Abstract
INTRODUCTION Breast cancer treatment patterns and quality of care among patients experiencing incarceration are underexplored. This study examined associations between incarceration and breast cancer disease and treatment characteristics. METHODS This retrospective analysis was conducted at a tertiary center in the Southeastern United States that serves as the state's safety-net hospital and primary referral site for the state's prisons. All patients ≥18 years diagnosed with breast cancer between 4/14/2014-12/30/2020 were included. Incarceration status was determined through electronic health record review. Linear regression was used to estimate the association of incarceration with time to treatment. Unadjusted overall survival (OS) was estimated using the Kaplan-Meier method with log-rank tests to compare groups. RESULTS Of the 4329 patients included, 30 (0.7%) were incarcerated at the time of diagnosis or treatment (DI) and 4299 (99.3%) had no incarceration history (NI). Compared to patients who were NI, patients who were DI were younger (p < 0.001), more likely to be unmarried (p < 0.001), and more likely to have family history of breast cancer (p = 0.02). Patients who were DI had an increased time from diagnosis to neoadjuvant chemotherapy (+47.2 days on average, 95% CI 3.9-90.5, p = 0.03) and from diagnosis to surgery (+20 days on average, 95% CI 6.5-33.5, p = 0.02) compared to NI patients. No difference in OS was observed (log-rank p = 0.70). CONCLUSIONS Patients who are incarcerated experienced significant delays in breast cancer care. While no differences in mortality were appreciated, these findings are concerning, as they indicate poorer care coordination for patients who are incarcerated. Further research is necessary to understand the full scope of these disparities and elucidate factors that contribute to them.

Understanding mechanisms of racial disparities in breast cancer: an assessment of screening and regular care in the Carolina Breast Cancer Study. Cancer Causes Control 2024; 35:825-837. [PMID: 38217760 PMCID: PMC11045315 DOI: 10.1007/s10552-023-01833-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/28/2023] [Accepted: 11/16/2023] [Indexed: 01/15/2024]
Abstract
PURPOSE Screening history influences stage at detection, but regular preventive care may also influence breast tumor diagnostic characteristics. Few studies have evaluated healthcare utilization (both screening and primary care) in racially diverse screening-eligible populations. METHODS This analysis included 2,058 women age 45-74 (49% Black) from the Carolina Breast Cancer Study, a population-based cohort of women diagnosed with invasive breast cancer between 2008 and 2013. Screening history (threshold 0.5 mammograms per year) and pre-diagnostic healthcare utilization (i.e. regular care, based on responses to "During the past ten years, who did you usually see when you were sick or needed advice about your health?") were assessed as binary exposures. The relationship between healthcare utilization and tumor characteristics were evaluated overall and race-stratified. RESULTS Among those lacking screening, Black participants had larger tumors (5 + cm) (frequency 19.6% vs 11.5%, relative frequency difference (RFD) = 8.1%, 95% CI 2.8-13.5), but race differences were attenuated among screening-adherent participants (10.2% vs 7.0%, RFD = 3.2%, 0.2-6.2). Similar trends were observed for tumor stage and mode of detection (mammogram vs lump). Among all participants, those lacking both screening and regular care had larger tumors (21% vs 8%, RR = 2.51, 1.76-3.56) and advanced (3B +) stage (19% vs 6%, RR = 3.15, 2.15-4.63) compared to the referent category (screening-adherent and regular care). Under-use of regular care and screening was more prevalent in socioeconomically disadvantaged areas of North Carolina. CONCLUSIONS Access to regular care is an important safeguard for earlier detection. Our data suggest that health equity interventions should prioritize both primary care and screening.

Abstract
PURPOSE Physical activity (PA) has many health benefits for cancer survivors, but little research has examined patterns and correlates in African American women, who have a higher burden of comorbidities and obesity. We examined PA types and patterns overall and by obesity and comorbidities among long-term (> 5 years) breast cancer survivors. METHODS This cross-sectional study included 323 women who were previous participants of a case-only study in three southeastern states. Women completed a survivorship-focused questionnaire using validated measures to collect data on cancer treatment, PA (recreational, household, transportation) and other lifestyle factors, and comorbidities. Logistic regression models estimated adjusted ORs and 95% CIs for total PA (all three types, categorized as tertiles) and meeting PA guidelines (> 150 min/week of exercise). RESULTS The mean age of women was 59.1 years (range 27.9-79.5). The most frequent PA types (≥ 1/month) included routine household cleaning (92.9%), shopping (94.7%), walking slowly (42.1%), and walking briskly (40.6%). Less than 40% met PA guidelines. Women with more total comorbidities, arthritis, and obesity had lower levels of total PA (minutes/week) and/or recreational PA. In adjusted models, BMI ≥ 35 kg/m2 was associated with reduced odds of total PA (OR = 0.33, 95% CI 0.12-0.88, highest tertile). Arthritis was associated with reduced odds of meeting PA guidelines (OR = 0.61, 95% CI 36-1.05). CONCLUSIONS Close to 60% of African American breast cancer survivors did not meet PA guidelines based on recreational PA participation. Household PA was an important source of PA. Comorbidities and obesity were associated with both reduced total PA and not meeting PA guidelines.

Abstract
INTRODUCTION Racial disparities in breast cancer treatment contribute to Black women having the worst breast cancer survival rates in the U.S. We investigated whether differences in receipt of optimal locoregional treatment (OLT), defined as receipt of mastectomy, breast-conserving surgery, or no surgery when contraindicated, existed between Black and White women with early-stage breast cancer from 2008-2018. METHODS In this retrospective cohort study, data from the Surveillance, Epidemiology, and End Results (SEER) Program Incidence Database was utilized to identify tumor cases from Black and White women aged 20-64 years old with stage I-II breast cancer. Logistic regression analyses were used to evaluate the associations between race and receipt of OLT as well as potential effect modification by tumor characteristics, and year of diagnosis. RESULTS Among 177,234 women diagnosed with early-stage breast tumors, disparities in OLT between Black and White women were present from 2008-2010 (2008: 82.1% Black vs. 85.7% White, p<0.001; 2009: 82.1% Black vs. 85.8% White, p<0.001; 2010: 82.2% Black vs. 87.2% White, p<0.001). This disparity was eliminated between 2010-2011 (86.3% Black vs. 87.5% White, p = 0.15), and did not reoccur during the remainder of the study period. From 2010-2011, more Black women received radiation therapy following breast-conserving surgery (43.4% to 48.9%; p = 0.001), which accounted for an overall increased receipt of OLT. CONCLUSION Increased receipt of radiation therapy with breast-conserving surgery appeared to drive a substantial increase in OLT for Black women from 2010-2011 that lasted throughout the study period. Further research on the underlying mechanisms that reduced this disparity is warranted.

Advancing health equity through implementation science: Identifying and examining measures of the outer setting. Soc Sci Med 2023; 331:116095. [PMID: 37473542 PMCID: PMC10530521 DOI: 10.1016/j.socscimed.2023.116095] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/27/2022] [Revised: 06/07/2023] [Accepted: 07/13/2023] [Indexed: 07/22/2023]
Abstract
BACKGROUND Implementation science (IS) could accelerate progress toward achieving health equity goals. However, the lack of attention to the outer setting where interventions are implemented limits applicability and generalizability of findings to different populations, settings, and time periods. We developed a data resource to assess outer setting across seven centers funded by the National Cancer Institute's IS Centers in Cancer Control (ISC3) Network Program. OBJECTIVE To describe the development of the Outer Setting Data Resource and characterize the county-level outer context across Centers. METHODS Our Data Resource captures seven key environments, including: (1) food; (2) physical; (3) economic; (4) social; (5) health care; (6) cancer behavioral and screening; and (7) cancer-related policy. Data were obtained from public sources including the US Census and American Community Survey. We present medians and interquartile ranges based on the distribution of all counties in the US, all ISC3 centers, and within each Center for twelve selected measures. Distributions of each factor are compared with the national estimate using single sample sign tests. RESULTS ISC3 centers' catchment areas include 458 counties and over 126 million people across 28 states. The median percentage of population living within ½ mile of a park is higher in ISC3 counties (38.0%, interquartile range (IQR): 16.0%-59.0%) compared to nationally (18.0%, IQR: 7.0%-38.0%; p < 0.0001). The median percentage of households with no broadband access is significantly lower in ISC3 counties (28.4%, IQR: 21.4%-35.6%) compared the nation overall (32.8%, IQR: 25.8%-41.2%; p < 0.0001). The median unemployment rate was significantly higher in ISC3 counties (5.2%, IQR: 4.1%-6.4%) compared to nationally (4.9%, 3.6%-6.3%, p = 0.0006). CONCLUSIONS Our results indicate that the outer setting varies across Centers and often differs from the national level. These findings demonstrate the importance of assessing the contextual environment in which interventions are implemented and suggest potential implications for intervention generalizability and scalability.

