leukemia Flashcards
chronic myeloid leukemia survual
70%
how common is leukemia
3%
philidelphia chromosome in what disease state
chronic myeloid leukemia
what is the philidelphia chromosome
BcrABL - constitutively active tyrosine kinase oncogene
9 and 22
CML risk factors
atomic bomb
ionizing radiation
is CML familial
no
CML presentation
leukostasis - medical emergency
thick blood
- confusion
- stroke
what is leukostasis
white blood cell count can be in millions
tests we can do to find CML
FISH - fluorescence in situ
PCR - measures pos genes
90% of patients will be in what phase CML
chronic phase
<10% blasts
phases of CML
chronic
accelerated
blast crisis
CML treatment for cure
allogenic hematopoetic stem cell transplant
what is allogenic stem cell transplant
cells from a donor
CML common treatment
tyrosine kinase inhibitors
1st gen: imatinib
2nd gen: nilotinib, dasatinib, bosutinib
3rd gen: ponatinib
T315I: ascitinib, ponatinib
CML treatment monitoring for molecular response done how and with what responses
early BCR-ABL <10% at 3 and 6 month
major: <0.1%
deep: <0.01% - best
imatinib side effect
nausea
dasatinib side effect
fluid retention
pleural effusion
nilotinib side effect
QTC prolongation
metabolic syndrome
bosutinib side effect
diarrhea
ponatinib side effect
HTN
ischemic reactions
vascular occlusion
dasatinib consideration
avoid acid reducers
nilotinib consideration
BID
which drug used for T135I mutation
ponatinib, ascitinib
when can CML patients take a drug holiday
deep molecular response for 2 years (<0.01%)
must be on TKI for 3 years
chronic lymphoid leukemia in who and how common
old white men
more common than CML
CLL risk factors
first degree relative (3 times)
old white men
when do we treat CLL
when we get constiutional symptoms like lymphadenopathy
genetics for CLL linked with worse outcomes
Del 11q
Del 17p
what is Del17p
loss of p53 - worst outcome
Del 17 p happens where
G2 checkpoint
CLL diagnosis
> 5 x 10^9 monoclonal B lymphocytes in peripheral blood
who do we treat in CLL
stage III-IV
symptoms
end organ dysfunction
if pt has super high white count in CLL what do we do
we dont treat a number, they not sick or symptoms
first line CLL if no Del 17p mutation
BTK inhibitors + anti CD20
venetoclax + obinutuzumab
chemo
first line CLL if del 17p
no chemo
BTK + CD20
venetoclax + obinutuzumab
BTK inhibitors
acalabrutinib
zanubrutinib
which BTK not recommended anymore
ibrutinib - lots toxicities like afib
venetoclax class
bcl 2 inhibitor
venetoclax drug interactions
CYP3A4 and PGP
PGP drugs
heart drugs: carvedilol, amio, verapamil
phenytoin / rifampin
carbemazepine
venetoclax side effect/toxicity
tumor lysis syndrome (ramp up dosing)
what can happen when we give BTK inhibitros
peak in white / lymphocyte count
transient lymphocytosis
does not signify disease progression
watch after 3 weeks
transient lymphocytosis occurs with what
BTK inhibitors
AML death rate
poor prognosis
5 yr 30%
AML arises from what
arise from single leukemic cell
AMl risk factors
alkylating agents
topo II inhibitors
most causes unknown
AML presentatiomn
anemia
neutropenia
thrombocytopenia
bone pain
gum hypertrophy
AML diagnosis
> 20% blasts from bone marrow
gentic factor in AML that would be poor prognosis
FTL3-ITD mutation
drugs that target FTL31
midostaurin
quizartinib
how does AML treatment work
induction and consolidation phase
biopsy then induction and remission (counts go back up)
biopsy again to confirm remission or do consolidation
what is consolidation in AML
if favorable: chemo
unfavorabel: stem cell
AML treatment analogy
spray the weeds and flowers, wait to see what grows back
if only flowers - complete remission
if weeds too - need to do something else
induction therapy eligible AML
cytarbaine (7 day) + anthracycline (3 day)
induction therapy ineligible (cant tolerate chemo)
venetoclax + azicitibine
what is 7+ 3
7 days cytarbine
3 days rubicin
cytarabine toxicity
myelosupression
neutropenia
AML consolitadtion treatment
high dose cytarabine
high dose cytarbine side effects
cerebellar toxicities
(check handwriting)
chemical conjunctivitis`
acute promyelocytic leukemia is what gene
10% of AMLs
t(15,17) = PML: RARA
acute promyelocytic leukeia treatment
trans retinoic acid
arsenic trioxide
differentiation syndrome happens from waht
APL treatment
ALL most common leukemia in whatq
children
risk factors for ALL
predisposition gene
EBV
HIV
ALL presentation
anemia
thrombocytopenia
neutropenia
ALL diagnosis
> 20 % blasts
ALL is what type of cell cancer
B cell mostly
ALL patients can have what gnetic
philidelphia chromosome
TKI added to chemo
ALL treatment layout
induction

ALL can hide where>?
brain and testes
give CNS prophylaxis
how can we do CNS prophylaxis for ALL
