How is the leukemia to divide a type?
Familiar have a lot of article reports of the leukemia of way various type, so how is the leukemia to divide a type? 1.according to condition nasty the mitigation leukemia cell mature degree can is divided into an impatient and chronic leukemia.The impatient leukemia rises a disease nasty, the course of illness is short, in marrow and surrounding blood with abnormality of the originality early expect immature cell is lord, original cell often more than 30%.In the chronic leukemia course of illness slow-moving, marrow and surroundings blood with abnormality mature of white cell is lord, the companion contains immature cell.Original cell generally not more than 10%~15%. 2.can is divided into 2 types: lymphoid cell and grain cell leukemia according to increasing the type of livinging the cell.Combine nasty mitigation cell of condition type, the leukemia is total of can is divided into 4 kinds of basic types:①Impatient and lymphoid cell leukemia(acute lymphocytic leukemia, ALL), ② chronic and lymphoid cell leukemia(chronic lymphocytic leukemia, CLL), ③ impatient grain cell leukemia(acute myelocytic leukemia, AML) or acute not- lymphoid cell leukemia(acute non-lymphocytic leukemia, ANLL), ④ chronic grain cell leukemia.(chronic myelocytic leukemia, CML) The clinical performance, blood of impatient leukemia and chronic leukemia is like, the marrow be like and cure none of principles same.The impatient leukemia can get into to alleviate a period after treatment, generally don’t change into chronic.The chronic leukemia expects to often have acute to change behind, clinical express very the elephant impatient leukemia. 3.can is divided into according to the amount of white cell inside the surroundings blood white cell’s increasing sex leukemia(the surrounding white cell amount inside the blood increases, >15000| μs 1) and white cell don’t increase sex leukemia.(the surrounding white cell amount inside the blood doesn’t increase, even decrease) 4.the immunology classification of leukemia applied single gram of Long antibody and molecular biology technique examine the immunity marking of leukemia cell to discriminate the source of leukemia cell, such as the impatient and lymphoid cell leukemia can is divided into a T cell type, B cell type, front-B cell type and have no marking cell type etc.. In majority of of our regions, the impatient leukemia compares a chronic leukemia to much see.Whether the impatient or chronic leukemia all shares majority by grain cell or not, impatient and lymphoid cell leukemia time, the chronic and lymphoid cell leukemia at least sees.The impatient leukemia is seen to the child and the teenager more, chronic grain cell the leukemia be much seen to 30~50 years old.The chronic and lymphoid cell leukemia much takes place at 50 years old above.The leukemias of various type are all more to be seen to a male.
