AML immunophenotype
CD13+, CD33+, MPO+, CD34+
26
Morphologic CR in AML
<5% blasts
27
Consolidation for patient requiring 2 inductions in AML in CR2
Allo-HSCT
28
Options for relapsed/refractory AML - "remission reinduction"
1) salvage combination chemotherapy followed by allo-HSCT (Phase 2 -- impressive response rates but very toxic) 2) HMA + venetoclax if not received upfront, then allo-HSCT 3) Clinical trial followed by allo-HSCT 4) Add targeted therapy if available: Given IDH mutation, add IDH inhibitor to regimen, e.g. HMA/venetoclax Given FLT3 ITD or TKD mutant (prior FLT3 doesn’t exclude), gilteritinib followed by allo-HSCT (OS benefit) Given CD33 and not used previously, gemtuzumab followed by allo-HSCT
29
Most commonly used systemic therapy regimens for re-induction
(FLAG-IDA + venetoclax) MEC
30
What is FLAG-IDA?
Fludarabine, cytarabine, plus G-CSF , idarubicin
31
What is MEC?
M - mitoxantrone E - etoposide C - cytarabine
32
Favorable risk AML mutations
1) t(8;21)(q22;q22.1)/RUNX1::RUNX1T1 2) inv(16)(p13.1q22) or t(16;16)(p13.1;q22)/CBFB::MYH11 3) Mutated NPM1 without FLT3-ITD 4) bZIP in-frame mutated CEBPA
33
Other AML RF's
Benzene
34
Germline mutations associated with increased risk of AML
CEBPA DDX41
35
AML defining genetic abnormalities
*NPM1 + RUNX1:RUNX1 + CBFB:MYH11 + DEK::NUP214 + RBM15::MRTFA fusion + KMT2A + MECOM + NUP98 + CEBPA
36
What is the answer in terms of genetic abnormality with question showing peripheral smear full of eosinophils?
AML with inversion 16
37
Management of AML with inversion 16
gemtuzumab
38
What is AML-MRC?
AML with myelodysplasia related changes?
39
Board answer to management of Down syndrome patient with MPN + mutation
- observation (erythromegakaryocytic MPN, it spontaneously resolves over the first few months of life) - GATA1
40
Genetic abnormality for patient presenting with basophilia
t(6;9)
41
Genetic abnormality associated with AML presenting with thrombocytosis
inv(3) or T(3;3)
42
What does quizartinib target
FLT3-ITD *not TKD
43
Giltertinib approval
Relapsed/refractory, not induction
44
Common mutation in therapy related AML
TP53 (30-40%)
45
Management of p53 mutant AML
clinical trial (we have no good standard therapies)
46
Standard for defining who is ineligible for induction chemotherapy in AML
- Age >75 - CHF requiring treatment or EF <50% - DLCO <65% or FEV1 <65% - ECOG 2-3, can be disease dependent
47
Board answer for elderly patient unfit for induction chemo
HMA + venetoclax
48
Venetoclax dosing w/ HMA + venetoclax
- continuous is board answer - small but compelling abstract for 14 days so a lot of centers are using 14 day dosing
49
New IDH inhibitor recently approved
olutasidenib (only approved in relapsed/refractory setting)
50
Preferred conditioning and clinical benefit for patients MRD+ prior to transplant
- myeloablative conditioning (OS benefit vs. RIC w/ genomic evidence of disease prior to transplant)

Age as a RF for AML
Age over 65 is an independent predictor of poor prognosis
