The " standardized incidence ratios " for rectal cancer developing after surgery, external beam, brachytherapy, and external+brachytherapy were: 0.91, 0.99, 0.68 and 0.86 respectively.

Guest guest Posted January 9, 2009 Report Share Posted January 9, 2009 Steve, The study to which you refer (the summary of which is attached below for anyone interested) refers to almost quarter of a million men who underwent treatment between 1988 and 2003. Although as you say the data is between five and ten years old, I don’t see how it could be any ‘younger’ given the time taken to assemble it – and given the nature of the cases under review, is that time frame so outrageous? What I found of particular interest was the preamble <snip> Pre-prostate specific antigen era series demonstrated an increased risk of bladder cancer and rectal cancer in men who received radiotherapy for prostate cancer. <snip> Now that is going back a long time, but as long as I have been taking an active interest in PCa this allegedly demonstrated increased risk has been denied emphatically, usually under the general ‘there are no studies’ rule. This of course dos not mean that a situation does not exist, merely that no one has written an acceptable study. But this opening statement now implies that before the PSA testing was introduced there was a demonstrable increase in bladder and rectal cancer and that this study confirms such a potential increase in men diagnosed kin the era after PSA testing was intriduced. It would be no great surprise to me if this were the case. After all we have been told for years that one of the causes of cancer is radiation and there are many theories as to how much radiation cells can take before they are damaged, hence the differing views on dosage for radiation therapy and the fact that once a man has had radiotherapy, he is precluded from any secondary treatment involving radiation because of the accumulated dosage he has received, Like Allan I do not have the statistical skills to try and establish how much of risk is being predicated in this study, but presumably the radiologists who might counsel their patients appropriately will be able to interpret them (or then again, maybe not!!)

Department of Urology, University of Miami School of Medicine, Miami, Florida, USA. alan.nieder@... PURPOSE: Pre-prostate specific antigen era series demonstrated an increased risk of bladder cancer and rectal cancer in men who received radiotherapy for prostate cancer. We estimated the risk of secondary bladder cancer and rectal cancer after prostate radiotherapy using a contemporary population based cohort. MATERIALS AND METHODS: We identified 243,082 men in the Surveillance, Epidemiology and End Results database who underwent radical prostatectomy or radiotherapy for prostate cancer between 1988 and 2003. We estimated the incidence rate, standardized incidence ratio and age adjusted incidence rate ratio of subsequent bladder cancer and rectal cancer associated with radical prostatectomy, external beam radiotherapy, brachytherapy, and a combination of external beam radiotherapy and brachytherapy. RESULTS: The relative risk of bladder cancer developing after external beam radiotherapy, brachytherapy and external beam radiotherapy-brachytherapy compared to radical prostatectomy was 1.88, 1.52 and 1.85, respectively. Compared to the general United States population the standardized incidence ratio for bladder cancer developing after radical prostatectomy, external beam radiotherapy, brachytherapy and external beam radiotherapy-brachytherapy was 0.99, 1.42, 1.10 and 1.39, respectively. The relative risk of rectal cancer developing after external beam radiotherapy, brachytherapy and external beam radiotherapy-brachytherapy compared to radical prostatectomy was 1.26, 1.08 and 1.21, respectively. The standardized incidence ratio for rectal cancer developing after radical prostatectomy, external beam radiotherapy, brachytherapy and external beam radiotherapy-brachytherapy was 0.91, 0.99, 0.68 and 0.86, respectively. CONCLUSIONS: Men who receive radiotherapy for localized prostate cancer have an increased risk of bladder cancer compared to patients undergoing radical prostatectomy and compared to the general population. The risk of rectal cancer is increased in patients who receive external beam radiotherapy compared to radical prostatectomy. Patients should be counseled appropriately regarding these risks.

Guest guest Posted January 9, 2009 Report Share Posted January 9, 2009 Gentlemen we are getting to one of thge inherent difficulties with PCa. It takes time to see the effects of treatment, hence there is a gap where improvements are not taken into account. Techniques in all forms of treatment are being improved but these are not universally applied at the same time as there are delays caused by both cost and training issues - including willingness to train. I think that Terry is saying this is the best info we have - Steve is saying things are improving. I suggest that the effect of treatment improvements is gradual and not sudden - in a year or 5 we will know more.

I'm afraid that that question ranges far afield from the topic, which is whether the study cited upthread is relevant to the concerns of today's patient. I do not claim expertise in the field of radiation therapy, and I'd be surprised if Terry did. And the grandfather referred to by Dr. Rose is probably not literally the father of one of Terry's parents. Nor mine.

Guest guest Posted January 9, 2009 Report Share Posted January 9, 2009 However I think you would have to agree that radiation treatment received in 1988, over 20 years ago, must be fairly irrelevant as a guide for the likely outcomes of treatment given in 2009. The difference in computing power that allows accurate imaging and delivery of radiation in it's various forms must be huge.
