  ABSTRACT: Extranodal natural killer/T-cell lymphoma (ENKL), a subtype of natural killer/T-cell malignancies, is a rare subset of lymphomas with significant biological and clinical heterogeneity. The prognosis of ENKL is variable and therapeutic approaches are not well established. The optimal dose, combination, and sequence of radiotherapy and chemotherapy are evolving, as is the role of stem cell transplantation. Radiotherapy is an essential component of therapy for early-stage disease. The clinical course of advanced disease is highly aggressive, with frequent chemotherapy resistance and a poor prognosis. For relapsed disease, asparaginase-based regimens have provided encouraging results and are currently under investigation in the frontline setting. Our article discusses the key aspects of biology, pathogenesis and clinical presentation that contribute to the heterogeneity, and proposes a stratified approach to the treatment of ENKL based on clinical, pathologic and biologic risk factors. Although considerable advances have been made in our understanding of the biology and prognosis of this lymphoma, it remains critical that all patients with a diagnosis of ENKL are enrolled and treated in clinical trials so that optimal therapies can be identified.

• Article: Targeting CD40 in Waldenström's macroglobulinemia.

  ABSTRACT: CD40 is a member of the tumor necrosis factor (TNF) receptor family and is expressed in a majority of B-cell malignancies. In Waldenström's macroglobulinemia (WM), CD40 expression is a common feature of bone marrow infiltrating lymphoplasmacytic cells, and preclinical evidence suggests that CD40 signaling is functionally important for WM growth and survival. Two antibodies targeting CD40 (SGN-40 and HCD 122 [Chir 12.12]) are currently undergoing clinical testing in multiple myeloma (MM) and non-Hodgkin lymphoma (NHL). HCD122 is a novel, fully human, IgG1 antagonistic monoclonal antibody while SGN-40 is a humanized IgG1 partial agonistic antibody. Both agents have demonstrated activity in preclinical models and are potent mediators of antibodydependent cellular cytotoxicity (ADCC). Clinically, phase I data suggest both agents are well tolerated with no immunogenicity and have early evidence of single-agent clinical activity in relapsed and refractory NHL and MM. These observations support the testing of CD40-targeted agents in WM.
