This study was undertaken to evaluate the clinical significance of the expression of Bcl-2, p53 and LMP-1 in Hodgkin and Reed - Sternberg cells of patients with Hodgkin's lymphoma. The expression of these proteins in pre-treatment tissue biopsy specimens was correlated with presenting clinical features, failure-free survival (FFS) and overall survival (OS)(More)
Recent studies of gene expression and immunohistochemistry have shown that protein kinase C-beta II (PKC-beta II) might have prognostic significance in patients with diffuse large B-cell lymphoma (DLBCL). We sought to determine the prognostic significance of the expression of PKC-beta II in patients with nodal DLBCL. Formalin-fixed, paraffin-embedded(More)
Socioeconomic status (SES) is a determinant of outcome in various types of cancer. The aim of this study is to analyze the impact of the SES in Hodgkin's lymphoma (HL). From 2001 to 2005, 194 consecutive patients were prospectively followed in 5 institutions. Patients answered a questionnaire with a set of items used to determine the SES, and were then(More)
CONTEXT AND OBJECTIVE Free circulating Epstein-Barr virus (EBV) DNA is often present in the plasma of Hodgkins disease patients. The aim here was to evaluate the prevalence of this finding, its correlation with the immunohistochemical expression of LMP-1 (latent membrane protein 1) and the influence of other clinical factors. DESIGN AND SETTING(More)
The aim of this study was to assess the psychometric properties of the Brazilian Portuguese version of the “Medical Outcomes Study-Social Support Survey (MOS-SSS)” in Hodgkin's lymphoma (HL) survivors. The MOS-SSS is a 19-item questionnaire with five scales covering different aspects of social support (affection, positive social interaction, emotional,(More)
Plasmacytomas expressing immunoglobulin A are rare and not well characterized. In this study, 9 cases of IgA-positive plasmacytoma presenting in lymph node and 3 in extranodal sites were analyzed by morphology, immunohistochemistry, and polymerase chain reaction examination of immunoglobulin heavy and κ light chain genes. Laboratory features were correlated(More)
CONTEXT Fatigue is the most common symptom among Hodgkin's lymphoma survivors. OBJECTIVES To evaluate the psychometric properties of the Brazilian version of the Multidimensional Fatigue Inventory (MFI). METHODS The MFI was translated into Brazilian Portuguese using established forward-backward translation procedures, and the psychometric properties(More)
Diffuse large B cell lymphomas (DLCBL) are a group of lymphomas whose biologic and prognostic diversity has been recently well characterized. There is also morphologic heterogeneity, but the relevance of subclassification remains uncertain. The World Health Organization Classification states that pathologists have the choice to use only the term diffuse(More)
AIDS-related lymphomas (ARL) present high biological heterogeneity. For better characterization of this type of lymphoma, the objectives of the present study were to evaluate the expression of immunohistochemical markers of cell differentiation (CD10, Bcl-6, MUM-1) and determine cell origin profile according to Hans' classification of diffuse large B-cell(More)
The human germinal center-associated lymphoma (HGAL) gene has prognostic value in diffuse large B-cell lymphoma, and expression of its cognate protein is germinal center-specific. A previous study had suggested that HGAL protein expression might also be related to the outcome in patients with Hodgkin lymphoma (HL). The aim of this study was to confirm the(More)
