Hi Dennis-
It sounds like you are working with a good oncologist.
You said, "MRI confirms small tumor in the Lymph Nodes, but no indication of spreading to other organs or bones." MRI isn't very good at detecting infected LNs - it only shows enlarged LNs that may or may not be metastatic. But the bigger question is what to do about
any you find. There are no data that show any survival improvement from zapping individual metastases, although it might drive PSA down for a while. Radiation of individual metastases is only standard of care for bone mets that might fracture or cause pain.
But it sounds like you might be a good candidate for a very promising clinical trial. They are looking for men who are castration-resistant but do not yet have any confirmed distant metastases. It uses a radioactive element, Lu-177, that is targeted to prostate cancer cells specifically. Here are the details:
/clinicaltrials.gov/ct2/show/NCT00859781At the bottom is a list of places that are recruiting patients for this trial. Feel free to contact them directly - they are usually thrilled to talk to patients.
