What are the types of leukemia?

1. What is leukemia?

Leukemia is a malignant tumor of the hematopoietic system, also known as blood cancer. It is characterized by extensive naïve leukocyte proliferation in the bone marrow and other hematopoietic tissues, and can invade and destroy other tissues. Two:

Types of leukemia.

According to the course of the disease, the cell type and the characteristics of the surrounding blood picture, leukemia can be classified as follows: 1) according to the severity of the disease course and the maturity of leukemia cells

Acute type, acute onset, short course of disease, without special **, the general course of the disease does not exceed 6 months. The blasts in the bone marrow are markedly increased at more than 10, and there may be naïve cells in the surrounding blood. ②

Chronic type, slow onset, long course of disease, without special ** course of disease is generally more than one year. The bone marrow is like less than 2 blasts, and naïve and mature cells are the majority. (2) According to the abnormal proliferation of different white blood cell series, it can be divided into:

Acute lymphoblastic leukemia can be divided into three types according to cell morphology: type 1 (L1), which has a better remission rate after cell differentiation**, and type 2 (L2), which is relatively poor; Type 3 (L3), also known as Burkitt, has very low post-remission. ②

Acute non-lymphoid leukemia (referred to as acute non-lymphoid leukemia) can be divided into: myeloid leukemia, undifferentiated (M1, acute myelomyelopathy); Partial typing of myeloid leukemia (M2, acute granulomy); promyelocytic leukemia with increased granules (M3, promyelocytic); granulomonocytic leukemia, (M4); monocytic leukemia (M5, acute monolith); erythemia (M6); Subacute myeloid leukemia (M7, subacute granule). ③

Chronic leukemia, which can be divided into: lymphocyte (chronic lymph); granulocytes (slow granules); granulocytes; Monocyte; Erythemia. ④

Special types of leukemia can be divided into: slow granular abrupt change; hypoproliferative; Lymphosarcoma; Histiocytic sarcoma; plasma cells; hairy cells; eosinophils; basophils; histobasophils; megakaryocytes; Undifferentiated acute leukemia. 3) Classification according to the number of leukocytes in the surrounding blood:

It can be divided into leukocytosis, in which the number of blood cells in the surrounding blood is in liters (15000 cubic millimeters) and a large number of naïve cells appear. ②

Leukocytosis is not proliferated, the leukocytes in the surrounding blood are below liters (15000 cubic millimeters), and there are only a few naïve leukocytes in the classification, which is called subleukemia; or without naïve cells, called non-leukemia. Leukemia is a common malignant tumor, and China has listed it as one of the top ten malignant tumors for key prevention and treatment. Leukemia accounts for about 5% of the total incidence of malignant tumors, mostly in children and adolescents.

In China, the mortality rate of malignant tumors in all age groups ranks sixth (male) and eighth (female), and it ranks first among children and people under 35 years old.

According to the standard of leukemia classification and classification scheme in China formulated by the National Leukemia Classification and Classification Conference in December 1980.

1. Acute: 1Lymphocytic leukemia: acute lymphocytic leukemia type L1, L2, L3.

2.Non-lymphocytic leukemia:

M1: Acute myeloid leukemia, undifferentiated.

M2: acute myeloid leukemia, partially differentiated.

M3: Acute promyelocytic leukemia, granularity.

M4: acute myelomonocytic leukemia.

M5: Acute monocytic leukemia.

M6: Acute erythroleukemia.

M7: subacute myeloid leukemia.

2. Chronic: 1) Chronic lymphocytic leukemia call

2) Chronic myeloid leukemia CAML

3) Chronic myelomyelomyelocytic leukemia cmml

3. Special Types:

There are chronic myelopathy, hypoproliferative acute leukemia, lymphosarcoma leukemia, histiocytic sarcoma leukemia, plasma cell leukemia, hairy cell leukemia, eosinophilic leukemia, basophilic leukemia, megakaryocytic leukemia and acute stem cell leukemia.

Hello, leukemia is mainly divided into two categories: acute leukemia and chronic leukemia in terms of the progression of the disease and the degree of cell differentiation. There are many different subtypes of acute and chronic leukemia, the common ones are mainly the following categories, acute leukemia is divided into acute myeloid leukemia and acute lymphoblastic leukemia, and acute myeloid leukemia is divided into M0, M1, M2, M3, M4, M5, M6, M7; Chronic leukemia is also mainly divided into chronic myeloid leukemia and chronic lymphocytic leukemia.

There are two categories: chronic and acute.

Chronic division: Chronic lymphocytic leukemia and chronic myeloid leukemia Acute division: acute lymphoblastic leukemia (referred to as acute lymph) and acute myeloid leukemia (also known as acute myeloid leukemia, referred to as acute myeloid leukemia).

Acute shower is divided into: acute shower B and acute shower T, and there are also L1, L2, L3 acute myeloid types: M0-M7, and some subtypes, such as: M2A, M3V, M4EO, M5B, etc.

There is also acute mixed leukemia (characterized by both acute and acute medullary features.

