文摘Hodgkin lymphoma(HL)is a heterogenous lymphoproliferative disorder of B-cell origin and represents one of the most common malignancies in children and young adults.In addition to well-known underlying factors-such as Epstein-Barr virus infection-the familial aggregation demonstrated in large population studies suggested a genetic predisposition.First-degree relatives of patients with HL have an approximately threefold increased risk of developing the disease compared to the general population.These observations have recently prompted several whole-genome studies in affected families,identifying variants possibly implicated in lymphomagenesis,including alterations in DICER1(a member of the ribonuclease III family),POT1(protection of telomeres 1),KDR(kinase insert domain receptor),KLHDC8B(kelch domain-containing protein 8B),PAX5(paired box protein 5),GATA3(GATA binding protein 3),IRF7(interferon regulatory factor 7),EEF2KMT(eukaryotic elongation factor 2 lysine methyltransferase),and POLR1E(RNA polymerase I subunit E).In this article,we review current insights into the etiopathogenesis and risks of familial HL,and present case reports involving two sisters diagnosed with HL nearly 17 years apart.Recognizing the risk for first-degree relatives may potentially increase awareness of early symptoms among family members of HL patients,leading to earlier diagnosis and better outcomes.Conversely,understanding that the hereditary risk,though higher than in the general population,remains relatively low may provide reassurance for affected families.

文摘Objectives:B-cell lymphoma 6(BCL6)is a transcriptional repressor whose overexpression is closely linked to the progression of diffuse large B-cell lymphoma(DLBCL),making it a promising therapeutic target.This study aims to identify a novel small molecule,synthesized via proteolysis-targeting chimeras(PROTACs),capable of degrading BCL6,thereby inhibiting DLBCL growth and providing a foundation for future preclinical studies.Methods:The expression of BCL6 in DLBCL was analyzed using The Cancer Genome Atlas(TCGA)database and the Human Protein Atlas.Western blotting assays confirmed BCL6 expression in tumor cell lines,leading to the identification of the small molecule compound DZ-865B.To evaluate DZ-865B’s in vitro efficacy,multiple assays were performed,including protein immunoblotting,immunofluorescence,reverse transcription quantitative PCR,EDU proliferation,and soft agar cloning assays.Results:TCGA analysis revealed significant overexpression of BCL6 in DLBCL(p<0.05),corroborated by immunohistological staining and western blotting.DZ-865B induced BCL6 degradation in DLBCL cell lines(OCI-LY-1 and SU-DHL-4)in a concentration-and time-dependent manner,and induced the degradation of nuclear BCL6 through the ubiquitin-proteasome pathway.Notably,DZ-865B did not alter BCL6 mRNA levels but modulated downstream gene expression,leading to the activation of apoptosis pathway proteins and inhibition of DNA synthesis,effectively suppressing DLBCL cell growth.Conclusion:This study demonstrates that the small molecule DZ-865B targets and degrades BCL6 in DLBCL cells,promoting apoptosis and inhibiting cellular proliferation.These findings highlight DZ-865B as a potential therapeutic agent for diffuse large B-cell lymphoma.
文摘In daily life,keyword spotting plays an important role in human-computer interaction.However,noise often interferes with the extraction of time-frequency information,and achieving both computational efficiency and recognition accuracy on resource-constrained devices such as mobile terminals remains a major challenge.To address this,we propose a novel time-frequency dual-branch parallel residual network,which integrates a Dual-Branch Broadcast Residual module and a Time-Frequency Coordinate Attention module.The time-domain and frequency-domain branches are designed in parallel to independently extract temporal and spectral features,effectively avoiding the potential information loss caused by serial stacking,while enhancing information flow and multi-scale feature fusion.In terms of training strategy,a curriculum learning approach is introduced to progressively improve model robustness fromeasy to difficult tasks.Experimental results demonstrate that the proposed method consistently outperforms existing lightweight models under various signal-to-noise ratio(SNR)conditions,achieving superior far-field recognition performance on the Google Speech Commands V2 dataset.Notably,the model maintains stable performance even in low-SNR environments such as–10 dB,and generalizes well to unseen SNR conditions during training,validating its robustness to novel noise scenarios.Furthermore,the proposed model exhibits significantly fewer parameters,making it highly suitable for deployment on resource-limited devices.Overall,the model achieves a favorable balance between performance and parameter efficiency,demonstrating strong potential for practical applications.

