PG - 102-7 AB - We characterized a t(3;14)(q27;q32) translocation in nine patients with B-cell, non-Hodgkin lymphoma (B-NHL) by fluorescence in situ hybridization (FISH). Fluorescence in situ hybridization with immunoglobulin heavy chain (IgH) and BCL6 gene probes detected t(3;14) rapidly and accurately, including complex t(3;14) in three patients; one with t(3;12;8;14)(q27;p13;q24.1;q32) and two with t(3;?;14)(q27;?;q32). Among these nine patients, seven escaped from cytogenetic detection by our G-banding analysis. Double-color FISH with IgH (Y6) and BCL6 (cosB5-1) showed fusion of BCL6 and IgH genes on der(3)t(3;14) in all nine patients, suggesting that der(3) may play a critical role in the development of lymphoma carrying complex as well as standard t(3;14) translocations. BCL6/IgH fusion gene was also demonstrated in interphase nuclei at a frequency of 23% to 91.5% over the cut-off value in control studies (9.0 +/- 2.76%). The breakpoints assessed by FISH with two cosmid clones containing BCL6 probes, cosB5-1 and cosB5-2, were within the cluster region in seven patients including one with complex type, but were not evaluated in two patients with t(3;?;14), because of the loss of partner chromosome. Using double-color FISH with these two BCL6-specific probes, none of an additional 32 patients in whom mitotic spreads were available showed 3q27 translocations. Fluorescence in situ hybridization with IgH and BCL6 gene probes is a rapid and sensitive method to detect t(3;14) in routine cytogenetic studies.
