Tumor burden quantified by Soluble B-Cell Maturation Antigen and Metabolic Tumor Volume determine myeloma CAR-T outcomes.

Chimeric antigen receptor T-cell (CAR-T) therapy has emerged as a breakthrough treatment for relapsed and refractory multiple myeloma (RRMM). However, these products are complex to deliver and alternative options are now available. Identifying biomarkers that can predict therapeutic outcomes is crucial for optimizing patient selection.

Mutagenic impact and evolutionary influence of radiotherapy in hematologic malignancies.

Ionizing radiotherapy (RT) is a widely used palliative and curative treatment strategy for malignancies. In solid tumors, RT-induced double strand breaks lead to the accumulation of indels, and their repair by non-homologous end-joining has been linked to the ID8 mutational signature in resistant cells. However, the extent of RT-induced DNA damage in hematologic malignancies and its impact on their evolution and interplay with commonly used chemotherapies has not yet been explored.

Impact of Myc-Altered Pathology on Radiation Therapy Efficacy Among Patients With Relapsed/Refractory Large-B Cell Lymphoma: A Collaborative Study by ILROG.

Purpose: The presence of MYC and BCL2 translocations (ie, double-hit lymphoma, DHL) in large B-cell lymphoma (LBCL) is associated with reduced chemosensitivity, but less is known on its impact on radiotherapy (RT) efficacy.

Methods And Materials: Patients with LBCL who received their first course of RT for relapsed/refractory disease between 2008 and 2020 were eligible if there was adequate pathologic evaluation to be categorized as DHL versus non-DHL as per the World Health Organization (fifth edition). Separate analyses were conducted by treatment intent.

Radiation target nomenclature for lymphoma trials: consensus recommendations from the National Clinical Trials Network groups.

Contemporary lymphoma radiation target volumes that rely on post-systemic therapy imaging do not have standardised nomenclature. A forum of radiation oncology lymphoma leaders from the National Clinical Trials Network groups (NRG Oncology, Children's Oncology Group, SWOG Cancer Research Network, Alliance for Clinical Trials in Oncology, Eastern Cooperative Oncology Group-American College of Radiology Imaging Network Cancer Research Group, and the Canadian Cancer Trials Group) was convened and established standardised nomenclature for these volumes in the autumn of 2024. Involved-site radiotherapy includes the full cranial-caudal extent of prechemotherapy disease and takes into account axial anatomical changes only.

Management of bone disease with concurrent chimeric antigen receptor T-cell therapy for multiple myeloma.

In the intricate landscape of multiple myeloma, a hematologic malignancy of plasma cells, bone disease presents a pivotal and often debilitating complication. The emergence of Chimeric Antigen Receptor T-cell (CAR-T) therapy has marked a pivotal shift in the therapeutic landscape, offering novel avenues for the management of MM, particularly for those with relapsed or refractory disease. This innovative treatment modality not only targets malignant cells with precision but also influences the bone microenvironment, presenting both challenges and opportunities in patient care.
