Not yet??
Quoting the article:
"Randomized controlled trials have not yet shown that early detection of prostate cancer with PSA testing does more harm than good, but many feel that the 4% annual decline in prostate cancer mortality rate in the United States over the past decade must be attributable to PSA screening, though improvements in treatment, including more widespread use of androgen deprivation for advanced cancer, may explain some of this trend. "
IMO there are problems with this sentence.
-- It is too long; a full stop after "than good" would be appropriate I think. (Perhaps also one after "improvements in treatment".)
-- The part about more harm than good is without context. There is no prior mention of the idea that early detection may "do harm" and no explanation of why it might.
-- The word "yet" implies a belief that it will eventually be shown that 'early detection does harm', a highly speculative notion IMO.
I realize some of these points are likely covered in other articles but I think this article should be better able to stand on its own. Wanderer57 (talk) 20:35, 26 August 2008 (UTC)
Medical malpractice and PSA
Here's a good free link to the Merenstein article on how doctors can lose a medical malpractice case for not giving PSA tests:

- OMG that is ridiculous. The poor man. But then I guess that is what happens when you leave these things to juries to decide. The deceased also deserves some sympathy but it is not all clear that his outcome would have been much changed by an earlier PSA test. Sadly surving life is a matter of negotiating a mass of statistical probability hurdles. Crossing the road has risks and benefits. The exceptions are always exceptions and one should not be led into thinking that the exceptions make the rule. As I understand American urological professional guidance, the doctor did what his profession guides him to do. This is similar to guidance in the UK http://www.patient.co.uk/pdf/pilsL493.pdf which is there to enable the patient to make the decision for himself. They don't insist on getting the patient to sign that they have received the advice, but even in this case it would not have helped the poor Dr. given that 4 other Drs. were prepared to testify that they wouldn't have even give the patient the choice of having the test. Amazing, but sad and instructive.--Hauskalainen (talk) 01:11, 24 October 2009 (UTC)
paragraph about medications that lower PSA levels
Created separate paragraph about medications that lower PSA levels, adding info that finasteride cuts levels in half) (both doses) and mention the clinicial implications (must adjust reference ranges and velocity of change calculations accordingly) Leave brand name marketing information to linked Finasteride and Duasteride articles.
If someone has time to update more, suggested range tops out at 2.0 instead of 4.0 in patients taking finasteride, rate calculations go to a change of .3 per year instead of .7.
Is cost-benefit analysis to date missing the point?
"1410 men would need to be screened and 48 additional cases of prostate cancer would need to be treated to prevent just one death from prostate cancer.[5]" (article)
At a glance, it appears that all 48 men with prostate cancer would need aggressive treatment to prevent one death. This overlooks that many such patients will be offered, and choose, active surveillance and proven prevention methods (see next discussion section).
The with highest scores, may indeed be recommended to, and receive, more invasive intervention -- and should be. But the benefits for the group with highest-risk cancers in preventing death and disability are highest. More of this highest-risk cancer group will choose aggressive intervention precisely because they quite rightly conclude that they likely have a curable prostate cancer that is of concern for metastasis if treatment is delayed.
If active surveillance plus proven risk-reduction methods are suggested to many of the lower-risk patients among the 48 identified cancer cases, then many of them will never be subjected to invasive interventional methods.
The usual cost-benefit analysis seems to be based on the idea that the costs side for all 48 men includes intervention more invasive than active surveillance and prevention methods, which may not be the case.
Some benefits of PSA testing have been overlooked.
Peace-of-mind and patient-education benefits of PSA testing for the men with low scores may also have been given short shrift. In the first European study cited by the article, most of the 1410 men tested may worry less after learning they do not have prostate cancer. At the same time, the testing provides their physicians an opportunity to provide valuable education about BPH progression, and to counsel them about available prevention measures. These benefits to the men who do not have cancer identified by PSA testing have been overlooked.
The costs to men who learn through PSA testing that they have prostate cancer may have also been overstated or exaggerated. Such men may be offered, or elect, active surveillance (formerly "watchful waiting") plus proven prevention methods. This will allow many of them to avoid unneeded treatment while those who do need invasive interventional treatment secure it when events develop to show that it is needed. An accurate cost-benefit analysis must figure the costs of invasive testing of the smaller group that actually selects invasive intervention only. Meaningful weighing of the costs against the benefits requires not exaggerating the costs.
Effective, non-invasive risk-reduction measures are available for most men revealed by routine PSA screening to have prostate cancer.
These methods are available to all men, even those who have not yet developed prostate cancer, but are especially salient to those in whom prostate cancer is identified (now, often via a PSA screening):
1. Regular use of Finasteride has been shown to reduce the rate of invasive prostate cancer (and all cancers) by 30% in well-conducted trials.
2. Learning one is at higher prostate cancer risk may provide additional reason to correct use/abuse of anabolic steroids, testosterone, or androgenic precursors, or to lower high BMI, and to quit smoking.
3. A study by Ornish et al. found that prostate cancer markers were affected by a low-fat diet that included small amounts of fish, combined with exercise, stress-reduction, and counseling. Learning that one's PSA level is in a range that corresponds to higher risks may increase motivation to pursue one or more of these interventions, which may result in improved health and lower all-cause mortality and morbidity.
4. NSAID use may reduce metastisis.
5. Men revealed by a screening test to have low-grade prostate cancer, or simply an elevated PSA, may also be counseled about the effective long-term management of BPH, including drugs such as finasteride and dutasteride which may stop the progress of overgrowth before symptoms emerge that may later affect quality of life, as well as the other lifestyle changes mentioned above.
Overlooked patient counseling opportunities, not cancer screening, must take any blame for over-treatment in connection with PSA screening
If only the higher-risk of the 48 are treated with aggressive intervention, the rate of lives saved per intervention will be much higher.
The missed opportunities to counsel men with higher PSA test results on non-invasive active surveillance and proven risk-reduction measures is to be faulted -- not administration of the PSA and other screening measures such as DRE. Such screening provides a teachable moment about the advisability of measures which reduce risks of both prostate cancer and advanced BPH.
As an example of overlooked medical counseling, how many men with high PSA levels have been advised that extreme PSA can eventually result in inability to urinate and, if unattended to, even kidney failure?

