Article Synopsis
  • Innovative therapeutic strategies have emerged to improve outcomes for lymphoma patients, but high-risk mantle cell lymphoma (MCL) remains a significant challenge due to its aggressive nature.
  • STP-B, a small molecule inhibitor targeting CTP synthase 1 (CTPS1), has shown effectiveness against MCL cells by exploiting their need for nucleotide synthesis, leading to cell cycle arrest and enhanced cell death, particularly when combined with the BCL2 inhibitor venetoclax.
  • The study positions CTPS1 as a promising therapeutic target for MCL, paving the way for innovative, chemotherapy-free treatment options that could enhance patient outcomes.

Article Synopsis
  • The presence of donor Vγ9Vδ2 T-cells after haploidentical hematopoietic stem cell transplant (h-HSCT) is linked to better disease-free survival, as these cells can target tumor cells without triggering severe side effects.
  • A clinical study assessed the safety of generating these T-cells by combining zoledronic acid (ZA) with interleukin-2 (IL-2), showing that the procedure is safe and successfully increases T-cell numbers in patients.
  • The study's outcomes suggest potential for further research into using this immunotherapy to reduce relapse rates after h-HSCT, indicating that more extensive trials may come next.

Article Synopsis
  • Researchers used CRISPR/Cas9 to create TP53-/- clones from human myeloma cell lines to study p53-dependent gene expression, identifying a functional score based on 13 genes downregulated when p53 is silenced.
  • This score can differentiate myeloma cells based on TP53 status, predict patient survival, and identifies patients with complete TP53 inactivation.
  • The study found that the p53-regulated gene BAX impacts myeloma cell sensitivity to specific treatments, and combining MCL1 and BCL2 inhibitors may provide better treatment options for patients with TP53 inactivation.

Article Synopsis
  • * Researchers used genomic and RNA-sequencing analyses to find that subclones of resistant cancer cells develop mutations (like CARD11) that enable them to evade the therapies by enhancing specific survival genes, contributing to treatment resistance.
  • * They proposed a new approach that targets MALT1, a key partner in the resistance pathway, which shows potential for overcoming resistance and improving treatment outcomes in MCL, even in the presence of resistance mutations.

Molecular monitoring of tumor-derived alterations has an established role in the surveillance of leukemias, and emerging nucleic acid sequencing technologies are likely to similarly transform the clinical management of lymphomas. Lymphomas are well suited for molecular surveillance due to relatively high cell-free DNA and circulating tumor DNA concentrations, high somatic mutational burden, and the existence of stereotyped variants enabling focused interrogation of recurrently altered regions. Here, we review the clinical scenarios and key technologies applicable for the molecular monitoring of lymphomas, summarizing current evidence in the literature regarding molecular subtyping and classification, evaluation of treatment response, the surveillance of active cellular therapies, and emerging clinical trial strategies.

Article Synopsis
  • Aggressive B-cell malignancies like mantle cell lymphoma (MCL) depend on their microenvironment, and understanding these interactions can improve treatments.
  • A transcriptomic analysis compared circulating MCL cells to those in lymph nodes, revealing that interleukin-32 beta (IL32β) is secreted in a microenvironment-dependent manner and is linked to tumor survival.
  • The study found that IL32β influences monocyte polarization into MCL-associated macrophages, promoting tumor support, and showed that inhibiting the NIK/alternative-NFkB pathway can disrupt this survival mechanism.
