The Belgian Haematological Society (BHS) Lymphoproliferative disease (LPD) committee updated the existing recommendations on diagnosis, prognostic scores, best strategies for front-line and subsequent-line treatment of small lymphocytic lymphoma (SLL)/chronic lymphocytic leukaemia (CLL), according to robust new data.

The oncological treatment landscape is evolving at a very rapid pace with a continuous stream of novel treatment options. To fully leverage these therapeutic advances in clinical practice it is important to facilitate a rapid access to innovative anticancer drugs for patients. Specifically for Belgium, the delay from EMA approval to reimbursement for anticancer drugs is very long, with an average of almost 600 days, and a substantial proportion of innovative drugs never make it to the patient. The stringent focus of the Belgian Commission for Reimbursement of Medicines (CRM) on overall survival (OS) data in reimbursement decisions is believed to be an important contributor to this situation. However, the ever-increasing pace at which new anticancer therapies are being developed in combination with an earlier detection of cancer will make it increasingly difficult to present mature OS data at the time of regulatory approval in the years to come. As such, there is an urgent need for a debate with the regulators to consider more readily available endpoints in their reimbursement assessments. In fact, when a strong treatment effect is seen on an intermediate endpoint such as disease-free or progression-free survival, a benefit in OS is quite likely. As such, our reimbursement system needs to be adapted to better align with the scientific progress in oncology. In this, a temporary reimbursement decision based on intermediate endpoints could give Belgian patients earlier access to promising lifesaving medicines. In this, we as oncologists, including specialists in haematology, respiratory oncology, and gastrointestinal cancer, strongly encourage the CRM to use the grading provided by the ESMO magnitude of clinical benefit scale to evaluate the clinical added value of future cancer treatments. This will not only facilitate a faster patient access to innovative therapies, but will also help policy-makers in advancing ‘accountability for reasonableness’ in their resource allocation deliberations.

Most of the selected abstracts deal with longer-term results of clinical trials already presented previously and urgent medical needs still existing in chronic lymphocytic leukaemia (CLL).

Approximately 30–40% of patients with diffuse large B-cell lymphoma (DLBCL), not otherwise specified (NOS), will relapse or are unable to obtain a complete remission (CR) after frontline treatment. These patients have a poor prognosis and represent a therapeutic challenge. In this article, we reviewed the recent literature to update the practice guidelines of the Belgian Hematology Society (BHS) Lymphoproliferative Disease Committee for the treatment of relapsed or refractory (R/R) DLBCL. In the first part, we will focus on first relapse and the role of CAR T-cell therapy in first and second relapse. In the second part, we will focus on novel treatment options for patients with a second or higher relapse, secondary central nervous system (CNS) relapse and high-grade lymphoma.

Waldenström Macroglobulinaemia is a rare indolent B-cell lymphoproliferative disorder, which is characterised by infiltration of the bone marrow by lymphoplasmacytic cells in combination with a monoclonal IgM gammopathy. In 2015, the first Belgian guidelines on diagnosis, staging and treatment were published with a first update in 2018. Since then, however a lot has changed. The discovery of the molecular markers MYD88 affected the diagnostic work up. There have also been radical changes in treatment and prognosis due to the use of Bruton tyrosine kinase inhibitors. In this second update, we revise both diagnosis and treatment and we have a look at the future.

Lymphomas are the most common haematological malignancy and represent a heterogenous group of lymphoproliferative diseases with a variable prognosis. Chemotherapy and radiotherapy, and anti-CD20 immunotherapy for B-cell lymphomas, currently form the basis of lymphoma treatment. New agents, especially new forms of cancer immunotherapy, such as bispecific antibodies (bsAbs), have expanded therapeutic approaches in the last years. bsAbs have two different antigen binding sites, which enables them to simultaneously target tumour cells and immune effector cells (T-cells). By binding and activating T-cells in the proximity of tumour cells, an effective T-cell mediated anti-tumour response can be achieved. Target antigens in lymphomas are mostly CD19 or CD20 on the malignant B-cell and CD3 on the T-cell. This article will briefly review the basic principles and mechanisms of action of bsAbs, discuss the molecules approved or in advanced clinical development for lymphomas with their most relevant (dose-escalation/dose-expansion) trials, and pay attention to possible adverse events and future perspectives of bsAbs.