Obesity in screening prostate cancer risks -- Hazard Ratio 2.66 compared with healthy-weight men
- "... Compared with men of a healthy weight (BMI <25 kg/m(2)) at baseline, overweight men and obese men had a significantly higher risk of prostate cancer mortality (proportional hazard ratio [HR] 1.47 [95% CI 1.16-1.88] for overweight men and 2.66 [1.62-4.39] for obese men; p(trend)<0.0001). ..."
- "... BMI was an independent predictor of higher Gleason grade cancer (P <.001) and was associated with a higher risk of biochemical recurrence (P =.027). ...
- "... BMI was positively associated with prostate cancer mortality—the higher the BMI, the greater the risk of death. Men with a BMI of 35 or greater had more than two times the risk of dying than normal-weight men.
- In addition, weight gain during adulthood also significantly raised the mortality risk from prostate cancer. As with BMI, the risk of death increased as the amount of weight gain increased.
- The study sheds light on yet another potential benefit of maintaining a healthy weight, especially since prostate cancer is a common cancer among American men.

issues with this article
I have made a few changes here today - the lead section is really quite POV. I think someone has mistaken generalised prostate cancer screening with a specific type of prostate cancer screening - i.e. the PSA test. Don't confuse the two - just because PSA has not proven successful it doesn't mean prostate cancer screening per se is potentially detrimental. This article still needs a lot of work - what about screening methods other than PSA and DRE? Cheers, --Amaher (talk) 02:15, 16 March 2010 (UTC)

Clinical practice guidelines section is huge
The 'Clinical practice guidelines' section is large and repetative eg it discusses the ACS guidelines twice at length. Perhaps the blockquote should be deleted ? - Rod57 (talk) 02:20, 3 November 2011 (UTC)
"Hyperbole?"
This article needs a lot of work. My recent edit was completely reverted without any explanation - other than calling it "hyperbole" in the edit summary. 1st - I edited: "This recommendation has been criticized by many prostate cancer experts for a number of reasons, most important among which is its over-reliance on findings from the deeply flawed U.S. Prostate, Lung, Colon, and Ovarian screening trial to make it more neutral. The "deeply flawed" is not in the cited source - which is the original paper on the trial. Clearly inappropriate.
I also put in half a sentence on why the test is considered controversial following: "The test is controversial". The reverter says the material I added is already in the article (yes but at the very bottom of an overly long article), and that the material is hyperbole (complete nonsense - if the test is controversial, it should be explained why).
The material I added is generally supported by the new official recommendation of the U.S. Preventive Services Task Force. See e.g. Prostate Cancer Test Gets a Failing Grade. This material needs to be included, not trashed with completely unsourced nonsense like "deeply flawed."
BTW - before you ask me to comment on the talk page, it would be appropriate to explain yourself on the talk page first.
Smallbones (talk) 12:20, 22 May 2012 (UTC)
- It looks to me that there may be misunderstanding in this little discussion (here and in edit summaries). Perhaps both editors, Smallbones & UncleBubba, will take a second look.
- Smallbones: I may be wrong but I don't think the mention of hyperbole referred to your edit of the para starting "Prostate test screening is controversial ........."
- The sentence you modified,
- FROM "Prostate test screening is controversial."
- TO "Prostate test screening is controversial because of it low effectiveness in reducing deaths, the side effects resulting from over-diagnosis from the tests, including impotence, incontinence, and bowel disorders, and its high costs.",
- seems to me to pack too much information into one sentence. However I sympathize with your desire to have a succinct statement on the controversy early in the article. Wanderer57 (talk) 18:37, 22 May 2012 (UTC)
- Feel free to re-write, but, correct me if I'm wrong, those are the reasons that screening is controversial. If so, they need to be included right near the top - preferably right after the word "controversial." The new material from the U.S. Preventive Services Task Force (link above) also needs to be included. The official position needs to be clearly spelled out before it is criticized, and that should not be controversial. Smallbones (talk) 22:02, 22 May 2012 (UTC)
While it's apparent your edit was well-intended, inserting terms like impotence, incontinence, bowel disorders, etc. into the lede of the article looks too sensational.
The source is an op-ed piece discussing a current controversy, and there is disagreement within the medical community regarding the efficacy and wisdom of PSA screening. I wouldn't oppose a more balanced and neutral-sounding summation here, but in-depth discussion of the controversy should be placed in its own section within the body of the article, not in the lede.
My overriding concern is that a great many people use Wikipedia to gather information, and some of this information will be used to make life-affecting choices. As such, we editors have a responsibility to present information accurately, clearly, and coherently, in a balanced and impartial manner.
I did not intend to step on your toes, but I feel we need some consensus before this text is added to the article. As such, I'm removing it. I hope you will, in the spirit of WP:BRD discuss it with me (and any other interested persons) here before taking further action.
Thank you. — UncleBubba ( T @ C ) 04:21, 23 May 2012 (UTC)
- The material I've just put in is an explanation of the official US government position - it needs to be near the top - it is the predominate scientific position - both in the US and in Europe. Using words like "impotence" and "incontinence" may be a bit frightening - but that is what the problem with the test is all about. Using the word "cancer" is also frightening - but we can't discuss the material without these words. Smallbones (talk) 00:44, 29 May 2012 (UTC)
--- I think it would be better for this article if you did not insist quite so vigorously on your point of view. As suggested above, discussion is called for.
Why do I say this?
- What we now have is a lead section which is confusing because of its on-the-one-hand, on-the-other-hand nature. Perhaps not confusing to a person well familiar with the whole controversy but certainly so to most laymen.
- Your reasoning relies heavily on the official US government position. Bear in mind that Wikipedia is intended for an international audience. The information I have heard from non-US sources is that the US anti-testing approach is conditioned by the US approach to aggressive treatment of prostate cancers when they are detected, and that a more measured approach to treatment would have resulted in less of the seriously negative consequences you warn about.
My point in mentioning these issues is not to say that you are wrong and somebody else is right. It is to try to advance the idea that prior discussion might be a more fruitful approach than unilateral edits. Wanderer57 (talk) 05:03, 29 May 2012 (UTC)
- Please clean up the rest of the article before you complain that the predominant scientific position is out of place. Have you noticed that most material is repeated twice (before my edits), but that the predominant scientific position is mentioned only in a few phrases at the bottom of the article? Also the "unilateral edits" that I've seen are just reversions of what I've written. The anti-testing position is similar in Europe as well as in America. Please don't try to minimize the lack of balance in the article before I edited it - there was almost no mention of the predominant scientific position, and it needs to be stated up front. Smallbones (talk) 05:30, 29 May 2012 (UTC)
- Thank you. I am not going to review the history of this article to form an opinion whether it was better or worse before your edits. It may well have been improved by them.
- My comments above were about the state of the article at the time of the comments.
- I will take a look at the article as it now stands after your recent edits. Wanderer57 (talk) 15:15, 29 May 2012 (UTC)
specialty society guidelines
the lead paragraph now reads like a list of the different guidelines, rather than a summary of the subject, but my attempt to collapse the other guidelines to avoid this was not well-received. suggestions? -- [ UseTheCommandLine ~/talk ] # _ 18:33, 5 April 2013 (UTC)
- Further, more than half of the lead paragraph is taken up by a discussion not of prostate cancer screening per se, but PSA screening in particular, which is inappropriate. -- [ UseTheCommandLine ~/talk ] # _ 18:34, 5 April 2013 (UTC)
First of all, prostate cancer screening is about PSA screening -- DRE-based screening is virtually (not yet entirely) irrelevant in 2013. The simple fact is that the USPSTF is not the definitive guideline. It is not better, not more reliable, and no more evidence based than the others. There is no justification for giving it more attention. You obviously feel that specialists are less trustworthy that primary care providers on this question, but that it just your opinion. Personally, I think it would be much better to simply present the evidence for and against screening and save the guidelines for the end. As I keep saying, this is a two-sided debate, and both sides must be given equal voice. — Preceding unsigned comment added by Drcoop (talk • contribs) 18:42, 5 April 2013 (UTC)
- Please don't make assertions, assumptions, or accusations about what I think or feel, that seems inconsistent with assuming good faith. -- [ UseTheCommandLine ~/talk ] # _ 18:52, 5 April 2013 (UTC)
- With all due respect, Drcoop, DRE-based screening is certainly not irrelevant, virtually or otherwise. Any changes to the article in this regard will require some significant sourcing. WP really isn't a forum for debate, nor is it an outlet for current event news. Your assertion that you know that another editor "obviously" feels a certain way is getting dangerously close to a personal attack. Let's discuss the article, not the editors--we're all on the same team here. — UncleBubba ( T @ C ) 21:08, 5 April 2013 (UTC)
Never suggested DRE should be removed from the article. Point was in response to the suggestion that too much time was being spent on PSA. I'm really not trying to debate, but these articles--both this one and the prostate cancer one--present the position that the answer on PSA screening is known and settled, when in fact it is not. I have met a great deal of resistance over the past couple of days trying to make this point clear, and am frustrated. Not intending anything personal.152.132.10.134 (talk) 21:45, 5 April 2013 (UTC)
- I think you may be misinterpreting things a bit. These articles obviously change from day to day and week to week as new evidence comes in. However, the practice as is common in biomedical literature of saying explicitly that "more research is clearly needed" or the like, is not a norm here. We summarize what is the best available, reliable evidence here, without doing our own original research. WP is not a forum for cutting edge research.
- The assertion that "There is no justification for giving [the USPSTF guidelines] more attention." also seems difficult to square with the fact that these guidelines help determine what bodies like CMS and the VA are willing to pay for, I suspect moreso than the opinions of specialty societies or the AMA (but that's maybe getting a little too WP:NOTFORUMish, i digress.) It also prompts me to wonder a bit about what the standard of care is in other countries, since this all seems to inordinately focus on the US.
- And your assertion that both (or all) sides must get equal treatment is plainly incompatible with WP's norms and policies, specifically the policy on undue weight. My reading of that policy would seem to suggest that the USPSTF guidelines should have an explicit mention in the lead para, and further that naming the other organizations who have released guidelines subsequently that challenge the USPSTF's in some way gives those guidelines undue weight. Certainly they should be mentioned in the body of the article, specifically in the context of secondary, RS coverage of them, but to have them sticking out in the lead para like they are right now seems undue. I think the substance of my initial attempt at compromise, corraling them as references for a statement about "Other guidelines" is reasonable, but I am open to other suggestions. -- [ UseTheCommandLine ~/talk ] # _ 22:39, 5 April 2013 (UTC)
Information about racial disparities in incidence and outcomes

