In a retrospective study of 236 patients with primary myelodysplastic syndromes (MDS), 130 cases (55.1%) revealed myelofibrosis in bone marrow biopsies. It was observed that fibrosis mostly occurs focally or patchy, and collagen deposits were found very rarely (only four patients). The histopathology of bone marrow biopsies revealed several differences between fibrotic and non-fibrotic MDS: cellularity is significantly higher, dysmegakaryopoiesis is more pronounced, plasmocytes and mast cells are more often increased, and disturbance of marrow topography (particularly of the MK- and G-line) can be found more frequently in MDS with myelofibrosis. Reticulin fibrosis occurred in all subtypes of MDS; however, there was a higher incidence in chronic myelomonocytic leukemia. The frequency of abnormal growth of GM-progenitors was significantly higher in the MDS cases with myelofibrosis, compared to the cases without fibrosis. Clinical data showed significantly higher WBC, more frequent presence of immature granulocytes, and higher percentage of myeloblasts in peripheral blood and bone marrow in MDS with myelofibrosis compared to cases without myelofibrosis. Life expectancy was reduced to 13 mo, compared with 35 mo in MDS without fibrosis (p=0.00055). Time to leukemic transformation was 32 mo in MDS with fibrosis, compared with >56 mo in MDS without fibrosis (p=0.015). Myelofibrosis therefore seems to herald a poor prognosis.  相似文献

Primary myelofibrosis (PMF) is myeloproliferative neoplasm whose diagnosis is based on a combination of clinical and pathology criteria. We evaluated 560 consecutive patients who were diagnosed with PMF upon a referral to our center and evaluated the frequency of and reasons for diagnostic discordance. Discordance in the diagnosis was found in 70 (12.5%) patients. Discordant cases had a significantly lower grade of bone marrow fibrosis (grade 0–1), more likely to be JAK2V617F-mutation negative, and have no peripheral blood blasts, possibly explaining the difficulty in making a proper diagnosis and underscoring the need for a complete evaluation at a tertiary center.  相似文献

CML is often associated with myelofibrosis, and fibrosis in the accelerated phase is one of the diagnostic criteria for this accelerated phase. In this review, the mechanism of myelofibrosis associated with CML is discussed with emphasis on the cell origin of the production and release of platelet derived growth factor (PDCF) and its interaction with marrow fibroblasts. In the initial stage of myelofibrosis in chronic phase CML, atypical small megakaryocytes might leak PDGF, possibly PDGF-AB, together with other growth factors. As the clinical phase of the disease progreses to accelerated or blastic phase, a larger quantity of PDGF-AB or PDGF-BB might be secreted from blastic cells with myeloid phenotype. In addition some fibroblasts may be attracted by the PDGF and proliferate, and deposit collagen as well as fibronectin in the bone marrow stroma.  相似文献

The relationship between fibrosis and megakaryocytic infiltration in the lungs of patients with Philadelphia-chromosome (Ph1)-positive chronic myelogenous leukemia (CML) is the focus of this review. Ph1-positive megakaryocytes are thought to reach and accumulate in the pulmonary vasculature through the marrow-blood barrier. In 21 autopsied patients with accelerated phase or blastic crisis of CML, megakaryocytic infiltration to the lungs was demonstrated in 10 patients, myelofibrosis in 12 patients and both in 5 patients. In 2 of the 10 patients with increased megakaryocytes in the lungs, relatively new fibrosis and alveolar damage in the acute phase were demonstrated with the simultaneous occurrence of myelofibrosis-“myelopulmonary fibrosis.” Leakage of mitogenic factors resulting from an abnormality in the packaging mechanism of alpha-granules in these cells termed acquired grey platelet syndrome could cause Fibrosis in the lungs as well as the bone marrow.  相似文献

