The modern medical science knows leukemia outbreak

(A)Epidemiology

The leukemia builds the blood system malignant disease and fasten growth to divide in the process mature obstacle of build blood cell to wait an organization gram in the marrow, the Long unusually increases to living, and gradually other organizations and dirty machine, normally build blood is repress, produce from here anemic, bleed, infection, the liver Pi be lymphoid to knot swollen greatly the etc. a series of symptom body advertise for.

The leukemia is one of the main diseases which causes the malignant tumor die, among them, the impatient leukemia have the tumor death of adult under 35 years of age first.According to the covariance, in the outbreak rate the tallest Western Europe, white man in North America leukemia death rate is 3.2~7.4/10;The outbreak rate low Asia, year death rate in South America is 2.8~4.5/10.(the ＡＯｋｉ etc., 1982)Year outbreak rate and death rate of our country for 2~4/10.(Chu3 Jian4 lately, 1978)From total up see a male outbreak rate the Gao is at the female, about 1.3:1.The leukemia can take place to after any age, the age of total outbreak rate distributing curve to present two high peaks, baby's infancy appearing the first high peak, descending later on, 20 years oldly start rise, go to an old age period to attain the second high peak, empress a phenomenon probably with deliver sex marrow lump, chronic and lymphoid cell leukemia more, after hair leukemia etc. with age the growth increases gradually relevant.The our country leukemia type distribute impatient many in chronic, about 3.8:1, much see by Sui cell leukemia, wait the type of country with Europe and America to distribute more and obviously difference.

(Two)The cause of disease learn

The accurate cause of disease of mankind's leukemia up to now don't be clear and many factor is think to relate to be taken bad of leukemia.The virus may be a main factor and in addition still have a heredity factor, project, chemistry poison or medicine factor.

1.the virus be main with the result that cause of disease vegetable, the lymphoid cell leukemia virus Ⅰ type(HTLV-1) of mankind Ｔ contains contagion and induct an adult T cell the leukemia has already been confirm.

2.the heredity factor relate to some leukemia outbreakses and have data enunciation a leukemia a sufferer a family the leukemia outbreak in the member a rate to increase Gao.

3.project a factor electricity to leave radiation and leukemia to relate to closely, the size of its function and radiation quantity has relation with part.Have already known that the certain Ｙ for measure shoots line and can induct a leukemia now.Such as in 1945 after Japanese wide island, atomic bomb in Nagasaki explode, the luckily survive leukemia outbreak rate presents few decuples ascension.Still have no enough proof to express that the general emanation amount of for Ｘ line to diagnosis can cause a leukemia currently.

4.the contact benzene, methyl benzene, chlorine ethylene...etc. of the chemistry factor occupation and the outbreak of leukemia contain certain relation.Cause with the anti- tumor medicine(mainly is an alkane to turn a , A Ji Xia Pian, second nitric Ji gland etc.) in the chemistry medicine the report way of leukemia gradually increases.B double the Mao may also inducts a leukemia, other like chloromycetin, protect Tai loose, the Huang An increase an effect and sleep well a town quiet medicine, melting agent, insecticide...etc., drive all Yi for may induct a leukemia. 5.other factors such as chronic germ sexy dye, fungi infection, the abnormal condition respond, external injury, bone fracture etc., but all lack an accurate proof.The machine body immunity function's ising lowly is also the important inducement of outbreak in the meantime.

(Three)Pathology

The leukemia can learn according to the course of illness, clinical characteristic and the cell appearance etc. carry on a classification.

1.the course of illness categorizes with clinical characteristic

Press the course of illness slowly nasty can is divided into a leukemia with the mature degree of the leukemia cell:(1)Impatient leukemia:Condition development quick, marrow and surroundings blood in mainly is abnormality originality and immature cell;(2)Chronic leukemia:The course of illness is slower, mainly is more mature excrescent cell in marrow and blood, secondly is an immature cell.The chronic leukemia can also press the different cell series and is divided into a chronic grain a cell leukemia(call a slow grain), chronic and lymphoid cell leukemia(the brief name slowly pours), many hair cell leukemia with young lymphoid cell leukemia.

2.the cell appearance learn a classification

Can is divided into(1) an impatient and lymphoid cell leukemia;(the brief name be nasty to pour)(2)The acute not- lymphoid cell leukemia.(brief name's being nasty don't pour)The latter mainly includes an impatient grain cell leukemia(call a nasty grain) and impatient list to check a cell leukemia.(call nasty list)

3.press the outside week the white cell total amount and the immature cell amount in the blood elephant can is divided into:(1)The white cell increases sex:The outside week white cell in blood shows Zhao to increase(15 ×s 109/L be above), also in great quantities immature cell;(2)The white cell doesn't increase sex:The outside week white cell in blood doesn't increase, even low in normal(15 the × ＩＯ 9/L the following), more difficult detection unusually immature cell in blood.

4.special type leukemia

(1)low increase a born nature leukemia;(2)The cell tumor of green lump or grain;(3)Love a sour grain a cell leukemia;(4)Love an alkali grain a cell leukemia;(5)Fatty and big cell(or the organization love alkali cell) leukemia;(6)Adult T cell leukemia;(7)The non- Ｈｏｄ gram ｋｉｎ lymphoid lump cell leukemia;(8)Strach a cell leukemia;(9)Impatient mixture cell leukemia;(10)Impatient whole Sui cell leukemia.