Self-citation COI
I have a self-citation COI with RTI International, a non-profit contract research organization. They published a study in a peer reviewed journal about how many men were planning on getting prostate exams, despite advice not to. I was thinking this may be a useful addition to this article after the paragraph starting with "The United States Preventive Services Task Force (USPSTF) recommended against PSA screening in healthy men finding that the potential risks outweigh the potential benefits..." as the study was done in the context of the controversy related to this recommendation by the USPSTF.
I would propose something like:
- In July 2013, scientists from RTI International conducted an online survey of 1089 men that were 40-74 years old and had no history of prostate cancer. It found that 62% agreed with the recommendations by the United States Preventive Services Task Force to avoid prostate test, but only 13 percent planned to follow the recommendation and stop getting prostate exams. The study concluded that consumers were "favorably disposed to PSA testing, despite new evidence suggesting the that the harms outweigh the benefits."

- I am familiar with it, but not extensively, so I humbly accept your judgement on the issue. From what I've read, it seems we would prefer peer-reviewed journals that critically examine and summarize the available research as secondary sources. Since this study was just published in July, I would expect it to take some time before a source like that emerges. I have seen us use much weaker sources for medical claims (studies with only 80 participants, etc.), but such guidelines are complicated, which is why it's better for an editor with a COI to point out things that may be helpful, rather than edit, since I may construe the rules in a self-serving manner mistakenly.

