Symptoms and treatment of leukemia in children

Children can develop leukemia, a type of cancer that affects the bone marrow and blood. Parents and other caregivers must be aware of the signs and treatments for leukemia because delayed diagnosis can have a major impact on prognosis.

Leukemia in children can cause a variety of symptoms, such as recurrent infections, inexplicable bruises, and chronic exhaustion. These symptoms are frequently confused with those of other illnesses, so it’s critical to exercise caution and consult a doctor if any strange symptoms continue.

Leukemia is usually treated with a combination of radiation, chemotherapy, and occasionally bone marrow transplants. The course of treatment for each child is customized based on their unique requirements and the type of leukemia they have. Families can deal with this difficult period with hope and support by collaborating closely with healthcare providers.

What is it?

A neoplasm that develops in the hematopoietic system is childhood leukemia. These illnesses carry a high risk of harm. A few of them are lethal. Worldwide, researchers carry out countless experiments and create novel medications every day that enable the treatment of these illnesses.

Leukemia causes diseased cells to replace healthy ones in the body. In the end, this causes the baby’s proper hematopoiesis to be violated. Pediatric oncologists treat these diseases because they are cancerous conditions. A child diagnosed with leukemia typically spends his entire life under observation in an oncology center.

Every year, more and more new cases of the disease are registered. Scientists note with regret the fact that the incidence of various forms of leukemia in children increases several times every year. Usually, the first signs of the disease are detected in children aged 1.5 to 5 years. Not only children, but also adults can get sick. For them, the peak incidence occurs at the age of 30-40 years. Some medical specialists call leukemia "leukemia". In translation, this means a new formation of blood. In some ways, this interpretation of the disease is correct. With leukemia, the production of healthy cells of the hematopoietic system is disrupted. Atypical cells appear that are unable to perform their basic functions.

The body cannot control the formation of "poor -quality" cellular elements. They are formed independently. It is often quite difficult to influence this process from the outside. This disease is characterized by the appearance of numerous immature cells that are in the bone marrow. This organ is responsible for hematopoiesis in the body. The name "leukemia" was proposed by Ellerman at the beginning of the 20th century. Later, numerous scientific studies appeared that gave an interpretation of the disease taking into account the impaired physiology. Every year, large financial resources are allocated throughout the world to search for drugs that would save children with leukemia. It must be said that there are significant positive developments in this area. Of all types of leukemia in children, the acute form is most common. This is a classic version of the disease. According to statistics, in the structure of oncological morbidity with leukemia, every tenth is a child. Currently, scientists around the world emphasize the importance of studying and searching for new drugs for leukemia. This is due to the high mortality rate and the increase in the incidence of blood tumors in children.

Causes of occurrence

Today, there is no single factor that contributes to the development of this dangerous disease in children. Scientists put forward only new theories explaining the causes of the disease. For example, they have proven that exposure to ionizing radiation can lead to the development of blood tumors. It has a detrimental effect on the hematopoietic organs. The relationship between exposure to radiation and radiation can also be proven historically. In Japan, after the largest explosion in Hiroshima and Nagasaki, the incidence of leukemia in children increased several times. Japanese doctors believed that it exceeded the average statistical values ​​by more than 10 times! There are also scientific versions that leukemia develops after exposure to chemically hazardous substances. Researchers have proven this fact by modeling the occurrence of the disease in the laboratory in experimental animals. Scientists note that exposure to certain hydrocarbons, aromatic amines, nitrogen compounds, and insecticides contributes to the development of blood tumors. Currently, there is also information that various endogenous substances are capable of causing leukemia. These include: sex hormones and steroids, some tryptophan metabolism products, and others.

For a long time, there has been a viral theory in the scientific world. According to this version, many oncogenic viruses are genetically embedded in the body. However, with adequate functioning of the immune system and the absence of external factors, they are in a passive or non-working state. The impact of various causal factors, including radiation and chemicals, contributes to the transition of these oncogenic viruses to an active state. This viral theory was proposed in 1970 by Hubner. However, not all doctors and scientists share the opinion that oncogenic viruses initially exist in the body. They explain this by the fact that in all cases a healthy child cannot become infected from a child with leukemia. Leukemia is not transmitted by airborne droplets or contact. The cause of the disease lies deep within the body. Numerous breakdowns and disruptions in the immune system often lead to the appearance of neoplasms of the hematopoietic organs in children. At the end of the 20th century, several scientists from Philadelphia found that children suffering from leukemia have abnormalities in the genetic apparatus. Some of their chromosomes are somewhat shorter in size than those of healthy peers. This discovery served as a reason for proposing a hereditary theory of the disease. It has been scientifically proven that in families where there are cases of leukemia, the incidence of leukemia is three times more common.

Blood neoplasms are more common in cases of certain congenital developmental anomalies, as demonstrated by European scientists. Therefore, the risk of leukemia rises by more than 20 times in children with Down syndrome. There appears to be no one consensus theory at this time regarding the genesis and, most crucially, the manifestation of blood tumors in children, based on the diversity of these theories. Determining the disease’s etiopathogenesis takes longer.

