Symptoms of leukemia in children and adults, treatment,forecast

Update: October 2018

Leukemia is a cancer that is
a type of cancer of the blood or bone marrow characterized by
патологическим увеличением количества лейкоцитов (белых cell) в
blood. About 90% of leukemia is diagnosed in adult patients. AT
In 2000, the diagnosis of leukemia worldwide was confirmed
approximately 256,000 patients. Of these, from the disease (and
its complications) died 209,000.

About every 4 minutes in the US, leukemia is confirmed in
очередного the patient. AT данный момент в США проживает более 1
a million people suffering from some form of blood cancer, including
числе leukemia Have людей старше 50 лет значительно возрастает частота
incidence of chronic lymphoblastic and acute myeloblastic
leukemia. Старше 65 лет – хроническим миелобластным leukemia.

Europeans remain the most susceptible to the disease (13.6 per
100 000 population). The lowest incidence of leukemia
It is celebrated among Asians and Pacific Islanders (7.4 per
100,000), as well as among American Indians and representatives
Alaska’s indigenous nationalities (7.3 per 100,000).

Leukemia in children

Leukemia is the most common form of cancer in children and adolescents.
occupying in frequency, in different countries, one of the three leading
positions. Approximately 75% of children’s leukemias are acute.
lymphoblastic leukemia. This form is more often diagnosed in children
age from 2 to 4 years. Boys are sick more often.

Acute myeloblastic leukemia takes up most of the remaining
25%. This type is common in a wider age range.
but its detection rate increases slightly in the first 2 years.
life as well as adolescents.

AT период с 2006 по 2010 годы частота развития острого
lymphoblastic leukemia among teenagers 15-19 years old exceeded twice
частоту острого миелобластного leukemia AT то же время, в возрастной
group from 25 to 29 years, the incidence of acute myeloblastic
leukemia was 57% higher than lymphoblastic.

The reasons

succeeded. There is some association of the disease with chromosomal
anomalies. AT частности, у всех больных хроническим миелобластным
leukemia and in some patients with the acute form of this disease in
leukocytes and bone marrow pathological is detected
�”Philadelphia chromosome”. This pathology belongs to the category
acquired. It is not innate and not transmitted from
parents to children. Symptoms лейкоза

An association with acute myeloid leukemia of such
diseases like:

  • Down syndrome;
  • Bloom syndrome;
  • Anemia Fanconi;
  • Синдром ATискотта-Олдрича и другие иммунодефицитные

Risk factors for leukemia are:

  • Radiation. People exposed to high doses of radiation
    have an increased risk of developing various forms of leukemia. AT данный
    The moment is a series of studies designed to determine the degree
    X-ray effects (X-ray examination and
    computed tomogram) for the development of leukemia;
  • Smoking increases the risk of developing acute myeloblastic
  • Petrol. Prolonged exposure to gasoline vapor increases the risk
    развития хронического или острого миелобластного leukemia;
  • Chemotherapy. Cancer patients receiving treatment
    special anti-cancer drugs have an increased risk
    развития острого миелобластного или лимфобластного leukemia;
  • Myelodysplastic syndrome and other hematological

The presence of one or even several factors not listed

Symptoms лейкоза варьируют в зависимости от типа и течения
diseases. Leukemia is classified into 4 main groups:

  • Acute Myeloblastic Leukemia
  • Chronic myeloblastic leukemia
  • Acute lymphoblastic leukemia
  • Chronic lymphoblastic leukemia

In addition, the course of leukemia depends largely on such factors
as the age of the patient and the cause that led to the disease.

Symptoms common to all types of leukemia are:

  • Frequent infectious diseases
  • Cold, fever
  • Chills
  • Loss of appetite, exhaustion, weight loss
  • Abdominal pain
  • Haveвеличение лимфатических узлов
  • General malaise
  • Frequent pain in bones and joints

Early symptoms of leukemia

The first symptoms of leukemia are non-specific and may not
perceived as a serious disease.

The onset of leukemia usually resembles a cold. In addition to the symptoms
listed above, the patient notes the appearance of a rash in the form
small red spots on the skin and an enlarged liver or spleen.
Usually this is enough to seek help from a doctor.
Characteristic additional symptoms for leukemia at this stage
are anemia and excessive sweating.

Symptoms лейкоза у детей

When diagnosing acute leukemia symptoms in children
appear as neurological disorders (drowsiness,
lethargy, loss of appetite, lack of body weight), after which
child’s condition is abrupt characteristic deteriorates and develops
picture of the disease.

If children with leukemia are suspected, symptoms may appear in

  • Vomiting
  • Loss of appetite
  • Weight loss for no apparent reason.
  • Headache
  • Uncontrolled seizures accompanied by skin manifestations.
    (subcutaneous hemorrhage)

In some cases, there is an increase in the liver and spleen,
which is externally manifested by bulging and thickening of the abdomen.

Children with leukemia are more susceptible to various
infectious diseases, while the use of antibacterial
drugs may not lead to improvement in the patient.

