My CEA has been a very sensitive marker for me.
The last time I went from 0.8 to 1.3, it was the start of my recurrence.
I did 10 or so rounds of FOLFIRI + VECTIBIX and got my CEA down to 0.7 for 2 or 3 monthly tests in a row. My PET scan showed no active cancer.
When I discontinued Irinotecan, the CEA went to 1.2 for the next two tests.
It’s not increasing, I guess - a good thing. But after 3 tests of 0.7 and 2 of 1.2, I found myself wondering if maybe just taking the Irinotecan had an impact? (Not necessarily that it means cancer is active, just that the “baseline” could be different somehow?)
Have another CT coming up next week and likely a PET after that, so just curious how to think about my CEA.
