What do oncomarkers mean in the analysis of blood Ca 72 4? Decoding of indicators

Blood test

The cancer marker Ca 72 4 can be detected in the human body in a small volume. Its synthesis in significant quantities occurs in the tissue fibers of the fetus, including that produced by cells of tumor formations. But this condition can mean the development of other, non-oncological pathologies.

Oncoprotein type Ca 72 4

In medical circles, this marker is used as follows:

  1. For the purposes of diagnostic measures of gastric ulcers.
  2. To observe the dynamics of tumor development and possible metastases.
  3. To monitor the therapeutic measures of cancer and non-oncological pathological processes of a diverse genesis.
  4. To diagnose a malignant or benign tumor in the ovaries.

Ca 72 4 blood test: what does it mean?

Positive relationship of the cancer marker between the volume, dimensions and stage of development of pathology provides an excellent opportunity to monitor treatment and find even the most remote metastases.

With the help of Ca 72, you can constantly monitor therapeutic procedures for oncology of the stomach, gastrointestinal tract, pancreas and ovaries. But at the same time it is recommended to carry out diagnostics for such oncomarkers: Са 19 9 and Са 125. Although Ca 72 4 can safely act as an independent analysis in the definition of a malignant tumor of the ovaries, even if Ca 125 shows a negative response.

What are the uses of the cancer marker Ca 72 4

Simultaneously with the study of Ca 72 4, it is recommended to perform an analysis for alpha-fetoprotein, since individual gastric tumor cells may resemble the structure of liver tissue fibers.

What is special about using a marker?

Since this cancer marker is characterized by poor sensitivity at low frequencies, it is not worth using it as a screening. A significant number of unreliable positive responses causes the need to additionally be screened for other markers to confirm or reject the diagnosis. Literally two percent of the results showed a positive response even in benign tumors. But this is much less than in the study of REA, where this mark reaches ten percent.

Due to sensitivity in the course of relapse, the tumor is detected in 79 percent of cases, and if this study is supplemented with CEA, the percentage will increase to 87. Therefore, to obtain reliable information, it is not enough to be guided by the results of one study, several analyzes should be done in parallel to other oncomarkers.

If this indicator rose in the blood only once, it does not yet speak of the development of cancer. It is important to conduct several more studies in dynamics and to direct forces to identify markers: Sa 19 9; Ca 125 and REA.


Important! The diagnosis of the oncology of the stomach, ovaries and other organs of the human body is confirmed exclusively by histology.


Analysis of blood Ca 72 4: interpretation of the norm

It is very important to correctly analyze the tests and other laboratory tests, especially when it comes to oncological pathologies. If it concerns the marker Ca 724, then its indicators are considered in tandem with other oncomarkers. But in any case, under normal conditions, the cancer antigen should be no more than, U / ml.

Indicators of the marker do not depend on the age and sex of the patient. This study is provided by the method of immunochleoluminescence analysis. Thus it is necessary to take a biomaterial from a vein on an empty stomach. Do not smoke for an hour before the procedure. This can affect the results. That's all recommendations, there are no other requirements.

The analysis of blood Ca 72 4: its norm and decoding

Once again I would like to draw your attention to the fact that a one-time positive result is not yet a cancer indicator. The specificity of the study is that the tests should be done periodically to observe the dynamics of tumor development.


Important! Cancer antigen can show normative value even at an early stage. This means that such a procedure is not suitable for screening.


An increase in antigen indicates:

  1. There is a malignant tumor of the stomach, ovaries, breast, intestines, lungs or pancreas.
  2. There is a tumor of benign or other pathology:
  • hepatitis in acute or chronic form;
  • ovarian cyst;
  • rheumatism;
  • gynecological pathologies in women;
  • diseases of mammary glands.

Even the concentration of cancer antigen can be determined by malignant or benign formation. If the index slightly exceeds the norm - most often the tumor is benign. When the characteristic is more significant than the standards, in 90 percent of cases - tumor formation is malignant.


Important! If after the treatment therapy the volume of the cancer antigen does not decrease, this indicates the dynamics of recovery in the minimum volume. It is necessary to choose another course of treatment to achieve a positive result and not to aggravate the patient's condition.


If oncomarkers in the blood are detected in a smaller amount, this means that:

  • the course of treatment is chosen correctly and the dynamics of therapy brings a positive result;
  • there is no tumor formation at all;
  • cancer is at an early stage of development.

If you have any problems with your health, it's important to consult a doctor right away. Do not self-medicate, diagnose yourself. Only a specialist will be able to understand what is happening, after a series of studies and analyzes. Be attentive to your health!
