down syndrome
What is the common finding for hemoglobin, platelet, and neutrophil and leukocyte count for acute leukemia?
anemia, neutropenia, thrombocytopenia, and leukocytosis
acute myeloid leukemia arrests cells in what stage?
myeloblast
ALL arrest cells in what stage?
lymphoblast pre-b and pre-t cells
B-Cell/T-cell ALL has a worse prognosis?
T-cell
what is common with T-cell ALL
mediastinal mass that is termed t cell lymphoblastic lymphoma
AML can arise from
other disease like myeloproliferative or de novo mutation
three factors for bad prognosis for AML
- increased age
- having previous disease or treatment
- deletion of 5 and 7 chromosome

what is characteristic of CML blood smear?
increased basophils
heterogenous
Increased myeloid to erythroid ratio
what happens if CML is not treated?
it can form acute leukemia
Rai classification for leukemia?
