Causes of acute leukemia in adults. Acute leukemia: life prognosis Acute leukemia chances

Acute leukemia (acute leukemia) is a severe malignant disease that affects the bone marrow. The pathology is based on a mutation of hematopoietic stem cells - precursors of blood cells. As a result of the mutation, the cells do not mature, and the bone marrow is filled with immature cells - blasts. Changes also occur in the peripheral blood - the number of basic formed elements (erythrocytes, leukocytes, platelets) in it falls.

With the progression of the disease, tumor cells go beyond the bone marrow and penetrate into other tissues, resulting in the development of the so-called leukemic infiltration of the liver, spleen, lymph nodes, mucous membranes, skin, lungs, brain, and other tissues and organs. The peak incidence of acute leukemia falls at the age of 2-5 years, then there is a slight rise at 10-13 years, boys get sick more often than girls. In adults, a dangerous period in terms of the development of acute leukemia is the age after 60 years.

Depending on which cells are affected (myelopoietic or lymphopoietic germ), there are two main types of acute leukemia:

  • ALL- Acute lymphoblastic leukemia.
  • AML- Acute myeloid leukemia.

ALL more often develops in children (80% of all acute leukemias), and AML- in older people.

There is also a more detailed classification of acute leukemia, which takes into account the morphological and cytological features of blasts. An accurate definition of the type and subspecies of leukemia is necessary for doctors to choose treatment tactics and make a prognosis for the patient.

Causes of acute leukemia

The study of the problem of acute leukemia is one of the priority areas of modern medical science. But, despite numerous studies, the exact causes of leukemia have not yet been established. It is only clear that the development of the disease is closely related to factors that can cause cell mutation. These factors include:

  • hereditary propensity. Some variants of ALL develop in almost 100% of cases in both twins. In addition, cases of acute leukemia in several family members are not uncommon.
  • Exposure to chemicals(particularly benzene). AML can develop after chemotherapy for another condition.
  • radioactive exposure.
  • Hematological diseases– aplastic anemia, myelodysplasia, etc.
  • Viral infections, and most likely an abnormal immune response to them.

However, in most cases of acute leukemia, doctors fail to identify the factors that triggered the cell mutation.

During acute leukemia, five stages are distinguished:

  • Preleukemia, which often goes unnoticed.
  • The first attack is the acute stage.
  • Remission (complete or incomplete).
  • Relapse (first, repeated).
  • terminal stage.

From the moment of mutation of the first stem cell (namely, everything starts with one cell) until the onset of symptoms of acute leukemia, an average of 2 months pass. During this time, blast cells accumulate in the bone marrow, which do not allow normal blood cells to mature and enter the bloodstream, as a result of which characteristic clinical symptoms of the disease appear.

The first "swallows" of acute leukemia can be:

  • Fever.
  • Loss of appetite.
  • Pain in bones and joints.
  • Paleness of the skin.
  • Increased bleeding (hemorrhages on the skin and mucous membranes, nosebleeds).
  • Painless swollen lymph nodes.

These signs are very reminiscent of an acute viral infection, so it is not uncommon for patients to be treated for it, and during the examination (including a complete blood count) a number of changes characteristic of acute leukemia are detected.

In general, the picture of the disease in acute leukemia is determined by the dominant syndrome, there are several of them:

  • Anemic (weakness, shortness of breath, pallor).
  • Intoxication (loss of appetite, fever, weight loss, sweating, drowsiness).
  • Hemorrhagic (hematomas, petechial rash on the skin, bleeding, bleeding gums).
  • Osteoarticular (infiltration of the periosteum and joint capsule, osteoporosis, aseptic necrosis).
  • Proliferative (enlarged lymph nodes, spleen, liver).

In addition, very often with acute leukemia, infectious complications develop, the cause of which is immunodeficiency (inadequately mature lymphocytes and leukocytes in the blood), less often - neuroleukemia (metastasis of leukemic cells to the brain, which proceeds like meningitis or encephalitis).

The symptoms described above cannot be ignored, since the timely detection of acute leukemia significantly increases the effectiveness of antitumor treatment and gives the patient a chance for a full recovery.

Diagnosis of acute leukemia consists of several stages:


There are two methods of treatment for acute leukemia: multicomponent chemotherapy and bone marrow transplantation. Treatment protocols (drug regimens) for ALL and AML are different.

