HE4 epithelial ovarian cancer marker (human epididymal protein 4)

Many malignant tumors can be detected using a blood test for tumor markers — specific substances secreted by malignant cells or normal tissues in response to cancer. The human tumor epididymal protein, HE-4, is a tumor marker of ovarian and endometrial cancer. Let us see what it is and how to correctly interpret the results of the blood test for HE-4.

What is the analysis of non-4

HE-4 is a protein compound that is considered specific for the epithelial tissue of the reproductive organs, respiratory tract and pancreas, so it may normally be present in the blood of women and men. But its increased amount is most often found in epithelial cancer tumors of the ovaries and endometrium, because in them, under the influence of certain genes, this protein is synthesized in a large volume.

A feature of the HE-4 protein is that it begins to "roll off" at an early stage of cancer.

Numerous studies have shown that the test for HE-4 is positive in about 75% of women with oligosymptomatic preclinical stage ovarian or endometrial cancer. In addition, the test for HE-4 practically does not give false-positive results for benign tumors of the female reproductive organs, that is, it is highly specific.

For a more accurate diagnosis of malignant epithelial ovarian tumors, oncologists recommend simultaneously determining two tumor markers: HE-4 and CA-125 - this is the so-called testROMA(link).

Gynecologists and oncologists send their patients for the analysis of non-4 in the following cases:

  • If a woman wants to undergo a screening test to detect ovarian cancer in the early stages of development.
  • If neoplasms are found in the small pelvis of the patient - to differentiate the malignant and benign process.
  • If a woman is being treated for ovarian cancer - to monitor the effectiveness of therapy.
  • If the patient is diagnosed with a malignant ovarian tumor - to assess the prognosis, for the timely detection of recurrence of the neoplasm and metastasis.

How to take an analysis

To determine the level of non-4 in the body of a woman take venous blood. It is necessary to hand over it on an empty stomach (in the morning before going to the laboratory, you can only drink water). On the eve of the study it is recommended:

  • Completely exclude smoking and alcohol.
  • Do not take medicines (for women who are undergoing any treatment, this item must be coordinated with your doctor).
  • Limit physical activity.

Normal values ​​of the tumor marker HE-4

The concept of the norm in the case of the analysis of non-4 does not have a clear framework. The laboratory can only give reference values, that is, the average index characteristic of a healthy person of a certain age group. The magnitude of the reference values ​​largely depends on the equipment on which the research and test systems are carried out.

In different laboratories, the normal values ​​of the level of a tumor marker determined may differ slightly.

If we take the averaged numbers, then the content of the tumor marker NO-4 in the blood of women should be as follows:

  • up to 40 years - not more than 60 pmol / l,
  • in premenopause - no more than 70 pmol / l,
  • in postmenopause - no more than 140 pmol / l.

In addition, the correct interpretation of the results of any blood test is impossible without knowledge of other data about the patient (age, weight, disturbing pathological symptoms, the presence of comorbidities, the treatment being taken, the results of other tests, etc.). In this connection, only the attending physician, who knows all the historical and clinical information about the patient, can give a competent interpretation of the result of the test for HE-4.

Deciphering the result

A woman who has passed a blood test for HE-4 may receive two options for the results of the study:

  • the concentration of tumor marker in the blood is within the reference values ​​of the laboratory,
  • the content of non-4 in the blood is increased.

The first option can be considered the most favorable, since it fits into the normal range. However, the low level of HE-4 can not be regarded as absolute evidence of the absence of a woman with a malignant tumor, especially if there are any clinical symptoms. Such patients need to conduct other examinations, since for some types of tumors of the reproductive organs, the value of the indicator HE-4 remains normal.

The second option (elevated level of HE-4) indicates that a malignant process develops in the ovaries or endometrium of a woman. To confirm the diagnosis of such patients, additional studies are required - histological analysis of biopsy material, MRI, etc. In addition, although the tumor marker under consideration is considered to be highly specific for ovarian cancer, an increase in its concentration is also possible in malignant tumors of the mammary glands, lungs, bladder, and digestive organs.

