Clinical significance of gene defects in B-cell lymphomas.

Abstract

Lymphomas are a heterogenous group of malignant diseases. Identification of sub-groups has created pressure for a more detailed diagnosis and individualized treatment. Although the underlying genetic and molecular pathologic factors of the most common B-cell derived lymphomas, i.e. diffuse large B-cell lymphoma and follicular lymphoma, have become more accurate, prognosis is evaluated and treatment options still selected mainly on the basis of clinical variables. In the future, new generation sequencing methods that are becoming more common in clinical practice will allow the assessment of prognosis and treatment on the basis of biologic and genetic risk factors. To achieve this both comprehensive basic research and clinical drug trials taking the pathogenesis of different diseases into consideration are required.
