AML Flashcards
Median age AML
65 yo (rare in general, mostly elderly)
Risk factors AML
benzene, XRT, Downs, prior chemo (sp etoposide and alkylating agents), Faconi, Diamond Blackfan
What is Sweet syndrome
Inflammatory rxn with fever and painful violaceous scutaneous lesions
How can a pt be diagnosed
- Genetics
or
2a. 20%+ blasts in marrow or peripheral blood AND
2b. Myeloid origin proven by Auer rods or flow cyometry
Defining genetic mutations for AML
t(8,21)
inv(16)
t (16,16)
t(15,17)
What’s the general name of test for molecular markers?
Rapid heme panel testing
Poor prognostic markers
Mutations:
FLT3-ITD
RUNX1/ASXL1/TP53
Induction Tx: <60 yo
Induction with goal of CR
“7+3”: cytarabine cont infusion x 7d; daunorubicin bolus on d1-3
Check BMBx @ d14 w/ goal of <5% blasts, if not, re-induce with 5+2
2nd line tx: <60
HiDAC
1st line consolidation tx <60 yo
Goal: Eliminate undetectable residual dz.
3-4 cycles HiDAC.
Adverse risk consolidation tx
allo HCT
What tx would you add to induction if FLT3 positive
midostaurin
1st line consolidation tx >60 yo
“5+2” cytarabine + daunorubicin or IDAC
Onc emergency that occurs early in consolidation tx when pt has high WBC
TLS
Older pt not eligible for chemo tx
Venetoclax + hypomethylating agent
Hypomethylating agents include
decitabine (dacogen), azactitdine (vidaza)
HiDAC main AEs to monitor for
cerebellar toxicity (daily neuro checks), conjunctivitis (dex drops)
What is the use for hydrea (hydroxyurea)
off-label, cytoreduction of WBC
Dose of cytarabine for 7+3 induction
100-200 mg/m2 IVCI
Dose of daunorubicin for 7+3
90 mg/m2 IVP
Be mindful of this toxicity with daunorubicin
cardiotoxicity; ensure EF >45% at start
What anti-emetic to rx with 7+3
Zofran 16 mg qd
Ppx for TLS includes…
allopurinol 300 mg qd
sufficient IVF for UOP >100cc/h
How many patients need the 5+2 induction phase
1/4 - 1/3
Length of stay in hospital for treatment
4-6 weeks
SE of typical tx:
myelosuppression, aloppecia, rash, mucosititis, n/v/d
When ok to d/c
ANC >500
d/c instructions
- Need for antiemetics?
- f/u onc 5-7d
How many cycles does someone typically get of HiDAC for consolidation
3-4
For how long does one use the dex eye drops for HiDAC
prior to chemo until 72 hours post final dose
Length of stay for consolidation
5-6 days
Ppx hand-foot syndrome with consolidation
Nicotine patch + oral steroids
Dispo following HiDAC consolidation
- dex eye drops
- anti-nausea meds
- mouth care
- ppx abx (cipro/levo - up to onc)
- 2x weekly labs
When do counts recover following d/c for HIDAC
~28d
Whats the tx for relapse/refractotry AML
ME/MEC/HAM
Goal of ME/MEC/HAM
Induce remission prior to allo SCT
What to check before starting ME/MEC/HAM (specific to mitoxantrone)
TTE, ensure EF > 45%