High levels of HE-4 in the blood can be detected in women who do not have cancer, due to the progression of severe renal and hepatic diseases. Such pathologies include renal fibrosis, renal and hepatic failure.

If a woman has already been diagnosed with ovarian cancer and a study on HE-4 was administered to her as part of monitoring the effectiveness of treatment and monitoring the course of the disease, the doctor may interpret the increased level of the tumor marker in the patient’s blood as follows:

  • the tumor is aggressive, the prognosis is unfavorable,
  • treatment is ineffective,
  • there was a relapse of cancer
  • metastases developed.

There may be other explanations for the increase in the level of non-4 in the blood of women who have been treated for ovarian cancer. In addition, the results of previous blood tests for HE-4 are also relevant. For example, the indicator may be higher than normal, but significantly lower than a month ago. And this is a positive trend. In this regard, the result of the study must be shown to your doctor, leaving him the opportunity to draw conclusions and make adjustments to the treatment plan.

Marker description

The indicators of the majority of tumor markers are used in modern medicine for the diagnosis of cancer.

In most cases, they represent a specific protein structure, substance or antigen, their high content in the patient's sample under study may indicate the presence of a malignant process. However, this is not always the case.

For example, the marker of the cancer-embryonic protein (CEA), which is often used in examinations, may increase with a benign cell change.

In other words, oncomarkers are relative indicators for assessing the likelihood of cancer.

The final diagnosis can be made after a CT scan, MRI, biopsy, or histology taken from a tissue sample.

Note that accurate diagnosis of the disease is very important in order to carry out proper planning of the surgical procedure. Both elevated and normal results when donating blood for tumor markers will not give an accurate answer about the presence of oncology. In this case, specific proteins are often used to track the dynamics of antitumor treatment.

The rates of many tumor markers depend on the method and test system used in your chosen laboratory. Information about the range of values ​​of tumor markers will be contained in the results of the analysis, which will be given to the patient in the laboratory. Typically, the ranges of values ​​are indicated in the adjacent column, next to the patient's result.

With overestimated indicators, the graph is additionally highlighted with a special mark.

If you use the value of selected tumor markers as estimates of your own state of health, for accuracy, it is better to pass tests using the same methods and test systems.

Reference data of tumor markers can be obtained in the laboratory directly or on the official website.

Our review presents the regulatory results of some tumor markers, as well as test systems that are commonly used for evaluation. We pay attention once again that both normative and elevated indicators do not allow making accurate conclusions about the presence or absence of cancer.

Tumor markers to determine the type of tumors, and what it is better to clarify with examples. What indicators should be determined in each specific case, you need to ask the doctor.

Standard values: 0.90 - 6.67 u / ml (men and non-pregnant women).

The AFP tumor marker is used as a test value that measures the level of serum embryonic protein, which is produced during the embryonic period.

In adults and non-pregnant women, the value is constant and significantly less than in infants and pregnant women.

The growth of alphafetoprotein can be observed in malignant tumors and is observed in liver cancer. Also, its increase can occur in benign tumors.

HE-4 tumor marker is a special protein produced by the body as a defense mechanism in the presence of a tumor, the formation of which is malignant. This substance is contained in the blood of each person. In the event of an increase in its concentration, additional diagnostic measures are prescribed to patients to determine the cause of this disorder.

The concept of a tumor marker and its features

Cancer markers are a group of biological molecules. They have a different origin, but all clearly define very important indicators - the presence of them in large quantities in the blood indicates that a benign or malignant neoplasm develops in the body. These are specific indicators of the presence and progression of oncological disease in the human body.

Depending on the level of their content in the blood, oncological markers help to determine whether there is a malignant tumor, as well as its localization.

Diagnosis of blood is assigned to two main functions - to identify and confirm the presence of a tumor or to refute the diagnosis.

