I have done 14 rounds of same chemo, then y90 and last month a pancreadectomy. My CA-19-9 got to normal range but after the Y90 it jumped up . It’s now trending down again. I know your fears as I am sitting on them as well, but 2 points could even be a different lab processing results. My experience so far says 2 points not a worry; but I would be excited for the next labs. I’m told it’s about the trend more than anything. Sounds like you are doing great-the F drugs are no nonsense!!