- You are asking to add the information to the 'Controversy about Screening' section (not the lead paragraph). The medical claim in your request is "evidence suggesting the that the harms outweigh the benefits". Regarding, 3. people agreeing/disagreeing with 2. task force recommendation about 1. prostate cancer screening is two steps removed from the main topic, prostate cancer screening. As for 4. scientists from RTI International reporting 3. people agreeing/disagreeing with 2. task force recommendation about 1. prostate cancer screening is three steps removed from the main topic. Also, 5. RTI International opinion about 4. scientists from RTI International survey of 3. people agreeing/disagreeing with 2. task force recommendation about 1. prostate cancer screening is four steps removed from the main topic and is an opinion (study concluded that consumers were "favorably" to testing). The whole Controversy about Screening section does not make sense since it lacks structure/flow. The sub section is problematic in that it seems to be about "reaction", not "controversy": There have been a variety of reactions to the cost and long-term effect of screening patients for prostate cancer. That probably is not a sufficient description. We might be able to work in the two sources you list into the subsection, but cannot even consider how to do that without first rewriting the 'Controversy about Screening' section using the information already in the article so that the section makes sense. -- Jreferee (talk) 01:53, 18 August 2013 (UTC)
- I was asked for my opinion on this.
- We can use primary sources in medical articles, carefully.
- The proposed edit does not cover safety, efficacy or biological claims, just preliminary information about attitude, so this seems alright to me to include based on one good primary source, provided it's made clear that it is only one study, and the size of the study.
- Only cite the journal article, not the US News item
- As the information was collected November-December 2011, it's already a little old - for an attitude survey whose results will be affected by ongoing publicity and primary practitioner (GP) behaviour, so
- Do mention the period over which the data was collected.
- Don't mention RTI, it's not sufficiently relevant.
- Do mention the 33% undecided so you're reporting a clear picture of the results.
- Don't mention the authors' conclusions, just the results. Leave drawing conclusions to independent expert reviewers.
- It could be more concise.
- If there is consensus for inclusion, may I suggest something along these lines?
- In a November-December 2011 internet survey of 1089 men with no history of prostate cancer who had reviewed the USPSTF recommendation, although 62% agreed with the recommendation, only 13% intended to follow it and avoid the PSA test, while 54% intended to disregard it and planned to have a PSA test (the remainder were undecided).

Milking out the Screening Pro's and Con's
The entire article seems to go on an on and on ad nauseam on the pro's and con's of screening. There is a paragraph 'Controversy about screening'. Then the next paragraph, 'Clinical practice guidelines', again picks up about those pro's and con's. Meanwhile I couldn't find anything in here (not even a ref.) to PSA tests that are conducted when e.g. as part of a CT scan lung noduli are found, which lead to a blood test, part of which is a PSA test (becuase of the noduli, i.e. not a 'screening' test in that sense: there was a cause to test for PSA.

Redundancy, long-term projections based on ERSPC data.
Redundancy: Sections "Clinical practice guidelines" and "Research" (italic) contain quasi identical paragraphs, with only seven words difference (underlined):
- In the European Randomized Study of Screening for Prostate Cancer (ERSPC) initiated in the early 1990s, the intention was to evaluate the effect of screening with prostate-specific antigen (PSA) testing on death rates from prostate cancer. The trial involved 182,000 men between the ages of 50 and 74 years in seven European countries randomly assigned to a group that was offered PSA screening at an average of once every 4 years or to a control group that did not receive such screening. During a median follow-up of almost 9 years, the cumulative detected incidence of prostate cancer was 820 per 10,000 in the screening group and 480 per 10,000 in the control group. Deaths from these cancers in this time was much lower. There were 214 prostate cancer deaths in the screening group and 326 in the control group, a difference of 7.1 men per 10,000 in the tested group compared to the control. The researchers concluded that PSA-based screening did reduce the rate of death from prostate cancer by 20%, but that this was associated with a high risk of overdiagnosis, which means that 1410 men would need to be screened and 48 additional cases of prostate cancer would need to be treated to prevent just one death from prostate cancer within 9 years.
- In the European Randomized Study of Screening for Prostate Cancer (ERSPC) study initiated in the early 1990s, the intention was to evaluate the effect of screening with prostate-specific antigen (PSA) testing on death rates from prostate cancer. The trial involved 182,000 men between the ages of 50 and 74 years in seven European countries randomly assigned to a group that was offered PSA screening at an average of once every 4 years or to a control group that did not receive such screening. During a median follow-up of almost 9 years, the cumulative detected incidence of prostate cancer was 820 per 10,000 in the screening group and 480 per 10,000 in the control group. Deaths from these cancers in this time was much lower. There were 214 prostate cancer deaths in the screening group and 326 in the control group, a difference of 7.1 men per 10,000 in the tested group compared to the control. The researchers concluded that PSA-based screening did reduce the rate of death from prostate cancer by 20% but that this was associated with a high risk of overdiagnosis. Statistically, it means that 1410 men would need to be screened and 48 additional cases of prostate cancer would need to be treated to prevent just one death from prostate cancer.
Long-term projections based on ERSPC data:
- One recent analysis of the ERSPC data suggested that projecting over a 25-year time horizon, which is more appropriate for a man in his 50s than the 9 years reported to date from the trial, the number needed to screen falls to 186-220, and the number needed to treat to prevent a death falls to between 2 and 5 men.
Some important information is omitted here, namely that this is a projection for the US situation. Their projection for Europe (which the reader will assume since it is an analysis of a European study) is: 262 men need to be screened and 9 additional men need to be treated to prevent one prostate cancer death.

I found the above three articles by searching for reviews during the last five years, in core clinical journals only, with these key words: "Prostate-Specific Antigen/blood"[MAJR] AND "Mass Screening/methods"[MAJR]
(which should find only reviews that are primarily about the use of the PSA test specifically as a screening tool). Perhaps they would be useful for building an article that reflects the latest mainstream medical view on the PSA test. WhatamIdoing (talk) 00:34, 28 February 2018 (UTC)

