Primary Myelofibrosis (PMF)
Clinical signs
  • proliferation, especially of the magakaryocytic and granulocytic lineages, associated with fibrosis
  • 2 stages:
    • pre-fibrotic/cellular
    • fibrotic
  • early symptoms are non-secific, in later stages symptoms include anemia, organomegaly, subfebrile temperatures, fatigue, weight loss
  • prognosis: median survival time is approx. 3 – 7 years for patients diagnosed in the fibrotic stage and approx. 10 – 15 years for patients diagnosed during the early pre-fibrotic stage, 5 – 30% of patients develop AML
Histology
  • pre-fibrotic stage: hypercellular bone marrow, clusters of increased numbers of large megakaryocytes with hyperlobated nuclei, dysplastic megakaryocytes, a relative increase in granulopoiesis (M : E ratio is approx. 5 : 1), none or only slight fibrosis (MF-0 or MF-1)
  • fibrotic stage: extensive fibrosis of the bone marrow (MF-2 nebo MF-3) with residual hematopoiesis, clusters of dysplastic megakaryocytes, dilatated sinuses with hematopoietic cells, osteosclerosis, extramedullar hematopoiesis
