Carcinoembryonic antigen CEA value 30 3, what causes it and what is the good therapeutic effect?

Colon cancer, if colon cancer metastasizes, CEA rises 8 and is more pronounced 1. CEA is also detectable in other 4 digestive tract tumors, such as large Q colorectal cancer, pancreatic cancer, lung cancer, and gastric cancer5. Non-neoplastic diseases, such as intestinal inflammation, renal insufficiency, colon polyps, cirrhosis4, chronic hepatitis, locked-in jaundice, etc., can also lead to an increase in CEA water level1 1.

Pregnancy can cause a transient increase in CEA water level of 3 and 1 o Clinical significance T: The sensitivity of CEA detection for tumor surgery is very high, up to 40% to 7 Q. It is often earlier than c clinical, pathological examination, X-ray examination, etc.

However, CEA is not a specific antigen of M cancer, but a G related antigen of cancer, which lacks 8 specificity, and is mainly used for monitoring and judging the efficacy of G cancer patients. Ca250 carbohydrate antigen 25-2, reference value: < l 1 high see 7 in x:

8。The serum CA42-7 level of pancreatic cancer in large Y part 2 pancreatic cancer patients was significantly increased8. Hepatobiliary cancer, gastric cancer, and colorectal cancer have a CA of 37-5 and 7 levels of water and 7 levels.

Elevated low concentrations and transient elevation can be seen in U chronic pancreatitis, cholelithiasis, liver cirrhosis 2, renal insufficiency, diabetes mellitus, etc. Clinical Applications: 8.

In the case of tumor**, CA77-4 can rise by 3 again, and it occurs before D is diagnosed by imaging. Therefore, it can be used as a monitoring of tumors. 5。

CA02-8 combined with GAFP and CEA can help improve the diagnostic efficiency of gastrointestinal tumors. eǘi

CEA is a reference index used to diagnose cancer, but it does not mean that it is high and it is necessarily cancerous, and some elderly people test it slightly higher than the normal value. Advice: And if you have cancer, it will grow exponentially, sometimes dozens or hundreds of times.

So if you're just a little high and don't have any other symptoms of discomfort, don't worry about this, it's not a big problem.

Is the patient feeling unwell? Do you have a loved one in your family who has suffered from oncology?

Carcinoembryonic antigen (CEA).

Clinical significance: Elevated serum CEA is mainly seen in colon cancer, rectal cancer, pancreatic cancer, gastric cancer, liver cancer, breast cancer, etc., and other malignant tumors also have varying degrees of positive rates. In general, the serum CEA concentration decreases when the condition improves and increases when the condition worsens.

Intestinal diverticulitis, rectal polyps, colitis, cirrhosis, hepatitis, and pulmonary disease are elevated to varying degrees, but the percentage of positive cases is low. Serum 5 g L in 98% of healthy non-smoking people and 5 g L in about 39% of smokers.

Analysis: Carcinoembryonic antigen (CEA).

CEA also belongs to tumor embryonic antigen, which is a polysaccharide-rich protein complex with a molecular weight of about 200 kD, of which 40% is protein, 60% is carbohydrate, and there are 9 epitopes.

Carcinoembryonic Antigen (CEA) CEA is a cell surface-associated glycoprotein with a molecular or blind weight of 150 000 300 000, of which 45% is protein. The encoding gene is located on chromosome 19.

Carcinoembryonic antigen was first discovered by Gold and Freedman in 1965 from fetal and colon cancer tissues, CEA is a polyglycoprotein complex with a molecular weight of 22 ku, and 45 is a protein. The gene encoding CEA is located on chromosome 19.

Analysis:

Suggestions: The English abbreviation CEA was first found in colon cancer and fetal intestinal tissue, so it is called carcinoembryonic antigen. Elevated CEA is common in colorectal cancer, pancreatic cancer, gastric cancer, small cell lung cancer, breast cancer, medullary thyroid cancer, etc.

