What you lot demand to know

• PSA testing has increased the number of men diagnosed with and treated for prostate cancer, but many of these men would never accept experienced any symptoms or death from prostate cancer

• This guideline makes a weak recommendation against offer systematic PSA screening based on an updated systematic review. The recommendation is weak because there may exist a modest, though uncertain, benefit of screening on prostate cancer mortality

• Men who place more than value on fugitive complications from biopsies and cancer treatment are likely to decline screening. In contrast, men who put more value in even a minor reduction of prostate cancer bloodshed (such as men at high baseline risk because of family history or African descent, or those concerned to dominion out the diagnosis) may opt for screening

• Shared decision making is needed for men considering screening to brand a conclusion consistent with their individual values and preferences. However, clinicians need not feel obligated to systematically enhance the outcome of PSA screening with their patients

What is the role of prostate-specific antigen (PSA) screening in prostate cancer? An expert panel produced these recommendations based on a linked systematic review.1 The review was triggered past a large scale, cluster randomised trial on PSA screening in men without a previous diagnosis of prostate cancer published in 2022 (box ane).ii Information technology establish no difference between former PSA screening and standard practice in prostate cancer mortality but found an increase in the detection of low run a risk prostate cancer after a median follow-upward of 10 years.

Box 1

Results of the CAP Randomized Clinical Trial2

This cluster-randomised trial of 419 582 British men was published in March 2022. Later on a median follow-upward of 10 years, there was no pregnant departure in prostate cancer-specific mortality in men receiving care by general practices randomised to a unmarried PSA screening intervention compared with men receiving care by practices randomised to standard exercise without screening. The detection of low risk prostate cancer cases was higher in the PSA screening grouping. Although the trial had limitations, such as low adherence to PSA testing in the intervention arm (36%) and a follow-up of only ten years, its findings do not support the use of unmarried PSA testing for population based screening.

The Rapid Recommendations executive felt this new report—taken together with extended follow-upwards information from existing trials—required a new appraisal of the body of prove for patients and clinicians.

Render TO TEXT

Although the results of this written report advise screening is not worthwhile, several guidelines advocate offer screening in some cases. The study was much larger than previous studies, and existing trials had published more than extended follow-upwards results, and the BMJ Rapid Recommendations squad felt these merited a new appraisement of the body of evidence. This guideline aims to promptly and transparently translate potentially practice-changing evidence to usable recommendations for clinicians and patients, based on the Course framework and following standards for trustworthy guidelines.

The panel suggests against systematic PSA screening (weak recommendation). The panel members judged that most men will decline screening considering the benefit is modest and uncertain and there are clear harms. However, there is likely considerable variation in values and preferences. Men with family unit history of prostate cancer, African descent or of lower socioeconomic status, having college baseline risk of prostate cancer death, may be more likely to cull PSA screening. Shared decision making is needed for men considering screening.

Current practice

Prostate cancer is one of the most common cancers in men and is the leading crusade of cancer death in 24 countries, ranking eighth globally, sixth in loftier income countries, and 12th in low income countries.three Prostate cancer screening is with a PSA blood examination. A raised PSA level tin be a sign of prostate cancer but tin can also occur due to a non-cancerous enlargement or inflammation of the prostate.4 Many men have a raised PSA level without having cancer (that is, imitation positive results). Conversely, a substantial number of men with a low PSA level will subsequently be diagnosed with prostate cancer (faux negative results).

Investigations later raised PSA

If PSA is raised, the examination is usually repeated. Men with persistently elevated PSA levels typically undergo a transrectal, ultrasound-guided, cadre-needle biopsy of the prostate to test for prostate cancer (run across chief infographic). If cancer is detected in the biopsied tissue, management options include surgery, radiation therapy, hormonal treatment, active surveillance, or watchful waiting. Diagnostic imaging studies such equally ultrasonography, magnetic resonance imaging (MRI), bone scan, and computed tomography, are often also performed, specially in men presenting with college risk illness, to bank check for disease spread.

