Mantle cell lymphoma (MCL) represents a distinct lymphoma subtype. The prognosis of patients with MCL is the poorest among lymphoma patients and the response to conventional treatments is inadequate. New approaches targeted to the biology of MCL and the genetics underlying the disease are being studied. Monoclonal antibodies directed at molecules expressed on MCL cells are already used in the clinical setting. This article reviews the literature on these and other new possible treatment modalities.