The first stage of chemotherapy is the induction of remission, the main purpose of which is to reduce the number of blast cells to a level undetectable by available diagnostic methods. The second stage is consolidation, aimed at eliminating the remaining leukemia cells. This stage is followed by reinduction - a repetition of the induction stage. In addition, maintenance therapy with oral cytostatics is an obligatory element of treatment.

The choice of protocol in each specific clinical case depends on which risk group the patient belongs to (the age of the person, the genetic characteristics of the disease, the number of leukocytes in the blood, the response to previous treatment, etc. play a role). The total duration of chemotherapy for acute leukemia is about 2 years.

Criteria for complete remission of acute leukemia (all of them must be present at the same time):

  • absence of clinical symptoms of the disease;
  • detection in the bone marrow of no more than 5% of blast cells and a normal ratio of cells of other hematopoietic lineages;
  • absence of blasts in peripheral blood;
  • the absence of extramedullary (that is, located outside the bone marrow) lesions.

Chemotherapy, although aimed at curing the patient, has a very negative effect on the body, since it is toxic. Therefore, against its background, patients begin to lose hair, nausea, vomiting, dysfunction of the heart, kidneys, and liver appear. In order to timely detect side effects of treatment and monitor the effectiveness of therapy, all patients need to regularly take blood tests, undergo bone marrow studies, biochemical blood tests, ECG, echocardiography, etc. After completion of treatment, patients should also remain under medical supervision (outpatient).

Of no small importance in the treatment of acute leukemia is concomitant therapy, which is prescribed depending on the patient's symptoms. Patients may require transfusion of blood products, antibiotics, detoxification treatment to reduce intoxication caused by the disease and the chemotherapy drugs used. In addition, if indicated, prophylactic brain irradiation and endolumbar administration of cytostatics are performed to prevent neurological complications.

Proper patient care is also very important. They must be protected from infections by creating living conditions that are as close as possible to sterile, excluding contact with potentially infectious people, etc.

Patients with acute leukemia are transplanted with bone marrow, because only it contains stem cells that can become the ancestors of blood cells. Transplantation performed on such patients must be allogeneic, that is, from a related or unrelated compatible donor. This treatment procedure is indicated for both ALL and AML, and it is advisable to transplant during the first remission, especially if there is a high risk of relapse - the return of the disease.

In the first recurrence of AML, transplantation is generally the only salvation, since the choice of conservative treatment in such cases is very limited and often comes down to palliative therapy (aimed at improving the quality of life and alleviating the condition of a dying person).

The main condition for transplantation is complete remission (so that the "empty" bone marrow can be filled with normal cells). To prepare the patient for the transplantation procedure, conditioning is also mandatory - immunosuppressive therapy designed to destroy the remaining leukemia cells and create a deep depression of immunity, which is necessary to prevent transplant rejection.

Contraindications for bone marrow transplantation:

  • Serious dysfunction of internal organs.
  • Acute infectious diseases.
  • Recurrent leukemia, refractory to treatment.
  • Elderly age.

Prognosis for leukemia

The following factors influence the prognosis:

  • patient's age;
  • type and subspecies of leukemia;
  • cytogenetic features of the disease (for example, the presence of the Philadelphia chromosome);
  • body's response to chemotherapy.

The prognosis for children with acute leukemia is much better than for adults. This is due, firstly, to the higher responsiveness of the child's body to treatment, and secondly, to the presence in elderly patients of a mass of concomitant diseases that do not allow for full-fledged chemotherapy. In addition, adult patients often turn to doctors when the disease is already advanced, while parents are usually more responsible for the health of children.

If we operate with numbers, then the five-year survival rate for ALL in children, according to various sources, ranges from 65 to 85%, in adults - from 20 to 40%. In AML, the prognosis is somewhat different: five-year survival is observed in 40-60% of patients younger than 55 years, and only 20% of older patients.

Summing up, I would like to note that acute leukemia is a serious disease, but curable. The effectiveness of modern protocols for its treatment is quite high, and relapses of the disease after a five-year remission almost never occur.

Zubkova Olga Sergeevna, medical commentator, epidemiologist

Leukemia is a malignant pathology that affects the circulatory system. Its primary focus of localization is bone marrow tissue.

The disease has no age restrictions, but in more than 90% of detected cases, the disease affects adults. In the past few years, the statistics of leukemia cases has been steadily increasing.

Pathology can proceed both in acute and have a chronic form of the course. In the first case, its clinical manifestations will be more pronounced, in the second case, the symptoms are extremely blurred and it is not always possible to diagnose the disease in time.