Screening controversy

For many reasons, PSA screening remains controversial. Advocates often base their opinions on the European Randomised written report of Screening for Prostate Cancer (ERSPC), which suggests that screening may reduce the long term risk of prostate cancer-specific mortality by at to the lowest degree 9% (relative reduction).5 They also note that substantial observational evidence indicates a reduction in advanced illness and reduction in prostate cancer mortality, which they aspect to the introduction of PSA screening.6 Opponents of PSA screening highlight the indolent natural course of prostate cancer, citing systematic reviews that reported niggling or no impact of PSA screening on overall and prostate cancer-specific mortality.vii Opponents too suggest that the harms and burden from overdiagnosis and overtreatment resulting in unnecessary prostate biopsies and impaired urinary, sexual, and bowel function as side furnishings of surgery or radiation therapy outweigh the uncertain and pocket-size benefits.

Current guidelines on PSA testing

Guidelines vary in their recommendations on PSA testing (come across table one). The Canadian Task Strength on Preventive Health Care recommends confronting PSA screening for men anile 55 to 69 years.8 However, the United states of america Preventive Services Job Forcefulness recently changed its guidance to say that "the decision about whether to be screened for prostate cancer should be an individual one," without conspicuously suggesting for or against screening9: previously it recommended against screening in that grouping. National Cancer Center Network (NCCN) guidelines (which represents cancer centres in the USA) recommends initiating PSA screening at age 45 years.10 Guidelines from the American Urological Association (AUA)11 and European Association of Urology (EAU)12 recommend a discussion about PSA screening with patients.

Major guideline recommendations on PSA screening*

Uptake of PSA testing

The incidence of prostate cancer has dramatically increased over the final quarter century. This has been associated with widespread use of prostate specific antigen (PSA) testing detecting early stage prostate cancers.xiii There is broad variation in the adoption of prostate cancer screening. In the Britain, about 39% of men aged 45-69 years have undergone PSA testing in the past ten years.xiv In Sweden 23% of men anile 50-69 had a PSA test in the previous 12 months and 58% in the previous x years.15 Although the rates of screening have declined during the by decade in the United states,161718 upwardly to half of US men aged 60-74 undergo screening each year. Also, as many as 33% of elderly US men with competing medical comorbidities at high chance of dying from other cause underwent screening, and twice as many of these men recalled discussing the potential benefits rather than harms of screening.nineteen African-Americans were less likely to have been screened than not-African US men.20 Overall, two thirds of men reported no past discussion with physicians about the advantages, disadvantages, or scientific uncertainty and no shared decision making about prostate cancer screening.twenty

How this recommendation was created

Our international console included patient partners (men at risk of prostate cancer), general practitioners, general internists, urologists, epidemiologists, methodologists, and statisticians. They determined the scope of the question that the recommendation should address and what outcomes are most important to patients considering screening.

No person had financial conflicts of interest; intellectual and professional conflicts were minimised and managed (see appendix 1 on bmj.com).

The panel identified eight critical outcomes needed to inform the recommendations: all-cause mortality; prostate cancer bloodshed; incidence of prostate cancer diagnoses (all stages); incidence of localised cancer (phase I and Ii); incidence of avant-garde cancer (phase III and Four); complications from biopsies (such as bleeding, hurting, infections, and infirmary readmissions), complications from prostate cancer treatment (such as urinary incontinence and erectile dysfunction); and quality of life. The panel likewise identified 3 boosted patient-important outcomes: faux positive rates (men with elevated PSA levels who will have negative biopsy); fake negative rates (men with a normal PSA result who will afterwards be diagnosed with cancer), and the anxiety and uncertainty related to concerns about having prostate cancer. The panel asked that potential subgroups effects exist explored co-ordinate to age, screening interval, family history, being of African descent, and being of lower socioeconomic level. They too asked for a sensitivity analysis of the event of screening restricted to trials at lower gamble of bias.