At the moment, a large number of markers are known. Their number exceeds 200 units. But laboratories determine only 15-20 of them, because they are informative. All the others can give the wrong result, since their level in the body changes in the case of other diseases, not only with the development of oncology.

There are different types of protein that talk about different types of oncological formations. They all have a specific name. Due to this, the doctor after the assessment will be able to determine the type of neoplasm, which organ is infected.

No marker, unfortunately, can determine the specificity of an organ with a 100% probability. This suggests that one type of marker is capable of talking about the oncology of multiple organs.

Despite this, thanks to oncologic markers, it is possible to determine a tentative list of affected organs and not to guess at what particular organ is ill. When the study on cancer markers shows an increased level of specificity, additional methods are used to assess the condition of the organs that are in doubt.

The procedure is most often prescribed for women in the event of complaints on their part. These manifestations include:

  • loss of appetite, normal weight,
  • the presence of unpleasant pain in the pelvic region,
  • there is a lack or irregularity of the menstrual cycle,
  • woman feels unwell.

When menopause is necessary to diagnose the course of the disease. Women who suffer from pathological changes in the development of the pelvic organs, women with hereditary predispositions are at the risk zone. This group may also include people who work in harmful enterprises.

Cancer markers as relative indicators of cancer risk

The results are prepared within two days after delivery.

Blood should be donated when pains appear in the lower abdomen, pelvis, in case of failures of the menstrual cycle, loss of appetite.

If the indicators are below normal - this is not critical, the reason for excitement is an increase in performance.

After receiving the results of the analysis on the tumor marker He4, decoding should be carried out by a specialist. To decipher the analysis, the doctor takes into account all the factors that could affect him - the menstrual cycle, the hormonal state, and others.

Decoding and rate of He4 tumor marker - indicators that help the doctor determine the type of further treatment. This analysis is a screening test; it must be tested several times to verify the results.

In the blood of all women is detected tumor marker He4, the rate of performance of which depends on the age of the woman.

  1. In young women during the childbearing period, the normal rate does not exceed 70 pmol / l.
  2. He4 tumor marker - the norm in women who have menopause, may increase to 140 pmol / l.

It is precisely because of the fact that the indicators for He4 tumor markers are changing, the decoding should be carried out by a highly qualified specialist, who will take into account all the indicators and features of the woman.

Attention! If the analysis for the HE4 tumor marker showed higher than normal results, this does not mean that there is a malignant neoplasm. In this case, the doctor prescribes additional examinations: x-ray, ultrasound or MRI.

When making a diagnosis, a doctor cannot take into account only a blood test - it is not a 100% indicator. Women whose He4 oncomarker rate exceeds the permissible values ​​are assigned a lot of additional tests and diagnostics. Only after a comprehensive examination, the doctor can accurately diagnose.

When deciphering the analysis in adults, low rates are not taken into account. To determine the presence of tumors are important only elevated rates.

Regulatory values ​​(for men):

  • up to 40 years: up to 1.4,
  • 40-50 years: up to 2.0,
  • 50-60 years: up to 3.1,
  • 60-70 years: up to 4.1,
  • over 70 years old: up to 4.4.

The antigen is used to assess the state of the prostate, increases in all types of lesions - inflammatory and benign, especially increases in the malignant cancer process.

Urine Microglobulin Beta 2

Regulatory values: 0 to 300 ng.

Microglobulin in urine Beta 2 in clinical practice is evaluated only when it is increased. In some cases, it can occur with tumor damage to the kidneys. Microglobulin Beta 2 tests are often done during treatment. Its increase is characteristic of some non-neoplastic diseases of the kidneys and in case of rejection of the renal implant.

Rates and deviations

The presence of this marker is detected in all females. Oncomarkers are not 4 decoding depends on the age category, which determines the normal content of the substance. During the period of childbearing age, the indicator should not exceed the value of 70. In the period of the onset of menopause, an increase in the value to 140 is observed.

Not 4 oncomarker transcript norm may vary. Decoding should be done by a qualified specialist who will take into account not only your complaints, but also your age. After evaluating all the indicators, the individual characteristics, he makes recommendations.

