UNLABELLED Primary breast lymphoma (PBL) is a rare disease accounting for 0.4-0.5% of all breast malignancies. Diffuse large B-cell lymphoma (DLBCL) is the most common histological diagnosis. The clinical presentation of PBLs is usually no different from that of carcinoma. In this paper we review the literature on the clinical presentation, diagnosis, prognostic factors and treatment options of...
PURPOSE In patients with acute leukemias, a lymphoid phenotype, the presence of a Philadelphia chromosome (Ph), and inadequate central nervous system (CNS)-directed prophylactic therapy are risk factors for CNS involvement. Imatinib mesylate has promising single-agent antileukemic activity in patients with advanced Ph(+) acute leukemias. It was the aim of this analysis to determine the incidenc...
Background: Central nervous system (CNS) relapse still represents an often-fatal event in diffuse large B cell lymphoma (DLBCL). Efforts to prevent it aimed identify higher risk patients and administer adequate prophylaxis. In this setting, unmet needs such as the type of prophylaxis (high-dose methotrexate, HD-MTX vs. triple intrathecal therapy) its timing are under debate. Hereby, we report o...
Background: Acute lymphoblastic leukemia (ALL) affects both children and adults, with a peak incidence between the ages of 2 and 5 years. ALL cells sometimes penetrate the central nervous system (CNS) and patients with CNS diseases at initial presentation have been reported to experience a significantly greater risk of treatment failure compared with CNS negative patients. This study hypothesiz...
Abstract Central nervous system (CNS) involvement remains a challenge in the diagnosis and treatment of acute lymphoblastic leukemia (ALL). In this study, we identify CD79a (also known as Ig?), signaling component preB cell receptor (preBCR), to be associated with CNS-infiltration –relapse B-cell precursor (BCP)-ALL patients. Furthermore, show that downregulation hampers engraftment cells diffe...
OBJECTIVES To assess the incidence of isolated central nervous system (CNS) relapses in patients of acute lymphoblastic leukemia (ALL) treated with a protocol containing cranial irradiation and intrathecal methotrexate as CNS directed therapy. DESIGN Prospective non randomized study. SETTING Department of Medical Oncology, Tata Memorial Hospital. SUBJECTS 623 children of ALL on MCP 841. ...
The records of 415 patients who received allogeneic marrow transplants for acute leukemia were reviewed to assess the risk of central nervous system (CNS) relapse and leukoencephalopathy after marrow transplantation. The Kaplan-Meier estimates of the probability of CNS relapse posttransplant were 13% for patients with acute lymphoblastic leukemia (ALL) and 2% for patients with acute nonlymphobl...
Presymptomatic central nervous system (CNS) treatment in children with a late isolated first bone marrow (BM) relapse of acute lymphoblastic leukemia (ALL) was based on intermediate-dose systemic and intrathecal (IT) methotrexate (MTX) in the multicenter trial, ALL-REZ BFM 85. Because this was associated with an excess of overt second CNS relapses, cranial radiotherapy (cRT) plus prolonged trip...
