CML Flashcards
1
Q
Ph chromosome breakpoints
A
t(9;22) - Philadelphia
p190 - more ALL
p210 - more CML
(alphabetical)
2
Q
CML major molecular response
A
<0.1% BCR-ABL or >3 log reduction
3
Q
CML phases
A
Chronic phase
Accelerated phase: blast 10-30%
Blast phase: blast >30%; 1/3 AML, 2/3 ALL –> HSCT
4
Q
CML TKI options
A
Imatinib
Dasatinib - faster/deeper remission
NIlotinib - faster/deeper remission
Ponatinib (for T315I mutation or TKI resistance)
all have similar OS
5
Q
TKI s/e
A
myelosuppression
fluid retention
rash
hepatotoxicity (transaminases)
endocrinopathies
6
Q
CML HSCT criteria
A
accelerated/blast phase
failure of multiple TKI
unacceptable/intolerable TKI toxicity