Not addressed
Doc James, the issues I raise for example with this edit have not been addressed. This article prioritizes ONE guideline (an old one) over many others (why?), the lead does not sufficiently address the controversy, or mention that screening saves lives, and African Americans are not even mentioned in the lead. Stating that "two methods are used" (DRE and PSA) is completely useless info, since they are optimally used together, not separately.
And HOW on earth do we have an article on prostate CANCER screening where the NCCN guidelines are not even mentioned, best I can tell. The impression from this article is that screening is not done-- not that men are encouraged to discuss it with their doctor and make an informed decision, weighing risks and benefits.
Yes, there is controversy with poor use of PSA screening (because of men freaking out over a Gleason 6 and demanding treatment, for example, or demanding biopsies based on PSA only with no DRE findings), but nonetheless, you will find plenty of reliable medical sources acknowledging that screening saves lives, and that is not mentioned in the lead.
This is not an article that should be casually or quickly edited, because the incomplete and incorrect information it presents is dangerous. Unless the article is going to be fully corrected to reflect the complete nature of the issue and the controversy, please leave my warning at the top of the article so our readers can at least access an accurate article before they decide to ignore their doctor's recommendations, or go away with the impression that all screening is discouraged. Where in this article, and in the lead, is information that screening saves lives? The lead biases one side of the controversy, in a way that is dangerous to men's health.
What most of the guidelines share in common is that men should be able to make an informed decision. What Wikipedia says is pretty much that men should not be screened at all. Two different things. And in direct contradiction to NCCN. SandyGeorgia (Talk) 07:08, 18 February 2018 (UTC)
Gah
We have this "Potential benefits of screening stem from early detection; decreasing rates prostate-cancer specific mortality and metastatic disease, and increasing detection of localized cancers (better prognosis)."[1]
Ref however says "Only one of five randomized controlled trials of PSA screening showed an effect on prostate cancer-specific mortality, and the absolute reduction in deaths from prostate cancer was one per 781 men screened after 13 years of follow-up. None of the trials showed benefit in all-cause mortality, and screening increased prostate cancer diagnoses by about 60%. Harms of screening include adverse effects from prostate biopsy, overdiagnosis and overtreatment, and anxiety."
That is not an accurate summary of the source. Doc James (talk · contribs · email) 13:54, 2 March 2018 (UTC)

New testing trial in UK news (3 March 2018)
(I thought it best to put this in talk as there isn't a research section, and, given WP:NOTNEWS and WP:MEDPOP, I'm not sure if it's even appropriate to add this to the article?)
A new "one-stop" service for prostate cancer testing has made the UK news today. It's a 2 year study focused on performing mpMRI scans prior to a TRUS biopsy. The scan and any biopsy (if needed) would be done on the same day, or a relatively short time afterwards, with the MRI images being used to help target any relevant prostate lesions. (Stereotactic surgery?)
The story seems to have broken in Daily Mail; but per WP:DAILYMAIL, here are links for other sources: BBC and The Times (paywalled). Little pob (talk) 17:21, 3 March 2018 (UTC)
- We do not add medical news to Wikipedia; Wikipedia is not a newspaper. Thanks. Jytdog (talk) 17:28, 3 March 2018 (UTC)
- Thanks for confirming. Little pob (talk) 17:43, 3 March 2018 (UTC)
- (edit conflict) I see no usefulness in adding this information, NOTNEWS, and the source does meet MEDRS. (Besides that, the idea seems wacky ... I am aware of no reliable source or reputable practitioner claiming that six weeks delay matters in prostate cancer detection and treatment. Is the NHS that goofy?) And BBC, really? "Currently a test for men with prostate cancer requires an MRI scan and a biopsy where a dozen samples are taken, requiring multiple hospital visits." It does not require an MRI, and it does not require multiple visits, and in the US, it does not require a hospital visit. And the "dozen samples" happen in one biopsy. This kind of crappy laypress reporting is why we don't use the laypress. (Johnbod what on earth is the NHS thinking? They don't want PSA screening, but they will jump to a very expensive and unnecessary modality?) SandyGeorgia (Talk) 17:49, 3 March 2018 (UTC)
Biopsy section is incomplete
Techniques has? Missing hyphen? Biopsy may de done through the rectum, or the perineum, or the penis ... but this information is not very useful if not also mentioning that transrectal is by far the most common, and that biopsy is also typically ultrasound guided (this article implies that MRI guided is more common). MRI-guided biopsy is not covered by most insurance because it is not yet proven useful generally (at least that is what we were told anecdotally). Better research and sources needed. I am unaware of when the more rare biopsy is done through the penis or perineum, but it might help to flush that out. SandyGeorgia (Talk) 17:55, 3 March 2018 (UTC)
Magnetic imaging section
Does not use MEDRS sources and is dubious. Article concerns should go beyond the lead. [2] This is a very short article—it should at least use secondary reviews. SandyGeorgia (Talk) 10:58, 3 March 2018 (UTC)
- Is this of any use? Little pob (talk) 16:32, 3 March 2018 (UTC)
- Thank you, but that source does not meet MEDRS. It is an advocacy organization. In the US, there are efforts to get MRI-guided biopsy covered by medicare and insurance, so we have to take care with advocacy. I am unaware of a good MEDRS source for this text, but anecdotally, no physician we have spoken to at a top-rated NCCN research and teaching hospital has indicated support for this claim. A secondary review should be located. I am told—-again, this is anecdote—-that MRI guidance is sometimes better, sometimes not. SandyGeorgia (Talk) 16:49, 3 March 2018 (UTC)
- Here is an example of what is going on in the US. http://drgeo.com/how-to-get-your-prostate-mri-covered-by-your-health-insurance/
And here is a primary source example of research underway. Although it cannot be used in the article, it gives helpful explanations of the state of the art. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5503963/
I do not fully understand what is going on in the UK, but I imagine their demographics and economics are different than the US. In the US, something like 10,000 baby boomers per day are turning 65, enrolling in medicare, about half of those are men, 1 in 6 will have prostate cancer, 12% of those will die of prostate cancer, and 66 is the average age of detection. All this means that the US has a ticking time bomb of pending cancer death among baby boomers, whose detection and treatment will be paid by taxpayers, thanks to the USPSTF expansion of power under Obamacare.
If Wikipedia had an article on a condition affecting women in a similar state, the gender police would be all over it. SandyGeorgia (Talk) 18:59, 3 March 2018 (UTC)
Painful biopsies?
While there is some much needed critical discussion of PSA screening compared to the main article on prostate cancer (which essentially says that screening is bunk), this article also repeats the canard that biopsies are high-risk, painful, etc. This is not true. I've had 3 biopsies, with 58, 17, 1nd 21 samples taken. The first had 46 perineal and 12 via the rectum, the second only perineal, and the third only rectal. All cases were one night in hospital. After the fist one, I went to a concert on the day I was released. The rectal one was the easiest: I had slight discomfort, not even pain, for about an hour after waking up from the anesthesia. Many, many, many, perhaps even most, patients who dies of prostate cancer die because they have heard false information about how dangerous a biopsy is and hence wait too long. — Preceding unsigned comment added by 193.29.81.232 (talk • contribs) 11:01, 8 January 2018 (UTC)
- Thankfully, that seems to have been removed. And your point is spot on. Imagine if we went all hysterical over what women endure every year with a gyn exam. I was there, in the room. There was absolutely nothing painful about my husband's biopsy, and while it was intrusive, I found it much less intrusive than an annual pap smear. At least he got to be on his side, while women get to spread eagle. And while biopsy may provoke anxiety ... well, cancer does that, and you are not having a biopsy unless cancer is suspected.

