Queensland Prostate Cancer News The magazine is a publication of the Queensland Chapter, Prostate Cancer Foundation of Australia. August 2010 Letter from the Editor, Volunteers are the lifeblood of community organisations. There are high profile volunteer community groups such as Rotary, Lions and Meals-on-Wheels which are well known but there are literally hundreds of other voluntary associations, all doing their bit to identify and address community problems or complementing the efforts of paid workers within charitable organisations. The various Cancer Councils and the Prostate Cancer Foundation of Australia (PCFA) fall into this latter group and the Prostate Cancer Support Groups are the voluntary part of PCFA. smaller shows. Support Group volunteers get free entry to the shows and plenty of time to see all the exhibits. Looking after an awareness stand is not arduous and you do get to meet some really interesting people. If you would like to participate in some of these events and you live in SEQ, could you please ‘phone Alison Bannan at PCFA on (07) 3166 2142. Alison is setting up a volunteers’ register but if you’re on the register and dates, times, etc. do not suit at the time a need arises, there’s no pressure to answer the call. Volunteering came to mind recently when PCFA were trying to get a roster together to look after an awareness booth at the Brisbane Caravan & Camping Show (see Page 9). A couple of new faces plus the usual suspects made up the numbers but as the Show ran for 7 days it took a bit of juggling. Other major expos in SEQ where PCFA have a presence include The International Boat Show and The Truck & Machinery Exhibition plus many more For those of you outside the S.E. corner of the State, why not get in touch with your local Conveners (details on Page 2) and let them know that you’re available if a need arises.

June, 2010. George was the Convener of the Mount Isa Prostate Cancer Support Network, one of the many community roles he was passionate about. The Mount Isa Support Group was relatively new but in “Queensland Prostate Cancer News” earlier this year George wrote, “Our fledgling Group shares the dedication of other Groups to be part of the fight against prostate cancer and all cancer generally. We have just begun but we intend to succeed in our endeavours.” George’s work within the local community through Lions, Rotary and other organisations was legend and carried out with an uncompromising commitment to assist his fellow men and women. In the Queen’s Birthday Honours of 2004 he was awarded the Medal of the Order of Australia with the citation reading “For service to the community of Mount Isa through a range of organisations assisting the ageing and people with disabilities.” Former Queensland Cabinet Minister, Tony McGrady, spoke of George as being “a real gentleman. An achiever and a doer but above all else he was a friend. He was a lovely person who did everything with great passion. Nothing was ever too much trouble for George. He always wanted to achieve, not play the political game in organisations.” Local Mount Isa priest, Father Mick Lowcock, had known George for about 17 years and said that, like clockwork, George would be at Mass every Sunday, adding, “He was a humble man who had done a giant of a job. He was a committed man of the community and a committed man of our parish.” Graeme Higgs, Manager of the Prostate Cancer Foundation of Australia in Queensland, noted that prostate cancer awareness had lost a great ally and praised George’s efforts and enthusiasm in spreading the message to the North West corner of the State. “George touched the lives of many people and he will be sorely missed,” he said. “People of George’s calibre are few and far between.” The many tributes for George that flowed into Mount Isa’s newspaper, “The North West Star”, can be summarised as “a truly magnificent man and a true community hero whose spirit and manner helped so many”. Our deepest sympathy is extended to George’s family and friends for their tragic loss. FDA APPROVES SANOFI-AVENTIS PROSTATE CANCER DRUG The Food and Drug Administration on Thursday approved the first prostate cancer chemotherapy drug found to extend the survival of men who are no longer being helped by other treatments. The drug is called Jevtana and it is made by Sanofi-Aventis in France. The FDA approved Jevtana to treat prostate cancer that does not respond to hormone-deprivation treatments or to docetaxel, the cancer drug most commonly used to fight prostate tumours. Earlier this year, a study showed Jevtana prolonged survival for those patients by 10 weeks. Jevtana was approved for use in combination with the steroid prednisone, which is often used in cancer treatment. In that study, patients who received a treatment regimen including Jevtana lived for about a year and three months after starting treatment. Those who received standard treatment lived for about a year and three weeks. There is hope the drug will have a stronger effect on patients who are not as sick. “Patients have few therapeutic options in this disease setting,” said Richard Pazdur, director of the FDA’s Office of Oncology Drug Products. Sanofi-Aventis said it expects the drug to be available this summer. Jevtana is given by injection. In the study, patients on Jevtana were more likely to have their tumurs shrink than those who were on standard chemotherapy. However no patients in the study experienced a complete remission, or disappearance of all signs of the disease. The FDA said Jevtana’s side effects including decreased levels of infection-fighting white blood cells and lower white blood cell count, anaemia, lower levels of blood platelets, diarrhea, vomiting, constipation, weakness and kidney failure. The FDA has approved two potentially groundbreaking prostate cancer treatments this year. It cleared Dendreon Corp’s immunebased therapy Provenge in April. The agency said prostate cancer is the second most common cancer among men in the U.S. The disease usually occurs in older men. The ruling on Jevtana came more than three months early, as the FDA was sceduled to make a decision on the drug by September 30. The drug was developed under the name “cabazitaxel”. Jevtana is also being reviewed by regulators in other markets, including the European Union. Marley Seaman – Associated Press – 17JUN10. 