Abstract
African American (AA) women in the United States have a 40% higher breast cancer mortality rate than Non-Hispanic White (NHW) women. The survival disparity is particularly striking among (estrogen receptor positive) ER+ breast cancer cases. The purpose of this study is to examine whether there are racial differences in metabolic pathways typically activated in patients with ER+ breast cancer. We collected pretreatment plasma from AA and NHW ER+ breast cancer cases (AA n = 48, NHW n = 54) and cancer-free controls (AA n = 100, NHW n = 48) to conduct an untargeted metabolomics analysis using gas chromatography mass spectrometry (GC-MS) to identify metabolites that may be altered in the different racial groups. Unpaired t-test combined with multiple feature selection and prediction models were employed to identify race-specific altered metabolic signatures. This was followed by the identification of altered metabolic pathways with a focus in AA patients with breast cancer. The clinical relevance of the identified pathways was further examined in PanCancer Atlas breast cancer data set from The Cancer Genome Atlas Program (TCGA). We identified differential metabolic signatures between NHW and AA patients. In AA patients, we observed decreased circulating levels of amino acids compared to healthy controls, while fatty acids were significantly higher in NHW patients. By mapping these metabolites to potential epigenetic regulatory mechanisms, this study identified significant associations with regulators of metabolism such as methionine adenosyltransferase 1A (MAT1A), DNA Methyltransferases and Histone methyltransferases for AA individuals, and Fatty acid Synthase (FASN) and Monoacylglycerol lipase (MGL) for NHW individuals. Specific gene Negative Elongation Factor Complex E (NELFE) with histone methyltransferase activity, was associated with poor survival exclusively for AA individuals. We employed a comprehensive and novel approach that integrates multiple machine learning and statistical methods, coupled with human functional pathway analyses. The metabolic profile of plasma samples identified may help elucidate underlying molecular drivers of disproportionately aggressive ER+ tumor biology in AA women. It may ultimately lead to the identification of novel therapeutic targets. To our knowledge, this is a novel finding that describes a link between metabolic alterations and epigenetic regulation in AA breast cancer and underscores the need for detailed investigations into the biological underpinnings of breast cancer health disparities.

Abstract
BACKGROUND Triple-negative breast cancer (TBNC) is an aggressive breast cancer subtype with a poor prognosis. Shugoshin-1 (SGO1) protects chromatids from early separation. Previous studies from our group have demonstrated that transient SGO1 downregulation suppresses early stages of metastasis (the epithelial-to-mesenchymal transition, or EMT, cell invasion, and cell migration) in TNBC cells. Thus, the inhibition of SGO1 activity may represent a potential therapeutic intervention against cancers that progress to metastasis. Therefore, we aimed to investigate the effects of sustained shRNA-mediated SGO1 downregulation on tumor growth and metastasis in TBNC. To that end, female NOD-SCID Gamma (NSG) mice were injected with 2.5 × 106 shRNA Control (n = 10) or shRNA SGO1 (n = 10) MDA-MB-231 cells. After eight weeks, the number of mice with metastasis to the lymph nodes was calculated. Primary and metastatic tumors, as well as lung and liver tissue, were harvested, measured, sectioned, and stained with hematoxylin and eosin (H&E) stain. RESULTS Tumor growth and metastasis to the lymph nodes and lungs were significantly reduced in the shRNA SGO1-treated mice group, while metastasis to the liver tends to be lower in cells with downregulated SGO1, but it did not reach statistical significance. Furthermore, sustained SGO1 downregulation significantly reduced cell proliferation, cell migration, and invasion which correlated with lower levels of Snail, Slug, MMP2, MMP3, and MMP9. CONCLUSION The supression of SGO1 activity in TNBC harboring dysregulated expression of SGO1 may be a potential target for preventing breast cancer growth and metastasis.

Lower breast cancer survival among Black women in Brazil: a population-based retrospective study. Public Health 2023; 217:190-195. [PMID: 36907028 DOI: 10.1016/j.puhe.2023.02.004] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/19/2022] [Revised: 01/29/2023] [Accepted: 02/02/2023] [Indexed: 03/12/2023]
Abstract
OBJECTIVES To analyze the rates of breast cancer survival among Black and White women according to age and stage at diagnosis. STUDY DESIGN A retrospective cohort study. METHODS The study examined women registered in the population-based cancer registry of Campinas in 2010-2014. The primary variable was the declared race (White or Black). Other races were excluded. Data were linked with the Mortality Information System, and missing information was accessed by active search. Overall survival (OS) was calculated by the Kaplan-Meier method, comparisons were done by chi-squared tests, and hazard ratios were examined by Cox regression. RESULTS The total numbers of new cases of staged breast cancer among Black and White women were 218 and 1522 cases, respectively. The rates of stages III/IV were 35.5% among White women and 43.1% among Black women (P = 0.024). The frequencies among White and Black women under 40 years old were 8.0% and 12.4% (P = 0.031), 19.6% and 26.6% (P = 0.016) for ages of 40-49 years, and 23.8% and 17.4% (P = 0.037) for ages of 60-69 years, respectively. The mean OS was 7.5 years (7.0; 8.0) among Black women and 8.4 years (8.2; 8.5) among White women. The 5-year OS was 72.3% among Black women and 80.5% among White women (P = 0.001). Black women had an age-adjusted risk of death that was 1.7 times higher (1.33; 2.20). The risk was 6.4 times higher for diagnoses in stage 0 (1.65; 24.90) and 1.5 times for diagnoses in stage IV (1.04; 2.17). CONCLUSION The 5-year OS for women with breast cancer was significantly lower among Black women than White women. Black women were more frequently diagnosed in stages III/IV, and their age-adjusted risk of death was 1.7 times higher. Differences in access to care may explain these differences.

Racial, ethnic and socioeconomic disparities in diagnosis, treatment, and survival of patients with breast cancer. Am J Surg 2023; 225:154-161. [PMID: 36030101 DOI: 10.1016/j.amjsurg.2022.07.003] [Citation(s) in RCA: 5] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/22/2022] [Revised: 06/07/2022] [Accepted: 07/14/2022] [Indexed: 12/30/2022]
Abstract
BACKGROUND The objective of this study was to determine the influence of race/ethnicity and socioeconomic status (SES) on breast cancer outcomes. METHODS A retrospective analysis was performed of Non-Hispanic Black (NHB), Non-Hispanic White (NHW), and Hispanic patients with non-metastatic breast cancer in the SEER cancer registry between 2007 and 2016. RESULTS A total of 382,975 patients were identified. On multivariate analysis, NHB (OR 1.18, 95%CI: 1.15-1.20) and Hispanic (OR 1.20, 95%CI: 1.17-1.22) patients were more likely to present with higher stage disease than NHW patients. There was an increased likelihood of not undergoing breast-reconstruction for NHB (OR 1.07, 95%CI: 1.03-1.11) and Hispanic patients (OR 1.60, 95%CI 1.54-1.66). NHB patients had increased hazard for all-cause mortality (HR: 1.13, 95%CI 1.10-1.16). All-cause mortality increased across SES categories (lower SES: HR 1.33, 95%CI 1.30-1.37, middle SES: HR 1.20, 95%CI 1.17-1.23). CONCLUSIONS This population-based analysis confirms worse disease presentation, access to surgical therapy, and survival across racial, ethnic, and socioeconomic factors. These disparities were compounded across worsening SES and insurance coverage.

Abstract
PURPOSE Disparities in breast cancer survival have been observed within marginalized racial/ethnic groups and within the rural-urban continuum for decades. We examined whether there were differences among the intersectionality of race/ethnicity and rural residence on breast cancer outcomes. METHODS We performed a retrospective analysis among 739,448 breast cancer patients using Surveillance Epidemiology and End Results (SEER) 18 registries years 2000 through 2016. We conducted multilevel logistic-regression and Cox proportional hazards models to estimate adjusted odds ratios (AORs) and hazard ratios (AHRs), respectively, for breast cancer outcomes including surgical treatment, radiation therapy, chemotherapy, late-stage disease, and risk of breast cancer death. Rural was defined as 2013 Rural-Urban Continuum Codes (RUCC) of 4 or greater. RESULTS Compared with non-Hispanic white-urban (NH-white-U) women, NH-black-U, NH-black-rural (R), Hispanic-U, and Hispanic-R women, respectively, were at increased odds of no receipt of surgical treatment (NH-black-U, AOR = 1.98, 95% CI 1.91-2.05; NH-black-R, AOR = 1.72, 95% CI 1.52-1.94; Hispanic-U, AOR = 1.58, 95% CI 1.52-1.65; and Hispanic-R, AOR = 1.40, 95% CI 1.18-1.67), late-stage diagnosis (NH-black-U, AOR = 1.32, 95% CI 1.29-1.34; NH-black-R, AOR = 1.29, 95% CI 1.22-1.36; Hispanic-U, AOR = 1.25, 95% CI 1.23-1.27; and Hispanic-R, AOR = 1.17, 95% CI 1.08-1.27), and increased risks for breast cancer death (NH-black-U, AHR = 1.46, 95% CI 1.43-1.50; NH-black-R, AHR = 1.42, 95% CI 1.32-1.53; and Hispanic-U, AHR = 1.10, 95% CI 1.07-1.13). CONCLUSION Regardless of rurality, NH-black and Hispanic women had significantly increased odds of late-stage diagnosis, no receipt of treatment, and risk of breast cancer death.

