What causes CEA levels to decrease after chemotherapy?
These results may show:
- Your levels of CEA started high and remained high. This may mean your cancer is not responding to treatment.
- Your levels of CEA started high but then decreased. This may mean your treatment is working.
- Your CEA levels decreased, but then later increased. This may mean your cancer has come back after you've been treated.
What are the causes of Elevated CEA?
- Cancer: It is a tumor marker and raises in the presence of a malignant tumor. ...
- In inflammatory bowel diseases (ulcerative colitis, diverticulitis, Crohn's, etc.).
- Liver disease ( cirrhosis, hepatitis, etc.).
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. It may also suggest that the cancer has metastasized, or spread, to other parts of your body.
How do I lower my CEA levels?
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.
Can CEA go down?
CEA decreases as you get older, but some conditions, including certain types of cancer, can increase your blood CEA levels. CEA is sometimes called a tumor marker or tumor antigen.
How fast does CEA decrease?
conducted a study of 136 mCRC patients where they tested patient CEA levels every 4 weeks and defined CEA responders as mCRC patients with a greater than 50% drop in CEA after more than 4 weeks. That study demonstrated the usefulness of CEA monitoring in determining the response to chemotherapy.
Can CEA levels increase with chemotherapy treatment?
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.
Why is my CEA going up?
A high level of CEA can be a sign of certain types of cancers. These include cancers of the colon and rectum, prostate, ovary, lung, thyroid, or liver. High CEA levels may also be a sign of some noncancerous conditions, such as cirrhosis, noncancerous breast disease, and emphysema.
Why does CEA increase after chemo?
The chemotherapy probably causes liver parenchymal changes and may cause transient increase of CEA with the same mechanism in the adjuvant settings.
What does a CEA level of 8 mean?
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.
What does a CEA level of 7 mean?
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 does a CEA level of 5 mean?
A normal result is less than 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.
How long does it take for CEA to return to normal?
Serum CEA has a half-life of 3–5 days, and serum CEA levels have been reported to decrease to the normal range from 2 weeks to 1 month after curative resection [5, 10, 11, 12, 13].
How fast does CEA increase?
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.
Is CEA level 4 high?
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.
How do oncologists use the CEA level?
Historically the main role for CEA has been in post colorectal cancer treatment surveillance along with clinical evaluation and CT/PET scans. Rising CEA levels may indicate a cancer recurrence sooner than PET/CT detection however this doesn't necessarily translate into improved survival. Moreover a high CEA level may occur falsely leading to significant anxiety and unnecessary tests to look for a recurrence that doesn't exist.
What causes CEA blood levels to increase?
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 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.
What is the Carcinoembryonic antigen (CEA)?
CEA is an antigen (small protein) that is found on the surface of colon, rectal, gastric and other types of cancer cells and high levels of CEA can be detected in the blood of some patients with cancer and the developing fetus. 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. The CEA test most often used for post colon cancer treatment surveillance and is likely to be replaced with ctDNA over time.
Can CEA levels increase with chemotherapy treatment?
Yes, CEA "flares" during chemotherapy don't mean the cancer is progressing. Cancer patients whose CEA blood tests rise at the beginning of chemotherapy and then fall (CEA flare) do better than patients with a consistently rising CEA.
What Have the studies shown?
Below are some of the key studies that helped define the role of CEA. It is the opinion of the Cancer Connect Editorial team that Tumor Informed ctDNA analyses should replace CEA as the best biomarker for evaluating recurrence risk because it is both more sensitive and more specific than CEA. Learn more here...
What antigen is associated with survival?
According to an article recently published in the Journal of Clinical Gastroenterology, levels of the carcinoembryonic antigen (CEA) and albumin (ALB) are associated with survival among patients with early colorectal cancer.
How long does CEA stay elevated after cancer treatment?
As cancer cells die, CEA is released into the bloodstream and levels can remain elevated for a few weeks after treatment, even if a tumor is responding well. For example, CEA results may be very high during and after chemotherapy.
What is CEA in medical?
on November 01, 2019. Carcinoembryonic antigen (CEA) is a tumor marker in the blood or other bodily fluids that can be used to monitor certain cancers such as colorectal cancer.
What is CEA test?
Purpose of the Test. CEA is one type of tumor marker used to monitor cancer. Tumor markers are substances that are either made by cancer or made by the body in response to cancer. Carcinoembryonic antigen (CEA) is a protein that is made by normal cells (and by the fetus during pregnancy), but is often produced in much larger amounts by cancerous ...