Types

1. Acute. These clinical forms of the disease are characterized by a complete absence of healthy cells. In this case, specific red blood cells are not formed. Usually, acute leukemia in children has a rather severe course and is characterized by a sad, unfavorable outcome. Adequate and correctly selected therapy can somewhat prolong the life of a child.
2. Chronic. Characterized by the replacement of normal blood cells with white ones. This form has a more favorable prognosis and a less aggressive course. Various schemes for the administration and prescription of drugs are used to normalize the condition.

Blood tumors have various characteristics. Leukemia cannot progress from its acute form to a chronic one. These two illnesses are not related nosologically. In addition, the disease progresses through a number of subsequent phases. Both lymphoblastic and non-lymphoblastic (myeloid) acute leukemias are possible. These clinical forms of pathologies share a number of traits in common.

Acute lymphoblastic variant typically shows symptoms in young children. The age range of 1-2 years is when this type of leukemia peaks in incidence, according to statistics. The illness has an unfavorable prognosis. Pathology typically has a severe course. The initial tumor focus’s appearance in the bone marrow is what distinguishes this clinical form. Subsequently, distinct alterations manifest in the lymph nodes and spleen, and eventually, the illness extends to the nervous system.

The non-lymphoblastic variant affects boys and girls equally frequently. The peak incidence typically happens between the ages of 2-4. marked by the development of a tumor that looks like a myeloid hematopoietic sprout. Tumor growth is typically fairly rapid. Overabundance of cells eventually make their way to the bone marrow, where they cause hematopoiesis disorders.

Acute myeloblastic variant is typified by the proliferating myeloblasts, which are immature cells. Primary alterations take place in the bone marrow. The tumor process gradually takes over the child’s entire body. The illness progresses in a very serious way. Numerous diagnostic tests are necessary in order to identify this clinical variant of the disease. Death results from delayed treatment or from its absence.

The following are the primary indicators of blood tumors:

• Changes in hematopoiesis parameters. The appearance in the tests of atypical and immature cells that are completely absent in a healthy person. Such pathological forms are capable of dividing very quickly and increasing in number in a short period of time. This feature causes rapid growth of the tumor and severity of the disease.
• Anemia. A decrease in the number of red blood cells is a characteristic sign of hematopoietic tumors. A decreased content of red blood cells leads to tissue hypoxia. This condition is characterized by insufficient supply of oxygen and nutrients to all organs and tissues of the body. Oncological tumors are characterized by severe anemia.
• Thrombocytopenia. In this condition, the normal number of platelets decreases. Normally, these blood platelets are responsible for normal blood clotting. With a decrease in this indicator, the child develops numerous hemorrhagic changes, manifested by the appearance of unfavorable symptoms.

Symptoms

The initial symptoms of leukemia are typically extremely subtle. Early on in the illness, the child’s health is essentially unaffected. The infant has a typical life. The disease cannot be "visually" suspected. Leukemia is typically discovered during clinical testing or when it progresses into the active stage.

Initial non-specific symptoms include: appetite loss, extreme exhaustion, trouble sleeping through the night, mild apathy, and slowness. Parents are usually not concerned about these signs. Often, even the most watchful parents are unable to identify the illness in its early stages.

The child eventually exhibits adverse symptoms of the illness. Skin tone fluctuates frequently. It gets dull or takes on an earthy hue. Membranes made of mucous can bleed and erode. This causes gingivitis and stomatitis to appear. Ulcerative-necrotic inflammation of the oral cavity can occur occasionally.

A possible increase in lymph nodes is present. In certain types of leukemia, they show up from the side. The lymph nodes are typically quite tightly fused with the surrounding skin and dense to the touch. Physicians differentiate Mikulicz syndrome. A growth in the salivary and lacrimal glands is the hallmark of this illness. Leukemic infiltration is the cause of this particular syndrome.

Different hemorrhagic syndromes manifest when the total number of platelets in the blood decreases. They may show up in children in a variety of ways. Leg bruises are the most typical manifestation. Usually, they don’t result from falls but instead arise on their own without any traumatic injuries. Children may also experience gum bleeding and nosebleeds. Hemorrhages into the abdominal cavity are the most dangerous type.

A relatively common symptom is the onset of joint and muscle soreness. The emergence of tiny hemorrhages in the joint cavities is the cause of this. A child who has the disease for a long time will eventually develop pathologically excessive bone fragility. Bone tissue becomes loose and is more vulnerable to mechanical impact and other forms of damage.

Internal organ disorders manifest as a result of the disease’s active development. Hepatosplenomegaly, or an enlargement of the liver and spleen, is common in children with leukemia. This symptom is typically easily palpable when the abdomen is examined with an ultrasound.

Heart rhythm abnormalities are associated with the late stages. The main cause of this is acute anemia. Increased heart contractions are the result of insufficient oxygen reaching the heart muscle. This illness typically shows up in children as tachycardia, and in certain cases, as arrhythmia (irregular heart rhythm).

