Time to progression of disease and outcomes with second-line BTK inhibitors in relapsed/refractory mantle cell lymphoma

Management of relapsed/refractory mantle cell lymphoma

In this review we summarize the current evidence describing the management of patients with relapsed/refractory MCL and outline the various novel therapeutics that have been developed over the past two decades. We also describe how overall response rates, complete response rates, duration of responses, and life expectancy have dramatically increased with the introduction of novel therapies, particularly covalent Bruton Tyrosine Kinase inhibitors (BTKi) and chimeric antigen receptor T-cell (CAR-T) therapy. The most recent emerging options for patients with progressive disease following BTKi or CAR-T, including non-covalent BTKi, antibody-drug conjugates, Bcl-2 inhibitors, and bispecific antibodies, may further improve response rates and outcomes. Future directions should focus on identifying the best sequencing and/or combinations of the increasingly available treatment options while prioritizing strategies with curative potential.

Letting the mantle out of the bag

Mantle cell lymphoma is a rare disease that attracts the curiosity of clinicians and scientists due to its heterogeneous clinical behaviour, that can vary from indolent forms to the most aggressive presentations among non-Hodgkin lymphomas. The report by Eyre and colleagues describes the current treatment strategies available in most countries, and offers insights to clinicians for several intriguing difficult-to-treat scenarios.
