 8% of all cancer-related death. Diabetes mellitus (DM) is a complex metabolic disorder characterized by chronic hyperglycemia and inflammation due to deficiency in insulin secretion or dysregulation of the insulin action pathway, which further leads to dysfunction and failure of multiple organs. Many advances have been made in the diagnosis and management of rectal cancer. Although colorectal cancer survival is severely dependent on the stage of disease at diagnosis, it might also be influenced by several risk factors. The relationship between colorectal cancer and diabetes is a complex one and can raise problems in both diagnosis and the management of patients with both conditions. Metabolic pathways of the type II diabetes, glucose intolerance and obesity can be considered as a link to rectal cancer. This article provides not just an overview of the epidemiology, diagnosis and management of CRC and DM, but also highlights of CRC and DM relationship.

Progress in Reducing Disparities in Premature Mortality in the USA: a Descriptive Study

BACKGROUND

Eliminating health disparities among different segments of the US population is an overarching goal of the US Healthy People 2020 objectives.

OBJECTIVE

Examine changes in educational, rural-urban, and racial disparities in premature mortality during the past 10 years.

DESIGN AND PARTICIPANTS

Descriptive analysis of US mortality data from 2007 to 2017.

MAIN MEASURES

Relative and absolute rural-urban, educational attainment, and Black-White disparities in premature mortality for all-cause and top 10 causes of death among persons ages 25-74 years, estimated as rate ratios and rate differences between ≤12 and ≥16 years of education, rural versus urban, and non-Hispanic Black (Black) versus non-Hispanic White (White), respectively, in 2007 and 2017.

KEY RESULTS

During 2007-2017, mortality rates in persons aged 25-74 years in the USA increased for several leading causes of death, especially in persons with <16 years of education, rural residents, and White people. As a result, disparity in mortality between 2007 and 2017 widened on both relative and absolute scales for all-cause and for 6 of the top 10 causes of death by education and for all-cause and for 9 of the top 10 causes by rural/urban residence. In contrast, Black-White disparities narrowed for all-cause and for all 7 causes that Black people had a higher rate than White people. For all-cause mortality for example, absolute disparities in the number of deaths per 100,000 person-years between 2007 and 2017 increased from 454.0 (95%CI, 446.0-462.1) to 542.7 (535.6-549.7) for educational attainment and from 85.8 (82.8-88.8) to 140.5 (137.6-143.4) for rural versus urban; in contrast, absolute Black-White disparity decreased from 315.3 (311.0-319.7) to 221.7 (218.1-225.3).

CONCLUSIONS

Educational and rural-urban disparities in premature mortality widened, whereas Black-White disparities narrowed in the USA between 2007 and 2017, though overall rates remained considerably higher in Black people.

Role of Occupation in Shaping Cancer Disparities

Simple Summary

The investigation of cancer disparities is of major importance. In this paper, we address this issue through the occupational point of view, trying to capture how work and its related factors impact on cancer inequalities. The data we provide may increase awareness relevant to cancer control, and stimulate further studies aimed at the identification of the occupational determinants of cancer disparities and the quantification of their role.

Abstract

Cancer occurrence is characterized globally by profound socioeconomic differences. Occupation is a fundamental component of socioeconomic status. In this review, we discuss the role of occupation as a determinant of cancer disparities. First, we address the issue of participation in cancer screening programs based on income, health insurance, occupational status and job title. Second, we review the role of occupation in contributing to disparities by acting as a mediator between cancer and (i) education and (ii) race/ethnicity. Lastly, we analyze data from a multicenter case−control study of lung cancer to calculate the mediating role of occupational exposure to diesel exhaust, silica and welding fumes in the association between education and lung cancer. By addressing the complex paths from occupation to cancer inequalities from multiple points of view, we provide evidence that occupational-related characteristics, such as income, health insurance, unemployment and hazardous exposures impinge on cancer control and outcomes. The increasing awareness of these aspects is fundamental and should lead to public health interventions to avoid inequalities rising from occupational factors.

A nationwide analysis of clinical trial participation for common hepato-pancreato-biliary malignancies demonstrates survival advantages for subsets of trial patients but disparities in and infrequency of enrollment

BACKGROUND

We describe factors associated with trial enrollment for patients with hepato-pancreato-biliary (HPB) malignancies. We analyzed the association and effect of trial enrollment on overall survival (OS).