To inform the recommendation, the panel members requested 2 systematic reviews, on the following questions:

• What are the benefits and harms of PSA screening versus no screening?i

• What evidence describes the values and preference of men considering PSA screening?29

Two parallel teams conducted these systematic reviews, which are linked to this publication.

The panel met to discuss the testify and formulate a recommendation. They followed the BMJ Rapid Recommendations procedures for creating a trustworthy recommendation,43 including use of the Form approach to interpret the evidence and create recommendations (encounter appendix 2 on bmj.com).44 The console considered the balance of benefits, harms, and burdens of PSA screening; the quality of the evidence for each upshot; and typical and expected variations in patient values and preferences, equally well as feasibility and acceptability. Recommendations can be potent or weak, for or against a form of action. The recommendations take a patient centred perspective which de-emphasises public health, societal, and health payer point of view.

The testify

The updated systematic review on the benefits and harms of PSA screening pools data from five randomised controlled trials (with ERSPC comprising 8 European countries), which enrolled a full of 721 718 men (with 419 582 included in the latest CAP trial).one

Chief characteristics and limitations of the trials

Effigy 2 provides an overview of the trials' characteristics and the patients included. All trials had methodological limitations. In the CAP trial merely 36% of men randomised to the screening arm actually underwent PSA testing (that is, low adherence to screening), while about x-15% in the non-screening arm were actually tested (that is, contamination). CAP too differed from other big calibration trials in that it used i-time screening, whereas others used repeated screening with intervals varying from almanac to every two years or more.

The Prostate, Lung, Colorectal and Ovarian (PLCO) Cancer Screening trial conducted in the US21 lacked allocation concealment, and rates of PSA testing in the not-screening arm exceeded 50%, possibly equally high as 80%.22

The European Randomised Study of Screening for Prostate Cancer (ERSPC) was conducted in viii European countries.5 There was possibly inadequate allocation darkening, and there are concerns that groups may have received different quality of treatment for prostate cancer (performance bias). Even so, the systematic review authors judged the ERSPC trial to be the ane that was probably least affected by bias. Based on a predefined sensitivity assay,ane the BMJ Rapid Recommendations panel decided to appraise both the summary of the whole body of show as well as selected information at lower risk of bias from the ERSPC study (encounter main infographic).

Although most studies reported mortality and cancer incidence, there was express randomised data on complications from biopsies or subsequent prostate cancer treatment and on quality of life. The systematic review team therefore searched for available follow-up evidence from the intervention arms of included trials and follow-up publications.

They used ERSPC sub-information for quality of life (that is, the Finnish arm of the report)23 and faux positive rates.24 They estimated simulated negative rates among men with a low PSA level from a follow-upwardly accomplice study of the Prostate Cancer Prevention Trial.25 Complications rates from subsequent treatment modalities were obtained from the ProtecT trial embedded in the CAP trial—in which patients diagnosed with prostate cancer in the CAP screening trial were randomised to active monitoring, radical prostatectomy, or radical radiotherapy with hormones.26 Similarly, complication rates from biopsies were obtained from the Prostate Biopsy Effects accomplice study nested inside the ProtecT trial.27 By modelling the likelihood of elevated PSA values, biopsies, cancer diagnoses, and handling modalities (from the NIH's Surveillance, Epidemiology, and Terminate Results (SEER) programme),28 the linked systematic review estimated the absolute number of biopsy and treatment related complications among men who underwent screening versus those who did not (see infographic and appendix 3 on bmj.com for more details). The quality of bear witness cess with GRADE considers the unique limitations in the evidence for each outcome.

