Your question: What is the cancer marker for stomach cancer?

What is a high CEA level for stomach cancer?

In patients with nonresectable cancers, the CEA value was 83.0 ± 235.5 ng/ml, the CEA positivity rate was 47.8%. Overall, of 252 patients with primary gastric cancer, 47(18.7%) were positive for CEA. In patients with cancer recurrence, the CEA value averaged 41.8 ± 101.8 ng/ml, the positivity rate was 63%.

Is CEA elevated in stomach cancer?

Results: The serum CEA and CA 125 levels were found to be significantly elevated in gastric cancer patients than in controls. The serum level of CEA had showed a significant elevation with the presence of distant metastasis.

Does a CEA blood test detect stomach cancer?

High CEA levels may also be a sign of some noncancerous conditions, such as cirrhosis, noncancerous breast disease, and emphysema. A CEA test can’t tell you what kind of cancer you have, or even whether you have cancer. So the test is not used for cancer screening or diagnosis.

Which tumor marker is elevated in most cancers?

Guide to Tumor Markers Used in Cancer

Tumor Marker Cancers Associated With Elevated Results
CA 27.29 Cancer Antigen 27.29 or Carbohydrate Antigen 27.29 Breast** (best used to detect recurrence or metastasis). Colon, gastric, liver, lung, pancreatic, ovarian, prostate cancers
Calcitonin Medullary thyroid cancer**
THIS MEANING:  Can a CT scan alone detect cancer?

What is considered a high cancer marker?

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.

What level of CEA indicates cancer?

Elevated levels of CEA occur when the CEA is higher than 3 ng/mL. These levels are considered abnormal. People with many types of cancers can have levels that are higher than 3 ng/mL. If you have values that are that high, it doesn’t mean you have cancer.

Why is CEA high without cancer?

Higher than normal CEA level alone cannot diagnose a new cancer. Further testing is needed. An increased CEA level may also be due to: Liver and gallbladder problems, such as scarring of the liver ( cirrhosis ), or gallbladder inflammation ( cholecystitis )

What is a normal CEA tumor marker?

Tumor marker, CEA: Carcinoembryonic antigen (CEA) is a protein found in many types of cells but associated with tumors and the developing fetus. CEA is tested in blood. The normal range is <2.5 ng/ml in an adult non-smoker and <5.0 ng/ml in a smoker.

How reliable is a 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 %.

Can CEA be elevated without cancer?

Can CEA be high without having cancer? Yes, elevations in CEA and CA 19-9 levels may occur in patients without cancer. In fact studies suggest that falsely elevated levels may occur in up to 50% of colon cancer patients post treatment leading to unnecessary anxiety and testing.

THIS MEANING:  What is the survival rate of lung cancer in Canada?

Does high CEA always mean cancer?

A higher-than-normal CEA level that increases over time might signal that your cancer has grown or has come back after treatment. But high levels of CEA do not always mean you have cancer. These other conditions can also increase levels: Breast cysts.
