Abstract
The diagnostic workup following a positive prostate‐specific antigen test may lead to significant out‐of‐pocket costs for patients. Providers should incorporate costs into shared decision‐making with patients; in parallel, policymakers and payers must identify solutions to mitigate financial burdens that risk widening existing disparities in prostate cancer care.

A qualitative approach to understanding the drivers of unequal receipt of definitive therapy for Black men with prostate cancer in Massachusetts. Cancer 2024. [PMID: 38837334 DOI: 10.1002/cncr.35366] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/06/2023] [Revised: 03/29/2024] [Accepted: 04/12/2024] [Indexed: 06/07/2024]
Abstract
BACKGROUND Despite mandated insurance coverage since 2006 and robust health infrastructure in urban settings with high concentrations of minority patients, race-based disparities in prostate cancer (PCa) treatment persist in Massachusetts. In this qualitative study, the authors sought to identify factors driving inequities in PCa treatment in Massachusetts. METHODS Four hospitals offering PCa treatment in Massachusetts were selected using a case-mix approach. Purposive sampling was used to conduct semistructured interviews with hospital stakeholders. Additional interviews were conducted with representatives from grassroots organizations providing PCa education. Two study staff coded the interviews to identify major themes and recurrent patterns. RESULTS Of the 35 informants invited, 25 participated in the study. Although national disparities in PCa outcomes were readily discussed, one half of the informants were unaware that PCa disparities existed in Massachusetts. Informants and grassroots organization representatives acknowledged that patients with PCa are willing to face transportation barriers to receive treatment from trusted and accommodating institutions. Except for chief equity officers, most health care providers lacked knowledge on accessing or using metrics regarding racial disparities in cancer outcomes. Although community outreach was recognized as a potential strategy to reduce treatment disparities and engender trust, informants were often unable to provide a clear implementation plan. CONCLUSIONS This statewide qualitative study builds on existing quantitative data on the nature and extent of disparities. It highlights knowledge gaps in recognizing and addressing racial disparities in PCa treatment in Massachusetts. Improved provider awareness, the use of disparity metrics, and strategic community engagement may ensure equitable access to PCa treatment. PLAIN LANGUAGE SUMMARY Despite mandated insurance and urban health care access, racial disparities in prostate cancer treatment persist in Massachusetts. This qualitative study revealed that, although national disparities were acknowledged, awareness about local disparities are lacking. Stakeholders highlighted the importance of ancillary services, including translators, rideshares, and navigators, in the delivery of care. In addition, whereas hospital stakeholders were aware of collected equity outcomes, they were unsure whether and who is monitoring equity metrics. Furthermore, stakeholders agreed that community outreach showed promise in ensuring equitable access to prostate cancer treatment. Nevertheless, most interviewed stakeholders lacked clear implementation plans.

Abstract
BACKGROUND Prostate cancer (PCa), one of the most prevalent malignancies affecting men, significantly contributes to increased mortality rates worldwide. While the causative death is due to advanced metastatic disease, this occurrence disproportionately impacts men of African descent compared to men of European descent. In this review, we describe potential mechanisms underlying PCa metastases disparities and current treatments for metastatic disease among these populations, differences in treatment outcomes, and survival rates, in hopes of highlighting a need to address disparities in PCa metastases. METHODS We reviewed existing literature using databases such as PubMed, Google Scholar, and Science Direct using the following keywords: "prostate cancer metastases", "metastatic prostate cancer disparity", "metastatic prostate cancer diagnosis and treatment", "prostate cancer genetic differences and mechanisms", "genetic differences and prostate tumor microenvironment", and "men of African descent and access to clinical treatments". The inclusion criteria for literature usage were original research articles and review articles. RESULTS Studies indicate unique genetic signatures and molecular mechanisms such as Epithelial-Mesenchymal Transition (EMT), inflammation, and growth hormone signaling involved in metastatic PCa disparities. Clinical studies also demonstrate differences in treatment outcomes that are race-specific, for example, patients of African descent have a better response to enzalutamide and immunotherapy yet have less access to these drugs as compared to patients of European descent. CONCLUSIONS Growing evidence suggests a connection between a patient's genetic profile, the prostate tumor microenvironment, and social determinants of health that contribute to the aggressiveness of metastatic disease and treatment outcomes. With several potential pathways highlighted, the limitations in current diagnostic and therapeutic applications that target disparity in PCa metastases warrant rigorous research attention.

Neighborhood Deprivation, Race and Ethnicity, and Prostate Cancer Outcomes Across California Health Care Systems. JAMA Netw Open 2024; 7:e242852. [PMID: 38502125 PMCID: PMC10951732 DOI: 10.1001/jamanetworkopen.2024.2852] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/10/2023] [Accepted: 01/25/2024] [Indexed: 03/20/2024] Open
Abstract
Importance Non-Hispanic Black (hereafter, Black) individuals experience worse prostate cancer outcomes due to socioeconomic and racial inequities of access to care. Few studies have empirically evaluated these disparities across different health care systems. Objective To describe the racial and ethnic and neighborhood socioeconomic status (nSES) disparities among residents of the same communities who receive prostate cancer care in the US Department of Veterans Affairs (VA) health care system vs other settings. Design, Setting, and Participants This cohort study obtained data from the VA Central Cancer Registry for veterans with prostate cancer who received care within the VA Greater Los Angeles Healthcare System (VA cohort) and from the California Cancer Registry (CCR) for nonveterans who received care outside the VA setting (CCR cohort). The cohorts consisted of all males with incident prostate cancer who were living within the same US Census tracts. These individuals received care between 2000 and 2018 and were followed up until death from any cause or censoring on December 31, 2018. Data analyses were conducted between September 2022 and December 2023. Exposures Health care setting, self-identified race and ethnicity (SIRE), and nSES. Main Outcomes and Measures The primary outcome was all-cause mortality (ACM). Cox proportional hazards regression models were used to estimate hazard ratios for associations of SIRE and nSES with prostate cancer outcomes in the VA and CCR cohorts. Results Included in the analysis were 49 461 males with prostate cancer. Of these, 1881 males were in the VA cohort (mean [SD] age, 65.3 [7.7] years; 833 Black individuals [44.3%], 694 non-Hispanic White [hereafter, White] individuals [36.9%], and 354 individuals [18.8%] of other or unknown race). A total of 47 580 individuals were in the CCR cohort (mean [SD] age, 67.0 [9.6] years; 8183 Black individuals [17.2%], 26 206 White individuals [55.1%], and 13 191 individuals [27.8%] of other or unknown race). In the VA cohort, there were no racial disparities observed for metastasis, ACM, or prostate cancer-specific mortality (PCSM). However, in the CCR cohort, the racial disparities were observed for metastasis (adjusted odds ratio [AOR], 1.36; 95% CI, 1.22-1.52), ACM (adjusted hazard ratio [AHR], 1.13; 95% CI, 1.04-1.24), and PCSM (AHR, 1.15; 95% CI, 1.05-1.25). Heterogeneity was observed for the racial disparity in ACM in the VA vs CCR cohorts (AHR, 0.90 [95% CI, 0.76-1.06] vs 1.13 [95% CI, 1.04-1.24]; P = .01). No evidence of nSES disparities was observed for any prostate cancer outcomes in the VA cohort. However, in the CCR cohort, heterogeneity was observed for nSES disparities with ACM (AHR, 0.82; 95% CI, 0.80-0.84; P = .002) and PCSM (AHR, 0.86; 95% CI, 0.82-0.89; P = .007). Conclusions and Relevance Results of this study suggest that racial and nSES disparities were wider among patients seeking care outside of the VA health care system. Health systems-related interventions that address access barriers may mitigate racial and socioeconomic disparities in prostate cancer.

Abstract
PURPOSE To identify whether there was a disparity in the utilization of immunotherapy in the treatment of black patients with metastatic castration resistant prostate cancer (mCRPC). METHODS Using the National Cancer Database, we identified patients between 2010- 2015 with likely minimally/asymptomatic mCRPC. We analyzed annual trends for chemotherapy and immunotherapy use and compared utilization by demographic and clinical features. Multivariable analysis was performed to determine predictors of receiving immunotherapy vs chemotherapy. RESULTS We identified 1301 patients with likely mCRPC. The majority were non Hispanic White (NHW - 63 %) and 23 % were non-Hispanic Black (NHB). Overall, there was increased utilization of immunotherapy in mCRPC from 2010 onwards, with the peak occurring in 2014 (4.6 %). Chemotherapy use increased significantly, peaking in 2014 to 26.1 %. However, the increased utilization of immunotherapy in the mCRPC was mainly seen in White patients: from 50 % to 74.2 % of the cohort. Conversely, there was a decrease in utilization of immunotherapy among Black mCPRC patients: from 50 % to 25.8 %. On multivariable analysis, there was no statistically significant difference between treatment types by race. CONCLUSION FDA approval of Sipuleucel-T for mCRPC led to increased utilization of immunotherapy shortly thereafter, but this was mainly noted in white patients. Black patients comparatively did not exhibit increased utilization of this novel agent after 2010. Further studies are necessary to help understand barriers to access to new treatment in mCRPC and eliminate the burden of disease in minority populations."

