    Abstract:
    A series of 24 consecutive patients affected by myelofibrosis with myeloid metaplasia was reviewed. The clinical-pathological features at onset were similar to those reported in literature; in particular in all the patients we observed splenomegaly and the typical leuko-erythroblastic picture in peripheral blood. The median survival of our series was of 57 months; the deaths were caused by severe anaemia and/or infection and/or haemorrhage; the blastic terminal transformations were rare. According to other authors, unfavourable prognostic factors in our patients were: male sex, advanced age, hepatomegaly, the presence of systemic signs, anaemia, leukocytosis, leukopenia, high number of circulating erythroblasts, thrombocytopenia, osteomyelosclerosis. We have confirmed the clinical value of three staging prognostic systems: the system proposed by Njoku based on haemoglobin level and reticulocytes number, the system proposed by Visani based on haemoglobin and circulating myeloid precursors number, the system proposed by Dupriez based on haemoglobin and white blood cells number.