Baseline at an early age
Removing this text about recommendations for baseline testing was warranted because it was poorly sourced and in the wrong place. But although I provided a source for this or similar text yesterday (in the section just above this one), there is now no mention of baseline testing recommendations starting at age 45, in spite of PMID 27995937 above. A thorough read of all of the sources would probably make for less piecemeal editing; it can be difficult for those not immersed in or experiencing a condition to be aware of what they are unnecessarily removing. When you are not yet sure if a sentence can be sourced, then tagging it with cn is more useful than removing the text. If a man has no baseline screening, then PSA results becomes difficult to interpret, and you lose time towards cancer detection or end up with unnecessary treatment. This is covered in the source I provided above, so this text should have been adjusted, not removed. Please, friends, take greater care to understand all sources when editing this topic that affects so many men.
Jytdog, have you seen my question above about my edit summary? I would still like to understand why you object. SandyGeorgia (Talk) 18:16, 5 March 2018 (UTC)
- Quackguru, thanks for taking the time to clean this up and expand it, but this is pretty close paraphrasing. I am not good at correcting too close paraphrasing, so perhaps you or someone else will recast this sentence:
- Source [4]
- Other guidelines recommend starting at age 45, due to growing evidence that an elevated baseline PSA can be predictive of future lethal disease.
- Wikipedia [5]
- Other guidelines and centers specializing in treating prostate cancer recommend obtaining a baseline PSA in all men at age 45, due to emerging evidence that an increased baseline PSA can be used to detect future deadly disease.
- We can't maintain the same sentence structure, and just change three words (growing --> emerging; elevated --> increased; lethal --> deadly).

COI sources
The following discussion is closed. Please do not modify it. Subsequent comments should be made on the appropriate discussion page. No further edits should be made to this discussion.
Per this, I'm wondering are editors considering conflict of interest, when considering sources? Of course a COI does not disprove a source, but it does warrant caution. I'm not prepared to edit this article or comment on what is the most reliable sources as it is outside my knowledge area. I'm just a little concerned about whether harmful biased information, with the best of intentions, could be, or is being, added to this article with the potential to cause a lot of harm to guys like me. I'm academically ignorant of this subject matter and have a concern (which may be unfounded) that I am querying. Thanks.--Literaturegeek | T@1k? 02:08, 6 March 2018 (UTC)
- Here is how to correctly use that source. First, it explains quite well what is going on with prostate cancer screening. Second, there are scores of sources that explain the same. Read Catalona, ignore that his COI may be a factor, use his article to understand the problem, then use the many other sources that explain same to fix the article. Example: can you dispute Catalona that there are no urologists or oncologists on this board? Can you dispute that the role of this task force changed under Obamacare? You cannot dispute that there are sources that backup the actual problems with the data, as Catalona explains, because that same info can be found in a number of sources. Summary: read, digest, understand what Catalona is saying, because he puts it all in one place. But also read everything else. We have a few proponents of one POV wanting to exclude all other from these articles. Use Catalona to understand what is being excluded, then use other sources that may not explain the issue as well as Catalona does to source text. And, there are some issues that can be sourced to Catalona even with COI (e.g. the makeup of the task force body, etc.)
The problem here is that we have some rational beings who apparently won't even read Catalona to understand exactly what the best prostate cancer people in the world, in the best prostate cancer treating facilities in the world, all know. Because none of the top treating prostate cancer groups in the US hold the same POV that Wikipedia is espousing and endorsing, Wikipedia can choose to ignore reliable sources and be on the wrong side of prostate cancer deaths, or Wikipedia can choose to write an article that correctly reflects all POVs, and hold itself as a neutral observer of the controversy, rather than a contributor to it. THAT is the role that good editors should be playing, rather than vociferously arguing for ignoring some sources to maintain a POV article. Catalona says nothing that cannot be found in other sources-- he just happens to wrap it up nicely in one article.
Further, we all only need to look up on this talk page, to this discussion, to see that discussion of sources works better than editing articles too fast, without knowing all that is out there in ALL sources. I have been accused of bringing my personal situation to these discussions. Well, yes. Because I am living with the USPSTF mistake, and I have read secondary reviews quite extensively, and I knew portions of that text were accurate, even if not yet correctly sourced. Yes, I bring the personal ... I am immersed in these sources as a matter of fact now. People, stop insisting on one POV over another, and start listening to each other. There are many many sources ... prostate cancer is a leading medical issue for men, and a cash cow, hence a complex topic. You cannot broad brush it, fix only the lead, or fix the article based on a cursory understanding of prostate cancer. SandyGeorgia (Talk) 17:20, 6 March 2018 (UTC)
- Oops, another point for LitereatureGeek before I hit the road. Reading Catalona will help you understand that there are broadly three different approaches to detecting and treating prostate cancer. One, for those on Medicare. Two, for those who have insurance other than or beyond Medicare. Three, for those who can afford to pay for their own care. As of now, for a cancer that affects a huge number of men, we have no one gold standard for detection or treatment, and we have patients who do not have access to some proven methods; we can hope these issues will get settled somewhere down the road. For now, they are not.
Meanwhile, reputable treating physicians still know what works (hint: not USPSTF recommendations).
To understand just how complex this mess is, look at the situation in the UK. NHS won't endorse (inexpensive) screening across the board, but now there will be same-day (expensive) screening in the UK using MRI, which is not paid by most insurance in the US. Same day, what the heck? MRI, holy cow! No such thing in the US (we couldn't have an MRI because our insurance won't pay it), yet the UK jumps straight to it, while discouraging less costly screening. NHS employs a methodology that is not yet proven, and available in the US to those who can pay for their own care. (Our Dr. recommended against, even if we paid for it ourselves. His logic was that it was an unproven methodology, that we would be paying out of pocket, and that he had no confidence that it would do a better job of detecting the cancer which he could already feel on very inexpensive Digital Rectal Exam.) Catalonia's article, regardless COI, lends understanding to the economic problem that is driving down screening, resulting in more advanced cases of cancer being detected. SandyGeorgia (Talk) 18:32, 6 March 2018 (UTC)
- That (MRI & same-day biopsy) is just an experiment in I think 3 hospitals, Sandy. The NHS doesn't do mass screening, and given the new results of a massive trial announced this week (see below) isn't even moving in that direction, but will do tests for individuals who request it or whose symptoms lead their GP to suggest it, after their GP has set out the pros and cons. Johnbod (talk) 03:09, 8 March 2018 (UTC)
- Thanks, Johnbod-- I had asked you above what on earth they were thinking (expensive MRI and same day, yes, but inexpensive PSA, no), but you may have missed that post. I am still trying to imagine what they will do if their experiment gives good results-- offer MRI to everyone as the standard? If detection of prostate cancer by MRI becomes the standard, it will really be expensive, and I wonder what that will do to Medicare's costs in the USA. SandyGeorgia (Talk) 17:01, 8 March 2018 (UTC)
- User:SandyGeorgia, I don't really know - I usually look first to my old workmates who do the CRUK science blog for sensible information and analysis on cancer news, but so far they have been silent on this. The best info I can find now is the NHS press release, which of course all the papers parrot], and which doesn't fully answer the questions. It is just 3 hospitals (all very local to me).

