MDS/AML/ALL Flashcards
Based on Revised -IPSS Very good karyotype Good karyotype Poor karyotype Very poor karyotype
Very good = -Y, def(11q)
Good = normal, del(5q), del(12p), del(20q), or double abnorm including del(5q)
Poor = -7, inv(3)/t(3q), double abnorm including -7/del(7q)
Very poor = complex karyotype (3 or more abnormalities)
Lenalidomide in MDS
Indicated for low/interm-1 risk MDS with symptomatic or transfusion dependent anemia + del(5q) as sole cytogenetic abnormality
10mg lenalidomide daily
ESAs in MDS
When EPO < 500
When Epo <100 and less than 2 transfusions per month – chance of responding to ESAs is 75%
CMML
Overlap between MDS and MPN MDS features (dysplasia, anemia, thrombocytopenia) and MPN features (leukocyosis, monocytosis, splenomegaly)
Characterized by absolute monocytosis 1000 or greater, persistent for > 3 months with no other etiology
CCUS
ICUS
CHIP
CCUS: clonal cytopenias of undetermined significance
- unilineage or multilineage cytopenias and clonal hematopoeisis
ICUS: idiopathic cytopenias of undetermined significance
- unilineage or multilineage cytopenias and NO clonal hematopoeisis
CHIP: clonal hematopoesis of undetermined potential
- excludes clinically significant cytopenia but WITH evidence of clonal hematopoeisis
When to use luspatarcept?
Luspatarcept – Approved for treatment of anemia failing ESA and requiring 2 or more RBC units over 8 weeks (2 months) in adult patients with very low- to intermediate-risk MDS with ring sideroblasts or with MDS/MPN with ring sideroblasts and thrombocytosis. MOA = recombinant fusion protein that binds transforming growth factor-beta ligands to reduce SMAD2 and SMAD3 signaling.
Treatment of PV
Age <60 and no hx of thrombosis = aspirin + phlebotomy
If Age >60 Hx of thrombosis Acquired VWD Symptoms --> add HU
Use Rux instead of HU if inadequate response to HU
Treatment of EV
Age <60 and no other risk factors = aspirin
If Age >60 Hx of thrombosis Acquired VWD Symptoms --> add HU
APL high risk classification and treatment
WBC > 10
Give ATRA AND 7+3 (arsenic not needed)
Chemotherapy agents causing AML/MDS - Time frame?
Topoisomerase inhibitors (including anthracyclines) - 1-2 yrs
Alkylating agents - longer, often with preceding MDS first
Poor risk genetics for AML
t(6;9) inv3 t(9;22); BCR-ABL1 FLT3 positive ASXL1 RUNX1 TP53 MLL (11q23) Complex or monosomal karyotype
Good risk genetics for AML
t(15;17); PML-RARA t(8;21) Inv(16) t(16;6) Biallelic mutated CEBPA* FLT3 negative NPM1 mutation With FLT3 negative/low IDH2
Poor risk genetic factors for ALL
Philadelphia chromosome t(9;22) Ph-Like t(4;11) (KMT2A) Complex cytogenetics Hypoploidy
CMV status ideal for transplant
CMV status is WORSE if recipient CMV+ and donor CMV- because then recipient could reactivate (as they have ab)
Treatment for relapses B-ALL
These are for B (not T ALL)
Blinatumomab = Bi-specific T-cell Engager (BiTE), targets CD3/CD19
1st or 2nd remission with minimal residual disease
Inotuzumab = CD22+ antibody drug conjugate; carries chemotoxin calicheamicin
Clofarabine - Pts 1-21 with 2 or more prior therapies
CAR-T for young adults - Pts < 26 with refractory disease or 2 or more relapses
