A Patient-Derived Xenograft Repository Capturing Clinical and Molecular Heterogeneity of Large B-cell Lymphoma.

UNLABELLED: Large B-cell lymphomas (LBCL) are a clinically and molecularly diverse group of malignancies with a rapidly evolving therapeutic landscape that has introduced new areas of clinical need, such as post-CD19 chimeric antigen receptor T (CART19) progression. Patient-derived xenograft (PDX) models are an important tool for mechanistic studies and preclinical evaluation of new therapies and can be generated from a variety of clinical contexts that capture tumor-intrinsic resistance mechanisms. We therefore undertook a comprehensive effort to generate PDX models that encompass the molecular landscape of LBCLs and include important clinical scenarios for new drug development. Here, we describe the first 48 models within this publicly available repository, capturing the transcriptional and genetic subsets of LBCL. These models also include 23 generated from post-CART19 progression patient biopsies, which reproduce patterns of progression driven by CD19 mutation or expression loss, as well as tumor cell-intrinsic CART19 resistance that we validated in vivo. SIGNIFICANCE: Here, we describe X-LYMPH (Xenografts of Lymphoma), a publicly available and molecularly annotated PDX repository that captures the heterogeneity of LBCL. X-LYMPH includes models of CAR T-cell resistance, providing a shared foundation for mechanistic research and therapeutic development for lymphomas.

Testicular aggressive B-cell lymphoma with plasmablastic morphology harboring concurrent IGH::MYC and IGH::BCL2 rearrangements.

BACKGROUND: Aggressive B-cell lymphomas with plasmablastic morphology are uncommon neoplasms that may exhibit overlapping morphologic, immunophenotypic, and genetic features of plasmablastic lymphoma (PBL) and double-hit lymphoma (DHL). Concurrent IGH::MYC and IGH::BCL2 rearrangements are rarely encountered in this setting, particularly in the testis. Here, we describe an unusual case presenting significant diagnostic challenges at the interface between PBL and DHL. CASE PRESENTATION: We report a 66-year-old, immunocompetent man presenting with a 5 cm left testicular mass. Histologic examination revealed diffuse proliferation of large atypical lymphoid cells with plasmablastic morphology. Immunohistochemically, the tumor expressed CD138, CD38, and MUM1, with focal BCL2, c-MYC protein, and CD79a positivity, while CD20, CD19, PAX5, CD10, BCL6, and ALK were negative. EBV-encoded RNA in situ hybridization was negative. Fluorescence in situ hybridization identified IGH::MYC [t(8;14)] rearrangement in 45% and IGH::BCL2 [t(14;18)] rearrangement in 21% of analyzed nuclei. Next-generation sequencing additionally revealed BRAF V600E mutation, CDKN2A deletion, and human leukocyte antigen class I genomic alterations. CONCLUSION: This case highlights a rare testicular aggressive B-cell lymphoma with plasmablastic morphology and concurrent IGH::MYC and IGH::BCL2 rearrangements, representing a diagnostically challenging neoplasm at the interface between PBL and DHL. Our findings underscore the value of integrated morphologic, immunophenotypic, cytogenetic, and molecular analyses in evaluating aggressive B-cell lymphomas with plasmablastic features arising in immune-privileged sites.

SLC1A5 and NUMA1 are potential regulators and therapeutic targets of ferroptosis in diffuse large B-cell lymphoma.

