Cancer Pei antigen(CEA)

Cancer Pei antigen(CEA)
【Make reference to a value 】
The Mao allied immunity adsorbs experiment:<5 μ gsL
The single gram of Long antibody is mutually solid the Mao unite a method:
<3 μ gsthe L is normal
3~5 μ gsthe L is suspicious
>5 μ gsL masculine gender
【Clinical meaning 】
The cancer Pei antigen is mainly existed to keep, organization and baby's bowel of colon cancer glue inside the film, colon cancer, stomach cancer, lung cancer and bile duct cancer that index sign obviously go up.Also Be existed to tumor organizations, such as liver cancer, pancreas cancer, kidney cancer, mammary glands cancer, oesophagus cancer and ovary cancer...etc. in.The cell secretes output CEA into partial body fluid and blood, therefore serum and chest, stomach water in above-mentioned cancer can appear a CEA abnormality to increase Gao inside the digestive juice.Chest water CEA of lung cancer is usually higher than serum.
CEA as usual the reference value has a little bit difference because the method is different.Its content asexuality difference, but increase Gao to have a little bit ascension with the age.The smoker has a light degree to increase Gao.
When the earlier period didn't transfer, the original hair colon rectum cancer's CEA masculine gender leads to 45%~80% or so, have been already transfered of sufferer density and masculine gender of its CEA check a rate to all go up.The CEA measurement can be used as one of the basis of observation curative effect.
The cultural heritage reports the masculine gender rate of a pancreas and Dan way tumor to reach to 60%~70%, the stomach cancer, lung cancer masculine gender leads 50% or so.When hardenning sex liver tube was burning also it is thus clear that CEA goes up.
Other diseases such as:Benign tumor, burning disease and back the content of going sex disease(colon polyp, ulcerate sex colon burning, pancreatitis, alcohol the liver Be hard to change, movable sex liver is far-gone) parts of patients can also increase Gao, but it is worth away below and malignant disease, is more generally small than 20 μ gsL.Can do a dynamic state observation for some hard discriminating of case, its value gradually ascension or keep on high level then the positive possibility is smaller.
