Description of current status and seeking advice

At age 64 in 1999, with PSA of 3.5, a nodule was found by DRE on the prostate gland, which was biopsied positive for PC with gleason of 7 (3-4).  Underwent prostatectomy (perineal) in 2001, but post-op pathology showed positive margins and seminal vesticle involvement. Yet PSA remained undetectable for 3-1/2 years but started to rise slowly. Per correlation studies at John Hopkins, (related to age, time since prostatectomy, and doubling rate) PSA was followed for 15 months, but with PSA doubling in approximately 10 months, salvage radiation (EBRT)  for 37 sessions was elected, which completed on 10-20-06. PSA again became undetectable until 02-08 when it rose to 0.3. Casadex 50 MG oral(alone) was prescribed, but by 12-08 PSA had risen to 1.5.  Casadex was discontinued by the Urologist and some alternate form of intermittant harmone therapy was discussed, but unfortunately none was initiated. By 04-09, I became very ill, with much pain. My Internal Medicine doctor ran multiple tests, including PSA, MRI's, CT and bone scan,  and found that the PSA had ran rampant in that uncontrolled period, and was at 167, with major metastasis into the entire spinal area and had caused a spine fracture.. He referred me to a new Urologist, a Medical Oncologist, and a Radiation Oncologist.Aggressive treatment in the last 5.5 months has included: 4-month Lupron shots, combined with 750 MG/day of Flutamide; blood transfusion; Kyphoplasty surgery for spinal fracture repair, Zomato (calcium) infusions each 3 weeks, and Morphine, Hydrocodone, and Radiation to control bone pain. PSA has been sucessively reported at 167, 186, 197, 120, 44. and pain is managed well. Any comments / comparative experience information or recommendations will be greatly appreciated.    .
