MicroRNAs (miRNAs) are negative regulators of expression of genes involved in hematopoiesis. The present study sought to link hematopoiesis-relevant miRNAs with myelodysplastic syndromes (MDS) and MDS progression to acute myeloid leukemia (AML). We assessed 25 mature miRNAs in total RNA from bone marrow (BM) and peripheral blood (PB) of 25 newly diagnosed(More)
BACKGROUND Survival of patients with primary central nervous system lymphoma (PCNSL) has improved with methotrexate-based combination regimens and radiotherapy (RT). However, the prognosis of patients who fail or relapse after initial response is poor. Very little data is available on salvage treatment at recurrence. PATIENTS AND METHODS Sixteen(More)
The benefit of azacitidine treatment in survival of high-risk myelodysplastic syndromes (MDS) patients compared with conventional care treatment (CCT) has not been established outside clinical trials. To assess its effectiveness, we compared overall survival (OS) between azacitidine and conventional treatment (CCT) in high-risk MDS patients, excluding those(More)
T-cell prolymphocytic leukemia (T-PLL) is a chemotherapy-resistant malignancy with a median survival of 7.5 months. Preliminary results indicated a high remission induction rate with the human CD52 antibody, CAMPATH-1H. This study reports results in 39 patients with T-PLL treated with CAMPATH-1H between March 1993 and May 2000. All but 2 patients had(More)
PURPOSE To assess the effect of a reduced dose of radiotherapy (RT) in patients with primary CNS lymphoma (PCNSL) responding to the cyclophosphamide, doxorubicin, vincristine, and dexamethasone (CHOD)/carmustine, vincristine, methotrexate, and cytarabine (BVAM) regimen. PATIENTS AND METHODS Patients received one cycle of CHOD and two of BVAM. In the first(More)
The aim of this study was to analyse the effect of glucocorticoid therapy (GCCT) on Wnt signalling antagonists (sclerostin and Dkk-1) and their relationship with bone turnover. 25 patients (8 M/17 F, aged 48±19yrs) recently initiating GCCT (≥7.5mg/day, ≤6months) were prospectively included. Bone turnover markers (bone formation: P1NP, osteocalcin [OC], bone(More)
The natural course of chronic myelomonocytic leukemia (CMML) is highly variable but a widely accepted prognostic scoring system for patients with CMML is not available. The main aim of this study was to develop a new CMML-specific prognostic scoring system (CPSS) in a large series of 558 patients with CMML (training cohort, Spanish Group of Myelodysplastic(More)
Transfusion-dependency is associated with poor prognosis in patients with MDS although the causal link for such association is disputed. This study tests thee hypotheses on the association between transfusion burden and prognosis in the MDS: (1) the cumulative transfusion burden is a confounder merely reflecting the time elapsed from diagnosis; (2) it is a(More)
T-cell prolymphocytic leukemia (T-PLL) is a rare postthymic T-cell disorder that may show different morphologic variants and a very aggressive clinical behavior. On occasion, patients may present with an indolent clinical course and long survival. The disease is genetically characterized by the presence of complex karyotypes with recurrent alterations(More)
BACKGROUND Different prognostic scores have been proposed to predict the outcome of follicular lymphoma (FL) patients at diagnosis. A new prognostic index specifically addressing FL patients, the Follicular Lymphoma International Prognostic Index (FLIPI), has recently been developed, which might also be useful in patients with progression.