METHODS

The National Cancer Database (2004-2017) was queried for common HPB malignancies (pancreatic adenocarcinoma [PDAC] & neuroendocrine tumors, hepatocellular carcinoma [HCC], biliary tract cancers [BTC]). Multivariable logistic regression was used to identify factors associated with trial enrollment. OS was analyzed by multivariable Cox regression. Inverse-probability-weighted Cox regression was utilized to determine the effect of trial enrollment on OS.

RESULTS

A total of 1573 (0.3%) of 511,639 patients were enrolled in trials; pancreatic malignancy: 1214 (0.4%); HCC: 217 (0.14%); BTC: 106 (0.15%). HCC and BTC were associated with lower likelihood of enrollment compared with pancreatic malignancy. Black and Hispanic patients were less likely to be enrolled compared to White patients. Treatment at academic facilities and metastatic disease were associated with higher likelihood of enrollment. Enrollment was associated with higher OS for PDAC, metastatic HCC, and metastatic BTC. Trial enrollment exhibited an OS advantage for PDAC and metastatic HCC.

CONCLUSION

Nationally, fewer than 1% of patients with HPB malignancies were enrolled in clinical trials. There are racial, sociodemographic, and facility-based disparities in trial enrollment.

Influence of geographic access and socioeconomic characteristics on breast cancer outcomes: A systematic review

Socio-economic and geographical inequalities in breast cancer mortality have been widely described in European countries and the United States. To investigate the combined effects of geographic access and socio-economic characteristics on breast cancer outcomes, a systematic review was conducted exploring the relationships between: (i) geographic access to healthcare facilities (oncology services, mammography screening), defined as travel time and/or travel distance; (ii) breast cancer-related outcomes (mammography screening, stage of cancer at diagnosis, type of treatment and rate of mortality); (iii) socioeconomic status (SES) at individuals and residential context levels. In total, n = 25 studies (29 relationships tested) were included in our systematic review. The four main results are: The statistical significance of the relationship between geographic access and breast cancer-related outcomes is heterogeneous: 15 were identified as significant and 14 as non-significant. Women with better geographic access to healthcare facilities had a statistically significant fewer mastectomy (n = 4/6) than women with poorer geographic access. The relationship with the stage of the cancer is more balanced (n = 8/17) and the relationship with cancer screening rate is not observed (n = 1/4). The type of measures of geographic access (distance, time or geographical capacity) does not seem to have any influence on the results. For example, studies which compared two different measures (travel distance and travel time) of geographic access obtained similar results. The relationship between SES characteristics and breast cancer-related outcomes is significant for several variables: at individual level, age and health insurance status; at contextual level, poverty rate and deprivation index. Of the 25 papers included in the review, the large majority (n = 24) tested the independent effect of geographic access. Only one study explored the combined effect of geographic access to breast cancer facilities and SES characteristics by developing stratified models.

Racial/Ethnic Disparities in Mortality Related to Access to Care for Major Cancers in the United States

Importance: The reasons underlying racial/ethnic mortality disparities for cancer patients remain poorly understood, especially regarding the role of access to care. Participants: Over five million patients with a primary diagnosis of lung, breast, prostate, colon/rectum, pancreas, ovary, or liver cancer during 2004-2014, were identified from the National Cancer Database. Cox proportional hazards models were applied to estimate hazard ratios (HR) and 95% confidence intervals (CI) for total mortality associated with race/ethnicity, and access to care related factors (i.e., socioeconomic status [SES], insurance, treating facility, and residential type) for each cancer. Results: Racial/ethnic disparities in total mortality were observed across seven cancers. Compared with non-Hispanic (NH)-white patients, NH-black patients with breast (HR = 1.27, 95% CI: 1.26 to 1.29), ovarian (HR = 1.20, 95% CI: 1.17 to 1.23), prostate (HR = 1.31, 95% CI: 1.30 to 1.33), colorectal (HR = 1.11, 95% CI: 1.10 to 1.12) or pancreatic (HR = 1.03, 95% CI: 1.02 to 1.05) cancers had significantly elevated mortality, while Asians (13-31%) and Hispanics (13-19%) had lower mortality for all cancers. Racial/ethnic disparities were observed across all strata of access to care related factors and modified by those factors. NH-black and NH-white disparities were most evident among patients with high SES or those with private insurance, while Hispanic/Asian versus NH-white disparities were more evident among patients with low SES or those with no/poor insurance. Conclusions and Relevance: Racial/ethnic mortality disparities for major cancers exist across all patient groups with different access to care levels. The influence of SES or insurance on mortality disparity follows different patterns for racial/ethnic minorities versus NH-whites. Impact: Our study highlights the need for racial/ethnic-specific strategies to reduce the mortality disparities for major cancers.

