Prostate cancer screening using the prostate-specific antigen (PSA) test for asymptomatic men is controversial: experts are divided, and Australians should not routinely well-informed.
Prostate cancer is a slow-growing cancer. Men usually tend to die with it – and never know that they had it – than to die from it.
Although there may be some evidence that PSA testing improves prostate cancer survival, it's also Evidence of over-diagnosis. This is where men are diagnosed and treated for cancers that might never harm them.
our Recently published research shows that after access to high-quality, evidence-based details about risks and advantages, men's desire for a PSA test decreases.
Why the confusion?
Many countries Do not recommend Prostate cancer screening Men without symptoms. Although there isn't a national screening program, Australian health practitioners perform opportunistic screening for asymptomatic men.
Because PSA is a straightforward blood test, it is usually added to an individual's blood work done for other reasons, reminiscent of cholesterol or fasting blood glucose. By adding a PSA request to the pathology form (sometimes without their knowledge), asymptomatic men are being screened for cancer: whether or not they wish to be or not.
Late last 12 months, Australia's National Health and Medical Research Council (NHMRC) Information for health practitioners Most of the report Instructions (including NHMRC) Make a recommendation Men must be informed of each the potential advantages and harms related to prostate cancer screening, nevertheless it is. Far from normal.
Asking men
To learn more about whether information in regards to the harms and advantages of PSA screening made a difference in men's health decisions, We used Known as a novel method A citizen – or community – jury.
We randomly assigned 27 male volunteers aged 50 to 70 years to either a two-day “community jury” group or a control group. The control group was given PSA fact sheets which can be found. Cancer Council Australia And Andrology Australia Websites

The Community Jury Group also received these fact sheets and two days of expert input, questions and deliberations. On Saturday, three experts gave “evidence”:
-
Professor Jim DickinsonA professor of family medicine on the University of Calgary provides information on basic prostate biology and cancer
-
Professor Paul GlasioA general practitioner and expert in evidence-based medicine (and co-author of this text) gave the “evidence” about prostate cancer screening, emphasizing the potential harms.
-
Professor Frank GardnerA urologist and prostate cancer specialist on the University of Queensland gave “evidence” emphasizing the potential advantages.
(You can watch videos of the presentations. Here And Here).
The men locally jury group were then capable of ask questions on the data from the experts.
On Sunday, the lads of the Community Jury discussed the data with a facilitator, posed any further inquiries to the experts, after which considered two “community questions” as a bunch with out a facilitator:
-
Should government campaigns on PSA screening be provided and, if that's the case, what information must be included in these campaigns?
-
What do you concentrate on a government-sponsored invitation program for prostate cancer tests as a bunch of men?
We also asked men in the event that they would personally be screened for prostate cancer with a PSA test.
Information is essential.
Most of the lads were shocked by this information. The men of the community jury unanimously voted against a government campaign targeting the general public about PSA screening and against a scientific invitation program. The men agreed that:
We don't want the federal government to ask us or our colleagues to come back along and get tested. We don't want that to occur because we don't want our colleagues to be upset. We don't want people rioting, we don't want our government to waste our money.
Instead, and without prompting, the lads really useful a campaign targeting general practitioners to assist them provide consistent information to their patients in regards to the harms and advantages of PSA screening.

We asked all men before and after the study whether or not they intended to be screened for prostate cancer with a PSA test in the long run.
Before the study, men in each groups had similar intentions: most intended to get tested;
After the study, more men locally jury had modified their minds (intended to get tested less) about being screened for prostate cancer. When asked three months later, it remained the identical. As one participant said:
When I got here in I used to be of the opinion that each man over 60 must be screened, but now I feel I've modified my mind, that it's a private decision.
Not all men locally jury group modified their individual decision to be tested, but not all men wanted an information campaign or an invite program for screening. Men were clearly able to differentiate between public health preference and individual health judgment.
Community juries and health policies
Health screening tests are on the rise. Depending in your age, you could be tested for a lot of “conditions” for which you could have no symptoms, reminiscent of osteoporosis or vitamin D deficiency. But while all carry an overdiagnosis risk, few screening tests Offers proven benefits.
To develop appropriate screening policies, and to find out where to direct health funds in a cash-strapped fiscal environment, we want to listen to from the people affected by these policies. Community juries offer governments a platform to hearken to the voices of people who find themselves well-informed by experts and consider the data in accordance with each individual values and social advantages.
The community has a jury. Already used It is a promising tool to tell government policy in South Australia and to assist shape health policy in local, state and national jurisdictions.
