Abstract
Epidemiological data highlight prostate cancer as a significant global health issue, with high incidence and substantial impact on patients' quality of life. The prevalence of this disease is associated with various factors, including age, heredity, and race. Recent research in prostate cancer genetics has identified several genetic variants that may be associated with an increased risk of developing the disease. However, despite the significance of these findings, genetic markers for prostate cancer are not currently utilized in clinical practice as reliable indicators of the disease. In addition to genetics, epigenetic alterations also play a crucial role in prostate cancer development. Aberrant DNA methylation, changes in chromatin structure, and microRNA (miRNA) expression are major epigenetic events that influence oncogenesis. Existing markers for prostate cancer, such as prostate-specific antigen (PSA), have limitations in terms of sensitivity and specificity. The cost of testing, follow-up procedures, and treatment for false-positive results and overdiagnosis contributes to the overall healthcare expenditure. Improving the effectiveness of prostate cancer diagnosis and prognosis requires either narrowing the risk group by identifying new genetic factors or enhancing the sensitivity and specificity of existing markers. Immunological biomarkers (both circulating and intra-tumoral), including markers of immune response and immune dysfunction, represent a potentially useful area of research for enhancing the diagnosis and prognosis of prostate cancer. Our review emphasizes the need for developing novel immunological biomarkers to improve the diagnosis, prognosis, and management of prostate cancer. We highlight the most recent achievements in the identification of biomarkers provided by circulating monocytes and tumor-associated macrophages (TAMs). We highlight that monocyte-derived and TAM-derived biomarkers can enable to establish the missing links between genetic predisposition, hormonal metabolism and immune responses in prostate cancer.

Low risk is low risk, regardless of race or ethnicity: Outcomes of prostate cancer active surveillance and factors associated with reclassification in a racially diverse cohort. Urol Oncol 2023; 41:204.e7-204.e15. [PMID: 36740489 DOI: 10.1016/j.urolonc.2023.01.007] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/26/2022] [Revised: 12/04/2022] [Accepted: 01/09/2023] [Indexed: 02/05/2023]
Abstract
INTRODUCTION Active surveillance (AS) is the standard for very low- and low-risk prostate cancer. Although risk factors for pathologic reclassification while on AS have been identified, results are mixed for non-Hispanic Black (NHB) and Hispanic ethnicity. We aim to further explore how race and ethnicity may be affecting AS participation and outcomes in a primarily urban, diverse, and vulnerable population. MATERIALS AND METHODS Patients eligible for AS from 2005-2020 were reviewed. Demographics, race/ethnicity, prostate specific antigen (PSA), prostate volume, and pathologic characteristics were analyzed between patients enrolled in AS and those that underwent immediate therapy. Kaplan-Meier survival analysis was used to compare biochemical recurrence (BCR) rates. Cox proportional hazards models were used to develop prediction models for clinical reclassification. RESULTS A total of 471 men were eligible for AS. Of those, 188 (39.9%) enrolled in AS while 283 (60.1%) underwent immediate radical therapy. No significant differences were found in racial/ethnic composition between the AS and immediate treatment groups. In our AS cohort, 79 (42.0%) experienced clinical reclassification and underwent deferred treatment. BCR rates were similar between treatment groups. Race/ethnicity were not found to be predictors of clinical reclassification, while metrics at diagnostic biopsy such as elevated PSA, higher PSA density, and lower prostate volume increased reclassification odds. CONCLUSIONS In our diverse population, NHB race and Hispanic ethnicity were not significant predictors of adverse reclassification while on AS. Our findings support utilizing other metrics taken at initial biopsy to identify high-risk patients such as PSA, prostate volume, and PSA density.