The acute form of leukemia is characteristic of the elderly, while the chronic manifestation of blood cancer affects young and middle-aged people. It is in this situation that it is extremely important to carefully monitor the slightest manifestations of the disease.

First symptoms

In the vast majority of patients with this diagnosis at the initial stages of its progression, the process proceeds differently. The intensity of the manifesting signs is determined by the state of the body's immune forces and the general physical health of a person.

This symptom is considered one of the most non-specific and therefore almost always ignored up to a certain point. This condition is very close to the manifestations of a cold at the stage when nothing hurts yet, but the person understands that something is wrong with him.

There is muscle weakness, drowsiness, lethargy. Often this "set" is accompanied by swelling of the mucosa, headache, ocular tearing, characteristic of viral diseases.

The patient begins to take anti-cold drugs, due to their orientation they give some result, eliminating physical discomfort, which blurs the symptoms for an indefinite time, and the person continues to not notice a serious threat.

Anemia

Leukemia, especially its myeloid form, provokes a tendency to bleeding, the appearance of hematomas, bruises, even with a slight mechanical impact, which should not be normal.

The phenomenon is considered a consequence of a violation of the cellular structure of platelets, in which blood cells lose their natural coagulability. During this state, the number of red blood cells reaches an extremely low level. This is how anemia occurs. It is because of her that the skin becomes paler than usual, which directly indicates serious problems with hematopoiesis.

sweating

One of the main early signs of the development of a malignant anomaly of the blood. This is especially true in cases where, due to physiological and anatomical features, a person was previously not prone to sweating.

The phenomenon occurs spontaneously, cannot be corrected. Basically, it happens at night during sleep. Such sweating in oncological practice is interpreted as profuse and is the result of damaging processes in the central nervous system.

Patients with leukemia tissue fragments - the cause of infiltration of the outer epithelial integuments and glands that produce sweat secretion.

Enlarged lymph nodes

Submandibular, clavicular, axillary and inguinal nodal joints, that is, those areas where there are skin folds, fall under the damaging effect of progressive pathology. However, they are quite easy to spot.

Since cancer-affected leukocytes actively accumulate and develop further in the lymph nodes, their increase is an inevitable process. Abnormal tissues gradually fill immature forms, and the nodes increase many times in diameter.

They are characterized by an elastic and soft internal content, while mechanical pressure on the tumor is accompanied by pain of varying degrees of intensity, which cannot but alert a person and requires consultation of a specialized specialist.

If the lymph node is larger than 2 cm, this is far from the norm, but most likely a developing oncological pathology.

Enlargement of the liver and spleen

It is worth noting that these signs are quite specific and may have a completely different background. It is important to understand the borderline conditions of enlargement of these organs in order to adequately judge the possible risks of oncology.

As for the liver, its increase is not too pronounced and critical. With such a diagnosis, it almost never reaches large sizes. The spleen somewhat dominates in this regard - it begins to grow actively already at the initial stages of the course of the disease and gradually spreads to the entire area of ​​the left peritoneal zone.

At the same time, the organ changes its structure - it becomes dense in the center, and softer at the edges. It does not cause discomfort and pain, which makes it difficult to diagnose this anomaly, especially in overweight patients.

Main symptoms

As the disease progresses, the symptoms of its course become brighter. At this stage, it is extremely important to pay attention to secondary signs of leukemia, since untimely seeking medical help is the main cause of death in adults from the considered malignant pathology.

Bleeding

Blood leukemia in adults, regardless of its form, disrupts the normal processes of platelet production, which directly determine the quality of blood clotting. As the disease progresses, this condition worsens, as a result of which fibrin clots that can stop bleeding simply do not have time to form.

In this state, even shallow cuts and scratches are very dangerous. And nosebleeds are fraught with serious losses of blood mass.

Women on the background of the disease are characterized by heavy menstruation, cycle disorders and spontaneous uterine bleeding.

bruising

Bruises and bruises appear suddenly, and their nature of occurrence is not mechanical trauma to the affected tissue fragment. This is the specificity of the symptom, and the inexplicability of their appearance is the result of a low content of platelets in the blood plasma and the resulting low blood clotting.

Bruises can appear in any part of the patient's body, but their predominant number is in the upper and lower extremities.

