Working classification of chronic myeloproliferative disorders based on histological, haematological, and clinical findings.

Bone marrow biopsies of 850 patients with chronic myeloproliferative disorders were taken at initial diagnosis; and 169 sequential biopsies over periods of one to 188 months. Three micron sections of all biopsies were evaluated semiquantitatively with reference to the proliferating cell lines, anomalies of megakaryocytes, and fibrosis or osteosclerosis. Correlations between initial histological...

Chronic myeloproliferative disorders: prognostic importance of new working classification.

Variants of chronic myeloproliferative disorders (CMPD) were compared according to their clinical features and classified by bone marrow biopsy appearances. Subsequently, this classification was further evaluated using survival data and histological variables from iliac crest biopsy specimens of an additional 1391 patients, making a total of 2241 patients available for analysis of outcome. The ...

Chronic Myeloproliferative Disorders

JAK2, an acquired mutation of JAK2, is present in a majority of patients with polycythemia vera and to a lesser extent among patients with the other myeloproliferative disorders. We analyzed the effect of JAK2 on the expression of polycythemia rubra vera 1(PRV-1), using an in vitro model. Compared to wild-type JAK2, the presence of JAK2 increased both PRV-1 protein and mRNA levels in murine mye...

Chronic myeloproliferative disorders.

The Philadelphia chromosome-negative chronic myeloproliferative disorders (CMPD), polycythemia vera (PV), essential thrombocythemia (ET) and chronic idiopathic myelofibrosis (IMF), have overlapping clinical features but exhibit different natural histories and different therapeutic requirements. Phenotypic mimicry amongst these disorders and between them and nonclonal hematopoietic disorders, la...

Histological and molecular classification of chronic myeloproliferative disorders in the age of JAK2: persistence of old questions despite new answers.

The discovery of the Janus kinase 2 gain-of-function V617F mutation (JAK2(V617F)) provided a major breakthrough in the understanding of Philadelphia chromosome-negative chronic myeloproliferative disorders (Ph(-) CMPD). Among haematologic neoplasm the mutation appears to be almost specific for Ph(-) CMPD but the different entities comprising polycythaemia vera (PV), essential thrombocythaemia a...