Abstract
IMPORTANCE As the field of medicine strives for equity in care, research showing the association of social determinants of health (SDOH) with poorer health care outcomes is needed to better inform quality improvement strategies. OBJECTIVE To evaluate the association of SDOH with prostate cancer-specific mortality (PCSM) and overall survival (OS) among Black and White patients with prostate cancer. DATA SOURCES A MEDLINE search was performed of prostate cancer comparative effectiveness research from January 1, 1960, to June 5, 2020. STUDY SELECTION Two authors independently selected studies conducted among patients within the United States and performed comparative outcome analysis between Black and White patients. Studies were required to report time-to-event outcomes. A total of 251 studies were identified for review. DATA EXTRACTION AND SYNTHESIS Three authors independently screened and extracted data. End point meta-analyses were performed using both fixed-effects and random-effects models. The Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) reporting guideline was followed, and 2 authors independently reviewed all steps. All conflicts were resolved by consensus. MAIN OUTCOMES AND MEASURES The primary outcome was PCSM, and the secondary outcome was OS. With the US Department of Health and Human Services Healthy People 2030 initiative, an SDOH scoring system was incorporated to evaluate the association of SDOH with the predefined end points. The covariables included in the scoring system were age, comorbidities, insurance status, income status, extent of disease, geography, standardized treatment, and equitable and harmonized insurance benefits. The scoring system was discretized into 3 categories: high (≥10 points), intermediate (5-9 points), and low (<5 points). RESULTS The 47 studies identified comprised 1 019 908 patients (176 028 Black men and 843 880 White men; median age, 66.4 years [IQR, 64.8-69.0 years]). The median follow-up was 66.0 months (IQR, 41.5-91.4 months). Pooled estimates found no statistically significant difference in PCSM for Black patients compared with White patients (hazard ratio [HR], 1.08 [95% CI, 0.99-1.19]; P = .08); results were similar for OS (HR, 1.01 [95% CI, 0.95-1.07]; P = .68). There was a significant race-SDOH interaction for both PCSM (regression coefficient, -0.041 [95% CI, -0.059 to 0.023]; P < .001) and OS (meta-regression coefficient, -0.017 [95% CI, -0.033 to -0.002]; P = .03). In studies with minimal accounting for SDOH (<5-point score), Black patients had significantly higher PCSM compared with White patients (HR, 1.29; 95% CI, 1.17-1.41; P < .001). In studies with greater accounting for SDOH variables (≥10-point score), PCSM was significantly lower among Black patients compared with White patients (HR, 0.86; 95% CI, 0.77-0.96; P = .02). CONCLUSIONS AND RELEVANCE The findings of this meta-analysis suggest that there is a significant interaction between race and SDOH with respect to PCSM and OS among men with prostate cancer. Incorporating SDOH variables into data collection and analyses are vital to developing strategies for achieving equity.

Abstract
Despite notable screening, diagnostic, and therapeutic advances, disparities in prostate cancer incidence and outcomes remain prevalent. Although commonly discussed in the context of men of African descent, disparities also exist based on socioeconomic level, education level, and geographic location. The factors in these disparities span systemic access issues affecting availability of care, provider awareness, and personal patient views and mistrust. In this review, we will discuss common themes that patients have noted as impediments to care. We will review how equitable access to care has helped improve outcomes among many different groups of patients, including those with local disease and those with metastatic castration-resistant prostate cancer. Even with more advanced presentation, challenges with recommended screening, and lower rates of genomic testing and trial inclusion, Black populations have benefited greatly from various modalities of therapy, achieving comparable and at times superior outcomes with certain types of immunotherapy, chemotherapy, androgen receptor-based inhibitors, and radiopharmaceuticals in advanced disease. We will also briefly discuss access to genomic testing and differences in patterns of gene expression among Black patients and other groups that are traditionally underrepresented in trials and genomic cohort studies. We propose several strategies on behalf of providers and institutions to help promote more equitable care access environments and continued decreases in prostate cancer disparities across many subgroups.

