Based on a person's exam, lab tests, and description of symptoms, a doctor often orders an imaging test: Computed tomography (CT scan): A scanner takes multiple X-ray pictures, and a computer reconstructs them into detailed images of the inside of the abdomen. A CT scan helps doctors make a pancreatic cancer diagnosis.
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.
