Hematology Week 2: Neoplastic Hematology Flashcards
Heme Neoplasms polyclonal vs clonal
heme neoplasms are clonal - all derived from the same transformed cell
heme neoplasms cell stage
- immature heme neoplasm
- mature heme neoplasm
how do heme neoplasms look?
main categories of heme neoplasms
Leukemia definition
A heme neoplasm with mainly WBC proliferation that predominantly involves the blood and the bone marrow
Normally these cells travel to bone marrow to blood to the lymph node, however, heme neoplasms can also move but where most of the cells are found is what they are called
Lymphoma Definition
Heme Neoplasm of lymphoid cells that predominantly involves the lymph node and tissue
Normally these cells travel to bone marrow to blood to the lymph node, however, heme neoplasms can also move but where most of the cells are found is what they are called

Question 1
Acute vs Chronic Leukemia
Acute Leukemias maturity and cell type
Immature cells (blasts) predominate
Acute Leukemias immaturity is caused by?
Maturation failure, acquired genetic alterations that inhibit their maturation
Acute Leukemias Threat and treatment
- Aggressive
- require potent curative intent therapy including HSCT
Chronic Leukemias maturity
Mature cells predominate
Chronic Leukemias Maturation
- Maturation is intact
- although they are neoplastic the clonal cells can still differentiate
- Acquired genetic alterations but maturation ability is intact
Chronic Leukemias Threat and Treatment
- More indolent
- therapy is not usually curative in intent
