De acute leukemieën
Kenmerken
- Plots opkomend
- Zeer ernstig
- Niet voor lange tijd
- Blasten die te veel woekeren
- Afwijking WBC

Methoden in de Hematologie
- Microscopie + cytochemie
- Immuunfenotypering: flow cytometrie
- Cytogenetica
- Moleculaire testen

Casus 1
- Blasten +++ in BM: Vanaf 20% = acute leukemie
- CD merkers aanwezig van myeloïde reeks: CD45/CD33/CD13/CD34
- Abnormaal karyotype: chromosoom te veel

Cytogenetica
1. Conventionele karyotypering
Methode


- Heparine toegevoegd: werking anti-
trombine 3 bevorderen
- Toevoegen antibiotica: besmetting
+ heparine tegengaan
- Colchicine = spoelgift: blokkeert
cellen in metafase
- Hypotone zoutoplossing: cellen
zwellen (beter bekijken)
RPMI
- Giemsa kleuring: kleurt A(denine) –
T(hymine) rijke gebieden donker
FCS
- Chromosomen rangschikken van (1)
L-glutamine
groot naar (22) klein 
streptomycine chromosomenkaart
penicilline

, Voordelen
- Screening volledig genoom
- Detectie chromosomale afwijkingen zonder moleculair target
- Detectie nieuwe moleculaire targets
- Gemakkelijk te zien bij acute leukemie

Nadelen
- Lage resolutie: er moet al grote afwijking zijn om te kunnen waarnemen
- Metafasen nodig
- Lage sensitiviteit
- Expertise
- Tijdrovend: duurt paar weken
- Moeilijk voor chronische leukemie

Chromosomenkaart
- Translocatie: stuk
chromosoom 22 naar 9
- Deletie: tekort chromosoom
x = geslachtschromosoom
- Monosomie: 1 aanwezig bij 7
- Mar = resten
