Chronic granulocytic leukemia is a myeloproliferative tumor originating from pluripotent stem cells, characterized by the presence of the Philadelphia chromosome or changes in the BCR/ABL fusion gene. Chronic granulocytic leukemia progresses through four stages: asymptomatic, chronic, accelerated, and blast crisis phases. Most patients are diagnosed after the onset of symptoms. Only a very few patients are diagnosed through routine physical examinations or other reasons when blood abnormalities are discovered. The earliest symptoms experienced during the chronic phase of the illness typically include fatigue, dizziness, and abdominal discomfort. The accelerated phase is a transitional stage before the blast crisis, marking a turning point where the disease worsens. It is often difficult to distinctly separate the accelerated phase from the blast crisis, and about 20%-25% of patients may enter the blast crisis phase directly without passing through the accelerated phase.

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 Acute Leukemia

The common symptoms of acute leukemia include four main categories: infection, anemia, bleeding, and tumor infiltration. Symptoms of infection manifest as fever, cough, expectoration, chest pain, abdominal pain, diarrhea, frequent urination, urgent urination, painful urination, skin infections, and perianal infections. Anemia is characterized by dizziness, fatigue, poor appetite, and decreased endurance. Symptoms of reduced platelets mainly involve bleeding, which can manifest as bleeding of the skin and mucous membranes, organ bleeding, and even cerebral hemorrhage. Tumor infiltration can manifest as gingival hyperplasia and skin rashes among other swellings.

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.

Symptoms of Chronic Myelogenous Leukemia

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.
