Andrology Australia is well established as Australia’s peak body in promotion and education of male reproductive health. The APCC is the National research and education body in prostate cancer. The two organisations working closely together cements their position as a national force in prostate cancer research and education in Australia. “Consultation with a wider network of individuals and organisations working in prostate cancer will lead to better decisions being made about priorities and strategies in this area.” The combined strength of clinical and scientific expertise will ensure that quality research and evidencebased education is made available to the wider Australian community. Professor Rob McLachlan, Director of Andrology Australia, said this collaboration will have great benefits for the community. “The APCC leads the way in education and research into prostate cancer and Andrology Australia has excellent outreach and information networks,” Prof. McLachlan said. Andrology Australia will manage the secretariat for the APCC for two years to enhance collaboration and minimise duplication of effort in prostate cancer research and education. Professor Villis Marshall, Chair of the APCC, said this collaboration may also lead to increased financial support to further prostate cancer research and education in Australia. “Improved understanding of prostate cancer in the community is fundamental to increasing the level of financial and in-kind support,” Prof. Marshall said. To find out more about becoming a member of the APCC, contact Andrology Australia on 1300 303 878 or email info@andrologyaustralia.org From the Director Prostate cancer is the most common cancer in Australian men, aside from some forms of skin cancer. The disease is diagnosed in about 12,000 men in Australia every year. As prostate cancer often has no symptoms, it is important to educate men about the disease and who is at risk, so they can make informed decisions about whether or not to get tested for prostate cancer. There is much debate about the role of the PSA test in diagnosing prostate cancer, as it doesn’t tell you definitely that you have cancer. It tells you that there is something awry with the prostate. Further tests are needed to confirm a diagnosis of cancer. Being tested for prostate cancer can save a man’s life, but a false positive test result from a PSA test can lead to unnecessary further testing and medical treatments often with unpleasant side-effects. This issue of the Healthy Male focuses on the PSA test. If you are a man over the age of 50, or have a family history of prostate cancer, talk to your doctor about the benefits and risks associated with testing. Professor Rob McLachlan Community education Men Behaving Positively A series of annual ‘Men Behaving Positively’ public health forums, spearheaded by Peninsula Health and Rotary with support from Andrology Australia, have succeeded in educating men about social, mental and physical health issues over several years. The next forum, ‘Men, work and family relationships - navigating the road map and staying sane’ will be held at the Frankston Arts Centre Auditorium on Wednesday June 13th 2007, from 7.30pm to 9.30pm. This forum aims to raise awareness about the link between general and reproductive health, and that making lifestyle changes to improve physical and mental health can also benefit quality of life and relationships. Guest speakers include: • Merv Hughes – Ambassador for Andrology Australia • Les Twentyman – Youth worker, Open Family Foundation, Victorian of the Year 2006 • Wayne Schwass – Champion AFL footballer, CEO Sunrise Foundation • Tom Bentley – former Director DEMOS (UK), Director Policy and Cabinet Victoria • A/Prof. Neil Cole – award winning playwright, mental health consumer and advocate For further details about the forum contact Greg Holding at Peninsula Health on 0419 007 638 or Gholding@phcn.vic.gov.au Coming events Andrology Australia advisory forum Have a say in our future direction! Plenary speakers include: Andrology Australia is holding an advisory forum on men’s health in Adelaide, 26 – 27 May 2007, and we want you to be involved. • International speaker Prof. John McKinlay, Chief Investigator, Massachusetts Male Ageing Study, USA Over the past seven years, Andrology Australia has built a strong foundation for educating the community and health professionals on men’s health. Prostate disease (including prostate cancer), testicular cancer, male infertility, androgen deficiency and erectile dysfunction affect large numbers of Australian males, and in all of these conditions, there are many aspects that are still poorly understood. • Dr Mark Wenitong, President, Australian Indigenous Doctors’ Association The Andrology Australia advisory forum aims to provide an opportunity to all interested health professional and community members to discuss and contribute to the future direction of Andrology Australia. The forum will showcase a number of community, professional and research projects, and general and specialist workshops will increase attendees’ knowledge on all aspects of male reproductive health. It is hoped the forum will also provide an opportunity for research and education collaborations to evolve. • A/Prof. Michael Baigent, Clinical Advisor, Beyond Blue • Governor Prof. David de Kretser AC, Former Director Andrology Australia Plus a special guest appearance by Merv Hughes, Ambassador for Andrology Australia.