It should be noted that the increased level of the indicator is not a diagnosis, but only a pretext due to which it is worthwhile to carry out additional procedures for a more accurate assessment of the state of health. If the indicator is at a sufficiently high level, the specialist prescribes an MRI scan, an ultrasound scan, and a CT scan. Sometimes appoint examination with the help of X-rays.

A single blood test is not enough in this case. Additional procedures are necessary, only after this the specialist can make an accurate diagnosis.

Where to pass tumor markers and find out data about the norm?

In the modern world, the incidence of cancer has increased significantly, not only among people of older age groups, but also among young people.

Oncological markers make it possible to determine the presence, level of a tumor at the very beginning of its development or at the time of its development without obvious symptoms. Despite this, it is not necessary for each person to take an analysis. Consultation of an Israeli specialist

Terms of blood donation for analysis

In order for the results of the HE-4 tumor marker test to be as reliable as possible, it is important to follow certain rules before donating blood:

  • the blood for the HE-4 analysis of the tumor marker should be given in the morning;
  • In preparation for an HE-4 test, you should stop using any drugs three days before donating blood.
  • before submitting the biomaterial for research it is forbidden to smoke,
  • drinking should be discarded five days before the test is taken,
  • обязательно нужно уведомить доктора, какая фаза менструального цикла протекает в данный период.

Иногда анализ крови на маркеры HE-4 может быть назначен в детском возрасте. Тогда девочкам обязательно необходимо пить кипяченую воду. За полчаса перед сдачей крови следует выпить не меньше чем 0,2 л воды.

A number of recommendations should be followed, with which the test will only give accurate results:

  • a week before the procedure should exclude the use of alcoholic beverages, stop smoking,
  • analysis takes place in the morning, on an empty stomach,
  • if possible, it is necessary to exclude medication for 3 days. If this item cannot be applied, inform the attending physician about this,
  • it is necessary to know the exact phase of the menstrual cycle, this information is also necessary specialist.

The appointment of the procedure in childhood is quite rare. Before the procedure, the child should drink boiled water. The amount of fluid consumed varies from 200 ml.

Causes of errors

Any study in the presence of certain factors can give false results, both positive and negative. The HE-4 tumor marker may also be erroneous, for example, due to:

  • equipment malfunctions
  • mistakes of young professionals
  • non-observance of due rules when preparing for blood donation for analysis,
  • blood diseases.

If there is a certain impact of factors, a false result is possible. In case of imperfection, equipment malfunction, or poor quality work of laboratory assistants, non-compliance with recommendations regarding preparation for analysis, errors may occur.

Marker increase is observed in rare cases in the presence of fibroids, or uterine fibroids, cystic fibrosis. In the presence of pathological changes in the region of the liver, or testicles, of the small pelvis, a similar situation is observed.

False positive results can occur as well as false negative values.

If a woman is at risk, a negative indicator does not indicate the absence of the disease.

In order for a specialist to make an accurate diagnosis, it is necessary to undergo a series of procedures. In particular, a reliable assessment of a tumor marker is possible in cases of regular delivery. Thus, growth is determined, the dynamics of development.

With accurate diagnosis, a treatment plan is developed based on the individual characteristics of the patient.

Important! In case of early diagnosis, chemotherapy is used.

If the prescribed treatment does not prove to be effective, surgery is prescribed, the therapy assigned to the recovery of the body after this procedure.

If the prescribed treatment does not prove to be effective, surgery is prescribed, the therapy assigned to the recovery of the body after this procedure.

The favorable outcome of the treatment procedure depends largely on early diagnosis. After the retreat of the disease, experts recommend not to neglect the passage of regular research. Thus, timely detection of recurrence is possible.

It is worth remembering that increasing the value of the marker is not a reason to panic. Depending on the age category, specific menstrual cycle, the values ​​are interpreted by a specialist. Third-party factors also influence the increase in value, the risk of error should not be excluded. For an accurate diagnosis, doctors prescribe a number of procedures. This helps to identify and neutralize the pathogenic disease in a timely manner.

