Leukemia Flashcards
Here is a handy image.
Maturation stages of blood cells.
What is Hematopoiesis?
The formation of blood cells
What is Leukemia?
Leukemia is the proliferation of malignanat WBC’s present in the circulation.
What does the suffix -blast, represent?
It represents immature forms of cells. Ex. Monoblasts are immature Monocytes, Erythroblasts are immature Erythrocytes
What does the suffix -cycts represent?
It represents a mature type of cell Ex. Monocytes, Neutrophils
In what demographic is Leukemia most prevelant?
Most common type of CA in children and young adults
Which two cell lineages is affected by Leukemia?
The Lymphoid and Myeloid lineages
How many different classifications of leukemia do we have?
4 Acute and Chronic Lymphocytic Leukemia Acute and Chronic Myelogenous Leukemia
Chronic is defined as:
Less aggressive It affects the more mature blood cells
Acute is defined as:
More aggressive It affects the immature cells, the blast cells
What is the cause of Leukemia?
Idiopathic - We do not know the cause, however, we do know that it is a mutation of gene’s.
What are some risk factors to developing Leukemia?
- genetic predispostion, and increased exposure to radiation (lower dose, frequent exposure like x-rays which target nucleus and genetic DNA) 2. immunodeficiency, t-cell leukemia virus (virus need host DNA to replicate, incorporating and altering host DNA) 3. non-malignant blood cell production also affected (restricted space in bone marrow, less room for production of normal cells, impaired immune response, and decreased oxygen supply)
Name the manifestations of Leukemia?
- anemia (decreased oxygen transport) 2. thrombocytopenia (decreased platelets) 3. leukopenia (decreased leukocytes) 4. bleeding gums, fever, generalized pain 5. fatigue, weakness, bruising 6. recurrent infections
What are the 3 treatment stages for Leukemia?
- induction 2. intensification 3. maintenance
How do you treat Leukemia?
Radiation, and Chemotherapy (Using the 3 treatment stages) Transfusions Antimicrobials Colony stimulating (CS) factors, also known as Blood Boosters
