Hema Flashcards
A rapidly progressive neoplasm derived from hematopoietic precursors, or myeloid stem cells that differentiates to monocytes, granulocytes, erythrocytes, and platelets.
Most common type of acute leukemia in adult.
Acute Myeloid Leukemia
H
H
Uncontrolled proliferation of immatuere cells (lymphoblasts) derived from the lymphoid system.
Most common childhood leukemia
Overall cure rate is more favourable in children than in adults.
Acute Lymphoblastic Leukemia
H
H
Characterized by the presend of Philadelphia chromosome (Ph1) translocated to chromosome 9; forms bcr-abl gene producing tyrokinase protein.
Arises from the mutation in the myeloid stem cell. Normal myeloid cells is produced but pathologic increse in the production of blast cells.
3 clinical phases: chronic 10%, accelerated 15%, blast crisis >20%
Chronic Myeloid Leukemia
H
H
H
H
Excessive accumulation of mature leukemia cells in the bone marrow and circulation.
Common malignancy in older adults.
Chronic Lymphocytic Leukemia
The cancer cells are called Reed-Sternberg cells, an abnormal type of B lymphocytes.
Originates from lymphocytes in the lymphatic system.
