Nothing left to offer in the way of therapy?

What did you do when you yourself or a loved one was informed by the oncologist that s/he had nothing else to offer.

Having had a repeat CT/PET scan today (1 June 2023) to check on the status of my adenocarcinoma of the pancreas (finally diagnosed in late September 2022), the preliminary results have been reported as, what I can only describe as, at best ambiguous. Some findings today were slightly improved, none remarkably improved, and some slightly worse.
I have a medical background, including training in radiology and other imaging techniques. Although it was many years ago now, I believe I retain enough knowledge to understand what I've read.
I am trying to hold my Anticipatory Anxiety at bay until after my scheduled appointment tomorrow with my very busy oncologist. I hope he will finally have enough time after the last couple of rushed appointments to have a serious discussion about what, if any, my options might be at this point.
As further background, as best as I can now recall
I had one serious GI infection as a young adult (lost 10 lbs in a week thanks to both vomiting and diarrhea; even had the worry about dying soon that is supposed to happen many times after a life-threatening illness). This may have been about 1973.
In 1984, I had Guillain-Barré syndrome following becoming involved in a dysfunctional relationship (hospitalized for one month, back to work full time after 3 months; walking normally some 11 months later; final lingering symptoms of numbness in my toes finally resolved in 2001 after starting regular deep tissue massage)
A vague recollection of being told by a GI doc not to be impatient that my gut needed time to heal; I don't remember the precipitating circumstances, but believe it was probably GI bleeding serious enough to land me in the hospital, after which I was sent home with a steroid prescription (probably prednisone) which was tapered from a high of 65 over some interval before stopping) This episode is long enough ago now that it was not moved over from paper charts to Epic when my hospital started with that system, and I am uncertain about when this happened other than it was after 1984; I believe it was stress induced.
Starting about January 2022, I had an increase in the foods I could no longer tolerate without developing diarrhea. At the time I believed it was a flare in my I B S (which had been under good control as long as I avoided known trigger foods).
Now, I wonder if it was, instead, the first sign that my pancreas was starting to develop exocrine insufficiency.
I will refrain from going further astray by speculating about the possible role of the mRNA Covid vaccine in this sorry story, since it may distract from your answers about how you handled being given what can seem like a death sentence.
