A 61-year-old male asked:

Pancreatic cancer: what are other acronyms for carbohydrate ag 19-9, besides ca19-9, in the attempt to diagnose and monitor this cancer?

Only 19.9: The CA referring to carbohydrate antigen will not be altered in some pancreatic lesions, and not be elevated in others. Being CA in origin designates this marker as one to be used for monitoring and not diagnsis since it is only elevated in 60% of pancreatic cancers, elevated in other GI neoplasms and also elevated in inflammation.