Why do we need a CEA test?
CEA is often ordered as a baseline test at the beginning of cancer treatment for this reason. To monitor for recurrence of cancer: If CEA levels were normal and are increasing, it may mean that a tumor has recurred. A major use of the test is to detect relapse after curative treatment for colon cancer.
Why do we draw CEA?
Some of these include: To monitor cancer treatment: If CEA levels are decreasing it usually means a tumor is responding to treatment, whereas if levels are increasing, it may mean the tumor is progressing.
What is the antigen for cancer?
Cancer antigen 19.9 (CA 19.9) may be used to monitor colorectal cancer, pancreatic cancer, liver cancer, and more. Cancer antigen 27.29 ( CA 27.29) may be used to monitor for breast cancer recurrence or progression and in stomach cancer, colon cancer, lung cancer, and more. Prostate-specific antigen (PSA) is used only to monitor (and screen for) ...
Where is CEA found?
CEA may be found in blood, urine, stool and other body fluids, as well as in the tumor itself.
What does CEA mean in cancer?
Your doctor can order a CEA test if your symptoms suggest you might have cancer. A CEA test can help your doctor find out if a cancer treatment is working. These treatments may have included surgery, chemotherapy, radiation, or a combination of all three. Your doctor might also use the CEA test to help determine if a cancer has come back, ...
Why do doctors use CEA?
Your doctor might also use the CEA test to help determine if a cancer has come back, or recurred, after finishing treatment. A CEA test is most useful after a diagnosis of a type of cancer that’s known to produce CEA. Not all cancers produce CEA. Increased levels of CEA may be found in the following cancers:
What is a CEA test?
What is a carcinoembryonic antigen test (CEA)? A carcinoembryonic antigen (CEA) test is a blood test used to help diagnose and manage certain types of cancers. The CEA test is used especially for cancers of the large intestine and rectum.
How long does it take for CEA to return to normal?
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.
What does it mean when your CEA is elevated?
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.
What does it mean when you have a high amount of CEA?
The CEA test measures the amount of CEA in the blood. A high amount of CEA in your body after a cancer treatment or surgery suggests the cancer is not gone. It may also mean that the cancer has spread to other parts of your body.
How to get blood out of your arm?
A healthcare provider will wrap an elastic band around your upper arm to help make your vein fill up with blood. A needle is then inserted into your vein to collect blood into an attached vial or tube. The band is unwrapped from your arm. A laboratory will analyze your blood sample.
How often is CEA measured?
In a follow-up of 311 patients with potentially curative resections of colorectal cancer, CEA was measured every 3 months for 2 years, then every 6 months for 3 years. [20] The sensitivity of CEA in detecting recurrence was 58%, with a median lead time of 6 months. The sensitivity was the highest for the hepatic metastases group (80%). The specificity, positive predictive value, and negative predictive value were 93%, 79%, and 83%, respectively. [20]
How much does CEA cost?
Limited data are available regarding the cost-effectiveness of CEA in detecting potentially curable recurrences. In the follow-up of patients receiving adjuvant therapy on a large randomized study of 1,356 patients, 2.2% of resectable recurrences were attributed to CEA screening. [28] The cost of CEA monitoring per detected resectable recurrence was $5,696, comparing favorably to colonoscopies and chest x-rays. [28] A recent study suggests a cost of $25,289 for each surviving patient after surgery for CEA detected recurrence. [45] Others have estimated that CEA costs are $500,000 per patient cured secondary to CEA screening, while some have suggested a range of $22,963 to $4,888,208 per quality-adjusted life-year saved. [46,47] Most estimates would be considered cost-effective when taking into consideration the current costs of treating metastatic colorectal cancer.
How long does it take for CEA to normalize after resection?
[17,18] This time frame of a few weeks to several months is consistent with an estimated CEA half-life of 3 to 13 days; longer half-lives are associated with higher preoperative CEA levels. [19]
What is the sensitivity of a CEA test?
[16] The sensitivity was 36% with a specificity of 87% for a CEA > 2.5 ng/mL in patients with stage I and II disease . [16] The sensitivity for stage III and IV disease at similar CEA levels was 74% and 83%, respectively. [16] The sensitivity decreased while the specificity increased for higher CEA cutpoints (5 ng and 10 ng). [16] The poor reliability of this test in early colorectal cancer and the imperfect specificity in the normal population makes this test unsuitable for primary colorectal cancer screening.
Why is CEA monitoring important?