Leukemia is mainly divided into acute leukemia and chronic leukemia. Acute leukemia can be further divided into acute myeloid leukemia and acute lymphoblastic leukemia; Chronic leukemia can be further divided into chronic myeloid leukemia and chronic lymphocytic leukemia. Acute leukemia is a dangerous condition that requires chemotherapy and bone marrow transplantation, while chronic leukemia has a longer course and can be treated with oral targeted drugs**.

Therefore, the overall survival time of chronic leukemia is much better than that of acute leukemia.

Leukemia is morphologically divided into two categories, one is acute lymphoblastic leukemia and the other is acute myeloid leukemia. Acute lymphoblastic leukemia is divided into L1, L2, and L3 types according to cell size; Immunologically, it is divided into acute T-cell leukemia and acute B-cell leukemia; Acute myeloid leukemia is classified into M0-M7, M0 cell is very poorly differentiated, that is, myelocyte microdifferentiation, M1 is myelocytic leukemia, M2 is relatively well-differentiated promyelocyte, that is, myelocytic leukemia partially differentiated, M3 is promyelocytic leukemia, M4 is granulocytic leukemia, M5 is monocytic leukemia, M6 is erythrocytic leukemia, and M7 is acute megakaryocytic leukemia.

Acute leukemia.

Chronic leukemia.

Introduction: When teenagers learn biology, they will have a corresponding understanding of leukemia, because it is very harmful. Generally speaking, if you don't have the best of the best, then it may lead to the loss of your life at a young age, and you need to undergo chemotherapy many times.

It will make your hair fall out, and it may also make your body weaker and weaker, and at this time, you need strong willpower to ensure that you can survive in the process. So what are the types of leukemia? I hope to help those suffering from leukemia and serve as a warning to healthy people.

How much do you know about acute myeloid leukemia? It is mainly due to the appearance of a lot of white blood cells in one's bone marrow, which then leads to more malignant conditions. From the point of view of **, it may be more difficult because of the need for strong chemotherapy techniques and willpower to be able to stop.

This is also a great challenge for the patients themselves, such as those leukemias in the broad sense are generally acute.

Acute lymphoblastic leukemia If it is acute lymphoblastic leukemia, then it is possible that your lymphocytes have lesions, and then the leukemia situation is aggravated, and it is acute at this time. Then you need to cooperate in the hospital in time, so as to ensure that you can return to a normal and normal state in your future life, which is also a very big challenge for yourself.

Maintain a good attitude in the process of inhibition needs to maintain a good attitude, now so that you can face some of the more painful **, so that you can face chemotherapy with more energy. Because it is a test of people's willpower, because at this time, if you find that your hair is falling out, you will have a lot of impatience in your heart.

There are two types, acute and chronic leukemia, and the differentiation of acute leukemia cells is stalled in the early stage, mainly concentrated in primitive and immature cells. The disease progresses rapidly over a few months. Chronic leukemia cells are well-differentiated and are mainly immature or mature cells that develop slowly over several years.

According to the pathological cell series, it includes granulosa cells, monocytes, erythrocytes, megakaryocytes, and lymphoid T and B cell lines. Leukemia is often divided into lymphocytic leukemia, granulocytic leukemia, mixed cell leukemia, etc.

Leukemia is generally divided into two types, namely acute leukemia and chronic leukemia, and there are also very obvious signs in the early stage.

Chronic leukemia, acute leukemia, acute T-cell leukemia, acute B-cell leukemia, acute myeloid leukemia, mature leukemia, red leukemia, acute megakaryocytic leukemia These are all types of leukemia and are very dangerous.

There are two main categories, one is chronic leukemia and the other is acute leukemia, and these two categories contain many other sub-categories.

1. Acute leukemia: abbreviated as AL in English, cell differentiation is stagnant at an earlier stage, mostly blasts and early naïve cells, the disease develops rapidly, and the natural course of the disease is only a few months. Secondly, according to the main affected cells, it can be divided into acute lymphoblastic leukemia (ALL) and acute myeloid leukemia (AML).

1) Acute lymphoblastic leukemia (ALL): It is more common in children under 9 years old, and 20% of the original lymphocytes can be seen in the bone marrow cell examination.

2) Acute myeloid leukemia (AML): It is more common in people aged 15-39 years, and a large number of naïve granulocytes can be seen in the bone marrow.

2. Chronic leukemia: English abbreviation CL, cell differentiation is stagnant at a later stage, mostly more mature naïve cells and mature cells, the disease develops slowly, and the natural course of the disease is several years.

1) Chronic myeloid leukemia (CML): leukocytes are elevated in the blood routine, and moderately mature granulocytes are mainly in the bone marrow examination.

2) Chronic lymphocytic leukemia (CLL): The tumor cells are monoclonal B lymphocytes with morphology similar to normal mature small lymphocytes.

3) Hairy cell leukemia: It is more common in elderly men, and hair cells can be detected on peripheral blood and bone marrow smears.

4) Prolymphocytic leukemia: common in middle-aged and elderly people, generally over 50 years old, and predominantly lymphocytes in the bone marrow.
