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.

How accurate 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 %.

What level of CEA indicates cancer?

The CEA is measured in the blood and the normal range is <2.5 ng/ml in an adult non-smoker and <5.0 ng/ml in a smoker. The most common cancers that elevate CEA are in the colon and rectum but it can be elevated with gastric, ovarian and other cancers.

Can CEA be normal with cancer?

Many cancers don’t produce CEA. If your CEA results were normal, you may still have cancer. Also, high levels of CEA can be sign of a noncancerous health condition. In addition, people who smoke cigarettes often have higher than normal CEA levels.

What is a CEA blood test for cancer?

The carcinoembryonic antigen (CEA) test measures the level of CEA in the blood. CEA is a protein normally found in the tissue of a developing baby in the womb. The blood level of this protein disappears or becomes very low after birth. In adults, an abnormal level of CEA may be a sign 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.

What is a high CEA level for pancreatic cancer?

Carcinoembryonic antigen (CEA) is a high–molecular weight glycoprotein found normally in fetal tissues. The reference range is 2.5 mg/mL or less. CEA has commonly been used as a tumor marker in other gastrointestinal malignancies, but only 40-45% of patients with pancreatic carcinoma have elevated CEA levels.