文摘Hepatitis C virus(HCV)and hepatitis B virus(HBV)infections are increasingly recognized as significant etiological factors in the pathogenesis of B-cell non-Hodgkin’s lymphomas(B-NHLs).Epidemiological and molecular studies have demonstrated a consistent association between chronic viral infection and B-NHLs.Multiple pathogenic mechanisms have been implicated in lymphomagenesis,both direct and indirect,including chronic antigenic stimulation,direct infection of B cells,and viral protein-mediated oncogenic signaling,It is likely that a combination of several pathogenic conditions is required to eventually lead to the development of lymphoma.The prevalence of B-cell lymphomas among individuals with chronic HCV or HBV infection presents a complex pathogenetic scenario,given the tumor heterogeneity and variable clinical behavior,and poses therapeutic challenges,due to the partial efficacy of current treatment options.The advent of direct-acting antivirals(DAAs)for HCV and high-genetic barrier nucleos(t)ide analogues(NAs)for HBV has improved patient outcomes.In indolent HCV-associated B-NHLs,antiviral therapy with DAAs alone often achieves sustained virologic response and may lead to lymphoma regression.Conversely,aggressive subtypes like diffuse large B-cell lymphomas require combination treatment with immunochemotherapy.In the setting of HBV-associated lymphomas,antiviral prophylaxis with potent NAs(e.g.,entecavir or tenofovir)is essential to prevent HBV reactivation during rituximab-containing chemotherapy regimen.The integration of antiviral and anticancer therapies has been shown to enhance survival outcomes while mitigating hepatic toxicity.A comprehensive understanding of the biological interplay between chronic viral infection and B-cell transformation is critical for optimizing diagnostic and therapeutic strategies.Aim of this viewpoint is to provide evidence that early viral detection and prompt management remain the most effective strategies to improve survival rates and to reduce treatment-related morbidity in these patients.

文摘Classical Hodgkin lymphoma(cHL)is characterized by rare Hodgkin/Reed-Sternberg(HRS)tumor cells that uniformly express cluster of differentiation(CD)30 molecules and orchestrate an immunosuppressive tumor microenvironment,making CD30 an attractive and selective therapeutic target.We summarize the biological rationale for CD30 as a therapeutic target and the preclinical and clinical evidence across major platforms:antibody-drug conjugates(brentuximab vedotin),monoclonal antibodies(including acimtamig and its combinations with Natural Killer cells),second-and third-generation chimeric antigen receptor(CAR)-T cells,and alternative modalities.Particular attention is given to standardized response assessment(IWG,Lugano,RECIL criteria),which enables appropriate cross-trial comparisons.Taken together,the data indicate that beyond the established role of brentuximab vedotin,CD30-directed CAR-T cells and bispecific antibodies demonstrate high activity in refractory cHL,especially when used with fludarabine-containing lymphodepletion,combined with programmed cell death 1(PD-1)receptor blockade as a strategy to eradicate minimal residual disease.Key challenges include durable effector-cell persistence and optimization of sequencing and combinations;notably,loss of CD30 as an escape mechanism appears uncommon.Integrating mechanistic insights into HRS biology with clinical trial data highlights strategies to enhance the efficacy,safety,and accessibility of CD30-directed immunotherapy.This review aims to provide a concise overview of CD30-targeted approaches in cHL,emphasizing therapeutic outcomes and the evolution of CAR-T technologies.

文摘Background:The prognostic significance of the chemokine receptor CCR7 in diffuse large B-cell lymphoma(DLBCL)has been reported previously.However,the detailed mechanisms of CCR7 in DLBCL,particularly regarding its interaction with lenalidomide treatment,are not fully understood.Methods:Our study utilized bioinformatics approaches to identify hub genes in SU-DHL-2 cell lines treated with lenalidomide compared to control groups.Immunohistochemical data and clinical information from 122 patients with DLBCL were analyzed to assess the correlation of CCR7 and p-ERK1/2 expression with the prognosis of DLBCL.Furthermore,in vitro and in vivo experiments were conducted to clarify the role of CCR7 in the response of DLBCL to lenalidomide treatment.Results:Our bioinformatics analysis pinpointed CCR7 as a hub gene in the context of lenalidomide treatment in DLBCL.Notably,31.14%and 36.0%(44/122)of DLBCL cases showed positive expression for CCR7 and ERK1/2 respectively,establishing them as independent prognostic factors for adverse outcomes in DLBCL via multivariate Cox regression analysis.Additionally,our studies demonstrated that the external application of the protein CCL21 promoted proliferation,migration,invasion,and activation of the ERK1/2 pathway in SU-DHL-2 and OCI-LY3 cell lines with high levels of CCR7 expression.This effect was mitigated by CCR7 silencing through siRNA,application of ERK inhibitors,or lenalidomide treatment.In vivo experiments reinforced the efficacy of lenalidomide,significantly reducing tumor growth rate,tumor mass,serum total LDH levels,and expression of CCR7 and p-ERK1/2 in a SUDHL-2 xenograft model in nude mice(p<0.05).Conclusion:Our study clarifies the potential role of the CCL21/CCR7/ERK1/2 axis in the therapeutic effects of lenalidomide in DLBCL treatment.
