title: Immunophenotypic and molecular studies in the diagnosis and classification of malignant lymphoma.
abstract: Immunophenotypic and molecular studies play an increasingly important role in the diagnosis and classification of lymphoid neoplasms. These studies are not yet a substitute for expert histopathologic evaluation, but are a valuable adjunct to the examination of the hematoxylin and eosin-stained slide. Major applications include determination of lineage, determination of B and T cell monoclonality, detection of oncoprotein expression, and detection of oncogene rearrangements and chromosomal translocations. The recognition of the lymphomas as distinct biologic entities with specific immunophenotypic and genotypic features, as embodied in the Revised European-American Lymphoma (REAL) and World Health Organization (WHO) classifications, is a key to the future development and application of targeted biologic and molecular therapies. In the future, application of gene expression array analysis to the lymphoid neoplasms will permit classification of the lymphomas at a molecular level.