Abstract
Molecular epidemiology evidence indicates racial and ethnic differences in the aggressiveness and survival of breast cancer. Hispanics/Latinas (H/Ls) and non-Hispanic Black women (NHB) are at higher risk of breast cancer (BC)-related death relative to non-Hispanic white (NHW) women in part because they are diagnosed with hormone receptor-negative (HR) subtype and at higher stages. Since the cell cycle is one of the most commonly deregulated cellular processes in cancer, we propose that the mitotic kinases TTK (or Mps1), TBK1, and Nek2 could be novel targets to prevent breast cancer progression among NHBs and H/Ls. In this study, we calculated levels of TTK, p-TBK1, epithelial (E-cadherin), mesenchymal (Vimentin), and proliferation (Ki67) markers through immunohistochemical (IHC) staining of breast cancer tissue microarrays (TMAs) that includes samples from 6 regions in the Southeast of the United States and Puerto Rico -regions enriched with NHB and H/L breast cancer patients. IHC analysis showed that TTK, Ki67, and Vimentin were significantly expressed in triple-negative (TNBC) tumors relative to other subtypes, while E-cadherin showed decreased expression. TTK correlated with all of the clinical variables but p-TBK1 did not correlate with any of them. TCGA analysis revealed that the mRNA levels of multiple mitotic kinases, including TTK, Nek2, Plk1, Bub1, and Aurora kinases A and B, and transcription factors that are known to control the expression of these kinases (e.g. FoxM1 and E2F1-3) were upregulated in NHBs versus NHWs and correlated with higher aneuploidy indexes in NHB, suggesting that these mitotic kinases may be future novel targets for breast cancer treatment in NHB women.

Abstract
The survival for breast cancer (BC) is improving but remains lower in Black women than White women. A number of factors potentially drive the racial differences in BC outcomes. The aim of our study was to determine if insulin resistance (defined as homeostatic model assessment for insulin resistance (HOMA-IR)), mediated part of the relationship between race and BC prognosis (defined by the improved Nottingham prognostic index (iNPI)). We performed a cross-sectional study, recruiting self-identified Black and White women with newly diagnosed primary invasive BC from 10 US hospitals between March 2013 and February 2020. Survey, anthropometric, laboratory, and tumor pathology data were gathered, and we compared the results between Black and White women. We calculated HOMA-IR as well as iNPI scores and examined the associations between HOMA-IR and iNPI. After exclusions, the final cohort was 1206: 911 (76%) White and 295 (24%) Black women. Metabolic syndrome and insulin resistance were more common in Black than White women. Black women had less lobular BC, three times more triple-negative BC, and BCs with higher stage and iNPI scores than White women (P < 0.001 for all comparisons). Fewer Black women had BC genetic testing performed. HOMA-IR mediated part of the association between race and iNPI, particularly in BCs that carried a good prognosis and were hormone receptor (HR)-positive. Higher HOMA-IR scores were associated with progesterone receptor-negative BC in White women but not Black women. Overall, our results suggest that HOMA-IR contributes to the racial disparities in BC outcomes, particularly for women with HR-positive BCs.

Abstract
Breast cancer is the most common noncutaneous malignancy affecting women in the United States, with >245,000 cases diagnosed annually. Breast cancer mortality rates have continued to trend down in the past three decades, yet racial/ethnic disparities persist, with the worst mortality rates seen in Black women. Of note, when compared by race, this downward trend is also trailing in Black women. Survival after breast cancer is mainly driven by factors related to early detection and effective therapy. These factors can be grouped into "biological" such as age, genetic mutations, tumor characteristics; and "social" such as education, income, access to care. There have been studies attributing racial disparities solely to biological factors, and there are those attributing the disparities to social factors alone. Although the exact mechanism is unclear, a relationship between both factors as relates to racial disparities in breast cancer outcomes has been demonstrated. In this report, we review factors contributing to the increased morbidity and mortality for breast cancer in Black women and explore sociological relationships. Facing the worst poverty rates compared with other races, Black women are inevitably more likely to be uninsured, have limited access to quality education, and have fewer financial resources. The goal of this review was to elucidate the complex interplay between biological and social factors contributing to racial disparities in breast cancer outcomes. We conclude by emphasizing the need for interventions made at both local and national levels.

Abstract
BACKGROUND Differential access to quality care is associated with racial disparities in ovarian cancer survival. Few studies have examined the association of multiple healthcare access (HCA) dimensions with racial disparities in quality treatment metrics, that is, primary debulking surgery performed by a gynecologic oncologist and initiation of guideline-recommended systemic therapy. METHODS We analyzed data for patients with ovarian cancer diagnosed from 2008 to 2015 in the Surveillance, Epidemiology, and End Results-Medicare database. We defined HCA dimensions as affordability, availability, and accessibility. Modified Poisson regressions with sandwich error estimation were used to estimate the relative risk (RR) for quality treatment. RESULTS The study cohort was 7% NH-Black, 6% Hispanic, and 87% NH-White. Overall, 29% of patients received surgery and 68% initiated systemic therapy. After adjusting for clinical variables, NH-Black patients were less likely to receive surgery [RR, 0.83; 95% confidence interval (CI), 0.70-0.98]; the observed association was attenuated after adjusting for healthcare affordability, accessibility, and availability (RR, 0.91; 95% CI, 0.77-1.08). Dual enrollment in Medicaid and Medicare compared with Medicare only was associated with lower likelihood of receiving surgery (RR, 0.86; 95% CI, 0.76-0.97) and systemic therapy (RR, 0.94; 95% CI, 0.92-0.97). Receiving treatment at a facility in the highest quartile of ovarian cancer surgical volume was associated with higher likelihood of surgery (RR, 1.12; 95% CI, 1.04-1.21). CONCLUSIONS Racial differences were observed in ovarian cancer treatment quality and were partly explained by multiple HCA dimensions. IMPACT Strategies to mitigate racial disparities in ovarian cancer treatment quality must focus on multiple HCA dimensions. Additional dimensions, acceptability and accommodation, may also be key to addressing disparities.

Abstract
BACKGROUND Prior studies of breast cancer disparities have focused primarily on differences between Black and White women, yet contemporary patterns of disparity for other groups are not well understood. We examine breast cancer disparities by stage at diagnosis across nine racial and ethnic groups. METHODS The SEER 18 registries identified 841,975 women diagnosed with breast cancer from 2000 to 2017. Joinpoint models assessed trends in diagnosis stage and survival. Multivariable logistic regression evaluated associations between race/ethnicity and diagnosis stage. Multivariable Cox models compared survival of groups by stage and molecular subtype. RESULTS Black, American Indian, Southeast Asian, South Asian, Pacific Islander, and Hispanic women were less likely than white women to be diagnosed with early stage breast cancer. Among those diagnosed at early stage, Hispanic, American Indian, Pacific Islander and Black women were 9%, 14%, 22%, and 39% (respectively) more likely than White women to die from breast cancer, whereas Asian subgroups had lower risk of death. Among those diagnosed at late stage, Black women were 18% more likely than White counterparts to die from breast cancer, and survival disparities for Black women persisted across all subtypes and stages, (except late stage HR-/HER2-). East Asian women with early stage HR+/HER2- tumors had better survival than White women. CONCLUSIONS Persistent disparities in early detection and survival of breast cancer demand further work to address and reduce disparities across the cancer continuum. IMPACT Results have implications for efforts to reduce entrenched racial and ethnic disparities in breast cancer early detection and survival.

Abstract
The difference in cancer morbidity and mortality between individuals of different racial groups is complex. Health disparities provide a framework to explore potential connections between poor outcomes and individuals of different racial backgrounds. This study identifies genomic changes in African-American patients with gynecologic malignancies, a population with well-established disparities in outcomes. Our data explore whether social health disparities might mediate interactions between the environment and tumor epigenomes and genomes that can be identified. Using The Cancer Genetic Ancestry Atlas, which encodes data from The Cancer Genome Atlas by ancestry and allows for systematic analyses of sequencing data by racial group, we performed large-scale, comparative analyses to identify novel targets with alterations in methylation, transcript, and microRNA expression between tumors from women of European American or African American racial groups across all gynecologic malignancies. We identify novel discrete genomic changes in these complex malignancies and suggest a framework for identifying novel therapeutic targets for future investigation.

Abstract
PURPOSE Many studies have demonstrated disparities in breast cancer (BC) incidence and mortality among Black women. We hypothesized that in Pennsylvania (PA), a large economically diverse state, BC diagnosis and mortality would be similar among races when stratified by a municipality's median income. METHODS We collected the frequencies of BC diagnosis and mortality for years 2011-2015 from the Pennsylvania Cancer Registry and demographics from the 2010 US Census. We analyzed BC diagnoses and mortalities after stratifying by median income, municipality size, and race with univariable and multivariable logistic regression models. RESULTS In this cohort, of 5,353,875 women there were 54,038 BC diagnoses (1.01% diagnosis rate) and 9,828 BC mortalities (0.18% mortality rate). Unadjusted diagnosis rate was highest among white women (1.06%) but Black women had a higher age-adjusted diagnosis rate (1.06%) than white women (1.02%). Race, age and income were all significantly associated with BC diagnosis, but there were no differences in BC diagnosis between white and Black women across all levels of income in the multivariable model. BC mortality was highest in Black women, a difference which persisted when adjusted for age. Black women 35 years and older had a higher mortality rate in all income quartiles. CONCLUSION We found that in PA, age, race and income are all associated with BC diagnosis and mortality with noteworthy disparities for Black women. Continued surveillance of differences in both breast cancer diagnosis and mortality, and targeted interventions related to education, screening and treatment may help to eliminate these socioeconomic and racial disparities.

