Abstract
Prostate cancer is the second most commonly diagnosed non-skin malignancy and the second leading cause of cancer death among men in the USA. However, the mortality rate of African American men aged 40-60 years is almost 2.5-fold greater than that of European American men. Despite screening and diagnostic and therapeutic advances, disparities in prostate cancer incidence and outcomes remain prevalent. The reasons that lead to this disparity in outcomes are complex and multifactorial. Established non-modifiable risk factors such as age and genetic predisposition contribute to this disparity; however, evidence suggests that modifiable risk factors (including social determinants of health, diet, steroid hormones, environment and lack of diversity in enrolment in clinical trials) are prominent contributing factors to the racial disparities observed. Disparities involved in the diagnosis, treatment and survival of African American men with prostate cancer have also been correlated with low socioeconomic status, education and lack of access to health care. The effects and complex interactions of prostate cancer modifiable risk factors are important considerations for mitigating the incidence and outcomes of this disease in African American men.

Abstract
BACKGROUND In the United States, Black men are at highest risk for being diagnosed with and dying from prostate cancer. Given this disparity, we examined relevant data to establish clinical prostate-specific antigen (PSA) screening guidelines for Black men in the United States. METHODS A comprehensive literature search identified 1848 unique publications for screening. Of those screened, 287 studies were selected for full-text review, and 264 were considered relevant and form the basis for these guidelines. The numbers were reported according to PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. RESULTS Three randomized controlled trials provided Level 1 evidence that regular PSA screening of men 50 to 74 years of age of average risk reduced metastasis and prostate cancer death at 16 to 22 years of follow-up. The best available evidence specifically for Black men comes from observational and modeling studies that consider age to obtain a baseline PSA, frequency of testing, and age when screening should end. Cohort studies suggest that discussions about baseline PSA testing between Black men and their clinicians should begin in the early 40s, and data from modeling studies indicate prostate cancer develops 3 to 9 years earlier in Black men compared with non-Black men. Lowering the age for baseline PSA testing to 40 to 45 years of age from 50 to 55 years of age, followed by regular screening until 70 years of age (informed by PSA values and health factors), could reduce prostate cancer mortality in Black men (approximately 30% relative risk reduction) without substantially increasing overdiagnosis. CONCLUSIONS These guidelines recommend that Black men should obtain information about PSA screening for prostate cancer. Among Black men who elect screening, baseline PSA testing should occur between ages 40 and 45. Depending on PSA value and health status, annual screening should be strongly considered.

Abstract
Since the widespread adoption of prostate-specific antigen-based screening for prostate cancer, the prevalence of Grade Group 1 (GG1) prostate cancer has risen. Historically, these patients were subjected to overtreatment of this otherwise indolent disease process, leading to significant quality-of-life detriments. Active surveillance as a primary management strategy has allowed for a focus on early detection while minimising morbidity from unnecessary intervention. Here we provide a comprehensive overview of the characteristics of GG1 prostatic adenocarcinoma, including its histological features, genomic differentiators, clinical progression, and implications for treatment guidelines, all supporting the movement to reclassify GG1 disease as a non-cancerous entity.

Abstract
ABSTRACT Prostate cancer (PCa) in African American men is one of the most common cancers with a great disparity in outcomes. The higher incidence and tendency to present with more advanced disease have prompted investigators to postulate that this is a problem of innate biology. However, unequal access to health care and poorer quality of care raise questions about the relative importance of genetics versus social/health injustice. Although race is inconsistent with global human genetic diversity, we need to understand the sociocultural reality that race and racism impact biology. Genetic studies reveal enrichment of PCa risk alleles in populations of West African descent and population-level differences in tumor immunology. Structural racism may explain some of the differences previously reported in PCa clinical outcomes; fortunately, there is high-level evidence that when care is comparable, outcomes are comparable.

Abstract
PURPOSE OF REVIEW Disparities in prostate cancer care and outcomes have been well recognized for decades. The purpose of this review is to methodically highlight known racial disparities in the care of prostate cancer patients, and in doing so, recognize potential strategies for overcoming these disparities moving forward. RECENT FINDINGS Over the past few years, there has been a growing recognition and push towards addressing disparities in cancer care. This has led to improvements in care delivery trends and a narrowing of racial outcome disparities, but as we highlight in the following review, there is more to be addressed before we can fully close the gap in prostate cancer care delivery. While disparities in prostate cancer care are well recognized in the literature, they are not insurmountable, and progress has been made in identifying areas for improvement and potential strategies for closing the care gap.

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
Androgen deprivation therapy is the cornerstone of prostate cancer therapy. Recent studies have revealed an association between androgen deprivation therapy and cardiovascular adverse effects such as myocardial infarction and stroke. This review summarizes the available research on the cardiovascular risk of men using androgen deprivation therapy. We also discuss racial disparities surrounding both prostate cancer and cardiovascular disease, emphasizing the importance of biological/molecular and socioeconomic factors in assessing baseline risk in patients beginning androgen ablation. Based on the literature, we provide recommendations for monitoring patients who are at high risk for a cardiovascular adverse event while being treated on androgen deprivation therapy. This review aims to present the current research on androgen deprivation therapy and cardiovascular toxicity with an emphasis on racial disparities and provides a framework for clinicians to decrease the cardiovascular morbidity in men that are being treated with hormone therapy.