Joint pain

Pain in the joints differs in varying degrees of intensity and is a consequence of a large concentration of diseased cells in the brain, in particular in those areas where their maximum density is concentrated - in the area of ​​​​the sternum and pelvic bone at the ilium.

As the stage of leukemia increases in an adult, cancer cells grow into the cerebral fluid, enter the nerve endings and cause local pain.

chronic fever

Many associate a chronic increase in the patient's body temperature with internal inflammatory processes, however, if this phenomenon does not have obvious symptoms, then with a high degree of probability, malignant oncological lesions of organs can be suspected.

A chaotic increase in the number of leukocytes will inevitably cause biochemical processes with a releasing action of components that activate the activity of the hypothalamus, which, in turn, is responsible for an increase in the patient's body temperature.

Frequent infectious diseases

Chronic cough, nasal congestion, become almost regular, especially in the acute form of the disease in adults.

The reason for this phenomenon is the low functional ability of leukocytes, which are responsible for the immunomodeling of cells. The body affected by leukemia can no longer qualitatively and quickly fight the pathogens of viral and catarrhal infections penetrating from the environment, and the disease becomes regular.

In this condition, the patient's microflora is disturbed, which further reduces susceptibility to SARS and colds.

Constant malaise

A constant feeling of fatigue and physical weakness even after a good rest, a feeling of indifference and depression associated with this state, are directly a consequence of the fall in the level of erythrocytes. This process occurs at lightning speed and progresses just as rapidly.

Often, against the background of this, appetite decreases, a person begins to lose body weight, since the tumor transformation of cancerous blood cells in an adult organism requires large energy resources. As a result, the patient becomes weak and exhausted.

Distinguishing symptoms by type

The clinical manifestations of leukemia in an adult may differ somewhat and have more non-standard manifestations depending on the type of disease. In addition to the general signs characteristic of the pathology, the following specific symptoms of the development of tumor processes in the blood were revealed.

Chronic myeloid leukemia

Manifestations of myeloid oncology in the chronic stage of the course in addition to the general signs of the disease are fraught with:

  • palpitations or vice versa, slow heart rate;
  • fungal infections of the oral cavity - stomatitis, tonsillitis;
  • renal failure - manifests itself, starting from the 3rd stage of the course of the disease;

Chronic lymphoblastic leukemia

It belongs to the group of non-Hodgkin manifestations of lymphoma, the main cause of which is a genetic factor. Against the background of the disease develop:

  • severe impairment of immune function- entail a sharp deterioration in the state of health and dysfunction of a number of important systems and departments of the body's vital activity;
  • urinary tract pathology- cystitis, urethritis are most often diagnosed, and only in the process of their therapy is the true cause of their appearance revealed;
  • tendency to fester- purulent masses accumulate in the area of ​​​​subcutaneous adipose tissue;
  • lung lesions- often they lead to death against the background of the main diagnosis - leukemia;
  • shingles- proceeds hard, quickly affects large areas of tissue, often passes to mucous fragments.

Acute lymphoblastic leukemia

The course of the disease is accompanied by the following distinctive features:

  • severe intoxication of the body- manifests itself in various kinds of viral, bacterial infections and inflammatory processes;
  • vomiting reflex-accompanied by an uncontrolled course. The composition of the vomit contains a large number of blood fragments;
  • respiratory failure and as a result, the development of heart failure.

Acute myeloid leukemia

The disease, unlike other types of leukemia, in adult patients develops extremely rapidly and already at the stage of tumor formation, symptoms associated with a particular type of cancer may be characteristic:

  • sharp, more than 10% of the total body weight, weight loss- weight loss occurs very quickly, the patient spontaneously loses fat mass after a couple of months;
  • pain in the abdomen- caused by the growth of parenchymal departments;
  • tarry stools- their cause is bleeding of the gastrointestinal tract;
  • high intracranial pressure- occurs due to swelling of the optic nerve and acute headache.

Leukemia is a general term for oncological blood pathologies. One of the most malignant is acute leukemia - a type of blood cancer, which is characterized by the rapid multiplication of immature forms of leukocytes that are unable to perform their functions. The prognosis of life depends on the stage of acute leukemia and the response to treatment. Approximately 90% of the disease occurs in adult patients. People over the age of 50 are much more likely to develop myeloid leukemia (acute or chronic).

