BACKGROUND AND OBJECTIVE Central nervous system (CNS) involvement in patients diagnosed with acute leukemias (AL) is an uncommon complication with poor prognosis. The indication and the schedules of prophylaxis and treatment of CNS involvement in AL are not homogenous among countries and within the same country. The aim of this prospective longitudinal study was to analyze and report the practi...
Central nervous system (CNS) relapse is an uncommon devastating complication of diffuse large B-cell lymphoma (DLBCL) that usually occurs within 2 years from initial diagnosis. Its pathophysiology is poorly understood and there is no consensus on the definition of high-risk patients for CNS relapse. Consequently, an empirical and highly variable practice of chemoprophylaxis is employed. In this...
BACKGROUND Central nervous system (CNS) relapse is an uncommon but dramatic complication of diffuse large B-cell lymphoma (DLBCL). Several studies have demonstrated the superiority of cerebrospinal fluid (CSF) flow cytometry (FCM), as compared with conventional cytology (CC), in detecting occult leptomeningeal disease. The clinical relevance of a positive FCM still has to be clarified. PATIEN...
The central nervous system (CNS) is one of the most frequent extramedullary locations of adult acute lymphoblastic leukemia (ALL), affecting approximately 5% of patients at diagnosis. T-lineage ALL, high initial leukocyte counts and mediastinal involvement are the predisposing factors. In case of relapse, if no prophylaxis was administered, the rate of CNS involvement reaches 30-50%. As the pro...
In the five Nordic countries, 808 children 1 to 15 years of age (428 boys, 380 girls) were diagnosed with non-B acute lymphoblastic leukemia (ALL) from July 1981 through June 1986. Complete remission was achieved in 770 children (95%). Central nervous system (CNS) involvement at diagnosis was noticed in 34 children, of whom 26 achieved remission. Of these 26 patients 11 subsequently relapsed, 5...
Although major progress has been made in the treatment of childhood leukemia, the optimal chemotherapy of acute lymphoblastic leukemia (ALL) in adults has been unclear. In addition, the value of central nervous system prophylaxis (CNS-P) in adults has been assumed, but not established in a systematic fashion. The Southeastern Cancer Study Group has completed a prospective study in which the use...
BACKGROUND To describe incidence, risk factors, and influence of treatment on occurrence of central nervous system (CNS) relapse or progression in younger patients with aggressive B-cell lymphoma. PATIENTS AND METHODS We analyzed 2210 patients with aggressive B-cell lymphoma treated on various studies for CNS relapse/progression. Treatment consisted of CHOP (cyclophosphamide, doxorubicin, vin...
Introduction: Primary breast lymphoma (PBL) is a rare form of extranodal lymphoma. The most common pathology diffuse large B cell and patients are diagnosed at stages 1 2. therapeutic options available so far include surgery, radiotherapy, chemotherapy Case Presentation: patient was 54-year old woman with localized primary B-cell (DLBCL). underwent 6 courses an R-CHOP regimen followed by radiot...
Central nervous system (CNS) lymphomatosis is a fatal complication of aggressive non-Hodgkin lymphoma (NHL). In lymphoblastic or Burkitt lymphoma, without specific CNS prophylaxis the risk of CNS relapse is 20-30%. DLBCL has a lower risk of relapse (around 5%) but several factors increase its incidence. There is no consensus or trials to conclude which is the best CNS prophylaxis. Best results ...
We performed a retrospective analysis to identify risk factors and survival outcome for central nervous system (CNS) relapse of peripheral T-cell lymphoma (PTCL) by histologic type. Records of 600 PTCL patients diagnosed between 1999 and 2014 were analyzed including PTCL not otherwise specified (PTCL-NOS, 174 patients), angoimmunoblastic T-cell lymphoma (AITL, 144), ALK+anaplastic large cell ly...
