Most cases of chronic granulocytic leukemia are due to abnormal enlargement of the spleen, leading to abdominal distension and poor appetite. A small portion of chronic granulocytic leukemia cases show no obvious symptoms and are only discovered through routine physical examinations, finding an abnormal increase in white blood cells, leading to diagnosis and treatment in the hematology department. Common clinical symptoms of chronic granulocytic leukemia include an enlarged spleen. Additionally, some patients may also experience fatigue due to anemia, and a very few patients seek medical advice due to bleeding caused by a decrease in platelets.

How is leukemia diagnosed?

When a routine blood test suggests the possibility of leukemia, further diagnostic tests such as bone marrow aspiration, biopsy, and immunophenotyping are required to confirm the diagnosis. Leukemia can be divided into acute leukemia and chronic leukemia. Acute leukemia includes acute myeloid leukemia and acute lymphoblastic leukemia. Acute myeloid leukemia is further categorized into eight types, from M0 to M7. Acute lymphoblastic leukemia is divided into three subtypes: L1 to L3. Chronic leukemia can be divided into chronic myeloid leukemia and chronic lymphocytic leukemia.

Does leukemia cause coughing?

Leukemia patients' coughing is not directly caused by the leukemia itself, but often due to pulmonary inflammation that commonly accompanies leukemia, leading to symptoms such as coughing, phlegm, and chest pain. Due to a reduced count of normal neutrophils, leukemia patients have low resistance and poor immunity, making them highly susceptible to secondary infections, particularly pulmonary infections. Following a pulmonary infection, whether bacterial, fungal, or viral, patients may experience symptoms including coughing, severe cases may involve coughing up phlegm, chest pain, and breathing difficulties.

The difference between chronic granulocytic leukemia and leukemia

Leukemia is divided into acute leukemia and chronic leukemia. Acute leukemia is further categorized into acute lymphocytic leukemia and acute myeloid leukemia, while chronic leukemia is divided into chronic lymphocytic leukemia and chronic myeloid leukemia. Chronic myeloid leukemia, also known as chronic granulocytic leukemia, generally has a better prognosis compared to acute leukemia, with a higher cure rate and longer survival. Among these, chronic granulocytic leukemia has targeted treatment drugs such as imatinib and dasatinib.

What is acute leukemia?

Acute leukemia is a malignant clonal disease originating from hematopoietic stem progenitor cells. Normally, hematopoietic stem progenitor cells differentiate into white blood cells, which gradually mature into normal white blood cells. However, leukemia cells are primitive cells and immature cells, which means that the hematopoietic stem cells lose the ability to differentiate and mature. Additionally, they proliferate massively in the bone marrow while suppressing normal hematopoietic functions, and can widely infiltrate various organs such as the liver, spleen, and lymph nodes. Due to the suppression of bone marrow hematopoiesis, patients may exhibit clinical manifestations such as anemia, bleeding, and infections. Patients with acute leukemia often seek medical attention because of fever, fatigue, or bleeding from the skin and mucous membranes.

Chronic granulocytic leukemia etiology

Chronic granulocytic leukemia is a myeloproliferative tumor originating from multipotent stem cells. It is characterized by the translocation of chromosomes 9 and 22 forming the BCR/ABL fusion gene. The Philadelphia chromosome is a characteristic change in chronic granulocytic leukemia, first discovered and named in Philadelphia in 1960. Initially, it was observed as a deletion of the long arm of the primary chromosome in dividing blood cells of patients with this leukemia. Currently, studies have shown that abnormalities in the interaction between hematopoietic progenitor cells and the stroma might be central to treating the disease. Abnormal adhesion and anchoring characteristics of progenitor cells lead to disrupted cell maturation and proliferation. Chronic granulocytic cells do not adhere to stromal cells as normal cells do, particularly lacking integrin-mediated adhesion. Additionally, the expression of the adhesion molecule lymphocyte function-associated antigen 3 is also reduced in these cells. Therefore, the progression of the disease results from clonal changes. During the transformation of chronic granulocytic leukemia to acute myeloid leukemia, there is an increased rate of genetic mutations. Changes in gene expression during the progression involve various aspects, including nucleosome sugar metabolism, bone marrow myeloid differentiation, genomic instability of cell apoptosis genes, and processes related to DNA damage repair.