Re-examining phone counseling for smoking cessation: Does the evidence apply to low-SES smokers?

INTRODUCTION

A 2019 Cochrane review concluded telephone counseling is an effective intervention for smoking cessation. However, the review did not assess the role of socioeconomic status (SES) indicators on the effectiveness of telephone counseling.

METHODS

We reviewed 65 U.S. studies from the Cochrane review. We abstracted data on education, income, employment status and insurance status, and examined associations with targeted recruitment, intervention uptake, attrition, and cessation outcomes.

RESULTS

Except for education, SES indicators were seldom reported or used in analysis: 61 studies reported education, 24 reported insurance status, 23 reported employment status, and 17 reported income. Nine studies exclusively recruited low-SES samples. Thirteen studies examined associations between SES and smoking cessation. Among these, two reported lower education predicted greater cessation and two reported higher education predicted greater cessation. Other studies found higher income (n = 2) or employment type (n = 1) predicted cessation.

CONCLUSIONS

Evidence supporting telephone counseling for cessation is less clear when applied to low-SES smokers. Future research should directly assess intervention effectiveness in this priority population.

PRACTICE IMPLICATIONS

Given the evidence, it may be hard to justify future studies not focusing on low-SES populations. Innovative counseling solutions from providers helping low-income smokers quit should be evaluated to inform best practice.

Elevated breast cancer mortality among highly educated Asian American women

Background

Postmenopausal breast cancer (PMBC) is the most commonly diagnosed and the second leading cause of cancer death among women in the US. Research examining the association between PMBC and education level has been inconsistent; no study in the US has examined how educational level impacts PMBC mortality in Asian American women, a largely immigrant population with above-average educational attainment.

Methods

California Vital Statistics data from 2012–2017 were analyzed to derive age-adjusted mortality rate ratios (MRRs) by education level (associates degree or above referred to as “higher education”, high school, less than high school) and race [Non-Hispanic White (NHW), Asian/Pacific Islander (Asian), and its two largest subpopulations: Chinese and Filipino] from negative binomial regression models.

Results

PMBC mortality for both NHWs and Asians was greater among women with higher education compared to those who did not complete high school: NHWs had 22% higher PMBC mortality (MRR 1.22; 95% CI: 1.14–1.31) and Asians had 2.6 times greater PMBC mortality (MRR 2.64; 95% CI: 2.32–3.00) than their counterparts who did not complete high school. Asians in the lowest education level had 70% lower mortality than NHWs (MRR 0.30; 95% CI: 0.27–0.34). This mortality advantage among Asians was greatly reduced to only 27% lower among the highest educated (MRR 0.73; 95% CI: 0.68–0.78). For higher educated Filipina women, no mortality advantage was evident compared to NHWs (MRR 0.96; 95% CI: 0.88–1.05).

Conclusion

PMBC mortality for higher educated Asian women is elevated in comparison to their counterparts with less education. Given that PMBC survival is greater among those with higher education, our findings strongly suggest an excess in the incidence of PMBC (more than double) among higher educated Asian women; this warrants more research into potentially modifiable causes of PMBC in this burgeoning population.

Survival of Adolescents and Young Adults with Prevalent Poor-Prognosis Metastatic Cancers: A Population-Based Study of Contemporary Patterns and Their Implications

BACKGROUND

Although survival has improved dramatically for most adolescents and young adults (AYA; 15-39 years old) with cancer, it remains poor for those presenting with metastatic disease. To better characterize this subset, we conducted a landscape survival comparison with older adults (40-79 years).