Abstract
BACKGROUND Genetic scores may provide an objective measure of prostate cancer risk and thus inform screening decisions. We evaluated whether a polygenic hazard score based on 290 genetic variants (PHS290) is associated with prostate cancer risk in a diverse population, including Black men, who have higher average risk of prostate cancer death but are often treated as a homogeneously high-risk group. METHODS This was a retrospective analysis of the Million Veteran Program, a national, population-based cohort study of US military veterans conducted 2011-2021. Cox proportional hazards analyses tested for association of genetic and other risk factors (including self-reported race and ethnicity and family history) with age at death from prostate cancer, age at diagnosis of metastatic (nodal or distant) prostate cancer, and age at diagnosis of any prostate cancer. RESULTS A total of 590 750 male participants were included. Median age at last follow-up was 69 years. PHS290 was associated with fatal prostate cancer in the full cohort and for each racial and ethnic group (P < .001). Comparing men in the highest 20% of PHS290 with those in the lowest 20% (based on percentiles from an independent training cohort), the hazard ratio for fatal prostate cancer was 4.42 (95% confidence interval = 3.91 to 5.02). When accounting for guideline-recommended risk factors (family history, race, and ethnicity), PHS290 remained a strong independent predictor of any, metastatic, and fatal prostate cancer. CONCLUSIONS PHS290 stratified US veterans of diverse ancestry for lifetime risk of prostate cancer, including metastatic and fatal cancer. Predicting genetic risk of lethal prostate cancer with PHS290 might inform individualized decisions about prostate cancer screening.

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.

Esdaille AR, Ibilibor C, Holmes A, Palmer NR, Murphy AB. 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.

J Geriatr Oncol 2022; 13:200-206. [PMID: 34563484 PMCID: PMC9991462 DOI: 10.1016/j.jgo.2021.09.012] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/24/2021] [Revised: 08/02/2021] [Accepted: 09/15/2021] [Indexed: 01/22/2023]
Abstract
OBJECTIVES Black men are more likely to die of prostate cancer (PCa) than White men. Whether this difference is driven by biological versus sociodemographic and access to care differences is actively investigated. However, studies that have highlighted racial disparities in PCa outcomes have been poorly represented by elderly men, a notoriously undertreated group. Herein, we evaluated use of curative treatment between Black and White elderly men with aggressive PCa in a large US database. METHODS Men ≥80 years diagnosed with National Comprehensive Cancer Network-defined high risk PCa between 2004 and 2016 were analyzed from the National Cancer Database. Multivariable logistic regression was used to model the effect of race and sociodemographic factors on receipt of definitive therapy (surgery or radiation +/- androgen deprivation therapy [ADT]) versus non-definitive therapy (ADT alone or observation) in inverse probability weighted groups matched for stage, prostate-specific antigen, and Gleason score. RESULTS Between 2004 and 2016, utilization of definitive therapy with either surgery or radiation therapy increased in both White and Black men in the United States. However, we found that Black men compared with White men were significantly less likely to receive definitive therapy (OR 0.71, 95% CI 0.64-0.79, p < .001). Using multivariable modeling, effect size diminished after adjusting for sociodemographic variables. Notably, there is evidence of the racial disparity narrowing over time. CONCLUSIONS These findings highlight striking but improving racial disparities in elderly men with high risk PCa in the US, an overall undertreated population.

Abstract
Racial differences of prostate cancer incidence and mortality among Asian, Black, and Caucasian men have been known, however, comprehensive update of this topic is not yet reported. In the present review, an overview of the racial differences in prostate cancer characteristics and cancer-specific mortality is collected and reviewed. Regarding racial differences of incidence and mortality, surprising differences in the incidence of prostate cancer are seen among different populations around the world, with some countries having rates that are 60 to 100 times higher than others. African-American men have a higher incidence of prostate cancer, higher prostate cancer mortality, and are diagnosed with prostate cancer at a younger age than Caucasian American men. Furthermore, race is gaining attention as an important factor to consider for planning active surveillance for localized prostate cancer, especially among African-Americans. In addition, the causes of these differences are being elucidated by genomic profiling. Determinants of racial disparities are multifactorial, including socioeconomic and biologic factors. Although race-specific differences in prostate cancer survival estimates appear to be narrowing over time, there is an ongoing need to continue to understand and mitigate racial factors associated with disparities in health care outcomes.

Abstract
The role of molecular imaging in initial evaluation of men with presumed or established diagnosis of prostate cancer and work up of biochemical recurrence and metastatic disease is rapidly evolving due to superior diagnostic performance compared to anatomic imaging. However, variable tumor biology and expression of transmembrane proteins or metabolic alterations poses a challenge. We review the evidence and controversies with emphasis on emerging PET radiopharmaceuticals and experience on clinical utility of PET/CT and PET/MRI in diagnosis and management of prostate cancer.

