title: Rapid detection of lymphoma-specific translocations in interphase nuclei of non-Hodgkin's lymphoma by fluorescence in situ hybridization.
abstract: We have recently developed a method to detect tumor-specific rearrangement of the IgH gene in interphase nuclei by fluorescence in situ hybridization. Tumor-specific IgH gene rearrangement is equivalent to 14q32.33 translocation. Using this approach, we detected 14q32.33 translocation in 29 of 70 patients with B-cell non-Hodgkin's lymphoma (NHL). Chromosome t(3;14) was found in 10 of these 29 patients, and were demonstrated as a fusion signal of BCL6 and VH gene probes in interphase nuclei. Furthermore, in another series of 11 patients and a NHL cell line, we demonstrated t(14;18) and t(11;14) in interphase and metaphase cells with a combination of BCL2 (or PRAD1) with IgH gene probes. Interphase FISH with lymphoma-associated gene probes is a rapid procedure for cytogenetic diagnosis of B-cell NHL.
