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 a significant rise in CEA?

Two distinct patterns of CEA rise were observed: a ‘fast’ rise in which serum concentrations reached 100 microgram/l within 6 months of the first elevation and a ‘slow’ rise in which concentrations remained less than 75 microgram/l for at least 12 months.

What does a CEA level of 300 mean?

A CEA level of 300 is above the normal reference range, but I’m afraid I can’t put this into context. This would probably depend on whether the level was going up or down, but it may not shed any additional light on what is already known about someone’s situation.

What is a good CEA value?

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 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.

Can CEA detect metastasis?

Conclusions: Currently, the most useful application of CEA is in the detection of liver metastasis from colorectal cancers. Because of the relative success of surgery in resecting hepatic metastases, serial determinations of the marker are recommended for detecting cancer spread to the liver.

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 high is CEA in colon cancer?

A CEA value of greater than 8 ng/ml was highly suggestive of residual disease or recurrence, even when no clinical evidence was present. Approximately 90% of the patients dying from colorectal cancer showed an increase in CEA to greater than 8 ng/ml during the course of the disease.

Does CEA go up during chemo?

An initial rise of CEA during chemotherapy in colorectal cancer patients may therefore not always indicate progression of disease but may be a transient CEA surge in patients responding to chemotherapy.

Is a CEA level of 5.1 high?

What can falsely elevated CEA?

Diabetes, smoking, chronic obstructive pulmonary disease, and colonic polyps were considered as causes of false elevation. The false-positive rates of CEA according to level were as follows: 5.1–10.0 ng/mL, 99.5%; 10.1–15.0 ng/mL, 87.2%; 15.1–20.0 ng/mL, 100.0%; >20.0 ng/mL, 33.3%.

How can CEA be reduced?

Thus, we suggest that exercise for 2-3 days per week decreases the expression of CEA and improves body condition, without loading fatigue or stress, which may contribute to preventing cancer in the elderly women.

What does a CEA level of 5.9 mean?

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. Other reasons can cause levels higher than 3 ng/mL.

How long does it take for CEA to go down?

Most healthy people have levels below this amount. CEA levels will generally return to normal between one and four months after the cancer has been successfully removed.