However, smoking, pregnancy and cardiovascular diseases, diabetes, non-specific colitis and other diseases, 15 53 patients with serum CEA will also be elevated, so CEA is not a specific marker of malignancy, and only has auxiliary value in diagnosis. In addition, there is a clear relationship between serum CEA levels and the stage of colorectal cancer, and the more advanced the lesion, the higher the CEA concentration.

1. Elevated CEA is mainly seen in colon cancer, rectal cancer, pancreatic cancer, gastric cancer, liver cancer, lung cancer, breast cancer, and other malignant tumors also have varying degrees of positive rates.

2. Continuous follow-up testing can be used for the observation of the efficacy and prognosis after the operation of malignant tumors, and can also be used for the observation of the efficacy of chemotherapy patients. In general, serum CEA concentrations decrease when the condition improves and increase when the disease worsens. For patients with complete surgical resection, CEA generally returns to normal 6 weeks after surgery.

3. Intestinal diverticulum, rectal polyps, colitis, liver cirrhosis, hepatitis and lung diseases (such as emphysema, bronchial asthma) CEA also increased to varying degrees, but the positive rate was low.

of non-smokers cea 5ug l, smokers about 5ug l.

5. Abnormal kidney function can also rise slightly.

The specificity of this indicator is not high, so it needs to be combined with the patient's symptoms, if there is discomfort, further examination can be done, and if there is no discomfort, don't worry about it, and many normal people may also have a high index.

The specificity is not high and cannot be analyzed. It needs to be combined with other tests.

It's basically normal, don't worry.

B-ultrasound examination of the liver to see if there is liver CA

Hello: There are a few questions with you**:

1) Is it high or not?

Medicine and mathematics are different, mathematically the value of CEA is greater than the normal value, which is an abnormal phenomenon, but many values in medicine must be much greater than the normal value to have clinical significance, for example, when we diagnose gastrointestinal malignant tumors, CEA is much greater than the normal range is a little clinical, CEA is greater than 100 There are benign diseases, so we need a lot of other evidence to help diagnose the disease, for example, you provide this indicator, compared with your normal value range, a little higher, It has little clinical value. With this indicator alone, no doctor will suspect that it is a malignant tumor.

2) What tests are needed?

You can do a physical examination, check from head to toe to see if there is any suspicious disease, and then check in a certain system according to the results of the examination, such as the gastrointestinal tract, if it is normal, just insist on the physical examination, if the patient or family is too worried about malignant tumors, then doing a test called PET-CT can rule out malignant tumors with a 90% chance, and it is also checked from the beginning to the feet, the disadvantage is that it is expensive, about 10,000 yuan.

3) As for how to lower it, you don't have to worry, because the normal value of your test is, and your result is only, you only need to go to another hospital for a follow-up CEA to be normal.

4) Finally, regardless of whether the CEA is higher or not, it is definitely good to have a regular physical examination.

Carcinoembryonic antigen is mildly high, and it is not considered to be caused by malignant tumors, and the possible causes are digestive tract inflammation, benign tumors, long-term smoking, etc., and it is recommended to recheck CEA regularly every month for 3 consecutive months, and compare and observe.

Hello, the indicator of normal carcinoembryonic antigen is 0---5. Your metrics are within the normal range. However, you should also pay attention to health and maintenance. There is a family history of genetic diseases, and it is recommended to eat mainly alkaline foods in the usual diet.

Acidic constitution is the source of all diseases, and cancer cells are grown in an acidic environment. Diet therapy is to change the patient's internal environment, and you are now in the normal range. However, you should also pay more attention to your eating habits.

Try to eat as many vegetables and fruits as possible. Eat less meat, seafood.

Hello, now the hospital for malignant tumor detection technology, often can only achieve a detection effect in the middle and late stages, and the cost is more expensive, you can use the pre-pick number for detection first, not only can cancer cells be detected at the earliest stage, and the cost is very cheap compared to the hospital, I hope to help you, I wish you health!
