What level of CEA indicates cancer?
The normal range for CEA is 0 to 2.5 nanograms per milliliter of blood (ng/mL). If CEA levels remain elevated during treatment, your treatment may not have been as successful as hoped. Anything greater than 10 ng/mL suggests extensive disease, and levels greater than 20 ng/mL suggest the cancer may be spreading.
What is the normal range for CEA?
The normal range is 0 to 2.5 ng/mL (0 to 2.5 µg/L). In smokers, slightly higher values may be considered normal (0 to 5 ng/mL, or 0 to 5 µg/L).
What is the normal range for CA 19-9?
The normal range of CA 19-9 is between 0 and 37 U/mL (units/milliliter), but people with pancreatic cancer often have higher levels. Not every pancreatic cancer will cause elevated levels of CA 19-9, and some non-cancerous conditions (like pancreatitis and jaundice) can cause high levels of CA 19-9.
What level of CA 19-9 indicates cancer?
If your CA 19-9 is above 37 U/mL, you may have cancer of the pancreas, liver, gallbladder, lung, colon, or stomach.
What is a high CEA level for Stage 4 colon cancer?
Conclusions Patients with stage IV colon and rectal cancer with a CEA level greater than or equal to 275 ng/mL and an ALB level less than 2.7g/dL had a significantly shorter survival time.
What does CA 19-9 test for?
A CA 19-9 blood test may be used to: Monitor pancreatic cancer and cancer treatment. CA 19-9 levels often go up as cancer spreads, and go down as tumors shrink. See if cancer has returned after treatment.
What does a high CA 19-9 mean?
High levels of CA 19-9 are often a sign of pancreatic cancer. But sometimes, high levels can indicate other types of cancer or certain noncancerous disorders, including cirrhosis and gallstones. Because high levels of CA 19-9 can mean different things, the test is not used by itself to screen for or diagnose cancer.
What is a good cancer marker number?
Normal range: < 2.5 ng/ml. Normal range may vary somewhat depending on the brand of assay used. Levels > 10 ng/ml suggest extensive disease and levels > 20 ng/ml suggest metastatic disease.
Is CEA elevated in pancreatic cancer?
Carcinoembryonic antigen (CEA) is one of the most widely used tumor markers and is increased in 30%–60% of patients with pancreatic cancer.
Is a CEA of 9 high?
A high CEA level was defined as a level exceeding 5 ng/ml and a high CA19-9 level was defined as a level exceeding 37 U/ml.
How accurate is CA19 9?
Similarly, van der Waaij et al [ 36] demonstrated amongst 450 patients across 12 studies that while cyst fluid CA 19-9 is less accurate than CEA, CA 19-9 < 37 U/mL distinguishes pseudocysts and serous cystic adenomas from other pancreatic cystic lesions with specificity (98.0%) and sensitivity (19.0%) [ 36 ].
What is a very high level of CA19 9?
The tumour marker CA19-9 is a sensitive marker for pancreatic, gastric and hepatobiliary malignancies. High CA 19-9 level indicates unresectable lesions and a poor prognosis. The objective of the study was to determine the significance and implications of elevated CA 19-9 levels in the serum. A one-year retrospective review of all patients who had CA19-9 measured in our Medical Centre was undertaken; 69 patients were found to have CA 19-9 level above the cut-off value (37 U/ml).
What causes elevated ca 19 9?
Some types of cancer cells send CA 19-9 into the blood, where it can be measured with this test. A high amount of CA 19-9 is most often caused by pancreatic cancer. But it can also be caused by other types of cancer. And it can be caused by infections in your liver, gallbladder, and pancreas.
What constitutes high CA19 9 test?
When there are moderately high levels of CA 19-9 discovered on the blood test, then this may indicate the possibility of a malignancy. Although 95% of pancreatic cancers will create this type of result, certain other cancers and diseases can also simulate the results. That’s why this one test alone cannot be used as a screening tool for cancer.
