🌱 來自: acute leukemia
diagnostic evaluation of acute leukemia
(Blood 2009;114:937)
Peripheral smear:
thrombocytopenia, blasts (seen in >95%; ⊕ Auer Rods in AML)
Bone marrow:
-
20% blasts
- mostly hypercellular
- test for cytogenetics and
- flow cytometry for immunophenotype (AML/ALL)
Cytogenetic anomalies:
AML
t(15;17), t(8;21), inv(16) or t(16;16), complex;
ALL
Ph-chromosome [t(9;22)], hyper or hypodiploid, complex
Molecular mutations
AML
- FLT3 (ITD and TKD),
- TP53,
- NPM1;
ALL
BCR-ABL1
Evaluate for complications
- TLS (↑ uric acid, ↑ LDH, ↑ K, ↑ PO4, ↓ Ca),
- DIC (PT, PTT, fibrinogen, D-dimer, haptoglobin, bilirubin),
- check for G6PD (prior to giving rasburicase)
LP
-
(w/ co-admin of intrathecal chemotherapy to avoid seeding CSF w/ circulating blasts)
-
all Pts w/ ALL
-
AML w/ CNS sx
-
CNS is sanctuary site
-
TTE before use of anthracyclines
HLA typing
- Pt,
- siblings >parents/children
- potential allogeneic HSCT candidates