Abstract
Financial toxicity is a growing problem in the delivery of cancer care and contributes to inequities in outcomes across the cancer care continuum. Racial/ethnic inequities in prostate cancer, the most common cancer diagnosed in men, are well described, and threaten to widen in the era of precision oncology given the numerous structural barriers to accessing novel diagnostic studies and treatments, particularly for Black men. Gaps in insurance coverage and cost sharing are 2 such structural barriers that can perpetuate inequities in screening, diagnostic workup, guideline-concordant treatment, symptom management, survivorship, and access to clinical trials. Mitigating these barriers will be key to achieving equity in prostate cancer care, and will require a multi-pronged approach from policymakers, health systems, and individual providers. This narrative review will describe the current state of financial toxicity in prostate cancer care and its role in perpetuating racial inequities in the era of precision oncology.

Abstract
PURPOSE Black men have a higher risk of prostate cancer diagnosis and mortality but are less likely to receive definitive treatment. The impact of structural aspects on treatment is unknown but may lead to actionable insights to mitigate disparities. We sought to examine the associations between urology practice organization and racial composition and treatment patterns for Medicare beneficiaries with incident prostate cancer. METHODS Using a 20% sample of national Medicare data, we identified beneficiaries diagnosed with prostate cancer between January 2010 and December 2015 and followed them through 2016. We linked urologists to their practices with tax identification numbers. We then linked patients to practices on the basis of their primary urologist. We grouped practices into quartiles on the basis of their proportion of Black patients. We used multilevel mixed-effects models to identify treatment associations. RESULTS We identified 54,443 patients with incident prostate cancer associated with 4,194 practices. Most patients were White (87%), and 9% were Black. We found wide variation in racial practice composition and practice segregation. Patients in practices with the highest proportion of Black patients had the lowest socioeconomic status (43.1%), highest comorbidity (9.9% with comorbidity score ≥ 3), and earlier age at prostate cancer diagnosis (33.5% age 66-69 years; P < .01). Black patients had lower odds of definitive therapy (adjusted odds ratio, 0.87; 95% CI, 0.81 to 0.93) and underwent less treatment than White patients in every practice context. Black patients in practices with higher proportions of Black patients had higher treatment rates than Black patients in practices with lower proportions. Black patients had lower predicted probability of treatment (66%) than White patients (69%; P < .05). CONCLUSION Despite Medicare coverage, we found less definitive treatment among Black beneficiaries consistent with ongoing prostate cancer treatment disparities. Our findings are reflective of the adverse effects of practice segregation and structural racism, highlighting the need for multilevel interventions.

Abstract
BACKGROUND While the 5-year survival rate for local and regional prostate cancer is nearly 100%, it decreases dramatically for advanced tumours. Accessibility to health care is an important factor for cancer prognosis. The U.S. Military Health System (MHS) provides universal health care to its beneficiaries, reducing financial barriers to medical care. However, whether the universal care translates into improved survival among patients with advanced prostate cancer in the MHS is unknown. In this study, we compared the MHS and the U.S. general population in survival of patients with advanced prostate cancer (stages III and IV). METHODS The MHS patients (N = 5379) were identified from the Department of Defense's (DoD) Automated Central Tumor Registry (ACTUR). Patients in the U.S. general population (N = 21,516) were identified from the Surveillance, Epidemiology, and End Results (SEER) programme. The two populations were matched on age, race, and diagnosis year. RESULTS The ACTUR patients exhibited longer 5-year survival than the matched SEER patients (HR = 0.74, 95% CI = 0.67-0.83), after adjustment for the potential confounders. The improved survival was observed for ages 50 years or older, both White patients and Black patients, all tumour stages and grades. This was also demonstrated despite the receipt of surgery or radiation treatment. CONCLUSIONS MHS beneficiaries with advanced prostate cancer had longer survival than their counterparts in the U.S. general population.

Abstract
Obamacare is the colloquial name given to the Affordable Care Act (ACA) signed into law by President Obama in the USA, which ultimately aims to provide universal access to health care services for US citizens. The aim of this paper is to provide an overview of the political-legal, economic, social, management (or administrative), and medical (or health) repercussions of this law, using a bibliometric methodology as a basis. In addition, the main contributors to research on ACA issues have been identified in terms of authors, organizations, journals, and countries. The downward trend in scientific production on this law has been noted, and it has been concluded that a balance has not yet been reached between the coexistence of private and public health care that guarantees broad social coverage without economic or other types of barriers. The law requires political consensus to be implemented in a definitive and global manner for the whole of the United States.

Abstract
BACKGROUND Previous research exploring the role of race on prostate cancer (PCa) outcomes has demonstrated greater rates of disease progression and poorer overall survival for African American (AA) compared to Caucasian American (CA) men. The current study examines self-reported race as a predictor of long-term PCa outcomes in patients with low and favorable-intermediate risk disease treated with external beam radiation therapy (EBRT). METHODS This retrospective cohort study examined patients who were consented to enrollment in the Center for Prostate Disease Research Multicenter National Database between January 01, 1990 and December 31, 2017. Men self-reporting as AA or CA who underwent EBRT for newly diagnosed National Comprehensive Cancer Network-defined low or favorable-intermediate risk PCa were included. Dependent study outcomes included: biochemical recurrence-free survival, (ii) distant metastasis-free survival, and (iii) overall survival. Each outcome was modeled as a time-to-event endpoint using race-stratified Kaplan-Meier estimation curves and multivariable Cox proportional hazards analysis. RESULTS Of 840 men included in this study, 268 (32%) were AA and 572 (68%) were CA. The frequency of biochemical recurrence, distant metastasis, and deaths from any cause was 151 (18.7%), 29 (3.5%), and 333 (39.6%), respectively. AA men had a significantly younger median age at time of EBRT and slightly higher biopsy Gleason scores. Multivariable Cox proportional hazards analyses demonstrated no racial differences in any of the study endpoints. CONCLUSIONS These findings reveal no racial disparity in PCa outcomes for AA compared to CA men, in a long-standing, longitudinal cohort of patients with comparable access to cancer care.

Access and Representation: A Narrative Review of the Disparities in Access to Clinical Trials and Precision Oncology in Black men with Prostate Cancer. Urology 2022; 163:90-98. [PMID: 34582887 DOI: 10.1016/j.urology.2021.09.004] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/04/2021] [Revised: 08/20/2021] [Accepted: 09/14/2021] [Indexed: 11/24/2022]
Abstract
OBJECTIVE To provide commentary on the disparities in access to clinical trials and precision oncology specific to Black men with Prostate Cancer (PCa) in the United States and lend a general framework to aid in closing these gaps. MATERIALS AND METHODS The ideas, commentaries and data presented in this narrative review were synthesized by utilizing qualitative and quantitative studies, reviews, and randomized control trials performed between 2010 and 2021. We searched PubMed using the key words "Medicaid", "Medicare", "clinical trials", "African Americans", "Black", "underrepresentation", "access", "Prostate Cancer", "minority recruitment", "racial disparities", "disparity", "genomics", "biomarkers", "diagnostic" "prognostic", "validation", "precision medicine", and "precision oncology" to identify important themes, trends and data described in the current review. Keywords were used alone and combination with both "AND" and "OR" terms. RESULTS Black men with prostate cancer (PCa) in the United States have earlier onset of disease, present with more advanced stages, and worse prostate cancer-specific survival than their White counterparts. Potential causative factors vary from disparities in health care access to differences in tumor immunobiology and genomics along with disparate screening rates, management patterns and underrepresentation in clinical and translational research such as clinical trials and precision oncology. CONCLUSION To avoid increasing the racial disparity in PCa outcomes for Black men, we must increase inclusion of Black men into precision oncology and clinical trials, using multilevel change. Underrepresentation in clinical and translational research may potentiate poorly validated risk calculators and biomarkers, leading to poor treatment decisions in high-risk populations. Relevant actions include funding to include minority-serving institutions as recruitment sites, and inclusion of evidence based recruitment methods in funded research to increase Black representation in clinical trials and translational research.

Abstract
Compared to Caucasians (CAs), African Americans (AAs) have a higher rate of incidence and mortality in prostate cancer and are prone to be diagnosed at later stages. To understand this racial disparity, molecular features of different types, including gene expression, DNA methylation and other genomic alterations, have been compared between tumor samples from the two races, but led to different disparity associated genes (DAGs). In this study, we applied a network-based algorithm to integrate a comprehensive set of genomic datasets and identified 130 core DAGs. Out of these genes, 78 were not identified by any individual dataset but prioritized and selected through network propagation. We found DAGs were highly enriched in several critical prostate cancer-related signaling transduction and cell cycle pathways and were more likely to be associated with patient prognosis in prostate cancer. Furthermore, DAGs were over-represented in prostate cancer risk genes identified from previous genome wide association studies. We also found DAGs were enriched in kinase and transcription factor encoding genes. Interestingly, for many of these prioritized kinases their association with racial disparity did not manifest from the original genomic/transcriptomic data but was reflected by their differential phosphorylation levels between AA and CA prostate tumor samples. Similarly, the disparity relevance of some transcription factors was not reflected at the mRNA or protein expression level, but at the activity level as demonstrated by their differential ability in regulating target gene expression. Our integrative analysis provided new candidate targets for improving prostate cancer treatment and addressing the racial disparity problem.

