The classification cent type of leukemia

【Classification 】the classification of leukemia is divided into impatient and chronic two major typeses according to the dividing of cell length of degree, natural course of illness.

Is divided into some types according to the type of cell again.If the impatient leukemia is again divided into impatient and lymphoid cell leukemia and the acute not- lymphoid cell leukemia.The our country according to a FAB of common draw-up in the house of the method, the United States and English Three Kingdoms hematology classification and puts forward a following cent type:

1.General type leukemia

(1)the impatient leukemia lymphoid cell type:①The first(L1);②The second(L2);③The third(L3).Not- lymphoid cell type:①Grain cell leukemia:Don't divide a type(M1);②Grain cell leukemia:The part divides a type(M2);③The grain increases of early take care of the young a grain of cell leukemia(M3);④Grain-unicellular leukemia(M4);⑤The list checks a cell leukemia(M5);⑥Red leukemia(M6);⑦Huge pit cell leukemia.(M, )

(2)the chronic leukemia ① lymphoid cell leukemia;②Grain cell leukemia;③Grain-the list check a cell leukemia;④The list checks a cell leukemia.

2.Special type leukemia

(1)low increase born nature of leukemia;

(2)lymphoid tumor leukemia;

(3)organize cell(net cell) tumor leukemia;

(4)strach a cell leukemia;

(5)many hair cell leukemia;

(6)love a sour grain cell leukemia;

(7)love an alkali grain cell leukemia;

(8)impatient leukemia etc. of difficult cent type.

The pediatric period regards impatient and lymphoid cell leukemia as principle and takes up above 75% of the pediatric leukemia around;The acute not- lymphoid cell leukemia has 20%~25% around;Chronic has 3%~5% or so.

In addition to above-mentioned appearance credit, can also combine the type that the immunology, cell genetics carries on a cent, namely MIC cent type.