文摘BACKGROUND Primary cardiac lymphoma(PCL)is a rare subset of cardiac tumors,often diagnosed late due to nonspecific symptoms.It predominantly affects immunocompromised individuals,primarily in the pericardium and right heart.Late diagnosis mimics common cardiac ailments,leading to poor prognosis.AIM To systematically review the efficacy of rituximab in treating PCL either alone or in various chemotherapeutic regimens.Secondary objectives include evaluating morphological subtypes,assessing treatment regimens,and analyzing outcomes focusing on remission and adverse events.METHODS Following PRISMA guidelines,a comprehensive literature search was conducted across multiple databases,including PubMed,Hinari,Web of Science,and Scopus.English-language studies reporting the use of rituximab in treating PCL in humans were included.Study selection involved initial screening of titles and abstracts followed by full-text examination and data extraction.RESULTS Thirty-three case reports involving 36 patients were included in this systematic review.Diffuse large B-cell lymphoma was the predominant morphological subtype observed.The rituximab,cyclophosphamide,doxorubicin,oncovin,and prednisolone regimen emerged as the most commonly employed treatment strategy,indicating widespread acceptance and efficacy in PCL management.Combination therapies,including surgical intervention,showed promise in achieving complete remission,while some studies reported mortality despite aggressive treatment approaches.CONCLUSION Rituximab,particularly in combination with chemotherapy regimens,represents a significant advancement in PCL management,offering hope for improved patient outcomes.However,challenges such as variable treatment responses and adverse events underscore the complexity of managing PCL.Further research is warranted to refine therapeutic strategies and enhance diagnostic approaches for this rare cardiac malignancy.

文摘BACKGROUND Mantle cell lymphoma(MCL)is an aggressive B-cell non-Hodgkin lymphoma that rarely presents with cutaneous involvement,which typically occurs in advanced disease stages.Primary cutaneous manifestations are particularly uncommon and frequently misdiagnosed.We report a diagnostically challenging case of MCL that first appeared as a nodule on the lower leg.CASE SUMMARY An elderly female had a painless red nodule on the front of her right lower leg for six months.Positron emission tomography-computed tomography showed a soft tissue mass at the same site and increased activity in the right groin lymph nodes.Skin and lymph node biopsies,along with immunostaining,confirmed MCL.The patient began combination chemotherapy,resulting in a marked improvement of skin lesions and lymphadenopathy after two weeks.CONCLUSION Cutaneous manifestations,though uncommon,may serve as the initial clinical presentation of MCL.Dermatologists and pathologists should maintain heigh-tened awareness of this diagnostic possibility when evaluating persistent,atypical cutaneous nodules,particularly in elderly patients.Histopathological evaluation with complete immunophenotypic profiling is paramount for accurate diagnosis.
文摘BACKGROUND The concept of“duodenal-type follicular lymphoma(FL)”has already been established as a disease entity.On the other hand,because FL that develops in the colorectum is a rare disease,its clinical characteristics,including its treatment and outcome,are poorly understood.AIM To clarify the characteristic clinical features of colorectal FL.METHODS We identified 5 patients with FL from December 2010 to July 2022 whose colorectal lesions were confirmed by endoscopic biopsy at our hospital and retrospectively examined their clinical features,including endoscopic findings,treatment,and long-term outcomes.RESULTS The median age of the patients was 70 years(range 62-74 years,3 males and 2 females),and 2 patients were considered to have systemic FL lesions.Endoscopic findings revealed elavated lesions in all 5 patients(polypoid 3,flat elavated 1,papular 1).Only 1 patient underwent therapeutic intervention,and 4 patients chose watchful waiting.Except for 1 patient in which the lesion spontaneously regressed,the disease recurred or progressed in 4 patients,3 of whom eventually achieved near complete remission with the administration of rituximab and bendamustine(±polatuzumab vedotin).The 5 patients in this study were still alive or exhibited long-term survival before death;the survival time ranged from 8-29 years after the onset of lymphoma.CONCLUSION In the present study,colorectal FL progressed slowly,and overall survival was good because it was sensitive to anticancer drugs even after the disease progressed without initial therapeutic intervention.
