Is EBRT effective for right pelvic bone prostate cancer? What are the side effects?

[tarzantass]

please let me know your experience as to side effects. Is it a good ideal to use EBRT for the right pelvic bone prostate cancer? So far I have had no bone pain.

[Magnus1964]

I had salvage radiation for hip bone met 9 years ago. No problems since.

[tarzantass in reply to Magnus1964]

Thanks. By the way, is salvage radiation the same as EBRT?

[Magnus1964 in reply to tarzantass]

Yes, it is just directed at different area from EBRT to the prostate.

[tarzantass in reply to Magnus1964]

Thanks, Magnus

What’s the percentage like for getting secondary cancer after the initial radiation? Is it a myth or truth about getting secondary cancer from the first radiation?

[Magnus1964 in reply to tarzantass]

With salvage radiation you are not radiating the same spot, so this is not a problem.

Thanks, Magnus

How many bone metastases?

You should be taking Zytiga instead of Casodex.

[tarzantass in reply to Tall_Allen]

From the bone scan done more than a month ago, one area that is the right pelvic (illiac) area.

[Tall_Allen in reply to tarzantass]

How many ever?

[Tall_Allen in reply to tarzantass]

No one knows for sure, but it's probably on the order of 1 in 1000- less with highly accurate SBRT. Not a concern for you.

[tarzantass]

At the start of diagnosis in 2016, bone Mets in right femur, pelvic lymph node and pelvic bone were found. Femur lesion and lymph node were gone in recent scans.

[Tall_Allen in reply to tarzantass]

So two bone metastases? If safe, why not irradiate them?

[tarzantass in reply to Tall_Allen]

Thanks, Allen

I have had SBRT on three occasions: Oct 2022 on prostate and left ischium metastasis (5 x 7 Gys on prostate and 5 x 5 Gys on bone met); Feb 2023 on two new mets on mid sacrum and right acetabulum (5 fractions of 25 Gys). No side effects to speak of, except perhaps a bit of increased urination (which did not last very long). Mets decreased in size. June 2023 radiation on right hip to relieve pain caused by mets (which successfully treated the pain).

[tarzantass in reply to Hidden]

Were the two new Mets (Feb 2023) you mentioned secondary cancer? What’s the percentage like for getting secondary cancer after the initial radiation? Is it a myth or truth about getting secondary cancer from the first radiation?

[Seasid in reply to tarzantass]

I believe that you would probably need more time to develop a secondary cancer after the initial radiation therapy. Why don't you ask your doctor about this?

[AlvinSD]

I had EBRT (IMRT) to my prostate / seminal vesicles, pelvic lymph nodes and lesion on my right hip. I never had any bone pain at all. (Lesion was just under 1 cm in diameter.). Super easy…they were able to hit everything with 28 treatments. Never any issues with the hip at all.

[AlvinSD in reply to tarzantass]

Stanford recently published a study where they showed the risk is only slightly higher. (Link to full article in JAMA Open included in this summary.)
