WBC Disorders Flashcards
Lymphoma vs Leukemia?
Lymphoma - malignant proliferations of lymph tissue that produce tumor
Leukemia - Malignant cells of bone marrow that spill into the peripheral blood
What is Hodgkin Lymphoma?
A lymphoma of a distinctive cell type (Reed-Sternberg cell) that arises in a single lymph node
Highly curable
What ages are most likely to get Hodgkin Lymphoma?
20-30 yrs old or over 50
T/F: Hodgkin Lymphoma presents with a painful lymphadenopathy.
FALSE
Tumor is painless
What is present in 70% of Reed-Sternberg cells?
Epstein-Barr virus
What is needed for diagnosis of Hodgkin Lymphoma?
Biopsy of lymph node and identification of RS cell in appropriate background
What is the origin of a RS cell?
Germinal center B lymphocyte
What is the stage of a Hodgkin lymphoma that is on both sides of the diaphragm?
Stage III
What is needed to be a stage IV Hodgkin lymphoma?
Tumor in organs other than lymph nodes, spleen, or Waldeyer’s ring
Describe a tumor that is Stage II B?
Tumor is in more than two anatomic regions but on the same side of the diaphragm.
B = clinical symptoms are seen (fever, night sweats, weight loss)
T/F: Most non-hodgkin lymphomas are of B cell origin.
True
What age group is most likely to get NHL?
Over 40
T/F: Hodgkin lymphoma is more common than NHL?
FALSE
T/F: Nodular NHL disease has better prognosis than diffuse NHL disease.
True
T/F: Small cell NHL is better than large cell NHL.
True
What constitutes for high stage NHL?
Numerous sites of involvement or bone marrow involvement
What makes prognosis of NHL different than other cancers?
Grading or sub-typing is more important than staging
What are the characteristics of acute leukemia?
- Rapid onset with blasts in blood
2. Myeloid and lymphoid cells affected
What are the characteristics of chronic leukemia?