Association between Neighborhood Social Deprivation and Stage at Diagnosis among Breast Cancer Patients in South Carolina. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2021; 18:ijerph182211824. [PMID: 34831579 PMCID: PMC8625868 DOI: 10.3390/ijerph182211824] [Citation(s) in RCA: 11] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 10/17/2021] [Revised: 11/01/2021] [Accepted: 11/04/2021] [Indexed: 11/25/2022]
Abstract
The purpose of this study was to examine the association between neighborhood social deprivation and individual-level characteristics on breast cancer staging in African American and white breast cancer patients. We established a retrospective cohort of patients with breast cancer diagnosed from 1996 to 2015 using the South Carolina Central Cancer Registry. We abstracted sociodemographic and clinical variables from the registry and linked these data to a county-level composite that captured neighborhood social conditions-the social deprivation index (SDI). Data were analyzed using chi-square tests, Student's t-test, and multivariable ordinal regression analysis to evaluate associations. The study sample included 52,803 female patients with breast cancer. Results from the multivariable ordinal regression model demonstrate that higher SDI (OR = 1.06, 95% CI: 1.02-1.10), African American race (OR = 1.35, 95% CI: 1.29-1.41), and being unmarried (OR = 1.17, 95% CI: 1.13-1.22) were associated with a distant stage at diagnosis. Higher tumor grade, younger age, and more recent year of diagnosis were also associated with distant-stage diagnosis. As a proxy for neighborhood context, the SDI can be used by cancer registries and related population-based studies to identify geographic areas that could be prioritized for cancer prevention and control efforts.

Abstract
INTRODUCTION More than a third of hospitalized women are overdue or nonadherent to breast cancer screening guidelines, and almost a third of them are also at high risk for developing breast cancer. The purpose of this study is to evaluate the feasibility of coordinating inpatient breast cancer screening mammography for these women before their discharge from the hospital. METHODS A prospective intervention study was conducted among 101 nonadherent women aged 50-74 years who were hospitalized to a general medicine service. Sociodemographic, reproductive history, family history of breast cancer, and medical comorbidities data were collected for all patients from January 2015 to October 2016. The data were analyzed in March 2018. Fisher's exact tests and unpaired t-tests were utilized to compare the characteristics of the study population. RESULTS Of the 101 women enrolled who were nonadherent to breast cancer screening recommendations, their mean age was 59.3 (SD=6) years, the mean 5-year Gail risk score was 1.63 (SD=0.69), and 29% of the women were African American. Almost 80% (n=79) underwent inpatient screening mammography. All women who underwent screening mammography during their inpatient stay were extremely satisfied with the experience. The convenience of having screening mammography while hospitalized was reported to be a major facilitator of completing the overdue screening. All nurses (100%) taking care of these women believed that this practice should become part of the standard of care, and most hospitalist physicians (66%) agreed that this practice is feasible. CONCLUSIONS This study shows that it is possible to coordinate mammography for hospitalized women who were overdue for screening and at high risk for developing breast cancer. TRIAL REGISTRATION This study is registered at www.clinicaltrials.gov NCT04164251.

Abstract
OBJECTIVE To study the impact of socio-economic status and ethno-racial strata on excess mortality hazard and net survival of women with breast cancer in two Brazilian state capitals. METHOD We conducted a survival analysis with individual data from population-based cancer registries including women with breast cancer diagnosed between 1996 and 2012 in Aracaju and Curitiba. The main outcomes were the excess mortality hazard (EMH) and net survival. The associations of age, year of diagnosis, disease stage, race/skin colour and socioeconomic status (SES) with the excess mortality hazard and net survival were analysed using multi-level spline regression models, modelled as cubic splines with knots at 1 and 5 years of follow-up. RESULTS A total of 2045 women in Aracaju and 7872 in Curitiba were included in the analyses. The EMH was higher for women with lower SES and for black and brown women in both municipalities. The greatest difference in excess mortality was seen between the most deprived women and the most affluent women in Curitiba, hazard ratio (HR) 1.93 (95%CI 1.63-2.28). For race/skin colour, the greatest ratio was found in Curitiba (HR 1.35, 95%CI 1.09-1.66) for black women compared with white women. The most important socio-economic difference in net survival was seen in Aracaju. Age-standardised net survival at five years was 55.7% for the most deprived women and 67.2% for the most affluent. Net survival at eight years was 48.3% and 61.0%, respectively. Net survival in Curitiba was higher than in Aracaju in all SES groups." CONCLUSION Our findings suggest the presence of contrasting breast cancer survival expectancy in Aracaju and Curitiba, highlighting regional inequalities in access to health care. Lower survival among brown and black women, and those in lower SES groups indicates that early detection, early diagnosis and timely access to treatment must be prioritized to reduce inequalities in outcome among Brazilian women.

Abstract
BACKGROUND Younger breast cancer survivors face unique challenges, and research is needed to better understand how to optimize their quality of life (QoL) and satisfaction with life (SwL). OBJECTIVE The aim of this study was to examine a biopsychosocial model of QoL and SwL in young breast cancer survivors. Biological, psychological, and social/practical factors were hypothesized to be associated with both distressing and adaptive reactions during survivorship, which in turn were hypothesized to be associated with QoL and SwL. METHODS Young (age = 19-45 years at diagnosis) breast cancer survivors (N = 284) completed an online survey assessing demographic and biopsychosocial factors, QoL, and SwL. Latent variables were created for adaptive and distressing reactions, and structural equation modeling was used to test the hypothesized relationships. RESULTS The model fit the data (χ2(100) = 332.92, P < .001, comparative fit index = 0.86, root mean square error of approximation = 0.09, standardized root mean square residual = 0.05) and accounted for large proportions of variance in QoL (R2 = 0.86) and SwL (R2 = 0.62). Social support, parenting concerns, and fertility concerns each significantly predicted adjustment. Adaptive reactions positively predicted SwL (β = 0.58, P < .001) but not QoL. Distressing reactions negatively predicted SwL (β = -0.26, P < .01) and QoL (β = -0.87, P < .001). CONCLUSIONS Adjustment in survivorship mediated the association of social support, parenting concerns, and fertility concerns on QoL and SwL in young breast cancer survivors. IMPLICATIONS FOR PRACTICE To support the psychological adjustment of young breast cancer survivors, attention should be given to survivors' social context including survivors' available social support and their concerns about fertility and parenting.

Abstract
INTRODUCTION Less than 40% of patients with ovarian cancer (OC) in the USA receive stage-appropriate guideline-adherent surgery and chemotherapy. Black patients with cancer report greater depression, pain and fatigue than white patients. Lack of access to healthcare likely contributes to low treatment rates and racial differences in outcomes. The Ovarian Cancer Epidemiology, Healthcare Access and Disparities study aims to characterise healthcare access (HCA) across five specific dimensions-Availability, Affordability, Accessibility, Accommodation and Acceptability-among black, Hispanic and white patients with OC, evaluate the impact of HCA on quality of treatment, supportive care and survival, and explore biological mechanisms that may contribute to OC disparities. METHODS AND ANALYSIS We will use the Surveillance Epidemiology and Ends Results dataset linked with Medicare claims data from 9744 patients with OC ages 65 years and older. We will recruit 1641 patients with OC (413 black, 299 Hispanic and 929 white) from cancer registries in nine US states. We will examine HCA dimensions in relation to three main outcomes: (1) receipt of quality, guideline adherent initial treatment and supportive care, (2) quality of life based on patient-reported outcomes and (3) survival. We will obtain saliva and vaginal microbiome samples to examine prognostic biomarkers. We will use hierarchical regression models to estimate the impact of HCA dimensions across patient, neighbourhood, provider and hospital levels, with random effects to account for clustering. Multilevel structural equation models will estimate the total, direct and indirect effects of race on treatment mediated through HCA dimensions. ETHICS AND DISSEMINATION Result dissemination will occur through presentations at national meetings and in collaboration with collaborators, community partners and colleagues across othercancer centres. We will disclose findings to key stakeholders, including scientists, providers and community members. This study has been approved by the Duke Institutional Review Board (Pro00101872). Safety considerations include protection of patient privacy. All disseminated data will be deidentified and summarised.

Changing trends and disparities in 5-year overall survival of women with invasive breast cancer in the United States, 1975-2015. Am J Cancer Res 2021; 11:3201-3211.