For more details, please visit www.asnevents.net.au/apcc Focus on: PSA test What is a PSA test? A PSA test measures the level of Prostate Specific Antigen (PSA) in the blood. It is a blood test that can help diagnose prostate disease. Prostate Specific Antigen is a protein made mainly in the prostate gland and low levels of PSA are normally present in the blood stream. As a man ages, the prostate grows and the level of PSA also increases. PSA levels for different age groups of Western men Age (years) Serum PSA (ng/ml) – average Serum PSA (ng/ml) – upper limit of normal 40-49 0.65 2.0 50-59 0.85 3.0 60-69 1.39 4.0 70-79 1.64 5.5 A high PSA in the blood almost always means that something is wrong with the prostate, but not necessarily prostate cancer. The causes of a high PSA include the benign (non-cancerous) growth that accompanies ageing (benign prostatic hyperplasia, BPH), inflammation or infection of the prostate (prostatitis), and, least commonly, prostate cancer. Is a PSA test worthwhile if there are no symptoms of prostate cancer? Although there are still many questions about the value of using PSA to test for prostate cancer because there are too many false positive and negative results, it is the best test that is available. A false positive result occurs when PSA levels are high but there is no prostate cancer. A false negative result occurs when PSA levels are low or within the normal range, but prostate cancer is present. In the early stages, prostate cancers usually do not show any symptoms. Cancer can grow in the prostate and not affect urine flow until it is late stage prostate cancer. A PSA test will give an indication of problems in the prostate before symptoms have developed. How well does the PSA test work for finding prostate cancer? About one in three men with a PSA between 4 and 10 ng/ml could have prostate cancer, although this proportion varies with the population tested. Of 100 unscreened men in each age group tested for the first time1-4: Age Men who will have a PSA over 4.0 Of these, men who could have cancer 50s 5 out of 100 1-2 men 60s 15 out of 100 3-5 men 70s 27 out of 100 9 men Recent studies have shown that there is still a small risk of prostate cancer, even if blood PSA levels are normal for age. Therefore even a normal blood PSA level does not mean that there is definitely no prostate cancer present. The only definite way to confirm whether prostate cancer is present or not is by prostate biopsies (taking small samples of tissue). Transrectal ultrasound (TRUS) biopsies are almost always performed using an ultrasound probe which is placed in the back passage (rectum) to visualise the prostate. A small needle is then inserted into the prostate gland through the rectal wall to remove samples from different parts of the prostate gland. Biopsies are not a minor medical procedure and can be accompanied by short term side-effects such as blood in the urine, faeces and/or ejaculate. After biopsies, patients may have temporary difficulty passing urine. Importantly, there is a low (less than 1%) risk of serious infection as a result of this procedure but it is rarely life-threatening. How do I make a decision about whether or not to have a PSA test? Having a PSA test may require further decisions after the test results are back, especially if the blood PSA level is raised. There are several things to consider before having a PSA test for prostate cancer: • Your level of concern about having prostate cancer • Your risk of having prostate cancer e.g. is there a family history of the disease • The risk and benefits of early detection. The benefit being that a PSA test may detect prostate cancer when it is small and curable. The risks being those associated with unnecessary and possibly harmful treatment from surgery or radiotherapy (with or without male hormone suppression) with complications such as erectile problems (difficulty having erections, impotence) and urinary incontinence (inability to hold urine, urine leakage, having to wear urine pads). Unlike many other cancers, the majority of prostate cancers tend to progress slowly with most men dying from other diseases such as a cardiovascular episode (heart attack, stroke) rather than prostate cancer. Therefore a man’s age and his personal choices must be considered before deciding to have a blood PSA test and/ or deciding what to do if raised PSA levels are found. For example, an increased PSA level due to a prostate cancer in an older man aged 75-80 may not be a major health threat when other factors are considered such as life expectancy and general health. On the other hand, in an otherwise healthy younger