Our study investigates the trends in prostate cancer screening amid the COVID-19 pandemic, particularly focusing on racial disparities between Black and White men. Utilizing data from the Behavioral Risk Factor Surveillance System from 2018, 2020, and 2022, we analyzed prostate-specific antigen screening rates in men aged 45-75 years. Our findings reveal initial declines in screening rates for both groups during the pandemic, with subsequent recovery; however, the pace of rebound differed statis ...[more]

Project description:BackgroundWidespread use of prostate-specific antigen (PSA) to screen for prostate cancer began in the early 1990s. Advocates for screening assert that this has caused a decrease in prostate cancer mortality. We sought to describe secular changes in prostate cancer incidence and mortality in Canada in relation to the onset of PSA screening.MethodsAge-standardized and age-specific prostate cancer incidence (1969-2007) and mortality (1969-2009) from Public Health Agency of Canada databases were analyzed by joinpoint regression. Changes in incidence and mortality were related to introduction of PSA screening.ResultsPrior to PSA screening, prostate cancer incidence increased from 54.2 to 99.8 per 100 000 between 1969 and 1990. Thereafter, incidence increased sharply (12.8% per year) to peak at 140.8/100 000 in 1993. After decreasing in all age groups between 1993 and 1996, incidence continued to increase for men aged less than 70 years, but decreased for older men. Age-standardized mortality was stable from 1969 to 1977, increased 1.4% per year to peak in 1995 and subsequently decreased at 3.3% per year; the decline started from 1987 in younger men (age < 60 yr).InterpretationIncidence was increasing before PSA screening occurred, but rose further after it was introduced. Reductions in prostate cancer mortality began before PSA screening was widely used and were larger than could be anticipated from screening alone. These findings suggest that screening caused artifactual increase in incidence, but no more than a part of reductions in prostate cancer mortality. The reduction may be due to changing treatment or certification of death.

Project description:ObjectiveTo characterize national trends in and associated outcomes of more often than annual prostate-specific antigen (PSA) screening, which we term "prosteria."MethodsMen in the Optum Clinformatics Data Mart with ≥2 years from first PSA test to censoring at the end of insurance or available data (January 2003 to June 2019) or following exclusionary diagnoses or procedures, such as PCa treatment, were included. PSAs within 90 days were treated as one PSA. Prosteria was defined as having ≥3 PSA testing intervals of ≤270 days.ResultsA total of 9,734,077 PSAs on 2,958,923 men were included. The average inter-PSA testing interval was 1.5 years, and 4.5% of men had prosteria, which increased by 0.53% per year. Educated, wealthy, non-White patients were more likely to have prosteria. Men within the recommended screening age (ie 55-69) had lower rates of prosteria. Prosteria patients had higher average PSA values (2.5 vs 1.4 ng/mL), but lower values at PCa diagnosis. Prosteria was associated with biopsy and PCa diagnosis; however, there were comparable rates of treatment within 2 years of diagnosis.ConclusionIn this large cohort study, prosteria was common, increased over time, and was associated with demographic characteristics. Importantly, there were no clinically meaningful differences in PSA values at diagnosis or rates of early treatment, suggesting prosteria leads to both overdiagnosis and overtreatment. These results support current AUA and USPTF guidelines and can be used to counsel men seeking more frequent PSA screening.

Project description:IntroductionFor many men, the net benefit of prostate cancer screening with prostate-specific antigen (PSA) tests may be small. Many major medical organizations have issued recommendations for prostate cancer screening, stressing the need for shared decision making before ordering a test. The purpose of this study is to better understand associations between discussions about benefits and harms of PSA testing and uptake of the test among men aged ≥40 years.MethodsAssociations between pre-screening discussions and PSA testing were examined using self-reported data from the 2012 Behavioral Risk Factor Surveillance System. Unadjusted prevalence of PSA testing was estimated and AORs were calculated using logistic regression in 2014.ResultsThe multivariate analysis showed that men who had ever discussed advantages of PSA testing only or discussed both advantages and disadvantages were more likely, respectively, to report having had a test within the past year than men who had no discussions (p<0.001). In addition, men who had only discussed the disadvantages of PSA testing with their healthcare providers were more likely (AOR=2.75, 95% CI=2.00, 3.79) to report getting tested than men who had no discussions.ConclusionsDiscussions of the benefits or harms of PSA testing are positively associated with increased uptake of the test. Given the conflicting recommendations for prostate cancer screening and increasing importance of shared decision making, this study points to the need for understanding how pre-screening discussions are being conducted in clinical practice and the role played by patients' values and preferences in decisions about PSA testing.