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 Black men in the United States have markedly higher rates of prostate cancer than the general population. National guidelines for prostate-specific antigen (PSA) screening do not provide clear guidance for this high-risk population. The purpose of this study is to estimate the benefit and harm of intensified PSA screening in Black men. METHODS Two microsimulation models of prostate cancer calibrated to incidence from the Surveillance, Epidemiology, and End Results program among Black men project the impact of different screening strategies (varying screening intervals, starting and stopping ages, and biopsy utilization following an abnormal PSA) on disease-specific mortality and overdiagnosis. Each strategy induces a mean lead time (MLT) for detected cases. A longer MLT reduces mortality according to estimates combining the US and European prostate cancer screening trials but increases overdiagnosis. RESULTS Under historical population screening, Black men had similar MLT to men of all races, and similar mortality reduction (range between models = 21-24% vs. 20-24%) but a higher frequency of overdiagnosis (75-86 vs. 58-60 per 1000 men). Screening Black men aged 40-84 years annually would increase both mortality reduction (29-31%) and overdiagnosis (112-129 per 1000). Restricting screening to age 45-69 years would still achieve substantial mortality reduction (26-29%) with lower overdiagnosis (51-61 per 1000). Increasing biopsy utilization to 100% of abnormal tests would further reduce mortality but substantially increase overdiagnosis. CONCLUSIONS Annual screening in Black men is expected to reduce mortality more than that estimated under historical screening. Limiting screening to men below 70 years is expected to help to reduce overdiagnosis.

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
There is a chaotic scenario that exists in the field of prostate cancer (PCa) screening. To balance goals, such as decreasing mortality, avoiding unnecessary procedures, and decreasing the cost of medical care, the pendulum seems to have swung to the side of more restricted screening. The decrease in PCa screening has led to a slowly creeping decline in the favourable outcomes that existed among patients with PCa. If a potential patient or a family member is trying to get clear guidance about PCa screening by searching the internet, they will end up confused by several recommendations from many organisations. It is even more challenging to obtain any clarity about PCa screening for special populations, such as those with a family history of PCa, those of African descent/African Americans, and the elderly. The advent of genomic medicine and precision medicine is an opportunity to identify those at a very high risk of developing aggressive PCa, so that PCa screening can be more actively undertaken among them. In this paper, the authors review the current recommendations by different entities and summarise emerging molecular markers that may help bring clarity to PCa screening. The authors predict that concrete, consensual guidelines will emerge in less than one decade. Meanwhile, this article suggests intermediary steps that will help save lives from PCa mortality, especially for under-represented populations. This paper is a catalyst to stimulate further discussion and serves as a guide to noncancer-specialists for the near future as precision medicine progresses to better understand risk–benefit and cost–benefit ratios in PCa screening.

Abstract
Importance To be effective in reducing deaths from lung cancer among high-risk current and former smokers, screening with low-dose computed tomography must be performed periodically. Objective To examine lung cancer screening (LCS) adherence rates reported in the US, patient characteristics associated with adherence, and diagnostic testing rates after screening. Data Sources Five electronic databases (MEDLINE, Embase, Scopus, CINAHL, and Web of Science) were searched for articles published in the English language from January 1, 2011, through February 28, 2020. Study Selection Two reviewers independently selected prospective and retrospective cohort studies from 95 potentially relevant studies reporting patient LCS adherence. Data Extraction and Synthesis Quality appraisal and data extraction were performed independently by 2 reviewers using the Newcastle-Ottawa Scale for quality assessment. A random-effects model meta-analysis was conducted when at least 2 studies reported on the same outcome. Reporting followed the Preferred Reporting Items for Systematic Review and Meta-analyses (PRISMA) guideline. Main Outcomes and Measures The primary outcome was LCS adherence after a baseline screening. Secondary measures were the patient characteristics associated with adherence and the rate of diagnostic testing after screening. Results Fifteen studies with a total of 16 863 individuals were included in this systematic review and meta-analysis. The pooled LCS adherence rate across all follow-up periods (range, 12-36 months) was 55% (95% CI, 44%-66%). Regarding patient characteristics associated with adherence rates, current smokers were less likely to adhere to LCS than former smokers (odds ratio [OR], 0.70; 95% CI, 0.62-0.80); White patients were more likely to adhere to LCS than patients of races other than White (OR, 2.0; 95% CI, 1.6-2.6); people 65 to 73 years of age were more likely to adhere to LCS than people 50 to 64 years of age (OR, 1.4; 95% CI, 1.0-1.9); and completion of 4 or more years of college was also associated with increased adherence compared with people not completing college (OR, 1.5; 95% CI, 1.1-2.1). Evidence was insufficient to evaluate diagnostic testing rates after abnormal screening scan results. The main source of variation was attributable to the eligibility criteria for screening used across studies. Conclusions and Relevance In this study, the pooled LCS adherence rate after a baseline screening was far lower than those observed in large randomized clinical trials of screening. Interventions to promote adherence to screening should prioritize current smokers and smokers from minority populations.

