SUMMARY

Peripheral T-cell lymphoma (PTCL) is a heterogeneous group of aggressive diseases associated with poor outcomes. Recent progress in understanding of the biology and pathogenesis based on molecular profiling and next-generation sequencing has led to the introduction of new provisional entities in the World Health Organization (WHO) classification system of 2017 and to the emergence of new drugs.1 Previous Belgian guidelines were published in 2013.2 This review will discuss the diagnosis, work-up and treatment of PTCL including these advances as well as the limitation of the availability of drugs according to the Belgian reimbursement rules.

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

SUMMARY

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.

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

SUMMARY

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.

Management of cutaneous T & B cell lymphomas: a comprehensive review

BJH - volume 9, issue 3, june 2018

M. de Vicq de Cumptich MD, C. Springael MD, PhD, J. Somja MD, C. Bonnet MD, PhD, P. Heimann MD, PhD, U. Sass MD, A. Janssens MD, PhD, D. Bron MD, PhD

SUMMARY

Primary cutaneous lymphomas are a heterogeneous group of diseases with indolent or aggressive behaviour, skin-limited or systemic extension, from T or B cell origin. The optimal management requires the multi-disciplinary approach with dermatologists, hemato-oncologists, pathologists and molecular biologists. The objective of this review is to harmonise the work-up and the treatment of these different entities of cutaneous T or B cell lymphoma in Belgium, according to the availability of the drugs and specialised treatment such as extracorporeal photopherisis or total skin electron beam therapy.
