AB Despite a common origin from mature lymphoid cells, non-Hodgkin
lymphomas (NHL) represent a surprisingly heterogeneous group of lymphoid
malignancies whose classification is continuously being remodeled. The
most recent proposal, the Revised European-American classification,
introduces pathogenetic features among the classification criteria. In
this respect, knowledge of the molecular pathogenesis of NHL, which is
based upon genetic lesions leading to activation of proto-oncogenes
(e.g. BCL-1, BCL-2, BCL-6, c-MYC) or disruption of tumor suppressor
genes (e.g. p53), is becoming increasingly relevant for the clinician.
These lesions combine into multiple molecular pathways which are
selectively associated with distinct NHL types. Thus, for example,
rearrangements of BCL-1, BCL-2, BCL-6, and c-MYC ar the genetic
hallmarks of mantle cell, follicular, diffuse large cell, and Burkitt's
lymphoma, respectively. Overall, from clinical perspective, NHL genetic
lesions serve three purposes: a) they assist and complement histologic
diagnosis; b) they provide a molecular marker with prognostic relevance;
c) they allow evaluation of minimal residual disease through highly
specific and highly sensitive technologies.
