life expectancy greater than 6 months
has Eastern Cooperative Oncology Group (ECOG) performance status 0, 1, or 2

Patients with a PSA doubling time of <6months at screening would be excluded
Patients meeting Phoenix criteria for biochemical failure (nadir + ≥2ng/mL increase in serum PSA) who wish additional conventional therapy
Any concurrent malignancy other than adequately treated basal or squamous cell skin cancer or superficial bladder cancer
Any psychiatric or other disorders such as dementia that would prohibit the patient from understanding or rendering informed consent or from fully complying with protocol treatment and follow-up
