BHS guidelines on supportive care in lymphoma: Part 1

BJH - volume 13, issue 3, may 2022

M. Janssens MD, K. Saevels MD, V. Vergote MD, J. Lemmens MD, S. Bailly MD, A. Janssens MD, PhD, S. Snauwaert MD, PhD, M. André MD, PhD

SUMMARY

Besides disease-directed therapy, patients with lymphoma are in need of a wide range of supportive measures. In the first part of this guideline the use of anti-emetic therapy, the use of granulocyte colony stimulating factor (G-CSF) and antibiotic prophylaxis for pneumocystis jirovecii are discussed. In part 2 of this guideline we will discuss cardiac support, prevention and treatment of tumour lysis syndrome and the role of physiotherapy.

Diagnosis and treatment of peripheral T-cell lymphomas: Update recommendations of the Belgian Hematology Society (BHS)

BJH - volume 13, issue 2, march 2022

A. Wolfromm MD, S. Bailly MD, E. Van den Neste MD, PhD, M. André MD, PhD, K. Saevels MD, H. Antoine-Poirel MD, PhD, T. Tousseyn MD, PhD, V. Van Hende MD, S. Snauwaert MD, PhD, A. Janssens MD, PhD, C. Jacquy MD, C. Bonnet MD, PhD

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.

How to treat classical Hodgkin’s lymphoma in older patients: Belgian expert opinion

BJH - volume 12, issue 7, november 2021

S. Snauwaert MD, PhD, V. Van Hende MD, A. Janssens MD, PhD, M. André MD, PhD, S. van Hecke MD, E. Van den Neste MD, PhD, On behalf of the lymphoproliferative disease committee BHS

SUMMARY

Classical Hodgkin’s lymphoma (cHL) is a rather rare disease with an incidence of 2-3/100,000 per year and typically presents in patients at the age of 20–30. It is however well known that a second peak occurs at the age of 60–65 years.1 Nowadays Hodgkin is a curable disease for most of the younger patients but treatment is more difficult and less successful in the older patient population. In this review, we want to summarise the possibilities for the treatment of cHL patients above 60 years, with a focus on evidence from the rather rarely available clinical trials. We also look at future treatments. In this article we will use the term ‘older patients’ for patients of 60 years and older at diagnosis. We will make a distinction between fit patients older than 60 years and frail or vulnerable patients (so called elderly).

Ibrutinib and atrial fibrillation: A Belgian expert consensus paper

BJH - volume 12, issue 4, june 2021

SUMMARY

Over the last decade, the oral Bruton’s tyrosine kinase (BTK) inhibitor ibrutinib induced a paradigm shift in the treatment of patients with chronic lymphocytic leukaemia (CLL), mantle cell lymphoma (MCL), and Waldenströms macroglobulinemia (WM). In clinical trials and in real-world studies, ibrutinib proved to be an effective agent with an overall favourable safety and tolerability profile. However, compared with standard chemo-immunotherapy (CIT), ibrutinib was associated with a higher incidence of atrial fibrillation (AF). The patho-physiological mechanisms underlying this increased AF incidence are not completely understood, but it is thought to be related to off-target inhibitory effects of ibrutinib on the Tec protein tyrosine kinase (TEC) in cardiac cells. The prevalence of AF in patients treated with ibrutinib is highest during the first three months of therapy, which warrants an increased vigilance during this treatment phase. However, AF in patients treated with ibrutinib is generally well manageable without ibrutinib discontinuation. Prior to the start of ibrutinib treatment, identification and addressing modifiable risk factors for AF is a first important step. The threshold for haematologists to consult a cardiologist or a cardio-oncologist should be low and a close collaboration between both specialties is warranted. Unnecessary ibrutinib interruptions should be avoided, and uncomplicated AF is not a valid reason to discontinue or interrupt ibrutinib. If anticoagulation is required, direct oral anticoagulants are preferred. In this paper, a panel of haematology and cardiology specialists have provided practical guidance on how to evaluate patients prior to ibrutinib treatment and monitor during ibrutinib therapy. Furthermore, they have provided practical guidance on how to manage AF in ibrutinib-treated patients.

CAR-T cells: New developments and implications in lymphoma

BJH - 2021, issue 2, march 2021

G. Crochet MD, E. Collinge MD, H. Vellemans MD, A. Bosly MD, PhD, M. André MD, PhD

SUMMARY

Recently, the use of chimeric antigen receptor modified T cells or CAR-T cells has emerged in the therapeutic arsenal of several hematological pathologies, including lymphoma. These CAR-T cells are the product of extensive research on understanding the mechanisms of tumour immunity and are the product of cellular engineering. By combining the specific recognition of an antibody and the activation pathways of a cytotoxic cell, CAR-T cells allow promising clinical results, but they also see the occurrence of side effects that are more specific to these treatments, which it is essential to manage in a multidisciplinary team. Different CAR-T cells are currently available, particularly in diffuse large cell B lymphoma. The trials that have enabled their use differ on many points, including patient selection, the manufacture of the CAR or the pre-therapeutic conditioning. In the future, the use of this expensive therapy could be extended to other lymphomas and new generations of CAR-T cells could emerge.

Ibrutinib and bleeding management: a Belgian expert consensus

BJH - volume 11, issue 4, june 2020

A. Janssens MD, PhD, D. Bron MD, PhD, V. Van Hende MD, V. Galle MD, K. Jochmans MD, PhD, S. Meers MD, PhD, M. André MD, PhD, M-C. Ngirabacu MD, PhD, K.L. Wu MD, B. De Prijck MD, P. Verhamme MD, PhD, C. Hermans MD, PhD

SUMMARY

In recent years ibrutinib emerged as a paradigm shifting agent in the treatment of chronic lymphocytic leukaemia (CLL), mantle cell lymphoma (MCL) and Waldenström’s macroglobulinemia (WM). In clinical trials and in real-world studies ibrutinib proved to be an effective agent with an overall favourable tolerability profile. However, compared with standard chemo-immunotherapy (CIT), ibrutinib was associated with a higher incidence of clinically significant bleeding. This has been hypothesized to be linked to the platelet-specific effects of inhibiting Bruton’s tyrosine kinase (BTK). Most bleeding events under ibrutinib are low-grade with a decreasing incidence over time. However, bleeding can have a significant impact on patients and interfere with persistence and compliance of ibrutinib treatment. Currently, no clear consensus exists on the use of ibrutinib in patients with an increased bleeding risk, on the management of ibrutinib-induced bleeding and on the use of ibrutinib around surgery or invasive procedures. In this paper, a panel of Belgian haematology and haemostasis specialists formulated practical advice on bleeding prevention and management in ibrutinib-treated patients.
