Background/purpose

Diffuse large B-cell lymphoma (DLBCL) is the most common lymphoma type. The immunophenotypic and genetic features of DLBCL in Taiwan have not been characterized.

Methods

In this study, we performed immunohistochemical analysis and interphase fluorescence in situ hybridization (FISH) using tissue microarray sections to investigate a cohort of unselected DLBCL cases in a single institution in Taiwan from 1990 to 2010.

Results

Of the 153 cases investigated, CD10, bcl-6, and MUM1 were expressed in 16.3%, 71.2%, and 71.9% cases, respectively, with 27.5% (n = 42) of cases being classified as having a germinal center B-cell (GCB) origin by the Hans algorithm. By FISH analysis, 19.6%, 4.6%, 26.1%, and 3.9% cases showed rearrangement at IGH, BCL2, BCL6, and MYC loci, respectively, including three (2.0%) cases of double-hit lymphoma. As compared with the non-GCB tumors, GCB tumors more frequently expressed CD10 (p < 0.001) and bcl-6 (p = 0.001) with less frequent expression of MUM1 (p = 0.007). Moreover, GCB tumors more frequently exhibited rearrangement at the BCL2 (p = 0.024) and MYC (p = 0.038) loci than non-GCB tumors. However, there was no survival difference between these two groups.

Conclusion

In this first series of DLBCL evaluation from Taiwan, we found that the relative frequency of GCB tumors among DLBCL was low in most East Asian countries. There is a wide range of BCL2 rearrangement rates, higher in the West and lower in East Asia. A larger and/or national study is warranted to better understand the immunophenotypic and molecular features of DLBCL in Taiwan and their respective impact on patient survival."xsd:string