Abstract
Relative survival is the ratio of overall survival (OS) over survival of the general population, and widely used in epidemiological studies. But it is artificially higher than OS and thus inferior to OS for cancer prognostication of individual patients. Moreover, trend-changes and disparities in OS of breast cancer are unclear while the relative survival of breast cancer has been reported on a regular basis. Therefore, we estimated trends in age-standardized 5-year OS of invasive breast cancer, using data from the Surveillance, Epidemiology, and End Results (SEER) cancer registry program and piecewise-linear regression models. Among 188,052 women with breast cancer diagnosed during 2007-2010 (SEER-18, 155,515 [79.3%] survived by year 5), the 5-year OS significantly differed by age, histology, tumor grade, tumor stage, hormone receptors, race/ethnicity, insurance status, region, rural-urban continuum and selected county-attributes. Among 469,498 women with breast cancer diagnosed during 1975-2010 (SEER-9) in the U.S., we observed an upward trend in the age-standardized 5-year OS (stage- and race/ethnicity-adjusted annual percentage change = 0.97 [95% CI, 0.76-1.18]). The 36-year trends/slopes in age-standardized 5-year OS of breast cancer differed by histology, tumor grade, stage, race/ethnicity, region and socioeconomic attributes of the patient's residence-county, but not by those of rural-urban continuum. The 3-joinpoint model on the 36-year trend identified significant slope changes in 1983, 1987 and 2000, with the largest slope (2.5%/year) during 1983-1987. In conclusion, we here show trends in the age-standardized 5-year OS among U.S. women with breast cancer changed in diagnosis-years of 1983, 1987 and 2000, and differed by tumor characteristics and race/ethnicity. More efforts are needed to understand the trend changes and to address the OS disparities of breast cancers.

Abstract
Biological therapies against breast cancer patients with tumors positive for the estrogen and progesterone hormone receptors and Her2 amplification have greatly improved their survival. However, to date, there are no effective biological therapies against breast cancers that lack these three receptors or triple-negative breast cancers (TNBC). TNBC correlates with poor survival, in part because they relapse following chemo- and radio-therapies. TNBC is intrinsically aggressive since they have high mitotic indexes and tend to metastasize to the central nervous system. TNBCs are more likely to display centrosome amplification, an abnormal phenotype that results in defective mitotic spindles and abnormal cytokinesis, which culminate in aneuploidy and chromosome instability (known causes of tumor initiation and chemo-resistance). Besides their known role in cell cycle control, mitotic kinases have been also studied in different types of cancer including breast, especially in the context of epithelial-to-mesenchymal transition (EMT). EMT is a cellular process characterized by the loss of cell polarity, reorganization of the cytoskeleton, and signaling reprogramming (upregulation of mesenchymal genes and downregulation of epithelial genes). Previously, we and others have shown the effects of mitotic kinases like Nek2 and Mps1 (TTK) on EMT. In this review, we focus on Aurora A, Aurora B, Bub1, and highly expressed in cancer (Hec1) as novel targets for therapeutic interventions in breast cancer and their effects on EMT. We highlight the established relationships and interactions of these and other mitotic kinases, clinical trial studies involving mitotic kinases, and the importance that represents to develop drugs against these proteins as potential targets in the primary care therapy for TNBC.

Abstract
Breast cancer presents high incidence and mortality rates, being considered an important public health issue. Analyze the spatial distribution pattern of late stage diagnosis and mortality for breast cancer and its correlation with socioeconomic and health service offer-related population indicators. Ecological study, developed with 161 Intermediate Region of Urban Articulation (IRUA). Mortality data were collected from the Mortality Information System (MIS). Tumor staging data were extracted from the Hospital Cancer Registry (HCR). Socioeconomic variables were obtained from the Atlas of Human Development in Brazil; data on medical density and health services were collected from the National Registry of Health Institutions (NRHI) and Supplementary National Health Agency. Global Moran's Index and Local Indicator of Spatial Association (LISA) were utilized to verify the existence of territorial clusters. Multivariate analysis used models with global spatial effects. The proportion of late stage diagnosis of breast cancer was 39.7% (IC 39.4–40.0). The mean mortality rate for breast cancer, adjusted by the standard world population was 10.65 per 100,000 women (± 3.12). The proportion of late stage diagnosis presented positive spatial correlation with Gini’s Index (p = 0.001) and negative with the density of gynecologist doctors (p = 0.009). The adjusted mortality rates presented a positive spatial correlation with the Human Development Index (p<0.001) and density of gynecologist doctors (p<0.001). Socioeconomic and health service offer-related inequalities of the Brazilian territory are determinants of the spatial pattern of breast cancer morbimortality in Brazil.

J Racial Ethn Health Disparities 2021; 8:147-156. [PMID: 32385849 PMCID: PMC7648729 DOI: 10.1007/s40615-020-00766-y] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/23/2019] [Revised: 04/09/2020] [Accepted: 04/22/2020] [Indexed: 12/29/2022]
Abstract
INTRODUCTION Mortality from breast cancer among Black women is 60% greater than that of White women in South Carolina (SC). The aim of this study was to assess racial differences in mortality among Black and White breast cancer patients based on variations in social determinants and access to state-based early detection programs. METHODS We obtained a retrospective record for breast cancer patients diagnosed between 2002 and 2010 from the SC Central Cancer Registry. Mortality was the main outcome while race-stratified Cox proportional hazard models were performed to assess disparities in mortality. We assessed effect modification, and we used an automated backward elimination process to obtain the best fitting models. RESULTS There were 3286 patients of which the majority were White women (2186, 66.52%). Compared with married White women, the adjusted hazard ratio (aHR) for mortality was greatest among Black unmarried women (aHR 2.31, CI 1.83, 2.91). Compared with White women who lived in the Low Country region mortality was greatest among Black women who lived in the Midland (aHR 2.17 CI 1.47, 3.21) and Upstate (aHR 2.96 CI 1.96, 2.49). Mortality was higher among Black women that were not receiving services in the Best Chance Network (BCN) program (aHR 1.70, CI 1.40, 2.04) compared with White women. CONCLUSIONS To reduce the racial disparity gap in survival in SC, Black breast cancer patients who live in the Upstate, are unmarried, and those that are not enrolled in the BCN program may benefit from more intense navigation efforts directed at early detection and linkage to breast cancer treatments.

The Influence of Marital Status on the Survival of Patients with Uveal Melanoma. J Ophthalmol 2021; 2020:7012940. [PMID: 33489340 PMCID: PMC7803291 DOI: 10.1155/2020/7012940] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/10/2020] [Revised: 08/26/2020] [Accepted: 11/12/2020] [Indexed: 12/21/2022] Open
Abstract
Background Uveal melanoma (UM) is the most common primary intraocular tumor in adults and arises from the uvea. Marital status was a vital factor among physical conditions and social networks of cancer patients. Our study aimed to evaluate the impact of marital status on the outcomes among patients with UM. Methods Patients with UM newly diagnosed from 2004 to 2015 were extracted, and the data were extracted from Surveillance, Epidemiology, and End Results (SEER) program. Overall survival (OS) was measured via the log-rank test, as well as cancer-specific survival (CSS) was also calculated via the same method. Cox proportional hazards models were applied to assess whether marital status was related to both OS and CSS. Furthermore, we performed subgroup analysis depending on different sexes and SEER stages. Results In total, 4217 eligible patients were involved. Of these patients, 66.2% (n = 2793) were married, 14.6% (n = 615) were single, and 9.0% (n = 379) were divorced or separated, as well as widowed were 10.2% (n = 430). The 5-year OS of married, single, divorced or separated, and widowed patients was 74.0%, 72.8%, 68.6%, and 55.8%, respectively. The results indicating better OS and CSS occurred among married patients. Other factors such as sex, age at diagnosis, and SEER stage were also correlated with survival in UM patients. Furthermore, subgroup analyses were consistent with the results above. Conclusion Marital status was proved to be an independent prognostic value for survival in UM patients. In addition, contrast to married patients, widowed individuals showed poor OS and CSS at different subgroup analyses.

Breast cancer treatment delays by socioeconomic and health care access latent classes in Black and White women. Cancer 2020; 126:4957-4966. [PMID: 32954493 DOI: 10.1002/cncr.33121] [Citation(s) in RCA: 50] [Impact Index Per Article: 12.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/27/2020] [Revised: 06/10/2020] [Accepted: 07/06/2020] [Indexed: 12/28/2022]
Abstract
BACKGROUND Breast cancer mortality is higher for Black and younger women. This study evaluated 2 possible contributors to disparities-time to treatment and treatment duration-by race and age. METHODS Among 2841 participants with stage I-III disease in the Carolina Breast Cancer Study, we identified groups of women with similar patterns of socioeconomic status (SES), access to care, and tumor characteristics using latent class analysis. We then evaluated latent classes in association with treatment delay (initiation >60 days after diagnosis) and treatment duration (in quartiles by treatment modality). RESULTS Thirty-two percent of younger Black women were in the highest quartile of treatment duration (versus 22% of younger White women). Black women experienced a higher frequency of delayed treatment (adjusted relative frequency difference [RFD], 5.5% [95% CI, 3.2%-7.8%]) and prolonged treatment duration (RFD, 8.8% [95% CI, 5.7%-12.0%]). Low SES was significantly associated with treatment delay among White women (RFD, 3.5% [95% CI, 1.1%-5.9%]), but treatment delay was high at all levels of SES in Black women (eg, 11.7% in high SES Black women compared with 10.6% and 6.7% among low and high SES White women, respectively). Neither SES nor access to care classes were significantly associated with delayed initiation among Black women, but both low SES and more barriers were associated with treatment duration across both groups. CONCLUSIONS Factors that influence treatment timeliness persist throughout the care continuum, with prolonged treatment duration being a sensitive indicator of differences by race, SES, and care barriers.