METHODS

Using Surveillance, Epidemiology, and End Results Program data from 2000 to 2016, we examined incident cases of poor-prognosis metastatic cancers (5-year survival < 50%) among AYAs (n = 11,518) and older adults (n = 345,681) and compared cause-specific survival by sociodemographic characteristics (race/ethnicity, sex, and socioeconomic status). Adjusted HRs (aHR) for death from metastatic disease [95% confidence intervals (95% CI)] were compared between AYAs and older adults (Pint).

RESULTS

AYAs had significantly better survival than older adults for every cancer site except kidney, where it was equivalent (range of aHRs = 0.91; 95% CI, 0.82-1.02 for kidney cancer to aHR = 0.33; 95% CI, 0.26-0.42 for rhabdomyosarcoma). Compared with their older adult counterparts, greater survival disparities existed for AYAs who were non-Hispanic Black with uterine cancer (aHR = 2.20; 95% CI, 1.25-3.86 versus aHR = 1.40; 95% CI, 1.28-1.54; Pint = 0.049) and kidney cancer (aHR = 1.51; 95% CI, 1.15-1.98 versus aHR = 1.10; 95% CI, 1.03-1.17; Pint = 0.04); non-Hispanic Asian/Pacific Islanders with ovarian cancer (aHR = 1.47; 95% CI, 1.12-1.93 versus aHR = 0.89; 95% CI, 0.84-0.95; Pint<0.001); and males with colorectal cancer (aHR = 1.21; 95% CI, 1.10-1.32 versus aHR = 1.08; 95% CI, 1.06-1.10; Pint = 0.045).

CONCLUSIONS

AYAs diagnosed with these metastatic cancers have better survival than older adults, but outcomes remain dismal.

IMPACT

Overcoming the impact of metastasis in these cancers is necessary for continuing progress in AYA oncology. Sociodemographic disparities affecting AYAs within kidney, uterine, ovarian, and colorectal cancer could indicate plausible effects of biology, environment, and/or access and should be explored.

The Role of Safety-Net Hospitals in Reducing Disparities in Breast Cancer Care

Advances in breast cancer screening and systemic therapies have been credited with profound improvements in breast cancer outcomes; indeed, 5-year relative survival rate approaches 91% in the USA (U.S. National Institutes of Health NCI. SEER Training Modules, Breast). While breast cancer mortality has been declining, oncologic outcomes have not improved equally among all races and ethnicities. Many factors have been implicated in breast cancer disparities; chief among them is limited access to care which contributes to lower rates of timely screening mammography and, once diagnosed with breast cancer, lower rates of receipt of guideline concordant care (Wu, Lund, Kimmick GG et al. in J Clin Oncol 30(2):142-150, 2012). Hospitals with a safety-net mission, such as the essential hospitals, historically have been dedicated to providing high-quality care to all populations and have eagerly embraced the role of caring for the most vulnerable and working to eliminate health disparities. In this article, we review landmark articles that have evaluated the role safety-net hospitals have played in providing equitable breast cancer care including to those patients who face significant social and economic challenges.

Cancer-Specific Mortality in Asian American Women Diagnosed with Gynecologic Cancer: A Nationwide Population-Based Analysis

BACKGROUND

Cancer is the leading cause of death in Asian Americans (AA), the fastest-growing U.S. population group. Despite heterogeneity in socioeconomic status and health behaviors by ethnicity, few studies have assessed cancer outcomes across AA ethnic groups. We examined differences in gynecologic cancer mortality between AA ethnic groups and non-Hispanic Whites (NHW).

METHODS

Using the Surveillance, Epidemiology, and End Results database, we identified ovarian (n = 69,113), uterine (n = 157,340), and cervical cancer cases (n = 41,460) diagnosed from 1991-2016. Competing risk regression was used to compare cancer-specific mortality for AAs by ethnicity, using NHW as the reference population.