Although collagen myelofibrosis indicates poor prognosis in late stages of chronic myelogenous leukemia, the significance of reticulin stain-measured fibrosis in newly diagnosed patients is unknown. One hundred and thirty-eight patients with untreated or minimally treated chronic phase Philadelphia chromosome-positive chronic myelogenous leukemia had reticulin stain studies made on their bone marrows at diagnosis. Reticulin fibrosis was graded on a scale of 1 to 4. Significant (Grade 3 or 4) fibrosis was noted in 65 patients (47%). Compared with patients with mild (Grade 1 to 2) reticulin fibrosis, those with significant fibrosis had a higher incidence of splenomegaly greater than or equal to 10 cm (29% versus 49%; P = 0.02), hemoglobin less than 10 g/dl (19% versus 49%; P less than 0.01), weight loss greater than or equal to 6.75 kg (10% versus 30%; P = 0.11), marrow blasts greater than or equal to 5% (7% versus 28%; P less than 0.01), peripheral blasts greater than or equal to 3% (30% versus 46%; P = 0.09), and additional karyotypic abnormalities (1% versus 17%; P less than 0.01). The incidence of thrombocytosis was similar in the two groups. Prognostically, median survival was significantly shorter for the 26 patients with Grade 4, compared with the 39 patients with Grade 3, and the 73 patients with Grade 1 or 2 reticulin fibrosis (32 versus 49 versus 57 months; P = 0.03). Reticulin fibrosis is a useful biologic and prognostic index in newly diagnosed patients with chronic phase chronic myelogenous leukemia.  相似文献

Acute myelofibrosis is a rare but distinct accelerated variant of agnogenic myeloid metaplasia that is characterized by marked anemia, peripheral blood myeloblastosis and normoblastosis, a lack of teardrop poikilocytosis, and prominent myelofibrosis. There is usually no palpable hepatosplenomegaly or lymph node enlargement. The clinical course is remarkable short. We describe a 63-year-old man who presented with idiopathic acquired sideroblastic anemia and subsequently developed acute myelofibrosis. Intensive polychemotherapy with vincristine, cytosine arabinoside, and prednisone and a later trial of oxymetholone therapy were ineffective. He died 134 days after the diagnosis of acute myelofibrosis was established. The 11 previously reported cases of acute myelofibrosis are reviewed, and the relationships of acute myelofibrosis to other myeloproliferative disorders and to idiopathic acquired sideroblastic anemia are discussed.  相似文献

We analyzed cytogenetic data at diagnosis in 395 primary myelofibrosis (PMF) patients to evaluate any possible association between karyotype and WHO 2017 classification and its impact on prognosis. All the cases were diagnosed and followed at five Italian Hematological Centers between November 1983 and December 2016. An abnormal karyotype (AK) was found in 69 patients and clustered differently according to bone marrow fibrosis grade as it was found in 31 (27.0%) cases with overt fibrotic and 38 (13.6%) with pre‐fibrotic PMF (p = 0.001). Sex, anemia, thrombocytopenia, circulating blasts ≥1%, higher lactate dehydrogenase, and International Prognostic Scoring System risk classes were all significantly associated with karyotype. At a median follow‐up of >6 years, 101 deaths were recorded. Survival was different between AK and normal karyotype (NK) patients with an estimated median overall survival (OS) of 11.6 and 25.7 years, respectively (p = 0.0148). In conclusion, in our cohort around 20% of patients had an AK, more frequently in subjects with an advanced bone marrow fibrosis grade and clinical‐laboratory features indicative of a more aggressive disease. This study shows that an AK confers a more severe clinical phenotype and impacts adversely on OS, thus representing an additional parameter to be considered in the evaluation of PMF prognosis.  相似文献

Agnogenic myeloid metaplasia (AMM) is a chronic myeloproliferative disorder that leads to a sustained proliferation of megakaryocytes and an increase of reticulin fibers within the bone marrow. Blood and bone marrow samples from patients with advanced AMM with fully developed myelofibrosis as well as cases in the cellular phase of the disease were investigated for clonality. Clonality was studied by X-linked restriction length polymorphism in conjunction with DNA methylation patterns. Granulocytes and total bone marrow cells proved to be monoclonal in origin whereas at least a minor portion of the peripheral lymphocytes were not clonally derived. Our findings indicate that the cellular phase of AMM as well as the fully developed disease progressed to myelofibrosis represent a monoclonal proliferation of pluripotent hematopoietic stem cells.  相似文献