BACKGROUND: Ferroptosis, a form of regulated cell death driven by iron-dependent lipid peroxidation, has emerged as a potential therapeutic target in various cancers, including diffuse large B-cell lymphoma (DLBCL). This study aimed to identify and characterize ferroptosis-related panel genes with prognostic value in DLBCL. METHODS: Transcriptomic data from Gene Expression Omnibus (GEO) and The Cancer Genome Atlas (TCGA) were analyzed to identify differentially expressed genes (DEGs) in DLBCL samples. Gene set variation analysis (GSVA) and network topology analysis were performed to identify key ferroptosis-related genes. Lasso regression was utilized to construct a prognostic model based on the identified panel genes. In vitro experiments, including gene silencing, overexpression, and ferroptosis induction, were conducted to evaluate the functional roles of the identified genes, NUMA1 and SLC1A5, in DLBCL cells. RESULTS: A panel of ferroptosis-related genes with prognostic value, including NUMA1 and SLC1A5, was identified in DLBCL samples. Silencing SLC1A5 or overexpressing NUMA1 in DLBCL cells enhanced sensitivity to ferroptosis inducers, increased intracellular labile iron and lipid peroxidation levels, promoted mitochondrial damage, and modulated the expression of key ferroptosis markers. Furthermore, SLC1A5 silencing or NUMA1 overexpression augmented radiation-induced ferroptosis in DLBCL cells. CONCLUSION: NUMA1 and SLC1A5 are potential ferroptosis regulators and therapeutic targets in DLBCL. Silencing the ferroptosis-suppressive transporter SLC1A5 or restoring NUMA1 expression promotes lipid peroxidation and ferroptotic cell death, thereby sensitizing DLBCL cells to ferroptosis and enhancing radiosensitivity-providing a rationale for novel ferroptosis-based therapeutic strategies.

[Aggressive B-cell lymphomas with MYC gene cluster amplification: a clinicopathological analysis of eight cases].

Objective: To investigate the clinicopathological characteristics, molecular genetics, treatments and prognosis of aggressive B-cell lymphomas (ABCL) with MYC gene cluster amplification. Methods: Eight cases of ABCL with MYC gene cluster amplification were collected, including 6 cases from the First Affiliated Hospital, Zhejiang University School of Medicine, Hangzhou, China and 2 consultation cases from outside hospitals. The histomorphology, immunohistochemical profiles, and molecular genetic characteristics were analyzed. Clinical follow-up and literature review were also conducted. Results: Among the eight patients, six were male and two were female, with an age 71.5 (61.7, 74.2) years. All six in-house patients presented with abdominal pain at onset, without B symptoms. Most cases were classified as Ann Arbor stage Ⅲ-Ⅳ. Extranodal involvement occurred in 5 of the 6 in-house cases, primarily affecting the gastrointestinal tract (4/5). All initial bone marrow biopsies showed no evidence of lymphoma. One patient had a history of immunosuppression following renal transplantation. Two cases exhibited diffuse large B-cell lymphoma (DLBCL) morphology. The other six showed high-grade features, while three of them showed Burkitt lymphoma-like morphology. Except for one case of blastoid variant mantle cell lymphoma, the remaining six cases (6/7) displayed a germinal center B-cell phenotype. None of the in-house cases harbored bcl-2 or bcl-6 rearrangements as shown by fluorescence in situ hybridization. 11q alterations were identified in all but one consultation case, including gain/loss type in five cases and 11q gain in two. 11q telomere loss of heterozygosity by chromosomal microarray analysis was not detected in one of the two cases with 11q gain that was subject to the test. The duration of follow-up ranged from 5.9 to 55.5 months, with 5 patients alive at the end of the study. Conclusions: ABCL with MYC gene cluster amplification often presents high-grade morphology and gastrointestinal involvement, which strongly suggests the alteration of 11q. It seems to have a favorable prognosis.

Second Primary Malignancies in Patients With B-Cell Lymphomas Treated With Bruton's Tyrosine Kinase Inhibitors: A Systematic Review and Meta-Analysis.

OBJECTIVE: To evaluate the overall second primary malignancy (SPM) burden in patients with B-cell lymphomas treated with Bruton's tyrosine kinase (BTK) inhibitors and compare SPM risk versus non-BTK inhibitor or placebo controls. METHODS: We searched major databases from inception to September 30, 2025. The primary outcome was SPM incidence. Consistent treatment backgrounds were defined as comparable baseline clinical and treatment characteristics, with BTK inhibitor exposure as the main between-arm difference. RESULTS: Fifty-two studies involving 9337 patients were included, mainly CLL/SLL; MCL was the largest non-CLL/SLL subtype. Pooled SPM incidence was 8% (95% CI: 6%-11%) with a median follow-up of 31.5 months. Multivariable meta-regression identified follow-up duration as the only independent predictor, whereas disease subtype, inhibitor generation, prior therapy lines, study design, and age were not significant. Furthermore, SPM patterns were comparable between CLL/SLL and non-CLL/SLL cohorts. Compared with controls, BTK inhibitors did not significantly increase SPM risk (RR = 1.30, 95% CI: 0.95-1.78), a finding confirmed in analyses with consistent treatment backgrounds (RR = 1.03, 95% CI: 0.85-1.25). CONCLUSIONS: SPMs occur across disease backgrounds and are mainly influenced by follow-up duration. Current evidence does not establish a direct carcinogenic effect of BTK inhibitors.

