Back and leg pain with SbRT.

[SuzeinDE]

Following day 13 of a 26-day adaptive SbRT program, my partner has developed significant pain in his lower back and thighs. The radiation is targeting his pelvic bed, with particular focus on his prostate and the one lymph node that lit up on PSMA PET. Has anyone else experienced this? If so, was there anything that brought relief?

He is 69, Gleason 9. Started hormone therapy in June--two weeks on Casodex, one 30-day Eligard injection before switching to Orgovyx. PSA is down to .5 from 36. He has heart failure so MO is foregoing abiraterone/prednisone for now, since the PSA response has been good.

Thanks for any advice.

Hi SuzeinDE,

One area of caution in the PCa world is "correlation does not imply causation" .

I offer this as I just had SBRT of 50Gy over 10 days to the pelvic region with no side effects.

At 71 and a G9 this also wasn't my first SBRT rodeo.

So I'm in the investigate other reasons bucket here. If it's sciatic type pain (lower back, one sided butt pain radiating down the leg) one possibility is his body position during treatment or moving on/off the bed has jammed a spinal facet. May be worth a visit to a sports physio or myo.

Thank you for your advice. The pain is subsiding, so it's likely you're correct that it is unrelated to the SbRT.

Best of luck to you in your journey.