CEA monitoring is helpful in detecting early recurrences in patients with resected colorectal cancer. Early detection of disease recurrence will enhance the chances of curative intent resection, resulting in a positive impact in a select patient population. The percentage of patients rendered curable secondary to CEA monitoring is likely less than 5% based on the reviewed literature. Thus, a definite impact on overall survival is unlikely to be detected unless a large randomized study addressing this issue is conducted.
Is CEA rise false positive?
Given the possibility of false-positivit y of CEA levels during the surveillance of patients with resected colorectal primary or resected metastatic disease, it is prudent to confirm an ongoing rise in CEA prior to the initiation of an extensive disease recurrence work-up. The degree in CEA rise is important in estimating the likelihood of false-positivity: Elevations of more than 15 ng/mL are unlikely to reflect anything but disease recurrence. [22]
Does bolus fluorouracil increase CEA?
Figure 1 illustrates a surge in CEA during adjuvant bolus fluorouracil (5-FU) therapy in a patient with a resected rectal cancer. The surge in this case lasted for several weeks and resolved spontaneously; the patient remains free of disease more than 1 year later. In the follow-up of 1,017 patients with resected colon cancer, Moertel et al described a 16% false-positive rate of CEA elevation when a cutoff of 5 ng/mL was used and a 4% false-positive rate when 10 ng/mL was used. [22] This was attributed to 5-FU and levamisole in the majority of cases. [22] These findings are consistent with preclinical data demonstrating an increased expression of CEA in response to chemotherapy exposure when agents such as 5-FU and platinum drugs are used. [70,71]
What does it mean when your CEA levels drop?
Test results that drop during treatment indicate therapy helped , and levels that remain high show treatment probably hasn’t curbed the cancer. If your CEA levels drop during treatment, but rise afterward, it may signal a recurrence.
What does a low CEA level mean?
Before undergoing cancer treatment, you may have your CEA levels tested. Typically, a low level indicates a small tumor that hasn’t spread elsewhere in the body. A high level may correspond to a larger tumor or cancer that has spread—or metastasized —to one or more locations away from the original site.
What is CEA?
While in the uterus, an unborn baby produces CEA, but healthy adults produce little or none of this protein. Smokers may have elevated levels of carcinoembryonic antigen, as well as people with the following noncancerous conditions:
What is CEA in blood work?
CEA is one of several substances called tumor markers that cancer cells release into the bloodstream. Others tests for cancer include: CA-125, an indicator of cancer of the ovaries, fallopian tubes or peritoneum (a layer of tissue enclosing your abdominal organs) PSA, or prostate-specific antigen.
Why do doctors not use CEA?
Because many types of cancer and several noncancerous conditions may cause high CEA levels, doctors don’t use CEA tests to diagnose a specific form of cancer or determine whether you have cancer. Rather, they’re used to monitor progress of certain treatments.
Where is the blood sample taken for CEA?
Most commonly, CEA tests involve taking a blood sample, a simple procedure where blood is withdrawn from one of your veins via a needle into a syringe or test tube. Less often, fluid may be collected from other parts of your body, depending upon the type of cancer and where a tumor may be located. Fluid may be extracted from along the peritoneum, the pleural space surrounding your lungs, or next to your spinal cord.
What are the non-cancer conditions that smokers have?
Smokers may have elevated levels, as well as people with the following noncancerous conditions: Emphysema. Cirrhosis. Benign breast disease. Inflammation of the gallbladder ( cholecystitis) Inflammation of the pancreas (pancreatitis) Peptic ulcer. Ulcerative colitis. Rectal polyps.

The Test
- The CEA test may be done in the hospital or in a clinic. The test is often run on a blood sample, but may also be run on fluid obtained from the central nervous system (via a lumbar puncture or spinal tap), from the pleural cavity (via thoracentesis), or from the peritoneal cavity (via paracentesis). The description below refers to having the test done in the most common way: th…
Interpreting Results
- A single CEA test may give doctors some idea about what is happening in your body. The test should be repeated if it is abnormal to verify the result.
Summary
- A CEA test can be useful in monitoring cancer treatment, but it's important to note that it should not be used alone and is most helpful when looking at changes in CEA levels over time rather than as a single value. Since CEA levels can take some time to decrease during colon cancer treatment, a health care provider will consider the whole picture ...
A Word from Verywell
- CEA levels can help your health care providers monitor cancer treatment and predict prognosis. However, the prognosis of many cancers is changing with newer treatments and technology. Keep in mind that currently available statistics don't necessarily reflect those improvements.
