Post-BTK inhibitor mantle cell lymphoma: When is CAR-T not the answer?

In a large multicentre retrospective real-world analysis, Hess and colleagues describe outcomes in post-Bruton tyrosine kinase inhibitor (BTKi) mantle cell lymphoma patients managed in clinical practice prior to availability of brexucabtagene autoleucel (Tecartus). Outcome data not only provide a useful benchmark for future studies but also highlight the great challenges that still lie ahead in managing this challenging patient cohort.