Decoding results

After the test, the results of the HE-4 oncomarker test are usually ready in two days. A good indicator is the reduced number of HE-4 tumor markers in the blood test, which means no malignant tumors.

After conducting a study on the HE-4 tumor marker, only a qualified specialist should perform the decoding of the data, taking into account the age group of the patient.

The marker HE-4 can be detected in the blood of absolutely all women. Optimal rates of HE-4 is calculated based on the age category of the patient. In the childbearing age, this rate in women should not exceed 70 pmol / l, but after menopause, its level can reach up to 140 pmol / l. Accurate diagnosis is not made, based solely on increased rates, but this suggests the need for additional research.

Deviations

When specialists in the blood find a deviation from the norm in the form of an increase in the number of HE-4 tumor markers, patients are prescribed the following diagnostic measures:

  • ultrasound (ultrasound),
  • magnetic resonance imaging (MRI),
  • computed tomography (CT),
  • radiography.

After analyzing the marker level, the results are not a reason for making an accurate diagnosis. All these values ​​can only indicate the need for a full survey.

When deciphering the analyzes of already adult women, a decrease in indicators is not envisaged; additional diagnostic measures are appointed only if an increase in the number of markers is detected. More accurate diagnosis requires the combined use of blood tests for tumor markers HE-4 and CA 125.

Tumor Marker Definition

In the human body there are substances in a small volume, which are called tumor markers. They are involved in various physiological and biochemical formations and are not dangerous in quantitative norm. Everything will be different if their volume begins to increase. This indicates the likelihood of malignancy. For example, the CA-125 tumor marker is most often used to determine ovarian cancer. But later it turned out that the HE4 oncomarker more accurately defines oncology.

This is a serous protein that blocks the enzyme proteinases, translated as "human protein - four appendages." In the required small amount, it is in the testicles and functions when sperm are produced. It is also present in the respiratory structure, fallopian tube and mucous membranes. But how exactly it functions and how it affects individual pepsins is still not clear.

HE4 benefits

At the same time, the tumor marker HE4 means a malignant process. It cannot be determined by a benign process or inflammation of the ovaries. This shows how effective HE4 is.

His predecessor, the CA-125 tumor marker, also aims to recognize cancer, but it has a small accuracy of determination. That is, the volume of CA-125 becomes larger in the final stages with proper diagnosis. And the volume of HE4 increases approximately three years before the exact definition of the disease.

Accordingly, with the help of a study, cancer can be detected at an early stage, while symptoms have not yet manifested. Despite this, the transcription of the HE4 tumor marker is not used to study ovarian lesions. He can not recognize the germ cell and mucoid cancer.

HE4 is used to observe women who have already started treatment. Accordingly, if this analysis during treatment is stopped, then the used therapy passes successfully.

By the number of this tumor marker, it is possible to determine the process of formation of secondary foci of tumor growth as a result of the divergence of cells from the initial focus to neighboring tissues or its renewal.

Testing for HE4

The causes of high mortality due to cancer are the definition of the disease in the final stages of its development. With the help of the analysis on HE4, it is possible to determine cancer in the early period, thereby reducing the probability of death. The tumor marker can be detected in blood taken from a vein. For the correct delivery of the analysis it is necessary:

  • Donate blood strictly on an empty stomach or four to five hours after eating. You can drink water, but coffee or juice is not recommended.
  • If possible, for several days (3-4 days) before taking the test, do not take any medication.
  • Do not drink or smoke before taking the test.
  • Women who start treatment are tested every three months. In the future, enough one - two times to check.

In some cases, the examination is prescribed to children. They need to drink boiled water for half an hour before putting the analysis. The average volume of water consumed should be 150-200 ml.

Women should be tested if there is pain in the pelvic region, the menstrual cycle is disturbed, and the appetite is low.

In the study it is important to identify a high level of tumor marker.