man aged 50-55, an increased PSA level is more likely to affect his life (due to the effect of prostate cancer or the complications of treatment) and further investigation should be considered. The risk of death from prostate cancer depends on the man’s life expectancy and the aggressiveness of the cancer. As a rule, men with high blood PSA levels with a life expectancy of 10 years or more (or a family history of prostate cancer) should consider further testing to make the diagnosis of prostate cancer. With more aggressive cancers, local treatments do not always cure cancers as microscopic spread may have happened that cannot be detected with scans and X-ray imaging. These patients need to be followed so that other treatments can be undertaken as indicated. Will a PSA test tell me if I have prostate cancer? A single PSA test is not a reliable indication of prostate cancer, unless it is extremely high. Men with a blood PSA level over 10 ng/ml have a 50 per cent risk of having prostate cancer. An increased PSA level may cause concern and anxiety in some men. It is important to remember that not everyone with increased levels of PSA has prostate cancer. Other prostatic conditions, such as BPH or prostatitis can also cause increased PSA levels. Results of a PSA test need to be interpreted with caution. Prostatic biopsies are needed to confirm prostate cancer is present and to give an idea of how aggressive the prostate cancer is. New research suggests that the rate or how quickly PSA levels rise over time is important (this is called PSA velocity). Regular tests, every one to two years, are necessary to check if the level of PSA changes with time. If the PSA level doubles in 12 months, this is of concern as it may be due to the presence of a fast growing cancer or infection in the prostate (prostatitis). So, if PSA level is increasing, further action should be taken and a specialist Urologist consulted for more detailed monitoring. What if I choose to get tested? If a man makes an informed decision to be tested for prostate cancer, it is important that a digital rectal examination (DRE) is also performed. A combination of a PSA test and DRE is better than either one alone. If a PSA test is performed, it is important to return to your GP for follow-up testing every 12 months. And if a PSA level is high for your age, the test should be repeated. For men with PSA values less than 1ng/ml with no risk factors, further testing may not be needed for several years. What other tests can check for prostate cancer? There are currently no tests better than PSA for testing for prostate cancer. Throughout the world, investigators are trying to develop more accurate and reliable tests for prostate cancer. There are some refinements of the PSA test that some doctors believe may add more value to the test. For example, the free to total PSA ratio is another blood test that can help determine whether or not an elevated PSA level may be a result of prostate cancer. A proportion of the PSA circulating in the blood is free. Non-free PSA is bound to proteins. Men with prostate cancer will usually have lower levels of free PSA as a proportion of their total PSA measurement, than men with prostate enlargement (BPH). This ratio (or percentage) is most useful for PSA values between 4 and 10 ng/ml. What are the benefits and risks of testing for prostate cancer? This information can help the patient and doctor make a decision regarding the options for further investigation and management. An important benefit of testing for prostate cancer is that early detection of prostate cancer when it is smaller and curable gives better chance for more effective treatment and cure. The decision to be tested for prostate cancer is entirely a personal one in consultation with your doctor to help you make the best informed choice for your situation. This information is provided to help men and their families understand the PSA test, and to make discussion with a doctor easier. Andrology Australia recommends readers speak to a local doctor about PSA testing and any other health concerns. Risks of testing for prostate cancer include: • If the PSA level is raised, it does not always indicate prostate cancer. Biopsies will be needed to determine if cancer is present. • Prostate biopsies and treatments for prostate cancer have sideeffects that may affect the quality of life. • If prostate cancer is slow-growing, a decision may be made not to undergo any active treatment (watchful waiting/active surveillance with further biopsies at a later date) but to have careful monitoring. In some men this approach can cause considerable anxiety.

