Prostate-specific antigen (PSA) in combination with digital rectal examination forms the basis for current prostate cancer (CaP) screening programs. Although PSA screening was recently shown to reduce CaP-specific mortality in the European randomized trial, its limitations include the risk for unnecessary prostate biopsy and the diagnosis and treatment of some CaP that might never have caused suffering or death. A potential way to minimize these pitfalls is through the use of derivatives of PSA, particularly PSA kinetics, to increase the specificity for clinically relevant CaP. CaP is the second-leading cause of cancer death in men in the United States and many other westernized countries; accordingly, judicious screening of healthy men allows for diagnosis sufficiently early that all options (i.e., treatment or surveillance) are still available in most cases.

Objectives If prostate cancer screening practices relate to occupation, this would have important implications when studying the aetiological role of workplace exposures on prostate cancer. We identified variations in screening by occupation among men in Montreal, Canada (2005–2012). Methods Prostate specific antigen testing and digital rectal examination (ever-screened and frequency of screening, previous five years) were examined among population controls from the Prostate Cancer & Environment Study. Face-to-face interviews elicited lifestyle and occupational histories. Multivariable logistic regression was used to estimate the odds of ever-screening for the longest-held occupation, adjusting for potential confounders. Negative binomial models were used to examine relationships with screening frequency. Results Among 1989 controls, 81% reported ever having had a prostate specific antigen test, and 77% a digital rectal examination. Approximately 40% of men reported having a prostate specific antigen test once a year, on average. Compared with those in management or administrative jobs, men in primary industry (odds ratio 0.26, 95% confidence interval 0.10–0.65), construction (0.44, 0.25–0.79), machining (0.45, 0.21–0.97), and teaching (0.37, 0.20–0.70) were less likely to have undergone prostate specific antigen screening. Results were similar when considering the most recent job. Conclusions Our findings highlight substantial variations in prostate cancer screening by occupation. Men in occupations where carcinogen exposures are more common are less likely to participate in prostate screening activities. This could be an important source of bias, and occupational studies of prostate cancer should account for screening practices.

Purpose: To determine whether pretreatment risk groups shown to predict time to prostate cancer–specific mortality (PCSM) after treatment at a single institution retained that ability in a multi-institutional setting. Patients and Methods: From 1988 to 2002, 7,316 patients treated in the United States at 44 institutions with either surgery (n = 4,946) or radiation (n = 2,370) for clinical stage T1c-2, N0 or NX, M0 prostate cancer made up the study cohort. A Cox regression analysis was performed to determine the ability of pretreatment risk groups to predict time to PCSM after treatment. The relative risk (RR) of PCSM and 95% confidence intervals (CIs) were calculated for the intermediate- and high-risk groups relative to the low-risk group. Results: Estimates of non-PCSM 8 years after prostate-specific antigen (PSA) failure were 4% v 15% (surgery versus radiation; Plog rank = .002) compared with 13% v 18% (surgery versus radiation; Plog rank = .35) for patients whose age at the time of PSA failure was less than 70 as compared with ≥ 70 years, respectively. The RR of PCSM after treatment for surgery-managed patients with high- or intermediate-risk disease was 14.2 (95% CI, 5.0 to 23.4; PCox < .0001) and 4.9 (95% CI, 1.7 to 8.1; PCox = .0037), respectively. These values were 14.3 (95% CI, 5.2 to 24.0; PCox < .0001) and 5.6 (95% CI, 2.0 to 9.3; PCox = .0012) for radiation-managed patients. Conclusion: This study provided evidence to support the prediction of time to PCSM after surgery or radiation on the basis of pretreatment risk groups for patients with clinically localized prostate cancer managed during the PSA era.

Introduction: This study serves as an update of prostate cancer screening practices among family physicians in Ontario, Canada. Since this population was first surveyed in 2010, the Canadian Task Force on Preventive Health Care (CTFPHC) and the United States Preventive Services Task Force (USPSTF) released recommendations against prostate cancer screening.Methods: An online survey was developed through input from urologists and family practitioners. It was distributed via email to all members of the Ontario Medical Association’s Section on General and Family practice (11 657 family physicians). A reminder email was sent at two weeks and the survey remained active for one month.Results: A total of 1880 family physicians completed surveys (response rate 16.1%). Overall, 80.4% offered prostate cancer screening compared to 91.7% when surveyed in 2010. Physicians new to practice (two years or less) were the most likely to not offer screening (24.6%). A combination of digital rectal exam (DRE) and prostate-specific antigen (PSA) remained the most common form of screening (58.3%). Following the release of the CTFPHC recommendations, 45.6% of respondents said they now screen fewer patients. Participants were less familiar with national urological society guidelines compared to task force recommendations. The majority (72.6%) of respondents feel PSA screening leads to overdiagnosis and treatment. Those surveyed remained split with respect to PSA utility.Conclusions: Data suggest a decline in screening practices since 2010, with newer graduates less likely to offer screening. CFTPHC and USPSTF recommendations had the greatest impact on clinical practice. Those surveyed were divided with respect to PSA utility. Some additional considerations to PSA screening in the primary care setting, including patient-driven factors, were not captured by our concise survey.