3 QPCN_August_2010.indd 3 19/07/2010 3:50:03 PM DR CHARLES “SNUFFY” MYERS The St Vincents Prostate Cancer Centre and the Prostate Cancer Foundation of Australia were honoured to welcome Dr Myers to Australia in February. Dr Myers is a U.S.A. medical oncologist, scientist, nutrition expert and prostate cancer survivor. He has over 250 research papers and books published and over 30 years of experience with this disease. He opened the Institute for Diseases of the Prostate in 2001 to provide men with the comprehensive care that saved his life. 4. Finally when a cancer no longer responds to traditional hormones, it was Dr Myers’ opinion that a lot of the cancers simply function on less testosterone or dihydrotestosterone. This led to the theory that complete blockage of testosterone both inside and outside the cells may be an aim for further therapy. Hormone therapy. Dr Myers felt that total androgen ablation had some advantages over single LHRH agonists. He also felt that there are many patients who have hormone therapy where the testosterone is suppressed but the dihydrotestosterone is not suppressed and he believes that further suppression of the dihydrotestosterone in people who are not fully responding may be useful. This would involve the use of “Proscar” or “Avodart”. Second line hormone therapy. Dr Myers strongly believes that the attempt to get a full remission is worthwhile as he believes this is more likely to give one a more durable result. A full remission means no evidence of cancer on all forms of imaging and a PSA of less than 0.01. Dr Charles “Snuffy” Myers in Brisbane, February 2010. Members attending the June meeting of the Brisbane Prostate Cancer Support Network were treated to a film of Dr Myers’ presentation to a Sydney audience during his Australian visit. The Sydney presentation was given at the Garvan Institute and was summarised by Associate Professor Phillip Stricker of the St Vincent’s Prostate Cancer Centre. This summary, which appears below, first appeared in the LIFEBUOY, Issue 1, 2010. Understanding principles of cancer. 1. It is very clear that in 2010 we have a very poor understanding of the method by which cancer is spread. Within any cancer there are cells which cannot spread, cells that generate other cancer cells and stem cells which generate all the cells, which are less than 1% of the overall population. 2. Dr Myers believes that it is necessary to induce a full remission and maintain that remission to gain long-term durable results. This has been seen with other cancers such as leukaemia, testicular cancer and lymphoma. 3. Dr Myers also suggested a long-term remission was still possible if the cancer was not too wide spread – a concept called “oligo metastasis”. His own second line hormone therapy at this stage is a combination of “Ketoconazole”, high-dose estradiol and “Leukine”. The last one unfortunately is very expensive and not available in Australia. He also mentioned that when “Abiraterone” becomes available, this drug has the potential to be safer and have equal, or better, efficacy than “Ketoconazole”. The problem with using “Ketoconazole” is that it needs to be carefully utilised with particular care to druginteractions and the affect on the liver and the need to gradually introduce it and take it regularly every 8 hours. Under the careful supervision of a medical oncologist or urologist this, however, in experienced hands, is safe. High-dose estradiol is also effective but unfortunately increases the risk of DVT and pulmonary embolus and therefore one would need to take Warfarin. Again one would have to be under a careful supervision program of a medical oncologist. With regard to “Leukine” there is evidence from Eric Small, a medical oncologist and researcher from America that this is synergistic and this adds to the treatment of “Ketoconazole” but at this stage unfortunately it is unavailable in Australia and is expensive. “Abiraterone” which is currently in trial in Australia and worldwide appears to have less interactions with other drugs and is a once a day dosage with less side effects. There is hope that if this proves successful in Phase III trials, it will be available in the next couple of years. Side effects of hormone therapy. The following is a list of the possible side effects of hormone therapy: Continued... 4 QPCN_August_2010.indd 4 19/07/2010 3:50:03 PM • Hot flushes. • Depression. • Decreased libido. • Lethargy. • Osteoporosis. • Abnormal liver function tests. • Increased breast size (gynaecomastia). • Hypertension. • Diabetes. • Hypercholesterolemia. Clearly, many of these side effects can be anticipated and managed. It is mandatory that the general practitioner for patients on hormone therapy monitor their blood pressure, blood sugar, bone mineral density, cholesterol, lipids and liver function tests regularly. Furthermore it is important that specific questioning about hot flushes, depression, gynaecomastia, lethargy and libido are asked and addressed. General supportive care. At all stages of prostate cancer it is important to do the following: • Be positive and optimistic. • Use appropriate supplements such as pomegranate, fish oil, lycopene and possibly resveratrol. • Eat a Mediterranean type diet and avoid obesity. • Have regular exercise. • Eliminate vitamin D deficiency. • That any side effects of therapy are addressed such as abnormal liver function tests, osteoporosis and hot flushes. • Ensure that hypertension, diabetes and hypercholesterolemia are well controlled. Locally advanced disease. Generally many of these can be controlled by diet, exercise and counselling whilst others such as hot flushes require treatment such as estradiol topical patches. Other treatments include tablets to prevent or treat abnormal liver function tests, tablets to prevent gynaecomastia, anti-depressants in more extreme forms of depression, ace inhibitors or angiotensin blockers or diuretics to treat hypertension and general emotional supportive and optimistic care. There have been improvements in both the staging techniques and treatment of locally advanced disease. Examples of advances are: Maintenance therapy. 3. Combidex MRI and choline CT/PET fusion to more accurately locate the site of lymph node metastases. Dr Myers believes that once a full remission is achieved in patients with advanced prostate cancer that this needs to be maintained. This can be achieved in his view with the use of eliminating Vitamin D deficiency, a Mediterranean diet, regular exercise, decrease in stress and various supplements such as pomegranate, lycopene, fish oil and possibly resveratrol (the active component of red wine). In the high risk situation he has also trialled the use of “Avodart” or “Dutasteride”, using higher dose resveratrol and even periodic uses of “Leukine”. Much of this data has limited evidence at this stage though is supported by some Phase II trials. In the higher risk situation this would need careful supervision by an experienced physician. 1. IMRT (Image Modulated Radiotherapy) to more accurately target primary and secondary prostate cancer. 2. MRI to better image the extent of the cancer in the prostate. Conclusion. Dr Myers has shown that in many of the patients he has treated, they have performed much better than expected. This may well be due to his therapy. There was enormous enthusiasm from the public at all three meetings throughout Australia and one of the strong points he made was to generate a sense of optimism in all patients and show patients what they can do for themselves to give patients a sense of power over their own disease. He was also very optimistic about the future and some of the new developments and understanding that are occurring.