There are several forms of leukemia, the prognosis for which is different. Children are more susceptible to acute lymphoblastic leukemia. In this case, pathological leukocytes are formed in the bone marrow, as well as in the lymph nodes. Blood cells undergo deformation and mutation. Adult patients are more likely to suffer from acute granulocytic leukemia. In this case, the affected white blood cells multiply in the bone marrow.

Lymphoblastic leukemia: prognosis

More than 75% of cancer cases are due to lymphoblastic leukemia. Children of two or four years of age are most susceptible to it, and boys get sick much more often than girls. The stronger the leukocyte level in the blood of a small patient during the examination, the more disappointing the scenario will be. Research confirms that toddlers and preschoolers with this form of cancer have almost twice the chance of survival as those older than six and younger than two."
At present, it is not established as a result of which factors the disease develops. Doctors put forward a version that this is some kind of chromosome anomaly. Acute leukemia develops, as a rule, haphazardly. It does not have any specific symptoms that are not related to other diseases.
It could be:

  • temperature rise;
  • fast fatiguability;
  • allergy;
  • pallor of mucous membranes;
  • earthy skin color.

Myeloid leukemia: prognosis

Myeloid leukemia appears under the guise of many diseases, which makes it difficult to diagnose it in time and worsens the prognosis of life. Myeloid leukemia is a cancer that affects the myeloid germ, in other words, the part of the bone marrow where leukocytes are formed. It occurs in acute and chronic form. It ranks as the second most common disease among oncological diseases in children. The frequency of its occurrence increases in the first 2 years of a child's life, and then in adolescence.

The main causes leading to myeloid leukemia are:

  • the action of certain chemicals, formalin and benzene are considered especially toxicogenic;
  • exposure to radiation;
  • taking cytotoxic drugs in unacceptably high doses;
  • genetic diseases such as Wiesler-Fanconi disease, Down's congenital pathology, Patau.

At the initial stage, there are no symptoms of cancer. It is this fact that makes it difficult to identify the disease in time and prescribe treatment.

Prognosis in children with acute lymphoblastic leukemia

Lymphoblastic leukemia is a malignant pathology of a lymphocytic germ, characterized by a slower course. Chronic disease lasts up to 20 years. Mature forms of lymphocytes are present in the blood, and thrombocytopenia and anemia are observed only in the last stage.

Not so long ago, making this diagnosis, doctors did not give any forecasts at all. Today, more than 70% of patients have a chance of a successful outcome. The development and course of the disease in children is determined by many factors. The most important of these is the age of the small patient and the diagnostic period (the time from the onset of the disease to its detection). The most unfavorable prognosis for the development of acute lymphoblastic leukemia concerns children younger than two and older than ten years.

Optimistic prognosis in those patients whose age is over two years, and the diagnosis is lymphoblastic leukemia type L1 acute period, and it was detected at an early stage. Girls with lymphoblastic leukemia are healed more often than boys.

The history of medicine does not know a single case when acute leukemia went away by itself. Without proper treatment, the disease entails only one prognosis - a fatal outcome.

The courses of chemotherapy carried out help to come to the conclusion that most of the young patients can live for about five years without a recurrence of the disease. But only after a few years can a full recovery be predicted.

Modern diagnostics allows timely detection of pathology in almost all cases. With timely diagnosis and proper treatment (irradiation, chemotherapy, bone marrow transplantation), the prognosis is favorable - 90% of patients have relapse-free survival for five years.

Prognosis of the course in acute leukemia in adults

It is very difficult to predict the result of treatment for such insidious diseases as oncology, in particular leukemia. The effectiveness of treatment depends on many, not only medical, factors. There is always a chance, even in very neglected cases. But doctors look at things realistically and with such a diagnosis they never give a 100% cure. A cancerous tumor behaves unpredictably: it metastasizes even after complete removal. Therefore, the earlier the disease was detected, the greater the chance of healing.

The prognosis of life depends on the treatment of acute leukemia in adults, and is determined by many factors:

  • the age of the patient;
  • the number of mature blood cells;
  • the chosen therapeutic regimen;
  • calculating the dose of a chemotherapy drug;
  • a competent approach will help ensure a long-term remission.

With a high lymphoblastic level, the chances of recovery fall significantly, and the treatment is stretched for a much longer period. Also, the percentage of survival of patients is affected by the type of cellular damage, concomitant diseases and the positive response of the body to chemotherapy.

Modern complex treatment leads to stable remission. An adult under 60 can live for about six more years. The older the patient, the less chance he has of recovery. Life expectancy of up to five years in patients over the age of sixty does not exceed 10% of patients.

