I have come to believe that surgery is inferior for a GS9 diagnosis. To understand why, read the following article:
For very high-risk (GS9-10) patients, EBRT + BT is superior to surgery or EBRT onlyAs you can see, combination therapy with external beam radiation and brachytherapy and hormone therapy had the best outcomes. 10-yr biochemical recurrence rates were:
84 percent for RP (even though more than half had adjuvant/salvage radiation)
40 percent for EBRT
30 percent for EBRT + BT
Of course, there is higher risk of urinary side effects with the multiple treatments, but the cure rates have proven to be the highest.
I assume Arica Hirsch is offering IMRT with an SBRT boost in her clinical trial. I think it is a good one. The downside is that it's new and unproven as yet. The upside is that it may have a low rate of side effects. Proton therapy has no better outcomes or side effects than any other kind of radiation. Did you talk to Brian Moran? he can deliver the combination therapy that seems to be the most effective.
With surgery, they cannot know in advance what can be spared - that's a decision they make when they get inside - hopefully with a pathologist standing by to look at frozen sections. They also cannot tell you if you will need radiation until after pathology review and probably some PSAs. The poor rates of surgical cancer control for your type of PC (PSA<10 and GS≥8) were echoed in another large recent study, where the 10-yr biochemical recurrence was 64%; and 42% had salvage therapy.
