If you had to name one or 2 monitoring blood tests for pancreatic cancer would you include carbohydrate antigen 19-9 even with its false positives?

Monitoring not Dx. There are number of chemicals associated with pancreatic cancer. None of these is good for making a diagnosis, but may be used to monitor the progress of disease. However even for that the role is limited due to other issues affecting levels of these markers, including CA 19-9. See this site for more info on this topic. http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3079322/
Homework. Name whatever you think your instructor wants. All tumor markers have false negatives and false positives. CA19-9 is the most useful marker in pancreatic cancer. You're not going to use it for screening. It's helpful if the original tumor produces it -- rising levels let you know it's back.

Pancreatic cancer: Oncologist says CA19-9 blood tests are showing false negative (<37)results. How does he know for sure there is cancer?

More information. Hi. To me, that looks like very good information (the tumor marker is undetectable). If he has information otherwise, he needs to explain it to you. Was your CA 19-9 elevated before surgery, chemo + radiation? If so, and it's negative now, based on the information available, I'd say that's exactly the result you'd like to see! Ask him to explain his position. Good luck! Read more...

Understanding labs. This isn't a "false negative" -- a great many pancreatic cancers simply don't make CA19-9. There may also be too little cancer left to make enough to be meaningful. This is just one of many examples of how limited tumor markers are. I trust the oncologist has his/her reasons for believing cancer is present. You'll need to ask. Best wishes. Read more...

63 year old Male all blood tests normal except Ca19-9=2314. CT scan=enlarged panc. US=no stones. Can it be Pancreatic cancer?

Abnormal ct scan. The elevated Tumor marker and CT scan suggest possibility. However further tissue diagnosis is needed. Good luck. Read more...
Very suspicious. Hi. Why did your doc measure a CA 19-9? Yes, the result looks very elevated and suspicious for pancreatic CA. However, I can't imagine a radiologist reading an abdominal CT as "enlarged" pancreas. No mass? I don't want to guess with something so potentially serious. Talk with the doc ordering the studies and get a sense for where you're headed. Good luck! Read more...
