Chronic granulocytic leukemia is a type of leukemia. Leukemia can be divided into acute leukemia and chronic leukemia. Acute leukemia is further divided into acute myeloid leukemia and acute lymphoblastic leukemia. Among these, acute myeloid leukemia can be divided into eight subtypes from M0 to M7, and acute lymphoblastic leukemia can be divided into three subtypes from L0 to L3. Chronic leukemia is further divided into chronic granulocytic leukemia and chronic lymphocytic leukemia. Therefore, chronic granulocytic leukemia is a subtype of leukemia.

Chronic granulocytic leukemia symptoms

The clinical symptoms of chronic myeloid leukemia can be divided into two phases: 1. During the chronic phase, the earliest subjective symptoms include fatigue, dizziness, and abdominal discomfort. Other symptoms may also appear such as general malaise, decreased endurance, and nausea. Some patients may exhibit signs of increased basal metabolism, such as sweating, weight loss, palpitations, and nervousness. As the disease progresses, patients may experience enlargement of the liver and spleen. An enlarged spleen can cause abdominal bloating, discomfort in the upper left abdomen, and a feeling of fullness after eating. In a few cases, bleeding may occur in the early stages. In female patients, excessive menstruation is common, and while bone pain and joint pain are less common at initial diagnosis, they can also occur. 2. During the accelerated phase, patients often exhibit unexplained low-grade fever, fatigue, lack of appetite, night sweats, and increased weight loss. These symptoms are accompanied by rapid enlargement of the spleen causing discomfort and fullness, sudden swelling of lymph nodes, clear sternal tenderness, and osteolytic changes in bones leading to bone pain. Anemia also progressively worsens. Once patients enter the blast crisis phase, they may show extramedullary infiltration symptoms such as skin nodules, testicular infiltration, abnormal penile erections, and the appearance of green tumors in the eye sockets, among other serious complications.

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.)

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.

Is bleeding gums leukemia?

Gum bleeding is not necessarily leukemia; it could also be gingivitis, periodontitis, or other diseases of the hematopoietic system. Gum bleeding is a common clinical symptom of gingivitis, caused by irritants like dental plaque and tartar around the teeth, keeping the gum tissue in a congested state. If persistent, this can lead to gum bleeding. This condition can be improved by dental cleaning, followed by medicated rinses around the teeth. If the situation does not improve, it may be due to periapical abscess caused by periapical inflammation of the tooth, which can also result in gum bleeding. In this case, root canal treatment is required, and once the inflammation in the root canal is controlled, the gum bleeding may alleviate on its own. If neither of these treatments is effective, it could be due to an underlying hematopoietic system disease, which would require further examination.

What are the symptoms of leukemia?

The symptoms of leukemia mainly fall into four categories: infections, anemia, bleeding, and tumor infiltration. Infections occur because the proliferation of leukemia cells leads to a reduction in the patient's own granulocytes, lowering their resistance and possibly leading to various secondary infections such as respiratory, urinary system, and skin mucous membrane infections. Anemia is due to the proliferation of leukemia cells, which restricts normal erythropoiesis in the bone marrow, leading to symptoms in patients such as dizziness, headaches, fatigue, and decreased stamina. Bleeding occurs due to a decrease in platelets, posing a risk of spontaneous bleeding, which can include bleeding of the skin mucous membranes, organs, and even cerebral hemorrhage. Tumor infiltration by leukemia cells may manifest as tumor masses on the skin surface.
