I had the Whipple procedure with Flory four Knox six years ago. And a recurrence two years ago of pancreatic cancer treated by stereotactic radiation. But no chemo. Last year my CA 19 nine marker started increasing and hit 1500 before we had evidence of the tumor in a CT scan.

My CA19-9 has been reduced from about 1500 to 159 over the past few months . I just completed proton therapy and Gemcitabine/Abraxene three weeks ago so the CA 19 nine may not be 100% accurate at this point. Looking for advice on how good I should feel that it has been reduced to 159. What are the chances that I need to do more chemotherapy or proton therapy to get it under 34? CT scan will be in a couple of weeks. Looking for insights and comments on what do you think? Thank you, and God bless.🙏🏼💜🌈