Testify on men's values and preferences

Evidence suggests that unlike men approximate the benefits and harms of PSA testing and its consequences differently. The linked systematic review on the values and preferences of men considering PSA screening29 included studies that reported quantitative information on the degree of benefits (such as reduction in mortality risk) that men would require and degree of harms (such as increase in risk of incontinence) that men would be willing to accept to undergo prostate cancer screening. V studies were identified that investigated a direct choice related to PSA screening.29

The studies used different methodologies and varied considerably in how their outcomes were reported. One study showed that men were willing to forego screening with a benefit of 2% on prostate cancer mortality if information technology increases their probability of avoiding unnecessary biopsies by 10% or avoiding unnecessary treatment by ten%.thirty In another study, men were willing to accept between 65 and 233 per x 000 unnecessary biopsies to avoid one per x 000 prostate cancer deaths. These results varied with age: men in their 50s were willing to accept more unnecessary biopsies than men in their 40s or in their 60s.31

The review also included six studies in which men were presented with conclusion aids showing outcomes such every bit prostate cancer diagnosis and prostate cancer mortality. Willingness to undergo screening varied from 37% in a study displaying a reduction in mortality of 10 per 1000 men to 44% in a study displaying a reduction in bloodshed of 7 per 1000.29 The review found no studies that specifically investigated whether the men'south values and preferences differed among men with a family unit history of prostate cancer, men of African descent, or men of lower socioeconomic class.

Understanding the recommendation

The recommendation against PSA screening is weak because of the small and uncertain benefits of screening on prostate cancer bloodshed and the large variability in men's values and preferences. In do, a weak recommendation means that shared decision making is important. Clinicians should support men because screening to make a well informed decision in line with their ain risk profile and private values and preferences. Another implication of our weak recommendation is that clinicians practice not need to enhance the event systematically with their patients. They could raise PSA screening or wait for the patient to raise the issue. Both approaches are reasonable. It depends on the patient's context and competing issues in each clinical encounter.

The console believes that about informed men considering screening would decline it, although some would choose to undergo screening, accepting the diagnostic and therapeutic burden and harms that can outcome.

Absolute benefits and harms

The principal infographic explains the recommendation and provides an overview of the absolute benefits and harms of screening at a x twelvemonth time horizon for consistency and easier advice. Still, the individual trials varied in their elapsing of follow-up from 10 to 20 years (fig two), and we used the relative estimates of upshot, pooled in the linked systematic review, at the longest available follow-up fourth dimension.1 For the 10 year fourth dimension horizon, we used equally baseline risk in the not-screening arm of the CAP trial. Information technology provided the most contemporary estimates of risks from a large sample of men representative of a general practice setting.2

Death and cancer diagnosis

PSA screening may increase the detection of prostate cancer (seven more per 1000 men (95% confidence interval i to 15 more than) at x years), peculiarly of localised cancer (seven more per one thousand men (2 to xv more than)). But the information show no divergence in prostate cancer mortality. Overall confidence in these estimates across these outcomes was low because of risk of bias as well as the inconsistency of findings across studies.

• When focusing on studies at lower risk of bias—ERSPC trials—the panel was confident that over a 10 year flow:

  • PSA screening probably has footling or no result on death

    • All-cause mortality (0 fewer per 1000 men (95% CI iii fewer to 3 more))

    • Prostate cancer mortality (1 fewer per 1000 (1 to 0 fewer))

    • Prostate cancer mortality is similar at longer periods of up to xviii years of follow-up (1 to ii fewer per 1000 men)ane

  • PSA screening probably increases diagnosis of prostate cancer

    • Detection of whatever prostate cancer (18 more per thou men (16 to 20 more than))

    • Detection of localised cancer (14 more per 1000 (thirteen to xvi more))

    • Simply information technology probably results in a small decrease in detection advanced prostate cancer (iii fewer per yard (4 to two fewer)).