Papautsky EL, Hamlish T. Patient-reported treatment delays in breast cancer care during the COVID-19 pandemic. Breast Cancer Res Treat 2020; 184:249-254. [PMID: 32772225 PMCID: PMC7415197 DOI: 10.1007/s10549-020-05828-7] [Citation(s) in RCA: 138] [Impact Index Per Article: 34.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/06/2020] [Accepted: 07/20/2020] [Indexed: 01/21/2023]
Abstract
PURPOSE The coronavirus disease (COVID-19) pandemic has had a profound impact on cancer care in the US Guidelines focused on the management of COVID-19, rather than healthcare needs of breast cancer patients requiring access to crucial services. This US survey of breast cancer survivors characterizes treatment delays early period in the pandemic. METHODS We developed a survey and administered it to 609 adult breast cancer survivors in the US. We used snowball sampling with invitations distributed via social media. We used logistic regression to select a model of delay from a pool of independent variables including race, cancer stage, site of care, health insurance, and age. We used descriptive statistics to characterize delay types. RESULTS Forty-four percent of participants reported cancer care treatment delays during the pandemic. Delays in all aspects of cancer care and treatment were reported. The only variable which had a significant effect was age (97 (.95, 99), p < 0.001) with younger respondents (M = 45.94, SD = 10.31) reporting a higher incidence of delays than older respondents (M = 48.98, SD = 11.10). There was no significant effect for race, insurance, site of care, or cancer stage. CONCLUSIONS Our findings reveal a pervasive impact of COVID-19 on breast cancer care and a gap in disaster preparedness that leaves cancer survivors at risk for poor outcomes. Delays are critical to capture and characterize to help cancer providers and healthcare systems develop effective and patient-tailored processes and strategies to manage cases during the current pandemic wave, subsequent waves, and future disasters.

Abstract
Introduction Breast cancer remains the most commonly diagnosed malignancy in women. It encompasses considerable heterogeneity in pathology, patient clinical characteristics, and outcome. This study describes factors associated with overall survival (OS) of breast cancer in an updated national database. Methods We conducted a retrospective analysis of patients with breast cancer diagnosed between 2004 and 2016 based on the National Cancer Database. Categorical variables were summarized using frequencies/percentages, whereas continuous variables were summarized using the median/interquartile range (IQR). OS was explored using the Kaplan-Meier method. Results Data from n = 2,671,549 patients were analyzed. The median age at diagnosis was 61 years (range 18-90). 75% were non-Hispanic (NH) White; 11% were NH-Black; 4.7% were Hispanic-White; 0.1% were Hispanic-Black; and 3.4% were Asian. Most cases (73%) presented with ductal carcinoma histology; while 15% with lobular carcinoma. Rarer subtypes included epithelial-myoepithelial, fibroepithelial, metaplastic, and mesenchymal tumors. OS was associated with molecular subtype, histologic subtype, and AJCC clinical staging. Survival also correlated with race: a cohort including Asians and Pacific Islanders had the best survival, while Black patients had the worst. Finally, facility type also impacted outcome: patients at academic centers had the best survival, while those at community cancer programs had the worst. Conclusion This large database provides a recent and comprehensive overview of breast cancer over 12 years. Molecular subtype, histologic subtype, stage, race, and facility type were correlated with OS. In addition to the educational perspective of this overview, significant factors impacting the outcome identified here should be considered in future cancer research on disparities.

Abstract
PURPOSE This study explores factors that are associated with the severity of breast cancer (BC) at diagnosis. METHODS Interviews were conducted among women (n = 3326) aged 20-79 diagnosed with BC between 2011 and 2013 in Queensland, Australia. High-severity cancers were defined as either Stage II-IV, Grade 3, or having negative hormone receptors at diagnosis. Logistic regression models were used to estimate odds ratios (ORs) of high severity BC for variables relating to screening, lifestyle, reproductive habits, family history, socioeconomic status, and area disadvantage. RESULTS Symptom-detected women had greater odds (OR 3.38, 2.86-4.00) of being diagnosed with high-severity cancer than screen-detected women. Women who did not have regular mammograms had greater odds (OR 1.78, 1.40-2.28) of being diagnosed with high-severity cancer than those who had mammograms biennially. This trend was significant in both screen-detected and symptom-detected women. Screen-detected women who were non-smokers (OR 1.77, 1.16-2.71), postmenopausal (OR 2.01, 1.42-2.84), or employed (OR 1.46, 1.15-1.85) had greater odds of being diagnosed with high-severity cancer than those who were current smokers, premenopausal, or unemployed. Symptom-detected women being overweight (OR 1.67, 1.31-2.14), postmenopausal (OR 2.01, 1.43-2.82), had hormone replacement therapy (HRT) < 2 years (OR 1.60, 1.02-2.51) had greater odds of being diagnosed with high-severity cancer than those of healthy weight, premenopausal, had HRT > 10 years. CONCLUSION Screen-detected women and women who had mammograms biennially had lower odds of being diagnosed with high-severity breast cancer, which highlighted the benefit of regular breast cancer screening. Women in subgroups who are more likely to have more severe cancers should be particularly encouraged to participate in regular mammography screening.

Abstract
BACKGROUND Race is an important determinant of cancer outcome. The purpose of this study was to identify disparities in clinical presentation, treatment use, and in-hospital outcomes of patients with spinal metastases. METHODS The United States National Inpatient Sample database (2004-2014) was queried to identify patients with metastatic disease and cord compression (MSCC) or spinal pathological fracture. Clinical presentation, type of intervention, and in-hospital outcomes were compared between races/ethnicities. Multivariate logistic regression analyses were performed and adjusted for differences in patient age, sex, insurance status, income quartile, hospital teaching status and size, Charlson comorbidity index, smoking status, tumor type, and neurological status. RESULTS A total of 145,809 patients were identified - 74.8 % Caucasian, 14.1 % African-American, 7.9 % Hispanic, and 3.2 % Asian. Over one-third of patients (38.1 %) presented with MSCC; 35.7 % of Caucasians, 50.3 % of AAs, 41.1 % of Hispanics, and 39.8 % of Asians (p < 0.001). Paralysis affected 8.4 % of all patients; 7.4 % of Caucasians, 12.7 % of AAs, 10.5 % of Hispanics, and 10.0 % of Asians (p < 0.001). For patients with MSCC, multivariate analysis showed that AAs were less likely to undergo surgical intervention (OR 0.71; 95 % CI, 0.62 - 0.82; p < 0.001), significantly more likely to experience a complication (OR 1.25; 95 % CI, 1.12-1.40; p < 0.001), significantly more likely to experience prolonged length of stay (OR 1.22; 95 % CI, 1.08-1.36; p = 0.001), and significantly more likely to experience a non-routine discharge (OR 1.19; 95 % CI, 1.05-1.35; p = 0.007) compared to Caucasians. CONCLUSION Minority groups with spinal metastatic disease may be at a disadvantage compared to Caucasians, with significant disparities found in presenting characteristics, type of intervention, and in-hospital outcomes. Continued efforts to overcome these differences are needed.

Abstract
Purpose of the review Breast cancer incidence and mortality rates are lower in some Hispanic/Latino subpopulations compared to Non-Hispanic White women. However, studies suggest that the risk of breast cancer-specific mortality is higher in US Hispanics/Latinas. In this review we summarized current knowledge on factors associated with breast cancer incidence and risk of mortality in women of Hispanic/Latino origin. Recent findings Associative studies have proposed a multiplicity of factors likely contributing to differences in breast cancer incidence and survival between population groups, including socioeconomic/sociodemographic factors, lifestyle choices as well as access to and quality of care. Reports of association between global genetic ancestry overall as well as subtype-specific breast cancer risk among Hispanic/Latinas suggest that incidence and subtype distribution could result from differential exposure to environmental and lifestyle related factors correlated with genetic ancestry as well as germline genetic variation. Summary Hispanic/Latino in the United States have been largely underrepresented in cancer research. It is important to implement inclusive programs that facilitate the access of this population to health services and that also include education programs for the community on the importance of screening. In addition, it is important to continue promoting the inclusion of Hispanics/Latinos in genomic studies that allow understanding the biological behavior of this disease in the context of all human genetic diversity.

Abstract
BACKGROUND Breast cancer (BC) survivors are at increased risk of cardiovascular disease (CVD) due to shared risk factors with BC and cardiotoxic treatment effects. We aim to investigate racial differences in mortality due to CVD and BC among women diagnosed with invasive BC. METHODS Data from 407 587 non-Hispanic Black (NHB) and White (NHW) women diagnosed with malignant BC (1990-2014) were obtained from the Surveillance, Epidemiology, and End Results database. Cumulative incidence of mortality due to CVD and BC was calculated by race and age (years). Cox models were used to obtain hazard ratios (HR) and 95% confidence intervals (95%CI) for the association of race/ethnicity with cause-specific mortality. RESULTS The 20-year cumulative incidence of CVD-related mortality was higher among younger NHBs than NHWs (e.g. age 55-69: 13.3% vs 8.9%, respectively). NHBs had higher incidence of BC-specific mortality than NHWs, regardless of age. There was a monotonic reduction in CVD-related mortality disparities with increasing age (age <55: HR = 3.71, 95%CI: 3.29, 4.19; age 55-68: HR = 2.31, 95%CI: 2.15, 2.49; age 69+: HR = 1.24, 95%CI: 1.19, 1.30). The hazard of BC-specific mortality among NHBs was approximately twice that of NHWs (e.g. age <55: HR = 1.98, 95%CI: 1.92, 2.04). CONCLUSIONS There are substantial differences in mortality due to CVD and BC between NHB and NHW women diagnosed with invasive BC. Racial differences were greatest among younger women for CVD-related mortality and similar across age groups for BC-specific mortality. Future studies should identify pathways through which race/ethnicity affects cause-specific mortality, to inform efforts towards reducing disparities.

