Diffuse large B-cell lymphoma: Insights gained from gene expression profiling

Analysis of global gene expression with DNA microarrays has great potential to improve the understanding of tumorigenesis, advance tumor diagnosis and classification, and affect cancer treatment. Diffuse large B-cell lymphoma (DLBCL) is the most common type of non-Hodgkin's lymphoma. However, we now realize that the disease is extremely heterogeneous. This review summarizes the progress in understanding DLBCL that has been made as a result of the application of gene expression profiling. (C)2003 The Japanese Society of Hematology.