Such patients are more difficult to tolerate even minor scratches and
cuts. Blood coagulates much longer than healthy
human, which leads to frequent bleeding.

If a child with leukemia has pain in the joints and
bones, this may indicate the spread of cancer cells in
these areas of the body.

Symptoms of acute leukemia include:

  • Headaches
  • Vomiting
  • Confusion
  • Decreased muscle tone, inability to control movements
  • Cramps

in patients with chronic leukemia, symptoms appear only in late
stages, which leads to late diagnosis. Based on
personal experience and on numerous studies, researchers
found out that abnormal leukocytes are found in the blood
patients already 6 years before the development of clinical manifestations

Chronic leukemia symptoms develop
gradually, which makes the disease unlike other types
cancer. The initial signs of chronic leukemia are:

  • Frequent infectious diseases (reduction of
    gamma globulins responsible for maintaining the immune system
    leads to the development of its failure and makes it impossible
    resistance to pathogens)
  • Bleeding, difficult to stop bleeding (due to

  • Haveвеличение селезенки
  • Feeling of pain in the stomach, rapid saturation
  • Unreasonable weight loss

(in addition to those described above):

  • ATысокий уровень лейкоцитов в крови и костном мозге
  • Excessive sweating, especially at night
  • Headache fever
  • Paleness of the skin

The only early sign of chronic lymphoblastic
Leukemia is an elevated level of lymphocytes in the blood. As
disease progression, patients report worsening
well-being and swollen lymph nodes.

prolonged erection (priapism) and the development of stroke.


Treatment лейкоза должно проводиться только в специализированных
centers by a doctor who has the appropriate certificate. If you run
these rules are not possible, the attending physician should
be sure to discuss and draw up a treatment plan with such
a specialist.

ATыбор плана лечения зависит от типа лейкоза, возраста пациента,
the presence of abnormal leukocytes in the cerebrospinal fluid, and
also from previous treatment.

Treatment methods

The main treatments for leukemia include:

  • Chemotherapy
  • Biological treatment
  • Radiation therapy
  • Bone marrow transplantation (stem cells)

If the disease is diagnosed in advanced stages, and
the patient has an enlarged spleen, an additional method
treatment is the removal of the spleen.

Treatment больных острым лейкозом необходимо начинать
immediately. The goal of therapy is to achieve remission. AT последующем,
after the disappearance of the clinical manifestations of the disease, the patient
continues to receive prophylactic treatment. This is called
supportive therapy.

Patients with asymptomatic chronic leukemia may not need
immediate treatment. Such patients are prescribed observation and
careful monitoring of the condition. Treatment начинают при появлении или
ухудшении симптомов diseases.

AT настоящее время проводится ряд крупных клинических
research on the use of new methods and drugs for the treatment of
leukemia At the request of the patient, he can take part in
research. For more information, consult
with the attending physician.

AT дополнение к основному курсу пациенту может понадобиться прием
analgesics and other symptomatic treatment to combat
manifestations of the disease, side effects of chemotherapy or
normalization of the emotional state.

Side effects of treatment

Chemotherapy A side effect of chemotherapy is damage to:

  • Клеток blood. The result is an increase in the frequency of infectious
    diseases, bleeding, anemia;
  • ATолосяных фолликулов. Chemotherapy часто приводит к облысению.

Radiotherapy The consequences of radiotherapy are: feeling tired,
redness, dry skin.
Stem cell transplantation The most severe complication is the reaction

donor stem cells. It manifests itself sharp
irreversible damage to various organs, including the liver, skin
and gastrointestinal tract. The effectiveness of the treatment of this
state does not exceed 10-15%.

The remaining effects depend on the area of ​​exposure.

Maintenance therapy

Both leukemia itself and its treatment can cause various
serious health problems. To control these manifestations and
improve the quality of life of patients appointed supportive
therapy. It includes the use of:

  • Antibacterial drugs
  • Antianemic treatment
  • Blood transfusions
  • Dental treatment
  • Special nutrition


AT целом, пятилетняя выживаемость увеличилась в четыре раза по
compared with the figures of 1960 (from 14% to 59.2%). Five year old
Leukemic survival is:

  • Acute lymphoblastic leukemia – 68.8%
  • Chronic lymphoblastic leukemia – 83.1%
  • Acute myeloblastic leukemia – 24.9%
  • Chronic myeloblastic leukemia – 58.6%

Five year old выживаемость детей с острым лимфобластным лейкозом
is over 85% and continues to rise every year. Now
It is believed that children who have had leukemia and have achieved recovery,
have a positive prognosis, since the probability of a relapse is
the type of cancer after such a period of time approaches zero.

Five year old выживаемость детей с острым миелобластным лейкозом
also continues to rise gradually, and at the moment
makes 60-70%.

Survival rates of patients with chronic leukemia less
reliable, as some patients live with such a diagnosis in
for a long time. Five year old выживаемость при данном

There are currently no reliable data to support this.
