Almost my story exactly. Sorry to hear it. We can all take different lessons from our own outcomes, but this is one reason I encourage people (at least people at risk) to get their CA19-9 tested while they're healthy. They'll know their own normal so they can recognize a deviation.

Personally, I have become more suspicious of Total Neoadjuvant Therapy before Whipple and none after if patient is NED, and almost absolutely opposed to "wait and see" for anything.

I do wish you the best. I'm now 15 months out from my recurrence being suspected on MRI, and 12 months into chemo on Gem+Cis+Abraxane and doing pretty well, all things considered, but believe my team and I missed several chances for a much better outcome.
