Patients with leukemia need to be further classified to determine if it is acute leukemia or chronic leukemia, whether it is acute myeloid leukemia or acute lymphoblastic leukemia in the case of acute leukemia, and whether it is chronic myeloid leukemia or chronic lymphocytic leukemia in the case of chronic leukemia. Therefore, in addition to routine blood tests, leukemia patients also need to undergo bone marrow cytology, immunophenotyping, testing for 43 types of leukemia fusion genes, chromosome tests, etc., to further clarify the subtype of leukemia. After the subtype is clarified, a treatment plan is selected based on the specific type.

Is chronic myeloid leukemia scary?

Chronic myeloid leukemia, though a type of leukemia, is not terrifying because there are targeted drugs available for it, namely tyrosine kinase inhibitors. These inhibitors have been developed into first, second, and third-generation products. Most cases of chronic granulocytic leukemia can achieve clinical remission after oral administration of tyrosine kinase inhibitors. Some patients might experience a blast crisis, acceleration phase, or relapse during treatment, but they can switch to higher-grade tyrosine kinase inhibitors or undergo allogeneic hematopoietic stem cell transplantation. Thus, chronic myeloid leukemia is no longer considered a frightening disease. (Please use medication under the guidance of a doctor.)

Early symptoms of childhood leukemia

Generally speaking, leukemia can manifest symptoms related to a decrease in all three blood cell lines. Changes in these three lines typically include an increase or decrease in white blood cells, a decrease in red blood cells leading to symptoms of anemia, and a reduction in platelets, resulting in symptoms of bleeding. Children with leukemia often experience recurrent fevers and are prone to infections, as well as bleeding gums. There may also be enlargement of the liver, spleen, and lymph nodes, along with pallor of the face and lips, which appear pale and bloodless.

Symptoms of leukemia

The symptoms of leukemia can be categorized into four main types: infections, anemia, bleeding, and organ infiltration. Infections occur due to a decrease in neutrophils, leading to poor resistance of the body and can trigger infections in various parts, such as lung infections, gastrointestinal infections, urinary system infections, etc. Anemia is caused by the growth of leukemia cells, which leads to limited erythropoiesis in the bone marrow, resulting in symptoms such as dizziness, headache, fatigue, poor appetite, and decreased tolerance to activity. Bleeding is due to a significant reduction in platelets in leukemia patients, making spontaneous bleeding more likely, which can manifest as bleeding from the skin and mucous membranes, organ bleeding, etc. Tumor infiltration can lead to abnormalities in other organs.

The Difference Between Acute Leukemia and Chronic Leukemia

The difference between acute and chronic leukemia lies in the maturity stage of the leukemia cells. Acute leukemia is characterized by more immature leukemia cells, while chronic leukemia cells tend to be more mature. Acute leukemia is further divided into acute myeloid leukemia and acute lymphoblastic leukemia. Among them, acute myeloid leukemia is subdivided into eight types, from M0 to M7. Chronic leukemia is divided into two main categories: chronic lymphocytic leukemia and chronic myeloid leukemia. As the name suggests, acute leukemia has a rapid onset and a shorter survival period, whereas chronic leukemia develops more slowly and has a longer life expectancy.
