Dear a777:
Well, you have initiated a well worn discussion/debate here at HW, i.e. which is better surgery or radiation? You will find no clear concensus here but I will wade in with an assessment of how I would logically look at your decision process, given your stats.
1. Cure Rate. To my knowledge there has been no long term, large scale randomized study of radiation vs. surgery. However, there have been many, many separate and sometimes contradictory studies that detail the long term surgical and radiation cure rates. Despite the confusion, my conclusion is clear...the long term cure rates for surgery and radiation are similar. ADVANTAGE: Neither.
2. location of the Tumor. According to you, there is some indication that your margins may be positive. Reference the above posts by JohnTand BobCape...radiation has a better chance of curing you the first time than does surgery. ADVANTAGE: Radiation.
3. Quality of Life. With surgery you are likely to have immediate incontinence and ED. The incontinence should lessen, the ED may not. You will also likely have a shorter penis, no ejaculate and may ejaculate urine. With radiation you are likely to have short term urgency and frequency that will lessen and may have longer term ED. There is also a small chance of rectal issues. Overall, the long term side effects of sugery include higher rates of ED as compared to radiation. Probably the best QOL comparision that I have seen was done by the New England Journal of Medicine a couple of years ago. It showed much lower declines in sexual satisfaction from radiation patients than from surgery patients. BIG ADVANTAGE: Radiation.
4. Back up Plan. Surgeons have been great at playing on patients fears about having a back up plan, i.e. you can have radiation after surgery but not surgery after radiation. That only tells part of the story even though some posters even on this thread continue to preach that gospel. The fact is that there are multiple salvage procedures for a failed radiation. These include cyrosurgery, seeding with a different isotope, HDR Brachy and salvage HIFU. The success rates for these salvage procedures are as high as for salvage surgery. The bottom line is that you hope there is no need for a salvage treatment but ones are available for either choice. ADVANTAGE: Neither.
5. Knowing your Pathlogy. If you have surgery you have an exact read on your pathology shortly after the operation. With radiation you do not. The real question is what will you do with the information once you have it? There have been debates on other threads about the advantages of starting immediate post-surgery radiation or waiting for PSA rises. If you are of a mind to wait, then having the information is interesting but not critical. If you are of a mind to start immediate radiation if postive margins are noted, then the information is important. ADVANTAGE: Surgery.
6. Psychology. This is highly patient dependent. If you are like me, my mindset was to "get it cured", so I was able to look at the facts fairly logically. However, some men have a mindset to "get it out", in which case emotions rule over logic. Only you can know which kind of guy you are. ADVANTAGE: Neither.
OK, so what would I recommend to you if you were my brother and knowing your stats? I would encourage you to get your biopsy pathology read by a PCa expert, to seek an opinion from a prostate onlcologist, to get a color doppler and then to probably proceed with a combination of seeds and IMRT.
Good luck and please keep us posted,