文摘BACKGROUND Mucosa-associated lymphoid tissue(MALT)lymphoma is a subtype of extranodal marginal zone lymphoma,typically occurring in mucosal sites such as the stomach,salivary glands,and lungs.This study aims to analyze the demographic and clinicopathologic characteristics of patients with gastric MALT lymphoma in the United States and evaluate the interaction between age and gender on survival outcomes.AIM To analyze the demographic and clinicopathologic characteristics of patients with gastric MALT lymphoma in the United States and evaluate the interaction between age and gender on survival outcomes.METHODS A retrospective cohort study was conducted using the Surveillance,Epidemiology,and End Results(SEER)database,which included 2453 patients diagnosed with MALT lymphoma from 2010 to 2021.Data were analyzed for demographic factors,tumor characteristics,treatment modalities,and survival outcomes.A Cox proportional hazards regression model was used to identify predictors of overall mortality and cancer-specific mortality.RESULTS The study predominantly included Non-Hispanic White patients(62.78%),with nearly equal gender distribution(50.31%females,49.69%males),and most diagnoses occurring in individuals aged 60-79 years.The majority of tumors were localized(80.07%).Multivariate analysis identified older age,male gender,advanced tumor stage,and socioeconomic factors—such as annual income and marital status—as independent predictors of mortality.No significant interaction between age and gender on mortality outcomes was observed.CONCLUSION Sociodemographic factors,including advanced age,male gender,annual income,and marital status,as well as advanced tumor stage,significantly impacted survival outcomes in patients with MALT lymphoma.Radiotherapy was associated with a reduction in overall mortality.Early detection is crucial for optimizing outcomes,as localized disease responds well to available treatment modalities.
文摘BACKGROUND T/histiocyte-rich large B-cell lymphoma(T/HRBCL)is a highly aggressive subtype of diffuse large B-cell lymphoma characterized histologically by the presence of a few neoplastic large B cells amidst an abundant background of reactive T lymphocytes and/or histiocytes.T/HRBCL commonly affects the lymph nodes,followed by extranodal sites,such as the spleen,liver,and bone marrow,with rare occurrences in the gastrointestinal tract.Primary gastrointestinal T/HRBCL lacks specific clinical and endoscopic manifestations,and it is difficult to differentiate from inflammatory diseases,nodular lymphocyte predominant Hodgkin lymphoma,and other diseases on a histological basis,thereby hindering early diagnosis.CASE SUMMARY A 63-year-old man was hospitalized with a one-month history of jaundice and weight loss of approximately 3 kg.Laboratory tests revealed increased hepatic parameters in a cholestatic pattern and elevated carbohydrate antigen 19-9 levels.An abdominal computed tomography scan revealed a low-density mass within the descending duodenum and dilation of the bile and pancreatic ducts.He was clinically diagnosed with a duodenal tumor.During surgery,a 7.0 cm×8.0 cm mass was identified within the descending duodenum,so pancreaticoduodenectomy and cholecystectomy were performed.Following operative biopsy,the tumor was diagnosed as primary duodenal T/HRBCL.The patient refused postoperative chemotherapy and died four months after surgery.CONCLUSION Primary duodenal T/HRBCL is an extremely rare and highly aggressive malignancy.The initial treatment strategies should be based on the original site of the tumor,the disease stage,and the patient's physical condition.Chemotherapy-based comprehensive treatment is still the main treatment method for primary gastrointestinal T/HRBCL.

文摘Background:Primary bone marrow diffuse large B-cell lymphoma(PBM-DLBCL)represents an uncommon yet clinically aggressive hematologic malignancy.Despite its significant clinical impact,this entity lacks standardized diagnostic criteria in current WHO classifications.Methods:We performed a retrospective analysis of 55 PBM-DLBCL cases from our institutional database and published literature(2001–2022)to characterize disease features and identify prognostic factors,with particular focus on assessing how different treatment regimens influence therapeutic efficacy and long-term outcomes.Results:The data suggested a potential link between international prognostic index(IPI)scores and poorer survival,albeit without conclusive statistical evidence(p 0.05).Treatment=response emerged as a significant prognostic factor,and patients with complete response(CR)demonstrating superior survival in Cox univariate and multivariate analysis(p 0.001).Intensive therapeutic regimens were associated with<improved clinical outcomes compared to conventional therapies.While incorporating rituximab into conventional chemotherapy regimens has demonstrated superior clinical outcomes compared to chemotherapy alone in PBM-DLBCL patients.Conclusion:Our findings highlight the aggressive nature of PBM-DLBCL and underscore the importance of early recognition,risk stratification,and optimized treatment selection for this rare disease entity.
