Although many men may present with similar stats at diagnosis, some even having similar treatment early on, their response can then differ greatly. There are a number of reasons for this, the various types of cancer, where it is and is going, the effectiveness and timeliness of treatment in individual cases being some of them. Then if the disease advances, different consultants may decide on various further treatment options or combinations at certain stages or feel treatment within a trial could be of benefit. This means that an individual's rough and rocky road may be very different from others. So it may be that there is nobody here at present or has seen your post, that closely matches the path you have taken and has very similar statistics. This is perhaps a reason for lack of replies.
Some forms of HT can quickly reduce PSA and it seems Prosrap is doing so. I hope that will help control your cancer for a very long time but again this is something that works better and longer for some.
