PSA Update- seems to be rising...

Hubby got the results of his recent PSA today. As he and Uro expected, it was up (but only a tiny bit). Last one was undetectable, this one was 0.02. He has also started having some bone pain, though that may be from the Lupron shots, too. He is convinced that it is going to keep going up. Uro said he wants to give Lupron 2 more tries- in other words give hubby 2 more shots (he gets them every 120 days). So we are looking at 8 more months of waiting. Hubby is going to drive me crazy I think waiting that long. But it gives me time to start review the literature and stuff for options. I hoping Uro won't just suggest switching to another HDT drug.

I realized I never asked my question in my original post. If anyone has any suggestions for me to explore, please share. Some one already mentioned a new treatment being tried in Germany and a very few places here in the USA- Lu-177-antiPSMA. I've done a little reading on that and will do more. I've also (previously) looked at Provenge. I know Insurance will be difficult about anything not 'tried and true and approved', but we are blessed (and lucky) that money will not be a real problem and we could seek out new possibilities. I appreciate any suggestions for my research.

Please read the below links. Heidelberg and Munich Universities are experienced with treating advanced prostate cancer patients with radioactively labeled PSMA-617.This treatment is still experimental but can add years to the lives of advanced pc patients. I've been at the Heidelberg University hospital and I was impressed with their professionalism and expertise.