• The panel was too confident that:

  • About ii thirds of men offered a biopsy because of an elevated PSA result will have normal biopsy results and no prostate cancer (that is, false positive results of PSA screening)

  • About 15% of men with a normal PSA result will subsequently exist diagnosed with prostate cancer; with about 2% of men with a normal PSA result diagnosed with advanced cancer (that is, false negative results of PSA screening)

  • Each biopsy bears a substantial risk of side effects and serious complications, including blood in semen (93%), claret in urine (66%), pain (44%), fever (xviii%), and admission to hospital for sepsis (1-2%).

• Thus, considering that about one in seven men who undergo PSA screening will have an elevated PSA result25 and most of them will undergo biopsy (virtually 85% in the CAP and ERSPC trials, see appendix 3 on bmj.com):

  • Among a hypothetical population of 1000 men, about 94 more will nowadays with blood in the semen with PSA screening, 67 more with blood in the urine, 45 more with hurting, 19 more than with fever, and one more hospitalised for sepsis, due to a prostate biopsy

  • The panel acknowledges uncertainty in these projected estimates, as they were based on modelling and several assumptions in the rates of biopsies and cancers detected in men that were screened and in those who were not. These are likely to vary beyond clinical contexts and diagnostic strategies. For example, new approaches (including genetic or biomarkers, risk stratification tools, and MRI guided biopsy323334) have the potential for avoiding biopsies in men with not-progressive and slowly progressive cancer, and thus diminish the likelihood of harm from their complications when entering screening through PSA testing. All the same, the impact of such modalities on patient-important outcomes remains uncertain.

Harms linked to management of prostate cancer

• The panel was confident in the complications rates reported for treatments of prostate cancer, in detail:

  • Urinary incontinence (pad use at 6 years afterward treatment) was present in 17% of men who had surgery, 4% who had radiotherapy, and 8% of men under active surveillance

  • Erections not firm enough for intercourse were nowadays in 83% of men who had surgery, 73% who had radiotherapy, and seventy% nether active surveillance.

• Thus,

  • Applying these numbers to a hypothetical grand men,28 virtually three more will nowadays with urinary incontinence (whatever pad utilize) and 25 more will have an erection not firm plenty for intercourse due to handling for prostate cancer diagnosed through PSA screening (see appendix 3). One time once again, the panel has depression conviction in these projected estimates, as they are based on several assumptions depending on the detail context and required data modelling. New diagnostic strategies could too shift the proportions of men who enter agile surveillance rather than radical surgery or radiotherapy.

Quality of life

• The panel was less confident about the affect of screening on the overall quality of life or the anxiety of having cancer:

  • There was no difference in quality of life between men who undergo PSA screening and those who do not. Just this comparison was available only in a subset of men from one of the trials (northward=1088, more than details through the MAGICapp within the main infographic).23

  • There is no randomised evidence comparing PSA screening with non-screening in regard to the feet related to a cancer diagnosis. A large accomplice study in Sweden amid 4.3 million men showed an increased risk of suicide (relative take chances two.6 (95% CI 2.one to 3.0)) and cardiovascular events (one.iii (1.iii to i.3)) during the first year afterward diagnosis.35 A Us cohort written report with 343 000 men showed no increased risk of suicide during the first yr afterwards the widespread employ of PSA screening (after 1993) but an increased run a risk of cardiovascular death during the beginning calendar month after diagnosis (adapted relative gamble 1.55 (1.3 to 1.8)).36 Thus it remains uncertain whether screening results in changes in anxiety about cancer.

Adapting the offering for men at college chance of prostate cancer and death

The linked systematic review did not detect a relative subgroup effect by age: the effects of screening are consistent across age strata.1 Age of men enrolling in the studies ranged from 45 to fourscore years, with nigh aged fifty-69 years. The panel believes the prove thus applies to men regardless of age. However, whatsoever possible benefit of screening is likely to become negligible as life expectancy decreases due to age or comorbidities.

