Term
what are the 4 types of AML?
Definition
1. genetic aberrations 2. MDS-like 3. therapy-related 4. NOS
Term
what are the 4 types of genetic aberrations?
Definition
t(8;21), inv(16), t(15;17), t(11q23)
Term
what are the 2 drug categories that cause therapy-related AML?
Definition
topoisomerase II inhbitors (etoposide, tenoposide) and alkylating agents
Term
alkylating agents usually cause what cytogenetic defect that would lead to AML?
Definition
deletion of chromosome 5 or 7
Term
topoisomerase II inhibitors usually cause what cytogenetic defect that would lead to AML?
Definition
MLL mutation
Term
what is the single diagnostic criteria for AML?
Definition
>20% myeloblasts in bone marrow
Term
general tx strategy for AML
Definition
RTK inhibitors to block proliferation + histone deacetylase inhibitors to allow maturation
Term
t(8;21) protein
Definition
ETO/AML1
Term
t(8;21) prognosis
Definition
good with chemotherapy and in absence of cKIT mutations
Term
inv(16) protein

RAR-alpha/PML
Term
pt presents with high WBC, and high risk of DIC; what genetic mutation do you suspect?
Definition
t(15;17)
Term
pt presents with low WBC and reniform nuclei; which AML is this?
Definition
hypergranular variant of t(15;17)
Term
cytogenetic analysis shows a FLT3 mutation; what fusion protein do you suspect you will find and what is the translocation?
Definition
RAR-alpha/PML; t(15;17)
Term
tx for t(15;17) AML
Definition
ATRA
Term
t(11q23;v) protein
Definition
MLL fusion genes
Term
peripheral blood smear shows blasts of myeloid and monocytic series but no eosinophils; what translocation do you suspect?
Definition
t(11q23;v)
Term
pt is positive for MLL fusion genes; what complications are you worried about if the pt's WBC count is low?
Definition
thrombus formation

hypogranular t(15;17) complication
Definition
DIC
Term
Auer rods; general dx?
Definition
AML
Term
what genetic defect do topoisomerase II inhibitors cause to induce AML?

myeloid and monocytic blasts + eosinophils on peripheral blood smear; dx? translocation?
Definition
AML; inv(16)
Term
tx: ATRA; dx? translocation?
Definition
AML; t(15;17)
Term
peripheral blood smear shows Auer rods, reniform nuclei; high WBC count; what complication is most likely to be involved?
Definition
DIC
Term
fluorescent staining for CBF-beta shows it sequestered in the cytoplasm of blast cells; what is the genetic mutation? what is the fusion protein?
