Leukemia/Lymphoma Flashcards
With an Acute Leukemia, what cells predominate in the blood/BM?
> 20% BLASTS
With a Chronic Leukemia, what cells predominate in the blood/BM?
Mature cells – NOT blasts
What specific finding in the cells will be seen with Acute Myeloid Leukemia?
Auer rods
How do you treat AML with Auer rods?
ATRA – All trans retinoic acid
What marker will be positive with Acute Myeloid Leukemia?
MPO (+)
What markers (2) will be positive with Acute Lymphocytic Leukemia?
Tdt
CaLLa
Acute Lymphocytic Leukemia has a predilection for the CNS. What should be given in addition to chemo/radiation?
ARA-c for CNS disease
What translocation is present with Chronic Myeloid Leukemia?
9;22 = BCR-ABL fusion
What translocation is present with Chronic Myeloid Leukemia?
9;22 = BCR-ABL fusion
The BCR-ABL fusion creates a tyrosine kinase protein for CML. What is the specific treatment?
Imatinib (TK inhibitor)
If a patient has NONtender LAD, what is the best next step?
Excisional biopsy
Following an Excisional biopsy for NONtender LAD, what 3 things need to be done to stage?
CXR
CT abdomen/pelvis/chest
BM biopsy
What cells are seen with Hodgkin’s Lymphoma?
Reed Sternberg cells
= Bi-lobed Nuclei
Lymphomas often present with what?
NONtender LAD
What are the B symptoms?
Fever
Night sweats
Weight loss
Pruritus
What is unique about the LAD with Hodgkins’s Lymphoma?
May become painful after alcohol consumption
What are Plasma Cell Dyscrasias?
Monoclonal expansion of plasma cells in the BM
List 3 Plasma Cell Dyscrasias
- Multiple Myeloma
- MGUS
- Waldenstrom’s
What occurs with Multiple Myeloma?
Monoclonal plasma cells secrete IgG, Bence Jones Proteins and (+) Osteoclasts
Pneumonic to remember Multiple Myeloma symptoms?
CRAB
Signs of Multiple Myeloma?
CRAB
- Hypercalcemia
- Renal disease
- Anemia
- Bone pain with lytic lesions
First test to obtain if concerned about a Plasma Cell Dyscrasia?
SPEP (serum electrophoresis)
With Multiple Myeloma, what will the Spep, Upep and skeletal survey be?
(+)!!
Spep = M spike
Upep = M spike
What will be seen on BM biopsy that defines Multiple Myeloma?
> 10% plasma cells
What will be seen on BM biopsy that defines Multiple Myeloma?
> 10% plasma cells
With MGUS, what will be the result of the Spep, Upep and skeletal survey?
ONLY the Spep is (+)!!
= M spike
With MGUS, the patient will likely be asymptomatic with what?
Elevated protein gap > 4
Treatment for MGUS?
Observe to see if it transitions into Multiple Myeloma
What do the plasma cells secrete with Waldenstrom’s?
IgM
How will Waldenstrom’s present?
Hyperviscosity syndrome
– tortuous retinal veins!
What will a BM biopsy show with Waldenstrom’s?
> 10% LYMPHOMA
What will a BM biopsy show with Waldenstrom’s?
> 10% LYMPHOMA
What is the treatment for Waldenstrom’s?
Rituximab
First test to get that is likely positive with all etiologies of Plasma Cell Dyscrasias?
Spep!
Signs of Multiple Myeloma?
CRAB
- Hypercalcemia
- Renal disease
- Anemia
- Bone pain with lytic lesions
What is a possible complication of AML?
Life-threatening hemorrhage