Abstract
OBJECTIVE The aim of this study was to investigate prenatal factors associated with insulin prescription as a first-line pharmacotherapy for gestational diabetes mellitus (GDM; compared with oral antidiabetic medication) after failed medical nutrition therapy. STUDY DESIGN This is a retrospective cohort study of 437 women with a singleton pregnancy and diagnosis of A2GDM (GDM requiring pharmacotherapy), delivering in a university hospital between 2015 and 2019. Maternal sociodemographic and clinical characteristics, as well as GDM-related factors, including provider type that manages GDM, were compared between women who received insulin versus oral antidiabetic medication (metformin or glyburide) as the first-line pharmacotherapy using univariable and multivariable analyses. RESULTS In univariable analysis, maternal age, race and ethnicity, insurance, chronic hypertension, gestational age at GDM diagnosis, glucose level after 50-g glucose loading test, and provider type were associated with insulin prescription. In multivariable analysis, after adjusting for sociodemographic and clinical maternal factors, GDM characteristics and provider type, Hispanic ethnicity (0.26, 95% confidence interval [CI]: 0.09-0.73), and lack of insurance (0.34, 95% CI: 0.13-0.89) remained associated with lower odds of insulin prescription, whereas endocrinology management of GDM (compared with obstetrics and gynecology [OBGYN]) (8.07, 95% CI: 3.27-19.90) remained associated with higher odds of insulin prescription. CONCLUSION Women of Hispanic ethnicity and women with no insurance were less likely to receive insulin and more likely to receive oral antidiabetic medication for GDM pharmacotherapy, while management by endocrinology was associated with higher odds of insulin prescription.This finding deserves more investigation to understand if differences are due to patient choice or a health disparity in the choice of pharmacologic agent for A2GDM. KEY POINTS · Insulin is recommended as a first-line pharmacotherapy for gestational diabetes.. · Women of Hispanic ethnicity were less likely to receive insulin as first line.. · Lack of insurance was also associated with lower odds of insulin prescription..

Evaluating Prostate-Specific Antigen Screening for Young African American Men With Cancer. J Natl Cancer Inst 2021; 114:592-599. [PMID: 34893859 PMCID: PMC9002290 DOI: 10.1093/jnci/djab221] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/20/2021] [Revised: 08/02/2021] [Accepted: 11/30/2021] [Indexed: 11/14/2022] Open
Abstract
BACKGROUND Despite higher risks associated with prostate cancer, young African American men are poorly represented in prostate-specific antigen (PSA) trials, which limits proper evidence-based guidance. We evaluated the impact of PSA screening, alongside primary care provider utilization, on prostate cancer outcomes for these patients. METHODS We identified African American men aged 40-55 years, diagnosed with prostate cancer between 2004 and 2017 within the Veterans Health Administration. Inverse probability of treatment-weighted propensity scores were used in multivariable models to assess PSA screening on PSA levels higher than 20, Gleason score of 8 or higher, and metastatic disease at diagnosis. Lead-time adjusted Fine-Gray regression evaluated PSA screening on prostate cancer-specific mortality (PCSM), with noncancer death as competing events. All statistical tests were 2-sided. RESULTS The cohort included 4726 patients. Mean age was 51.8 years, with 84-month median follow-up. There were 1057 (22.4%) with no PSA screening prior to diagnosis. Compared with no screening, PSA screening was associated with statistically significantly reduced odds of PSA levels higher than 20 (odds ratio [OR] = 0.56, 95% confidence interval [CI] = 0.49 to 0.63; P < .001), Gleason score of 8 or higher (OR = 0.78, 95% CI = 0.69 to 0.88; P < .001), and metastatic disease at diagnosis (OR = 0.50, 95% CI = 0.39 to 0.64; P < .001), and decreased PCSM (subdistribution hazard ratio = 0.52, 95% CI = 0.36 to 0.76; P < .001). Primary care provider visits displayed similar effects. CONCLUSIONS Among young African American men diagnosed with prostate cancer, PSA screening was associated with statistically significantly lower risk of PSA levels higher than 20, Gleason score of 8 or higher, and metastatic disease at diagnosis and statistically significantly reduced risk of PCSM. However, the retrospective design limits precise estimation of screening effects. Prospective studies are needed to validate these findings.

Abstract
The compounding effects of occupying two or more social identities, such as being "Black" and "female" have been described in intersectionality theory. Intersectionality, a term coined by legal scholar and activist Kimberlé Crenshaw, is a framework to consider race and other social identities as overlapping, dynamic, and interdependent identities. Since its inception, intersectionality has made significant in-roads to inform the conceptualization and empirical investigations of race, gender, and other social identities in sociology, critical race theory, anthropology, feminist theory, and other disciplines. However, to date, cost effectiveness research has not systematically examined race intersecting with other social identities in the valuation of medicines using social theory, such as intersectionality. Consequently, cost effectiveness analysis, which is a method to study the value of medicines in diverse populations, has not been subject to sufficient examination through an intersectionality framework. In the US context, the racial injustices experienced and documented within diverse communities highlight that health outcomes cannot be examined in a vacuum; overlapping social identities such as race and class in relation to context have real effects on health behaviors, measured preferences, and economic costs. Failure to examine the effects of overlapping social identities on heterogeneity in benefits and costs can result in inadequate information for decision makers to evaluate the value of treatments. Without consideration of the overlapping social identities in diverse populations, there is a risk that cost effectiveness analysis results will not accurately reflect the value of treatments in socially disadvantaged populations. In this Current Opinion, we provide an outline for conducting socially conscious cost effectiveness analyses, using intersectionality as one example.

Abstract
BACKGROUND Currently, little is known about the effect of the Patient Protection and Affordable Care Act's Medicaid expansion on care delivery and outcomes in cervical cancer. AIM We evaluated whether Medicaid expansion was associated with changes in insurance status, stage at diagnosis, timely treatment, and survival outcomes in cervical cancer. METHODS AND RESULTS Using the National Cancer Database, we performed a difference-in-differences (DID) cross-sectional analysis to compare insurance status, stage at diagnosis, timely treatment, and survival outcomes among cervical cancer patients residing in Medicaid expansion and nonexpansion states before (2011-2013) and after (2014-2015) Medicaid expansion. January 1, 2014 was used as the timepoint for Medicaid expansion. The primary outcomes of interest were insurance status, stage at diagnosis, treatment within 30 and 90 days of diagnosis, and overall survival. Fifteen thousand two hundred sixty-five patients (median age 50) were included: 42% from Medicaid expansion and 58% from nonexpansion states. Medicaid expansion was significantly associated with increased Medicaid coverage (adjusted DID = 11.0%, 95%CI = 8.2, 13.8, p < .01) and decreased rates of uninsured (adjusted DID = -3.0%, 95%CI = -5.2, -0.8, p < .01) among patients in expansion states compared with non-expansion states. However, Medicaid expansion was not associated with any significant changes in cancer stage at diagnosis or timely treatment. There was no significant change in survival from the pre- to post-expansion period in either expansion or nonexpansion states, and no significant differences between the two (DID-HR = 0.95, 95%CI = 0.83, 1.09, p = .48). CONCLUSION Although Medicaid expansion was associated with an increase in Medicaid coverage and decrease in uninsured among patients with cervical cancer, the effects of increased coverage on diagnosis and treatment outcomes may have yet to unfold. Future studies, including longer follow-up are necessary to understand the effects of Medicaid expansion.

Abstract
The relationship of social determinants of health, Appalachian residence, and prostate cancer treatment delay among Tennessee adults is relatively unknown. We used multivariate logistic regression on 2005–2015 Tennessee Cancer Registry data of adults aged ≥18 diagnosed with prostate cancer. The outcome of treatment delay was more than 90 days without surgical or nonsurgical intervention from date of diagnosis. Social determinants in the population-based registry were race (White, Black, Other) and marital status (single, married, divorced/separated, widow/widower). Tennessee residence was classified as Appalachian versus non-Appalachian (urban/rural). Covariates include age at diagnosis (18–54, 54–69, ≥70), health insurance type (none, public, private), derived staging of cancer (localized, regional, distant), and treatment type (non-surgical/surgical). We found that Black and divorced/separated patients had 32% (95% confidence interval [CI]: 1.22–1.42) and 15% (95% CI: 1.01–1.31) increased odds to delay prostate cancer treatment. Patients were at decreased odds of treatment delay when living in an Appalachian county, both urban (odds ratio [OR] = 0.89, 95% CI: 0.82–0.95) and rural (OR = 0.83, 95% CI: 0.78–0.89), diagnosed at ≥70 (OR = 0.59, 95% CI: 0.53–0.66), and received surgical intervention (OR = 0.72, 95% CI: 0.68–0.76). Our study was among the first to comprehensively examine prostate cancer treatment delay in Tennessee, and while we do not make clinical recommendations, there is a critical need to further explore the unique factors that may propagate disparities. Prostate cancer treatment delay in Black patients may be indicative of ongoing health and access disparities in Tennessee, which may further affect quality of life and survivorship among this racial group. Divorced/separated patients may need tailored interventions to improve social support.

