Slightly lower PSA than mine over ten years ago but same Gleason score. You should appreciate that your husband has a chronic incurable condition, as present medical knowledge suggests. You will probably find that zoladex if similar will be offered, possibly radiation therapy and hopefully chemotherapy too at an early date. You will need to prepare for the possible side effects of these treatments, which will have a marked effect on your relationship. I hope the bone scan is clear but with those numbers, it is likely that the PCa has escaped the prostate capsule. Spread to elsewhere in the body is possible at some future date, if it hasn't occurred already. Take assurance from the fact of my and others' survival with similar numbers, that your husband does not have a death sentence and will be able to live a long and fulfilling life despite the PCa.
Your questions should be designed to understand the treatment plan. I doubt if there will be options available, for example involving surgery, for this would probably be ineffective. Take notes, reflect on what you've been told and ask the oncologist or the oncology nurse anything you are unsure about before you leave the hospital. If you are still unsure, ask us on here.