- I typed up a reply and lost it when browser refreshed for no rational reason, ugh. Here goes again. Your suggestion, Sandy, to use the Catalona review to give a general overview of the controversy seems sensible and I see no reason why it can't be cautiously cited in the article alongside POVs that may differ from Catalona. I think the issue here is WEIGHTing the sources. It is very unfortunate you are affected by this in your real life and I hope your husband gets the best medical treatment possible and recovers soon.--Literaturegeek | T@1k? 13:15, 7 March 2018 (UTC)
- Thanks for the well wishes for recovery, Literaturegeek ... we do have the best care possible as we fortunately live within driving distance of a top-rated NCCN teaching hospital and facility. My first tipoff to the problems in these articles was that NCCN guidelines were not even mentioned a few weeks ago, and they reflected almost none of my reading in secondary reviews, books, or in literature given to us at the hospital.
Cure is achievable until cancer escapes the prostate. There is no cure once cancer escapes the prostate. After that, the word "recover" doesn't really apply ... it becomes a matter of calculating your life expectancy and then choosing from an array of treatment options that you hope will allow you a decent quality of life for your remaining years. That is, "pick your poison" from various intended or side effects (urinary incontinence, fecal incontinence, erectile dysfunction, mood swings, depression from male castration, and so on) and hope that whichever option you pick for treatment does not leave you with side effects that will make your remaining years not worth living.
So, there is still so much missing in our articles. In bringing this suite of articles up to snuff, we have to remember that the whole story is not told by life expectancy statistics; it is about how miserable or not your remaining years will be when the cancer is detected too late. It is a challenging topic and it could be fun to bring the articles up to snuff if everyone would set aside ego, entrenchment, and use the talk page as in the example I gave above. We cannot fix this suite of articles quickly. Best, SandyGeorgia (Talk) 14:06, 7 March 2018 (UTC)

The new results of a very large (over 400,000 participants) study in the UK are getting a lot of publicity here, and the wind is blowing against mass screening. Note the study covered one-off tests only (then follow-up depending on the initial results). I wonder if our articles are as careful as they should be in saying what the type/frequency of screening studied was? The easiest way in is this Cancer Research UK science blog entry, and here's the JAMA paper. That CRUK graphic could be used in the article, btw. Johnbod (talk) 16:51, 7 March 2018 (UTC)
- RE "our articles are as careful as they should be in saying what the type/frequency of screening studied was", our articles are not carefully explaining, yet, anything about how screening is applied, or misapplied. They are no longer dangerously representing only one outdated POV, but they aren't yet anywhere near complete. As long as they are no longer dangerous, I think that's the best we can hope for with Wikipedia.
It will be interesting to see how this UK primary study pans out under secondary review ... for example, I cannot imagine how one-off testing could work. If we had had only one-off testing, and only follow-up based on initial results, my husband would today have undetected moderately aggressive prostate cancer, because he had four normal PSAs before the spike. We are glad he had more than one PSA :)
Moving towards "one-off" or no testing means prostate cancer will not be detected until the tumor is palpable on Digital Rectal Exam, which is not good ...unless the NHS thinks they can replace inexpensive PSA screening with expensive MRIs for everyone ... maybe the economics of healthcare in the UK are different than in the US.

- I think we should discuss how to mention this study in this article. This is an enormous, high-quality study, and it is exactly the kind of thing that MEDRS's statements about "large randomized clinical trials with surprising results" is intended to cover. While we wait for proper reviews, the results from this massive study is worth mentioning. My initial thought is that the mention should closely follow the MEDRS example, copied here for the convenience of people who don't have it memorized:
"A large, NIH-funded study published in 2010 found that selenium and Vitamin E supplements, separately as well as together, did not decrease the risk of getting prostate cancer and that vitamin E may increase the risk; they were previously thought to prevent prostate cancer." (citing PMID 20924966)
- (SandyGeorgia will probably remember that Eubulides had written a far shorter and simpler example back in the day, but this is the current one.) In this case, it would probably look something like this:
"The largest-ever study of PSA tests, published in 2018, found that offering a single PSA test to men in their 50s and 60s somewhat increased the likelihood of being diagnosed with low-risk prostate cancer, but did not change their risk of dying from prostate cancer during the next ten years." (citing the JAMA paper)
- We could, if wanted, specify that "very large" means more than 400,000 men. I do think that it's important to clearly state that the test looked at the long-term effect of offering only a single PSA test to men in the target age range, rather than annual screening. We could also point out that the risk of dying in this group was already low (ACS gives the 10-year survival as 98% overall).
- This is the largest-ever study on the subject, and the result doubtless surprised and dismayed people who favor PSA testing (or who favor screening and assume that PSA testing is the only/best way to screen). The study itself may actually be WP:Notable. Is there any good reason not to mention its existence? WhatamIdoing (talk) 02:33, 10 March 2018 (UTC)
- "enormous, high-quality study," is your judgement, as is what to emphasize out of it. That is what we use secondary sources to tell us. There is no hurry. Jytdog (talk) 05:47, 10 March 2018 (UTC)
- Interesting study. With how controversial this topic is probably best to stick with reviews and position statements. Doc James (talk · contribs · email) 05:44, 13 March 2018 (UTC)

