    Hi Jj950,

    CA 19-9 numbers are just one piece of information among several that doctors use to make treatment decisions.  One of my doctors told me that he looked for a doubling or tripling of the number.  Complicating this topic is that sometimes the treatments themselves can temporarily raise the number.

    Doctors can’t base treatment solely on a tumor marker because the number does not say anything about where and how the cancer is evolving.  Usually the next step if a rising tumor marker looks concerning to the oncologist, is to order scans to take a look at what is going on.  When are your next scans planned?

    Regards, Mary


    Can anyone tell me if they’ve experienced rises in their CA-19 after Fulfirinox chemo?  Diagnosed 1.5 months ago with stage iv with CA-19 of 5,200 – after cycle ONE 6,500 after cycle TWO 9,584.  Oncologist said he doesn’t always rely on these numbers.  Too soon to tell anything and whether or not to switch treatment plans.  concerning………  Any input is appreciated.