As part of this online program, a decision-aid is available to underpin the informed choice discussion which is currently available to download from the Andrology Australia website. As community awareness about prostate cancer is increasing, GPs may find more patients wanting to discuss prostate cancer and the possibility of being tested. A number of education activities on prostate cancer and PSA testing are available through Andrology Australia for GPs and other health professionals, to assist in decisionmaking and discussion with patients. An audio interview on PSA testing is available to download from the Health Professional section of the Andrology Australia website (www.andrologyaustralia.org). Consultant urologist A/Prof. Mark Frydenberg discusses PSA testing and the latest developments in the use of the test for the diagnosis of prostate cancer. This interview was recorded for Edition 3 of the RACGP General Practice Essentials CD. An online Active Learning Module (RACGP/ACRRM accredited) on prostate cancer testing is currently being developed with support from Andrology Australia and will be available mid 2007. The module is being developed by the Queensland Cancer Fund through the ThinkGP online training facility in collaboration with the Australian Prostate Cancer Collaboration education group, with input from the Queensland Faculty of the RACGP and the Northern Section of the Urological Society of Australasia. Research round-up Sexual functioning after treatment for localised prostate cancer Men who have had prostate cancer treatment often experience longterm sexual dysfunction, which can be very distressing and affect quality of life. The term sexual dysfunction covers not only erectile dysfunction but also orgasmic function, sexual desire, and ejaculatory function. A study is being conducted to better understand the types of issues associated with the sexual dysfunction that men experience, in particular those men going through radical prostatectomy or permanent brachytherapy. The chief investigator Dr Sue Burney and lead researcher Dr Fiona Newton said that to date, the study has found some differences in sexual function between men who underwent radical prostatectomy and permanent brachytherapy. For example, preliminary results suggest that men who underwent prostatectomy had significantly lower levels of erectile and orgasmic function nine months after treatment compared with brachytherapy patients. However, Dr Newton stated that “sexual desire after treatment was similar between the two groups.” Qualitative data obtained from patient telephone interviews suggested that some men with sexual dysfunction also experienced changes in their wellbeing. For instance, some men reported changes in how they perceived themselves as men while others noted changes in their emotional affect (mood). Dr Newton stated that “emotions such as bereavement and disappointment were not uncommon”. However, the research team (including A/Prof. Mark Frydenberg and A/Prof. Jeremy Millar) stress that not all patients experienced negative changes in these areas. Interpersonal relationships played an essential role in the way in which prostate cancer patients coped with sexual dysfunction. “Many patients emphasised the importance of being able to talk with partners, friends, fellow prostate cancer patients, and medical personnel who understand the issues,” said Dr Newton. “The preliminary results would tend to suggest that communication and compassion may well be important in helping men adjust after prostate cancer treatment.” The findings from this study emphasise the importance of managing expectations of prostate cancer patients and their partners, and providing psychological support during the post-treatment recovery phase. Andrology Australia supported this study conducted by the School of Psychology, Psychiatry, and Psychological Medicine, Monash University.

Selenium is an essential mineral in the human body that acts as an antioxidant. Antioxidants can help prevent damage to cells with the potential that they may reduce cancer risk. Plant foods are a major dietary source of selenium, but it is also found in meats and seafood. Most often selenium can be found naturally in foods such as Brazil nuts, fish, red meat, beef and chicken liver, grains and eggs. A recent study has found that a diet high in selenium may reduce the risk of prostate cancer in selected men1, but this only applied to men who also had a high intake of vitamin E or men who were taking multivitamins. The study used data from the Prostate, Lung, Colorectal, and Ovarian Cancer (PLCO) Trial conducted in the USA, and looked at 724 men with prostate cancer and a control group of 879 men without prostate cancer. Men in this study had blood samples taken over a number of years with the aim of identifying factors present in men who went on to develop a variety of cancers. As this was a longterm study, blood samples from the men who went on to develop prostate cancer were available from time points before the diagnosis was made. A survey of their dietary habits was also done. The researchers found that there was no link between selenium levels in the blood and the risk of prostate cancer except in those men with a high intake of vitamin E and multivitamins. They concluded that there was no evidence to support the role of selenium supplements in the general male population. Selenium deficiency is unusual in Australia, but men need to be careful if taking selenium supplements as excess amounts can lead to toxicity. The National Health and Medical Research Council recommend a dietary intake of 65μg a day for men, which should be provided by a balanced diet. 1 Peters U, Foster CB, Chatterjee N, Schatzkin A, Reding D, Andriole GL, Crawford ED, Sturup S, Chanock SJ, Hayes RB.