In-article confusion
In this version, after this edit (with two corrections) we end up with confusion:
- A 2018 review recommended against primary care screening for prostate cancer with DRE due to the lack of evidence of the effectiveness of the practice.[23] If a digital exam suggests anomalies, a PSA screening is then performed. If an elevated PSA level is found, a digital exam is then performed.[2]
Viewing the second sentence, relative to the first, could we think about where this contradiction leaves readers? Doc, if you do not have time to correctly work in a recent review, you could consider adding it to talk for someone else to work in. Wikipedia's article is going in circles.

Source
It has been suggested to use this page from cancer.gov as a source. Jytdog (talk) 06:47, 10 March 2018 (UTC)
- No, actually, it hasn't. It has been suggested to use that lay-oriented page as a model, which is not the same thing as a source. To oversimplify, the proposal is much closer "use this as an inspirational page for writing style" than to "cite this webpage". WhatamIdoing (talk) 15:37, 10 March 2018 (UTC)
- It is also a decent source and I am happy to see it used. Doc James (talk · contribs · email) 05:45, 13 March 2018 (UTC)
- WAID is correct-- I was suggesting this source for the way it is written, as an example of how it is possible to neutrally and dispassionately explain the controversy, in a way that is helpful to readers. Think in terms of "gray" rather than "black-and-white" thinking. SandyGeorgia (Talk) 14:02, 16 March 2018 (UTC)
Model
My apologies if this has already been offered, but this page looks like the way we need to write this article for it to be comprehensive, updated, accurate and neutral (relative to US) ... it covers the controversy, explains what part of PSA screening is controversial and why, discusses current use, and discusses the rest of the stuff that the Wikipedia article is completely missing (like how to use PSA during watchful waiting and after prostatectomy, for instance).
Instead of using this sensible, reader-oriented page from cancer.gov, we are/(were) using a highly abbreviated health professional version which isn't very helpful. In fact, even using that abbreviated page when we have this comprehensive page from the same source smells like cherry picking. https://www.cancer.gov/types/prostate/psa-fact-sheet
This model shows that writing this article with all caveats and all POVs should not be that hard. Notice that it distinguishes between over diagnosis and over treatment (something people mix up on this talk discussion). If we could all read this article and decide if there is anything in it we strenuously object to AS A MODEL, perhaps then we could dispense with a gazillion RFCs, arguing sentence by sentence while the articles are overall horrid, and have a direction in which to work. TOGETHER. For men's lives' sake. Then we have to make sure to add in non-US (there are loads of secondary reviews about how PSA screening is used in other countries). SandyGeorgia (Talk) 19:18, 8 March 2018 (UTC)
- I think there are some advantages to that model. However, there are a few things we'd have to leave out, especially on using the PSA test to follow survivors. Here's the structure that I see on that page:
- What is the PSA?
- Efficacy (does it work/is it recommended) for screening
- Results/how to interpret
- What happens if you get "bad" results
- Limitations and harms
- Research
- The main difficulty I think we would have is that cancer screening ≠ PSA-based cancer screening, and that page is pretty focused on PSA testing. WhatamIdoing (talk) 02:43, 10 March 2018 (UTC)
- yes, prostate screening is broader than PSA. But yes PSA was the only lab test used for a long time. Digital examination has been done for a long time. Jytdog (talk) 17:21, 10 March 2018 (UTC)
- Expanding that small section would probably be a straightforward and non-controversial way to improve this article. It doesn't even link to the main article for that procedure. (I'll go fix that much now.) WhatamIdoing (talk) 03:36, 11 March 2018 (UTC)
- yes, there are pieces of that article that could be used throughout the suite-- I pointed it out for the neutral writing tone, rather than factoids per se. But, there are a number of sub-articles in the prostate cancer suite that need to be updated, and parts of that would be used in each. We have (at least, and more or less bottom to top in terms of summary style):
- Digital exam is not "done"; while science and Wikipedia debate, prostate cancer continues to happen in the real world, and general physicians and urologists continue to use DRE to detect it. Perhaps something better will come along in our lifetimes. SandyGeorgia (Talk) 14:14, 16 March 2018 (UTC)
- I'm not sure if Jytdog is saying that DRE is 'done' as a technique as in no longer considered useful. I think they may have been saying that DRE is a test with a long history, along with the lab test for PSA. Nil Einne (talk) 07:12, 18 March 2018 (UTC)
- yes, prostate screening is broader than PSA. But yes PSA was the only lab test used for a long time. Digital examination has been done for a long time. Jytdog (talk) 17:21, 10 March 2018 (UTC)

ProstaGene- recent edit moved to talk page
Hi, I am moving a recent edit here so that we can discuss it on the talk page first. I am not familiar enough with the literature in the field to know if this screening tool is supported by evidence, but both references were from 2013 (the second reference is definitely a primary source) and I thought it would be a good idea to share here and see if there are strong more recent sources. Here is the deleted text (and references):
- ProstaGene identifies men with clinically significant prostate cancer who would benefit from further testing and treatment. ProstaGene was developed using an hypothesis agnostic bioinformatics approach, defining a gene signature that predicts biochemical recurrence or distant metastasis with a high hazards ratio (9.2, 11.6) and AUC (0.69, 0.8) [1] [2]
