Hello everyone, thank you for all your help for a year. My dad went from a high of 3103 PSA to a nadir of 44. He unfortunately couldn't reach a <1 result but it had stabilized for a few months after his docetaxel + zytiga + prednisone. Unfortunately his new result is 67 PSA exactly a year since diagnosis.
His doctor had ordered a bone scan and bone scintigraphy before it increased because he still had pain on his right hip and we're meeting her on the 30.
What should we ask her and what would be some options to explore? He doesn't have BRCA mutation. All it says (might not be legible as it was in french) is variant "c.530C>G / p.(Pro177Arg) in exon 5 of the gene TP53( NM_000546.5)" if that means anything to you all
I've researched a bit but I don't know how to take a PSA increase like his considering his initial PSA diagnosis was so high.
It was also a very weird shift in PSA over the months. He started Docetaxel on February and his PSA had stayed around 99 for several months under chemo and then very slowly went down to 44 in August *after* his chemo.
Thank you for any tips and questions I could ask to his doctor. Maybe trials to consider? Thank you!
Edit: If that is any interest, he couldn't handle monthly injections of Degarelix (Firmagon) so he switched to Decaptetyl (Triptorelin) every 3 months and his PSA actually dropped further. Not sure if it's related though.