The prognosis for chronic forms is more encouraging. Unlike myeloid, adult lymphoblastic leukemia (malignant pathology of a lymphocytic germ) is characterized by a slower course. Chronic disease lasts up to 20 years. Mature forms of lymphocytes are present in the blood, and thrombocytopenia and anemia are observed only in the last stage.

If there is no relapse within five years, then you can hope for recovery. A relapse that does not occur within two years may signal a stable remission. Proper treatment, adequate provision of the body with vitamins, taking prescribed medications will help prolong life by more than 10 years.

In case of any form of acute leukemia, both in adults and in children, the support of relatives and friends provides invaluable assistance. It is very important not to succumb to fear and despair, this will give the body additional strength to overcome the disease.

So, when passing the next examination, the attending physician makes you a terrible diagnosis of "Leukemia", acute or chronic - you should not fall into despair, because there are many new different methods of treatment, medicines, which allows you to look optimistically at the prognosis for the treatment of this serious disease. In our article, we will try to figure out what kind of disease it is and how to treat it.

Leukemia (another name is leukemia) is a malignant disease of the human bone marrow, in the people it is also called “blood cancer”. The root cause of the disease is a violation of the process of hematopoiesis in the body: immature blood cells are produced in the bone marrow, which are called blast cells. As a rule, these are the precursors of white blood cells. Blast cells, due to uncontrolled reproduction, as they accumulate, do not allow the bone marrow to produce normal blood cells. These malignant cells accumulate in the kidneys, liver, spleen and other organs and cause disruption of the blood supply to the organs.

Due to the fact that in the human body there are 2 different lines of hematopoiesis, there are two main types of leukemia:

  • Lymphoblastic, because formed by blast cells, precursors of lymphocytes;
  • Myeloblastic, because based on leukocyte precursors.

The term acute leukemia means an aggressive form of the course of the disease, when the disease develops at a rapid pace.

The most common disease is acute lymphoblastic leukemia, which accounts for about three-quarters of all malignant diseases of the hematopoietic system. Acute and chronic leukemias occur on average in four cases per 100,000 people. Children make up about a quarter of the total number of cases. The vast majority of children suffer from this disease before the age of 14, boys are more susceptible to it.

Stages of leukemia

There are three stages of acute leukemia:

  • Initial - the symptoms are not expressed or "disguised" as other diseases, for example, SARS.
  • Expanded - all typical signs of the disease "Acute leukemia" are present, the symptoms are pronounced. At this stage, basically, remission or complete cure of the disease occurs.
  • Terminal - the stage of deep inhibition of hematopoietic functions.

disease factors

In general, the causes of this disease, unfortunately, have not been found. There are a number of dependencies on factors that are the causes of the disease in some cases:

  • Chemotherapy given to treat another type of cancer increases the risk of the disease.
  • Heredity - the likelihood of the disease increases due to the presence of genetic disorders and the presence of the disease in relatives.
  • Smoking.
  • Radiation exposure, etc.

However, there are many patients with leukemia who did not have established risk factors for the disease, the causes of the disease remain unidentified. Science does not stand still and perhaps in the near future the answer to the question of the causes of the disease will be found among scientists.

Acute leukemia. Symptoms

Symptoms in adults and children are practically the same. The only difference is that in adults with acute leukemia, it most often acquires a chronic form, which means that the onset of the disease is often camouflaged and is expressed only in increased fatigue and frequent infectious diseases.

General symptoms

Common symptoms characteristic of any stage are:

  • Weight loss without any reason.
  • Complaints about the deterioration of health, the patient is often tired.
  • Attacks of weakness, apathy, the patient may suddenly want to sleep.
  • Feeling of heaviness in the abdomen, mainly in the left hypochondrium.
  • More frequent infectious diseases.
  • Increase in sweating.
  • Unreasonable increase in body temperature.

Associated symptoms

Such symptoms do not directly indicate that a person is sick with leukemia, as they are also characteristic of other ailments, but they are included in the clinical picture of the disease:

  • Pale skin (due to anemia).
  • Dyspnea.
  • The gums may bleed, bruises all over the body, nosebleeds may suddenly bleed.
  • Headache.
  • Visual impairment.
  • Nausea and convulsions.
  • Poor coordination when walking.
  • Pain in the bones and joints.

Diagnostics

With the diagnosis of "Acute leukemia", the diagnosis is carried out in several stages.

