How could you select the best of the EHA meeting? A lot of teams presented very exciting work. In this overview I do not pretend to aim to summarise the entire meeting, I am simply reporting selected presentations, remarkable from my point of view.

BHS guidelines for the treatment of newly diagnosed diffuse large B-cell lymphoma (DLBCL) anno 2020

BJH - volume 11, issue 2, march 2020

Diffuse large B-cell lymphoma is the most common subtype of non-Hodgkin lymphoma. Prognosis of diffuse large B-cell lymphoma has improved dramatically since the introduction of rituximab and about two thirds of patients can be cured with immunochemotherapy. In the last twenty years, it became clear that diffuse large B-cell lymphoma is a very heterogeneous disease and based on the genetic mutation landscapes numerous efforts have been made to develop novel treatment strategies to improve the prognosis of diffuse large B-cell lymphoma further. This article provides an update of diagnosis, current treatment guidelines and novel treatment strategies for newly diagnosed patients with diffuse large B-cell lymphoma in Belgium. It will also focus on treatment of elderly patients and high-grade B-cell lymphoma.

Guidelines of the Belgian Hematological Society for newly diagnosed and relapsed follicular lymphoma anno 2019

Follicular lymphoma is the most common low-grade non-Hodgkin lymphoma. Survival rates have been rising over time mainly due to advancing therapeutic strategies. As the last Belgian guidelines date from 2012, we present an update of the scientific evidence regarding diagnosis, staging, treatment and follow-up, and confront these to the Belgian reimbursement rules anno 2019. Follicular lymphoma grade 3B is classified as high-grade lymphoma and treated accordingly, and will not be discussed in this paper. Early stage disease can be treated with involved-field radiotherapy, which has curative potential. Advanced stage disease is virtually incurable, but many treatment options are available with good results. In first line, treatment is mostly based on chemotherapy combined with rituximab; the latter can be continued as maintenance therapy. In relapsed setting, introduction of the newer and more potent anti-CD20-antibody obinutuzumab, also in combination with chemotherapy, can lead to improved survival in high-risk patients. For older patients with comorbidities, rituximab monotherapy is the preferred option. In further lines, PI3K-inhibition with idelalisib and radioimmunotherapy are available. Finally, autologous or allogeneic stem cell transplantation remain an option in a small group of selected patients.

BHS guidelines for the treatment of marginal zone lymphomas: 2018 update

BJH - volume 10, issue 4, june 2019

D. Bron MD, PhD, M. Maerevoet MD, E. Van den Neste MD, PhD, V. Delrieu MD, F. Offner MD, PhD, W. Schroyens MD, PhD, A. Van Hoof MD, PhD, G. Verhoef MD, PhD, J.B. Giot MD, J.P. Loly MD, A. Janssens MD, PhD, C. Bonnet MD, PhD

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

The 4th LYSA meeting

BJH - volume 9, issue 5, september 2018

C. Bonnet MD, PhD, M.C. Ngirabacu , M. Maerevoet MD, V. De Wilde MD, PhD, E. Van den Neste MD, PhD, M. André MD, PhD


The 4th edition of the LYSA meeting was organised by Professor Steven Legouill’s team and held in Nantes from the 8th to 10th February, 2018. It was a real opportunity for the 500 participants to learn novelties on lymphoma and to be updated on ongoing clinical trials conducted by this cooperative group. All the presentations were outstanding and gave us new indications on how to better treat our patients in the near future.
