CA 19-9.....geotina said:CA 19-1 marker
I have not heard of this. George has blood work for his CEA, could this be the same thing?

Serum carbohydrate antigen (CA) 19-9 is considered to be the most sensitive/specific marker for pancreatic cancer, although it has also been associated with biliary, hepatocellular, gastric, colonic and nongastrointestinal malignancies. For pancreatic adenocarcinoma, CA 19-9 is reported to have a sensitivity of 70 to 90%, specificity of about 90%, a positive predictive value of 69%, and a negative predictive value of 90%.
CA19-9 is not recommended for use as a screening test for pancreatic cancer.
The use of CA19-9 testing alone is not recommended for use in determining operability or the results of operability in pancreatic cancer.
CA19-9 determinations by themselves cannot provide definitive evidence of disease recurrence without seeking confirmation with imaging studies for clinical findings and/or biopsy.
Present data are insufficient to recommend the routine use of serum CA19-9 levels alone for monitoring response to treatment.
However, CA19-9 can be measured at the start of treatment for locally advanced metastatic disease and every one to three months during active treatment. If there is an elevation in serial CA19-9 determinations, this may be an indication of progressive disease and confirmation with other studies should be sought.0 -

Hey Steve
This test is an interesting one - I've had them done all the time, because at one time, my onc thought I had pancreatic cancer with my bloodwork, CT and PET all giving strong indications. It turned out to be my liver though.
I can't say this test proved anything for me anytime I did it, but we kept doing it and I tracked the numbers.
In the past, they used to be off the charts and for a long time was in the high 600's. I think the last time I got one it was around 158, which was a good number. Normal ranges are between 0-37.
But the numbers may not be a good indicator of cancer activity. They use it for the pancreas and in conjunction with the liver tests.
That's a significant drop in numbers, so that's great. If you do the tests, just keep an eyeball on them, but try not to read too much into them. After 5 years, if I had that type of cancer, I would have checked out or certainly been sicker.
Take care - Craig0 -

Thanks Craig, Trying to keep up with the dr,s and their jargon is almost a job in it's self. I do feel much better about things and my father is feeling better than he has is almost 6 months. We,ve been through so much we almost anticipate the next heart break. God bless you on your journey to health
