SBRT versus IMRT for BCR after prostatectomy

Posted by pamperme @pamperme, 1 day ago

I am 72 years old and had< .02 PSA for two years after my prostatectomy. My PSA went up to .05 then jumped to .15. My onocologist recommended 35 IMRT sessions and I got a second opinion which agreed with radiation but would do 5 SBRT sessions to the pelvic and lymph node area. I am trying to find out advantages and disadvantages of each one.
My decipher score was .92 and I had two locations with no margins and EPE. I am currently on Orgovyx and am on hold since 3 spots of low emissivity showed up on psma/pet test. They are going to take a second test in 10 weeks after being on Orgovyx and if the emisivity stays the same they will determine it is non cancerous and I will go for radiation. If the emisivity disappears then it will be considered cancerous. I do not think the spots are cancerous. My second opinion recommended doing an MRI also. I would appreciate information on SBRT and IMRT for the reoccurence at 3 years. Thank you everyone for all the information I have learned from this site in the past.

@islander2025 You are going to hear many acronyms all for the same thing: EBRT, IMRT, VMAT, IGRT.
They all use programmed treatments based on your simulation visit; all attempt to minimize tissue toxicity, and all need a full bladder and empty rectum.
They usually involve 20-40 sessions depending on the preferences of the RO and your particular needs. Hope that helps,
Phil

It really does look like a great way to do this treatment. I have just never heard of any of the people in all of the meetings I go to discussing the fact that they had it.

I will actually ask about this in meetings To see what people’s results were.

@jeffmarc yeah that would be great I know it’s still not like Proton.. although supposed to be really good I don’t know if the side effects are more.. my RO says not much difference, but to me saving my parts is important if I had the 60-100k they say proton cost I would gladly pay for it 🤣