Lack of Racial Survival Differences in Metastatic Prostate Cancer in National Cancer Data Base (NCDB): A Different Finding Compared to Non-metastatic Disease. Front Oncol 2020; 10:533070. [PMID: 33072567 PMCID: PMC7531281 DOI: 10.3389/fonc.2020.533070] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/06/2020] [Accepted: 08/17/2020] [Indexed: 12/24/2022] Open
Abstract
Background: Inconsistent findings have been reported in the literature regarding racial differences in survival outcomes between African American and white patients with metastatic prostate cancer (mPCa). The current study utilized a national database to determine whether racial differences exist among the target population to address this inconsistency. Methods: This study retrospectively reviewed prostate cancer (PCa) patient data (N = 1,319,225) from the National Cancer Database (NCDB). The data were divided into three groupings based on the metastatic status: (1) no metastasis (N = 318,291), (2) bone metastasis (N = 29,639), and (3) metastases to locations other than bone, such as brain, liver, or lung (N = 952). Survival probabilities of African American and white PCa patients with bone metastasis were examined through parametric proportional hazards Weibull models and Bayesian survival analysis. These results were compared to patients with no metastasis or other types of metastases. Results: No statistically supported racial disparities were observed for African American and white men with bone metastasis (p = 0.885). Similarly, there were no racial disparities in survival for those men suffering from other metastases (liver, lung, or brain). However, racial disparities in survival were observed among the two racial groups with non-metastatic PCa (p < 0.001) or when metastasis status was not taken into account (p < 0.001). The Bayesian analysis corroborates the finding. Conclusion: This research supports our previous findings and shows that there are no racial differences in survival outcomes between African American and white patients with mPCa. In contrast, racial disparities in the survival outcome continue to exist among non-metastatic PCa patients. Further research is warranted to explain this difference.

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
INTRODUCTION Prostate-specific antigen (PSA) is the main tool for early detection, risk stratification and monitoring of prostate cancer (PCa). However, there are controversies about the use of PSA as a population screening test because of the high potential for overdiagnosis and overtreatment associated. The net benefit of screening is unclear and according to the available recommendations, it should be offered to well-informed men with an adequate health status and a life-expectancy of at least 10 years or to men at elevated risk of having PCa. In addition, the factors that influence test results are unclear, as is impact of false positive or negative results on patient health.Our objective is to assess the clinical and analytical factors associated with the presence of false positive and false negative results and the diagnostic/therapeutic process followed by these patients. METHODS AND ANALYSIS A prospective observational cohort study will be carried out. We will include a cohort of patients with a positive PSA result (1.081 patients) and a sample of patients with negative results (572 patients); both will be followed for 2 years by reviewing medical records to assess the variables associated with these results, as well as characteristics of patient management after a positive PSA value. We will include those patients with a PSA determination from 2 hospitals in the Valencian Community. Patients who have been previously diagnosed with prostate cancer or who are being followed for previous high PSA values will be excluded. DISCUSSION The study will estimate the frequency of false positive and false negative PSA results in routine clinical practice, and allow us to quantify the potential harm caused.

Abstract
Resumo Disparidades na atenção ao câncer de próstata têm sido reveladas e associadas a fatores sociodemográficos e clínicos, os quais determinam os tempos para diagnóstico e início do tratamento. O objetivo deste artigo é avaliar a associação de variáveis sociodemográficas e clínicas com os tempos para o início do tratamento do câncer de próstata. Estudo de coorte longitudinal prospectivo utilizando dados secundários, cuja população é de homens com câncer de próstata atendidos nos períodos de 2010-2011 e 2013-2014 no Hospital Santa Rita de Cássia, Vitória, Espírito Santo, Brasil. A população do estudo foi de 1.388 homens, do total, os com idade inferior a 70 anos (OR = 1,85; IC = 1,49-2,31), não brancos (OR = 1,30; IC = 1,00-1,70), com menos de oito anos de estudo (OR = 1,52; IC = 1,06-2,17) e encaminhados pelos serviços do Sistema Único de Saúde (OR = 2,52; IC = 1,84-3,46) apresentaram maior risco de atraso no tratamento. Da mesma forma, quanto menor o escore de Gleason (OR = 1,78; IC = 1,37-2,32) e os níveis de Antígeno Prostático Específico (OR = 2,71; IC = 2,07-3,54) maior a probabilidade de atraso para iniciar o tratamento. Portanto, as características sociodemográficas e clínicas exerceram uma forte influência no acesso ao tratamento do câncer de próstata.

Abstract
OBJECTIVES To determine the rate of Gleason Grade Group (GGG) upgrading in African-American (AA) men with a prior diagnosis of low-grade prostate cancer (GGG 1 or GGG 2) on 12-core systematic biopsy (SB) after multiparametric magnetic resonance imaging (mpMRI) and fusion biopsy (FB); and whether AA men who continued active surveillance (AS) after mpMRI and FB fared differently than a predominantly Caucasian (non-AA) population. PATIENTS AND METHODS A database of men who had undergone mpMRI and FB was queried to determine rates of upgrading by FB amongst men deemed to be AS candidates based on SB prior to referral. After FB, Kaplan-Meier curves were generated for AA men and non-AA men who then elected AS. The time to GGG upgrading and time continuing AS were compared using the log-rank test. RESULTS AA men referred with GGG 1 disease on previous SB were upgraded to GGG ≥3 by FB more often than non-AA men, 22.2% vs 12.7% (P = 0.01). A total of 32 AA men and 258 non-AA men then continued AS, with a median (interquartile range) follow-up of 39.19 (24.24-56.41) months. The median time to progression was 59.7 and 60.5 months, respectively (P = 0.26). The median time continuing AS was 61.9 months and not reached, respectively (P = 0.80). CONCLUSIONS AA men were more likely to be upgraded from GGG 1 on SB to GGG ≥3 on initial FB; however, AA and non-AA men on AS subsequently progressed at similar rates following mpMRI and FB. A greater tendency for SB to underestimate tumour grade in AA men may explain prior studies that have shown AA men to be at higher risk of progression during AS.