HE4 tumor marker: transcript

The rate depends on the gender, age of the patient. After the blood is tested for analysis, you must wait. The result will be ready after a couple of days.

The HE4 volume is recognized by special chemoluminescent examination.

The bottom line is this: a definite reaction occurs between the labeled compounds and the desired 4th protein. Then there is a change of all their inherent properties. The catalyst starts the glow reaction. Now, with the help of instrumental methods, the level of the tumor marker is determined and calculated.

The norms of men and women

The normal amount of protein-4 in women in the premenopause period is no more than 70 pmol / l, and after menopause it is slightly less than or equal to 140 pmol / l. The more these indications, the greater the likelihood of cancer of the ovaries.

But you should definitely know that there are age norms, that is, depending on age, the data changes. Therefore, it is better to find out all the information from your doctor. This is what HE4 tumor marker shows.

There is the following interesting fact. When HE4 was decrypted, the following data was obtained: the third part of the female half of the population has increased rates of this oncomarker, but the CA-125 most often remains in the permissible rate.

What is the norm of this indicator in men? It is at the level of 4 ng / ml and below. It should be alerted if it shows very high rates. This may indicate the development in the body of a dangerous cancer disease.

There is a change in the norm with age. After forty years in men, the rate will be 2-2.5 ng / ml, after sixty years - 4.5-6.5 ng / ml.

Statistics show that more and more men of different ages seek medical help. They have increased tumor markers in the blood and there is a pathology of the prostate gland.

Analysis Error

It should be borne in mind that the analysis of the tumor marker is not a basis for confirming or denying oncology. It is more correct to use HE4 with other analyzes. It is best to explore it with the CA-125. And also to carry out various types of diagnostics, both laboratory and instrumental.

Sometimes the high value of the HE4 tumor markers is caused by a non-malignant process. The analysis will have a false positive result for:

  • the presence of a systemic hereditary disease, which is explained by a change in the gene of the transmembrane regulator,
  • the presence of other inflammations of the urogenital structure,
  • chronic renal failure
  • ovarian cyst
  • myome

How to recognize the symptoms of cancer?

At the slightest disturbance in the body, you should consult a doctor. He will prescribe a tumor marker for epithelial ovarian cancer HE4. The rate or deviation from it will reveal quickly. At first, the symptoms may be completely absent. But in any case, the analysis should be carried out with:

  • ovarian disorders and menstrual problems in women
  • acute pain syndrome in the pelvic region,
  • deterioration of general well-being with reduced appetite,
  • sharp and gratuitous weight loss,
  • apathy.

When confirming the diagnosis, there is no need to panic, because cancer is now successfully treated. Of course, this is a test, but you can cope with it and get out of the fight as a winner.

Self-treatment is unacceptable, it is necessary to rely only on the recommendations of a specialist.

It will take patience and strength, because therapy is hard work, which has a long and unpleasant character.

Conclusion

An erroneous result may be if the tumor does not produce HE4 or it is not available in sufficient quantity to determine.

In spite of the fact that the analysis will show, you should not get upset and set a diagnosis for yourself. Medical specialists can determine the disease and prescribe a course of treatment, but only after a full examination.

Specificity

The tumor marker HE4 is often used for screening studies of ovarian cancer. Unlike CA-125, it is more specific and almost always indicates the presence of inflammatory processes in this organ. By specificity, it is the same as tumor markers: CA242 and PSA.

  • Specificity - 95%
  • Sensitivity - 76%

More often, when this marker is raised, it indicates that there is inflammation of the ovaries or oncology of this organ, if the indicator is greatly overestimated. But you need to take into account the remaining 5% - that is, donating this blood test, you should understand that it may not show 100% oncology.

Plus, it is necessary to take into account the probability factor - that is, the equipment can show both false positive and false negative results. Therefore, when screening, it is used only as an additional, but not the main method for detecting carcinoma.

