Dear Mags,
Welcome to a very supportive website. Please know that this group cares about each other and gives thest advice they can. I am also 57 and 4 months following a robot procedure done at Baylor in Houston. That operation is very minimally traumatic, and if they can carry through with it, recovery will be very fast and relatively painless.
Apparently, because they have offered you the robotic surgery, they felt that the problem was fairly locally contained--the routine is usually to do a bone scan and maybe a CAT scan, and if these don't show advancement, they go for the robot. Sometimes, they have to convert from a robotic to an open, but it would be unlikely with the information that you give, that they would just open and close. However, this is a disease in which something can usually be done over a long period of time.
If that unlikely thing happens, look at the websites for and into contacting the Baylor College of Medicine Dept. of Urology (Brian Miles, M.D.) or Radiology (Brian Butler, M.D.), to inquire about their gene therapy research protocol. It may be that this is a multicenter study and Tulane may be involved with it. Tulane has a very close relationship with Baylor because, while Tulane was getting things back together after Katrina, Baylor took over their medical students and made it a combined medical school for a while.
All the best for Monday, and please keep us posted.
