Symptoms of leukemia in children. Blood test for leukemia

Chronic leukemia

With this type of disease, blood cells have time to grow, but cannot fully perform their functions.
A blood test shows the presence of a high number of white blood cells, but these cells cannot protect the child’s body from infections. After some time, there are so many granule cells that normal blood flow is disrupted. Symptoms of leukemia in children do not appear when it is chronic. This disease can be discovered completely by accident during a laboratory blood test for another disease.

Chronic leukemia stages have the following:

1. Monoclonal. Only one clone of pathological cells is present. This phase can last quite a long time, for many years, and is characterized as benign.
2. Polyclonal. At this stage, secondary clones appear. It is characterized by a fast flow. A large number of blasts are formed, and a crisis ensues. It is at this moment that more than eighty percent of patients die.

Benefits of onco

The success of oncology treatment greatly depends on the level of the clinic. And it’s not just about the professionalism of doctors and specialists conducting diagnostics. All therapeutic procedures must be performed using modern and high-tech medical equipment. The same applies to devices on which diagnostics are carried out. The data obtained with their help must be as accurate as possible so that the doctor can determine the location of the lesion and the stage of oncological pathology. And don’t forget about patient comfort. Diagnosis and treatment of oncological diseases takes a lot of time. Patients often have to spend the whole day within the walls of a medical facility, and some patients are undergoing inpatient treatment. Therefore, it is important that the environment and atmosphere be as favorable as possible. Onko took into account both his own 30 years of experience and the experience of foreign medical institutions. This allows us to diagnose cancer tumors and treat cancer patients with maximum efficiency, safety and comfort. See for yourself:

1. Each of our doctors is a highly qualified specialist with many years of experience both in Russia and in hospitals in the USA, Europe and Israel. We employ leaders of domestic medicine, as well as competent international consultants.
2. Diagnostics and therapeutic procedures are carried out in beautiful and cozy rooms. We have decorated our departments in a stylish design so that the interior looks as little as possible like a hospital room. Also for patients and their accompanying people there is a café and a restaurant on the roof with panoramic views of the city.
3. High safety and quality levels have been repeatedly confirmed by numerous certificates and awards. We carry out our activities in strict accordance with domestic and international standards, which allows us to minimize side effects and significantly increase the chances of recovery.

A little about the problem

Leukemia is a disease of the circulatory system. It is considered malignant. The reproduction and increase in leukocytes in the blood, bone marrow, and internal organs cannot be controlled. Initially, the tumor grows in the bone marrow, and then begins to “attack” the blood circulation.

As the disease progresses, it entails the appearance of other ailments associated with increased bleeding, internal hemorrhages, weakened immunity, and infectious complications.

In children, this disease is considered from the point of view of the mutation of healthy cells into pathological ones. Every day there are more and more of them. Patients may develop different types of deficiencies of some blood cells.

When to see a doctor

You should seek help from an oncohematologist if your health condition worsens if the following symptoms and signs are present:

• a sharp deterioration in health;
• unreasonable increase in body temperature;
• the appearance of rashes and bruises on the body;
• poor wound healing;
• pain in bones and joints;
• symptoms of anemia;
• hemoglobin levels and immunity are reduced.

Signs of deteriorating health in any case are a reason to contact the oncology center so that the doctor can prescribe additional tests and adjust the treatment.