Abstract
Female breast cancer is the most common cancer diagnosed among Alaska Native (AN) women. We examined characteristics of and trends for female breast cancer among AN women. We assessed descriptive statistics, incidence trends (1969-2014), and cause-specific survival for female breast cancers recorded in the Alaska Native Tumor Registry. Results indicated that the majority of breast cancers among AN were diagnosed among women aged over 50 years, at local stage, and with Hormone receptor (HR)+/Human Epidermal Growth Factor (HER) 2- subtype. Five-year average incidence (95% CI) in the most recent time-period (2009-2014) was 145.0/100,000 (130.4, 159.5)); this was not statistically different from the previous time-period. Survival from breast cancer was high and varied by stage and cancer subtype. Hazard of death was greater among those diagnosed with regional/distant/unknown disease, relative to local disease (HR (95%CI): 4.65 (1.66, 12.98)), and higher among those with HER2-/HR- cancers, relative to those with HER2-/HR+ cancers (HR (95%CI): 6.59 (2.23, 19.49)). This study provides a comprehensive description of breast cancer among AN women, providing new and updated information on clinical and demographic factors, cancer incidence trends, regional variations and breast cancer survival.

Abstract
INTRODUCTION To evaluate disparities in breast cancer stage by subtype (categorizations of breast cancer based upon molecular characteristics) in the Delta Regional Authority (Delta), an impoverished region across eight Lower Mississippi Delta Region (LMDR) states with a high proportion of Black residents and high breast cancer mortality rates. METHODS We used population-based cancer registry data from seven of the eight LMDR states to explore breast cancer staging (early and late) differences by subtype between the Delta and non-Delta in the LMDR and between White and Black women within the Delta. Age-adjusted incidence rates and rate ratios were calculated to examine regional and racial differences. Multilevel negative binomial regression models were constructed to evaluate how individual-level and area-level factors affect rates of early- and late-stage breast cancers by subtype. RESULTS For all subtypes combined, there were no Delta/non-Delta differences in early and late stage breast cancers. Delta women had lower rates of hormone-receptor (HR+)/human epidermal growth factor 2 (HER2-) and higher rates of HR-/HER2- (the most aggressive subtype) early and late stage cancers, respectively, but these elevated rates were attenuated in multilevel models. Within the Delta, Black women had higher rates of late-stage breast cancer than White women for most subtypes; elevated late-stage rates of all subtypes combined remained in Black women in multilevel analysis (RR = 1.10; 95% CI = 1.04-1.15). CONCLUSIONS Black women in the Delta had higher rates of late-stage cancers across subtypes. Culturally competent interventions targeting risk-appropriate screening modalities should be scaled up in the Delta to improve early detection.

Abstract
BACKGROUND Few studies have examined whether community factors mediate the relationship between patients surviving cancer and future development of sepsis. We determined the influence of community characteristics upon risk of sepsis after cancer, and whether there are differences by race. METHODS We performed a prospective analysis using data from the REasons for Geographic and Racial Differences in Stroke cohort years 2003 to 2012 complemented with county-level community characteristics from the American Community Survey and County Health Rankings. We categorized those with a self-reported prior cancer diagnosis as "cancer survivors" and those without a history of cancer as "no cancer history." We defined sepsis as hospitalization for a serious infection with ≥2 systemic inflammatory response syndrome criteria. We examined the mediation effect of community characteristics on the association between cancer survivorship and sepsis incidence using Cox proportional hazards models adjusted for age, sex, race, and total number of comorbidities. We repeated analysis stratified by race. RESULTS There were 28 840 eligible participants, of which 2860 (9.92%) were cancer survivors, and 25 289 (90.08%) were no cancer history participants. The only observed community-level mediation effects were from income (% mediated 0.07%; natural indirect effect [NIE] on hazard scale] = 1.001, 95% confidence interval [95% CI]: 1.000-1.005) and prevalence of adult smoking (% mediated = 0.21%; NIE = 1.002, 95% CI: 1.000-1.004). We observed similar effects when stratified by race. CONCLUSION Cancer survivors are at increased risk of sepsis; however, this association is weakly mediated by community poverty and smoking prevalence.

Abstract
BACKGROUND Black women with breast cancer have lower survival rates and higher recurrence rates in comparison with white women. This study compared treatment and survival outcomes for black and white women at a highly specialized tertiary care cancer center. METHODS An institutional review board-approved, retrospective institutional database review was performed to identify all black women treated for invasive breast cancer between 2005 and 2010. Women with a prior history of breast cancer, stage IV cancer, or bilateral breast cancer were excluded. White women had similar exclusion criteria applied and were then matched to black women 1:1 by age and diagnosis year. Clinicopathologic and treatment variables were compared by race. Kaplan-Meier methodology was used to estimate overall survival (OS) and disease-free survival (DFS); a multivariable analysis was conducted with Cox regression models. RESULTS The study group consisted of 1332 women (666 black). The median tumor size was larger in black women (1.6 vs 1.3 cm; P < .001). Black women had more nodal disease (41.1% vs 32%; P < .001) and had tumors that were more frequently an estrogen receptor-negative (32.9% vs 15%; P < .001), progesterone receptor-negative (47.1% vs 30.2%; P < .001), or triple-negative (TN) subtype (24% vs 8.9%; P < .001) in comparison with white women. Black women also had inferior DFS and OS; race was not an independent prognostic indicator in the multivariable analysis. CONCLUSIONS Black women had more advanced disease and adverse prognostic indicators at diagnosis, but race was not an independent predictor of outcome. Black women were significantly more likely to have TN breast cancer. Further research is necessary to understand the differences in tumor biology associated with race.

Abstract
Purpose: To examine the long-term effects of a patient navigation (PN) program for mammography screening tailored to refugee women and to assess screening utilization among these women after PN ended. Methods: We assessed the proportion of patients completing mammography screening during the prior 2 years during 2012–2016 for refugee women who had previously received PN compared with that of English-speaking women cared for at the same health center during the same period, both overall and stratifying by age. We used logistic regression to compare screening completion between refugees and English speakers, adjusting for age, race, insurance status, number of clinic visits, and clustering by primary care physician and to test trends in screening over time. Results: In 2012, the year when the funding for PN ceased, among 126 refugee women eligible for breast cancer screening, mammography screening rates were significantly higher among refugees (90.5%, 95% confidence interval [CI]: 83.5–94.7%) than among English speakers (81.9%, 95% CI: 76.2–86.5%, p=0.006). By 2016, screening rates decreased among refugee women (76.5%, 95% CI: 61.6–86.9%, p=0.023) but were not statistically significantly different from those among English-speaking women (80.5%, 95% CI: 74.4–85.3%, p=0.460). Screening prevalence for refugee women remained above the pre-PN program screening levels, and considerably so in women <50 years. Conclusion: The culturally and language-tailored PN program for refugee women appeared to have persistent effects, with refugee women maintaining similar levels of mammography screening to English-speaking patients 5 years after the PN program's end.

Abstract
BACKGROUND Time to clinical follow-up after an abnormal mammogram may be a significant factor contributing to breast cancer health disparities. OBJECTIVE Evaluate time to follow-up in a cross-sectional cohort of African American and Hispanic women who obtained mammogram screening at a county facility. METHODS Time to follow-up was assessed in days after an abnormal mammogram to subsequent clinical care in a cross-sectional study of 74 women. RESULTS The median number of days until clinical follow-up after an abnormal mammogram for women in the study was 30 days (Range: 0-357 days). There was a statistically significant difference in the time-to-biopsy among women who had incomplete mammograms and women who had comorbid conditions. CONCLUSIONS This data indicates that county services provide clinical follow-up in compliance with recommended guidelines of 30 days. However, women with incomplete mammograms and comorbid conditions may be at a higher risk of experiencing delays in diagnosis and treatment.

Abstract
Triple Negative Breast Cancer (TNBC) is an aggressive, heterogeneous subtype of breast cancer, which is more frequently diagnosed in African American (AA) women than in European American (EA) women. The purpose of this study is to investigate the role of social determinants in racial disparities in TNBC. Data on Louisiana TNBC patients diagnosed in 2010–2012 were collected and geocoded to census tract of residence at diagnosis by the Louisiana Tumor Registry. Using multilevel statistical models, we analyzed the role of neighborhood concentrated disadvantage index (CDI), a robust measure of physical and social environment, in racial disparities in TNBC incidence, stage at diagnosis, and stage-specific survival for the study population. Controlling for age, we found that AA women had a 2.21 times the incidence of TNBC incidence compared to EA women. Interestingly, the incidence of TNBC was independent of neighborhood CDI and adjusting for neighborhood environment did not impact the observed racial disparity. AA women were more likely to be diagnosed at later stages and CDI was associated with more advanced stages of TNBC at diagnosis. CDI was also significantly associated with poorer stage-specific survival. Overall, our results suggest that neighborhood disadvantage contributes to racial disparities in stage at diagnosis and survival among TNBC patients, but not to disparities in incidence of the disease. Further research is needed to determine the mechanisms through which social determinants affect the promotion and progression of this disease and guide efforts to improve overall survival.