Oncogenic Mutations and Tumor Microenvironment Alterations in Diffuse Large B-Cell Lymphoma With Bulky Disease.

BACKGROUND: Bulky disease represents a clinically aggressive subset of diffuse large B-cell lymphoma (DLBCL) associated with adverse clinical outcomes. The aim of this study was to investigate the influence of oncogenic mutations and tumor microenvironment alterations on bulky disease in DLBCL. METHODS: We analyzed a cohort of 939 patients with newly diagnosed DLBCL. Using DNA (n = 934) and RNA (n = 524) sequencing, we compared oncogenic mutations and tumor microenvironment (TME) alterations based on tumor diameter, with cutoff values at 5.0 cm and 10.0 cm. Further stratification by mutations in key genes (CD58, STAT6, EBF1) correlated with tumor diameter revealed distinct transcriptomic and immunologic profiles. Subsequent single-cell RNA sequencing, guided by these mutational signatures, resolved the cellular heterogeneity within the TME. RESULTS: Integrative analysis revealed that tumor diameter correlated with increased incidence of mutations in CD58, STAT6, and EBF1; adverse genetic subtypes such as EZB-like MYC+ and TP53Mut; activation of oncogenic pathways (JAK/STAT, BCR, PI3K, and MYC); and an immunosuppressive tumor microenvironment. Notably, immune checkpoint molecules varied across the bulky stages, with CTLA-4, TIGIT, ICOS, and CD28 expression inversely correlated with tumor diameter, while CD70 and 4-1BBL expression positively correlated. Single-cell RNA sequencing further revealed mutation-specific tumor microenvironment insights. CD58-mutated tumor exhibited a profoundly immune-deserted microenvironment dominated by malignant B cells with minimal immune infiltration, whereas STAT6-mutated tumor was associated with increased fibroblasts and CD4 + T cells, particularly regulatory T cells (Treg) and Th1-like cells; EBF1-mutated tumor was characterized by increased proportions of malignant B cells. CONCLUSIONS: Collectively, our findings highlight the biological complexity of bulky disease, identifying candidate molecular targets and providing a biological framework for future therapeutic hypothesis generation in this clinically aggressive subset of DLBCL.

LymphGen-Sig: Integrating Genetic and Transcriptional States to Predict Therapeutic Response in Diffuse Large B-Cell Lymphoma.

PURPOSE: Genetic classification may advance precision medicine in diffuse large B-cell lymphoma (DLBCL), but existing tools like LymphGen (LG) are limited by complexity and incomplete classification and do not incorporate nongenetic features that affect disease biology and therapeutic outcomes. To address these limitations, we developed LG-sig (LGsig), a gene expression-based platform that classifies all DLBCLs and harmonizes both genetic and nongenetic dimensions of the disease. METHODS: LGsig was built on the distinct subtype-specific gene expression signature of each LG class using paired genomic and transcriptomic data (National Cancer Institute/British Columbia Cancer Agency; N = 764). Model development was restricted to DLBCLs classified into MYD88L265P and CD79B mutations (MCD), BCL6 translocation and NOTCH2 mutations (BN2), EZH2 mutations and BCL2 translocation (EZB), or SGK1 and TET2 mutations (ST2). Gene features were selected by differential gene expression, with 294 genes being optimal for classification using a nearest shrunken centroid classifier. LGsig classifications were designated as MCDsig, BN2sig, ST2sig, and EZBsig. The final model was applied to RNAseq from archival samples from the POLARIX trial (N = 678) to assess outcomes after polatuzumab vedotin-R-CHP (pola-R-CHP) or rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP) for each LGsig subtype. RESULTS: LGsig accurately identified LG subtypes using transcriptional data alone and extended assignments to all previously LG-unclassified cases. Importantly, LG-unclassified DLBCLs reassigned by LGsig mirrored the transcriptional and clinical features of their corresponding LG counterparts, supporting their reclassification. In addition, LGsig reassigned LG A53 DLBCLs, characterized by aneuploidy and TP53 alterations, into more biologically and therapeutically relevant LGsig clusters. Finally, LGsig improved the performance of LG as a biomarker in the POLARIX study, by identifying distinct DLBCL subtypes exhibiting a survival benefit with pola-R-CHP over R-CHOP in both LG-classified and LG-unclassified cases. CONCLUSION: LGsig expands molecular classification beyond current genetic classifiers in DLBCL by integrating both genetic and transcriptional dimensions of the disease to better inform subtype-specific therapeutic strategies.