Abstract
PURPOSE To study regional trends in average years of potential life lost (AYPLL) among Caucasians (CA) and African Americans (AA) with prostate cancer (Pca) who received radical prostatectomy or radiation therapy among four different regions in the US as well as across different tumor grades. Years of potential life lost is defined as the difference between a predetermined end-point age and the age at death for a death that occurred prior to that end age, hence the AYPLL is calculated by dividing the total YPLL by the total number of patients died. METHODS The surveillance epidemiology and end results (SEER) database was used to identify Pca patients who were CA or AA and who have received radical prostatectomy or radiation therapy. Study duration was divided into four decades; 1973-1982 (D1), 1983-1992 (D2), 1993-2002 (D3), 2003-2012 (D4). Examined regions were; North East (NE), North central (NC), South and West. Tumor grade was classified into; well/moderately differentiated (WD/MD) and poorly/undifferentiated (PD/UD) groups. Differences in AYPLL among CA and AA in each of these variables were compared. RESULTS Overall, compared to CA, AA were diagnosed and died earlier from Pca. AA had higher AYPLL to Pca than CA. In both tumor grade groups, progressive increase in AYPLL among AA compared to CA was noted over the last three decades. In the WD/MD group, except for the South region, the highest recorded difference in AYPLL between AA and CA was in D4. In the PD/UD group, a similar difference in AYPLL between AA and CA was noted in all regions. The difference in AYPLL was higher in the PD/UD group than the WD/MD group. CONCLUSIONS Racial disparity between AA and CA existed across the examined regions. It is more pronounced in advanced tumor grades. The differences were more significant in the last decade.

Abstract
OBJECTIVE We examined prostate cancer patients' perceived engagement in treatment decision-making and associated factors by race/ethnicity in a multiethnic sample. METHOD We identified patients through the California Cancer Registry. Patients completed a cross-sectional telephone interview in English, Spanish, Cantonese, or Mandarin. Multivariable logistic regression models, stratified by race/ethnicity, estimated the associations of patient demographic and health status characteristics on (1) doctor asked patient to help decide treatment plan and (2) patient and doctor worked out a treatment plan together. RESULTS We included 855 prostate cancer patients: African American (19%), Asian American (15%), Latino (24%), and White (42%). Asian American patients were less likely than White patients to report that their doctors asked them to help decide a treatment plan (OR = 0.31; 95% CI = 0.18-0.53) and that they worked out a treatment plan with their doctors (OR = 0.54; 95% CI = 0.33-0.90). Language of interview was a significant contributing factor in stratified analysis for both outcomes. CONCLUSION Asian American prostate cancer patients reported less engagement in treatment decision-making, with Chinese language being a significant contributing factor. Future research should identify patient-centered strategies that effectively engage underserved patients and support healthcare providers in shared decision-making with multiethnic and multilingual patients.

Abstract
Prostate cancer (CaP) incidence, morbidity, and mortality rates vary substantially by race and ethnicity, with African American men experiencing among the highest CaP rates in the world. The causes of these disparities are multifactorial and complex, and likely involve differences in access to screening and treatment, exposure to CaP risk factors, variation in genomic susceptibility, and other biological factors. To date, the proportion of CaP that can be explained by environmental exposures is small and differences in the role factors play by race or ethnicity is poorly understood. In the absence of additional data, it is likely that environmental factors do not contribute greatly to CaP disparities. In contrast, CaP has one of the highest heritabilities of all major cancers and many CaP susceptibility genes have been identified. Some CaP loci, including the risk loci found at chromosome 8q24, have consistent effects in all racial/ethnic groups studied to date. However, replication of many susceptibility loci across race or ethnicity remains limited. It is likely that inequities in health care access strongly influences CaP disparities. CaP is a disease with a complex multifactorial etiology, and therefore any approach attempting to address racial/ethnic disparities in CaP must consider the many sources that influence risk, outcomes, and disparities.

Abstract
BACKGROUND Despite disparities in prostate cancer incidence and mortality rates between black and white men, there is still insufficient data available to assess potential differences in the benefits and harms of prostate cancer screening by race. Although the Prostate, Lung, Colorectal, and Ovarian (PLCO) Screening Trial is underpowered to detect a difference by race in prostate-cancer specific mortality, because of the large study size, there are still sufficient numbers to examine secondary screening outcomes. The objective of this analysis is to examine whether differences exist between black and white participants with respect to screening false-positive rates, biopsy follow-up of men with positive screens, tumor characteristics, and overdiagnosis of prostate cancer. METHODS Participants from the PLCO included men aged 55-74 years at baseline. Cancer diagnoses and deaths were identified through study update questionnaires, records of biopsy procedures, and linkage with the National Death Index. Cancer characteristics were obtained by medical abstractors. We used chi-squared tests to assess differences in false-positive rates, biopsy follow-up, and tumor characteristics. We used Cox proportional hazards models to compare incidence and mortality rates adjusting for age and survival rates adjusting for Gleason scores. RESULTS Black men were slightly more likely (14.5%) to have a false-positive PSA test compared to white men (12.4%; P = 0.02) but less likely to have a false-positive digital rectal exam (DRE) (10.9% vs 14.2%, respectively; P < 0.001). Among all men who were screened, black men were significantly more likely to undergo a biopsy than white men (16.5% vs 13.8%, respectively [P = 0.003]) but there was no difference when limited to those with a positive PSA test. Prostate cancer tumors were more likely to be aggressive and to have metastasized in black men compared to white men. Disparities in incidence, mortality, and survival rates were comparable to those seen in population-based data. CONCLUSIONS There was evidence that false-positive test results differed by race and screening test. Consistent with previous studies, cancer outcomes, and tumor characteristics were all more unfavorable in black men.