文摘Objective:This study aimed to investigate the epidemiological characteristics and treatment regimens of non-Hodgkin lymphoma(NHL)in China through a retrospective analysis of 9,064 NHL cases.Methods:Clinical data of 9,064 patients were collected from 555 hospitals in 28 provinces of China.Results:Among 9,064 NHL patients,there were 5,241 males(57.8%)and 3,823 females(42.2%),with a male-to-female ratio of 1.37:1.Patients aged≥45 years accounted for 89.6%,with a mean age of 61.87±13.30 years.The predominant NHL subtypes were diffuse large B-cell lymphoma(DLBCL,45.2%),chronic lymphocytic leukemia/small lymphocytic lymphoma(CLL/SLL,19.8%),marginal zone lymphoma(MZL,13.9%),mantle cell lymphoma(MCL,9.7%),and central nervous system lymphoma(CNSL,4.3%).Combination therapy served as the primary treatment modality across all NHL subtypes.Conclusions:NHL in China demonstrates male predominance and primarily affects middle-aged and elderly populations,with combination chemotherapy remaining the mainstay therapeutic approach.

文摘BACKGROUND Childhood intestinal lymphoma is characterized by its insidious onset and the absence of specific clinical symptoms.The thinner abdominal wall in children significantly aids in the ultrasound visualization of the abdominal cavity and intestines.Although many typical cases of intestinal lymphoma can be diagnosed through ultrasound,physicians often either overlook these values or assume that ultrasound has limited diagnostic value for intestinal lymphoma.AIM To clarify the diagnosis of intestinal lymphoma and classify its severity using ultrasound,as well as to correlate this with prognosis.METHODS The correlation between ultrasound diagnostic outcomes,laboratory indicators,and clinical prognosis was analyzed to demonstrate the effectiveness of ultrasound in assessing the severity of intestinal lymphoma and to provide new evidence for the diagnosis and treatment of the disease in children.A retro-spective analysis was conducted on the sonographic images and case data of 28 children diagnosed with intestinal lymphoma and confirmed by surgical pathology.Additionally,we sought to determine the correlation between ultrasonic classification of lymphoma,lactate dehydrogenase(LDH)values,pathological classification,and prognosis.RESULTS Ultrasound was utilized to categorize 28 cases of intestinal lymphoma into focal segmental(15 cases)and extensive(13 cases)types.Ultrasound classification and LDH levels were significantly correlated with prognosis(P<0.05),while pathological type,age,gender,and treatment modality showed no significant correlation(P>0.05).Among ultrasound manifestations,there was a significant difference in LDH levels between the segmental and extensive groups(P<0.05).The prognosis for children with extensive intestinal lymphoma was poorer than that for children with localized segmental intestinal lymphoma(P<0.05).CONCLUSION Ultrasound can be used in the diagnosis and classification of intestinal lymphoma in children.Extensive intestinal lymphoma is associated with significantly elevated LDH and poor prognosis.

文摘BACKGROUND Primary testicular lymphoma(PTL)is a rare,aggressive malignancy,representing a small fraction of testicular tumors and non-Hodgkin lymphomas,yet it is the most common testicular malignancy in older men.Diffuse large B-cell lymphoma(DLBCL),which is typically the aggressive subtype,dominates PTL and shows diffuse B-cell infiltration.Venous tumor thrombus,uncommon in lymphomas,is uniquely reported in this case of testicular DLBCL with gonadal vein involvement.CASE SUMMARY A 62-year-old man presented with a two-month history of painless left testicular swelling and stiffness.Diagnostic imaging[ultrasonography,computed tomography(CT),and 18F-fluorodeoxyglucose positron emission tomography/CT(18FFDG-PET/CT)]revealed bilateral testicular masses and a gonadal vein tumor thrombus(SUVmax 16.5).Left orchiectomy confirmed DLBCL with CD20,Bcl-2,and MUM1 positivity(Ki-67:approximately 80%).The disease was staged as Ann Arbor stage IVA(International Prognostic Index score 3,high-intermediate risk).The patient received Rituximab,Polatuzumab Vedotin,Cyclophosphamide,Epirubicin,and Prednisolone chemotherapy,completing the first cycle with good tolerability.No adverse events were reported,and follow-up is ongoing to assess long-term outcomes.This case highlights the diagnostic utility of 18F-FDGPET/CT and the importance of multidisciplinary management in rare PTL presentations with tumor thrombus.CONCLUSION This case demonstrates the diagnostic complexities of PTL with gonadal vein tumor thrombus,underscoring the importance of considering lymphoma in elderly patients with testicular masses and venous involvement.A multi-disciplinary team including urologists,hematologists,and radiation oncologists is needed to ensure appropriate therapy.
