This study aims to analyze the expression of 14 cancer/testis (CT) antigens in multiple myeloma (MM) to identify possible prognostic markers and therapeutic targets. The expression of MAGEA1, MAGEA2, MAGEA3/6, MAGEA4, MAGEA10, MAGEA12, BAGE1, MAGEC1/CT7, the GAGE family, LAGE-1, PRAME, NY-ESO-1, SPA17 and SSX1 was studied by RT-PCR in 15 normal tissues, a(More)
The purpose of this study is to correlate the presence of TP53 gene mutations with the clinical outcome of a cohort of patients with diffuse large B-cell lymphoma (DLBCL) assembled from 12 medical centers. TP53 mutations were identified in 102 of 477 patients, and the overall survival (OS) of patients with TP53 mutations was significantly worse than those(More)
We reported seven cases (0.7%) of PTLD among 1002 renal transplants performed at Renal Transplant Service from Hospital São Paulo-Universidade Federal de São Paulo/Escola Paulista de Medicina, São Paulo, Brazil, between 1976 and 1997. There were three male and four female patients with median age of 37 year-old. According to Ann Arbor staging system there(More)
Methylation of p16 gene is a relatively frequent molecular finding in multiple myeloma (MM), but its clinical implication is disputable. Cell cycle regulators are now recognized as active in the control of angiogenesis, which is an integral component of pathogenesis and a target for new treatment modalities of this disease. On such background, we focused on(More)
OBJECTIVES Vascular endothelial growth factor (VEGF) acts in several steps of multiple myeloma (MM) pathogenesis and it is an important mediator of tumor angiogenesis. The aim of this study was to examine the prognostic significance of VEGF immunoexpression in the context of standard prognostic factors present in a cohort of advanced MM patients. METHODS(More)
It is well established that interleukin-6 (IL-6) is an essential growth factor for multiple myeloma (MM) and patients with increased IL-6 levels have a poor prognosis. In healthy subjects, the presence of the C allele at a polymorphic site (-174 G/C) of the IL-6 gene is related to low IL-6 levels. In view of the potential association of this particular(More)
Multiple myeloma (MM) is an incurable hematological malignancy. Different studies demonstrated the occurrence of genetic and epigenetic alterations in MM. The aberrant methylation is one of the most frequent epigenetic alterations in human genome. This study evaluated the aberrant methylation status of 20 genes in 51 MM samples by quantitative(More)
Twenty cases of systemic non-Hodgkin's lymphoma (NHL) in HIV-infected patients were reviewed over a 10-year-period, divided into Group A, including 13 NHL cases treated before the highly active antiretroviral therapy (HAART) era, and Group B, including 7 patients who received HAART. A Kaplan-Meier survival curve was performed and log-rank was applied to(More)
Primary malignant breast lymphoma (PBL) is a rare disease with an incidence of 0.04-0.5% of all malignant breast neoplasms. The majority of cases are B-cell lymphomas and the most common histologic type is diffuse large B-cell lymphoma (DLCL). In this study, we report our experience with three cases of PBL. The treatment was the same currently indicated for(More)