Abstract
PURPOSE OF REVIEW The purpose of this review is to examine prostate cancer racial disparities specific to the African-American population. RECENT FINDINGS African-American men are more likely to be diagnosed with prostate cancer, present at an earlier age; are more likely to have locally advanced or metastatic disease at diagnosis; and have suboptimal outcomes to standard treatments. Prostate cancer treatment requires a nuanced approach, particularly when applying screening, counseling, and management of African-American men. Oncological as well as functional outcomes may differ and are potentially due to a combination of genetic, molecular, behavioral, and socioeconomic factors.

Abstract
PURPOSE Intensive repeated measures data collection procedures, such as ecological momentary assessment (EMA) and end-of-day (EOD) diaries, are becoming more prominent in pain research. Existing data on the feasibility of such methods is encouraging; however, almost nothing is known about feasibility in clinical populations with significant physical disabilities. Research methodology feasibility is crucial to the inclusion of individuals with physical disability in pain research given the high prevalence and impact of pain in these populations. The aim of this study was to examine study compliance, protocol acceptability, and reactivity of intensive data collection methods in adults with chronic pain and spinal cord injury (SCI). METHODS Secondary analysis of data from a 7-day EMA and EOD diary study in a sample of 131 community dwelling adults with SCI. RESULTS Results showed rates of missing data ranged from 18.4 to 22.8% across measures. Participant compliance was related to time of day/presence of audible prompts, mobility aid use, race, and baseline levels of pain and pain interference, with more missing data at wake and bedtimes/no prompts, and for those who used hand-held mobility devices, identified as black/African American, and/or reported higher baseline pain and pain interference. Participants rated the study methodology as generally highly acceptable and expressed willingness to participate in similar studies of much longer duration. There was no evidence of reactivity, defined as temporal shifts in pain or pain interference ratings. CONCLUSIONS Overall, intensive pain data collection is feasible in persons with SCI with no evidence that the methodology impacts pain intensity or pain interference ratings.

Abstract
Background Treatment variation in prostate cancer is common, and it is driven by clinical and clinician factors, patient preferences, availability of resources, and access to physicians and treating facilities. Most research on treatment disparities in men with prostate cancer has focused on race and socioeconomic factors. However, the geography of disparities — capturing racial and socioeconomic differences based on where patients live — can provide insight into barriers to care and help identify outlier areas in which access to care, health resources, or both are more pronounced. Methods Research regarding treatment patterns and disparities in prostate cancer using the Geographical Information System (GIS) was searched. Studies were limited to English-language articles and research focused on US populations. A total of 43 articles were found; of those, 30 provided information about or used spatial or geographical analyses to assess and describe differences or disparities in prostate cancer and its treatment. Two additional GIS resources were included. Results The research on geographical and spatial determinants of prostate cancer disparities was reviewed. We also examined geographical analyses at the state level, focusing on Florida. Overall, we described a geographical framework to disparities that affect men with prostate cancer and reviewed existing published evidence supporting the interplay of geographical factors and disparities in prostate cancer. Conclusions Disparities in prostate cancer are common and persistent, and notable differences in treatment are observable across racial and socioeconomic strata. Geographical analysis provides additional information about where disparate groups live and also helps to map access to care. This information can be used by public health officials, health-systems administrators, clinicians, and policymakers to better understand and respond to geographical barriers that contribute to disparities in care.

Abstract
Objectives. Although a growing body of evidence demonstrates the public health burden of prostate cancer in SSA, relatively little is known about the underlying factors surrounding the low levels of testing for the disease in the context of this region. Using Namibia Demographic Health Survey dataset (NDHS, 2013), we examined the factors that influence men's decision to screen for prostate cancer in Namibia. Methods. We use complementary log-log regression models to explore the determinants of screening for prostate cancer. We also corrected for the effect of unobserved heterogeneity that may affect screening behaviours at the cluster level. Results. The results show that health insurance coverage (OR = 2.95, p = 0.01) is an important predictor of screening for prostate cancer in Namibia. In addition, higher education and discussing reproductive issues with a health worker (OR = 2.02, p = 0.05) were more likely to screening for prostate cancer. Conclusions. A universal health insurance scheme may be necessary to increase uptake of prostate cancer screening. However it needs to be acknowledged that expanded screening can have negative consequences and any allocation of scarce resources towards screening must be guided by evidence obtained from the local context about the costs and benefits of screening.