Tumor-Infiltrating Clonal Hematopoiesis Is Associated with Adverse Clinical Outcomes in Diffuse Large B-cell Lymphoma.

UNLABELLED: Tumor-infiltrating clonal hematopoiesis (TI-CH) contributes to the progression of nonhematologic cancers. CH is prevalent in the peripheral blood of patients with diffuse large B-cell lymphoma (DLBCL), but TI-CH prevalence and clinical relevance remain largely unexplored. In this study, through genome- and exome-wide sequencing of DLBCL biopsies and blood samples from 304 treatment-naïve patients, we identified TI-CH in 13.5% of cases, which emerged as an independent risk indicator for disease progression and death. TI-CH cases had an enrichment of inflammatory myeloid signatures revealed by gene expression profiling of tumor biopsies. In addition, we developed a TI-CH-associated prognostic signature (CAPS) based on 24 differentially expressed genes. A high CAPS score correlated with poor survival across four patient cohorts and remained significant in three cohorts after adjustment for patient age, sex, International Prognostic Index score, and cell-of-origin classification. Collectively, these findings establish a link between TI-CH and clinical outcomes and implicate the inflammatory signature as the potential underlying basis. SIGNIFICANCE: TI-CH correlates with disease progression and death in patients and with the inflammatory modeling of the DLBCL tumor microenvironment. Our results underscore the clinical and biological relevance of TI-CH and suggest its potential as a biomarker for risk stratification and as a target for therapeutic intervention in DLBCL.

RPLP0 drives diffuse large B-cell lymphoma cell proliferation through reactive oxygen species-dependent AKT/mTOR activation and inhibition of stress-induced autophagy.

Diffuse large B-cell lymphoma (DLBCL) is a common, aggressive subtype of non-Hodgkin lymphoma with poor outcomes. Identifying the primary molecular causes of DLBCL remains key. The present study examined the function of ribosomal protein lateral stalk subunit P0 (RPLP0) in DLBCL pathogenesis. The Cancer Genome Atlas-DLBCL and GSE12453 datasets overlapping differentially expressed genes were identified. Hub genes were identified via protein-protein interaction network analysis. DLBCL cells were subjected to functional tests following RPLP0 overexpression or knockdown. Reverse transcription-quantitative PCR, western blotting, flow cytometry, transmission electron microscopy, colony formation assay and biochemical analysis were among the tests performed. N-acetylcysteine (NAC), rapamycin (RAPA) and 3-MA were among the medication therapies. In the DLBCL datasets, six ribosome-associated genes were differentially expressed. RPLP0 knockdown inhibited the proliferation of DLBCL cells and caused G2-phase arrest, without impacting apoptosis. Thioredoxin, heat shock protein family A member 1A and heat shock protein family B member 1 expression was downregulated by RPLP0 knockdown, which also increased the NAD+/NADH ratio, promoted reactive oxygen species (ROS) accumulation and caused mitochondrial membrane potential depolarization. Meanwhile, 3-MA reversed the effects of RPLP0 knockdown, which encouraged LC3-II accumulation, autophagy-related gene 5 (ATG5) overexpression and an increase in autophagic vesicles. Autophagy-related indicators were decreased, and AKT/mTOR phosphorylation was increased by RPLP0 overexpression, which RAPA inhibited. NAC therapy preserved the viability of RPLP0-silenced cells, restored p-AKT/p-mTOR levels and restored normal LC3 and ATG5 expression. These findings suggest that RPLP0 regulates stress-induced autophagy through ROS-dependent AKT/mTOR signaling and may represent a potential therapeutic target for DLBCL.

Efficacy of R-GDP therapy as salvage chemotherapy for relapsed or refractory diffuse large B-cell lymphoma.

