The clinical efficacy of evaluating genetic anomalies in metaphase cells versus interphase nuclei for multiple myeloma (MM) is poorly understood. Therefore, survival for 154 patients with newly diagnosed untreated MM was compared with results from analysis of metaphase and interphase cells. Metaphases were studied by conventional cytogenetics and fluorescent-labeled DNA probes (fluorescence in ...
Gene activation by translocation between an oncogene and an immunoglobulin heavy-chain gene, which leads to increased expression of the oncoprotein, is a well-known mechanism in the genesis of B-cell lymphomas. In contrast, the role of gene amplification in activation of oncogenes in non-Hodgkin's lymphomas is poorly characterized. To study the BCL2 amplification we performed comparative genomi...
BACKGROUND AND OBJECTIVES Splenic marginal zone B-cell lymphoma (SMZBCL) has clinical, immunophenotypic and histologic features distinct from other B-cell malignancies, but few chromosome studies have been previously reported. In the present study we performed conventional cytogenetics and in situ hybridization studies in 47 patients with SMZBCL. DESIGN AND METHODS We studied 47 cases of sple...
Chromosomal rearrangements involving the immunoglobulin heavy chain gene (IGH) at 14q32 are observed in approximately 50% of patients with B-cell non-Hodgkin's lymphoma (NHL). The 5' end of the IGH gene is located within 8 kb of the telomeric repeats of 14q. Translocations involving the IGH locus and the telomeric band of a partner chromosome are difficult to identify, because most terminal ban...
