Marginal zone lymphomas (MZL) are a heterogeneous subtype of indolent B-non-Hodgkin lymphomas that includes distinct entities:

  • Extranodal mucosa-associated lymphoid tissue lymphoma arises in a variety of tissue but primarily in the stomach. They are usually localised and often associated with chronic antigenic stimulation by microbial pathogens. Eradication of the pathogen is a major part of the first-line therapy. The prognosis is excellent in early stages. In advanced stages, observation, anti-CD20 antibodies and/or cytostatic drugs are therapeutical approaches.
  • Nodal MZL is usually confined in lymph nodes, bone marrow and peripheral blood. The prognosis is somewhat worse in this entity. Current recommendations suggest that they should be managed as follicular lymphomas.
  • Splenic MZL is a unique entity involving the spleen, bone marrow and blood. Hepatitis infection should be eradicated before considering treatment. These lymphomas have an indolent behaviour, and only symptomatic patients should be treated by splenectomy and/or anti-CD20 antibodies.
  • Two novel entities are described, non-chronic lymphocytic leukaemia monoclonal B-cell lymphocytosis, probably closely related to splenic MZL lymphoma, and a less well-defined provisional entity involving primarily the spleen called splenic B-cell lymphoma/leukaemia, unclassifiable, including splenic diffuse red pulp lymphoma and hairy-cell leukaemia variant.

This review will discuss separately the diagnosis, work-up and treatment of extranodal mucosa-associated lymphoid tissue lymphoma, nodal MZL and splenic MZL. These guidelines include the recently published ESMO consensus conference on malignant lymphoma.1–3

BHS guidelines for the treatment of large granular lymphocyte and chronic prolymphocytic leukaemias

BJH - volume 7, issue 3, june 2016

C. Springael MD, PhD, V. Delrieu MD, K.L. Wu MD, PhD, W. Schroyens MD, PhD, C. Bonnet MD, D. Bron MD, PhD, A. Janssens MD, PhD, On behalf of the BHS Lymphoproliferative Working Party

Summary

Large granular lymphocyte and prolymphocytic leukaemias are rare chronic lymphoproliferative disorders. Large granular lymphocyte leukaemias consist of indolent disorders such as T-cell large granular lymphocyte and chronic lymphoproliferative disorder of natural killer cells and the very rare but aggressive natural killer cell leukaemia. Treatment of the indolent large granular lymphocyte leukaemias is necessary in case of symptomatic cytopaenias or non-haematological autoimmune disorders. First line therapy of these two disorders is based on three immunosuppressive drugs: methotrexate, cyclophosphamide and cyclosporine A. Aggressive natural killer cell leukaemia needs an L-asparaginase containing regimen as induction followed by allogeneic stem cell transplantation to prolong remission. T-cell prolymphocytic leukaemia always follows an aggressive course even after an indolent onset. The optimal treatment strategy should exist of remission induction with alemtuzumab intravenously followed by autologous or allogeneic stem cell transplantation. Treatment indications for B-cell prolymphocytic leukaemia follow the criteria described by the chronic lymphocytic leukaemia guidelines. After induction with fludarabine, cyclophosphamide, rituximab or bendamustine in patients without a p53 mutation and/or a 17p deletion and alemtuzumab in case of a p53 mutation and/or a 17p deletion, stem cell transplantation must be considered.

BHS guidelines for primary central nervous system lymphoma

BJH - volume 7, issue 2, april 2016

V. De Wilde MD, PhD, D. Dierickx MD, PhD, W. Schroyens MD, PhD, E. Van den Neste MD, PhD, C. Bonnet MD, M. André MD, PhD, A. Janssens MD, PhD, V. Van Hende MD, A. Van Hoof MD, PhD

Summary

Primary central nervous system lymphoma is a rare form of extranodal B cell lymphoma of the brain, the eyes, the meninges or the spinal cord in the absence of systemic lymphoma. The management of primary central nervous system lymphoma remains controversial, which is related to the rarity of the cases and the small number of controlled studies available. The present consensus report provides the guidelines proposed by the Belgian Hematology Society Lymphoproliferative Working Party for treating immunocompetent adult patients with primary central nervous system lymphoma.