General blood analysis

A general analysis can determine the presence of many diseases, inflammations and abnormalities in the functioning of internal organs and body systems. If the picture of the main elements in the analysis does not change, then the body works without deviations or disturbances. The following elements are taken into account for diagnosis:

• An increased ESR is observed - this indicates the presence of possible pathologies. To confirm blood cancer, you need to compare other indicators.
• White blood cells may be higher than normal or lower. In acute or chronic leukemia, the level depends on the stage of the process and the form of the pathology. Acute leukemia is characterized by aggressive cell division, which is expressed in an increase in the rate from normal. In a preschool child and a teenager, there is often a difference in the readings of leukocyte levels.
• Identification of cells with different sizes indicates the presence of anisocytosis.
• With leukemia, platelets are reduced by 10-15 times (the norm is 180-320). The initial stage may show normal levels.
• A decrease in red blood cells to 1-2*109/l indicates an oncological process in the body. The cell is responsible for transporting oxygen to tissues and organs. A lack of transport provokes shortness of breath and headaches in humans. The malignant process at an early stage does not affect the number of red blood cells in the blood.
• Reticulocytes are the germ cells of red blood cells. A low rate is present at an early stage of the tumor.
• Hemoglobin decreases in later stages of the disease. A reading of 50 or 60 g/l is considered the main sign of leukemia. But for this, the doctor excludes the reasons for the decrease associated with other diseases - deficiency of vitamin B12 with iron and severe bleeding.
• The absence of basophils and eosinophils indicates the presence of oncology that has affected the body’s hematopoiesis.

Clinical analysis is carried out in the same way for patients, regardless of age. This type of diagnosis is a mandatory event in the anamnesis collection program. In children, acute leukemia is lymphoblastic in nature, in adults it is mainly myeloblastic. Chronic leukemia occurs in people over 45 years of age.

Leukocytes

White blood cells are cells responsible for protecting the body from infectious and viral substances in the body. During the disease, the shape and structure of leukocytes undergo changes that affect their functionality. The disease can increase or decrease the number of cells. A blood test with bone marrow puncture allows you to detect the extent of damage to the body.

• General blood analysis

Any changes in indicators indicate the presence of the disease. Lymphocytes are heterogeneous in structure and differ in appearance. Low or elevated levels (leukocytosis) not only with leukemia. This is possible during other diseases - internal inflammation or viral damage. There is an example of the course of the disease against the background of a normal number of lymphocytes. But the leukocyte system shifts towards agranulocytes or granulocytes. Granulocytes mainly increase during an infectious disease.

Platelets

Platelets in the blood circulation perform an important function - they stop bleeding. When a vessel is injured, the system quickly forms a blood clot to stop bleeding. Normally, they should be contained from 180 to 360 in men and women. Leukemia affects differently - an increase (thrombocytosis) or a decrease (thrombocytopenia) is possible. A dangerous diagnosis is thrombocytopenia - decreased clotting function (DIC syndrome).

A decrease in platelets is possible with leukemia, hepatitis and systemic lupus erythematosus. Increased levels occur with erythremia, cancer of the pancreas, and after surgery.

Platelets in the blood

Red blood cells and hemoglobin

Red blood cells contain hemoglobin to transport oxygen to human tissues and organs. The level of red blood cells depends on the amount of hemoglobin. Normally there should be 4-5*1012/l. In the last stages of leukemia, the rate drops to 1-2*1012/l.

A decrease in hemoglobin causes an acute state of anemia, which is characterized by the following symptoms:

• You feel very tired and have decreased performance.
• The skin becomes dry and pale.
• Nail plates become brittle and thin, hair falls out.
• Light physical activity is accompanied by rapid heart rate and shortness of breath.
• There is a change in taste preferences.
• There are extraneous noises in the ears, attacks of nausea and dizziness.
• Unstable emotional background.

These symptoms worsen the patient’s condition, complicating the treatment process.

Hematocrit

Hematocrit is the ratio of red blood cell volume to plasma. The indicator is directly related to the number of red blood cells. The disease affects the entire hematopoietic composition.

Hematocrit helps detect the degree of anemia. The development of anemia reduces the amount to 25% and below. Severe blood loss with blood transfusion does not take into account hematocrit data due to the late reaction to the change of basic elements. You also need to take the test correctly, since the value changes depending on the position of the body.