Abstract
PURPOSE Gleason 6 (3+3) is the most commonly diagnosed prostate cancer among men with prostate specific antigen screening, the most histologically well differentiated and is associated with the most favorable prognosis. Despite its prevalence, considerable debate exists regarding the genetic features, clinical significance, natural history, metastatic potential and optimal management. MATERIALS AND METHODS Members of the Young Urologic Oncologists in the Society of Urologic Oncology cooperated in a comprehensive search of the peer reviewed English medical literature on Gleason 6 prostate cancer, specifically focusing on the history of the Gleason scoring system, histological features, clinical characteristics, practice patterns and outcomes. RESULTS The Gleason scoring system was devised in the early 1960s, widely adopted by 1987 and revised in 2005 with a more restrictive definition of Gleason 6 disease. There is near consensus that Gleason 6 meets pathological definitions of cancer, but controversy about whether it meets commonly accepted molecular and genetic criteria of cancer. Multiple clinical series suggest that the metastatic potential of contemporary Gleason 6 disease is negligible but not zero. Population based studies in the U.S. suggest that more than 90% of men newly diagnosed with prostate cancer undergo treatment and are exposed to the risk of morbidity for a cancer unlikely to cause symptoms or decrease life expectancy. Efforts have been proposed to minimize the number of men diagnosed with or treated for Gleason 6 prostate cancer. These include modifications to prostate specific antigen based screening strategies such as targeting high risk populations, decreasing the frequency of screening, recommending screening cessation, incorporating remaining life expectancy estimates, using shared decision making and novel biomarkers, and eliminating prostate specific antigen screening entirely. Large nonrandomized and randomized studies have shown that active surveillance is an effective management strategy for men with Gleason 6 disease. Active surveillance dramatically reduces the number of men undergoing treatment without apparent compromise of cancer related outcomes. CONCLUSIONS The definition and clinical relevance of Gleason 6 prostate cancer have changed substantially since its introduction nearly 50 years ago. A high proportion of screen detected cancers are Gleason 6 and the metastatic potential is negligible. Dramatically reducing the diagnosis and treatment of Gleason 6 disease is likely to have a favorable impact on the net benefit of prostate cancer screening.

Variation of Prostate-specific Antigen Value in Men and Risk of High-grade Prostate Cancer: Analysis of the Prostate, Lung, Colorectal, and Ovarian Cancer Screening Trial Study. Urology 2015; 85:1117-1122. [PMID: 25917734 DOI: 10.1016/j.urology.2015.02.013] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/04/2014] [Revised: 01/30/2015] [Accepted: 02/12/2015] [Indexed: 11/22/2022]
Abstract
OBJECTIVE To investigate variations in prostate-specific antigen (PSA) levels among men with an initial normal PSA level in the Prostate, Lung, Colorectal, and Ovarian Cancer Screening Trial study. METHODS Data were extracted from the Prostate, Lung, Colorectal, and Ovarian Cancer Screening Trial study data set on all men in the interventional arm, with 2 tests performed in a period of < 2 years and with an initial result of the first test <4 ng/mL. The range of variation between first and second tests was computed. Risks of cancer stratified on Gleason score were computed using logistic regression. RESULTS A total of 31,286 men had 2 PSA tests within 2 years and with an initial value < 4 ng/mL. From the first to the second test, the median variation of PSA levels was 3.4% (interquartile range, -15% to +26%). The variation in PSA value was not associated with the delay between the first and the second test (P = .36), age (P = .16), body mass index (P = .41), and race (P = .12). A total of 2,781 prostate cancers were diagnosed during follow-up. Adjusting for age and initial PSA level, the risk of prostate cancer increased linearly with increasing PSA level at the second test, with an odds ratio of 1.079 (95% confidence interval, 1.058-1.101) for each percent increase in PSA level. However, the variation in PSA was not associated with a higher Gleason score (P = .95 for level variations in cancer of Gleason score < 7 vs ≥ 7). CONCLUSION Although an increase in PSA level over time is associated with increased risk of prostate cancer, this association is not related to more aggressive tumors.

Impact of Early Diagnosis of Prostate Cancer on Survival Outcomes. Eur Urol Focus 2015; 1:137-146.

Abstract
CONTEXT The relationship between early detection of prostate cancer (PCa) and disease-specific mortality is still the subject of much debate. OBJECTIVE This review describes developments in PCa mortality rates and disease-stage shift on a population level. The main findings from the randomised screening trials are also discussed. Finally, we consider the expected consequences for the individual man interested in screening. EVIDENCE ACQUISITION The PubMed database was searched for trials of screening for PCa from inception through October 11, 2014. Supplementary information was collected by cross-referencing the reference lists. EVIDENCE SYNTHESIS Since the introduction of prostate-specific antigen testing, PCa incidence has risen, and a stage shift towards more favourable disease at diagnosis has been observed. PCa mortality rates are gradually decreasing. Although screening trials show conflicting results, the largest randomised trial of screening for PCa shows a 21% decrease in PCa-specific mortality. After correction for noncompliance and contamination, a risk reduction in PCa-specific mortality of up to 49% has been reported. The main side effect of screening is that some studies have estimated that approximately 50% of detected cases may represent overdiagnosis, which may be reduced by stopping screening in older men and using an individual risk-based approach. CONCLUSIONS To maximise the benefits while minimising the risk of overdiagnosis, future screening should follow an individual risk-based approach. PATIENT SUMMARY On a population level, the introduction of screening for prostate cancer (PCa) is associated with more men diagnosed but with more favourable disease. The largest screening study confirmed the reduction in death due to PCa. Individual risk estimation is important to best balance the benefits and potential harms of early detection.