R-GDP has been established as an effective salvage treatment for Rel/Ref DLBCL. We aimed to clarify the efficacy of R-GDP therapy. We included 41 consecutive patients with Rel/Ref DLBCL, who received R-GDP therapy as salvage chemotherapy at our hospital between January 2014 and August 2024. Thirty-three patients received R-GDP therapy as a 2nd-line regimen, whereas 8 received R-GDP as a 3rd or later-line regimen. The ORR was 70.7%. 23 out of 25 relapsed patients (92%) responded to R-GDP therapy, whereas only 6 out of 16 refractory patients responded (37.5%). With regard to the duration of response, the response rates in 19 patients with late relapse (at least 12 months) and 6 with early relapse (less than 12 months) were 94.7% and 83.3% (p = 0.43). Overall, the 2-year PFS and OS rates were 48.8% and 74.2%, respectively. 18 responders underwent ASCT with a 2-year PFS after ASCT of 61.2%. Although CAR-T is recommended in patients with Rel/Ref DLBCL, R-GDP is a realistic option given the limited availability of immediate CAR-T therapy. Further studies including genomic profiles are warranted to identify factors that can predict a response to R-GDP in Rel/Ref DLBCL.

Hypothalamic-Pituitary Axis Involvement in Primary Central Nervous System Lymphoma.

CONTEXT: Primary central nervous system lymphoma (PCNSL) is a rare malignancy that may involve the hypothalamic-pituitary axis (HPA), leading to underrecognized but clinically significant endocrine dysfunction. OBJECTIVE: This work aims to characterize the spectrum and patterns of HPA-related endocrine disturbances in patients with PCNSL. DATA SOURCES: A systematic search was conducted in PubMed, EMBASE, Scopus, and Web of Science, supplemented by gray literature. The search concluded in February 2025. STUDY SELECTION: We included studies reporting adult PCNSL cases with documented dysfunction of at least one hormonal axis. Exclusion criteria were preexisting hypopituitarism or lack of endocrine data. DATA EXTRACTION: Data on demographics, tumor localization, hormonal axes affected, radiological findings, treatment, and outcomes were extracted. Risk of bias was assessed using JBI tools. RESULTS: Ninety-nine cases met the inclusion criteria. Diffuse large B-cell lymphoma accounted for 84% of cases. Endocrine dysfunction included isolated adenohypophyseal involvement (46%), neurohypophyseal (8%), and combined (45%). The most affected pituitary axes were the gonadal and thyroid axes, with 89.7% and 89.2% involvement, respectively. Hypothalamic tumors were strongly associated with combined dysfunction (odds ratio = 9.47; 95% CI, 3.76-23.86; P < .001). Persistent endocrinopathy was more frequent in progressive disease. No direct association was found between endocrine dysfunction and mortality. CONCLUSION: HPA dysfunction in PCNSL is frequent and often underdiagnosed. Hypothalamic involvement is associated broader hormonal impairment. Routine hormonal screening and multidisciplinary management should be standard in PCNSL care to minimize complications and improve outcomes.

Targeted variant analysis of feline mediastinal lymphoma using MassARRAY and clinical associations.

Lymphoma is the most commonly diagnosed cancer in cats. This study used the Agena MassARRAY to genotype 40 variants across 17 genes in feline mediastinal lymphoma. These variants have previously been identified in tumors, including T- and B-cell lymphomas, acute and chronic lymphocytic leukemias, and mast cell tumors, in humans, dogs, and cats, using various methods. They were selected based on high prevalence reported in prior oncology studies, potential relevance to targeted therapy, and suitability for multiplex PCR amplification. Pleural fluid samples were collected from 76 cats with mediastinal lymphoma, including 69 domestic shorthairs, two Persians, two Siamese, two Wichienmaat, and one Scottish Fold. The most prevalent variants were found in the BCL2, KIT, STAT3, and ZEB1 genes. Specifically, BCL2 c.83275986G > A and c.83275992G > T were present in 71.1% and 57.9%, respectively. In cats with variant-positive in KIT c.163965724C > CT significantly reduced (11 days) compared to wild-type cats (94 days) (p < 0.001). In cats with variant-positive in STAT3 c.42942437C > CA, resulted in shorter median survival compared to wild-type cats (18 days vs. 77 days, p = 0.006). The findings suggest that the variant panel could be useful for the genomic landscape of feline mediastinal lymphoma and warrant further validation.