Abstract
PURPOSE We assessed sociodemographic factors associated with and survival implications of refusal of potentially survival-prolonging locoregional treatment (LT, including radiotherapy and surgery) despite provider recommendation among men with localized prostate adenocarcinoma. METHODS The National Cancer Database (2004-2015) identified men with TxN0M0 prostate cancer who either received or refused LT despite provider recommendation. Multivariable logistic regression defined adjusted odds ratios (AORs) with 95% CI of refusing LT, with sociodemographic and clinical covariates. Models were stratified by low-risk and intermediate- or high-risk (IR or HR) disease, with a separate interaction analysis between race and risk group. Multivariable Cox proportional hazard ratios compared overall survival (OS) among men who received versus refused LT. RESULTS Of 887,839 men (median age 64 years, median follow-up 6.14 years), 2,487 (0.28%) refused LT. Among men with IR or HR disease (n = 651,345), Black and Asian patients were more likely to refuse LT than White patients (0.35% v 0.29% v 0.17%; Black v White AOR, 1.75; 95% CI, 1.52 to 2.01; P < .001; Asian v White AOR, 1.47; 95% CI, 1.05 to 2.06; P = .027, race * risk group interaction P < .001). Later year of diagnosis, community facility type, noninsurance or Medicaid, and older age were also associated with increased odds of LT refusal, overall and when stratifying by risk group. For men with IR or HR disease, LT refusal was associated with worse OS (5-year OS 80.1% v 91.5%, HR, 1.65, P < .001). CONCLUSION LT refusal has increased over time; racial disparities were greater in higher-risk disease. Refusal despite provider recommendation highlights populations that may benefit from efforts to assess and reduce barriers to care.

Prostate Cancer Racial Disparities: A Systematic Review by the Prostate Cancer Foundation Panel. Eur Urol Oncol 2021; 5:18-29. [PMID: 34446369 DOI: 10.1016/j.euo.2021.07.006] [Citation(s) in RCA: 38] [Impact Index Per Article: 12.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/08/2021] [Revised: 07/14/2021] [Accepted: 07/27/2021] [Indexed: 12/21/2022]
Abstract
CONTEXT Prostate cancer (PCa) is a complex disease that disproportionately impacts Black men in the USA. The structural factors that drive heterogeneous outcomes for patients of differing backgrounds are probably the same ones that result in population-level disparities. The relative contribution of drivers along the PCa disease continuum is an active area of investigation and debate. OBJECTIVE To critically synthesize the available evidence on PCa disparities from a population-level perspective in comparison to data from "equal access and equal care settings" and to provide a consensus summary of the state of PCa disparities. EVIDENCE ACQUISITION A plenary panel on PCa disparities presented at the Prostate Cancer Foundation meeting on October 24, 2019 and ensuing discussions are reported here. We used a systematic literature review approach and the Preferred Reporting Items for Systematic Reviews and Meta-analyses to select the most relevant publications. A total of 3333 publications between 2011 and 2021 were retrieved, of which 52 were included in the review; an additional 13 articles on screening guidelines, seminal clinical trials, and statistical methodology were used in the evidence synthesis. EVIDENCE SYNTHESIS Race disparities in PCa are a result of a complex interaction between socioeconomic factors impacting access to care and ancestral/genetic factors that may influence tumor biology. Black men in the USA continue to have a nearly 1.8 times higher population-level mortality rate than White men. Failure to account for the race-specific incidence burden would continue to lead to residual disparity even after achieving relatively similar outcomes after primary treatment, resulting in a higher long-term mortality burden. Selection bias remains possible in PCa studies, which often rely on highly specific cohorts of Black men with higher use of health care resources that may not represent the average Black patient in the USA. Novel methods including mediation analysis and genetic ancestry rather than self-identified race can optimize analytical models investigating racial disparities and may lead to a better understanding of PCa genomic diversity and behavior. CONCLUSIONS Our findings emphasize the importance of racially diverse studies, including precision -omics, prevention, and targeted therapy initiatives, to elucidate mechanisms underlying racial differences in outcomes and response to therapy. We propose novel approaches for studying and addressing PCa disparities. Contemporary methods, particularly in the domain of mediation analysis, can promote scientific rigor in understanding these disparities. PATIENT SUMMARY Inaccurate data interpretation or lack of data altogether for Black men can impact policy and ultimately affect millions of individuals of African origin worldwide. Our review identifies a need to develop and prioritize a strategy for including Black and other men with prostate cancer in intervention studies and randomized clinical trials to halt the widening prostate cancer disparities.

Abstract
Prostate Specific Antigen (PSA) level in the serum is one of the most widely used markers in monitoring prostate cancer (PCa) progression, treatment response, and disease relapse. Although significant efforts have been taken to analyze various socioeconomic and cultural factors that contribute to the racial disparities in PCa, limited research has been performed to quantitatively understand how and to what extent molecular alterations may impact differential PSA levels present at varied tumor status between African-American and European-American men. Moreover, missing values among patients add another layer of difficulty in precisely inferring their outcomes. In light of these issues, we propose a data-driven, deep learning-based imputation and inference framework (DIIF). DIIF seamlessly encapsulates two modules: an imputation module driven by a regularized deep autoencoder for imputing critical missing information and an inference module in which two deep variational autoencoders are coupled with a graphical inference model to quantify the personalized and race-specific causal effects. Large-scale empirical studies on the independent sub-cohorts of The Cancer Genome Atlas (TCGA) PCa patients demonstrate the effectiveness of DIIF. We further found that somatic mutations in TP53, ATM, PTEN, FOXA1, and PIK3CA are statistically significant genomic factors that may explain the racial disparities in different PCa features characterized by PSA.

Racial differences in the treatment and outcomes for prostate cancer in Massachusetts. Cancer 2021; 127:2714-2723. [PMID: 33999405 DOI: 10.1002/cncr.33564] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/15/2020] [Revised: 03/03/2021] [Accepted: 03/05/2021] [Indexed: 12/29/2022]
Abstract
BACKGROUND Massachusetts is a northeastern state with universally mandated health insurance since 2006. Although Black men have generally worse prostate cancer outcomes, emerging data suggest that they may experience equivalent outcomes within a fully insured system. In this setting, the authors analyzed treatments and outcomes of non-Hispanic White and Black men in Massachusetts. METHODS White and Black men who were 20 years old or older and had been diagnosed with localized intermediate- or high-risk nonmetastatic prostate cancer in 2004-2015 were identified in the Massachusetts Cancer Registry. Adjusted logistic regression models were used to assess predictors of definitive therapy. Adjusted and unadjusted survival models compared cancer-specific mortality. Interaction terms were then used to assess whether the effect of race varied between counties. RESULTS A total of 20,856 men were identified. Of these, 19,287 (92.5%) were White. There were significant county-level differences in the odds of receiving definitive therapy and survival. Survival was worse for those with high-risk cancer (adjusted hazard ratio [HR], 1.50; 95% CI, 1.4-1.60) and those with public insurance (adjusted HR for Medicaid, 1.69; 95% CI, 1.38-2.07; adjusted HR for Medicare, 1.2; 95% CI, 1.14-1.35). Black men were less likely to receive definitive therapy (adjusted odds ratio, 0.78; 95% CI, 0.74-0.83) but had a 17% lower cancer-specific mortality (adjusted HR, 0.83; 95% CI, 0.7-0.99). CONCLUSIONS Despite lower odds of definitive treatment, Black men experience decreased cancer-specific mortality in comparison with White men in Massachusetts. These data support the growing body of research showing that Black men may achieve outcomes equivalent to or even better than those of White men within the context of a well-insured population. LAY SUMMARY There is a growing body of evidence showing that the excess risk of death among Black men with prostate cancer may be caused by disparities in access to care, with few or no disparities seen in universally insured health systems such as the Veterans Affairs and US Military Health System. Therefore, the authors sought to assess racial disparities in prostate cancer in Massachusetts, which was the earliest US state to mandate universal insurance coverage (in 2006). Despite lower odds of definitive treatment, Black men with prostate cancer experience reduced cancer-specific mortality in comparison with White men in Massachusetts. These data support the growing body of research showing that Black men may achieve outcomes equivalent to or even better than those of White men within the context of a well-insured population.