ObjectivesTo investigate men’s values and preferences regarding prostate-specific antigen (PSA)-based screening for prostate cancer.DesignSystematic review.Data sourcesWe searched MEDLINE, EMBASE, PsycINFO and grey literature up to 2 September 2017.Eligibility criteriaPrimary studies of men’s values and preferences regarding the benefits and harms of PSA screening.Data extraction and synthesisTwo independent reviewers extracted data and assessed risk of bias with a modified version of a risk of bias tool for values and preferences studies, the International Patient Decision Aid Standards instrument V.3 and the Cochrane Collaboration risk of bias tool.ResultsWe identified 4172 unique citations, of which 11 studies proved eligible. Five studies investigated PSA screening using a direct choice study design, whereas six used decisions aids displaying patient-important outcomes. The direct choice studies used different methodologies and varied considerably in the reporting of outcomes. Two studies suggested that men were willing to forego screening with a small benefit in prostate cancer mortality if it would decrease the likelihood of unnecessary treatment or biopsies. In contrast, one study reported that men were willing to accept a substantial overdiagnosis to reduce their risk of prostate cancer mortality. Among the six studies involving decision aids, willingness to undergo screening varied substantially from 37% when displaying a hypothetical reduction in mortality of 10 per 1000 men, to 44% when displaying a reduction in mortality of 7 per 1000. We found no studies that specifically investigated whether values and preferences differed among men with family history, of African descent or with lower socioeconomic levels.ConclusionThe variability of men’s values and preferences reflect that the decision to screen is highly preference sensitive. Our review highlights the need for shared decision making in men considering prostate cancer screening.Trial registration numberCRD42018095585.

Abstract Objectives— To assess motives for attending a randomised population based prostate cancer screening trial, and to assess acceptance of screening and invitation procedures. Methods— First pilot of the European Randomised Study of Screening for Prostate Cancer (ERSPC; 1992/1993). Men aged 55–75 years, randomly selected from the population register of four city districts of Rotterdam, were invited by a single invitation for screening. Screening consisted of prostate specific antigen prescreening followed by either (1) digital rectal examination, transrectal ultrasound, and, on indication, biopsy, or (2) no additional screening. After screening, or in the case of non-attendance, a questionnaire was sent to a random sample of 600 attenders and 400 non-attenders, with a reminder after three weeks. Outcome measures— In both attenders and non-attenders: Knowledge of prostate cancer, attitudes towards screening, motives for attending, procedural aspects and sociodemographic characteristics. In attenders, acceptance of screening procedures. Results— The response rate for the questionnaire was 76%: 94% in attenders and 42% in non-attenders. The main reasons for attending were expected personal benefit (76%) and scientific value (39%), and those for not attending were the absence of urological complaints (41%) and anticipated pain or discomfort (24%). Uptake of screening was 32%, which increased to a sustained 42% in following years. Attenders, compared with non-attenders, were significantly younger, more often married, better educated, and had higher perceived health status, more knowledge about prostate cancer, and a more positive attitude towards screening. Information materials and invitation procedure were adequate. Screening procedures were well accepted (high report marks and satisfaction, and 95% would attend for rescreening). A single prostate specific antigen determination was liked less than a combination of all three screening modalities. Conclusions— (1) The main reasons for attending are personal benefit and science, and those for not attending were absence of urological complaints and anticipated pain or discomfort; (2) knowledge, attitudes, and motives for attending are comparable with other screening programmes; hence, for population based prostate cancer screening, known health promotional aspects should be carefully considered; (3) prostate specific antigen, digital rectal examination and transrectal ultrasound are acceptable to attenders.