Over the past six months I have experienced some side-effects from my medications (Cougar Trial Phase II) which have made me extremely tired and lethargic and I am finding it difficult to focus on the tasks ahead. In addition there have been some family matters which have resulted in the loss of a loved one so I’ve came to the conclusion that I need to “step back” and “have some time for myself”. The Council has accepted a recommendation that Leon Matigian act in a caretaker role of Chair until the end of the 2010. Both Daryl Hyland and I have stood down as Queensland representatives on the Support and Advocacy Committee of the Prostate Cancer Foundation of Australia and Leon and Bruce Kynaston were duly elected as our replacements. I will stay on as a Council member and, together with Daryl, will focus on the planning of the Queensland Chapter Conference on 7, 8 & 9 October, 2010. As I reflect back over my time as Chair of the Chapter Council, I do so with a degree of pride. When I first stepped into the position I asked the question “What is the role of the Chapter Council?” Although I had no involvement in the final outcome, I am happy to say that this has now been documented together with the role of the Support and Advocacy Committee (SAC) and SAC Representatives. From day one my vision was to have the Chapter Council become a more efficient and effective body and to strive to have a greater level of accountability, transparency and consultation. In a paper I presented to the Council, “My Vision for 2008”, I highlighted the following: 1. Introduce a framework for the effective operation of the Chapter (a) Roles and responsibilities, (b) Procedures and guidelines. 2. Improve communications to Support Groups and utilize Queensland Prostate Cancer News. (QPCN) as an avenue to keep our members informed about QCC happenings. 3. Identify outreach areas not covered directly by Support Groups and initiate a minimum of 3 new Support Groups every year. 4. Develop a support mechanism including resources and financial assistance for new Support Groups. 5. Provide training to all Support Group co-coordinators and their assistants to better equip them for their role within their Groups. 6. Ensure at least six outreach visits to Support Groups are completed and analysed each year. 7. Awareness - Visit outreach areas to provide information and support for people with prostate cancer, their families and friends. I am pleased to say that most of these areas have been addressed, most with positive outcomes. My view has always been that we represent the members of the Support Groups in Queensland and to carry out our tasks effectively we need to be aware of the views of all stakeholders. Through surveys and Conference Workshops, I believe that we were able to identify those areas that the members considered we should focus on. We set up a number of Task Groups to address such issues as Awareness, Targeting Younger Males and Lobbying, Availability of Speakers for Support Groups, Better Access to the Medical Profession, Research and Vetting of Technical Data, Support Group Teleconference (to maintain an effective communication link to the Support Groups), Chapter Administration, QPCN and Web Administration. All of these Task Groups are functioning and producing outcomes. There has been a great improvement in our communication with the Groups. One area where this is evident is with Daryl Hyland, Deputy Chair of the Queensland Chapter Council and Queensland Support Group Services Coordinator. Through his efforts Daryl has brought a greater togetherness to the Groups, the Chapter Council and the Prostate Cancer Foundation of Australia (PCFA). Likewise, utilizing QPCN by including articles (FOOTENOTES) to communicate with our members has allowed Council and PCFA to inform Groups of the happenings and opportunities that are occurring. I have always fought for the right to plan for our own destiny and the Chapter has now developed its Strategic Plan for the next 3 years. To implement this plan the Chapter has also been granted the right to prepare its own budget and the Strategic Plan provides a framework for that process. Frustratingly, a successful application for a Government Grant that was prepared by others has caused the Chapter to rethink its activities for 2010. Providing support and training to members of the Support Groups has always been high on the agenda. We are very appreciative of the amount of support we receive from Cancer Council Queensland (CCQ) and to ensure that this support is used in a meaningful and timely manner, we have regular meetings with CCQ to plan activities. I have enjoyed my time as Chair of the Council and I hope that I have contributed in some positive way to ensuring that we provide that much needed support to our members of the Prostate Cancer Support Groups in Queensland as well as nationally. I would like to make special mention of my mate Daryl who has been a tower of strength to me over this time. Often we hear the comment “you are not alone” and Daryl has really fulfilled that role for me. In conclusion, I would like to acknowledge the ongoing support that I have always received from my wife and family. Without them I would not have been able to accomplish my goals. May I wish all of you the very best of health for the future. Lionel I. Foote. Retiring Chair, Queensland Chapter Council. Prostate Cancer Foundation of Australia. 6 QPCN_August_2010.indd 6 19/07/2010 3:50:03 PM PROSTATE: FOCAL THERAPY IS POSSIBLE The following is an extract from “Major Advances in Surgical Technique for the Treatment of Genitourinary Cancers” which was published in Cancerforum Vol. 34 No.1 March 2010. The article was prepared by Manish I. Patel (Discipline of Surgery, University of Sydney and Westmead Hospital) and Mark Frydenberg (Department of Surgery, Monash University and Department of Urology Southern Health, VIC) Ed. With increasing screening, the burden of prostate cancer disease which may not pose a significant risk to life expectancy is increasing (1). The therapeutic dilemma for a man diagnosed with low risk prostate cancer lies between the extremes of radical therapy on the one hand and active surveillance on the other. The former maximises the chances of cure at the expense of urinary and sexual morbidity. The latter preserves genitourinary function at the expense of psychological burden, potential for disease progression and economic burden of intensive surveillance. Traditionally, treatment of the whole gland has been the standard of care as there is no natural surgical plane to allow partial treatment. Prostate cancer has also been regarded as a multifocal disease requiring treatment of the whole gland. Recent studies show that between 10% and 40% of men who undergo ORRP have unilateral disease (2). This raises the concept of focal ablation of the tumour focus. It has also been shown that in men with multifocal disease, approximately 80% of tumour foci have a volume of less than 0.5cm, which may represent clinical insignificant disease (3). Active surveillance appears to be a very suitable therapy for men with low risk disease, however, the major limitation is the ability to accurately identify men with significant disease that is going to progress clinically. As a result, the failure rate or intervention rate is approximately 20% in active surveillance series (4). The oncological safety of active surveillance is also not well established, as the follow-up in cohort studies is still relatively short, although recent publications suggest that of those who come to definitive treatment, 50% may subsequently develop biochemical faiure. In addition to this, the potential psychological burden and increased cost of close surveillance may make it less desirable than whole gland treatment by surgery or radiotherapy. Major technological advances allowing focal treatment of the affected parts of the prostate include cryotherapy, high-intensity focused ultrasound (HIFU) and photodynamic therapy. This addresses the dilemmas of the untreated prostate in active surveillance, and does so with minimal side effects, which is the major disadvantage of whole gland therapy. To date only early results of small series from single institutions have been reported. Most series used extended or saturation TRUS biopsy to accurately localise the lesion(s) and exclude contralateral disease (although even with these techniques understaging and undergrading can occur in 20-25% of patients). In a report of hemi-ablation using cryotherapy in 55 men with at least one year follow-up, 95% had stable PSAs and 86% remained potent (5), however seven men had to be retreated due to cancer in the contralateral half of the prostate. Another series of hemi-ablation with cryotherapy, with a mean follow-up of 70 months, reported 93% disease-free survival and 48% potency rate (6). A report on hemi-ablation by Muto, using the Sonoblate 500 HIFU device in 29 men with unilateral disease, demonstrated that at six months, 10% had positive biopsies, however a further 23% had positive biopsies at 12 months (7). There was no significant change in urinary symptom scores measured with the validated International Prostate Symptom Score questionnaire. Erectile dysfunction was not measured in this cohort. Photodynamic therapy involves administration of a photosensitising drug followed by delivery of a specific wavelength of light into the appropriate region of the prostate by transperineal needle, resulting in ablation similar to cryotherapy. It is currently in its infancy, however multicentre trials of focal ablation are being planned. Radiofrequency ablation is also a technology which has been used in ablation of solid organs such as kidney and liver. It is currently in early studies for prostate but will soon be studied for focal ablation. In summary, focal ablation appears to be the middle ground between the untreated tumour of active surveillance and the excessive side effects of whole gland treatment. Cryotherapy and HIFU in very small series, with limited follow-up, do demonstrate some promise, however further studies of all ablation methods are required to determine their real place in prostate cancer treatment. The main barrier preventing adoption of these techniques is effective cancer localisation at the time of biopsy, to ensure that the focal therapy is indeed treating all the cancer present in the gland. 1.

