Although research has reported that prostate cancer (PCa) incidence and mortality rates are among the highest for African Americans, the data is inconclusive regarding PCa rates in native African men, Black men residing in other countries, and men in Asia, Europe, and the Americas. Data reveals that prostate-specific antigen (PSA) testing and disease incidence have risen significantly in developing and Asian countries, and PCa has become one of the leading male cancers in many of those nations. The objective of this study was to review published peer-reviewed studies that address PCa in different regions of the world to get a better understanding of how PCa incidence, prevalence, detection, and mortality are influenced by race, ethnicity, and geography. A secondary goal was to compare PCa data from various world regions to contextualize how disproportionate the incidence and mortality rates are among men from the African diaspora versus men of European, Hispanic, and Asian descent, as well as to highlight the need for more robust screening and treatment guidelines in developing countries. There are differences in incidence and mortality rates between men of African, Asian, Hispanic, and European ancestry, confirming the involvement of genetic factors. However, differences between men of the same race and ethnicity who live in different countries suggest that environmental factors may also be implicated. Availability and access to diagnostic and health-care services as well as recommendations regarding PCa testing vary from country to country and contribute to the variability in incidence and mortality rates.

Over Time

Prostate cancer differently affects different regions of the world, displaying higher rates in more developed areas. After the implementation of prostate-specific antigen (PSA) testing, several studies described rising rates globally, but it is possible that indolent lesions are being detected given the lack of changes in mortality data. The Brazilian government recommends against PSA screening in the male population regardless of age, but the Urology Society issued a report recommending that screening should start at 50 years old for certain men and for those aged ≥75 years with a life expectancy exceeding 10 years. In this study, we examined the incidence and mortality rates of invasive prostate cancer over time in the Sergipe state of Brazil. The databases of the Aracaju Cancer Registry and Mortality Information System were used to calculate age-standardized rates for all prostate tumors (International Classification of Diseases 10th edition: C61 and D07.5) in the following age ranges: 20–44, 45–54, and ≥65 years. We identified 3595 cases of cancer, 30 glandular intraepithelial high-grade lesions, and 3269 deaths. Using the Joinpoint Regression Program, we found that the incidence of prostate cancer dramatically increased over time until the mid-2000s for all age groups, after which the rates declined. Prostate cancer mortality rates increased until 2005, followed by a non-significant annual percent change of 22.0 in 2001–2005 and a stable rate thereafter. We noticed that the increases and decreases of the incidence rates of prostate cancer were associated with the screening recommendations. Meanwhile, the increased mortality rates did not appear to be associated with decreased PSA testing; instead, they were linked to the effects of age and improvements in identification of the cause of death. Thus, we do not believe a PSA screening program would benefit the population of this study.

BackgroundProstate cancer (PCa) is the most frequent cancer among men in Europe. Differences in PCa incidence around the world can be partly explained by variations in recommendations for prostate-specific antigen (PSA), particularly for early detection. For example, the PSA testing policy is more conservative in the Netherlands than in Germany. To better understand the relationship between PSA testing recommendations and PCa incidence, stage distribution, and mortality, we compared these variables over time between Lower Saxony in northwestern Germany and the neighboring province of Groningen in the Netherlands.MethodsPopulation data, tumor stage- and age group-specific PCa incidence (ICD-10 C61) and mortality rates for Lower Saxony and Groningen were obtained from the Lower Saxony Epidemiological Cancer Registry, the Netherlands Comprehensive Cancer Organization, and Statistics Netherlands for 2003–2012. Incidence and mortality rates per 100,000 person-years were age-standardized (ASR, old European standard). Trends in age-standardized incidence rates (ASIR) and mortality rates (ASMR) for specific age groups were assessed using joinpoint regression.ResultsThe mean annual PCa ASIR between 2003 and 2012 was on average 19.9% higher in Lower Saxony than in Groningen (120.5 vs. 100.5 per 100,000), while the mean annual ASMR was on average 24.3% lower in Lower Saxony than in Groningen (21.5 vs. 28.4 per 100,000). Between 2003 and 2012, the average annual percentage change (AAPC) in PCa incidence rates did not change significantly in either Lower Saxony (−1.8%, 95% CI −3.5, 0.0) or Groningen (0.2%, 95% CI −5.0, 5.7). In contrast, the AAPC in mortality rate decreased significantly during the same time period in Lower Saxony (−2.5%, 95% CI −3.0, −2.0) but not in Groningen (0.1%, 95% CI −2.4, 2.6).ConclusionsHigher PCa incidence and lower PCa-related mortality was detected in Lower Saxony than in Groningen. Although recommendations on PSA testing may play a role, the assessed data could not offer obvious explanations to the observed differences. Therefore, further investigations including data on the actual use of PSA testing, other influences (e.g., dietary and ethnic factors), and better data quality are needed to explain differences between the regions.

