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

چکیده
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 findings, clinical, haematological, and survival data were analysed statistically. The predominant cell lines distinguished the classical entities of polycythaemia vera, primary thrombocythaemia, and chronic myeloid leukaemia and correlated with their different prognoses, while megakaryocytes characterised subgroups that were prone to fibrotic or blastic transformation. Based on the initial histological, clinical, and haematological data analysed a working classification of chronic myeloproliferative disorders was proposed that permits recognition of both typical and atypical cases of chronic myeloproliferative disorders.

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 ...
متن کاملDiagnosis of Allergic Fungal Rhinosinusitis
Background: Allergic fungal sinusitis is a non-invasive disease, and accounts for approximately 6-8% of all chronic sinusitis requiring surgical intervention. As the treatment and prognosis of these disorders vary significantly, it is extremely important to recognize allergic fugal sinusitis and differentiate it from chronic sinusitis of bacterial and fungal origin. This prospective study evalu...

متن کاملCerebral venous thrombosis as presenting sign of myeloproliferative disorders.
Two patients with cerebral venous thrombosis are described. In both patients laboratory findings suggested an underlying haematological disorder and bone marrow biopsy showed a myeloproliferative disorder. Both chronic cerebral venous thrombosis and early myeloproliferative disorders are difficult to diagnose. Their combined occurrence may be less rare than is frequently supposed.
متن کاملClinical applications of molecular haematology: JAK2 in myeloproliferative disorders.
Molecular markers are helpful in diagnosis, prognosis and management of haematological malignancies. Recently, a single point mutation in the Janus Kinase 2 (JAK2) gene in the Philadelphia-negative myeloproliferative disorders, including polycythemia vera (over 95%), essential thrombocythemia (50%) and primary myelofibrosis (50%) was identified by several groups. This mutation is now considered...
