Abstract
OBJECTIVE To identify the association between multidisciplinary clinic (MDC) management and disparities in treatment for patients with pancreatic cancer. BACKGROUND Socioeconomic status (SES) predicts treatment and survival for pancreatic cancer. Multidisciplinary clinics (MDCs) may improve surgical management for these patients. METHODS This is a retrospective cohort study (2010-2018) of all pancreatic cancer patients within a large, regional hospital system with a high-volume pancreatic cancer MDC. The primary outcome was receipt of treatment (surgery, chemotherapy, radiation, clinical trial participation, and palliative care); the secondary outcomes were overall survival and MDC management. Multiple logistic regressions were used for binary outcomes. Survival was analyzed using Kaplan-Meier survival analysis, Cox proportional hazards, and inverse probability of treatment weighting (IPTW). RESULTS Of the 4141 patients studied, 1420 (34.3%) were managed by the MDC. MDC management was more likely for patients who were younger age, married, and privately insured, while less likely for low SES patients (all p < 0.05). MDC patients were more likely to receive all treatments, including neoadjuvant chemotherapy (OR 3.33, 95% CI 2.82-3.93), surgery (OR 1.39, 95% CI 1.15-1.68), palliative care (OR 1.21, 95% CI 1.05-1.38), and clinical trial participation (OR 3.76, 95% CI 2.86-4.93). Low SES patients were less likely to undergo surgery outside of the MDC (OR 0.47, 95% CI 0.31-0.73) but there was no difference within the MDC (OR 1.10, 95% CI 0.68-1.77). Across multiple survival analyses, low SES predicted inferior survival outside of the MDC, but there was no association among MDC patients. CONCLUSION Multidisciplinary team-based care increases rates of treatment and eliminates socioeconomic disparities for pancreatic cancer patients.

Front Oncol 2024; 14:1325614. [PMID: 38450190 PMCID: PMC10915648 DOI: 10.3389/fonc.2024.1325614] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/21/2023] [Accepted: 01/18/2024] [Indexed: 03/08/2024] Open
Abstract
This review focuses on the critical role of epigenetic modifications in solid tumor metastasis, particularly in people of African ancestry. Epigenetic alterations, such as DNA methylation, histone modifications, alterations in non-coding RNAs, and mRNA methylation, significantly influence gene expression, contributing to cancer development and progression. Despite the primary focus on populations of European, American, and Asian descent in most cancer research, this work emphasizes the importance of studying the unique genetic and epigenetic landscapes of African populations for a more inclusive approach in understanding and treating cancer. Insights from this review have the potential to pave the way for the development of effective, tailored treatments, and provide a richer resource for understanding cancer progression and metastasis. Specific focus was placed on the role of DNA methylation, histone modifications, non-coding RNAs, and mRNA methylation in solid tumor metastasis, including how these modifications contribute to the regulation of tumor suppressor genes and oncogenes, influence cellular pathways and signaling, and interact with the immune system. Moreover, this review elaborates on the development of epigenetic-targeted therapeutic strategies and the current advances in this field, highlighting the promising applications of these therapies in improving outcomes for African ancestry populations disproportionately affected by certain types of cancer. Nevertheless, this work acknowledges the challenges that lie ahead, particularly the under-representation of African populations in cancer genomic and epigenomic studies and the technical complications associated with detecting subtle epigenetic modifications. Emphasis is placed on the necessity for more inclusive research practices, the development of more robust and sensitive methods for detecting and interpreting epigenetic changes, and the understanding of the interplay between genetic and epigenetic variations. The review concludes with an optimistic outlook on the future of epigenetic research in People of African ancestry, urging the concerted efforts of researchers, clinicians, funding agencies, and policymakers to extend the benefits of this research to all populations.

Disparities With Systemic Therapies for Black Men Having Advanced Prostate Cancer: Where Do We Stand? J Clin Oncol 2024; 42:228-236. [PMID: 37890125 PMCID: PMC10824384 DOI: 10.1200/jco.23.00949] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/28/2023] [Revised: 08/08/2023] [Accepted: 08/23/2023] [Indexed: 10/29/2023] Open
Abstract
PURPOSE Prostate cancer represents the most common cancer diagnosis in Black men and is the second leading cause of cancer death in this population. Multilevel disparities have been well-documented in Black men with prostate cancer and play a role in poorer survival outcomes when compared with White men with prostate cancer. In this review, we highlight the changing trend in disparities for systemic therapy outcomes in Black men diagnosed with metastatic prostate cancer. METHODS We reviewed data from real-world registries and prospective clinical trials with a particular focus on equal access settings to compare outcomes to systemic therapies between Black and White men with metastatic prostate cancer. RESULTS In metastatic prostate cancer, there is growing evidence to suggest that Black men may have similar, if not better, outcomes to systemic therapies than White men with advanced disease, as corroborated by prospective studies and clinical trials where health care delivery and follow-up are more likely to be standardized. CONCLUSION This review illustrates the importance of nonbiological drivers of racial disparities in Black men with advanced prostate cancer. Mitigating barriers to health care access and delivery as well as including participation in clinical trials will be pivotal to ongoing efforts to address disparities in systemic therapy outcomes for Black men with metastatic prostate cancer.