Venetoclax added to dose-adjusted EPOCH-R for newly diagnosed double-hit lymphomas: phase 2 results from ALLIANCE A051701, an open-label, randomised, controlled, phase 2-3 trial.

BACKGROUND: High-grade B-cell lymphoma with rearrangements of MYC and BCL2 and/or BCL6, known as double-hit lymphoma, is a highly aggressive malignancy with poor outcomes after standard chemoimmunotherapy. We aimed to study whether the addition of the BCL2-inhibitor venetoclax to chemoimmunotherapy in patients with double-hit lymphoma resulted in superior efficacy compared with chemotherapy alone. METHODS: ALLIANCE A051701 is an open-label, randomised, controlled, phase 2-3 trial in separate cohorts of patients with double-hit lymphoma and patients with double-expressor lymphoma. In this analysis, we report phase 2 results from the double-hit lymphoma cohort. Patients aged 18-80 years with newly diagnosed double-hit lymphoma and Eastern Cooperative Oncology Group (ECOG) performance status 0-2 were recruited from 41 hospitals and outpatient clinics in the USA. Patients were randomly assigned (1:1) to receive DA-EPOCH-R (dose-adjusted etoposide, prednisone, vincristine, cyclophosphamide, doxorubicin, and rituximab) either alone (DA-EPOCH-R group) or with venetoclax (DA-EPOCH-R plus venetoclax group) using permuted block randomisation schedule. All patients and investigators were aware of group assignment. DA-EPOCH-R was administered on a 21-day schedule for up to six total cycles. Venetoclax was given as 600 mg by mouth daily on days 4-8 of cycle 1 and on days 1-5 of cycles 2-6. The primary endpoint was progression-free survival in the modified intent-to-treat population inclusive of all eligible patients with centrally confirmed double-hit lymphoma. The safety analysis population consisted of all evaluable patients who received at least one dose of protocol treatment. This trial is registered with ClinicalTrials.gov (NCT03984448) and is closed to enrolment. FINDINGS: 36 patients were randomly assigned to the DA-EPOCH-R group and 37 to the DA-EPOCH-R plus venetoclax group between Oct 22, 2019, and Sept 18, 2020. Median age was 65 years (IQR 56-73) and baseline demographic factors were well balanced between groups, with 30 (45%) female and 36 (55%) male patients. Most patients (59 [89%]) were white, two (3%) were Asian, one (2%) was Black or African American, and four (6%) had unknown or unreported ethnicity. The majority of patients had MYC-BCL2 double-hit lymphoma (59 [89%] patients), advanced stage disease (57 [86%] patients), and high-intermediate/high-risk IPI score (42 [64%] patients). Median follow-up was 34·7 months (IQR 30·1-36·8). Median progression-free survival was 28·4 months (95% CI 5·2-not estimable) in the DA-EPOCH-R group (n=30) and 7·7 months (95% CI 4·7-NE) in the DA-EPOCH-R plus venetoclax group (n=36; hazard ratio [HR] 1·13, 95% CI 0·53-2·37; p=0·75). Deaths on treatment occurred in one (3%) patient in the DA-EPOCH-R group (due to dyspnoea; possibly related to treatment) and six (17%) patients in the DA-EPOCH-R plus venetoclax group (four due to sepsis [three at least possible related and one unrelated], two due to cardiac arrest [at least possibly related]), prompting early closure of the double-hit lymphoma cohort. The most common grade 3-4 non-haematological adverse event was febrile neutropenia, occurring in 15 (43%) of 35 patients in the DA-EPOCH-R plus venetoclax group and 11 (37%) of 30 patients in the DA-EPOCH-R group. The median overall survival has not been reached in either group. The 24-month overall survival estimates were 72% (95% CI 52-85) in the DA-EPOCH-R group compared with 52% (95% CI 33-68) in the DA-EPOCH-R plus venetoclax group (HR 2·49, 95% CI 1·03-6·04; p=0·038). INTERPRETATION: The addition of venetoclax to DA-EPOCH-R resulted in excess mortality, prompting early study closure. Robust accrual shows that prospective multicentre trials are feasible in double-hit lymphoma, and the outcomes in the DA-EPOCH-R group serve as a benchmark for future studies.