There were no randomised data on whether screening efficacy differed in those with a family unit history of prostate cancer, men of African descent, or men from lower socioeconomic levels. It remains uncertain whether the relative effect of screening is similar to that in the general population. However, these factors are associated with higher incidence of prostate cancer and higher risk of prostate cancer death in observational studies, as well as in follow-up publications of the trials included in the linked review (Finnish3738 and Swiss39 artillery from the ERSPC trial and the PLCO trial40). Using evidence from these trials, we adjusted the baseline risk in our summary of findings, using the aforementioned studies at lower hazard of bias (that is, ERSPC information). In these studies, family unit history was assessed past self reporting in a questionnaire and defined positive if a man reported that his father or at least one brother had been diagnosed with prostate cancer.3739 For race or ethnicity, non-Hispanic black men were compared with not-Hispanic white men.40 Level of educational activity was used as a proxy for socioeconomic status, and men with primary pedagogy only were defined as having a depression level of education and men with secondary or third pedagogy defined as having high level of pedagogy.38

• For men of African descent, over a 10 year period:

  • The baseline risk of developing prostate cancer of any stage is probable higher than that of the general population (estimated at about 51 per thou men diagnosed), and PSA screening probably increases their detection of any phase cancer by a larger magnitude than in the full general population (29 more per yard men (95% CI 26 to 32 more))

  • Baseline risk of prostate cancer mortality is likely also college than in the full general population of men because screening (estimated at virtually 7 per 1000 men dying at 10 years). Yet, PSA screening had a like minor effect in reducing prostate cancer mortality in absolute terms (one fewer per thousand (ii to 1 fewer)).

• For men with family unit history, over a 10 year period:

  • As for men with African descent, the baseline run a risk of developing prostate cancer is likely higher than in the full general population (estimated at virtually 50 per 1000 men diagnosed with any stage prostate cancer; and about 25 per 1000 are localised cancers). PSA screening probably increases their detection of any phase cancer (29 more per thou (26 to 31 more)) as well as localised cancers (19 more than per 1000 (17 to 21 more than))

  • These baseline run a risk estimates are based on studies that divers family history as positive if a man reported that his father or at to the lowest degree i brother had been diagnosed with prostate cancer. These baseline risk estimates may increase with increasing number of relatives diagnosed with prostate cancer.41

• For men with lower level of education, over a ten year menses:

  • In that location was limited data on how much more these men were at higher baseline risk. Using lower level of instruction as a proxy of lower socioeconomic status,38 we estimated that baseline risk of prostate cancer bloodshed was college (about 4 per 1000 men dying at x years) too as all-cause mortality (almost 196 per thousand men)

  • The absolute effect of PSA screening is overall comparable to that in the other subgroups, with a modest reduction in prostate cancer mortality (most one fewer per 1000 men (1 to 0 fewer))

  • PSA screening probably has little or no outcome on all-crusade mortality (about iv fewer per 1000 (10 to 0 fewer)).

Values and preferences

The panel, including the patient partners, felt that this variability in values and preferences contributes to a weak recommendation. The recommendation against screening reflects a belief that well-nigh men would value avoiding complications from biopsies and subsequent handling because the reduction in prostate cancer and death from screening is pocket-size and uncertain. Prostate cancer will oftentimes, though not always, remain indolent.

Men who place a high value on avoiding complications from biopsies and subsequent treatment are likely to decline screening. In contrast, men who place a higher value on even a small-scale reduction of prostate cancer may opt for screening. Several panel members felt that higher adventure patients—such equally patients with family unit history of cancer or of African descent—may be more than likely to seek screening because they may worry more almost prostate cancer and want to rule out the diagnosis.

For men because screening, shared decision making is critical to ensure that their decision is in line with their own values and preferences. The testify summarised in this Rapid Recommendation is available in MAGICapp every bit decision aids that can support shared determination making (https://app.magicapp.org/public/guideline/n32gkL).

Applied issues and other considerations

Effigy iii outlines the key applied issues. PSA testing can be performed on any normal claret sample, but prostate biopsies and their follow-up have important implications for daily life.