Abstract
BACKGROUND The aim of this study was to describe pathologic and short-term oncologic outcomes among Black and White men with grade group 4 or 5 prostate cancer managed primarily by radical prostatectomy. METHODS This was a multi-institutional, observational study (2005-2015) evaluating radical prostatectomy outcomes by self-identified race. Descriptive analysis was performed via nonparametric statistical testing to compare baseline clinicopathologic data. Univariable and multivariable time-to-event analyses were performed to assess biochemical recurrence (BCR), metastasis, cancer-specific mortality (CSM), and overall survival between Black and White men. RESULTS In total, 1662 men were identified with grade group 4 or 5 prostate cancer initially managed by radical prostatectomy. Black men represented 11.3% of the cohort (n = 188). Black men were younger, demonstrated a longer time from diagnosis to surgery, and were at a lower clinical stage (all P < .05). Black men had lower rates of pT3/4 disease (49.5% vs 63.5%; P < .05) but higher rates of positive surgical margins (31.6% vs 26.5%; P = .14) on pathologic evaluation. There was no difference in BCR, CSM, or overall survival over a median follow-up of 40.7 months. Black men had a lower 5-year cumulative incidence of metastasis-free survival (93.6%; 95% confidence interval [CI], 86.5%-97.0%) in comparison with White men (85.8%; 95% CI, 83.1%-88.0%), which did not persist in an age-adjusted analysis. CONCLUSIONS Black and White men with high-grade prostate cancer at diagnosis demonstrated similar oncologic outcomes when they were managed by primary radical prostatectomy. Our findings suggest that racial disparities in prostate cancer mortality are not related to differences in the efficacy of extirpative therapy.

Abstract
PURPOSE Cancer disparities persist among medically underserved populations despite widespread efforts to address them. We describe the development of a framework for addressing cancer care disparities across the cancer care continuum (CCC), guided by the CCC domains established by the Institute of Medicine/National Academies of Sciences, Engineering, and Medicine (IOM/NAS). MATERIALS AND METHODS An environmental scan was conducted to identify strategies and associated experts who are providing or have successfully provided community- and/or patient-centric IOM/NAS-defined domain standards to our target populations. A multistakeholder expert roundtable working group was convened for framework development. A premeeting survey informed agenda development, documented expert practices for target populations, and identified priority areas for meeting focus. RESULTS The environmental scan identified 84 unique experts across 8 stakeholder groups and 44 patient organizations; 50 were invited to the roundtable and 33 participated. They broadly represented disease sites, geography, and experience with target populations and all CCC domains. The premeeting survey (16 responses) identified coordination of care or patient navigation (66.7%), community engagement (60.0%), and healthcare system changes (53.3%) as priority focus areas. The experts identified access and treatment barriers or gaps within and between CCC domains, specified key notable practices to address these, and developed an actionable framework and recommendations for each priority focus area. CONCLUSION The framework and recommendations are intended to guide researchers, healthcare leaders, advocates, community- and patient-focused service organizations, and policy leaders to address and promote health equity in cancer care access and treatment outcomes.

Abstract
Importance Although tissue-based genomic tests can aid in treatment decision-making for patients with prostate cancer, little is known about their clinical adoption. Objective To evaluate regional adoption of genomic testing for prostate cancer and understand common trajectories of uptake shared by regions. Design, Setting, and Participants This dynamic cohort study of patients diagnosed with prostate cancer used administrative claims from Blue Cross Blue Shield Axis, the largest source of commercial health insurance in the US, to characterize temporal trends in the use of commercial, tissue-based genomic testing and calculate the proportion of tested patients at the hospital referral region (HRR) level. Eligible patients from July 1, 2012, through June 30, 2018, were those aged 40 to 89 years with prostate cancer diagnosed from July 1, 2012, through June 30, 2018. Main Outcomes and Measures Group-based trajectory modeling was used to classify regions according to discrete trajectories of adoption of commercial, tissue-based genomic testing for prostate cancer. Across regions with distinct trajectories, HRR-level sociodemographic and health care contextual characteristics were compared, using data previously calculated among Medicare beneficiaries. Results A total of 92 418 men with prostate cancer who met inclusion criteria were identified; the median (interquartile range) age at diagnosis was 60 (56-63) years. Overall, the proportion of patients who received genomic testing increased from 0.8% in July 2012 to June 2013 to 11.3% in July 2017 to June 2018. Trajectory modeling identified 5 distinct regional trajectories of genomic testing adoption. Although less than 1% of patients in each group were tested at baseline, group 1 (lowest adoption) increased to 4.0%. Groups 2 (7.8%), 3 (14.6%), and 4 (17.3%) experienced more modest growth, while in group 5 (highest adoption), use increased to 33.8% of patients tested from June 2017 to July 2018. Compared with regions that more slowly adopted testing, HRRs with the highest rate of adoption (group 5) had higher HRR-level education measures (percentage [SD] with college education: group 1, 25.6% [4.8%]; vs group 2, 27.5% [7.3%]; vs group 3, 30.3% [9.1%]; vs group 4, 29.8% [8.2%]; vs group 5, 30.4% [11.4%]; P for trend = .03), median (SD) household income (group 1, $50 412.8 [$6907.4]; vs group 2, $54 419.6 [$11 324.5]; vs group 3, $61 424.0 [$17 723.8]; vs group 4, $58 508.3 [$15 174.6]; vs group 5, $58 367.0 [$13 180.5]; P for trend = .005), and prostate cancer resources, including clinician density (No. [SD] of clinicians per 100 000: group 1, 2.5 [0.3]; vs group 2, 2.5 [0.5]; vs group 3, 2.6 [0.5]; vs group 4, 2.7 [0.7]; vs group 5, 2.6 [0.5]; P for trend = .04) and prostate cancer screening (percentage [SD] of prostate-specific antigen testing among patients aged 68-74 y: group 1, 29.4% [11.8%]; vs group 2, 32.4% [11.2%]; vs group 3, 33.1% [12.7%]; vs group 4, 36.1% [9.7%]; vs group 5, 28.8% [11.8%]; P for trend = .05). Conclusions and Relevance In this cohort study of patients with prostate cancer, the adoption of commercial tissue-based genomic testing for prostate cancer was highly variable in the US at the regional level and may be associated with contextual measures related to socioeconomic status and patterns of prostate cancer care. These findings highlight factors underlying differential adoption of prognostic technologies for patients with cancer.

Abstract
OBJECTIVES To examine the effects of racial residential segregation and structural racism on the diagnosis, treatment, and outcomes of patients with prostate cancer. PATIENTS AND METHODS This retrospective cohort study examined men diagnosed with prostate cancer between 2005 and 2015. We collected data from Black and White men, aged ≥30 years, living within the 100 most populous counties participating in the Surveillance, Epidemiology, and End Results programme, a nationally representative dataset. The racial Index of Dissimilarity, a validated measure of segregation, was the primary exposure of interest. Outcomes of interest included advanced stage at diagnosis (Stage IV), surgery for localised disease (Stage I-II), and 10-year overall and cancer-specific survival. Multivariable Poisson regression analyses with robust error variance estimated the relative risk (RR) of advanced stage at diagnosis and surgery for localised disease at differing levels of segregation. Survival analysis was performed using competing hazards analysis. RESULTS Multivariable models estimating stage at diagnosis showed that the disparities between Black and White men disappeared at low levels of segregation. Disparities in receiving surgery for localised disease persisted across all levels of segregation. In racially stratified analyses, segregation had no effect on stage at diagnosis or surgical resection for Black patients. White patients saw a 56% (RR 0.42, P < 0.001) reduced risk of presenting at advanced stage and 20% increased likelihood (RR 1.20, P < 0.001) of surgery for localised disease. Black patients in the lowest segregation areas had the lowest overall mortality, but the highest cancer-specific mortality. CONCLUSIONS Our study provides evidence that residential segregation has a significant impact on Black-White disparities in prostate cancer, likely through improved outcomes for White patients and worse outcomes for Black patients in more segregated areas. These findings suggest that mitigating segregation and the downstream effects of socioeconomic factors could alleviate these disparities.