Project description:The European Randomized study of Screening for Prostate Cancer (ERSPC) has shown a 20% relative reduction in prostate cancer mortality after 16yr [rate ratio (RR) 0.80], but centers varied by attendance, screen interval, biopsy compliance, contamination in the control arm, and treatments. We used a microsimulation model, calibrated to the ERSPC individual-level data, to predict influence of study features on the results. The relative reduction in prostate cancer mortality would have been somewhat larger with improved study features: increased attendance (90% attendance in all volunteer-based and 70% in all population-based centers, resulting in RR 0.77), a 2-yr screen interval (RR 0.75), and an 80% biopsy compliance (RR 0.79). The RR would have been substantially lower with a 30% attendance (RR 0.92), 40% biopsy compliance (RR 0.90), or 100% contamination (RR 0.85). The variations in results by trial center may reflect differences in study design and performance and results of our simulations highlight the effect of quality indicators in prostate-specific antigen screening in different settings. PATIENT SUMMARY: We evaluated the effect of various features of prostate-specific antigen (PSA) screening on its effectiveness. The compliance to PSA testing and those having a biopsy after an elevated PSA substantially influence the prostate cancer mortality.

Project description:(1) Background: A simulation approach for prostate cancer (PrCa) with a prostate-specific antigen (PSA) test incorporating genetic information provides a new avenue for the development of personalized screening for PrCa. Going by the evidence-based principle, we use the simulation method to evaluate the effectiveness of mortality reduction resulting from PSA screening and its utilization using a personalized screening regime as opposed to a universal screening program. (2) Methods: A six-state (normal, over-detected, low-grade, and high-grade PrCa in pre-clinical phase, and low-grade and high-grade PrCa in clinical phase) Markov model with genetic and PSA information was developed after a systematic review of genetic variant studies and dose-dependent PSA studies. This gene‒PSA-guided model was used for personalized risk assessment and risk stratification. A computer-based simulated randomized controlled trial was designed to estimate the reduction of mortality achieved by three different screening methods, personalized screening, universal screening, and a non-screening group. (3) Results: The effectiveness of PrCa mortality reduction for a personalized screening program compared to a non-screening group (22% (9%‒33%)) was similar to that noted in the universal screening group (20% (7%‒21%). However, a personalized screening program could dispense with 26% of unnecessary PSA testing, and avoid over-detection by 2%. (4) Conclusions: Gene‒PSA-guided personalized screening for PrCa leads to fewer unnecessary PSA tests without compromising the benefits of mortality reduction (as happens with the universal screening program).

Project description:Recent studies show decreasing prostate-specific antigen utilization and increasing incidence of metastatic prostate cancer in the United States after national recommendations against screening in 2012. Yet, whether the increasing incidence of metastatic prostate cancer is consistent in magnitude with the expected impact of decreased screening is unknown. We compared observed incidence of metastatic prostate cancer from the Surveillance, Epidemiology, and End Results program and published effects of continued historical screening and discontinued screening starting in 2013 projected by 2 models of disease natural history, screening, and diagnosis. The observed rate of new metastatic prostate cancer cases in 2017 was 44%-60% of the projected increase under discontinued screening relative to continued screening. Thus, the observed increase in incident metastatic prostate cancer is consistent with the expected impact of reduced screening. Although this comparison does not establish a causal relationship, it highlights the plausible role of decreased screening in the observed trend.

Project description:ObjectiveTo determine the distribution of screening prostate-specific antigen (PSA) values in older men, and how different PSA thresholds affect the proportion of white, black, and Latino men who would have an abnormal screening result across advancing age groups.MethodsWe used linked national Veterans Affairs and Medicare data to determine the value of the first screening PSA test (ng/mL) of 327,284 men older than 65 years who underwent PSA screening in the Veterans Affairs health care system in 2003. We calculated the proportion of men with an abnormal PSA result based on age, race, and common PSA thresholds.ResultsAmong men older than 65 years, 8.4% had a PSA >4.0 ng/mL. The percentage of men with a PSA >4.0 ng/mL increased with age and was highest in black men (13.8%) vs white (8.0%) or Latino men (10.0%) (P <.001). Combining age and race, the probability of having a PSA >4.0 ng/mL ranged from 5.1% of Latino men aged 65-69 years to 27.4% of black men older than 85 years. Raising the PSA threshold from >4.0 ng/mL to >10.0 ng/mL reclassified the greatest percentage of black men older than 85 years (18.3% absolute change) and the lowest percentage of Latino men aged 65-69 years (4.8% absolute change) as being under the biopsy threshold (P <.001).ConclusionAge, race, and PSA threshold together affect the pretest probability of an abnormal screening PSA result. Based on screening PSA distributions, stopping screening among men whose PSA <3 ng/mL means more than 80% of white and Latino men older than 70 years would stop further screening, and increasing the biopsy threshold to >10 ng/mL has the greatest effect on reducing the number of older black men who will face biopsy decisions after screening.