Abstract
Prostate cancer remains the leading diagnosed cancer and the second leading cause of death among American men. Despite improvements in screening modalities, diagnostics, and treatment, disparities exist among Black men in this country. The primary objective of this systematic review is to describe the reported disparities in screening, diagnostics, and treatments as well as efforts to alleviate these disparities through community and educational outreach efforts. Critical review took place of retrospective, prospective, and socially descriptive data of English language publications in the PubMed database. Despite more advanced presentation, lower rates of screening and diagnostic procedures, and low rates of trial inclusion, subanalyses have shown that various modalities of therapy are quite effective in Black populations. Moreover, patients treated on prospective clinical trials and within equal-access care environments have shown similar outcomes regardless of race. Additional prospective studies and enhanced participation in screening, diagnostic and genetic testing, clinical trials, and community-based educational endeavors are important to ensure equitable progress in prostate cancer for all patients. IMPLICATIONS FOR PRACTICE: Notable progress has been made with therapeutic advances for prostate cancer, but racial disparities continue to exist. Differing rates in screening and utility in diagnostic procedures play a role in these disparities. Black patients often present with more advanced disease, higher prostate-specific antigen, and other adverse factors, but outcomes can be attenuated in trials or in equal-access care environments. Recent data have shown that multiple modalities of therapy are quite effective in Black populations. Novel and bold hypotheses to increase inclusion in clinical trial, enhance decentralized trial efforts, and enact successful models of patient navigation and community partnership are vital to ensure continued progress in prostate cancer disparities.

Abstract
Active surveillance (AS) is a treatment modality for prostate cancer that aims to simultaneously avoid overtreatment and allow for the timely intervention of localized disease. AS has become the de facto standard of care for most men with low-risk prostate cancer. However, few African American (AA) men were included in the prospective observational cohorts that resulted in a paradigm shift in treatment recommendations from active intervention toward AS. It has been established that AA men have an increased prostate cancer incidence, higher baseline prostate-specific antigen (PSA) values, more aggressive prostate cancer features, greater frequency of biochemical recurrence after treatment, and higher overall cancer-specific mortality compared to their Caucasian counterparts. As such, this has given many physicians pause before initiating AS for AA patients. In the following manuscript, we will review the available literature regarding AS, with a particular focus on AA men. The preponderance of evidence demonstrates that AS is as viable a management method for AA with low-risk prostate cancer as it is with other racial groups.

Abstract
IMPORTANCE There is extensive evidence suggesting that black men with localized prostate cancer (PCa) have worse cancer-specific mortality compared with their non-Hispanic white counterparts. OBJECTIVE To evaluate racial disparities in the use, quality of care, and outcomes of radical prostatectomy (RP) in elderly men (≥ 65 years) with nonmetastatic PCa. DESIGN, SETTING, AND PARTICIPANTS This retrospective analysis of outcomes stratified according to race (black vs non-Hispanic white) included 2020 elderly black patients (7.6%) and 24,462 elderly non-Hispanic white patients (92.4%) with localized PCa who underwent RP within the first year of PCa diagnosis in the Surveillance, Epidemiology, and End Results (SEER)-Medicare database between 1992 and 2009. The study was performed in 2014. MAIN OUTCOMES AND MEASURES Process of care (ie, time to treatment, lymph node dissection), as well as outcome measures (ie, complications, emergency department visits, readmissions, PCa-specific and all-cause mortality, costs) were evaluated using Cox proportional hazards regression. Multivariable conditional logistic regression and quantile regression were used to study the association of racial disparities with process of care and outcome measures. RESULTS The proportion of black patients with localized prostate cancer who underwent RP within 90 days was 59.4% vs 69.5% of non-Hispanic white patients (P < 001). In quantile regression of the top 50% of patients, blacks had a 7-day treatment delay compared with non-Hispanic whites. (P < 001). Black patients were less likely to undergo lymph node dissection (odds ratio [OR], 0.76 [95% CI, 0.66-0.80]; P < .001) but had higher odds of postoperative visits to the emergency department (within 30 days: OR, 1.48 [95% CI, 1.18-1.86]); after 30 days or more (OR, 1.45 [95% CI, 1.19-1.76]) and readmissions (within 30 days: OR, 1.28 [95% CI, 1.02-1.61]); ≥ 30 days (OR, 1.27 [95% CI, 1.07-1.51]) compared with non-Hispanic whites. The surgical treatment of black patients was associated with a higher incremental annual cost (the top 50% of blacks spent $1185.50 (95% CI , $804.85-1 $1566.10; P < .001) more than the top 50% of non-Hispanic whites). There was no difference in PCa-specific mortality (P = .16) or all-cause mortality (P = .64) between black and non-Hispanic white men. CONCLUSIONS AND RELEVANCE Blacks treated with RP for localized PCa are more likely to experience adverse events and incur higher costs compared with non-Hispanic white men; however, this does not translate into a difference in PCa-specific or all-cause mortality.

