Many posts proceed this one and I am now at a crossroad. Scans since 7/21 showed uptake in either/or illiac, acetabulum and the ischium. After 2/23 scan I had 35 gys radiation to acetabulum. PSA dropped then started rising, 9/23 scan showed SUV uptake 28.4 at ischium. PSA 4.2 Local radiologist is concerned that radiating ischium close to the acetabulum could cause bone damage. The guy who did the original (who I really trust) feels the radiated acetabulum is far enough above the ischium so no problem.
The other option is replace Zytiga/Prednisone with Xtandi which I resist since Z/P is controlling all the other lesions and Xtandi can be used later if neecessary.
OK, so its radiation or drug change. What do you guys think? I see MO Wednesday to make decision.