Project description:BackgroundProstate-specific antigen (PSA) screening for prostate cancer has high risks of overdiagnosis, particularly among older men, and reports from screening trials indicate that it saves few lives after 11 to 13 years of follow-up. New clinical guidelines recommend against PSA screening for all men or for men aged >70 years, but, to the authors' knowledge, the expected population effects of these guidelines have not been studied to date.MethodsTwo models of prostate cancer natural history and diagnosis were previously developed using reconstructed PSA screening patterns and prostate cancer incidence in the United States. Assuming a survival benefit of PSA screening consistent with the screening trials, the authors used the models to predict incidence and mortality rates for the period from 2013 through 2025 under continued PSA screening and under discontinued PSA screening for all men or for men aged >70 years.ResultsThe models predicted that continuation of recent screening rates will overdiagnose 710,000 to 1,120,000 men (range between models) but will avoid 36,000 to 57,000 cancer deaths over the period 2013 through 2025. Discontinued screening for all men eliminated 100% of overdiagnoses but failed to prevent 100% of avoidable cancer deaths. Continued screening for men aged <70 years eliminated 64% to 66% of overdiagnoses but failed to prevent 36% to 39% of avoidable cancer deaths.ConclusionsDiscontinuing PSA screening for all men may generate many avoidable cancer deaths. Continuing PSA screening for men aged <70 years could prevent greater than one-half of these avoidable cancer deaths while dramatically reducing overdiagnoses compared with continued PSA screening for all ages.

Project description:After 11 years of follow-up, the European Randomized Study of Screening for Prostate Cancer (ERSPC) reported a 29% reduction in prostate-cancer mortality among men who underwent screening for prostate-specific antigen (PSA) levels. However, the extent to which harms to quality of life resulting from overdiagnosis and treatment counterbalance this benefit is uncertain.On the basis of ERSPC follow-up data, we used Microsimulation Screening Analysis (MISCAN) to predict the number of prostate cancers, treatments, deaths, and quality-adjusted life-years (QALYs) gained after the introduction of PSA screening. Various screening strategies, efficacies, and quality-of-life assumptions were modeled.Per 1000 men of all ages who were followed for their entire life span, we predicted that annual screening of men between the ages of 55 and 69 years would result in nine fewer deaths from prostate cancer (28% reduction), 14 fewer men receiving palliative therapy (35% reduction), and a total of 73 life-years gained (average, 8.4 years per prostate-cancer death avoided). The number of QALYs that were gained was 56 (range, -21 to 97), a reduction of 23% from unadjusted life-years gained. To prevent one prostate-cancer death, 98 men would need to be screened and 5 cancers would need to be detected. Screening of all men between the ages of 55 and 74 would result in more life-years gained (82) but the same number of QALYs (56).The benefit of PSA screening was diminished by loss of QALYs owing to postdiagnosis long-term effects. Longer follow-up data from both the ERSPC and quality-of-life analyses are essential before universal recommendations regarding screening can be made.

Project description:ImportanceThe US Preventive Services Task Force guidelines advise against prostate-specific antigen (PSA) screening for prostate cancer in males older than 69 years due to the risk of false-positive results and overdiagnosis of indolent disease. However, this low-value PSA screening in males aged 70 years or older remains common.ObjectiveTo characterize the factors associated with low-value PSA screening in males 70 years or older.Design, setting, and participantsThis survey study used data from the 2020 Behavioral Risk Factor Surveillance System (BRFSS), a nationwide annual survey conducted by the Centers for Disease Control and Prevention that collects information via telephone from more than 400 000 US adults on behavioral risk factors, chronic illnesses, and use of preventive services. The final cohort comprised male respondents to the 2020 BRFSS survey who were categorized into the following age groups: 70 to 74 years, 75 to 79 years, or 80 years or older. Males with a former or current prostate cancer diagnosis were excluded.Main outcomes and measuresThe outcomes were recent PSA screening rates and factors associated with low-value PSA screening. Recent screening was defined as PSA testing within the past 2 years. Weighted multivariable logistic regressions and 2-sided significance tests were used to characterize factors associated with recent screening.ResultsThe cohort included 32 306 males. Most of these males (87.6%) were White individuals, whereas 1.1% were American Indian, 1.2% were Asian, 4.3% were Black, and 3.4% were Hispanic individuals. Within this cohort, 42.8% of respondents were aged 70 to 74 years, 28.4% were aged 75 to 79 years, and 28.9% were 80 years or older. The recent PSA screening rates were 55.3% for males in the 70-to-74-year age group, 52.1% in the 75-to-79-year age group, and 39.4% in the 80-year-or-older group. Among all racial groups, non-Hispanic White males had the highest screening rate (50.7%), and non-Hispanic American Indian males had the lowest screening rate (32.0%). Screening increased with higher educational level and annual income. Married respondents were screened more than unmarried males. In a multivariable regression model, discussing PSA testing advantages with a clinician (odds ratio [OR], 9.09; 95% CI, 7.60-11.40; P < .001) was associated with increased recent screening, whereas discussing PSA testing disadvantages had no association with screening (OR, 0.95; 95% CI, 0.77-1.17; P = .60). Other factors associated with a higher screening rate included having a primary care physician, a post-high school educational level, and income of more than $25 000 per year.Conclusions and relevanceResults of this survey study suggest that older male respondents to the 2020 BRFSS survey were overscreened for prostate cancer despite the age cutoff for PSA screening recommended in national guidelines. Discussing the benefits of PSA testing with a clinician was associated with increased screening, underscoring the potential of clinician-level interventions to reduce overscreening in older males.
