We met with the oncologist at UCSF. My husband will be part of the PSMA MRI clinical study that evaluates a new scan being developed for prostate cancer. They will be doing gene sequencing on his primary cancer in the prostate as well as sequencing the lymph nodes. Since he has been diagnosed as stage IV he will be starting on Casodex and Lupron ( every 3 months). I'm wondering if this is standard treatment and if we should be asking for anything different?
