Acute leukemia is first divided into two main categories: one is acute myeloid leukemia, and the other is acute lymphoblastic leukemia. The chemotherapy regimens for these two types are different. Among them, acute myeloid leukemia is further divided into eight types from M0 to M7, among which type M3 can be treated with oral targeted chemotherapy drugs, while other types of acute myeloid leukemia require chemotherapy for treatment. The other main category is acute lymphoblastic leukemia, which also requires chemotherapy for treatment.

chronic granulocytic leukemia platelets

Patients with chronic granulocytic leukemia have variations in blood platelets as seen in routine blood tests, which differ according to different stages of the disease. In the chronic phase, especially early on, platelet counts are mostly elevated or normal, with increases potentially exceeding 1000x10^9 per liter. The shape of the platelets is normal, but their function is often abnormal, with thrombus formation being rare. A minority of patients may experience a decrease in platelet count. As the disease progresses, routine blood tests can reveal significant decreases or increases in platelet counts along with the appearance of megakaryocytes. Additionally, some patients may also exhibit bone marrow fibrosis, characterized by an increase in reticular fibers or collagen fibers.

Is leukemia treatment free?

Leukemia is a type of malignant tumor originating from hematopoietic stem cells and progenitor cells in the myeloid hematopoietic system. Leukemia cells differentiate and organize at the early stages of different myeloid developments, exhibiting the morphological and immunophenotypic characteristics of myeloid development. The incidence of acute myeloid leukemia in the population is 2-4/100,000, with the median age of onset being sixty-four to seventy years, making it a disease of the elderly. The incidence increases with age, accounting for 70% of acute leukemias, and representing 55%-70% of infant, 17%-20% of childhood, and 80%-90% of adult acute leukemias. Regarding the medical insurance situation in China, some leukemia conditions are eligible for major illness assistance. All leukemia treatments can be reimbursed at a certain ratio under the national health insurance, although there is no free treatment for leukemia at present, unless one participates in relevant clinical trials, which could offer some compensation, and certain treatment drugs are provided free of charge.

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 course

The course of chronic granulocytic leukemia is relatively long, as it is a type of chronic leukemia. Its onset is gradual, and its natural course includes four stages: asymptomatic phase, chronic phase, accelerated phase, and blast crisis phase. Most patients seek medical attention and are diagnosed only after symptoms appear, with very few patients discovering blood abnormalities during physical examinations or blood tests conducted for other reasons. At this point, the spleen may already be mildly enlarged, or not enlarged at all. In the early stages of the disease, some patients may experience an absolute increase in basophilic granulocytes. When the white blood cell count is less than 20×10^9/L, there is a decrease in neutrophil alkaline phosphatase activity in peripheral blood, and this decreases further as the disease progresses. When the white blood cell count exceeds 40×10^9/L, the spleen can be felt below the ribs. Between 30 and 90×10^9/L, a range of related clinical symptoms may appear.

The difference between chronic granulocytic leukemia and leukemia.

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.
