So I’m very frustrated. My brother, stage 4, Gleason 9, PSA 56 diagnosed October 2018 Is getting confusing information from his doctor. He’s on Lupron has had chemo (dox) Zytiga, Provenge and Radiation to prostate. Zytiga worked for eight months .02 then started rising. We have asked repeatedly for gene sequencing. She keeps putting us off. We asked for Provenge but she said there was better things out there but never said what. I feel like we tell her what’s going on and she does not guide us at all. When she was out on a medical leave we saw another doctor and he immediately put my brother on Provenge. As soon as he stoped Zytiga his PSA dropped. When his doctor came back she put him back on Zytiga which of course failed again. More time wasted. Now she wants to start him on Xtandi. I believe it is the same class of drugs and probably won’t work either. We continue to ask for gene sequencing. She now wants to use an old biopsy from two years ago. From what I understand from the doctor standing in for her was that genes can mutate and there are two germ lines. I believe he said we would need a current biopsy. We can’t get it from the prostate because it’s been radiated. I wish I knew that before it was radiated. I don’t want to lose any more precious time. A scan just a week ago showed two new Mets one on the pelvis and one on the hip. Should we go with an old biopsy and start Xtandi like she wants to? There are so many intelligent people on here I value your input. I cannot thank you enough for the time you spend and your dedication to this forum and helping others
