What cytogenetic abnormalities qualify as AML regardless of the blast count?
t(8;21), inv (16), t(9;11), t(6;9), inv3, mutated NPM1, in frame bZIP mutated CEBPA, t(9;22), and t(15;17)
What are some favorable risk cytogenetics for AML?
Biallelic mutated CEBPA (bZIP in frame mutated CEBPA), mutated NPM1 w/o FLT3 ITD or with FLT3 ITD low, inv 16, t(16;16), t (8;21)-RUNX1/RUNX1T1
Wild type NPM1 and FLT-3 ITD high confer what kind of risk in AML?
Intermediate risk disease. (take note the previous answer I had here was high risk, but looking at resources it is intermediate risk)
Mutated RUNX1, ASXL1, and TP53 mutation carry what kind of risk in AML?
High risk disease
In regards to NPM1 mutations what are the combinations that give you intermediate risk disease? What other cytogenetic translocation qualifies as intermediate risk disease?
Mutated NPM1 and FLT3 ITD high, wild type NPM w/ FLT-3 ITD or without FLT-3 ITD or FLT3 ITD low
t(9;11)
What is the typical translocation found in APL?
t(15;17) PML;RARA
What is a atypical chromosome translocation that can be seen in APL? What is the clinical significance?
t(11;17) This translocation is not responsive to ATRA, you will need to use AML directed chemo
What is defined as high risk APL and what is the tx?
Greater than 10 K WBC, you start dexamethasone.
What are the flow results for APL?
HLA-DR-, CD33, CD13+, CD34-
What are the tx options for high risk APL?
ATRA/ATO plus Gemtuzumab Ozogamicin (preferred)
ATRA/ATO plus Idarubicin (preferred)
You can use ATRA with Daunorubicin and Cytarabine if ATO for some reason is contraindicated or ATRA with Idarubicin as well
What is the induction regimen used for FLT3 ITD or TKD?
What induction regimens do you use for low risk core binding AML? t(8;21), inv 16, t(16;16)
What is tx for favorable risk by molecular mutation (mutated NPM1 w/o FLT3 mutation, bZIP in frame mutation of CEBPA) and intermediate risk AML?
7+3 (dauno or Ida) (Cat 1)
7+3 (mitoxantrone) for 60 and older
What is the induction regimen preferred for TP53 and/or del17p?
New updated recommendation per NCCN: Clinical Trial. Below are the older recommendations:
1. 7+3 (cat 1 rec)
2. 7+3 (mitoxantrone) for 60 and older
3. HiDAC+ dauno or Ida+ Etoposide (cat 1 rec)
What is the induction therapy for therapy induced AML or antecedent MDS/CMML/ MDS related cytogenetic changes (meaning they had MDS transform to AML)?
What is the mechanism of action of Gemtuzumab?
It is a antibody drug conjugate against CD33, callcheamicin is released causing double stranded DNA breakage
When using Gemtuzumab the benefit was only shown in what group of AML patients?
There is only a OS benefit with good risk disease.
What is the induction regimen of choice in elderly patients or those less fit with multiple comorbidities w/a IDH1? What if they don’t have a IDH1 mutation?
IDH1: Ven with Aza (Cat 1) or Decitabine. Azacitidine with Ivosedenib (Cat 1). Ivosedenib alone is an option, just not preferred.
No IDH1: Azacitidine w/Venetoclax (Cat 1) or Decitabine w/Venetoclax
Gilteritinib is approved for what?
Adults with relapsed/refractory FLT3 mutated AML, both ITD and TKD.
What treatment do you give for IDH2 mutation and what is the indication?
Updated guidelines: Enasidenib for relapsed/refractory disease with a IDH2 mutation.
What are the side effects seen with Ivosidenib and Enasidenib?
Ivosidenib-diarrhea, pyrexia, fatigue
Enasidenib-nausea, fatigue, increased bilirbuin, diarrhea.
Differentiation syndrome for both!
What are the tx options for relapsed disease if you have a FLT3 ITD mutation?
Gilternitib or Azacitidine/Decitabine plus Sorafenib
Quizartinib-Cat 2B
What are the tx options for relapsed disease with FLT3-TKD? IDH 1 and 2?
Gilternitib alone-TKD
IDH1-Ivosidenib and Olutasenidib
IDH2-Enasidenib
What is the treatment for relapsed CD33 AML?
Gemtuzumab
