BJH - volume 13, issue 5, september 2022

D. Bron MD, PhD

SUMMARY

Chronic lymphocytic leukaemia (CLL) is a rapidly progressing field in haemato-oncology. The EHA 2022 meeting again provided an update on major clinical trials, the prognostic impact of TP53 mutation in the era of BCL2inh, new insights into the role of marrow microenvironment in the course of the disease, new approaches to Richter’ syndrome and many new promising drugs. The oral presentations about this topic, with practical importance for the clinicians, are covered in this article.

Primary gastric plasmacytoma: Case report of a rare plasma cell neoplasm

BJH - volume 12, issue 8, december 2021

O. Rizzo MD, D. Bron MD, PhD, M. Vercuyssen MD, A. De Wind MD, PhD, M. Roelandt MD, P. Eisendrath MD, PhD, A. Lemmers MD, PhD, N. Meuleman MD, PhD

SUMMARY

A 46-year-old woman presented with epigastric pain and weight loss for over a year. An upper endoscopy was performed and showed a polypoid lesion in the antropyloric region. Immuno-pathological report revealed a proliferation of plasma cell nature. The whole work-up including complete blood test, bone marrow biopsy and 18FDG-PET-CT did not detect extra gastric lesion of multiple myeloma. The diagnosis of extramedullary plasmacytoma of the stomach was established. Radiotherapy (44 Gy) with a curative intent was administered but the control biopsy showed residual disease. Endoscopic submucosal dissection was then performed with R0 resection (negative margins) leading to complete remission.

Rational approach of older patients with chronic lymphocytic leukaemia

SUMMARY

The majority of CLL patients are elderly, with a median age of those requiring a first line treatment, close to 76 years old. Nowadays, multiple treatment options are available for this disease, ranging from chemo immunotherapy regimens to biological therapies. The treatment decision in an older CLL patient is a four-step procedure, starting firstly with the assessment of treatment criteria. The second step is to evaluate the life-expectancy of the patient, its autonomy, vulnerabilities and the socio-economic status. The subsequent step is to define treatment options according to prognostic factors. Last, but not least, the patient should be involved in the final decision to know to what extend he is willing to receive a treatment with a potential curative or palliative intent. The assessment of an elderly CLL patient is a complex procedure, not only comprehending the evaluation of biological and hematological parameters but also clinical, social and psychological features, which equally contribute to the selection of the most valuable strategy.

Long-term treatment-free molecular remission in a FIP1L1-PDGFRA positive myeloid/lymphoid neoplasm with eosinophilia after Imatinib discontinuation

BJH - volume 11, issue 7, november 2020

SUMMARY

A 47-year-old patient was diagnosed with FIP1L1-PDGFRA-positive myeloid/lymphoid neoplasm with eosinophilia (F/P+ MLN-eo) and was successfully treated with Imatinib, achieving a sustained molecular treatment free remission (TFR) persisting three years after discontinuation.

Ibrutinib and bleeding management: a Belgian expert consensus

BJH - volume 11, issue 4, june 2020

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.

Chimeric antigen receptor T-cells: a new therapeutic option for relapsed/refractory B-cell malignancies and beyond

BJH - volume 10, issue 8, december 2019

T. Feys MBA, MSc, G. Roex , Y. Beguin MD, PhD, T. Kerre MD, PhD, X. Poiré MD, PhD, P. Lewalle MD, PhD, P. Vandenberghe MD, PhD, D. Bron MD, PhD, S. Anguille MD, PhD

Chimeric antigen receptor (CAR) T-cell therapy is a new cancer immunotherapy targeting specific cell surface antigens. This type of adoptive cell immunotherapy has been a breakthrough in the treatment of aggressive B-cell lymphoma and B-cell precursor acute lymphoblastic leukaemia (ALL) and is currently also being studied in other cancer types, including multiple myeloma and chronic lymphocytic leukaemia. This review will discuss the recent clinical developments and future perspectives of CAR T-cell therapy, with a focus on the clinical trials that led to the FDA and EMA approval of tisagenlecleucel (Kymriah®, Novartis) and axicabtagene ciloleucel (Yescarta®, Gilead) for the treatment of childhood/adult relapsed/refractory (r/r) B-cell precursor ALL and aggressive B-cell non-Hodgkin lymphoma.