The first and most obvious step in diagnosing leukemia is a clinical blood test. Deciphering the hemogram shows how far the progress of the disease has gone. The blood picture shows the presence of pathological changes in the composition of the blood: low levels of red blood cells and platelets, the presence of blast cells.

At the second stage, the patient is admitted to the hospital and the attending physician prescribes a puncture of the bone marrow and cerebrospinal fluid for laboratory studies of their composition.

The third stage is to identify the effect of the disease on other human organs through ultrasound, computed tomography, etc.

Treatment

Treatment of acute leukemia usually consists of three stages:

  • Achieving a decrease in the number of blast cells to a level safe for health and the onset of remission. Chemotherapy is carried out with special drugs (cytostatics) lasting several weeks, which destroy malignant blood cells.
  • Destruction of residual abnormal blast cells to avoid recurrence of the disease.
  • Maintenance therapy.

Unfortunately, acute leukemia, despite treatment, has an unpleasant feature - relapses of the disease, which occur quite often, in this case, bone marrow transplantation is used as the most effective treatment.

Complications

Despite the fact that chemotherapy is highly effective, however, it has a number of side effects. So, during its implementation, hematopoiesis is suppressed, the number of a person’s own platelets drops sharply and bleeding may occur. In order to prevent such problems, transfusions of donor blood and their components - platelets, erythrocytes are performed. Among the side effects, patients often complain of nausea, vomiting, hair loss, allergic reactions to chemotherapy drugs.

During treatment, the body's resistance to various infections decreases sharply, and patients are prevented from infectious diseases by courses of antibiotics, etc. For such patients, any infections are dangerous, as a result, patients are limited in contact with the outside world.

Forecast

The main questions in the diagnosis of "Acute blood leukemia": How long do they live with such a disease? Can it be cured? However, the answer to them is not so simple at first glance. With a diagnosis of acute leukemia, the prognosis of life expectancy depends on many factors: this is the type of leukemia, the stage of the disease, the age of the patient, the body's susceptibility to chemotherapy treatment, the presence of concomitant diseases, etc.

For children, the prognosis for treatment is more favorable. Firstly, they are more often examined, which makes it possible to identify signs of the disease in the early stages. Secondly, the young body is more susceptible to chemotherapy and the results of treatment will be much better, and thirdly, the vast majority do not have already accumulated diseases.

A characteristic feature of acute leukemia is its rapid development, and the longer a person does not take action to treat it, the less likely he is to survive in the future.

In general, the disease is characterized as severe, but now they have learned how to cure it, while about 90% of patients can achieve complete remission. However, it is important to understand that during the period of complete remission, there may be relapses of the disease, which occur in approximately 25% of cases. In the absence of relapses within 5 years, it is considered that the disease was completely cured.

Oncological diseases of the blood are classified as life-threatening diseases. One of these pathologies is acute myeloid leukemia, the prognosis of life in which directly depends on early diagnosis. The disease is more susceptible to older people over 65 years of age. Pathology is characterized by an acute course and the complexity of detection at the initial stage.

Description of pathology

Acute myeloid leukemia is a disease also called leukemia, in which a malignant change in the meiloid blood germ occurs. Altered blood cells are capable of rapid reproduction and very quickly crowd out healthy cells, spreading throughout the human body. Unlike the chronic form, the acute form has a more unfavorable prognosis.

With a disease, pathological blood cells cannot perform all their intended functions, as a result of which malfunctions occur in the work of all human organs and tissues. Pathology is extremely difficult to diagnose at the initial stage. The determining factor for successful treatment is early diagnosis.

Causes of pathology

Like any cancer, leukemia can develop in anyone, regardless of gender and age. Scientists have not yet determined the mechanism for the development of these diseases, but doctors believe that there is a certain risk group, which includes people with the following factors:

  • genetic predisposition.
  • Postponed chemotherapy.
  • Living in ecologically unfavorable areas.
  • Congenital genetic pathologies.
  • Drug abuse.
  • Chronic toxic poisoning of the body.
  • oncogenic viruses.
  • Exposure to radiation.

Particular attention to their health should be given to people in whose families this pathology has already been observed. With a high degree of probability, pathology can manifest itself in the next generations. It is recommended that such patients be regularly tested for AML.

