AML Flashcards
Threshold concerning for leukostasis in AMl
50k
What is considered treatment related AML?
Exposure to prior chemo, radiation, or ***immunosuppressive drugs
Gene mutation associated with topoisomerase II inhibitors in AML
11q23 (II looks like an 11)
Timeframe for treatment related AmL from topoisomerase exposure
1-3 years post treatment
*No MDS phase
Drug classes associated with therapy related AML
- anthracyclines (topoisomerase II)
- alkylating agents (eg cytoxan)
Cytogenetic abnormalities associated with exposure to alkylating agents in AML
5 and 7 deletions (present 5 and 7 years after)
Timeframe for treatment related AML from alkylating agents
5-7 years
*preceeding MDS phase
Change in CEBPA classification for favorable risk category
- not biallelic. It’s now any bzip in frame mutated CEBPA
Risk stratification of FLT3 in AML
All intermediate now regardless of NPM1 (improved outcomes from FLT3 targeted therapy)
Indications for LP for de novo AML
1) WBC>30K
2) monocytic or myelomonocytic
3) FLT3 mutant
AND symptomatic
Initial management of leukostasis
- hydrea
- Given myeloid lineage on flow, 1-2 g cytarabine (can also be used) vs. cytoxan
Allopurinol mechanism of action
inhibits xanthine oxidase
Rasburicase mechanism of action
catalyzes enzymatic oxidation of poorly soluble uric acid into an inactive and more soluble metabolite allantoin
What is core binding factor AML?
AML with inv(16) or t(8;21)
Standard of care for CBF AML
7+3 + gemtuzumab ozogamicin (dramatic improvement in outcomes)
1) gemtuzumab mechanism 2) SE’s to know with gemtuzumab
- increased risk of VOD (sinusoidal obstruction syndrome)
- myelosuppression
- increased liver toxicity
generic name of vyxeos
liposomal-daunorubicin/cytarabine
Treatment options for frail patient that is IDH1 mutant
1) HMA + venetoclax
2) HMA + ivosidenib 500 mg daily for at least 2 years + HMA q28 days (Preferred -AGILE - OS 24 vs. 8 months)
High dose cytarabine (HiDAC) SE to know + management
- cerebellar toxicity
- permanent discontinuation
Prophylaxis required when giving HiDAC
Steroid eye drops
Blast cutoff for AML diagnosis
Greater than 20%
What is 7 + 3
7 days cytarabine
3 days anthracycline
IDH1 targeted drug
Ivosidenib
IDH2 targeted drug
Enasidenib
