Background: Treatment of refractory/relapsing diffuse large B cell (R/R DLBCL) lymphoma remains a challenge. Radiation therapy (RT) has versatile roles in R/R DLBCL treatment: it can be used in the peri-transplant setting for transplant-eligible candidates, or as a salvage or palliation therapy depending on the extent of the disease in transplant-ineligible patients. The introduction of chimeric antigen receptor (CAR) T-cell therapy has changed the landscape of R/R DLBCL. RT has been used as a bridging therapy to CAR T-cell therapy in order to control disease progression during its manufacturing period. However, optimal RT and CAR T-cell therapy integration is still unknown. Salvage strategies for R/R DLBCL post-CAR T-cell therapy have been little studied.
Case Report: Here, we present a case of primary refractory DLBCL with residual disease post-CAR T-cell therapy successfully treated with salvage RT.
Conclusion: Radiotherapy could be an effective salvage strategy for R/R DLBCL post-CAR T-cell therapy. Exact mechanisms await exploring.

Purpose Of Review: Cutaneous T cell lymphomas (CTCLs) are comprised of a heterogenous group of non-Hodgkin lymphomas that can be difficult to treat and are often refractory to standard therapies. Mycosis fungoides (MF) and Sezary syndrome (SS) are the most common subtypes, accounting for the majority of CTCLs. There is no standard of care, and no treatments are curative.

Background: Ewing's sarcoma (EwS), a common pediatric bone cancer, is associated with poor survival due to a lack of therapeutic targets for immunotherapy or targeted therapy. Therefore, more effective treatment options are urgently needed.
Methods: Since novel immunotherapies may address this need, we performed an integrative analysis involving single-cell RNA sequencing, cell function experiments, and humanized models to dissect the immunoregulatory interactions in EwS and identify strategies for optimizing immunotherapeutic efficacy.

Background: B-Raf proto-oncogene, serine/threonine kinase (BRAF)-mutant microsatellite stable (MSS) colorectal cancer (CRC) constitutes a distinct CRC subgroup, traditionally perceived as minimally responsive to standard therapies. Recent clinical attempts, such as BRAF inhibitors (BRAFi) monotherapy and combining BRAFi with other inhibitors, have yielded unsatisfactory efficacy. This study aims to identify a novel therapeutic strategy for this challenging subgroup.

Background: The efficacy of immune checkpoint inhibitors (ICIs) depends on the tumor immune microenvironment (TIME), with a preference for a T cell-inflamed TIME. However, challenges in tissue-based assessments via biopsies have triggered the exploration of non-invasive alternatives, such as radiomics, to comprehensively evaluate TIME across diverse cancers. To address these challenges, we develop an ICI response signature by integrating radiomics with T cell-inflamed gene-expression profiles.

Background: The use of tumor-infiltrating T lymphocytes (TIL) that recognize cancer neoantigens has led to lasting remissions in metastatic melanoma and certain cases of metastatic epithelial cancer. For the treatment of the latter, selecting cells for therapy typically involves laborious screening of TIL for recognition of autologous tumor-specific mutations, detected through next-generation sequencing of freshly resected metastatic tumors. Our study explored the feasibility of using archived formalin-fixed, paraffin-embedded (FFPE) primary tumor samples for cancer neoantigen discovery, to potentially expedite this process and reduce the need for resections normally required for tumor sequencing.
