Q

How do you manage differentiation syndrome?

A

Steroids (Dex 10 mg BID)
Hold ATRA if renal/pulmonary failure

-For high risk APL, can consider prophylactic dexamethasone but that’s controversial

Q

Induction chemotherapy for AML with FLT3-ITD mutation?

A

7+3+Midostaurin
Only if patient is under 60

22
Q

What is the mechanism of Quizartinib?

A

FLT-3 ITD mutation inhibitor.
**Will not work for FLT3-TKD

23
Q

What is the indication for Gilteritinib?

A

Relapsed/refractory AML FLT3-mutated AML

24
Q

Standard induction chemotherapy for fit patients with sAML or tAML?

25
What are four clinical criteria to deem a patient elderly/not-fit for intensive induction chemotherapy?
Age >75 CHF requiring treatment or EF <50% DLCO <65% or FEV1 <65% ECOG 2-3
26
Standard induction chemotherapy for unfit patients with AML
Azacitidine + Venetoclax
27
Mechanism of action of Venetoclax
BCL-2 inhibitor. BCL-2 stabilizes mitochondria and prevents activation of proapoptotic proteins. So, inhibiting BCL-2 enables apoptosis
28
Mechanism of action of Ivosidenib
Inhibits IDH1
29
3 Indications of Ivosidenib
R/R AML with IDH1 mutation 1st line monotherapy for IDH1 mutated AML for frail individuals 1st line in combination with azacitidine
30
What is the standard post-remission consolidation treatment for favorable risk AML?
HiDAC If CD33+, can get gemtuzumab
31
You have a patient with AML in CR2, what is the best next step?
AlloHCT.
32
When would you consider an alloHCT for a patient with favorable risk AML?
when they cannot tolerate/complete consolidation chemotherapy, or are MRD+
33
How do you manage cerebellar toxicity due to cytarabine?
Stop cytarabine and don't rechallenge
34
A patient goes through induction chemotherapy with 7+3 + Gemtuzumab. They can't tolerate HiDAC consolidation and so are going through transplant. What AE are they at higher risk for?
SOS/VOD