Abstract BackgroundPopulation trends in PSA screening and prostate cancer incidence do not perfectly correspond. We aimed to better understand relationships between trends in PSA screening, prostate cancer incidence and mortality in Australia.MethodsDescription of age standardised time trends in PSA tests, prostate biopsies, cancer incidence and mortality within Australia for the age groups: 45-74, 75-84, and 85+ years.ResultsPSA testing increased from its introduction in 1989 to a peak in 2008. It then declined in men aged 45-84 years. Prostate biopsies and cancer incidence declined from 1995 to 2000, in parallel with decrease in trans-urethral resections of prostate (TURP). After 2000, changes in biopsies and cancer incidence paralleled PSA screening in men 45-84 years, while in men ≥85 years, biopsies stabilised and incidence declined. More recently a reduction in TURP correlated with increased Dutasteride and Tamsulosin usage. Prostate cancer mortality in men aged 45-74 years remained low throughout. Mortality in men 75-84 years gradually increased until the mid 1990s, then gradually decreased. Mortality in men ≥85 years increased until the mid 1990s, then stabilised.ConclusionsAge specific prostate cancer incidence largely mirrors PSA screening rates. Most deviation may be explained by changes in management of benign prostatic disease and incidental cancer detection. The timing of the small mortality reduction in men 75-84 years is more consistent with benefits from advances in treatment than with early detection through PSA. The large increases in prostate cancer incidence with minimal changes in mortality suggest overdiagnosis.

Incidence And Mortality

115 Background: Many men with an initial negative prostate biopsy have a persistently elevated prostate specific antigen (PSA) prompting physicians to perform repeat biopsies. African American men (AA) are at particular risk as they have a greater prostate cancer (PCa) incidence and mortality, yet traditional PSA testing may be less reliable in this cohort. We sought to determine the predictors of PCa and PCa severity in a racially diverse population on subsequent biopsy following an initial benign biopsy. Methods: Upon receiving Institutional Review Board approval, a retrospective analysis was performed on men with repeat prostate biopsies at Tulane Medical Center and Southeast Louisiana Veterans Health Care Services in New Orleans, Louisiana from 2003-2015. Inclusion criteria included patients with a benign initial prostate biopsy and underwent subsequent repeat prostate biopsy within 5 years. Race, age, serum PSA, PSA density (PSAD), and prostate volume by transrectal ultrasound (TRUS) were evaluated to determine if they correlate with the presence and severity of PCa. Aggressive PCa was defined as Gleason score >6. Results: A total of 209 men were included; 127 (61%) were AA, and 82 (39%) were Caucasian American men (CA). The two groups were similar with respect to PSA, PSAD, and TRUS. More AA (25.2% vs. 17.1%) had a repeat biopsy showing any PCa. Of those with PCa, 28.1% of AA and 28.6% of CA had aggressive PCa. PSAD positively correlated with any PCa (p=.015). TRUS negatively correlated with any PCa (p=.008). PSA levels (p<.001) and PSAD (p<.001) positively correlated with aggressive PCa in CA but not in AA. Conclusions: The goal of prostate biopsy particularly for those with a prior negative biopsy is to detect aggressive PCa. PSA and PSAD positively correlated with finding any PCa in both AA and CA but not with aggressive PCa in AA. PSA and PSAD are less accurate predictors of aggressive PCa in AA, and novel biomarkers are needed. [Table: see text]