Lower urinary tract symptoms (slow urine stream, sensation of incomplete emptying, increased urinary frequency) are mutual complaints in adult men that can have a major touch on quality of life. Beneficial prostatic enlargement is the major cause. Bear witness to date indicates that men with these complaints are not at increased risk of prostate cancer.iv

For men who chose to undergo PSA testing, the optimal frequency of screening remains unknown. Effigy 2 summarises the frequency used in the unlike trials, still the accompanying systematic review did not discover any significant subgroup event of the event of screening based on these different frequencies.i Given that the ERSPC data are probable at lower hazard of bias, PSA screening every 4 years—rather than, say, every yr or simply in one case in a lifetime—may be the optimal interval.

Costs and resources

Results from a recent cost-effectiveness study modelled for the US suggested that screening between the ages of 55 and 69 years combined with active surveillance for low risk men could only exist cost-effective at a $100 000 threshold if the screening frequency remains depression (every four years) and agile surveillance is offered to all men with depression run a risk prostate cancer (that is, Gleason score ≤6 and phase ≤T2a). Strategies with shorter screening intervals or in which immediate treatment is offered to all men were not cost-constructive.42 Although the Rapid Recommendations panel focused on the patients' priorities rather than those of society, our recommendation is compatible with these findings.

Uncertainties for time to come inquiry

Contempo show suggests that incorporating MRI in the investigation of those with a positive PSA examination result decreases the false positive charge per unit, and thus the number of patients undergoing unnecessary biopsies, and may also increase the accuracy of biopsies in those who exercise have prostate cancer. The Rapid Recommendations panel considered addressing this issue in the guideline, but the touch on of MRI on long term outcomes of prostate cancer incidence, bloodshed, and complications of treatment remains uncertain. Sophisticated decision modelling might shed calorie-free on this event, but the panel decided non to bear such an analysis because of logistic and feasibility considerations, and considering the panel's review of the evidence suggests that modelling would introduce further uncertainties regarding the touch on of MRI on patient-important outcomes.

Cardinal research question to inform decision makers and future guidelines include

• Could new screening and diagnostic techniques reduce the harms and burden of the diagnostic process by better identifying non-progressive and slowly progressive cancer from cancer that is probable to become symptomatic and bear upon quality or length of life? These strategies may include genetic markers or biomarkers, risk stratification tools, or MRI guided biopsy.32 For example, two recent high quality studies on MRI guided biopsy take shown encouraging results of MRI to reduce overdiagnosis,3334 but the affect of this strategy on long term, patient-of import outcomes (such every bit prostate cancer incidence, mortality, and complications of handling) remains uncertain.

• For men opting for screening, what would be the ideal age range and screening interval? Randomised trials varied in their offer of a one-off or repeated PSA testing and it remains uncertain which strategy is more suitable.

• What is the impact of screening on men at higher baseline risk (men with a family unit history of cancer, of African descent, and of lower socioeconomic status)? Are their values and preferences dissimilar from those of men in the full general population?

Updates to this article

The final table shows evidence that has emerged since the publication of this commodity. As new evidence is published, a grouping will assess the new testify and make a judgment on the extent it is expected to alter the recommendation.

New evidence which has emerged after initial publication

Education into practise

• To whom exercise you consider offering PSA screening for prostate cancer? Is this article probable to modify your practice?

• How do you explain potential benefits and harms from PSA screening to men in your consultation? How can this commodity help you discuss these outcomes?

• How can you support patients to make a decision nearly PSA screening according to their values and preferences?

How patients were involved in the creation of this article:

Three men eligible for PSA screening were full console members. They identified important outcomes and led the discussion on values and preferences. They fully participated in the teleconferences and email discussions on the evidence and the recommendation. They also contributed to the identification of practical issues related to the decision to undergo PSA screening, and met all authorship criteria for the present article.
