BACKGROUND This study evaluates the specificity of some reverse-transcriptase polymerase chain reaction (RT-PCR) assays for the detection of residual tumor cells in breast cancer patients. The following markers have been analysed: carcinoembryonic antigen (CEA), cytokeratins (CK19 and CK20), polymorphic epithelial mucin (MUC-1), epidermal growth factor(More)
Based on preliminary encouraging results in terms of response rate and survival, high-dose chemoradiotherapy has gained considerable interest in the treatment of patients with multiple myeloma (MM). We have evaluated the presence of residual myeloma cells in 15 of 18 patients enrolled in a high-dose sequential (HDS) chemoradiotherapy program followed by(More)
Some evidences suggest that telomere restriction fragment length (TRF-L) is an effective indicator of histopathogenesis in B-cell tumors. As histopathogenesis is relevant for B-cell chronic lymphocytic leukemia (B-CLL) prognosis, TRF-L was assessed by Southern blot in 201 patients and compared to variable immunoglobulin heave chain gene mutational status(More)
Minimal residual disease (MRD) was evaluated in 30 patients with follicular or mantle cell non-Hodgkin's lymphoma (NHL) undergoing an intensive treatment with high-dose sequential (HDS) chemotherapy and peripheral blood progenitor cell (PBPC) autografting. To minimize the potential tumor cell contamination, PBPC harvests were scheduled at the end of HDS(More)
Cyclooxygenase 2 (COX-2) is an inflammation-associated enzyme involved in the pathogenesis of many solid tumors, but little is known about its presence and role in hematologic neoplasms. Multiple myeloma (MM) is known to involve a deregulated cytokine network with secretion of inflammatory mediators. We thus decided to investigate the involvement of COX-2(More)
The aim of this study was to investigate feasibility, tolerability and efficacy of rituximab-supplemented high-dose sequential chemotherapy (R-HDS) with peripheral blood progenitor cell autografting as frontline or salvage treatment in patients with advanced non-Hodgkin's lymphoma (NHL). Thirty-two patients have been treated: 14 at disease onset and 18 with(More)
Multiple myeloma (MM) is characterized by the expansion of terminally differentiated plasma cells. It is still uncertain whether the clonogenic fraction is confined to the plasma cell or pre-plasma cell compartment. We examined the immunoglobulin (Ig) rearrangement of myeloma heavily infiltrated bone marrow cells with a probe from the heavy chain J region(More)
Development of a second lymphoma after autotransplantation is an unusual event. Its real incidence, however, could be underestimated, since histologic and immunophenotyping techniques are often unable to distinguish it from a relapse. We report a lymphoma patient in apparent relapse after 42 months of molecular remission achieved by autotransplantation.(More)
BACKGROUND Multiple Myeloma (MM) is a neoplastic disorder characterized by clonal proliferation of malignant plasma cells (PCs). Flow cytometry is an essential tool to confirm diagnosis and evaluate minimal residual disease (MRD). This study aims at identifying new surface PC markers suitable for targeted therapy in MM and able to improve MRD detection. (More)
PURPOSE To assess whether nonneoplastic Bcl-2/IgH rearrangements act as a confounding factor in the setting of minimal residual disease analysis by evaluating their incidence in a panel of lymphoma-free subjects, including cancer-free donors and chemotherapy-naive and chemotherapy-treated cancer patients. PATIENTS AND METHODS A total of 501 nonlymphoma(More)