Clinical outcomes of Epstein-Barr virus infection/reactivation following CAR-T cell therapy: A systematic review.

BACKGROUND: Epstein-Barr virus (EBV) infection or reactivation is an emerging but underrecognized complication following chimeric antigen receptor T-cell (CAR-T) therapy and is likely associated with treatment-induced immune dysregulation. Data regarding its clinical impact remain limited. OBJECTIVE: To evaluate the reported occurrence, clinical manifestations, and outcomes of EBV infection or reactivation in adults undergoing CAR-T therapy. METHODS: A systematic review was conducted in accordance with the PRISMA 2020 guidelines. PubMed, Embase, and Cochrane CENTRAL were searched from inception to March 2025 for studies reporting EBV infection or reactivation after CAR-T therapy in adults. Due to limited and heterogeneous data, results were synthesized descriptively. RESULTS: Five studies comprising 80 patients were included (median age, 55 years; 52.6% male among patients with reported sex data [10/19]). Across the included studies, 11 EBV infection/reactivation events were identified among 80 described CAR-T recipients, representing 13.8% of the reported sample rather than a true incidence estimate. Among events with usable individualized timing data, the median interval from CAR-T infusion to EBV detection/reactivation was 9.8 months (approximate range, 1-44 months). Because EBV surveillance strategies and definitions were inconsistently reported across studies, this proportion should not be interpreted as a true incidence estimate. Four patients (36.4%) developed EBV-associated disease, including three cases of EBV-related lymphoproliferative disorder and one case of EBV-associated diffuse large B-cell lymphoma. Among seven patients with reported post-CAR-T treatment response, four achieved Complete Remission/ Continuous Complete Remission; treatment response should be interpreted separately from final survival status. Confirmed EBV-related mortality occurred in 2/11 patients with reported EBV infection/reactivation and in 2/4 patients with EBV-associated disease; all-cause mortality could not be reliably estimated because patient-level vital status could not be fully attributed to the EBV-reactivated subgroup. Reported toxicities predominantly consisted of low-grade cytokine-release syndrome; however, toxicity data were limited. CONCLUSION: Although infrequently reported, EBV infection or reactivation after CAR-T therapy may be associated with substantial morbidity and mortality among affected patients. However, the available evidence is limited by the small sample size, heterogeneous study designs, and inconsistent EBV surveillance practices.

Proteomic serum profiles before and after lipoprotein apheresis in patients with peripheral artery disease with ulceration.

INTRODUCTION: The efficacy of lipoprotein apheresis (LA) in peripheral arterial disease (PAD) has been primarily attributed to its anti-atherosclerotic effects through the adsorption of lipoproteins. However, the other potential effects of LA remain unknown. We evaluated changes in serum profiles before and after LA using a comprehensive analysis to explore the underlying mechanism. METHODS: Ten patients with leg ulcers were included from the LETS-PAD study, in which patients with lipoprotein-controlled PAD underwent LA. Serum samples collected at baseline and 1 month after LA were analyzed for proteomic changes. RESULTS: Six patients exhibited ulcer epithelialization and skin perfusion pressure improvement. Proteomic analysis identified 2033 proteins. Fifty-five proteins showed significant differences. B-cell lymphoma protein-2 associated X (BAX) and C-X-C motif chemokine 10 (CXCL10) were downregulated. CONCLUSION: Serum BAX and CXCL10 levels significantly decreased after LA, which may be involved in the ulcer epithelialization mechanism of LA, which potentially acts through angiogenesis promotion.

Acupoint Selection Patterns and Potential Mechanisms of Acupuncture in Knee Osteoarthritis: A Combined Data Mining and Network Pharmacology Study.

