the St Vincent’s Hospital Prostate Cancer Support Group affiliated with the Prostate Cancer Foundation of Australia LIFEBUOY ISSUE 1 2010 Dear Readers As advertised in our last newsletter Dr Charles “Snuffy” Myers visited Australia in February. During his visit he gave talks in Sydney, Brisbane and Melbourne. I had the opportunity to hear him speak at the Garvan Institute, where there was a sellout crowd of over 300 people. A/Prof. Stricker has written a summary of Dr Myers’ talk which you can find inside, as well as the details of how to purchase the talk Dr Myers’ gave at the Garvan Institue. Jaime Fronzek – an accredited practicing dietician and nutritionist will be a regular contributor to Lifebuoy. She has always had a passion for food and its effect on health. She is particularly interested in the effects that specific dietary and lifestyle factors can have on men suffering with prostate cancer. Jamie follows the recommendations of Dr Charles ‘Snuffy’ Myers due to the success he has had with his patients. In each issue she will bring you updates on healthy eating with a recipe for you to try. Now there will be no excuses not to eat delicious food that is good for you. Our research updates will now also introduce you to the talented researchers working behind the scenes at the Garvan Institute and the St Vincent’s Prostate Cancer Centre. Each newsletter will give you an opportunity to find out about them and their work. On March 18th I attended the PCFA ‘Thank You’ function at Kirribilli House. I had the privilege of being one of five recipients of the Max Gardner award for distinguished service. This award is given by the PCFA to those who have made an outstanding and significant contribution to the cause of prostate cancer in Australia. The other recipients were John Allen, Ron Schmarr, Robert Slade and Con Casey. It was a wonderful evening and I felt very honoured. prostate cancer centre Mr David Sandoe OAM with the Max Gardner Award recipients Jayne Matthews - Coordinator www.prostate.com.au lifebuoy_e1_2010.indd 1 8/04/10 10:29 AM Dr Charles ‘Snuffy’ Myers The talk given at the Garvan Institute to over 300 people. by A/Prof Phillip Stricker 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 (USA) is a medical oncologist, scientist, nutrition expert and prostate cancer survivor. He has over 250 research papers 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. 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 that 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”. 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 patient’s who have hormone therapy where the testosterone is suppressed but the dihydrotestosterone lifebuoy_e1_2010.indd 2 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. 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 drug interactions 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 oncologiist and researcher form 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. 8/04/10 10:29 AM Side effects of hormone therapy The following is a list of the possible side effects of hormone therapy: 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 patient’s 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. 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. Have regular exercise Locally advanced disease There have been improvements in both the staging techniques and treatment of locally advanced disease. Example of advances are: 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. 1. IMRT ( Image Modulated Radiotherapy ) to more accurately target primary and secondary prostate cancer. Maintenance therapy 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). 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 an enormous enthusiasm from the public and 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. 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. 2. MRI to better image the extent of the cancer in the prostate. 3. Combidex MRI and choline CT/PET fusion to more accurately locate the site of lymph node metastases.

