What cancers are high in CEA? What cancers are high in CEA?, What cancers increase CEA?, Can CEA be high without cancer?, Is CEA a good indicator of cancer?, What is the CEA level for Stage 1 colon cancer?
Although CEA is predominantly associated with gastrointestinal tumors, literature shows its close correlation with breast, lung, ovarian, mucinous adenocarcinomas of the cervix and thyroid cancers.
Can CEA be high without cancer?
Since serum carcinoembryonic antigen (CEA) can be falsely elevated in non-malignant conditions such as chronic obstructive pulmonary disease, peptic ulcer disease, gastritis, and diabetes, it is generally considered nondiagnostic [1,2].
Is CEA a good indicator of cancer?
CEA doesn't necessarily tell you whether you have cancer and providers don't use it to screen for cancer. It instead should be used in people who've been previously diagnosed with certain types of cancer, most commonly colorectal cancer.
What is the CEA level for Stage 1 colon cancer?
Conclusions. Preoperative CEA levels at or above 2.35 ng/mL, found within the normal range, may be used to identify stage I and II colon cancer patients harbouring worse prognosis.
What CEA level indicates metastasis?
Moreover, in patients with tumor metastasis, serum CEA was significantly increased in patients with multiple metastases compared with patients with single metastasis. A cut-off of 7.17 ng/mL could optimally distinguish between single metastasis and multiple metastases.
Does high CEA mean metastasis?
CEA test results
As a general rule, if the patient has been diagnosed with cancer: A low CEA level indicates a small tumor that hasn't spread elsewhere in the body. A high CEA level may correspond to a larger tumor and/or cancer that has spread—or metastasized—to one or more locations away from the original site.
What CEA level is a Stage 4 cancer?
For example, those with stage 3 colon cancer have CEA at 5 ng/mL or less, while patients with stage 4 colon cancer tested more than 5 ng/mL. CEA levels that are extremely elevated, such as going as high as 20 ng/mL, could suggest that cancer has started to spread to other tissues – a process called metastasis.
Is CEA only for colon 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.
What can falsely elevate 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 [2].
When should I be worried about CEA?
A normal result is typically less than 2.5 nanograms per milliliter. Results might vary between labs. 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.
Does normal CEA mean no cancer?
Ask your healthcare provider what your test results mean for you. CEA is measured in nanograms per milliliter (ng/mL). Normal results are 2.5 ng/mL or lower in nonsmokers. But having a normal CEA level doesn't rule out cancer.
Is 3.5 CEA level high?
A normal level of CEA is less than or equal to 3 nanograms per milliliter (ng/mL). 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.
Can you live 10 years with stage 4 colon cancer?
Stage IV colon cancer has a relative 5-year survival rate of about 14%. This means that about 14% of people with stage IV colon cancer are likely to still be alive 5 years after they are diagnosed. But you're not a number. No one, including your doctor, can tell you exactly how long you'll live.
How accurate is a CEA blood test for colon cancer?
Conclusion. Results point toward a sensitivity of CEA ranging between 50 % and 80 %, and a specificity and negative predictive value above 80 %. Results on positive predictive value showed low reliability.
