Can alcohol affect CEA levels?
Since both KCs and hepatocytes are known to be significantly impacted by alcohol, it is hypothesized that alcohol-related effects to these liver cells will lead to altered CEA processing, including impaired asialo-CEA degradation, resulting in changes to the liver microenvironment and the metastatic potential of CRC ….
What can cause high CEA levels?
The most frequent cancer which causes an increased CEA is cancer of the colon and rectum. Benign conditions which can elevate CEA include smoking, infections, inflammatory bowel disease, pancreatitis, cirrhosis of the liver, and some benign tumors in the same organs in which an elevated CEA level indicates cancer.
Can CEA levels fluctuate?
Serum CEA levels fluctuate over time in healthy individuals, and the intraindividual variation has been reported to be about 30% .
What is normal CEA range?
Normal Results 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).
How accurate is CEA blood test?
Sensitivity of CEA ranged from 17.4 % to 100 %, specificity ranged from 66.1 % to 98.4 %, positive predictive value ranged from 45.8 % to 95.2% and negative predictive value ranged from 74.5 % to 100 %.
What can cause a false positive CEA?
Elevated serum CEA is not highly specific for colon cancer recurrence, while various other gastrointestinal disorders such as pancreatitis, peptic ulcer disease, biliary tract abnormalities (benign or malignant) and liver disorders may contribute to increased serum CEA and false-positive results .
How often should CEA test be done?
CEA test. This is a blood test that detects the levels of CEA protein. High levels of CEA may indicate that a cancer has spread to other parts of the body. CEA testing is recommended every three to six months for five years.
What does CEA mean in a blood test?
A carcinoembryonic antigen (CEA) test is used to check how well treatment is working in certain types of cancer, particularly colon cancer. Carcinoembryonic antigens are substances (usually proteins) that are produced by some types of cancer.
What is considered a high CEA level?
Levels of CEA higher than 20 ng/mL are considered very high. If you have CEA levels this high and you also have symptoms of cancer, it strongly suggests the cancer has not been removed successfully after treatment.
Does CEA increase with age?
Background. Carcinoembryonic antigen (CEA), a serological marker of malignant tumors, demonstrates a modest increase under nonmalignant conditions such as aging and smoking. Also, recent study results suggested that serum CEA levels may be related to insulin resistance or low-grade inflammation.
Is CEA a reliable tumor marker?
Doctors don’t use the CEA test to make a first-time diagnosis of cancer. This test isn’t an accurate way to screen for it because many other diseases can cause the levels of this protein to rise. And some people with cancer don’t have high CEA levels.
What is a high tumor marker?
Tumor markers are substances found in the blood. Tumor marker levels may be higher when there is cancer in the body. They are not very “specific,” meaning non-cancer health issues can also cause these levels to be higher. They must be used along with radiology tests and exams by your healthcare provider.
