25
IF you see tons and tons of auer rods what should you be thinking of?
promyelocytic leukemia
26
What is the pathogenesis behind the APL translocation?
balanced translocation b/w RARA and PML that results in a fusion product that arrests the cell at the maturational stage so it cant progress from promyelocyte to myelocyte.
27
What is RARA and what does this mean for APL?
it is a retinoid acid receptor alpha (receptor for vit A) so this means if you get APL you can cure it by taking vit A and an alkylating agent
28
APL has a translocation between chromosome (blank) and (Blank)
15 and 17
29
How do you treat acute promyelocytic leukemia?
ATRA and alkylating agent | 80-90% remission
30
What is this: auer rods are rare gum infiltration is frequently the presenting sign
Acute monocytic leukemia
31
What is this: 15% of adult leukemias may be related to radiation or benzene pluripotent t (9,22) BCR-ABL fusion gene AKA philadelphia chromosome Protracted chronic phsae, sometimes many years, followed by blast crisis
Chronic myelogenous leukemia
32
What are the chromosomes involved in chronic myelogenous leukemia?
9 and 22
33
What is the are the fusion genes associated with CML?
BCR-ABL fusion gene AKA phildelphia chromosome
34
Chronic myelogenous leukemia has a (blank) chronic phase, sometimes many years, followed by blast crisis
protracted
35
Philadelphia chromosome is caused by a (blank) mutation
de novo
36
Is the philadelphia chromosome specific for CML?
no
37
(blank) fusion gene produces a constitutively active tyrosine kinase, leading to dysregulation of proliferation and normal apoptosis.
BCR-ABL1
38
The BCR-ABL1 fusion product primarily deals with the (blank) pathway
STAT5 pathway
39
In chronic myelogenous leukemia, the WBC count is greater than (blank)
5X10^9
40
``` What is this: splenomegaly bleeding/ecchymoses fever, night sweats, weight loss less than 10% blasts Characteristic diffusion, with full spectrum of granulocytes represented ```
Chronic Myelogenous Leukemia
41
Why do you get splenomegaly in CML?
deposition of messed up neutrophils
42
(blank) is the terminal stage of chronic myelogenous leukemia that is characterized by a marked increase in the proportion of blast cells, by fever and pain in the bones, and by increased severity of anemia, thrombocytopenia, and splenomegaly—called also blastic crisis
Blast phase (crisis)
43
``` What is this: progression to acute leukemia greater than 20% blasts large aggregates in BM and extramedullary tissue Usually fatal ```
Blast phase (crisis)
44
CML-> deposition of malignant cells in his tissues. (blank) is when CML has reached blast breaking point and then wil go into acute ML. Rapidly fatal. (blast count above 20% makes chronic turn to acute)
Blast crisis
45
How do you treat CML?
with tyrosine kinase inhibitors (imatinib, gleevec) | and allogenic stem cell transplant
46
In CML, allogenic stem cell transplants, give you a 5 year progression free survival in (blank) percent of patients
80-95%
47
What is the most common leukemia in children?
B cell acute lymphoblastic leukemia
48
Which is more prevalent B cell acute lymphoblastic leukemia or T cell acute lymphoblastic leukemia?