Abstract
Active surveillance (AS) is a treatment strategy for prostate cancer (PCa) whereby patients diagnosed with PCa undergo ongoing characterization of their disease with the intent of avoiding radical treatment. Previously, AS has been demonstrated to be a reasonable option for men with low-risk PCa, but existing cohorts largely consist of Caucasian Americans. Because African Americans have a greater incidence, more aggressive, and potentially more lethal PCa than Caucasian Americans, it is unclear if AS is appropriate for African Americans. We performed a review of the available literature on AS with a focus on African Americans.

Abstract
Universal screening for prostate cancer (Pca) using prostate-specific antigen-based testing is not recommended, as the potential harms of screening (overdiagnosis and overtreatment) outweigh potential benefits. The case for Pca screening requires a paradigm shift, which emphasizes the risks of screening over the risks of undetected cancer. Physicians are encouraged to use shared decision making with patients who express an interest in Pca screening, taking into account both the patient's screening preferences and individual risk profile. New models of care informed by the Patient Protection and Affordable Care Act are intended to assist clinicians in providing recommended preventive services.

Cost-effectiveness of magnetic resonance (MR) imaging and MR-guided targeted biopsy versus systematic transrectal ultrasound-guided biopsy in diagnosing prostate cancer: a modelling study from a health care perspective. Eur Urol 2013; 66:430-6. [PMID: 24377803 DOI: 10.1016/j.eururo.2013.12.012] [Citation(s) in RCA: 157] [Impact Index Per Article: 14.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/10/2013] [Accepted: 12/09/2013] [Indexed: 11/29/2022]
Abstract
BACKGROUND The current diagnostic strategy using transrectal ultrasound-guided biopsy (TRUSGB) raises concerns regarding overdiagnosis and overtreatment of prostate cancer (PCa). Interest in integrating multiparametric magnetic resonance imaging (MRI) and magnetic resonance-guided biopsy (MRGB) into the diagnostic pathway to reduce overdiagnosis and improve grading is gaining ground, but it remains uncertain whether this image-based strategy is cost-effective. OBJECTIVE To determine the cost-effectiveness of multiparametric MRI and MRGB compared with TRUSGB. DESIGN, SETTING, AND PARTICIPANTS A combined decision tree and Markov model for men with elevated prostate-specific antigen (>4 ng/ml) was developed. Input data were derived from systematic literature searches, meta-analyses, and expert opinion. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS Quality-adjusted life years (QALYs) and health care costs of both strategies were modelled over 10 yr after initial suspicion of PCa. Probabilistic and threshold analyses were performed to assess uncertainty. RESULTS AND LIMITATIONS Despite uncertainty around the presented cost-effectiveness estimates, our results suggest that the MRI strategy is cost-effective compared with the standard of care. Expected costs per patient were € 2423 for the MRI strategy and € 2392 for the TRUSGB strategy. Corresponding QALYs were higher for the MRI strategy (7.00 versus 6.90), resulting in an incremental cost-effectiveness ratio of € 323 per QALY. Threshold analysis revealed that MRI is cost-effective when sensitivity of MRGB is ≥ 20%. The probability that the MRI strategy is cost-effective is around 80% at willingness to pay thresholds higher than € 2000 per QALY. CONCLUSIONS Total costs of the MRI strategy are almost equal with the standard of care, while reduction of overdiagnosis and overtreatment with the MRI strategy leads to an improvement in quality of life. PATIENT SUMMARY We compared costs and quality of life (QoL) of the standard "blind" diagnostic technique with an image-based technique for men with suspicion of prostate cancer. Our results suggest that costs were comparable, with higher QoL for the image-based technique.