Abstract
OBJECTIVE To estimate contemporary population-based patterns of the relative burden of prostate cancer-specific mortality (PCSM) attributable to each N0M0 prostate cancer risk-group, that may guide prioritization in research, trial design, and clinical practice. METHODS We categorized 2004-2015 Surveillance, Epidemiology, and End Results database patients by risk group (low, favorable intermediate, unfavorable intermediate, high, and very highrisk). Using the Fine-Gray method, we calculated the relative burden of 10-year PCSM attributable to each risk group. RESULTS Among N = 337 162 men (6.8-year median follow-up; median age 65 years), the relative proportion of low-, favorable intermediate-, unfavorable intermediate-, high-, and very high-risk diagnoses were 29.9% (N = 100 969), 31.1% (N = 104 696), 17.9% (N = 60 360), 18.1% (N = 61 023), and 3.0% (N = 10 114). Within 10 years of diagnosis, among patients who died of prostate cancer (N = 15 064), 5.0% (N = 746) had low-risk, 13.7% (N = 2060) had favorable intermediate-risk, 16.1% (N = 2429) had unfavorable intermediate-risk, 47.8% (N = 7196) had high-risk, and 17.5% (N = 2633) had very high-risk disease at diagnosis. Patients aged 65 and older accounted for 51.9% of all diagnoses and 72.3% of 10-year PCSM. Although black patients accounted for 15.0% of low-risk diagnoses, they accounted for 20.6% of 10-year PCSM. White patients accounted for 80.3% of low-risk diagnoses and 75.7% of 10-year PCSM. CONCLUSION Although high-risk and very high-risk disease account for one-fifth of diagnoses, they account for two-thirds of 10-year PCSM. Older patients and black patients with low-risk disease accounted for a disproportionately large proportion of deaths. These findings support targeting research toward high-risk disease and ensuring adequate representation of older and black men in clinical trials.

Ethnographic investigation of patient-provider communication among African American men newly diagnosed with prostate cancer: a study protocol. BMJ Open 2020; 10:e035032. [PMID: 32759241 PMCID: PMC7409964 DOI: 10.1136/bmjopen-2019-035032] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/16/2019] [Revised: 06/02/2020] [Accepted: 06/25/2020] [Indexed: 11/21/2022] Open
Abstract
INTRODUCTION In the USA, African American men bear a disproportionate burden of prostate cancer (PCa) compared with all other groups, having a higher incidence and mortality, poorer quality of life and higher dissatisfaction with care. They are also less likely to receive guideline-concordant treatment (eg, undertreatment of aggressive disease). Inadequate patient-provider communication contributes to suboptimal care, which can be exacerbated by patients' limited health literacy, providers' lack of communication skills and time constraints in low-resource, safety net settings. This study is designed to examine the communication experiences of African American patients with PCa as they undertake treatment decision-making. METHODS AND ANALYSIS Using an ethnographic approach, we will follow 25 African American men newly diagnosed with PCa at two public hospitals, from diagnosis through treatment decision. Data sources include: (1) audio-recorded clinic observations during urology, radiation oncology, medical oncology and primary care visits, (2) field notes from clinic observations, (3) patient surveys after clinic visits, (4) two in-depth patient interviews, (5) a provider survey, and (6) in-depth interviews with providers. We will explore patients' understanding of their diagnoses and treatment options, sources of support in decision-making, patient-provider communication and treatment decision-making processes. Audio-recorded observations and interviews will be transcribed verbatim. An iterative process of coding and team discussions will be used to thematically analyse patients' experiences and providers' perspectives, and to refine codes and identify key themes. Descriptive statistics will summarise survey data. ETHICS AND DISSEMINATION To our knowledge, this is the first study to examine in-depth patient-provider communication among African American patients with PCa. For a population as marginalised as African American men, an ethnographic approach allows for explication of complex sociocultural and contextual influences on healthcare processes and outcomes. Study findings will inform the development of interventions and initiatives that promote patient-centred communication, shared decision-making and guideline-concordant care. This study was approved by the University of California San Francisco and the Alameda Health System Institutional Review Boards.

Abstract
PURPOSE The purpose of this study is to systematically review the current literature on the post-treatment survivorship experiences of African-American men with prostate cancer by exploring qualitative studies to gain a deep understanding of their survivorship experiences. METHOD We searched five databases for studies published from 2008 to 2018. We identified ten relevant qualitative studies, conducted a meta-synthesis using Noblit and Hare's meta-ethnography approach, and evaluated their quality appraisal using the validated Critical Appraisal Skills Program. RESULTS This review generated a total of four main themes and nine subthemes. The Four main themes included coping strategy, psychophysical impact, health system influence, and socioeconomic impact. Spirituality, healthy behaviors, supportive care of spouse/family/friends and non-communicating/reticent were subthemes identified in the coping strategy theme; physical well-being and sexuality and masculinity were subthemes in the psychophysical impact theme; healthcare provider interaction and treatment decision-making were subthemes identified in the health system influence theme, and health insurance status was the subtheme in the socioeconomic impact theme. CONCLUSION Our findings reveal that the experiences of African-American prostate cancer survivors are complex and multidimensional. IMPLICATIONS FOR CANCER SURVIVORS This review highlights the need for further studies with African-American prostate cancer survivors, precisely identify their needs and plan a culturally appropriate intervention to meet those needs.

Abstract
Background The United States Preventative Services Task Force (USPSTF) guideline on Prostate Specific Antigen (PSA)-based prostate cancer screening evolved both in 2008 (Grade I for men < 75 years and Grade D for men > 75 years) and in 2012 (Grade D for all ages). Materials and methods A statewide cancer registry operated by the Pennsylvania Department of Health was accessed to analyze over a 15-year period prostate cancer rates across different categories including age, stage, and geographic distribution. Results Local prostate cancer rates decreased significantly when comparing before and after USPSTF's guideline changes: 2002-2008 vs. 2009-2012 vs. 2013-2016 (p < 0.005). Conversely, the distant cancer rates increased significantly in Caucasian men (but not in African American men) (p = 0.0078). In age group analysis, distant cancer rates increased significantly in all age ranges, most notably in younger men (50-59 years). No observed difference in the trend of distant cancer rates when considering rural versus urban counties. Conclusions Incident prostate cancer cases diagnosed in Pennsylvania have decreased over the past 15 years with a recent rise in distant carcinomas potentially attributable to the USPSTF recommendations against PSA-based screening. Although the USPSTF revised their PSA-based prostate cancer screening guideline in 2018 (Grade C for men 55-69 years and Grade D for men > 70 years), the implications of the aforementioned observations on mortality outcomes merit further follow-up.

Abstract
INTRODUCTION Past studies comparing perioperative outcomes of hysterectomy (HYST) and uterine artery embolization (UAE) do not control for demographically and insurer diverse populations. This study sought to identify the 30‑day readmission, 15‑day complication, and minimum 1‑year surveillance reintervention rates of diverse, propensity matched patients undergoing UAE or HYST for uterine leiomyoma. METHODS Adults from the New York's Statewide Planning and Research Cooperative System (SPARCS) database 2009‑2013 who underwent HYST or UAE for uterine leiomyoma were retrospectively reviewed and 1:1 propensity matched. Univariate analysis compared demographics, complications, readmissions, and reintervention rates. Binary logistic and linear regression models identified independent predictors of outcomes. RESULTS A total of 682 patients were identified, where the number (n) of patients in each cohort was n=341, HYST, and n=341, UAE. Significance levels are shown with p values. No significant differences were identified between HYST and UAE demographics, complication (2.60% HYST vs 2.90% UAE, p=0.816) or readmission rates (3.20% HYST vs 3.80% UAE, p=0.678); 0.30% of UAE patients had a reintervention UAE and 2.90% of UAE patients had reintervention hysterectomy. HYST patients had a significantly longer average length of stay (2.59 days HYST vs 1.63 days UAE, p<0.001). The Deyo-Charlson (Deyo) comorbidity score positively predicted any complication with odds ratio=34.262, 95% confidence interval [4.938, 237.725], and p<0.001, but did not predict readmissions. CONCLUSION HYST patients had significantly longer hospital stays. UAE and HYST had comparable readmission and complication rates. The Deyo comorbidity score was a significant predictor of any complication. This study supports the safety and efficacy of UAE when compared to HYST in demographic and insurer diverse populations.

Abstract
INTRODUCTION Compared to low-volume hospitals, high-volume hospitals are associated with lower rates of perioperative morbidity and mortality. However, access to high-volume hospitals is unequal. We investigated racial and socioeconomic disparities among patients undergoing surgery for genitourinary malignancies at high-volume hospitals. MATERIAL AND METHODS We queried the National Cancer Database from 2004-2015 to identify patients who underwent radical prostatectomy, radical cystectomy, and nephrectomy for nonmetastatic prostate cancer, muscle-invasive urothelial bladder cancer, and kidney cancer, respectively. Hospitals were ranked based on their annual volume for the given procedure. The endpoint of our study was receipt of treatment at a high-volume hospital. Multivariable logistic regression models were used to identify predictors of treatment at a high-volume hospital. RESULTS Our final cohort consisted of 397,242 prostate cancer patients, 39,480 bladder cancer patients, and 292,095 kidney cancer patients. For prostate and bladder cancer, Black race was associated with lower odds of treatment at a high-volume hospital (Odds Ratio [OR] 0.83, 95% confidence interval [CI] 0.79-0.87 and 0.71, 95%CI 0.58-0.87; reference: White). Higher education level and private insurance status were associated with greater odds of treatment across all 3 procedures (strongest effect for prostate cancer; higher education level: OR 1.63 [1.58-1.68]; private insurance 1.86 [1.77-1.97]). Moreover, an interaction was found between race and study period for all cancers examined (P < 0.001). Subgroup analyses revealed that Black patients were more likely to undergo radical prostatectomy at high-volume hospitals in 2013-2015 (OR 0.98, 95%CI 0.94-1.02) compared to 2004-2006 (OR 0.83, 95%CI 0.79-0.87). CONCLUSION Across all procedures, patients with lower education status and lack of insurance were less likely to be treated at high-volume hospitals. For prostate cancer and bladder cancer, Black race was a negative predictor of treatment at high-volume hospitals. Further studies are needed to understand the root causes for this inequity.