Terms of analysis

NOTE! Blood is taken from a vein, and in order for the analysis to be most accurate, it is necessary to adhere to a number of rules, since the markers may increase under certain conditions.

  1. A blood test for oncology is given early in the morning on an empty stomach.
  2. For 8 hours you can not eat and drink sweet, carbonated drinks.
  3. For a week to give up alcohol.
  4. It is better not to smoke for 2-3 hours before analysis.
  5. Do not eat spicy, fried and very sweet food.
  6. For the day, do not have sex.
  7. Do not lift weights or do heavy physical work for 24 hours.
  8. When taking the children girls need to drink 1 cup of clean water for half an hour before tests.

You should not donate during the menstrual period, since the result will be improved and the accuracy of the test will be oiled. It is better to take on the 4-5 day after the end of the menstrual cycle. When re-analysis, the patient gives in 60-90 days at the request of the doctor.

Norm in women

  • Girls under 40 - 60 pmol / l
  • Postmenopausal women - 140 pmol / l

NOTE! Unfortunately, but in postmenopause and premenopause, the chance to detect cancer is only 16%. This is due to the fact that at this moment in the ovaries slightly other biological processes occur. Therefore, for a more accurate study, it is necessary to conduct another diagnosis.

Increased level of tumor marker can be when:

  1. Epithelial ovarian cancer.
  2. Endometriosis.
  3. Cirrhosis of the liver.
  4. Kidney inflammation.
  5. Cyst of the left or right ovary.
  6. Renal failure.
  7. Fibroma of the uterus.
  8. Myoma.
  9. Increased sugar ALT more than 30.
  10. After surgery on the ovaries, uterus.

When combined with the CA-125 marker, most women experience an increase in the HE-4 marker, but the second remains at a normal level. As you can see, the tumor marker is at least sensitive to cancer, but can increase due to many inflammatory processes in the ovaries, uterus and urinary system.

I have a non-4 tumor marker indicator: 46 - is it cancer or not?

Here it is necessary to take into account many factors, since even in a healthy organism, an increase in the marker does not always show cancer. The interpretation of the indicator should be carried out by a qualified doctor.

If the rate is too low, what does this mean?

Even if the level is very low, it does not show any deviations and it will be within the normal range, and only an increase in the level speaks of inflammatory processes.

Before taking or deciphering, explain to your doctor whether you have any concomitant diseases of the reproductive system, when you had menstruation last time and if you had any examinations: ultrasound, MRI, CT, biopsy, which can also slightly increase the rate.

ROMA1 and ROMA2

There is also a so-called ROMA index test - this is a specific algorithm for detecting cancer in postmenopause and in premenopause. Due to the fact that older women have a higher risk of becoming ill with oncology, this analysis was invented. The handover goes immediately to two oncomarkers: HE-4 and CA 125. Next comes the calculation by the algorithm, and two indices are written in the analysis:

IndexROMA1 - premenopause

  • less than 7.4% - low risk of oncology
  • more than 7.4% - high risk of oncology

ANDndex ROMA2— постменопауза

  • меньше 25,3% — низкий риск онкологии
  • больше 25,3% — высокий риск эпителиального рака

But not always for example ROMA1 with an increase in the rate indicates the presence of malignant cells in the ovaries, as many factors may indicate this.

Diagnostics

If this marker is elevated, it is necessary to conduct a more accurate survey.

  1. Delivery of the general and biochemical analysis of blood. Look at the balance of substances and cells in the blood, which can also indicate cancer.
  2. Examination by a gynecologist - view the cervix, for the presence of inflammatory processes.
  3. Ultrasound of the pelvis and abdomen.
  4. Radiography - exclude metastases in the lungs, if the tumor is detected.
  5. Biopsy - a piece of the tumor is taken from the ovary, and it is sent for histological examination to detect malignancy.

Prevention of ovarian cancer

  1. Try to dress warmly, so as not to chill the body.
  2. Sex only with a proven partner.
  3. After 45 years of age, undergo an annual examination by a gynecologist and take a general and biochemical blood test.