At the recent annual meeting of the Urological Society of Australasia in Perth A/Prof Phillip Stricker and Dr Geoff Coughlin were invited to participate in the debate on the above topic against their colleagues from the USA. Here is a summary of their affirmative argument only. A/Prof Stricker explained that having done over 2,600 open radical prostatectomies and over 400 robotic prostatectomies he was in an excellent position to judge whether robotic prostatectomy was offering his patients better outcomes. He noted that his patients were having a quicker recovery, less blood loss and transfusion, less cystogram leaks, less bladder neck contractures, a lower positive surgical margin rate in PT2 cancers, earlier and more complete return of potency, easier to perform technically in some patients such as obese patients or people who have had previous laparoscopic measures for hernia repairs, it was better for him in terms of the comfort during operating and it was a better teaching tool. He also made the point that in more extensive cancers it took him longer to achieve equal outcomes as for his open cases but currently with the experience of having done over 400 cases he has now mastered the ability to not only achieve equal results to his open series but also be able to perform extended lymph gland dissections which are necessary for the higher grade cancers. A/Prof Stricker explained that there has been considerable evidence from the world literature suggesting that the surgeon volume has a direct link to patient outcomes. The learning curve for open surgery and robotic surgery is much longer than initially appreciated and probably is about 250 cases. With these 2 observations he made the conclusion that when comparing the different forms of radical prostatectomy it was mandatory to only compare experienced units and also make sure that the technique of reporting was standardised. Looking at the ‘trifecta’ (i.e. the positive surgical margin rate, urinary continence rates and potency rates), recovery rates and complication rate between the various techniques i.e. robotic, laparoscopic and open surgery it was very difficult to compare these technologies until recently when more experienced robotic units are now starting to report their results. When looking at only centres that have reported their results of greater than 250 cases and reviewing all the literature till April 2009 , Patel et al were able to find 48 articles and when looking at the review of all articles reporting greater than 50 cases from 1996 to 2009 in the lifebuoy_e1_2010.indd 5 world literature the ICER review committee were able to find 70 articles. On reviewing the centres that have performed more than 250 cases and comparing the averages of each technique, the positive surgical margin rate, continence and potency were better for the robotic technique than either the open or laparoscopic. When comparing the 70 articles reporting greater than 50 cases, the PT2 positive margin rate as well as the continence and potency rates were better for the robot compared to the other techniques but with more extensive cancers they were equal (ICER review). Ficarra et al , in reviewing the 10 studies that directly compared robot versus open, there appears to be a benefit for the robot in terms of positive surgical margin rates. A snapshot of approximately 40% of all the prostatectomy cases performed in Australia in 2009 showed that the PT2 positive margin rate was better for the robotic procedure whilst the PT3 positive margin rate was similar between all procedures. In specific regard to potency after robotic or open surgery he referred to the article published by Montorsi et al in Milan who used a validated questionnaire and followed his patients for 24 months and compared his open and robotic results. Montorsi is a highly experienced open and robotic surgeon and he found in his hands the results of nerve sparing surgery seemed to give better results in the robotic arm. With regard to complications the national data presented from Medicare collected in 2003 to 2005 (Hu et al), the results from the Karolinska Institute in Stockholm (Carlson et al) where a more validated prospective collection was used and then some of the major reviews of complications which have been performed by Patel et al shortly to be published in European Urology and ICER which is an institute which reviews data associated with Massachusetts General and Harvard. In looking at this information, robotic radical prostatectomy has less blood loss, less chance of transfusion, less general complications, less chance of bladder neck contracture, shorter length of stay and has less impact on the surgeons from the point of view of neck pain and back pain. Furthermore, the point that it is widely available in the United States and becoming increasingly available in Australia and the growth of the Da Vinci robot appears to be on track to be readily available to most Urologists within 3 to 4 years. As a teaching tool the da Vinci robot is excellent in providing better visualisation, the opportunity for simulation, supervision and video based learning. From the point of view of the future, it readily lends itself to fusion of images such as MRI with operating procedures and also working in concert with the new developments where single holes and normal orifice surgery are developing, this would enable this to become a reality. As with every new technology there are various stages; firstly, the earlier adopter phase where there are increased complications and a longer learning curve; 8/04/10 10:29 AM secondly, where disadvantages are noted but advantages are seen; next the criticism by established users; then overcoming the disadvantages; then the standardisation of technique and the wider availability and finally the establishment of training programs. At this point one can call something the gold standard and I believe robotic radical prostatectomy has reached that point. In summary it appears that robotic radical prostatectomy has advantages over the previous gold standard open radical prostatectomy in experienced hands. The ‘trifecta’ in experienced hands is at least equal to the best open radical prostatectomy series and there are fewer complications, a quicker recovery, lower blood loss, lower anastomotic strictures, improved surgeon economics, reproducibility, a standardised technique, it is widely available, readily teachable and greater potential for future advances. His colleague Dr Geoff Coughlin in rebuttal of the opponents view addressed the argument that there were potentially more complications with the robotic technology as reported by Hu et al in 2009 when he reviewed the Medicare data of America from 2003 to 2005. It became very clear that Hu was comparing an inexperienced group of robotic surgeons to an experienced open team. A further paper by Schroeck et al discussing the lack of satisfaction with robotic surgery was also reviewed. It was noted that in this paper, that the difference between satisfaction rates with open and robotic surgery was not statistically significant. When it came to the cost of the two procedures it was acknowledged that initially cost was more expensive until the volume of cases that went through a unit became high and indeed Dr Coughlin suggested that in a public hospital such as Royal Brisbane Hospital there was significant savings doing robotic surgery compared to open. This was mainly based on the fact that patients went home between 1 and 2 days with the robot and on day 5 with the open. Making A Difference It was also explained that laparoscopy when performed by an expert gives excellent results but it has only been adopted by less than 1% of people in the United States and all the top units are now converting to robotic. It can therefore not be regarded as the gold standard as it is not widely enough adopted. R With regard to open surgery it was noted that this has previously been the gold standard and indeed an excellent open surgeon can overcome most of the difficulties of access bleeding, complications and ergonomics. The problem that is occurring world wide is that the numbers of these cases are declining and this will impact upon training and therefore this will no longer be the gold standard. It was pointed out that most young surgeons are much more likely to take up a robot fellowship than an open or laparoscopic fellowship and therefore this will make robotic surgery more likely to be the gold standard in the future. It was finally noted that one of our opponents from the United States Dr Jeff Caddedu when interviewed in the New York times felt that the battle was lost when it came to robot versus open surgery!

In November 2007 Siobhan Ellis was a patient in St Vincent’s Hospital after an oncoming car did a u-turn in front of her. She suffered a damaged shoulder and a fractured skull - even though she was wearing a helmet! It was after this hospital experience that she decided to raise money for breast and prostate cancer at St Vincent’s and Mater Health. Why cancer research? Siobhan had lost a few friends recently to cancer – specifically, Kirsty Rae and Peter Wherret. Siobhan completed her ride. Well done!

The majority of my degree so far has been grounded in science. Being involved in more practical hospital activities has reinforced my passion for healthcare. My name is Sara Bassin and I am about to embark on my final year of Medical studies after 9 years at university. I began my studies in 2001 at UNSW in Bioinformatics, which I can best explain as a fusion of genetics, molecular biology and computer science. I then undertook a research masters in Bioinformatics and attempted to get into medicine. 3 years on, I couldn’t be more satisfied with my chosen path. I started work at The Garvan Institute of Medical Research in late 2008, in the prostate cancer research group. Specifically I am involved in the prostate cancer quality of life study which looks into the outcomes of patients after treatment and the monitoring of those with high risk of prostate cancer. Being responsible for patient recruitment and management of incoming and outgoing questionnaires for the study has allowed me to be actively involved in the progress of a leading research project, and it has been interesting to see its development from the ground up. Learning about research protocols and study design in this project has not only allowed me to greater appreciate the importance of quality medical research, but has also opened my eyes to just how complicated and involved research is. I have been working with at the Garvan Institute since I started my medical degree in 2007. As I had 2 years experience in scientific research, I was eager to continue to be involved in a research environment throughout my degree. The Garvan Institute provided the perfect opportunity. Since beginning here, my main area of focus has been on the Quality of Life project, comparing quality of life outcomes in different arms of prostate cancer treatment. I have found the work here to be both stimulating and satisfying and am grateful for all the exposure I have gained to the world of medical research. Save the Date !