Symptoms of pathology

Acute myeloid leukemia has no characteristic symptoms. It can go completely unnoticed in the early stages. As the number of healthy blood cells decreases, the patient may experience the following abnormalities:

  • Paleness of the skin.
  • Chronic fatigue.
  • Increased bleeding.
  • Pain in the bones.
  • Decreased immunity.
  • Sudden unexplained weight loss.

These symptoms may indicate other abnormalities in the body, for this reason, patients do not always go to the doctor, attributing malaise to colds, fatigue, beriberi, and other non-life-threatening conditions. Usually, the disease is diagnosed with a sharp jump in temperature, in which the patient is called to a doctor or emergency room. It is impossible to determine leukemia by external signs, the diagnosis is made only according to the results of tests and other diagnostic procedures.

Symptoms in children can differ significantly from the manifestation of the disease in adults. The child must be shown to the doctor if he has the following changes:

  • Decreased memory, absent-mindedness.
  • Constant weakness and apathy.
  • Pale skin and lack of appetite.
  • Lack of desire to play with peers.
  • Frequent colds.
  • Frequent unreasonable temperature jumps.
  • Pain in limbs.
  • Shaky gait.
  • Pain in the umbilical region.

If the disease is not detected in the early stages, the child may die within a few weeks after the onset of leukemia. For this reason, a child's blood test should be done if any of the above ailments occur. In this case, time is not a healer, but a killer. Particular attention should be paid to children aged 3 to 6 years. It is during this period that the risk of cell degeneration is high.

Diagnosis of pathology

Diagnosis of the disease includes the following series of procedures:

  • Blood test (general, biochemical).
  • Flow cytometry and microscopy.
  • Ultrasound of internal organs.
  • X-ray.

Most often, the diagnosis is not difficult, especially if the disease is already progressing and the bulk of healthy blood cells have been destroyed. In this case, the patient is prescribed treatment, before which a series of examinations must be completed to assess the functioning of the heart, brain, nervous system and internal organs.

Treatment of pathology

The main treatment for leukemia in adults and children is chemotherapy, which destroys pathological cancer cells. The course of treatment is divided into two stages. The first stage is aimed at the destruction of cancer cells by taking certain groups of drugs. The second stage is the prevention of recurrence of the disease and may include various methods up to stem cell transplantation. The duration of therapy can be up to 2 years.

Chemotherapy often causes side effects. Patients may not tolerate treatment well. They feel nauseous and unwell. During this period, it is important to follow all the recommendations of doctors. In especially severe cases, treatment is carried out with a permanent stay of the patient in the hospital. Bone marrow transplantation is considered the most effective method of preventing recurrence.

According to statistics, 90% of patients who are diagnosed with pathology in the early stages fully recover. When acute myeloid leukemia is detected, the prognosis of a person's life depends on the individual characteristics of the organism, the type and stage of the disease. In the middle stages of the disease, the survival rate reaches 70%, and the probability of recurrence reaches only 35%. Doctors give the most favorable prognosis to children of childhood. Survival of children reaches 90%.

In addition to drug treatment, patients are recommended a complete change in lifestyle. In AML, proper nutrition is of particular importance. Food should be saturated with vitamins and useful microelements.

It is also necessary to enrich the blood with oxygen, and for this it is necessary to engage in light sports or exercise therapy.

Also, according to oncologists, the psychological mood of the patient is very important in the treatment of any type of cancer. According to the internal statistics of cancer centers, survival is much higher in patients who are cheerful, optimistic and confident in their recovery. The environment also plays a big role. If relatives support the patient, give him hope and fight with him, the chances of survival increase significantly.

If treatment is not carried out, the patient's life expectancy most often does not exceed 1 year, while after chemotherapy there is a chance to live for many more years. Survival of patients is estimated in the first 5 years after treatment.

Prevention of pathology

There are no specific measures to prevent leukemia. The only thing that will help to suspect and identify the disease in a timely manner is regular testing and preventive examinations. Also, doctors advise to lead a healthy lifestyle, give up bad habits and eat right.

In addition, it has been proven that cancer often occurs in people who abuse drugs and self-treat with antibiotics and other groups of drugs. For this reason, beware of buying and using advertised dietary supplements, drugs, and other products without consulting a doctor.

Blood cancer is one of the ten most common cancers. According to statistics, pathology is more often diagnosed in men. The prognosis for survival is estimated in the first 5 years after treatment. If the patient does not relapse during this period, there is a good chance that the disease will never return. It is very important for chemotherapy patients to undergo regular screening according to the prescribed schedule.