The study assessed over 1,300 men treated with radical prostatectomy, of whom 18% were taking statins.The authors found significant differences between statin users and nonusers at presentation. Men taking statins were more likely to be older (P<.001), have a lower median PSA (P=.04), were more likely to be white (P<.001) and have a higher BMI. Statins reduced disease recurrence rate by 30% (P=.05). However, they were also more likely to have a higher biopsy Gleason score (P=.002). At a median follow-up for statin users of 24 months and 38 months for non-users, biochemical recurrences occurred among 23% of men – 16% of whom were statin users and 25% were non-users. After adjusting for the pathological and clinical factors that differed between the two groups, the researchers found that men who used statins had a 30% decreased risk of PSA recurrence and the association was dose-dependent. “Mounting evidence suggests that statins may influence prostate biology, and although controversial, statins may reduce the risk of advanced prostate cancer,” the study authors said. Given that statins appear to lower PSA levels, one potential explanation is statins merely delay the diagnosis of recurrence, they suggested. They concluded that a randomised controlled trial placing men undergoing radical prostatectomy on statins may be warranted. Cancer 2010;doi:10.1002/ cncr.25308. Nicola Garrett – Oncology Update. Anejaculation Is Likely After Radiation Therapy For Prostate Cancer "Patients frequently present to us after RT for localized prostate cancer with a complaint of anejaculation, and they are often surprised by the onset of this side effect," Doron Stember, MD, a urology fellow at Memorial Sloan-Kettering Cancer Center in New York City, told Medscape Urology. Although anejaculation after RT has not been widely discussed in the medical literature, clinical experience has shown that it is a common complaint after pelvic RT. The scant published data on post-RT ejaculatory function are inconsistent, Dr. Stember noted. For example, a prospective study that used the Brief Sexual Function Inventory (BSFI) found that ejaculatory function sharply decreased to its nadir six months after RT. Ejaculatory function recovered somewhat after this point, but not to its pre-RT level, when the patient was assessed at two years. "While radical prostatectomy is commonly associated with loss of ability to ejaculate, we have shown that, with time, RT also causes anejaculation in a majority of patients. It is important that patients be counselled accordingly prior to treatment." Another study that used the BSFI in post-RT patients found that a significant decrease in ejaculatory function occurred in the first two years after RT, but was found to have stabilized at the four-year assessment point. The BSFI is a popular tool for assessing male sexual function, Dr. Stember noted. Dr. Stember presented the results of a study that examined the ejaculation profiles of men who underwent RT for prostate cancer. John P. Mulhall, MD, is senior author of the study. He is the director of the Male Sexual and Reproductive Medicine Program at Memorial Sloan-Kettering Cancer Center. The study involved 364 consecutive men who provided information regarding their ejaculatory function and orgasm as a routine part of their sexual health evaluation for post-RT sexual problems. Patients completed the widely validated International Index of Erectile Function (IIEF) questionnaire at follow-up visits, starting with the first post-treatment visit, and attention was paid to the orgasm domain on the IIEF. "Anejaculation is an inevitable and well-recognized sequela of radical prostatectomy and may represent a significant source of bother and sexual dissatisfaction," he pointed out. "Loss of ejaculation or a severe decrease in ejaculate volume has been associated with a self-reported deterioration in sexual activity." Overall, 72% of men lost their ability to ejaculate in an antegrade fashion after prostate RT by their last visit. A total of 16% reported anejaculation at one year, 69% at three years, and 89% at five years. "The proportion of men experiencing this side effect increases over time, and men do not recover their ability to ejaculate," Dr. Stember said. Continued... Nearly 90% of men who undergo radiation therapy (RT) for prostate cancer will eventually develop anejaculation, researchers reported here at the American Urological Association 2010 Annual Scientific Meeting. Of the study cohort, 252 men underwent external-beam radiation therapy and 112 underwent brachytherapy. The mean age of the study population was about 65 years, and the mean length of follow-up after RT was about 6.5 years. 8 QPCN_August_2010.indd 8 19/07/2010 3:50:03 PM Risk factors for anejaculation at three years included higher RT doses, older age, exposure to androgen-deprivation therapy, and smaller prostates at the time of RT. Further analysis revealed that orgasm domain scores on the IIEF questionnaire decreased markedly during follow-up. "Since radical prostatectomy always causes anejaculation, some men may choose RT with the false expectation that they will retain their ejaculatory function. That's why we need to inform them beforehand of this potential side effect, just as we do with men undergoing surgery." "It's important that men who are selecting a treatment for prostate cancer be aware of the high likelihood of anejaculation with RT," Dr. Stember advised. Jill Stein – Medscape.com – 10JUN10. QUEENSLAND CARAVAN CAMPING & TOURING HOLIDAY SHOW From the 9th. to the 15th. June the Queensland Caravan Camping & Touring Holiday Show was the happening event at the RNA Showgrounds in Brisbane. Prostate Cancer Foundation of Australia (PCFA) was there to spread the word about prostate cancer awareness to the approximately 80,000 show visitors, including the many “grey nomads” who are entering or are in the prostate cancer problem age and are increasingly taking that “round Australia” adventure in retirement, by either caravan or motorhome. To give an idea of the camping and caravanning surge in Queensland, this year’s show recorded sales by exhibitors of about $50 million. It’s a growth industry and expected to keep on growing as the percentage of the population in the older age groups increases. For PCFA, having adequate staff on hand during the 7 days of the Show to answer questions and distribute information leaflets could not have happened without the support of volunteers and, in this regard, the staff of PCFAQueensland were ably assisted by John Cummins, Ross Davis, Bill McHugh, Bob Perren, Euan Perry, Ian Smith, Bob Adamson John Stead, Garth Stephens and Paul Travers. Over the seven days of the show the PCFA “Shop” gave out countless numbers of prostate cancer information sheets and conducted hundreds of face-to-face discussions about this disease. Bob Adamson (l) and Ross Davis mind the “shop”. TOP 10 THINGS WOMEN SHOULD KNOW ABOUT PROSTATE CANCER Women Against Prostate Cancer (WAPC), a prostate cancer support group geared towards helping women and families affected by prostate cancer, wants to make sure every woman knows the facts about the disease. Below are the top 10 things women should know: 1. What is a prostate? The prostate is a walnut-sized male gland that contributes to the fluid that carries sperm. It is located just below the bladder. 