Sorry for the late reply, but I always like to help another person if I can.

My mom had late recurrence to the ovary, jutting into the bladder. She was just shy of 3 years in remission when it was discovered. Definitely a blow, but all hope is not lost. They gave her targeted radiation, which obliterated the cancer with only residual cancer remaining. This was followed by a cleanup surgery. Her last CT did show some heightened areas of concern in the surgical bed, but they're not convinced this is cancer, although being in the surgical bed, chances are high. They started her on oral chemo that has her CA-19-9 trending downward and last Signatera test was negative.

It goes without saying, but hopefully your mom is at a top cancer center familiar with latest clinical trials and protocol for PC.

It's worth trying everything your mom is up for. My mom's oncologist said they may get to a point where they can treat this like a chronic disease. I don't know if we'll ever find a "cure" for cancer, but with targeted therapies, I believe it will be possible for people to live with cancer.

Good luck, and please keep us posted. There is every reason to hope! Advances are happening every day. My mom is 5.5 years post diagnosis. She was originally staged at 2b. She had the whipple, chemo, radiation, and is currently on oral clinical trial to keep cancer at bay. She goes in for a CT next month where we will find out if it's working, but blood tests indicate positive results.