RESULTS

In adjusted analyses, AAs had a lower risk of ovarian [HR, 0.90; 95% confidence interval (CI), 0.86-0.94] and cervical cancer death (HR, 0.80; 95% CI, 0.75-0.87) than NHWs, with stronger associations among those ≥50 years at diagnosis [(HRovary, 0.87; 95% CI, 0.82-0.92); (HRcervix, 0.74; 95% CI, 0.67-0.81)]. No overall difference was noted for uterine cancer death (HR, 1.03; 95% CI, 0.97-1.10); however, AAs <50 years at diagnosis had a higher risk of uterine cancer death than NHWs (HR, 1.26; 95% CI, 1.08-1.46). Patterns of cancer mortality were heterogeneous, with Filipino and Chinese women at the highest risk of uterine cancer death and Indian/Pakistani women at the lowest risk of ovarian and cervical cancer death.

CONCLUSIONS

There are significant differences in gynecologic cancer mortality between AAs and NHWs, with heterogeneity by AA ethnicity.

IMPACT

Disaggregated analysis of AA is needed to better understand the burden of gynecologic cancer and identify high-risk groups for cancer prevention efforts.

The Kaiser Permanente Research Bank Cancer Cohort: a collaborative resource to improve cancer care and survivorship

Background

The Kaiser Permanente Research Bank (KPRB) is collecting biospecimens and surveys linked to electronic health records (EHR) from approximately 400,000 adult KP members. Within the KPRB, we developed a Cancer Cohort to address issues related to cancer survival, and to understand how genetic, lifestyle and environmental factors impact cancer treatment, treatment sequelae, and prognosis. We describe the Cancer Cohort design and implementation, describe cohort characteristics after 5 years of enrollment, and discuss future directions.

Methods

Cancer cases are identified using rapid case ascertainment algorithms, linkage to regional or central tumor registries, and direct outreach to KP members with a history of cancer. Enrollment is primarily through email invitation. Participants complete a consent form, survey, and donate a blood or saliva sample. All cancer types are included.

Results

As of December 31, 2020, the cohort included 65,225 cases (56% female, 44% male) verified in tumor registries. The largest group was diagnosed between 60 and 69 years of age (31%) and are non-Hispanic White (83%); however, 10,076 (16%) were diagnosed at ages 18–49 years, 4208 (7%) are Hispanic, 3393 (5%) are Asian, and 2389 (4%) are Black. The median survival time is 14 years. Biospecimens are available on 98% of the cohort.

Conclusions

The KPRB Cancer Cohort is designed to improve our understanding of treatment efficacy and factors that contribute to long-term cancer survival. The cohort’s diversity - with respect to age, race/ethnicity and geographic location - will facilitate research on factors that contribute to cancer survival disparities.

EDUCATION AND INCOME GRADIENTS IN LONGEVITY: THE ROLE OF POLICY

Education and income are strong predictors of health and longevity. In the last 20 years many efforts have been made to understand if these relationships are causal and what the possible role of policy should be as a result. The evidence from various studies is ambiguous: the effects of education and income policies on health are heterogeneous and vary over time, and across places and populations. I discuss explanations for these disparate results and suggest directions for future research.

Explainable artificial intelligence (XAI) for exploring spatial variability of lung and bronchus cancer (LBC) mortality rates in the contiguous USA

Machine learning (ML) has demonstrated promise in predicting mortality; however, understanding spatial variation in risk factor contributions to mortality rate requires explainability. We applied explainable artificial intelligence (XAI) on a stack-ensemble machine learning model framework to explore and visualize the spatial distribution of the contributions of known risk factors to lung and bronchus cancer (LBC) mortality rates in the conterminous United States. We used five base-learners-generalized linear model (GLM), random forest (RF), Gradient boosting machine (GBM), extreme Gradient boosting machine (XGBoost), and Deep Neural Network (DNN) for developing stack-ensemble models. Then we applied several model-agnostic approaches to interpret and visualize the stack ensemble model's output in global and local scales (at the county level). The stack ensemble generally performs better than all the base learners and three spatial regression models. A permutation-based feature importance technique ranked smoking prevalence as the most important predictor, followed by poverty and elevation. However, the impact of these risk factors on LBC mortality rates varies spatially. This is the first study to use ensemble machine learning with explainable algorithms to explore and visualize the spatial heterogeneity of the relationships between LBC mortality and risk factors in the contiguous USA.
