There is a tumor marker for some cancers of the colon; it is known as carcinoembryonic antigen, or CEA.Unfortunately, this protein may be made by other adenocarcinomas as well, or it may not be produced by a particular colon cancer.here is a tumor marker for some cancers of the colon; it is known as carcinoembryonic antigen, or CEA.
The best known of the blood markers for pancreatic cancer is CA19-9, a âcarbohydrate associated antigenâ also known as a sialylated Lewis (a) antigen.This marker is somewhat uneven in the diagnosis of pancreatic cancer, but can be quite elevated in those with pancreatic cancer.Approximately 10% of Caucasians lack the Lewis antigen, so in them the CA19-9 is not expressed.urrently, some oncologists appear to feel that the best use of the CA19-9 marker is as a guide to follow the disease and treatment process in a given individual patient. There are mutations in specific DNA genes that are found commonly in pancreatic cancer. Some of these well-known genes are k-ras, p53 and p16.
