The basic decoding of oncomarkers
The blood test for tumor markers isa survey that allows us to identify the content of specific proteins produced by malignant tumor cells in a biological fluid. Oncomarkers are specific molecules that are produced in the human body in the development of cancer or some other conditions. Therefore, medical specialists can determine the possible development of cancer on the increased content of such bodies in the patient's blood. About how to decipher the analyzes we will tell in this article.
Identification of antigens
Correct interpretation of the substance content to solve such problems:
carrying out differential diagnosis of tumor formations at any stage of the disease;
establishment of efficacy of prescribed therapy;
monitoring the deviations of the clinical picture;
detection of recurrence or appearance of metastases at an early stage.
The most common substances that are determined during the tests are the following:
CA 125 is an indicator of ovarian cancer. Normally its value is from 0 to 30 IU / ml.
AFP is a cancer marker of liver cancer. Its specialists are also called alpha-fetoprotein, and the norm of the substance is from 0 to 5 U / ml.
REA is an antigen that indicates the development of colon cancer. Limit, showing the norm of content, ranges from 0 to 5ng / ml.
PSI or PSA is an oncomarker that signals prostate cancer. Its norm varies from 0 to 4ng / ml.
If one of the above substances is identified inblood decoding can testify not only to the development of malignant tumors, but also about inflammatory processes, organ dysfunction, diseases, etc.
Onco-markers of CEA: norm, decoding, possible diseases
As this oncomarker actsglycoprotein - a substance produced by the cells of the digestive tract of the embryo and fetus. However, an increased concentration of this antigen in the blood indicates possible malignant neoplasms. In the blood of a healthy adult human CEA is practically absent, therefore its content almost always indicates the development of cancer of the lactic and pancreatic, ovarian, and gastrointestinal tract.
Since it is impossible to establish an accurate clinical picture according to a single indicator of CEA level, as a rule, specialists prescribe several more tests to determine the diagnosis of the patient.
Onkomarkery on gynecology: decoding and possible diseases
This substance is produced in the tissues of organsGastrointestinal tract, gall bladder, kidneys, ovaries, and bronchi. The deviation from the norm of the oncoprotein CA 125 is a sufficiently accurate indicator, showing the development of a malignant tumor.
In the presence of this CA 125 in the patient's blood determines such pathological processes:
cancer of the ovaries or uterus;
swelling of the stomach or intestines;
malignant tumors of the breast;
cancerous neoplasms of the lungs;
diagnosis of liver cancer;
neoplasms of the pancreas;
Thus, we considered the main typesonkomarkerov, their decoding and possible diseases. Remember that the key to successful recovery is timely diagnostics from a doctor who can establish the correct diagnosis and save your life in time.