Mumuni S, O’Donnell C, Doody O. The Risk Factors and Screening Uptake for Prostate Cancer: A Scoping Review. Healthcare (Basel) 2023; 11:2780. [PMID: 37893854 PMCID: PMC10606491 DOI: 10.3390/healthcare11202780] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/11/2023] [Revised: 10/11/2023] [Accepted: 10/17/2023] [Indexed: 10/29/2023] Open
Abstract
OBJECTIVES The purpose of this scoping review was to identify the risk factors and screening uptake for prostate cancer. DESIGN Scoping review. METHODS Arksey and O'Malley's framework guided this review; five databases (Cumulative Index to Nursing and Allied Health Literature (CINAHL), MEDLINE, PsycINFO, Academic Search Complete and Cochrane Library) and grey literature were searched. Screening was undertaken against predetermined inclusion criteria for articles published before July 2023 and written in English. This review is reported in line with PRISMA-Sc. RESULTS 10,899 database results were identified; 3676 papers were removed as duplicates and 7115 papers were excluded at title and abstract review. A total of 108 papers were full-text reviewed and 67 were included in the review. Grey literature searching yielded no results. Age, family history/genetics, hormones, race/ethnicity, exposure to hazards, geographical location and diet were identified as risk factors. Prostatic antigen test (PSA), digital rectal examination (DRE), transrectal ultrasound (TRUS), magnetic resonance imaging (MRI), magnetic resonance spectroscopic imaging (MRSI) and prostate biopsy were identified as screening/diagnostic methods. The evidence reviewed highlights moderate knowledge and screening uptake of prostate cancer with less than half of men reporting for PSA screening. On the other hand, there is a year-to-year increase in PSA and DRE screening, but factors such as poverty, religion, culture, communication barriers, language and costs affect men's uptake of prostate cancer screening. CONCLUSION As prostate cancer rates increase globally, there is a need for greater uptake of prostate cancer screening and improved health literacy among men and health workers. There is a need to develop a comprehensive prostate cancer awareness and screening programme that targets men and addresses uptake issues so as to provide safe, quality care. STRENGTHS AND LIMITATIONS OF THIS STUDY (1) A broad search strategy was utilised incorporating both databases and grey literature. (2) The PRISMA reporting guidelines were utilised. (3) Only English language papers were included, and this may have resulted in relevant articles being omitted.

Abstract
Gold standard genomic datasets severely under-represent non-European populations, leading to inequities and a limited understanding of human disease [1-8]. Therapeutics and outcomes remain hidden because we lack insights that we could gain from analyzing ancestry-unbiased genomic data. To address this significant gap, we present PhyloFrame, the first-ever machine learning method for equitable genomic precision medicine. PhyloFrame corrects for ancestral bias by integrating big data tissue-specific functional interaction networks, global population variation data, and disease-relevant transcriptomic data. Application of PhyloFrame to breast, thyroid, and uterine cancers shows marked improvements in predictive power across all ancestries, less model overfitting, and a higher likelihood of identifying known cancer-related genes. The ability to provide accurate predictions for underrepresented groups, in particular, is substantially increased. These results demonstrate how AI can mitigate ancestral bias in training data and contribute to equitable representation in medical research.

Abstract
Advanced prostate cancer (aPC) in Black men was reported to present with aggressive features and to be associated with poor prognosis. Herein, we compared the cell-free DNA (cfDNA) genomic landscape of aPC in Black vs White men. Patients (pts) with aPC from 6 academic institutions and available cfDNA comprehensive genomic profiling (CGP) were included. Association between mutated genes and race was evaluated using Barnard’s test and a Probabilistic Graphical Model (PGM) machine learning approach. Analysis included 743 aPC pts (217 Black, 526 White) with available cfDNA CGP. The frequency of alterations in the androgen receptor gene was significantly higher in Black vs White men (55.3% vs 35% respectively, P < .001). Additionally, alterations in EGFR, MYC, FGFR1, and CTNNB1 were present at higher frequencies in Black men. PGM analysis and Barnard’s test were concordant. Findings from the largest cohort of Black men with aPC undergoing cfDNA CGP may guide further drug development in these men.

