Drs. Baidas, Cheson, Kauh, and Ozdemirli present a thorough and balanced review of mantle cell lymphoma (MCL) and the various current treatment options. MCL has been recognized as a distinct pathologic entity for over a decade. It represents 6% to 9% of all non- Hodgkin’s lymphoma cases, and the diagnosis is based on a combination of morphologic, immunophenotypic, and cytogenetic criteria as discussed in the article. The hallmark of MCL is t(11;14)(q13;q32), a translocation that juxtaposes the Bcl-1 gene on chromosome 11 and immunoglobulin (Ig)H promoter on chromosome 14, leading to overexpression of cyclin D1. Although it had been considered an indolent lymphoma for many years, MCL has a poor prognosis with short remissions and a median survival of 3 to 4 years.[1,2]