2. What is prostate cancer? Prostate cancer occurs when a group of cells begins growing abnormally out of control in the prostate and invades healthy tissue. The cancer cells may also spread from the prostate to other parts of the body. 3. Who does it affect? Prostate cancer does not only affect men; the disease can have a devastating effect on entire families, especially wives and partners. 4. Who is at risk? According to the National Cancer Institute, one in six men will be diagnosed with prostate cancer in their lifetime. About 20,000 Australian men will be diagnosed this year and around 3,300 will die from the disease. 5.What are the risk factors? While the exact cause of prostate cancer is still unknown, there are dynamics that can increase a man’s risk of getting prostate cancer including: Age: A man’s chance of developing prostate cancer increases quickly after age 50. Family History: Those with a father, brother, uncle or other male blood relative who has had prostate cancer are at increased risk. Continued... 9 QPCN_August_2010.indd 9 19/07/2010 3:50:03 PM TOP 10 THINGS WOMEN SHOULD KNOW ABOUT PROSTATE CANCER Continued... 6. What are the sign and symptoms? Early-stage prostate cancer typically has no symptoms. Therefore, in addition to regular checkups, a man should see a health care provider if he experiences persistent hip or back pain, has difficulty urinating, feels pain and/or a burning sensation during urination, or has blood in his urine. 7. How is it caught early? The most common early detection methods include a digital rectal exam and a prostate-specific antigen (PSA) blood test. Abnormalities may indicate the need for further testing. WAPC recommends that at age 40 (35 for high-risk men) men receive a baseline PSA and digital rectal exam, and speak with their physician about annual screening thereafter. 8. What are common treatment options? Depending on the individual, there are several possible treatment options, each with a different side-effect profile. The most common treatments include prostatectomy (surgical removal of the gland), radiation therapy, hormone therapy and active surveillance among others. 9. What can women do to help? Gently remind him to get a prostate screening. If that doesn’t work, pick up the phone and make an appointment. Early detection leads to the greatest outcomes and an improved quality of life.Stand by your man. If your husband or partner is diagnosed, show support by attending doctor’s appointments or support group meetings with him.Research. As mentioned above, when it comes to treatment options, the choices are numerous. Learn all you can about each treatment, its side-effect profile and expected outcomes, and share what you learn with your partner.Seek support. Connect with other women who are facing the same challenge. Join a local Partners of Men With Prostate Cancer Group for support, and to continue the fight against prostate cancer. 10. What is the survival rate? While there is much work to be done to end this disease, there is hope. If detected early, prostate cancer is highly treatable. To that end, according to the American Cancer Society, the five-year survival rate is nearly 100%. CancerTreatmentPro.com 22FEB10. WHAT EVERY MAN NEEDS TO KNOW ABOUT PROSTATE HEALTH While it may be a sensitive subject for many men, prostate health is one of the keys to their overall well-being, not to mention their families’ future. According to the American Cancer Society, about one in six American men will be diagnosed with prostate cancer, the most commonly diagnosed cancer (other than skin cancer) among this group. Fortunately, there are several ways men can keep their prostates healthier, minimise the risk of prostate cancer, detect it earlier and treat it more effectively. “At no point in the past decade have there been more options for the diagnosis, treatment or management of prostate cancer,” says Virgil Simons*, founder and president of the “The Prostate Net”, an organisation educating men about prostate health. “Most prostate cancer-related deaths are due to advanced disease, which can be minimised through early detection and targeted educational efforts.” Just a few simple tips can help men stay healthier: Get Tested – Every man over the age of 50 should have his prostate examined regularly and receive an annual PSA test, an exam that detects antigen in the blood. High levels of this antigen could indicate a prostate problem that isn’t necessarily cancer, necessitating further study. Those with a family history of prostate cancer or who are at higher risk should begin testing earlier. “Despite the recent controversy regarding the PSA test, no other protocol is available to help measure the potential diagnosis or disease progression of prostate cancer,” stresses Simons. Keep a Family Medical History – Collecting information about the health of family members can show your doctors which ailments to look out for. You should record things like gender, date of birth, diseases or medical conditions and the age when conditions were diagnosed. This information also can be collected through family trees, old letters and obituaries. Watch That Diet – The American Association for Cancer Research has established that weight gain and obesity, especially among inactive men, can increase the risk of prostate cancer occurrence. So, proper diet and exercise are critical. Experts recommend five or more servings of fruit and vegetables a day, particularly greens high in vitamin C content like bell peppers, broccoli, snow peas or cauliflower. Foods high in zinc, like oysters, crab, duck, lamb and lean beef, also can help. Lycopene-containing foods such as tomatoes and watermelon have many cancer fighting properties, as do fish, like salmon, that are rich in Omega-3 oils. Get Educated – Despite having so much information about health, there is still misunderstanding about disease, particularly cancer. In Australia there is a wealth of free information about prostate cancer, cancer generally and men’s health, available from such organisations as the Cancer Council, the Prostate Cancer Foundation of Australia (PCFA) and Andrology Australia.

