Thank you so much for your reply, Tony. I'm so appreciative of anything you and others can share.
My dad was diagnosed 3 1/2 years ago and was a 7 on the Gleason at the time (don't recall the stage at the time). It's apparently very aggressive, as his PSA the year prior was 0, and upon diagnosis it was high (I think in the 50's??) and already had metastasized to the bones.
The only treatment he's ever had is Lupron (other than a try with Casodex but side effects precluded him from continuing). The Lupron kept his PSA <1 or so for about 2 1/2 years, but his last several (maybe 4-5) PSA's have been rising.
He is 69 years old. I hope this helps and thanks again for your feedback and support.