Predictors of breast cancer mortality among white and black women in large United States cities: an ecologic study. Cancer Causes Control 2019; 30:149-164. [PMID: 30656540 DOI: 10.1007/s10552-018-1125-x] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/04/2018] [Accepted: 12/31/2018] [Indexed: 12/20/2022]
Abstract
PURPOSE We employed a city-level ecologic analysis to assess predictors of race-specific (black and white) breast cancer mortality rates. METHODS We used data from the National Center for Health Statistics and the US Census Bureau to calculate 2010-2014 race-specific breast cancer mortality rates (BCMR) for 47 of the largest US cities. Data on potential city-level predictors (e.g., socioeconomic factors, health care resources) of race-specific BCMR were obtained from various publicly available datasets. We constructed race-specific multivariable negative binomial regression models to estimate rate ratios (RR) and 95% confidence intervals (CIs). RESULTS Predictors of the white BCMR included white/black differences in education (RR 0.95; CI 0.91-0.99), number of religious congregations (RR 0.87; CI 0.77-0.97), and number of Medicare primary care physicians (RR 1.15; CI 1.04-1.28). Predictors of the black rate included white/black differences in household income (RR 1.03; CI 1.01-1.05), number of mammography facilities (RR 1.07; CI 1.03-1.12), and mammogram use (RR 0.93; CI 0.89-0.97). CONCLUSIONS Our ecologic analysis found that predictors of breast cancer mortality differ for the black and white rate. The results of this analysis could help inform interventions at the local level.

Abstract
PURPOSE Prior research demonstrates racial disparities in breast cancer treatment. Disparities are commonly attributed to more advanced stage at presentation or aggressive tumor biology. We seek to evaluate if racial disparities persist in the treatment of stage 1 breast cancer patients who by definition are not delayed in presentation. METHODS We selected stage 1 breast cases in the National Cancer Data Base. Patients were divided into two cohorts based on race and included White and Black patients. We also performed a subgroup analysis of patients with private insurance for comparison to determine if private insurance diminished the racial disparities noted. We analyzed differences in time to treatments by race. RESULTS Our analysis included 546,351 patients of which 494,784 (90.6%) were White non-Hispanic and 51,567 (9.4%) were Black non-Hispanic. Black women had significantly longer times to first treatment (35.5 days vs 28.1 days), surgery (36.6 days vs 28.8 days), chemotherapy (88.1 days vs 75.4 days), radiation (131.3 days vs 99.1 days), and endocrine therapy (152.1 days vs 126.5 days) than White women. When patients with private insurance were analyzed the difference in time to surgery decreased by 1.2 days but racial differences remained statistically significant. CONCLUSIONS Despite selecting for early-stage breast cancer, racial disparities between White and Black women in time to all forms of breast cancer treatment persist. These disparities while likely not oncologically significant do suggest institutional barriers for obtaining care faced by women of color which may not be addressed with improving access to mammography alone.

Abstract
PURPOSE The goals of this study were to identify geographic and racial/ethnic variation in breast cancer mortality, and evaluate whether observed geographic differences are explained by county-level characteristics. METHODS We analyzed data on breast cancer deaths among women in 3,108 contiguous United States (US) counties from years 2000 through 2015. We applied novel geospatial methods and identified hot spot counties based on breast cancer mortality rates. We assessed differences in county-level characteristics between hot spot and other counties using Wilcoxon rank-sum test and Spearman correlation, and stratified all analysis by race/ethnicity. RESULTS Among all women, 80 of 3,108 (2.57%) contiguous US counties were deemed hot spots for breast cancer mortality with the majority located in the southern region of the US (72.50%, p value < 0.001). In race/ethnicity-specific analyses, 119 (3.83%) hot spot counties were identified for NH-Black women, with the majority being located in southern states (98.32%, p value < 0.001). Among Hispanic women, there were 83 (2.67%) hot spot counties and the majority was located in the southwest region of the US (southern = 61.45%, western = 33.73%, p value < 0.001). We did not observe definitive geographic patterns in breast cancer mortality for NH-White women. Hot spot counties were more likely to have residents with lower education, lower household income, higher unemployment rates, higher uninsured population, and higher proportion indicating cost as a barrier to medical care. CONCLUSIONS We observed geographic and racial/ethnic disparities in breast cancer mortality: NH-Black and Hispanic breast cancer deaths were more concentrated in southern, lower SES counties.

Abstract
INTRODUCTION Non-Hispanic black (NHB) women with breast cancer have poorer survival than non-Hispanic white (NHW) women. Although NHB women are more often diagnosed at later stages, it is less established whether racial disparities exist among women diagnosed with late-stage breast cancer, particularly when care is provided in the community setting. METHODS Treatment and survival were examined by race/ethnicity among women diagnosed in 2012 with stage IIIB-IV breast cancer using the National Cancer Institute's population-based Patterns of Care Study. Medical records were re-abstracted and treating physicians were contacted to verify therapy. Vital status was available through 2014. RESULTS A total of 533 women with stage IIIB-C and 625 with stage IV tumors were included; NHW women comprised about 70% of each group. Among women with stage IIIB-C disease, racial/ethnicity variations in systemic treatment were not observed but there was a borderline association indicating worse all-cause mortality among NHB women (hazard ratio 1.52; 95% confidence interval (CI) 0.96-2.41). In contrast, among women with stage IV disease, borderline associations indicating NHB women were more likely to receive chemotherapy (OR 1.44, 95% CI 0.90-2.30) and, among those with hormone receptor-positive tumors, less likely to receive endocrine therapy (OR 0.60, 95% CI 0.35-1.04). All-cause mortality did not vary by race/ethnicity for stage IV disease (hazard ratio 0.92; 95% CI 0.68-1.25). CONCLUSIONS More research is needed to identify additional factors associated with the potential survival disparities among women with stage IIIB-C disease and potential treatment disparities among women with stage IV disease.

[PMID: 29763753 DOI: 10.1016/j.canep.2018.05.001] [Citation(s) in RCA: 20] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/05/2018] [Revised: 04/30/2018] [Accepted: 05/03/2018] [Indexed: 01/23/2023]
Abstract
BACKGROUND Hospitalized cancer patients are nearly 10 times more likely to develop sepsis when compared to patients with no cancer history. We compared the risk of sepsis between cancer survivors and no cancer history participants, and examined whether race was an effect modifier. METHODS We performed a prospective analysis of data from the REasons for Geographic and Racial Differences in Stroke (REGARDS) cohort. We categorized participants as "cancer survivors" or "no cancer history" derived from self-reported responses of being diagnosed with any cancer, excluding non-melanoma skin cancer. We defined sepsis as hospitalization for a serious infection with ≥2 systemic inflammatory response syndrome criteria. We performed Cox proportional hazard models to examine the risk of sepsis after cancer (adjusted for sociodemographics, health behaviors, and comorbidities), and stratified by race. RESULTS Among 29,693 eligible participants, 2959 (9.97%) were cancer survivors, and 26,734 (90.03%) were no cancer history participants. Among 1393 sepsis events, the risk of sepsis was higher for cancer survivors (adjusted HR: 2.61, 95% CI: 2.29-2.98) when compared to no cancer history participants. Risk of sepsis after cancer survivorship was similar for Black and White participants (p value for race and cancer interaction = 0.63). CONCLUSION In this prospective cohort of community-dwelling adults we observed that cancer survivors had more than a 2.5-fold increased risk of sepsis. Public health efforts should attempt to mitigate sepsis risk by awareness and appropriate treatment (e.g., antibiotic administration) to cancer survivors with suspected infection regardless of the number of years since cancer remission.

Literature review of data-based models for identification of factors associated with racial disparities in breast cancer mortality. Health Syst (Basingstoke) 2018; 8:75-98. [PMID: 31275571 PMCID: PMC6598506 DOI: 10.1080/20476965.2018.1440925] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/01/2016] [Revised: 01/29/2018] [Accepted: 02/08/2018] [Indexed: 01/03/2023] Open
Abstract
In the United States, early detection methods have contributed to the reduction of overall breast cancer mortality but this pattern has not been observed uniformly across all racial groups. A vast body of research literature shows a set of health care, socio-economic, biological, physical, and behavioural factors influencing the mortality disparity. In this paper, we review the modelling frameworks, statistical tests, and databases used in understanding influential factors, and we discuss the factors documented in the modelling literature. Our findings suggest that disparities research relies on conventional modelling and statistical tools for quantitative analysis, and there exist opportunities to implement data-based modelling frameworks for (1) exploring mechanisms triggering disparities, (2) increasing the collection of behavioural data, and (3) monitoring factors associated with the mortality disparity across time.