Abstract
Cancer registry data often lack complete chemotherapy and radiation therapy information. To conduct treatment disparity surveillance, we linked 2005–2009 Nebraska Cancer Registry data with Nebraska hospital discharge data. Due to the high quality of both datasets and the proposed linkage procedure, we had a linkage rate of 97 percent. We demonstrate the utilization of the linked dataset in case finding, treatment update, and treatment surveillance. The results show that the linked dataset is likely to identify up to 5 percent of potential missed cases. We investigated the use of radiation therapy in treating colorectal and breast cancers as case-finding examples. The linked dataset found 12 percent and 14 percent more treatment cases for colorectal and breast cancer patients, respectively.

Abstract
OBJECTIVE To describe ethnic disparities in the risk of spontaneous preterm birth and related adverse neonatal outcome. DESIGN Nationwide prospective cohort study. SETTING The Netherlands, 1999-2007. POPULATION Nine hundred and sixty-nine thousand, four hundred and ninety-one singleton pregnancies with a spontaneous onset of labor. METHODS We investigated ethnic disparities in perinatal outcome for European white, African, South-Asian, Mediterranean and East-Asian women. We performed multivariate logistic regression analyses to calculate the adjusted odds ratio (aOR) and confidence intervals (CIs) of spontaneous preterm birth and the risk of subsequent neonatal morbidity and mortality. MAIN OUTCOME MEASURES The primary outcome measure was spontaneous preterm birth before 37 completed weeks of gestation. Secondarily, we investigated subsequent adverse neonatal outcome, which was a composite outcome of intraventricular hemorrhage, bronchopulmonary dysplasia, infant respiratory distress syndrome, neonatal sepsis or neonatal mortality within 28 days after birth. RESULTS Compared with European whites, the aOR of delivering preterm was 1.33 (95% CI 1.26-1.41) for African women, 1.58 (95% CI 1.47-1.69) for South-Asians, 0.88 (95% CI 0.84-0.91) for Mediterraneans and 1.04 (95% CI 0.98-1.11) for East-Asians. Subsequent odds of adverse neonatal outcome were significantly lower for African (aOR 0.51; 95% CI 0.41-0.64) and Mediterranean women (aOR 0.86; 95% CI 0.75-0.99) when compared with European whites. CONCLUSIONS African and South-Asian women are at higher risk for preterm birth than European white women. However, the harmful effect of preterm birth on neonatal outcome is less severe for these women.

Abstract
BACKGROUND Active surveillance (AS) is increasingly utilized in low-risk prostate cancer (PC) patients. Although black race has traditionally been associated with adverse PC characteristics, its prognostic value for patients managed with AS is unclear. METHODS A retrospective review identified 145 patients managed with AS at the Duke Prostate Center from January 2005 to September 2011. Race was patient-reported and categorized as black, white or other. Inclusion criteria included PSA <10 ng ml(-1), Gleason sum ≤ 6, and ≤ 33% of cores with cancer on diagnostic biopsy. The primary outcome was discontinuation of AS for treatment due to PC progression. In men who proceeded to treatment after AS, the trigger for treatment, follow-up PSA and biopsy characteristics were analyzed. Time to treatment was analyzed with univariable and multivariable Cox proportional hazards models and also stratified by race. RESULTS In our AS cohort, 105 (72%) were white, 32 (22%) black and 8 (6%) another race. Median follow-up was 23.0 months, during which 23% percent of men proceeded to treatment. The demographic, clinical and follow-up characteristics did not differ by race. There was a trend toward more uninsured black men (15.6% black, 3.8% white, 0% other, P = 0.06). Black race was associated with treatment (hazard ratio (HR) 2.93, P = 0.01) as compared with white. When the analysis was adjusted for socioeconomic and clinical parameters at the time of PC diagnosis, black race remained the sole predictor of treatment (HR 3.08, P = 0.01). Among men undergoing treatment, the trigger was less often patient driven in black men (8 black, 33 white, 67% other, P = 0.05). CONCLUSIONS Black race was associated with discontinuation of AS for treatment. This relationship persisted when adjusted for socioeconomic and clinical parameters.