Abstract
BACKGROUND Racial disparities in cancer survival outcomes have been primarily attributed to underlying biologic mechanisms and the quality of cancer care received. Because prior literature shows little difference exists in the socioeconomic status of non-Hispanic whites and Asian Americans, any difference in cancer survival is less likely to be attributable to inequalities of care. We sought to examine differences in cancer-specific survival between whites and Asian Americans. METHODS The Surveillance, Epidemiology, and End Results Program was used to identify patients with lung (n = 130 852 [16.9%]), breast (n = 313 977 [40.4%]), prostate (n = 166 529 [21.4%]), or colorectal (n = 165 140 [21.3%]) cancer (the three leading causes of cancer-related mortality within each sex) diagnosed between 1991 and 2007. Fine and Gray's competing risks regression compared the cancer-specific mortality (CSM) of eight Asian American groups (Chinese, Filipino, Hawaiian/Pacific Islander, Japanese, Korean, other Asian, South Asian [Indian/Pakistani], and Vietnamese) to non-Hispanic white patients. All P values were two-sided. RESULTS In competing risks regression, the receipt of definitive treatment was an independent predictor of CSM (hazard ratio [HR] = 0.37, 95% confidence interval [CI] = 0.35 to 0.40; HR = 0.55, 95% CI = 0.53 to 0.58; HR = 0.61, 95% CI = 0.60 to 0.62; and HR = 0.27, 95% CI = 0.25 to 0.29) for prostate, breast, lung, and colorectal cancers respectively, all P < .001). In adjusted analyses, most Asian subgroups (except Hawaiians and Koreans) had lower CSM relative to white patients, with hazard ratios ranging from 0.54 (95% CI = 0.38 to 0.78) to 0.88 (95% CI = 0.84 to 0.93) for Japanese patients with prostate and Chinese patients with lung cancer, respectively. CONCLUSIONS Despite adjustment for potential confounders, including the receipt of definitive treatment and tumor characteristics, most Asian subgroups had better CSM than non-Hispanic white patients. These findings suggest that underlying genetic/biological differences, along with potential cultural variations, may impact survival in Asian American cancer patients.

Abstract
OBJECTIVES Treating high-risk prostate cancer (CaP) with definitive therapy improves survival. We evaluated whether having health insurance reduces racial disparities in the use of definitive therapy for high-risk CaP. MATERIALS AND METHODS The Surveillance, Epidemiology, and End Results Program was used to identify 70,006 men with localized high-risk CaP (prostate-specific antigen level > 20 ng/ml or Gleason score 8-10 or stage > cT3a) diagnosed from 2007 to 2010. We used multivariable logistic regression to analyze the 64,277 patients with complete data to determine the factors associated with receipt of definitive therapy. RESULTS Compared with white men, African American (AA) men were significantly less likely to receive definitive treatment (adjusted odds ratio [AOR] = 0.60; 95% CI: 0.56-0.64; P < 0.001) after adjusting for sociodemographics and known CaP prognostic factors. There was a significant interaction between race and insurance status (P interaction = 0.01) such that insurance coverage was associated with a reduction in racial disparity between AA and white patients regarding receipt of definitive therapy. Specifically, the AOR for definitive treatment for AA vs. white was 0.38 (95% CI: 0.27-0.54, P < 0.001) among uninsured men, whereas the AOR was 0.62 (95% CI: 0.57-0.66, P < 0.001) among insured men. CONCLUSIONS AA men with high-risk CaP were significantly less likely to receive potentially life-saving definitive treatment when compared with white men. Having health insurance was associated with a reduction in this racial treatment disparity, suggesting that expansion of health insurance coverage may help reduce racial disparities in the management of aggressive cancers.

Abstract
Purpose: We conducted the present retrospective study to elucidate regional differences in the quality of secondary screening in the prostate cancer (PCA) screening program by a local municipality in Japan. Methods: Of 115,881 men who attended the PCA screening in 36 municipalities between 2001 and 2011, a total of 6,099 men consulted hospitals for secondary screening. The cancer detection rate (CDR) at the secondary screening was calculated, and municipalities were classified into three CDR groups according to the age-adjusted observed-to-expected ratios of CDR. Of the secondary screening facilities, hospitals in Ibaraki Prefecture screening less than 100 patients were classified as group I facilities and the others as group II facilities. Results: Overall, 2,320 of 6,099 secondary screening patients underwent prostate biopsy, and 1,073 men were diagnosed with PCA. The overall CDR at the secondary screening was 17.6%, but it varied from 5.6% to 34.4% among municipalities. Although there were no significant differences in age and prostate-specific antigen (PSA) distribution among the three CDR groups, a significantly higher rate of patients in low CDR municipalities visited group I facilities. Both biopsy rates and CDRs of secondary screening at group II facilities were significantly higher than those of group I facilities (P=0.0001). Multivariate analysis showed that the secondary screening at group II facilities as well as age and PSA levels were independent contributing factors for PCA detection. Conclusions: CDRs at secondary screening varied widely among municipalities in Ibaraki Prefecture. Variation in CDRs was associated with biopsy rates.