Abstract Background The 2012 US Preventive Services Task Force recommendation against routine prostate-specific antigen (PSA) testing led to a decrease in prostate cancer screening, but the heterogeneity of its impact by race and ethnicity remains unclear. Methods The proportion of 40- to 74-year-old men who self-reported receiving a routine PSA test in the past year was estimated in the Behavioral Risk Factor Surveillance System (2012-2018). Odds ratios (ORs) of undergoing screening by race and ethnicity were estimated, adjusting for healthcare–related factors. Prostate cancer incidence rates and rate ratios (IRRs) by race and ethnicity were estimated using Surveillance, Epidemiology, and End Results registry data (2004-2017). Results PSA testing frequencies were 32.3% (95% confidence interval [CI] = 31.7% to 32.8%) among non-Hispanic White (NHW), 30.3% (95% CI = 28.3% to 32.3%) among non-Hispanic Black (NHB), 21.8% (95% CI = 19.9% to 23.7%) among Hispanic, and 17.7% (95% CI = 14.1% to 21.3%) among Asian and Pacific Islander men in 2012. The absolute screening frequency declined by 9.5% from 2012 to 2018, with a larger decline among NHB (11.6%) than NHW men (9.3%). The relative annual decrease was greater among NHB (OR = 0.86, 95% CI = 0.84 to 0.88) than NHW men (OR = 0.89, 95% CI = 0.89 to 0.90; Pheterogeneity = .005), driven by a larger decline among NHB men ages 40-54 years. The NHB to NHW IRR for total prostate cancer increased from 1.73 (95% CI = 1.69 to 1.76) in 2011 to 1.87 (95% CI = 1.83 to 1.92) in 2012 and has remained elevated, driven by differences in localized tumor incidence. Metastatic disease incidence is rising across all racial and ethnic groups. Conclusions The frequency of prostate cancer screening varies by race and ethnicity, and there was a modestly steeper decline in PSA testing among younger NHB men relative to NHW men since 2012. The NHB to NHW IRR for localized prostate cancer modestly increased following 2012.

Background: Polygenic hazard scores (PHS) can identify individuals with increased risk of prostate cancer. We estimated the benefit of additional SNPs on performance of a previously validated PHS (PHS46). Materials and Method: 180 SNPs, shown to be previously associated with prostate cancer, were used to develop a PHS model in men with European ancestry. A machine-learning approach, LASSO-regularized Cox regression, was used to select SNPs and to estimate their coefficients in the training set (75,596 men). Performance of the resulting model was evaluated in the testing/validation set (6,411 men) with two metrics: (1) hazard ratios (HRs) and (2) positive predictive value (PPV) of prostate-specific antigen (PSA) testing. HRs were estimated between individuals with PHS in the top 5% to those in the middle 40% (HR95/50), top 20% to bottom 20% (HR80/20), and bottom 20% to middle 40% (HR20/50). PPV was calculated for the top 20% (PPV80) and top 5% (PPV95) of PHS as the fraction of individuals with elevated PSA that were diagnosed with clinically significant prostate cancer on biopsy. Results: 166 SNPs had non-zero coefficients in the Cox model (PHS166). All HR metrics showed significant improvements for PHS166 compared to PHS46: HR95/50 increased from 3.72 to 5.09, HR80/20 increased from 6.12 to 9.45, and HR20/50 decreased from 0.41 to 0.34. By contrast, no significant differences were observed in PPV of PSA testing for clinically significant prostate cancer. Conclusion: Incorporating 120 additional SNPs (PHS166 vs PHS46) significantly improved HRs for prostate cancer, while PPV of PSA testing remained the same.

Racial and ethnic inequities in health abound in many disease categories. African-American communities suffer from an increased burden of illness, with higher incidence and mortality rates and more severe morbidity in cerebrovascular disease, heart disease, several cancers, diabetes, and many other ailments. Healthy People 2010, the federal government's health plan, calls for eliminating health disparities by race, ethnicity, gender, education, income, disability, geographic location, or sexual orientation. Research aimed at increasing our understanding of these health disparities and designing and evaluating interventions to improve African-American health is hampered by a liberal, classless approach. The authors argue for a theoretical framework in this research that recognizes that class exploitation sets the stage for and interacts with racial discrimination to determine racial inequities in health.

AbstractProstate cancer is the second most common solid tumour in men worldwide and it is also the most common cancer affecting men of African descent. Prostate cancer incidence and mortality vary across regions and populations. Some of this is explained by a large heritable component of this disease. It has been established that men of African and African Caribbean ethnicity are predisposed to prostate cancer (PrCa) that can have an earlier onset and a more aggressive course, thereby leading to poorer outcomes for patients in this group. Literature searches were carried out using the PubMed, EMBASE and Cochrane Library databases to identify studies associated with PrCa risk and its association with ancestry, screening and management of PrCa. In order to be included, studies were required to be published in English in full-text form. An attractive approach is to identify high-risk groups and develop a targeted screening programme for them as the benefits of population-wide screening in PrCa using prostate-specific antigen (PSA) testing in general population screening have shown evidence of benefit; however, the harms are considered to weigh heavier because screening using PSA testing can lead to over-diagnosis and over-treatment. The aim of targeted screening of higher-risk groups identified by genetic risk stratification is to reduce over-diagnosis and treat those who are most likely to benefit.