All my life I have been involved in more than my fair share of physical sports, both socially and at a representative level. For the past 35 years I’ve taken a host of vitamins, eaten all the healthy foods that you are supposed to eat and generally taken care of the body and mind. So when I had my annual medical, including various blood tests, a month before retiring in December 2005 and the results showed that my PSA was greatly elevated compared to the previous year’s figure, I was disturbed to say the least. Further testing confirmed the diagnosis of prostate cancer and the results actually scared the piss out of me. “WHAT RIGHT HAS CANCER GOT INVADING MY BODY”, “THERE IS JUST NO WAY I AM HAVING ANY PART OF THIS”, “YOU NEED TO DO ANOTHER TEST”, etc. etc. These are the sorts of things that passed through my mind and I was having trouble coming to grips with the whole testing procedures and outcome. On retirement in February 2006 my wife and I had everything planned and organised to head off on our trip of a lifetime around Australia in our vehicle and caravan. With cancer raising its ugly head we discussed either re-organising our plans or “BUGGER THE CANCER” and continue on with our trip. I had the final call and it was “BUGGER THE CANCER”, we’re going to head off. So armed with a supply of hormone therapy to take whilst traveling and with instructions to monitor my PSA levels every 3months while we were on the road, which I did, we set off. We traveled for 10 months and had a most enjoyable and memorable trip, perhaps slightly dampened by the knowledge that when we got home I had to deal with a problem and make decisions in an area I was unfamiliar with. Choosing a preferred surgeon, method of treatment, side-effects following treatment, how long would the chosen treatment last, what happens to my wife and family if everything goes pear shaped. Both during and after treatment my mind was in overdrive and making the so-called “correct decision” was extremely difficult. With insistence and assistance from my wife, our son and both daughters the radical was the chosen therapy but even with this treatment I had to get my head around the fact that “erectile dysfunction” would possibly become the norm. there were procedures available to overcome possible side-effects which could be carried out post-radical didn’t help. At that time I felt both extremely angry and disillusioned. Nevertheless the radical it was to be and that was carried out prior to Christmas 2006, with the outcome a resounding success, thanks to an exceptional surgeon. Eighteen months on all was well except for one thing. It became time to address my concerns about erectile dysfunction. Like many others in this situation I had tried medication without success and then a vacuum pump which was only marginally successful. Injections were the next step, an idea I found very daunting to say the least. After getting over the psychological hurdle injections posed I eventually tried but, again, had only marginal success. I had further discussions with the original surgeon and it was decided to opt for a “penile implant”. This was carried out in July 2009 and the operation went well. As would be expected, post-op my nether regions were a bit tender for a couple of weeks but the initial pain and discomfort soon disappeared and all was well. To date the implant has been a great success. Since having the implant I’ve discussed the operation and results with a number of other men who have had this procedure and all of them talk in positives. All are happy that they had the implant which has enabled them to put physical intimacy back into their relationships with their partners. In December it will be five years since my diagnosis and my progress has been monitored with annual PSA tests – SO FAR SO GOOD!! FELLAS – do not hesitate in having your annual PSA tests, preferably accompanied by a DRE. Without having these tests you may never know that you have Prostate Cancer - UNTIL IT IS TOO LATE!! John Cummins. (John Cummins was one of the founders of the Gold Coast Central Prostate Cancer Support Group. For any man considering a penile implant to correct erectile dysfunction who would like to speak to a “user” prior to taking the plunge, John would be happy to talk to you. He can be contacted by ‘phone on 0418 893 850 – Ed.). Although the cancer would probably be eradicated the final outcome had my head spinning. Assurance from my chosen surgeon that Men Prefer Online Screening Decision Aids Most men with a family history of prostate cancer prefer an online form of screening decision aid (DA), research shows. While acknowledging the current controversy surrounding the benefits and harms of prostate cancer screening - mainly the high risk of false positive PSA test results and over–detection of prostate cancers - the present study noted that research indicated that men with a family history of prostate cancer had “significant unmet information needs”.The study authors and designers of the DA, from centres around Australia, recruited eligible men through relatives attending urology outpatient clinics and asked them to appraise a paper-based version of the questionnaire (n=22). The same men were then asked to reflect on an interactive web-based version via a semi-structured phone interview (n=20). The researchers found that both forms of the DA were evaluated positively and all participants found the online DA easy to use and navigate. Most participants (70%) reported that the website was their preferred mode of receiving prostate cancer screening information. “DAs are designed to assist patients with decision making and or risk management options... online DAs have the additional advantage of being able to be tailored to the individual: this is particularly important when risk estimates depend on the number and age of relatives with prostate cancer,” the authors concluded.

The Real Learning Curve for One Surgeon Over Three Years Department of Urology, St Vincent's Private Hospital, Darlinghurst, Sydney, NSW, Australia. Abstract - Study Type - Therapy (case series) Level of Evidence 4. OBJECTIVE To critically analyse the learning curve for one experienced open surgeon converting to robotic surgery for radical prostatectomy (RP). PATIENTS AND METHODS - From February 2006 to December 2008, 502 patients had retropubic RP (RRP) while concurrently 212 had robot-assisted laparoscopic RP (RALP) by one urologist. We prospectively compared the baseline patient and tumour characteristics, variables during and after RP, histopathological features and early urinary functional outcomes in the two groups. RESULTS - The patients in both groups were similar in age, preoperative prostate-specific antigen level, and prostatic volume. However, there were more high-stage (T2b and T3, P= 0.02) and -grade (Gleason 9, P= 0.01) tumours in the RRP group. The mean (range) operative duration was 147 (75-330) min for RRP and 192 (119-525) min for RALP (P < 0.001); 110 cases were required to achieve '3-h proficiency'. Major complication rates were 1.8% and 0.8% for RALP and RRP, respectively. The overall positive surgical margin (PSM) rate was 21.2% in the RALP and 16.7% in the RRP group (P= 0.18). PSM rates for pT2 were comparable (11.6% vs 10.1%, P= 0.74). pT3 PSM rates were higher for RALP than RRP (40.5% vs 28.8%, P= 0.004). The learning curve started to plateau in the overall PSM rate after 150 cases. For the pT2 and pT3 PSM rates, the learning curve tended to flatten after 140 and 170 cases, respectively. The early continence rates were comparable (P= 0.07) but showed a statistically significant improvement after 200 cases. CONCLUSIONS - Our analysis of the learning curve has shown that certain components of the curve for an experienced open surgeon transferring skills to the robotic platform take different times. We suggest that patient selection is guided by these milestones, to maximize oncological outcomes.

NEW ABIRATERONE STUDY Abiraterone Acetate, Prednisone and Leuprolide Acetate or Goserelin Before and During Radiation Therapy in Treating Patients With Localised or Locally Advanced Prostate Cancer. Fred Hutchinson Cancer Research Center, based in Seattle, are currently recruiting participants for a Phase II trial of Radiation with androgen deprivation. Participants will receive abiraterone acetate, prednisone and LHRH agonist prior to and concurrent with radiation therapy. The primary objectives of the trial are to evaluate the safety of abiraterone and prednisone with LHRH agonist given as neoadjuvant and concurrent therapy with external beam radiation in patients with localised prostate cancer and to determine whether pharmacologic suppression of the prostatic androgen axis by inhibition of androgen production with abiraterone can decrease tissue androgen levels to below those observed with GnRH agonist suppression of testicular androgens. Patients will receive oral abiraterone acetate and oral prednisone once daily for 24 weeks and also receive leuprolide acetate or goserelin , given subcutaneously, in weeks 1 and 13. External beam radiotherapy will start in week 15 and continue for 8.5 weeks. The treatment will be ongoing for the 24 weeks in the absence of disease progression or unacceptable toxicity. After completion of the study treatment patients will be followed up every 3 months for 5 years. Secondary objectives of the trial are to determine whether treatment with abiraterone acetate with LHRH agonist will be more effective than LHRH agonist with bicalutamide in inducing inhibition of androgen-regulated gene expression and increased apoptotic cell death as assessed by immunohistochemistry, cDNA microarray analysis and RT-PCR and to evaluate time to PSA progression in patients treated with LHRH agonist with abiraterone acetate.