Abstract
INTRODUCTION Prostate cancer (PCa) is a heterogenous disease with multiple etiological factors playing a role in its development. Recently, chronic and systemic inflammatory conditions such as inflammatory bowel disease were identified as key risk factors influencing its development. The study aimed to evaluate the relationship between diverticular disease (DD) (local and acute inflammation) and PCa. METHODS Hypertensive patients with DD and hypertensive controls were identified between 1995 and 2010 from the Statewide Planning and Research Cooperative System database. Cohorts were queried for PCa incidence through 2015. Univariable and multivariable logistic regression analyses were used for determining independent predictors of PCa diagnosis. RESULTS A total of 51,353 patients with DD and 111,541 controls were identified. In all, 6.26% of DD developed PCa, and 3.71% of controls developed PCa (p < 0.01). DD was a significant risk factor for PCa (OR: 1.27 CI: 1.19-1.34, p < 0.01). On subgroup analysis, the patients diagnosed with DD <50 years old had an OR of 3.39 for PCa (CI: 2.52-4.56, p < 0.01), age 50-59 had an OR of 2.12 (CI: 1.86-2.15, p < 0.01), and age 60-69 had an OR of 1.20 (CI: 1.10-1.31, p < 0.01). Finally, age and race stratification showed that white patients <50 had an OR of 2.56 (CI: 1.75-3.76, p < 0.01), while black patients <50 had an OR of 3.98 (CI: 2.61-6.07, p < 0.01). The trend in differing odds between these populations was the same for age groups 50-59 and 60-69. CONCLUSION Our analysis shows that DD is associated with diagnosis of PCa in hypertensive men. Importantly, the earlier the diagnosis of DD, the higher the odds for development of PCa, particularly in black men.

Abstract
PURPOSE OF REVIEW African-American men in the USA have a higher incidence of and mortality from prostate cancer (PCa), with a longstanding debate about the cause for these worse outcomes. This review examines differences in tumour biology and socioeconomics for African-American and Non-Hispanic White (NHW) men to answer the question 'why AA men face higher risks for lethal PCa' and draw a management consensus to redress the imbalance. RECENT FINDINGS Recent evidence from over the past 2 years suggests the reasons why African-American men face a higher risk of lethal PCa are multifactorial, with contributions from differences in tumour biology as well as socioeconomic and healthcare access factors. Regarding tumour biology, genomic and transcriptome profiling suggests African-American men have upregulated expression of genes related to inflammatory pathways with downregulation of DNA repair genes. In contrast, NHW men have higher DNA repair pathways and metabolic pathways involving glycolysis and cell cycle activity. In addition, epidemiological evidence suggests equal healthcare access ensures equal PCa specific outcomes, implying African-American men's disease is not inherently more lethal. However, differences in tumour biology remain, which may explain specific differences in PCa incidence and the clinical findings of African-American men's increased response to immunotherapy and radiotherapy in recent trials. SUMMARY Regardless of racial differences in disease outcomes and the factors causing them, African-American and NHW men seem to have diseases unique to their ancestry. This supports the exploration of personalized PCa treatment approaches, leveraging translational basic science research to uncover these differences and devise specific individualized methods therapeutic regimes to address them.

Abstract
Disparities in cancer incidence and outcome are common among the racial and ethnical minorities in the United States and are of significant social and clinical concern. Prostate cancer is the most commonly diagnosed non-cutaneous malignancy in American men and exhibits substantial racial disparities with African American men bearing the highest burden in terms of incidence and mortality. A multitude of factors, including socioeconomic, behavioral, and access to healthcare, have been implicated as the underlying causes of such disparities. More recent data also suggest that there are inherent molecular and biological differences in prostate tumors of patients having distinct racial backgrounds. Tumor microenvironment has tremendous impact on the course of cancer progression and clinical outcome and may also contribute to the racial disparities observed in prostate cancer. Therefore, a better understanding of critical differences in the tumor microenvironment components may provide newer directions to study the biological causes of prostate cancer health disparities and may identify novel therapeutic targets. This review discusses the findings related to the tumor microenvironment differences between African American and Caucasian American prostate cancer patients and makes suggestion regarding their potential significance in prostate cancer disparities.