Purpose For patients who elect to have prostate cancer screening, the optimal time to discontinue screening is unknown. Our objective was to describe rates and predictors of prostate-specific antigen (PSA) screening among older men in the United States. Methods Data were extracted from the population-based 2000 and 2005 National Health Interview Survey (NHIS). PSA screening was defined as a PSA test as part of a routine exam within the past year. Demographic, socioeconomic, and functional characteristics were collected, and a validated 5-year estimated life expectancy was calculated. Age-specific rates of PSA screening were determined, and sampling weight-adjusted multivariate regressions were fitted to determine predictors of screening among men age 70 years or older. Results The PSA screening rate was 24.0% in men age 50 to 54 years, and it increased steadily with age until a peak of 45.5% among age 70 to 74 years. Screening rates then gradually declined by age, and 24.6% of men age 85 years or older reported being screened. Among men age 70 years or older, screening rates varied by estimated 5-year life expectancy: rates were 47.3% in men with high life expectancies (≤ 15% probability of 5-year mortality), 39.2% in men with intermediate life expectancies (16% to 48% probability), and 30.7% in men with low life expectancies (> 48% probability; P < .001). In multivariate analysis, estimated life expectancy and age remained independently associated with PSA screening (P < .001 for each). Conclusion Rates of PSA screening in the United States are associated with age and estimated life expectancy, but excessive PSA screening in elderly men with limited life expectancies remains a significant problem. The merits and limitations of PSA should be discussed with all patients considering prostate cancer screening.

Introduction: In 2014, the Canadian Task Force on Preventive Health Care (CTFPHC) recommended against routine prostate cancer screening with the prostate-specific antigen (PSA) blood test.1 We surveyed Canadian primary care physicians (PCPs) to understand their opinions and attitudes towards prostate cancer screening in 2016.Methods: Twenty PCPs piloted the survey to assess its accessibility. We distributed a flyer to 19 633 PCPs as an insert in a large mailed package inviting them to attend a national meeting, and later promoted the survey at the meeting. Multinomial logistic regression models examined factors associated with agreement of key guideline statements and the overall benefit of PSA screening.Results: A total of 1254 PCPs responded (rate of 6.4%); 54.7% of physicians aware of the CTFPHC recommendations report screening less often as a result. Overall, 55.6% of PCPs feel that the risks of PSA screening outweigh the benefits. On multivariable analysis, physicians who did not read the guidelines, did not have an academic appointment, or were in practice for over 20 years were significantly more likely to disagree with the statement that men 55‒69 years old should not be screened for prostate cancer with PSA.Conclusions: Our national survey found that the prostate cancer screening practices of Canadian PCPs varies widely across physician demographic groups, with almost equal numbers for or against. This has significant ethical, medical, and legal implications. The poor response rate to highly incentivized survey request may suggest a reluctance or general apathy towards this subject because of the Task Force recommendations. Future efforts should provide physicians with objective guidance around PSA screening, incorporating input from all stakeholders, including PCPs, urologists, and patients.

18 Background: In 2012, the United States Preventive Services Task Force (USPSTF) recommended against Prostate-Specific Antigen (PSA) screening, despite evidence that Black men are at a higher risk of prostate cancer-specific mortality (PCSM). We evaluated whether Black men of potentially screening-eligible age (55-69) are at a disproportionally high risk of poor outcomes. Methods: The SEER database was used to study 390,259 men diagnosed with prostate cancer in the United States between 2004-2011. Multivariable logistic regression modeled the association between Black race and stage of presentation, while Fine-Gray competing risks regression modeled the association between Black race and PCSM, both as a function of screening eligibility (age 55-69 vs not). Results: Black men were more likely to present with metastatic disease (adjusted odds ratio [AOR] 1.65; 1.58-1.72; P< 0.001) and were at a higher risk of PCSM (adjusted hazard ratio [AHR] 1.36; 1.27-1.46; P< 0.001) compared to Non-Black men. There were significant interactions between race and PSA-screening eligibility such that Black patients experienced more disproportionate rates of metastatic disease (AOR 1.76; 1.65-1.87 vs. 1.55; 1.47-1.65; Pinteraction< 0.001) and PCSM (AHR 1.53; 1.37-1.70 vs. 1.25; 1.14-1.37; Pinteraction= 0.01) in the potentially PSA-screening eligible group than in the group not eligible for screening. Conclusions: Racial disparities in prostate cancer outcome among Black men in are significantly worse in PSA-screening eligible populations. These results raise the possibility that Black men could be disproportionately impacted by recommendations to end PSA screening in the United States and suggest that Black race should inform clinical decisions on PSA screening.