HIGHER VITAMIN K INTAKE TIED TO LOWER CANCER RISKS People with higher intakes of Vitamin K from food may be less likely to develop or die from cancer, particularly lung and prostate cancers, than those who eat relatively few Vitamin K containing foods, a new study suggests. The study, reported in the American Journal of Clinical Nutrition online 24MAR10, appears to be the first look at the association between Vitamin K intake and the risk of developing or dying from cancer in general. A previous report had linked it to lower prostate cancer risk. The findings do not prove that consuming more Vitamin K helps lower the risk of certain cancers. But they lay the foundation for future studies to try and answer that question, according to Dr Jakob Linseisin and colleagues at the German Cancer Research Centre in Heidelberg. (Vitamin K is chiefly found in leafy green vegetables such as spinach, cabbage, kale, cauliflower, broccoli, brussels sprouts and parsley. Some fruits such as avocado and kiwi fruit are also good sources – Wikipedia – Ed). Reuters Health. 12 QPCN_August_2010.indd 12 19/07/2010 3:50:04 PM Short Cuts Untreated Prostate Cancer No Death Sentence 18JUN10 NEW YORK (Reuters Health) – Even without treatment, only a small minority of men diagnosed with early-stage prostate cancer die from the disease, Swedish researchers reported. Drawing from a national cancer register, they estimated that after 10 years prostate cancer would have killed less than three percent of these men. The study was published in the Journal of the National Cancer Institute online 18JUN10. Outlawed Insecticide Linked to Prostate Cancer 21JUN10 Exposure to the long-banned organochloride insecticide “chlordecone” may be associated with a greater chance of developing prostate cancer, a new case-control study showed. The findings were reported online in the Journal of Clinical Oncology. On the front foot over cancer The Federal Government has highlighted measures to fight what it calls a “worrying” rise in cancer. The Health Minister, Nicola Roxon, has released – a day early – health statistics showing that 115,000 Australians are expected to be diagnosed with cancer this year – a ten percent rise on four years ago. “Although survival rates have improved significantly for many cancers in the past twenty years, cancer is still placing an intolerable burden on our community,” M/s Roxon said of the figures from the Australian Institute of Health and Welfare, to be released formally today. Sydney Morning Herald 23JUN10. Breast, prostate cancer due to same gene 28JUN10 – Hereditary breast and prostate cancer may be two sides of the same coin, new research suggests. Scientists have discovered that both diseases develop the same way in men and women with a faulty BRACA2 gene. The gene, which is involved in DNA repair, is known to play a role in breast, ovarian and prostate cancers. Researchers funded by the Cancer Research UK charity pinpointed cancer-causing DNA defects in male mice genetically engineered to lack BRACA2 in their prostate glands. The research was reported in the online journal Public Library of Science Genetics. Depression often overlooked in cancer patients 29JUN10 ABC Online – Many doctors are failing to recognise the effects that breast and prostate cancer have on a patient’s mental health, according to a recent study. Radiation oncologist David Christie collaborated with the University of New England and Bond University to research the link between cancer and mental illness in 1,000 patients across South-East Queensland. Genomic Analysis of Prostate Cancer Created – In what its creators call a “unique public resource for the cancer research community”, a genomic analysis of prostate cancer is now available online. The immediate significance of this resource stems from the fact that the disease has a “high prevalence” and there is a “relative paucity of large comprehensive genomic datasets in prostate cancer”, according to the authors of a review of the analysis published online 24JUN10 in Cancer Cell. With bad news, families often don’t trust docs 30JUN10 (Reuters Health) – Families of critically ill patients may often take a more optimistic view of their loved one’s condition than doctors do, even when they are given a specific estimate of the chances of survival, a new study suggests. A number of studies have found that doctors and family members frequently have different opinions on critically ill patients’ odds of survival. This raises the question of whether doctors are effectively communicating their estimates of patients’ prognosis, that is, the course their disease is likely to take. So for the new study, researchers looked at whether the numeric and qualitative approaches differed in their effects on families’ views. The findings were reported in the American Journal of Respiratory and Critical Care Medicine. Rate ratio of death from prostate cancer in men attending screening versus controls was 0.44 01JUL10 (HealthDay News) – A prostatespecific antigen (PSA)-based screening program is associated with a reduction in prostate cancer mortality of nearly half over 14 years, but with a substantial risk of over-diagnosis, according to research published online in The Lancet Oncology. Above Information Sourced from Cancer Daily News. PROSTATE CANCER PATIENTS FACE RATIONING OF “PROVENGE” In April 2010 the U.S. Food and Drug Administration (FDA) approved the use of Provenge for the treatment of “asymtomatic or minimally symtomatic metastatic, castrate resistant prostate cancer.” Provenge is a therapeutic vaccine and the first of a new class of drugs known as autologous cellular immunotherapies. Due to limited manufacturing capacity for Provenge only about 2,000 patients can be treated in the first year, falling well short of the 100,000 patients with advanced tumours who may be eligible to receive the drug. Tom Randall – Bloomsberg Businessweek – 28JUN10. TOMOTHERAPY COMES TO QUEENSLAND The Royal Brisbane and Women’s Hospital is currently installing Australia’s first Tomotherapy unit. This unit combines integrated CT imaging with conformal radiation therapy delivered via a linear accelerator. It differs from the usual whole-of-tumour delivery of radiotherapy in that the radiation is delivered “slice-by-slice”, accurately pinpointing the tumour and sparing surrounding healthy tissue. The prefix “tomo” is the Greek for “slice”. Once installed the unit will be able to treat around 20 patients per day. 13 QPCN_August_2010.indd 13 19/07/2010 3:50:04 PM DOGS SNIFF OUT PROSTATE CANCER - Approach Associated With Few False Positives in Early Testing Dogs may be able to sniff out the smell of chemicals released into urine by prostate tumours, setting the stage for a new means of early prostate cancer detection. In early tests, the approach produced fewer false positives than would be expected with the commonly used PSA test, French researchers report. The concept isn’t new. Other researchers have reported varying degrees of success using dogs to detect cancers of the skin, lung and bladder, says researcher Pierre Bigot MD of Tenon Hospital in Paris. The theory is that many tumours release chemicals with distinct odours that can be picked up by dogs, whose sense of smell is much more sensitive than that of humans, he tells WebMD. Better Prostate Cancer Tests Needed More accurate prostate cancer tests are sorely needed, says Anthony Y. Smith MD, chief of urology at the University of New Mexico in Albuquerque. While the widely used PSA test picks up a lot of cancers, it also has a high false-positive rate, he tells WebMD. “If all the men with high PSA scores go on to have biopsies, fewer than one-third will actually have cancer,” Smith says. “Plus, many men with early prostate cancer are unnecessarily treated because existing tests can’t distinguish between lifethreatening and slow growing