Abstract
INTRODUCTION Patients with psoriatic arthritis (PsA) and ankylosing spondylitis (AS) may receive suboptimal care, and differences in care by race/ethnicity, sex, and insurance coverage are not well studied. METHODS This was a descriptive, retrospective cross-sectional US claims database analysis utilizing the Medicaid multi-state segment of the IBM® MarketScan® Commercial Claims and Encounters Supplemental Database and Optum Insight Clinformatics® Data Mart database for 2019. Patients aged ≥ 18 years with PsA or AS and continuous medical and pharmacy coverage were included. Outcomes evaluated were prevalence and percentage of patients receiving biologic disease-modifying antirheumatic drugs (bDMARDs)/targeted synthetic DMARDs (tsDMARDs) or visiting a rheumatologist. Outcomes were stratified by race/ethnicity, sex, and insurance coverage, with outcomes determined for commercial insurance, Medicare, and Medicaid enrollees. Differences observed in outcomes were numerical in nature. RESULTS Prevalences of PsA and AS were highest for Medicare enrollees (320 and 156 per 100,000 persons [0.32 and 0.16%], respectively) and lowest for Medicaid enrollees (132 and 71 per 100,000 persons [0.13 and 0.07%], respectively). White patients had the greatest prevalence versus patients of other races/ethnicities. Females had a higher prevalence of PsA than males, while AS prevalence was generally lower for females versus males for each insurance category. The percentage of patients prescribed bDMARDs/tsDMARDs was highest for commercial insurance enrollees (PsA 63%, AS 43%) and lowest for Medicare enrollees (PsA 21%, AS 11%). The proportion of patients who saw a rheumatologist was lower for Medicaid enrollees (PsA 12%, AS 10%) than for commercial insurance or Medicare enrollees (PsA 68%, 55%; AS 67%, 42%). For commercial insurance and Medicare enrollees, the percentage of patients visiting a rheumatologist was similar by race/ethnicity but higher for females versus males. CONCLUSIONS The prevalence and treatment of PsA and AS differs by race/ethnicity, insurance coverage, and sex in the USA. Efforts for improving access to care are needed to improve outcomes among all patients.

Cancer Rep (Hoboken) 2021; 4:e1340. [PMID: 33599076 PMCID: PMC8551995 DOI: 10.1002/cnr2.1340] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/26/2020] [Revised: 11/22/2020] [Accepted: 12/02/2020] [Indexed: 12/28/2022] Open
Abstract
Background African Americans (AAs) in the United States are known to have a higher incidence and mortality for Prostate Cancer (PCa). The drivers of this epidemiological disparity are multifactorial, including socioeconomic factors leading to lifestyle and dietary issues, healthcare access problems, and potentially tumor biology. Recent findings Although recent evidence suggests once access is equal, AA men have equal outcomes to Caucasian American (CA) men, differences in PCa incidence remain, and there is much to do to reverse disparities in mortality across the USA. A deeper understanding of these issues, both at the clinical and molecular level, can facilitate improved outcomes in the AA population. This review first discusses PCa oncogenesis in the context of its diverse hallmarks before benchmarking key molecular and genomic differences for PCa in AA men that have emerged in the recent literature. Studies have emphasized the importance of tumor microenvironment that contributes to both the unequal cancer burden and differences in clinical outcome between the races. Management of comorbidities like obesity, hypertension, and diabetes will provide an essential means of reducing prostate cancer incidence in AA men. Although requiring further AA specific research, several new treatment strategies such as immune checkpoint inhibitors used in combination PARP inhibitors and other emerging vaccines, including Sipuleucel‐T, have demonstrated some proven efficacy. Conclusion Genomic profiling to integrate clinical and genomic data for diagnosis, prognosis, and treatment will allow physicians to plan a “Precision Medicine” approach to AA men. There is a pressing need for further research for risk stratification, which may allow early identification of AA men with higher risk disease based on their unique clinical, genomic, and immunological profiles, which can then be mapped to appropriate clinical trials. Treatment options are outlined, with a concise description of recent work in AA specific populations, detailing several targeted therapies, including immunotherapy. Also, a summary of current clinical trials involving AA men is presented, and it is important that policies are adopted to ensure that AA men are actively recruited. Although it is encouraging that many of these explore the lifestyle and educational initiatives and therapeutic interventions, there is much still work to be done to reduce incidence and mortality in AA men and equalize current racial disparities.