Abstract
Extensive research has examined socioeconomic factors influencing prostate cancer (PCa) disparities. However, to what extent molecular and genetic mechanisms may also contribute to these inequalities still remains elusive. Although various in vitro, in vivo, and population studies have originated to address this issue, they are often very costly and time-consuming by nature. In this work, we attempt to explore this problem by a preliminary study, where a joint deep latent variable model (DLVM) is proposed to in silico quantify the personalized and race-specific effects that a genomic aberration may exert on the Gleason Score (GS) of each individual PCa patient. The core of the proposed model is a deep variational autoencoder (VAE) framework, which follows the causal structure of inference with proxies. Extensive experimental results on The Cancer Genome Atlas (TCGA) 270 European-American (EA) and 43 African-American (AA) PCa patients demonstrate that ERG fusions, somatic mutations in SPOP and ATM, and copy number alterations (CNAs) in ERG are the statistically significant genomic factors across all low-, intermediate-, and high-grade PCa that may explain the disparities between these two groups. Moreover, compared to a state-of-the-art deep inference method, our proposed method achieves much higher precision in causal effect inference in terms of the impact of a studied genomic aberration on GS. Further validation on an independent set and the assessment of the genomic-risk scores along with corresponding confidence intervals not only validate our results but also provide valuable insight to the observed racial disparity between these two groups regarding PCa metastasis. The pinpointed significant genomic factors may shed light on the molecular mechanism of cancer disparities in PCa and warrant further investigation.

Abstract
BACKGROUND In prior reports from population-based databases, black patients with extremity soft tissue sarcoma (ESTS) have lower reported rates of limb-sparing surgery and adjuvant treatment. The objective of this study was to compare the multimodality treatment of ESTS between black and white patients within a universally insured and equal-access health care system. METHODS Claims data from TRICARE, the US Department of Defense insurance plan that provides health care coverage for 9 million active-duty personnel, retirees, and dependents, were queried for patients younger than 65 y with ESTS who underwent limb-sparing surgery or amputation between 2006 and 2014 and identified as black or white race. Multivariable logistic regression analysis was used to evaluate the impact of race on the utilization of surgery, chemotherapy, and radiation. RESULTS Of the 719 patients included for analysis, 605 patients (84%) were white and 114 (16%) were black. Compared with whites, blacks had the same likelihood of receiving limb-sparing surgery (odds ratio [OR], 0.861; 95% confidence interval [95% CI], 0.284-2.611; P = 0.79), neoadjuvant radiation (OR, 1.177; 95% CI, 0.204-1.319; P = 0.34), and neoadjuvant (OR, 0.852; 95% CI, 0.554-1.311; P = 0.47) and adjuvant (OR, 1.211; 95% CI, 0.911-1.611; P = 0.19) chemotherapy; blacks more likely to receive adjuvant radiation (OR, 1.917; 95% CI, 1.162-3.162; P = 0.011). CONCLUSIONS In a universally insured population, racial differences in the rates of limb-sparing surgery for ESTS are significantly mitigated compared with prior reports. Biologic or disease factors that could not be accounted for in this study may contribute to the increased use of adjuvant radiation among black patients.

Variation in Positive Surgical Margin Status After Radical Prostatectomy for pT2 Prostate Cancer. Clin Genitourin Cancer 2019; 17:e1060-e1068. [PMID: 31303561 DOI: 10.1016/j.clgc.2019.06.008] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/21/2019] [Accepted: 06/13/2019] [Indexed: 11/19/2022]
Abstract
INTRODUCTION We evaluated patient, hospital, and cancer-specific factors associated with positive surgical margin (PSM) variability after radical prostatectomy in pT2 prostate cancer in the United States. PATIENTS AND METHODS A total of 45,426 men from 1152 hospitals with pT2 prostate cancer and known margin status after radical prostatectomy were identified using the National Cancer Database (2010-2015). Data on patient, cancer, hospital factors, and surgical approach were extracted. A mixed effects logistic regression model was computed to examine factors associated with PSM and partial R2 values to assess the relative contributions of patient, cancer, and hospital variables to PSM status. RESULTS Median PSM rate of 8.5% (interquartile range, 5.2%-13.0%). Robotic (odds ratio [OR], 0.90; 95% confidence interval [CI], 0.83-0.99) and laparoscopic (OR, 0.74; 95% CI, 0.64-0.90) surgical approach, academic institution (OR, 0.87; 95% CI, 0.76-1.00) and high hospital surgical volume (>297 cases [OR], 0.83; 95% CI, 0.70-0.99) were independently associated with a lower PSM. Black men (OR, 1.13; 95% CI, 1.01-1.26) and adverse cancer-specific features (prostate-specific antigen [PSA], 10-20; PSA >20; cT3 stage; Gleason 7, 8, 9-10; all P > .01) were independently associated with a higher PSM. Patient-specific, hospital-specific, and cancer-specific factors had a contribution of 2.3%, 3.9%, and 15.2%, respectively, to the variation in PSM. Facility had a contribution of 23.7% to the variation in PSM. CONCLUSION Cancer-specific factors account for 15.2% of PSM variation with the remaining 84.8% of PSM variation due to patient, hospital, and other factors not accounted within the model. Noncancer-specific factors represent addressable factors that are important for policy-makers in efforts to improve patient outcome.

Abstract
OBJECTIVE Patients with refractory epilepsy are at a high risk of complications but may not receive the same level of care across racial groups. We aimed to ascertain racial inequalities and trends in the use of a vagal nerve stimulator (VNS) among adult patients with refractory epilepsy. METHODS A total of 24 159 adults (18 years and older) with refractory epilepsy from the National Inpatient Sample between the years 2006 and 2014 were included in this analysis. We used a multivariate logistic regression analysis to evaluate independent predictors of VNS use among patients with refractory epilepsy. Covariates included gender, age, insurance type, and household income. In addition, we evaluated for trends in VNS use over the 9-year period of data collection. RESULTS A total of 1.56% of patients with refractory epilepsy had used a VNS between 2006 and 2014. Overall, there was a trend of decreased use of a VNS between 2006-2008 (2.1%) and 2012-2014 (0.9%). In the adjusted multivariate logistic regression analysis, blacks (odds ratio [OR] = 0.52, 95% confidence interval [CI] = 0.35-0.77) were significantly less likely to have used a VNS relative to non-Hispanic whites. Additional factors independently associated with a decreased likelihood of VNS use were age > 65 years (OR = 0.51, 95% CI = 0.28-0.95) and years 2012-2014 (OR = 0.44, 95% CI = 0.28-0.67). SIGNIFICANCE There was a trend toward a decrease in the use of a VNS among adult patients with refractory epilepsy. Our results also suggest that black patients with refractory epilepsy were less likely to receive a VNS independently of other variables. Increased work toward effectively reducing racial disparities in access to quality epilepsy care is crucial.

Insurance status as a modifier of the association between race and stage of prostate cancer diagnosis in Florida during 1995 and 2013. Cancer Epidemiol 2019; 59:104-108. [PMID: 30731402 DOI: 10.1016/j.canep.2019.01.019] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/07/2018] [Revised: 01/25/2019] [Accepted: 01/28/2019] [Indexed: 10/27/2022]
Abstract
BACKGROUND Cancer stage at diagnosis is a critical prognostic factor regarding a patient's health outcomes. It has yet to be shown whether insurance status across different race has any implications on the stage of disease at the time of diagnosis. This study aimed to investigate whether insurance status was a modifier of the association between race and stage of previously undetected prostate cancer at the time of diagnosis in Florida between 1995 and 2013. METHODS Secondary data analysis of a cross-sectional survey using information from the Florida Cancer Data System (n = 224,819). Study participants included black and white males diagnosed with prostate cancer in Florida between 1995 and 2013. The main outcome variable was stage of prostate cancer at diagnosis. The main independent variable was race (black vs white). Adjusted logistic regression models were used to explore the association between race, insurance status and stage at diagnosis. Odds ratios (OR) and 95% confidence intervals (95% CI) were calculated. RESULTS Black males were more likely to be diagnosed with late stage prostate cancer (OR 1.31; 95% CI 1.27-1.35). Being uninsured (OR 2.28; 95% CI 2.13-2.45) or having Medicaid (OR 1.84; 95% CI 1.70-1.98) was associated with a diagnosis of late stage cancer. Stratified analysis for health insurance revealed that blacks had an increased risk for late stage cancer if uninsured (OR 1.29; 95% CI 1.07-1.55) and if having Medicare (OR 1.39; 95% CI 1.31-1.48). CONCLUSION Insurance status may modify the effect of race on late stage prostate cancer in black patients.

