This risk-adapted approach reflects a paradigm shift in MCL management, emphasizing the need for early molecular risk assessment to guide treatment decisions. In this scenario, TP53 mutations are no longer supporting actors, but a game-changer for the prognosis and treatment of patients with MCL.
A notable feature of the HRS-like cells in this case is the gain of markers associated with CHL, such as CD30 and CD15. This immunophenotypic shift highlights the concept of lymphoma plasticity, where the tumor cells evolve in response to selective pressures, such as CAR T cell therapy.

In addition, changes in cell buoyant mass within primary patient specimens ex vivo correlate with sensitivity to Bruton's tyrosine kinase inhibitors in vivo in MCL and chronic lymphocytic leukemia, another B cell malignancy. These findings highlight the value of biophysical properties as biomarkers of response in pursuit of future precision therapeutic strategies.
From a safety perspective, much progress has been made in reducing the burden of side effects and broadening access; however, barriers remain before TCE therapies can be widely available to all patients. This brief review addresses some of the latest strategies being tested to elevate TCE therapies as pillars of immunotherapy for B-NHL.
In conclusion, our findings suggest that c-Myc overexpression and MYC rearrangement are associated with ibrutinib resistance in MCL. Detecting MYC rearrangement in selected MCL cases could be critical for optimizing treatment strategies and improving patient outcomes.
Mechanistically, we discovered that enhancer positioning at local topological centres is required for promoter engagement, with EBF1 acting as a permeable barrier to loop-extruding cohesin at enhancers. Extending these findings to T cell leukaemia, we show that lineage-determining transcription factors such as EBF1 and TCF1 radially position enhancers within gene loci to enable multi-enhancer regulation of key oncogenes at the single-allele level.