Leukemia patients’ body temperatures do not always fluctuate. It can stay normal throughout the illness in many children. The fever is one of the symptoms of certain clinical forms of leukemia. It typically rises during a leukemic crisis, which is a marked worsening of the illness.

The child’s physiological development is disturbed as a result of the disease’s quick development. Children with leukemia typically do much worse than their classmates on a wide range of health measures. Children with severe illnesses often do not gain weight well because of the lengthy and severe course of the illness. The child suffers greatly as a result of chemotherapy side effects, appetite disorders, and antitumor drug side effects.

Another very common feature of leukemia is a decrease in the leukocyte count. These cells’ normal function is to defend the body against infections. Significant reductions in immunity are a result of leukopenia, or a decrease in leukocytes. Leukemia patients’ children are many times more prone to contract even the most common colds. Children who suffer from severe leukopenia are required to receive treatment in a sterile box.

Diagnostics

Regretfully, early detection of leukemia is not always achievable. Early disease identification should be facilitated by laboratory diagnostic techniques. A child is typically prescribed these tests by a pediatric hematologist or oncologist. Every blood oncological neoplasm is diagnosed by specialists.

If your child exhibits adverse characteristic symptoms, you may be able to suspect the illness at home. If they are found, you should consult a hematologist right away for guidance and further testing. Usually, it takes a few exams to determine the accurate diagnosis.

A standard blood test is the initial screening procedure. This easy-to-read study aids in identifying a drop in platelet and red blood cell counts. Finding abnormal immature blood cells can also provide useful information from a blood smear. A rise in the ESR along with alterations in the quantity of platelets and red blood cells suggests that a baby may have leukemia.

A spinal puncture is the primary test that can be used to precisely identify whether the body contains immature cells. A tiny amount of biological material is removed by the doctor during this procedure in order to examine it. The procedure is intrusive and calls for a specialist with reasonable training. You can precisely identify the stage and morphological type of leukemia as well as its presence with this study.

Highly instructive studies using computed tomography and magnetic resonance imaging are examples of additional diagnostic techniques. They aid in the diagnosis of different tumors. Examinations of the bone marrow enable us to determine all pathological alterations that exist in the hematopoietic organ. An MRI of the abdominal organs can be used to rule out intra-abdominal hemorrhage in more advanced stages of the disease and to detect an enlarged liver and spleen.

Prognosis for the future

Various clinical forms of the disease may progress differently. Numerous factors influence it. Leukemia can sometimes be cured. Everything is dependent on the unique traits of the infant. Children who suffer from several chronic illnesses recover more slowly. Curing leukemia is not always possible. Typically, the prognosis is poor when the disease reaches its later stages.

Children with leukemia have a serious form of cancer that affects the bone marrow and blood. It frequently manifests as fatigue that lasts all day, frequent infections, and mysterious bruises. Parents must recognize symptoms and seek medical attention as soon as possible because early diagnosis and treatment, including chemotherapy and supportive care, can significantly improve outcomes.

Treatment

Leukemia treatment plans are still determined by hematologists or pediatric oncologists. Many treatment plans have currently been created with the intention of extending remission. Hospital settings are used to treat disease relapses. The disease typically progresses in waves. Relapses often follow intervals of total well-being.

Chemotherapeutic medication is the primary treatment for leukemia. The course of treatment can change and is mostly determined by the disease’s clinical manifestation. Different dosages and frequency of use may be prescribed for therapy drugs. Choosing a suitable treatment plan to manage the excess quantity of tumor atypical cells and encourage the growth of healthy ones is a crucial part of the process.

Sometimes immunostimulation is added to polychemotherapy. Such therapy is required to boost immune system function and stimulate the immune system. Furthermore, radical techniques can be used to treat some types of leukemia. These consist of introducing stem cells and transplanting donor bone marrow. Blood transfusions are used to treat severe anemia symptoms.

Kids with leukemia need to eat a lot of calories. Their daily calorie intake typically slightly exceeds averages for their age. A child’s immune system needs to be actively functioning for them to consume such a diet. Without the proper nutrition, babies are weaker and have a harder time enduring chemotherapy.

Symptoms	Treatment
Frequent infections	Chemotherapy to kill cancer cells
Fatigue and weakness	Blood transfusions to restore healthy cells
Pale skin	Bone marrow transplant to replace damaged cells
Easy bruising or bleeding	Radiation therapy to target specific areas
Swollen lymph nodes	Medications to manage symptoms and boost the immune system

Children with leukemia have a dangerous illness that can be very stressful for their families. It’s critical to identify symptoms early on in order to seek medical attention in a timely manner, such as fatigue, recurrent infections, or unusual bruising. The likelihood of a successful course of treatment for leukemia increases with an early diagnosis.

Treatments like radiation, chemotherapy, and occasionally bone marrow transplants offer hope for recovery because of advancements in medical care. To guarantee the best care for their child, families should be well-informed, proactive in their inquiries, and closely collaborate with medical professionals.

Dealing with this journey can be greatly aided by professional counseling and the support of loved ones. Many children with leukemia go on to lead healthy, active lives after treatment, despite the fact that the road may be difficult.