Cancer 2019; 125:453-462. [PMID: 30444526 PMCID: PMC6340740 DOI: 10.1002/cncr.31826] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/16/2018] [Revised: 08/27/2018] [Accepted: 10/01/2018] [Indexed: 01/07/2023]
Abstract
BACKGROUND Surgical and medical androgen deprivation therapy (ADT) strategies are comparable in their ability to suppress serum testosterone levels as treatment in patients with metastatic prostate cancer but differ with regard to cost and impact on quality of life. Medical ADT is associated with better long-term quality of life due to the flexibility of possible therapy interruption but comes with a higher cumulative cost. In the current study, the authors examined whether surgical ADT (ie, bilateral orchiectomy) was used differentially by race/ethnicity and other social factors. METHODS The authors identified patients with metastatic disease at the time of diagnosis through the California Cancer Registry. The association between race/ethnicity and receipt of surgical ADT was modeled using multivariable Firth logistic regression adjusting for age, Gleason score, prostate-specific antigen level, clinical tumor and lymph node classification, neighborhood socioeconomic status (SES), insurance, marital status, comorbidities, initial treatment (radiotherapy, chemotherapy), location of care, rural/urban area of residence, and year of diagnosis. RESULTS The authors examined a total of 10,675 patients with metastatic prostate cancer, 11.4% of whom were non-Hispanic black, 8.4% of whom were Asian/Pacific Islander, 18.5% of whom were Hispanic/Latino, and 60.5% of whom were non-Hispanic white. In the multivariable model, patients found to be more likely to receive surgical ADT were Hispanic/Latino (odds ratio [OR], 1.32; 95% confidence interval [95% CI], 1.01-1.72), were from a low neighborhood SES (OR, 1.96; 95% CI, 1.34-2.89) or rural area (OR, 1.49; 95% CI, 1.15-1.92), and had Medicaid/public insurance (OR, 2.21; 95% CI, 1.58-3.10). Patients with military/Veterans Affairs insurance were significantly less likely to receive surgical ADT compared with patients with private insurance (OR, 0.34; 95% CI, 0.13-0.88). CONCLUSIONS Race/ethnicity, neighborhood SES, and insurance status appear to be significantly associated with receipt of surgical ADT. Future research will need to characterize other differences in initial treatments among men with advanced prostate cancer based on race/ethnicity and aim to better understand what factors drive the association between surgical ADT among men of Hispanic origin or those from areas with low neighborhood SES.

Abstract
BACKGROUND There are race-based differences in bladder cancer survival. To better understand this phenomenon, this study was designed to assess the statistical contributions of tumor, treatment, and access variables to race-based differences in survival. METHODS Data were extracted from the National Cancer Data Base on black and white adults with muscle-invasive bladder cancer from 2004 to 2015. The impact of tumor, access, and treatment variables on differences in survival was inferred by the performance of sequential propensity score-weighted analyses in which black and white patients were balanced with respect to demographics and health status (comorbidities) tumor characteristics, treatment, and access-related variables. The propensity score-weighted hazard of death (black vs white) was calculated after each iteration. RESULTS This study identified 44,577 patients with a median follow-up of 77 months. After demographics and health status were balanced, black race was associated with 18% worse mortality (hazard ratio, 1.18; 95% confidence interval [CI], 1.12-1.25; P < .001). Balancing by tumor characteristics reduced this to 16%, balancing by treatment reduced this to 10%, and balancing by access-related variables resulted in no difference. Access-related variables explained 40% (95% CI, 22.9%-57.0%) of the excess risk of death in blacks, whereas treatment factors explained 35% (95% CI, 22.2%-46.9%). The contribution of tumor characteristics was not significant. CONCLUSIONS In the models, differences in survival for black and white patients with bladder cancer are best explained by disparities in access and treatment, not tumor characteristics. Access to care is likely a key factor in racial disparities in cancer.

Abstract
INTRODUCTION The purpose of this research is to gather, collate, and identify key factors commonly studied in localized prostate cancer (LPC) treatment decision-making in Canada and the U.S. METHODS This scoping review uses five databases (Medline, EMBASE, CINAHL, AMED, and PsycInfo) to identify relevant articles using a list of inclusion and exclusion criteria applied by two reviewers. A list of topics describing the themes of the articles was extracted and key factors were identified using principal component analysis (PCA). A word cloud of titles and abstracts of the relevant articles was created to identify complementary results to the PCA. RESULTS This review identified 77 relevant articles describing 32 topics related to LPC treatment decision-making. The PCA grouped these 32 topics into five key factors commonly studied in LPC treatment decision-making: 1) treatment type; 2) socioeconomic/demographic characteristics; 3) personal reasons for treatment choice; 4) psychology of treatment decision experience; and 5) level of involvement in the decision-making process. The word cloud identified common phrases that were complementary to the factors identified through the PCA. CONCLUSIONS This research identifies several possible factors impacting LPC treatment decision-making. Further research needs to be completed to determine the impact that these factors have in the LPC treatment decision-making experience.

Abstract
The purpose of the study was to explore attitudes/beliefs in men attending an urban health fair to explore barriers to prostate cancer (PCa) screening. Five hundred and forty-four men attending the PCa booth at the fair in 2014 or 2015 completed questionnaires about PCa. Data were examined using Pearson’s χ2, Fisher’s Exact, and Wilcoxon rank tests after grouping men by African American (AA) and non-African American ethnicity. Three hundred and twenty-six (60%) men were AA and two hundred and eighteen (40%) were non-AA (89% white). Median age (54 vs. 56 years) and prior PCa screening were similar between AA and non-AA; income (p = .044) and education (p = .0002) differed. AA men were less likely to have researched prostate-specific antigen (PSA) on the internet (p = .003), but more used TV (p = .003) and media (p = .0014) as information sources. Family members had a stronger influence over screening decisions for AA men (p = .005). After reading PSA information, AA men were more likely to still be confused (p = .008). A higher proportion of AA men were less worried about dying from PCa (p = .0006), but would want treatment immediately instead of watchful waiting (p < .0001). Interestingly, a higher proportion of AA men indicated that they would prefer not to know if they had PCa (p = .001). Ultimately, more AA men had a PSA done (98.4% vs. 95.1%; p = .031). When considering screening eligible men, a higher proportion of AA men had an abnormal PSA (13.1% vs. 5.3%; p = .037). AA men’s beliefs surrounding PCa differ from non-AA men, and should be considered when developing culturally appropriate education, screening, and treatment strategies for this group.

Abstract
BACKGROUND We addressed the hypothesis that individual-level factors act jointly with social and built environment factors to influence overall survival for men with prostate cancer and contribute to racial/ethnic and socioeconomic (SES) survival disparities. METHODS We analyzed multi-level data, combining (1) individual-level data from the California Collaborative Prostate Cancer Study, a population-based study of non-Hispanic White (NHW), Hispanic, and African American prostate cancer cases (N = 1800) diagnosed from 1997 to 2003, with (2) data on neighborhood SES (nSES) and social and built environment factors from the California Neighborhoods Data System, and (3) data on tumor characteristics, treatment and follow-up through 2009 from the California Cancer Registry. Multivariable, stage-stratified Cox proportional hazards regression models with cluster adjustments were used to assess education and nSES main and joint effects on overall survival, before and after adjustment for social and built environment factors. RESULTS African American men had worse survival than NHW men, which was attenuated by nSES. Increased risk of death was associated with residence in lower SES neighborhoods (quintile 1 (lowest nSES) vs. 5: HR = 1.56, 95% CI: 1.11-2.19) and lower education ( CONCLUSION Both individual- and contextual-level SES influence overall survival of men with prostate cancer. Additional research is needed to identify the mechanisms underlying these robust associations.

Abstract
Prostate cancer (PCa) is the most commonly diagnosed malignancy in males, and, in the United States, is the second leading cause of cancer-related death for men older than 40 years. There is a higher incidence of PCa for African Americans (AAs) than for European-Americans (EAs). Investigations related to the incidence of PCa-related health disparities for AAs suggest that there are differences in the genetic makeup of these populations. Other differences are environmentally induced (e.g., diet and lifestyle), and the exposures are different. Men who immigrate from Eastern to Western countries have a higher risk of PCa than men in their native countries. However, the number of immigrants developing PCa is still lower than that of men in Western countries, suggesting that genetic factors are involved in the development of PCa. Altered genetic polymorphisms are associated with PCa progression. Androgens and the androgen receptor (AR) are involved in the development and progression of PCa. For populations with diverse racial/ethnic backgrounds, differences in lifestyle, diet, and biology, including genetic mutations/polymorphisms and levels of androgens and AR, are risk factors for PCa. Here, we provide an immuno-biological perspective on PCa in relation to racial/ethnic disparities and identify factors associated with the disproportionate incidence of PCa and its clinical outcomes.