ESR during illness

ESR is the value of the erythrocyte sedimentation process. The speed of this process is taken into account. Against the background of cancer, the picture does not look the same as in a normal state. Usually the speed increases. This is due to a disruption in the functioning of the immune system and the presence of a secondary infectious lesion. Based on this value, the doctor can understand the patient's condition.

Leukocyte formula

Diagnosing a patient with leukemia also includes assessing the leukocyte count. It is not the number of leukocytes that is taken into account here, but it is important to identify a qualitative change. The quantity often remains unchanged, but there is a qualitative imbalance. The analysis shows mature and young forms, without the presence of intermediate forms.

Oncology provokes a decrease in reticulocytes. The peculiarity of the leukocyte picture depends on the type of leukemia - an increase or decrease is possible.

Analysis in children

Children are susceptible to acute forms of the disease. The age group at risk is from 2 to 5 years. In the chronic type, symptoms are often not detected, but the disease can be determined by the values ​​of the main blood elements. The development of a malignant tumor can be recognized by the following signs:

• A sharp decrease in the level of hemoglobin with red blood cells;
• Red blood cells settle at a high rate;
• The number of reticulocytes decreases;
• Unstable leukocyte count;
• Platelets shift towards decrease.

Doctors recommend taking an annual blood test to determine the clinical picture and tumor markers.

Causes and risk factors

The etiological factors that inevitably become the “trigger” for malignant cell mutation have not yet been precisely established. However, the risks of developing acute leukemia increase significantly if:

• radiation exposure to which a person is exposed;
• infection with certain viruses that suppress the immune system (Epstein-Barr disease, T-lymphotropic virus, etc.);
• unfavorable heredity;
• smoking tobacco;
• prolonged exposure to certain chemical compounds, including medications;
• stress, depression;
• environmental pollution.

Stages of acute leukemia

There are only three of them:

1. Initial stage. During this period, all biochemical blood parameters may be normal or slightly change. A slight weakness appears, chronic diseases, bacterial and viral infections return.
2. Expanded stage. During this period, with a disease such as blood leukemia, the symptoms are pronounced. There are two options for getting out of this situation: there is an exacerbation of the disease or remission. During an exacerbation, a transition to the terminal stage occurs; during remission, it is necessary to wait time. Only after five years or more can we talk about a complete cure.
3. Terminal stage. The hematopoietic system is completely suppressed, and there is a high probability of death.

Treating oncology under compulsory medical insurance – what is needed for this?

You can receive FREE medical care at the Oncology Center under the State Guarantee Program of Compulsory Medical Insurance (Compulsory Medical Insurance) and High-Tech Medical Care.

The service is valid for all Russian citizens.

To find out more details, as well as for what nosologies and services this program works, please call +7, or you can read in more detail here.

Treatment and diagnosis of oncology are expensive medical services. The examinations alone cost a lot of money, and this is only the beginning of an already difficult path. Therefore, many patients are forced to postpone cancer treatment, since financial losses can literally ruin them. In this regard, the Sofia Clinic offers a number of services under the health insurance policy. Free cancer treatment under compulsory medical insurance is available to all Russian citizens. First of all, patients with very serious diagnoses, for whom treatment is a matter of life and death, can count on it. Such cancer patients are provided with quotas, which are financed from the federal and local budgets. As part of treatment under compulsory medical insurance, the following procedures are performed:

• PET/CT;
• radiation therapy;
• chemotherapy;
• IHC;
• surgery.

The decision to provide free oncology treatment under compulsory medical insurance is made by three commissions - the clinic, the health department and the medical institution itself. You can shorten this path if you immediately contact us and ask what procedures our clinic issues quotas for. The doctor (therapist or oncologist) will prepare a statement with the diagnosis and information about what diagnostics you have already undergone. You will need to submit to the regional health authority:

• medical direction;
• application for treatment of cancer under the compulsory medical insurance policy;
• Russian passport and insurance policy;
• SNILS;
• consent to the processing of personal data;
• pension certificate (for pensioners).