OBJECTIVE: To identify the core acupoint prescription and Kellgren-Lawrence (K-L) grade-dependent compatibility patterns of acupuncture for KOA through complex network analysis, and to predict the potential molecular mechanisms underlying the core prescription via network pharmacology. METHODS: Literature was retrieved from PubMed, EMbase, Cochrane Library, Web of Science, CNKI, Wanfang, VIP, and SinoMed (inception to September 3, 2025). Frequency, association rule, complex network, and K-L grade subgroup analyses were applied. Potential targets of the core prescription were identified via network pharmacology and intersected with disease targets from OMIM, Therapeutic Target, GeneCards, and DrugBank. A protein-protein interaction (PPI) network was constructed, and Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analyses were performed to explore the potential molecular mechanisms. RESULTS: We included 522 studies, yielding 582 prescriptions involving 123 acupoints. The core prescription comprised 24 acupoints, including Dubi (ST35), Neixiyan (EX-LE4), Liangqiu (ST34), Xuehai (SP10), Zusanli (ST36), Yanglingquan (GB34), Yinlingquan (SP9), among others. K-L subgroup analysis revealed ST35, GB34, SP9, and SP10 as universal core acupoints. The mild-to-moderate subgroup mainly used local acupoints, while the moderate-to-severe subgroup centered on ST35, with increased distal acupoint usage and higher degree values. Network pharmacology analysis identified 77 overlapping targets. Core targets included tumor necrosis factor (TNF), interleukin 6 (IL6), interleukin 1 beta (IL1B), tumor protein p53 (TP53), matrix metallopeptidase 9 (MMP9), signal transducer and activator of transcription 3 (STAT3), transforming growth factor beta 1 (TGFB1), caspase 3 (CASP3), and B-cell lymphoma 2 (BCL2), which were enriched in inflammation and immunity, cartilage metabolism, and tissue repair pathways. CONCLUSION: The core acupoint prescription for KOA features local acupoints combined with distal ones, exhibiting distinct patterns across K-L grades. Our computational findings suggest that core acupoints may potentially delay knee joint degeneration by synergistically regulating inflammation, cartilage metabolism, apoptosis, and tissue repair, although these predictions require experimental validation. These findings provide preliminary evidence and a theoretical basis for standardized clinical point selection and further mechanistic research.

A Knowledge-Enhanced Multimodal Framework with Genomic Reconstruction for DLBCL Drug Response Prediction.

Diffuse large B-cell lymphoma (DLBCL) exhibits substantial biological heterogeneity, leading to pronounced variability in patient response to therapy. Accurate drug response prediction is therefore critical for precision treatment but remains challenging in clinical settings where genomic sequencing, a highly informative modality, is frequently incomplete. Existing methods, often developed from cell-line pharmacogenomic datasets or single-modality data, typically assume fully observed molecular profiles and thus show limited robustness under missing genomic data. To address this limitation, a knowledge-enhanced multimodal framework with genomic reconstruction (KeM-DRP) is proposed for individualized drug response prediction in DLBCL. The framework models the central role of genomics by integrating biological prior knowledge through a gene-pathway-biological process hierarchy, enabling robust representation learning from sparse observations. To compensate for missing genomic measurements, a cross-modal genomic compensation module reconstructs genomically informed latent features from routinely available clinical modalities. Furthermore, a genomics-guided adaptive fusion strategy dynamically integrates heterogeneous modalities conditioned on observed or reconstructed genomic representation. Experiments on a real-world DLBCL cohort demonstrate that KeM-DRP consistently outperforms competitive baselines. The reconstructed genomic representation represents most predictive utility, highlighting the robustness and practical value of the framework under incomplete genomic data.

A bivalent molecular glue linking lysine acetyltransferases to oncogene-induced cell death.

Developing cancer therapies that induce specific death of malignant cells is critical for preventing relapse. Highly effective strategies, such as immunotherapy, exemplify this principle. Here, we provide the mechanistic basis for a small-molecule approach that leverages chemically induced proximity (CIP) to kill diffuse large B cell lymphoma, the most common non-Hodgkin lymphoma. We developed lysine acetyltransferase (KAT)-based TCIPs (transcriptional/epigenetic chemical inducers of proximity), or KAT-TCIPs, which redirect p300/CREB-binding protein (CBP) to activate cell-death networks repressed by the oncogenic driver BCL6. Our lead KAT-TCIP reprograms the epigenome to initiate apoptosis. The crystal structure of the chemically induced p300-BCL6 complex reveals how chance protein-protein interactions may be exploited to confer the potency and selectivity of KAT-TCIPs. Thus, oncogenic drivers can be co-opted to activate robust cell death. Consistent with their gain-of-function mechanism, TCIPs recruiting different transcriptional activators-p300, BRD4, or CDK9-produce distinct genomic responses, suggesting specialized therapeutic uses.
