16
Q

True or False: A common feature among AML and ALL is the failure to maintain balance of proliferation, differentiation, and apoptosis.

A

True

17
Q

True or False: AML and ALL each arise from a single leukemic cell, usually a blast.

A

True

18
Q

This is a phenomenon in leukemia called ________, in which there is rapid cellular growth of leukemic cells in the bone marrow that crowds the bone marrow and causes decreased production of other blood cell counts. These blasts eventually become too packed in the bone marrow and split out into circulation.

A

“Crowding Out”

19
Q

Which of the following is a rare symptom in the presentation of leukemia?
A. Thrombocytopenia resulting in bruising, petechiae, and bleeding
B. Splenohepatomegaly from accumulation of blast cells there
C. Anemia resulting in fatigue and loss in energy
D. Chloromas resulting in bluish spots under the skin which are leukemic cells.
E. Leukopenia resulting in fever, chills, and rigor

A

D. Chloromas resulting in bluish spots under the skin which are leukemic cells.

20
Q 
The most important test for diagnosis of leukemia is:
A. CBC with differential
B. Peripheral blood smear
C. Bone marrow biopsy and aspirate
D. Lumbar puncture
E. Chest radiograph
A

C. Bone marrow biopsy and aspirate

21
Q 
Which of the following types of leukemia can be characterized by Auer rods on peripheral blood smear?
A. ALL
B. AML
C. CLL
D. CML
A

B. AML

22
Q

True or False: Problems with coagulation are frequently seen in ALL, and are not seen often in AML.

A

False! They are seen AML, not in ALL.

23
Q

Regardless of how many blasts are in the peripheral blood, a blast percentage of greater than ___% in the bone marrow, which is checked through bone marrow aspirate, is indicative of AML.

A

20%

24
Q

True or False: An AML patient can present with leukopenia OR leukocytosis.

A

True (leukocytosis due to blasts in periphery)

25
Q

______ is an enzyme on the myeloid precursor that is specific for AML. A dye is used to look for this enzyme, and if it is positive, it almost always means AML.

A

Myeloperoxidase (MPO)

26
Q 
Of the following possible mutations that can occur in AML, which are correlated with a good prognosis?
A. NPM1
B. t(9;22)
C. c-KIT
D. CEBPA
E. FLT3-ITD
A

A. NPM1

D. CEBPA

27
Q

Describe the 7+3 induction regimen that is used in AML patients.

A

Give cytarabine 100-200 mg/m2 continuous infusion on days 1-7 and you give an anthracycline like daunorubicin or idarubicin IVP on days 1-3.
