signaling pathway involved
tyrosine kinase
chronic pahse
acute blast phase
> 20% blasts
marrow failure
acute blast phase
> 20% blasts
marrow failure
polycythemia vera
increased proliferation of erythroid precursors JAK2 mutation male issues due to high viscosity blood poikilocytosis treatment- phelobotmy decreased EPO increased RBC mass in proliferative phase only spent phase- normal/decreased RBC mass

marrow failure
chronic myelogenous leukemia
increased proliferation of granulocytes, specifically basophils
9,22 translocation- BCR/ABL fusion protein (philadelphia chromosome)
splenomegaly
treatment- imatinab
LAP negative
polycythemia vera
increased proliferation of erythroid precursors JAK2 mutation male issues due to high viscosity blood treatment- phelobotmy decreased EPO increased RBC mass in proliferative phase only spent phase- normal/decreased RBC mass
essential thrombocytopenia
increased platelets JAK2 mutation 30y female avoid splenectomy doesn't progress to marrow fibrosis or acute leukemia
primary myelofibrosis
increased megakaryocytic JAK2 mutation splenomegaly- extra medullary hematopoiesis poikilocytosis marrow fibrosis leukoerythroblastic smear