tumours,” he says. In the United States, one man in six will receive a diagnosis of prostate cancer during his lifetime, but a much smaller proportion – one in thirty-five – will die from the disease, according to the American Cancer Society. Smith moderated a news briefing on the findings at the American Urological Association annual meeting. Dogs Sniff Out 63 of 66 Prostate Cancer Samples For the new study, researchers led by Jean-Nicolas Comu MD, also of Tenon Hospital, trained a Belgian Malinois – a shepherd breed used for detecting bombs and drugs – to identify urine from patients with confirmed prostate cancer and then to discriminate those samples from urine of healthy men. After about a year of training, the dog was put to the test. During 11 runs, the dog faced six urine samples, only one of which came from a man with prostate cancer. Its mission: To sit in front of the urine it considers cancer. In 66 tests, the dog was correct 63 times. There were three false positives, in which the dog mistakenly identified samples from healthy men as being cancerous. And there were no false negatives. And one of the three false positives might not have been that false; when the man who provided the urine sample had another biopsy, he turned out to have prostate cancer, Bigot says. Other dogs are now being trained. ‘Electronic Nose’ for Prostate Cancer Detection. The low false-positive rate “is pretty spectacular,” Smith says. “But this is a very small study and it remains to be seen if the findings will hold up in other studies. Sceptics are concerned that the animals may be picking up on subconscious signals from researchers among other things. The next step is to figure out what chemicals or combination of chemicals the dog is sensing.” If the approach does pan out, don’t look for dogs running around hospitals, sniffing urine samples. That would be impractical and prohibitively expensive, Bigot says. But if researchers can identify which chemical the dog is reacting to, they hope to develop an “electronic nose” for more accurate prostate cancer detection. Charlene Laino – WebMD.com – 02JUN10. SPONGE COULD HOLD PROSTATE THERAPY British Columbia scientists have developed an experimental new drug to shrink prostate cancer tumours, based on molecules extracted from a marine sponge collected in New Guinea. Their study, published today in the journal Cancer Cell, shows the experimental drug, “EPI-001”, not only shrunk tumours, but did so without toxic effects on the cancer-afflicted laboratory mice that got injections of the drug. “The day I saw the way tumours were actually shrinking, I ran all around the building showing everyone the pictures,” said Marianne Sadar, a scientist with the British Columbia Cancer Agency. Sadar has spent years looking for new drugs to help men who suffer from relapses when their cancer becomes resistant to androgen ablation therapy: surgical or drug treatment meant to stop production of male hormones (testosterone) that fuel tumour growth. Continued... 14 QPCN_August_2010.indd 14 19/07/2010 3:50:04 PM In such men, prostate cancer begins to grow again and standard therapies may increase survival by only about two months, according to the new study. Several years ago, Sadar teamed with Raymond Andersen, a natural compounds chemist and University of British Columbia professor, who has spent much of his career combing the seas for natural compounds to be used as anti-cancer medicines. Sadar said there have been a number of chemotherapy drugs developed from sponges. And a survey by the U.S. National Cancer Institute showed that natural products or synthetic versions of natural products make up about 64 percent of anti-cancer compounds currently in pre-clinical studies or clinical trials. More than 70 percent of the Earth’s surface is covered by oceans and it’s been estimated there are more than 100,000 species of invertebrates in the oceans. Sponges are considered ideal for providing raw materials for the development of new drugs. But in a surprising turn of events, scientists discovered that the compounds in the marine sponge had a chemical composition resembling a compound called BADGE (Bisphenol A Diglycidic Ether), which indicated the sponge was harvested from contaminated water possibly polluted by ship traffic. Sadar said sponge material was collected from a shipping route and it would appear the sponge “bioaccumulated the metabolites or byproducts of Bisphenol A,” a ubiquitous compound used in the plastics industry. Bisphenol A (BPA) is the subject of concern, as research has shown it can be an endocrine system disrupter and may be especially harmful to infants and children. Sadar said her team isolated and extracted only the sponge’s desired compound, EPI-001, into a purified form and then synthesised it. The drug does not contain BPA and, indeed, in the study, mice getting high doses of EPI-001 suffered no ill effects on their internal organs as shown by pathologic examination. Future studies must satisfy Food and Drug Administration guidelines before being used in humans in clinical trials. Pamela Fayerman – The Montreal Gazette – 21JUN10. NEW NEOADJUVANT MAY RENDER ADVANCED PROSTATE CANCER OPERABLE Ipilimumab (also known as MDX-010 or MDX-101) is a human monoclonal antibody being developed by Bristol-Myers Squibb and Medarex. It is intended to be used as a drug to activate the immune system. Ipilmumab binds to CTLA-4 (cytotoxic T lymphocyteassociated antigen 4), a molecule on T-cells that is believed to play a critical role in regulating natural immune responses. The absence or presence of CTLA-4 can augment or suppress the immune system’s T-cell response in fighting disease. Ipilimumab is designed to block the activity of CTLA-4, thereby sustaining an active immune response in its attack on cancer cells. As neoadjuvant therapy, ipilimumab appears to boost T-cell responses in patients with advanced prostate cancer receiving androgen ablation therapy. In a randomised phase II study at the Mayo Clinic and Memorial Sloan-Kettering Cancer Center, more patients on ipilimumab showed a decline in PSA to undetectable levels. Some had a significant clinical response with disease downstaging. A further study of 12 patients who opted for radical prostatectomy showed a “profound” local response among those in the ipilimumab arm: disaggregation of solid tumours into isolated organ-confined foci potentially amenable to resection. This combined therapy “may have significant implications for improving prostate cancer treatment,” the researchers say.

As the most common cancer and the second leading cause of cancer death in Australian men, prostate cancer is an important issue. Until now, there has not been a dedicated service focused solely on delivering information regarding the pros and cons of prostate cancer testing. The screening service offers easily accessible and simplified testing for prostate cancer by highly trained medical practitioners in a specialised primary care framework. “The sole focus of the consultation at Prostate Screen Queensland is discussion and education regarding prostate cancer testing and early diagnosis. Informed decision making is vital,” Dr Swindle, developer of Prostate Screen Queensland, said. Prostate Screen Queensland will be situated at the Mater Private Clinic, South Brisbane.

Patricia and I were sitting at the breakfast table last Sunday reading the papers when an article about a young widow remarrying caught my eye. “If I was to die suddenly I want you to immediately dispose of all my stuff, either sell it or give it to Vinnies,” I said. “Now why would you want me to do that?” she said. “Because I guess you’d remarry and I don’t want some silly old bugger using my things.” She gave me a quizzical look and said “What makes you think I’d marry another silly old bugger?” 16 QPCN_August_2010.indd 16 19/07/2010 3:50:04 PM
